+# -------------- CodeIgniter Testing (4/20/2011) -------------- #
+
+
+# Introduction:
+
+This is the preliminary CodeIgniter testing documentation. It
+will cover both internal as well as external APIs and the reasoning
+behind their implemenation, where appropriate. As with all CodeIgniter
+documentation, this file should maintain a mostly human readable
+format to facilitate clean api design. [see http://arrenbrecht.ch/testing/]
+
+*FIRST PUBLIC DRAFT: EVERYTHING IS SUBJECT TO CHANGE*
+
+# Test Suites:
+
+CodeIgniter bootstraps a request very directly, with very flat class
+hierarchy. As a result, there is no main CodeIgniter class until the
+controller is instantiated.
+
+This has forced the core classes to be relatively decoupled, which is
+a good thing. However, it makes that portion of code relatively hard
+to test.
+
+Right now that means we'll probably have two core test suites, along
+with a base for application and package tests. That gives us:
+
+1. Bootstrap Test	- test common.php and sanity check codeigniter.php		[in planning]
+2. System Test		- test core components in relative isolation			[in development]
+3. Application Test	- bootstrapping for application/tests					[not started]
+4. Package Test		- bootstrapping for <package>/tests						[not started]
+
+
+## 1. Bootstrap Test
+
+Testing common.php should be pretty simple. Include the file, and test the
+functions. May require some tweaking so that we can grab the statics from all
+methods (see is_loaded()). Testing the actual CodeIgniter.php file will most
+likely be an output test for the default view, with some object checking after
+the file runs. Needs consideration.
+
+
+## 2. System Test
+
+Testing the core system relies on being able to isolate the core components
+as much as possible. A few of them access other core classes as globals. These
+should be mocked up and easy to manipulate.
+
+All functions in common.php should be a minimal implementation, or and mapped
+to a method in the test's parent class to gives us full control of their output.
+
+
+### CodeIgniterTestCase Documentation
+
+
+Test cases should extend CodeIgniterTestCase. This internally
+extends PHPUnit_Framework_TestCase, so you have access to all
+of your usual PHPUnit methods.
+
+We need to provide a simple way to modify the globals and the
+common function output. We also need to be able to mock up
+the super object as we please.
+
+Current API is *not stable*. Names and implementations will change.
+
+$this->ci_instance($obj)
+	set the object to use as the "super object", in a lot
+	of cases this will be a simple stdClass with the attributes
+	you need it to have.
+
+$this->ci_set_instance_var($name, $val)
+	add an attribute to the super object. This is useful if you
+	set up a simple instance in setUp and then need to add different
+	class mockups to your super object.
+
+$this->ci_core_class($name)
+	Get the _class name_ of a core class, so that you can instantiate
+	it. The variable is returned by reference and is tied to the correct
+	$GLOBALS key. For example:
+	$cfg =& $this->ci_core_class('cfg'); // returns 'CI_Config'
+	$cfg = new $cfg;					// instantiates config and overwrites the CFG global
+
+$this->ci_set_core_class($name, $obj);
+	An alternative way to set one of the core globals.
+
+
+## 3. Application Test:
+
+Not sure yet, needs to handle:
+- Libraries
+- Helpers
+- Models
+- MY_* files
+- Controllers (uh...?)
+- Views? (watir, selenium, cucumber?)
+
+- Database Testing
+
+
+## 4. Package Test:
+
+I don't have a clue how this will work.
+
+Needs to be able to handle packages
+that are used multiple times within the application (i.e. EE/Pyro modules)
+as well as packages that are used by multiple applications (library distributions)

+<h1>Tutorial - Conclusion</h1>
+
+<p>This tutorial did not cover all of the things you might expect of a full-fledged content management system, but it introduced you to the more important topics of routing, writing controllers, and models. We hope this tutorial gave you an insight into some of CodeIgniter's basic design patterns, which you can expand upon.</p>
+
+<p>Now that you've completed this tutorial, we recommend you check out the rest of the documentation. CodeIgniter is often praised because of its comprehensive documentation. Use this to your advantage and read the "Introduction" and "General Topics" sections thoroughly. You should read the class and helper references when needed.</p>
+
+<p>Every intermediate PHP programmer should be able to get the hang of CodeIgniter within a few days.</p>
+
+<p>If you still have questions about the framework or your own CodeIgniter code, you can:</p>

+<h1>Tutorial - Create news items</h1>
+
+<p>You now know how you can read data from a database using CodeIgnite, but you haven't written any information to the database yet. In this section you'll expand your news controller and model created earlier to include this functionality.</p>
+
+<h2>Create a form</h2>
+
+<p>To input data into the database you need to create a form where you can input the information to be stored. This means you'll be needing a form with two fields, one for the title and one for the text. You'll derive the slug from our title in the model. Create the new view at <dfn>application/views/news/create.php</dfn>.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="16">
+<h2>Create a news item</h2>
+
+&lt;?php echo validation_errors(); ?>
+
+&lt;?php echo form_open('news/create') ?>
+
+	<label for="title">Title</label> 
+	<input type="input" name="title" /><br />
+
+	<label for="text">Text</label>
+	<textarea name="text">&lt;/textarea><br />
+	
+	<input type="submit" name="submit" value="Create news item" /> 
+
+&lt;/form>
+</textarea>
+
+<p>There are only two things here that probably look unfamiliar to you: the <dfn>form_open()</dfn> function and the <dfn>validation_errors()</dfn> function.</p>
+
+<p>The first function is provided by the <a href="../helpers/form_helper.html">form helper</a> and renders the form element and adds extra functionality, like adding a hidden <a href="../ibraries/security.html">CSFR prevention field</a>. The latter is used to report errors related to from validation.</p>
+
+<p>Go back to your news controller. You're going to do two things here, check whether the form was submitted and whether the submitted data passed the validation rules. You'll use the <a href="../libraries/form_validation.html">form validation</a> library to do this.</p>
+
+<pre>
+function create()
+{
+	$this->load->helper('form');
+	$this->load->library('form_validation');
+	
+	$data['title'] = 'Create a news item';
+	
+	$this->form_validation->set_rules('title', 'Title', 'required');
+	$this->form_validation->set_rules('text', 'text', 'required');
+	
+	if ($this->form_validation->run() === FALSE)
+	{
+		$this->load->view('templates/header', $data);	
+		$this->load->view('news/create');
+		$this->load->view('templates/footer');
+		
+	}
+	else
+	{
+		$this->news_model->set_news();
+		$this->load->view('news/success');
+	}
+	
+}
+</pre>
+
+<p>The code above adds a lot of functionality. The first few lines load the form helper and the form validation library. After that, rules for the form validation are set. The <var>set_rules()</var> method takes three arguments; the name of the input field, the name to be used in error messages, and the rule. In this case the title and text fields are required.</p>
+
+<p>CodeIgniter has a powerful form validation library as demonstrated above. You can read <a href="../libraries/form_validation.html">more about this library here</a>.</p>
+
+<p>Continuing down, you can see a condition that checks whether the form validation ran successfully. If it did not, the form is displayed, if it was submitted <strong>and</strong> passed all the rules, the model is called. After this, a view is loaded to display a success message. Create a view at <dfn>application/view/news/success.php</dfn> and write a success message.</p>
+
+<h2>Model</h2>
+
+<p>The only thing that remains is writing a method that writes the data to the database. You'll use the Active Record class to insert the information and use the input library to get the posted data. Open up the model created earlier and add the following:</p>
+
+<pre>
+function set_news()
+{
+	$this->load->helper('url');
+	
+	$slug = url_title($this->input->post('title'), 'dash', TRUE);
+	
+	$data = array(
+		'title' => $this->input->post('title'),
+		'slug' => $slug,
+		'text' => $this->input->post('text')
+	);
+	
+	return $this->db->insert('news', $data);
+	
+}
+</pre>
+
+<p>This new method takes care of inserting the news item into the database. The third line contains a new function, <dfn>url_title()</dfn>. This function - provided by the <a href="../helpers/url_helper.html">URL helper</a> - strips down the string you pass it, replacing all spaces by dashes (-) and makes sure everything is in lowercase characters. This leaves you with a nice slug, perfect for creating URIs.</p>
+	
+<p>Let's continue with preparing the record that is going to be inserted later, inside the <var>$data</var> array. Each element corresponds with a column in the database table created earlier. You might notice a new method here, namely the <dfn>post()</dfn> method from the <a href="../libraries/input.html">input library</a>. This method makes sure the data is sanitized, protecting you from nasty attacks from others. The input library is loaded by default. At last, you insert our <var>$data</var> array into our database.</p>
+
+<h2>Routing</h2>
+
+<p>Before you can start adding news items into your CodeIgniter application you have to add an extra rule to <dfn>config/routes.php</dfn> file. Make sure your file contains the following. This makes sure CodeIgniter sees 'update' as a method instead of a news item's slug.</p>
+	
+<pre>
+$route['news/create'] = 'news/create';
+$route['news/(:any)'] = 'news/view/$1';
+$route['news'] = 'news';
+$route['(:any)'] = 'pages/view/$1';
+$route['default_controller'] = 'pages/view';
+</pre>
+
+<p>Now point your browser to your local development environment where you installed CodeIgniter and add <dfn>index.php/news/create</dfn> to the URL. Congratulations, you just created your first CodeIgniter application! Add some news and check out the different pages you made.</p>

+<h1>Tutorial - Hard coded pages</h1>
+
+<p>The first thing we're going to do is setting up a controller to handle our hard coded pages. A controller is a class with a collection of methods that represent the different actions you can perform on a certain object. In our case, we want to be able to view a page.</p>
+
+<p class="important"><strong>Note:</strong> This tutorial assumes you've downloaded CodeIgniter and installed the framework in your development environment.</p>
+
+<p>Create a file at <dfn>application/controllers/pages.php</dfn> with the following code.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="9">
+&lt;?php
+class Pages extends CI_Controller {
+
+	function view($page = 'home')
+	{
+
+	}
+}
+</textarea>
+
+<p>If you're familiar with PHP classes you see that we create a Pages class with a view method that accepts one parameter, <var>$page</var>. Another interesting observation is that the Pages class is extending the CI_Controller class. This means that the new Pages class can access the methods and variables defined in the CI_Controller class. When you look at this class in <dfn>system/core/controller.php</dfn> you can see this class is doing something really important; assigning an instance from the CodeIgniter super object to the <var>$this</var> object. In most of your code, <var>$this</var> is the object you will use to interact with the framework.</p>
+
+<p>Now we've created our first method, it is time to do some basic templating. For this tutorial, we will be creating two views to acts as our footer and header. Let's create our header at <dfn>application/views/templates/header.php</dfn> and ad the following code.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="8">
+<html>
+<head>
+	<title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
+</head>
+<body>
+	<h1>CodeIgniter 2 Tutorial</h1>
+	
+</textarea>
+
+<p>Our header doesn't do anything exciting. It contains the basic HTML code that we will want to display before loading the main view. You can also see that we echo the <var>$title</var> variable, which we didn't define. We will set this variable in the Pages controller a bit later. Let's go ahead and create a footer at <dfn>application/views/templates/footer.php</dfn> that includes the following code.</p>
+	
+<textarea class="textarea" style="width:100%" cols="50" rows="4">
+<strong>&copy; 2011</strong>	
+</body>
+</html>
+</textarea>
+
+<h2>Adding logic to the controller</h2>
+
+<p>Now we've set up the basics so we can finally do some real programming. Earlier we set up our controller with a view method. Because we don't want to write a separate method for every page, we made the view method accept one parameter, the name of the page. These hard coded pages will be located in <dfn>application/views/pages/</dfn>. Create two files in this directory named <dfn>home.php</dfn> and <dfn>about.php</dfn> and put in some HTML content.</p>
+
+<p>In order to load these pages we'll have to check whether these page actually exists. When the page does exist, we load the view for that pages, including the header and footer and display it to the user. If it doesn't, we show a "404 Page not found" error.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="16">
+function view($page = 'home')
+{
+			
+	if ( ! file_exists('application/views/pages/' . $page . EXT))
+	{
+		show_404();
+	}
+	
+	$data['title'] = ucfirst($page);
+	
+	$this->load->view('templates/header', $data);
+	$this->load->view('pages/' . $page);	
+	$this->load->view('templates/footer');
+	
+}	
+</textarea>
+
+<p>The first thing we do is checking whether the page we're looking for does actually exist. We use PHP's native file_exists() to do this check and pass the path where the file is supposed to be. Next is the function show_404(), a CodeIgniter function that renders the default error page and sets the appropriate HTTP headers.</p>
+
+<p>In the header template you saw we were using the <var>$title</var> variable to customize our page title. This is where we define the title, but instead of assigning the value to a variable, we assign it to the title element in the <var>$data</var> array. The last thing we need to do is loading the views in the order we want them to be displayed. We also pass the <var>$data</var> array to the header view to make its elements available in the header view file.<p> 
+	
+<h2>Routing</h2>
+
+<p>Actually, our controller is already functioning. Point your browser to <dfn>index.php/pages/view</dfn> to see your homepage. When you visit <dfn>index.php/pages/view/about</dfn> you will see the about page, again including your header and footer. Now we're going to get rid of the pages/view part in our URI. As you may have seen, CodeIgniter does its routing by the class, method and parameter, separated by slashes.</p>
+
+<p>Open the routing file located at <dfn>application/config/routes.php</dfn> and add the following two lines. Remove all other code that sets any element in the <var>$route</var> array.</p>
+	
+<textarea class="textarea" style="width:100%" cols="50" rows="3">
+$route['(:any)'] = 'pages/view/$1';
+$route['default_controller'] = 'pages/view';
+</textarea>
+
+<p>CodeIgniter reads its routing rules from top to bottom and routes the request to the first matching rule. These routes are stored in the <var>$route</var> array where the keys represent the incoming request and the value the path to the method, as described above.</p> 
+
+<p>The first rule in our <var>$routes</var> array matches every request - using the wildcard operator <dfn>(:any)</dfn> - and passes the value to the view method of the pages class we created earlier. The default controller route makes sure every request to the root goes to the view method as well, which has the first parameter set to 'home' by default.</p>

+<h1>Tutorial &minus; News section</h1>
+
+<p>In the last section, we went over some basic concepts of the framework by writing a class that includes static pages. We cleaned up the URI by adding custom routing rules. Now it's time to introduce dynamic content and start using a database.</p>
+
+<h2>Setting up your model</h2>
+
+<p>Instead of writing database operations right in the controller, queries should be placed in a model, so they can easily be reused later. Models are the place where you retrieve, insert, and update information in your database or other data stores. They represent your data.</p>
+
+<p>Open up the <dfn>application/models</dfn> directory and create a new file called <dfn>news_model.php</dfn> and add the following code. Make sure you've configured your database properly as described <a href="../database/configuration.html">here</a>.</p>
+
+<pre>
+&lt;?php
+class News_model extends CI_Model {
+
+	function __construct()
+	{
+		$this->load->database();
+
+	}
+}
+</pre>
+
+<p>This code looks similar to the controller code that was used earlier. It creates a new model by extending CI_Model and loads the database library. This will make the database class available through the <var>$this->db</var> object.</p>
+
+<p>Before querying the database, a database schema has to be created. Connect to your database and run the SQL command below. Also add some seed records.</p>
+
+<pre>
+CREATE TABLE news (
+	id int(11) NOT NULL AUTO_INCREMENT,
+	title varchar(128) NOT NULL,
+	slug varchar(128) NOT NULL,
+	text text NOT NULL,
+	PRIMARY KEY (id),
+	KEY slug (slug)
+);
+</pre>
+
+<p>Now that the database and a model have been set up, you'll need a method to get all of our posts from our database. To do this, the database abstraction layer that is included with CodeIgniter — <a href="../database/active_record.html">ActiveRecord</a> — is used. This makes it possible to write your 'queries' once and make them work on <a href="../general/requirements.html">all supported database systems</a>. Add the following code to your model.</p>
+
+<pre>
+function get_news($slug = FALSE)
+{
+	if ($slug === FALSE)
+	{
+		$query = $this->db->get('news');
+		return $query->result_array();
+
+	}
+	else
+	{
+		$query = $this->db->get_where('news', array('slug' => $slug));
+		return $query->row_array();
+
+	}
+
+}
+</pre>
+
+<p>With this code you can perform two different queries. You can get all news records, or get a news item by its <a href="#" title="a URL friendly version of a string">slug</a>. You might have noticed that the <var>$slug</var> variable wasn't sanitized before running the query; Active Record does this for you.</p>
+
+<h2>Display the news</h2>
+
+<p>Now that the queries are written, the model should be tied to the views that are going to display the news items to the user. This could be done in our pages controller created earlier, but for the sake of clarity, a new "news" controller is defined. Create the new controller at <dfn>application/controllers/news.php</dfn>.</p>
+
+<pre>
+&lt;?php
+class News extends CI_Controller{
+
+	function __construct()
+	{
+		parent::__construct();
+		$this->load->model('news_model');
+
+	}
+
+	function index()
+	{
+		$data['news'] = $this->news_model->get_news();
+
+	}
+
+	function view($slug)
+	{
+		$data['news'] = $this->news_model->get_news($slug);
+
+	}
+
+}
+</pre>
+
+<p>Looking at the code, you may see some similarity with the files we created earlier. First, the "__construct" method: it calls the constructor of its parent class (<dfn>CI_Controller</dfn>) and loads the model, so it can be used in all other methods in this controller.</p>
+
+<p>Next, there are two methods to view all news items and one for a specific news item. You can see that the <var>$slug</var> variable is passed to the model's method in the second method. The model is using this slug to identify the news item to be returned.</p>
+
+<p>Now the data is retrieved by the controller through our model, but nothing is displayed yet. The next thing to do is passing this data to the views.</p>
+
+<pre>
+function index()
+{
+	$data['news'] = $this->news_model->get_news();
+	$data['title'] = 'News archive';
+
+	$this->load->view('templates/header', $data);
+	$this->load->view('news/index', $data);
+	$this->load->view('templates/footer');
+
+}
+</pre>
+
+<p>The code above gets all news records from the model and assigns it to a variable. The value for the title is also assigned to the <var>$data['title']</var> element and all data is passed to the views. You now need to create a view to render the news items. Create <dfn>application/views/news/index.php</dfn> and add the next piece of code.</p>
+
+<pre>
+&lt;?php foreach ($news as $news_item): ?&gt;
+
+    &lt;h2&gt;&lt;?php echo $news_item['title'] ?&gt;&lt;/h2&gt;
+    &lt;div id="main"&gt;
+        &lt;?php echo $news_item['text'] ?&gt;
+    &lt;/div&gt;
+    &lt;p&gt;&lt;a href="news/&lt;?php echo $news_item['slug'] ?&gt;"&gt;View article&lt;/a&gt;&lt;/p&gt;
+
+&lt;?php endforeach ?&gt;
+</pre>
+
+<p>Here, each news item is looped and displayed to the user. You can see we wrote our template in PHP mixed with HTML. If you prefer to use a template language, you can use CodeIgniter's <a href="../libraries/parser.html">Template Parser</a> class or a third party parser.</p>
+
+<p>The news overview page is now done, but a page to display individual news items is still absent. The model created earlier is made in such way that it can easily be used for this functionality. You only need to add some code to the controller and create a new view. Go back to the news controller and add the following lines to the file.</p>
+
+<pre>
+function view($slug)
+{
+	$data['news_item'] = $this->news_model->get_news($slug);
+
+	if (empty($data['news_item']))
+	{
+		show_404();
+	}
+
+	$data['title'] = $data['news_item']['title'];
+
+	$this->load->view('templates/header', $data);
+	$this->load->view('news/view', $data);
+	$this->load->view('templates/footer');
+
+}
+</pre>
+
+<p>Instead of calling the <var>get_news()</var> method without a parameter, the <var>$slug</var> variable is passed, so it will return the specific news item. The only things left to do is create the corresponding view at <dfn>application/views/news/view.php</dfn>. Put the following code in this file.</p>
+
+<pre>
+&lt;?php
+echo '&lt;h2&gt;' . $news_item['title'] . '&lt;/h2&gt;';
+echo $news_item['text'];
+</pre>
+
+<h2>Routing</h2>
+<p>Because of the wildcard routing rule created earlier, you need need an extra route to view the controller that you just made. Modify your routing file (<dfn>application/config/routes.php</dfn>) so it looks as follows. This makes sure the requests reaches the news controller instead of going directly to the pages controller. The first line routes URI's with a slug to the view method in the news controller.</p>
+
+<pre>
+$route['news/(:any)'] = 'news/view/$1';
+$route['news'] = 'news';
+$route['(:any)'] = 'pages/view/$1';
+$route['default_controller'] = 'pages/view';
+</pre>
+
+<p>Point your browser to your document root, followed by <dfn>index.php/news</dfn> and watch your news page.</p>

+<h1>Tutorial &minus; Static pages</h1>
+
+<p class="important"><strong>Note:</strong> This tutorial assumes you've downloaded CodeIgniter and <a href="../installation/index.html">installed the framework</a> in your development environment.</p>
+
+<p>The first thing you're going to do is set up a <strong>controller</strong> to handle static pages.
+A controller is simply a class that helps delegate work. It is the glue of your
+web application.</p>
+
+<p>For example, when a call is made to: <code>http://example.com/news/latest/10</code> We might imagine
+that there is a controller named &quot;news&quot;. The method being called on news
+would be &quot;latest&quot;. The news method's job could be to grab 10
+news items, and render them on the page. Very often in MVC, you'll see URL
+patterns that match: <code>http://example.com/[controller-class]/[controller-method]/[arguments]</code>
+As URL schemes become more complex, this may change. But for now, this is all we will need to know.</p>
+
+<p>Create a file at <dfn>application/controllers/pages.php</dfn> with the following code.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="10">
+&lt;?php
+
+class Pages extends CI_Controller {
+
+	function view($page = 'home')
+	{
+
+	}
+}
+</textarea>
+
+<p>You have created a class named &quot;pages&quot;, with a view method that accepts one argument named <var>$page</var>.
+The pages class is extending the CI_Controller class.
+This means that the new pages class can access the methods and variables defined in the CI_Controller class
+(<dfn>system/core/Controller.php</dfn>).</p>
+
+<p>The <strong>controller is what will become the center of every request</strong> to your web application.
+In very technical CodeIgniter discussions, it may be referred to as the <em>super object</em>.
+Like any php class, you refer to it within your controllers as <var>$this</var>.
+Referring to <var>$this</var> is how you will load libraries, views, and generally
+command the framework.</p>
+
+<p>Now you've created your first method, it's time to make some basic page templates.
+We will be creating two &quot;views&quot; (page templates) that act as our page footer and header.</p>
+
+<p>Create the header at <dfn>application/views/templates/header.php</dfn> and add the following code.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="8">
+<html>
+<head>
+	<title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
+</head>
+<body>
+	<h1>CodeIgniter 2 Tutorial</h1>
+	
+</textarea>
+
+<p>The header contains the basic HTML code that you'll want to display before loading the main view, together with a heading. 
+It will also output the <var>$title</var> variable, which we'll define later in the controller.
+Now create a footer at <dfn>application/views/templates/footer.php</dfn> that includes the following code:</p>
+	
+<textarea class="textarea" style="width:100%" cols="50" rows="4">
+<strong>&#38;copy; 2011</strong>	
+</body>
+</html>
+</textarea>
+
+<h2>Adding logic to the controller</h2>
+
+<p>Earlier you set up a controller with a view() method. The method accepts one parameter, which is the name of the page to be loaded.
+The static page templates will be located in the <dfn>application/views/pages/</dfn> directory.</p>
+
+<p>In that directory, create two files named <dfn>home.php</dfn> and <dfn>about.php</dfn>. 
+Within those files, type some text &minus; anything you'd like &minus; and save them. 
+If you like to be particularly un-original, try &quot;Hello World!&quot;.</p>
+
+<p>In order to load those pages, you'll have to check whether the requested page actually exists:</p>
+
+<pre>
+function view($page = 'home')
+{
+			
+	if ( ! file_exists('application/views/pages/' . $page . EXT))
+	{
+		// Whoops, we don't have a page for that!
+		show_404();
+	}
+	
+	$data['title'] = ucfirst($page); // Capitalize the first letter
+	
+	$this->load->view('templates/header', $data);
+	$this->load->view('pages/' . $page, $data);
+	$this->load->view('templates/footer', $data);
+	
+}	
+</pre>
+
+<p>Now, when the page does exist, it is loaded, including the header and footer, and displayed to the user. If the page doesn't exist, a "404 Page not found" error is shown.</p>
+
+<p>The first line in this method checks whether the page actually exists. PHP's native <var>file_exists()</var> function is used to check whether the file is where it's expected to be. <var>show_404()</var> is a built-in CodeIgniter function that renders the default error page.</p>
+
+<p>In the header template, the <var>$title</var> variable was used to customize the page title. The value of title is defined in this method, but instead of assigning the value to a variable, it is assigned to the title element in the <var>$data</var> array.</p>
+
+<p>The last thing that has to be done is loading the views in the order they should be displayed.
+The second parameter in the <var>view()</var> method is used to pass values to the view. Each value in the <var>$data</var> array is assigned to a variable with the name of its key. So the value of <var>$data['title']</var> in the controller is equivalent to $title in the view.<p>
+	
+<h2>Routing</h2>
+
+<p>The controller is now functioning! Point your browser to <dfn>[your-site-url]index.php/pages/view</dfn> to see your page. When you visit <dfn>index.php/pages/view/about</dfn> you'll see the about page, again including the header and footer.</p>
+
+<p>Using custom routing rules, you have the power to map any URI to any controller and method, and break free from the normal convention:
+<code>http://example.com/[controller-class]/[controller-method]/[arguments]</code></p>
+
+<p>Let's do that. Open the routing file located at <dfn>application/config/routes.php</dfn> and add the following two lines. Remove all other code that sets any element in the <var>$route</var> array.</p>
+	
+<pre>
+$route['default_controller'] = 'pages';
+$route['(:any)'] = 'pages/view/$1';
+</pre>
+
+<p>CodeIgniter reads its routing rules from top to bottom and routes the request to the first matching rule. Each rule is a regular expression
+(left-side) mapped to a controller and method name separated by slashes (right-side).
+When a request comes in, CodeIgniter looks for the first match, and calls the appropriate controller and method, possibly with arguments.</p>
+
+<p>More information about routing can be found in the URI Routing <a href="../general/routing.html">documentation</a>.</p>
+
+<p>Here, the second rule in the <var>$routes</var> array matches <strong>any</strong> request using the wildcard string <dfn>(:any)</dfn>.
+and passes the parameter to the view() method of the pages class.</p>
+
+<p>Now visit <dfn>index.php/about</dfn>. Did it get routed correctly to the <var>view()</var> method
+in the pages controller? Awesome!</p>

+# What is CodeIgniter
+
+CodeIgniter is an Application Development Framework - a toolkit - for people who build web sites using PHP. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task.

Subject: Removed some error suppression, which would hide a Notice if the path
 cannot be read. I discovered this by foolishly passing the file_path, not the
 full_path but took forever for me to realise this as the error returned
 (thanks to this error suppression) was "GD is not installed" instead of "File
 cannot be read". Seeing that notice would have made much more sense.

 been first time. Sorry about that one, had to manually separate 2.0.3 changes

+<h1>Tutorial &minus; Introduction</h1>
+
+<p>This tutorial is intended to introduce you to the CodeIgniter framework and the basic principles of MVC architecture. It will show you how a basic CodeIgniter application is constructed in step-by-step fashion.</p> 
+
+<p>In this tutorial, you will be creating a <strong>basic news application</strong>. You will begin by writing the code that can load static pages. Next, you will create a news section that reads news items from a database. Finally, you'll add a form to create news items in the database.</p>
+
+<p>This tutorial will primarily focus on:</p>
+<ul>
+<li>Model-View-Controller basics</li>
+<li>Routing basics</li>
+<li>Form validation</li>
+<li>Performing basic database queries using &quot;Active Record&quot;</li>
+</ul>
+
+<p>The entire tutorial is split up over several pages, each explaining a small part of the functionality of the CodeIgniter framework. You'll go through the following pages:</p>
+<ul>
+<li>Introduction, this page, which gives you an overview of what to expect.</li>
+<li><a href="static_pages.html">Static pages</a>, which will teach you the basics of controllers, views and routing.</li>
+<li><a href="news_section.html">News section</a>, where you'll start using models and will be doing some basic database operations.</li>
+<li><a href="create_news_items.html">Create news items</a>, which will introduce more advanced database operations and form validation.</li>
+<li><a href="conclusion.html">Conclusion</a>, which will give you some pointers on further reading and other resources.</li>
+</ul>
+
+<p>Enjoy your exploration of the CodeIgniter framework.</p>

-<h1>Tutorial &minus; Introduction</h1>
-
-<p>This tutorial is intended to introduce you to the CodeIgniter framework and the basic principles of MVC architecture. It will show you how a basic CodeIgniter application is constructed in step-by-step fashion.</p> 
-
-<p>In this tutorial, you will be creating a <strong>basic news application</strong>. You will begin by writing the code that can load static pages. Next, you will create a news section that reads news items from a database. Finally, you'll add a form to create news items in the database.</p>
-
-<p>This tutorial will primarily focus on:</p>
-<ul>
-<li>Model-View-Controller basics</li>
-<li>Routing basics</li>
-<li>Form validation</li>
-<li>Performing basic database queries using &quot;Active Record&quot;</li>
-</ul>
-
-<p>The entire tutorial is split up over several pages, each explaining a small part of the functionality of the CodeIgniter framework. You'll go through the following pages:</p>
-<ul>
-<li>Introduction, this page, which gives you an overview of what to expect.</li>
-<li><a href="static_pages.html">Static pages</a>, which will teach you the basics of controllers, views and routing.</li>
-<li><a href="news_section.html">News section</a>, where you'll start using models and will be doing some basic database operations.</li>
-<li><a href="create_news_items.html">Create news items</a>, which will introduce more advanced database operations and form validation.</li>
-<li><a href="conclusion.html">Conclusion</a>, which will give you some pointers on further reading and other resources.</li>
-</ul>
-
-<p>Enjoy your exploration of the CodeIgniter framework.</p>

+# CodeIgniter Unit Tests #
+
+*Do not merge to default until these issues have been addressed*
+
+- Clean up naming conventions
+- Figure out config stuff
+- Figure out database testing
+
+### Introduction:
+
+This is the preliminary CodeIgniter testing documentation. It
+will cover both internal as well as external APIs and the reasoning
+behind their implemenation, where appropriate. As with all CodeIgniter
+documentation, this file should maintain a mostly human readable
+format to facilitate clean api design. [see http://arrenbrecht.ch/testing/]
+
+*First public draft: everything is subject to change*
+
+### Requirements
+
+PHP Unit >= 3.5.6
+
+	pear channel-discover pear.phpunit.de
+	pear install phpunit/PHPUnit
+
+vfsStream
+
+	pear channel-discover pear.php-tools.net
+	pear install pat/vfsStream-alpha
+
+#### Installation of PEAR and PHPUnit on Ubuntu
+
+  Installation on Ubuntu requires a few steps. Depending on your setup you may
+  need to use 'sudo' to install these. Mileage may vary but these steps are a
+  good start.
+
+	# Install the PEAR package
+	sudo apt-get install php-pear
+
+	# Add a few sources to PEAR
+	pear channel-discover pear.phpunit.de
+	pear channel-discover pear.symfony-project.com
+	pear channel-discover components.ez.no
+	pear channel-discover pear.symfony-project.com
+
+	# Finally install PHPUnit and vfsStream (including dependencies)
+	pear install --alldeps phpunit/PHPUnit
+	pear install --alldeps pat/vfsStream-alpha
+
+	# Finally, run 'phpunit' from within the ./tests directory
+	# and you should be on your way!
+
+## Test Suites:
+
+CodeIgniter bootstraps a request very directly, with very flat class
+hierarchy. As a result, there is no main CodeIgniter class until the
+controller is instantiated.
+
+This has forced the core classes to be relatively decoupled, which is
+a good thing. However, it makes that portion of code relatively hard
+to test.
+
+Right now that means we'll probably have two core test suites, along
+with a base for application and package tests. That gives us:
+
+1. Bootstrap Test	- test common.php and sanity check codeigniter.php [in planning]
+2. System Test		- test core components in relative isolation [in development]
+3. Application Test	- bootstrapping for application/tests [not started]
+4. Package Test		- bootstrapping for <package>/tests [not started]
+
+### CI_TestCase Documentation
+
+Test cases should extend CI_TestCase. This internally extends
+PHPUnit\_Framework\_TestCase, so you have access to all of your
+usual PHPUnit methods.
+
+We need to provide a simple way to modify the globals and the
+common function output. We also need to be able to mock up
+the super object as we please.
+
+Current API is *not stable*. Names and implementations will change.
+
+    $this->ci_set_config($key, $val)
+
+Set the global config variables. If key is an array, it will
+replace the entire config array. They are _not_ merged.
+
+    $this->ci_instance($obj)
+
+Set the object to use as the "super object", in a lot
+of cases this will be a simple stdClass with the attributes
+you need it to have. If no parameter, will return the instance.
+
+	$this->ci_instance_var($name, $val)
+
+Add an attribute to the super object. This is useful if you
+set up a simple instance in setUp and then need to add different
+class mockups to your super object.
+
+	$this->ci_core_class($name)
+
+Get the _class name_ of a core class, so that you can instantiate
+it. The variable is returned by reference and is tied to the correct
+$GLOBALS key. For example:
+    
+	$cfg =& $this->ci_core_class('cfg'); // returns 'CI_Config'
+    $cfg = new $cfg; // instantiates config and overwrites the CFG global
+
+	$this->ci_set_core_class($name, $obj)
+	
+An alternative way to set one of the core globals.
+
+	$this->ci_get_config()  __internal__
+	
+Returns the global config array. Internal as you shouldn't need to
+call this (you're setting it, after all). Used internally to make
+CI's get_config() work.
+
+	CI_TestCase::instance()  __internal__
+
+Returns an instance of the current test case. We force phpunit to
+run with backup-globals enabled, so this will always be the instance
+of the currently running test class.
+
+### Going forward
+
+#### 1. Bootstrap Test
+
+Testing common.php should be pretty simple. Include the file, and test the
+functions. May require some tweaking so that we can grab the statics from all
+methods (see is_loaded()). Testing the actual CodeIgniter.php file will most
+likely be an output test for the default view, with some object checking after
+the file runs. Needs consideration.
+
+#### 2. System Test
+
+Testing the core system relies on being able to isolate the core components
+as much as possible. A few of them access other core classes as globals. These
+should be mocked up and easy to manipulate.
+
+All functions in common.php should be a minimal implementation, or and mapped
+to a method in the test's parent class to gives us full control of their output.
+
+#### 3. Application Test:
+
+Not sure yet, needs to handle:
+
+- Libraries
+- Helpers
+- Models
+- MY_* files
+- Controllers (uh...?)
+- Views? (watir, selenium, cucumber?)
+- Database Testing
+
+#### 4. Package Test:
+
+I don't have a clue how this will work.
+
+Needs to be able to handle packages
+that are used multiple times within the application (i.e. EE/Pyro modules)
+as well as packages that are used by multiple applications (library distributions)

-$this->ci_core_class($name)
-	Get the _class name_ of a core class, so that you can instantiate
-	it. The variable is returned by reference and is tied to the correct
-	$GLOBALS key. For example:
-	$cfg =& $this->ci_core_class('cfg'); // returns 'CI_Config'
-	$cfg = new $cfg;					// instantiates config and overwrites the CFG global
-
-$this->ci_set_core_class($name, $obj)
-	An alternative way to set one of the core globals.
-
-$this->ci_get_config()  __internal__
-	Returns the global config array. Internal as you shouldn't need to
-	call this (you're setting it, after all). Used internally to make
-	CI's get_config() work.
-
-CI_TestCase::instance()  __internal__
-	Returns an instance of the current test case. We force phpunit to
-	run with backup-globals enabled, so this will always be the instance
-	of the currently running test class.
-
-## 3. Application Test:
-
-Not sure yet, needs to handle:
-- Libraries
-- Helpers
-- Models
-- MY_* files
-- Controllers (uh...?)
-- Views? (watir, selenium, cucumber?)
-
-- Database Testing
-
-
-## 4. Package Test:
-
-I don't have a clue how this will work.
-
-Needs to be able to handle packages
-that are used multiple times within the application (i.e. EE/Pyro modules)
-as well as packages that are used by multiple applications (library distributions)

 field types without constraints. It now uses a less expecting regex and
 defaults to NULL.

+/**
+ * Session Class
+ *
+ * The user interface defined by EllisLabs, now with puggable drivers to manage different storage mechanisms.
+ * By default, the Native PHP session driver will load, but the 'sess_driver' config/param item (see above) can be
+ * used to specify the 'Cookie' driver, or any other you might create.
+ * Once loaded, this driver setup is a drop-in replacement for the former CI_Session library, taking its place as the
+ * 'session' member of the global controller framework (e.g.: $CI->session or $this->session).
+ * In keeping with the CI_Driver methodology, multiple drivers may be loaded, although this might be a bit confusing.
+ * The Session library class keeps track of the most recently loaded driver as "current" to call for driver methods.
+ * Ideally, one driver is loaded and all calls go directly through the main library interface. However, any methods
+ * called through the specific driver will switch the "current" driver to itself before invoking the library method
+ * (which will then call back into the driver for low-level operations). So, alternation between two drivers can be
+ * achieved by specifying which driver to use for each call (e.g.: $this->session->native->set_userdata('foo', 'bar');
+ * $this->session->cookie->userdata('foo'); $this->session->native->unset_userdata('foo');). Notice in the previous
+ * example that the _native_ userdata value 'foo' would be set to 'bar', which would NOT be returned by the call for
+ * the _cookie_ userdata 'foo', nor would the _cookie_ value be unset by the call to unset the _native_ 'foo' value.

+ * SessionDriver Class
+ *
+ * Extend this class to make a new Session driver.
+ * A Session driver basically manages an array of name/value pairs with some sort of storage mechanism.
+ * To make a new driver, derive from (extend) SessionDriver. Overload the initialize method and read or create
+ * session data. Then implement a save handler to write changed data to storage (sess_save), a destroy handler
+ * to remove deleted data (sess_destroy), and an access handler to expose the data (get_userdata).
+ * Put your driver in the libraries/Session/drivers folder anywhere in the loader paths. This includes the application
+ * directory, the system directory, or any path you add with $CI->load->add_package_path().
+ * Your driver must be named Session_<name>, where <name> is capitalized, and your filename must be Session_<name>.EXT,
+ * preferably also capitalized. (e.g.: Session_Foo in libraries/Session/drivers/Session_Foo.php)
+ * Then specify the driver by setting 'sess_driver' in your config file or as a parameter when loading the Session
+ * object. (e.g.: $config['sess_driver'] = 'foo'; OR $CI->load->driver('session', array('sess_driver' => 'foo')); )
+ * Already provided are the Native driver, which manages the native PHP $_SESSION array, and
+ * the Cookie driver, which manages the data in a browser cookie, with optional extra storage in a database table.

 <h1>Active Record Caching</h1>
 
 <p>While not &quot;true&quot; caching, Active Record enables you to save (or &quot;cache&quot;) certain parts of your queries for reuse at a later point in your script's execution. Normally, when an Active Record call is completed, all stored information is reset for the next call. With caching, you can prevent this reset, and reuse information easily.</p>

If an empty string was passed, the typecast was changing it to 0. This
produced "LIMIT 0" which returned no results. This must be a bug and not
a feature because there are other params after limit in both
$this->db->limit and $this->db->get.

 CodeIgniter is an Application Development Framework - a toolkit - for people who build web sites using PHP. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task.
 
+# Release Information
+
+CodeIgniter 2.1.0 Dev
+
+THIS RELASE IS A DEVELOPMENT REALEASE AND NOT INTENDED FOR PRODUCTION USE.
+PLASE USE AT YOUR OWN RISK
+
+# Changelog and New Feature
+
+You can find it on [user_guide/changelog.html](https://github.com/EllisLab/CodeIgniter/blob/develop/user_guide/changelog.html)
+
+# Server Requirements
+
+* PHP version 5.1.6 or newer.
+* A Database is required for most web application programming. Current supported databases are MySQL (4.1+), MySQLi, MS SQL, Postgres, Oracle, SQLite, ODBC and CUBRID.
+
+# Installation 
+
+Please see file on [CodeIgniter User Guide](http://codeigniter.com/user_guide/installation/index.html)
+
+# Contributing
+
+CodeIgniter is a community driven project and accepts contributions of code and documentation from the community. These contributions are made in the form of Issues or Pull Requests on the EllisLab CodeIgniter repository on GitHub.
+
+Issues are a quick way to point out a bug. If you find a bug or documentation error in CodeIgniter then please check a few things first:
+
+     
+    There is not already an open Issue
+     
+    The issue has already been fixed (check the develop branch, or look for closed Issues)
+     
+    Is it something really obvious that you fix it yourself?
+
+Reporting issues is helpful but an even better approach is to send a Pull Request, which is done by “Forking� the main repository and committing to your own copy. This will require you to use the version control system called Git.
+Guidelines
+
+Before we look into how, here are the guidelines. If your Pull Requests fail to pass these guidelines it will be declined and you will need to re-submit when you’ve made the changes. This might sound a bit tough, but it is required for us to maintain quality of the code-base.
+
+PHP Style: All code must meet the Style Guide, which is essentially the Allman indent style, underscores and readable operators. This makes certain that all code is the same format as the existing code and means it will be as readable as possible.
+
+Documentation: If you change anything that requires a change to documentation then you will need to add it. New classes, methods, parameters, changing default values, etc are all things that will require a change to documentation. The change-log must also be updated for every change. Also PHPDoc blocks must be maintained.
+
+Compatibility: CodeIgniter is compatible with PHP 5.1.6 so all code supplied must stick to this requirement. If PHP 5.2 or 5.3 functions or features are used then there must be a fallback for PHP 5.1.6.
+
+Branching: CodeIgniter uses the Git-Flow branching model which requires all pull requests to be sent to the “develop� branch. This is where the next planned version will be developed. The “master� branch will always contain the latest stable version and is kept clean so a “hotfix� (e.g: an emergency security patch) can be applied to master to create a new version, without worrying about other features holding it up. For this reason all commits need to be made to “develop� and any sent to “master� will be closed automatically. If you have multiple changes to submit, please place all changes into their own branch on your fork.
+
+One thing at a time: A pull request should only contain one change. That does not mean only one commit, but one change - however many commits it took. The reason for this is that if you change X and Y but send a pull request for both at the same time, we might really want X but disagree with Y, meaning we cannot merge the request. Using the Git-Flow branching model you can create new branches for both of these features and send two requests.
+How-to Guide
+
+There are two ways to make changes, the easy way and the hard way. Either way you will need to create a GitHub account.
+Easy way
+
+GitHub allows in-line editing of files for making simple typo changes and quick-fixes. This is not the best way as you are unable to test the code works. If you do this you could be introducing syntax errors, etc, but for a Git-phobic user this is good for a quick-fix.
+Hard way
+
+The best way to contribute is to “clone� your fork of CodeIgniter to your development area. That sounds like some jargon, but “forking� on GitHub means “making a copy of that repo to your account� and “cloning� means “copying that code to your environment so you can work on it�.
+
+    Set up Git (Windows, Mac & Linux)
+    Go to the CodeIgniter repo
+    Fork it
+    Clone your CodeIgniter repo: git@github.com:<your-name>/CodeIgniter.git
+    Checkout the “develop� branch At this point you are ready to start making changes. Fix existing bugs on the Issue tracker after taking a look to see nobody else is working on them.
+    Commit the files
+    Push your develop branch to your fork
+    Send a pull request http://help.github.com/send-pull-requests/
+
+The Reactor Engineers will now be alerted about the change and at least one of the team will respond. If your change fails to meet the guidelines it will be bounced, or feedback will be provided to help you improve it.
+
+Once the Reactor Engineer handling your pull request is happy with it they will post it to the internal EllisLab discussion area to be double checked by the other Engineers and EllisLab developers. If nobody has a problem with the change then it will be merged into develop and will be part of the next release.
+Keeping your fork up-to-date
+
+Unlike systems like Subversion, Git can have multiple remotes. A remote is the name for a URL of a Git repository. By default your fork will have a remote named “origin� which points to your fork, but you can add another remote named “codeigniter� which points to git://github.com/EllisLab/CodeIgniter.git. This is a read-only remote but you can pull from this develop branch to update your own.
+
+If you are using command-line you can do the following:
+
+    git remote add codeigniter git://github.com/EllisLab/CodeIgniter.git
+
+    git pull codeigniter develop
+
+    git push origin develop
+
+Now your fork is up to date. This should be done regularly, or before you send a pull request at least.

-PHP Style: All code must meet the Style Guide, which is essentially the Allman indent style, underscores and readable operators. This makes certain that all code is the same format as the existing code and means it will be as readable as possible.
+PHP Style: All code must meet the [Style Guide](http://codeigniter.com/user_guide/general/styleguide.html), which is essentially the [Allman indent style](http://en.wikipedia.org/wiki/Indent_style#Allman_style), underscores and readable operators. This makes certain that all code is the same format as the existing code and means it will be as readable as possible.
 
 Documentation: If you change anything that requires a change to documentation then you will need to add it. New classes, methods, parameters, changing default values, etc are all things that will require a change to documentation. The change-log must also be updated for every change. Also PHPDoc blocks must be maintained.
 
 Compatibility: CodeIgniter is compatible with PHP 5.1.6 so all code supplied must stick to this requirement. If PHP 5.2 or 5.3 functions or features are used then there must be a fallback for PHP 5.1.6.
 
-Branching: CodeIgniter uses the Git-Flow branching model which requires all pull requests to be sent to the “develop� branch. This is where the next planned version will be developed. The “master� branch will always contain the latest stable version and is kept clean so a “hotfix� (e.g: an emergency security patch) can be applied to master to create a new version, without worrying about other features holding it up. For this reason all commits need to be made to “develop� and any sent to “master� will be closed automatically. If you have multiple changes to submit, please place all changes into their own branch on your fork.

If you have multiple changes to submit, please place all changes into their own branch on your fork.
 
 One thing at a time: A pull request should only contain one change. That does not mean only one commit, but one change - however many commits it took. The reason for this is that if you change X and Y but send a pull request for both at the same time, we might really want X but disagree with Y, meaning we cannot merge the request. Using the Git-Flow branching model you can create new branches for both of these features and send two requests.
 How-to Guide

-There are two ways to make changes, the easy way and the hard way. Either way you will need to create a GitHub account.
 Easy way
-
 GitHub allows in-line editing of files for making simple typo changes and quick-fixes. This is not the best way as you are unable to test the code works. If you do this you could be introducing syntax errors, etc, but for a Git-phobic user this is good for a quick-fix.
-Hard way
 
+Hard way
 The best way to contribute is to “clone� your fork of CodeIgniter to your development area. That sounds like some jargon, but “forking� on GitHub means “making a copy of that repo to your account� and “cloning� means “copying that code to your environment so you can work on it�.
 
     Set up Git (Windows, Mac & Linux)
     Go to the CodeIgniter repo
     Fork it
     Clone your CodeIgniter repo: git@github.com:<your-name>/CodeIgniter.git
-    Checkout the “develop� branch At this point you are ready to start making changes. Fix existing bugs on the Issue tracker after taking a look to see nobody else is working on them.

 CodeIgniter is an Application Development Framework - a toolkit - for people who build web sites using PHP. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task.

-<h2>Version 2.0.3</h2>
-<p>Release Date: August 20, 2011</p>
-
-<ul>
-	<li>Security
-		<ul>
-			<li>An improvement was made to the MySQL and MySQLi drivers to prevent exposing a potential vector for SQL injection on sites using multi-byte character sets in the database client connection.  <p>An incompatibility in PHP versions &lt; 5.2.3 and MySQL &lt; 5.0.7 with <em>mysql_set_charset()</em> creates a situation where using multi-byte  character sets on these environments may potentially expose a SQL injection attack vector.  Latin-1, UTF-8, and other "low ASCII" character sets are unaffected on all environments.</p>  <p class="critical">If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable.</p></li>

-<h1>Active Record Class</h1>
-
-<p>CodeIgniter uses a modified version of the Active Record Database Pattern.
-This pattern allows information to be retrieved, inserted, and updated in your database with minimal scripting.
-In some cases only one or two lines of code are necessary to perform a database action.
-CodeIgniter does not require that each database table be its own class file.  It instead provides a more simplified interface.</p>
-
-<p>Beyond simplicity, a major benefit to using the Active Record features is that it allows you to create database independent applications, since the query syntax
-is generated by each database adapter.  It also allows for safer queries, since the values are escaped automatically by the system.</p>
-
-<p class="important"><strong>Note:</strong>  If you intend to write your own queries you can disable this class in your database config file, allowing the core database library and adapter to utilize fewer resources.<br /></p>

-
-<h1><a name="select">&nbsp;</a>Selecting Data</h1>
-
-<p>The following functions allow you to build SQL <strong>SELECT</strong> statements.</p>
-
-<h2>$this->db->get();</h2>
-
-<p>Runs the selection query and returns the result.  Can be used by itself to retrieve all records from a table:</p>
-
-<code>$query = $this->db->get('mytable');<br />
-<br />
-// Produces: SELECT * FROM mytable</code>
-
-<p>The second and third parameters enable you to set a limit and offset clause:</p>
-
-<code>$query = $this->db->get('mytable', 10, 20);<br />
-<br />
-// Produces: SELECT * FROM mytable LIMIT 20, 10 (in MySQL. Other databases have slightly different syntax)</code>
-
-<p>You'll notice that the above function is assigned to a variable named <kbd>$query</kbd>, which can be used to show the results:</p>
-
-<code>$query = $this->db->get('mytable');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-}</code>
-
-<p>Please visit the <a href="results.html">result functions</a> page for a full discussion regarding result generation.</p>
-
-
-<h2>$this->db->get_where();</h2>
-
-<p>Identical to the above function except that it permits you to add a "where" clause in the second parameter,
-instead of using the db->where() function:</p>
-
-<code>$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);</code>
-
-<p>Please read the about the where function below for more information.</p>
-<p class="important">Note: get_where() was formerly known as getwhere(), which has been removed</p>
-
-<h2>$this->db->select();</h2>
-<p>Permits you to write the SELECT portion of your query:</p>
-<p><code>
-$this->db->select('title, content, date');<br />
-<br />
-$query = $this->db->get('mytable');<br />
-<br />
-// Produces: SELECT title, content, date FROM mytable</code></p>
-<p class="important"><strong>Note:</strong> If you are selecting all (*) from a table you do not need to use this function.  When omitted, CodeIgniter assumes you wish to SELECT *</p>
-
-<p>$this-&gt;db-&gt;select() accepts an optional second parameter. If you set it to FALSE, CodeIgniter will not try to protect your field or table names with backticks. This is useful if you need a compound select statement.</p>
-<p><code>$this-&gt;db-&gt;select('(SELECT SUM(payments.amount) FROM payments WHERE payments.invoice_id=4') AS amount_paid', FALSE); <br />
-$query = $this-&gt;db-&gt;get('mytable');<br />
-</code></p>
-<h2>$this->db->select_max();</h2>
-<p>Writes a "SELECT MAX(field)" portion for your query. You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_max('age');<br />
-$query = $this->db->get('members');<br />
-
-// Produces: SELECT MAX(age) as age FROM members<br />
-<br />
-$this-&gt;db-&gt;select_max('age', 'member_age');<br />
-$query = $this-&gt;db-&gt;get('members');<br />
-// Produces: SELECT MAX(age) as member_age FROM members</code></p>
-
-<h2>$this->db->select_min();</h2>
-<p>Writes a "SELECT MIN(field)" portion for your query. As with <dfn>select_max()</dfn>, You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_min('age');<br />
-$query = $this->db->get('members');<br />
-// Produces: SELECT MIN(age) as age FROM members</code></p>
-
-<h2>$this->db->select_avg();</h2>
-<p>Writes a "SELECT AVG(field)" portion for your query. As with <dfn>select_max()</dfn>, You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_avg('age');<br />
-$query = $this->db->get('members');<br />
-// Produces: SELECT AVG(age) as age FROM members</code></p>
-
-<h2>$this->db->select_sum();</h2>
-<p>Writes a "SELECT SUM(field)" portion for your query. As with <dfn>select_max()</dfn>, You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_sum('age');<br />
-$query = $this->db->get('members');<br />
-// Produces: SELECT SUM(age) as age FROM members</code></p>
-
-<h2>$this->db->from();</h2>
-
-<p>Permits you to write the FROM portion of your query:</p>
-
-<code>
-$this->db->select('title, content, date');<br />
-$this->db->from('mytable');<br />
-<br />
-$query = $this->db->get();<br />
-<br />
-// Produces: SELECT title, content, date FROM mytable</code>
-
-<p class="important">Note: As shown earlier, the FROM portion of your query can be specified in the <dfn>$this->db->get()</dfn> function, so use whichever method
-you prefer.</p>
-
-<h2>$this->db->join();</h2>
-
-<p>Permits you to write the JOIN portion of your query:</p>
-
-<code>
-$this->db->select('*');<br />
-$this->db->from('blogs');<br />
-$this->db->join('comments', 'comments.id = blogs.id');<br />
-<br />
-$query = $this->db->get();<br />
-<br />
-// Produces: <br />
-// SELECT * FROM blogs<br />
-// JOIN comments ON comments.id = blogs.id<br />
-</code>
-
-<p>Multiple function calls can be made if you need several joins in one query.</p>
-
-<p>If you need a specific type of JOIN you can specify it via the third parameter of the function.
-Options are: left, right, outer, inner, left outer, and right outer.</p>
-
-<code>
-$this->db->join('comments', 'comments.id = blogs.id', <strong>'left'</strong>);<br />
-<br />
-// Produces: LEFT JOIN comments ON comments.id = blogs.id</code>
-
-
-
-
-
-<h2>$this->db->where();</h2>
-<p>This function enables you to set <strong>WHERE</strong> clauses using one of four methods:</p>
-
-<p class="important"><strong>Note:</strong> All values passed to this function are escaped automatically, producing safer queries.</p>
-
-<ol>
-	<li><strong>Simple key/value method:</strong>
-
-	<code>$this->db->where('name', $name);
-	<br /><br />// Produces: WHERE name = 'Joe'	</code>
-
-	<p>Notice that the equal sign is added for you.</p>
-
-	<p>If you use multiple function calls they will be chained together with <var>AND</var> between them:</p>
-
-	<code>$this->db->where('name', $name);<br />
-	$this->db->where('title', $title);<br />
-	$this->db->where('status', $status);
-	<br /><br />// WHERE name = 'Joe' AND title = 'boss' AND status = 'active'	</code>	</li>
-
-	<li><strong>Custom key/value method:</strong>
-
-	<p>You can include an operator in the first parameter in order to control the comparison:</p>
-
-	<code>$this->db->where('name !=', $name);<br />
-	$this->db->where('id <', $id);
-	<br /><br />// Produces: WHERE name != 'Joe' AND id < 45	</code>	</li>
-	<li><strong>Associative array method:</strong>
-
-
-	<code>
-	$array = array('name' => $name, 'title' => $title, 'status' => $status);<br /><br />
-
-	$this->db->where($array);
-	<br /><br />// Produces: WHERE name = 'Joe' AND title = 'boss' AND status = 'active'	</code>
-
-	<p>You can include your own operators using this method as well:</p>
-
-	<code>
-	$array = array('name !=' => $name, 'id <' => $id, 'date >' => $date);<br /><br />
-
-	$this->db->where($array);</code>	</li>
-		<li><strong>Custom string:</strong>
-
-		<p>You can write your own clauses manually:</p>
-
-		<code>
-		$where = "name='Joe' AND status='boss' OR status='active'";<br /><br />
-		$this->db->where($where);</code></li>
-	</ol>
-
-
-<p>$this-&gt;db-&gt;where() accepts an optional third parameter. If you set it to FALSE, CodeIgniter will not try to protect your field or table names with backticks.</p>
-<p><code>		$this-&gt;db-&gt;where('MATCH (field) AGAINST (&quot;value&quot;)', NULL, FALSE);<br />
-</code></p>
-<h2>$this->db->or_where();</h2>
-<p>This function is identical to the one above, except that multiple instances are joined by OR:</p>
-
-<code>
-$this->db->where('name !=', $name);<br />
-$this->db->or_where('id >', $id);
-<br />
-<br />// Produces: WHERE name != 'Joe' OR id > 50</code>
-
-<p class="important">Note: or_where() was formerly known as orwhere(), which has been removed.</p>
-
-
-<h2>$this->db->where_in();</h2>
-<p>Generates a WHERE field IN ('item', 'item') SQL query joined with  AND if appropriate</p>
-<p><code>
-	$names = array('Frank', 'Todd', 'James');<br />
-	$this->db->where_in('username', $names);<br />
-	// Produces: WHERE username IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->or_where_in();</h2>
-<p>Generates a WHERE field IN ('item', 'item') SQL query joined with OR if appropriate</p>
-<p><code>
-	$names = array('Frank', 'Todd', 'James');<br />
-	$this->db->or_where_in('username', $names);<br />
-	// Produces: OR username IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->where_not_in();</h2>
-<p>Generates a WHERE field NOT IN ('item', 'item') SQL query joined with AND if appropriate</p>
-<p><code>
-	$names = array('Frank', 'Todd', 'James');<br />
-	$this->db->where_not_in('username', $names);<br />
-	// Produces: WHERE username NOT IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->or_where_not_in();</h2>
-<p>Generates a WHERE field NOT IN ('item', 'item') SQL query joined with OR if appropriate</p>
-<p><code>
-	$names = array('Frank', 'Todd', 'James');<br />
-	$this->db->or_where_not_in('username', $names);<br />
-	// Produces: OR username NOT IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->like();</h2>
-<p>This function enables you to generate <strong>LIKE</strong> clauses, useful for doing searches.</p>
-
-<p class="important"><strong>Note:</strong> All values passed to this function are escaped automatically.</p>
-
-
-<ol>
-	<li><strong>Simple key/value method:</strong>
-
-	<code>$this->db->like('title', 'match');
-	<br /><br />// Produces: WHERE title LIKE '%match%'	</code>
-
-	<p>If you use multiple function calls they will be chained together with <var>AND</var> between them:</p>
-
-	<code>$this->db->like('title', 'match');<br />
-	$this->db->like('body', 'match');
-	<br /><br />
-	// WHERE title LIKE '%match%' AND  body LIKE '%match%</code>
-	If you want to control where the wildcard (%) is placed, you can use an optional third argument. Your options are 'before', 'after' and 'both' (which is the default).
-	<code>$this->db->like('title', 'match', 'before');
-	<br />
-		// Produces: WHERE title LIKE '%match'	<br />
-		<br />
-	$this-&gt;db-&gt;like('title', 'match', 'after'); <br />
-// Produces: WHERE title LIKE 'match%' <br />
-<br />
-	$this-&gt;db-&gt;like('title', 'match', 'both'); <br />
-// Produces: WHERE title LIKE '%match%' </code>	</li>
-
-If you do not want to use the wildcard (%) you can pass to the optional third argument the option 'none'.
-
-<code>
-	$this-&gt;db-&gt;like('title', 'match', 'none'); <br />
-// Produces: WHERE title LIKE 'match'
-</code>
-
-	<li><strong>Associative array method:</strong>
-
-	<code>
-	$array = array('title' => $match, 'page1' => $match, 'page2' => $match);<br /><br />
-
-	$this->db->like($array);
-	<br /><br />// WHERE title LIKE '%match%' AND  page1 LIKE '%match%' AND  page2 LIKE '%match%'</code></li>
-	</ol>
-
-
-<h2>$this->db->or_like();</h2>
-<p>This function is identical to the one above, except that multiple instances are joined by OR:</p>
-
-<code>
-$this->db->like('title', 'match');<br />
-$this->db->or_like('body', $match);
-<br />
-<br />// WHERE title LIKE '%match%' OR  body LIKE '%match%'</code>
-
-
-
-
-<p class="important">Note: or_like() was formerly known as orlike(), which has been removed.</p>
-<h2>$this-&gt;db-&gt;not_like();</h2>
-<p>This function is identical to <strong>like()</strong>, except that it generates NOT LIKE statements:</p>
-<code> $this-&gt;db-&gt;not_like('title', 'match');<br />
-<br />
-// WHERE title NOT LIKE '%match%</code>
-<h2>$this-&gt;db-&gt;or_not_like();</h2>
-<p>This function is identical to <strong>not_like()</strong>, except that multiple instances are joined by OR:</p>
-<code> $this-&gt;db-&gt;like('title', 'match');<br />
-$this-&gt;db-&gt;or_not_like('body', 'match'); <br />
-<br />
-// WHERE title  LIKE '%match% OR body NOT LIKE '%match%'</code>
-<h2>$this->db->group_by();</h2>
-<p>Permits you to write the GROUP BY portion of your query:</p>
-
-<code>$this->db->group_by("title");
-<br /><br />// Produces: GROUP BY title
-</code>
-
-<p>You can also pass an array of multiple values as well:</p>
-
-<code>$this->db->group_by(array("title", "date"));
-<br />
-<br />// Produces: GROUP BY title, date</code>
-
-<p class="important">Note: group_by() was formerly known as groupby(), which has been removed. </p>
-
-<h2> $this-&gt;db-&gt;distinct();<br />
-</h2>
-<p>Adds the &quot;DISTINCT&quot; keyword to  a query</p>
-<p><code>$this-&gt;db-&gt;distinct();<br />
-	$this-&gt;db-&gt;get('table');<br />
-		<br />
-	// Produces: SELECT DISTINCT * FROM table</code></p>
-<h2>$this->db->having();</h2>
-<p>Permits you to write the HAVING portion of your query. There are 2 possible syntaxes, 1 argument or 2:</p>
-
-<code>$this->db->having('user_id = 45');
-<br />
-// Produces: HAVING user_id = 45<br />
-<br />
-$this-&gt;db-&gt;having('user_id',  45); <br />
-// Produces: HAVING user_id = 45<br />
-<br />
-</code>
-
-<p>You can also pass an array of multiple values as well:</p>
-
-
-<p><code>$this->db->having(array('title =' => 'My Title', 'id <' => $id)); <br />
-		<br />
-	// Produces: HAVING title = 'My Title', id < 45</code></p>
-<p>If you are using a database that CodeIgniter escapes queries for, you can prevent escaping content by passing an optional third argument, and setting it to FALSE.</p>
-<p><code>$this-&gt;db-&gt;having('user_id',  45); <br />
-// Produces: HAVING `user_id` = 45 in some databases such as MySQL
-		<br />
-		$this-&gt;db-&gt;having('user_id',  45, FALSE); <br />
-// Produces: HAVING user_id = 45</code></p>
-<h2>$this-&gt;db-&gt;or_having();</h2>
-<p>Identical to having(), only separates multiple clauses with &quot;OR&quot;.</p>
-<h2>$this->db->order_by();</h2>
-<p>Lets you set an ORDER BY clause. The first parameter contains the name of the column you would like to order by.
-The second parameter lets you set the direction of the result.  Options are <kbd>asc</kbd> or <kbd>desc</kbd>, or <kbd>random</kbd>. </p>
-
-<code>$this->db->order_by("title", "desc");
-<br />
-<br />// Produces: ORDER BY title DESC
-</code>
-
-<p>You can also pass your own string in the first parameter:</p>
-
-<code>$this->db->order_by('title desc, name asc');
-<br />
-<br />// Produces: ORDER BY title DESC, name ASC
-</code>
-
-<p>Or multiple function calls can be made if you need multiple fields.</p>
-
-<p><code>$this->db->order_by("title", "desc");<br />
-	$this->db->order_by("name", "asc"); <br />
-	<br />
-	// Produces: ORDER BY title DESC, name ASC
-	</code></p>
-<p class="important">Note: order_by() was formerly known as orderby(), which has been removed.</p>
-<p class="important">Note: random ordering is not currently supported in Oracle or MSSQL drivers. These will default to 'ASC'.</p>
-<h2>$this->db->limit();</h2>
-<p>Lets you limit the number of rows you would like returned by the query:</p>
-
-<code>
-$this->db->limit(10);<br />
-<br />
-// Produces: LIMIT 10</code>
-
-
-<p>The second parameter lets you set a result offset.</p>
-
-<code>
-$this->db->limit(10, 20);<br />
-<br />
-// Produces: LIMIT 20, 10 (in MySQL.  Other databases have slightly different syntax)</code>
-
-
-<h2>$this->db->count_all_results();</h2>
-
-<p>Permits you to determine the number of rows in a particular Active Record query. Queries will accept Active Record restrictors such as where(),  or_where(), like(), or_like(), etc. Example:</p>
-<code>echo $this->db->count_all_results('<var>my_table</var>');<br />
-
-// Produces an integer, like 25<br />
-<br />
-$this-&gt;db-&gt;like('title', 'match');<br />
-$this-&gt;db-&gt;from('<var>my_table</var>');<br />
-echo $this-&gt;db-&gt;count_all_results();<br />
-// Produces an integer, like 17 </code>
-
-<h2>$this->db->count_all();</h2>
-
-<p>Permits you to determine the number of rows in a particular table.  Submit the table name in the first parameter. Example:</p>
-
-<code>echo $this->db->count_all('<var>my_table</var>');<br />
-<br />
-// Produces an integer, like 25</code>
-
-
-
-<a name="insert">&nbsp;</a>
-<h1>Inserting Data</h1>
-
-<h2>$this->db->insert();</h2>
-<p>Generates an insert string based on the data you supply, and runs the query. You can either pass an
-<strong>array</strong> or an <strong>object</strong> to the function.  Here is an example using an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
-&nbsp;&nbsp;&nbsp;'name' => 'My Name' ,<br />
-&nbsp;&nbsp;&nbsp;'date' => 'My date'<br />
-);<br />
-<br />
-$this->db->insert('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')</code>
-
-<p>The first parameter will contain the table name, the second is an associative array of values.</p>
-
-<p>Here is an example using an object:</p>
-
-<code>
-/*<br />
-&nbsp;&nbsp;&nbsp;&nbsp;class Myclass {<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $title = 'My Title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $content = 'My Content';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $date = 'My Date';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-*/<br />
-<br />
-$object = new Myclass;<br />
-<br />
-$this->db->insert('mytable', $object);
-<br /><br />
-// Produces: INSERT INTO mytable (title, content, date) VALUES ('My Title', 'My Content', 'My Date')</code>
-
-<p>The first parameter will contain the table name, the second is an object.</p>
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-<h2>$this->db->insert_batch();</h2>
-<p>Generates an insert string based on the data you supply, and runs the query. You can either pass an
-<strong>array</strong> or an <strong>object</strong> to the function.  Here is an example using an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'My Name' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'My date'<br />
-&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'Another title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'Another Name' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'Another date'<br />
-&nbsp;&nbsp;&nbsp;)<br />
-);<br />
-<br />
-$this->db->insert_batch('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'),  ('Another title', 'Another name', 'Another date')</code>
-
-<p>The first parameter will contain the table name, the second is an associative array of values.</p>
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-
-
-<h2>$this->db->set();</h2>
-<p>This function enables you to set values for <dfn>inserts</dfn> or <dfn>updates</dfn>.</p>
-
-<p><strong>It can be used instead of passing a data array directly to the insert or update functions:</strong> </p>
-
-<code>$this->db->set('name', $name);
-<br />
-$this->db->insert('mytable');
-<br /><br />
-// Produces: INSERT INTO mytable (name) VALUES ('{$name}')</code>
-
-<p>If you use multiple function called they will be assembled properly based on whether you are doing an insert or an update:</p>
-
-<code>$this-&gt;db-&gt;set('name', $name);<br />
-$this-&gt;db-&gt;set('title', $title);<br />
-$this-&gt;db-&gt;set('status', $status);<br />
-$this-&gt;db-&gt;insert('mytable'); </code>
-<p><strong>set()</strong> will also accept an optional third parameter ($escape), that will prevent data from being escaped if set to FALSE. To illustrate the difference, here is set() used both with and without the escape parameter.</p>
-<p><code>$this-&gt;db-&gt;set('field', 'field+1', FALSE);<br />
-	$this-&gt;db-&gt;insert('mytable'); <br />

-	$this-&gt;db-&gt;insert('mytable'); <br />
-	// gives INSERT INTO mytable (field) VALUES ('field+1')</code></p>
-<p>You can also pass an associative array to this function:</p>
-<code>
-$array = array('name' => $name, 'title' => $title, 'status' => $status);<br /><br />
-
-$this->db->set($array);<br />
-$this->db->insert('mytable');
-</code>
-
-<p>Or an object:</p>
-
-
-<code>
-/*<br />
-&nbsp;&nbsp;&nbsp;&nbsp;class Myclass {<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $title = 'My Title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $content = 'My Content';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $date = 'My Date';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-*/<br />
-<br />
-$object = new Myclass;<br />
-<br />
-$this->db->set($object);<br />
-$this->db->insert('mytable');
-</code>
-
-
-
-<a name="update">&nbsp;</a>
-<h1>Updating Data</h1>
-
-<h2>$this->db->update();</h2>
-<p>Generates an update string and runs the query based on the data you supply.  You can pass an
-<strong>array</strong> or an <strong>object</strong> to the function. Here is an example using
-an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => $title,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => $name,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => $date<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->db->where('id', $id);<br />
-$this->db->update('mytable', $data);
-<br /><br />
-// Produces:<br />
-// UPDATE mytable <br />
-// SET title = '{$title}', name = '{$name}', date = '{$date}'<br />
-// WHERE id = $id</code>
-
-<p>Or you can supply an object:</p>
-
-<code>
-/*<br />
-&nbsp;&nbsp;&nbsp;&nbsp;class Myclass {<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $title = 'My Title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $content = 'My Content';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $date = 'My Date';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-*/<br />
-<br />
-$object = new Myclass;<br />
-<br />
-$this->db->where('id', $id);<br />
-$this->db->update('mytable', $object);
-<br />
-<br />
-// Produces:<br />
-// UPDATE mytable <br />
-// SET title = '{$title}', name = '{$name}', date = '{$date}'<br />
-// WHERE id = $id</code>
-
-
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-<p>You'll notice the use of the <dfn>$this->db->where()</dfn> function, enabling you to set the WHERE clause.
-You can optionally pass this information directly into the update function as a string:</p>
-
-<code>$this->db->update('mytable', $data, "id = 4");</code>
-
-<p>Or as an array:</p>
-
-<code>$this->db->update('mytable', $data, array('id' => $id));</code>
-
-<p>You may also use the <dfn>$this->db->set()</dfn> function described above when performing updates.</p>
-
-<h2>$this->db->update_batch();</h2>
-<p>Generates an update string based on the data you supply, and runs the query. You can either pass an
-<strong>array</strong> or an <strong>object</strong> to the function.  Here is an example using an array:</p>
-
-<code>
-$data = array(<br/>
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'My Name 2' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'My date 2'<br />
-&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'Another title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'Another Name 2' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'Another date 2'<br />
-&nbsp;&nbsp;&nbsp;)<br/>
-);<br />
-<br />
-$this->db->update_batch('mytable', $data, 'title');
-<br /><br />
-// Produces: <br />
-// UPDATE `mytable` SET `name` = CASE<br />
-// WHEN `title` = 'My title' THEN 'My Name 2'<br />
-// WHEN `title` = 'Another title' THEN 'Another Name 2'<br />
-// ELSE `name` END,<br />
-// `date` = CASE <br />
-// WHEN `title` = 'My title' THEN 'My date 2'<br />
-// WHEN `title` = 'Another title' THEN 'Another date 2'<br />
-// ELSE `date` END<br />
-// WHERE `title` IN ('My title','Another title')</code>
-
-<p>The first parameter will contain the table name, the second is an associative array of values, the third parameter is the where key.</p>
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-
-<a name="delete">&nbsp;</a>
-<h1>Deleting Data</h1>
-
-
-
-<h2>$this->db->delete();</h2>
-<p>Generates a delete SQL string and runs the query.</p>
-
-<code>
-$this->db->delete('mytable', array('id' => $id));
-<br /><br />
-// Produces:<br />
-// DELETE FROM mytable <br />
-// WHERE id = $id</code>
-
-<p>The first parameter is the table name, the second is the where clause. You can also use the <dfn>where()</dfn> or <dfn>or_where()</dfn> functions instead of passing
-the data to the second parameter of the function:</p>
-
-<p><code> $this->db->where('id', $id);<br />
-	$this->db->delete('mytable'); <br />
-	<br />
-	// Produces:<br />
-	// DELETE FROM mytable <br />
-	// WHERE id = $id</code></p>
-<p>An array of table names can be passed into delete() if you would like to delete data from more than 1 table.</p>
-<p><code>$tables = array('table1', 'table2', 'table3');<br />
-$this-&gt;db-&gt;where('id', '5');<br />
-$this-&gt;db-&gt;delete($tables);</code></p>
-<p>If you want to delete all data from a table, you can use the <dfn>truncate()</dfn> function, or <dfn>empty_table()</dfn>.</p>
-<h2>$this-&gt;db-&gt;empty_table();</h2>
-<p>Generates a delete SQL string and runs the query.<code>	$this-&gt;db-&gt;empty_table('mytable'); <br />
-	<br />
-// Produces<br />
-// DELETE FROM mytable</code></p>
-<h2>$this-&gt;db-&gt;truncate();</h2>
-<p>Generates a truncate SQL string and runs the query.</p>
-<code> $this-&gt;db-&gt;from('mytable'); <br />
-$this-&gt;db-&gt;truncate(); <br />
-// or <br />
-$this-&gt;db-&gt;truncate('mytable'); <br />
-<br />
-// Produce:<br />
-// TRUNCATE mytable <br />
-</code>
-<p class="important"><strong>Note:</strong> If the TRUNCATE command isn't available, truncate() will execute as &quot;DELETE FROM table&quot;.</p>
-
-<h1><a name="chaining">&nbsp;</a>Method Chaining</h1>
-
-<p>Method chaining allows you to simplify your syntax by connecting multiple functions.  Consider this example:</p>
-
-<code>
-<dfn>$this->db</dfn><kbd>-></kbd><var>select</var>('title')<kbd>-></kbd><var>from</var>('mytable')<kbd>-></kbd><var>where</var>('id', $id)<kbd>-></kbd><var>limit</var>(10, 20);<br />
-<br />
-$query = $this->db->get();</code>
-
-<p class="important"><strong>Note:</strong> Method chaining only works with PHP 5.</p>
-
-<p>&nbsp;</p>
-
-<h1><a name="caching">&nbsp;</a>Active Record Caching</h1>
-
-<p>While not &quot;true&quot; caching, Active Record enables you to save (or &quot;cache&quot;) certain parts of your queries for reuse at a later point in your script's execution. Normally, when an Active Record call is completed, all stored information is reset for the next call. With caching, you can prevent this reset, and reuse information easily.</p>
-
-<p>Cached calls are cumulative. If you make 2 cached select() calls, and then 2 uncached select() calls, this will result in 4 select() calls. There are three Caching functions available:</p>
-
-<h2>$this-&gt;db-&gt;start_cache()</h2>
-
-<p>This function must be called to begin caching. All Active Record queries of the correct type (see below for supported queries) are stored for later use.</p>
-
-<h2>$this-&gt;db-&gt;stop_cache()</h2>
-
-<p>This function can be called to stop caching.</p>
-
-<h2>$this-&gt;db-&gt;flush_cache()</h2>
-
-<p>This function deletes all items from the Active Record cache.</p>
-
-<p>Here's a usage example:</p>
-
-<p><code>$this-&gt;db-&gt;start_cache();<br />
-$this-&gt;db-&gt;select('field1');<br />
-$this-&gt;db-&gt;stop_cache();<br /><br />
-$this-&gt;db-&gt;get('tablename');<br />
-<br />
-//Generates: SELECT `field1` FROM (`tablename`)<br />
-<br />
-$this-&gt;db-&gt;select('field2');<br />
-$this-&gt;db-&gt;get('tablename');<br />
-<br />
-//Generates:  SELECT `field1`, `field2` FROM (`tablename`)<br />
-<br />
-$this-&gt;db-&gt;flush_cache();<br />
-<br />
-$this-&gt;db-&gt;select('field2');<br />
-$this-&gt;db-&gt;get('tablename');<br />
-<br />
-//Generates:  SELECT `field2` FROM (`tablename`)</code></p>
-
-<p class="important"> <strong>Note:</strong> The following statements can be cached: select, from, join, where, like, group_by, having, order_by, set</p>

-<h1>Database Caching Class</h1>
-
-<p>The Database Caching Class permits you to cache your queries as text files for reduced database load.</p>
-
-<p class="important"><strong>Important:</strong>&nbsp; This class is initialized automatically by the database driver
-when caching is enabled.  Do NOT load this class manually.<br /><br />
-
-<strong>Also note:</strong>&nbsp; Not all query result functions are available when you use caching. Please read this page carefully.</p>
-
-<h2>Enabling Caching</h2>
-
-<p>Caching is enabled in three steps:</p>
-
-<ul>
-<li>Create a writable directory on your server where the cache files can be stored.</li>
-<li>Set the path to your cache folder in your <dfn>application/config/database.php</dfn> file.</li>
-<li>Enable the caching feature, either globally by setting the preference in your <dfn>application/config/database.php</dfn> file, or manually as described below.</li>
-</ul>
-
-<p>Once enabled, caching will happen automatically whenever a page is loaded that contains database queries.</p>
-
-
-<h2>How Does Caching Work?</h2>
-
-<p>CodeIgniter's query caching system happens dynamically when your pages are viewed.
-When caching is enabled, the first time a web page is loaded, the query result object will
-be serialized and stored in a text file on your server. The next time the page is loaded the cache file will be used instead of
-accessing your database.  Your database usage can effectively be reduced to zero for any pages that have been cached.</p>
-
-<p>Only <dfn>read-type</dfn> (SELECT) queries can be cached, since these are the only type of queries that produce a result.
-<dfn>Write-type</dfn> (INSERT, UPDATE, etc.) queries, since they don't generate a result, will not be cached by the system.</p>
-
-<p>Cache files DO NOT expire.  Any queries that have been cached will remain cached until you delete them.  The caching system
-permits you clear caches associated with individual pages, or you can delete the entire collection of cache files.
-Typically you'll want to use the housekeeping functions described below to delete cache files after certain
-events take place, like when you've added new information to your database.</p>
-
-<h2>Will Caching Improve Your Site's Performance?</h2>
-
-<p>Getting a performance gain as a result of caching depends on many factors.
-If you have a highly optimized database under very little load, you probably won't see a performance boost.
-If your database is under heavy use you probably will see an improved response, assuming your file-system is not
-overly taxed.  Remember that caching simply changes how your information is retrieved, shifting it from being a database
-operation to a file-system one.</p>
-
-<p>In some clustered server environments, for example, caching may be detrimental since file-system operations are so intense.
-On single servers in shared environments, caching will probably be beneficial. Unfortunately there is no
-single answer to the question of whether you should cache your database.  It really depends on your situation.</p>
-
-<h2>How are Cache Files Stored?</h2>
-
-<p>CodeIgniter places the result of EACH query into its own cache file.  Sets of cache files are further organized into
-sub-folders corresponding to your controller functions.  To be precise, the sub-folders are named identically to the
-first two segments of your URI (the controller class name and function name).</p>
-
-<p>For example, let's say you have a controller called <dfn>blog</dfn> with a function called <dfn>comments</dfn> that
-contains three queries.  The caching system will create a cache folder
-called <kbd>blog+comments</kbd>, into which it will write three cache files.</p>
-
-<p>If you use dynamic queries that change based on information in your URI (when using pagination, for example), each instance of
-the query will produce its own cache file.  It's possible, therefore, to end up with many times more cache files than you have
-queries.</p>
-
-
-<h2>Managing your Cache Files</h2>
-
-<p>Since cache files do not expire, you'll need to build deletion routines into your application.  For example, let's say you have a blog
-that allows user commenting.  Whenever a new comment is submitted you'll want to delete the cache files associated with the
-controller function that serves up your comments.  You'll find two delete functions described below that help you
-clear data.</p>
-
-
-<h2>Not All Database Functions Work with Caching</h2>
-
-<p>Lastly, we need to point out that the result object that is cached is a simplified version of the full result object. For that reason,
-some of the query result functions are not available for use.</p>
-
-<p>The following functions <kbd>ARE NOT</kbd> available when using a cached result object:</p>
-
-<ul>
-<li>num_fields()</li>
-<li>field_names()</li>
-<li>field_data()</li>
-<li>free_result()</li>
-</ul>
-
-<p>Also, the two database resources (result_id and conn_id) are not available when caching, since result resources only
-pertain to run-time operations.</p>
-
-
-<br />
-
-<h1>Function Reference</h1>
-
-
-
-<h2>$this->db->cache_on()&nbsp; / &nbsp; $this->db->cache_off()</h2>
-
-<p>Manually enables/disables caching.  This can be useful if you want to
-keep certain queries from being cached.  Example:</p>
-
-<code>
-// Turn caching on<br />
-$this->db->cache_on();<br />
-$query = $this->db->query("SELECT * FROM mytable");<br />
-<br />
-// Turn caching off for this one query<br />
-$this->db->cache_off();<br />
-$query = $this->db->query("SELECT * FROM members WHERE member_id = '$current_user'");<br />
-<br />
-// Turn caching back on<br />
-$this->db->cache_on();<br />
-$query = $this->db->query("SELECT * FROM another_table");
-</code>
-
-
-<h2>$this->db->cache_delete()</h2>
-
-<p>Deletes the cache files associated with a particular page. This is useful if you need to clear caching after you update your database.</p>
-
-<p>The caching system saves your cache files to folders that correspond to the URI of the page you are viewing.  For example, if you are viewing
-a page at <dfn>example.com/index.php/blog/comments</dfn>, the caching system will put all cache files associated with it in a folder
-called <dfn>blog+comments</dfn>.  To delete those particular cache files you will use:</p>
-
-<code>$this->db->cache_delete('blog', 'comments');</code>
-
-<p>If you do not use any parameters the current URI will be used when determining what should be cleared.</p>
-
-
-<h2>$this->db->cache_delete_all()</h2>
-
-<p>Clears all existing cache files.  Example:</p>
-
-<code>$this->db->cache_delete_all();</code>
-

-<h1>Custom Function Calls</h1>
-
-<h2>$this->db->call_function();</h2>
-
-<p>This function enables you to call PHP database functions that are not natively included in CodeIgniter, in a platform independent manner.
-For example, lets say you want to call the <dfn>mysql_get_client_info()</dfn> function, which is <strong>not</strong> natively supported
-by CodeIgniter.  You could do so like this:
-</p>
-
-<code>$this->db->call_function('<var>get_client_info</var>');</code>
-
-<p>You must supply the name of the function, <strong>without</strong> the <var>mysql_</var> prefix, in the first parameter.  The prefix is added
-automatically based on which database driver is currently being used.  This permits you to run the same function on different database platforms.
-Obviously not all function calls are identical between platforms, so there are limits to how useful this function can be in terms of portability.</p>
-
-<p>Any parameters needed by the function you are calling will be added to the second parameter.</p>
-
-<code>$this->db->call_function('<var>some_function</var>', $param1, $param2, etc..);</code>
-
-
-<p>Often, you will either need to supply a database connection ID or a database result ID.  The connection ID can be accessed using:</p>
-
-<code>$this->db->conn_id;</code>
-
-<p>The result ID can be accessed from within your result object, like this:</p>
-
-<code>$query = $this->db->query("SOME QUERY");<br />
-<br />
-<var>$query->result_id;</var></code>

-<h1>Database Configuration</h1>
-
-<p>CodeIgniter has a config file that lets you store your database connection values (username, password, database name, etc.).
-The config file is located at <samp>application/config/database.php</samp>. You can also set database connection values for specific <a href="../libraries/config.html">environments</a> by placing <strong>database.php</strong> it the respective environment config folder.</p>
-
-<p>The config settings are stored in a multi-dimensional array with this prototype:</p>
-
-<code>$db['default']['hostname'] = "localhost";<br />
-$db['default']['username'] = "root";<br />
-$db['default']['password'] = "";<br />
-$db['default']['database'] = "database_name";<br />
-$db['default']['dbdriver'] = "mysql";<br />
-$db['default']['dbprefix'] = "";<br />
-$db['default']['pconnect'] = TRUE;<br />
-$db['default']['db_debug'] = FALSE;<br />
-$db['default']['cache_on'] = FALSE;<br />
-$db['default']['cachedir'] =  &quot;&quot;;<br />
-$db['default']['char_set'] = "utf8";<br />
-$db['default']['dbcollat'] = "utf8_general_ci";<br />
-$db['default']['swap_pre'] = "";<br />
-$db['default']['autoinit'] = TRUE;<br />
-$db['default']['stricton'] = FALSE;</code>
-
-<p>The reason we use a multi-dimensional array rather than a more simple one is to permit you to optionally store
-multiple sets of connection values.  If, for example,  you run multiple environments (development, production, test, etc.)
-under a single installation, you can set up a connection group for each, then switch between groups as needed.
-For example, to set up a "test" environment you would do this:</p>
-
-<code>$db['test']['hostname'] = "localhost";<br />
-$db['test']['username'] = "root";<br />
-$db['test']['password'] = "";<br />
-$db['test']['database'] = "database_name";<br />
-$db['test']['dbdriver'] = "mysql";<br />
-$db['test']['dbprefix'] = "";<br />
-$db['test']['pconnect'] = TRUE;<br />
-$db['test']['db_debug'] = FALSE;<br />
-$db['test']['cache_on'] = FALSE;<br />
-$db['test']['cachedir'] =  &quot;&quot;;<br />
-$db['test']['char_set'] = "utf8";<br />
-$db['test']['dbcollat'] = "utf8_general_ci";<br />
-$db['test']['swap_pre'] = "";<br />
-$db['test']['autoinit'] = TRUE;<br />
-$db['test']['stricton'] = FALSE;</code>
-
-
-<p>Then, to globally tell the system to use that group you would set this variable located in the config file:</p>
-
-<code>$active_group = "test";</code>
-
-<p>Note: The name "test" is arbitrary.  It can be anything you want. By default we've used the word "default"
-for the primary connection, but it too can be renamed to something more relevant to your project.</p>
-
-<h3>Active Record</h3>
-
-<p>The <a href="active_record.html">Active Record Class</a> is globally enabled or disabled by setting the $active_record variable in the database configuration file to TRUE/FALSE (boolean). If you are not using the active record class, setting it to FALSE will utilize fewer resources when the database classes are initialized.</p>
-
-<code>$active_record = TRUE;</code>
-
-<p class="important"><strong>Note:</strong> that some CodeIgniter classes such as Sessions require Active Records be enabled to access certain functionality.</p>
-
-<h3>Explanation of Values:</h3>
-
-<ul>
-<li><strong>hostname</strong> - The hostname of your database server. Often this is "localhost".</li>
-<li><strong>username</strong> - The username used to connect to the database.</li>
-<li><strong>password</strong> - The password used to connect to the database.</li>
-<li><strong>database</strong> - The name of the database you want to connect to.</li>
-<li><strong>dbdriver</strong> - The database type. ie: mysql, postgres, odbc, etc. Must be specified in lower case.</li>
-<li><strong>dbprefix</strong> - An optional table prefix which will added to the table name when running <a href="active_record.html">Active Record</a> queries.  This permits multiple CodeIgniter installations to share one database.</li>
-<li><strong>pconnect</strong> - TRUE/FALSE (boolean) - Whether to use a persistent connection.</li>
-<li><strong>db_debug</strong> - TRUE/FALSE (boolean) - Whether database errors should be displayed.</li>
-<li><strong>cache_on</strong> - TRUE/FALSE (boolean) - Whether database query caching is enabled, see also <a href="caching.html">Database Caching Class</a>.</li>
-<li><strong>cachedir</strong> - The absolute server path to your database query cache directory.</li>
-<li><strong>char_set</strong> - The character set used in communicating with the database.</li>
-<li><strong>dbcollat</strong> - The character collation used in communicating with the database. <p class="important"><strong>Note:</strong> For MySQL and MySQLi databases, this setting is only used as a backup if your server is running PHP &lt; 5.2.3 or MySQL &lt; 5.0.7 (and in table creation queries made with DB Forge). There is an incompatibility in PHP with mysql_real_escape_string() which can make your site vulnerable to SQL injection if you are using a multi-byte character set and are running versions lower than these. Sites using Latin-1 or UTF-8 database character set and collation are unaffected.</p></li>
-<li><strong>swap_pre</strong> - A default table prefix that should be swapped with <var>dbprefix</var>. This is useful for distributed applications where you might run manually written queries, and need the prefix to still be customizable by the end user.</li>
-<li><strong>autoinit</strong> - Whether or not to automatically connect to the database when the library loads. If set to false, the connection will take place prior to executing the first query.</li>
-<li><strong>stricton</strong> - TRUE/FALSE (boolean) - Whether to force "Strict Mode" connections, good for ensuring strict SQL while developing an application.</li>
-<li><strong>port</strong> - The database port number.  To use this value you have to add a line to the database config array.<code>$db['default']['port'] =  5432;</code>
-</ul>
-
-<p class="important"><strong>Note:</strong> Depending on what database platform you are using (MySQL, Postgres, etc.)
-not all values will be needed.  For example, when using SQLite you will not need to supply a username or password, and
-the database name will be the path to your database file. The information above assumes you are using MySQL.</p>

-<h1>Connecting to your Database</h1>
-
-<p>There are two ways to connect to a database:</p>
-
-<h2>Automatically Connecting</h2>
-
-<p>The "auto connect" feature will load and instantiate the database class with every page load.
-To enable "auto connecting", add the word <var>database</var> to the library array, as indicated in the following file:</p>
-
-<p><kbd>application/config/autoload.php</kbd></p>
-
-<h2>Manually Connecting</h2>
-
-<p>If only some of your pages require database connectivity you can manually connect to your database by adding this
-line of code in any function where it is needed, or in your class constructor to make the database
-available globally in that class.</p>
-
-<code>$this->load->database();</code>
-
-<p class="important">If the above function does <strong>not</strong> contain any information in the first parameter it will connect
-to the group specified in your database config file. For most people, this is the preferred method of use.</p>
-
-<h3>Available Parameters</h3>
-
-<ol>
-	<li>The database connection values, passed either as an array or a DSN string.</li>
-	<li>TRUE/FALSE (boolean).  Whether to return the connection ID (see Connecting to Multiple Databases below).</li>
-	<li>TRUE/FALSE (boolean).  Whether to enable the Active Record class.  Set to TRUE by default.</li>
-</ol>
-
-
-<h3>Manually Connecting to a Database</h3>
-
-<p>The first parameter of this function can <strong>optionally</strong> be used to specify a particular database group
-from your config file, or you can even submit connection values for a database that is not specified in your config file.
-Examples:</p>
-
-<p>To choose a specific group from your config file you can do this:</p>
-
-<code>$this->load->database('<samp>group_name</samp>');</code>
-
-<p>Where <samp>group_name</samp> is the name of the connection group from your config file.</p>
-
-
-<p>To connect manually to a desired database you can pass an array of values:</p>
-
-<code>$config['hostname'] = "localhost";<br />
-$config['username'] = "myusername";<br />
-$config['password'] = "mypassword";<br />
-$config['database'] = "mydatabase";<br />
-$config['dbdriver'] = "mysql";<br />
-$config['dbprefix'] = "";<br />
-$config['pconnect'] = FALSE;<br />
-$config['db_debug'] = TRUE;<br />
-$config['cache_on'] = FALSE;<br />
-$config['cachedir'] = "";<br />
-$config['char_set'] = "utf8";<br />
-$config['dbcollat'] = "utf8_general_ci";<br />
-<br />
-$this->load->database(<samp>$config</samp>);</code>
-
-<p>For information on each of these values please see the <a href="configuration.html">configuration page</a>.</p>
-
-<p class="important"><strong>Note:</strong> For the PDO driver, $config['hostname'] should look like this: 'mysql:host=localhost'</p>
-
-<p>Or you can submit your database values as a Data Source Name. DSNs must have this prototype:</p>
-
-<code>$dsn = 'dbdriver://username:password@hostname/database';<br />
-<br />
-$this->load->database(<samp>$dsn</samp>);</code>
-
-<p>To override default config values when connecting with a DSN string, add the config variables as a query string.</p>
-
-<code>$dsn = 'dbdriver://username:password@hostname/database?char_set=utf8&amp;dbcollat=utf8_general_ci&amp;cache_on=true&amp;cachedir=/path/to/cache';<br />
-<br />
-$this->load->database(<samp>$dsn</samp>);</code>
-
-<h2>Connecting to Multiple Databases</h2>
-
-<p>If you need to connect to more than one database simultaneously you can do so as follows:</p>
-
-
-<code>$DB1 = $this->load->database('group_one', TRUE);<br />
-$DB2 = $this->load->database('group_two', TRUE);
-</code>
-
-<p>Note: Change the words "group_one" and "group_two" to the specific group names you are connecting to (or
-you can pass the connection values as indicated above).</p>
-
-<p>By setting the second parameter to TRUE (boolean) the function will return the database object.</p>
-
-<div class="important">
-<p>When you connect this way, you will use your object name to issue commands rather than the syntax used throughout this guide.  In other words, rather than issuing commands with:</p>
-
-<p>$this->db->query();<br />$this->db->result();<br /> etc...</p>
-
-<p>You will instead use:</p>
-
-<p>$DB1->query();<br />$DB1->result();<br /> etc...</p>
-
-</div>
-
-<h2>Reconnecting / Keeping the Connection Alive</h2>
-
-<p>If the database server's idle timeout is exceeded while you're doing some heavy PHP lifting (processing an image, for instance), you should consider pinging the server by using the <dfn>reconnect()</dfn> method before sending further queries, which can gracefully keep the connection alive or re-establish it.</p>
-
-<code>$this->db->reconnect();</code>
-
-<h2>Manually closing the Connection</h2>
-
-<p>While CodeIgniter intelligently takes care of closing your database connections, you can explicitly close the connection.</p>
-
-<code>$this->db->close();</code>

-
-<p>The following page contains example code showing how the database class is used.  For complete details please
-read the individual pages describing each function.</p>
-
-
-<h2>Initializing the Database Class</h2>
-
-<p>The following code loads and initializes the database class based on your <a href="configuration.html">configuration</a> settings:</p>
-
-<code>$this->load->database();</code>
-
-<p>Once loaded the class is ready to be used as described below.</p>
-
-<p>Note: If all your pages require database access you can connect automatically.  See the <a href="connecting.html">connecting</a> page for details.</p>
-
-
-<h2>Standard Query With Multiple Results (Object Version)</h2>
-
-<code>$query = $this->db->query('SELECT name, title, email FROM my_table');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->email;<br />
-}<br />
-<br />
-echo 'Total Results: ' . $query->num_rows();
-</code>
-
-<p>The above <dfn>result()</dfn> function returns an array of <strong>objects</strong>.  Example:  $row->title</p>
-
-
-<h2>Standard Query With Multiple Results (Array Version)</h2>

-<p>The above <dfn>result_array()</dfn> function returns an array of standard array indexes.  Example:  $row['title']</p>
-
-
-<h2>Testing for Results</h2>
-
-<p>If you run queries that might <strong>not</strong> produce a result, you are encouraged to test for a result first
-using the <dfn>num_rows()</dfn> function:</p>
-
-<code>
-$query = $this->db->query("YOUR QUERY");<br />
-<br />
-if ($query->num_rows() > 0)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;foreach ($query->result() as $row)<br />
-&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->body;<br />
-&nbsp;&nbsp;&nbsp;}<br />
-}
-</code>
-
-
-
-
-<h2>Standard Query With Single Result</h2>
-
-<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
-<br />
-$row = $query->row();<br />
-echo $row->name;<br />
-</code>
-
-<p>The above <dfn>row()</dfn> function returns an <strong>object</strong>.  Example:  $row->name</p>
-
-
-<h2>Standard Query With Single Result (Array version)</h2>
-
-<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
-<br />
-$row = $query->row_array();<br />
-echo $row['name'];<br />
-</code>
-
-<p>The above <dfn>row_array()</dfn> function returns an <strong>array</strong>.  Example:  $row['name']</p>
-
-
-<h2>Standard Insert</h2>
-
-<code>
-$sql = "INSERT INTO mytable (title, name) <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VALUES (".$this->db->escape($title).", ".$this->db->escape($name).")";<br />
-<br />
-$this->db->query($sql);<br />
-<br />
-echo $this->db->affected_rows();
-</code>
-
-
-
-
-<h2>Active Record Query</h2>
-
-<p>The <a href="active_record.html">Active Record Pattern</a> gives you a simplified means of retrieving data:</p>
-
-<code>
-$query = $this->db->get('table_name');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-}</code>
-
-<p>The above <dfn>get()</dfn> function retrieves all the results from the supplied table.
-The <a href="active_record.html">Active Record</a> class contains a full compliment of functions
-for working with data.</p>
-
-
-<h2>Active Record Insert</h2>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => $title,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => $name,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => $date<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->db->insert('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('{$title}', '{$name}', '{$date}')</code>

-<h1>Field Data</h1>
-
-
-<h2>$this->db->list_fields()</h2>
-<p>Returns an array containing the field names. This query can be called two ways:</p>
-
-
-<p>1. You can supply the table name and call it from the <dfn>$this->db-></dfn> object:</p>
-
-<code>
-$fields = $this->db->list_fields('table_name');<br /><br />
-
-foreach ($fields as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field;<br />
-}
-</code>
-
-<p>2. You can gather the field names associated with any query you run by calling the function
-from your query result object:</p>
-
-<code>
-$query = $this->db->query('SELECT * FROM some_table');
-<br /><br />
-
-foreach ($query->list_fields() as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field;<br />
-}
-</code>
-
-
-<h2>$this->db->field_exists()</h2>
-
-<p>Sometimes it's helpful to know whether a particular field exists before performing an action.
-Returns a boolean TRUE/FALSE.  Usage example:</p>
-
-<code>
-if ($this->db->field_exists('field_name', 'table_name'))<br />
-{<br />
-&nbsp;&nbsp; // some code...<br />
-}
-</code>
-
-<p>Note:  Replace <em>field_name</em> with the name of the column you are looking for, and replace
-<em>table_name</em> with the name of the table you are looking for.</p>
-
-
-<h2>$this->db->field_data()</h2>
-<p>Returns an array of objects containing field information.</p>
-<p>Sometimes it's helpful to gather the field names or other metadata, like the column type, max length, etc.</p>
-
-
-<p class="important">Note: Not all databases provide meta-data.</p>
-
-<p>Usage example:</p>
-
-<code>
-$fields = $this->db->field_data('table_name');<br /><br />
-
-foreach ($fields as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field->name;<br />
-&nbsp;&nbsp;&nbsp;echo $field->type;<br />
-&nbsp;&nbsp;&nbsp;echo $field->max_length;<br />
-&nbsp;&nbsp;&nbsp;echo $field->primary_key;<br />
-}
-</code>
-
-<p>If you have run a query already you can use the result object instead of supplying the table name:</p>
-
-<code>
-$query = $this->db->query("YOUR QUERY");<br />
-$fields = $query->field_data();
-</code>
-
-
-<p>The following data is available from this function if supported by your database:</p>
-
-<ul>
-<li>name - column name</li>
-<li>max_length - maximum length of the column</li>
-<li>primary_key - 1 if the column is a primary key</li>
-<li>type - the type of the column</li>
-</ul>

-<h2><a name="init"></a>Initializing the Forge Class</h2>
-
-<p class="important"><strong>Important:</strong>&nbsp; In order to initialize the Forge class, your database driver must
-already be running, since the forge class relies on it.</p>
-
-<p>Load the Forge Class as follows:</p>
-
-<code>$this->load->dbforge()</code>
-
-<p>Once initialized you will access the functions using the <dfn>$this->dbforge</dfn> object:</p>
-
-<code>$this->dbforge->some_function()</code>
-<h2><a name="create"></a>$this->dbforge->create_database('db_name')</h2>
-
-<p>Permits you to create the database specified in the first parameter. Returns TRUE/FALSE based on success or failure:</p>
-
-<code>if ($this->dbforge->create_database('my_db'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo 'Database created!';<br />
-}</code>
-
-
-
-
-<h2><a name="drop"></a>$this->dbforge->drop_database('db_name')</h2>
-
-<p>Permits you to drop the database specified in the first parameter. Returns TRUE/FALSE based on success or failure:</p>
-
-<code>if ($this->dbforge->drop_database('my_db'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo 'Database deleted!';<br />
-}</code>
-
-
-<h1>Creating and Dropping Tables</h1>
-<p>There are several things you may wish to do when creating tables. Add fields, add keys to the table, alter columns. CodeIgniter provides a mechanism for this.</p>
-<h2><a name="add_field" id="add_field"></a>Adding fields</h2>
-<p>Fields are created via an associative array. Within the array you must include a 'type' key that relates to the datatype of the field. For example, INT, VARCHAR, TEXT, etc. Many datatypes (for example VARCHAR) also require a 'constraint' key.</p>
-<p><code>$fields = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'users' =&gt; array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'VARCHAR',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'constraint' =&gt; '100',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-	<br />
-// will translate to &quot;users VARCHAR(100)&quot; when the field is added.</code></p>
-<p>Additionally, the following key/values can be used:</p>
-<ul>
-	<li>unsigned/true : to generate &quot;UNSIGNED&quot; in the field definition.</li>
-	<li>default/value : to generate a default value in the field definition.</li>
-	<li>null/true : to generate &quot;NULL&quot; in the field definition. Without this, the field will default to &quot;NOT NULL&quot;.</li>
-	<li>auto_increment/true : generates an auto_increment flag on the field. Note that the field type must be a type that supports this, such as integer.</li>
-	</ul>
-<p><code>$fields = array(<br />

-</code></p>
-<p>After the fields have been defined, they can  be added  using <dfn>$this-&gt;dbforge-&gt;add_field($fields);</dfn> followed by a call to the <dfn>create_table()</dfn> function.</p>
-<h3>$this-&gt;dbforge-&gt;add_field()</h3>
-<p>The add fields function will accept the above array.</p>
-<h3>Passing strings as fields</h3>
-<p>If you know exactly how you want a field to be created, you can pass the string into the field definitions with add_field()</p>
-<p><code>$this-&gt;dbforge-&gt;add_field(&quot;label varchar(100) NOT NULL DEFAULT 'default label'&quot;);</code></p>
-<p class="important">Note: Multiple calls to <dfn>add_field()</dfn> are cumulative.</p>
-<h3>Creating an id field</h3>
-<p>There is a special exception for creating id fields. A field with type id will automatically be assinged as an INT(9) auto_incrementing Primary Key.</p>
-<p><code>$this-&gt;dbforge-&gt;add_field('id');<br />
-	// gives id INT(9) NOT NULL AUTO_INCREMENT</code></p>
-<h2><a name="add_key" id="add_key"></a>Adding Keys</h2>
-<p>Generally speaking, you'll want your table to have Keys. This is accomplished with <dfn>$this-&gt;dbforge-&gt;add_key('field')</dfn>. An optional second parameter set to TRUE will make it a primary key. Note that <dfn>add_key()</dfn> must be followed by a call to <dfn>create_table()</dfn>.</p>
-<p>Multiple column non-primary keys must be sent as an array.  Sample output below is for MySQL.</p>
-<p><code>$this-&gt;dbforge-&gt;add_key('blog_id', TRUE);<br />
-	// gives PRIMARY KEY `blog_id` (`blog_id`)<br />
-	<br />
-	$this-&gt;dbforge-&gt;add_key('blog_id', TRUE);<br />
-	$this-&gt;dbforge-&gt;add_key('site_id', TRUE);<br />
-	// gives PRIMARY KEY `blog_id_site_id` (`blog_id`, `site_id`)<br />
-	<br />
-	$this-&gt;dbforge-&gt;add_key('blog_name');<br />
-	// gives KEY `blog_name` (`blog_name`)<br />
-	<br />
-	$this-&gt;dbforge-&gt;add_key(array('blog_name', 'blog_label'));<br />
-	// gives KEY `blog_name_blog_label` (`blog_name`, `blog_label`)</code></p>
-<h2><a name="create_table" id="create_table"></a>Creating a table</h2>
-<p>After fields and keys have been declared, you can create a new table with</p>
-<p><code>$this-&gt;dbforge-&gt;create_table('table_name');<br />
-// gives CREATE TABLE table_name</code></p>
-<p>An optional second parameter set to TRUE adds an &quot;IF NOT EXISTS&quot; clause into the definition</p>
-<p><code>$this-&gt;dbforge-&gt;create_table('table_name', TRUE);<br />
-// gives CREATE TABLE IF NOT EXISTS table_name</code></p>
-<h2><a name="drop_table" id="drop_table"></a>Dropping a table</h2>
-<p>Executes a DROP TABLE sql</p>
-<p><code>$this-&gt;dbforge-&gt;drop_table('table_name');<br />
-	// gives DROP TABLE IF EXISTS  table_name</code></p>
-<h2><a name="rename_table" id="rename_table"></a>Renaming a table</h2>
-<p>Executes a TABLE rename</p>
-<p><code>$this-&gt;dbforge-&gt;rename_table('old_table_name', 'new_table_name');<br />
-	// gives ALTER TABLE old_table_name RENAME TO new_table_name</code></p>
-<h1><a name="modifying_tables" id="modifying_tables"></a>Modifying Tables</h1>
-<h2>$this-&gt;dbforge-&gt;add_column()</h2>
-<p>The add_column() function is used to modify an existing table. It accepts the same field array as above, and can be used for an unlimited number of additional fields.</p>
-<p><code>$fields = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'preferences' =&gt; array('type' =&gt; 'TEXT')<br />
-);<br />
-$this-&gt;dbforge-&gt;add_column('table_name', $fields);<br />
-<br />
-// gives ALTER TABLE table_name ADD   	preferences TEXT</code></p>
-<p>An optional third parameter can be used to specify which existing column to add the new column after.</p>
-<p><code>
-$this-&gt;dbforge-&gt;add_column('table_name', $fields, 'after_field');
-</code></p>
-<h2>$this-&gt;dbforge-&gt;drop_column()</h2>
-<p>Used to remove a column from a table. </p>
-<p><code>$this-&gt;dbforge-&gt;drop_column('table_name', 'column_to_drop');</code></p>
-<h2>$this-&gt;dbforge-&gt;modify_column()</h2>
-<p>The usage of this function is identical to add_column(), except it alters an existing column rather than adding a new one. In order to change the name you can add a &quot;name&quot; key into the field defining array.</p>
-<p><code>$fields = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'old_name' =&gt; array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' =&gt; 'new_name',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'TEXT',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-);<br />
-$this-&gt;dbforge-&gt;modify_column('table_name', $fields);<br />

-<h1>Query Helper Functions</h1>
-
-
-<h2>$this->db->insert_id()</h2>
-<p>The insert ID number when performing database inserts.</p>
-<p class="important"><strong>Note:</strong> If using the PDO driver with PostgreSQL, this function requires a $name parameter, which specifies the appropriate sequence to check for the insert id.</p>
-
-<h2>$this->db->affected_rows()</h2>
-<p>Displays the number of affected rows, when doing "write" type queries (insert, update, etc.).</p>
-<p>Note:  In MySQL "DELETE FROM TABLE" returns 0 affected rows. The database class has a small hack that allows it to return the correct number of affected rows.  By default this hack is enabled but it can be turned off in the database driver file.</p>
-
-
-<h2>$this->db->count_all();</h2>
-<p>Permits you to determine the number of rows in a particular table.  Submit the table name in the first parameter. Example:</p>
-<code>echo $this->db->count_all('<var>my_table</var>');<br />
-<br />
-// Produces an integer, like 25
-</code>
-
-
-<h2>$this->db->platform()</h2>
-<p>Outputs the database platform you are running (MySQL, MS SQL, Postgres, etc...):</p>
-<code>echo $this->db->platform();</code>
-
-
-<h2>$this->db->version()</h2>
-<p>Outputs the database version you are running:</p>
-<code>echo $this->db->version();</code>
-
-
-<h2>$this->db->last_query();</h2>
-<p>Returns the last query that was run (the query string, not the result).  Example:</p>
-
-<code>$str = $this->db->last_query();<br />
-<br />
-// Produces:  SELECT * FROM sometable....
-</code>
-
-
-<p>The following two functions help simplify the process of writing database INSERTs and UPDATEs.</p>
-
-
-<h2>$this->db->insert_string(); </h2>
-<p>This function simplifies the process of writing database inserts. It returns a correctly formatted SQL insert string. Example:</p>
-
-<code>$data = array('name' => $name, 'email' => $email, 'url' => $url);<br />
-<br />
-$str = $this->db->insert_string('table_name', $data);
-</code>
-
-<p>The first parameter is the table name, the second is an associative array with the data to be inserted.  The above example produces:</p>
-<code>INSERT INTO table_name (name, email, url) VALUES ('Rick', 'rick@example.com', 'example.com')</code>
-
-<p class="important">Note: Values are automatically escaped, producing safer queries.</p>
-
-
-
-<h2>$this->db->update_string(); </h2>
-<p>This function simplifies the process of writing database updates. It returns a correctly formatted SQL update string. Example:</p>
-
-<code>$data = array('name' => $name, 'email' => $email, 'url' => $url);<br />
-<br />
-$where = "author_id = 1 AND status = 'active'";
-<br /><br />
-$str = $this->db->update_string('table_name', $data, $where);
-</code>
-
-<p>The first parameter is the table name, the second is an associative array with the data to be updated, and the third parameter is the "where" clause. The above example produces:</p>
-<code> UPDATE table_name SET name = 'Rick', email = 'rick@example.com', url = 'example.com' WHERE author_id = 1 AND status = 'active'</code>
-
-<p class="important">Note: Values are automatically escaped, producing safer queries.</p>

-<h1>Queries</h1>
-
-<h2>$this->db->query();</h2>
-
-<p>To submit a query, use the following function:</p>
-
-<code>$this->db->query('YOUR QUERY HERE');</code>
-
-<p>The <dfn>query()</dfn> function returns a database result <strong>object</strong> when "read" type queries are run,
-which you can use to <a href="results.html">show your results</a>.  When "write" type queries are run it simply returns TRUE or FALSE
-depending on success or failure.  When retrieving data you will typically assign the query to your own variable, like this:</p>
-
-<code><var>$query</var> = $this->db->query('YOUR QUERY HERE');</code>
-
-<h2>$this->db->simple_query();</h2>
-
-<p>This is a simplified version of the <dfn>$this->db->query()</dfn> function.  It ONLY returns TRUE/FALSE on success or failure.
-It DOES NOT return a database result set, nor does it set the query timer, or compile bind data, or store your query for debugging.
-It simply lets you submit a query. Most users will rarely use this function.</p>
-
-
-<h1>Working with Database prefixes manually</h1>
-<p>If you have configured a database prefix and would like to prepend it to a table name for use in a native SQL query for example, then you can use the following:</p>
-<p><code>$this-&gt;db-&gt;dbprefix('tablename');<br />
-// outputs prefix_tablename</code></p>
-
-<p>If for any reason you would like to change the prefix programatically without needing to create a new connection, you can use this method:</p>
-<p><code>$this-&gt;db-&gt;set_dbprefix('newprefix');<br /><br />
-$this-&gt;db-&gt;dbprefix('tablename');<br />
-// outputs newprefix_tablename</code></p>
-
-
-<h1>Protecting identifiers</h1>
-<p>In many databases it is advisable to protect table and field names - for example with backticks in MySQL. <strong>Active Record queries are automatically protected</strong>, however if you need to manually protect an identifier you can use:</p>
-<p><code>$this-&gt;db-&gt;protect_identifiers('table_name');</code></p>
-
-<p>This function will also add a table prefix to your table, assuming you have a prefix specified in your database config file. To enable the prefixing set <kbd>TRUE</kbd> (boolen) via the second parameter:</p>
-<p><code>$this-&gt;db-&gt;protect_identifiers('table_name', <kbd>TRUE</kbd>);</code></p>
-
-
-<h1>Escaping Queries</h1>
-<p>It's a very good security practice to escape your data before submitting it into your database.
-CodeIgniter has three methods that help you do this:</p>
-
-<ol>
-<li><strong>$this->db->escape()</strong> This function determines the data type so that it
-can escape only string data.  It also automatically adds single quotes around the data so you don't have to:
-
-<code>$sql = "INSERT INTO table (title) VALUES(".$this->db->escape($title).")";</code></li>
-
-<li><strong>$this->db->escape_str()</strong>  This function escapes the data passed to it, regardless of type.
-Most of the time you'll use the above function rather than this one. Use the function like this:
-
-<code>$sql = "INSERT INTO table (title) VALUES('".$this->db->escape_str($title)."')";</code></li>
-
-<li><strong>$this->db->escape_like_str()</strong>  This method should be used when strings are to be used in LIKE
-conditions so that LIKE wildcards ('%', '_') in the string are also properly escaped.
-
-<code>$search = '20% raise';<br />
-$sql = "SELECT id FROM table WHERE column LIKE '%".$this->db->escape_like_str($search)."%'";</code></li>
-
-</ol>
-
-
-<h1>Query Bindings</h1>
-
-
-<p>Bindings enable you to simplify your query syntax by letting the system put the queries together for you. Consider the following example:</p>
-
-<code>
-$sql = "SELECT * FROM some_table WHERE id = <var>?</var> AND status = <var>?</var> AND author = <var>?</var>";
-<br /><br />
-$this->db->query($sql, array(3, 'live', 'Rick'));
-</code>
-
-<p>The question marks in the query are automatically replaced with the values in the array in the second parameter of the query function.</p>
-<p class="important">The secondary benefit of using binds is that the values are automatically escaped, producing safer queries.  You don't have to remember to manually escape data; the engine does it automatically for you.</p>

-<h1>Generating Query Results</h1>
-
-
-<p>There are several ways to generate query results:</p>
-
-	<h2>result()</h2>
-
-	<p>This function returns the query result as an array of <strong>objects</strong>, or <strong>an empty array</strong> on failure.
-
-	Typically you'll use this in a foreach loop, like this:</p>
-
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	foreach ($query->result() as $row)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-	&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-	&nbsp;&nbsp;&nbsp;echo $row->body;<br />
-	}</code>
-
-	<p>The above <dfn>function</dfn> is an alias of <dfn>result_object()</dfn>.</p>
-
-	<p>If you run queries that might <strong>not</strong> produce a result, you are encouraged to test the result first:</p>
-
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	if ($query->num_rows() > 0)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;foreach ($query->result() as $row)<br />
-	&nbsp;&nbsp;&nbsp;{<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->body;<br />
-	&nbsp;&nbsp;&nbsp;}<br />
-	}
-	</code>
-
-	<p>You can also pass a string to result() which represents a class to instantiate for each result object (note: this class must be loaded)</p>
-
-	<code>
-	$query = $this->db->query("SELECT * FROM users;");<br />
-	<br />
-	foreach ($query->result('User') as $user)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;echo $user->name; // call attributes<br />
-	&nbsp;&nbsp;&nbsp;echo $user->reverse_name(); // or methods defined on the 'User' class<br />
-	}
-	</code>
-
-	<h2>result_array()</h2>
-
-	<p>This function returns the query result as a pure array, or an empty array when no result is produced.  Typically you'll use this in a foreach loop, like this:</p>
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	foreach ($query->result_array() as $row)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;echo $row['title'];<br />
-	&nbsp;&nbsp;&nbsp;echo $row['name'];<br />
-	&nbsp;&nbsp;&nbsp;echo $row['body'];<br />
-	}</code>
-
-
-	<h2>row()</h2>
-
-	<p>This function returns a single result row.  If your query has more than one row, it returns only the first row.
-	The result is returned as an <strong>object</strong>.  Here's a usage example:</p>
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	if ($query->num_rows() > 0)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;$row = $query->row();
-	<br /><br />
-	&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-	&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-	&nbsp;&nbsp;&nbsp;echo $row->body;<br />
-	}
-	</code>
-
-	<p>If you want a specific row returned you can submit the row number as a digit in the first parameter:</p>
-
-	<code>$row = $query->row(<dfn>5</dfn>);</code>
-
-	<p>You can also add a second String parameter, which is the name of a class to instantiate the row with:</p>
-
-	<code>
-	$query = $this->db->query("SELECT * FROM users LIMIT 1;");<br />
-	<br />
-	$query->row(0, 'User')<br />
-	echo $row->name; // call attributes<br />
-	echo $row->reverse_name(); // or methods defined on the 'User' class<br />
-	</code>
-
-	<h2>row_array()</h2>
-
-	<p>Identical to the above <var>row()</var> function, except it returns an array.  Example:</p>
-
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	if ($query->num_rows() > 0)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;$row = $query->row_array();
-	<br /><br />
-	&nbsp;&nbsp;&nbsp;echo $row['title'];<br />
-	&nbsp;&nbsp;&nbsp;echo $row['name'];<br />
-	&nbsp;&nbsp;&nbsp;echo $row['body'];<br />
-	}
-	</code>
-
-
-	<p>If you want a specific row returned you can submit the row number as a digit in the first parameter:</p>
-
-	<code>$row = $query->row_array(<dfn>5</dfn>);</code>
-
-
-	<p>In addition, you can walk forward/backwards/first/last through your results using these variations:</p>
-
-<p>
-	<strong>$row = $query->first_row()</strong><br />
-	<strong>$row = $query->last_row()</strong><br />
-	<strong>$row = $query->next_row()</strong><br />
-	<strong>$row = $query->previous_row()</strong>
-</p>
-
-<p>By default they return an object unless you put the word "array" in the parameter:</p>
-
-<p>
-	<strong>$row = $query->first_row('array')</strong><br />
-	<strong>$row = $query->last_row('array')</strong><br />
-	<strong>$row = $query->next_row('array')</strong><br />
-	<strong>$row = $query->previous_row('array')</strong>
-</p>
-
-
-
-<h1>Result Helper Functions</h1>
-
-
-<h2>$query->num_rows()</h2>
-<p>The number of rows returned by the query. Note: In this example, <dfn>$query</dfn> is the variable that the query result object is assigned to:</p>
-
-<code>$query = $this->db->query('SELECT * FROM my_table');<br /><br />
-echo $query->num_rows();
-</code>
-
-<h2>$query->num_fields()</h2>
-<p>The number of FIELDS (columns) returned by the query.  Make sure to call the function using your query result object:</p>
-
-<code>$query = $this->db->query('SELECT * FROM my_table');<br /><br />
-echo $query->num_fields();
-</code>
-
-
-
-<h2>$query->free_result()</h2>
-<p>It frees the memory associated with the result and deletes the result resource ID.  Normally PHP frees its memory automatically at the end of script
-execution.  However, if you are running a lot of queries in a particular script you might want to free the result after each query result has been
-generated in order to cut down on memory consumptions.  Example:
-</p>
-
-<code>$query = $this->db->query('SELECT title FROM my_table');<br /><br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-}<br />
-$query->free_result();  // The $query result object will no longer be available<br />
-<br />
-$query2 = $this->db->query('SELECT name FROM some_table');<br /><br />
-$row = $query2->row();<br />
-echo $row->name;<br />
-$query2->free_result();  // The $query2 result object will no longer be available
-</code>

-<h1>Transactions</h1>
-
-<p>CodeIgniter's database abstraction allows you to use <dfn>transactions</dfn> with databases that support transaction-safe table types.  In MySQL, you'll need
-to be running InnoDB or BDB table types rather than the more common MyISAM.  Most other database platforms support transactions natively.</p>
-
-<p>If you are not familiar with
-transactions we recommend you find a good online resource to learn about them for your particular database.  The information below assumes you
-have a basic understanding of transactions.
-</p>
-
-<h2>CodeIgniter's Approach to Transactions</h2>
-
-<p>CodeIgniter utilizes an approach to transactions that is very similar to the process used by the popular database class ADODB.  We've chosen that approach
-because it greatly simplifies the process of running transactions.  In most cases all that is required are two lines of code.</p>
-
-<p>Traditionally, transactions have required a fair amount of work to implement since they demand that you to keep track of your queries
-and determine whether to <dfn>commit</dfn> or <dfn>rollback</dfn> based on the success or failure of your queries. This is particularly cumbersome with
-nested queries. In contrast,
-we've implemented a smart transaction system that does all this for you automatically (you can also manage your transactions manually if you choose to,
-but there's really no benefit).</p>
-
-<h2>Running Transactions</h2>
-
-<p>To run your queries using transactions you will use the <dfn>$this->db->trans_start()</dfn> and <dfn>$this->db->trans_complete()</dfn> functions as follows:</p>
-
-<code>
-<kbd>$this->db->trans_start();</kbd><br />
-$this->db->query('AN SQL QUERY...');<br />
-$this->db->query('ANOTHER QUERY...');<br />
-$this->db->query('AND YET ANOTHER QUERY...');<br />
-<kbd>$this->db->trans_complete();</kbd>
-</code>
-
-<p>You can run as many queries as you want between the start/complete functions and they will all be committed or rolled back based on success or failure
-of any given query.</p>
-
-
-<h2>Strict Mode</h2>
-
-<p>By default CodeIgniter runs all transactions in <dfn>Strict Mode</dfn>.  When strict mode is enabled, if you are running multiple groups of
-transactions, if one group fails all groups will be rolled back. If strict mode is disabled, each group is treated independently, meaning
-a failure of one group will not affect any others.</p>
-
-<p>Strict Mode can be disabled as follows:</p>
-
-<code>$this->db->trans_strict(FALSE);</code>
-
-
-<h2>Managing Errors</h2>
-
-<p>If you have error reporting enabled in your <dfn>config/database.php</dfn> file you'll see a standard error message if the commit was unsuccessful. If debugging is turned off, you can
-manage your own errors like this:</p>
-
-<code>
-$this->db->trans_start();<br />
-$this->db->query('AN SQL QUERY...');<br />
-$this->db->query('ANOTHER QUERY...');<br />
-$this->db->trans_complete();<br />
-<br />
-if (<kbd>$this->db->trans_status()</kbd> === FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;// generate an error... or use the log_message() function to log your error<br />
-}
-</code>
-
-
-<h2>Enabling Transactions</h2>
-
-<p>Transactions are enabled automatically the moment you use <dfn>$this->db->trans_start()</dfn>.  If you would like to disable transactions you
-can do so using <dfn>$this->db->trans_off()</dfn>:</p>
-
-<code>
-<kbd>$this->db->trans_off()</kbd><br /><br />
-
-$this->db->trans_start();<br />
-$this->db->query('AN SQL QUERY...');<br />
-$this->db->trans_complete();
-</code>
-
-<p class="important">When transactions are disabled, your queries will be auto-commited, just as they are when running queries without transactions.</p>
-
-
-<h2>Test Mode</h2>
-
-<p>You can optionally put the transaction system into "test mode", which will cause your queries to be rolled back -- even if the queries produce a valid result.
-To use test mode simply set the first parameter in the <dfn>$this->db->trans_start()</dfn> function to <samp>TRUE</samp>:</p>

-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->db->trans_commit();<br />
-}<br />
-</code>
-
-<p class="important"><strong>Note:</strong> Make sure to use <kbd>$this->db->trans_begin()</kbd> when running manual transactions, <strong>NOT</strong>
-<dfn>$this->db->trans_start()</dfn>.</p>

-<h1>Database Utility Class</h1>
-
-<p>The Database Utility Class contains functions that help you manage your database.</p>
-
-<h3>Table of Contents</h3>
-

-<li><a href="#list">Listing your Databases</a></li>
-<li><a href="#exists">Checking for a specific Database</a></li>

-</ul>
-
-
-
-<h2><a name="init"></a>Initializing the Utility Class</h2>
-
-<p class="important"><strong>Important:</strong>&nbsp; In order to initialize the Utility class, your database driver must
-already be running, since the utilities class relies on it.</p>
-
-<p>Load the Utility Class as follows:</p>
-
-<code>$this->load->dbutil()</code>
-
-<p>Once initialized you will access the functions using the <dfn>$this->dbutil</dfn> object:</p>
-
-<code>$this->dbutil->some_function()</code>
-
-<h2><a name="list"></a>$this->dbutil->list_databases()</h2>
-<p>Returns an array of database names:</p>
-
-<code>
-$dbs = $this->dbutil->list_databases();<br />
-<br />
-foreach ($dbs as $db)<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo $db;<br />
-}</code>
-
-
-<h2><a name="exists"></a>$this->dbutil->database_exists();</h2>
-
-<p>Sometimes it's helpful to know whether a particular database exists.
-Returns a boolean TRUE/FALSE.  Usage example:</p>
-
-<code>
-if ($this->dbutil->database_exists('database_name'))<br />
-{<br />
-&nbsp;&nbsp; // some code...<br />
-}
-</code>
-
-<p>Note:  Replace <em>database_name</em> with the name of the table you are looking for. This function is case sensitive.</p>
-
-
-
-<h2><a name="opttb"></a>$this->dbutil->optimize_table('table_name');</h2>
-
-<p class="important"><strong>Note:</strong>&nbsp; This features is only available for MySQL/MySQLi databases.</p>
-
-
-<p>Permits you to optimize a table using the table name specified in the first parameter. Returns TRUE/FALSE based on success or failure:</p>
-
-<code>
-if ($this->dbutil->optimize_table('table_name'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo 'Success!';<br />
-}
-</code>
-
-<p><strong>Note:</strong> Not all database platforms support table optimization.</p>
-
-
-<h2><a name="repair"></a>$this->dbutil->repair_table('table_name');</h2>
-
-<p class="important"><strong>Note:</strong>&nbsp; This features is only available for MySQL/MySQLi databases.</p>
-
-
-<p>Permits you to repair a table using the table name specified in the first parameter. Returns TRUE/FALSE based on success or failure:</p>
-
-<code>
-if ($this->dbutil->repair_table('table_name'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo 'Success!';<br />
-}
-</code>
-
-<p><strong>Note:</strong> Not all database platforms support table repairs.</p>
-
-
-<h2><a name="optdb"></a>$this->dbutil->optimize_database();</h2>
-
-<p class="important"><strong>Note:</strong>&nbsp; This features is only available for MySQL/MySQLi databases.</p>
-
-<p>Permits you to optimize the database your DB class is currently connected to. Returns an array containing the DB status messages or FALSE on failure.</p>
-
-<code>
-$result = $this->dbutil->optimize_database();<br />
-<br />
-if ($result !== FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp; print_r($result);<br />
-}
-</code>
-
-<p><strong>Note:</strong> Not all database platforms support table optimization.</p>
-
-
-<h2><a name="csv"></a>$this->dbutil->csv_from_result($db_result)</h2>
-
-<p>Permits you to generate a CSV file from a query result. The first parameter of the function must contain the result object from your query.
-Example:</p>
-
-<code>
-$this->load->dbutil();<br />
-<br />
-$query = $this->db->query("SELECT * FROM mytable");<br />
-<br />
-echo $this->dbutil->csv_from_result($query);
-</code>
-
-<p>The second, third, and fourth parameters allow you to
-set the delimiter, newline, and enclosure characters respectively.  By default tabs are used as the delimiter, "\n" is used as a new line, and a double-quote is used as the enclosure.  Example:</p>
-
-<code>
-$delimiter = ",";<br />
-$newline = "\r\n";<br />
-$enclosure = '"';<br />
-<br />
-echo $this->dbutil->csv_from_result($query, $delimiter, $newline, $enclosure);
-</code>
-
-<p><strong>Important:</strong>&nbsp; This function will NOT write the CSV file for you.  It simply creates the CSV layout.
-If you need to write the file use the <a href="../helpers/file_helper.html">File Helper</a>.</p>
-
-
-<h2><a name="xml"></a>$this->dbutil->xml_from_result($db_result)</h2>
-
-<p>Permits you to generate an XML file from a query result. The first parameter expects a query result object, the second
-may contain an optional array of config parameters.  Example:</p>
-
-<code>
-$this->load->dbutil();<br />
-<br />
-$query = $this->db->query("SELECT * FROM mytable");<br />
-<br />
-$config = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'root'&nbsp;&nbsp;&nbsp; => 'root',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'element' => 'element', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'newline' => "\n", <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tab'&nbsp;&nbsp;&nbsp;&nbsp;=> "\t"<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo $this->dbutil->xml_from_result($query, $config);
-</code>
-
-<p><strong>Important:</strong>&nbsp; This function will NOT write the XML file for you.  It simply creates the XML layout.
-If you need to write the file use the <a href="../helpers/file_helper.html">File Helper</a>.</p>
-
-
-<h2><a name="backup"></a>$this->dbutil->backup()</h2>
-
-<p>Permits you to backup your full database or individual tables.  The backup data can be compressed in either Zip or Gzip format.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; This features is only available for MySQL databases.</p>
-
-<p>Note: Due to the limited execution time and memory available to PHP, backing up very large
-databases may not be possible.  If your database is very large you might need to backup directly from your SQL server
-via the command line, or have your server admin do it for you if you do not have root privileges.</p>
-
-<h3>Usage Example</h3>
-
-<code>
-<dfn>// Load the DB utility class</dfn><br />
-$this->load->dbutil();<br /><br />
-
-<dfn>// Backup your entire database and assign it to a variable</dfn><br />
-$backup =& $this->dbutil->backup();
-
-<br /><br />
-<dfn>// Load the file helper and write the file to your server</dfn><br />
-$this->load->helper('file');<br />
-write_file('/path/to/mybackup.gz', $backup);
-
-<br /><br />
-<dfn>// Load the download helper and send the file to your desktop</dfn><br />
-$this->load->helper('download');<br />
-force_download('mybackup.gz', $backup);
-</code>
-
-<h3>Setting Backup Preferences</h3>
-
-<p>Backup preferences are set by submitting an array of values to the first parameter of the backup function. Example:</p>
-
-<code>$prefs = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tables'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> array('table1', 'table2'),&nbsp;&nbsp;// Array of tables to backup.<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ignore'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> array(),&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// List of tables to omit from the backup<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'format'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'txt',&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// gzip, zip, txt<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mybackup.sql',&nbsp;&nbsp;&nbsp;&nbsp;// File name - NEEDED ONLY WITH ZIP FILES<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'add_drop'&nbsp;&nbsp;&nbsp;&nbsp;=> TRUE,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Whether to add DROP TABLE statements to backup file<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'add_insert'&nbsp;&nbsp;=> TRUE,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Whether to add INSERT data to backup file<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'newline'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> "\n"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Newline character used in backup file<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->dbutil->backup($prefs);
-</code>

-<h1>Alternate PHP Syntax for View Files</h1>
-
-<p>If you do not utilize CodeIgniter's <a href="../libraries/parser.html">template engine</a>, you'll be using pure PHP
-in your View files.  To minimize the PHP code in these files, and to make it easier to identify the code blocks it is recommended that you use
-PHPs alternative syntax for control structures and short tag echo statements.  If you are not familiar with this syntax, it allows you to eliminate the braces from your code,
-and eliminate "echo" statements.</p>
-
-<h2>Automatic Short Tag Support</h2>
-
-<p><strong>Note:</strong> If you find that the syntax described in this page does not work on your server it might
-be that "short tags" are disabled in your PHP ini file. CodeIgniter will optionally rewrite short tags on-the-fly,
-allowing you to use that syntax even if your server doesn't support it.  This feature can be enabled in your
-<dfn>config/config.php</dfn> file.</p>
-
-<p class="important">Please note that if you do use this feature, if PHP errors are encountered
-in your <strong>view files</strong>, the error message and line number will not be accurately shown.  Instead, all errors
-will be shown as <kbd>eval()</kbd> errors.</p>
-
-
-<h2>Alternative Echos</h2>
-
-<p>Normally to echo, or print out a variable you would do this:</p>
-
-<code>&lt;?php echo $variable; ?></code>
-
-<p>With the alternative syntax you can instead do it this way:</p>
-
-<code>&lt;?=$variable?></code>
-
-
-
-<h2>Alternative Control Structures</h2>
-
-<p>Controls structures, like <var>if</var>, <var>for</var>, <var>foreach</var>, and <var>while</var> can be
-written in a simplified format as well.  Here is an example using foreach:</p>
-
-<code>
-&lt;ul><br />
-<br />
-<var>&lt;?php foreach ($todo as $item): ?></var><br />
-<br />
-&lt;li><var>&lt;?=$item?></var>&lt;/li><br />
-<br />
-<var>&lt;?php endforeach; ?></var><br />
-<br />
-&lt;/ul></code>
-
-<p>Notice that there are no braces.  Instead, the end brace is replaced with <var>endforeach</var>.
-Each of the control structures listed above has a similar closing syntax:
-<var>endif</var>, <var>endfor</var>, <var>endforeach</var>, and <var>endwhile</var></p>
-
-<p>Also notice that instead of using a semicolon after each structure (except the last one), there is a colon.  This is
-important!</p>
-
-<p>Here is another example, using if/elseif/else.  Notice the colons:</p>
-
-
-<code><var>&lt;?php if ($username == 'sally'): ?></var><br />
-<br />
-&nbsp;&nbsp;&nbsp;&lt;h3>Hi Sally&lt;/h3><br />
-<br />
-<var>&lt;?php elseif ($username == 'joe'): ?></var><br />
-<br />
-&nbsp;&nbsp;&nbsp;&lt;h3>Hi Joe&lt;/h3><br />
-<br />
-<var>&lt;?php else: ?></var><br />
-<br />
-&nbsp;&nbsp;&nbsp;&lt;h3>Hi unknown user&lt;/h3><br />
-<br />
-<var>&lt;?php endif; ?></var></code>

-<h1>Creating Ancillary Classes</h1>
-
-<p>In some cases you may want to develop classes that exist apart from your controllers but have the ability to
-utilize all of CodeIgniter's resources. This is easily possible as you'll see.</p>
-
-<h2>get_instance()</h2>
-
-
-<p><strong>Any class that you instantiate within your controller functions can access CodeIgniter's native resources</strong> simply by using the <kbd>get_instance()</kbd> function.
-This function returns the main CodeIgniter object.</p>
-
-<p>Normally, to call any of the available CodeIgniter functions requires you to use the <kbd>$this</kbd> construct:</p>
-
-<code>
-<strong>$this</strong>->load->helper('url');<br />
-<strong>$this</strong>->load->library('session');<br />
-<strong>$this</strong>->config->item('base_url');<br />
-etc.
-</code>
-
-<p><kbd>$this</kbd>, however, only works within your controllers, your models, or your views.
-If you would like to use CodeIgniter's classes from within your own custom classes you can do so as follows:</p>
-
-
-<p>First, assign the CodeIgniter object to a variable:</p>
-
-<code>$CI =& get_instance();</code>
-
-<p>Once you've assigned the object to a variable, you'll use that variable <em>instead</em> of <kbd>$this</kbd>:</p>
-
-<code>
-$CI =& get_instance();<br /><br />
-$CI->load->helper('url');<br />
-$CI->load->library('session');<br />
-$CI->config->item('base_url');<br />
-etc.
-</code>
-
-<p class="important"><strong>Note:</strong> You'll notice that the above get_instance() function is being passed by reference:
-<br /><br />
-<var>$CI =& get_instance();</var>
-<br /><br />
-This is very important. Assigning by reference allows you to use the original CodeIgniter object rather than creating a copy of it.</p>

-<h1>Auto-loading Resources</h1>
-
-<p>CodeIgniter comes with an "Auto-load" feature that permits libraries, helpers, and models to be initialized
-automatically every time the system runs. If you need certain resources globally throughout your application you should
-consider auto-loading them for convenience.</p>
-
-<p>The following items can be loaded automatically:</p>
-
-<ul>
-<li>Core classes found in the "libraries" folder</li>
-<li>Helper files found in the "helpers" folder</li>
-<li>Custom config files found in the "config" folder</li>
-<li>Language files found in the "system/language" folder </li>
-<li>Models found in the &quot;models&quot; folder</li>
-</ul>
-
-<p>To autoload resources, open the <var>application/config/autoload.php</var> file and add the item you want
-loaded to the <samp>autoload</samp> array. You'll find instructions in that file corresponding to each
-type of item.</p>
-
-<p class="important"><strong>Note:</strong>  Do not include the file extension (.php) when adding items to the autoload array.</p>

-<h1>Web Page Caching</h1>
-
-<p>CodeIgniter lets you cache your pages in order to achieve maximum performance.</p>
-
-<p>Although CodeIgniter is quite fast, the amount of dynamic information you display in your pages will correlate directly to the
-server resources, memory, and processing cycles utilized, which affect your page load speeds.
-By caching your pages, since they are saved in their fully rendered state, you can achieve performance that nears that of static web pages.</p>
-
-
-<h2>How Does Caching Work?</h2>
-
-<p>Caching can be enabled on a per-page basis, and you can set the length of time that a page should remain cached before being refreshed.
-When a page is loaded for the first time, the cache file will be written to your <dfn>application/cache</dfn> folder.  On subsequent page loads the cache file will be retrieved
-and sent to the requesting user's browser.  If it has expired, it will be deleted and refreshed before being sent to the browser.</p>
-
-<p>Note: The Benchmark tag is not cached so you can still view your page load speed when caching is enabled.</p>
-
-<h2>Enabling Caching</h2>
-
-<p>To enable caching, put the following tag in any of your controller functions:</p>
-
-<code>$this->output->cache(<var>n</var>);</code>
-
-<p>Where <var>n</var> is the number of <strong>minutes</strong> you wish the page to remain cached between refreshes.</p>
-
-<p>The above tag can go anywhere within a function. It is not affected by the order that it appears, so place it wherever it seems
-most logical to you. Once the tag is in place, your pages will begin being cached.</p>
-
-<p class="important"><strong>Warning:</strong> Because of the way CodeIgniter stores content for output, caching will only work if you are generating display for your controller with a <a href="./views.html">view</a>.</p>
-<p class="important"><strong>Note:</strong> Before the cache files can be written you must set the file permissions on your
-<dfn>application/cache</dfn> folder such that it is writable.</p>
-
-<h2>Deleting Caches</h2>
-
-<p>If you no longer wish to cache a file you can remove the caching tag and it will no longer be refreshed when it expires.  Note:
-Removing the tag will not delete the cache immediately.  It will have to expire normally.  If you need to remove it earlier you
-will need to manually delete it from your cache folder.</p>

-<h1>Running via the CLI</h1>
-
-<p>
-	As well as calling an applications <a href="./controllers.html">Controllers</a> via the URL in a browser they can also be loaded via the command-line interface (CLI).
-</p>
-
-
-<ul>
-<li><a href="#what">What is the CLI?</a></li>
-<li><a href="#why">Why use this method?</a></li>
-<li><a href="#how">How does it work?</a></li>
-</ul>
-
-
-<a name="what"></a>
-<h2>What is the CLI?</h2>
-
-<p><dfn>The command-line interface is a text-based method of interacting with computers.</dfn> For more information, check the <a href="http://en.wikipedia.org/wiki/Command-line_interface">Wikipedia article</a>.</p>
-
-<a name="why"></a>
-
-<h2>Why run via the command-line?</h2>
-
-<p>
-	There are many reasons for running CodeIgniter from the command-line, but they are not always obvious.</p>
-
-<ul>
-	<li>Run your cron-jobs without needing to use wget or curl</li>
-	<li>Make your cron-jobs inaccessible from being loaded in the URL by checking for <kbd>$this->input->is_cli_request()</kbd></li>
-	<li>Make interactive "tasks" that can do things like set permissions, prune cache folders, run backups, etc.</li>
-	<li>Integrate with other applications in other languages. For example, a random C++ script could call one command and run code in your models!</li>
-</ul>
-
-<a name="how"></a>
-<h2>Let's try it:&nbsp; Hello World!</h2>
-
-<p>Let's create a simple controller so you can see it in action. Using your text editor, create a file called <dfn>tools.php</dfn>, and put the following code in it:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;?php
-class Tools extends CI_Controller {
-
-	public function message($to = 'World')
-	{
-		echo "Hello {$to}!".PHP_EOL;
-	}
-}
-?&gt;
-</textarea>
-
-<p>Then save the file to your <dfn>application/controllers/</dfn> folder.</p>
-
-<p>Now normally you would visit the your site using a URL similar to this:</p>
-
-<code>example.com/index.php/<var>tools</var>/<var>message</var>/<var>to</var></code>
-
-<p>Instead, we are going to open Terminal in Mac/Lunix or go to Run > "cmd" in Windows and navigate to our CodeIgniter project.</p>
-
-<blockquote>
-	$ cd /path/to/project;<br />
-	$ php index.php tools message
-</blockquote>
-
-<p>If you did it right, you should see <samp>Hello World!</samp>.</p>
-
-<blockquote>
-	$ php index.php tools message "John Smith"
-</blockquote>
-
-<p>Here we are passing it a argument in the same way that URL parameters work. "John Smith" is passed as a argument and output is: <samp>Hello John Smith!</samp>.</p>
-
-<h2>That's it!</h2>
-
-<p>That, in a nutshell, is all there is to know about controllers on the command line. Remember that this is just a normal controller, so routing and _remap works fine.</p>

-<h1>Common Functions</h1>
-
-<p>CodeIgniter uses a few functions for its operation that are globally defined, and are available to you at any point. These do not require loading any libraries or helpers.</p>
-
-<h2>is_php('<var>version_number</var>')</h2>
-
-<p>is_php() determines of the PHP version being used is greater than the supplied <var>version_number</var>.</p>
-
-<code>if (is_php('5.3.0'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$str = quoted_printable_encode($str);<br />
-}</code>
-
-<p>Returns boolean <kbd>TRUE</kbd> if the installed version of PHP is equal to or greater than the supplied version number.  Returns  <kbd>FALSE</kbd> if the installed version of PHP is lower than the supplied version number.</p>
-
-
-<h2>is_really_writable('<var>path/to/file</var>')</h2>
-
-<p>is_writable() returns TRUE on Windows servers when you really can't write to the file as the OS reports to PHP as FALSE only if the read-only attribute is marked. This function determines if a file is actually writable by attempting to write to it first. Generally only recommended on platforms where this information may be unreliable.</p>
-
-<code>if (is_really_writable('file.txt'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo &quot;I could write to this if I wanted to&quot;;<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo &quot;File is not writable&quot;;<br />
-}</code>
-
-<h2>config_item('<var>item_key</var>')</h2>
-<p>The <a href="../libraries/config.html">Config library</a> is the preferred way of accessing configuration information, however config_item() can be used to retrieve single keys. See Config library documentation for more information.</p>
-
-<h2>show_error('<var>message</var>'), show_404('<var>page</var>'), log_message('<var>level</var>', '<samp>message</samp>')</h2>
-<p>These are each outlined on the <a href="errors.html">Error Handling</a> page.</p>
-
-<h2>set_status_header(<var>code</var>, '<var>text</var>');</h2>
-
-<p>Permits you to manually set a server status header.  Example:</p>
-
-<code>set_status_header(401);<br />
-// Sets the header as:  Unauthorized</code>
-
-<p><a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html">See here</a> for a full list of headers.</p>
-
-
-<h2>remove_invisible_characters(<var>$str</var>)</h2>
-<p>This function prevents inserting null characters between ascii characters, like Java\0script.</p>
-
-
-<h2>html_escape(<var>$mixed</var>)</h2>
-<p>This function provides short cut for htmlspecialchars() function. It accepts string and array. To prevent Cross Site Scripting (XSS), it is very useful.</p>

-<h2>What is a Controller?</h2>
-
-<p><dfn>A Controller is simply a class file that is named in a way that can be associated with a URI.</dfn></p>
-
-<p>Consider this URI:</p>
-
-<code>example.com/index.php/<var>blog</var>/</code>
-
-<p>In the above example, CodeIgniter would attempt to find a controller named <dfn>blog.php</dfn> and load it.</p>
-
-<p><strong>When a controller's name matches the first segment of a URI, it will be loaded.</strong></p>
-
-<a name="hello"></a>
-<h2>Let's try it:&nbsp; Hello World!</h2>
-
-<p>Let's create a simple controller so you can see it in action.  Using your text editor, create a file called <dfn>blog.php</dfn>, and put the following code in it:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;?php
-class Blog extends CI_Controller {
-
-	public function index()
-	{
-		echo 'Hello World!';
-	}
-}
-?&gt;
-</textarea>
-
-
-
-<p>Then save the file to your <dfn>application/controllers/</dfn> folder.</p>
-
-<p>Now visit the your site using a URL similar to this:</p>
-
-<code>example.com/index.php/<var>blog</var>/</code>
-
-<p>If you did it right, you should see <samp>Hello World!</samp>.</p>
-
-<p>Note: Class names must start with an uppercase letter.  In other words, this is valid:</p>
-
-<code>&lt;?php<br />
-class <var>Blog</var> extends CI_Controller {<br />
-<br />
-}<br />
-?&gt;</code>
-
-<p>This is <strong>not</strong> valid:</p>
-
-<code>&lt;?php<br />
-class <var>blog</var> extends CI_Controller {<br />
-<br />
-}<br />
-?&gt;</code>
-
-<p>Also, always make sure your controller <dfn>extends</dfn> the parent controller class so that it can inherit all its functions.</p>
-
-
-
-<a name="functions"></a>
-<h2>Functions</h2>
-
-<p>In the above example the function name is <dfn>index()</dfn>.  The "index" function is always loaded by default if the
-<strong>second segment</strong> of the URI is empty.  Another way to show your "Hello World" message would be this:</p>
-
-<code>example.com/index.php/<var>blog</var>/<samp>index</samp>/</code>
-
-<p><strong>The second segment of the URI determines which function in the controller gets called.</strong></p>
-
-<p>Let's try it.  Add a new function to your controller:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="15">
-&lt;?php
-class Blog extends CI_Controller {
-
-	public function index()
-	{
-		echo 'Hello World!';
-	}
-
-	public function comments()
-	{
-		echo 'Look at this!';
-	}
-}
-?&gt;
-</textarea>
-
-<p>Now load the following URL to see the <dfn>comment</dfn> function:</p>
-
-<code>example.com/index.php/<var>blog</var>/<samp>comments</samp>/</code>
-
-<p>You should see your new message.</p>
-
-<a name="passinguri"></a>
-<h2>Passing URI Segments to your Functions</h2>
-
-<p>If your URI contains more then two segments they will be passed to your function as parameters.</p>
-
-<p>For example, lets say you have a URI like this:</p>
-
-<code>example.com/index.php/<var>products</var>/<samp>shoes</samp>/<kbd>sandals</kbd>/<dfn>123</dfn></code>
-
-<p>Your function will be passed URI segments 3 and 4 ("sandals" and "123"):</p>
-
-<code>
-&lt;?php<br />
-class Products extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;public function shoes($sandals, $id)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $sandals;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $id;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}<br />
-?&gt;
-</code>
-
-<p class="important"><strong>Important:</strong>&nbsp; If you are using the <a href="routing.html">URI Routing</a> feature, the segments
-passed to your function will be the re-routed ones.</p>
-
-
-<a name="default"></a>
-<h2>Defining a Default Controller</h2>
-
-<p>CodeIgniter can be told to load a default controller when a URI is not present,
-as will be the case when only your site root URL is requested.  To specify a default controller, open
-your <dfn>application/config/routes.php</dfn> file and set this variable:</p>
-
-<code>$route['default_controller'] = '<var>Blog</var>';</code>
-
-<p>Where <var>Blog</var> is the name of the controller class you want used. If you now load your main index.php file without
-specifying any URI segments you'll see your Hello World message by default.</p>
-
-
-
-<a name="remapping"></a>
-<h2>Remapping Function Calls</h2>
-
-<p>As noted above, the second segment of the URI typically determines which function in the controller gets called.
-CodeIgniter permits you to override this behavior through the use of the <kbd>_remap()</kbd> function:</p>
-
-<code>public function _remap()<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;// Some code here...<br />
-}</code>
-
-<p class="important"><strong>Important:</strong>&nbsp; If your controller contains a function named <kbd>_remap()</kbd>, it will <strong>always</strong>
-get called regardless of what your URI contains.  It overrides the normal behavior in which the URI determines which function is called,
-allowing you to define your own function routing rules.</p>
-
-<p>The overridden function call (typically the second segment of the URI) will be passed as a parameter to the <kbd>_remap()</kbd> function:</p>
-
-<code>public function _remap(<var>$method</var>)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;if ($method == 'some_method')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->$method();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;else<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->default_method();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<p>Any extra segments after the method name are passed into <kbd>_remap()</kbd> as an optional second parameter. This array can be used in combination with PHP's <a href="http://php.net/call_user_func_array">call_user_func_array</a> to emulate CodeIgniter's default behavior.</p>
-
-<code>public function _remap($method, $params = array())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$method = 'process_'.$method;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;if (method_exists($this, $method))<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return call_user_func_array(array($this, $method), $params);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />

-<a name="output"></a>
-<h2>Processing Output</h2>
-
-<p>CodeIgniter has an output class that takes care of sending your final rendered data to the web browser automatically.  More information on this can be found in the
-<a href="views.html">Views</a> and <a href="../libraries/output.html">Output class</a> pages.  In some cases, however, you might want to
-post-process the finalized data in some way and send it to the browser yourself.  CodeIgniter permits you to
-add a function named <dfn>_output()</dfn> to your controller that will receive the finalized output data.</p>
-
-<p><strong>Important:</strong>&nbsp; If your controller contains a function named <kbd>_output()</kbd>, it will <strong>always</strong>
-be called by the output class instead of echoing the finalized data directly. The first parameter of the function will contain the finalized output.</p>
-
-<p>Here is an example:</p>
-
-<code>
-public function _output($output)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $output;<br />
-}</code>
-
-<p class="important">Please note that your <dfn>_output()</dfn> function will receive the data in its finalized state.  Benchmark and memory usage data will be rendered,
-cache files written (if you have caching enabled), and headers will be sent (if you use that <a href="../libraries/output.html">feature</a>)
-before it is handed off to the _output() function.<br />
-<br />
-To have your controller's output cached properly, its <dfn>_output()</dfn> method can use:<br />
-
-<code>if ($this-&gt;output-&gt;cache_expiration &gt; 0)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;output-&gt;_write_cache($output);<br />
-}</code>
-
-If you are using this feature the page execution timer and memory usage stats might not be perfectly accurate
-since they will not take into acccount any further processing you do.  For an alternate way to control output <em>before</em> any of the final processing is done, please see
-the available methods in the <a href="../libraries/output.html">Output Class</a>.</p>
-
-<a name="private"></a>
-<h2>Private Functions</h2>
-
-
-<p>In some cases you may want certain functions hidden from public access.  To make a function private, simply add an
-underscore as the name prefix and it will not be served via a URL request. For example, if you were to have a function like this:</p>
-
-<code>
-private function _utility()<br />
-{<br />
-&nbsp;&nbsp;// some code<br />
-}</code>
-
-<p>Trying to access it via the URL, like this, will not work:</p>
-
-<code>example.com/index.php/<var>blog</var>/<samp>_utility</samp>/</code>
-
-
-
-<a name="subfolders"></a>
-<h2>Organizing Your Controllers into Sub-folders</h2>
-
-<p>If you are building a large application you might find it convenient to organize your controllers into sub-folders.  CodeIgniter permits you to do this.</p>
-
-<p>Simply create folders within your <dfn>application/controllers</dfn> directory and place your controller classes within them.</p>
-
-<p><strong>Note:</strong>&nbsp; When using this feature the first segment of your URI must specify the folder.  For example, lets say you have a controller
-located here:</p>
-
-<code>application/controllers/<kbd>products</kbd>/shoes.php</code>
-
-<p>To call the above controller your URI will look something like this:</p>
-
-<code>example.com/index.php/products/shoes/show/123</code>
-
-<p>Each of your sub-folders may contain a default controller which will be
-called if the URL contains only the sub-folder.  Simply name your default controller as specified in your
-<dfn>application/config/routes.php</dfn> file</p>
-
-
-<p>CodeIgniter also permits you to remap your URIs using its <a href="routing.html">URI Routing</a> feature.</p>
-
-
-<h2><a name="constructors"></a>Class Constructors</h2>
-
-
-<p>If you intend to use a constructor in any of your Controllers, you <strong>MUST</strong> place the following line of code in it:</p>
-
-<code>parent::__construct();</code>
-
-<p>The reason this line is necessary is because your local constructor will be overriding the one in the parent controller class so we need to manually call it.</p>
-
-<code>
-&lt;?php<br />
-class <kbd>Blog</kbd> extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;public function <kbd>__construct()</kbd><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<var>parent::__construct();</var><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Your own constructor code<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}<br />
-?&gt;</code>
-
-<p>Constructors are useful if you need to set some default values, or run a default process when your class is instantiated.
-Constructors can't return a value, but they can do some default work.</p>
-
-<a name="reserved"></a>
-<h2>Reserved Function Names</h2>
-
-<p>Since your controller classes will extend the main application controller you
-must be careful not to name your functions identically to the ones used by that class, otherwise your local functions
-will override them. See <a href="reserved_names.html">Reserved Names</a> for a full list.</p>
-
-<h2>That's it!</h2>
-
-<p>That, in a nutshell, is all there is to know about controllers.</p>

-<h1>Creating Core System Classes</h1>
-
-<p>Every time CodeIgniter runs there are several base classes that are initialized automatically as part of the core framework.
-It is possible, however, to swap any of the core system classes with your own versions or even extend the core versions.</p>
-
-<p><strong>Most users will never have any need to do this,
-but the option to replace or extend them does exist for those who would like to significantly alter the CodeIgniter core.</strong>
-</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; Messing with a core system class has a lot of implications, so make sure you
-know what you are doing before attempting it.</p>
-
-
-<h2>System Class List</h2>
-
-<p>The following is a list of the core system files that are invoked every time CodeIgniter runs:</p>
-
-<ul>
-<li>Benchmark</li>
-<li>Config</li>
-<li>Controller</li>
-<li>Exceptions</li>
-<li>Hooks</li>
-<li>Input</li>
-<li>Language</li>
-<li>Loader</li>
-<li>Log</li>
-<li>Output</li>
-<li>Router</li>
-<li>URI</li>
-<li>Utf8</li>
-</ul>
-
-<h2>Replacing Core Classes</h2>
-
-<p>To use one of your own system classes instead of a default one simply place your version inside your local <dfn>application/core</dfn> directory:</p>
-
-<code>application/core/<dfn>some-class.php</dfn></code>
-
-<p>If this directory does not exist you can create it.</p>
-
-<p>Any file named identically to one from the list above will be used instead of the one normally used.</p>
-
-<p>Please note that your class must use <kbd>CI</kbd> as a prefix. For example, if your file is named <kbd>Input.php</kbd> the class will be named:</p>
-
-<code>
-class CI_Input {<br /><br />
-
-}
-</code>
-
-
-
-<h2>Extending Core Class</h2>
-
-<p>If all you need to do is add some functionality to an existing library - perhaps add a function or two - then
-it's overkill to replace the entire library with your version.  In this case it's better to simply extend the class.
-Extending a class is nearly identical to replacing a class with a couple exceptions:</p>
-
-<ul>
-<li>The class declaration must extend the parent class.</li>
-<li>Your new class name and filename must be prefixed with <kbd>MY_</kbd> (this item is configurable.  See below.).</li>
-</ul>
-
-<p>For example, to extend the native <kbd>Input</kbd> class you'll create a file named <dfn>application/core/</dfn><kbd>MY_Input.php</kbd>, and declare your class with:</p>
-
-<code>
-class MY_Input extends CI_Input {<br /><br />
-
-}</code>
-
-<p>Note: If you need to use a constructor in your class make sure you extend the parent constructor:</p>
-
-<code>
-class MY_Input extends CI_Input {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function __construct()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<p class="important"><strong>Tip:</strong>&nbsp; Any functions in your class that are named identically to the functions in the parent class will be used instead of the native ones
-(this is known as "method overriding").
-This allows you to substantially alter the CodeIgniter core.</p>
-
-<p>If you are extending the Controller core class, then be sure to extend your new class in your application controller's constructors.</p>
-
-<code>class Welcome extends MY_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function __construct()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function index()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('welcome_message');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<h3>Setting Your Own Prefix</h3>
-
-<p>To set your own sub-class prefix, open your <dfn>application/config/config.php</dfn> file and look for this item:</p>
-
-<code>$config['subclass_prefix'] = 'MY_';</code>
-
-<p>Please note that all native CodeIgniter libraries are prefixed with <kbd>CI_</kbd> so DO NOT use that as your prefix.</p>

-<h1>Creating Libraries</h1>
-
-<p>When we use the term "Libraries" we are normally referring to the classes that are located in the <kbd>libraries</kbd>
-directory and described in the Class Reference of this user guide.  In this case, however, we will instead describe how you can create
-your own libraries within your <dfn>application/libraries</dfn> directory in order to maintain separation between your local resources
-and the global framework resources.</p>
-
-<p>As an added bonus, CodeIgniter permits your libraries to <kbd>extend</kbd> native classes if you simply need to add some functionality
-to an existing library. Or you can even replace native libraries just by placing identically named versions in your <dfn>application/libraries</dfn> folder.</p>
-
-<p>In summary:</p>
-
-<ul>
-<li>You can create entirely new libraries.</li>
-<li>You can extend native libraries.</li>
-<li>You can replace native libraries.</li>
-</ul>
-
-<p>The page below explains these three concepts in detail.</p>
-
-<p class="important"><strong>Note:</strong> The Database classes can not be extended or replaced with your own classes.  All other classes are able to be replaced/extended.</p>
-
-
-<h2>Storage</h2>
-
-<p>Your library classes should be placed within your <dfn>application/libraries</dfn> folder, as this is where CodeIgniter will look for them when
-they are initialized.</p>
-
-
-<h2>Naming Conventions</h2>
-
-<ul>
-<li>File names must be capitalized. For example:&nbsp; <dfn>Myclass.php</dfn></li>
-<li>Class declarations must be capitalized. For example:&nbsp;  <kbd>class Myclass</kbd></li>
-<li>Class names and file names must match.</li>
-</ul>
-
-
-<h2>The Class File</h2>
-
-<p>Classes should have this basic prototype (Note:  We are using the name <kbd>Someclass</kbd> purely as an example):</p>
-
-<code>&lt;?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
-<br /><br />
-class Someclass {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;public function some_function()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}<br /><br />
-/* End of file Someclass.php */</code>
-
-
-<h2>Using Your Class</h2>
-
-<p>From within any of your <a href="controllers.html">Controller</a> functions you can initialize your class using the standard:</p>
-
-<code>$this->load->library('<kbd>someclass</kbd>');</code>
-
-<p>Where <em>someclass</em> is the file name, without the ".php" file extension. You can submit the file name capitalized or lower case.
-CodeIgniter doesn't care.</p>
-
-<p>Once loaded you can access your class using the <kbd>lower case</kbd> version:</p>
-
-<code>$this-><kbd>someclass</kbd>->some_function();&nbsp; // Object instances will always be lower case
-</code>
-
-
-
-<h2>Passing Parameters When Initializing Your Class</h2>
-
-<p>In the library loading function you can dynamically pass data as an array via the second parameter and it will be passed to your class
-constructor:</p>
-
-<code>
-$params = array('type' => 'large', 'color' => 'red');<br />
-<br />
-$this->load->library('Someclass', <kbd>$params</kbd>);</code>
-
-<p>If you use this feature you must set up your class constructor to expect data:</p>
-
-<code>&lt;?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');<br />
-<br />
-class Someclass {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;public function __construct($params)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Do something with $params<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}<br /><br />
-?&gt;</code>
-
-<p class="important">You can also pass parameters stored in a config file.  Simply create a config file named identically to the class <kbd>file name</kbd>
-and store it in your <dfn>application/config/</dfn> folder.  Note that if you dynamically pass parameters as described above,
-the config file option will not be available.</p>
-
-
-
-
-
-
-
-<h2>Utilizing CodeIgniter Resources within Your Library</h2>
-
-
-<p>To access CodeIgniter's native resources within your library use the <kbd>get_instance()</kbd> function.
-This function returns the CodeIgniter super object.</p>
-
-<p>Normally from within your controller functions you will call any of the available CodeIgniter functions using the <kbd>$this</kbd> construct:</p>
-
-<code>
-<strong>$this</strong>->load->helper('url');<br />
-<strong>$this</strong>->load->library('session');<br />
-<strong>$this</strong>->config->item('base_url');<br />
-etc.
-</code>
-
-<p><kbd>$this</kbd>, however, only works directly within your controllers, your models, or your views.
-If you would like to use CodeIgniter's classes from within your own custom classes you can do so as follows:</p>
-
-
-<p>First, assign the CodeIgniter object to a variable:</p>
-
-<code>$CI =&amp; get_instance();</code>
-
-<p>Once you've assigned the object to a variable, you'll use that variable <em>instead</em> of <kbd>$this</kbd>:</p>
-
-<code>
-$CI =&amp; get_instance();<br />
-<br />
-$CI->load->helper('url');<br />
-$CI->load->library('session');<br />
-$CI->config->item('base_url');<br />
-etc.
-</code>
-
-<p class="important"><strong>Note:</strong> You'll notice that the above get_instance() function is being passed by reference:
-<br /><br />
-<var>$CI =&amp; get_instance();</var>
-<br />
-<br />
-<kbd>This is very important.</kbd> Assigning by reference allows you to use the original CodeIgniter object rather than creating a copy of it.</p>
-
-
-<h2>Replacing Native Libraries with Your Versions</h2>
-
-<p>Simply by naming your class files identically to a native library will cause CodeIgniter to use it instead of the native one. To use this
-feature you must name the file and the class declaration exactly the same as the native library.  For example, to replace the native <kbd>Email</kbd> library
-you'll create a file named <dfn>application/libraries/Email.php</dfn>, and declare your class with:</p>
-
-<code>
-class CI_Email {<br /><br />
-
-}</code>
-
-<p>Note that most native classes are prefixed with <kbd>CI_</kbd>.</p>
-
-<p>To load your library you'll see the standard loading function:</p>
-
-<code>$this->load->library('<kbd>email</kbd>');</code>
-
-<p class="important"><strong>Note:</strong> At this time the Database classes can not be replaced with your own versions.</p>
-
-
-<h2>Extending Native Libraries</h2>
-
-<p>If all you need to do is add some functionality to an existing library - perhaps add a function or two - then
-it's overkill to replace the entire library with your version.  In this case it's better to simply extend the class.
-Extending a class is nearly identical to replacing a class with a couple exceptions:</p>
-
-<ul>
-<li>The class declaration must extend the parent class.</li>
-<li>Your new class name and filename must be prefixed with <kbd>MY_</kbd> (this item is configurable.  See below.).</li>
-</ul>
-
-<p>For example, to extend the native <kbd>Email</kbd> class you'll create a file named <dfn>application/libraries/</dfn><kbd>MY_Email.php</kbd>, and declare your class with:</p>
-
-<code>
-class MY_Email extends CI_Email {<br /><br />
-
-}</code>
-
-<p>Note: If you need to use a constructor in your class make sure you extend the parent constructor:</p>
-
-
-<code>
-class MY_Email extends CI_Email {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;public function __construct()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-
-<h3>Loading Your Sub-class</h3>
-
-<p>To load your sub-class you'll use the standard syntax normally used.  DO NOT include your prefix.  For example,
-to load the example above, which extends the Email class, you will use:</p>
-
-<code>$this->load->library('<kbd>email</kbd>');</code>
-
-<p>Once loaded you will use the class variable as you normally would for the class you are extending.  In the case of
-the email class all calls will use:</p>
-
-
-<code>$this-><kbd>email</kbd>->some_function();</code>
-
-
-<h3>Setting Your Own Prefix</h3>
-
-<p>To set your own sub-class prefix, open your <dfn>application/config/config.php</dfn> file and look for this item:</p>
-
-<code>$config['subclass_prefix'] = 'MY_';</code>
-
-<p>Please note that all native CodeIgniter libraries are prefixed with <kbd>CI_</kbd> so DO NOT use that as your prefix.</p>

-<h1>Credits</h1>
-
-<p>CodeIgniter was originally developed by <a href="http://www.ellislab.com/">Rick Ellis</a> (CEO of
-<a href="http://ellislab.com/">EllisLab, Inc.</a>).  The framework was written for performance in the real
-world, with many of the class libraries, helpers, and sub-systems borrowed from the code-base of
-<a href="http://www.expressionengine.com/">ExpressionEngine</a>.</p>
-
-<p>It is currently developed and maintained by the ExpressionEngine Development Team.<br />
-Bleeding edge development is spearheaded by the handpicked contributors of the Reactor Team.</p>
-
-<p>A hat tip goes to Ruby on Rails for inspiring us to create a PHP framework, and for
-bringing frameworks into the general consciousness of the web community.</p>

-<h1>Using CodeIgniter Drivers</h1>
-
-
-<p>Drivers are a special type of Library that has a parent class and any number of potential child classes.  Child classes have access to the parent class, but not their siblings.  Drivers provide an elegant syntax  in your <a href="controllers.html">controllers</a> for libraries that benefit from or require being broken down into discrete classes.</p>
-
-<p>Drivers are found in the <dfn>system/libraries</dfn> folder, in their own folder which is identically named to the parent library class.  Also inside that folder is a subfolder named <kbd>drivers</kbd>, which contains all of the possible child class files.</p>
-
-<p>To use a driver you will initialize it within a controller using the following initialization function:</p>
-
-<code>$this->load->driver('<var>class name</var>'); </code>
-
-<p>Where <var>class name</var> is the name of the driver class you want to invoke.  For example, to load a driver named "Some Parent" you would do this:</p>
-
-<code>$this->load->driver('<var>some_parent</var>');</code>
-
-<p>Methods of that class can then be invoked with:</p>
-
-<code>$this->some_parent->some_method();</code>
-
-<p>The child classes, the drivers themselves, can then be called directly through the parent class, without initializing them:</p>
-
-<code>$this->some_parent->child_one->some_method();<br />
-$this->some_parent->child_two->another_method();</code>
-
-<h2>Creating Your Own Drivers</h2>

-<h1>Handling Multiple Environments</h1>
-
-<p>
-    Developers often desire different system behavior depending on whether
-    an application is running in a development or production
-    environment. For example, verbose error output is something that would
-    be useful while developing an application, but it may also pose a security issue when "live".
-</p>
-
-<h2>The ENVIRONMENT Constant</h2>
-
-<p>
-    By default, CodeIgniter comes with the environment constant set to
-    '<kbd>development</kbd>'. At the top of index.php, you will see:
-</p>
-
-<code>
-define('<var>ENVIRONMENT</var>', '<var>development</var>');
-</code>
-
-<p>
-    In addition to affecting some basic framework behavior (see the next section),
-    you may use this constant in your own development to differentiate
-    between which environment you are running in.
-</p>
-
-<h2>Effects On Default Framework Behavior</h2>
-
-<p>
-    There are some places in the CodeIgniter system where the <kbd>ENVIRONMENT</kbd>
-    constant is used. This section describes how default framework behavior is
-    affected.
-</p>
-
-<h3>Error Reporting</h3>
-
-<p>
-    Setting the <kbd>ENVIRONMENT</kbd> constant to a value of '<kbd>development</kbd>' will
-    cause all PHP errors to be rendered to the browser when they occur. Conversely,
-    setting the constant to '<kbd>production</kbd>' will disable all error output. Disabling
-    error reporting in production is a <a href="security.html">good security practice</a>.
-</p>
-
-<h3>Configuration Files</h3>
-
-<p>
-    Optionally, you can have CodeIgniter load environment-specific
-    configuration files. This may be useful for managing things like differing API keys
-    across multiple environments. This is described in more detail in the
-    environment section of the <a href="../libraries/config.html#environments">Config Class</a> documentation.

-<p>CodeIgniter lets you build error reporting into your applications using the functions described below.
-In addition, it has an error logging class that permits error and debugging messages to be saved as text files.</p>
-
-<p class="important"><strong>Note:</strong> By default, CodeIgniter displays all PHP errors.  You might
-wish to change this behavior once your development is complete.  You'll find the <dfn>error_reporting()</dfn>
-function located at the top of your main index.php file. Disabling error reporting will NOT prevent log files
-from being written if there are errors.</p>
-
-<p>Unlike most systems in CodeIgniter, the error functions are simple procedural interfaces that are available
-globally throughout the application.  This approach permits error messages to get triggered without having to worry
-about class/function scoping.</p>
-
-<p>The following functions let you generate errors:</p>
-
-<h2>show_error('<var>message</var>' [, int <var>$status_code</var>= 500 ] )</h2>
-<p>This function will display the error message supplied to it using the following error template:</p>
-<p><dfn>application/errors/</dfn><kbd>error_general.php</kbd></p>
-<p>The optional parameter $status_code determines what HTTP status code should be sent with the error.</p>
-
-<h2>show_404('<var>page</var>' [, '<var>log_error</var>'])</h2>
-<p>This function will display the 404 error message supplied to it using the following error template:</p>
-<p><dfn>application/errors/</dfn><kbd>error_404.php</kbd></p>
-
-<p>The function expects the string passed to it to be the file path to the page that isn't found.
-Note that CodeIgniter automatically shows 404 messages if controllers are not found.</p>
-
-<p>CodeIgniter automatically logs any show_404() calls. Setting the optional second parameter to FALSE will skip logging.</p>
-
-
-<h2>log_message('<var>level</var>', '<samp>message</samp>')</h2>
-
-<p>This function lets you write messages to your log files.  You must supply one of three "levels"
-in the first parameter, indicating what type of message it is (debug, error, info), with the message
-itself in the second parameter.  Example:</p>
-
-<code>
-if ($some_var == "")<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;log_message('error', 'Some variable did not contain a value.');<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;log_message('debug', 'Some variable was correctly set');<br />
-}<br />
-<br />
-log_message('info', 'The purpose of some variable is to provide some value.');<br />
-</code>
-
-<p>There are three message types:</p>
-
-<ol>
-<li>Error Messages.  These are actual errors, such as PHP errors or user errors.</li>
-<li>Debug Messages.  These are messages that assist in debugging. For example, if a class has been initialized, you could log this as debugging info.</li>
-<li>Informational Messages.  These are the lowest priority messages, simply giving information regarding some process.  CodeIgniter doesn't natively generate any info messages but you may want to in your application.</li>
-</ol>
-
-
-<p class="important"><strong>Note:</strong> In order for the log file to actually be written, the
- "logs" folder must be writable.  In addition, you must set the "threshold" for logging in <dfn>application/config/config.php</dfn>.
-You might, for example, only want error messages to be logged, and not the other two types.
-If you set it to zero logging will be disabled.</p>

-<h1>Helper Functions</h1>
-
-<p>Helpers, as the name suggests, help you with tasks.  Each helper file is simply a collection of functions in a particular
-category.  There are <dfn>URL Helpers</dfn>, that assist in creating links, there are <dfn>Form Helpers</dfn>
-that help you create form elements, <dfn>Text Helpers</dfn> perform various text formatting routines,
-<dfn>Cookie Helpers</dfn> set and read cookies, <dfn>File Helpers</dfn> help you deal with files, etc.
-</p>
-
-<p>Unlike most other systems in CodeIgniter, Helpers are not written in an Object Oriented format.  They are simple, procedural functions.
-Each helper function performs one specific task, with no dependence on other functions.</p>
-
-<p>CodeIgniter does not load Helper Files by default, so the first step in using
-a Helper is to load it.  Once loaded, it becomes globally available in your <a href="../general/controllers.html">controller</a> and <a href="../general/views.html">views</a>.</p>
-
-<p>Helpers are typically stored in your <dfn>system/helpers</dfn>, or <dfn>application/helpers </dfn>directory.	CodeIgniter will look first in your <dfn>application/helpers</dfn>
-directory.  If the directory does not exist or the specified helper is not located there CI will instead look in your global
-<dfn>system/helpers</dfn> folder.</p>
-
-
-<h2>Loading a Helper</h2>
-
-<p>Loading a helper file is quite simple using the following function:</p>
-
-<code>$this->load->helper('<var>name</var>');</code>
-
-<p>Where <var>name</var> is the file name of the helper, without the .php file extension or the "helper" part.</p>
-
-<p>For example, to load the <dfn>URL Helper</dfn> file, which is named <var>url_helper.php</var>, you would do this:</p>
-
-<code>$this->load->helper('<var>url</var>');</code>
-
-<p>A helper can be loaded anywhere within your controller functions (or even within your View files, although that's not a good practice),
-as long as you load it before you use it.  You can load your helpers in your controller constructor so that they become available
-automatically in any function, or you can load a helper in a specific function that needs it.</p>
-
-<p class="important">Note: The Helper loading function above does not return a value, so don't try to assign it to a variable.  Just use it as shown.</p>
-
-
-<h2>Loading Multiple Helpers</h2>
-
-<p>If you need to load more than one helper you can specify them in an array, like this:</p>
-
-<code>$this->load->helper( <samp>array(</samp>'<var>helper1</var>', '<var>helper2</var>', '<var>helper3</var>'<samp>)</samp> );</code>
-
-<h2>Auto-loading Helpers</h2>
-
-<p>If you find that you need a particular helper globally throughout your application, you can tell CodeIgniter to auto-load it during system initialization.
-This is done by opening the <var>application/config/autoload.php</var> file and adding the helper to the autoload array.</p>
-
-
-<h2>Using a Helper</h2>
-
-<p>Once you've loaded the Helper File containing the function you intend to use, you'll call it the way you would a standard PHP function.</p>
-
-<p>For example, to create a link using the <dfn>anchor()</dfn> function in one of your view files you would do this:</p>
-
-<code>&lt;?php echo anchor('blog/comments', 'Click Here');?&gt;</code>
-
-<p>Where "Click Here" is the name of the link, and "blog/comments" is the URI to the controller/function you wish to link to.</p>
-
-<h2>"Extending" Helpers</h2>
-
-<p>To "extend" Helpers, create a file in your <dfn>application/helpers/</dfn> folder with an identical name to the existing Helper, but prefixed with <kbd>MY_</kbd> (this item is configurable.  See below.).</p>
-
-<p>If all you need to do is add some functionality to an existing helper - perhaps add a function or two, or change how a particular
-	helper function operates - then it's overkill to replace the entire helper with your version.  In this case it's better to simply
-	"extend" the Helper.  The term "extend" is used loosely since Helper functions are procedural and discrete and cannot be extended
-	in the traditional programmatic sense.  Under the hood, this gives you the ability to add to the functions a Helper provides,
-	or to modify how the native Helper functions operate.</p>
-
-<p>For example, to extend the native <kbd>Array Helper</kbd> you'll create a file named <dfn>application/helpers/</dfn><kbd>MY_array_helper.php</kbd>, and add or override functions:</p>
-
-<code>
-// any_in_array() is not in the Array Helper, so it defines a new function<br />
-function any_in_array($needle, $haystack)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$needle = (is_array($needle)) ? $needle : array($needle);<br />
-	<br />
-&nbsp;&nbsp;&nbsp;&nbsp;foreach ($needle as $item)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (in_array($item, $haystack))<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return TRUE;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-	<br />
-&nbsp;&nbsp;&nbsp;&nbsp;return FALSE;<br />
-}<br />
-<br />
-// random_element() is included in Array Helper, so it overrides the native function<br />
-function random_element($array)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;shuffle($array);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;return array_pop($array);<br />
-}<br />
-</code>
-
-<h3>Setting Your Own Prefix</h3>
-
-<p>The filename prefix for "extending" Helpers is the same used to extend libraries and Core classes.  To set your own prefix, open your <dfn>application/config/config.php</dfn> file and look for this item:</p>
-
-<code>$config['subclass_prefix'] = 'MY_';</code>
-
-<p>Please note that all native CodeIgniter libraries are prefixed with <kbd>CI_</kbd> so DO NOT use that as your prefix.</p>
-
-
-<h2>Now What?</h2>
-
-<p>In the Table of Contents you'll find a list of all the available Helper Files.  Browse each one to see what they do.</p>

-<h1>Hooks - Extending the Framework Core</h1>
-
-<p>CodeIgniter's Hooks feature provides a means to tap into and modify the inner workings of the framework without hacking the core files.
-When CodeIgniter runs it follows a specific execution process, diagramed in the <a href="../overview/appflow.html">Application Flow</a> page.
-There may be instances, however, where you'd like to cause some action to take place at a particular stage in the execution process.
-For example, you might want to run a script right before your controllers get loaded, or right after, or you might want to trigger one of
-your own scripts in some other location.
-</p>
-
-<h2>Enabling Hooks</h2>
-
-<p>The hooks feature can be globally enabled/disabled by setting the following item in the <kbd>application/config/config.php</kbd> file:</p>
-
-<code>$config['enable_hooks'] = TRUE;</code>
-
-
-<h2>Defining a Hook</h2>
-
-<p>Hooks are defined in <dfn>application/config/hooks.php</dfn> file.  Each hook is specified as an array with this prototype:</p>
-
-<code>
-$hook['pre_controller'] = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class'&nbsp;&nbsp;&nbsp;&nbsp;=> 'MyClass',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'function' => 'Myfunction',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename' => 'Myclass.php',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filepath' => 'hooks',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'params'&nbsp;&nbsp;&nbsp;=> array('beer', 'wine', 'snacks')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);</code>
-
-<p><strong>Notes:</strong><br />The array index correlates to the name of the particular hook point you want to
-use.  In the above example the hook point is <kbd>pre_controller</kbd>. A list of hook points is found below.
-The following items should be defined in your associative hook array:</p>
-
-<ul>
-<li><strong>class</strong>&nbsp; The name of the class you wish to invoke. If you prefer to use a procedural function instead of a class, leave this item blank.</li>
-<li><strong>function</strong>&nbsp; The function name you wish to call.</li>
-<li><strong>filename</strong>&nbsp; The file name containing your class/function.</li>
-<li><strong>filepath</strong>&nbsp; The name of the directory containing your script.  Note: Your script must be located in a directory INSIDE your <kbd>application</kbd> folder, so the file path is relative to that folder.  For example, if your script is located in <dfn>application/hooks</dfn>, you will simply use <samp>hooks</samp> as your filepath.  If your script is located in <dfn>application/hooks/utilities</dfn> you will use <samp>hooks/utilities</samp> as your filepath. No trailing slash.</li>
-<li><strong>params</strong>&nbsp; Any parameters you wish to pass to your script. This item is optional.</li>
-</ul>
-
-
-<h2>Multiple Calls to the Same Hook</h2>
-
-<p>If want to use the same hook point with more then one script, simply make your array declaration multi-dimensional, like this:</p>
-
-<code>
-$hook['pre_controller']<kbd>[]</kbd> = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class'&nbsp;&nbsp;&nbsp;&nbsp;=> 'MyClass',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'function' => 'Myfunction',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename' => 'Myclass.php',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filepath' => 'hooks',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'params'&nbsp;&nbsp;&nbsp;=> array('beer', 'wine', 'snacks')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$hook['pre_controller']<kbd>[]</kbd> = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class'&nbsp;&nbsp;&nbsp;&nbsp;=> 'MyOtherClass',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'function' => 'MyOtherfunction',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename' => 'Myotherclass.php',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filepath' => 'hooks',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'params'&nbsp;&nbsp;&nbsp;=> array('red', 'yellow', 'blue')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);</code>
-
-<p>Notice the brackets after each array index:</p>
-
-<code>$hook['pre_controller']<kbd>[]</kbd></code>
-
-<p>This permits you to have the same hook point with multiple scripts.  The order you define your array will be the execution order.</p>
-
-
-<h2>Hook Points</h2>
-
-<p>The following is a list of available hook points.</p>
-
-<ul>
-		<li><strong>pre_system</strong><br />
-			Called very early during system execution.  Only the benchmark and hooks class have been loaded at this point. No routing or other processes have happened.</li>
-		<li><strong>pre_controller</strong><br />
-			Called immediately prior to any of your controllers being called. All base classes, routing, and security checks have been done.</li>
-		<li><strong>post_controller_constructor</strong><br />
-			Called immediately after your controller is instantiated, but prior to any method calls happening.</li>
-		<li><strong>post_controller</strong><br />
-			Called immediately after your controller is fully executed.</li>
-		<li><strong>display_override</strong><br />
-			Overrides the <dfn>_display()</dfn> function, used to send the finalized page to the web browser at the end of system execution.  This permits you to
-			use your own display methodology.  Note that you will need to reference the CI superobject with <dfn>$this->CI =&amp; get_instance()</dfn> and then the finalized data will be available by calling <dfn>$this->CI->output->get_output()</dfn></li>
-		<li><strong>cache_override</strong><br />

-<h1>Using CodeIgniter Libraries</h1>
-
-
-<p>All of the available libraries are located in your <dfn>system/libraries</dfn> folder.
-In most cases, to use one of these classes involves initializing it within a <a href="controllers.html">controller</a> using the following initialization function:</p>
-
-<code>$this->load->library('<var>class name</var>'); </code>
-
-<p>Where <var>class name</var> is the name of the class you want to invoke.  For example, to load the form validation class you would do this:</p>
-
-<code>$this->load->library('<var>form_validation</var>'); </code>
-
-<p>Once initialized you can use it as indicated in the user guide page corresponding to that class.</p>
-
-<p>Additionally, multiple libraries can be loaded at the same time by passing an array of libraries to the load function.</p>
-
-<code>$this->load->library(array('<var>email</var>', '<var>table</var>'));</code>
-
-<h2>Creating Your Own Libraries</h2>

-<h1>Managing your Applications</h1>
-
-<p>By default it is assumed that you only intend to use CodeIgniter to manage one application, which you will build in your
-<dfn>application/</dfn> directory.  It is possible, however, to have multiple sets of applications that share a single
-CodeIgniter installation, or even to rename or relocate your <dfn>application</dfn> folder.</p>
-
-<h2>Renaming the Application Folder</h2>
-
-<p>If you would like to rename your <dfn>application</dfn> folder you may do so as long as you open your main <kbd>index.php</kbd>
-file and set its name using the <samp>$application_folder</samp> variable:</p>
-
-<code>$application_folder = "application";</code>
-
-<h2>Relocating your Application Folder</h2>
-
-<p>It is possible to move your <dfn>application</dfn> folder to a different location on your server than your <kbd>system</kbd> folder.
-To do so open your main <kbd>index.php</kbd> and set a <em>full server path</em> in the <samp>$application_folder</samp> variable.</p>
-
-
-<code>$application_folder = "/Path/to/your/application";</code>
-
-
-<h2>Running Multiple Applications with one CodeIgniter Installation</h2>
-
-<p>If you would like to share a common CodeIgniter installation to manage several different applications simply
-put all of the directories located inside your <kbd>application</kbd> folder into their
-own sub-folder.</p>
-
-<p>For example, let's say you want to create two applications, "foo" and "bar".  You could structure your
-application folders like this:</p>
-
-<code>applications/<var>foo</var>/<br />
-applications/<var>foo</var>/config/<br />
-applications/<var>foo</var>/controllers/<br />
-applications/<var>foo</var>/errors/<br />
-applications/<var>foo</var>/libraries/<br />
-applications/<var>foo</var>/models/<br />
-applications/<var>foo</var>/views/<br />
-applications/<samp>bar</samp>/<br />
-applications/<samp>bar</samp>/config/<br />
-applications/<samp>bar</samp>/controllers/<br />
-applications/<samp>bar</samp>/errors/<br />
-applications/<samp>bar</samp>/libraries/<br />
-applications/<samp>bar</samp>/models/<br />
-applications/<samp>bar</samp>/views/</code>
-
-
-<p>To select a particular application for use requires that you open your main <kbd>index.php</kbd> file and set the <dfn>$application_folder</dfn>
-variable.  For example, to select the "foo" application for use you would do this:</p>
-
-<code>$application_folder = "applications/foo";</code>
-
-<p class="important"><strong>Note:</strong>&nbsp; Each of your applications will need its own <dfn>index.php</dfn> file which
-calls the desired application.  The index.php file can be named anything you want.</p>

-<h1>Models</h1>
-

-
-<h2><a name="what"></a>What is a Model?</h2>
-
-<p>Models are PHP classes that are designed to work with information in your database.  For example, let's say
-you use CodeIgniter to manage a blog.  You might have a model class that contains functions to insert, update, and
-retrieve your blog data. Here is an example of what such a model class might look like:</p>
-
-<code>
-class&nbsp;Blogmodel&nbsp;extends&nbsp;CI_Model&nbsp;{<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;var $title&nbsp;&nbsp; = '';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;var $content = '';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;var $date&nbsp;&nbsp;&nbsp; = '';<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;__construct()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Call the Model constructor<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;get_last_ten_entries()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$query = $this->db->get('entries', 10);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return $query->result();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;insert_entry()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->title&nbsp;&nbsp; = $_POST['title']; // please read the below note<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->content = $_POST['content'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->date&nbsp;&nbsp;&nbsp; = time();<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->db->insert('entries',&nbsp;$this);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;update_entry()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->title&nbsp;&nbsp; = $_POST['title'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->content = $_POST['content'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->date&nbsp;&nbsp;&nbsp; = time();<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->db->update('entries',&nbsp;$this, array('id' => $_POST['id']));<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-<br />
-}</code>
-
-<p>Note: The functions in the above example use the <a href="../database/active_record.html">Active Record</a> database functions.</p>
-<p class="important"><strong>Note:</strong> For the sake of simplicity in this example we're using $_POST directly.  This is generally bad practice, and a more common approach would be to use the <a href="../libraries/input.html">Input Class</a> $this-&gt;input-&gt;post('title')</p>
-<h2><a name="anatomy"></a>Anatomy of a Model</h2>
-
-<p>Model classes are stored in your <dfn>application/models/</dfn> folder.  They can be nested within sub-folders if you
-want this type of organization.</p>
-
-<p>The basic prototype for a model class is this:</p>
-
-
-<code>
-class&nbsp;<var>Model_name</var>&nbsp;extends&nbsp;CI_Model&nbsp;{<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;<var>__construct</var>()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<p>Where <var>Model_name</var> is the name of your class.  Class names <strong>must</strong> have the first letter capitalized with the rest of the name lowercase.
-Make sure your class extends the base Model class.</p>
-
-<p>The file name will be a lower case version of your class name.  For example, if your class is this:</p>
-
-<code>
-class&nbsp;<var>User_model</var>&nbsp;extends&nbsp;CI_Model&nbsp;{<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;<var>__construct</var>()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<p>Your file will be this:</p>
-
-<code>application/models/<var>user_model.php</var></code>
-
-
-
-<h2><a name="loading"></a>Loading a Model</h2>
-
-<p>Your models will typically be loaded and called from within your <a href="controllers.html">controller</a> functions.
-To load a model you will use the following function:</p>
-
-<code>$this->load->model('<var>Model_name</var>');</code>
-
-<p>If your model is located in a sub-folder, include the relative path from your models folder.  For example, if
-you have a model located at <dfn>application/models/blog/queries.php</dfn> you'll load it using:</p>
-
-<code>$this->load->model('<var>blog/queries</var>');</code>
-
-
-<p>Once loaded, you will access your model functions using an object with the same name as your class:</p>
-
-<code>
-$this->load->model('<var>Model_name</var>');<br />
-<br />
-$this-><var>Model_name</var>->function();
-</code>
-
-<p>If you would like your model assigned to a different object name you can specify it via the second parameter of the loading
-function:</p>
-
-
-<code>
-$this->load->model('<var>Model_name</var>', '<kbd>fubar</kbd>');<br />
-<br />
-$this-><kbd>fubar</kbd>->function();
-</code>
-
-<p>Here is an example of a controller, that loads a model, then serves a view:</p>
-
-<code>
-class&nbsp;Blog_controller&nbsp;extends&nbsp;CI_Controller&nbsp;{<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;blog()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->model('Blog');<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$data['query'] = $this->Blog->get_last_ten_entries();<br /><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('blog', $data);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<h2><a name="auto_load_model" id="auto_load_model"></a>Auto-loading Models</h2>
-<p>If you find that you need a particular model globally throughout your  application, you can tell CodeIgniter to auto-load it during system  initialization.  This is done by opening the application/config/autoload.php file and adding the model to the autoload array.</p>
-
-
-<h2><a name="conn"></a>Connecting to your Database</h2>
-
-<p>When a model is loaded it does <strong>NOT</strong> connect automatically to your database.  The following options for connecting are available to you:</p>
-
-<ul>
-<li>You can connect using the standard database methods <a href="../database/connecting.html">described here</a>, either from within your Controller class or your Model class.</li>
-<li>You can tell the model loading function to auto-connect by passing <kbd>TRUE</kbd> (boolean) via the third parameter,
-and connectivity settings, as defined in your database config file will be used:
-
-	<code>$this->load->model('<var>Model_name</var>', '', <kbd>TRUE</kbd>);</code>
-	</li>
-
-
-<li>You can manually pass database connectivity settings via the third parameter:
-
-
-		<code>$config['hostname'] = "localhost";<br />
-		$config['username'] = "myusername";<br />
-		$config['password'] = "mypassword";<br />
-		$config['database'] = "mydatabase";<br />
-		$config['dbdriver'] = "mysql";<br />
-		$config['dbprefix'] = "";<br />
-		$config['pconnect'] = FALSE;<br />
-		$config['db_debug'] = TRUE;<br />
-		<br />
-		$this->load->model('<var>Model_name</var>', '', <kbd>$config</kbd>);</code></li>
-</ul>

-<h1>Profiling Your Application</h1>
-
-<p>The Profiler Class will display benchmark results, queries you have run, and $_POST data at the bottom of your pages.
-This information can be useful during development in order to help with debugging and optimization.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p class="important"><strong>Important:</strong>&nbsp; This class does <kbd>NOT</kbd> need to be initialized. It is loaded automatically by the
-<a href="../libraries/output.html">Output Class</a> if profiling is enabled as shown below.</p>
-
-<h2>Enabling the Profiler</h2>
-
-	<p>To enable the profiler place the following function anywhere within your <a href="controllers.html">Controller</a> functions:</p>
-	<code>$this->output->enable_profiler(TRUE);</code>
-
-	<p>When enabled a report will be generated and inserted at the bottom of your pages.</p>
-
-	<p>To disable the profiler you will use:</p>
-	<code>$this->output->enable_profiler(FALSE);</code>
-
-
-<h2>Setting Benchmark Points</h2>
-
-	<p>In order for the Profiler to compile and display your benchmark data you must name your mark points using specific syntax.</p>
-
-	<p>Please read the information on setting Benchmark points in <a href="../libraries/benchmark.html">Benchmark Class</a> page.</p>
-
-
-<h2>Enabling and Disabling Profiler Sections</h2>
-
-	<p>Each section of Profiler data can be enabled or disabled by setting a corresponding config variable to <var>TRUE</var> or <var>FALSE</var>.  This can be done one of two ways.  First, you can set application wide defaults with the <dfn>application/config/profiler.php</dfn> config file.</p>
-
-	<code>$config['config']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br />
-	$config['queries']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br /></code>
-
-	<p>In your controllers, you can override the defaults and config file values by calling the <kbd>set_profiler_sections()</kbd> method of the <a href="../libraries/output.html">Output class</a>:</p>
-
-	<code>$sections = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;'config' &nbsp;=> TRUE,<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;'queries' => TRUE<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-	<br />
-	$this->output->set_profiler_sections($sections);</code>
-
-	<p>Available sections and the array key used to access them are described in the table below.</p>
-
-	<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">

-<h1>Reserved Names</h1>
-
-<p>In order to help out, CodeIgniter uses a series of functions and names in its operation. Because of this, some names cannot be used by a developer. Following is a list of reserved names that cannot be used.</p>
-<h3>Controller names</h3>
-<p>Since your controller classes will extend the main application controller you
-must be careful not to name your functions identically to the ones used by that class, otherwise your local functions
-will override them.  The following
-is a list of reserved names.  Do not name your controller any of these:</p>
-<ul>
-	<li>Controller</li>
-	<li>CI_Base</li>
-	<li>_ci_initialize</li>
-	<li>Default</li>
-	<li>index</li>
-</ul>
-<h3>Functions</h3>
-<ul>
-	<li>is_really_writable()</li>
-	<li>load_class()</li>
-	<li>get_config()</li>
-	<li>config_item()</li>
-	<li>show_error()</li>
-	<li>show_404()</li>
-	<li>log_message()</li>
-	<li>_exception_handler()</li>
-	<li>get_instance()</li>
-	</ul>
-<h3>Variables</h3>
-<ul>
-	<li>$config</li>
-	<li>$mimes</li>
-	<li>$lang</li>
-</ul>
-<h3>Constants</h3>
-<ul>
-	<li>ENVIRONMENT</li>
-	<li>EXT</li>
-	<li>FCPATH</li>
-	<li>SELF</li>
-	<li>BASEPATH</li>
-	<li>APPPATH</li>

-	<li>DIR_WRITE_MODE</li>
-	<li>FOPEN_READ</li>

-<h1>URI Routing</h1>
-
-<p>Typically there is a one-to-one relationship between a URL string and its corresponding controller class/method.
-The segments in a URI normally follow this pattern:</p>
-
-<code>example.com/<dfn>class</dfn>/<samp>function</samp>/<var>id</var>/</code>
-
-<p>In some instances, however, you may want to remap this relationship so that a different class/function can be called
-instead of the one corresponding to the URL.</p>
-
-<p>For example, lets say you want your URLs to have this prototype:</p>
-
-<p>
-example.com/product/1/<br />
-example.com/product/2/<br />
-example.com/product/3/<br />
-example.com/product/4/
-</p>
-
-<p>Normally the second segment of the URL is reserved for the function name, but in the example above it instead has a product ID.
-To overcome this, CodeIgniter allows you to remap the URI handler.</p>
-
-
-<h2>Setting your own routing rules</h2>
-
-<p>Routing rules are defined in your <var>application/config/routes.php</var> file.  In it you'll see an array called <dfn>$route</dfn> that
-permits you to specify your own routing criteria. Routes can either be specified using <dfn>wildcards</dfn> or <dfn>Regular Expressions</dfn></p>
-
-
-<h2>Wildcards</h2>
-
-<p>A typical wildcard route might look something like this:</p>
-
-<code>$route['product/:num'] = "catalog/product_lookup";</code>
-
-<p>In a route, the array key contains the URI to be matched, while the array value  contains the destination it should be re-routed to.
-In the above example, if the literal word "product" is found in the first segment of the URL, and a number is found in the second segment,
-the "catalog" class and the "product_lookup" method are instead used.</p>
-
-<p>You can match literal values or you can use two wildcard types:</p>
-
-<p><strong>(:num)</strong> will match a segment containing only numbers.<br />
-<strong>(:any)</strong> will match a segment containing any character.
-</p>
-
-<p class="important"><strong>Note:</strong> Routes will run in the order they are defined.
-Higher routes will always take precedence over lower ones.</p>
-
-<h2>Examples</h2>
-
-<p>Here are a few routing examples:</p>
-
-<code>$route['journals'] = "blogs";</code>
-<p>A URL containing the word "journals" in the first segment will be remapped to the "blogs" class.</p>
-
-<code>$route['blog/joe'] = "blogs/users/34";</code>
-<p>A URL containing the segments blog/joe will be remapped to the "blogs" class and the "users" method.  The ID will be set to "34".</p>
-
-<code>$route['product/(:any)'] = "catalog/product_lookup";</code>
-<p>A URL with "product" as the first segment, and anything in the second will be remapped to the "catalog" class and the  "product_lookup" method.</p>
-
-<code>$route['product/(:num)'] = "catalog/product_lookup_by_id/$1";</code>
-<p>A URL with "product" as the first segment, and a number in the second will be remapped to the "catalog" class and the "product_lookup_by_id" method passing in the match as a variable to the function.</p>
-
-<p class="important"><strong>Important:</strong> Do not use leading/trailing slashes.</p>
-
-<h2>Regular Expressions</h2>
-
-<p>If you prefer you can use regular expressions to define your routing rules.  Any valid regular expression is allowed, as are back-references.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; If you use back-references you must use the dollar syntax rather than the double backslash syntax.</p>
-
-<p>A typical RegEx route might look something like this:</p>
-
-<code>$route['products/([a-z]+)/(\d+)'] = "$1/id_$2";</code>
-
-<p>In the above example, a URI similar to <dfn>products/shirts/123</dfn> would instead call the <dfn>shirts</dfn> controller class and the <dfn>id_123</dfn> function.</p>
-
-<p>You can also mix and match wildcards with regular expressions.</p>
-
-<h2>Reserved Routes</h2>
-
-<p>There are two reserved routes:</p>
-
-<code>$route['default_controller'] = 'welcome';</code>
-
-<p>This route indicates which controller class should be loaded if the URI contains no data, which will be the case
-when people load your root URL. In the above example, the "welcome" class would be loaded.  You
-are encouraged to always have a default route otherwise a 404 page will appear by default.</p>
-
-<code>$route['404_override'] = '';</code>
-
-<p>This route indicates which controller class should be loaded if the requested controller is not found. It will override the default 404
-error page. It won't affect to the <samp>show_404()</samp> function, which will continue loading the default <dfn>error_404.php</dfn> file at <var>application/errors/error_404.php</var>.</p>
-
-<p class="important"><strong>Important:</strong>&nbsp; The reserved routes must come before any wildcard or regular expression routes.</p>

-<h1>Security</h1>
-
-<p>This page describes some "best practices" regarding web security, and details
-CodeIgniter's internal security features.</p>
-
-
-<h2>URI Security</h2>
-
-<p>CodeIgniter is fairly restrictive regarding which characters it allows in your URI strings in order to help
-minimize the possibility that malicious data can be passed to your application.  URIs may only contain the following:
-</p>
-
-<ul>
-<li>Alpha-numeric text</li>
-<li>Tilde: ~ </li>
-<li>Period: .</li>
-<li>Colon: :</li>
-<li>Underscore: _</li>
-<li>Dash: -</li>
-</ul>
-
-<h2>Register_globals</h2>
-
-<p>During system initialization all global variables are unset, except those found in the $_GET, $_POST, and $_COOKIE arrays. The unsetting
-routine is effectively the same as register_globals = off.</p>
-
-<a name="error_reporting"></a>
-<h2>error_reporting</h2>
-
-<p>
-    In production environments, it is typically desirable to disable PHP's 
-    error reporting by setting the internal error_reporting flag to a value of 0. This disables native PHP
-    errors from being rendered as output, which may potentially contain
-    sensitive information.
-</p>
-
-<p>
-    Setting CodeIgniter's <kbd>ENVIRONMENT</kbd> constant in index.php to a
-    value of '<kbd>production</kbd>' will turn off these errors. In development
-    mode, it is recommended that a value of '<kbd>development</kbd>' is used.
-    More information about differentiating between environments can be found
-    on the <a href="environments.html">Handling Environments</a> page.
-</p>
-
-<h2>magic_quotes_runtime</h2>
-
-<p>The magic_quotes_runtime directive is turned off during system initialization so that you don't have to remove slashes when
-retrieving data from your database.</p>
-
-<h1>Best Practices</h1>
-
-<p>Before accepting any data into your application, whether it be POST data from a form submission, COOKIE data, URI data,
-XML-RPC data, or even data from the SERVER array, you are encouraged to practice this three step approach:</p>
-
-<ol>
-<li>Filter the data as if it were tainted.</li>
-<li>Validate the data to ensure it conforms to the correct  type, length, size, etc. (sometimes this step can replace step one)</li>
-<li>Escape the data before submitting it into your database.</li>
-</ol>
-
-<p>CodeIgniter provides the following functions to assist in this process:</p>
-
-<ul>
-
-<li><h2>XSS Filtering</h2>
-
-<p>CodeIgniter comes with a Cross Site Scripting filter.  This filter looks for commonly
-used techniques to embed malicious Javascript into your data, or other types of code that attempt to hijack cookies
-or do other malicious things. The XSS Filter is described <a href="../libraries/security.html">here</a>.
-</p>
-</li>
-
-<li><h2>Validate the data</h2>
-
-<p>CodeIgniter has a <a href="../libraries/form_validation.html">Form Validation Class</a> that assists you in validating, filtering, and prepping
-your data.</p>
-</li>
-
-<li><h2>Escape all data before database insertion</h2>
-
-<p>Never insert information into your database without escaping it. Please see the section that discusses
-<a href="../database/queries.html">queries</a> for more information.</p>
-
-</li>
-
-</ul>

-		<div class="guidelineDetails">
-			<p>Files should be saved with Unicode (UTF-8) encoding.  The <abbr title="Byte Order Mark">BOM</abbr>
-				should <em>not</em> be used.  Unlike UTF-16 and UTF-32, there's no byte order to indicate in

-		</div>
-
-		<h2><a name="php_closing_tag"></a>PHP Closing Tag</h2>
-		<div class="guidelineDetails">
-			<p>The PHP closing tag on a PHP document <strong>?&gt;</strong> is optional to the PHP parser.  However, if used, any whitespace following the closing tag, whether introduced
-				by the developer, user, or an FTP application, can cause unwanted output, PHP errors, or if the latter are suppressed, blank pages.  For this reason, all PHP files should
-				<strong>OMIT</strong> the closing PHP tag, and instead use a comment block to mark the end of file and it's location relative to the application root.
-				This allows you to still identify a file as being complete and not truncated.</p>
-<code><strong>INCORRECT</strong>:
-&lt;?php
-
-echo "Here's my code!";
-
-?&gt;
-
-<strong>CORRECT</strong>:
-&lt;?php
-
-echo "Here's my code!";
-
-/* End of file myfile.php */
-/* Location: ./system/modules/mymodule/myfile.php */
-</code>
-		</div>
-
-
-		<h2><a name="class_and_method_naming"></a>Class and Method Naming</h2>
-		<div class="guidelineDetails">
-			<p>Class names should always start with an uppercase letter.  Multiple words should be separated with an underscore, and not CamelCased.  All other class methods should be entirely lowercased and named to clearly indicate their function, preferably including a verb.  Try to avoid overly long and verbose names.</p>
-
-	<code><strong>INCORRECT</strong>:
-class superclass
-class SuperClass
-
-<strong>CORRECT</strong>:
-class Super_class</code>
-
-
-	<code>class Super_class {
-
-	function __construct()
-	{
-
-	}
-}</code>
-
-			<p>Examples of improper and proper method naming:</p>
-
-	<code><strong>INCORRECT</strong>:
-function fileproperties()		// not descriptive and needs underscore separator
-function fileProperties()		// not descriptive and uses CamelCase
-function getfileproperties()		// Better!  But still missing underscore separator
-function getFileProperties()		// uses CamelCase
-function get_the_file_properties_from_the_file()	// wordy
-
-<strong>CORRECT</strong>:
-function get_file_properties()	// descriptive, underscore separator, and all lowercase letters</code>
-
-		</div>
-
-
-		<h2><a name="variable_names"></a>Variable Names</h2>
-		<div class="guidelineDetails">
-			<p>The guidelines for variable naming is very similar to that used for class methods.  Namely, variables should contain only lowercase letters, use underscore separators, and be reasonably named to indicate their purpose and contents. Very short, non-word variables should only be used as iterators in for() loops.</p>
-<code><strong>INCORRECT</strong>:
-$j = &apos;foo&apos;;		// single letter variables should only be used in for() loops
-$Str			// contains uppercase letters
-$bufferedText		// uses CamelCasing, and could be shortened without losing semantic meaning
-$groupid		// multiple words, needs underscore separator
-$name_of_last_city_used	// too long
-
-<strong>CORRECT</strong>:
-for ($j = 0; $j &lt; 10; $j++)
-$str
-$buffer
-$group_id
-$last_city
-</code>
-		</div>
-
-
-		<h2><a name="commenting"></a>Commenting</h2>
-		<div class="guidelineDetails">
-			<p>In general, code should be commented prolifically.  It not only helps describe the flow and intent of the code for less experienced programmers, but can prove invaluable when returning to your own code months down the line.  There is not a required format for comments, but the following are recommended.</p>
-
-			<p><a href="http://manual.phpdoc.org/HTMLSmartyConverter/HandS/phpDocumentor/tutorial_phpDocumentor.howto.pkg.html#basics.docblock">DocBlock</a> style comments preceding class and method declarations so they can be picked up by IDEs:</p>
-
-<code>/**
- * Super Class
- *
- * @package	Package Name
- * @subpackage	Subpackage
- * @category	Category
- * @author	Author Name
- * @link	http://example.com
- */
-class Super_class {</code>
-
-<code>/**
- * Encodes string for use in XML
- *
- * @access	public
- * @param	string
- * @return	string
- */
-function xml_encode($str)</code>
-
-			<p>Use single line comments within code, leaving a blank line between large comment blocks and code.</p>
-
-<code>// break up the string by newlines
-$parts = explode("\n", $str);
-
-// A longer comment that needs to give greater detail on what is
-// occurring and why can use multiple single-line comments.  Try to
-// keep the width reasonable, around 70 characters is the easiest to
-// read.  Don't hesitate to link to permanent external resources
-// that may provide greater detail:
-//
-// http://example.com/information_about_something/in_particular/
-
-$parts = $this->foo($parts);
-</code>
-		</div>
-
-
-		<h2><a name="constants"></a>Constants</h2>
-		<div class="guidelineDetails">
-			<p>Constants follow the same guidelines as do variables, except constants should always be fully uppercase.  <em>Always use CodeIgniter constants when appropriate, i.e. SLASH, LD, RD, PATH_CACHE, etc.</em></p>

-			<p>Some PHP functions return FALSE on failure, but may also have a valid return value of "" or 0, which would evaluate to FALSE in loose comparisons.  Be explicit by comparing the variable type when using these return values in conditionals to ensure the return value is indeed what you expect, and not a value that has an equivalent loose-type evaluation.</p>
-			<p>Use the same stringency in returning and checking your own variables.  Use <strong>===</strong> and <strong>!==</strong> as necessary.
-
-<code><strong>INCORRECT</strong>:
-// If 'foo' is at the beginning of the string, strpos will return a 0,
-// resulting in this conditional evaluating as TRUE

-		<p>See also information regarding <a href="http://us3.php.net/manual/en/language.types.type-juggling.php#language.types.typecasting">typecasting</a>, which can be quite useful.  Typecasting has a slightly different effect which may be desirable.  When casting a variable as a string, for instance, NULL and boolean FALSE variables become empty strings, 0 (and other numbers) become strings of digits, and boolean TRUE becomes "1":</p>

-
-		<h2><a name="whitespace_in_files"></a>Whitespace in Files</h2>
-		<div class="guidelineDetails">
-			<p>No whitespace can precede the opening PHP tag or follow the closing PHP tag.  Output is buffered, so whitespace in your files can cause output to begin before CodeIgniter outputs its content, leading to errors and an inability for CodeIgniter to send proper headers.  In the examples below, select the text with your mouse to reveal the incorrect whitespace.</p>
-
-			<p><strong>INCORRECT</strong>:</p>
-<code>
-&lt;?php
-	// ...there is whitespace and a linebreak above the opening PHP tag
-	// as well as whitespace after the closing PHP tag
-?&gt;

-
-		</div>
-
-
-		<h2><a name="compatibility"></a>Compatibility</h2>
-		<div class="guidelineDetails">
-			<p>Unless specifically mentioned in your add-on's documentation, all code must be compatible with PHP version 5.1+.  Additionally, do not use PHP functions that require non-default libraries to be installed unless your code contains an alternative method when the function is not available, or you implicitly document that your add-on requires said PHP libraries.</p>
-		</div>
-
-
-
-		<h2><a name="class_and_file_names_using_common_words"></a>Class and File Names using Common Words</h2>
-		<div class="guidelineDetails">
-			<p>When your class or filename is a common word, or might quite likely be identically named in another PHP script, provide a unique prefix to help prevent collision.  Always realize that your end users may be running other add-ons or third party PHP scripts.  Choose a prefix that is unique to your identity as a developer or company.</p>
-
-<code><strong>INCORRECT</strong>:
-class Email		pi.email.php
-class Xml		ext.xml.php
-class Import		mod.import.php
-
-<strong>CORRECT</strong>:
-class Pre_email		pi.pre_email.php
-class Pre_xml		ext.pre_xml.php
-class Pre_import	mod.pre_import.php
-</code>
-		</div>
-
-
-		<h2><a name="database_table_names"></a>Database Table Names</h2>
-		<div class="guidelineDetails">
-			<p>Any tables that your add-on might use must use the 'exp_' prefix, followed by a prefix uniquely identifying you as the developer or company, and then a short descriptive table name.  You do not need to be concerned about the database prefix being used on the user's installation, as CodeIgniter's database class will automatically convert 'exp_' to what is actually being used.</p>
-
-<code><strong>INCORRECT</strong>:
-email_addresses		// missing both prefixes
-pre_email_addresses	// missing exp_ prefix
-exp_email_addresses	// missing unique prefix
-
-<strong>CORRECT</strong>:
-exp_pre_email_addresses
-</code>
-
-			<p class="important"><strong>NOTE:</strong> Be mindful that MySQL has a limit of 64 characters for table names.  This should not be an issue as table names that would exceed this would likely have unreasonable names.  For instance, the following table name exceeds this limitation by one character.  Silly, no? <strong>exp_pre_email_addresses_of_registered_users_in_seattle_washington</strong>
-		</div>
-
-
-
-		<h2><a name="one_file_per_class"></a>One File per Class</h2>
-		<div class="guidelineDetails">
-			<p>Use separate files for each class your add-on uses, unless the classes are <em>closely related</em>.  An example of CodeIgniter files that contains multiple classes is the Database class file, which contains both the DB class and the DB_Cache class, and the Magpie plugin, which contains both the Magpie and Snoopy classes.</p>
-		</div>
-
-
-
-		<h2><a name="whitespace"></a>Whitespace</h2>
-		<div class="guidelineDetails">
-			<p>Use tabs for whitespace in your code, not spaces.  This may seem like a small thing, but using tabs instead of whitespace allows the developer looking at your code to have indentation at levels that they prefer and customize in whatever application they use.  And as a side benefit, it results in (slightly) more compact files, storing one tab character versus, say, four space characters.</p>
-		</div>
-
-
-
-		<h2><a name="line_breaks"></a>Line Breaks</h2>
-		<div class="guidelineDetails">
-			<p>Files must be saved with Unix line breaks.  This is more of an issue for developers who work in Windows, but in any case ensure that your text editor is setup to save files with Unix line breaks.</p>
-		</div>
-
-
-
-		<h2><a name="code_indenting"></a>Code Indenting</h2>
-		<div class="guidelineDetails">
-			<p>Use Allman style indenting.  With the exception of Class declarations, braces are always placed on a line by themselves, and indented at the same level as the control statement that "owns" them.</p>

-		<div class="guidelineDetails">
-			<p>In general, parenthesis and brackets should not use any additional spaces.  The exception is that a space should always follow PHP control structures that accept arguments with parenthesis (declare, do-while, elseif, for, foreach, if, switch, while), to help distinguish them from functions and increase readability.</p>

-
-			<p>Make sure that while developing your add-on, error reporting is enabled for ALL users, and that display_errors is enabled in the PHP environment.  You can check this setting with:</p>
-
-<code>if (ini_get('display_errors') == 1)

-
-			<p>On some servers where display_errors is disabled, and you do not have the ability to change this in the php.ini, you can often enable it with:</p>

-<code>ini_set('display_errors', 1);</code>
-
-			<p class="important"><strong>NOTE:</strong> Setting the <a href="http://us.php.net/manual/en/ref.errorfunc.php#ini.display-errors">display_errors</a> setting with ini_set() at runtime is not identical to having it enabled in the PHP environment.

-<h1>CodeIgniter URLs</h1>
-
-<p>By default, URLs in CodeIgniter are designed to be search-engine and human friendly.  Rather than using the standard "query string"
-approach to URLs that is synonymous with dynamic systems, CodeIgniter uses a <strong>segment-based</strong> approach:</p>
-
-<code>example.com/<var>news</var>/<dfn>article</dfn>/<samp>my_article</samp></code>
-
-<p class="important"><strong>Note:</strong> Query string URLs can be optionally enabled, as described below.</p>
-
-<h2>URI Segments</h2>
-
-<p>The segments in the URL, in following with the Model-View-Controller approach, usually represent:</p>
-
-<code>example.com/<var>class</var>/<dfn>function</dfn>/<samp>ID</samp></code>
-
-<ol>
-<li>The first segment represents the controller <strong>class</strong> that should be invoked.</li>
-<li>The second segment represents the class <strong>function</strong>, or method, that should be called.</li>
-<li>The third, and any additional segments, represent the ID and any variables that will be passed to the controller.</li>
-</ol>
-
-<p>The <a href="../libraries/uri.html">URI Class</a> and the <a href="../helpers/url_helper.html">URL Helper</a>
-contain functions that make it easy to work with your URI data.  In addition, your URLs can be remapped using the
-<a href="routing.html">URI Routing</a> feature for more flexibility.</p>
-
-
-
-<h2>Removing the index.php file</h2>
-
-<p>By default, the <strong>index.php</strong> file will be included in your URLs:</p>
-
-<code>example.com/<var>index.php</var>/news/article/my_article</code>
-
-<p>You can easily remove this file by using a .htaccess file with some simple rules. Here is an example
- of such a file, using the "negative" method in which everything is redirected except the specified items:</p>
-
-<code>RewriteEngine on<br />
-RewriteCond $1 !^(index\.php|images|robots\.txt)<br />
-RewriteRule ^(.*)$ /index.php/$1 [L]</code>
-
-<p>In the above example, any HTTP request other than those for index.php, images, and robots.txt is treated as
-a request for your index.php file.</p>
-
-
-<h2>Adding a URL Suffix</h2>
-
-<p>In your <dfn>config/config.php</dfn> file you can specify a suffix that will be added to all URLs generated
-by CodeIgniter.  For example, if a URL is this:</p>
-
-<code>example.com/index.php/products/view/shoes</code>
-
-<p>You can optionally add a suffix, like <kbd>.html</kbd>, making the page appear to be of a certain type:</p>
-
-<code>example.com/index.php/products/view/shoes.html</code>
-
-
-<h2>Enabling Query Strings</h2>
-
-<p>In some cases you might prefer to use query strings URLs:</p>
-
-<code>index.php?c=products&amp;m=view&amp;id=345</code>
-
-<p>CodeIgniter optionally supports this capability, which can be enabled in your <dfn>application/config.php</dfn> file. If you
-open your config file you'll see these items:</p>
-
-<code>$config['enable_query_strings'] = FALSE;<br />
-$config['controller_trigger'] = 'c';<br />
-$config['function_trigger'] = 'm';</code>
-
-<p>If you change "enable_query_strings" to TRUE this feature will become active.  Your controllers and functions will then
-be accessible using the "trigger" words you've set to invoke your controllers and methods:</p>
-
-<code>index.php?c=controller&amp;m=method</code>
-
-<p class="important"><strong>Please note:</strong> If you are using query strings you will have to build your own URLs, rather than utilizing
-the URL helpers (and other helpers that generate URLs, like some of the form helpers) as these are designed to work with
-segment based URLs.</p>

-<h1>Views</h1>
-
-<p>A <dfn>view</dfn> is simply a web page, or a page fragment, like a header, footer, sidebar, etc.
-In fact, views can flexibly be embedded within other views (within other views, etc., etc.) if you need this type
-of hierarchy.</p>
-
-<p>Views are never called directly, they must be loaded by a <a href="controllers.html">controller</a>.  Remember that in an MVC framework, the Controller acts as the
-traffic cop, so it is responsible for fetching a particular view. If you have not read the <a href="controllers.html">Controllers</a> page
-you should do so before continuing.</p>
-
-<p>Using the example controller you created in the <a href="controllers.html">controller</a> page, let's add a view to it.</p>
-
-<h2>Creating a View</h2>
-
-<p>Using your text editor, create a file called <dfn>blogview.php</dfn>, and put this in it:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;html>
-&lt;head>
-&lt;title>My Blog&lt;/title>
-&lt;/head>
-&lt;body>
-	&lt;h1>Welcome to my Blog!&lt;/h1>
-&lt;/body>
-&lt;/html>
-</textarea>
-
-<p>Then save the file in your <dfn>application/views/</dfn> folder.</p>
-
-<h2>Loading a View</h2>
-
-<p>To load a particular view file you will use the following function:</p>
-
-<code>$this->load->view('<var>name</var>');</code>
-
-<p>Where <var>name</var> is the name of your view file.  Note: The .php file extension does not need to be specified unless you use something other than <kbd>.php</kbd>.</p>
-
-
-<p>Now, open the controller file you made earlier called <dfn>blog.php</dfn>, and replace the echo statement with the view loading function:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;?php
-class Blog extends CI_Controller {
-
-	function index()
-	{
-		$this->load->view('blogview');
-	}
-}
-?&gt;
-</textarea>
-
-
-<p>If you visit your site using the URL you did earlier you should see your new view.  The URL was similar to this:</p>
-
-<code>example.com/index.php/<var>blog</var>/</code>
-
-<h2>Loading multiple views</h2>
-<p>CodeIgniter will intelligently handle  multiple calls to $this-&gt;load-&gt;view from within a controller.  If more than one call happens they will be appended together. For example, you may wish to have a header view, a menu view, a content view, and a footer view. That might look something like this:</p>
-<p><code>&lt;?php<br />
-<br />
-class Page extends CI_Controller {<br /><br />
-
- &nbsp;&nbsp;&nbsp;function index()<br />
-&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$data['page_title'] =  'Your title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('header');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('menu');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('content', $data);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('footer');<br />
-&nbsp;&nbsp;&nbsp;}<br />
-<br />
-}<br />
-	?&gt;</code></p>
-<p>In the example above, we are using &quot;dynamically added data&quot;, which you will see below.</p>
-<h2>Storing Views within Sub-folders</h2>
-<p>Your view files can also be stored within sub-folders if you prefer that type of organization.  When doing so you will need
-to include the folder name loading the view.  Example:</p>
-
-<code>$this->load->view('<kbd>folder_name</kbd>/<var>file_name</var>');</code>
-
-
-<h2>Adding Dynamic Data to the View</h2>
-
-<p>Data is passed from the controller to the view by way of an <strong>array</strong> or an <strong>object</strong> in the second
-parameter of the view loading function. Here is an example using an array:</p>
-
-<code>$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'My Title',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading' => 'My Heading',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'message' => 'My Message'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->load->view('blogview', <var>$data</var>);</code>
-
-<p>And here's an example using an object:</p>
-
-<code>$data = new Someclass();<br />
-$this->load->view('blogview', <var>$data</var>);</code>
-
-<p>Note: If you use an object, the class variables will be turned into array elements.</p>
-
-
-<p>Let's try it with your controller file.  Open it add this code:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="14">
-&lt;?php
-class Blog extends CI_Controller {
-
-	function index()
-	{
-		$data['title'] = "My Real Title";
-		$data['heading'] = "My Real Heading";
-
-		$this->load->view('blogview', $data);
-	}
-}
-?&gt;
-</textarea>
-
-
-<p>Now open your view file and change the text to variables that correspond to the array keys in your data:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;html>
-&lt;head>
-&lt;title>&lt;?php echo $title;?>&lt;/title>
-&lt;/head>
-&lt;body>
-	&lt;h1>&lt;?php echo $heading;?>&lt;/h1>
-&lt;/body>
-&lt;/html>
-</textarea>
-
-<p>Then load the page at the URL you've been using and you should see the variables replaced.</p>
-
-<h2>Creating Loops</h2>
-
-<p>The data array you pass to your view files is not limited to simple variables.  You can
-pass multi dimensional arrays, which can be looped to generate multiple rows.  For example, if you
-pull data from your database it will typically be in the form of a multi-dimensional array.</p>
-
-<p>Here's a simple example. Add this to your controller:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="17">
-&lt;?php
-class Blog extends CI_Controller {
-
-	function index()
-	{
-		$data['todo_list'] = array('Clean House', 'Call Mom', 'Run Errands');
-
-		$data['title'] = "My Real Title";
-		$data['heading'] = "My Real Heading";
-
-		$this->load->view('blogview', $data);
-	}
-}
-?&gt;
-</textarea>
-
-
-<p>Now open your view file and create a loop:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="24">
-&lt;html>
-&lt;head>
-&lt;title>&lt;?php echo $title;?>&lt;/title>
-&lt;/head>
-&lt;body>
-&lt;h1>&lt;?php echo $heading;?>&lt;/h1>
-
-&lt;h3>My Todo List&lt;/h3>
-
-&lt;ul>
-&lt;?php foreach ($todo_list as $item):?>
-
-&lt;li>&lt;?php echo $item;?>&lt;/li>
-
-&lt;?php endforeach;?>
-&lt;/ul>
-
-&lt;/body>
-&lt;/html>
-</textarea>
-<p><strong>Note:</strong> You'll notice that in the example above we are using PHP's alternative syntax.  If you
-are not familiar with it you can read about it <a href="alternative_php.html">here</a>.</p>
-
-<h2>Returning views as data</h2>
-
-<p>There is a third <strong>optional</strong> parameter lets you change the behavior of the function so that it returns data as a string
-rather than sending it to your browser.  This can be useful if you want to process the data in some way.  If you
-set the parameter to <kbd>true</kbd> (boolean) it will return data.  The default behavior is <kbd>false</kbd>, which sends it
-to your browser.  Remember to assign it to a variable if you want the data returned:</p>
-
-<code>$string = $this->load->view('<var>myfile</var>', '', <kbd>true</kbd>);</code>

-<h1>Array Helper</h1>
-
-<p>The Array Helper file contains functions that assist in working with arrays.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('array');</code>
-
-<p>The following functions are available:</p>
-
-<h2>element()</h2>
-
-<p>Lets you fetch an item from an array.  The function tests whether the array index is set and whether it has a value.  If
-a value exists it is returned.  If a value does not exist it returns FALSE, or whatever you've specified as the default value via the third parameter.  Example:</p>
-
-<code>
-$array = array('color' => 'red', 'shape' => 'round', 'size' => '');<br />
-<br />
-// returns "red"<br />
-echo element('color', $array);<br />
-<br />
-// returns NULL<br />
-echo element('size', $array, NULL);
-</code>
-
-
-<h2>random_element()</h2>
-
-<p>Takes an array as input and returns a random element from it.  Usage example:</p>
-
-<code>$quotes = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I find that the harder I work, the more luck I seem to have. - Thomas Jefferson",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Don't stay in bed, unless you can make money in bed. - George Burns",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"We didn't lose the game; we just ran out of time. - Vince Lombardi",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"If everything seems under control, you're not going fast enough. - Mario Andretti",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Reality is merely an illusion, albeit a very persistent one. - Albert Einstein",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Chance favors the prepared mind - Louis Pasteur"<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo random_element($quotes);</code>
-
-
-<h2>elements()</h2>
-
-<p>Lets you fetch a number of items from an array.  The function tests whether each of the array indices is set.  If an index does not exist
-it is set to FALSE, or whatever you've specified as the default value via the third parameter.  Example:</p>
-
-<code>
-$array = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'radius' => '10',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'diameter' => '20'<br />
-);<br />
-<br />
-$my_shape = elements(array('color', 'shape', 'height'), $array);<br />
-</code>
-
-<p>The above will return the following array:</p>
-
-<code>
-array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'height' => FALSE<br />
-);
-</code>
-
-<p>You can set the third parameter to any default value you like:</p>
-
-<code>
-$my_shape = elements(array('color', 'shape', 'height'), $array, NULL);<br />
-</code>
-
-<p>The above will return the following array:</p>
-
-<code>
-array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'height' => NULL<br />
-);
-</code>
-
-<p>This is useful when sending the <kbd>$_POST</kbd> array to one of your Models.  This prevents users from
-sending additional POST data to be entered into your tables:</p>
-
-<code>
-$this->load->model('post_model');<br />
-<br />
-$this->post_model->update(elements(array('id', 'title', 'content'), $_POST));
-</code>
-
-<p>This ensures that only the id, title and content fields are sent to be updated.</p>

-<h1>CAPTCHA Helper</h1>
-
-<p>The CAPTCHA Helper file contains functions that assist in creating CAPTCHA images.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('captcha');</code>
-
-<p>The following functions are available:</p>
-
-<h2>create_captcha(<var>$data</var>)</h2>
-
-<p>Takes an array of information to generate the CAPTCHA as input and creates the image to your specifications, returning an array of associative data about the image.</p>
-
-<code>[array]<br />
-(<br />
-&nbsp;&nbsp;'image' => IMAGE TAG<br />
-&nbsp;&nbsp;'time'	=> TIMESTAMP (in microtime)<br />
-&nbsp;&nbsp;'word'	=> CAPTCHA WORD<br />
-)</code>
-
-	<p>The "image" is the actual image tag:
-<code>&lt;img src=&quot;http://example.com/captcha/12345.jpg&quot; width=&quot;140&quot; height=&quot;50&quot; /&gt;</code></p>
-
-	<p>The "time" is the micro timestamp used as the image name without the file
-	extension.  It will be a number like this:  1139612155.3422</p>
-
-	<p>The "word" is the word that appears in the captcha image, which if not
-	supplied to the function, will be a random string.</p>
-
-	<h3>Using the CAPTCHA helper</h3>
-
-	<p>Once loaded you can generate a captcha like this:</p>
-
-<code>$vals = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'word'		 => 'Random word',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'img_path'	 => './captcha/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'img_url'	 => 'http://example.com/captcha/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'font_path'	 => './path/to/fonts/texb.ttf',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'img_width'	 => '150',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'img_height' => 30,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'expiration' => 7200<br />
-&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$cap = create_captcha($vals);<br />
-echo $cap['image'];</code>
-
-	<ul>
-		<li>The captcha function requires the GD image library.</li>
-		<li>Only the img_path and img_url are required.</li>
-		<li>If a "word" is not supplied, the function will generate a random
-		ASCII string.  You might put together your own word library that
-		you can draw randomly from.</li>
-		<li>If you do not specify a path to a TRUE TYPE font, the native ugly GD
-		font will be used.</li>
-		<li>The "captcha" folder must be writable (666, or 777)</li>
-		<li>The "expiration" (in seconds) signifies how long an image will
-		remain in the captcha folder before it will be deleted.  The default
-		is two hours.</li>
-	</ul>
-
-	<h3>Adding a Database</h3>
-
-	<p>In order for the captcha function to prevent someone from submitting, you will need
-	to add the information returned from <kbd>create_captcha()</kbd> function to your database.
-	Then, when the data from the form is submitted by the user you will need to verify
-	that the data exists in the database and has not expired.</p>
-
-	<p>Here is a table prototype:</p>
-
-<code>CREATE TABLE captcha (<br />
-&nbsp;captcha_id bigint(13) unsigned NOT NULL auto_increment,<br />
-&nbsp;captcha_time int(10) unsigned NOT NULL,<br />
-&nbsp;ip_address varchar(16) default '0' NOT NULL,<br />
-&nbsp;word varchar(20) NOT NULL,<br />
-&nbsp;PRIMARY KEY `captcha_id` (`captcha_id`),<br />
-&nbsp;KEY `word` (`word`)<br />
-);</code>
-
-	<p>Here is an example of usage with a database.  On the page where the CAPTCHA will be shown you'll have something like this:</p>
-
-<code>$this-&gt;load-&gt;helper(&#x27;captcha&#x27;);<br />
-$vals = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&#x27;img_path&#x27;	 =&gt; &#x27;./captcha/&#x27;,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&#x27;img_url&#x27;	 =&gt; &#x27;http://example.com/captcha/&#x27;<br />

-<h1>Date Helper</h1>
-
-<p>The Date Helper file contains functions that help you work with dates.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('date');</code>
-
-
-<p>The following functions are available:</p>
-
-<h2>now()</h2>
-
-<p>Returns the current time as a Unix timestamp, referenced either to your server's local time or GMT, based on the "time reference"
-setting in your config file.  If you do not intend to set your master time reference to GMT (which you'll typically do if you
-run a site that lets each user set their own timezone settings) there is no benefit to using this function over PHP's time() function.
-</p>
-
-
-
-
-<h2>mdate()</h2>
-
-<p>This function is identical to PHPs <a href="http://www.php.net/date">date()</a> function, except that it lets you
-use MySQL style date codes, where each code letter is preceded with a percent sign:  %Y %m %d etc.</p>
-
-<p>The benefit of doing dates this way is that you don't have to worry about escaping any characters that
-are not date codes, as you would normally have to do with the date() function.  Example:</p>
-
-<code>$datestring = "Year: %Y Month: %m Day: %d - %h:%i %a";<br />
-$time = time();<br />
-<br />
-echo mdate($datestring, $time);</code>
-
-<p>If a timestamp is not included in the second parameter the current time will be used.</p>
-
-
-<h2>standard_date()</h2>
-
-<p>Lets you generate a date string in one of several standardized formats. Example:</p>
-
-<code>
-$format = 'DATE_RFC822';<br />
-$time = time();<br />
-<br />
-echo standard_date($format, $time);
-</code>
-
-<p>The first parameter must contain the format, the second parameter must contain the date as a Unix timestamp.</p>
-
-<p>Supported formats:</p>
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">
-	<tr>
-		<th>Constant</th>
-		<th>Description</th>
-		<th>Example</th>

-
-<h2>local_to_gmt()</h2>
-
-<p>Takes a Unix timestamp as input and returns it as GMT.  Example:</p>
-
-<code>$now = time();<br />
-<br />
-$gmt = local_to_gmt($now);</code>
-
-
-<h2>gmt_to_local()</h2>
-
-<p>Takes a Unix timestamp (referenced to GMT) as input, and converts it to a localized timestamp based on the
-timezone and Daylight Saving time submitted.  Example:</p>
-
-<code>
-$timestamp = '1140153693';<br />
-$timezone  = 'UM8';<br />
-$daylight_saving = TRUE;<br />
-<br />
-echo gmt_to_local($timestamp, $timezone, $daylight_saving);</code>
-
-<p><strong>Note:</strong> For a list of timezones see the reference at the bottom of this page.</p>
-
-<h2>mysql_to_unix()</h2>
-
-<p>Takes a MySQL Timestamp as input and returns it as Unix. Example:</p>
-
-<code>$mysql = '20061124092345';<br />
-<br />
-$unix = mysql_to_unix($mysql);</code>
-
-
-<h2>unix_to_human()</h2>
-
-<p>Takes a Unix timestamp as input and returns it in a human readable format with this prototype:</p>
-
-<code>YYYY-MM-DD HH:MM:SS AM/PM</code>
-
-<p>This can be useful if you need to display a date in a form field for submission.</p>
-
-<p>The time can be formatted with or without seconds, and it can be set to European or US format.  If only
-the timestamp is submitted it will return the time without seconds formatted for the U.S. Examples:</p>
-
-<code>$now = time();<br />
-<br />
-echo unix_to_human($now); // U.S. time, no seconds<br />
-<br />
-echo unix_to_human($now, TRUE, 'us'); // U.S. time with seconds<br />
-<br />
-echo unix_to_human($now, TRUE, 'eu'); // Euro time with seconds</code>
-
-
-<h2>human_to_unix()</h2>
-
-<p>The opposite of the above function.  Takes a "human" time as input and returns it as Unix.  This function is
-useful if you accept "human" formatted dates submitted via a form.  Returns FALSE (boolean) if
-the date string passed to it is not formatted as indicated above.  Example:</p>
-
-<code>$now = time();<br />
-<br />
-$human = unix_to_human($now);<br />
-<br />
-$unix = human_to_unix($human);</code>
-
-
-
-<h2>nice_date()</h2>
-
-<p>This function can take a number poorly-formed date formats and convert them into something useful. It also accepts well-formed dates.</p> 
-<p>The function will return a Unix timestamp by default. You can, optionally, pass a format string (the same type as the PHP date function accepts) as the second parameter. Example:</p>
-
-<code>$bad_time = 199605<br />
-<br />
-// Should Produce: 1996-05-01<br />
-$better_time = nice_date($bad_time,'Y-m-d');<br />
-<br />
-$bad_time = 9-11-2001<br />
-// Should Produce: 2001-09-11<br />
-$better_time = nice_date($human,'Y-m-d');</code>
-
-
-
-<h2>timespan()</h2>
-
-<p>Formats a unix timestamp so that is appears similar to this:</p>
-
-<code>1 Year, 10 Months, 2 Weeks, 5 Days, 10 Hours, 16 Minutes</code>
-
-<p>The first parameter must contain a Unix timestamp.  The second parameter must contain a
-timestamp that is greater that the first timestamp.  If the second parameter empty, the current time will be used.  The most common purpose
-for this function is to show how much time has elapsed from some point in time in the past to now.  Example:</p>
-
-<code>$post_date = '1079621429';<br />
-$now = time();<br />
-<br />
-echo timespan($post_date, $now);</code>
-
-<p class="important"><strong>Note:</strong> The text generated by this function is found in the following language file: language/&lt;your_lang&gt;/date_lang.php</p>
-
-
-<h2>days_in_month()</h2>
-
-<p>Returns the number of days in a given month/year. Takes leap years into account.  Example:</p>
-<code>echo days_in_month(06, 2005);</code>
-
-<p>If the second parameter is empty, the current year will be used.</p>
-<h2>timezones()</h2>
-<p> Takes a timezone reference (for a list of valid timezones, see the &quot;Timezone Reference&quot; below) and returns the number of hours offset from UTC.</p>
-<p><code>echo timezones('UM5');</code></p>
-<p>This function is useful when used with timezone_menu(). </p>
-<h2>timezone_menu()</h2>
-<p>Generates a pull-down menu of timezones, like this one:</p>
-
-<form action="#">
-<select name="timezones">
-<option value='UM12'>(UTC - 12:00) Enitwetok, Kwajalien</option>
-<option value='UM11'>(UTC - 11:00) Nome, Midway Island, Samoa</option>

-<option value='UP11'>(UTC + 11:00) Magadan, New Caledonia, Solomon Islands</option>
-<option value='UP12'>(UTC + 12:00) Auckland, Wellington, Fiji, Marshall Island</option>
-</select>
-</form>
-
-<p>This menu is useful if you run a membership site in which your users are allowed to set their local timezone value.</p>
-
-<p>The first parameter lets you set the "selected" state of the menu.  For example, to set Pacific time as the default you will do this:</p>
-
-<code>echo timezone_menu('UM8');</code>
-
-<p>Please see the timezone reference below to see the values of this menu.</p>
-
-<p>The second parameter lets you set a CSS class name for the menu.</p>
-
-<p class="important"><strong>Note:</strong> The text contained in the menu is found in the following language file: language/&lt;your_lang&gt;/date_lang.php</p>
-
-
-

-<h1>Directory Helper</h1>
-
-<p>The Directory Helper file contains functions that assist in working with directories.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('directory');</code>
-
-<p>The following functions are available:</p>
-
-<h2>directory_map('<var>source directory</var>')</h2>
-
-<p>This function reads the directory path specified in the first parameter
-and builds an array representation of it and all its contained files. Example:</p>
-
-<code>$map = directory_map('./mydirectory/');</code>
-
-<p class="important"><strong>Note:</strong> Paths are almost always relative to your main index.php file.</p>
-
-<p>Sub-folders contained within the directory will be mapped as well.  If you wish to control the recursion depth,
-you can do so using the second parameter (integer). A depth of 1 will only map the top level directory:</p>
-
-<code>$map = directory_map('./mydirectory/', 1);</code>
-
-<p>By default, hidden files will not be included in the returned array.  To override this behavior,
-you may set a third parameter to <var>true</var> (boolean):</p>
-
-<code>$map = directory_map('./mydirectory/', FALSE, TRUE);</code>
-
-<p>Each folder name will be an array index, while its contained files will be numerically indexed.
-Here is an example of a typical array:</p>
-
-<code>Array<br />
-(<br />
-&nbsp;&nbsp;&nbsp;[libraries] => Array<br />
-&nbsp;&nbsp;&nbsp;(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[0] => benchmark.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[1] => config.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[database] => Array<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[0] => active_record.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[1] => binds.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[2] => configuration.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[3] => connecting.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[4] => examples.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[5] => fields.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[6] => index.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[7] => queries.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[2] => email.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[3] => file_uploading.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[4] => image_lib.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[5] => input.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[6] => language.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[7] => loader.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[8] => pagination.html<br />

-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('file');</code>
-
-<p>The following functions are available:</p>
-
-<h2>read_file('<var>path</var>')</h2>
-
-<p>Returns the data contained in the file specified in the path.  Example:</p>
-
-<code>$string = read_file('./path/to/file.php');</code>
-
-<p>The path can be a relative or full server path.  Returns FALSE (boolean) on failure.</p>
-
-<p class="important"><strong>Note:</strong> The path is relative to your main site index.php file, NOT your controller or view files.
-CodeIgniter uses a front controller so paths are always relative to the main site index.</p>
-
-<p>If your server is running an open_basedir restriction this function
-might not work if you are trying to access a file above the calling script.</p>
-
-<h2>write_file('<var>path</var>', <kbd>$data</kbd>)</h2>
-
-<p>Writes data to the file specified in the path.  If the file does not exist the function will create it. Example:</p>
-
-<code>
-$data = 'Some file data';<br />
-<br />
-if ( ! write_file('./path/to/file.php', $data))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp; echo 'Unable to write the file';<br />

-}</code>
-
-<p>You can optionally set the write mode via the third parameter:</p>
-
-<code>write_file('./path/to/file.php', $data, <var>'r+'</var>);</code>
-
-<p>The default mode is <kbd>wb</kbd>.  Please see the <a href="http://php.net/fopen">PHP user guide</a> for mode options.</p>
-
-<p>Note: In order for this function to write data to a file its file permissions must be set such that it is writable (666, 777, etc.).
-If the file does not already exist, the directory containing it must be writable.</p>
-
-<p class="important"><strong>Note:</strong> The path is relative to your main site index.php file, NOT your controller or view files.
-CodeIgniter uses a front controller so paths are always relative to the main site index.</p>
-
-<h2>delete_files('<var>path</var>')</h2>
-
-<p>Deletes ALL files contained in the supplied path.  Example:</p>
-<code>delete_files('./path/to/directory/');</code>
-
-<p>If the second parameter is set to <kbd>true</kbd>, any directories contained within the supplied root path will be deleted as well. Example:</p>
-
-<code>delete_files('./path/to/directory/', TRUE);</code>
-
-<p class="important"><strong>Note:</strong> The files must be writable or owned by the system in order to be deleted.</p>
-
-<h2>get_filenames('<var>path/to/directory/</var>')</h2>
-
-<p>Takes a server path as input and returns an array containing the names of all files contained within it. The file path
-can optionally be added to the file names by setting the second parameter to TRUE.</p>
-
-<h2>get_dir_file_info('<var>path/to/directory/</var>', <kbd>$top_level_only</kbd> = TRUE)</h2>
-
-<p>Reads the specified directory and builds an array containing the filenames, filesize, dates, and permissions.  Sub-folders contained within the specified path are only read if forced
-	by sending the second parameter, <kbd>$top_level_only</kbd> to <samp>FALSE</samp>, as this can be an intensive operation.</p>
-
-<h2>get_file_info('<var>path/to/file</var>', <kbd>$file_information</kbd>)</h2>
-
-<p>Given a file and path, returns the name, path, size, date modified. Second parameter allows you to explicitly declare what information you want returned; options are: name, server_path, size, date, readable, writable, executable, fileperms.  Returns FALSE if the file cannot be found.</p>
-
-<p class="important"><strong>Note:</strong> The &quot;writable&quot; uses the PHP function is_writable() which is known to have issues on the IIS webserver. Consider using fileperms instead, which returns information from PHP's fileperms() function.</p>
-<h2>get_mime_by_extension('<var>file</var>')</h2>
-
-<p>Translates a file extension into a mime type based on config/mimes.php. Returns FALSE if it can't determine the type, or open the mime config file.</p>
-<p>
-<code>$file = &quot;somefile.png&quot;;<br />
-echo $file . ' is has a mime type of ' . get_mime_by_extension($file);</code>
-</p>
-<p class="critical"><strong>Note:</strong> This is not an accurate way of determining file mime types, and is here strictly as a convenience. It should not be  used for security.</p>
-
-<h2>symbolic_permissions(<kbd>$perms</kbd>)</h2>
-
-<p>Takes numeric permissions (such as is returned by <kbd>fileperms()</kbd> and returns standard symbolic notation of file permissions.</p>
-
-<code>echo symbolic_permissions(fileperms('./index.php'));<br />
-<br />
-// -rw-r--r--</code>
-
-<h2>octal_permissions(<kbd>$perms</kbd>)</h2>
-
-<p>Takes numeric permissions (such as is returned by <kbd>fileperms()</kbd> and returns a three character octal notation of file permissions.</p>
-
-<code>echo octal_permissions(fileperms('./index.php'));<br />
-<br />
-// 644</code>

-<h1>Form Helper</h1>
-
-<p>The Form Helper file contains functions that assist in working with forms.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('form');</code>
-
-<p>The following functions are available:</p>
-
-
-
-<h2>form_open()</h2>
-
-<p>Creates an opening form tag with a base URL <strong>built from your config preferences</strong>.  It will optionally let you
-add form attributes and hidden input fields, and will always add the attribute <kbd>accept-charset</kbd> based on the charset value in your config file.</p>
-
-<p>The main benefit of using this tag rather than hard coding your own HTML is that it permits your site to be more portable
-in the event your URLs ever change.</p>
-
-<p>Here's a simple example:</p>
-
-<code>echo form_open('email/send');</code>
-
-<p>The above example would create a form that points to your base URL plus the "email/send" URI segments, like this:</p>
-
-<code>&lt;form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send" /></code>
-
-<h4>Adding Attributes</h4>
-
-<p>Attributes can be added by passing an associative array to the second parameter, like this:</p>
-
-<code>
-$attributes = array('class' => 'email', 'id' => 'myform');<br />
-<br />
-echo form_open('email/send', $attributes);</code>
-
-<p>The above example would create a form similar to this:</p>
-
-<code>&lt;form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send" &nbsp;class="email" &nbsp;id="myform" /></code>
-
-<h4>Adding Hidden Input Fields</h4>
-
-<p>Hidden fields can be added by passing an associative array to the third parameter, like this:</p>
-
-<code>
-$hidden = array('username' => 'Joe', 'member_id' => '234');<br />
-<br />
-echo form_open('email/send', '', $hidden);</code>
-
-<p>The above example would create a form similar to this:</p>
-
-<code>&lt;form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send"><br />
-&lt;input type="hidden" name="username" value="Joe" /><br />
-&lt;input type="hidden" name="member_id" value="234" /></code>
-
-
-<h2>form_open_multipart()</h2>
-
-<p>This function is absolutely identical to the <dfn>form_open()</dfn> tag above except that it adds a multipart attribute,
-which is necessary if you would like to use the form to upload files with.</p>
-
-<h2>form_hidden()</h2>
-
-<p>Lets you generate hidden input fields.  You can either submit a name/value string to create one field:</p>
-
-<code>form_hidden('username', 'johndoe');<br />
-<br />
-// Would produce:<br /><br />
-&lt;input type="hidden" name="username" value="johndoe" /></code>
-
-<p>Or you can submit an associative array to create multiple fields:</p>
-
-<code>$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;=> 'John Doe',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'email' => 'john@example.com',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'url'&nbsp;&nbsp;&nbsp;=> 'http://example.com'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo form_hidden($data);<br />
-<br />
-// Would produce:<br /><br />
-&lt;input type="hidden" name="name" value="John Doe" /><br />
-&lt;input type="hidden" name="email" value="john@example.com" /><br />
-&lt;input type="hidden" name="url" value="http://example.com" /></code>
-
-
-
-
-<h2>form_input()</h2>
-
-<p>Lets you generate a standard text input field.  You can minimally pass the field name and value in the first
-and second parameter:</p>
-
-<code>echo form_input('username', 'johndoe');</code>
-
-<p>Or you can pass an associative array containing any data you wish your form to contain:</p>
-
-<code>$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'username',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'username',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'value'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'johndoe',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'maxlength'&nbsp;&nbsp;&nbsp;=> '100',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'size'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '50',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'style'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'width:50%',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo form_input($data);<br />
-<br />
-// Would produce:<br /><br />
-&lt;input type="text" name="username" id="username" value="johndoe" maxlength="100" size="50" style="width:50%" /></code>
-
-<p>If you would like your form to contain some additional data, like Javascript, you can pass it as a string in the
-third parameter:</p>
-
-<code>$js = 'onClick="some_function()"';<br />
-<br />
-echo form_input('username', 'johndoe', $js);</code>
-
-<h2>form_password()</h2>
-
-<p>This function is identical in all respects to the <dfn>form_input()</dfn> function above
-except that it uses the "password" input type.</p>
-
-<h2>form_upload()</h2>
-
-<p>This function is identical in all respects to the <dfn>form_input()</dfn> function above
-except that it uses the "file" input type, allowing it to be used to upload files.</p>
-
-<h2>form_textarea()</h2>
-
-<p>This function is identical in all respects to the <dfn>form_input()</dfn> function above
-except that it generates a "textarea" type. Note: Instead of the "maxlength" and "size" attributes in the above
-example, you will instead specify "rows" and "cols".</p>
-
-
-<h2>form_dropdown()</h2>
-
-<p>Lets you create a standard drop-down field.  The first parameter will contain the name of the field,
-the second parameter will contain an associative array of options, and the third parameter will contain the
-value you wish to be selected.  You can also pass an array of multiple items through the third parameter, and CodeIgniter will create a multiple select for you. Example:</p>
-
-<code>$options = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'small'&nbsp;&nbsp;=> 'Small Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'med'&nbsp;&nbsp;&nbsp;&nbsp;=> 'Medium Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'large'&nbsp;&nbsp; => 'Large Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'xlarge' => 'Extra Large Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$shirts_on_sale = array('small', 'large');<br />
-<br />
-echo form_dropdown('shirts', $options, 'large');<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;select name=&quot;shirts&quot;&gt;<br />
-&lt;option value=&quot;small&quot;&gt;Small Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;med&quot;&gt;Medium  Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;large&quot; selected=&quot;selected&quot;&gt;Large Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;xlarge&quot;&gt;Extra Large Shirt&lt;/option&gt;<br />
-&lt;/select&gt;<br />
-<br />
-echo form_dropdown('shirts', $options, $shirts_on_sale);<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;select name=&quot;shirts&quot; multiple=&quot;multiple&quot;&gt;<br />
-&lt;option value=&quot;small&quot; selected=&quot;selected&quot;&gt;Small Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;med&quot;&gt;Medium  Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;large&quot; selected=&quot;selected&quot;&gt;Large Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;xlarge&quot;&gt;Extra Large Shirt&lt;/option&gt;<br />
-&lt;/select&gt;</code>
-
-
-<p>If you would like the opening &lt;select> to contain additional data, like an <kbd>id</kbd> attribute or JavaScript, you can pass it as a string in the
-fourth parameter:</p>
-
-<code>$js = 'id="shirts" onChange="some_function();"';<br />
-<br />
-echo form_dropdown('shirts', $options, 'large', $js);</code>
-
-<p>If the array passed as $options is a multidimensional array, form_dropdown() will produce an &lt;optgroup&gt; with the array key as the label.</p>
-
-<h2>form_multiselect()</h2>
-
-<p>Lets you create a standard multiselect field.  The first parameter will contain the name of the field,
-the second parameter will contain an associative array of options, and the third parameter will contain the
-value or values you wish to be selected.  The parameter usage is identical to using <kbd>form_dropdown()</kbd> above,
-except of course that the name of the field will need to use POST array syntax, e.g. <samp>foo[]</samp>.</p>
-
-
-<h2>form_fieldset()</h2>
-
-<p>Lets you generate fieldset/legend fields.</p>
-<code>echo form_fieldset('Address Information');<br />
-echo &quot;&lt;p&gt;fieldset content here&lt;/p&gt;\n&quot;;<br />
-echo form_fieldset_close();
-<br />
-<br />
-// Produces<br />
-&lt;fieldset&gt;
-<br />
-&lt;legend&gt;Address Information&lt;/legend&gt;
-<br />
-&lt;p&gt;form content here&lt;/p&gt;
-<br />
-&lt;/fieldset&gt;</code>
-<p>Similar to other functions, you can submit an associative array in the second parameter if you prefer to set additional attributes. </p>
-<p><code>$attributes = array('id' =&gt; 'address_info', 'class' =&gt; 'address_info');<br />
-    echo form_fieldset('Address Information', $attributes);<br />
-echo &quot;&lt;p&gt;fieldset content here&lt;/p&gt;\n&quot;;<br />
-echo form_fieldset_close(); <br />
-<br />
-// Produces<br />
-&lt;fieldset id=&quot;address_info&quot; class=&quot;address_info&quot;&gt; <br />
-&lt;legend&gt;Address Information&lt;/legend&gt; <br />
-&lt;p&gt;form content here&lt;/p&gt; <br />
-&lt;/fieldset&gt;</code></p>
-<h2>form_fieldset_close()</h2>
-<p>Produces a closing &lt;/fieldset&gt; tag.  The only advantage to using this function is it permits you to pass data to it
-    which will be added below the tag.  For example:</p>
-<code>$string = &quot;&lt;/div&gt;&lt;/div&gt;&quot;;<br />
-<br />
-echo form_fieldset_close($string);<br />
-<br />
-// Would produce:<br />
-&lt;/fieldset&gt;<br />
-&lt;/div&gt;&lt;/div&gt;</code>
-<h2>form_checkbox()</h2>
-<p>Lets you generate a checkbox field. Simple example:</p>
-<code>echo form_checkbox('newsletter', 'accept', TRUE);<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;input type=&quot;checkbox&quot; name=&quot;newsletter&quot; value=&quot;accept&quot; checked=&quot;checked&quot; /&gt;</code>
-<p>The third parameter contains a boolean TRUE/FALSE to determine whether the box should be checked or not.</p>
-<p>Similar to the other form functions in this helper, you can also pass an array of attributes to the function:</p>
-
-<code>$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'newsletter',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'newsletter',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'value'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'accept',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'checked'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> TRUE,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'style'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'margin:10px',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo form_checkbox($data);<br />
-<br />
-// Would produce:<br /><br />
-&lt;input type="checkbox" name="newsletter" id="newsletter" value="accept" checked="checked" style="margin:10px" /></code>
-
-<p>As with other functions, if you would like the tag to contain  additional data, like JavaScript, you can pass it as a string in the
-fourth parameter:</p>
-
-<code>$js = 'onClick="some_function()"';<br />
-<br />
- echo form_checkbox('newsletter', 'accept', TRUE, $js)</code>
-
-
-<h2>form_radio()</h2>
-<p>This function is identical in all respects to the <dfn>form_checkbox()</dfn> function above except that it uses the "radio" input type.</p>
-
-
-<h2>form_submit()</h2>
-
-<p>Lets you generate a standard submit button. Simple example:</p>
-<code>echo form_submit('mysubmit', 'Submit Post!');<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;input type=&quot;submit&quot; name=&quot;mysubmit&quot; value=&quot;Submit Post!&quot; /&gt;</code>
-<p>Similar to other functions, you can submit an associative array in the first parameter if you prefer to set your own attributes.
-    The third parameter lets you add extra data to your form, like JavaScript.</p>
-<h2>form_label()</h2>
-<p>Lets you generate a &lt;label&gt;. Simple example:</p>
-<code>echo form_label('What is your Name', 'username');<br />
-<br />
-// Would produce:
-<br />
-&lt;label for=&quot;username&quot;&gt;What is your Name&lt;/label&gt;</code>
-<p>Similar to other functions, you can submit an associative array in the third parameter if you prefer to set additional attributes.    </p>
-<p><code>$attributes = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'class' =&gt; 'mycustomclass',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'style' =&gt; 'color: #000;',<br />
-);<br />
-    echo form_label('What is your Name', 'username', $attributes);<br />
-        <br />
-// Would produce: <br />
-&lt;label for=&quot;username&quot; class=&quot;mycustomclass&quot; style=&quot;color: #000;&quot;&gt;What is your Name&lt;/label&gt;</code></p>
-<h2>form_reset()</h2>
-
-<p>Lets you generate a standard reset button. Use is identical to <dfn>form_submit()</dfn>.</p>
-
-<h2>form_button()</h2>
-
-<p>Lets you generate a standard button element. You can minimally pass the button name and content in the first and second parameter:</p>
-<code>
-echo form_button('name','content');<br />
-<br />
-// Would produce<br />
-&lt;button name="name" type="button"&gt;Content&lt;/button&gt;
-</code>
-
-Or you can pass an associative array containing any data you wish your form to contain:
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'button',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'id' => 'button',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'value' => 'true',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'type' => 'reset',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'content' => 'Reset'<br />
-);<br />
-<br />
-echo form_button($data);<br />
-<br />
-// Would produce:<br />
-&lt;button name="button" id="button" value="true" type="reset"&gt;Reset&lt;/button&gt;
-</code>
-
-If you would like your form to contain some additional data, like JavaScript, you can pass it as a string in the third parameter:
-<code>
-$js = 'onClick="some_function()"';<br /><br />
-echo form_button('mybutton', 'Click Me', $js);
-</code>
-
-
-<h2>form_close()</h2>
-
-<p>Produces a closing &lt;/form> tag.  The only advantage to using this function is it permits you to pass data to it
-which will be added below the tag.  For example:</p>
-
-<code>$string = "&lt;/div>&lt;/div>";<br />
-<br />
-echo form_close($string);<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;/form><br />
-&lt;/div>&lt;/div></code>
-
-
-
-
-
-<h2>form_prep()</h2>
-
-<p>Allows you to safely use HTML and characters such as quotes within form elements without breaking out of the form.  Consider this example:</p>
-
-<code>$string = 'Here is a string containing <strong>"quoted"</strong> text.';<br />
-<br />
-&lt;input type="text" name="myform" value="<var>$string</var>" /></code>
-
-<p>Since the above string contains a set of quotes it will cause the form to break.
-The form_prep function converts HTML so that it can be used safely:</p>
-
-<code>&lt;input type="text" name="myform" value="<var>&lt;?php echo form_prep($string); ?></var>" /></code>
-
-<p class="important"><strong>Note:</strong> If you use any of the form helper functions listed in this page the form
-values will be prepped automatically, so there is no need to call this function. Use it only if you are
-creating your own form elements.</p>
-
-
-<h2>set_value()</h2>
-
-<p>Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function.
-The second (optional) parameter allows you to set a default value for the form. Example:</p>
-
-<code>&lt;input type="text" name="quantity" value="<dfn>&lt;?php echo set_value('quantity', '0'); ?></dfn>" size="50" /></code>
-
-<p>The above form will show "0" when loaded for the first time.</p>
-
-<h2>set_select()</h2>
-
-<p>If you use a <dfn>&lt;select></dfn> menu, this function permits you to display the menu item that was selected.  The first parameter
-must contain the name of the select menu, the second parameter must contain the value of
-each item, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE).</p>
-
-<p>Example:</p>
-
-<code>
-&lt;select name="myselect"><br />
-&lt;option value="one" <dfn>&lt;?php echo  set_select('myselect', 'one', TRUE); ?></dfn> >One&lt;/option><br />
-&lt;option value="two" <dfn>&lt;?php echo  set_select('myselect', 'two'); ?></dfn> >Two&lt;/option><br />
-&lt;option value="three" <dfn>&lt;?php echo  set_select('myselect', 'three'); ?></dfn> >Three&lt;/option><br />
-&lt;/select>
-</code>

-&lt;input type="checkbox" name="mycheck" value="2" <dfn>&lt;?php echo set_checkbox('mycheck', '2'); ?></dfn> /></code>
-
-
-<h2>set_radio()</h2>

-<h1>HTML Helper</h1>
-
-<p>The HTML Helper file contains functions that assist in working with HTML.</p>
-
-<ul>
-	<li><a href="#br">br()</a></li>
-	<li><a href="#heading">heading()</a></li>
-	<li><a href="#img">img()</a></li>
-	<li><a href="#link_tag">link_tag()</a></li>
-	<li><a href="#nbs">nbs()</a></li>
-	<li><a href="#ol_and_ul">ol() and ul()</a></li>
-	<li><a href="#meta">meta()</a></li>
-	<li><a href="#doctype">doctype()</a></li>
-</ul>
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('html');</code>
-
-<p>The following functions are available:</p>
-
-<h2><a name="br"></a>br()</h2>
-<p>Generates line break tags (&lt;br />) based on the number you submit. Example:</p>
-<code>echo br(3);</code>
-<p>The above would produce: &lt;br />&lt;br />&lt;br /></p>
-
-<h2><a name="heading"></a>heading()</h2>
-<p>Lets you create HTML &lt;h1> tags.  The first parameter will contain the data, the
-second the size of the heading.  Example:</p>
-<code>echo heading('Welcome!', 3);</code>
-<p>The above would produce:  &lt;h3>Welcome!&lt;/h3></p>
-
-<p>Additionally, in order to add attributes to the heading tag such as HTML classes, ids or inline styles, a third parameter is available.</p>
-<code>echo heading('Welcome!', 3, 'class="pink"')</code>
-<p>The above code produces: &lt;h3 class="pink">Welcome!<&lt;h3></p>
-
-
-<h2><a name="img"></a>img()</h2>
-<p>Lets you create HTML &lt;img /&gt; tags.  The first parameter  contains the image source. Example:</p>
-<code>echo img('images/picture.jpg');<br />
-// gives &lt;img src=&quot;http://site.com/images/picture.jpg&quot; /&gt;</code>
-<p>There is an optional second parameter that is a TRUE/FALSE value that specifics if the src should have the page specified by $config['index_page'] added to the address it creates. Presumably, this would be if you were using a media controller.</p>
-<p><code>echo img('images/picture.jpg', TRUE);<br />
-// gives &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; alt=&quot;&quot; /&gt;</code></p>
-<p>Additionally, an associative array can be passed to the img() function for complete control over all attributes and values. If an alt attribute is not provided, CodeIgniter will generate an empty string.</p>
-<p><code> $image_properties = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'src' =&gt; 'images/picture.jpg',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'alt' =&gt; 'Me, demonstrating how to eat 4 slices of pizza at one time',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' =&gt; 'post_images',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'width' =&gt; '200',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'height' =&gt; '200',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' =&gt; 'That was quite a night',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'lightbox',<br />
-	);<br />
-	<br />
-	img($image_properties);<br />
-	// &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; alt=&quot;Me, demonstrating how to eat 4 slices of pizza at one time&quot; class=&quot;post_images&quot; width=&quot;200&quot; height=&quot;200&quot; title=&quot;That was quite a night&quot; rel=&quot;lightbox&quot; /&gt;</code></p>
-
-<h2><a name="link_tag"></a>link_tag()</h2>
-<p>Lets you create HTML &lt;link /> tags.  This is useful for stylesheet links, as well as other links. The parameters are href, with optional rel, type, title, media and index_page. index_page is a TRUE/FALSE value that specifics if the href should have the page specified by $config['index_page'] added to the address it creates.<code>
-echo link_tag('css/mystyles.css');<br />
-// gives &lt;link href=&quot;http://site.com/css/mystyles.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; /&gt;</code></p>
-<p>Further examples:</p>
-
-<code>
-	echo link_tag('favicon.ico', 'shortcut icon', 'image/ico');<br />
-	// &lt;link href=&quot;http://site.com/favicon.ico&quot; rel=&quot;shortcut icon&quot; type=&quot;image/ico&quot; /&gt;
-	<br />
-	<br />
-	echo link_tag('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');<br />
-	// &lt;link href=&quot;http://site.com/feed&quot; rel=&quot;alternate&quot; type=&quot;application/rss+xml&quot; title=&quot;My RSS Feed&quot; /&gt; </code>
-<p>Additionally, an associative array can be passed to the link() function for complete control over all attributes and values.</p>
-<p><code>
-	$link = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'href' =&gt; 'css/printer.css',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'stylesheet',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'text/css',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'media' =&gt; 'print'<br />
-	);<br />
-	<br />
-	echo link_tag($link);<br />
-	// &lt;link href=&quot;http://site.com/css/printer.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;print&quot; /&gt;</code></p>
-
-<h2><a name="nbs"></a>nbs()</h2>
-<p>Generates non-breaking spaces (&amp;nbsp;) based on the number you submit. Example:</p>
-<code>echo nbs(3);</code>
-<p>The above would produce: &amp;nbsp;&amp;nbsp;&amp;nbsp;</p>
-
-<h2><a name="ol_and_ul"></a>ol()&nbsp; and&nbsp; ul()</h2>
-
-<p>Permits you to generate ordered or unordered HTML lists from simple or multi-dimensional arrays. Example:</p>
-
-<code>
-$this->load->helper('html');<br />
-<br />
-$list = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'yellow'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$attributes = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo ul($list, $attributes);<br />
-</code>
-
-<p>The above code will produce this:</p>
-
-<code>
-&lt;ul&nbsp;class="boldlist"&nbsp;id="mylist"><br />
-&nbsp;&nbsp;&lt;li>red&lt;/li><br />
-&nbsp;&nbsp;&lt;li>blue&lt;/li><br />
-&nbsp;&nbsp;&lt;li>green&lt;/li><br />
-&nbsp;&nbsp;&lt;li>yellow&lt;/li><br />
-&lt;/ul>
-</code>
-
-<p>Here is a more complex example, using a multi-dimensional array:</p>
-
-<code>
-$this->load->helper('html');<br />
-<br />
-$attributes = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$list = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'colors' => array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'shapes' => array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'round', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'square',<br />

-<h2><a name="meta"></a>meta()</h2>
-
-<p>Helps you generate meta tags.  You can pass strings to the function, or simple arrays, or multidimensional ones. Examples:</p>
-
-<code>
-echo meta('description', 'My Great site');<br />
-// Generates:  &lt;meta name="description" content="My Great Site" /><br />
-<br /><br />
-
-echo meta('Content-type', 'text/html; charset=utf-8', 'equiv'); // Note the third parameter.  Can be "equiv" or "name"<br />
-// Generates:  &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" /><br />
-
-<br /><br />
-
-echo meta(array('name' => 'robots', 'content' => 'no-cache'));<br />
-// Generates:  &lt;meta name="robots" content="no-cache" /><br />
-
-<br /><br />
-
-$meta = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'robots', 'content' => 'no-cache'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'description', 'content' => 'My Great Site'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'keywords', 'content' => 'love, passion, intrigue, deception'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'robots', 'content' => 'no-cache'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'Content-type', 'content' => 'text/html; charset=utf-8', 'type' => 'equiv')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo meta($meta);
-<br />
-// Generates:  <br />
-// &lt;meta name="robots" content="no-cache" /><br />
-// &lt;meta name="description" content="My Great Site" /><br />
-// &lt;meta name="keywords" content="love, passion, intrigue, deception" /><br />
-// &lt;meta name="robots" content="no-cache" /><br />
-// &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" />
-</code>
-
-
-<h2><a name="doctype"></a>doctype()</h2>
-
-<p>Helps you generate document type declarations, or DTD's. XHTML 1.0 Strict is used by default, but many doctypes are available.</p>
-
-<code>
-echo doctype();<br />
-// &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt;<br />

-echo doctype('html4-trans');<br />
-// &lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"&gt;

-<h1>Smiley Helper</h1>
-
-<p>The Smiley Helper file contains functions that let you manage smileys (emoticons).</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('smiley');</code>
-
-<h2>Overview</h2>
-
-<p>The Smiley helper has a renderer that takes plain text simileys, like <dfn>:-)</dfn> and turns
-them into a image representation, like <img src="../images/smile.gif" width="19" height="19" border="0" alt="smile!" /></p>
-
-<p>It also lets you display a set of smiley images that when clicked will be inserted into a form field.
-For example, if you have a blog that allows user commenting you can show the smileys next to the comment form.
-Your users can click a desired smiley and with the help of some JavaScript it will be placed into the form field.</p>
-
-
-
-<h2>Clickable Smileys Tutorial</h2>
-
-<p>Here is an example demonstrating how you might create a set of clickable smileys next to a form field. This example
-requires that you first download and install the smiley images, then create a controller and the View as described.</p>
-
-<p class="important"><strong>Important:</strong> Before you begin, please <a href="http://codeigniter.com/download_files/smileys.zip">download the smiley images</a> and put them in
-a publicly accessible place on your server.  This helper also assumes you have the smiley replacement array located at
-<dfn>application/config/smileys.php</dfn></p>
-
-
-<h3>The Controller</h3>
-
-<p>In your <dfn>application/controllers/</dfn> folder, create a file called <kbd>smileys.php</kbd> and place the code below in it.</p>
-
-<p><strong>Important:</strong> Change the URL in the <dfn>get_clickable_smileys()</dfn> function below so that it points to
-your <dfn>smiley</dfn> folder.</p>
-
-<p>You'll notice that in addition to the smiley helper we are using the <a href="../libraries/table.html">Table Class</a>.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="25">
-&lt;?php
-
-class Smileys extends CI_Controller {
-
-	function __construct()
-	{
-		parent::__construct();
-	}
-
-	function index()
-	{
-		$this->load->helper('smiley');
-		$this->load->library('table');
-
-		$image_array = get_clickable_smileys('http://example.com/images/smileys/', 'comments');
-
-		$col_array = $this->table->make_columns($image_array, 8);
-
-		$data['smiley_table'] = $this->table->generate($col_array);
-
-		$this->load->view('smiley_view', $data);
-	}
-
-}
-?&gt;
-</textarea>
-
-<p>In your <dfn>application/views/</dfn> folder, create a file called <kbd>smiley_view.php</kbd> and place this code in it:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="20">
-&lt;html>
-&lt;head>
-&lt;title>Smileys&lt;/title>
-
-&lt;?php echo smiley_js(); ?>
-
-&lt;/head>
-&lt;body>
-
-&lt;form name="blog">
-&lt;textarea name="comments" id="comments" cols="40" rows="4">&lt;/textarea>
-&lt;/form>
-
-&lt;p>Click to insert a smiley!&lt;/p>
-
-&lt;?php echo $smiley_table; ?>
-
-&lt;/body>
-&lt;/html>
-</textarea>
-
-
-<p>When you have created the above controller and view, load it by visiting <dfn>http://www.example.com/index.php/smileys/</dfn></p>
-
-
-<h3>Field Aliases</h3>
-
-<p>When making changes to a view it can be inconvenient to have the field id in the controller. To work around this,
-you can give your smiley links a generic name that will be tied to a specific id in your view.</p>
-<code>$image_array = get_smiley_links("http://example.com/images/smileys/", "comment_textarea_alias");</code>
-
-<p>To map the alias to the field id, pass them both into the smiley_js function:</p>
-<code>$image_array = smiley_js("comment_textarea_alias", "comments");</code>
-
-
-<h1>Function Reference</h1>
-
-<h2>get_clickable_smileys()</h2>
-
-<p>Returns an array containing your smiley images wrapped in a clickable link.  You must supply the URL to your smiley folder
-and a field id or field alias.</p>
-
-<code>$image_array = get_smiley_links("http://example.com/images/smileys/", "comment");</code>
-<p class="important">Note: Usage of this function without the second parameter, in combination with js_insert_smiley has been deprecated.</p>
-
-
-<h2>smiley_js()</h2>
-
-<p>Generates the JavaScript that allows the images to be clicked and inserted into a form field.
-If you supplied an alias instead of an id when generating your smiley links, you need to pass the
-alias and corresponding form id into the function.
-This function is designed to be placed into the &lt;head&gt; area of your web page.</p>
-
-<code>&lt;?php echo smiley_js(); ?&gt;</code>
-<p class="important">Note: This function replaces js_insert_smiley, which has been deprecated.</p>
-
-
-<h2>parse_smileys()</h2>
-
-<p>Takes a string of text as input and replaces any contained plain text smileys into the image
-equivalent.  The first parameter must contain your string, the second must contain  the URL to your smiley folder:</p>
-
-<code>
-$str = 'Here are some simileys: :-)  ;-)';
-
-$str = parse_smileys($str, "http://example.com/images/smileys/");
-
-echo $str;
-</code>

-<h1>String Helper</h1>
-
-<p>The String Helper file contains functions that assist in working with strings.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('string');</code>
-
-<p>The following functions are available:</p>
-
-<h2>random_string()</h2>
-
-<p>Generates a random string based on the type and length you specify.  Useful for creating passwords or generating random hashes.</p>
-
-<p>The first parameter specifies the type of string, the second parameter specifies the length.  The following choices are available:</p>
-
- alpha, alunum, numeric, nozero, unique, md5, encrypt and sha1
-<ul>
-	<li><strong>alpha</strong>:&nbsp; A string with lower and uppercase letters only.</li>
-	<li><strong>alnum</strong>:&nbsp; Alpha-numeric string with lower and uppercase characters.</li>
-	<li><strong>numeric</strong>:&nbsp; Numeric string.</li>
-	<li><strong>nozero</strong>:&nbsp; Numeric string with no zeros.</li>
-	<li><strong>unique</strong>:&nbsp; Encrypted with MD5 and uniqid(). Note: The length parameter is not available for this type.
-	Returns a fixed length 32 character string.</li>
-	<li><strong>sha1</strong>:&nbsp; An encrypted random number based on <kbd>do_hash()</kbd> from the <a href="security_helper.html">security helper</a>.</li>
-</ul>
-
-<p>Usage example:</p>
-
-<code>echo random_string('alnum', 16);</code>
-
-
-<h2>increment_string()</h2>
-
-<p>Increments a string by appending a number to it or increasing the number. Useful for creating "copies" or a file or duplicating database content which has unique titles or slugs.</p>
-
-<p>Usage example:</p>
-
-<code>echo increment_string('file', '_'); // "file_1"<br />
-echo increment_string('file', '-', 2); // "file-2"<br />
-echo increment_string('file-4'); // "file-5"<br /></code>
-
-
-<h2>alternator()</h2>
-
-<p>Allows two or more items to be alternated between, when cycling through a loop.  Example:</p>
-
-<code>for ($i = 0; $i < 10; $i++)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo alternator('string one', 'string two');<br />
-}<br />
-</code>
-
-<p>You can add as many parameters as you want, and with each iteration of your loop the next item will be returned.</p>
-
-<code>for ($i = 0; $i < 10; $i++)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo alternator('one', 'two', 'three', 'four', 'five');<br />
-}<br />
-</code>
-
-<p><strong>Note:</strong> To use multiple separate calls to this function simply call the function with no arguments to re-initialize.</p>
-
-
-
-<h2>repeater()</h2>
-<p>Generates repeating copies of the data you submit. Example:</p>
-<code>$string = "\n";<br />
-echo repeater($string, 30);</code>
-
-<p>The above would generate 30 newlines.</p>
-<h2>reduce_double_slashes()</h2>
-<p>Converts double slashes in a string to a single slash, except those found in http://. Example: </p>
-<code>$string = &quot;http://example.com//index.php&quot;;<br />
-echo reduce_double_slashes($string); // results in &quot;http://example.com/index.php&quot;</code>
-<h2>trim_slashes()</h2>
-<p>Removes any leading/trailing slashes from a string. Example:<br />
-	<br />
-	<code>$string = &quot;/this/that/theother/&quot;;<br />
-echo trim_slashes($string); // results in this/that/theother</code></p>
-
-
-<h2>reduce_multiples()</h2>
-<p>Reduces multiple instances of a particular character occuring directly after each other. Example:</p>
-<code>
-$string="Fred, Bill,, Joe, Jimmy";<br />
-$string=reduce_multiples($string,","); //results in "Fred, Bill, Joe, Jimmy"
-</code>
-<p>The function accepts the following parameters:
-<code>reduce_multiples(string: text to search in, string: character to reduce, boolean: whether to remove the character from the front and end of the string)</code>
-
-The first parameter contains the string in which you want to reduce the multiplies. The second parameter contains the character you want to have reduced.
-The third parameter is FALSE by default; if set to TRUE it will remove occurences of the character at the beginning and the end of the string. Example:
-
-<code>
-$string=",Fred, Bill,, Joe, Jimmy,";<br />
-$string=reduce_multiples($string, ", ", TRUE); //results in "Fred, Bill, Joe, Jimmy"
-</code>
-</p>
-
-<h2>quotes_to_entities()</h2>
-<p>Converts single and double quotes in a string to the corresponding HTML entities. Example:</p>
-<code>$string="Joe's \"dinner\"";<br />
-$string=quotes_to_entities($string); //results in "Joe&amp;#39;s &amp;quot;dinner&amp;quot;"
-</code>
-
-<h2>strip_quotes()</h2>
-<p>Removes single and double quotes from a string. Example:</p>
-<code>$string="Joe's \"dinner\"";<br />
-$string=strip_quotes($string); //results in "Joes dinner"
-</code>

-<h1>Text Helper</h1>
-
-<p>The Text Helper file contains functions that assist in working with text.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('text');</code>
-
-<p>The following functions are available:</p>
-
-
-<h2>word_limiter()</h2>
-
-<p>Truncates a string to the number of <strong>words</strong> specified.  Example:</p>
-
-<code>
-$string = "Here is a nice text string consisting of eleven words.";<br />
-<br />
-$string = word_limiter($string, 4);<br /><br />
-
-// Returns:  Here is a nice&#8230;
-</code>
-
-<p>The third parameter is an optional suffix added to the string.  By default it adds an ellipsis.</p>
-
-
-<h2>character_limiter()</h2>
-
-<p>Truncates a string to the number of <strong>characters</strong> specified.  It maintains the integrity
-of words so the character count may be slightly more or less then what you specify. Example:</p>
-
-<code>
-$string = "Here is a nice text string consisting of eleven words.";<br />
-<br />
-$string = character_limiter($string, 20);<br /><br />
-
-// Returns:  Here is a nice text string&#8230;
-</code>
-
-<p>The third parameter is an optional suffix added to the string, if undeclared this helper uses an ellipsis.</p>
-
-
-
-<h2>ascii_to_entities()</h2>
-
-<p>Converts ASCII values to character entities, including high ASCII and MS Word characters that can cause problems when used in a web page,
-so that they can be shown consistently regardless of browser settings or stored reliably in a database.
-There is some dependence on your server's supported character sets, so it may not be 100% reliable in all cases, but for the most
-part it should correctly identify characters outside the normal range (like accented characters). Example:</p>
-
-<code>$string = ascii_to_entities($string);</code>
-
-
-<h2>entities_to_ascii()</h2>
-
-<p>This function does the opposite of the previous one; it turns character entities back into ASCII.</p>
-
-<h2>convert_accented_characters()</h2>
-
-<p>Transliterates high ASCII characters to low ASCII equivalents, useful when non-English characters need to be used where only standard ASCII characters are safely used, for instance, in URLs.</p>
-
-<code>$string = convert_accented_characters($string);</code>
-
-<p>This function uses a companion config file <dfn>application/config/foreign_chars.php</dfn> to define the to and from array for transliteration.</p>
-
-<h2>word_censor()</h2>
-
-<p>Enables you to censor words within a text string.  The first parameter will contain the original string.  The
-second will contain an array of words which you disallow.  The third (optional) parameter can contain a replacement value
-for the words.  If not specified they are replaced with pound signs: ####.  Example:</p>
-
-<code>
-$disallowed = array('darn', 'shucks', 'golly', 'phooey');<br />
-<br />
-$string = word_censor($string, $disallowed, 'Beep!');</code>
-
-
-<h2>highlight_code()</h2>
-
-<p>Colorizes a string of code (PHP, HTML, etc.).  Example:</p>
-
-<code>$string = highlight_code($string);</code>
-
-<p>The function uses PHP's highlight_string() function, so the colors used are the ones specified in your php.ini file.</p>
-
-
-<h2>highlight_phrase()</h2>
-
-<p>Will highlight a phrase within a text string.  The first parameter will contain the original string, the second will
-contain the phrase you wish to highlight.  The third and fourth parameters will contain the opening/closing HTML tags
-you would like the phrase wrapped in.  Example:</p>
-
-<code>
-$string = "Here is a nice text string about nothing in particular.";<br />
-<br />
-$string = highlight_phrase($string, "nice text", '&lt;span style="color:#990000">', '&lt;/span>');
-</code>
-
-<p>The above text returns:</p>
-
-<p>Here is a <span style="color:#990000">nice text</span> string about nothing in particular.</p>
-
-
-
-<h2>word_wrap()</h2>
-
-<p>Wraps text at the specified <strong>character</strong> count while maintaining complete words.  Example:</p>
-
-<code>$string = "Here is a simple string of text that will help us demonstrate this function.";<br />
-<br />
-echo word_wrap($string, 25);<br />
-<br />
-// Would produce:<br />
-<br />
-Here is a simple string<br />
-of text that will help<br />
-us demonstrate this<br />
-function</code>
-
-<h2>ellipsize()</h2>
-
-<p>This function will strip tags from a string, split it at a defined maximum length, and insert an ellipsis.</p>
-<p>The first parameter is the string to ellipsize, the second is the number of characters in the final string. The third parameter is where in the string the ellipsis should appear from 0 - 1, left to right.  For example.  a value of 1 will place the ellipsis at the right of the string, .5 in the middle, and 0 at the left.</p>
-<p>An optional forth parameter is the kind of ellipsis.  By default, <samp>&amp;hellip;</samp> will be inserted.</p>
-
-<code>$str = 'this_string_is_entirely_too_long_and_might_break_my_design.jpg';<br />
-<br />
-echo ellipsize($str, 32, .5);</code>
-
-Produces:
-
-<code>this_string_is_e&hellip;ak_my_design.jpg</code>

-<h1>URL Helper</h1>
-
-<p>The URL Helper file contains functions that assist in working with URLs.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('url');</code>
-
-<p>The following functions are available:</p>
-
-<h2>site_url()</h2>
-
-<p>Returns your site URL, as specified in your config file.  The index.php file (or whatever you have set as your
-site <dfn>index_page</dfn> in your config file) will be added to the URL, as will any URI segments you pass to the function, and the <dfn>url_suffix</dfn> as set in your config file.</p>
-
-<p>You are encouraged to use this function any time you need to generate a local URL so that your pages become more portable
-in the event your URL changes.</p>
-
-<p>Segments can be optionally passed to the function as a string or an array.  Here is a string example:</p>
-
-<code>echo site_url("news/local/123");</code>
-
-<p>The above example would return something like: http://example.com/index.php/news/local/123</p>
-
-<p>Here is an example of segments passed as an array:</p>
-
-<code>
-$segments = array('news', 'local', '123');<br />
-<br />
-echo site_url($segments);</code>
-
-
-<h2>base_url()</h2>
-<p>Returns your site base URL, as specified in your config file.  Example:</p>
-<code>echo base_url();</code>
-
-<p>This function returns the same thing as site_url, without the <dfn>index_page</dfn> or <dfn>url_suffix</dfn> being appended.</p>
-
-<p>Also like site_url, you can supply segments as a string or an array.  Here is a string example:</p>
-
-<code>echo base_url("blog/post/123");</code>
-
-<p>The above example would return something like: http://example.com/blog/post/123</p>
-
-<p>This is useful because unlike site_url(), you can supply a string to a file, such as an image or stylesheet.  For example:</p>
-
-<code>echo base_url("images/icons/edit.png");</code>
-
-<p>This would give you something like: http://example.com/images/icons/edit.png</p>
-
-
-<h2>current_url()</h2>
-<p>Returns the full URL (including segments) of the page being currently viewed.</p>
-
-
-<h2>uri_string()</h2>
-<p>Returns the URI segments of any page that contains this function.  For example, if your URL was this:</p>
-<code>http://some-site.com/blog/comments/123</code>
-
-<p>The function would return:</p>
-<code>/blog/comments/123</code>
-
-
-<h2>index_page()</h2>
-<p>Returns your site "index" page, as specified in your config file.  Example:</p>
-<code>echo index_page();</code>
-
-
-
-<h2>anchor()</h2>
-
-<p>Creates a standard HTML anchor link based on your local site URL:</p>
-
-<code>&lt;a href="http://example.com">Click Here&lt;/a></code>
-
-<p>The tag has three optional parameters:</p>
-
-<code>anchor(<var>uri segments</var>, <var>text</var>, <var>attributes</var>)</code>
-
-<p>The first parameter can contain any segments you wish appended to the URL.  As with the <dfn>site_url()</dfn> function above,
-segments can be a string or an array.</p>
-
-<p><strong>Note:</strong>&nbsp; If you are building links that are internal to your application do not include the base URL (http://...).  This
-will be added automatically from the information specified in your config file. Include only the URI segments you wish appended to the URL.</p>
-
-<p>The second segment is the text you would like the link to say.  If you leave it blank, the URL will be used.</p>
-
-<p>The third parameter can contain a list of attributes you would like added to the link.  The attributes can be a simple string or an associative array.</p>
-
-<p>Here are some examples:</p>
-
-<code>echo anchor('news/local/123', 'My News', 'title="News title"');</code>
-
-<p>Would produce: &lt;a href="http://example.com/index.php/news/local/123" title="News title">My News&lt;/a></p>
-
-<code>echo anchor('news/local/123', 'My News', array('title' => 'The best news!'));</code>
-
-<p>Would produce: &lt;a href="http://example.com/index.php/news/local/123" title="The best news!">My News&lt;/a></p>
-
-
-<h2>anchor_popup()</h2>
-
-<p>Nearly identical to the <dfn>anchor()</dfn> function except that it opens the URL in a new window.
-
-You can specify JavaScript window attributes in the third parameter to control how the window is opened. If
-the third parameter is not set it will simply open a new window with your own browser settings.  Here is an example
-with attributes:</p>
-
-<code>
-
-$atts = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'width'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '800',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'height'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '600',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'scrollbars' => 'yes',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'status'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'yes',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'resizable'&nbsp;&nbsp;=> 'yes',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'screenx'&nbsp;&nbsp;&nbsp;&nbsp;=> '0',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'screeny'&nbsp;&nbsp;&nbsp;&nbsp;=> '0'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo anchor_popup('news/local/123', 'Click Me!', $atts);</code>
-
-<p>Note: The above attributes are the function defaults so you only need to set the ones that are different from what you need.
-If you want the function to use all of its defaults simply pass an empty array in the third parameter:</p>
-
-<code>echo anchor_popup('news/local/123', 'Click Me!', array());</code>
-
-
-<h2>mailto()</h2>
-
-<p>Creates a standard HTML email link.  Usage example:</p>
-
-<code>echo mailto('me@my-site.com', 'Click Here to Contact Me');</code>
-
-<p>As with the <dfn>anchor()</dfn> tab above, you can set attributes using the third parameter.</p>
-
-
-<h2>safe_mailto()</h2>
-
-<p>Identical to the above function except it writes an obfuscated version of the mailto tag using ordinal numbers
-written with JavaScript to help prevent the email address from being harvested by spam bots.</p>
-
-
-<h2>auto_link()</h2>
-
-<p>Automatically turns URLs and email addresses contained in a string into links.  Example:</p>
-
-<code>$string = auto_link($string);</code>
-
-<p>The second parameter determines whether URLs and emails are converted or just one or the other.  Default behavior is both
-if the parameter is not specified.  Email links are encoded as safe_mailto() as shown above.</p>
-
-<p>Converts only URLs:</p>
-<code>$string = auto_link($string, 'url');</code>
-
-<p>Converts only Email addresses:</p>
-<code>$string = auto_link($string, 'email');</code>
-
-<p>The third parameter determines whether links are shown in a new window.  The value can be TRUE or FALSE (boolean):</p>
-<code>$string = auto_link($string, 'both', TRUE);</code>
-
-
-<h2>url_title()</h2>
-<p>Takes a string as input and creates a human-friendly URL string. This is useful if, for example, you have a blog
-in which you'd like to use the title of your entries in the URL.  Example:</p>
-
-<code>$title = "What's wrong with CSS?";<br />
-<br />
-$url_title = url_title($title);<br />
-<br />
-// Produces:  Whats-wrong-with-CSS
-</code>
-
-
-<p>The second parameter determines the word delimiter.  By default dashes are used.  Options are:  <dfn>dash</dfn>, or <dfn>underscore</dfn>:</p>
-
-<code>$title = "What's wrong with CSS?";<br />
-<br />
-$url_title = url_title($title, 'underscore');<br />
-<br />
-// Produces:  Whats_wrong_with_CSS
-</code>
-
-<p>The third parameter determines whether or not lowercase characters are forced.  By default they are not.  Options are boolean <dfn>TRUE</dfn>/<dfn>FALSE</dfn>:</p>
-
-<code>$title = "What's wrong with CSS?";<br />
-<br />
-$url_title = url_title($title, 'underscore', TRUE);<br />
-<br />
-// Produces:  whats_wrong_with_css
-</code>
-
-<h3>prep_url()</h3>
-<p>This function will add <kbd>http://</kbd> in the event that a scheme is missing from a URL.  Pass the URL string to the function like this:</p>
-<code>
-$url = "example.com";<br /><br />
-$url = prep_url($url);</code>
-
-
-
-
-<h2>redirect()</h2>
-
-<p>Does a "header redirect" to the URI specified. If you specify the full site URL that link will be build, but for local links simply providing the URI segments
-to the controller you want to direct to will create the link. The function will build the URL based on your config file values.</p>
-
-<p>The optional second parameter allows you to choose between the "location"
-method (default) or the "refresh" method.  Location is faster, but on Windows servers it can sometimes be a problem.  The optional third parameter allows you to send a specific HTTP Response Code - this could be used for example to create 301 redirects for search engine purposes. The default Response Code is 302. The third parameter is <em>only</em> available with 'location' redirects, and not 'refresh'. Examples:</p>
-
-<code>if ($logged_in == FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;redirect('/login/form/', 'refresh');<br />
-}<br />
-<br />
-// with 301 redirect<br />
-redirect('/article/13', 'location', 301);</code>
-
-<p class="important"><strong>Note:</strong> In order for this function to work it must be used before anything is outputted
-to the browser since it utilizes server headers.<br />
-<strong>Note:</strong> For  very fine grained control over headers, you should use the <a href="../libraries/output.html">Output  Library</a>'s set_header() function.</p>

-<h2>Welcome to CodeIgniter</h2>
-
-<p>CodeIgniter is an Application Development Framework - a toolkit - for people who build web sites using PHP.
-Its goal is to enable you to develop projects much faster than you could if you were writing code
-from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and
-logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by
-minimizing the amount of code needed for a given task.</p>
-
-
-<h2>Who is CodeIgniter For?</h2>
-
-<p>CodeIgniter is right for you if:</p>
-
-<ul>
-<li>You want a framework with a small footprint.</li>
-<li>You need exceptional performance.</li>
-<li>You need broad compatibility with standard hosting accounts that run a variety of PHP versions and configurations.</li>
-<li>You want a framework that requires nearly zero configuration.</li>
-<li>You want a framework that does not require you to use the command line.</li>
-<li>You want a framework that does not require you to adhere to restrictive coding rules.</li>
-<li>You are not interested in large-scale monolithic libraries like PEAR.</li>
-<li>You do not want to be forced to learn a templating language (although a template parser is optionally available if you desire one).</li>
-<li>You eschew complexity, favoring simple solutions.</li>
-<li>You need clear, thorough documentation.</li>
-</ul>

-<h1>Installation Instructions</h1>
-
-<p>CodeIgniter is installed in four steps:</p>
-
-<ol>
-<li>Unzip the package.</li>
-<li>Upload the CodeIgniter folders and files to your server.  Normally the index.php file will be at your root.</li>
-<li>Open the <dfn>application/config/config.php</dfn> file with a text editor and set your base URL.  If you intend to use encryption or sessions, set your encryption key.</li>
-<li>If you intend to use a database, open the <dfn>application/config/database.php</dfn> file with a text editor and set your database settings.</li>
-</ol>
-
-<p>If you wish to increase security by hiding the location of your CodeIgniter files you can rename the <dfn>system</dfn> and <dfn>application</dfn> folders
-to something more private.  If you do rename them, you must open your main <kbd>index.php</kbd> file and set the <samp>$system_path</samp> and <samp>$application_folder</samp>
-variables at the top of the file with the new name you've chosen.</p>
-
-<p>For the best security, both the <dfn>system</dfn> and any <dfn>application</dfn> folders should be placed above web root so that they are not directly accessible via a browser.  By default, .htaccess files are included in each folder to help prevent direct access, but it is best to remove them from public access entirely in case the web server configuration changes or doesn't abide by the .htaccess.</p>
-
-<p>If you would like to keep your views public it is also possible to move the <dfn>views</dfn> folder out of your application folder.</p>
-
-<p>After moving them, open your main <kdb>index.php</kbd> file and set the <samp>$system_path</samp>, <samp>$application_folder</samp> and <samp>$view_folder</samp> variables, preferably with a full path, e.g. '<dfn>/www/MyUser/system</dfn>'.</p>
-
-<p>
-    One additional measure to take in production environments is to disable
-    PHP error reporting and any other development-only functionality. In CodeIgniter,
-    this can be done by setting the <kbd>ENVIRONMENT</kbd> constant, which is
-    more fully described on the <a href="../general/security.html">security page</a>.
-</p>
-
-<p>That's it!</p>
-
-<p>If you're new to CodeIgniter, please read the <a href="../overview/getting_started.html">Getting Started</a> section of the User Guide to begin learning how
-to build dynamic PHP applications. Enjoy!</p>

-<h1>Troubleshooting</h1>
-
-<p>If you find that no matter what you put in your URL only your default page is loading, it might be that your server
-does not support the PATH_INFO variable needed to serve search-engine friendly URLs.
-
-As a first step, open your <dfn>application/config/config.php</dfn> file and look for the <kbd>URI Protocol</kbd>
-information. It will recommend that you try a couple alternate settings.  If it still doesn't work after you've tried this you'll need
-to force CodeIgniter to add a question mark to your URLs.  To do this open your <kbd>application/config/config.php</kbd> file and change this:</p>
-
-<code>$config['index_page'] = "index.php";</code>
-
-<p>To this:</p>
-
-<code>$config['index_page'] = "index.php?";</code>

-<h1>Upgrading from 1.2 to 1.3</h1>
-
-<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.2.  If you
-have not upgraded to that version please do so first.</p>
-
-
-<p>Before performing an update you should take your site offline by replacing the index.php file
-with a static one.</p>
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace the following directories in your "system" folder with the new versions:</p>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-<ul>
-<li>application/<strong>models</strong>/&nbsp;&nbsp;  (new for 1.3)</li>
-<li>codeigniter&nbsp;&nbsp;   (new for 1.3)</li>
-<li>drivers</li>
-<li>helpers</li>
-<li>init</li>
-<li>language</li>
-<li>libraries</li>
-<li>plugins</li>
-<li>scaffolding</li>
-</ul>
-
-
-<h2>Step 2: Update your error files</h2>
-
-<p>Version 1.3 contains two new error templates located in <dfn>application/errors</dfn>, and for naming consistency the other error templates have
-been renamed.</p>
-
-<p>If you <strong>have not</strong> customized any of the error templates simply
-replace this folder:</p>
-
-<ul>
-<li>application/errors/</li>
-</ul>
-
-<p>If you <strong>have</strong> customized your error templates, rename them as follows:</p>
-
-
-<ul>
-<li>404.php&nbsp;&nbsp; =&nbsp; error_404.php</li>
-<li>error.php&nbsp;&nbsp; =&nbsp; error_general.php</li>
-<li>error_db.php&nbsp;&nbsp; (new)</li>
-<li>error_php.php&nbsp;&nbsp; (new)</li>
-</ul>
-
-
-<h2>Step 3: Update your index.php file</h2>
-
-<p>Please open your main <dfn>index.php</dfn> file (located at your root).  At the very bottom of the file, change this:</p>
-
-<code>require_once BASEPATH.'libraries/Front_controller'.EXT;</code>
-
-<p>To this:</p>
-
-<code>require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;</code>
-
-
-<h2>Step 4: Update your config.php file</h2>
-
-<p>Open your <dfn>application/config/config.php</dfn> file and add these new items:</p>
-
-<pre>
-/*
-|------------------------------------------------
-| URL suffix
-|------------------------------------------------
-|
-| This option allows you to add a suffix to all URLs.
-| For example, if a URL is this:
-|
-| example.com/index.php/products/view/shoes
-|
-| You can optionally add a suffix, like ".html",
-| making the page appear to be of a certain type:
-|
-| example.com/index.php/products/view/shoes.html
-|
-*/
-$config['url_suffix'] = "";
-
-
-/*
-|------------------------------------------------
-| Enable Query Strings
-|------------------------------------------------
-|
-| By default CodeIgniter uses search-engine and
-| human-friendly segment based URLs:
-|
-| example.com/who/what/where/
-|
-| You can optionally enable standard query string
-| based URLs:
-|
-| example.com?who=me&what=something&where=here
-|
-| Options are: TRUE or FALSE (boolean)
-|
-| The two other items let you set the query string "words"
-| that will invoke your controllers and functions:
-| example.com/index.php?c=controller&m=function
-|
-*/
-$config['enable_query_strings'] = FALSE;
-$config['controller_trigger'] = 'c';
-$config['function_trigger'] = 'm';
-</pre>
-
-
-<h2>Step 5: Update your database.php file</h2>
-
-<p>Open your <dfn>application/config/database.php</dfn> file and add these new items:</p>
-
-<pre>
-$db['default']['dbprefix'] = "";
-$db['default']['active_r'] = TRUE;
-</pre>
-
-
-<h2>Step 6: Update your user guide</h2>
-
-<p>Please also replace your local copy of the user guide with the new version.</p>

-<h1>Upgrading from 1.4.0 to 1.4.1</h1>
-
-<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.4.0.  If you
-have not upgraded to that version please do so first.</p>
-
-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
-
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace the following directories in your "system" folder with the new versions:</p>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-<ul>
-<li>codeigniter</li>
-<li>drivers</li>
-<li>helpers</li>
-<li>libraries</li>
-</ul>
-
-
-<h2>Step 2: Update your config.php file</h2>
-
-<p>Open your <dfn>application/config/config.php</dfn> file and add this new item:</p>
-
-<pre>
-
-/*
-|--------------------------------------------------------------------------
-| Output Compression
-|--------------------------------------------------------------------------
-|
-| Enables Gzip output compression for faster page loads.  When enabled,
-| the output class will test whether your server supports Gzip.
-| Even if it does, however, not all browsers support compression
-| so enable only if you are reasonably sure your visitors can handle it.
-|
-| VERY IMPORTANT:  If you are getting a blank page when compression is enabled it
-| means you are prematurely outputting something to your browser. It could
-| even be a line of whitespace at the end of one of your scripts.  For
-| compression to work, nothing can be sent before the output buffer is called
-| by the output class.  Do not "echo" any values with compression enabled.
-|
-*/
-$config['compress_output'] = FALSE;
-
-</pre>
-
-
-
-<h2>Step 3: Rename an Autoload Item</h2>
-
-<p>Open the following file: <dfn>application/config/autoload.php</dfn></p>
-
-<p>Find this array item:</p>
-
-<code>$autoload['core'] = array();</code>
-
-<p>And rename it to this:</p>
-
-<code>$autoload['libraries'] = array();</code>
-
-<p>This change was made to improve clarity since some users were not sure that their own libraries could be auto-loaded.</p>
-
-
-
-
-
-
-<h2>Step 4: Update your user guide</h2>
-
-<p>Please also replace your local copy of the user guide with the new version.</p>

-
-<pre>

-</pre>
-
-
-
-<h2>Step 3: Update your config.php file</h2>

-<h2>Step 4: Update your main index.php file</h2>
-
-<p>If you are running a stock <dfn>index.php</dfn> file simply replace your version with the new one.</p>
-
-<p>If your <dfn>index.php</dfn> file has internal modifications, please add your modifications to the new file and use it.</p>

-<h2>Step 5: Update your user guide</h2>

-<h1>Upgrading from 1.6.3 to 1.7.0</h1>
-
-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
-
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace these files and directories in your "system" folder with the new versions:</p>
-
-<ul>
-
-<li><dfn>system/codeigniter</dfn></li>
-<li><dfn>system/database</dfn></li>
-<li><dfn>system/helpers</dfn></li>
-<li><dfn>system/language</dfn></li>
-<li><dfn>system/libraries</dfn></li>
-</ul>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-
-<h2>Step 2: Update your Session Table</h2>
-
-<p>If you are using the Session class in your application, AND if you are storing session data to a database, you must add a new column named <dfn>user_data</dfn> to your session table.
-Here is an example of what this column might look like for MySQL:</p>
-
-<code>user_data text NOT NULL</code>
-
-<p>To add this column you will run a query similar to this:</p>
-
-<code>ALTER TABLE `ci_sessions` ADD `user_data` text NOT NULL</code>
-
-<p>You'll find more information regarding the new Session functionality in the  <a href="../libraries/sessions.html">Session class</a> page.</p>
-
-
-<h2>Step 3: Update your Validation Syntax</h2>
-
-<p>This is an <strong>optional</strong>, but recommended step, for people currently using the Validation class.  CI 1.7 introduces a new  <a href="../libraries/form_validation.html">Form Validation class</a>, which
-deprecates the old Validation library.  We have left the old one in place so that existing applications that use it will not break, but you are encouraged to
-migrate to the new version as soon as possible.  Please read the user guide carefully as the new library works a little differently, and has several new features.</p>
-
-
-
-<h2>Step 4: Update your user guide</h2>
-<p>Please replace your local copy of the user guide with the new version, including the image files.</p>

-<h1>Upgrading from 1.7.2 to 2.0.0</h1>
-
-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
-
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace all files and directories in your "system" folder <strong>except</strong> your <kbd>application</kbd> folder.</p>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-<h2>Step 2: Adjust get_dir_file_info() where necessary</h2>
-
-<p>Version 2.0.0 brings a non-backwards compatible change to <kbd>get_dir_file_info()</kbd> in the <a href="../helpers/file_helper.html">File Helper</a>.  Non-backwards compatible changes are extremely rare
-	in CodeIgniter, but this one we feel was warranted due to how easy it was to create serious server performance issues.  If you <em>need</em>
-	recursiveness where you are using this helper function, change such instances, setting the second parameter, <kbd>$top_level_only</kbd> to FALSE:</p>
-
-<code>get_dir_file_info('/path/to/directory', <kbd>FALSE</kbd>);</code>
-
-</p>
-
-<h2>Step 3: Convert your Plugins to Helpers</h2>
-
-<p>2.0.0 gets rid of the "Plugin" system as their functionality was identical to Helpers, but non-extensible.  You will need to rename your plugin files from <var>filename_pi.php</var> to <var>filename_helper.php</var>, move them to your <kbd>helpers</kbd> folder, and change all instances of:
-
-	<code>$this->load->plugin('foo');</code>
-
-to
-
-	<code>$this->load->helper('foo');</code>
-
-</p>
-
-<h2>Step 4: Update stored encrypted data</h2>
-
-<p class="important"><strong>Note:</strong> If your application does not use the Encryption library, does not store Encrypted data permanently, or is on an environment that does not support Mcrypt, you may skip this step.</p>
-
-<p>The Encryption library has had a number of improvements, some for encryption strength and some for performance, that has an unavoidable consequence of
-	making it no longer possible to decode encrypted data produced by the original version of this library.  To help with the transition, a new method has
-	been added, <kbd>encode_from_legacy()</kbd> that will decode the data with the original algorithm and return a re-encoded string using the improved methods.
-	This will enable you to easily replace stale encrypted data with fresh in your applications, either on the fly or en masse.</p>
-
-<p>Please read <a href="../libraries/encryption.html#legacy">how to use this method</a> in the Encryption library documentation.</p>
-
-<h2>Step 5: Remove loading calls for the compatibility helper.</h2>
-<p>The compatibility helper has been removed from the CodeIgniter core. All methods in it should be natively available in supported PHP versions.</p>
-
-<h2>Step 6: Update Class extension</h2>
-<p>All core classes are now prefixed with <kbd>CI_</kbd>.  Update Models and Controllers to extend CI_Model and CI_Controller, respectively.</p> 
-
-<h2>Step 7: Update Parent Constructor calls</h2>
-<p>All native CodeIgniter classes now use the PHP 5 <kbd>__construct()</kbd> convention. Please update extended libraries to call <kbd>parent::__construct()</kbd>.</p>
-
-<h2>Step 8: Update your user guide</h2>
-<p>Please replace your local copy of the user guide with the new version, including the image files.</p>

-<h1>Upgrading from 2.0.0 to 2.0.1</h1>
-
-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace all files and directories in your "system" folder and replace your index.php file. If any modifications were made to your index.php they will need to be made fresh in this new one.</p>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-
-<h2>Step 2: Replace config/mimes.php</h2>
-
-<p>This config file has been updated to contain more mime types, please copy it to <kbd>application/config/mimes.php</kbd>.</p>
-
-
-<h2>Step 3: Check for forms posting to default controller</h2>
-
-<p>
-	The default behavior for <kbd>form_open()</kbd> when called with no parameters used to be to post to the default controller, but it will now just leave an empty action="" meaning the form will submit to the current URL.
-	If submitting to the default controller was the expected behavior it will need to be changed from:
-</p>
-
-<code>echo form_open(); //&lt;form action="" method="post" accept-charset="utf-8"></code>
-
-<p>to use either a / or <kbd>base_url()</kbd>:</p>
-
-<code>echo form_open('/'); //&lt;form action="http://example.com/index.php/" method="post" accept-charset="utf-8"><br />
-echo form_open(base_url()); //&lt;form action="http://example.com/" method="post" accept-charset="utf-8"></code>

-
-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace all files and directories in your "system" folder and replace your index.php file. If any modifications were made to your index.php they will need to be made fresh in this new one.</p>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-	
-<h2>Step 2: Update your main index.php file</h2>
-
-<p>If you are running a stock <dfn>index.php</dfn> file simply replace your version with the new one.</p>
-
-<p>If your <dfn>index.php</dfn> file has internal modifications, please add your modifications to the new file and use it.</p>
-
-<h2>Step 3: Replace config/user_agents.php</h2>
-
-<p>This config file has been updated to contain more user agent types, please copy it to <kbd>application/config/user_agents.php</kbd>.</p>
-
-<h2>Step 4: Change references of the EXT constant to ".php"</h2>
-<p class="important"><strong>Note:</strong> The EXT Constant has been marked as deprecated, but has not been removed from the application.  You are encouraged to make the changes sooner rather than later.</p>
-
-<h2>Step 5: Remove APPPATH.'third_party' from autoload.php</h2>
-
-<p>Open application/config/autoload.php, and look for the following:</p>
-
-<code>$autoload['packages'] = array(APPPATH.'third_party');</code>
-
-<p>If you have not chosen to load any additional packages, that line can be changed to:</p>
-<code>$autoload['packages'] = array();</code>
-
-<p>Which should provide for nominal performance gains if not autoloading packages.</p>
-
-<h2>Update Sessions Database Tables</h2>
-
-<p>If you are using database sessions with the CI Session Library, please update your <samp>ci_sessions</samp> database table as follows:</p>
-
-<code>
-	CREATE INDEX last_activity_idx ON ci_sessions(last_activity);
-	ALTER TABLE ci_sessions MODIFY user_agent VARCHAR(120);

-<h1>Upgrading From Beta 1.0 to Beta 1.1</h1>
-
-<p>To upgrade to Beta 1.1 please perform the following steps:</p>
-
-<h2>Step 1: Replace your index file</h2>
-
-<p>Replace your main <kbd>index.php</kbd> file with the new index.php file. Note:  If you have renamed your "system" folder you will need to edit this info in the new file.</p>
-
-<h2>Step 2: Relocate your config folder</h2>
-
-<p>This version of CodeIgniter now permits multiple sets of "applications" to all share a common set of backend files. In order to enable
-each application to have its own configuration values, the <kbd>config</kbd> directory must now reside
-inside of your <dfn>application</dfn> folder, so please move it there.</p>
-
-
-<h2>Step 3: Replace directories</h2>
-
-<p>Replace the following directories with the new versions:</p>
-
-<ul>
-<li>drivers</li>
-<li>helpers</li>
-<li>init</li>
-<li>libraries</li>
-<li>scaffolding</li>
-</ul>
-
-
-<h2>Step 4: Add the calendar language file</h2>
-
-<p>There is a new language file corresponding to the new calendaring class which must be added to your language folder. Add
-the following item to your version: <dfn>language/english/calendar_lang.php</dfn></p>
-
-
-<h2>Step 5: Edit your config file</h2>
-
-<p>The original <kbd>application/config/config.php</kbd> file has a typo in it  Open the file and look for the items related to cookies:</p>
-
-<code>$conf['cookie_prefix']	= "";<br />
-$conf['cookie_domain']	= "";<br />
-$conf['cookie_path']	= "/";</code>
-
-<p>Change the array name from <kbd>$conf</kbd> to <kbd>$config</kbd>, like this:</p>
-
-<code>$config['cookie_prefix']	= "";<br />
-$config['cookie_domain']	= "";<br />
-$config['cookie_path']	= "/";</code>
-
-<p>Lastly, add the following new item to the config file (and edit the option if needed):</p>
-
-<code><br />
-/*<br />
-|------------------------------------------------<br />
-| URI PROTOCOL<br />
-|------------------------------------------------<br />
-|<br />
-| This item determines which server global <br />
-| should be used to retrieve the URI string.  The <br />
-| default setting of "auto" works for most servers.<br />
-| If your links do not seem to work, try one of <br />
-| the other delicious flavors:<br />
-| <br />
-| 'auto'			Default - auto detects<br />
-| 'path_info'		Uses the PATH_INFO <br />
-| 'query_string'	Uses the QUERY_STRING<br />
-*/<br />
-<br />
-$config['uri_protocol']	= "auto";</code>

-<h1>Benchmarking Class</h1>
-
-<p>CodeIgniter has a Benchmarking class that is always active, enabling the time difference between any
-two marked points to be calculated.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-
-<p>In addition, the benchmark is always started the moment the framework is
-invoked, and ended by the output class right before sending the final view to the browser, enabling a very accurate
-timing of the entire system execution to be shown.</p>
-
-
-<h3>Table of Contents</h3>

-<li><a href="#using">Using the Benchmark Class</a></li>
-<li><a href="#profiler">Profiling Your Benchmark Points</a></li>
-<li><a href="#execution">Displaying Total Execution Time</a></li>
-<li><a href="#memory">Displaying Memory Consumption</a></li>
-</ul>
-
-
-
-<a name="using"></a>
-<h2>Using the Benchmark Class</h2>
-
-<p>The Benchmark class can be used within your <a href="../general/controllers.html">controllers</a>,  <a href="../general/views.html">views</a>, or your  <a href="../general/models.html">models</a>.  The process for usage is this:</p>
-
-<ol>
-<li>Mark a start point</li>
-<li>Mark an end point</li>
-<li>Run the "elapsed time" function to view the results</li>
-</ol>
-
-<p>Here's an example using real code:</p>
-
-<code>$this->benchmark->mark('code_start');<br />
-<br />
-// Some code happens here<br />
-<br />
-$this->benchmark->mark('code_end');<br />
-<br />
-echo $this->benchmark->elapsed_time('code_start', 'code_end');</code>
-
-<p class="important"><strong>Note:</strong> The words "code_start" and "code_end" are arbitrary.  They are simply words used to set two markers.  You can
-use any words you want, and you can set multiple sets of markers. Consider this example:</p>
-
-<code>$this->benchmark->mark('dog');<br />
-<br />
-// Some code happens here<br />
-<br />
-$this->benchmark->mark('cat');<br />
-<br />
-// More code happens here<br />
-<br />
-$this->benchmark->mark('bird');<br />
-<br />
-echo $this->benchmark->elapsed_time('dog', 'cat');<br />
-echo $this->benchmark->elapsed_time('cat', 'bird');<br />
-echo $this->benchmark->elapsed_time('dog', 'bird');</code>
-
-
-<a name="profiler"></a>
-<h2>Profiling Your Benchmark Points</h2>
-
-<p>If you want your benchmark data to be available to the
-<a href="../general/profiling.html">Profiler</a> all of your marked points must be set up in pairs, and
-each mark point name must end with <kbd>_start</kbd> and <kbd>_end</kbd>.
-Each pair of points must otherwise be named identically. Example:</p>
-
-<code>
-$this->benchmark->mark('my_mark<kbd>_start</kbd>');<br />
-<br />
-// Some code happens here...<br />
-<br />
-$this->benchmark->mark('my_mark<kbd>_end</kbd>');
-<br /><br />
-
-$this->benchmark->mark('another_mark<kbd>_start</kbd>');<br />
-<br />
-// Some more code happens here...<br />
-<br />
-$this->benchmark->mark('another_mark<kbd>_end</kbd>');
-</code>
-
-<p>Please read the <a href="../general/profiling.html">Profiler page</a> for more information.</p>
-
-
-<a name="execution"></a>
-<h2>Displaying Total Execution Time</h2>
-
-<p>If you would like to display the total elapsed time from the moment CodeIgniter starts to the moment the final output
-is sent to the browser, simply place this in one of your view templates:</p>
-
-<code>&lt;?php echo $this->benchmark->elapsed_time();?&gt;</code>
-
-<p>You'll notice that it's the same function used in the examples above to calculate the time between two point, except you are
-<strong>not</strong> using any parameters.  When the parameters are absent, CodeIgniter does not stop the benchmark until right before the final
-output is sent to the browser.  It doesn't matter where you use the function call, the timer will continue to run until the very end.</p>
-
-<p>An alternate way to show your elapsed time in your view files is to use this pseudo-variable, if you prefer not to use the pure PHP:</p>
-<code>{elapsed_time}</code>
-
-<p class="important"><strong>Note:</strong> If you want to benchmark anything within your controller
-functions you must set your own start/end points.</p>
-
-<a name="memory"></a>
-<h2>Displaying Memory Consumption</h2>
-
-<p>If your PHP installation is configured with --enable-memory-limit, you can display the amount of memory consumed by the entire
-system using the following code in one of your view file:</p>
-
-<code>&lt;?php echo $this->benchmark->memory_usage();?&gt;</code>
-<p>Note: This function can only be used in your view files. The consumption will reflect the total memory used by the entire app.</p>
-
-<p>An alternate way to show your memory usage in your view files is to use this pseudo-variable, if you prefer not to use the pure PHP:</p>
-<code>{memory_usage}</code>

-
-<code>

-
-<h1 id="function_reference">Function Reference</h1>
-
-<h2>is_supported(<var>driver</var>['string'])</h2>
-
-<p>This function is automatically called when accessing drivers via <samp>$this->cache->get()</samp>.  However, if the individual drivers are used, make sure to call this function to ensure the driver is supported in the hosting environment.</p>
-
-<code>

-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}
-</code>
-
-<h2>get(<var>id</var>['string'])</h2>
-
-<p>This function will attempt to fetch an item from the cache store.  If the item does not exist, the function will return <samp>FALSE</samp>.</p>
-<code>$foo = $this->cache->get('my_cached_item');</code>
-
-<h2>save(<var>id</var>['string'], <var>data</var>['mixed'], <var>ttl</var>['int'])</h2>
-
-<p>This function will save an item to the cache store.  If saving fails, the function will return <samp>FALSE</samp>.</p>
-<p>The optional third parameter (Time To Live) defaults to 60 seconds.</p>
-<code>$this->cache->save('cache_item_id', 'data_to_cache');</code>
-
-<h2>delete(<var>id</var>['string'])</h2>
-
-<p>This function will delete a specific item from the cache store.  If item deletion fails, the function will return <samp>FALSE</samp>.</p>

-
-<p>Unlike caching from the Output Class, the driver file-based caching allows for pieces of view files to be cached.  Use this with care, and make sure to benchmark your application, as a point can come where disk I/O will negate positive gains by caching.</p>
-
-<p>All of the functions listed above can be accessed without passing a specific adapter to the driver loader as follows:</p>

-<h1>Calendaring Class</h1>
-
-<p>The Calendar class enables you to dynamically create calendars. Your calendars can be formatted through the use of a calendar
-template, allowing 100% control over every aspect of its design. In addition, you can pass data to your calendar cells.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Calendar class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('calendar');</code>
-<p>Once loaded, the Calendar object will be available using: <dfn>$this->calendar</dfn></p>
-
-
-<h2>Displaying a Calendar</h2>
-
-<p>Here is a very simple example showing how you can display a calendar:</p>
-
-<code>$this->load->library('calendar');<br />
-<br />
-echo $this->calendar->generate();</code>
-
-<p>The above code will generate a calendar for the current month/year based on your server time.
-To show a calendar for a specific month and year you will pass this information to the calendar generating function:</p>
-
-<code>$this->load->library('calendar');<br />
-<br />
-echo $this->calendar->generate(<kbd>2006</kbd>, <kbd>6</kbd>);</code>
-
-<p>The above code will generate a calendar showing the month of June in 2006.  The first parameter specifies the year, the second parameter specifies the month.</p>
-
-<h2>Passing Data to your Calendar Cells</h2>
-
-<p>To add data to your calendar cells involves creating an associative array in which the keys correspond to the days
-you wish to populate and the array value contains the data.  The array is passed to the third parameter of the calendar
-generating function.  Consider this example:</p>
-
-<code>$this->load->library('calendar');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3&nbsp; => 'http://example.com/news/article/2006/03/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7&nbsp; => 'http://example.com/news/article/2006/07/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13 => 'http://example.com/news/article/2006/13/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;26 => 'http://example.com/news/article/2006/26/'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo $this->calendar->generate(<kbd>2006</kbd>, <kbd>6</kbd>, <var>$data</var>);</code>
-
-<p>Using the above example, day numbers 3, 7, 13, and 26 will become links pointing to the URLs you've provided.</p>
-
-<p class="important"><strong>Note:</strong> By default it is assumed that your array will contain links.
-In the section that explains the calendar template below you'll see how you can customize
-how data passed to your cells is handled so you can pass different types of information.</p>
-
-
-<h2>Setting Display Preferences</h2>
-
-<p>There are seven preferences you can set to control various aspects of the calendar.  Preferences are set by passing an
-array of preferences in the second parameter of the loading function. Here is an example:</p>
-
-
-<code>
-$prefs = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'start_day'&nbsp;&nbsp;&nbsp; => 'saturday',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'month_type'&nbsp;&nbsp; => 'long',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'day_type'&nbsp;&nbsp;&nbsp;&nbsp; => 'short'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->load->library('calendar', $prefs);<br />
-<br />
-echo $this->calendar->generate();</code>
-
-<p>The above code would start the calendar on saturday, use the "long" month heading, and the "short" day names.  More information
-regarding preferences below.</p>
-
-
-
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">
-<tr>
-<th>Preference</th>
-<th>Default&nbsp;Value</th>
-<th>Options</th>
-<th>Description</th>
-</tr><tr>
-<td class="td"><strong>template</strong></td><td class="td">None</td><td class="td">None</td><td class="td">A string containing your calendar template. See the template section below.</td>
-</tr><tr>
-<td class="td"><strong>local_time</strong></td><td class="td">time()</td><td class="td">None</td><td class="td">A Unix timestamp corresponding to the current time.</td>
-</tr><tr>
-<td class="td"><strong>start_day</strong></td><td class="td">sunday</td><td class="td">Any week day (sunday, monday, tuesday, etc.)</td><td class="td">Sets the day of the week the calendar should start on.</td>
-</tr><tr>
-<td class="td"><strong>month_type</strong></td><td class="td">long</td><td class="td">long, short</td><td class="td">Determines what version of the month name to use in the header. long = January, short = Jan.</td>
-</tr><tr>
-<td class="td"><strong>day_type</strong></td><td class="td">abr</td><td class="td">long, short, abr</td><td class="td">Determines what version of the weekday names to use in the column headers. long = Sunday, short = Sun, abr = Su.</td>
-</tr><tr>
-<td class="td"><strong>show_next_prev</strong></td><td class="td">FALSE</td><td class="td">TRUE/FALSE (boolean)</td><td class="td">Determines whether to display links allowing you to toggle to next/previous months. See information on this feature below.</td>
-</tr><tr>
-<td class="td"><strong>next_prev_url</strong></td><td class="td">None</td><td class="td">A URL</td><td class="td">Sets the basepath used in the next/previous calendar links.</td>
-</tr>
-</table>
-
-
-
-<h2>Showing Next/Previous Month Links</h2>
-
-<p>To allow your calendar to dynamically increment/decrement via the next/previous links requires that you set up your calendar
-code similar to this example:</p>
-
-
-<code>$prefs = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'show_next_prev'&nbsp;&nbsp;=> TRUE,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'next_prev_url'&nbsp;&nbsp; => 'http://example.com/index.php/calendar/show/'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this-&gt;load-&gt;library('calendar', $prefs);<br />
-<br />
-echo $this->calendar->generate(<var>$this->uri->segment(3)</var>, <var>$this->uri->segment(4)</var>);</code>
-
-<p>You'll notice a few things about the above example:</p>
-
-<ul>
-<li>You must set the "show_next_prev" to TRUE.</li>
-<li>You must supply the URL to the controller containing your calendar in the "next_prev_url" preference.</li>
-<li>You must supply the "year" and "month" to the calendar generating function via the URI segments where they appear (Note:  The calendar class automatically adds the year/month to the base URL you provide.).</li>
-</ul>
-
-
-
-<h2>Creating a Calendar Template</h2>
-
-<p>By creating a calendar template you have 100% control over the design of your calendar. Each component of your
-calendar will be placed within a pair of pseudo-variables as shown here:</p>
-
-
-<code>
-$prefs['template'] = '<br /><br />
-&nbsp;&nbsp;&nbsp;<dfn>{table_open}</dfn><var>&lt;table border="0" cellpadding="0" cellspacing="0"></var><dfn>{/table_open}</dfn><br />

-<br />
-&nbsp;&nbsp;&nbsp;<dfn>{heading_row_end}</dfn><var>&lt;/tr></var><dfn>{/heading_row_end}</dfn><br />

-&nbsp;&nbsp;&nbsp;<dfn>{cal_cell_no_content_today}</dfn><var>&lt;div class="highlight"></var><kbd>{day}</kbd><var>&lt;/div></var><dfn>{/cal_cell_no_content_today}</dfn><br />
-<br />

-<h1>Shopping Cart Class</h1>
-
-<p>The Cart Class permits items to be added to a session that stays active while a user is browsing your site.
-These items can be retrieved and displayed in a standard "shopping cart" format, allowing the user to update the quantity or remove items from the cart.</p>
-
-<p>Please note that the Cart Class ONLY provides the core "cart" functionality. It does not provide shipping, credit card authorization, or other processing components.</p>
-
-
-<h2>Initializing the Shopping Cart Class</h2>
-
-<p><strong>Important:</strong> The Cart class utilizes CodeIgniter's
-<a href="sessions.html">Session Class</a>  to save the cart information to a database, so before using the Cart class you must set up a database table
-as indicated in the <a href="sessions.html">Session Documentation</a> , and set the session preferences in your <kbd>application/config/config.php</kbd> file to utilize a database.</p>
-
-<p>To initialize the Shopping Cart Class in your controller constructor, use the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('cart');</code>
-<p>Once loaded, the Cart object will be available using: <dfn>$this->cart</dfn></p>
-
-<p class="important"><strong>Note:</strong> The Cart Class will load and initialize the Session Class automatically, so unless you are using sessions elsewhere in your application, you do not need to load the Session class.</p>
-
-<h2>Adding an Item to The Cart</h2>
-
-<p>To add an item to the shopping cart, simply pass an array with the product information to the <dfn>$this->cart->insert()</dfn> function, as shown below:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'sku_123ABC',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'qty'&nbsp;&nbsp;&nbsp;&nbsp; => 1,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'price'&nbsp;&nbsp; => 39.95,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp; => 'T-Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'options' => array('Size' => 'L', 'Color' => 'Red')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-
-$this->cart->insert($data);
-
-</code>
-
-<p class="important"><strong>Important:</strong> The first four array indexes above (<dfn>id</dfn>, <dfn>qty</dfn>, <dfn>price</dfn>, and <dfn>name</dfn>) are <strong>required</strong>.
-If you omit any of them the data will not be saved to the cart. The fifth index (<dfn>options</dfn>) is optional.
-It is intended to be used in cases where your product has options associated with it. Use an array for options, as shown above.</p>
-
-<p>The five reserved indexes are:</p>
-
-<ul>
-<li><strong>id</strong> - Each product in your store must have a unique identifier. Typically this will be an "sku" or other such identifier.</li>
-<li><strong>qty</strong> - The quantity being purchased.
-<li><strong>price</strong> - The price of the item.
-<li><strong>name</strong> - The name of the item.
-<li><strong>options</strong> - Any additional attributes that are needed to identify the product. These must be passed via an array.
-</ul>
-
-<p>In addition to the five indexes above, there are two reserved words: <dfn>rowid</dfn> and <dfn>subtotal</dfn>.  These are used internally by the Cart class, so
-please do NOT use those words as index names when inserting data into the cart.</p>
-
-<p>Your array may contain additional data. Anything you include in your array will be stored in the session. However, it is best to standardize your data among all your products in order to make displaying the information in a table easier.</p>
-
-<p>The insert() method will return the $rowid if you successfully insert a single item.</p>
-
-
-<h2>Adding Multiple Items to The Cart</h2>
-
-<p>By using a multi-dimensional array, as shown below, it is possible to add multiple products to the cart in one action. This is useful in cases where you wish to allow people to select from among several items on the same page.</p>
-
-
-<code>
-$data = array(<br />
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />

-</code>
-
-<p><strong>What is a Row ID?</strong>&nbsp; The <kbd>row ID</kbd> is a unique identifier that is generated by the cart code when an item is added to the cart.  The reason a
-unique ID is created is so that identical products with different options can be managed by the cart.</p>
-
-<p>For example, let's say someone buys two identical t-shirts (same product ID), but in different sizes. The product ID (and other attributes) will be
-identical for both sizes because it's the same shirt. The only difference will be the size. The cart must therefore have a means of identifying this
-difference so that the two sizes of shirts can be managed independently. It does so by creating a unique "row ID" based on the product ID and any options associated with it.</p>
-
-<p>In nearly all cases, updating the cart will be something the user does via the "view cart" page, so as a developer, it is unlikely that you will ever have to concern yourself
-with the "row ID", other then making sure your "view cart" page contains this information in a hidden form field, and making sure it gets passed to the update
-function when the update form is submitted. Please examine the construction of the "view cart" page above for more information.</p>

-<h1>Config Class</h1>
-
-<p>The Config class provides a means to retrieve configuration preferences.  These preferences can
-come from the default config file (<samp>application/config/config.php</samp>) or from your own custom config files.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-
-<h2>Anatomy of a Config File</h2>
-
-<p>By default, CodeIgniter has one primary config file, located at <samp>application/config/config.php</samp>.  If you open the file using
-your text editor you'll see that config items are stored in an array called <var>$config</var>.</p>
-
-<p>You can add your own config items to
-this file, or if you prefer to keep your configuration items separate (assuming you even need config items),
-simply create your own file and save it in <dfn>config</dfn> folder.</p>
-
-<p><strong>Note:</strong> If you do create your own config files use the same format as the primary one, storing your items in
-an array called  <var>$config</var>. CodeIgniter will intelligently manage these files so there will be no conflict even though
-the array has the same name (assuming an array index is not named the same as another).</p>
-
-<h2>Loading a Config File</h2>
-
-<p><strong>Note:</strong> CodeIgniter automatically loads the primary config file (<samp>application/config/config.php</samp>),
-so you will only need to load a config file if you have created your own.</p>
-
-<p>There are two ways to load a config file:</p>
-
-<ol><li><strong>Manual Loading</strong>
-
-<p>To load one of your custom config files you will use the following function within the <a href="../general/controllers.html">controller</a> that needs it:</p>
-
-<code>$this->config->load('<var>filename</var>');</code>
-
-<p>Where <var>filename</var> is the name of your config file, without the .php file extension.</p>
-
-<p>If you need to load multiple config files normally they will be merged into one master config array.  Name collisions can occur, however, if
-you have identically named array indexes in different config files.  To avoid collisions you can set the second parameter to <kbd>TRUE</kbd>
-and each config file will be stored in an array index corresponding to the name of the config file. Example:</p>
-
-<code>
-// Stored in an array with this prototype:  $this->config['blog_settings'] = $config<br />
-$this->config->load('<var>blog_settings</var>', <kbd>TRUE</kbd>);</code>
-
-<p>Please see the section entitled <dfn>Fetching Config Items</dfn> below to learn how to retrieve config items set this way.</p>
-
-<p>The third parameter allows you to suppress errors in the event that a config file does not exist:</p>
-
-<code>$this->config->load('<var>blog_settings</var>', <dfn>FALSE</dfn>, <kbd>TRUE</kbd>);</code>
-
-</li>
-<li><strong>Auto-loading</strong>
-
-<p>If you find that you need a particular config file globally, you can have it loaded automatically by the system.  To do this,
-open the <strong>autoload.php</strong> file, located at <samp>application/config/autoload.php</samp>, and add your config file as
-indicated in the file.</p>
-</li>
-</ol>
-
-
-<h2>Fetching Config Items</h2>
-
-<p>To retrieve an item from your config file, use the following function:</p>
-
-<code>$this->config->item('<var>item name</var>');</code>
-
-<p>Where <var>item name</var> is the $config array index you want to retrieve. For example, to fetch your language choice you'll do this:</p>
-
-<code>$lang = $this->config->item('language');</code>
-
-<p>The function returns FALSE (boolean) if the item you are trying to fetch does not exist.</p>
-
-<p>If you are using the second parameter of the <kbd>$this->config->load</kbd> function in order to assign your config items to a specific index
-you can retrieve it by specifying the index name in the second parameter of the <kbd>$this->config->item()</kbd> function.  Example:</p>
-
-<code>
-// Loads a config file named blog_settings.php and assigns it to an index named "blog_settings"<br />
-$this->config->load('<var>blog_settings</var>', <kbd>TRUE</kbd>);<br /><br />
-
-// Retrieve a config item named site_name contained within the blog_settings array<br />
-$site_name = $this->config->item('<dfn>site_name</dfn>', '<var>blog_settings</var>');<br /><br />
-
-// An alternate way to specify the same item:<br />
-$blog_config = $this->config->item('<var>blog_settings</var>');<br />
-$site_name = $blog_config['site_name'];</code>
-
-<h2>Setting a Config Item</h2>
-
-<p>If you would like to dynamically set a config item or change an existing one, you can do so using:</p>
-
-<code>$this->config->set_item('<var>item_name</var>', '<var>item_value</var>');</code>
-
-<p>Where <var>item_name</var> is the $config array index you want to change, and <var>item_value</var> is its value.</p>
-
-<a name="environments"></a>
-<h2>Environments</h2>
-
-<p>
-    You may load different configuration files depending on the current environment.
-    The <kbd>ENVIRONMENT</kbd> constant is defined in index.php, and is described
-    in detail in the <a href="../general/environments.html">Handling Environments</a>
-    section.
-</p>
-
-<p>
-    To create an environment-specific configuration file,
-    create or copy a configuration file in application/config/{ENVIRONMENT}/{FILENAME}.php
-</p>
-
-<p>For example, to create a production-only config.php, you would:</p>
-
-<ol>
-    <li>Create the directory application/config/production/</li>
-    <li>Copy your existing config.php into the above directory</li>
-    <li>Edit application/config/production/config.php so it contains your production settings</li>
-</ol>
-
-<p>
-    When you set the <kbd>ENVIRONMENT</kbd> constant to 'production', the settings
-    for your new production-only config.php will be loaded.
-</p>
-
-<p>You can place the following configuration files in environment-specific folders:</p>
-	
-<ul>
-<li>Default CodeIgniter configuration files</li>
-<li>Your own custom configuration files</li>
-</ul>
-
-<p><strong>Note:</strong> CodeIgniter always tries to load the configuration files for the current environment first. If the file does not exist, the global config file (i.e., the one in <samp>application/config/</samp>) is loaded. This means you are not obligated to place <strong>all</strong> of your configuration files in an environment folder &minus; only the files that change per environment.</p>
-
-<h2>Helper Functions</h2>
-
-<p>The config class has the following helper functions:</p>
-
-<h2>$this->config->site_url();</h2>
-<p>This function retrieves the URL to your site, along with the "index" value you've specified in the config file.</p>
-
-<h2>$this->config->base_url();</h2>
-<p>This function retrieves the URL to your site, plus an optional path such as to a stylesheet or image.</p>
-
-<p>The two functions above are normally accessed via the corresponding functions in the <a href="../helpers/url_helper.html">URL Helper.</a></p>    
-    
-<h2>$this->config->system_url();</h2>
-<p>This function retrieves the URL to your <dfn>system folder</dfn>.</p>

-<li>BCC Batch Mode, enabling large email lists to be broken into small BCC batches.</li>
-<li>Email Debugging tools</li>
-</ul>
-
-
-<h2>Sending Email</h2>
-
-<p>Sending email is not only simple, but you can configure it on the fly or set your preferences in a config file.</p>
-
-<p>Here is a basic example demonstrating how you might send email.  Note:  This example assumes you are sending the email from one of your
-<a href="../general/controllers.html">controllers</a>.</p>
-
-<code>$this->load->library('email');<br />
-<br />
-$this->email->from('your@example.com', 'Your Name');<br />
-$this->email->to('someone@example.com'); <br />
-$this->email->cc('another@another-example.com'); <br />
-$this->email->bcc('them@their-example.com'); <br />
-<br />
-$this->email->subject('Email Test');<br />
-$this->email->message('Testing the email class.');	<br />
-<br />
-$this->email->send();<br />
-<br />
-echo $this->email->print_debugger();</code>
-
-
-
-
-<h2>Setting Email Preferences</h2>
-
-<p>There are 17 different preferences available to tailor how your email messages are sent. You can either set them manually
-as described here, or automatically via preferences stored in your config file, described below:</p>
-
-<p>Preferences are set by passing an array of preference values to the email <dfn>initialize</dfn> function.  Here is an example of how you might set some preferences:</p>
-
-<code>$config['protocol'] = 'sendmail';<br />
-$config['mailpath'] = '/usr/sbin/sendmail';<br />
-$config['charset'] = 'iso-8859-1';<br />
-$config['wordwrap'] = TRUE;<br />
-<br />
-$this->email->initialize($config);</code>
-
-<p><strong>Note:</strong> Most of the preferences have default values that will be used if you do not set them.</p
-
-><h3>Setting Email Preferences in a Config File</h3>
-
-<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
-Simply create a new file called the <var>email.php</var>,  add the <var>$config</var>
-array in that file. Then save the file at <var>config/email.php</var> and it will be used automatically. You
-will NOT need to use the <dfn>$this->email->initialize()</dfn> function if you save your preferences in a config file.</p>
-
-
-
-
-<h2>Email Preferences</h2>
-
-<p>The following is a list of all the preferences that can be set when sending email.</p>

-<h2>Email Function Reference</h2>
-
-<h3>$this->email->from()</h3>
-<p>Sets the email address and name of the person sending the email:</p>
-<code>$this->email->from('<var>you@example.com</var>', '<var>Your Name</var>');</code>
-
-<h3>$this->email->reply_to()</h3>
-<p>Sets the reply-to address.  If the information is not provided the information in the "from" function is used. Example:</p>
-<code>$this->email->reply_to('<var>you@example.com</var>', '<var>Your Name</var>');</code>
-
-
-<h3>$this->email->to()</h3>
-<p>Sets the email address(s) of the recipient(s).  Can be a single email, a comma-delimited list or an array:</p>
-
-<code>$this->email->to('<var>someone@example.com</var>');</code>
-<code>$this->email->to('<var>one@example.com</var>, <var>two@example.com</var>, <var>three@example.com</var>');</code>
-
-<code>$list = array('<var>one@example.com</var>', '<var>two@example.com</var>', '<var>three@example.com</var>');<br />
-<br />
-$this->email->to(<var>$list</var>);</code>
-
-<h3>$this->email->cc()</h3>
-<p>Sets the CC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.</p>
-
-<h3>$this->email->bcc()</h3>
-<p>Sets the BCC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.</p>
-
-
-<h3>$this->email->subject()</h3>
-<p>Sets the email subject:</p>
-<code>$this->email->subject('<var>This is my subject</var>');</code>
-
-<h3>$this->email->message()</h3>
-<p>Sets the email message body:</p>
-<code>$this->email->message('<var>This is my message</var>');</code>
-
-<h3>$this->email->set_alt_message()</h3>
-<p>Sets the alternative email message body:</p>
-<code>$this->email->set_alt_message('<var>This is the alternative message</var>');</code>
-
-<p>This is an optional message string which can be used if you send HTML formatted email.  It lets you specify an alternative
-message with no HTML formatting which is added to the header string for people who do not accept HTML email.
-If you do not set your own message CodeIgniter will extract the message from your HTML email and strip the tags.</p>
-
-
-
-<h3>$this->email->clear()</h3>
-<p>Initializes all the email variables to an empty state.  This function is intended for use if you run the email sending function
-in a loop, permitting the data to be reset between cycles.</p>
-<code>foreach ($list as $name => $address)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->clear();<br /><br />
-
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->to($address);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->from('your@example.com');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->subject('Here is your info '.$name);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->message('Hi '.$name.' Here is the info you requested.');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->send();<br />
-}</code>
-
-<p>If you set the parameter to TRUE any attachments will be cleared as well:</p>
-
-<code>$this->email->clear(TRUE);</code>
-
-
-<h3>$this->email->send()</h3>
-<p>The Email sending function. Returns boolean TRUE or FALSE based on success or failure, enabling it to be used
-conditionally:</p>
-
-<code>if ( ! $this->email->send())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;// Generate error<br />
-}</code>
-
-
-<h3>$this->email->attach()</h3>
-<p>Enables you to send an attachment. Put the file path/name in the first parameter. Note: Use a file path, not a URL.
-For multiple attachments use the function multiple times. For example:</p>
-
-<code>$this->email->attach('/path/to/photo1.jpg');<br />
-$this->email->attach('/path/to/photo2.jpg');<br />
-$this->email->attach('/path/to/photo3.jpg');<br />
-<br />
-$this->email->send();</code>
-
-
-<h3>$this->email->print_debugger()</h3>
-<p>Returns a string containing any server messages, the email headers, and the email messsage.  Useful for debugging.</p>
-
-
-<h2>Overriding Word Wrapping</h2>
-
-<p>If you have word wrapping enabled (recommended to comply with RFC 822) and you have a very long link in your email it can
-get wrapped too, causing it to become un-clickable by the person receiving it.  CodeIgniter lets you manually override
-word wrapping within part of your message like this:</p>
-
-<code>The text of your email that<br />
-gets wrapped normally.<br />
-<br />
-<var>{unwrap}</var>http://example.com/a_long_link_that_should_not_be_wrapped.html<var>{/unwrap}</var><br />
-<br />
-More text that will be<br />
-wrapped normally.</code>
-
-<p>Place the item you do not want word-wrapped between: <var>{unwrap}</var> <var>{/unwrap}</var></p>

-<h1>Encryption Class</h1>
-
-<p>The Encryption Class provides two-way data encryption.  It uses a scheme that either compiles
-the message using a randomly hashed bitwise XOR encoding scheme, or is encrypted using
-the Mcrypt library.  If Mcrypt is not available on your server the encoded message will
-still provide a reasonable degree of security for encrypted sessions or other such "light" purposes.
-If Mcrypt is available, you'll be provided with a high degree of security appropriate for storage.</p>
-
-
-<h2>Setting your Key</h2>
-
-<p>A <em>key</em> is a piece of information that controls the cryptographic process and permits an encrypted string to be decoded.
-In fact, the key you chose will provide the <strong>only</strong> means to decode data that was encrypted with that key,
-so not only must you choose the key carefully, you must never change it if you intend use it for persistent data.</p>
-
-<p>It goes without saying that you should guard your key carefully.
-Should someone gain access to your key, the data will be easily decoded.  If your server is not totally under your control
-it's impossible to ensure key security so you may want to think carefully before using it for anything
-that requires high security, like storing credit card numbers.</p>
-
-<p>To take maximum advantage of the encryption algorithm, your key should be 32 characters in length (128 bits).
-The key should be as random a string as you can concoct, with numbers and uppercase and lowercase letters.
-Your key should <strong>not</strong> be a simple text string. In order to be cryptographically secure it
-needs to be as random as possible.</p>
-
-<p>Your key can be either stored in your <dfn>application/config/config.php</dfn>, or you can design your own
-storage mechanism and pass the key dynamically when encoding/decoding.</p>
-
-<p>To save your key to your <dfn>application/config/config.php</dfn>, open the file and set:</p>
-<code>$config['encryption_key'] = "YOUR KEY";</code>
-
-
-<h2>Message Length</h2>
-
-<p>It's important for you to know that the encoded messages the encryption function generates will be approximately 2.6 times longer than the original
-message.  For example, if you encrypt the string "my super secret data", which is 21 characters in length, you'll end up
-with an encoded string that is roughly 55 characters (we say "roughly" because the encoded string length increments in
-64 bit clusters, so it's not exactly linear).  Keep this information in mind when selecting your data storage mechanism.  Cookies,
-for example, can only hold 4K of information.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Encryption class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('encrypt');</code>
-<p>Once loaded, the Encrypt library object will be available using: <dfn>$this->encrypt</dfn></p>
-
-
-<h2>$this->encrypt->encode()</h2>
-
-<p>Performs the data encryption and returns it as a string. Example:</p>
-<code>
-$msg = 'My secret message';<br />
-<br />
-$encrypted_string = $this->encrypt->encode($msg);</code>
-
-<p>You can optionally pass your encryption key via the second parameter if you don't want to use the one in your config file:</p>
-
-<code>
-$msg = 'My secret message';<br />
-$key = 'super-secret-key';<br />
-<br />
-$encrypted_string = $this->encrypt->encode($msg, $key);</code>
-
-
-<h2>$this->encrypt->decode()</h2>
-
-<p>Decrypts an encoded string.  Example:</p>
-
-<code>
-$encrypted_string = 'APANtByIGI1BpVXZTJgcsAG8GZl8pdwwa84';<br />
-<br />
-$plaintext_string = $this->encrypt->decode($encrypted_string);</code>
-
-<p>You can optionally pass your encryption key via the second parameter if you don't want to use the one in your config file:</p>
-
-<code>
-$msg = 'My secret message';<br />
-$key = 'super-secret-key';<br />
-<br />
-$encrypted_string = $this->encrypt->decode($msg, $key);</code>
-
-
-<h2>$this->encrypt->set_cipher();</h2>
-
-<p>Permits you to set an Mcrypt cipher.  By default it uses <samp>MCRYPT_RIJNDAEL_256</samp>.  Example:</p>
-<code>$this->encrypt->set_cipher(MCRYPT_BLOWFISH);</code>
-<p>Please visit php.net for a list of  <a href="http://php.net/mcrypt">available ciphers</a>.</p>
-
-<p>If you'd like to manually test whether your server supports Mcrypt you can use:</p>
-<code>echo ( ! function_exists('mcrypt_encrypt')) ? 'Nope' : 'Yup';</code>
-
-
-<h2>$this->encrypt->set_mode();</h2>
-
-<p>Permits you to set an Mcrypt mode.  By default it uses <samp>MCRYPT_MODE_CBC</samp>.  Example:</p>
-<code>$this->encrypt->set_mode(MCRYPT_MODE_CFB);</code>
-<p>Please visit php.net for a list of  <a href="http://php.net/mcrypt">available modes</a>.</p>
-
-
-<h2>$this->encrypt->sha1();</h2>
-<p>SHA1 encoding function.  Provide a string and it will return a 160 bit one way hash.  Note:  SHA1, just like MD5 is non-decodable. Example:</p>
-<code>$hash = $this->encrypt->sha1('Some string');</code>
-
-<p>Many PHP installations have SHA1 support by default so if all you need is to encode a hash it's simpler to use the native
-function:</p>
-
-<code>$hash = sha1('Some string');</code>
-
-<p>If your server does not support SHA1 you can use the provided function.</p>
-
-<h2 id="legacy">$this->encrypt->encode_from_legacy(<kbd>$orig_data</kbd>, <kbd>$legacy_mode</kbd> = MCRYPT_MODE_ECB, <kbd>$key</kbd> = '');</h2>
-<p>Enables you to re-encode data that was originally encrypted with CodeIgniter 1.x to be compatible with the Encryption library in CodeIgniter 2.x.  It is only
-	necessary to use this method if you have encrypted data stored permanently such as in a file or database and are on a server that supports Mcrypt.  "Light" use encryption
-	such as encrypted session data or transitory encrypted flashdata require no intervention on your part.  However, existing encrypted Sessions will be
-	destroyed since data encrypted prior to 2.x will not be decoded.</p>
-
-<p class="important"><strong>Why only a method to re-encode the data instead of maintaining legacy methods for both encoding and decoding?</strong>  The algorithms in
-	the Encryption library have improved in CodeIgniter 2.x	both for performance and security, and we do not wish to encourage continued use of the older methods.
-	You can of course extend the Encryption library if you wish and replace the new methods with the old and retain seamless compatibility with CodeIgniter 1.x
-	encrypted data, but this a decision that a developer should make cautiously and deliberately, if at all.</p>
-
-<code>$new_data = $this->encrypt->encode_from_legacy(<kbd>$old_encrypted_string</kbd>);</code>
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">

-<h1>File Uploading Class</h1>
-
-<p>CodeIgniter's File Uploading Class permits files to be uploaded.  You can set various
-preferences, restricting the type and size of the files.</p>
-
-
-<h2>The Process</h2>
-
-<p>Uploading a file involves the following general process:</p>
-
-
-<ul>
-<li>An upload form is displayed, allowing a user to select a file and upload it.</li>
-<li>When the form is submitted, the file is uploaded to the destination you specify.</li>
-<li>Along the way, the file is validated to make sure it is allowed to be uploaded based on the preferences you set.</li>
-<li>Once uploaded, the user will be shown a success message.</li>
-</ul>
-
-<p>To demonstrate this process here is brief tutorial. Afterward you'll find reference information.</p>
-
-<h2>Creating the Upload Form</h2>
-
-
-
-<p>Using a text editor, create a form called <dfn>upload_form.php</dfn>.  In it, place this code and save it to your <samp>applications/views/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="23">
-&lt;html>
-&lt;head>
-&lt;title>Upload Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;?php echo $error;?>
-
-&lt;?php echo form_open_multipart('upload/do_upload');?>
-
-&lt;input type="file" name="userfile" size="20" />
-
-&lt;br />&lt;br />
-
-&lt;input type="submit" value="upload" />
-
-&lt;/form>
-
-&lt;/body>
-&lt;/html></textarea>
-
-<p>You'll notice we are using a form helper to create the opening form tag.  File uploads require a multipart form, so the helper
-creates the proper syntax for you.  You'll also notice we have an $error variable.  This is so we can show error messages in the event
-the user does something wrong.</p>
-
-
-<h2>The Success Page</h2>
-
-<p>Using a text editor, create a form called <dfn>upload_success.php</dfn>.
-In it, place this code and save it to your <samp>applications/views/</samp> folder:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="20">&lt;html>
-&lt;head>
-&lt;title>Upload Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;h3>Your file was successfully uploaded!&lt;/h3>
-
-&lt;ul>
-&lt;?php foreach ($upload_data as $item => $value):?>
-&lt;li>&lt;?php echo $item;?>: &lt;?php echo $value;?>&lt;/li>
-&lt;?php endforeach; ?>
-&lt;/ul>
-
-&lt;p>&lt;?php echo anchor('upload', 'Upload Another File!'); ?>&lt;/p>
-
-&lt;/body>
-&lt;/html></textarea>
-
-
-<h2>The Controller</h2>
-
-<p>Using a text editor, create a controller called <dfn>upload.php</dfn>.  In it, place this code and save it to your <samp>applications/controllers/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="43">&lt;?php
-
-class Upload extends CI_Controller {
-
-	function __construct()
-	{
-		parent::__construct();
-		$this->load->helper(array('form', 'url'));
-	}
-
-	function index()
-	{
-		$this->load->view('upload_form', array('error' => ' ' ));
-	}
-
-	function do_upload()
-	{
-		$config['upload_path'] = './uploads/';
-		$config['allowed_types'] = 'gif|jpg|png';
-		$config['max_size']	= '100';
-		$config['max_width']  = '1024';
-		$config['max_height']  = '768';
-
-		$this->load->library('upload', $config);
-
-		if ( ! $this->upload->do_upload())
-		{
-			$error = array('error' => $this->upload->display_errors());
-
-			$this->load->view('upload_form', $error);
-		}
-		else
-		{
-			$data = array('upload_data' => $this->upload->data());
-
-			$this->load->view('upload_success', $data);
-		}
-	}
-}
-?&gt;</textarea>
-
-
-<h2>The Upload Folder</h2>
-
-<p>You'll need a destination folder for your uploaded images.  Create a folder at the root of your CodeIgniter installation called
-<dfn>uploads</dfn> and set its file permissions to 777.</p>
-
-
-<h2>Try it!</h2>
-
-<p>To try your form, visit your site using a URL similar to this one:</p>
-
-<code>example.com/index.php/<var>upload</var>/</code>
-
-<p>You should see an upload form. Try uploading an image file (either a jpg, gif, or png). If the path in your
-controller is correct it should work.</p>
-
-
-<p>&nbsp;</p>
-
-<h1>Reference Guide</h1>
-
-
-<h2>Initializing the Upload Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Upload class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('upload');</code>
-<p>Once the Upload class is loaded, the object will be available using: <dfn>$this->upload</dfn></p>
-
-
-<h2>Setting Preferences</h2>
-
-<p>Similar to other libraries, you'll control what is allowed to be upload based on your preferences.  In the controller you
-built above you set the following preferences:</p>
-
-<code>$config['upload_path'] = './uploads/';<br />
-$config['allowed_types'] = 'gif|jpg|png';<br />
-$config['max_size']	= '100';<br />
-$config['max_width']  = '1024';<br />
-$config['max_height']  = '768';<br />
-<br />
-$this->load->library('upload', $config);<br /><br />
-
-// Alternately you can set preferences by calling the initialize function.  Useful if you auto-load the class:<br />
-$this->upload->initialize($config);</code>
-
-<p>The above preferences should be fairly self-explanatory.  Below is a table describing all available preferences.</p>
-
-
-<h2>Preferences</h2>
-
-<p>The following preferences are available.  The default value indicates what will be used if you do not specify that preference.</p>
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">
-<tr>
-<th>Preference</th>
-<th>Default&nbsp;Value</th>
-<th>Options</th>
-<th>Description</th>
-</tr>
-
-<tr>
-<td class="td"><strong>upload_path</strong></td>
-<td class="td">None</td>
-<td class="td">None</td>
-<td class="td">The path to the folder where the upload should be placed.  The folder must be writable and the path can be absolute or relative.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>allowed_types</strong></td>
-<td class="td">None</td>
-<td class="td">None</td>
-<td class="td">The mime types corresponding to the types of files you allow to be uploaded.  Usually the file extension can be used as the mime type.  Separate multiple types with a pipe.</td>
-</tr>
-
-
-<tr>
-<td class="td"><strong>file_name</strong></td>
-<td class="td">None</td>
-<td class="td">Desired file name</td>
-<td class="td">
-	<p>If set CodeIgniter will rename the uploaded file to this name.  The extension provided in the file name must also be an allowed file type.</p>
-</td>
-</tr>
-
-<tr>
-<td class="td"><strong>overwrite</strong></td>
-<td class="td">FALSE</td>
-<td class="td">TRUE/FALSE (boolean)</td>
-<td class="td">If set to true, if a file with the same name as the one you are uploading exists, it will be overwritten. If set to false, a number will be appended to the filename if another with the same name exists.</td>
-</tr>
-
-
-<tr>
-<td class="td"><strong>max_size</strong></td>
-<td class="td">0</td>
-<td class="td">None</td>
-<td class="td">The maximum size (in kilobytes) that the file can be.  Set to zero for no limit. Note:  Most PHP installations have their own limit, as specified in the php.ini file.  Usually 2 MB (or 2048 KB) by default.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>max_width</strong></td>
-<td class="td">0</td>
-<td class="td">None</td>
-<td class="td">The maximum width (in pixels) that the file can be.  Set to zero for no limit.</td>

-<td class="td">When overwrite is set to FALSE, use this to set the maximum filename increment for CodeIgniter to append to the filename.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>encrypt_name</strong></td>
-<td class="td">FALSE</td>
-<td class="td">TRUE/FALSE (boolean)</td>
-<td class="td">If set to TRUE the file name will be converted to a random encrypted string. This can be useful if you would like the file saved with a name that can not be discerned by the person uploading it.</td>

-
-<tr>
-<td class="td"><strong>remove_spaces</strong></td>
-<td class="td">TRUE</td>
-<td class="td">TRUE/FALSE (boolean)</td>
-<td class="td">If set to TRUE, any spaces in the file name will be converted to underscores. This is recommended.</td>
-</tr>
-</table>
-
-
-<h2>Setting preferences in a config file</h2>
-
-<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
-Simply create a new file called the <var>upload.php</var>,  add the <var>$config</var>
-array in that file. Then save the file in: <var>config/upload.php</var> and it will be used automatically. You
-will NOT need to use the <dfn>$this->upload->initialize</dfn> function if you save your preferences in a config file.</p>
-
-
-<h2>Function Reference</h2>
-
-<p>The following functions are available</p>
-
-
-<h2>$this->upload->do_upload()</h2>
-
-<p>Performs the upload based on the preferences you've set.  Note:  By default the upload routine expects the file to come from a form field
-called <dfn>userfile</dfn>, and the form must be a "multipart type:</p>
-
-<code>&lt;form method="post" action="some_action" enctype="multipart/form-data" /></code>
-
-<p>If you would like to set your own field name simply pass its value to the <dfn>do_upload</dfn> function:</p>
-
-<code>
-$field_name = "some_field_name";<br />
-$this->upload->do_upload($field_name)</code>
-
-
-<h2>$this->upload->display_errors()</h2>
-
-<p>Retrieves any error messages if the <dfn>do_upload()</dfn> function returned false.  The function does not echo automatically, it
-returns the data so you can assign it however you need.</p>
-
-<h3>Formatting Errors</h3>
-<p>By default the above function wraps any errors within &lt;p> tags.  You can set your own delimiters like this:</p>
-
-<code>$this->upload->display_errors('<var>&lt;p></var>', '<var>&lt;/p></var>');</code>
-
-<h2>$this->upload->data()</h2>
-
-<p>This is a helper function that returns an array containing all of the data related to the file you uploaded.
-Here is the array prototype:</p>
-
-<code>Array<br />
-(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_name]&nbsp;&nbsp;&nbsp;&nbsp;=> mypic.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_type]&nbsp;&nbsp;&nbsp;&nbsp;=> image/jpeg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_path]&nbsp;&nbsp;&nbsp;&nbsp;=> /path/to/your/upload/<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[full_path]&nbsp;&nbsp;&nbsp;&nbsp;=> /path/to/your/upload/jpg.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[raw_name]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> mypic<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[orig_name]&nbsp;&nbsp;&nbsp;&nbsp;=> mypic.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[client_name]&nbsp;&nbsp;=> mypic.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_ext]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> .jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_size]&nbsp;&nbsp;&nbsp;&nbsp;=> 22.2<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[is_image]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 1<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_width]&nbsp;&nbsp;=> 800<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_height] => 600<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_type]&nbsp;&nbsp;&nbsp;=> jpeg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_size_str] => width="800" height="200"<br />

-<h1>Overview</h1>
-
-
-<p>Before explaining CodeIgniter's approach to data validation, let's describe the ideal scenario:</p>
-
-<ol>
-<li>A form is displayed.</li>
-<li>You fill it in and submit it.</li>
-<li>If you submitted something invalid, or perhaps missed a required item, the form is redisplayed containing your data
-along with an error message describing the problem.</li>
-<li>This process continues until you have submitted a valid form.</li>
-</ol>
-
-<p>On the receiving end, the script must:</p>
-
-<ol>
-<li>Check for required data.</li>
-<li>Verify that the data is of the correct type, and meets the correct criteria. For example, if a username is submitted
-it must be validated to contain only permitted characters.  It must be of a minimum length,
-and not exceed a maximum length. The username can't be someone else's existing username, or perhaps even a reserved word. Etc.</li>
-<li>Sanitize the data for security.</li>
-<li>Pre-format the data if needed (Does the data need to be trimmed?  HTML encoded?  Etc.)</li>
-<li>Prep the data for insertion in the database.</li>
-</ol>
-
-
-<p>Although there is nothing terribly complex about the above process, it usually requires a significant
-amount of code, and to display error messages, various control structures are usually placed within the form HTML.
-Form validation, while simple to create, is generally very messy and tedious to implement.</p>
-
-<p>&nbsp;</p>
-
-
-<a name="tutorial"></a>
-<h1>Form Validation Tutorial</h1>
-
-<p>What follows is a "hands on" tutorial for implementing CodeIgniters Form Validation.</p>
-
-
-<p>In order to implement form validation you'll need three things:</p>
-
-<ol>
-<li>A <a href="../general/views.html">View</a> file containing a form.</li>
-<li>A View file containing a "success" message to be displayed upon successful submission.</li>
-<li>A <a href="../general/controllers.html">controller</a> function to receive and process the submitted data.</li>

-
-<p>Let's create those three things, using a member sign-up form as the example.</p>
-
-

-<a name="theform"></a>
-
-<h2>The Form</h2>
-
-<p>Using a text editor, create a form called <dfn>myform.php</dfn>.  In it, place this code and save it to your <samp>applications/views/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="30">&lt;html>
-&lt;head>
-&lt;title>My Form&lt;/title>

-
-&lt;?php echo validation_errors(); ?>
-
-&lt;?php echo form_open('form'); ?>

-&lt;h5>Username&lt;/h5>
-&lt;input type="text" name="username" value="" size="50" />
-
-&lt;h5>Password&lt;/h5>
-&lt;input type="text" name="password" value="" size="50" />
-
-&lt;h5>Password Confirm&lt;/h5>
-&lt;input type="text" name="passconf" value="" size="50" />

-
-
-<a name="thesuccesspage"></a>
-<h2>The Success Page</h2>
-
-
-<p>Using a text editor, create a form called <dfn>formsuccess.php</dfn>.  In it, place this code and save it to your <samp>applications/views/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="14">
-&lt;html>
-&lt;head>
-&lt;title>My Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;h3>Your form was successfully submitted!&lt;/h3>
-
-&lt;p>&lt;?php echo anchor('form', 'Try it again!'); ?>&lt;/p>
-
-&lt;/body>
-&lt;/html>
-</textarea>
-
-
-
-<a name="thecontroller"></a>
-<h2>The Controller</h2>
-
-<p>Using a text editor, create a controller called <dfn>form.php</dfn>.  In it, place this code and save it to your <samp>applications/controllers/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="21">&lt;?php
-
-class Form extends CI_Controller {
-
-	function index()
-	{
-		$this->load->helper(array('form', 'url'));
-
-		$this->load->library('form_validation');
-
-		if ($this->form_validation->run() == FALSE)
-		{
-			$this->load->view('myform');
-		}
-		else
-		{
-			$this->load->view('formsuccess');
-		}
-	}
-}
-?></textarea>
-
-
-<h2>Try it!</h2>
-
-<p>To try your form, visit your site using a URL similar to this one:</p>
-
-<code>example.com/index.php/<var>form</var>/</code>
-
-<p><dfn>If you submit the form you should simply see the form reload.  That's because you haven't set up any validation
-rules yet.</dfn></p>
-
-<p><strong>Since you haven't told the Form Validation class to validate anything yet, it returns <kbd>FALSE</kbd> (boolean false) by default.  The <samp>run()</samp>
-function only returns <kbd>TRUE</kbd> if it has successfully applied your rules without any of them failing.</strong></p>
-
-
-<h2>Explanation</h2>
-
-<p>You'll notice several things about the above pages:</p>
-
-<p>The <dfn>form</dfn> (myform.php) is a standard web form with a couple exceptions:</p>
-
-<ol>
-<li>It uses a <dfn>form helper</dfn> to create the form opening.
-Technically, this isn't necessary.  You could create the form using standard HTML.  However, the benefit of using the helper
-is that it generates the action URL for you, based on the URL in your config file.  This makes your application more portable in the event your URLs change.</li>
-
-<li>At the top of the form you'll notice the following function call:
-<code>&lt;?php echo validation_errors(); ?&gt;</code>
-
-<p>This function will return any error messages sent back by the validator. If there are no messages it returns an empty string.</p>
-</li>
-</ol>
-
-<p>The <dfn>controller</dfn> (form.php) has one function: <dfn>index()</dfn>. This function initializes the validation class and
-loads the <var>form helper</var> and <var>URL helper</var> used by your view files. It also <samp>runs</samp>
-the validation routine. Based on
-whether the validation was successful it either presents the form or the success page.</p>
-
-
-
-
-<a name="validationrules"></a>
-
-<h2>Setting Validation Rules</h2>
-
-<p>CodeIgniter lets you set as many validation rules as you need for a given field, cascading them in order, and it even lets you prep and pre-process the field data
-at the same time. To set validation rules you will use the <dfn>set_rules()</dfn> function:</p>
-
-<code>$this->form_validation->set_rules();</code>
-
-<p>The above function takes <strong>three</strong> parameters as input:</p>
-
-<ol>
-	<li>The field name - the exact name you've given the form field.</li>
-	<li>A "human" name for this field, which will be inserted into the error message. For example, if your field is named "user" you might give it a human name of "Username". <strong>Note:</strong> If you would like the field name to be stored in a language file, please see <a href="#translatingfn">Translating Field Names</a>.</li>
-	<li>The validation rules for this form field.</li>
-</ol>
-
-
-<p><br />Here is an example. In your <dfn>controller</dfn> (form.php), add this code just below the validation initialization function:</p>
-
-<code>
-$this->form_validation->set_rules('username', 'Username', 'required');<br />
-$this->form_validation->set_rules('password', 'Password', 'required');<br />
-$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');<br />
-$this->form_validation->set_rules('email', 'Email', 'required');<br />
-</code>
-
-<p>Your controller should now look like this:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="28">&lt;?php
-
-class Form extends CI_Controller {
-
-	function index()
-	{
-		$this->load->helper(array('form', 'url'));
-
-		$this->load->library('form_validation');
-
-		$this->form_validation->set_rules('username', 'Username', 'required');
-		$this->form_validation->set_rules('password', 'Password', 'required');
-		$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
-		$this->form_validation->set_rules('email', 'Email', 'required');
-
-		if ($this->form_validation->run() == FALSE)
-		{
-			$this->load->view('myform');
-		}
-		else
-		{
-			$this->load->view('formsuccess');
-		}
-	}
-}
-?></textarea>
-
-<p><dfn>Now submit the form with the fields blank and you should see the error messages.
-If you submit the form with all the fields populated you'll see your success page.</dfn></p>
-
-<p class="important"><strong>Note:</strong> The form fields are not yet being re-populated with the data when
-there is an error.  We'll get to that shortly.</p>

-<h2>Setting Rules Using an Array</h2>
-
-<p>Before moving on it should be noted that the rule setting function can be passed an array if you prefer to set all your rules in one action.
-If you use this approach you must name your array keys as indicated:</p>
-
-<code>
-$config = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'username', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Username', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'password', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Password', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'passconf', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Password Confirmation', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'email', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Email', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->form_validation->set_rules($config);
-</code>
-
-
-
-
-
-
-<a name="cascadingrules"></a>
-<h2>Cascading Rules</h2>
-
-<p>CodeIgniter lets you pipe multiple rules together.  Let's try it. Change your rules in the third parameter of rule setting function, like this:</p>
-
-<code>
-$this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[12]|is_unique[users.username]');<br />
-$this->form_validation->set_rules('password', 'Password', 'required|matches[passconf]');<br />
-$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');<br />
-$this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[users.email]');<br />
-</code>
-
-<p>The above code sets the following rules:</p>
-
-<ol>
-<li>The username field be no shorter than 5 characters and no longer than 12.</li>
-<li>The password field must match the password confirmation field.</li>
-<li>The email field must contain a valid email address.</li>
-</ol>
-
-<p>Give it a try! Submit your form without the proper data and you'll see new error messages that correspond to your new rules.
-There are numerous rules available which you can read about in the validation reference.</p>
-
-
-
-<a name="preppingdata"></a>
-<h2>Prepping Data</h2>
-
-<p>In addition to the validation functions like the ones we used above, you can also prep your data in various ways.
-For example, you can set up rules like this:</p>
-
-<code>
-$this->form_validation->set_rules('username', 'Username', '<kbd>trim</kbd>|required|min_length[5]|max_length[12]|<kbd>xss_clean</kbd>');<br />
-$this->form_validation->set_rules('password', 'Password', '<kbd>trim</kbd>|required|matches[passconf]|<kbd>md5</kbd>');<br />
-$this->form_validation->set_rules('passconf', 'Password Confirmation', '<kbd>trim</kbd>|required');<br />
-$this->form_validation->set_rules('email', 'Email', '<kbd>trim</kbd>|required|valid_email');<br />
-</code>
-
-
-<p>In the above example, we are "trimming" the fields, converting the password to MD5, and running the username through
-the "xss_clean" function, which removes malicious data.</p>
-
-<p><strong>Any native PHP function that accepts one parameter can be used as a rule, like <dfn>htmlspecialchars</dfn>,
-<dfn>trim</dfn>,  <dfn>MD5</dfn>, etc.</strong></p>
-
-<p><strong>Note:</strong> You will generally want to use the prepping functions <strong>after</strong>
-the validation rules so if there is an error, the original data will be shown in the form.</p>
-
-
-
-
-<a name="repopulatingform"></a>
-<h2>Re-populating the form</h2>
-
-<p>Thus far we have only been dealing with errors.  It's time to repopulate the form field with the submitted data. CodeIgniter offers several helper functions
-that permit you to do this. The one you will use most commonly is:</p>
-
-<code>set_value('field name')</code>
-
-
-<p>Open your <dfn>myform.php</dfn> view file and update the <strong>value</strong> in each field using the <dfn>set_value()</dfn> function:</p>
-
-<p><strong>Don't forget to include each field name in the <dfn>set_value()</dfn> functions!</strong></p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="30">
-&lt;html>
-&lt;head>
-&lt;title>My Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;?php echo validation_errors(); ?>
-
-&lt;?php echo form_open('form'); ?>
-
-&lt;h5>Username&lt;/h5>
-&lt;input type="text" name="username" value="&lt;?php echo set_value('username'); ?>" size="50" />
-
-&lt;h5>Password&lt;/h5>
-&lt;input type="text" name="password" value="&lt;?php echo set_value('password'); ?>" size="50" />
-
-&lt;h5>Password Confirm&lt;/h5>
-&lt;input type="text" name="passconf" value="&lt;?php echo set_value('passconf'); ?>" size="50" />
-
-&lt;h5>Email Address&lt;/h5>
-&lt;input type="text" name="email" value="&lt;?php echo set_value('email'); ?>" size="50" />
-
-&lt;div>&lt;input type="submit" value="Submit" />&lt;/div>
-
-&lt;/form>
-
-&lt;/body>
-&lt;/html>
-</textarea>
-
-
-<p><dfn>Now reload your page and submit the form so that it triggers an error.  Your form fields should now be re-populated</dfn></p>
-
-<p class="important"><strong>Note:</strong> The <a href="#functionreference">Function Reference</a> section below contains functions that
-permit you to re-populate &lt;select> menus, radio buttons, and checkboxes.</p>
-
-
-<p><strong>Important Note:</strong> If you use an array as the name of a form field, you must supply it as an array to the function.  Example:</p>
-
-<code>&lt;input type="text" name="<kbd>colors[]</kbd>" value="&lt;?php echo set_value('<kbd>colors[]</kbd>'); ?>" size="50" /></code>
-
-<p>For more info please see the <a href="#arraysasfields">Using Arrays as Field Names</a> section below.</p>
-
-
-
-
-
-<a name="callbacks"></a>
-<h2>Callbacks: Your own Validation Functions</h2>
-
-<p>The validation system supports callbacks to your own validation functions.  This permits you to extend the validation class
-to meet your needs.  For example, if you need to run a database query to see if the user is choosing a unique username, you can
-create a callback function that does that.  Let's create a example of this.</p>
-
-<p>In your controller, change the "username" rule to this:</p>
-
-<code>$this->form_validation->set_rules('username', 'Username', '<kbd>callback_username_check</kbd>');</code>
-
-<p>Then add a new function called <dfn>username_check</dfn> to your controller.  Here's how your controller should now look:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="40">&lt;?php
-
-class Form extends CI_Controller {
-
-	public function index()
-	{
-		$this->load->helper(array('form', 'url'));
-
-		$this->load->library('form_validation');
-
-		$this->form_validation->set_rules('username', 'Username', 'callback_username_check');
-		$this->form_validation->set_rules('password', 'Password', 'required');
-		$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
-		$this->form_validation->set_rules('email', 'Email', 'required|is_unique[users.email]');
-
-		if ($this->form_validation->run() == FALSE)
-		{
-			$this->load->view('myform');
-		}
-		else
-		{
-			$this->load->view('formsuccess');
-		}
-	}
-
-	public function username_check($str)
-	{
-		if ($str == 'test')
-		{
-			$this->form_validation->set_message('username_check', 'The %s field can not be the word "test"');
-			return FALSE;
-		}
-		else
-		{
-			return TRUE;
-		}
-	}
-
-}
-?></textarea>
-
-<p><dfn>Reload your form and submit it with the word "test" as the username.  You can see that the form field data was passed to your
-callback function for you to process.</dfn></p>
-
-<p>To invoke a callback just put the function name in a rule, with "callback_" as the rule <strong>prefix</strong>. If you need
-to receive an extra parameter in your callback function, just add it normally after the function name between square brackets,
-as in: "callback_foo<strong>[bar]</strong>", then it will be passed as the second argument of your callback function.</p>
-
-<p><strong>Note:</strong> You can also process the form data that is passed to your callback and return it.  If your callback returns anything other than a boolean TRUE/FALSE
-it is assumed that the data is your newly processed form data.</p>
-
-<a name="settingerrors"></a>
-<h2>Setting Error Messages</h2>
-
-
-<p>All of the native error messages are located in the following language file:  <dfn>language/english/form_validation_lang.php</dfn></p>
-
-<p>To set your own custom message you can either edit that file, or use the following function:</p>
-
-<code>$this->form_validation->set_message('<var>rule</var>', '<var>Error Message</var>');</code>
-
-<p>Where <var>rule</var> corresponds to the name of a particular rule, and <var>Error Message</var> is the text you would like displayed.</p>
-
-<p>If you include <dfn>%s</dfn> in your error string, it will be replaced with the "human" name you used for your field when you set your rules.</p>
-
-<p>In the "callback" example above, the error message was set by passing the name of the function:</p>
-
-<code>$this->form_validation->set_message('username_check')</code>
-
-<p>You can also override any error message found in the language file.  For example, to change the message for the "required" rule you will do this:</p>
-
-<code>$this->form_validation->set_message('required', 'Your custom message here');</code>
-
-
-
-<a name="translatingfn"></a>
-<h2>Translating Field Names</h2>
-
-<p>If you would like to store the "human" name you passed to the <dfn>set_rules()</dfn> function in a language file, and therefore make the name able to be translated, here's how:</p>
-
-<p>First, prefix your "human" name with <dfn>lang:</dfn>, as in this example:</p>
-
-<code>
-$this->form_validation->set_rules('first_name', '<kbd>lang:</kbd>first_name', 'required');<br />
-</code>
-
-<p>Then, store the name in one of your language file arrays (without the prefix):</p>
-
-<code>$lang['first_name'] = 'First Name';</code>
-
-<p><strong>Note:</strong> If you store your array item in a language file that is not loaded automatically by CI, you'll need to remember to load it in your controller using:</p>
-
-<code>$this->lang->load('file_name');</code>
-
-<p>See the <a href="language.html">Language Class</a> page for more info regarding language files.</p>
-
-
-<a name="errordelimiters"></a>
-<h2>Changing the Error Delimiters</h2>
-
-<p>By default, the Form Validation class adds a paragraph tag (&lt;p&gt;) around each error message shown. You can either change these delimiters globally or
-individually.</p>
-
-<ol>
-
-<li><strong>Changing delimiters Globally</strong>
-
-<p>To globally change the error delimiters, in your controller function, just after loading the Form Validation class, add this:</p>
-
-<code>$this->form_validation->set_error_delimiters('<kbd>&lt;div class="error"></kbd>', '<kbd>&lt;/div></kbd>');</code>
-
-<p>In this example, we've switched to using div tags.</p>
-
-</li>
-
-<li><strong>Changing delimiters Individually</strong>
-
-<p>Each of the two error generating functions shown in this tutorial can be supplied their own delimiters as follows:</p>
-
-<code>&lt;?php echo form_error('field name', '<kbd>&lt;div class="error"></kbd>', '<kbd>&lt;/div></kbd>'); ?></code>
-
-<p>Or:</p>
-
-<code>&lt;?php echo validation_errors('<kbd>&lt;div class="error"></kbd>', '<kbd>&lt;/div></kbd>'); ?></code>
-
-</li>
-</ol>
-
-
-
-
-<a name="individualerrors"></a>
-<h2>Showing Errors Individually</h2>
-
-<p>If you prefer to show an error message next to each form field, rather than as a list, you can use the <dfn>form_error()</dfn> function.</p>
-
-<p>Try it! Change your form so that it looks like this:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="18">
-&lt;h5>Username&lt;/h5>
-&lt;?php echo form_error('username'); ?>
-&lt;input type="text" name="username" value="&lt;?php echo set_value('username'); ?>" size="50" />
-
-&lt;h5>Password&lt;/h5>
-&lt;?php echo form_error('password'); ?>
-&lt;input type="text" name="password" value="&lt;?php echo set_value('password'); ?>" size="50" />
-
-&lt;h5>Password Confirm&lt;/h5>
-&lt;?php echo form_error('passconf'); ?>
-&lt;input type="text" name="passconf" value="&lt;?php echo set_value('passconf'); ?>" size="50" />
-
-&lt;h5>Email Address&lt;/h5>
-&lt;?php echo form_error('email'); ?>
-&lt;input type="text" name="email" value="&lt;?php echo set_value('email'); ?>" size="50" />
-</textarea>
-
-<p>If there are no errors, nothing will be shown.  If there is an error, the message will appear.</p>
-
-<p><strong>Important Note:</strong> If you use an array as the name of a form field, you must supply it as an array to the function.  Example:</p>
-
-<code>&lt;?php echo form_error('<kbd>options[size]</kbd>'); ?><br />
-&lt;input type="text" name="<kbd>options[size]</kbd>" value="&lt;?php echo set_value("<kbd>options[size]</kbd>"); ?>" size="50" />

-<h1>Saving Sets of Validation Rules to a Config File</h1>
-
-<p>A nice feature of the Form Validation class is that it permits you to store all your validation rules for your entire application in a config file.  You
-can organize these rules into "groups".  These groups can either be loaded automatically when a matching controller/function is called, or
-you can manually call each set as needed.</p>
-
-<h3>How to save your rules</h3>
-
-<p>To store your validation rules, simply create a file named <kbd>form_validation.php</kbd> in your <dfn>application/config/</dfn> folder.
-In that file you will place an array named <kbd>$config</kbd> with your rules. As shown earlier, the validation array will have this prototype:</p>
-
-<code>
-$config = array(<br />

-<h3>Creating Sets of Rules</h3>
-
-<p>In order to organize your rules into "sets" requires that you place them into "sub arrays".  Consider the following example, showing two sets of rules.
-We've arbitrarily called these two rules "signup" and "email".  You can name your rules anything you want:</p>
-
-
-<code>$config = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'<kbd>signup</kbd>' => array(<br />

-<h3>Calling a Specific Rule Group</h3>
-
-<p>In order to call a specific group you will pass its name to the <kbd>run()</kbd> function.  For example, to call the <kbd>signup</kbd> rule you will do this:</p>
-
-<code>
-if ($this->form_validation->run('<kbd>signup</kbd>') == FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;$this->load->view('myform');<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;$this->load->view('formsuccess');<br />
-}<br />
-</code>
-
-
-
-<h3>Associating a Controller Function with a Rule Group</h3>
-
-<p>An alternate (and more automatic) method of calling a rule group is to name it according to the controller class/function you intend to use it with.  For example, let's say you
-have a controller named <kbd>Member</kbd> and a function named <kbd>signup</kbd>.  Here's what your class might look like:</p>
-
-<code>
-&lt;?php<br /><br />
-class <kbd>Member</kbd> extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;function <kbd>signup</kbd>()<br />
-&nbsp;&nbsp;&nbsp;{&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->library('form_validation');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if ($this->form_validation->run() == FALSE)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('myform');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;else<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('formsuccess');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;}<br />
-}<br />
-?></code>
-
-<p>In your validation config file, you will name your rule group <kbd>member/signup</kbd>:</p>
-
-
-<code>$config = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'<kbd>member/signup</kbd>' => array(<br />

-<h1>Using Arrays as Field Names</h1>
-
-<p>The Form Validation class supports the use of arrays as field names.  Consider this example:</p>
-
-<code>&lt;input type="text" name="<kbd>options[]</kbd>" value="" size="50" /></code>
-
-<p>If you do use an array as a field name, you must use the EXACT array name in the <a href="#helperreference">Helper Functions</a> that require the field name,
-and as your Validation Rule field name.</p>
-
-<p>For example, to set a rule for the above field you would use:</p>
-
-<code>$this->form_validation->set_rules('<kbd>options[]</kbd>', 'Options', 'required');</code>
-
-<p>Or, to show an error for the above field you would use:</p>
-
-<code>&lt;?php echo form_error('<kbd>options[]</kbd>'); ?></code>
-
-<p>Or to re-populate the field you would use:</p>
-
-<code>&lt;input type="text" name="<kbd>options[]</kbd>" value="<kbd>&lt;?php echo set_value('<kbd>options[]</kbd>'); ?></kbd>" size="50" /></code>
-
-<p>You can use multidimensional arrays as field names as well. For example:</p>
-
-<code>&lt;input type="text" name="<kbd>options[size]</kbd>" value="" size="50" /></code>
-
-<p>Or even:</p>
-
-<code>&lt;input type="text" name="<kbd>sports[nba][basketball]</kbd>" value="" size="50" /></code>
-
-<p>As with our first example, you must use the exact array name in the helper functions:</p>
-
-<code>&lt;?php echo form_error('<kbd>sports[nba][basketball]</kbd>'); ?></code>
-
-<p>If you are using checkboxes (or other fields) that have multiple options, don't forget to leave an empty bracket after each option, so that all selections will be added to the
-POST array:</p>
-
-<code>
-&lt;input type="checkbox" name="<kbd>options[]</kbd>" value="red" /><br />
-&lt;input type="checkbox" name="<kbd>options[]</kbd>" value="blue" /><br />
-&lt;input type="checkbox" name="<kbd>options[]</kbd>" value="green" />
-</code>
-
-<p>Or if you use a multidimensional array:</p>
-
-<code>
-&lt;input type="checkbox" name="<kbd>options[color][]</kbd>" value="red" /><br />
-&lt;input type="checkbox" name="<kbd>options[color][]</kbd>" value="blue" /><br />
-&lt;input type="checkbox" name="<kbd>options[color][]</kbd>" value="green" />
-</code>
-
-<p>When you use a helper function you'll include the bracket as well:</p>
-
-<code>&lt;?php echo form_error('<kbd>options[color][]</kbd>'); ?></code>

-<h1>Function Reference</h1>
-
-<p>The following functions are intended for use in your controller functions.</p>
-
-<h2>$this->form_validation->set_rules();</h2>
-
-<p>Permits you to set validation rules, as described in the tutorial sections above:</p>
-
-<ul>
-<li><a href="#validationrules">Setting Validation Rules</a></li>
-<li><a href="#savingtoconfig">Saving Groups of Validation Rules to a Config File</a></li>
-</ul>
-
-
-<h2>$this->form_validation->run();</h2>
-
-<p>Runs the validation routines.  Returns boolean TRUE on success and FALSE on failure. You can optionally pass the name of the validation
-group via the function, as described in: <a href="#savingtoconfig">Saving Groups of Validation Rules to a Config File</a>.</p>
-
-
-<h2>$this->form_validation->set_message();</h2>
-
-<p>Permits you to set custom error messages.  See <a href="#settingerrors">Setting Error Messages</a> above.</p>
-
-
-<p>&nbsp;</p>
-
-<a name="helperreference"></a>
-<h1>Helper Reference</h1>
-
-<p>The following helper functions are available for use in the view files containing your forms.  Note that these are procedural functions, so they
-<strong>do not</strong> require you to prepend them with $this->form_validation.</p>
-
-<h2>form_error()</h2>
-
-<p>Shows an individual error message associated with the field name supplied to the function.  Example:</p>
-
-<code>&lt;?php echo form_error('username'); ?></code>
-
-<p>The error delimiters can be optionally specified.  See the <a href="#errordelimiters">Changing the Error Delimiters</a> section above.</p>
-
-
-
-<h2>validation_errors()</h2>
-<p>Shows all error messages as a string:  Example:</p>
-
-<code>&lt;?php echo validation_errors(); ?></code>
-
-<p>The error delimiters can be optionally specified.  See the <a href="#errordelimiters">Changing the Error Delimiters</a> section above.</p>
-
-
-
-<h2>set_value()</h2>
-
-<p>Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function.
-The second (optional) parameter allows you to set a default value for the form. Example:</p>
-
-<code>&lt;input type="text" name="quantity" value="<dfn>&lt;?php echo set_value('quantity', '0'); ?></dfn>" size="50" /></code>
-
-<p>The above form will show "0" when loaded for the first time.</p>
-
-<h2>set_select()</h2>
-
-<p>If you use a <dfn>&lt;select></dfn> menu, this function permits you to display the menu item that was selected.  The first parameter
-must contain the name of the select menu, the second parameter must contain the value of
-each item, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE).</p>
-
-<p>Example:</p>
-
-<code>
-&lt;select name="myselect"><br />
-&lt;option value="one" <dfn>&lt;?php echo  set_select('myselect', 'one', TRUE); ?></dfn> >One&lt;/option><br />
-&lt;option value="two" <dfn>&lt;?php echo  set_select('myselect', 'two'); ?></dfn> >Two&lt;/option><br />
-&lt;option value="three" <dfn>&lt;?php echo  set_select('myselect', 'three'); ?></dfn> >Three&lt;/option><br />
-&lt;/select>
-</code>
-
-
-<h2>set_checkbox()</h2>
-
-<p>Permits you to display a checkbox in the state it was submitted.  The first parameter
-must contain the name of the checkbox, the second parameter must contain its value, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE). Example:</p>
-
-<code>&lt;input type="checkbox" name="mycheck[]" value="1" <dfn>&lt;?php echo set_checkbox('mycheck[]', '1'); ?></dfn> /><br />
-&lt;input type="checkbox" name="mycheck[]" value="2" <dfn>&lt;?php echo set_checkbox('mycheck[]', '2'); ?></dfn> /></code>
-
-
-<h2>set_radio()</h2>
-
-<p>Permits you to display radio buttons in the state they were submitted. This function is identical to the <strong>set_checkbox()</strong> function above.</p>
-
-<code>&lt;input type="radio" name="myradio" value="1" <dfn>&lt;?php echo  set_radio('myradio', '1', TRUE); ?></dfn> /><br />
-&lt;input type="radio" name="myradio" value="2" <dfn>&lt;?php echo  set_radio('myradio', '2'); ?></dfn> /></code>

-<h1>FTP Class</h1>
-
-<p>CodeIgniter's FTP Class permits files to be transfered to a remote server. Remote files can also be moved, renamed,
-and deleted.  The FTP class also includes a "mirroring" function that permits an entire local directory to be recreated remotely via FTP.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; SFTP and SSL FTP protocols are not supported, only standard FTP.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the FTP class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('ftp');</code>
-<p>Once loaded, the FTP object will be available using: <dfn>$this->ftp</dfn></p>
-
-
-<h2>Usage Examples</h2>
-
-<p>In this example a connection is opened to the FTP server, and a local file is read and uploaded in ASCII mode. The
-file permissions are set to 755.  Note: Setting permissions requires PHP 5.</p>
-
-<code>
-$this->load->library('ftp');<br />
-<br />
-$config['hostname'] = 'ftp.example.com';<br />
-$config['username'] = 'your-username';<br />
-$config['password'] = 'your-password';<br />
-$config['debug']	= TRUE;<br />
-<br />
-$this->ftp->connect($config);<br />
-<br />
-$this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775);<br />
-<br />
-$this->ftp->close();
-
-</code>
-
-
-<p>In this example a list of files is retrieved from the server.</p>
-
-<code>
-$this->load->library('ftp');<br />
-<br />
-$config['hostname'] = 'ftp.example.com';<br />
-$config['username'] = 'your-username';<br />
-$config['password'] = 'your-password';<br />
-$config['debug']	= TRUE;<br />
-<br />
-$this->ftp->connect($config);<br />
-<br />
-$list = $this->ftp->list_files('/public_html/');<br />
-<br />
-print_r($list);<br />
-<br />
-$this->ftp->close();
-</code>
-
-<p>In this example a local directory is mirrored on the server.</p>
-
-
-<code>
-$this->load->library('ftp');<br />
-<br />
-$config['hostname'] = 'ftp.example.com';<br />
-$config['username'] = 'your-username';<br />
-$config['password'] = 'your-password';<br />
-$config['debug']	= TRUE;<br />
-<br />
-$this->ftp->connect($config);<br />
-<br />
-$this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/');<br />
-<br />
-$this->ftp->close();
-</code>
-
-
-<h1>Function Reference</h1>
-
-<h2>$this->ftp->connect()</h2>
-
-<p>Connects and logs into to the FTP server. Connection preferences are set by passing an array
-to the function, or you can store them in a config file.</p>
-
-
-<p>Here is an example showing how you set preferences manually:</p>
-
-<code>
-$this->load->library('ftp');<br />
-<br />
-$config['hostname'] = 'ftp.example.com';<br />
-$config['username'] = 'your-username';<br />
-$config['password'] = 'your-password';<br />
-$config['port']&nbsp;&nbsp;&nbsp;&nbsp; = 21;<br />
-$config['passive']&nbsp;&nbsp;= FALSE;<br />
-$config['debug']&nbsp;&nbsp;&nbsp;&nbsp;= TRUE;<br />
-<br />
-$this->ftp->connect($config);<br />
-</code>
-
-<h3>Setting FTP Preferences in a Config File</h3>
-
-<p>If you prefer you can store your FTP preferences in a config file.
-Simply create a new file called the <var>ftp.php</var>,  add the <var>$config</var>
-array in that file. Then save the file at <var>config/ftp.php</var> and it will be used automatically.</p>
-
-<h3>Available connection options:</h3>
-
-
-<ul>
-<li><strong>hostname</strong> - the FTP hostname.  Usually something like:&nbsp; <dfn>ftp.example.com</dfn></li>
-<li><strong>username</strong> - the FTP username.</li>
-<li><strong>password</strong> - the FTP password.</li>
-<li><strong>port</strong> - The port number. Set to <dfn>21</dfn> by default.</li>
-<li><strong>debug</strong> - <kbd>TRUE/FALSE</kbd> (boolean). Whether to enable debugging to display error messages.</li>
-<li><strong>passive</strong> - <kbd>TRUE/FALSE</kbd> (boolean). Whether to use passive mode.  Passive is set automatically by default.</li>
-</ul>
-
-
-
-<h2>$this->ftp->upload()</h2>
-
-<p>Uploads a file to your server.  You must supply the local path and the remote path, and you can optionally set the mode and permissions.
-Example:</p>
-
-
-<code>$this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775);</code>
-
-<p><strong>Mode options are:</strong>&nbsp; <kbd>ascii</kbd>, <kbd>binary</kbd>, and <kbd>auto</kbd> (the default). If
-<kbd>auto</kbd> is used it will base the mode on the file extension of the source file.</p>
-
-<p>Permissions are available if you are running PHP 5 and can be passed as an <kbd>octal</kbd> value in the fourth parameter.</p>
-
-
-<h2>$this->ftp->download()</h2>
-
-<p>Downloads a file from your server.  You must supply the remote path and the local path, and you can optionally set the mode.
-Example:</p>
-
-<code>$this->ftp->download('/public_html/myfile.html', '/local/path/to/myfile.html', 'ascii');</code>
-
-<p><strong>Mode options are:</strong>&nbsp; <kbd>ascii</kbd>, <kbd>binary</kbd>, and <kbd>auto</kbd> (the default). If
-<kbd>auto</kbd> is used it will base the mode on the file extension of the source file.</p>
-
-<p>Returns FALSE if the download does not execute successfully (including if PHP does not have permission to write the local file)</p>
-
-
-<h2>$this->ftp->rename()</h2>
-<p>Permits you to rename a file.  Supply the source file name/path and the new file name/path.</p>
-
-<code>
-// Renames green.html to blue.html<br />
-$this->ftp->rename('/public_html/foo/green.html', '/public_html/foo/blue.html');
-</code>
-
-<h2>$this->ftp->move()</h2>
-<p>Lets you move a file.  Supply the source and destination paths:</p>
-
-<code>
-// Moves blog.html from "joe" to "fred"<br />
-$this->ftp->move('/public_html/joe/blog.html', '/public_html/fred/blog.html');
-</code>
-
-<p>Note: if the destination file name is different the file will be renamed.</p>
-
-
-<h2>$this->ftp->delete_file()</h2>
-<p>Lets you delete a file.  Supply the source path with the file name.</p>
-
-<code>
-$this->ftp->delete_file('/public_html/joe/blog.html');
-</code>
-
-
-<h2>$this->ftp->delete_dir()</h2>
-<p>Lets you delete a directory and everything it contains.  Supply the source path to the directory with a trailing slash.</p>
-
-<p class="important"><strong>Important</strong>&nbsp; Be VERY careful with this function.  It will recursively delete
-<b>everything</b> within the supplied path, including sub-folders and all files.  Make absolutely sure your path is correct.
-Try using the <kbd>list_files()</kbd> function first to verify that your path is correct.</p>
-
-<code>
-$this->ftp->delete_dir('/public_html/path/to/folder/');
-</code>
-
-
-
-<h2>$this->ftp->list_files()</h2>
-<p>Permits you to retrieve a list of files on your server returned as an <dfn>array</dfn>.  You must supply
-the path to the desired directory.</p>
-
-<code>
-$list = $this->ftp->list_files('/public_html/');<br />
-<br />
-print_r($list);
-</code>
-
-
-<h2>$this->ftp->mirror()</h2>
-
-<p>Recursively reads a local folder and everything it contains (including sub-folders) and creates a
-mirror via FTP based on it.  Whatever the directory structure of the original file path will be recreated on the server.
-You must supply a source path and a destination path:</p>
-
-<code>
-$this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/');
-</code>
-
-
-
-<h2>$this->ftp->mkdir()</h2>
-
-<p>Lets you create a directory on your server.  Supply the path ending in the folder name you wish to create, with a trailing slash.
-Permissions can be set by passed an <kbd>octal</kbd> value in the second parameter (if you are running PHP 5).</p>
-
-<code>
-// Creates a folder named "bar"<br />
-$this->ftp->mkdir('/public_html/foo/bar/', DIR_WRITE_MODE);
-</code>
-
-
-<h2>$this->ftp->chmod()</h2>
-
-<p>Permits you to set file permissions.  Supply the path to the file or folder you wish to alter permissions on:</p>
-
-<code>
-// Chmod "bar" to 777<br />
-$this->ftp->chmod('/public_html/foo/bar/', DIR_WRITE_MODE);
-</code>
-
-
-
-
-<h2>$this->ftp->close();</h2>
-<p>Closes the connection to your server.  It's recommended that you use this when you are finished uploading.</p>

-<h1>Image Manipulation Class</h1>
-
-<p>CodeIgniter's Image Manipulation class lets you perform the following actions:</p>
-
-<ul>
-<li>Image Resizing</li>
-<li>Thumbnail Creation</li>
-<li>Image Cropping</li>
-<li>Image Rotating</li>
-<li>Image Watermarking</li>
-</ul>
-
-<p>All three major image libraries are supported:  GD/GD2, NetPBM, and ImageMagick</p>
-
-<p class="important"><strong>Note:</strong> Watermarking is only available using the GD/GD2 library.
-In addition, even though other libraries are supported, GD is required in
-order for the script to calculate the image properties.  The image processing, however, will be performed with the
-library you specify.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the image class is initialized in your controller
-using the <dfn>$this->load-&gt;library</dfn> function:</p>
-<code>$this->load->library('image_lib');</code>
-
-<p>Once the library is loaded it will be ready for use.  The image library object you will use to call all functions is: <dfn>$this->image_lib</dfn></p>
-
-
-<h2>Processing an Image</h2>
-
-<p>Regardless of the type of processing you would like to perform (resizing, cropping, rotation, or watermarking), the general process is
-identical. You will set some preferences corresponding to the action you intend to perform, then
-call one of four available processing functions.  For example, to create an image thumbnail you'll do this:</p>
-
-<code>$config['image_library'] = 'gd2';<br />
-$config['source_image']	= '/path/to/image/mypic.jpg';<br />
-$config['create_thumb'] = TRUE;<br />
-$config['maintain_ratio'] = TRUE;<br />
-$config['width']		= 75;<br />
-$config['height']	= 50;<br />
-<br />
-$this->load->library('image_lib', $config);
-<br />
-<br />
-$this->image_lib->resize();</code>
-
-<p>The above code tells the <dfn>image_resize</dfn> function to look for an image called <em>mypic.jpg</em>
-located in the <dfn>source_image</dfn> folder, then create a thumbnail that is 75 X 50 pixels using the GD2 <dfn>image_library</dfn>.
-Since the <dfn>maintain_ratio</dfn> option is enabled, the thumb will be as close to the target <dfn>width</dfn> and
-<dfn>height</dfn> as possible while preserving the original aspect ratio.  The thumbnail will be called <em>mypic_thumb.jpg</em>
-</p>
-
-<p class="important"><strong>Note:</strong> In order for the image class to be allowed to do any processing, the
-folder containing the image files must have write permissions.</p>
-
-<p class="important"><strong>Note:</strong> Image processing can require a considerable amount of server memory for some operations. If you are experiencing out of memory errors while processing images you may need to limit their maximum size, and/or adjust PHP memory limits.</p>
-
-<h2>Processing Functions</h2>
-
-<p>There are four available processing functions:</p>
-
-<ul>
-<li>$this->image_lib->resize()</li>
-<li>$this->image_lib->crop()</li>
-<li>$this->image_lib->rotate()</li>
-<li>$this->image_lib->watermark()</li>
-<li>$this-&gt;image_lib-&gt;clear()</li>
-</ul>
-
-<p>These functions return boolean TRUE upon success and FALSE for failure.  If they fail you can retrieve the
-error message using this function:</p>
-
-<code>echo $this->image_lib->display_errors();</code>
-
-<p>A good practice is use the processing function conditionally, showing an error upon failure, like this:</p>
-
-<code>if ( ! $this->image_lib->resize())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $this->image_lib->display_errors();<br />
-}</code>
-
-<p>Note:  You can optionally specify the HTML formatting to be applied to the errors, by submitting the opening/closing
-tags in the function, like this:</p>
-
-<code>$this->image_lib->display_errors('<var>&lt;p></var>', '<var>&lt;/p></var>');</code>
-
-
-<h2>Preferences</h2>
-
-<p>The  preferences described below allow you to tailor the image processing to suit your needs.</p>
-
-<p>Note that not all preferences are available for every
-function.  For example, the x/y axis preferences are only available for image cropping. Likewise, the width and height
-preferences have no effect on cropping.  The "availability" column indicates which functions support a given preference.</p>
-
-<p>Availability Legend:</p>
-
-<ul>
-<li><var>R</var> - Image Resizing</li>
-<li><var>C</var> - Image Cropping</li>
-<li><var>X</var> - Image Rotation</li>

-
-<h2>Setting preferences in a config file</h2>
-
-<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
-Simply create a new file called <var>image_lib.php</var>,  add the <var>$config</var>
-array in that file. Then save the file in: <var>config/image_lib.php</var> and it will be used automatically. You
-will NOT need to use the <dfn>$this->image_lib->initialize</dfn> function if you save your preferences in a config file.</p>
-
-
-<h2>$this->image_lib->resize()</h2>
-
-<p>The image resizing function lets you resize the original image, create a copy (with or without resizing),
-or create a thumbnail image.</p>
-
-<p>For practical purposes there is no difference between creating a copy and creating
-a thumbnail except a thumb will have the thumbnail marker as part of the name (ie, mypic_thumb.jpg).</p>
-
-<p>All preferences listed in the table above are available for this function except these three:  rotation_angle, x_axis, and y_axis.</p>
-
-<h3>Creating a Thumbnail</h3>
-
-<p>The resizing function will create a thumbnail file (and preserve the original) if you set this preference to TRUE:</p>
-
-<code>$config['create_thumb'] = TRUE;</code>
-
-<p>This single preference determines whether a thumbnail is created or not.</p>
-
-<h3>Creating a Copy</h3>
-
-<p>The resizing function will create a copy of the image file (and preserve the original) if you set
-a path and/or a new filename using this preference:</p>
-
-<code>$config['new_image'] = '/path/to/new_image.jpg';</code>
-
-<p>Notes regarding this preference:</p>
-<ul>
-<li>If only the new image name is specified it will be placed in the same folder as the original</li>
-<li>If only the path is specified, the new image will be placed in the destination with the same name as the original.</li>
-<li>If both the path and image name are specified it will placed in its own destination and given the new name.</li>
-</ul>
-
-
-<h3>Resizing the Original Image</h3>
-
-<p>If neither of the two preferences listed above (create_thumb, and new_image) are used, the resizing function will instead
-target the original image for processing.</p>
-
-
-<h2>$this->image_lib->crop()</h2>
-
-<p>The cropping function works nearly identically to the resizing function except it requires that you set
-preferences for the X and Y axis (in pixels) specifying where to crop, like this:</p>
-
-<code>$config['x_axis'] = '100';<br />
-$config['y_axis'] = '40';</code>
-
-<p>All preferences listed in the table above are available for this function except these:  rotation_angle, width, height, create_thumb, new_image.</p>
-
-<p>Here's an example showing how you might crop an image:</p>
-
-<code>$config['image_library'] = 'imagemagick';<br />
-$config['library_path'] = '/usr/X11R6/bin/';<br />
-$config['source_image']	= '/path/to/image/mypic.jpg';<br />
-$config['x_axis'] = '100';<br />
-$config['y_axis'] = '60';<br />
-<br />
-$this->image_lib->initialize($config);
-<br />
-<br />
-if ( ! $this->image_lib->crop())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $this->image_lib->display_errors();<br />
-}</code>
-
-
-<p>Note: Without a visual interface it is difficult to crop images, so this function is not very useful
-unless you intend to build such an interface.  That's exactly what we did using for the photo
-gallery module in ExpressionEngine, the CMS we develop.  We added a JavaScript UI that lets the cropping
-area be selected.</p>
-
-<h2>$this->image_lib->rotate()</h2>
-
-<p>The image rotation function requires that the angle of rotation be set via its preference:</p>
-
-<code>$config['rotation_angle'] = '90';</code>
-
-<p>There are 5 rotation options:</p>
-
-<ol>
-<li>90 - rotates counter-clockwise by 90 degrees.</li>
-<li>180 - rotates counter-clockwise by 180 degrees.</li>
-<li>270 - rotates counter-clockwise by 270 degrees.</li>
-<li>hor - flips the image horizontally.</li>
-<li>vrt - flips the image vertically.</li>
-</ol>
-
-<p>Here's an example showing how you might rotate an image:</p>
-
-<code>$config['image_library'] = 'netpbm';<br />
-$config['library_path'] = '/usr/bin/';<br />
-$config['source_image']	= '/path/to/image/mypic.jpg';<br />
-$config['rotation_angle'] = 'hor';<br />
-<br />
-$this->image_lib->initialize($config);
-<br />
-<br />
-if ( ! $this->image_lib->rotate())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $this->image_lib->display_errors();<br />
-}</code>
-
-
-
-<h2>$this-&gt;image_lib-&gt;clear()</h2>
-<p>The clear function resets all of the values used when processing an image. You will want to call this if you are processing images in a loop.</p>
-<p><code>$this-&gt;image_lib-&gt;clear();</code></p>
-<p>&nbsp;</p>
-<h1>Image Watermarking</h1>
-
-<p>The Watermarking feature requires the GD/GD2 library.</p>
-
-
-<h2>Two Types of Watermarking</h2>
-
-<p>There are two types of watermarking that you can use:</p>
-
-<ul>
-<li><strong>Text</strong>: The watermark message will be generating using text, either with a True Type font that you specify, or
-using the native text output that the GD library supports. If you use the True Type version your GD installation
-must be compiled with True Type support (most are, but not all).</li>
-
-<li><strong>Overlay</strong>: The watermark message will be generated by overlaying an image (usually a transparent PNG or GIF)
-containing your watermark over the source image.</li>
-
-</ul>
-
-
-<h2>Watermarking an Image</h2>
-
-<p>Just as with the other functions (resizing, cropping, and rotating) the general process for watermarking
-involves setting the preferences corresponding to the action you intend to perform, then
-calling the watermark function.  Here is an example:</p>
-
-<code>
-$config['source_image']	= '/path/to/image/mypic.jpg';<br />
-$config['wm_text'] = 'Copyright 2006 - John Doe';<br />
-$config['wm_type'] = 'text';<br />
-$config['wm_font_path'] = './system/fonts/texb.ttf';<br />
-$config['wm_font_size']	= '16';<br />
-$config['wm_font_color'] = 'ffffff';<br />
-$config['wm_vrt_alignment']  = 'bottom';<br />
-$config['wm_hor_alignment']  = 'center';<br />
-$config['wm_padding']  = '20';<br />
-<br />
-$this->image_lib->initialize($config);
-<br />
-<br />
-$this->image_lib->watermark();</code>
-
-
-<p>The above example will use a 16 pixel True Type font to create the text "Copyright 2006 - John Doe".  The watermark
-will be positioned at the bottom/center of the image, 20 pixels from the bottom of the image.</p>
-
-<p class="important"><strong>Note:</strong> In order for the image class to be allowed to do any processing, the image file must have &quot;write&quot; file permissions. For example, 777.</p>
-
-
-<h2>Watermarking Preferences</h2>

-<h1>Input Class</h1>
-
-<p>The Input Class serves two purposes:</p>
-
-<ol>
-<li>It pre-processes global input data for security.</li>
-<li>It provides some helper functions for fetching input data and pre-processing it.</li>
-</ol>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-
-<h2>Security Filtering</h2>
-
-<p>The security filtering function is called automatically when a new <a href="../general/controllers.html">controller</a> is invoked.  It does the following:</p>
-
-<ul>
-<li>If $config['allow_get_array'] is FALSE(default is TRUE), destroys the global GET array.</li>
-<li>Destroys all global variables in the event register_globals is turned on.</li>
-<li>Filters the GET/POST/COOKIE array keys, permitting only alpha-numeric (and a few other) characters.</li>
-<li>Provides XSS (Cross-site Scripting Hacks) filtering.  This can be enabled globally, or upon request.</li>
-<li>Standardizes newline characters to \n(In Windows \r\n)</li>
-</ul>
-
-
-<h2>XSS Filtering</h2>
-
-<p>The Input class has the ability to filter input automatically to prevent cross-site scripting attacks.  If you want the filter to run automatically every time it encounters POST or COOKIE data you can enable it by opening your
-<kbd>application/config/config.php</kbd> file and setting this:</p>
-
-<code>$config['global_xss_filtering'] = TRUE;</code>
-
-<p>Please refer to the <a href="security.html">Security class</a> documentation for information on using XSS Filtering in your application.</p>
-
-
-<h2>Using POST, COOKIE, or SERVER Data</h2>
-
-<p>CodeIgniter comes with three helper functions that let you fetch POST, COOKIE or SERVER items.  The main advantage of using the provided
-functions rather than fetching an item directly ($_POST['something']) is that the functions will check to see if the item is set and
-return false (boolean) if not.  This lets you conveniently use data without having to test whether an item exists first.
-In other words, normally you might do something like this:</p>
-
-<code>
-if ( ! isset($_POST['something']))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$something = FALSE;<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$something = $_POST['something'];<br />
-}</code>
-
-<p>With CodeIgniter's built in functions you can simply do this:</p>
-
-<code>$something = $this->input->post('something');</code>
-
-<p>The three functions are:</p>
-
-<ul>
-<li>$this->input->post()</li>
-<li>$this->input->cookie()</li>
-<li>$this->input->server()</li>
-</ul>
-
-<h2>$this->input->post()</h2>
-
-<p>The first parameter will contain the name of the POST item you are looking for:</p>
-
-<code>$this->input->post('some_data');</code>
-
-<p>The function returns FALSE (boolean) if the item you are attempting to retrieve does not exist.</p>
-
-<p>The second optional parameter lets you run the data through the XSS filter.  It's enabled by setting the second parameter to boolean TRUE;</p>
-
-<code>$this->input->post('some_data', TRUE);</code>
-
-<p>To return an array of all POST items call without any parameters.</p>
-<p>To return all POST items and pass them through the XSS filter set the first parameter NULL while setting the second parameter to boolean;</p>
-<p>The function returns FALSE (boolean) if there are no items in the POST.</p>
-
-<code>
-	$this->input->post(NULL, TRUE); // returns all POST items with XSS filter
-	<br />
-	$this->input->post(); // returns all POST items without XSS filter
-</code>
-
-<h2>$this->input->get()</h2>
-
-<p>This function is identical to the post function, only it fetches get data:</p>
-
-<code>$this->input->get('some_data', TRUE);</code>
-
-<p>To return an array of all GET items call without any parameters.</p>
-<p>To return all GET items and pass them through the XSS filter set the first parameter NULL while setting the second parameter to boolean;</p>
-<p>The function returns FALSE (boolean) if there are no items in the GET.</p>
-
-<code>
-	$this->input->get(NULL, TRUE); // returns all GET items with XSS filter
-	<br />
-	$this->input->get(); // returns all GET items without XSS filtering
-</code>
-
-<h2>$this->input->get_post()</h2>
-
-<p>This function will search through both the post and get streams for data, looking first in post, and then in get:</p>
-
-<code>$this->input->get_post('some_data', TRUE);</code>
-
-<h2>$this->input->cookie()</h2>
-
-<p>This function is identical to the post function, only it fetches cookie data:</p>
-
-<code>$this->input->cookie('some_data', TRUE);</code>
-
-<h2>$this->input->server()</h2>
-
-<p>This function is identical to the above functions, only it fetches server data:</p>
-
-<code>$this->input->server('some_data');</code>
-
-
-<h2>$this->input->set_cookie()</h2>
-
-<p>Sets a cookie containing the values you specify.  There are two ways to pass information to this function so that a cookie can be set:
-Array Method, and Discrete Parameters:</p>
-
-<h4>Array Method</h4>
-
-<p>Using this method, an associative array is passed to the first parameter:</p>
-
-<code>$cookie = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp;=> 'The Cookie Name',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'value'&nbsp;&nbsp;=> 'The Value',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'expire' => '86500',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'domain' => '.some-domain.com',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'path'&nbsp;&nbsp;&nbsp;=> '/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'prefix' => 'myprefix_',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'secure' => TRUE<br />
-);<br />
-<br />
-$this->input->set_cookie($cookie);
-</code>
-
-<p><strong>Notes:</strong></p>
-
-<p>Only the name and value are required. To delete a cookie set it with the expiration blank.</p>
-
-<p>The expiration is set in <strong>seconds</strong>, which will be added to the current time.  Do not include the time, but rather only the
-number of seconds from <em>now</em> that you wish the cookie to be valid.  If the expiration is set to
-zero the cookie will only last as long as the browser is open.</p>
-<p>For site-wide cookies regardless of how your site is requested, add your URL to the <strong>domain</strong> starting with a period, like this:  .your-domain.com</p>
-<p>The path is usually not needed since the function sets a root path.</p>
-<p>The prefix is only needed if you need to avoid name collisions with other identically named cookies for your server.</p>
-<p>The secure boolean is only needed if you want to make it a secure cookie by setting it to TRUE.</p>
-
-<h4>Discrete Parameters</h4>
-
-<p>If you prefer, you can set the cookie by passing data using individual parameters:</p>
-
-<code>$this->input->set_cookie($name, $value, $expire, $domain, $path, $prefix, $secure);</code>
-
-<h2>$this->input->cookie()</h2>
-
-<p>Lets you fetch a cookie.  The first parameter will contain the name of the cookie you are looking for (including any prefixes):</p>
-
-<code>cookie('some_cookie');</code>
-
-<p>The function returns FALSE (boolean) if the item you are attempting to retrieve does not exist.</p>
-
-<p>The second optional parameter lets you run the data through the XSS filter.  It's enabled by setting the second parameter to boolean TRUE;</p>
-
-<p><code>cookie('some_cookie', TRUE);</code></p>
-
-
-<h2>$this->input->ip_address()</h2>
-<p>Returns the IP address for the current user.  If the IP address is not valid, the function will return an IP of: 0.0.0.0</p>
-<code>echo $this->input->ip_address();</code>
-
-
-<h2>$this->input->valid_ip(<var>$ip</var>)</h2>
-
-<p>Takes an IP address as input and returns TRUE or FALSE (boolean) if it is valid or not.  Note:  The $this->input->ip_address() function above
-validates the IP automatically.</p>
-
-<code>if ( ! $this-&gt;input-&gt;valid_ip($ip))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp; echo 'Not Valid';<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp; echo 'Valid';<br />
-}</code>
-
-
-<h2>$this->input->user_agent()</h2>
-<p>Returns the user agent (web browser) being used by the current user. Returns FALSE if it's not available.</p>
-<code>echo $this->input->user_agent();</code>
-<p>See the <a href="user_agent.html">User Agent Class</a> for methods which extract information from the user agent string.</p>
-
-<h2>$this->input->request_headers()</h2>
-<p>Useful if running in a non-Apache environment where <a href="http://php.net/apache_request_headers">apache_request_headers()</a> will not be supported.  Returns an array of headers.</p>
-
-<code>$headers = $this->input->request_headers();</code>
-
-<h2>$this->input->get_request_header();</h2>
-<p>Returns a single member of the request headers array.</p>
-
-<code>$this->input->get_request_header('some-header', TRUE);</code>
-
-
-<h2>$this->input->is_ajax_request()</h2>
-<p>Checks to see if the <var>HTTP_X_REQUESTED_WITH</var> server header has been set, and returns a boolean response.</p>
-
-
-<h2>$this->input->is_cli_request()</h2>
-<p>Checks to see if the <var>STDIN</var> constant is set, which is a failsafe way to see if PHP is being run on the command line.</p>
-
-<code>$this->input->is_cli_request()</code>

-<h1>Javascript Class</h1>
-<p>CodeIgniter provides a library to help you with certain common functions that you may want to use with Javascript. Please note that CodeIgniter does not require the jQuery library to run, and that any scripting library will work equally well. The jQuery library is simply presented as a convenience if you choose to use it.</p>
-<h2>Initializing the Class</h2>
-<p>To initialize the Javascript class manually in your controller constructor, use the <dfn>$this-&gt;load-&gt;library</dfn> function. Currently, the only available library is jQuery, which will automatically be loaded like this:</p>
-
-<code>$this-&gt;load-&gt;library('javascript');</code>
-
-<p>The Javascript class also accepts parameters, <dfn>js_library_driver (string) default 'jquery'</dfn> and <dfn>autoload (bool) default TRUE</dfn>.  You may override the defaults if you wish by sending an associative array:</p>
-
-<code>$this-&gt;load-&gt;library('javascript', array('js_library_driver' =&gt; 'scripto', 'autoload' =&gt; FALSE));</code>
-
-<p>Again, presently only 'jquery' is available.  You may wish to set <dfn>autoload</dfn> to FALSE, though, if you do not want the jQuery library to automatically include a script tag for the main jQuery script file.  This is useful if you are loading it from a location outside of CodeIgniter, or already have the script tag in your markup.</p>
-
-<p>Once loaded, the jQuery library object will be available using: <dfn>$this-&gt;javascript</dfn></p>
-<h2>Setup and Configuration</h2>
-<h3>Set these variables in your view</h3>
-<p>As a Javascript library, your files must be available to your application.</p>
-<p>As Javascript is a client side language, the library must be able to write content into your final output. This generally means a view. You'll need to include the following variables in the &lt;head&gt; sections of your output.</p>
-<p><code>&lt;?php echo $library_src;?&gt;<br />
-&lt;?php echo $script_head;?&gt;
-</code></p>
-<p>$library_src, is where the actual library file will be loaded, as well as any subsequent plugin script calls; $script_head is where specific events, functions and other commands will be rendered.</p>
-<h3>Set the path to the librarys with config items</h3>
-<p>There are some configuration items in Javascript library. These can either be set in application/config.php, within its own config/javascript.php file, or within any controller usings the set_item() function. </p>
-<p>An image to be used as an &quot;ajax loader&quot;, or progress indicator. Without one, the simple text message of &quot;loading&quot; will appear when Ajax calls need to be made.</p>
-<p><code>$config['javascript_location'] = 'http://localhost/codeigniter/themes/js/jquery/';<br />
-		$config['javascript_ajax_img'] = 'images/ajax-loader.gif';</code></p>
-<p>If you keep your files in the same directories they were downloaded from, then you need not set this configuration items.</p>
-
-<h2>The jQuery Class</h2>
-
-<p>To initialize the jQuery class manually in your controller constructor, use the <dfn>$this-&gt;load-&gt;library</dfn> function:</p>
-
-<code>$this-&gt;load-&gt;library('jquery');</code>
-
-<p>You may send an optional parameter to determine whether or not a script tag for the main jQuery file will be automatically included when loading the library.  It will be created by default.  To prevent this, load the library as follows:</p>
-
-<code>$this-&gt;load-&gt;library('jquery', FALSE);</code>
-
-<p>Once loaded, the jQuery library object will be available using: <dfn>$this-&gt;jquery</dfn></p>
-
-<h2>jQuery Events</h2>
-
-<p>Events are set using the following syntax.</p>
-
-<p><code>$this-&gt;jquery-&gt;event('element_path', code_to_run());</code></p>
-
-<p>In the above example:</p>
-
-<ul>
-	<li>&quot;event&quot; is any of blur, change, click, dblclick, error, focus, hover, keydown, keyup, load, mousedown, mouseup, mouseover, mouseup, resize, scroll, or unload.</li>
-	<li>&quot;element_path&quot; is any valid <a href="http://docs.jquery.com/Selectors">jQuery selector</a>. Due to jQuery's unique selector syntax, this is usually an element id, or CSS selector. For example &quot;#notice_area&quot; would effect &lt;div id=&quot;notice_area&quot;&gt;, and &quot;#content a.notice&quot; would effect all anchors with a class of &quot;notice&quot; in the div with id &quot;content&quot;.</li>
-	<li>&quot;code_to_run()&quot; is script your write yourself, or an action such as an effect from the jQuery library below.</li>
-	</ul>
-
-<h2>Effects</h2>
-
-<p>The query library supports a powerful <a href="http://docs.jquery.com/Effects">Effects</a> repertoire.  Before an effect can be used, it must be loaded:</p>
-
-<p><code>$this->jquery->effect([optional path] plugin name);
-// for example
-$this->jquery->effect('bounce');
-</code></p>
-
-<h3>hide() / show()</h3>
-
-<p>Each of this functions will affect the visibility of an item on your page. hide() will set an item invisible, show() will reveal it.</p>
-<p><code>$this-&gt;jquery-&gt;hide(target,  optional speed, optional extra information);<br />
-	$this-&gt;jquery-&gt;show(target,  optional speed, optional extra information);</code></p>
-
-<ul>
-	<li>&quot;target&quot; will be any valid jQuery selector or selectors.</li>
-	<li>&quot;speed&quot; is optional, and is set to either slow, normal, fast, or alternatively a number of milliseconds.</li>
-	<li>&quot;extra information&quot; is optional, and could include a callback, or other additional information.</li>
-</ul>
-
-<h3>toggle()</h3>
-
-<p>toggle() will change the visibility of an item to the opposite of its current state, hiding visible elements, and revealing hidden ones.</p>
-<p><code>$this-&gt;jquery-&gt;toggle(target);</code></p>
-<ul>
-	<li>&quot;target&quot; will be any valid jQuery selector or selectors.</li>
-</ul>
-
-<h3>animate()</h3>
-
-<p><code> $this-&gt;jquery-&gt;animate(target, parameters, optional speed, optional extra information);</code></p>
-<ul>
-	<li>&quot;target&quot; will be any valid jQuery selector or selectors.</li>
-	<li>&quot;parameters&quot; in jQuery would generally include a series of CSS properties that you wish to change.</li>
-	<li>&quot;speed&quot; is optional, and is set to either slow, normal, fast, or alternatively a number of milliseconds.</li>
-	<li>&quot;extra information&quot; is optional, and could include a callback, or other additional information.</li>
-</ul>
-<p>For a full summary, see <a href="http://docs.jquery.com/Effects/animate">http://docs.jquery.com/Effects/animate</a></p>
-<p>Here is an example of an animate() called on a div with an id of &quot;note&quot;, and triggered by a click using the jQuery library's click() event.</p>
-<p><code> $params = array(<br />
-	'height' =&gt; 80,<br />
-	'width' =&gt; '50%',<br />
-	'marginLeft' =&gt; 125<br />
-);<br />
-$this-&gt;jquery-&gt;click('#trigger', $this-&gt;jquery-&gt;animate('#note', $params, normal));</code></p>
-
-<h3>fadeIn() / fadeOut()</h3>
-
-<p><code>$this-&gt;jquery-&gt;fadeIn(target,  optional speed, optional extra information);<br />
-	$this-&gt;jquery-&gt;fadeOut(target,  optional speed, optional extra information);</code></p>
-<ul>
-	<li>&quot;target&quot; will be any valid jQuery selector or selectors.</li>
-	<li>&quot;speed&quot; is optional, and is set to either slow, normal, fast, or alternatively a number of milliseconds.</li>
-	<li>&quot;extra information&quot; is optional, and could include a callback, or other additional information.</li>
-</ul>
-
-<h3>toggleClass()</h3>
-
-<p>This function will add or remove a CSS class to its target.</p>
-<p><code>$this-&gt;jquery-&gt;toggleClass(target, class)</code></p>
-<ul>
-	<li>&quot;target&quot; will be any valid jQuery selector or selectors.</li>
-	<li>&quot;class&quot; is any CSS classname. Note that this class must be defined and available in a CSS that is already loaded.</li>
-	</ul>
-
-<h3>fadeIn() / fadeOut()</h3>
-
-<p>These effects cause an element(s) to disappear or reappear over time.</p>
-<p><code>$this-&gt;jquery-&gt;fadeIn(target,  optional speed, optional extra information);<br />
-	$this-&gt;jquery-&gt;fadeOut(target,  optional speed, optional extra information);</code></p>
-<ul>
-	<li>&quot;target&quot; will be any valid jQuery selector or selectors.</li>
-	<li>&quot;speed&quot; is optional, and is set to either slow, normal, fast, or alternatively a number of milliseconds.</li>
-	<li>&quot;extra information&quot; is optional, and could include a callback, or other additional information.</li>
-</ul>
-
-<h3>slideUp() / slideDown() / slideToggle()</h3>
-
-<p>These effects cause an element(s) to slide.</p>
-<p><code>$this-&gt;jquery-&gt;slideUp(target,  optional speed, optional extra information);<br />
-	$this-&gt;jquery-&gt;slideDown(target,  optional speed, optional extra information);<br />
-$this-&gt;jquery-&gt;slideToggle(target,  optional speed, optional extra information);</code></p>
-<ul>
-	<li>&quot;target&quot; will be any valid jQuery selector or selectors.</li>
-	<li>&quot;speed&quot; is optional, and is set to either slow, normal, fast, or alternatively a number of milliseconds.</li>
-	<li>&quot;extra information&quot; is optional, and could include a callback, or other additional information.</li>
-</ul>
-
-<h2>Plugins</h2>
-
-<p>
-
-<p>Some select jQuery plugins are made available using this library.</p>

-<h1>Language Class</h1>
-
-<p>The Language Class provides functions to retrieve language files and lines of text for purposes of internationalization.</p>
-
-<p>In your CodeIgniter system folder you'll find one called <dfn>language</dfn> containing sets of language files.  You can create
-your own language files as needed in order to display error and other messages in other languages.</p>
-
-<p>Language files are typically stored in your <dfn>system/language</dfn> directory.  Alternately you can create a folder called <kbd>language</kbd> inside
-your <kbd>application</kbd> folder and store them there.  CodeIgniter will look first in your <dfn>application/language</dfn>
-directory.  If the directory does not exist or the specified language is not located there CI will instead look in your global
-<dfn>system/language</dfn> folder.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; Each language should be stored in its own folder.  For example, the English files are located at:
-<dfn>system/language/english</dfn></p>
-
-
-
-<h2>Creating Language Files</h2>
-
-<p>Language files must be named with <kbd>_lang.php</kbd> as the file extension.  For example, let's say you want to create a file
-containing error messages.  You might name it:  <kbd>error_lang.php</kbd></p>
-
-<p>Within the file you will assign each line of text to an array called <var>$lang</var> with this prototype:</p>
-
-<code>$lang['language_key'] = "The actual message to be shown";</code>
-
-<p><strong>Note:</strong> It's a good practice to use a common prefix for all messages in a given file to avoid collisions with
-similarly named items in other files.  For example, if you are creating error messages you might prefix them with <var>error_</var></p>
-
-<code>$lang['<var>error</var>_email_missing'] = "You must submit an email address";<br />
-$lang['<var>error</var>_url_missing'] = "You must submit a URL";<br />
-$lang['<var>error</var>_username_missing'] = "You must submit a username";</code>
-
-
-<h2>Loading A Language File</h2>
-
-<p>In order to fetch a line from a particular file you must load the file first.  Loading a language file is done with the following code:</p>
-
-<code>$this->lang->load('<samp>filename</samp>', '<dfn>language</dfn>');</code>
-
-<p>Where <samp>filename</samp> is the name of the file you wish to load (without the file extension), and <dfn>language</dfn>
-is the language set containing it (ie, english).  If the second parameter is missing, the default language set in your
-<kbd>application/config/config.php</kbd> file will be used.</p>
-
-
-<h2>Fetching a Line of Text</h2>
-
-<p>Once your desired language file is loaded you can access any line of text using this function:</p>
-
-<code>$this->lang->line('<samp>language_key</samp>');</code>
-
-<p>Where <samp>language_key</samp> is the array key corresponding to the line you wish to show.</p>
-
-<p>Note: This function simply returns the line.  It does not echo it for you.</p>
-
-<h3>Using language lines as form labels</h3>
-
-<p class="important">This feature has been deprecated from the language library and moved to the <kbd>lang()</kbd> function of the <a href="../helpers/language_helper.html">Language helper</a>.</p>
-
-<h2>Auto-loading Languages</h2>
-<p>If you find that you need a particular language globally throughout your application, you can tell CodeIgniter to <a href="../general/autoloader.html">auto-load</a> it during system initialization. This is done by opening the application/config/autoload.php file and adding the language(s) to the autoload array.</p>

-<h1>Loader Class</h1>
-
-<p>Loader, as the name suggests, is used to load elements.  These elements can be libraries (classes) <a href="../general/views.html">View files</a>,
-<a href="../general/helpers.html">Helpers</a>, <a href="../general/models.html">Models</a>, or your own files.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-<p>The following functions are available in this class:</p>
-
-
-<h2>$this->load->library('<var>class_name</var>', <samp>$config</samp>, <kbd>'object name'</kbd>)</h2>
-
-
-<p>This function is used to load core classes.  Where <var>class_name</var> is the name of the class you want to load.
-Note: We use the terms "class" and "library" interchangeably.</p>
-
-<p>For example, if you would like to send email with CodeIgniter, the first step is to load the email class within your controller:</p>
-
-<code>$this->load->library('email');</code>
-
-<p>Once loaded, the library will be ready for use, using <kbd>$this->email-></kbd><samp><em>some_function</em>()</samp>.</p>
-
-<p>Library files can be stored in subdirectories within the main "libraries" folder, or within your personal <dfn>application/libraries</dfn> folder.
-To load a file located in a subdirectory, simply include the path, relative to the "libraries" folder.
-For example, if you have file located at:</p>
-
-<code>libraries/flavors/chocolate.php</code>
-
-<p>You will load it using:</p>
-
-<code>$this->load->library('flavors/chocolate');</code>
-
-<p>You may nest the file in as many subdirectories as you want.</p>
-
-<p>Additionally, multiple libraries can be loaded at the same time by passing an array of libraries to the load function.</p>
-
-<code>$this->load->library(array('<var>email</var>', '<var>table</var>'));</code>
-
-<h3>Setting options</h3>
-
-<p>The second (optional) parameter allows you to optionally pass configuration setting.  You will typically pass these as an array:</p>
-
-<code>
-$config = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'mailtype' => 'html',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'charset'&nbsp; => 'utf-8,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'priority' => '1'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->load->library('email', $config);</code>
-
-<p>Config options can usually also be set via a config file. Each library is explained in detail in its own page, so please read the information regarding each one you would like to use.</p>
-
-<p>Please take note, when multiple libraries are supplied in an array for the first parameter, each will receive the same parameter information.</p>
-
-<h3>Assigning a Library to a different object name</h3>
-
-<p>If the third (optional) parameter is blank, the library will usually be assigned to an object with the same name as the library.  For example, if the library is named <dfn>Session</dfn>, it
-will be assigned to a variable named <dfn>$this->session</dfn>.</p>
-
-<p>If you prefer to set your own class names you can pass its value to the third parameter:</p>
-
-<code>$this->load->library('session', '', 'my_session');<br /><br />
-
-// Session class is now accessed using:<br /><br />
-
-$this->my_session
-
-</code>
-
-<p>Please take note, when multiple libraries are supplied in an array for the first parameter, this parameter is discarded.</p>
-
-
-<h2>$this->load->view('<var>file_name</var>', <samp>$data</samp>, <kbd>true/false</kbd>)</h2>
-
-<p>This function is used to load your View files.  If you haven't read the <a href="../general/views.html">Views</a> section of the
-user guide it is recommended that you do since it shows you how this function is typically used.</p>
-
-<p>The first parameter is required.  It is the name of the view file you would like to load. &nbsp;Note: The .php file extension does not need to be specified unless you use something other than <kbd>.php</kbd>.</p>
-
-<p>The second <strong>optional</strong> parameter can take
-an associative array or an object as input, which it runs through the PHP <a href="http://www.php.net/extract">extract</a> function to
-convert to variables that can be used in your view files.  Again, read the <a href="../general/views.html">Views</a> page to learn
-how this might be useful.</p>
-
-<p>The third <strong>optional</strong> parameter lets you change the behavior of the function so that it returns data as a string
-rather than sending it to your browser.  This can be useful if you want to process the data in some way.  If you
-set the parameter to <kbd>true</kbd> (boolean) it will return data.  The default behavior is <kbd>false</kbd>, which sends it
-to your browser.  Remember to assign it to a variable if you want the data returned:</p>
-
-<code>$string = $this->load->view('<var>myfile</var>', '', <kbd>true</kbd>);</code>
-
-
-<h2>$this-&gt;load-&gt;model('<var>Model_name</var>');</h2>
-<p><code>$this-&gt;load-&gt;model('<var>Model_name</var>');</code></p>
-<p>If your model is located in a sub-folder, include the relative path from your models folder. For example, if you have a model located at application/models/blog/queries.php you'll load it using:</p>
-<p><code>$this-&gt;load-&gt;model('<var>blog/queries</var>');</code></p>
-<p>If you would like your model assigned to a different object name you can specify it via the second parameter of the loading
-	function:</p>
-<code> $this-&gt;load-&gt;model('<var>Model_name</var>', '<kbd>fubar</kbd>');<br />
-<br />
-$this-&gt;<kbd>fubar</kbd>-&gt;function();</code>
-<h2>$this->load->database('<var>options</var>', <kbd>true/false</kbd>)</h2>
-<p>This function lets you load the database class.  The two parameters are <strong>optional</strong>.  Please see the
-<a href="../database/index.html">database</a> section for more info.</p>
-
-
-
-
-<h2>$this->load->vars(<samp>$array</samp>)</h2>
-
-<p>This function takes an associative array as input and generates variables using the PHP <a href="http://www.php.net/extract">extract</a> function.
-This function produces the same result as using the second parameter of the <dfn>$this->load->view()</dfn> function above.  The reason you might
-want to use this function independently is if you would like to set some global variables in the constructor of your controller
-and have them become available in any view file loaded from any function.  You can have multiple calls to this function.  The data get cached
-and merged into one array for conversion to variables.
-</p>
-
-
-<h2>$this->load->get_var(<samp>$key</samp>)</h2>
-
-<p>This function checks the associative array of variables available to your views. This is useful if for any reason a var is set in a library or another controller method using $this->load->vars().
-</p>
-
-
-<h2>$this->load->helper('<var>file_name</var>')</h2>
-<p>This function loads helper files, where <var>file_name</var> is the name of the file, without the <kbd>_helper.php</kbd> extension.</p>
-
-
-<h2>$this->load->file('<var>filepath/filename</var>', <kbd>true/false</kbd>)</h2>
-<p>This is a generic file loading function.  Supply the filepath and name in the first parameter and it will open and read the file.
-By default the data is sent to your browser, just like a View file, but if you set the second parameter to <kbd>true</kbd> (boolean)
-it will instead return the data as a string.</p>
-

-<h2>$this->load->language('<var>file_name</var>')</h2>
-<p>This function is an alias of the <a href="language.html">language loading function</a>: $this->lang->load()</p>
-
-<h2>$this->load->config('<var>file_name</var>')</h2>
-<p>This function is an alias of the <a href="config.html">config file loading function</a>: $this->config->load()</p>

-<h2>Application "Packages"</h2>
-
-<p>An application package allows for the easy distribution of complete sets of resources in a single directory, complete with its own libraries, models, helpers, config, and language files.  It is recommended that these packages be placed in the <dfn>application/third_party</dfn> folder.  Below is a sample map of an package directory</p>
-
-
-<h2>Sample Package "Foo Bar" Directory Map</h2>
-
-<p>The following is an example of a directory for an application package named "Foo Bar".</p>
-
-<code>/application/third_party/foo_bar<br />
-<br />
-config/<br />
-helpers/<br />
-language/<br />
-libraries/<br />
-models/<br />
-</code>
-
-<p>Whatever the purpose of the "Foo Bar" application package, it has its own config files, helpers, language files, libraries, and models.  To use these resources in your controllers, you first need to tell the Loader that you are going to be loading resources from a package, by adding the package path.</p>
-
-<h3>$this->load->add_package_path()</h3>
-
-<p>Adding a package path instructs the Loader class to prepend a given path for subsequent requests for resources.  As an example, the "Foo Bar" application package above has a library named <dfn>Foo_bar.php</dfn>. In our controller, we'd do the following:</p>
-
-<code>$this->load->add_package_path(<var>APPPATH</var>.'third_party/<var>foo_bar</var>/');<br />
-$this->load->library('foo_bar');</code>
-
-<h3>$this->load->remove_package_path()</h3>
-
-<p>When your controller is finished using resources from an application package, and particularly if you have other application packages you want to work with, you may wish to remove the package path so the Loader no longer looks in that folder for resources.  To remove the last path added, simply call the method with no parameters.</p>
-
-<h3>$this->load->remove_package_path()</h3>
-
-<p>Or to remove a specific package path, specify the same path previously given to <kbd>add_package_path() for a package.</kbd>:</p>
-
-<code>$this->load->remove_package_path(<var>APPPATH</var>.'third_party/<var>foo_bar</var>/');</code>
-
-<h3>Package view files</h3>
-
-<p>By Default, package view files paths are set when <samp>add_package_path()</samp> is called.  View paths are looped through, and once a match is encountered that view is loaded.</p>
-<p>In this instance, it is possible for view naming collisions within packages to occur, and possibly the incorrect package being loaded.  To ensure against this, set an optional second parameter of <var>FALSE</var> when calling <samp>add_package_path()</samp>.</p>
-
-<code>
-$this->load->add_package_path(APPPATH.'my_app', FALSE);<br>
-$this->load->view('my_app_index'); // Loads<br>
-$this->load->view('welcome_message'); // Will not load the default welcome_message b/c the second param to add_package_path is FALSE<br>
-<br>
-// Reset things<br>
-$this->load->remove_package_path(APPPATH.'my_app');<br>
-<br>
-// Again without the second parameter:<br>
-$this->load->add_package_path(APPPATH.'my_app', TRUE);<br>
-$this->load->view('my_app_index'); // Loads<br>
-$this->load->view('welcome_message'); // Loads<br>
-</code>

-<h1>Output Class</h1>
-
-<p>The Output class is a small class with one main function:  To send the finalized web page to the requesting browser.  It is
-also responsible for <a href="../general/caching.html">caching</a> your web pages, if you use that feature.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-<p>Under normal circumstances you won't even notice the Output class since it works transparently without your intervention.
-For example, when you use the <a href="../libraries/loader.html">Loader</a> class to load a view file, it's automatically
-passed to the Output class, which will be called automatically by CodeIgniter at the end of system execution.
-It is possible, however, for you to manually intervene with the output if you need to, using either of the two following functions:</p>
-
-<h2>$this->output->set_output();</h2>
-
-<p>Permits you to manually set the final output string.  Usage example:</p>
-
-<code>$this->output->set_output($data);</code>
-
-<p><strong>Important:</strong> If you do set your output manually, it must be the last thing done in the function you call it from.
-For example, if you build a page in one of your controller functions, don't set the output until the end.</p>
-
-
-<h2>$this->output->set_content_type();</h2>
-
-<p>Permits you to set the mime-type of your page so you can serve JSON data, JPEG's, XML, etc easily.</p>
-
-<code>$this->output<br />
-&nbsp;&nbsp;&nbsp;&nbsp;->set_content_type('application/json')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;->set_output(json_encode(array('foo' => 'bar')));<br />
-<br />
-$this->output<br />
-&nbsp;&nbsp;&nbsp;&nbsp;->set_content_type('jpeg') // You could also use ".jpeg" which will have the full stop removed before looking in config/mimes.php<br />
-&nbsp;&nbsp;&nbsp;&nbsp;->set_output(file_get_contents('files/something.jpg'));</code>
-
-<p><strong>Important:</strong> Make sure any non-mime string you pass to this method exists in config/mimes.php or it will have no effect.</p>
-
-
-<h2>$this->output->get_output();</h2>
-
-<p>Permits you to manually retrieve any output that has been sent for storage in the output class.  Usage example:</p>
-<code>$string = $this->output->get_output();</code>
-
-<p>Note that data will only be retrievable from this function if it has been previously sent to the output class by one of the
-CodeIgniter functions like <var>$this->load->view()</var>.</p>
-
-
-<h2>$this->output->append_output();</h2>
-
-<p>Appends data onto the output string.  Usage example:</p>
-
-<code>$this->output->append_output($data);</code>
-
-
-
-<h2>$this->output->set_header();</h2>
-
-<p>Permits you to manually set server headers, which the output class will send for you when outputting the final rendered display.  Example:</p>
-
-<code>
-$this->output->set_header("HTTP/1.0 200 OK");<br />
-$this->output->set_header("HTTP/1.1 200 OK");<br />
-$this->output->set_header('Last-Modified: '.gmdate('D, d M Y H:i:s', $last_update).' GMT');<br />
-$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate");<br />
-$this->output->set_header("Cache-Control: post-check=0, pre-check=0");<br />
-$this->output->set_header("Pragma: no-cache");	</code>
-
-
-<h2>$this->output->set_status_header(<var>code</var>, '<var>text</var>');</h2>
-
-<p>Permits you to manually set a server status header.  Example:</p>
-
-<code>$this->output->set_status_header('401');<br />
-// Sets the header as:  Unauthorized</code>
-
-<p><a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html">See here</a> for a full list of headers.</p>
-
-<h2>$this->output->enable_profiler();</h2>
-
-<p>Permits you to enable/disable the <a href="../general/profiling.html">Profiler</a>, which will display benchmark and other data
-at the bottom of your pages for debugging and optimization purposes.</p>
-
-<p>To enable the profiler place the following function anywhere within your <a href="../general/controllers.html">Controller</a> functions:</p>
-<code>$this->output->enable_profiler(TRUE);</code>
-
-<p>When enabled a report will be generated and inserted at the bottom of your pages.</p>
-
-<p>To disable the profiler you will use:</p>
-<code>$this->output->enable_profiler(FALSE);</code>
-
-<h2>$this->output->set_profiler_sections();</h2>
-
-<p>Permits you to enable/disable specific sections of the Profiler when enabled.  Please refer to the <a href="../general/profiling.html">Profiler</a> documentation for further information.</p>
-
-<h2>$this->output->cache();</h2>
-<p>The CodeIgniter output library also controls caching.  For more information, please see the <a href="../general/caching.html">caching documentation</a>.</p>
-
-<h2>Parsing Execution Variables</h2>
-
-	<p>CodeIgniter will parse the pseudo-variables <var>{elapsed_time}</var> and <var>{memory_usage}</var> in your output by default.  To disable this, set the <var>$parse_exec_vars</var> class property to <var>FALSE</var> in your controller.
-
-	<code>$this->output->parse_exec_vars = FALSE;</code>

-<h1>Pagination Class</h1>
-
-<p>CodeIgniter's Pagination class is very easy to use, and it is 100% customizable, either dynamically or via stored preferences.</p>
-
-<p>If you are not familiar with the term "pagination", it refers to links that allows you to navigate from page to page, like this:</p>
-
-<code><a href="#">&laquo; First</a>&nbsp;&nbsp;<a href="#">&lt;</a>&nbsp;<a href="#">1</a>&nbsp;<a href="#">2</a>&nbsp;<b>3</b>&nbsp;<a href="#">4</a>&nbsp;<a href="#">5</a>&nbsp;<a href="#">&gt;</a>&nbsp;&nbsp;<a href="#">Last &raquo;</a></code>
-
-<h2>Example</h2>
-
-<p>Here is a simple example showing how to create pagination in one of your <a href="../general/controllers.html">controller</a> functions:</p>
-
-<code>
-$this->load->library('pagination');<br /><br />
-$config['base_url'] = 'http://example.com/index.php/test/page/';<br />
-$config['total_rows'] = 200;<br />
-$config['per_page']  = 20;
-<br /><br />
-$this->pagination->initialize($config);
-
-<br /><br />
-echo  $this->pagination->create_links();</code>
-
-<h3>Notes:</h3>
-
-<p>The <var>$config</var> array contains your configuration variables.  It is passed to the <dfn>$this->pagination->initialize</dfn> function as shown above.  Although there are some twenty items you can configure, at
-minimum you need the three shown.  Here is a description of what those items represent:</p>
-
-<ul>
-	<li><strong>base_url</strong> This is the full URL to the controller class/function containing your pagination.  In the example
-	above, it is pointing to a controller called "Test" and a function called "page".  Keep in mind that you can
-	<a href="../general/routing.html">re-route your URI</a> if you need a different structure.</li>
-	<li><strong>total_rows</strong> This number represents the total rows in the result set you are creating pagination for.
-	Typically this number will be the total rows that your database query returned.
-	</li>
-	<li><strong>per_page</strong> The number of items you intend to show per page.  In the above example, you would be showing 20 items per page.</li>
-</ul>
-
-<p>The <var>create_links()</var> function returns an empty string when there is no pagination to show.</p>
-
-
-<h3>Setting preferences in a config file</h3>
-
-<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
-Simply create a new file called <var>pagination.php</var>,  add the <var>$config</var>
-array in that file. Then save the file in: <var>config/pagination.php</var> and it will be used automatically. You
-will NOT need to use the <dfn>$this->pagination->initialize</dfn> function if you save your preferences in a config file.</p>
-
-
-<h2>Customizing the Pagination</h2>
-
-<p>The following is a list of all the preferences you can pass to the initialization function to tailor the display.</p>
-
-
-<h4>$config['uri_segment'] = 3;</h4>
-
-<p>The pagination function automatically determines which segment of your URI contains the page number. If you need
-something different you can specify it.</p>
-
-<h4>$config['num_links'] = 2;</h4>
-
-<p>The number of &quot;digit&quot; links you would like before and after the selected page number. For example, the number 2
-	will place two digits on either side, as in the example links at the very top of this page.</p>
-
-<h4>$config['use_page_numbers'] = TRUE;</h4>
-<p>By default, the URI segment will use the starting index for the items you are paginating. If you prefer to show the the actual page number, set this to TRUE.</p>
-
-<h4>$config['page_query_string'] = TRUE;</h4>
-<p>By default, the pagination library assume you are using <a href="../general/urls.html">URI Segments</a>, and constructs your links something like</p>
-<p><code>http://example.com/index.php/test/page/20</code></p>
-<p>If you have $config['enable_query_strings']  set to TRUE your links will automatically be re-written using Query Strings. This option can also be explictly set. Using $config['page_query_string'] set to TRUE, the pagination link will become.</p>
-<p><code>http://example.com/index.php?c=test&amp;m=page&amp;per_page=20</code></p>
-<p>Note that &quot;per_page&quot; is the default query string  passed, however can be configured using $config['query_string_segment'] = 'your_string'</p>
-<h2>Adding Enclosing Markup</h2>
-
-<p>If you would like to surround the entire pagination with some markup you can do it with these two prefs:</p>
-
-<h4>$config['full_tag_open'] = '&lt;p>';</h4>
-<p>The opening tag placed on the left side of the entire result.</p>
-
-<h4>$config['full_tag_close'] = '&lt;/p>';</h4>
-<p>The closing tag placed on the right side of the entire result.</p>
-
-
-<h2>Customizing the First Link</h2>
-
-<h4>$config['first_link'] = 'First';</h4>
-<p>The text you would like shown in the "first" link on the left. If you do not want this link rendered, you can set its value to FALSE.</p>
-
-<h4>$config['first_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "first" link.</p>
-
-<h4>$config['first_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "first" link.</p>
-
-<h2>Customizing the Last Link</h2>
-
-<h4>$config['last_link'] = 'Last';</h4>
-<p>The text you would like shown in the "last" link on the right. If you do not want this link rendered, you can set its value to FALSE.</p>
-
-<h4>$config['last_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "last" link.</p>
-
-<h4>$config['last_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "last" link.</p>
-
-<h2>Customizing the "Next" Link</h2>
-
-<h4>$config['next_link'] = '&amp;gt;';</h4>
-<p>The text you would like shown in the "next" page link. If you do not want this link rendered, you can set its value to FALSE.</p>
-
-<h4>$config['next_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "next" link.</p>
-
-<h4>$config['next_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "next" link.</p>
-
-<h2>Customizing the "Previous" Link</h2>
-
-<h4>$config['prev_link'] = '&amp;lt;';</h4>
-<p>The text you would like shown in the "previous" page link. If you do not want this link rendered, you can set its value to FALSE.</p>
-
-<h4>$config['prev_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "previous" link.</p>
-
-<h4>$config['prev_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "previous" link.</p>
-
-<h2>Customizing the "Current Page" Link</h2>
-
-<h4>$config['cur_tag_open'] = '&lt;b>';</h4>
-<p>The opening tag for the "current" link.</p>
-
-<h4>$config['cur_tag_close'] = '&lt;/b>';</h4>
-<p>The closing tag for the "current" link.</p>
-
-
-<h2>Customizing the "Digit" Link</h2>
-
-<h4>$config['num_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "digit" link.</p>
-
-<h4>$config['num_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "digit" link.</p>
-
-<h2>Hiding the Pages</h2>
-
-<p>If you wanted to not list the specific pages (for example, you only want "next" and "previous" links), you can suppress their rendering by adding:</p>
-
-<code>
-$config['display_pages'] = FALSE;
-</code>
-
-
-<h2>Adding a class to every anchor</h2>
-
-<p>If you want to add a class attribute to every link rendered by the pagination class, you can set the config "anchor_class" equal to the classname you want.</p>

-<h1>Template Parser Class</h1>
-
-<p>The Template Parser Class enables you to parse pseudo-variables contained within your view files. It can parse simple
-variables or variable tag pairs. If you've never used a template engine, pseudo-variables look like this:</p>
-
-<code>&lt;html&gt;<br />
-&lt;head&gt;<br />
-&lt;title&gt;<kbd>{blog_title}</kbd>&lt;/title&gt;<br />
-&lt;/head&gt;<br />
-&lt;body&gt;<br />
-<br />
-&lt;h3&gt;<kbd>{blog_heading}</kbd>&lt;/h3&gt;<br />
-<br />
-<kbd>{blog_entries}</kbd><br />
-&lt;h5&gt;<kbd>{title}</kbd>&lt;/h5&gt;<br />
-&lt;p&gt;<kbd>{body}</kbd>&lt;/p&gt;<br />
-<kbd>{/blog_entries}</kbd><br />
-
-&lt;/body&gt;<br />
-&lt;/html&gt;</code>
-
-<p>These variables are not actual PHP variables, but rather plain text representations that allow you to eliminate
-PHP from your templates (view files).</p>
-
-<p class="important"><strong>Note:</strong> CodeIgniter does <strong>not</strong> require you to use this class
-since using pure PHP in your view pages lets them run a little faster.  However, some developers prefer to use a template engine if
-they work with designers who they feel would find some confusion working with PHP.</p>
-
-<p><strong>Also Note:</strong> The Template Parser Class is <strong>not</strong>  a
-full-blown template parsing solution. We've kept it very lean on purpose in order to maintain maximum performance.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Parser class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('parser');</code>
-<p>Once loaded, the Parser library object will be available using: <dfn>$this->parser</dfn></p>
-
-
-<p>The following functions are available in this library:</p>
-
-<h2>$this->parser->parse()</h2>
-
-<p>This method accepts a template name and data array as input, and it generates a parsed version.  Example:</p>
-
-<code>$this->load->library('parser');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_title' => 'My Blog Title',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_heading' => 'My Blog Heading'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->parser->parse('blog_template', $data);</code>
-
-<p>The first parameter contains the name of the <a href="../general/views.html">view file</a> (in this example the file would be called blog_template.php),
-and the second parameter contains an associative array of data to be replaced in the template.  In the above example, the
-template would contain two variables: {blog_title} and {blog_heading}</p>
-
-<p>There is no need to "echo" or do something with the data returned by <dfn>$this->parser->parse()</dfn>.  It is automatically
-passed to the output class to be sent to the browser.  However, if you do want the data returned instead of sent to the output class you can
-pass TRUE (boolean) to the third parameter:</p>
-
-<code>$string = $this->parser->parse('blog_template', $data, TRUE);</code>
-
-<h2>$this->parser->parse_string()</h2>
-
-<p>This method works exactly like parse(), only accepts a string as the first parameter in place of a view file.</p>
-
-
-<h2>Variable Pairs</h2>
-
-<p>The above example code allows simple variables to be replaced.  What if you would like an entire block of variables to be
-repeated, with each iteration containing new values?  Consider the template example we showed at the top of the page:</p>
-
-<code>&lt;html&gt;<br />
-&lt;head&gt;<br />
-&lt;title&gt;<kbd>{blog_title}</kbd>&lt;/title&gt;<br />
-&lt;/head&gt;<br />
-&lt;body&gt;<br />
-<br />
-&lt;h3&gt;<kbd>{blog_heading}</kbd>&lt;/h3&gt;<br />
-<br />
-<kbd>{blog_entries}</kbd><br />
-&lt;h5&gt;<kbd>{title}</kbd>&lt;/h5&gt;<br />
-&lt;p&gt;<kbd>{body}</kbd>&lt;/p&gt;<br />
-<kbd>{/blog_entries}</kbd><br />
-
-&lt;/body&gt;<br />
-&lt;/html&gt;</code>
-
-<p>In the above code you'll notice a pair of variables: <kbd>{blog_entries}</kbd> data... <kbd>{/blog_entries}</kbd>.
-In a case like this, the entire chunk of data between these pairs would be repeated multiple times, corresponding
-to the number of rows in a result.</p>
-
-<p>Parsing variable pairs is done using the identical code shown above to parse single variables,
-except, you will add a multi-dimensional array corresponding to your variable pair data.
-Consider this example:</p>
-
-
-<code>$this->load->library('parser');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_title'&nbsp;&nbsp; => 'My Blog Title',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_heading' => 'My Blog Heading',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_entries' => array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 1', 'body' => 'Body 1'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 2', 'body' => 'Body 2'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 3', 'body' => 'Body 3'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 4', 'body' => 'Body 4'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 5', 'body' => 'Body 5')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->parser->parse('blog_template', $data);</code>
-
-<p>If your "pair" data is coming from a database result, which is already a multi-dimensional array, you can simply
-use the database result_array() function:</p>
-
-<code>
-$query = $this->db->query("SELECT * FROM blog");<br />
-<br />
-$this->load->library('parser');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_title'&nbsp;&nbsp; => 'My Blog Title',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_heading' => 'My Blog Heading',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_entries' => $query->result_array()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->parser->parse('blog_template', $data);</code>

-<h1>Security Class</h1>
-
-<p>The Security Class contains methods that help you create a secure application, processing input data for security.</p>
-
-<h2>XSS Filtering</h2>
-
-<p>CodeIgniter comes with a Cross Site Scripting Hack prevention filter which can either run automatically to filter
-all POST and COOKIE data that is encountered, or you can run it on a per item basis.  By default it does <strong>not</strong>
-run globally since it requires a bit of processing overhead, and since you may not need it in all cases.</p>
-
-<p>The XSS filter looks for commonly used techniques to trigger Javascript or other types of code that attempt to hijack cookies
-or do other malicious things.  If anything disallowed is encountered it is rendered safe by converting the data to character entities.</p>
-
-<p>
-Note: This function should only be used to deal with data upon submission. It's not something that should be used for general runtime processing since it requires a fair amount of processing overhead.</p>
-
-
-<p>To filter data through the XSS filter use this function:</p>
-
-<h2>$this->security->xss_clean()</h2>
-
-<p>Here is an usage example:</p>
-
-<code>$data = $this->security->xss_clean($data);</code>
-
-<p>If you want the filter to run automatically every time it encounters POST or COOKIE data you can enable it by opening your
-<kbd>application/config/config.php</kbd> file and setting this:</p>
-
-<code>$config['global_xss_filtering'] = TRUE;</code>
-
-<p>Note: If you use the form validation class, it gives you the option of XSS filtering as well.</p>
-
-<p>An optional second parameter, <dfn>is_image</dfn>, allows this function to be used to test images for potential XSS attacks, useful for file upload security.  When this second parameter is set to <dfn>TRUE</dfn>, instead of returning an altered string, the function returns TRUE if the image is safe, and FALSE if it contained potentially malicious information that a browser may attempt to execute.</p>
-
-<code>if ($this->security->xss_clean($file, TRUE) === FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;// file failed the XSS test<br />
-}</code>
-
-
-<h2>$this->security->sanitize_filename()</h2>
-
-<p>When accepting filenames from user input, it is best to sanitize them to prevent directory traversal and other security related issues.  To do so, use the <dfn>sanitize_filename()</dfn> method of the Security class.  Here is an example:</p>
-
-<code>$filename = $this->security->sanitize_filename($this->input->post('filename'));</code>
-
-<p>If it is acceptable for the user input to include relative paths, e.g. <kbd>file/in/some/approved/folder.txt</kbd>, you can set the second optional parameter,
-	<samp>$relative_path</samp> to TRUE.</p>
-
-<code>$filename = $this->security->sanitize_filename($this->input->post('filename'), TRUE);</code>
-
-<!-- @todo write docs for CSRF methods -->
-
-<h2>Cross-site request forgery (CSRF)</h2>
-
-<p>You can enable csrf protection by opening your <kbd>application/config/config.php</kbd> file and setting this:</p>
-<code>$config['csrf_protection'] = TRUE;</code>
-
-<p>If you use the <a href="../helpers/form_helper.html">form helper</a> the <var>form_open()</var> function will automatically insert a hidden csrf field in your forms.</p>
-
-<p>Select URIs can be whitelisted from csrf protection (for example API endpoints expecting externally POSTed content). You can add these URIs by editing the 'csrf_exclude_uris' config parameter:</p>
-<code>$config['csrf_exclude_uris'] = array('api/person/add');</code>

-<h1>Session Class</h1>
-
-<p>The Session class permits you maintain a user's "state" and track their activity while they browse your site.
-The Session class stores session information for each user as serialized (and optionally encrypted) data in a cookie.
-It can also store the session data in a database table for added security, as this permits the session ID in the
-user's cookie to be matched against the stored session ID. By default only the cookie is saved.  If you choose to
-use the database option you'll need to create the session table as indicated below.
-</p>
-
-<p class="important"><strong>Note:</strong> The Session class does <strong>not</strong> utilize native PHP sessions. It
-generates its own session data, offering more flexibility for developers.</p>
-
-<p class="important"><strong>Note:</strong> Even if you are not using encrypted sessions, you must set
-an <a href="./encryption.html">encryption key</a> in your config file which is used to aid in preventing session data manipulation.</p>
-
-<h2>Initializing a Session</h2>
-
-<p>Sessions will typically run globally with each page load, so the session class must either be
-<a href="../general/libraries.html">initialized</a> in your
-<a href="../general/controllers.html">controller</a> constructors, or it can be
-<a href="../general/autoloader.html">auto-loaded</a> by the system.
-For the most part the session class will run unattended in the background, so simply initializing the class
-will cause it to read, create, and update sessions.</p>
-
-
-<p>To initialize the Session class manually in your controller constructor, use the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('session');</code>
-<p>Once loaded, the Sessions library object will be available using: <dfn>$this->session</dfn></p>
-
-
-<h2>How do Sessions work?</h2>
-
-<p>When a page is loaded, the session class will check to see if valid session data exists in the user's session cookie.
-If sessions data does <strong>not</strong> exist (or if it has expired) a new session will be created and saved in the cookie.
-If a session does exist, its information will be updated and the cookie will be updated. With each update, the session_id will be regenerated.</p>
-
-<p>It's important for you to understand that once initialized, the Session class runs automatically.  There is nothing
-you need to do to cause the above behavior to happen.  You can, as you'll see below, work with session data or
-even add your own data to a user's session, but the process of reading, writing, and updating a session is automatic.</p>
-
-
-<h2>What is Session Data?</h2>
-
-<p>A <em>session</em>, as far as CodeIgniter is concerned, is simply an array containing the following information:</p>
-
-<ul>
-<li>The user's unique Session ID (this is a statistically random string with very strong entropy, hashed with MD5 for portability, and regenerated (by default) every five minutes)</li>
-<li>The user's IP Address</li>
-<li>The user's User Agent data (the first 120 characters of the browser data string)</li>
-<li>The "last activity" time stamp.</li>
-</ul>
-
-<p>The above data is stored in a cookie as a serialized array with this prototype:</p>
-
-<code>[array]<br />
-(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'session_id'&nbsp;&nbsp;&nbsp;&nbsp;=> random hash,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ip_address'&nbsp;&nbsp;&nbsp;&nbsp;=> 'string - user IP address',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'user_agent'&nbsp;&nbsp;&nbsp;&nbsp;=> 'string - user agent data',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'last_activity' => timestamp<br />
-)</code>
-
-<p>If you have the encryption option enabled, the serialized array will be encrypted before being stored in the cookie,
-making the data highly secure and impervious to being read or altered by someone. More info regarding encryption
-can be <a href="encryption.html">found here</a>, although the Session class will take care of initializing
-and encrypting the data automatically.</p>
-
-<p>Note: Session cookies are only updated every five minutes by default to reduce processor load.  If you repeatedly reload a page
-you'll notice that the "last activity" time only updates if five minutes or more has passed since the last time
-the cookie was written. This time is configurable by changing the $config['sess_time_to_update'] line in your system/config/config.php file.</p>
-
-<h2>Retrieving Session Data</h2>
-
-<p>Any piece of information from the session array is available using the following function:</p>
-
-<code>$this->session->userdata('<samp>item</samp>');</code>
-
-<p>Where <samp>item</samp> is the array index corresponding to the item you wish to fetch.  For example, to fetch the session ID you
-will do this:</p>
-
-<code>$session_id = $this->session->userdata('<samp>session_id</samp>');</code>
-
-<p><strong>Note:</strong> The function returns FALSE (boolean) if the item you are trying to access does not exist.</p>
-
-
-<h2>Adding Custom Session Data</h2>
-
-<p>A useful aspect of the session array is that you can add your own data to it and it will be stored in the user's cookie.
-Why would you want to do this?  Here's one example:</p>
-
-<p>Let's say a particular user logs into your site. Once authenticated,
-you could add their username and email address to the session cookie, making that data globally available to you without
-having to run a database query when you need it.</p>
-
-<p>To add your data to the session array involves passing an array containing your new data to this function:</p>
-
-<code>$this->session->set_userdata(<samp>$array</samp>);</code>
-
-<p>Where <samp>$array</samp> is an associative array containing your new data.  Here's an example:</p>
-
-
-<p><code>$newdata = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'username'&nbsp; => 'johndoe',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'email'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'johndoe@some-site.com',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'logged_in' => TRUE<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-	<br />
-	$this->session->set_userdata(<samp>$newdata</samp>);</code></p>
-<p>If you want to add userdata one value at a time, set_userdata() also supports this syntax. </p>
-<p><code>$this-&gt;session-&gt;set_userdata('some_name', 'some_value');</code></p>
-<p class="important"><strong>Note:</strong> Cookies can only hold 4KB of data, so be careful not to exceed the capacity.  The
-encryption process in particular produces a longer data string than the original so keep careful track of how much data you are storing.</p>
-
-<h2>Retrieving All Session Data</h2>
-<p>An array of all userdata can be retrieved as follows:</p>
-<code>$this-&gt;session-&gt;all_userdata()</code>
-
-<p>And returns an associative array like the following:</p>
-
-<pre>
-Array
-(
-    [session_id] => 4a5a5dca22728fb0a84364eeb405b601
-    [ip_address] => 127.0.0.1
-    [user_agent] => Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_7;
-    [last_activity] => 1303142623
-)
-</pre>
-
-
-<h2>Removing Session Data</h2>
-<p>Just as set_userdata() can be used to add information into a session, unset_userdata() can be used to remove it, by passing the session key. For example, if you wanted to remove 'some_name' from your session information: </p>
-<p><code>$this-&gt;session-&gt;unset_userdata('some_name');</code></p>
-<p>This function can also be passed an associative array of items to unset.</p>
-<p><code>$array_items = array('username' => '', 'email' => '');<br />
-<br />
-$this-&gt;session-&gt;unset_userdata(<samp>$array_items</samp>);</code></p>
-<h2>Flashdata</h2>
-<p>CodeIgniter supports &quot;flashdata&quot;, or session data that will only be available for the next server request, and are then automatically cleared. These can be very useful, and are typically used for informational or status messages (for example: &quot;record 2 deleted&quot;).</p>
-<p>Note: Flash variables are prefaced with &quot;flash_&quot; so avoid this prefix in your own session names.</p>
-<p>To add flashdata:</p>
-<p><code>$this-&gt;session-&gt;set_flashdata('item', 'value');</code></p>
-<p>You can also pass an array to set_flashdata(), in the same manner as set_userdata(). </p>
-<p>To read a flashdata variable:</p>
-<p><code>$this-&gt;session-&gt;flashdata('item');</code></p>
-<p>If you find that you need to preserve a flashdata variable through an additional request, you can do so using the keep_flashdata() function.</p>
-<p><code>$this-&gt;session-&gt;keep_flashdata('item');</code></p>
-<h2>Saving Session Data to a Database</h2>
-<p>While the session data array stored in the user's cookie contains a Session ID,
-unless you store session data in a database there is no way to validate it.  For some applications that require little or no
-security, session ID validation may not be needed, but if your application requires security, validation is mandatory.  Otherwise, an old session
-could be restored by a user modifying their cookies.</p>
-
-<p>When session data is available in a database, every time a valid session is found in the user's cookie, a database
-query is performed to match it.  If the session ID does not match, the session is destroyed.  Session IDs can never
-be updated, they can only be generated when a new session is created.</p>
-
-
-<p>In order to store sessions, you must first create a database table for this purpose.  Here is the basic
-prototype (for MySQL) required by the session class:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-CREATE TABLE IF NOT EXISTS  `ci_sessions` (
-	session_id varchar(40) DEFAULT '0' NOT NULL,
-	ip_address varchar(16) DEFAULT '0' NOT NULL,
-	user_agent varchar(120) NOT NULL,
-	last_activity int(10) unsigned DEFAULT 0 NOT NULL,
-	user_data text NOT NULL,
-	PRIMARY KEY (session_id),
-	KEY `last_activity_idx` (`last_activity`)
-);
-</textarea>
-
-<p><strong>Note:</strong> By default the table is called <dfn>ci_sessions</dfn>, but you can name it anything you want
-as long as you update the <kbd>application/config/config.php</kbd> file so that it contains the name you have chosen.
-Once you have created your database table you can enable the database option in your config.php file as follows:</p>
-
-<code>$config['sess_use_database'] = TRUE;</code>
-
-<p>Once enabled, the Session class will store session data in the DB.</p>
-
-<p>Make sure you've specified the table name in your config file as well:</p>
-
-<code>$config['sess_table_name'] = 'ci_sessions';</code>
-
-<p class="important"><strong>Note:</strong> The Session class has built-in garbage collection which clears out expired sessions so you
-do not need to write your own routine to do it.</p>
-
-
-<h2>Destroying a Session </h2>
-<p>To clear the current session: </p>
-<code>$this-&gt;session-&gt;sess_destroy();</code>
-<p class="important"><strong>Note:</strong> This function should be the last one called, and even flash variables will no longer be available.  If you only want some items destroyed and not all, use <dfn>unset_userdata()</dfn>.</p>
-
-
-
-<h2>Session Preferences</h2>
-<p>You'll find the following Session related preferences in your <kbd>application/config/config.php</kbd> file:</p>
-
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">

-<h1>HTML Table Class</h1>
-
-<p>The Table Class provides functions that enable you to auto-generate HTML tables from arrays or database result sets.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Table class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('table');</code>
-<p>Once loaded, the Table library object will be available using: <dfn>$this->table</dfn></p>
-
-
-<h2>Examples</h2>
-
-<p>Here is an example showing how you can create a table from a multi-dimensional array.
-Note that the first array index will become the table heading (or you can set your own headings using the
-<dfn>set_heading()</dfn> function described in the function reference below).</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Name', 'Color', 'Size'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Fred', 'Blue', 'Small'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Mary', 'Red', 'Large'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('John', 'Green', 'Medium')	<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo $this->table->generate($data);
-</code>
-
-<p>Here is an example of a table created from a database query result. The table class will automatically generate the
-headings based on the table names (or you can set your own headings using the <dfn>set_heading()</dfn> function described
-in the function reference below).</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$query = $this->db->query("SELECT * FROM my_table");<br />
-<br />
-echo $this->table->generate($query);
-</code>
-
-
-<p>Here is an example showing how you might create a table using discrete parameters:</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$this->table->set_heading('Name', 'Color', 'Size');<br />
-<br />
-$this->table->add_row('Fred', 'Blue', 'Small');<br />
-$this->table->add_row('Mary', 'Red', 'Large');<br />
-$this->table->add_row('John', 'Green', 'Medium');<br />
-<br />
-echo $this->table->generate();
-</code>
-
-<p>Here is the same example, except instead of individual parameters, arrays are used:</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$this->table->set_heading(array('Name', 'Color', 'Size'));<br />
-<br />
-$this->table->add_row(array('Fred', 'Blue', 'Small'));<br />
-$this->table->add_row(array('Mary', 'Red', 'Large'));<br />
-$this->table->add_row(array('John', 'Green', 'Medium'));<br />
-<br />
-echo $this->table->generate();
-</code>
-
-
-<h2>Changing the Look of Your Table</h2>
-
-<p>The Table Class permits you to set a table template with which you can specify the design of your layout.  Here is the template
-prototype:</p>
-
-<code>
-$tmpl =  array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'table_open'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;table border="0" cellpadding="4" cellspacing="0">',<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading_row_start'&nbsp;&nbsp;&nbsp;=> '&lt;tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading_row_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading_cell_start'&nbsp;&nbsp;=> '&lt;th>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading_cell_end'&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/th>',<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'row_start'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'row_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'cell_start'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;td>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'cell_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/td>',<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'row_alt_start'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'row_alt_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'cell_alt_start'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;td>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'cell_alt_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/td>',<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'table_close'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/table>'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-
-<br />
-$this->table->set_template($tmpl);
-</code>
-
-<p class="important"><strong>Note:</strong>&nbsp; You'll notice there are two sets of "row" blocks in the template.  These permit you to create alternating row colors or design elements that alternate with each
-iteration of the row data.</p>
-
-<p>You are NOT required to submit a complete template.  If you only need to change parts of the layout you can simply submit those elements.
-In this example, only the table opening tag is being changed:</p>
-
-<code>
-$tmpl =  array ( 'table_open'&nbsp;&nbsp;=> '&lt;table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />
-
-<br />
-$this->table->set_template($tmpl);
-</code>
-
-<br />
-<h1>Function Reference</h1>
-
-<h2>$this->table->generate()</h2>
-<p>Returns a string containing the generated table.  Accepts an optional parameter which can be an array or a database result object.</p>
-
-<h2>$this->table->set_caption()</h2>
-
-<p>Permits you to add a caption to the table.</p>
-
-<code>$this->table->set_caption('Colors');</code>
-
-<h2>$this->table->set_heading()</h2>
-
-<p>Permits you to set the table heading.  You can submit an array or discrete params:</p>
-
-<code>$this->table->set_heading('Name', 'Color', 'Size');</code>
-<code>$this->table->set_heading(array('Name', 'Color', 'Size'));</code>
-
-<h2>$this->table->add_row()</h2>
-
-<p>Permits you to add a row to your table.  You can submit an array or discrete params:</p>
-
-<code>$this->table->add_row('Blue', 'Red', 'Green');</code>
-<code>$this->table->add_row(array('Blue', 'Red', 'Green'));</code>
-
-<p>If you would like to set an individual cell's tag attributes, you can use an associative array for that cell.  The associative key <dfn>'data'</dfn> defines the cell's data.  Any other key =&gt; val pairs are added as <dfn>key='val'</dfn> attributes to the tag:</p>
-
-<code>$cell = array('data' => 'Blue', 'class' => 'highlight', 'colspan' => 2);<br />
-$this->table->add_row($cell, 'Red', 'Green');<br />
-<br />
-// generates<br />
-// &lt;td class='highlight' colspan='2'&gt;Blue&lt;/td&gt;&lt;td&gt;Red&lt;/td&gt;&lt;td&gt;Green&lt;/td&gt;
-</code>
-
-<h2>$this->table->make_columns()</h2>
-
-<p>This function takes a one-dimensional array as input and creates
-a multi-dimensional array with a depth equal to the number of
-columns desired.  This allows a single array with many elements to  be
-displayed in a table that has a fixed column count.  Consider this example:</p>
-
-<code>
-$list = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve');<br />
-<br />
-$new_list = $this->table->make_columns($list, 3);<br />
-<br />
-$this->table->generate($new_list);<br />
-<br />
-// Generates a table with this prototype<br />
-<br />
-&lt;table border="0" cellpadding="4" cellspacing="0"&gt;<br />
-&lt;tr&gt;<br />
-&lt;td&gt;one&lt;/td&gt;&lt;td&gt;two&lt;/td&gt;&lt;td&gt;three&lt;/td&gt;<br />
-&lt;/tr&gt;&lt;tr&gt;<br />
-&lt;td&gt;four&lt;/td&gt;&lt;td&gt;five&lt;/td&gt;&lt;td&gt;six&lt;/td&gt;<br />
-&lt;/tr&gt;&lt;tr&gt;<br />
-&lt;td&gt;seven&lt;/td&gt;&lt;td&gt;eight&lt;/td&gt;&lt;td&gt;nine&lt;/td&gt;<br />
-&lt;/tr&gt;&lt;tr&gt;<br />
-&lt;td&gt;ten&lt;/td&gt;&lt;td&gt;eleven&lt;/td&gt;&lt;td&gt;twelve&lt;/td&gt;&lt;/tr&gt;<br />
-&lt;/table&gt;</code>
-
-
-
-<h2>$this->table->set_template()</h2>
-
-<p>Permits you to set your template. You can submit a full or partial template.</p>
-
-<code>
-$tmpl =  array ( 'table_open'&nbsp;&nbsp;=> '&lt;table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />
-
-<br />
-$this->table->set_template($tmpl);
-</code>
-
-
-<h2>$this->table->set_empty()</h2>
-
-<p>Let's you set a default value for use in any table cells that are empty.  You might, for example, set a non-breaking space:</p>
-
-<code>
-$this->table->set_empty("&amp;nbsp;");
-</code>
-
-<h2>$this->table->clear()</h2>
-
-<p>Lets you clear the table heading and row data.  If you need to show multiple tables with different data you should
-to call this function after each table has been generated to empty the previous table information. Example:</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$this->table->set_heading('Name', 'Color', 'Size');<br />
-$this->table->add_row('Fred', 'Blue', 'Small');<br />
-$this->table->add_row('Mary', 'Red', 'Large');<br />
-$this->table->add_row('John', 'Green', 'Medium');<br />
-<br />
-echo $this->table->generate();<br />
-<br />
-<kbd>$this->table->clear();</kbd><br />
-<br />
-$this->table->set_heading('Name', 'Day', 'Delivery');<br />
-$this->table->add_row('Fred', 'Wednesday', 'Express');<br />
-$this->table->add_row('Mary', 'Monday', 'Air');<br />
-$this->table->add_row('John', 'Saturday', 'Overnight');<br />
-<br />
-echo $this->table->generate();
-</code>
-
-<h2>$this->table->function</h2>
-
-<p>Allows you to specify a native PHP function or a valid function array object to be applied to all cell data.</p>
-
-<code>$this->load->library('table');<br />
-<br />
-$this->table->set_heading('Name', 'Color', 'Size');<br />
-$this->table->add_row('Fred', '&lt;strong&gt;Blue&lt;/strong&gt;', 'Small');<br />
-<br />
-$this->table->function = 'htmlspecialchars';<br />
-echo $this->table->generate();<br />
-</code>
-
-<p>In the above example, all cell data would be ran through PHP's <dfn>htmlspecialchars()</dfn> function, resulting in:</p>
-
-<code>&lt;td&gt;Fred&lt;/td&gt;&lt;td&gt;&amp;lt;strong&amp;gt;Blue&amp;lt;/strong&amp;gt;&lt;/td&gt;&lt;td&gt;Small&lt;/td&gt;</code>

-<h1>Trackback Class</h1>
-
-<p>The Trackback Class provides functions that enable you to send and receive Trackback data.</p>
-
-
-<p>If you are not familiar with Trackbacks you'll find more information <a href="http://en.wikipedia.org/wiki/Trackback">here</a>.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Trackback class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('trackback');</code>
-<p>Once loaded, the Trackback library object will be available using: <dfn>$this->trackback</dfn></p>
-
-
-<h2>Sending Trackbacks</h2>
-
-<p>A Trackback can be sent from any of your controller functions using code similar to this example:</p>
-
-<code>$this->load->library('trackback');<br />
-<br />
-$tb_data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ping_url'&nbsp;&nbsp;=> 'http://example.com/trackback/456',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'url'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'http://www.my-example.com/blog/entry/123',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'The Title of My Entry',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'excerpt'&nbsp;&nbsp;&nbsp;=> 'The entry content.',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_name' => 'My Blog Name',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'charset'&nbsp;&nbsp;&nbsp;=> 'utf-8'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-if ( ! $this->trackback->send($tb_data))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $this->trackback->display_errors();<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo 'Trackback was sent!';<br />
-}</code>
-
-<p>Description of array data:</p>
-
-<ul>
-<li><strong>ping_url</strong> - The URL of the site you are sending the Trackback to. You can send Trackbacks to multiple URLs by separating each URL with a comma.</li>
-<li><strong>url</strong> - The URL to YOUR site where the weblog entry can be seen.</li>
-<li><strong>title</strong> - The title of your weblog entry.</li>
-<li><strong>excerpt</strong> - The content of your weblog entry. Note: the Trackback class will automatically send only the first 500 characters of your entry.  It will also strip all HTML.</li>
-<li><strong>blog_name</strong> - The name of your weblog.</li>
-<li><strong>charset</strong> - The character encoding your weblog is written in.  If omitted, UTF-8 will be used.</li>
-</ul>
-
-<p>The Trackback sending function returns TRUE/FALSE (boolean) on success or failure.  If it fails, you can retrieve the error message using:</p>
-
-<code>$this->trackback->display_errors();</code>
-
-
-<h2>Receiving Trackbacks</h2>
-
-<p>Before you can receive Trackbacks you must create a weblog.  If you don't have a blog yet there's no point in continuing.</p>
-
-<p>Receiving Trackbacks is a little more complex than sending them, only because you will need a database table in which to store them,
-and you will need to validate the incoming trackback data.  You are encouraged to implement a thorough validation process to
-guard against spam and duplicate data.  You may also want to limit the number of Trackbacks you allow from a particular IP within
-a given span of time to further curtail spam.  The process of receiving a Trackback is quite simple;
-the validation is what takes most of the effort.</p>
-
-<h2>Your Ping URL</h2>
-
-<p>In order to accept Trackbacks you must display a Trackback URL next to each one of your weblog entries.  This will be the URL
-that people will use to send you Trackbacks (we will refer to this as your "Ping URL").</p>
-
-<p>Your Ping URL must point to a controller function where your Trackback receiving code is located, and the URL
-must contain the ID number for each particular entry, so that when the Trackback is received you'll be
-able to associate it with a particular entry.</p>
-
-<p>For example, if your controller class is called <dfn>Trackback</dfn>, and the receiving function is called <dfn>receive</dfn>, your
-Ping URLs will look something like this:</p>
-
-<code>http://example.com/index.php/trackback/receive/<samp>entry_id</samp></code>
-
-<p>Where <samp>entry_id</samp> represents the individual ID number for each of your entries.</p>
-
-
-<h2>Creating a Trackback Table</h2>
-
-<p>Before you can receive Trackbacks you must create a table in which to store them.  Here is a basic prototype for such a table:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="13">
-CREATE TABLE trackbacks (
- tb_id int(10) unsigned NOT NULL auto_increment,
- entry_id int(10) unsigned NOT NULL default 0,
- url varchar(200) NOT NULL,
- title varchar(100) NOT NULL,
- excerpt text NOT NULL,
- blog_name varchar(100) NOT NULL,
- tb_date int(10) NOT NULL,
- ip_address varchar(16) NOT NULL,
- PRIMARY KEY `tb_id` (`tb_id`),
- KEY `entry_id` (`entry_id`)
-);</textarea>
-
-
-<p>The Trackback specification only requires four pieces of information to be sent in a Trackback (url, title, excerpt, blog_name),
-but to make the data more useful we've added a few more fields in the above table schema (date, IP address, etc.).</p>
-
-<h2>Processing a Trackback</h2>
-
-<p>Here is an example showing how you will receive and process a Trackback.  The following
-code is intended for use within the controller function where you expect to receive Trackbacks.</p>
-
-<code>$this->load->library('trackback');<br />
-$this->load->database();<br />
-<br />
-if ($this->uri->segment(3) == FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->trackback->send_error("Unable to determine the entry ID");<br />
-}<br />
-<br />
-if ( ! $this->trackback->receive())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->trackback->send_error("The Trackback did not contain valid data");<br />
-}<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tb_id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'entry_id'&nbsp;&nbsp;&nbsp;=> $this->uri->segment(3),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'url'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> $this->trackback->data('url'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> $this->trackback->data('title'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'excerpt'&nbsp;&nbsp;&nbsp;&nbsp;=> $this->trackback->data('excerpt'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_name'&nbsp;&nbsp;=> $this->trackback->data('blog_name'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tb_date'&nbsp;&nbsp;&nbsp;&nbsp;=> time(),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ip_address' => $this->input->ip_address()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$sql = $this->db->insert_string('trackbacks', $data);<br />
-$this->db->query($sql);<br />
-<br />
-$this->trackback->send_success();</code>
-
-<h4>Notes:</h4>
-
-<p>The entry ID number is expected in the third segment of your URL.  This is based on the URI example we gave earlier:</p>
-
-<code>http://example.com/index.php/trackback/receive/<samp>entry_id</samp></code>
-
-<p>Notice the entry_id is in the third URI segment, which you can retrieve using:</p>
-
-<code>$this->uri->segment(3);</code>
-
-<p>In our Trackback receiving code above, if the third segment is missing, we will issue an error.  Without a valid entry ID, there's no
-reason to continue.</p>
-
-<p>The <dfn>$this->trackback->receive()</dfn> function is simply a validation function that looks at the incoming data
-and makes sure it contains the four pieces of data that are required (url, title, excerpt, blog_name).
-It returns TRUE on success and FALSE on failure.  If it fails you will issue an error message.</p>
-
-<p>The incoming Trackback data can be retrieved using this function:</p>
-
-<code>$this->trackback->data('<var>item</var>')</code>
-
-<p>Where <var>item</var> represents one of these four pieces of info: url, title, excerpt, or blog_name</p>
-
-<p>If the Trackback data is successfully received, you will issue a success message using:</p>
-
-<code>$this->trackback->send_success();</code>
-
-<p class="important"><strong>Note:</strong> The above code contains no data validation, which you are encouraged to add.</p>

-<h1>Typography Class</h1>
-
-<p>The Typography Class provides functions that help you format text.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Typography class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('typography');</code>
-<p>Once loaded, the Typography library object will be available using: <dfn>$this->typography</dfn></p>
-
-
-<h2>auto_typography()</h2>
-
-<p>Formats text so that it is semantically and typographically correct HTML.  Takes a string as input and returns it with
-the following formatting:</p>
-
-<ul>
-<li>Surrounds paragraphs within &lt;p&gt;&lt;/p&gt; (looks for double line breaks to identify paragraphs).</li>
-<li>Single line breaks are converted to &lt;br /&gt;, except those that appear within &lt;pre&gt; tags.</li>
-<li>Block level elements, like &lt;div&gt; tags, are not wrapped within paragraphs, but their contained text is if it contains paragraphs.</li>
-<li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li>
-<li>Apostrophes are converted to curly apostrophe entities.</li>
-<li>Double dashes (either like -- this or like--this) are converted to em&#8212;dashes.</li>
-<li>Three consecutive periods either preceding or following a word are converted to ellipsis&#8230;</li>
-<li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li>
-</ul>
-
-<p>Usage example:</p>
-
-<code>$string = $this->typography->auto_typography($string);</code>
-
-<h3>Parameters</h3>
-
-<p>There is one optional parameters that determines whether the parser should reduce more then two consecutive line breaks down to two. Use boolean <kbd>TRUE</kbd> or <kbd>FALSE</kbd>.</p>
-
-<p>By default the parser does not reduce line breaks. In other words, if no parameters are submitted, it is the same as doing this:</p>
-
-<code>$string = $this->typography->auto_typography($string, <kbd>FALSE</kbd>);</code>
-
-
-<p class="important"><strong>Note:</strong> Typographic formatting can be processor intensive, particularly if you have a lot of content being formatted.
-If you choose to use this function you may want to consider
-<a href="../general/caching.html">caching</a> your pages.</p>
-
-
-
-<h2>format_characters()</h2>
-
-<p>This function is similar to the <dfn>auto_typography</dfn> function above, except that it only does character conversion:</p>
-
-<ul>
-<li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li>
-<li>Apostrophes are converted to curly apostrophe entities.</li>
-<li>Double dashes (either like -- this or like--this) are converted to em&#8212;dashes.</li>
-<li>Three consecutive periods either preceding or following a word are converted to ellipsis&#8230;</li>
-<li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li>
-</ul>
-
-<p>Usage example:</p>
-
-<code>$string = $this->typography->format_characters($string);</code>
-
-
-<h2>nl2br_except_pre()</h2>
-
-<p>Converts newlines to &lt;br /&gt; tags unless they appear within &lt;pre&gt; tags.
-This function is identical to the native PHP <dfn>nl2br()</dfn> function, except that it ignores &lt;pre&gt; tags.</p>
-
-<p>Usage example:</p>
-
-<code>$string = $this->typography->nl2br_except_pre($string);</code>
-
-<h2>protect_braced_quotes</h2>
-
-<p>When using the Typography library in conjunction with the Template Parser library it can often be desirable to protect single
-	and double quotes within curly braces.  To enable this, set the <kbd>protect_braced_quotes</kbd> class property to <samp>TRUE</samp>.</p>
-
-<p>Usage example:</p>
-
-<code>$this->load->library('typography');<br />
-$this->typography->protect_braced_quotes = TRUE;
-</code>

-<h1>Unit Testing Class</h1>
-
-<p>Unit testing is an approach to software development in which tests are written for each function in your application.
-If you are not familiar with the concept you might do a little googling on the subject.</p>
-
-<p>CodeIgniter's Unit Test class is quite simple, consisting of an evaluation function and two result functions.
-It's not intended to be a full-blown test suite but rather a simple mechanism to evaluate your code
-to determine if it is producing the correct data type and result.
-</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Unit Test class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('unit_test');</code>
-<p>Once loaded, the Unit Test object will be available using: <dfn>$this->unit</dfn></p>
-
-
-<h2>Running Tests</h2>
-
-<p>Running a test involves supplying a test and an expected result to the following function:</p>
-
-<h2>$this->unit->run( <var>test</var>, <var>expected result</var>, '<var>test name</var>', '<var>notes</var>');</h2>
-
-<p>Where <var>test</var> is the result of the code you wish to test, <var>expected result</var> is the data type you expect,
-<var>test name</var> is an optional name you can give your test, and <var>notes</var> are optional notes. Example:</p>
-
-<code>$test = 1 + 1;<br />
-<br />
-$expected_result = 2;<br />
-<br />
-$test_name = 'Adds one plus one';<br />
-<br />
-$this->unit->run($test, $expected_result, $test_name);</code>
-
-<p>The expected result you supply can either be a literal match, or a data type match.  Here's an example of a literal:</p>
-
-<code>$this->unit->run('Foo', 'Foo');</code>
-
-<p>Here is an example of a data type match:</p>
-
-<code>$this->unit->run('Foo', 'is_string');</code>
-
-<p>Notice the use of "is_string" in the second parameter?  This tells the function to evaluate whether your test is producing a string
-as the result.  Here is a list of allowed comparison types:</p>
-
-<ul>
-<li>is_object</li>
-<li>is_string</li>
-<li>is_bool</li>
-<li>is_true</li>
-<li>is_false</li>
-<li>is_int</li>
-<li>is_numeric</li>
-<li>is_float</li>
-<li>is_double</li>
-<li>is_array</li>
-<li>is_null</li>
-</ul>
-
-
-<h2>Generating Reports</h2>
-
-<p>You can either display results after each test, or your can run several tests and generate a report at the end.
-To show a report directly simply echo or return the <var>run</var> function:</p>
-
-<code>echo $this->unit->run($test, $expected_result);</code>
-
-<p>To run a full report of all tests, use this:</p>
-
-<code>echo $this->unit->report();</code>
-
-<p>The report will be formatted in an HTML table for viewing.  If you prefer the raw data you can retrieve an array using:</p>
-
-<code>echo $this->unit->result();</code>
-
-
-<h2>Strict Mode</h2>
-
-<p>By default the unit test class evaluates literal matches loosely.  Consider this example:</p>
-
-<code>$this->unit->run(1, TRUE);</code>
-
-<p>The test is evaluating an integer, but the expected result is a boolean.  PHP, however, due to it's loose data-typing
-will evaluate the above code as TRUE using a normal equality test:</p>
-
-<code>if (1 == TRUE) echo 'This evaluates as true';</code>
-
-<p>If you prefer, you can put the unit test class in to strict mode, which will compare the data type as well as the value:</p>
-
-<code>if (1 === TRUE) echo 'This evaluates as FALSE';</code>
-
-<p>To enable strict mode use this:</p>
-
-<code>$this->unit->use_strict(TRUE);</code>
-
-<h2>Enabling/Disabling Unit Testing</h2>
-
-<p>If you would like to leave some testing in place in your scripts, but not have it run unless you need it, you can disable
-unit testing using:</p>
-
-<code>$this->unit->active(FALSE)</code>
-
-<h2>Unit Test Display</h2>
-
-<p>When your unit test results display, the following items show by default:</p>
-
-<ul>
-	<li>Test Name (test_name)</li>
-	<li>Test Datatype (test_datatype)</li>
-	<li>Expected Datatype (res_datatype)</li>
-	<li>Result (result)</li>
-	<li>File Name (file)</li>
-	<li>Line Number (line)</li>
-	<li>Any notes you entered for the test (notes)</li>
-</ul>
-
-You can customize which of these items get displayed by using <kbd>$this->unit->set_items()</kbd>. For example, if you only wanted the test name and the result displayed:</p>
-
-<h3>Customizing displayed tests</h3>
-
-<code>
-	$this->unit->set_test_items(array('test_name', 'result'));
-</code>
-
-<h3>Creating a Template</h3>
-
-<p>If you would like your test results formatted differently then the default you can set your own template.  Here is an
-example of a simple template.  Note the required pseudo-variables:</p>
-
-<code>
-$str = '<br />
-&lt;table border="0" cellpadding="4" cellspacing="1"><br />
-&nbsp;&nbsp;&nbsp;&nbsp;<kbd>{rows}</kbd><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;tr><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;td><kbd>{item}</kbd>&lt;/td><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;td><kbd>{result}</kbd>&lt;/td><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;/tr><br />
-&nbsp;&nbsp;&nbsp;&nbsp;<kbd>{/rows}</kbd><br />
-&lt;/table>';<br />
-<br />
-$this->unit->set_template($str);
-</code>
-
-<p class="important"><strong>Note:</strong> Your template must be declared <strong>before</strong> running the unit test process.</p>

-<h1>URI Class</h1>
-
-<p>The URI Class provides functions that help you retrieve information from your URI strings. If you use URI routing, you can
-also retrieve information about the re-routed segments.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-<h2>$this->uri->segment(<var>n</var>)</h2>
-
-<p>Permits you to retrieve a specific segment. Where <var>n</var> is the segment number you wish to retrieve.
-Segments are numbered from left to right. For example, if your full URL is this:</p>
-
-<code>http://example.com/index.php/news/local/metro/crime_is_up</code>
-
-<p>The segment numbers would be this:</p>
-
-<ol>
-<li>news</li>
-<li>local</li>
-<li>metro</li>
-<li>crime_is_up</li>
-</ol>
-
-<p>By default the function returns FALSE (boolean) if the segment does not exist. There is an optional second parameter that
-permits you to set your own default value if the segment is missing.
-For example, this would tell the function to return the number zero in the event of failure:</p>
-
-<code>$product_id = $this->uri->segment(3, 0);</code>
-
-<p>It helps avoid having to write code like this:</p>
-
-<code>if ($this->uri->segment(3) === FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$product_id = 0;<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$product_id = $this->uri->segment(3);<br />
-}<br />
-</code>
-
-<h2>$this->uri->rsegment(<var>n</var>)</h2>
-
-<p>This function is identical to the previous one, except that it lets you retrieve a specific segment from your
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-<h2>$this->uri->slash_segment(<var>n</var>)</h2>
-
-<p>This function is almost identical to <dfn>$this->uri->segment()</dfn>, except it adds a trailing and/or leading slash based on the second
-parameter.  If the parameter is not used, a trailing slash added.  Examples:</p>
-
-<code>$this->uri->slash_segment(<var>3</var>);<br />
-$this->uri->slash_segment(<var>3</var>, 'leading');<br />
-$this->uri->slash_segment(<var>3</var>, 'both');</code>
-
-<p>Returns:</p>
-
-<ol>
-<li>segment/</li>
-<li>/segment</li>
-<li>/segment/</li>
-</ol>
-
-
-<h2>$this->uri->slash_rsegment(<var>n</var>)</h2>
-
-<p>This function is identical to the previous one, except that it lets you add slashes a specific segment from your
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-
-<h2>$this->uri->uri_to_assoc(<var>n</var>)</h2>
-
-<p>This function lets you turn URI segments into and associative array of key/value pairs.  Consider this URI:</p>
-
-<code>index.php/user/search/name/joe/location/UK/gender/male</code>
-
-<p>Using this function you can turn the URI into an associative array with this prototype:</p>
-
-<code>[array]<br />
-(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'joe'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'location'	=> 'UK'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'gender'	=> 'male'<br />
-)</code>
-
-<p>The first parameter of the function lets you set an offset.  By default it is set to <kbd>3</kbd> since your
-URI will normally contain a controller/function in the first and second segments. Example:</p>
-
-<code>
-$array = $this->uri->uri_to_assoc(3);<br />
-<br />
-echo $array['name'];
-</code>
-
-
-<p>The second parameter lets you set default key names, so that the array returned by the function will always contain expected indexes, even if missing from the URI. Example:</p>
-
-<code>
-$default = array('name', 'gender', 'location', 'type', 'sort');<br />
-<br />
-$array = $this->uri->uri_to_assoc(3, $default);</code>
-
-<p>If the URI does not contain a value in your default, an array index will be set to that name, with a value of FALSE.</p>
-
-<p>Lastly, if a corresponding value is not found for a given key (if there is an odd number of URI segments) the value will be set to FALSE (boolean).</p>
-
-
-<h2>$this->uri->ruri_to_assoc(<var>n</var>)</h2>
-
-<p>This function is identical to the previous one, except that it creates an associative array using the
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-<h2>$this->uri->assoc_to_uri()</h2>
-
-<p>Takes an associative array as input and generates a URI string from it.  The array keys will be included in the string.  Example:</p>
-
-<code>$array = array('product' => 'shoes', 'size' => 'large', 'color' => 'red');<br />
-<br />
-$str = $this->uri->assoc_to_uri($array);<br />
-<br />
-// Produces:  product/shoes/size/large/color/red
-</code>
-
-
-<h2>$this->uri->uri_string()</h2>
-
-<p>Returns a string with the complete URI.  For example, if this is your full URL:</p>
-
-<code>http://example.com/index.php/news/local/345</code>
-
-<p>The function would return this:</p>
-
-<code>/news/local/345</code>
-
-
-<h2>$this->uri->ruri_string()</h2>
-
-<p>This function is identical to the previous one, except that it returns the
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-
-<h2>$this->uri->total_segments()</h2>
-
-<p>Returns the total number of segments.</p>
-
-
-<h2>$this->uri->total_rsegments()</h2>
-
-<p>This function is identical to the previous one, except that it returns the total number of segments in your
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-
-<h2>$this->uri->segment_array()</h2>
-
-<p>Returns an array containing the URI segments.  For example:</p>
-
-<code>
-$segs = $this->uri->segment_array();<br />
-<br />
-foreach ($segs as $segment)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $segment;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo '&lt;br />';<br />
-}</code>
-
-<h2>$this->uri->rsegment_array()</h2>
-
-<p>This function is identical to the previous one, except that it returns the array of segments in your
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>

-<h1>User Agent Class</h1>
-
-<p>The User Agent Class provides functions that help identify information about the browser, mobile device, or robot visiting your site.
-In addition you can get referrer information as well as language and supported character-set information.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the User Agent class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('user_agent');</code>
-<p>Once loaded, the object will be available using: <dfn>$this->agent</dfn></p>
-
-<h2>User Agent Definitions</h2>
-
-<p>The user agent name definitions are located in a config file located at: <dfn>application/config/user_agents.php</dfn>.  You may add items to the
-various user agent arrays if needed.</p>
-
-<h2>Example</h2>
-
-<p>When the User Agent class is initialized it will attempt to determine whether the user agent browsing your site is
-a web browser, a mobile device, or a robot.  It will also gather the platform information if it is available.</p>
-
-
-<code>
-$this->load->library('user_agent');<br />
-<br />
-if ($this->agent->is_browser())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$agent  = $this->agent->browser().' '.$this->agent->version();<br />
-}<br />
-elseif ($this->agent->is_robot())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$agent = $this->agent->robot();<br />
-}<br />
-elseif ($this->agent->is_mobile())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$agent = $this->agent->mobile();<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$agent = 'Unidentified User Agent';<br />
-}<br />
-<br />
-echo $agent;<br />
-<br />
-echo $this->agent->platform(); // Platform info (Windows, Linux, Mac, etc.)
-</code>
-
-
-<h1>Function Reference</h1>
-
-
-<h2>$this->agent->is_browser()</h2>
-<p>Returns TRUE/FALSE (boolean) if the user agent is a known web browser.</p>
-
-<code> if ($this->agent->is_browser('Safari'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo 'You are using Safari.';<br />
-}<br />
-else if ($this->agent->is_browser())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo 'You are using a browser.';<br />
-}</code>

-<p>Returns TRUE/FALSE (boolean) if the user agent is a known robot.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; The user agent library only contains the most common robot

-<h2>$this->agent->is_referral()</h2>
-<p>Returns TRUE/FALSE (boolean) if the user agent was referred from another site.</p>
-
-
-<h2>$this->agent->browser()</h2>
-<p>Returns a string containing the name of the web browser viewing your site.</p>
-
-<h2>$this->agent->version()</h2>
-<p>Returns a string containing the version number of the web browser viewing your site.</p>
-
-<h2>$this->agent->mobile()</h2>
-<p>Returns a string containing the name of the mobile device viewing your site.</p>

-}</code>
-
-
-<h2>$this->agent->agent_string()</h2>
-<p>Returns a string containing the full user agent string.  Typically it will be something like this:</p>

-<h1>XML-RPC and XML-RPC Server Classes</h1>
-
-
-<p>CodeIgniter's XML-RPC classes permit you to send requests to another server, or set up
-your own XML-RPC server to receive requests.</p>
-
-
-<h2>What is XML-RPC?</h2>
-
-<p>Quite simply it is a way for two computers to communicate over the internet using XML.
-One computer, which we will call the <dfn>client</dfn>, sends an XML-RPC <strong>request</strong> to
-another computer, which we will call the <dfn>server</dfn>.  Once the server receives and processes the request it
-will send back a <strong>response</strong> to the client.</p>
-
-<p>For example, using the MetaWeblog API, an XML-RPC Client (usually a desktop publishing tool) will
-send a request to an XML-RPC Server running on your site.  This request might be a new weblog entry
-being sent for publication, or it could be a request for an existing entry for editing.
-
-When the XML-RPC Server receives this request it will examine it to determine which class/method should be called to process the request.
-Once processed, the server will then send back a response message.</p>
-
-<p>For detailed specifications, you can visit the <a href="http://www.xmlrpc.com/">XML-RPC</a> site.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the XML-RPC and XML-RPCS classes are initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<p>To load the XML-RPC class you will use:</p>
-<code>$this->load->library('xmlrpc');</code>
-<p>Once loaded, the xml-rpc library object will be available using: <dfn>$this->xmlrpc</dfn></p>
-
-<p>To load the XML-RPC Server class you will use:</p>
-<code>
-$this->load->library('xmlrpc');<br />
-$this->load->library('xmlrpcs');
-</code>
-<p>Once loaded, the xml-rpcs library object will be available using: <dfn>$this->xmlrpcs</dfn></p>
-
-<p class="important"><strong>Note:</strong>&nbsp; When using the XML-RPC Server class you must load BOTH the XML-RPC class and the XML-RPC Server class.</p>
-
-
-
-<h2>Sending XML-RPC Requests</h2>
-
-<p>To send a request to an XML-RPC server you must specify the following information:</p>
-
-<ul>
-<li>The URL of the server</li>
-<li>The method on the server you wish to call</li>
-<li>The <em>request</em> data (explained below).</li>
-</ul>
-
-<p>Here is a basic example that sends a simple Weblogs.com ping to the <a href="http://pingomatic.com/">Ping-o-Matic</a></p>
-
-
-<code>$this->load->library('xmlrpc');<br />
-<br />
-$this->xmlrpc->server('http://rpc.pingomatic.com/', 80);<br />
-$this->xmlrpc->method('weblogUpdates.ping');<br />
-
-<br />
-$request = array('My Photoblog', 'http://www.my-site.com/photoblog/');<br />
-$this->xmlrpc->request($request);<br />
-<br />
-if ( ! $this->xmlrpc->send_request())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $this-&gt;xmlrpc->display_error();<br />
-}</code>
-
-<h3>Explanation</h3>
-
-<p>The above code initializes the XML-RPC class, sets the server URL and method to be called (weblogUpdates.ping).  The
-request (in this case, the title and URL of your site) is placed into an array for transportation, and
-compiled using the request() function.
-Lastly, the full request is sent.  If the <dfn>send_request()</dfn> method returns false we will display the error message
-sent back from the XML-RPC Server.</p>
-
-<h2>Anatomy of a Request</h2>
-
-<p>An XML-RPC <dfn>request</dfn> is simply the data you are sending to the XML-RPC server.  Each piece of data in a request
-is referred to as a <dfn>request parameter</dfn>.  The above example has two parameters:
-The URL and title of your site. When the XML-RPC server receives your request, it will look for parameters it requires.</p>
-
-<p>Request parameters must be placed into an array for transportation, and each parameter can be one
-of seven data types (strings, numbers, dates, etc.). If your parameters are something other than strings
-you will have to include the data type in the request array.</p>
-
-<p>Here is an example of a simple array with three parameters:</p>
-
-<code>$request = array('John', 'Doe', 'www.some-site.com');<br />
-$this->xmlrpc->request($request);</code>
-
-<p>If you use data types other than strings, or if you have several different data types, you will place
-each parameter into its own array, with the data type in the second position:</p>
-
-<code>
-$request = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('John', 'string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Doe', 'string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(FALSE, 'boolean'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(12345, 'int')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);
-<br />
-$this->xmlrpc->request($request);</code>
-
-The  <a href="#datatypes">Data Types</a>  section below has a full list of data types.
-
-
-
-<h2>Creating an XML-RPC Server</h2>
-
-<p>An XML-RPC Server acts as a traffic cop of sorts, waiting for incoming requests and redirecting them to the
-appropriate functions for processing.</p>
-
-<p>To create your own XML-RPC server involves initializing the XML-RPC Server class in your controller where you expect the incoming
-request to appear, then setting up an array with mapping instructions so that incoming requests can be sent to the appropriate
-class and method for processing.</p>
-
-<p>Here is an example to illustrate:</p>
-
-<code>
-$this->load->library('xmlrpc');<br />
-$this->load->library('xmlrpcs');<br />
-<br />
-$config['functions']['<var>new_post</var>'] = array('function' => '<dfn>My_blog.new_entry</dfn>'),<br />
-$config['functions']['<var>update_post</var>'] = array('function' => '<dfn>My_blog.update_entry</dfn>');<br />
-$config['object'] = $this;<br />
-<br />
-$this->xmlrpcs->initialize($config);<br />
-$this->xmlrpcs->serve();</code>
-
-<p>The above example contains an array specifying two method requests that the Server allows.
-The allowed methods are on the left side of the array. When either of those are received, they will be mapped to the class and method on the right.</p>
-
-<p>The '<var>object</var>' key is a special key that you pass an instantiated class object with, which is necessary when the method you are mapping to is not
-	part of the CodeIgniter super object.</p>
-
-<p>In other words, if an XML-RPC Client sends a request for the <var>new_post</var> method, your
-server will load the <dfn>My_blog</dfn> class and call the <dfn>new_entry</dfn> function.
-If the request is for the <var>update_post</var> method, your
-server will load the <dfn>My_blog</dfn> class and call the <dfn>update_entry</dfn> function.</p>
-
-<p>The function names in the above example are arbitrary.  You'll decide what they should be called on your server,
-or if you are using standardized APIs, like the Blogger or MetaWeblog API, you'll use their function names.</p>
-
-<p>There are two additional configuration keys you may make use of when initializing the server class: <var>debug</var> can be set to TRUE in order to enable debugging, and <var>xss_clean</var> may be set to FALSE to prevent sending data through the Security library's xss_clean function.
-
-<h2>Processing Server Requests</h2>
-
-<p>When the XML-RPC Server receives a request and loads the class/method for processing, it will pass
-an object to that method containing the data sent by the client.</p>
-
-<p>Using the above example, if the <var>new_post</var> method is requested, the server will expect a class
-to exist with this prototype:</p>
-
-<code>class <kbd>My_blog</kbd> extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function <kbd>new_post</kbd>(<var>$request</var>)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-	<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}
-</code>
-
-<p>The <var>$request</var> variable is an object compiled by the Server, which contains the data sent by the XML-RPC Client.
-Using this object you will have access to the <em>request parameters</em> enabling you to process the request.  When
-you are done you will send a <dfn>Response</dfn> back to the Client.</p>
-
-<p>Below is a real-world example, using the Blogger API.  One of the methods in the Blogger API is <dfn>getUserInfo()</dfn>.
-Using this method, an XML-RPC Client can send the Server a username and password, in return the Server sends
-back information about that particular user (nickname, user ID, email address, etc.).  Here is how the processing
-function might look:</p>
-
-
-<code>class <kbd>My_blog</kbd> extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function <kbd>getUserInfo</kbd>(<var>$request</var>)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$username = 'smitty';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$password = 'secretsmittypass';<br /><br />
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->library('xmlrpc');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$parameters&nbsp;=&nbsp;$request->output_parameters();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if&nbsp;($parameters['1'] != $username AND $parameters['2'] != $password)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return&nbsp;$this->xmlrpc->send_error_message('100',&nbsp;'Invalid&nbsp;Access');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$response&nbsp;=&nbsp;array(array('nickname'&nbsp;&nbsp;=>&nbsp;array('Smitty','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'userid'&nbsp;&nbsp;&nbsp;&nbsp;=>&nbsp;array('99','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'url'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=>&nbsp;array('http://yoursite.com','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'email'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=>&nbsp;array('jsmith@yoursite.com','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'lastname'&nbsp;&nbsp;=>&nbsp;array('Smith','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'firstname'&nbsp;=>&nbsp;array('John','string')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'struct');<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return $this->xmlrpc->send_response($response);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}
-</code>
-
-<h3>Notes:</h3>
-<p>The <dfn>output_parameters()</dfn> function retrieves an indexed array corresponding to the request parameters sent by the client.
-In the above example, the output parameters will be the username and password.</p>
-
-<p>If the username and password sent by the client were not valid, and error message is returned using <dfn>send_error_message()</dfn>.</p>
-
-<p>If the operation was successful, the client will be sent back a response array containing the user's info.</p>
-
-
-<h2>Formatting a Response</h2>
-
-<p>Similar to <em>Requests</em>, <em>Responses</em> must be formatted as an array.  However, unlike requests, a response is an array
-<strong>that contains a single item</strong>.  This item can be an array with several additional arrays, but there
-can be only one primary array index.  In other words, the basic prototype is this:</p>
-
-<code>$response = array('Response data',  'array');</code>
-
-<p>Responses, however, usually contain multiple pieces of information. In order to accomplish this we must put the response into its own
-array so that the primary array continues to contain a single piece of data.  Here's an example showing how this might be accomplished:</p>
-
-<code>
-$response = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'first_name' => array('John', 'string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'last_name' => array('Doe', 'string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'member_id' => array(123435, 'int'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'todo_list' => array(array('clean house', 'call mom', 'water plants'), 'array'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'struct'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);
-</code>
-
-<p class="important">Notice that the above array is formatted as a <dfn>struct</dfn>.  This is the most common data type for responses.</p>
-
-<p>As with Requests, a response can be one of the seven data types listed in the  <a href="#datatypes">Data Types</a>  section.</p>
-
-
-<h2>Sending an Error Response</h2>
-
-<p>If you need to send the client an error response you will use the following:</p>
-
-<code>return $this->xmlrpc->send_error_message('123', 'Requested data not available');</code>
-
-<p>The first parameter is the error number while the second parameter is the error message.</p>
-
-
-
-
-
-
-<h2>Creating Your Own Client and Server</h2>
-
-<p>To help you understand everything we've covered thus far, let's create a couple controllers that act as
-XML-RPC Client and Server.  You'll use the Client to send a request to the Server and receive a response.</p>
-
-<h3>The Client</h3>
-
-<p>Using a text editor, create a controller called <dfn>xmlrpc_client.php</dfn>.
-In it, place this code and save it to your <samp>applications/controllers/</samp> folder:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="32">&lt;?php
-
-class Xmlrpc_client extends CI_Controller {
-
-	function index()
-	{
-		$this->load->helper('url');
-		$server_url = site_url('xmlrpc_server');
-
-		$this->load->library('xmlrpc');
-
-		$this->xmlrpc->server($server_url, 80);
-		$this->xmlrpc->method('Greetings');
-
-		$request = array('How is it going?');
-		$this->xmlrpc->request($request);
-
-		if ( ! $this->xmlrpc->send_request())
-		{
-			echo $this->xmlrpc->display_error();
-		}
-		else
-		{
-			echo '<pre>';
-			print_r($this->xmlrpc->display_response());
-			echo '</pre>';
-		}
-	}
-}
-?></textarea>
-
-<p>Note: In the above code we are using a "url helper".  You can find more information in the <a href="../general/helpers.html">Helpers Functions</a> page.</p>
-
-<h3>The Server</h3>
-
-<p>Using a text editor, create a controller called <dfn>xmlrpc_server.php</dfn>.
-In it, place this code and save it to your <samp>applications/controllers/</samp> folder:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="30">&lt;?php
-
-class Xmlrpc_server extends CI_Controller {
-
-	function index()
-	{
-		$this->load->library('xmlrpc');
-		$this->load->library('xmlrpcs');
-
-		$config['functions']['Greetings'] = array('function' => 'Xmlrpc_server.process');
-
-		$this->xmlrpcs->initialize($config);
-		$this->xmlrpcs->serve();
-	}
-
-
-	function process($request)
-	{
-		$parameters = $request->output_parameters();
-

-<h3>Try it!</h3>
-
-<p>Now visit the your site using a URL similar to this:</p>
-<code>example.com/index.php/<var>xmlrpc_client</var>/</code>
-
-<p>You should now see the message you sent to the server, and its response back to you.</p>
-
-<p>The client you created sends a message ("How's is going?") to the server, along with a request for the "Greetings" method.
-The Server receives the request and maps it to the "process" function, where a response is sent back.</p>
-
-<h2>Using Associative Arrays In a Request Parameter</h2>
-
-<p>If you wish to use an associative array in your method parameters you will need to use a struct datatype:</p>
-
-<code>$request = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Param 0<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />

-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Param 1<br />

-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-	$this-&gt;xmlrpc-&gt;request($request);</code>
-
-<p>You can retrieve the associative array when processing the request in the Server.</p>
-
-<code>$parameters = $request-&gt;output_parameters();<br />
-	$name = $parameters['0']['name'];<br />
-	$size = $parameters['1']['size'];<br />
-	$size = $parameters['1']['shape']; </code>
-

-<h1>Zip Encoding Class</h1>
-<p>CodeIgniter's Zip Encoding Class classes permit you to create Zip archives. Archives can be downloaded to your
-desktop or saved to a directory.</p>
-
-
-<h2>Initializing the Class</h2>
-<p>Like most other classes in CodeIgniter, the Zip class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('zip');</code>
-<p>Once loaded, the Zip library object will be available using: <dfn>$this->zip</dfn></p>
-
-
-<h2>Usage Example</h2>
-
-<p>This example demonstrates how to compress a file, save it to a folder on your server, and download it to your desktop.</p>
-
-<code>
-$name = 'mydata1.txt';<br />
-$data = 'A Data String!';<br />
-<br />
-$this->zip->add_data($name, $data);<br />
-<br />
-// Write the zip file to a folder on your server. Name it "my_backup.zip"<br />
-$this->zip->archive('/path/to/directory/my_backup.zip');
-<br /><br />
- // Download the file to your desktop.  Name it "my_backup.zip"<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<h1>Function Reference</h1>
-
-<h2>$this->zip->add_data()</h2>
-
-<p>Permits you to add data to the Zip archive. The first parameter must contain the name you would like
-given to the file, the second parameter must contain the file data as a string:</p>
-
-<code>
-$name = 'my_bio.txt';<br />
-$data = 'I was born in an elevator...';<br />
-<br />
-$this->zip->add_data($name, $data);
-</code>
-
-<p>You are allowed multiple calls to this function in order to
-add several files to your archive.  Example:</p>
-
-<code>
-$name = 'mydata1.txt';<br />
-$data = 'A Data String!';<br />
-$this->zip->add_data($name, $data);<br />
-<br />
-$name = 'mydata2.txt';<br />
-$data = 'Another Data String!';<br />
-$this->zip->add_data($name, $data);<br />
-</code>
-
-<p>Or you can pass multiple files using an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'mydata1.txt' => 'A Data String!',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'mydata2.txt' => 'Another Data String!'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->zip->add_data($data);<br />
-<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<p>If you would like your compressed data organized into sub-folders, include the path as part of the filename:</p>
-
-<code>
-$name = '<kbd>personal/</kbd>my_bio.txt';<br />
-$data = 'I was born in an elevator...';<br />
-<br />
-$this->zip->add_data($name, $data);
-</code>
-
-<p>The above example will place <dfn>my_bio.txt</dfn> inside a folder called <kbd>personal</kbd>.</p>
-
-
-<h2>$this->zip->add_dir()</h2>
-
-<p>Permits you to add a directory.  Usually this function is unnecessary since you can place your data into folders when
-using <dfn>$this->zip->add_data()</dfn>, but if you would like to create an empty folder you can do so.  Example:</p>
-
-<code>$this->zip->add_dir('myfolder'); // Creates a folder called "myfolder"</code>
-
-
-
-<h2>$this->zip->read_file()</h2>
-
-<p>Permits you to compress a file that already exists somewhere on your server.  Supply a file path and the zip class will
-read it and add it to the archive:</p>
-
-<code>
-$path = '/path/to/photo.jpg';<br /><br />
-$this->zip->read_file($path);
-<br /><br />
- // Download the file to your desktop.  Name it "my_backup.zip"<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<p>If you would like the Zip archive to maintain the directory structure of the file in it, pass <kbd>TRUE</kbd> (boolean) in the
-second parameter.  Example:</p>
-
-
-<code>
-$path = '/path/to/photo.jpg';<br /><br />
-$this->zip->read_file($path, <kbd>TRUE</kbd>);
-<br /><br />
- // Download the file to your desktop.  Name it "my_backup.zip"<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<p>In the above example, <dfn>photo.jpg</dfn> will be placed inside two folders:  <kbd>path/to/</kbd></p>
-
-
-
-<h2>$this->zip->read_dir()</h2>
-
-<p>Permits you to compress a folder (and its contents) that already exists somewhere on your server.  Supply a file path to the
-directory and the zip class will recursively read it and recreate it as a Zip archive.  All files contained within the
-supplied path will be encoded, as will any sub-folders contained within it.  Example:</p>
-
-<code>
-$path = '/path/to/your/directory/';<br /><br />
-$this->zip->read_dir($path);
-<br /><br />
- // Download the file to your desktop.  Name it "my_backup.zip"<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<p>By default the Zip archive will place all directories listed in the first parameter inside the zip. If you want the tree preceding the target folder to be ignored
-you can pass <kbd>FALSE</kbd> (boolean) in the second parameter.  Example:</p>
-
-<code>
-$path = '/path/to/your/directory/';<br /><br />
-$this->zip->read_dir($path, FALSE);
-</code>
-
-<p>This will create a ZIP with the folder "directory" inside, then all sub-folders stored correctly inside that, but will not include the folders <samp>/path/to/your</samp>.</p>
-
-
-
-
-<h2>$this->zip->archive()</h2>
-
-<p>Writes the Zip-encoded file to a directory on your server.  Submit a valid server path ending in the file name.  Make sure the
-directory is writable (666 or 777 is usually OK). Example:</p>
-
-<code>$this->zip->archive('/path/to/folder/myarchive.zip'); // Creates a file named myarchive.zip</code>
-
-
-<h2>$this->zip->download()</h2>
-
-<p>Causes the Zip file to be downloaded from your server. The function must be passed the name you would like the zip file called.
-Example:</p>
-
-<code>$this->zip->download('latest_stuff.zip'); // File will be named "latest_stuff.zip"</code>
-
-<p class="important"><strong>Note:</strong>&nbsp; Do not display any data in the controller in which you call this function since it sends various server headers
-that cause the download to happen and the file to be treated as binary.</p>
-
-
-<h2>$this->zip->get_zip()</h2>
-
-<p>Returns the Zip-compressed file data.  Generally you will not need this function unless you want to do something unique with the data.
-Example:</p>
-
-<code>
-$name = 'my_bio.txt';<br />
-$data = 'I was born in an elevator...';<br />
-<br />
-$this->zip->add_data($name, $data);<br /><br />
-
-$zip_file = $this->zip->get_zip();
-</code>
-
-
-<h2>$this->zip->clear_data()</h2>
-
-<p>The Zip class caches your zip data so that it doesn't need to recompile the Zip archive for each function you use above.
-If, however, you need to create multiple Zips, each with different data, you can clear the cache between calls. Example:</p>
-
-<code>
-$name = 'my_bio.txt';<br />
-$data = 'I was born in an elevator...';<br />
-<br />
-$this->zip->add_data($name, $data);<br />
-$zip_file = $this->zip->get_zip();<br />
-<br />
-<kbd>$this->zip->clear_data();</kbd>
-<br /><br />
-
-$name = 'photo.jpg';<br />
-$this->zip->read_file("/path/to/photo.jpg"); // Read the file's contents<br />
-<br /><br />
-$this->zip->download('myphotos.zip');
-</code>

-<li>The Router examines the HTTP request to determine what should be done with it.</li>
-<li>If a cache file exists, it is sent directly to the browser, bypassing the normal system execution.</li>
-<li>Security.  Before the application controller is loaded, the HTTP request and any user submitted data is filtered for security.</li>
-<li>The Controller loads the model, core libraries, helpers, and any other resources needed to process the specific request.</li>
-<li>The finalized View is rendered then sent to the web browser to be seen. If caching is enabled, the view is cached first so
-that on subsequent requests it can be served.</li>

-<h1>CodeIgniter at a Glance</h1>
-
-
-<h2>CodeIgniter is an Application Framework</h2>
-
-<p>CodeIgniter is a toolkit for people who build web applications using PHP.  Its goal is to enable you to develop projects much faster than you could if you were writing code
-from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and
-logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by
-minimizing the amount of code needed for a given task.</p>
-
-<h2>CodeIgniter is Free</h2>
-<p>CodeIgniter is licensed under an Apache/BSD-style open source license so you can use it however you please.
-For more information please read the <a href="../license.html">license agreement</a>.</p>
-
-<h2>CodeIgniter is Light Weight</h2>
-<p>Truly light weight.  The core system requires only a few very small libraries. This is in stark contrast to many frameworks that require significantly more resources.
-Additional libraries are loaded dynamically upon request, based on your needs for a given process, so the base system
-is very lean and quite fast.
-</p>
-
-<h2>CodeIgniter is Fast</h2>
-<p>Really fast. We challenge you to find a framework that has better performance than CodeIgniter.</p>
-
-
-<h2>CodeIgniter Uses M-V-C</h2>
-<p>CodeIgniter uses the Model-View-Controller approach, which allows great separation between logic and presentation.
-This is particularly good for projects in which designers are working with your template files, as the code these file contain will be minimized. We describe MVC in more detail on its own page.</p>
-
-<h2>CodeIgniter Generates Clean URLs</h2>
-<p>The URLs generated by CodeIgniter are clean and search-engine friendly.  Rather than using the standard "query string"
-approach to URLs that is synonymous with dynamic systems, CodeIgniter uses a segment-based approach:</p>
-
-<code>example.com/<var>news</var>/<dfn>article</dfn>/<samp>345</samp></code>
-
-<p>Note: By default the index.php file is included in the URL but it can be removed using a simple .htaccess file.</p>
-
-<h2>CodeIgniter Packs a Punch</h2>
-<p>CodeIgniter comes with  full-range of libraries that enable the most commonly needed web development tasks,
-like accessing a database, sending email, validating form data, maintaining sessions, manipulating images, working with XML-RPC data and
-much more.</p>
-
-<h2>CodeIgniter is Extensible</h2>
-<p>The system can be easily extended through the use of your own libraries, helpers, or through class extensions or system hooks.</p>
-
-
-<h2>CodeIgniter Does Not Require a Template Engine</h2>
-<p>Although CodeIgniter <em>does</em> come with a simple template parser that can be optionally used, it does not force you to use one.
-
-Template engines simply can not match the performance of native PHP, and the syntax that must be learned to use a template
-engine is usually only marginally easier than learning the basics of PHP.  Consider this block of PHP code:</p>
-
-<code>&lt;ul><br />
-<br />
-&lt;?php foreach ($addressbook as $name):?><br />
-<br />
-&lt;li>&lt;?=$name?>&lt;/li><br />
-<br />
-&lt;?php endforeach; ?><br />
-<br />
-&lt;/ul></code>
-
-<p>Contrast this with the pseudo-code used by a template engine:</p>
-
-<code>&lt;ul><br />
-<br />
-{foreach from=$addressbook item="name"}<br />
-<br />
-&lt;li>{$name}&lt;/li><br />
-<br />
-{/foreach}<br />
-<br />
-&lt;/ul></code>
-
-<p>Yes, the template engine example is a bit cleaner, but it comes at the price of performance, as the pseudo-code must be converted
-back into PHP to run. Since one of our goals is <em>maximum performance</em>, we opted to not require the use of a template engine.</p>
-
-
-<h2>CodeIgniter is Thoroughly Documented</h2>
-<p>Programmers love to code and hate to write documentation.  We're no different, of course, but
-since documentation is <strong>as important</strong> as the code itself,
-we are committed to doing it. Our source code is extremely clean and well commented as well.</p>
-
-
-<h2>CodeIgniter has a Friendly Community of Users</h2>
-
-<p>Our growing community of users can be seen actively participating in our <a href="http://codeigniter.com/forums/">Community Forums</a>.</p>

-<h1>CodeIgniter Features</h1>
-
-<p>Features in and of themselves are a very poor way to judge an application since they tell you nothing
-about the user experience, or how intuitively or intelligently it is designed.  Features
-don't reveal anything about the quality of the code, or the performance, or the attention to detail, or security practices.
-The only way to really judge an app is to try it and get to know the code. <a href="../installation/">Installing</a>
-CodeIgniter is child's play so we encourage you to do just that.  In the mean time here's a list of CodeIgniter's main features.</p>
-
-<ul>
-<li>Model-View-Controller Based System</li>
-<li>Extremely Light Weight</li>
-<li>Full Featured database classes with support for several platforms.</li>
-<li>Active Record Database Support</li>
-<li>Form and Data Validation</li>
-<li>Security and XSS Filtering</li>
-<li>Session Management</li>
-<li>Email Sending Class. Supports Attachments, HTML/Text email, multiple protocols (sendmail, SMTP, and Mail) and more.</li>
-<li>Image Manipulation Library (cropping, resizing, rotating, etc.).  Supports GD, ImageMagick, and NetPBM</li>
-<li>File Uploading Class</li>
-<li>FTP Class</li>
-<li>Localization</li>
-<li>Pagination</li>
-<li>Data Encryption</li>
-<li>Benchmarking</li>
-<li>Full Page Caching</li>
-<li>Error Logging</li>
-<li>Application Profiling</li>
-<li>Calendaring Class</li>
-<li>User Agent Class</li>
-<li>Zip Encoding Class</li>

-<h2>Design and Architectural Goals</h2>
-
-<p>Our goal for CodeIgniter is <dfn>maximum performance, capability, and flexibility in the smallest, lightest possible package</dfn>.</p>
-
-<p>To meet this goal we are committed to benchmarking, re-factoring, and simplifying at every step of the development process,
-rejecting anything that doesn't further the stated objective.</p>
-
-<p>From a technical and architectural standpoint, CodeIgniter was created with the following objectives:</p>
-
-<ul>
-<li><strong>Dynamic Instantiation.</strong>  In CodeIgniter, components are loaded and routines executed only when requested, rather than globally.  No assumptions are made by the system regarding what may be needed beyond the minimal core resources, so the system is very light-weight by default.  The events, as triggered by the HTTP request, and the controllers and views you design will determine what is invoked.</li>
-<li><strong>Loose Coupling.</strong>  Coupling is the degree to which components of a system rely on each other.  The less components depend on each other the more reusable and flexible the system becomes. Our goal was a very loosely coupled system.</li>
-<li><strong>Component Singularity.</strong>  Singularity is the degree to which components have a narrowly focused purpose.  In CodeIgniter, each class and its functions are highly autonomous in order to allow maximum usefulness.</li>
-</ul>
-
-<p>CodeIgniter is a dynamically instantiated, loosely coupled system with high component singularity. It strives for simplicity, flexibility, and high performance in a small footprint package.</p>

-<h1>Model-View-Controller</h1>
-
-<p>CodeIgniter is based on the Model-View-Controller development pattern.
-
-MVC is a software approach that separates application logic from presentation.  In practice, it permits your web pages to contain minimal scripting since the presentation is separate from the PHP scripting.</p>
-
-<ul>
-<li>The <strong>Model</strong> represents your data structures. Typically your model classes will contain functions that help you
-retrieve, insert, and update information in your  database.</li>
-<li>The <strong>View</strong> is the information that is being presented to a user.  A View will normally be a web page, but
-in CodeIgniter, a view can also be a page fragment like a header or footer. It can also be an RSS page, or any other type of "page".</li>
-<li>The <strong>Controller</strong> serves as an <em>intermediary</em> between the Model, the View,
-and any other resources needed to process the HTTP request and generate a web page.</li>
-
-</ul>
-
-<p>CodeIgniter has a fairly loose approach to MVC since Models are not required.
-If you don't need the added separation, or find that maintaining models requires more complexity than you
-want, you can ignore them and build your application minimally using Controllers and Views. CodeIgniter also
-enables you to incorporate your own existing scripts, or even develop core libraries for the system,
- enabling you to work in a way that makes the most sense to you.</p>

+CodeIgniter User Guide
+######################
+
+******************
+Setup Instructions
+******************
+
+The CodeIgniter user guide uses Sphinx to manage the documentation and
+output it to various formats.  Pages are written in human-readable
+`ReStructured Text <http://sphinx.pocoo.org/rest.html>`_ format.
+
+Prerequisites
+=============
+
+Sphinx requires Python, which is already installed if you are running OS X.
+You can confirm in a Terminal window by executing the ``python`` command
+without any parameters.  It should load up and tell you which version you have
+installed.  If you're not on 2.7+, go ahead and install 2.7.2 from
+http://python.org/download/releases/2.7.2/
+
+Installation
+============
+
+1. Install `easy_install <http://peak.telecommunity.com/DevCenter/EasyInstall#installing-easy-install>`_
+2. ``easy_install sphinx``
+3. ``easy_install sphinxcontrib-phpdomain``
+4. Install the CI Lexer which allows PHP, HTML, CSS, and JavaScript syntax highlighting in code examples (see *cilexer/README*)
+5. ``cd user_guide_src``
+6. ``make html``
+
+Editing and Creating Documentation
+==================================
+
+All of the source files exist under *source/* and is where you will add new
+documentation or modify existing documentation.  Just as with code changes,
+we recommend working from feature branches and making pull requests to
+the *develop* branch of this repo.
+
+So where's the HTML?
+====================
+
+Obviously, the HTML documentation is what we care most about, as it is the
+primary documentation that our users encounter.  Since revisions to the built
+files are not of value, they are not under source control.  This also allows
+you to regenerate as necessary if you want to "preview" your work.  Generating
+the HTML is very simple.  From the root directory of your user guide repo
+fork issue the command you used at the end of the installation instructions::
+
+	make html
+
+You will see it do a whiz-bang compilation, at which point the fully rendered
+user guide and images will be in *build/html/*.  After the HTML has been built,
+each successive build will only rebuild files that have changed, saving
+considerable time.  If for any reason you want to "reset" your build files,
+simply delete the *build* folder's contents and rebuild.
+
+***************
+Style Guideline
+***************
+
+Please refer to source/documentation/index.rst for general guidelines for
+using Sphinx to document CodeIgniter.

+To install the CodeIgniter Lexer to Pygments, run:
+
+	sudo python setup.py install
+
+Confirm with
+
+	pygmentize -L
+	
+
+You should see in the lexer output:
+
+* ci, codeigniter:
+    CodeIgniter (filenames *.html, *.css, *.php, *.xml, *.static)
+
+You will need to run setup.py and install the cilexer package anytime after cilexer/cilexer.py is updated
+
+NOTE: Depending on how you installed Sphinx and Pygments,
+you may be installing to the wrong version. 
+If you need to install to a different version of python
+specify its path when using setup.py, e.g.:
+
+	sudo /usr/bin/python2.5 setup.py install

+
+Version 2.0.3
+=============
+
+Release Date: August 20, 2011
+
+-  Security
+
+   -  An improvement was made to the MySQL and MySQLi drivers to prevent
+      exposing a potential vector for SQL injection on sites using
+      multi-byte character sets in the database client connection.
+      An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
+      *mysql_set_charset()* creates a situation where using multi-byte
+      character sets on these environments may potentially expose a SQL
+      injection attack vector. Latin-1, UTF-8, and other "low ASCII"
+      character sets are unaffected on all environments.
+
+      If you are running or considering running a multi-byte character
+      set for your database connection, please pay close attention to
+      the server environment you are deploying on to ensure you are not
+      vulnerable.
+
+-  General Changes
+
+   -  Fixed a bug where there was a misspelling within a code comment in
+      the index.php file.

+      added a show/hide toggle on HTTP Headers, Session Data and Config
+      Variables.
+   -  Removed internal usage of the EXT constant.

+      templates. Thanks to `danijelb <https://bitbucket.org/danijelb>`_
+      for the pull request.
+   -  Added insert_batch() function to the PostgreSQL database driver.
+      Thanks to epallerols for the patch.
+   -  Added "application/x-csv" to mimes.php.
+   -  Added CSRF protection URI whitelisting.
+   -  Fixed a bug where `Email library <libraries/email>`
+      attachments with a "." in the name would using invalid MIME-types.
+   -  Added support for
+      pem,p10,p12,p7a,p7c,p7m,p7r,p7s,crt,crl,der,kdb,rsa,cer,sst,csr
+      Certs to mimes.php.

+      helper <helpers/inflector_helper>` to support considerably
+      more words.

+      string. See upgrade notes if using database sessions.
+   -  Added $this->db->set_dbprefix() to the :doc:`Database
+      Driver <database/queries>`.
+   -  Changed $this->cart->insert() in the :doc:`Cart

+      item was inserted successfully.
+   -  Added $this->load->get_var() to the :doc:`Loader
+      library <libraries/loader>` to retrieve global vars set with
+      $this->load->view() and $this->load->vars().
+   -  Changed $this->db->having() to insert quotes using escape() rather

+   space between it and the opening tag.
+-  Fixed a bug where the method $this->cart->total_items() from :doc:`Cart
+   Library <libraries/cart>` now returns the sum of the quantity
+   of all items in the cart instead of your total count.
+-  Fixed a bug where not setting 'null' when adding fields in db_forge
+   for mysql and mysqli drivers would default to NULL instead of NOT
+   NULL as the docs suggest.
+-  Fixed a bug where using $this->db->select_max(),
+   $this->db->select_min(), etc could throw notices. Thanks to w43l for
+   the patch.
+-  Replace checks for STDIN with php_sapi_name() == 'cli' which on the
+   whole is more reliable. This should get parameters in crontab
+   working.

+   -  Added support for
+      :ref:`environment-specific <config-environments>`
+      configuration files.

+
+Version 2.0.0
+=============
+
+Release Date: January 28, 2011
+Hg Tag: v2.0.0
+
+-  General changes
+
+   -  PHP 4 support is removed. CodeIgniter now requires PHP 5.1.6.
+   -  Scaffolding, having been deprecated for a number of versions, has
+      been removed.
+   -  Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
+      has been converted to a Helper and
+      :doc:`documented <./helpers/captcha_helper>`. The JavaScript
+      calendar plugin was removed due to the ready availability of great
+      JavaScript calendars, particularly with jQuery.
+   -  Added new special Library type:
+      :doc:`Drivers <./general/drivers>`.
+   -  Added full query-string support. See the config file for details.
+   -  Moved the application folder outside of the system folder.
+   -  Moved system/cache and system/logs directories to the application
+      directory.
+   -  Added routing overrides to the main index.php file, enabling the
+      normal routing to be overridden on a per "index" file basis.
+   -  Added the ability to set config values (or override config values)
+      directly from data set in the main index.php file. This allows a
+      single application to be used with multiple front controllers,
+      each having its own config values.
+   -  Added $config['directory_trigger'] to the config file so that a
+      controller sub-directory can be specified when running _GET
+      strings instead of URI segments.
+   -  Added ability to set "Package" paths - specific paths where the
+      Loader and Config classes should try to look first for a requested
+      file. This allows distribution of sub-applications with their own
+      libraries, models, config files, etc. in a single "package"
+      directory. See the :doc:`Loader class <libraries/loader>`
+      documentation for more details.
+   -  In-development code is now hosted at
+      `BitBucket <http://bitbucket.org/ellislab/codeigniter-reactor/>`_.
+   -  Removed the deprecated Validation Class.
+   -  Added CI\_ Prefix to all core classes.
+   -  Package paths can now be set in application/config/autoload.php.
+   -  `Upload library <libraries/file_uploading>` file_name can
+      now be set without an extension, the extension will be taken from
+      the uploaded file instead of the given name.
+   -  In :doc:`Database Forge <database/forge>` the name can be omitted
+      from $this->dbforge->modify_column()'s 2nd param if you aren't
+      changing the name.
+   -  $config['base_url'] is now empty by default and will guess what
+      it should be.
+   -  Enabled full Command Line Interface compatibility with
+      config['uri_protocol'] = 'CLI';.
+
+-  Libraries
+
+   -  Added a :doc:`Cache driver <libraries/caching>` with APC,
+      memcached, and file-based support.
+   -  Added $prefix, $suffix and $first_url properties to :doc:`Pagination
+      library <./libraries/pagination>`.
+   -  Added the ability to suppress first, previous, next, last, and
+      page links by setting their values to FALSE in the :doc:`Pagination
+      library <./libraries/pagination>`.
+   -  Added :doc:`Security library <./libraries/security>`, which now
+      contains the xss_clean function, filename_security function and
+      other security related functions.
+   -  Added CSRF (Cross-site Reference Forgery) protection to the
+      :doc:`Security library <./libraries/security>`.
+   -  Added $parse_exec_vars property to Output library.
+   -  Added ability to enable / disable individual sections of the
+      :doc:`Profiler <general/profiling>`
+   -  Added a wildcard option $config['allowed_types'] = '\*' to the
+      :doc:`File Uploading Class <./libraries/file_uploading>`.
+   -  Added an 'object' config variable to the XML-RPC Server library so
+      that one can specify the object to look for requested methods,
+      instead of assuming it is in the $CI superobject.
+   -  Added "is_object" into the list of unit tests capable of being
+      run.
+   -  Table library will generate an empty cell with a blank string, or
+      NULL value.
+   -  Added ability to set tag attributes for individual cells in the
+      Table library
+   -  Added a parse_string() method to the :doc:`Parser

+
+   -  Added an optional second parameter to show_404() to disable

+      content-length headers if the server runs with
+      zlib.output_compression enabled.
+   -  Eliminated a call to is_really_writable() on each request unless
+      it is really needed (Output caching)
+   -  Documented append_output() in the :doc:`Output
+      Class <libraries/output>`.
+   -  Documented a second argument in the decode() function for the

+Version 1.7
+===========
+
+Release Date: October 23, 2008
+Hg Tag: 1.7.0
+
+-  Libraries
+
+   -  Added a new :doc:`Form Validation
+      Class <libraries/form_validation>`. It simplifies setting
+      rules and field names, supports arrays as field names, allows
+      groups of validation rules to be saved in a config file, and adds
+      some helper functions for use in view files. **Please note that
+      the old Validation class is now deprecated**. We will leave it in
+      the library folder for some time so that existing applications
+      that use it will not break, but you are encouraged to migrate to
+      the new version.
+   -  Updated the :doc:`Sessions class <libraries/sessions>` so that
+      any custom data being saved gets stored to a database rather than
+      the session cookie (assuming you are using a database to store
+      session data), permitting much more data to be saved.
+   -  Added the ability to store libraries in subdirectories within
+      either the main "libraries" or the local application "libraries"
+      folder. Please see the :doc:`Loader class <libraries/loader>` for
+      more info.
+   -  Added the ability to assign library objects to your own variable
+      names when you use $this->load->library(). Please see the :doc:`Loader
+      class <libraries/loader>` for more info.
+   -  Added controller class/method info to :doc:`Profiler
+      class <general/profiling>` and support for multiple database
+      connections.
+   -  Improved the "auto typography" feature and moved it out of the
+      helper into its own :doc:`Typography
+      Class <libraries/typography>`.
+   -  Improved performance and accuracy of xss_clean(), including
+      reduction of false positives on image/file tests.
+   -  Improved :doc:`Parser class <./libraries/parser>` to allow
+      multiple calls to the parse() function. The output of each is
+      appended in the output.
+   -  Added max_filename option to set a file name length limit in the
+      :doc:`File Upload Class <libraries/file_uploading>`.
+   -  Added set_status_header() function to :doc:`Output
+      class <libraries/output>`.
+   -  Modified :doc:`Pagination <libraries/pagination>` class to only
+      output the "First" link when the link for page one would not be
+      shown.
+   -  Added support for mb_strlen in the :doc:`Form
+      Validation <libraries/form_validation>` class so that
+      multi-byte languages will calculate string lengths properly.
+
+-  Database
+
+   -  Improved Active Record class to allow full path column and table
+      names: hostname.database.table.column. Also improved the alias
+      handling.
+   -  Improved how table and column names are escaped and prefixed. It
+      now honors full path names when adding prefixes and escaping.
+   -  Added Active Record caching feature to "update" and "delete"
+      functions.
+   -  Added removal of non-printing control characters in escape_str()
+      of DB drivers that do not have native PHP escaping mechanisms
+      (mssql, oci8, odbc), to avoid potential SQL errors, and possible
+      sources of SQL injection.
+   -  Added port support to MySQL, MySQLi, and MS SQL database drivers.
+   -  Added driver name variable in each DB driver, based on bug report
+      #4436.
+
+-  Helpers
+
+   -  Added several new "setting" functions to the :doc:`Form
+      helper <helpers/form_helper>` that allow POST data to be
+      retrieved and set into forms. These are intended to be used on
+      their own, or with the new :doc:`Form Validation
+      Class <libraries/form_validation>`.

+   batches of email.
+-  Deprecated the application/scripts folder. It will continue to work
+   for legacy users, but it is recommended that you create your own
+   :doc:`libraries <./general/libraries>` or
+   :doc:`models <./general/models>` instead. It was originally added
+   before CI had user libraries or models, but it's not needed anymore.
+-  Deprecated the $autoload['core'] item from the autoload.php file.
+   Instead, please now use: $autoload['libraries']

+-  Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
+-  Added the ability to pass objects to the **insert()** and
+   **update()** database functions. This feature enables you to (among
+   other things) use your :doc:`Model class <./general/models>`
+   variables to run queries with. See the Models page for details.
+-  Added the ability to pass objects to the :doc:`view loading
+   function <./general/views>`: $this->load->view('my_view',
+   $object);
+-  Added getwhere function to :doc:`Active Record
+   class <./database/active_record>`.
+-  Added count_all function to :doc:`Active Record
+   class <./database/active_record>`.
+-  Added language file for scaffolding and fixed a scaffolding bug that
+   occurs when there are no rows in the specified table.
+-  Added :doc:`$this->db->last_query() <./database/queries>`, which
+   allows you to view your last query that was run.
+-  Added a new mime type to the upload class for better compatibility.
+-  Changed how cache files are read to prevent PHP errors if the cache
+   file contains an XML tag, which PHP wants to interpret as a short
+   tag.
+-  Fixed a bug in a couple of the active record functions (where and
+   orderby).
+-  Fixed a bug in the image library when realpath() returns false.
+-  Fixed a bug in the Models that was preventing libraries from being
+   used within them.
+-  Fixed a bug in the "exact_length" function of the validation class.
+-  Fixed some typos in the user guide
+
+Version 1.3
+===========
+
+Release Date: April 3, 2006
+
+-  Added support for :doc:`Models <general/models>`.
+-  Redesigned the database libraries to support additional RDBMs
+   (Postgres, MySQLi, etc.).
+-  Redesigned the :doc:`Active Record class <./database/active_record>`
+   to enable more varied types of queries with simpler syntax, and
+   advanced features like JOINs.
+-  Added a feature to the database class that lets you run :doc:`custom
+   function calls <./database/call_function>`.
+-  Added support for :doc:`private functions <general/controllers>` in your
+   controllers. Any controller function name that starts with an
+   underscore will not be served by a URI request.
+-  Added the ability to pass your own initialization parameters to your
+   :doc:`custom core libraries <general/creating_libraries>` when using
+   $this->load->library()
+-  Added support for running standard :doc:`query string URLs <general/urls>`.
+   These can be optionally enabled in your config file.
+-  Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
+   appended to your URLs. For example, you could add .html to your URLs,
+   making them appear static. This feature is enabled in your config
+   file.
+-  Added a new error template for use with native PHP errors.
+-  Added "alternator" function in the :doc:`string
+   helpers <./helpers/string_helper>`.
+-  Removed slashing from the input class. After much debate we decided
+   to kill this feature.
+-  Change the commenting style in the scripts to the PEAR standard so
+   that IDEs and tools like phpDocumenter can harvest the comments.
+-  Added better class and function name-spacing to avoid collisions with
+   user developed classes. All CodeIgniter classes are now prefixed with
+   CI\_ and all controller methods are prefixed with _ci to avoid
+   controller collisions. A list of reserved function names can be
+   :doc:`found here <general/controllers>`.
+-  Redesigned how the "CI" super object is referenced, depending on
+   whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
+   way to manage objects that utilizes a bit less resources.
+-  Deprecated: $this->db->use_table() has been deprecated. Please read
+   the :doc:`Active Record <./database/active_record>` page for
+   information.
+-  Deprecated: $this->db->smart_escape_str() has been deprecated.
+   Please use this instead: $this->db->escape()
+-  Fixed a bug in the exception handler which was preventing some PHP
+   errors from showing up.
+-  Fixed a typo in the URI class. $this->total_segment() should be
+   plural: $this->total_segments()
+-  Fixed some typos in the default calendar template
+-  Fixed some typos in the user guide
+
+Version 1.2
+===========
+
+Release Date: March 21, 2006
+
+-  Redesigned some internal aspects of the framework to resolve scoping
+   problems that surfaced during the beta tests. The problem was most
+   notable when instantiating classes in your constructors, particularly
+   if those classes in turn did work in their constructors.
+-  Added a global function named
+   :doc:`get_instance() <general/ancillary_classes>` allowing the main
+   CodeIgniter object to be accessible throughout your own classes.
+-  Added new :doc:`File Helper <./helpers/file_helper>`:
+   delete_files()
+-  Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
+   index_page()
+-  Added the ability to create your own :doc:`core
+   libraries <general/creating_libraries>` and store them in your local
+   application directory.
+-  Added an overwrite option to the :doc:`Upload
+   class <./libraries/file_uploading>`, enabling files to be
+   overwritten rather than having the file name appended.
+-  Added Javascript Calendar plugin.
+-  Added search feature to user guide. Note: This is done using Google,
+   which at the time of this writing has not crawled all the pages of
+   the docs.
+-  Updated the parser class so that it allows tag pars within other tag
+   pairs.
+-  Fixed a bug in the DB "where" function.
+-  Fixed a bug that was preventing custom config files to be
+   auto-loaded.
+-  Fixed a bug in the mysql class bind feature that prevented question
+   marks in the replacement data.
+-  Fixed some bugs in the xss_clean function
+
+Version Beta 1.1
+================
+
+Release Date: March 10, 2006
+
+-  Added a :doc:`Calendaring class <./libraries/calendar>`.
+-  Added support for running :doc:`multiple
+   applications <general/managing_apps>` that share a common CodeIgniter
+   backend.
+-  Moved the "uri protocol" variable from the index.php file into the
+   config.php file
+-  Fixed a problem that was preventing certain function calls from
+   working within constructors.
+-  Fixed a problem that was preventing the $this->load->library function
+   from working in constructors.
+-  Fixed a bug that occurred when the session class was loaded using the
+   auto-load routine.
+-  Fixed a bug that can happen with PHP versions that do not support the
+   E_STRICT constant
+-  Fixed a data type error in the form_radio function (form helper)
+-  Fixed a bug that was preventing the xss_clean function from being
+   called from the validation class.
+-  Fixed the cookie related config names, which were incorrectly
+   specified as $conf rather than $config
+-  Fixed a pagination problem in the scaffolding.
+-  Fixed a bug in the mysql class "where" function.
+-  Fixed a regex problem in some code that trimmed duplicate slashes.
+-  Fixed a bug in the br() function in the HTML helper
+-  Fixed a syntax mistake in the form_dropdown function in the Form
+   Helper.
+-  Removed the "style" attributes form the form helpers.
+-  Updated the documentation. Added "next/previous" links to each page
+   and fixed various typos.

+###################
+Active Record Class
+###################
+
+CodeIgniter uses a modified version of the Active Record Database
+Pattern. This pattern allows information to be retrieved, inserted, and
+updated in your database with minimal scripting. In some cases only one
+or two lines of code are necessary to perform a database action.
+CodeIgniter does not require that each database table be its own class
+file. It instead provides a more simplified interface.
+
+Beyond simplicity, a major benefit to using the Active Record features
+is that it allows you to create database independent applications, since
+the query syntax is generated by each database adapter. It also allows
+for safer queries, since the values are escaped automatically by the
+system.
+
+.. note:: If you intend to write your own queries you can disable this
+	class in your database config file, allowing the core database library
+	and adapter to utilize fewer resources.
+
+.. contents:: Page Contents
+
+**************
+Selecting Data
+**************
+
+The following functions allow you to build SQL **SELECT** statements.
+
+$this->db->get()
+================
+
+Runs the selection query and returns the result. Can be used by itself
+to retrieve all records from a table::
+
+	$query = $this->db->get('mytable');  // Produces: SELECT * FROM mytable
+
+The second and third parameters enable you to set a limit and offset
+clause::
+
+	$query = $this->db->get('mytable', 10, 20);
+	// Produces: SELECT * FROM mytable LIMIT 20, 10 (in MySQL. Other databases have slightly different syntax)
+
+You'll notice that the above function is assigned to a variable named
+$query, which can be used to show the results::
+
+	$query = $this->db->get('mytable');
+	
+	foreach ($query->result() as $row)
+	{
+		echo $row->title;
+	}
+
+Please visit the :doc:`result functions <results>` page for a full
+discussion regarding result generation.
+
+$this->db->get_where()
+======================
+
+Identical to the above function except that it permits you to add a
+"where" clause in the second parameter, instead of using the db->where()
+function::
+
+	$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);
+
+Please read the about the where function below for more information.
+
+Note: get_where() was formerly known as getwhere(), which has been
+removed
+
+$this->db->select()
+===================
+
+Permits you to write the SELECT portion of your query::
+
+	$this->db->select('title, content, date');
+	$query = $this->db->get('mytable');  // Produces: SELECT title, content, date FROM mytable
+
+
+.. note:: If you are selecting all (\*) from a table you do not need to
+	use this function. When omitted, CodeIgniter assumes you wish to SELECT *
+
+$this->db->select() accepts an optional second parameter. If you set it
+to FALSE, CodeIgniter will not try to protect your field or table names
+with backticks. This is useful if you need a compound select statement.
+
+::
+
+	$this->db->select('(SELECT SUM(payments.amount) FROM payments WHERE payments.invoice_id=4') AS amount_paid', FALSE); 
+	$query = $this->db->get('mytable');
+
+
+$this->db->select_max()
+=======================
+
+Writes a "SELECT MAX(field)" portion for your query. You can optionally
+include a second parameter to rename the resulting field.
+
+::
+
+	$this->db->select_max('age');
+	$query = $this->db->get('members');  // Produces: SELECT MAX(age) as age FROM members
+	
+	$this->db->select_max('age', 'member_age');
+	$query = $this->db->get('members'); // Produces: SELECT MAX(age) as member_age FROM members
+
+
+$this->db->select_min()
+=======================
+
+Writes a "SELECT MIN(field)" portion for your query. As with
+select_max(), You can optionally include a second parameter to rename
+the resulting field.
+
+::
+
+	$this->db->select_min('age');
+	$query = $this->db->get('members'); // Produces: SELECT MIN(age) as age FROM members
+
+
+$this->db->select_avg()
+=======================
+
+Writes a "SELECT AVG(field)" portion for your query. As with
+select_max(), You can optionally include a second parameter to rename
+the resulting field.
+
+::
+
+	$this->db->select_avg('age');
+	$query = $this->db->get('members'); // Produces: SELECT AVG(age) as age FROM members
+
+
+$this->db->select_sum()
+=======================
+
+Writes a "SELECT SUM(field)" portion for your query. As with
+select_max(), You can optionally include a second parameter to rename
+the resulting field.
+
+::
+
+	$this->db->select_sum('age');
+	$query = $this->db->get('members'); // Produces: SELECT SUM(age) as age FROM members
+
+
+$this->db->from()
+=================
+
+Permits you to write the FROM portion of your query::
+
+	$this->db->select('title, content, date');
+	$this->db->from('mytable');
+	$query = $this->db->get();  // Produces: SELECT title, content, date FROM mytable
+
+.. note:: As shown earlier, the FROM portion of your query can be specified
+	in the $this->db->get() function, so use whichever method you prefer.
+
+$this->db->join()
+=================
+
+Permits you to write the JOIN portion of your query::
+
+	$this->db->select('*');
+	$this->db->from('blogs');
+	$this->db->join('comments', 'comments.id = blogs.id');
+	$query = $this->db->get();
+	
+	// Produces:
+	// SELECT * FROM blogs // JOIN comments ON comments.id = blogs.id
+
+Multiple function calls can be made if you need several joins in one
+query.
+
+If you need a specific type of JOIN you can specify it via the third
+parameter of the function. Options are: left, right, outer, inner, left
+outer, and right outer.
+
+::
+
+	$this->db->join('comments', 'comments.id = blogs.id', 'left');
+	// Produces: LEFT JOIN comments ON comments.id = blogs.id
+
+$this->db->where()
+==================
+
+This function enables you to set **WHERE** clauses using one of four
+methods:
+
+.. note:: All values passed to this function are escaped automatically,
+	producing safer queries.
+
+#. **Simple key/value method:**
+
+	::
+
+		$this->db->where('name', $name); // Produces: WHERE name = 'Joe' 
+
+	Notice that the equal sign is added for you.
+
+	If you use multiple function calls they will be chained together with
+	AND between them:
+
+	::
+
+		$this->db->where('name', $name);
+		$this->db->where('title', $title);
+		$this->db->where('status', $status);
+		// WHERE name = 'Joe' AND title = 'boss' AND status = 'active'  
+
+#. **Custom key/value method:**
+	You can include an operator in the first parameter in order to
+	control the comparison:
+
+	::
+
+		$this->db->where('name !=', $name);
+		$this->db->where('id <', $id); // Produces: WHERE name != 'Joe' AND id < 45    
+
+#. **Associative array method:**
+
+	::
+
+		$array = array('name' => $name, 'title' => $title, 'status' => $status);
+		$this->db->where($array);
+		// Produces: WHERE name = 'Joe' AND title = 'boss' AND status = 'active'    
+
+	You can include your own operators using this method as well:
+
+	::
+
+		$array = array('name !=' => $name, 'id <' => $id, 'date >' => $date);
+		$this->db->where($array);
+
+#. **Custom string:**
+	You can write your own clauses manually::
+
+		$where = "name='Joe' AND status='boss' OR status='active'";
+		$this->db->where($where);
+
+
+$this->db->where() accepts an optional third parameter. If you set it to
+FALSE, CodeIgniter will not try to protect your field or table names
+with backticks.
+
+::
+
+	$this->db->where('MATCH (field) AGAINST ("value")', NULL, FALSE);
+
+
+$this->db->or_where()
+=====================
+
+This function is identical to the one above, except that multiple
+instances are joined by OR::
+
+	$this->db->where('name !=', $name);
+	$this->db->or_where('id >', $id);  // Produces: WHERE name != 'Joe' OR id > 50
+
+.. note:: or_where() was formerly known as orwhere(), which has been
+	removed.
+
+$this->db->where_in()
+=====================
+
+Generates a WHERE field IN ('item', 'item') SQL query joined with AND if
+appropriate
+
+::
+
+	$names = array('Frank', 'Todd', 'James');
+	$this->db->where_in('username', $names);
+	// Produces: WHERE username IN ('Frank', 'Todd', 'James')
+
+
+$this->db->or_where_in()
+========================
+
+Generates a WHERE field IN ('item', 'item') SQL query joined with OR if
+appropriate
+
+::
+
+	$names = array('Frank', 'Todd', 'James');
+	$this->db->or_where_in('username', $names);
+	// Produces: OR username IN ('Frank', 'Todd', 'James')
+
+
+$this->db->where_not_in()
+=========================
+
+Generates a WHERE field NOT IN ('item', 'item') SQL query joined with
+AND if appropriate
+
+::
+
+	$names = array('Frank', 'Todd', 'James');
+	$this->db->where_not_in('username', $names);
+	// Produces: WHERE username NOT IN ('Frank', 'Todd', 'James')
+
+
+$this->db->or_where_not_in()
+============================
+
+Generates a WHERE field NOT IN ('item', 'item') SQL query joined with OR
+if appropriate
+
+::
+
+	$names = array('Frank', 'Todd', 'James');
+	$this->db->or_where_not_in('username', $names);
+	// Produces: OR username NOT IN ('Frank', 'Todd', 'James')
+
+
+$this->db->like()
+=================
+
+This function enables you to generate **LIKE** clauses, useful for doing
+searches.
+
+.. note:: All values passed to this function are escaped automatically.
+
+#. **Simple key/value method:**
+
+	::
+
+		$this->db->like('title', 'match');     // Produces: WHERE title LIKE '%match%' 
+
+	If you use multiple function calls they will be chained together with
+	AND between them::
+
+		$this->db->like('title', 'match');
+		$this->db->like('body', 'match');
+		// WHERE title LIKE '%match%' AND  body LIKE '%match%
+
+	If you want to control where the wildcard (%) is placed, you can use
+	an optional third argument. Your options are 'before', 'after' and
+	'both' (which is the default).
+
+	::
+
+		$this->db->like('title', 'match', 'before');	// Produces: WHERE title LIKE '%match'
+		$this->db->like('title', 'match', 'after');		// Produces: WHERE title LIKE 'match%'
+		$this->db->like('title', 'match', 'both');		// Produces: WHERE title LIKE '%match%' 
+
+#. **Associative array method:**
+
+	::
+
+		$array = array('title' => $match, 'page1' => $match, 'page2' => $match);
+		$this->db->like($array);
+		// WHERE title LIKE '%match%' AND  page1 LIKE '%match%' AND  page2 LIKE '%match%'
+
+
+$this->db->or_like()
+====================
+
+This function is identical to the one above, except that multiple
+instances are joined by OR::
+
+	$this->db->like('title', 'match'); $this->db->or_like('body', $match);
+	// WHERE title LIKE '%match%' OR  body LIKE '%match%'
+
+.. note:: or_like() was formerly known as orlike(), which has been removed.
+
+$this->db->not_like()
+=====================
+
+This function is identical to **like()**, except that it generates NOT
+LIKE statements::
+
+	$this->db->not_like('title', 'match');  // WHERE title NOT LIKE '%match%
+
+$this->db->or_not_like()
+========================
+
+This function is identical to **not_like()**, except that multiple
+instances are joined by OR::
+
+	$this->db->like('title', 'match');
+	$this->db->or_not_like('body', 'match');
+	// WHERE title  LIKE '%match% OR body NOT LIKE '%match%'
+
+$this->db->group_by()
+=====================
+
+Permits you to write the GROUP BY portion of your query::
+
+	$this->db->group_by("title"); // Produces: GROUP BY title
+
+You can also pass an array of multiple values as well::
+
+	$this->db->group_by(array("title", "date"));  // Produces: GROUP BY title, date
+
+.. note:: group_by() was formerly known as groupby(), which has been
+	removed.
+
+$this->db->distinct()
+=====================
+
+Adds the "DISTINCT" keyword to a query
+
+::
+
+	$this->db->distinct();
+	$this->db->get('table'); // Produces: SELECT DISTINCT * FROM table
+
+
+$this->db->having()
+===================
+
+Permits you to write the HAVING portion of your query. There are 2
+possible syntaxes, 1 argument or 2::
+
+	$this->db->having('user_id = 45');  // Produces: HAVING user_id = 45
+	$this->db->having('user_id',  45);  // Produces: HAVING user_id = 45 
+
+You can also pass an array of multiple values as well::
+
+	$this->db->having(array('title =' => 'My Title', 'id <' => $id));
+	// Produces: HAVING title = 'My Title', id < 45
+
+
+If you are using a database that CodeIgniter escapes queries for, you
+can prevent escaping content by passing an optional third argument, and
+setting it to FALSE.
+
+::
+
+	$this->db->having('user_id',  45);  // Produces: HAVING `user_id` = 45 in some databases such as MySQL
+	$this->db->having('user_id',  45, FALSE);  // Produces: HAVING user_id = 45
+
+
+$this->db->or_having()
+======================
+
+Identical to having(), only separates multiple clauses with "OR".
+
+$this->db->order_by()
+=====================
+
+Lets you set an ORDER BY clause. The first parameter contains the name
+of the column you would like to order by. The second parameter lets you
+set the direction of the result. Options are asc or desc, or random.
+
+::
+
+	$this->db->order_by("title", "desc");  // Produces: ORDER BY title DESC
+
+You can also pass your own string in the first parameter::
+
+	$this->db->order_by('title desc, name asc');  // Produces: ORDER BY title DESC, name ASC
+
+Or multiple function calls can be made if you need multiple fields.
+
+::
+
+	$this->db->order_by("title", "desc");
+	$this->db->order_by("name", "asc"); // Produces: ORDER BY title DESC, name ASC     
+
+
+.. note:: order_by() was formerly known as orderby(), which has been
+	removed.
+
+.. note:: random ordering is not currently supported in Oracle or MSSQL
+	drivers. These will default to 'ASC'.
+
+$this->db->limit()
+==================
+
+Lets you limit the number of rows you would like returned by the query::
+
+	$this->db->limit(10);  // Produces: LIMIT 10
+
+The second parameter lets you set a result offset.
+
+::
+
+	$this->db->limit(10, 20);  // Produces: LIMIT 20, 10 (in MySQL.  Other databases have slightly different syntax)
+
+$this->db->count_all_results()
+==============================
+
+Permits you to determine the number of rows in a particular Active
+Record query. Queries will accept Active Record restrictors such as
+where(), or_where(), like(), or_like(), etc. Example::
+
+	echo $this->db->count_all_results('my_table');  // Produces an integer, like 25
+	$this->db->like('title', 'match');
+	$this->db->from('my_table');
+	echo $this->db->count_all_results(); // Produces an integer, like 17 
+
+$this->db->count_all()
+======================
+
+Permits you to determine the number of rows in a particular table.
+Submit the table name in the first parameter. Example::
+
+	echo $this->db->count_all('my_table');  // Produces an integer, like 25
+
+**************
+Inserting Data
+**************
+
+$this->db->insert()
+===================
+
+Generates an insert string based on the data you supply, and runs the
+query. You can either pass an **array** or an **object** to the
+function. Here is an example using an array::
+
+	$data = array(
+		'title' => 'My title',
+		'name' => 'My Name',
+		'date' => 'My date'
+	);
+	
+	$this->db->insert('mytable', $data);
+	// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
+
+The first parameter will contain the table name, the second is an
+associative array of values.
+
+Here is an example using an object::
+
+	/*
+	class Myclass {
+		var  $title = 'My Title';
+		var  $content = 'My Content';
+		var  $date = 'My Date';
+	}
+	*/
+	
+	$object = new Myclass;
+	$this->db->insert('mytable', $object);
+	// Produces: INSERT INTO mytable (title, content, date) VALUES ('My Title', 'My Content', 'My Date')
+
+The first parameter will contain the table name, the second is an
+object.
+
+.. note:: All values are escaped automatically producing safer queries.
+
+$this->db->insert_batch()
+=========================
+
+Generates an insert string based on the data you supply, and runs the
+query. You can either pass an **array** or an **object** to the
+function. Here is an example using an array::
+
+	$data = array(
+		array(
+			'title' => 'My title',
+			'name' => 'My Name',
+			'date' => 'My date'
+		),
+		array(
+			'title' => 'Another title',
+			'name' => 'Another Name',
+			'date' => 'Another date'
+		)
+	);
+	
+	$this->db->insert_batch('mytable', $data);
+	// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'),  ('Another title', 'Another name', 'Another date')
+
+The first parameter will contain the table name, the second is an
+associative array of values.
+
+.. note:: All values are escaped automatically producing safer queries.
+
+$this->db->set()
+================
+
+This function enables you to set values for inserts or updates.
+
+**It can be used instead of passing a data array directly to the insert
+or update functions:**
+
+::
+
+	$this->db->set('name', $name);
+	$this->db->insert('mytable');  // Produces: INSERT INTO mytable (name) VALUES ('{$name}')
+
+If you use multiple function called they will be assembled properly
+based on whether you are doing an insert or an update::
+
+	$this->db->set('name', $name);
+	$this->db->set('title', $title);
+	$this->db->set('status', $status);
+	$this->db->insert('mytable'); 
+
+**set()** will also accept an optional third parameter ($escape), that
+will prevent data from being escaped if set to FALSE. To illustrate the
+difference, here is set() used both with and without the escape
+parameter.
+
+::
+
+	$this->db->set('field', 'field+1', FALSE);
+	$this->db->insert('mytable'); // gives INSERT INTO mytable (field) VALUES (field+1)
+	$this->db->set('field', 'field+1');
+	$this->db->insert('mytable'); // gives INSERT INTO mytable (field) VALUES ('field+1')
+
+
+You can also pass an associative array to this function::
+
+	$array = array(
+		'name' => $name,
+		'title' => $title,
+		'status' => $status
+	);
+	
+	$this->db->set($array);
+	$this->db->insert('mytable');
+
+Or an object::
+
+	/*
+	class Myclass {
+		var  $title = 'My Title';
+		var  $content = 'My Content';
+		var  $date = 'My Date';
+	}
+	*/
+	
+	$object = new Myclass;
+	$this->db->set($object);
+	$this->db->insert('mytable');
+
+
+*************
+Updating Data
+*************
+
+$this->db->update()
+===================
+
+Generates an update string and runs the query based on the data you
+supply. You can pass an **array** or an **object** to the function. Here
+is an example using an array::
+
+	$data = array(
+		'title' => $title,
+		'name' => $name,
+		'date' => $date
+	);
+	
+	$this->db->where('id', $id);
+	$this->db->update('mytable', $data);
+	// Produces: // UPDATE mytable  // SET title = '{$title}', name = '{$name}', date = '{$date}' // WHERE id = $id
+
+Or you can supply an object::
+
+	/*
+	class Myclass {
+		var  $title = 'My Title';
+		var  $content = 'My Content';
+		var  $date = 'My Date';
+	}
+	*/
+	
+	$object = new Myclass;
+	$this->db->where('id', $id);
+	$this->db->update('mytable', $object);
+	// Produces: // UPDATE mytable  // SET title = '{$title}', name = '{$name}', date = '{$date}' // WHERE id = $id
+
+.. note:: All values are escaped automatically producing safer queries.
+
+You'll notice the use of the $this->db->where() function, enabling you
+to set the WHERE clause. You can optionally pass this information
+directly into the update function as a string::
+
+	$this->db->update('mytable', $data, "id = 4");
+
+Or as an array::
+
+	$this->db->update('mytable', $data, array('id' => $id));
+
+You may also use the $this->db->set() function described above when
+performing updates.
+
+$this->db->update_batch()
+=========================
+
+Generates an update string based on the data you supply, and runs the query.
+You can either pass an **array** or an **object** to the function.
+Here is an example using an array::
+
+	$data = array(
+	   array(
+	      'title' => 'My title' ,
+	      'name' => 'My Name 2' ,
+	      'date' => 'My date 2'
+	   ),
+	   array(
+	      'title' => 'Another title' ,
+	      'name' => 'Another Name 2' ,
+	      'date' => 'Another date 2'
+	   )
+	);
+
+	$this->db->update_batch('mytable', $data, 'title'); 
+
+	// Produces: 
+	// UPDATE `mytable` SET `name` = CASE
+	// WHEN `title` = 'My title' THEN 'My Name 2'
+	// WHEN `title` = 'Another title' THEN 'Another Name 2'
+	// ELSE `name` END,
+	// `date` = CASE 
+	// WHEN `title` = 'My title' THEN 'My date 2'
+	// WHEN `title` = 'Another title' THEN 'Another date 2'
+	// ELSE `date` END
+	// WHERE `title` IN ('My title','Another title')
+
+The first parameter will contain the table name, the second is an associative
+array of values, the third parameter is the where key.
+
+.. note:: All values are escaped automatically producing safer queries.
+
+
+*************
+Deleting Data
+*************
+
+$this->db->delete()
+===================
+
+Generates a delete SQL string and runs the query.
+
+::
+
+	$this->db->delete('mytable', array('id' => $id));  // Produces: // DELETE FROM mytable  // WHERE id = $id
+
+The first parameter is the table name, the second is the where clause.
+You can also use the where() or or_where() functions instead of passing
+the data to the second parameter of the function::
+
+	$this->db->where('id', $id);
+	$this->db->delete('mytable');
+	
+	// Produces:
+	// DELETE FROM mytable
+	// WHERE id = $id
+
+
+An array of table names can be passed into delete() if you would like to
+delete data from more than 1 table.
+
+::
+
+	$tables = array('table1', 'table2', 'table3');
+	$this->db->where('id', '5');
+	$this->db->delete($tables);
+
+
+If you want to delete all data from a table, you can use the truncate()
+function, or empty_table().
+
+$this->db->empty_table()
+========================
+
+Generates a delete SQL string and runs the
+query.::
+
+	  $this->db->empty_table('mytable'); // Produces // DELETE FROM mytable
+
+
+$this->db->truncate()
+=====================
+
+Generates a truncate SQL string and runs the query.
+
+::
+
+	$this->db->from('mytable');
+	$this->db->truncate();  
+	
+	// or  
+	
+	$this->db->truncate('mytable');
+	
+	// Produce:
+	// TRUNCATE mytable 
+
+.. note:: If the TRUNCATE command isn't available, truncate() will
+	execute as "DELETE FROM table".
+
+***************
+Method Chaining
+***************
+
+Method chaining allows you to simplify your syntax by connecting
+multiple functions. Consider this example::
+
+	$query = $this->db->select('title')
+				->where('id', $id)
+				->limit(10, 20)
+				->get('mytable');
+
+.. note:: Method chaining only works with PHP 5.
+
+.. _ar-caching:
+
+*********************
+Active Record Caching
+*********************
+
+While not "true" caching, Active Record enables you to save (or "cache")
+certain parts of your queries for reuse at a later point in your
+script's execution. Normally, when an Active Record call is completed,
+all stored information is reset for the next call. With caching, you can
+prevent this reset, and reuse information easily.
+
+Cached calls are cumulative. If you make 2 cached select() calls, and
+then 2 uncached select() calls, this will result in 4 select() calls.
+There are three Caching functions available:
+
+$this->db->start_cache()
+========================
+
+This function must be called to begin caching. All Active Record queries
+of the correct type (see below for supported queries) are stored for
+later use.
+
+$this->db->stop_cache()
+=======================
+
+This function can be called to stop caching.
+
+$this->db->flush_cache()
+========================
+
+This function deletes all items from the Active Record cache.
+
+Here's a usage example::
+
+	$this->db->start_cache();
+	$this->db->select('field1');
+	$this->db->stop_cache();
+	$this->db->get('tablename');
+	//Generates: SELECT `field1` FROM (`tablename`)
+	
+	$this->db->select('field2');
+	$this->db->get('tablename');
+	//Generates:  SELECT `field1`, `field2` FROM (`tablename`)
+	
+	$this->db->flush_cache();
+	$this->db->select('field2');
+	$this->db->get('tablename');
+	//Generates:  SELECT `field2` FROM (`tablename`)
+
+
+.. note:: The following statements can be cached: select, from, join,
+	where, like, group_by, having, order_by, set

+######################
+Database Caching Class
+######################
+
+The Database Caching Class permits you to cache your queries as text
+files for reduced database load.
+
+.. important:: This class is initialized automatically by the database
+	driver when caching is enabled. Do NOT load this class manually.
+
+.. important:: Not all query result functions are available when you
+	use caching. Please read this page carefully.
+
+Enabling Caching
+================
+
+Caching is enabled in three steps:
+
+-  Create a writable directory on your server where the cache files can
+   be stored.
+-  Set the path to your cache folder in your
+   application/config/database.php file.
+-  Enable the caching feature, either globally by setting the preference
+   in your application/config/database.php file, or manually as
+   described below.
+
+Once enabled, caching will happen automatically whenever a page is
+loaded that contains database queries.
+
+How Does Caching Work?
+======================
+
+CodeIgniter's query caching system happens dynamically when your pages
+are viewed. When caching is enabled, the first time a web page is
+loaded, the query result object will be serialized and stored in a text
+file on your server. The next time the page is loaded the cache file
+will be used instead of accessing your database. Your database usage can
+effectively be reduced to zero for any pages that have been cached.
+
+Only read-type (SELECT) queries can be cached, since these are the only
+type of queries that produce a result. Write-type (INSERT, UPDATE, etc.)
+queries, since they don't generate a result, will not be cached by the
+system.
+
+Cache files DO NOT expire. Any queries that have been cached will remain
+cached until you delete them. The caching system permits you clear
+caches associated with individual pages, or you can delete the entire
+collection of cache files. Typically you'll want to use the housekeeping
+functions described below to delete cache files after certain events
+take place, like when you've added new information to your database.
+
+Will Caching Improve Your Site's Performance?
+=============================================
+
+Getting a performance gain as a result of caching depends on many
+factors. If you have a highly optimized database under very little load,
+you probably won't see a performance boost. If your database is under
+heavy use you probably will see an improved response, assuming your
+file-system is not overly taxed. Remember that caching simply changes
+how your information is retrieved, shifting it from being a database
+operation to a file-system one.
+
+In some clustered server environments, for example, caching may be
+detrimental since file-system operations are so intense. On single
+servers in shared environments, caching will probably be beneficial.
+Unfortunately there is no single answer to the question of whether you
+should cache your database. It really depends on your situation.
+
+How are Cache Files Stored?
+===========================
+
+CodeIgniter places the result of EACH query into its own cache file.
+Sets of cache files are further organized into sub-folders corresponding
+to your controller functions. To be precise, the sub-folders are named
+identically to the first two segments of your URI (the controller class
+name and function name).
+
+For example, let's say you have a controller called blog with a function
+called comments that contains three queries. The caching system will
+create a cache folder called blog+comments, into which it will write
+three cache files.
+
+If you use dynamic queries that change based on information in your URI
+(when using pagination, for example), each instance of the query will
+produce its own cache file. It's possible, therefore, to end up with
+many times more cache files than you have queries.
+
+Managing your Cache Files
+=========================
+
+Since cache files do not expire, you'll need to build deletion routines
+into your application. For example, let's say you have a blog that
+allows user commenting. Whenever a new comment is submitted you'll want
+to delete the cache files associated with the controller function that
+serves up your comments. You'll find two delete functions described
+below that help you clear data.
+
+Not All Database Functions Work with Caching
+============================================
+
+Lastly, we need to point out that the result object that is cached is a
+simplified version of the full result object. For that reason, some of
+the query result functions are not available for use.
+
+The following functions ARE NOT available when using a cached result
+object:
+
+-  num_fields()
+-  field_names()
+-  field_data()
+-  free_result()
+
+Also, the two database resources (result_id and conn_id) are not
+available when caching, since result resources only pertain to run-time
+operations.
+
+******************
+Function Reference
+******************
+
+$this->db->cache_on() / $this->db->cache_off()
+================================================
+
+Manually enables/disables caching. This can be useful if you want to
+keep certain queries from being cached. Example::
+
+	 // Turn caching on $this->db->cache_on(); $query = $this->db->query("SELECT * FROM mytable");  // Turn caching off for this one query $this->db->cache_off(); $query = $this->db->query("SELECT * FROM members WHERE member_id = '$current_user'");  // Turn caching back on $this->db->cache_on(); $query = $this->db->query("SELECT * FROM another_table");
+
+$this->db->cache_delete()
+==========================
+
+Deletes the cache files associated with a particular page. This is
+useful if you need to clear caching after you update your database.
+
+The caching system saves your cache files to folders that correspond to
+the URI of the page you are viewing. For example, if you are viewing a
+page at example.com/index.php/blog/comments, the caching system will put
+all cache files associated with it in a folder called blog+comments. To
+delete those particular cache files you will use::
+
+	$this->db->cache_delete('blog', 'comments');
+
+If you do not use any parameters the current URI will be used when
+determining what should be cleared.
+
+$this->db->cache_delete_all()
+===============================
+
+Clears all existing cache files. Example::
+
+	$this->db->cache_delete_all();

+#####################
+Custom Function Calls
+#####################
+
+$this->db->call_function();
+============================
+
+This function enables you to call PHP database functions that are not
+natively included in CodeIgniter, in a platform independent manner. For
+example, lets say you want to call the mysql_get_client_info()
+function, which is **not** natively supported by CodeIgniter. You could
+do so like this::
+
+	$this->db->call_function('get_client_info');
+
+You must supply the name of the function, **without** the mysql\_
+prefix, in the first parameter. The prefix is added automatically based
+on which database driver is currently being used. This permits you to
+run the same function on different database platforms. Obviously not all
+function calls are identical between platforms, so there are limits to
+how useful this function can be in terms of portability.
+
+Any parameters needed by the function you are calling will be added to
+the second parameter.
+
+::
+
+	$this->db->call_function('some_function', $param1, $param2, etc..);
+
+Often, you will either need to supply a database connection ID or a
+database result ID. The connection ID can be accessed using::
+
+	$this->db->conn_id;
+
+The result ID can be accessed from within your result object, like this::
+
+	$query = $this->db->query("SOME QUERY");  $query->result_id;

+######################
+Database Configuration
+######################
+
+CodeIgniter has a config file that lets you store your database
+connection values (username, password, database name, etc.). The config
+file is located at application/config/database.php. You can also set
+database connection values for specific
+:doc:`environments <../libraries/config>` by placing **database.php**
+it the respective environment config folder.
+
+The config settings are stored in a multi-dimensional array with this
+prototype::
+
+	$db['default']['hostname'] = "localhost"; $db['default']['username'] = "root"; $db['default']['password'] = ""; $db['default']['database'] = "database_name"; $db['default']['dbdriver'] = "mysql"; $db['default']['dbprefix'] = ""; $db['default']['pconnect'] = TRUE; $db['default']['db_debug'] = FALSE; $db['default']['cache_on'] = FALSE; $db['default']['cachedir'] =  ""; $db['default']['char_set'] = "utf8"; $db['default']['dbcollat'] = "utf8_general_ci"; $db['default']['swap_pre'] = ""; $db['default']['autoinit'] = TRUE; $db['default']['stricton'] = FALSE;
+
+The reason we use a multi-dimensional array rather than a more simple
+one is to permit you to optionally store multiple sets of connection
+values. If, for example, you run multiple environments (development,
+production, test, etc.) under a single installation, you can set up a
+connection group for each, then switch between groups as needed. For
+example, to set up a "test" environment you would do this::
+
+	$db['test']['hostname'] = "localhost"; $db['test']['username'] = "root"; $db['test']['password'] = ""; $db['test']['database'] = "database_name"; $db['test']['dbdriver'] = "mysql"; $db['test']['dbprefix'] = ""; $db['test']['pconnect'] = TRUE; $db['test']['db_debug'] = FALSE; $db['test']['cache_on'] = FALSE; $db['test']['cachedir'] =  ""; $db['test']['char_set'] = "utf8"; $db['test']['dbcollat'] = "utf8_general_ci"; $db['test']['swap_pre'] = ""; $db['test']['autoinit'] = TRUE; $db['test']['stricton'] = FALSE;
+
+Then, to globally tell the system to use that group you would set this
+variable located in the config file::
+
+	$active_group = "test";
+
+Note: The name "test" is arbitrary. It can be anything you want. By
+default we've used the word "default" for the primary connection, but it
+too can be renamed to something more relevant to your project.
+
+Active Record
+-------------
+
+The :doc:`Active Record Class <active_record>` is globally enabled or
+disabled by setting the $active_record variable in the database
+configuration file to TRUE/FALSE (boolean). If you are not using the
+active record class, setting it to FALSE will utilize fewer resources
+when the database classes are initialized.
+
+::
+
+	$active_record = TRUE;
+
+.. note:: that some CodeIgniter classes such as Sessions require Active
+	Records be enabled to access certain functionality.
+
+Explanation of Values:
+----------------------
+
+-  **hostname** - The hostname of your database server. Often this is
+	"localhost".
+-  **username** - The username used to connect to the database.
+-  **password** - The password used to connect to the database.
+-  **database** - The name of the database you want to connect to.
+-  **dbdriver** - The database type. ie: mysql, postgres, odbc, etc.
+	Must be specified in lower case.
+-  **dbprefix** - An optional table prefix which will added to the table
+	name when running :doc:`Active Record <active_record>` queries. This
+	permits multiple CodeIgniter installations to share one database.
+-  **pconnect** - TRUE/FALSE (boolean) - Whether to use a persistent
+	connection.
+-  **db_debug** - TRUE/FALSE (boolean) - Whether database errors should
+	be displayed.
+-  **cache_on** - TRUE/FALSE (boolean) - Whether database query caching
+	is enabled, see also :doc:`Database Caching Class <caching>`.
+-  **cachedir** - The absolute server path to your database query cache
+	directory.
+-  **char_set** - The character set used in communicating with the
+	database.
+-  **dbcollat** - The character collation used in communicating with the
+	database.
+
+.. note:: For MySQL and MySQLi databases, this setting is only used
+	as a backup if your server is running PHP < 5.2.3 or MySQL < 5.0.7
+	(and in table creation queries made with DB Forge). There is an
+	incompatibility in PHP with mysql_real_escape_string() which can
+	make your site vulnerable to SQL injection if you are using a
+	multi-byte character set and are running versions lower than these.
+	Sites using Latin-1 or UTF-8 database character set and collation are
+	unaffected.
+
+-  **swap_pre** - A default table prefix that should be swapped with
+	dbprefix. This is useful for distributed applications where you might
+	run manually written queries, and need the prefix to still be
+	customizable by the end user.
+-  **autoinit** - Whether or not to automatically connect to the
+	database when the library loads. If set to false, the connection will
+	take place prior to executing the first query.
+-  **stricton** - TRUE/FALSE (boolean) - Whether to force "Strict Mode"
+	connections, good for ensuring strict SQL while developing an
+	application.
+-  **port** - The database port number. To use this value you have to
+	add a line to the database config
+	array.::
+
+	$db['default']['port'] =  5432;
+
+
+.. note:: Depending on what database platform you are using (MySQL,
+	Postgres, etc.) not all values will be needed. For example, when using
+	SQLite you will not need to supply a username or password, and the
+	database name will be the path to your database file. The information
+	above assumes you are using MySQL.

+###########################
+Connecting to your Database
+###########################
+
+There are two ways to connect to a database:
+
+Automatically Connecting
+========================
+
+The "auto connect" feature will load and instantiate the database class
+with every page load. To enable "auto connecting", add the word database
+to the library array, as indicated in the following file:
+
+application/config/autoload.php
+
+Manually Connecting
+===================
+
+If only some of your pages require database connectivity you can
+manually connect to your database by adding this line of code in any
+function where it is needed, or in your class constructor to make the
+database available globally in that class.
+
+::
+
+	$this->load->database();
+
+If the above function does **not** contain any information in the first
+parameter it will connect to the group specified in your database config
+file. For most people, this is the preferred method of use.
+
+Available Parameters
+--------------------
+
+#. The database connection values, passed either as an array or a DSN
+   string.
+#. TRUE/FALSE (boolean). Whether to return the connection ID (see
+   Connecting to Multiple Databases below).
+#. TRUE/FALSE (boolean). Whether to enable the Active Record class. Set
+   to TRUE by default.
+
+Manually Connecting to a Database
+---------------------------------
+
+The first parameter of this function can **optionally** be used to
+specify a particular database group from your config file, or you can
+even submit connection values for a database that is not specified in
+your config file. Examples:
+
+To choose a specific group from your config file you can do this::
+
+	$this->load->database('group_name');
+
+Where group_name is the name of the connection group from your config
+file.
+
+To connect manually to a desired database you can pass an array of
+values::
+
+	$config['hostname'] = "localhost"; $config['username'] = "myusername"; $config['password'] = "mypassword"; $config['database'] = "mydatabase"; $config['dbdriver'] = "mysql"; $config['dbprefix'] = ""; $config['pconnect'] = FALSE; $config['db_debug'] = TRUE; $config['cache_on'] = FALSE; $config['cachedir'] = ""; $config['char_set'] = "utf8"; $config['dbcollat'] = "utf8_general_ci";  $this->load->database($config);
+
+For information on each of these values please see the :doc:`configuration
+page <configuration>`.
+
+.. note:: For the PDO driver, $config['hostname'] should look like
+	this: 'mysql:host=localhost'
+
+Or you can submit your database values as a Data Source Name. DSNs must
+have this prototype::
+
+	$dsn = 'dbdriver://username:password@hostname/database';  $this->load->database($dsn);
+
+To override default config values when connecting with a DSN string, add
+the config variables as a query string.
+
+::
+
+	$dsn = 'dbdriver://username:password@hostname/database?char_set=utf8&dbcollat=utf8_general_ci&cache_on=true&cachedir=/path/to/cache';  $this->load->database($dsn);
+
+Connecting to Multiple Databases
+================================
+
+If you need to connect to more than one database simultaneously you can
+do so as follows::
+
+	$DB1 = $this->load->database('group_one', TRUE); $DB2 = $this->load->database('group_two', TRUE);
+
+Note: Change the words "group_one" and "group_two" to the specific
+group names you are connecting to (or you can pass the connection values
+as indicated above).
+
+By setting the second parameter to TRUE (boolean) the function will
+return the database object.
+
+When you connect this way, you will use your object name to issue
+commands rather than the syntax used throughout this guide. In other
+words, rather than issuing commands with:
+
+$this->db->query();
+$this->db->result();
+etc...
+
+You will instead use:
+
+$DB1->query();
+$DB1->result();
+etc...
+
+Reconnecting / Keeping the Connection Alive
+===========================================
+
+If the database server's idle timeout is exceeded while you're doing
+some heavy PHP lifting (processing an image, for instance), you should
+consider pinging the server by using the reconnect() method before
+sending further queries, which can gracefully keep the connection alive
+or re-establish it.
+
+::
+
+	$this->db->reconnect();
+
+Manually closing the Connection
+===============================
+
+While CodeIgniter intelligently takes care of closing your database
+connections, you can explicitly close the connection.
+
+::
+
+	$this->db->close();
+

+##################################
+Database Quick Start: Example Code
+##################################
+
+The following page contains example code showing how the database class
+is used. For complete details please read the individual pages
+describing each function.
+
+Initializing the Database Class
+===============================
+
+The following code loads and initializes the database class based on
+your :doc:`configuration <configuration>` settings::
+
+	$this->load->database();
+
+Once loaded the class is ready to be used as described below.
+
+Note: If all your pages require database access you can connect
+automatically. See the :doc:`connecting <connecting>` page for details.
+
+Standard Query With Multiple Results (Object Version)
+=====================================================
+
+::
+
+	$query = $this->db->query('SELECT name, title, email FROM my_table');  foreach ($query->result() as $row) {     echo $row->title;     echo $row->name;     echo $row->email; }  echo 'Total Results: ' . $query->num_rows();
+
+The above result() function returns an array of **objects**. Example:
+$row->title
+
+Standard Query With Multiple Results (Array Version)
+====================================================
+
+::
+
+	$query = $this->db->query('SELECT name, title, email FROM my_table');  foreach ($query->result_array() as $row) {     echo $row['title'];     echo $row['name'];     echo $row['email']; }
+
+The above result_array() function returns an array of standard array
+indexes. Example: $row['title']
+
+Testing for Results
+===================
+
+If you run queries that might **not** produce a result, you are
+encouraged to test for a result first using the num_rows() function::
+
+	 $query = $this->db->query("YOUR QUERY");  if ($query->num_rows() > 0) {    foreach ($query->result() as $row)    {       echo $row->title;       echo $row->name;       echo $row->body;    } }
+
+Standard Query With Single Result
+=================================
+
+::
+
+	$query = $this->db->query('SELECT name FROM my_table LIMIT 1');  $row = $query->row(); echo $row->name;
+
+The above row() function returns an **object**. Example: $row->name
+
+Standard Query With Single Result (Array version)
+=================================================
+
+::
+
+	$query = $this->db->query('SELECT name FROM my_table LIMIT 1');  $row = $query->row_array(); echo $row['name'];
+
+The above row_array() function returns an **array**. Example:
+$row['name']
+
+Standard Insert
+===============
+
+::
+
+	 $sql = "INSERT INTO mytable (title, name)          VALUES (".$this->db->escape($title).", ".$this->db->escape($name).")";  $this->db->query($sql);  echo $this->db->affected_rows();
+
+Active Record Query
+===================
+
+The :doc:`Active Record Pattern <active_record>` gives you a simplified
+means of retrieving data::
+
+	 $query = $this->db->get('table_name');  foreach ($query->result() as $row) {     echo $row->title; }
+
+The above get() function retrieves all the results from the supplied
+table. The :doc:`Active Record <active_record>` class contains a full
+compliment of functions for working with data.
+
+Active Record Insert
+====================
+
+::
+
+	 $data = array(                'title' => $title,                'name' => $name,                'date' => $date             );  $this->db->insert('mytable', $data);  // Produces: INSERT INTO mytable (title, name, date) VALUES ('{$title}', '{$name}', '{$date}')

+##########
+Field Data
+##########
+
+$this->db->list_fields()
+=========================
+
+Returns an array containing the field names. This query can be called
+two ways:
+
+1. You can supply the table name and call it from the $this->db->
+object::
+
+	 $fields = $this->db->list_fields('table_name');  foreach ($fields as $field) {    echo $field; }
+
+2. You can gather the field names associated with any query you run by
+calling the function from your query result object::
+
+	 $query = $this->db->query('SELECT * FROM some_table');   foreach ($query->list_fields() as $field) {    echo $field; }
+
+$this->db->field_exists()
+==========================
+
+Sometimes it's helpful to know whether a particular field exists before
+performing an action. Returns a boolean TRUE/FALSE. Usage example::
+
+	 if ($this->db->field_exists('field_name', 'table_name')) {    // some code... }
+
+Note: Replace *field_name* with the name of the column you are looking
+for, and replace *table_name* with the name of the table you are
+looking for.
+
+$this->db->field_data()
+========================
+
+Returns an array of objects containing field information.
+
+Sometimes it's helpful to gather the field names or other metadata, like
+the column type, max length, etc.
+
+Note: Not all databases provide meta-data.
+
+Usage example::
+
+	 $fields = $this->db->field_data('table_name');  foreach ($fields as $field) {    echo $field->name;    echo $field->type;    echo $field->max_length;    echo $field->primary_key; }
+
+If you have run a query already you can use the result object instead of
+supplying the table name::
+
+	 $query = $this->db->query("YOUR QUERY"); $fields = $query->field_data();
+
+The following data is available from this function if supported by your
+database:
+
+-  name - column name
+-  max_length - maximum length of the column
+-  primary_key - 1 if the column is a primary key
+-  type - the type of the column

+####################
+Database Forge Class
+####################
+
+The Database Forge Class contains functions that help you manage your
+database.
+
+.. contents:: Table of Contents
+
+****************************
+Initializing the Forge Class
+****************************
+
+.. important:: In order to initialize the Forge class, your database
+	driver must already be running, since the forge class relies on it.
+
+Load the Forge Class as follows::
+
+	$this->load->dbforge()
+
+Once initialized you will access the functions using the $this->dbforge
+object::
+
+	$this->dbforge->some_function()
+
+$this->dbforge->create_database('db_name')
+============================================
+
+Permits you to create the database specified in the first parameter.
+Returns TRUE/FALSE based on success or failure::
+
+	if ($this->dbforge->create_database('my_db')) {     echo 'Database created!'; }
+
+$this->dbforge->drop_database('db_name')
+==========================================
+
+Permits you to drop the database specified in the first parameter.
+Returns TRUE/FALSE based on success or failure::
+
+	if ($this->dbforge->drop_database('my_db')) {     echo 'Database deleted!'; }
+
+****************************
+Creating and Dropping Tables
+****************************
+
+There are several things you may wish to do when creating tables. Add
+fields, add keys to the table, alter columns. CodeIgniter provides a
+mechanism for this.
+
+Adding fields
+=============
+
+Fields are created via an associative array. Within the array you must
+include a 'type' key that relates to the datatype of the field. For
+example, INT, VARCHAR, TEXT, etc. Many datatypes (for example VARCHAR)
+also require a 'constraint' key.
+
+::
+
+	$fields = array(                         'users' => array(                                                      'type' => 'VARCHAR',                                                      'constraint' => '100',                                               ),                     );      // will translate to "users VARCHAR(100)" when the field is added.
+
+
+Additionally, the following key/values can be used:
+
+-  unsigned/true : to generate "UNSIGNED" in the field definition.
+-  default/value : to generate a default value in the field definition.
+-  null/true : to generate "NULL" in the field definition. Without this,
+   the field will default to "NOT NULL".
+-  auto_increment/true : generates an auto_increment flag on the
+   field. Note that the field type must be a type that supports this,
+   such as integer.
+
+::
+
+	$fields = array(                             'blog_id' => array(                                                      'type' => 'INT',                                                      'constraint' => 5,                                                       'unsigned' => TRUE,                                                      'auto_increment' => TRUE                                               ),                             'blog_title' => array(                                                  'type' => 'VARCHAR',                                                  'constraint' => '100',                                           ),                         'blog_author' => array(                                                  'type' =>'VARCHAR',                                                  'constraint' => '100',                                                  'default' => 'King of Town',                                           ),                         'blog_description' => array(                                                  'type' => 'TEXT',                                                  'null' => TRUE,                                           ),                 );
+
+
+After the fields have been defined, they can be added using
+$this->dbforge->add_field($fields); followed by a call to the
+create_table() function.
+
+$this->dbforge->add_field()
+----------------------------
+
+The add fields function will accept the above array.
+
+Passing strings as fields
+-------------------------
+
+If you know exactly how you want a field to be created, you can pass the
+string into the field definitions with add_field()
+
+::
+
+	$this->dbforge->add_field("label varchar(100) NOT NULL DEFAULT 'default label'");
+
+
+Note: Multiple calls to add_field() are cumulative.
+
+Creating an id field
+--------------------
+
+There is a special exception for creating id fields. A field with type
+id will automatically be assinged as an INT(9) auto_incrementing
+Primary Key.
+
+::
+
+	$this->dbforge->add_field('id');     // gives id INT(9) NOT NULL AUTO_INCREMENT
+
+
+Adding Keys
+===========
+
+Generally speaking, you'll want your table to have Keys. This is
+accomplished with $this->dbforge->add_key('field'). An optional second
+parameter set to TRUE will make it a primary key. Note that add_key()
+must be followed by a call to create_table().
+
+Multiple column non-primary keys must be sent as an array. Sample output
+below is for MySQL.
+
+::
+
+	$this->dbforge->add_key('blog_id', TRUE);     // gives PRIMARY KEY `blog_id` (`blog_id`)          $this->dbforge->add_key('blog_id', TRUE);     $this->dbforge->add_key('site_id', TRUE);     // gives PRIMARY KEY `blog_id_site_id` (`blog_id`, `site_id`)          $this->dbforge->add_key('blog_name');     // gives KEY `blog_name` (`blog_name`)          $this->dbforge->add_key(array('blog_name', 'blog_label'));     // gives KEY `blog_name_blog_label` (`blog_name`, `blog_label`)
+
+
+Creating a table
+================
+
+After fields and keys have been declared, you can create a new table
+with
+
+::
+
+	$this->dbforge->create_table('table_name'); // gives CREATE TABLE table_name
+
+
+An optional second parameter set to TRUE adds an "IF NOT EXISTS" clause
+into the definition
+
+::
+
+	$this->dbforge->create_table('table_name', TRUE); // gives CREATE TABLE IF NOT EXISTS table_name
+
+
+Dropping a table
+================
+
+Executes a DROP TABLE sql
+
+::
+
+	$this->dbforge->drop_table('table_name');     // gives DROP TABLE IF EXISTS  table_name
+
+
+Renaming a table
+================
+
+Executes a TABLE rename
+
+::
+
+	$this->dbforge->rename_table('old_table_name', 'new_table_name');     // gives ALTER TABLE old_table_name RENAME TO new_table_name
+
+
+****************
+Modifying Tables
+****************
+
+$this->dbforge->add_column()
+=============================
+
+The add_column() function is used to modify an existing table. It
+accepts the same field array as above, and can be used for an unlimited
+number of additional fields.
+
+::
+
+	$fields = array(                             'preferences' => array('type' => 'TEXT') ); $this->dbforge->add_column('table_name', $fields);  // gives ALTER TABLE table_name ADD     preferences TEXT
+
+An optional third parameter can be used to specify which existing column
+to add the new column after.
+
+::
+
+	$this->dbforge->add_column('table_name', $fields, 'after_field');
+
+
+$this->dbforge->drop_column()
+==============================
+
+Used to remove a column from a table.
+
+::
+
+	$this->dbforge->drop_column('table_name', 'column_to_drop');
+
+
+$this->dbforge->modify_column()
+================================
+
+The usage of this function is identical to add_column(), except it
+alters an existing column rather than adding a new one. In order to
+change the name you can add a "name" key into the field defining array.
+
+::
+
+	$fields = array(                         'old_name' => array(                                                          'name' => 'new_name',                                                          'type' => 'TEXT',                                                 ), ); $this->dbforge->modify_column('table_name', $fields);          // gives ALTER TABLE table_name CHANGE      old_name new_name TEXT

+Query Helper Functions
+######################
+
+$this->db->insert_id()
+=======================
+
+The insert ID number when performing database inserts.
+
+.. note:: If using the PDO driver with PostgreSQL, this function requires
+	a $name parameter, which specifies the appropriate sequence to check
+	for the insert id.
+
+$this->db->affected_rows()
+===========================
+
+Displays the number of affected rows, when doing "write" type queries
+(insert, update, etc.).
+
+.. note:: In MySQL "DELETE FROM TABLE" returns 0 affected rows. The database
+	class has a small hack that allows it to return the correct number of
+	affected rows. By default this hack is enabled but it can be turned off
+	in the database driver file.
+
+$this->db->count_all();
+========================
+
+Permits you to determine the number of rows in a particular table.
+Submit the table name in the first parameter. Example::
+
+	echo $this->db->count_all('my_table');  // Produces an integer, like 25
+
+$this->db->platform()
+=====================
+
+Outputs the database platform you are running (MySQL, MS SQL, Postgres,
+etc...)::
+
+	echo $this->db->platform();
+
+$this->db->version()
+====================
+
+Outputs the database version you are running::
+
+	echo $this->db->version();
+
+$this->db->last_query();
+=========================
+
+Returns the last query that was run (the query string, not the result).
+Example::
+
+	$str = $this->db->last_query();  // Produces:  SELECT * FROM sometable....
+
+The following two functions help simplify the process of writing
+database INSERTs and UPDATEs.
+
+$this->db->insert_string();
+============================
+
+This function simplifies the process of writing database inserts. It
+returns a correctly formatted SQL insert string. Example::
+
+	$data = array('name' => $name, 'email' => $email, 'url' => $url);  $str = $this->db->insert_string('table_name', $data);
+
+The first parameter is the table name, the second is an associative
+array with the data to be inserted. The above example produces::
+
+	INSERT INTO table_name (name, email, url) VALUES ('Rick', 'rick@example.com', 'example.com')
+
+Note: Values are automatically escaped, producing safer queries.
+
+$this->db->update_string();
+============================
+
+This function simplifies the process of writing database updates. It
+returns a correctly formatted SQL update string. Example::
+
+	$data = array('name' => $name, 'email' => $email, 'url' => $url);  $where = "author_id = 1 AND status = 'active'";  $str = $this->db->update_string('table_name', $data, $where);
+
+The first parameter is the table name, the second is an associative
+array with the data to be updated, and the third parameter is the
+"where" clause. The above example produces::
+
+	 UPDATE table_name SET name = 'Rick', email = 'rick@example.com', url = 'example.com' WHERE author_id = 1 AND status = 'active'
+
+Note: Values are automatically escaped, producing safer queries.

+#######
+Queries
+#######
+
+$this->db->query();
+===================
+
+To submit a query, use the following function::
+
+	$this->db->query('YOUR QUERY HERE');
+
+The query() function returns a database result **object** when "read"
+type queries are run, which you can use to :doc:`show your
+results <results>`. When "write" type queries are run it simply
+returns TRUE or FALSE depending on success or failure. When retrieving
+data you will typically assign the query to your own variable, like
+this::
+
+	$query = $this->db->query('YOUR QUERY HERE');
+
+$this->db->simple_query();
+===========================
+
+This is a simplified version of the $this->db->query() function. It ONLY
+returns TRUE/FALSE on success or failure. It DOES NOT return a database
+result set, nor does it set the query timer, or compile bind data, or
+store your query for debugging. It simply lets you submit a query. Most
+users will rarely use this function.
+
+***************************************
+Working with Database prefixes manually
+***************************************
+
+If you have configured a database prefix and would like to prepend it to
+a table name for use in a native SQL query for example, then you can use
+the following::
+
+	$this->db->dbprefix('tablename'); // outputs prefix_tablename
+
+
+If for any reason you would like to change the prefix programatically
+without needing to create a new connection, you can use this method::
+
+	$this->db->set_dbprefix('newprefix'); $this->db->dbprefix('tablename'); // outputs newprefix_tablename
+
+
+**********************
+Protecting identifiers
+**********************
+
+In many databases it is advisable to protect table and field names - for
+example with backticks in MySQL. **Active Record queries are
+automatically protected**, however if you need to manually protect an
+identifier you can use::
+
+	$this->db->protect_identifiers('table_name');
+
+
+This function will also add a table prefix to your table, assuming you
+have a prefix specified in your database config file. To enable the
+prefixing set TRUE (boolen) via the second parameter::
+
+	$this->db->protect_identifiers('table_name', TRUE);
+
+
+****************
+Escaping Queries
+****************
+
+It's a very good security practice to escape your data before submitting
+it into your database. CodeIgniter has three methods that help you do
+this:
+
+#. **$this->db->escape()** This function determines the data type so
+   that it can escape only string data. It also automatically adds
+   single quotes around the data so you don't have to:
+   ::
+
+	$sql = "INSERT INTO table (title) VALUES(".$this->db->escape($title).")";
+
+#. **$this->db->escape_str()** This function escapes the data passed to
+   it, regardless of type. Most of the time you'll use the above
+   function rather than this one. Use the function like this:
+   ::
+
+	$sql = "INSERT INTO table (title) VALUES('".$this->db->escape_str($title)."')";
+
+#. **$this->db->escape_like_str()** This method should be used when
+   strings are to be used in LIKE conditions so that LIKE wildcards
+   ('%', '\_') in the string are also properly escaped.
+
+::
+
+	$search = '20% raise'; $sql = "SELECT id FROM table WHERE column LIKE '%".$this->db->escape_like_str($search)."%'";
+
+
+**************
+Query Bindings
+**************
+
+Bindings enable you to simplify your query syntax by letting the system
+put the queries together for you. Consider the following example::
+
+	 $sql = "SELECT * FROM some_table WHERE id = ? AND status = ? AND author = ?";  $this->db->query($sql, array(3, 'live', 'Rick'));
+
+The question marks in the query are automatically replaced with the
+values in the array in the second parameter of the query function.
+
+The secondary benefit of using binds is that the values are
+automatically escaped, producing safer queries. You don't have to
+remember to manually escape data; the engine does it automatically for
+you.

+########################
+Generating Query Results
+########################
+
+There are several ways to generate query results:
+
+result()
+========
+
+This function returns the query result as an array of **objects**, or
+**an empty array** on failure. Typically you'll use this in a foreach
+loop, like this::
+
+	     $query = $this->db->query("YOUR QUERY");          foreach ($query->result() as $row)     {        echo $row->title;        echo $row->name;        echo $row->body;     }
+
+The above function is an alias of result_object().
+
+If you run queries that might **not** produce a result, you are
+encouraged to test the result first::
+
+	     $query = $this->db->query("YOUR QUERY");          if ($query->num_rows() > 0)     {        foreach ($query->result() as $row)        {           echo $row->title;           echo $row->name;           echo $row->body;        }     }     
+
+You can also pass a string to result() which represents a class to
+instantiate for each result object (note: this class must be loaded)
+
+::
+
+	$query = $this->db->query("SELECT * FROM users;");
+
+	foreach ($query->result('User') as $user)
+	{
+	   echo $user->name; // call attributes
+	   echo $user->reverse_name(); // or methods defined on the 'User' class
+	}
+
+result_array()
+===============
+
+This function returns the query result as a pure array, or an empty
+array when no result is produced. Typically you'll use this in a foreach
+loop, like this::
+
+	     $query = $this->db->query("YOUR QUERY");          foreach ($query->result_array() as $row)     {        echo $row['title'];        echo $row['name'];        echo $row['body'];     }
+
+row()
+=====
+
+This function returns a single result row. If your query has more than
+one row, it returns only the first row. The result is returned as an
+**object**. Here's a usage example::
+
+	     $query = $this->db->query("YOUR QUERY");          if ($query->num_rows() > 0)     {        $row = $query->row();             echo $row->title;        echo $row->name;        echo $row->body;     }     
+
+If you want a specific row returned you can submit the row number as a
+digit in the first parameter::
+
+	$row = $query->row(5);
+
+You can also add a second String parameter, which is the name of a class
+to instantiate the row with::
+
+	     $query = $this->db->query("SELECT * FROM users LIMIT 1;");          $query->row(0, 'User')     echo $row->name; // call attributes     echo $row->reverse_name(); // or methods defined on the 'User' class     
+
+row_array()
+============
+
+Identical to the above row() function, except it returns an array.
+Example::
+
+	     $query = $this->db->query("YOUR QUERY");          if ($query->num_rows() > 0)     {        $row = $query->row_array();             echo $row['title'];        echo $row['name'];        echo $row['body'];     }     
+
+If you want a specific row returned you can submit the row number as a
+digit in the first parameter::
+
+	$row = $query->row_array(5);
+
+In addition, you can walk forward/backwards/first/last through your
+results using these variations:
+
+**$row = $query->first_row()**
+ **$row = $query->last_row()**
+ **$row = $query->next_row()**
+ **$row = $query->previous_row()**
+
+By default they return an object unless you put the word "array" in the
+parameter:
+
+**$row = $query->first_row('array')**
+ **$row = $query->last_row('array')**
+ **$row = $query->next_row('array')**
+ **$row = $query->previous_row('array')**
+
+***********************
+Result Helper Functions
+***********************
+
+$query->num_rows()
+===================
+
+The number of rows returned by the query. Note: In this example, $query
+is the variable that the query result object is assigned to::
+
+	$query = $this->db->query('SELECT * FROM my_table'); echo $query->num_rows();
+
+$query->num_fields()
+=====================
+
+The number of FIELDS (columns) returned by the query. Make sure to call
+the function using your query result object::
+
+	$query = $this->db->query('SELECT * FROM my_table'); echo $query->num_fields();
+
+$query->free_result()
+======================
+
+It frees the memory associated with the result and deletes the result
+resource ID. Normally PHP frees its memory automatically at the end of
+script execution. However, if you are running a lot of queries in a
+particular script you might want to free the result after each query
+result has been generated in order to cut down on memory consumptions.
+Example::
+
+	$query = $this->db->query('SELECT title FROM my_table'); foreach ($query->result() as $row) {    echo $row->title; } $query->free_result();  // The $query result object will no longer be available  $query2 = $this->db->query('SELECT name FROM some_table'); $row = $query2->row(); echo $row->name; $query2->free_result();  // The $query2 result object will no longer be available

+############
+Transactions
+############
+
+CodeIgniter's database abstraction allows you to use transactions with
+databases that support transaction-safe table types. In MySQL, you'll
+need to be running InnoDB or BDB table types rather than the more common
+MyISAM. Most other database platforms support transactions natively.
+
+If you are not familiar with transactions we recommend you find a good
+online resource to learn about them for your particular database. The
+information below assumes you have a basic understanding of
+transactions.
+
+CodeIgniter's Approach to Transactions
+======================================
+
+CodeIgniter utilizes an approach to transactions that is very similar to
+the process used by the popular database class ADODB. We've chosen that
+approach because it greatly simplifies the process of running
+transactions. In most cases all that is required are two lines of code.
+
+Traditionally, transactions have required a fair amount of work to
+implement since they demand that you to keep track of your queries and
+determine whether to commit or rollback based on the success or failure
+of your queries. This is particularly cumbersome with nested queries. In
+contrast, we've implemented a smart transaction system that does all
+this for you automatically (you can also manage your transactions
+manually if you choose to, but there's really no benefit).
+
+Running Transactions
+====================
+
+To run your queries using transactions you will use the
+$this->db->trans_start() and $this->db->trans_complete() functions as
+follows::
+
+	 $this->db->trans_start(); $this->db->query('AN SQL QUERY...'); $this->db->query('ANOTHER QUERY...'); $this->db->query('AND YET ANOTHER QUERY...'); $this->db->trans_complete();
+
+You can run as many queries as you want between the start/complete
+functions and they will all be committed or rolled back based on success
+or failure of any given query.
+
+Strict Mode
+===========
+
+By default CodeIgniter runs all transactions in Strict Mode. When strict
+mode is enabled, if you are running multiple groups of transactions, if
+one group fails all groups will be rolled back. If strict mode is
+disabled, each group is treated independently, meaning a failure of one
+group will not affect any others.
+
+Strict Mode can be disabled as follows::
+
+	$this->db->trans_strict(FALSE);
+
+Managing Errors
+===============
+
+If you have error reporting enabled in your config/database.php file
+you'll see a standard error message if the commit was unsuccessful. If
+debugging is turned off, you can manage your own errors like this::
+
+	 $this->db->trans_start(); $this->db->query('AN SQL QUERY...'); $this->db->query('ANOTHER QUERY...'); $this->db->trans_complete();  if ($this->db->trans_status() === FALSE) {     // generate an error... or use the log_message() function to log your error }
+
+Enabling Transactions
+=====================
+
+Transactions are enabled automatically the moment you use
+$this->db->trans_start(). If you would like to disable transactions you
+can do so using $this->db->trans_off()::
+
+	 $this->db->trans_off()  $this->db->trans_start(); $this->db->query('AN SQL QUERY...'); $this->db->trans_complete();
+
+When transactions are disabled, your queries will be auto-commited, just
+as they are when running queries without transactions.
+
+Test Mode
+=========
+
+You can optionally put the transaction system into "test mode", which
+will cause your queries to be rolled back -- even if the queries produce
+a valid result. To use test mode simply set the first parameter in the
+$this->db->trans_start() function to TRUE::
+
+	 $this->db->trans_start(TRUE); // Query will be rolled back $this->db->query('AN SQL QUERY...'); $this->db->trans_complete();
+
+Running Transactions Manually
+=============================
+
+If you would like to run transactions manually you can do so as follows::
+
+	 $this->db->trans_begin();  $this->db->query('AN SQL QUERY...'); $this->db->query('ANOTHER QUERY...'); $this->db->query('AND YET ANOTHER QUERY...');    if ($this->db->trans_status() === FALSE) {     $this->db->trans_rollback(); } else {     $this->db->trans_commit(); }
+
+.. note:: Make sure to use $this->db->trans_begin() when running manual
+	transactions, **NOT** $this->db->trans_start().

+Database Utility Class
+######################
+
+The Database Utility Class contains functions that help you manage your
+database.
+
+.. contents:: Table of Contents
+
+
+******************
+Function Reference
+******************
+
+Initializing the Utility Class
+==============================
+
+.. important:: In order to initialize the Utility class, your database
+	driver must already be running, since the utilities class relies on it.
+
+Load the Utility Class as follows::
+
+	$this->load->dbutil()
+
+Once initialized you will access the functions using the $this->dbutil
+object::
+
+	$this->dbutil->some_function()
+
+$this->dbutil->list_databases()
+================================
+
+Returns an array of database names::
+
+	 $dbs = $this->dbutil->list_databases();  foreach ($dbs as $db) {     echo $db; }
+
+$this->dbutil->database_exists();
+==================================
+
+Sometimes it's helpful to know whether a particular database exists.
+Returns a boolean TRUE/FALSE. Usage example::
+
+	 if ($this->dbutil->database_exists('database_name')) {    // some code... }
+
+Note: Replace *database_name* with the name of the table you are
+looking for. This function is case sensitive.
+
+$this->dbutil->optimize_table('table_name');
+==============================================
+
+.. note:: This features is only available for MySQL/MySQLi databases.
+
+Permits you to optimize a table using the table name specified in the
+first parameter. Returns TRUE/FALSE based on success or failure::
+
+	 if ($this->dbutil->optimize_table('table_name')) {     echo 'Success!'; }
+
+.. note:: Not all database platforms support table optimization.
+
+$this->dbutil->repair_table('table_name');
+============================================
+
+.. note:: This features is only available for MySQL/MySQLi databases.
+
+Permits you to repair a table using the table name specified in the
+first parameter. Returns TRUE/FALSE based on success or failure::
+
+	 if ($this->dbutil->repair_table('table_name')) {     echo 'Success!'; }
+
+.. note:: Not all database platforms support table repairs.
+
+$this->dbutil->optimize_database();
+====================================
+
+.. note:: This features is only available for MySQL/MySQLi databases.
+
+Permits you to optimize the database your DB class is currently
+connected to. Returns an array containing the DB status messages or
+FALSE on failure.
+
+::
+
+	 $result = $this->dbutil->optimize_database();  if ($result !== FALSE) {     print_r($result); }
+
+.. note:: Not all database platforms support table optimization.
+
+$this->dbutil->csv_from_result($db_result)
+=============================================
+
+Permits you to generate a CSV file from a query result. The first
+parameter of the function must contain the result object from your
+query. Example::
+
+	 $this->load->dbutil();  $query = $this->db->query("SELECT * FROM mytable");  echo $this->dbutil->csv_from_result($query);
+
+The second, third, and fourth parameters allow you to set the delimiter
+newline, and enclosure characters respectively. By default tabs are
+used as the delimiter, "\n" is used as a new line, and a double-quote
+is used as the enclosure. Example::
+
+	$delimiter = ",";
+	$newline = "\r\n";
+	$enclosure = '"';
+
+	echo $this->dbutil->csv_from_result($query, $delimiter, $newline, $enclosure);
+
+.. important:: This function will NOT write the CSV file for you. It
+	simply creates the CSV layout. If you need to write the file
+	use the :doc:`File Helper <../helpers/file_helper>`.
+
+$this->dbutil->xml_from_result($db_result)
+=============================================
+
+Permits you to generate an XML file from a query result. The first
+parameter expects a query result object, the second may contain an
+optional array of config parameters. Example::
+
+	 $this->load->dbutil();  $query = $this->db->query("SELECT * FROM mytable");  $config = array (                   'root'    => 'root',                   'element' => 'element',                    'newline' => "\n",                    'tab'    => "\t"                 );  echo $this->dbutil->xml_from_result($query, $config);
+
+.. important:: This function will NOT write the XML file for you. It
+	simply creates the XML layout. If you need to write the file
+	use the :doc:`File Helper <../helpers/file_helper>`.
+
+$this->dbutil->backup()
+=======================
+
+Permits you to backup your full database or individual tables. The
+backup data can be compressed in either Zip or Gzip format.
+
+.. note:: This features is only available for MySQL databases.
+
+.. note:: Due to the limited execution time and memory available to PHP,
+	backing up very large databases may not be possible. If your database is
+	very large you might need to backup directly from your SQL server via
+	the command line, or have your server admin do it for you if you do not
+	have root privileges.
+
+Usage Example
+-------------
+
+::
+
+	 // Load the DB utility class $this->load->dbutil();  // Backup your entire database and assign it to a variable $backup =& $this->dbutil->backup();   // Load the file helper and write the file to your server $this->load->helper('file'); write_file('/path/to/mybackup.gz', $backup);   // Load the download helper and send the file to your desktop $this->load->helper('download'); force_download('mybackup.gz', $backup);
+
+Setting Backup Preferences
+--------------------------
+
+Backup preferences are set by submitting an array of values to the first

+Writing CodeIgniter Documentation
+#################################
+
+CodeIgniter uses Sphinx to generate its documentation in a variety of formats,
+using reStructuredText to handle the formatting.  If you are familiar with
+Markdown or Textile, you will quickly grasp reStructuredText.  The focus is
+on readability, user friendliness, and an "I've got your hand, baby" feel.
+While they can be quite technical, we always write for humans!
+
+A table of contents should always be included like the one below.
+It is created automatically by inserting the ``.. contents::``
+directive on a line by itself.
+
+.. contents:: Page Contents
+
+
+**************
+Tools Required
+**************
+
+To see the rendered HTML, ePub, PDF, etc., you will need to install Sphinx
+along with the PHP domain extension for Sphinx.  The underlying requirement
+is to have Python installed.  Lastly, you will install the CI Lexer for
+Pygments, so that code blocks can be properly highlighted.
+
+.. code-block:: bash
+
+	easy_install sphinx
+	easy_install sphinxcontrib-phpdomain
+
+Then follow the directions in the README file in the :samp:`cilexer` folder
+inside the documentation repository to install the CI Lexer.
+
+
+
+*****************************************
+Page and Section Headings and Subheadings
+*****************************************
+
+Headings not only provide order and sections within a page, but they also
+are used to automatically build both the page and document table of contents.
+Headings are formed by using certain characters as underlines for a bit of
+text.  Major headings, like page titles and section headings also use
+overlines.  Other headings just use underlines, with the following hierarchy::
+
+	# with overline for page titles
+	* with overline for major sections
+	= for subsections
+	- for subsubsections
+	^ for subsubsubsections
+	" for subsubsubsubsections (!)
+	
+The :download:`TextMate ELDocs Bundle <./ELDocs.tmbundle.zip>` can help you
+create these with the following tab triggers::
+
+	title->
+	
+		##########
+		Page Title
+		##########
+
+	sec->
+	
+		*************
+		Major Section
+		*************
+		
+	sub->
+	
+		Subsection
+		==========
+		
+	sss->
+	
+		SubSubSection
+		-------------
+		
+	ssss->
+	
+		SubSubSubSection

+		
+	sssss->
+	
+		SubSubSubSubSection (!)
+		"""""""""""""""""""""""

+###################################
+Alternate PHP Syntax for View Files
+###################################
+
+If you do not utilize CodeIgniter's :doc:`template
+engine <../libraries/parser>`, you'll be using pure PHP in your
+View files. To minimize the PHP code in these files, and to make it
+easier to identify the code blocks it is recommended that you use PHPs
+alternative syntax for control structures and short tag echo statements.
+If you are not familiar with this syntax, it allows you to eliminate the
+braces from your code, and eliminate "echo" statements.
+
+Automatic Short Tag Support
+===========================
+
+.. note:: If you find that the syntax described in this page does not
+	work on your server it might be that "short tags" are disabled in your
+	PHP ini file. CodeIgniter will optionally rewrite short tags on-the-fly,
+	allowing you to use that syntax even if your server doesn't support it.
+	This feature can be enabled in your config/config.php file.
+
+Please note that if you do use this feature, if PHP errors are
+encountered in your **view files**, the error message and line number
+will not be accurately shown. Instead, all errors will be shown as
+eval() errors.
+
+Alternative Echos
+=================
+
+Normally to echo, or print out a variable you would do this::
+
+	<?php echo $variable; ?>
+
+With the alternative syntax you can instead do it this way::
+
+	<?=$variable?>
+
+Alternative Control Structures
+==============================
+
+Controls structures, like if, for, foreach, and while can be written in
+a simplified format as well. Here is an example using foreach::
+
+	 <ul>  <?php foreach ($todo as $item): ?>  <li><?=$item?></li>  <?php endforeach; ?>  </ul>
+
+Notice that there are no braces. Instead, the end brace is replaced with
+endforeach. Each of the control structures listed above has a similar
+closing syntax: endif, endfor, endforeach, and endwhile
+
+Also notice that instead of using a semicolon after each structure
+(except the last one), there is a colon. This is important!
+
+Here is another example, using if/elseif/else. Notice the colons::
+
+	<?php if ($username == 'sally'): ?>     <h3>Hi Sally</h3>  <?php elseif ($username == 'joe'): ?>     <h3>Hi Joe</h3>  <?php else: ?>     <h3>Hi unknown user</h3>  <?php endif; ?>

+##########################
+Creating Ancillary Classes
+##########################
+
+In some cases you may want to develop classes that exist apart from your
+controllers but have the ability to utilize all of CodeIgniter's
+resources. This is easily possible as you'll see.
+
+get_instance()
+===============
+
+**Any class that you instantiate within your controller functions can
+access CodeIgniter's native resources** simply by using the
+get_instance() function. This function returns the main CodeIgniter
+object.
+
+Normally, to call any of the available CodeIgniter functions requires
+you to use the $this construct::
+
+	 $this->load->helper('url'); $this->load->library('session'); $this->config->item('base_url'); etc.
+
+$this, however, only works within your controllers, your models, or your
+views. If you would like to use CodeIgniter's classes from within your
+own custom classes you can do so as follows:
+
+First, assign the CodeIgniter object to a variable::
+
+	$CI =& get_instance();
+
+Once you've assigned the object to a variable, you'll use that variable
+*instead* of $this::
+
+	 $CI =& get_instance(); $CI->load->helper('url'); $CI->load->library('session'); $CI->config->item('base_url'); etc.
+
+.. note:: You'll notice that the above get_instance() function is being
+	passed by reference::
+
+ 		$CI =& get_instance();
+	
+	This is very important. Assigning by reference allows you to use the
+	original CodeIgniter object rather than creating a copy of it.

+######################
+Auto-loading Resources
+######################
+
+CodeIgniter comes with an "Auto-load" feature that permits libraries,
+helpers, and models to be initialized automatically every time the
+system runs. If you need certain resources globally throughout your
+application you should consider auto-loading them for convenience.
+
+The following items can be loaded automatically:
+
+-  Core classes found in the "libraries" folder
+-  Helper files found in the "helpers" folder
+-  Custom config files found in the "config" folder
+-  Language files found in the "system/language" folder
+-  Models found in the "models" folder
+
+To autoload resources, open the application/config/autoload.php file and
+add the item you want loaded to the autoload array. You'll find
+instructions in that file corresponding to each type of item.
+
+.. note:: Do not include the file extension (.php) when adding items to
+	the autoload array.

+################
+Web Page Caching
+################
+
+CodeIgniter lets you cache your pages in order to achieve maximum
+performance.
+
+Although CodeIgniter is quite fast, the amount of dynamic information
+you display in your pages will correlate directly to the server
+resources, memory, and processing cycles utilized, which affect your
+page load speeds. By caching your pages, since they are saved in their
+fully rendered state, you can achieve performance that nears that of
+static web pages.
+
+How Does Caching Work?
+======================
+
+Caching can be enabled on a per-page basis, and you can set the length
+of time that a page should remain cached before being refreshed. When a
+page is loaded for the first time, the cache file will be written to
+your application/cache folder. On subsequent page loads the cache file
+will be retrieved and sent to the requesting user's browser. If it has
+expired, it will be deleted and refreshed before being sent to the
+browser.
+
+Note: The Benchmark tag is not cached so you can still view your page
+load speed when caching is enabled.
+
+Enabling Caching
+================
+
+To enable caching, put the following tag in any of your controller
+functions::
+
+	$this->output->cache(n);
+
+Where n is the number of **minutes** you wish the page to remain cached
+between refreshes.
+
+The above tag can go anywhere within a function. It is not affected by
+the order that it appears, so place it wherever it seems most logical to
+you. Once the tag is in place, your pages will begin being cached.
+
+**Warning:** Because of the way CodeIgniter stores content for output,
+caching will only work if you are generating display for your controller
+with a :doc:`view <./views>`.
+
+.. note:: Before the cache files can be written you must set the file
+	permissions on your application/cache folder such that it is writable.
+
+Deleting Caches
+===============
+
+If you no longer wish to cache a file you can remove the caching tag and
+it will no longer be refreshed when it expires. Note: Removing the tag
+will not delete the cache immediately. It will have to expire normally.
+If you need to remove it earlier you will need to manually delete it
+from your cache folder.

+###################
+Running via the CLI
+###################
+
+As well as calling an applications :doc:`Controllers <./controllers>`
+via the URL in a browser they can also be loaded via the command-line
+interface (CLI).
+
+-  `What is the CLI? <#what>`_
+-  `Why use this method? <#why>`_
+-  `How does it work? <#how>`_
+
+What is the CLI?
+================
+
+The command-line interface is a text-based method of interacting with
+computers. For more information, check the `Wikipedia
+article <http://en.wikipedia.org/wiki/Command-line_interface>`_.
+
+Why run via the command-line?
+=============================
+
+There are many reasons for running CodeIgniter from the command-line,
+but they are not always obvious.
+
+-  Run your cron-jobs without needing to use wget or curl
+-  Make your cron-jobs inaccessible from being loaded in the URL by
+   checking for ``$this->input->is_cli_request()``
+-  Make interactive "tasks" that can do things like set permissions,
+   prune cache folders, run backups, etc.
+-  Integrate with other applications in other languages. For example, a
+   random C++ script could call one command and run code in your models!
+
+Let's try it: Hello World!
+==========================
+
+Let's create a simple controller so you can see it in action. Using your
+text editor, create a file called tools.php, and put the following code
+in it:
+
+<?php class Tools extends CI_Controller { public function message($to =
+'World') { echo "Hello {$to}!".PHP_EOL; } } ?>
+Then save the file to your application/controllers/ folder.
+
+Now normally you would visit the your site using a URL similar to this::
+
+	example.com/index.php/tools/message/to
+
+Instead, we are going to open Terminal in Mac/Lunix or go to Run > "cmd"
+in Windows and navigate to our CodeIgniter project.
+
+	$ cd /path/to/project;
+	$ php index.php tools message
+
+If you did it right, you should see Hello World!.
+
+	$ php index.php tools message "John Smith"
+
+Here we are passing it a argument in the same way that URL parameters
+work. "John Smith" is passed as a argument and output is: Hello John
+Smith!.
+
+That's it!
+==========
+
+That, in a nutshell, is all there is to know about controllers on the
+command line. Remember that this is just a normal controller, so routing
+and _remap works fine.

+################
+Common Functions
+################
+
+CodeIgniter uses a few functions for its operation that are globally
+defined, and are available to you at any point. These do not require
+loading any libraries or helpers.
+
+is_php('version_number')
+==========================
+
+is_php() determines of the PHP version being used is greater than the
+supplied version_number.
+
+::
+
+	if (is_php('5.3.0')) {     $str = quoted_printable_encode($str); }
+
+Returns boolean TRUE if the installed version of PHP is equal to or
+greater than the supplied version number. Returns FALSE if the installed
+version of PHP is lower than the supplied version number.
+
+is_really_writable('path/to/file')
+====================================
+
+is_writable() returns TRUE on Windows servers when you really can't
+write to the file as the OS reports to PHP as FALSE only if the
+read-only attribute is marked. This function determines if a file is
+actually writable by attempting to write to it first. Generally only
+recommended on platforms where this information may be unreliable.
+
+::
+
+	if (is_really_writable('file.txt')) {     echo "I could write to this if I wanted to"; } else {     echo "File is not writable"; }
+
+config_item('item_key')
+=========================
+
+The :doc:`Config library <../libraries/config>` is the preferred way of
+accessing configuration information, however config_item() can be used
+to retrieve single keys. See Config library documentation for more
+information.
+
+show_error('message'), show_404('page'), log_message('level',
+'message')
+==========
+
+These are each outlined on the :doc:`Error Handling <errors>` page.
+
+set_status_header(code, 'text');
+==================================
+
+Permits you to manually set a server status header. Example::
+
+	set_status_header(401); // Sets the header as:  Unauthorized
+
+`See here <http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html>`_ for
+a full list of headers.
+
+remove_invisible_characters($str)
+===================================
+
+This function prevents inserting null characters between ascii
+characters, like Java\\0script.
+
+html_escape($mixed)
+====================
+
+This function provides short cut for htmlspecialchars() function. It
+accepts string and array. To prevent Cross Site Scripting (XSS), it is
+very useful.

+
+What is a Controller?
+=====================
+
+A Controller is simply a class file that is named in a way that can be
+associated with a URI.
+
+Consider this URI::
+
+	example.com/index.php/blog/
+
+In the above example, CodeIgniter would attempt to find a controller
+named blog.php and load it.
+
+**When a controller's name matches the first segment of a URI, it will
+be loaded.**
+
+Let's try it: Hello World!
+==========================
+
+Let's create a simple controller so you can see it in action. Using your
+text editor, create a file called blog.php, and put the following code
+in it:
+
+<?php class Blog extends CI_Controller { public function index() { echo
+'Hello World!'; } } ?>
+Then save the file to your application/controllers/ folder.
+
+Now visit the your site using a URL similar to this::
+
+	example.com/index.php/blog/
+
+If you did it right, you should see Hello World!.
+
+Note: Class names must start with an uppercase letter. In other words,
+this is valid::
+
+	<?php class Blog extends CI_Controller {  } ?>
+
+This is **not** valid::
+
+	<?php class blog extends CI_Controller {  } ?>
+
+Also, always make sure your controller extends the parent controller
+class so that it can inherit all its functions.
+
+Functions
+=========
+
+In the above example the function name is index(). The "index" function
+is always loaded by default if the **second segment** of the URI is
+empty. Another way to show your "Hello World" message would be this::
+
+	example.com/index.php/blog/index/
+
+**The second segment of the URI determines which function in the
+controller gets called.**
+
+Let's try it. Add a new function to your controller:
+
+<?php class Blog extends CI_Controller { public function index() { echo
+'Hello World!'; } public function comments() { echo 'Look at this!'; } }
+?>
+Now load the following URL to see the comment function::
+
+	example.com/index.php/blog/comments/
+
+You should see your new message.
+
+Passing URI Segments to your Functions
+======================================
+
+If your URI contains more then two segments they will be passed to your
+function as parameters.
+
+For example, lets say you have a URI like this::
+
+	example.com/index.php/products/shoes/sandals/123
+
+Your function will be passed URI segments 3 and 4 ("sandals" and "123")::
+
+	 <?php class Products extends CI_Controller {      public function shoes($sandals, $id)     {         echo $sandals;         echo $id;     } } ?>
+
+.. important:: If you are using the :doc:`URI Routing <routing>`
+	feature, the segments passed to your function will be the re-routed
+	ones.
+
+Defining a Default Controller
+=============================
+
+CodeIgniter can be told to load a default controller when a URI is not
+present, as will be the case when only your site root URL is requested.
+To specify a default controller, open your application/config/routes.php
+file and set this variable::
+
+	$route['default_controller'] = 'Blog';
+
+Where Blog is the name of the controller class you want used. If you now
+load your main index.php file without specifying any URI segments you'll
+see your Hello World message by default.
+
+Remapping Function Calls
+========================
+
+As noted above, the second segment of the URI typically determines which
+function in the controller gets called. CodeIgniter permits you to
+override this behavior through the use of the _remap() function::
+
+	public function _remap() {     // Some code here... }
+
+.. important:: If your controller contains a function named _remap(),
+	it will **always** get called regardless of what your URI contains. It
+	overrides the normal behavior in which the URI determines which function
+	is called, allowing you to define your own function routing rules.
+
+The overridden function call (typically the second segment of the URI)
+will be passed as a parameter to the _remap() function::
+
+	public function _remap($method) {     if ($method == 'some_method')     {         $this->$method();     }     else     {         $this->default_method();     } }
+
+Any extra segments after the method name are passed into _remap() as an
+optional second parameter. This array can be used in combination with
+PHP's `call_user_func_array <http://php.net/call_user_func_array>`_
+to emulate CodeIgniter's default behavior.
+
+::
+
+	public function _remap($method, $params = array()) {     $method = 'process_'.$method;     if (method_exists($this, $method))     {         return call_user_func_array(array($this, $method), $params);     }     show_404(); }
+
+Processing Output
+=================
+
+CodeIgniter has an output class that takes care of sending your final
+rendered data to the web browser automatically. More information on this
+can be found in the :doc::doc:`Views <views>` and `Output
+class <../libraries/output>` pages. In some cases, however, you
+might want to post-process the finalized data in some way and send it to
+the browser yourself. CodeIgniter permits you to add a function named
+_output() to your controller that will receive the finalized output
+data.
+
+.. important:: If your controller contains a function named _output(),
+	it will **always** be called by the output class instead of echoing the
+	finalized data directly. The first parameter of the function will
+	contain the finalized output.
+
+Here is an example::
+
+	 public function _output($output) {     echo $output; }
+
+Please note that your _output() function will receive the data in its
+finalized state. Benchmark and memory usage data will be rendered, cache
+files written (if you have caching enabled), and headers will be sent
+(if you use that :doc:`feature <../libraries/output>`) before it is
+handed off to the _output() function.
+To have your controller's output cached properly, its _output() method
+can use::
+
+	if ($this->output->cache_expiration > 0) {     $this->output->_write_cache($output); }
+
+If you are using this feature the page execution timer and memory usage
+stats might not be perfectly accurate since they will not take into
+acccount any further processing you do. For an alternate way to control
+output *before* any of the final processing is done, please see the
+available methods in the :doc:`Output Class <../libraries/output>`.
+
+Private Functions
+=================
+
+In some cases you may want certain functions hidden from public access.
+To make a function private, simply add an underscore as the name prefix
+and it will not be served via a URL request. For example, if you were to
+have a function like this::
+
+	 private function _utility() {   // some code }
+
+Trying to access it via the URL, like this, will not work::
+
+	example.com/index.php/blog/_utility/
+
+Organizing Your Controllers into Sub-folders
+============================================
+
+If you are building a large application you might find it convenient to
+organize your controllers into sub-folders. CodeIgniter permits you to
+do this.
+
+Simply create folders within your application/controllers directory and
+place your controller classes within them.
+
+.. note:: When using this feature the first segment of your URI must
+	specify the folder. For example, lets say you have a controller located
+	here::
+
+		application/controllers/products/shoes.php
+
+	To call the above controller your URI will look something like this::
+
+		example.com/index.php/products/shoes/show/123
+
+Each of your sub-folders may contain a default controller which will be
+called if the URL contains only the sub-folder. Simply name your default
+controller as specified in your application/config/routes.php file
+
+CodeIgniter also permits you to remap your URIs using its :doc:`URI
+Routing <routing>` feature.
+
+Class Constructors
+==================
+
+If you intend to use a constructor in any of your Controllers, you
+**MUST** place the following line of code in it::
+
+	parent::__construct();
+
+The reason this line is necessary is because your local constructor will
+be overriding the one in the parent controller class so we need to
+manually call it.
+
+::
+
+	 <?php class Blog extends CI_Controller {         public function __construct()        {             parent::__construct();             // Your own constructor code        } } ?>
+
+Constructors are useful if you need to set some default values, or run a
+default process when your class is instantiated. Constructors can't
+return a value, but they can do some default work.
+
+Reserved Function Names
+=======================
+
+Since your controller classes will extend the main application
+controller you must be careful not to name your functions identically to
+the ones used by that class, otherwise your local functions will
+override them. See :doc:`Reserved Names <reserved_names>` for a full
+list.
+
+That's it!
+==========
+
+That, in a nutshell, is all there is to know about controllers.

+############################
+Creating Core System Classes
+############################
+
+Every time CodeIgniter runs there are several base classes that are
+initialized automatically as part of the core framework. It is possible,
+however, to swap any of the core system classes with your own versions
+or even extend the core versions.
+
+**Most users will never have any need to do this, but the option to
+replace or extend them does exist for those who would like to
+significantly alter the CodeIgniter core.**
+
+.. note:: Messing with a core system class has a lot of implications, so
+	make sure you know what you are doing before attempting it.
+
+System Class List
+=================
+
+The following is a list of the core system files that are invoked every
+time CodeIgniter runs:
+
+-  Benchmark
+-  Config
+-  Controller
+-  Exceptions
+-  Hooks
+-  Input
+-  Language
+-  Loader
+-  Log
+-  Output
+-  Router
+-  URI
+-  Utf8
+
+Replacing Core Classes
+======================
+
+To use one of your own system classes instead of a default one simply
+place your version inside your local application/core directory::
+
+	application/core/some-class.php
+
+If this directory does not exist you can create it.
+
+Any file named identically to one from the list above will be used
+instead of the one normally used.
+
+Please note that your class must use CI as a prefix. For example, if
+your file is named Input.php the class will be named::
+
+	 class CI_Input {  }
+
+Extending Core Class
+====================
+
+If all you need to do is add some functionality to an existing library -
+perhaps add a function or two - then it's overkill to replace the entire
+library with your version. In this case it's better to simply extend the
+class. Extending a class is nearly identical to replacing a class with a
+couple exceptions:
+
+-  The class declaration must extend the parent class.
+-  Your new class name and filename must be prefixed with MY\_ (this
+   item is configurable. See below.).
+
+For example, to extend the native Input class you'll create a file named
+application/core/MY_Input.php, and declare your class with::
+
+	 class MY_Input extends CI_Input {  }
+
+Note: If you need to use a constructor in your class make sure you
+extend the parent constructor::
+
+	 class MY_Input extends CI_Input {      function __construct()     {         parent::__construct();     } }
+
+**Tip:** Any functions in your class that are named identically to the
+functions in the parent class will be used instead of the native ones
+(this is known as "method overriding"). This allows you to substantially
+alter the CodeIgniter core.
+
+If you are extending the Controller core class, then be sure to extend
+your new class in your application controller's constructors.
+
+::
+
+	class Welcome extends MY_Controller {      function __construct()     {         parent::__construct();     }      function index()     {         $this->load->view('welcome_message');     } }
+
+Setting Your Own Prefix
+-----------------------
+
+To set your own sub-class prefix, open your
+application/config/config.php file and look for this item::
+
+	$config['subclass_prefix'] = 'MY_';
+
+Please note that all native CodeIgniter libraries are prefixed with CI\_
+so DO NOT use that as your prefix.

+##################
+Creating Libraries
+##################
+
+When we use the term "Libraries" we are normally referring to the
+classes that are located in the libraries directory and described in the
+Class Reference of this user guide. In this case, however, we will
+instead describe how you can create your own libraries within your
+application/libraries directory in order to maintain separation between
+your local resources and the global framework resources.
+
+As an added bonus, CodeIgniter permits your libraries to extend native
+classes if you simply need to add some functionality to an existing
+library. Or you can even replace native libraries just by placing
+identically named versions in your application/libraries folder.
+
+In summary:
+
+-  You can create entirely new libraries.
+-  You can extend native libraries.
+-  You can replace native libraries.
+
+The page below explains these three concepts in detail.
+
+.. note:: The Database classes can not be extended or replaced with your
+	own classes. All other classes are able to be replaced/extended.
+
+Storage
+=======
+
+Your library classes should be placed within your application/libraries
+folder, as this is where CodeIgniter will look for them when they are
+initialized.
+
+Naming Conventions
+==================
+
+-  File names must be capitalized. For example: Myclass.php
+-  Class declarations must be capitalized. For example: class Myclass
+-  Class names and file names must match.
+
+The Class File
+==============
+
+Classes should have this basic prototype (Note: We are using the name
+Someclass purely as an example)::
+
+	<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');  class Someclass {      public function some_function()     {     } } /* End of file Someclass.php */
+
+Using Your Class
+================
+
+From within any of your :doc:`Controller <controllers>` functions you
+can initialize your class using the standard::
+
+	$this->load->library('someclass');
+
+Where *someclass* is the file name, without the ".php" file extension.
+You can submit the file name capitalized or lower case. CodeIgniter
+doesn't care.
+
+Once loaded you can access your class using the lower case version::
+
+	$this->someclass->some_function();  // Object instances will always be lower case
+
+Passing Parameters When Initializing Your Class
+===============================================
+
+In the library loading function you can dynamically pass data as an
+array via the second parameter and it will be passed to your class
+constructor::
+
+	 $params = array('type' => 'large', 'color' => 'red');  $this->load->library('Someclass', $params);
+
+If you use this feature you must set up your class constructor to expect
+data::
+
+	<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');  class Someclass {      public function __construct($params)     {         // Do something with $params     } } ?>
+
+You can also pass parameters stored in a config file. Simply create a
+config file named identically to the class file name and store it in
+your application/config/ folder. Note that if you dynamically pass
+parameters as described above, the config file option will not be
+available.
+
+Utilizing CodeIgniter Resources within Your Library
+===================================================
+
+To access CodeIgniter's native resources within your library use the
+get_instance() function. This function returns the CodeIgniter super
+object.
+
+Normally from within your controller functions you will call any of the
+available CodeIgniter functions using the $this construct::
+
+	 $this->load->helper('url'); $this->load->library('session'); $this->config->item('base_url'); etc.
+
+$this, however, only works directly within your controllers, your
+models, or your views. If you would like to use CodeIgniter's classes
+from within your own custom classes you can do so as follows:
+
+First, assign the CodeIgniter object to a variable::
+
+	$CI =& get_instance();
+
+Once you've assigned the object to a variable, you'll use that variable
+*instead* of $this::
+
+	 $CI =& get_instance();  $CI->load->helper('url'); $CI->load->library('session'); $CI->config->item('base_url'); etc.
+
+.. note:: You'll notice that the above get_instance() function is being
+	passed by reference::
+	
+		$CI =& get_instance();
+
+	This is very important. Assigning by reference allows you to use the
+	original CodeIgniter object rather than creating a copy of it.
+
+Replacing Native Libraries with Your Versions
+=============================================
+
+Simply by naming your class files identically to a native library will
+cause CodeIgniter to use it instead of the native one. To use this
+feature you must name the file and the class declaration exactly the
+same as the native library. For example, to replace the native Email
+library you'll create a file named application/libraries/Email.php, and
+declare your class with::
+
+	 class CI_Email {  }
+
+Note that most native classes are prefixed with CI\_.
+
+To load your library you'll see the standard loading function::
+
+	$this->load->library('email');
+
+.. note:: At this time the Database classes can not be replaced with
+	your own versions.
+
+Extending Native Libraries
+==========================
+
+If all you need to do is add some functionality to an existing library -
+perhaps add a function or two - then it's overkill to replace the entire
+library with your version. In this case it's better to simply extend the
+class. Extending a class is nearly identical to replacing a class with a
+couple exceptions:
+
+-  The class declaration must extend the parent class.
+-  Your new class name and filename must be prefixed with MY\_ (this
+   item is configurable. See below.).
+
+For example, to extend the native Email class you'll create a file named
+application/libraries/MY_Email.php, and declare your class with::
+
+	 class MY_Email extends CI_Email {  }
+
+Note: If you need to use a constructor in your class make sure you
+extend the parent constructor::
+
+	 class MY_Email extends CI_Email {      public function __construct()     {         parent::__construct();     } }
+
+Loading Your Sub-class
+----------------------
+
+To load your sub-class you'll use the standard syntax normally used. DO
+NOT include your prefix. For example, to load the example above, which
+extends the Email class, you will use::
+
+	$this->load->library('email');
+
+Once loaded you will use the class variable as you normally would for
+the class you are extending. In the case of the email class all calls
+will use::
+
+	$this->email->some_function();
+
+Setting Your Own Prefix
+-----------------------
+
+To set your own sub-class prefix, open your
+application/config/config.php file and look for this item::
+
+	$config['subclass_prefix'] = 'MY_';
+
+Please note that all native CodeIgniter libraries are prefixed with CI\_
+so DO NOT use that as your prefix.

+#########################
+Using CodeIgniter Drivers
+#########################
+
+Drivers are a special type of Library that has a parent class and any
+number of potential child classes. Child classes have access to the
+parent class, but not their siblings. Drivers provide an elegant syntax
+in your :doc:`controllers <controllers>` for libraries that benefit
+from or require being broken down into discrete classes.
+
+Drivers are found in the system/libraries folder, in their own folder
+which is identically named to the parent library class. Also inside that
+folder is a subfolder named drivers, which contains all of the possible
+child class files.
+
+To use a driver you will initialize it within a controller using the
+following initialization function::
+
+	$this->load->driver('class name'); 
+
+Where class name is the name of the driver class you want to invoke. For
+example, to load a driver named "Some Parent" you would do this::
+
+	$this->load->driver('some_parent');
+
+Methods of that class can then be invoked with::
+
+	$this->some_parent->some_method();
+
+The child classes, the drivers themselves, can then be called directly
+through the parent class, without initializing them::
+
+	$this->some_parent->child_one->some_method(); $this->some_parent->child_two->another_method();
+
+Creating Your Own Drivers
+=========================
+
+Please read the section of the user guide that discusses how to :doc:`create
+your own drivers <creating_drivers>`.

+##############################
+Handling Multiple Environments
+##############################
+
+Developers often desire different system behavior depending on whether
+an application is running in a development or production environment.
+For example, verbose error output is something that would be useful
+while developing an application, but it may also pose a security issue
+when "live".
+
+The ENVIRONMENT Constant
+========================
+
+By default, CodeIgniter comes with the environment constant set to
+'development'. At the top of index.php, you will see::
+
+	 define('ENVIRONMENT', 'development');
+
+In addition to affecting some basic framework behavior (see the next
+section), you may use this constant in your own development to
+differentiate between which environment you are running in.
+
+Effects On Default Framework Behavior
+=====================================
+
+There are some places in the CodeIgniter system where the ENVIRONMENT
+constant is used. This section describes how default framework behavior
+is affected.
+
+Error Reporting
+---------------
+
+Setting the ENVIRONMENT constant to a value of 'development' will cause
+all PHP errors to be rendered to the browser when they occur.
+Conversely, setting the constant to 'production' will disable all error
+output. Disabling error reporting in production is a :doc:`good security
+practice <security>`.
+
+Configuration Files
+-------------------
+
+Optionally, you can have CodeIgniter load environment-specific
+configuration files. This may be useful for managing things like
+differing API keys across multiple environments. This is described in
+more detail in the environment section of the `Config
+Class <../libraries/config.html#environments>`_ documentation.

+##############
+Error Handling
+##############
+
+CodeIgniter lets you build error reporting into your applications using
+the functions described below. In addition, it has an error logging
+class that permits error and debugging messages to be saved as text
+files.
+
+.. note:: By default, CodeIgniter displays all PHP errors. You might
+	wish to change this behavior once your development is complete. You'll
+	find the error_reporting() function located at the top of your main
+	index.php file. Disabling error reporting will NOT prevent log files
+	from being written if there are errors.
+
+Unlike most systems in CodeIgniter, the error functions are simple
+procedural interfaces that are available globally throughout the
+application. This approach permits error messages to get triggered
+without having to worry about class/function scoping.
+
+The following functions let you generate errors:
+
+show_error('message' [, int $status_code= 500 ] )
+===================================================
+
+This function will display the error message supplied to it using the
+following error template:
+
+application/errors/error_general.php
+
+The optional parameter $status_code determines what HTTP status code
+should be sent with the error.
+
+show_404('page' [, 'log_error'])
+==================================
+
+This function will display the 404 error message supplied to it using
+the following error template:
+
+application/errors/error_404.php
+
+The function expects the string passed to it to be the file path to the
+page that isn't found. Note that CodeIgniter automatically shows 404
+messages if controllers are not found.
+
+CodeIgniter automatically logs any show_404() calls. Setting the
+optional second parameter to FALSE will skip logging.
+
+log_message('level', 'message')
+================================
+
+This function lets you write messages to your log files. You must supply
+one of three "levels" in the first parameter, indicating what type of
+message it is (debug, error, info), with the message itself in the
+second parameter. Example::
+
+	 if ($some_var == "") {     log_message('error', 'Some variable did not contain a value.'); } else {     log_message('debug', 'Some variable was correctly set'); }  log_message('info', 'The purpose of some variable is to provide some value.');
+
+There are three message types:
+
+#. Error Messages. These are actual errors, such as PHP errors or user
+   errors.
+#. Debug Messages. These are messages that assist in debugging. For
+   example, if a class has been initialized, you could log this as
+   debugging info.
+#. Informational Messages. These are the lowest priority messages,
+   simply giving information regarding some process. CodeIgniter doesn't
+   natively generate any info messages but you may want to in your
+   application.
+
+.. note:: In order for the log file to actually be written, the "logs"
+	folder must be writable. In addition, you must set the "threshold" for
+	logging in application/config/config.php. You might, for example, only
+	want error messages to be logged, and not the other two types. If you
+	set it to zero logging will be disabled.

+################
+Helper Functions
+################
+
+Helpers, as the name suggests, help you with tasks. Each helper file is
+simply a collection of functions in a particular category. There are URL
+Helpers, that assist in creating links, there are Form Helpers that help
+you create form elements, Text Helpers perform various text formatting
+routines, Cookie Helpers set and read cookies, File Helpers help you
+deal with files, etc.
+
+Unlike most other systems in CodeIgniter, Helpers are not written in an
+Object Oriented format. They are simple, procedural functions. Each
+helper function performs one specific task, with no dependence on other
+functions.
+
+CodeIgniter does not load Helper Files by default, so the first step in
+using a Helper is to load it. Once loaded, it becomes globally available
+in your :doc:`controller <../general/controllers>` and
+:doc:`views <../general/views>`.
+
+Helpers are typically stored in your system/helpers, or
+application/helpers directory. CodeIgniter will look first in your
+application/helpers directory. If the directory does not exist or the
+specified helper is not located there CI will instead look in your
+global system/helpers folder.
+
+Loading a Helper
+================
+
+Loading a helper file is quite simple using the following function::
+
+	$this->load->helper('name');
+
+Where name is the file name of the helper, without the .php file
+extension or the "helper" part.
+
+For example, to load the URL Helper file, which is named
+url_helper.php, you would do this::
+
+	$this->load->helper('url');
+
+A helper can be loaded anywhere within your controller functions (or
+even within your View files, although that's not a good practice), as
+long as you load it before you use it. You can load your helpers in your
+controller constructor so that they become available automatically in
+any function, or you can load a helper in a specific function that needs
+it.
+
+Note: The Helper loading function above does not return a value, so
+don't try to assign it to a variable. Just use it as shown.
+
+Loading Multiple Helpers
+========================
+
+If you need to load more than one helper you can specify them in an
+array, like this::
+
+	$this->load->helper( array('helper1', 'helper2', 'helper3') );
+
+Auto-loading Helpers
+====================
+
+If you find that you need a particular helper globally throughout your
+application, you can tell CodeIgniter to auto-load it during system
+initialization. This is done by opening the
+application/config/autoload.php file and adding the helper to the
+autoload array.
+
+Using a Helper
+==============
+
+Once you've loaded the Helper File containing the function you intend to
+use, you'll call it the way you would a standard PHP function.
+
+For example, to create a link using the anchor() function in one of your
+view files you would do this::
+
+	<?php echo anchor('blog/comments', 'Click Here');?>
+
+Where "Click Here" is the name of the link, and "blog/comments" is the
+URI to the controller/function you wish to link to.
+
+"Extending" Helpers
+===================
+
+To "extend" Helpers, create a file in your application/helpers/ folder
+with an identical name to the existing Helper, but prefixed with MY\_
+(this item is configurable. See below.).
+
+If all you need to do is add some functionality to an existing helper -
+perhaps add a function or two, or change how a particular helper
+function operates - then it's overkill to replace the entire helper with
+your version. In this case it's better to simply "extend" the Helper.
+The term "extend" is used loosely since Helper functions are procedural
+and discrete and cannot be extended in the traditional programmatic
+sense. Under the hood, this gives you the ability to add to the
+functions a Helper provides, or to modify how the native Helper
+functions operate.
+
+For example, to extend the native Array Helper you'll create a file
+named application/helpers/MY_array_helper.php, and add or override
+functions::
+
+	 // any_in_array() is not in the Array Helper, so it defines a new function function any_in_array($needle, $haystack) {     $needle = (is_array($needle)) ? $needle : array($needle);          foreach ($needle as $item)     {         if (in_array($item, $haystack))         {             return TRUE;         }         }          return FALSE; }  // random_element() is included in Array Helper, so it overrides the native function function random_element($array) {     shuffle($array);     return array_pop($array); }
+
+Setting Your Own Prefix
+-----------------------
+
+The filename prefix for "extending" Helpers is the same used to extend
+libraries and Core classes. To set your own prefix, open your
+application/config/config.php file and look for this item::
+
+	$config['subclass_prefix'] = 'MY_';
+
+Please note that all native CodeIgniter libraries are prefixed with CI\_
+so DO NOT use that as your prefix.
+
+Now What?
+=========
+
+In the Table of Contents you'll find a list of all the available Helper
+Files. Browse each one to see what they do.

+####################################
+Hooks - Extending the Framework Core
+####################################
+
+CodeIgniter's Hooks feature provides a means to tap into and modify the
+inner workings of the framework without hacking the core files. When
+CodeIgniter runs it follows a specific execution process, diagramed in
+the :doc:`Application Flow <../overview/appflow>` page. There may be
+instances, however, where you'd like to cause some action to take place
+at a particular stage in the execution process. For example, you might
+want to run a script right before your controllers get loaded, or right
+after, or you might want to trigger one of your own scripts in some
+other location.
+
+Enabling Hooks
+==============
+
+The hooks feature can be globally enabled/disabled by setting the
+following item in the application/config/config.php file::
+
+	$config['enable_hooks'] = TRUE;
+
+Defining a Hook
+===============
+
+Hooks are defined in application/config/hooks.php file. Each hook is
+specified as an array with this prototype::
+
+	 $hook['pre_controller'] = array(                                 'class'    => 'MyClass',                                 'function' => 'Myfunction',                                 'filename' => 'Myclass.php',                                 'filepath' => 'hooks',                                 'params'   => array('beer', 'wine', 'snacks')                                 );
+
+**Notes:**
+The array index correlates to the name of the particular hook point you
+want to use. In the above example the hook point is pre_controller. A
+list of hook points is found below. The following items should be
+defined in your associative hook array:
+
+-  **class** The name of the class you wish to invoke. If you prefer to
+   use a procedural function instead of a class, leave this item blank.
+-  **function** The function name you wish to call.
+-  **filename** The file name containing your class/function.
+-  **filepath** The name of the directory containing your script. Note:
+   Your script must be located in a directory INSIDE your application
+   folder, so the file path is relative to that folder. For example, if
+   your script is located in application/hooks, you will simply use
+   hooks as your filepath. If your script is located in
+   application/hooks/utilities you will use hooks/utilities as your
+   filepath. No trailing slash.
+-  **params** Any parameters you wish to pass to your script. This item
+   is optional.
+
+Multiple Calls to the Same Hook
+===============================
+
+If want to use the same hook point with more then one script, simply
+make your array declaration multi-dimensional, like this::
+
+	 $hook['pre_controller'][] = array(                                 'class'    => 'MyClass',                                 'function' => 'Myfunction',                                 'filename' => 'Myclass.php',                                 'filepath' => 'hooks',                                 'params'   => array('beer', 'wine', 'snacks')                                 );  $hook['pre_controller'][] = array(                                 'class'    => 'MyOtherClass',                                 'function' => 'MyOtherfunction',                                 'filename' => 'Myotherclass.php',                                 'filepath' => 'hooks',                                 'params'   => array('red', 'yellow', 'blue')                                 );
+
+Notice the brackets after each array index::
+
+	$hook['pre_controller'][]
+
+This permits you to have the same hook point with multiple scripts. The
+order you define your array will be the execution order.
+
+Hook Points
+===========
+
+The following is a list of available hook points.
+
+-  **pre_system**
+   Called very early during system execution. Only the benchmark and
+   hooks class have been loaded at this point. No routing or other
+   processes have happened.
+-  **pre_controller**
+   Called immediately prior to any of your controllers being called.
+   All base classes, routing, and security checks have been done.
+-  **post_controller_constructor**
+   Called immediately after your controller is instantiated, but prior
+   to any method calls happening.
+-  **post_controller**
+   Called immediately after your controller is fully executed.
+-  **display_override**
+   Overrides the _display() function, used to send the finalized page
+   to the web browser at the end of system execution. This permits you
+   to use your own display methodology. Note that you will need to
+   reference the CI superobject with $this->CI =& get_instance() and
+   then the finalized data will be available by calling
+   $this->CI->output->get_output()
+-  **cache_override**
+   Enables you to call your own function instead of the
+   _display_cache() function in the output class. This permits you to
+   use your own cache display mechanism.
+-  **post_system**
+   Called after the final rendered page is sent to the browser, at the
+   end of system execution after the finalized data is sent to the
+   browser.

+###########################
+Using CodeIgniter Libraries
+###########################
+
+All of the available libraries are located in your system/libraries
+folder. In most cases, to use one of these classes involves initializing
+it within a :doc:`controller <controllers>` using the following
+initialization function::
+
+	$this->load->library('class name'); 
+
+Where class name is the name of the class you want to invoke. For
+example, to load the form validation class you would do this::
+
+	$this->load->library('form_validation'); 
+
+Once initialized you can use it as indicated in the user guide page
+corresponding to that class.
+
+Additionally, multiple libraries can be loaded at the same time by
+passing an array of libraries to the load function.
+
+::
+
+	$this->load->library(array('email', 'table'));
+
+Creating Your Own Libraries
+===========================
+
+Please read the section of the user guide that discusses how to :doc:`create
+your own libraries <creating_libraries>`

+##########################
+Managing your Applications
+##########################
+
+By default it is assumed that you only intend to use CodeIgniter to
+manage one application, which you will build in your application/
+directory. It is possible, however, to have multiple sets of
+applications that share a single CodeIgniter installation, or even to
+rename or relocate your application folder.
+
+Renaming the Application Folder
+===============================
+
+If you would like to rename your application folder you may do so as
+long as you open your main index.php file and set its name using the
+$application_folder variable::
+
+	$application_folder = "application";
+
+Relocating your Application Folder
+==================================
+
+It is possible to move your application folder to a different location
+on your server than your system folder. To do so open your main
+index.php and set a *full server path* in the $application_folder
+variable.
+
+::
+
+	$application_folder = "/Path/to/your/application";
+
+Running Multiple Applications with one CodeIgniter Installation
+===============================================================
+
+If you would like to share a common CodeIgniter installation to manage
+several different applications simply put all of the directories located
+inside your application folder into their own sub-folder.
+
+For example, let's say you want to create two applications, "foo" and
+"bar". You could structure your application folders like this::
+
+	applications/foo/ applications/foo/config/ applications/foo/controllers/ applications/foo/errors/ applications/foo/libraries/ applications/foo/models/ applications/foo/views/ applications/bar/ applications/bar/config/ applications/bar/controllers/ applications/bar/errors/ applications/bar/libraries/ applications/bar/models/ applications/bar/views/
+
+To select a particular application for use requires that you open your
+main index.php file and set the $application_folder variable. For
+example, to select the "foo" application for use you would do this::
+
+	$application_folder = "applications/foo";
+
+.. note:: Each of your applications will need its own index.php file
+	which calls the desired application. The index.php file can be named
+	anything you want.

+Models
+######
+
+Models are **optionally** available for those who want to use a more
+traditional MVC approach.

+-  `Loading a Model <#loading>`_
+-  `Auto-Loading a Model <#auto_load_model>`_
+-  `Connecting to your Database <#conn>`_
+
+What is a Model?
+================
+
+Models are PHP classes that are designed to work with information in
+your database. For example, let's say you use CodeIgniter to manage a
+blog. You might have a model class that contains functions to insert,
+update, and retrieve your blog data. Here is an example of what such a
+model class might look like::
+
+	 class Blogmodel extends CI_Model {      var $title   = '';     var $content = '';     var $date    = '';      function __construct()     {         // Call the Model constructor         parent::__construct();     }          function get_last_ten_entries()     {         $query = $this->db->get('entries', 10);         return $query->result();     }      function insert_entry()     {         $this->title   = $_POST['title']; // please read the below note         $this->content = $_POST['content'];         $this->date    = time();          $this->db->insert('entries', $this);     }      function update_entry()     {         $this->title   = $_POST['title'];         $this->content = $_POST['content'];         $this->date    = time();          $this->db->update('entries', $this, array('id' => $_POST['id']));     }  }
+
+Note: The functions in the above example use the :doc:`Active
+Record <../database/active_record>` database functions.
+
+.. note:: For the sake of simplicity in this example we're using $_POST
+	directly. This is generally bad practice, and a more common approach
+	would be to use the :doc:`Input Class <../libraries/input>`
+	$this->input->post('title')
+
+Anatomy of a Model
+==================
+
+Model classes are stored in your application/models/ folder. They can be
+nested within sub-folders if you want this type of organization.
+
+The basic prototype for a model class is this::
+
+	 class Model_name extends CI_Model {      function __construct()     {         parent::__construct();     } }
+
+Where Model_name is the name of your class. Class names **must** have
+the first letter capitalized with the rest of the name lowercase. Make
+sure your class extends the base Model class.
+
+The file name will be a lower case version of your class name. For
+example, if your class is this::
+
+	 class User_model extends CI_Model {      function __construct()     {         parent::__construct();     } }
+
+Your file will be this::
+
+	application/models/user_model.php
+
+Loading a Model
+===============
+
+Your models will typically be loaded and called from within your
+:doc:`controller <controllers>` functions. To load a model you will use
+the following function::
+
+	$this->load->model('Model_name');
+
+If your model is located in a sub-folder, include the relative path from
+your models folder. For example, if you have a model located at
+application/models/blog/queries.php you'll load it using::
+
+	$this->load->model('blog/queries');
+
+Once loaded, you will access your model functions using an object with
+the same name as your class::
+
+	 $this->load->model('Model_name');  $this->Model_name->function();
+
+If you would like your model assigned to a different object name you can
+specify it via the second parameter of the loading function::
+
+	 $this->load->model('Model_name', 'fubar');  $this->fubar->function();
+
+Here is an example of a controller, that loads a model, then serves a
+view::
+
+	 class Blog_controller extends CI_Controller {      function blog()     {         $this->load->model('Blog');          $data['query'] = $this->Blog->get_last_ten_entries();         $this->load->view('blog', $data);     } }
+
+Auto-loading Models
+===================
+
+If you find that you need a particular model globally throughout your
+application, you can tell CodeIgniter to auto-load it during system
+initialization. This is done by opening the
+application/config/autoload.php file and adding the model to the
+autoload array.
+
+Connecting to your Database
+===========================
+
+When a model is loaded it does **NOT** connect automatically to your
+database. The following options for connecting are available to you:
+
+-  You can connect using the standard database methods :doc:`described
+   here <../database/connecting>`, either from within your
+   Controller class or your Model class.
+-  You can tell the model loading function to auto-connect by passing
+   TRUE (boolean) via the third parameter, and connectivity settings, as
+   defined in your database config file will be used:
+   ::
+
+	$this->load->model('Model_name', '', TRUE);
+
+-  You can manually pass database connectivity settings via the third
+   parameter:
+   ::
+
+	$config['hostname'] = "localhost";         $config['username'] = "myusername";         $config['password'] = "mypassword";         $config['database'] = "mydatabase";         $config['dbdriver'] = "mysql";         $config['dbprefix'] = "";         $config['pconnect'] = FALSE;         $config['db_debug'] = TRUE;                  $this->load->model('Model_name', '', $config);

+##########################
+Profiling Your Application
+##########################
+
+The Profiler Class will display benchmark results, queries you have run,
+and $_POST data at the bottom of your pages. This information can be
+useful during development in order to help with debugging and
+optimization.
+
+Initializing the Class
+======================
+
+.. important:: This class does NOT need to be initialized. It is loaded
+	automatically by the :doc:`Output Class <../libraries/output>` if
+	profiling is enabled as shown below.
+
+Enabling the Profiler
+=====================
+
+To enable the profiler place the following function anywhere within your
+:doc:`Controller <controllers>` functions::
+
+	$this->output->enable_profiler(TRUE);
+
+When enabled a report will be generated and inserted at the bottom of
+your pages.
+
+To disable the profiler you will use::
+
+	$this->output->enable_profiler(FALSE);
+
+Setting Benchmark Points
+========================
+
+In order for the Profiler to compile and display your benchmark data you
+must name your mark points using specific syntax.
+
+Please read the information on setting Benchmark points in :doc:`Benchmark
+Class <../libraries/benchmark>` page.
+
+Enabling and Disabling Profiler Sections
+========================================
+
+Each section of Profiler data can be enabled or disabled by setting a
+corresponding config variable to TRUE or FALSE. This can be done one of
+two ways. First, you can set application wide defaults with the
+application/config/profiler.php config file.
+
+::
+
+	$config['config']          = FALSE;     $config['queries']         = FALSE;
+
+In your controllers, you can override the defaults and config file
+values by calling the set_profiler_sections() method of the :doc:`Output
+class <../libraries/output>`::
+
+	$sections = array(         'config'  => TRUE,         'queries' => TRUE         );          $this->output->set_profiler_sections($sections);
+
+Available sections and the array key used to access them are described
+in the table below.
+

+###########
+URI Routing
+###########
+
+Typically there is a one-to-one relationship between a URL string and
+its corresponding controller class/method. The segments in a URI
+normally follow this pattern::
+
+	example.com/class/function/id/
+
+In some instances, however, you may want to remap this relationship so
+that a different class/function can be called instead of the one
+corresponding to the URL.
+
+For example, lets say you want your URLs to have this prototype:
+
+example.com/product/1/
+example.com/product/2/
+example.com/product/3/
+example.com/product/4/
+
+Normally the second segment of the URL is reserved for the function
+name, but in the example above it instead has a product ID. To overcome
+this, CodeIgniter allows you to remap the URI handler.
+
+Setting your own routing rules
+==============================
+
+Routing rules are defined in your application/config/routes.php file. In
+it you'll see an array called $route that permits you to specify your
+own routing criteria. Routes can either be specified using wildcards or
+Regular Expressions
+
+Wildcards
+=========
+
+A typical wildcard route might look something like this::
+
+	$route['product/:num'] = "catalog/product_lookup";
+
+In a route, the array key contains the URI to be matched, while the
+array value contains the destination it should be re-routed to. In the
+above example, if the literal word "product" is found in the first
+segment of the URL, and a number is found in the second segment, the
+"catalog" class and the "product_lookup" method are instead used.
+
+You can match literal values or you can use two wildcard types:
+
+**(:num)** will match a segment containing only numbers.
+ **(:any)** will match a segment containing any character.
+
+.. note:: Routes will run in the order they are defined. Higher routes
+	will always take precedence over lower ones.
+
+Examples
+========
+
+Here are a few routing examples::
+
+	$route['journals'] = "blogs";
+
+A URL containing the word "journals" in the first segment will be
+remapped to the "blogs" class.
+
+::
+
+	$route['blog/joe'] = "blogs/users/34";
+
+A URL containing the segments blog/joe will be remapped to the "blogs"
+class and the "users" method. The ID will be set to "34".
+
+::
+
+	$route['product/(:any)'] = "catalog/product_lookup";
+
+A URL with "product" as the first segment, and anything in the second
+will be remapped to the "catalog" class and the "product_lookup"
+method.
+
+::
+
+	$route['product/(:num)'] = "catalog/product_lookup_by_id/$1";
+
+A URL with "product" as the first segment, and a number in the second
+will be remapped to the "catalog" class and the
+"product_lookup_by_id" method passing in the match as a variable to
+the function.
+
+.. important:: Do not use leading/trailing slashes.
+
+Regular Expressions
+===================
+
+If you prefer you can use regular expressions to define your routing
+rules. Any valid regular expression is allowed, as are back-references.
+
+.. note:: If you use back-references you must use the dollar syntax
+	rather than the double backslash syntax.
+
+A typical RegEx route might look something like this::
+
+	$route['products/([a-z]+)/(\d+)'] = "$1/id_$2";
+
+In the above example, a URI similar to products/shirts/123 would instead
+call the shirts controller class and the id_123 function.
+
+You can also mix and match wildcards with regular expressions.
+
+Reserved Routes
+===============
+
+There are two reserved routes::
+
+	$route['default_controller'] = 'welcome';
+
+This route indicates which controller class should be loaded if the URI
+contains no data, which will be the case when people load your root URL.
+In the above example, the "welcome" class would be loaded. You are
+encouraged to always have a default route otherwise a 404 page will
+appear by default.
+
+::
+
+	$route['404_override'] = '';
+
+This route indicates which controller class should be loaded if the
+requested controller is not found. It will override the default 404
+error page. It won't affect to the show_404() function, which will
+continue loading the default error_404.php file at
+application/errors/error_404.php.
+
+.. important:: The reserved routes must come before any wildcard or
+	regular expression routes.

+########
+Security
+########
+
+This page describes some "best practices" regarding web security, and
+details CodeIgniter's internal security features.
+
+URI Security
+============
+
+CodeIgniter is fairly restrictive regarding which characters it allows
+in your URI strings in order to help minimize the possibility that
+malicious data can be passed to your application. URIs may only contain
+the following:
+
+-  Alpha-numeric text
+-  Tilde: ~
+-  Period: .
+-  Colon: :
+-  Underscore: \_
+-  Dash: -
+
+Register_globals
+=================
+
+During system initialization all global variables are unset, except
+those found in the $_GET, $_POST, and $_COOKIE arrays. The unsetting
+routine is effectively the same as register_globals = off.
+
+error_reporting
+================
+
+In production environments, it is typically desirable to disable PHP's
+error reporting by setting the internal error_reporting flag to a value
+of 0. This disables native PHP errors from being rendered as output,
+which may potentially contain sensitive information.
+
+Setting CodeIgniter's ENVIRONMENT constant in index.php to a value of
+'production' will turn off these errors. In development mode, it is
+recommended that a value of 'development' is used. More information
+about differentiating between environments can be found on the :doc:`Handling
+Environments <environments>` page.
+
+magic_quotes_runtime
+======================
+
+The magic_quotes_runtime directive is turned off during system
+initialization so that you don't have to remove slashes when retrieving
+data from your database.
+
+**************
+Best Practices
+**************
+
+Before accepting any data into your application, whether it be POST data
+from a form submission, COOKIE data, URI data, XML-RPC data, or even
+data from the SERVER array, you are encouraged to practice this three
+step approach:
+
+#. Filter the data as if it were tainted.
+#. Validate the data to ensure it conforms to the correct type, length,
+   size, etc. (sometimes this step can replace step one)
+#. Escape the data before submitting it into your database.
+
+CodeIgniter provides the following functions to assist in this process:
+
+XSS Filtering
+=============
+
+CodeIgniter comes with a Cross Site Scripting filter. This filter
+looks for commonly used techniques to embed malicious Javascript into
+your data, or other types of code that attempt to hijack cookies or
+do other malicious things. The XSS Filter is described
+:doc:`here <../libraries/security>`.
+
+Validate the data
+=================
+
+CodeIgniter has a :doc:`Form Validation
+Class <../libraries/form_validation>` that assists you in
+validating, filtering, and prepping your data.
+
+Escape all data before database insertion
+=========================================
+
+Never insert information into your database without escaping it.
+Please see the section that discusses
+:doc:`queries <../database/queries>` for more information.
+

+########################
+General Style and Syntax
+########################
+
+The following page describes the use of coding rules adhered to when
+developing CodeIgniter.
+
+.. contents:: Table of Contents
+
+File Format
+===========
+
+Files should be saved with Unicode (UTF-8) encoding. The BOM should
+*not* be used. Unlike UTF-16 and UTF-32, there's no byte order to
+indicate in a UTF-8 encoded file, and the BOM can have a negative side
+effect in PHP of sending output, preventing the application from being
+able to set its own headers. Unix line endings should be used (LF).
+
+Here is how to apply these settings in some of the more common text
+editors. Instructions for your text editor may vary; check your text
+editor's documentation.
+
+TextMate
+''''''''
+
+#. Open the Application Preferences
+#. Click Advanced, and then the "Saving" tab
+#. In "File Encoding", select "UTF-8 (recommended)"
+#. In "Line Endings", select "LF (recommended)"
+#. *Optional:* Check "Use for existing files as well" if you wish to
+   modify the line endings of files you open to your new preference.
+
+BBEdit
+''''''
+
+#. Open the Application Preferences
+#. Select "Text Encodings" on the left.
+#. In "Default text encoding for new documents", select "Unicode (UTF-8,
+   no BOM)"
+#. *Optional:* In "If file's encoding can't be guessed, use", select
+   "Unicode (UTF-8, no BOM)"
+#. Select "Text Files" on the left.
+#. In "Default line breaks", select "Mac OS X and Unix (LF)"
+
+PHP Closing Tag
+===============
+
+The PHP closing tag on a PHP document **?>** is optional to the PHP
+parser. However, if used, any whitespace following the closing tag,
+whether introduced by the developer, user, or an FTP application, can
+cause unwanted output, PHP errors, or if the latter are suppressed,
+blank pages. For this reason, all PHP files should **OMIT** the closing
+PHP tag, and instead use a comment block to mark the end of file and
+it's location relative to the application root. This allows you to still
+identify a file as being complete and not truncated.
+
+::
+
+	INCORRECT: <?php  echo "Here's my code!";  ?>  CORRECT: <?php  echo "Here's my code!";  /* End of file myfile.php */ /* Location: ./system/modules/mymodule/myfile.php */
+
+Class and Method Naming
+=======================
+
+Class names should always start with an uppercase letter. Multiple words
+should be separated with an underscore, and not CamelCased. All other
+class methods should be entirely lowercased and named to clearly
+indicate their function, preferably including a verb. Try to avoid
+overly long and verbose names.
+
+::
+
+	INCORRECT: class superclass class SuperClass  CORRECT: class Super_class
+
+::
+
+	class Super_class {      function __construct()     {      } }
+
+Examples of improper and proper method naming::
+
+	INCORRECT: function fileproperties()       // not descriptive and needs underscore separator function fileProperties()       // not descriptive and uses CamelCase function getfileproperties()        // Better!  But still missing underscore separator function getFileProperties()        // uses CamelCase function get_the_file_properties_from_the_file()    // wordy  CORRECT: function get_file_properties()  // descriptive, underscore separator, and all lowercase letters
+
+Variable Names
+==============
+
+The guidelines for variable naming is very similar to that used for
+class methods. Namely, variables should contain only lowercase letters,
+use underscore separators, and be reasonably named to indicate their
+purpose and contents. Very short, non-word variables should only be used
+as iterators in for() loops.
+
+::
+
+	INCORRECT: $j = 'foo';       // single letter variables should only be used in for() loops $Str            // contains uppercase letters $bufferedText       // uses CamelCasing, and could be shortened without losing semantic meaning $groupid        // multiple words, needs underscore separator $name_of_last_city_used // too long  CORRECT: for ($j = 0; $j < 10; $j++) $str $buffer $group_id $last_city
+
+Commenting
+==========
+
+In general, code should be commented prolifically. It not only helps
+describe the flow and intent of the code for less experienced
+programmers, but can prove invaluable when returning to your own code
+months down the line. There is not a required format for comments, but
+the following are recommended.
+
+`DocBlock <http://manual.phpdoc.org/HTMLSmartyConverter/HandS/phpDocumentor/tutorial_phpDocumentor.howto.pkg.html#basics.docblock>`_
+style comments preceding class and method declarations so they can be
+picked up by IDEs::
+
+	/**  * Super Class  *  * @package Package Name  * @subpackage  Subpackage  * @category    Category  * @author  Author Name  * @link    http://example.com  */ class Super_class {
+
+::
+
+	/**  * Encodes string for use in XML  *  * @access  public  * @param   string  * @return  string  */ function xml_encode($str)
+
+Use single line comments within code, leaving a blank line between large
+comment blocks and code.
+
+::
+
+	// break up the string by newlines $parts = explode("\n", $str);  // A longer comment that needs to give greater detail on what is // occurring and why can use multiple single-line comments.  Try to // keep the width reasonable, around 70 characters is the easiest to // read.  Don't hesitate to link to permanent external resources // that may provide greater detail: // // http://example.com/information_about_something/in_particular/  $parts = $this->foo($parts);
+
+Constants
+=========
+
+Constants follow the same guidelines as do variables, except constants
+should always be fully uppercase. *Always use CodeIgniter constants when
+appropriate, i.e. SLASH, LD, RD, PATH_CACHE, etc.*
+
+::
+
+	INCORRECT: myConstant  // missing underscore separator and not fully uppercase N       // no single-letter constants S_C_VER     // not descriptive $str = str_replace('{foo}', 'bar', $str);   // should use LD and RD constants  CORRECT: MY_CONSTANT NEWLINE SUPER_CLASS_VERSION $str = str_replace(LD.'foo'.RD, 'bar', $str);
+
+TRUE, FALSE, and NULL
+=====================
+
+**TRUE**, **FALSE**, and **NULL** keywords should always be fully
+uppercase.
+
+::
+
+	INCORRECT: if ($foo == true) $bar = false; function foo($bar = null)  CORRECT: if ($foo == TRUE) $bar = FALSE; function foo($bar = NULL)
+
+Logical Operators
+=================
+
+Use of **\|\|** is discouraged as its clarity on some output devices is
+low (looking like the number 11 for instance). **&&** is preferred over
+**AND** but either are acceptable, and a space should always precede and
+follow **!**.
+
+::
+
+	INCORRECT: if ($foo || $bar) if ($foo AND $bar)  // okay but not recommended for common syntax highlighting applications if (!$foo) if (! is_array($foo))  CORRECT: if ($foo OR $bar) if ($foo && $bar) // recommended if ( ! $foo) if ( ! is_array($foo))
+
+Comparing Return Values and Typecasting
+=======================================
+
+Some PHP functions return FALSE on failure, but may also have a valid
+return value of "" or 0, which would evaluate to FALSE in loose
+comparisons. Be explicit by comparing the variable type when using these
+return values in conditionals to ensure the return value is indeed what
+you expect, and not a value that has an equivalent loose-type
+evaluation.
+
+Use the same stringency in returning and checking your own variables.
+Use **===** and **!==** as necessary.
+::
+
+	INCORRECT: // If 'foo' is at the beginning of the string, strpos will return a 0, // resulting in this conditional evaluating as TRUE if (strpos($str, 'foo') == FALSE)  CORRECT: if (strpos($str, 'foo') === FALSE)
+
+::
+
+	INCORRECT: function build_string($str = "") {     if ($str == "") // uh-oh!  What if FALSE or the integer 0 is passed as an argument?     {      } }  CORRECT: function build_string($str = "") {     if ($str === "")     {      } }
+
+
+See also information regarding
+`typecasting <http://us3.php.net/manual/en/language.types.type-juggling.php#language.types.typecasting>`_,
+which can be quite useful. Typecasting has a slightly different effect
+which may be desirable. When casting a variable as a string, for
+instance, NULL and boolean FALSE variables become empty strings, 0 (and
+other numbers) become strings of digits, and boolean TRUE becomes "1"::
+
+	$str = (string) $str; // cast $str as a string
+
+Debugging Code
+==============
+
+No debugging code can be left in place for submitted add-ons unless it
+is commented out, i.e. no var_dump(), print_r(), die(), and exit()
+calls that were used while creating the add-on, unless they are
+commented out.
+
+::
+
+	// print_r($foo);
+
+Whitespace in Files
+===================
+
+No whitespace can precede the opening PHP tag or follow the closing PHP
+tag. Output is buffered, so whitespace in your files can cause output to
+begin before CodeIgniter outputs its content, leading to errors and an
+inability for CodeIgniter to send proper headers. In the examples below,
+select the text with your mouse to reveal the incorrect whitespace.
+
+**INCORRECT**::
+
+	 <?php     // ...there is whitespace and a linebreak above the opening PHP tag     // as well as whitespace after the closing PHP tag ?>
+
+**CORRECT**::
+
+	<?php     // this sample has no whitespace before or after the opening and closing PHP tags ?>
+
+Compatibility
+=============
+
+Unless specifically mentioned in your add-on's documentation, all code
+must be compatible with PHP version 5.1+. Additionally, do not use PHP
+functions that require non-default libraries to be installed unless your
+code contains an alternative method when the function is not available,
+or you implicitly document that your add-on requires said PHP libraries.
+
+Class and File Names using Common Words
+=======================================
+
+When your class or filename is a common word, or might quite likely be
+identically named in another PHP script, provide a unique prefix to help
+prevent collision. Always realize that your end users may be running
+other add-ons or third party PHP scripts. Choose a prefix that is unique
+to your identity as a developer or company.
+
+::
+
+	INCORRECT: class Email     pi.email.php class Xml       ext.xml.php class Import        mod.import.php  CORRECT: class Pre_email     pi.pre_email.php class Pre_xml       ext.pre_xml.php class Pre_import    mod.pre_import.php
+
+Database Table Names
+====================
+
+Any tables that your add-on might use must use the 'exp\_' prefix,
+followed by a prefix uniquely identifying you as the developer or
+company, and then a short descriptive table name. You do not need to be
+concerned about the database prefix being used on the user's
+installation, as CodeIgniter's database class will automatically convert
+'exp\_' to what is actually being used.
+
+::
+
+	INCORRECT: email_addresses     // missing both prefixes pre_email_addresses // missing exp_ prefix exp_email_addresses // missing unique prefix  CORRECT: exp_pre_email_addresses
+
+**NOTE:** Be mindful that MySQL has a limit of 64 characters for table
+names. This should not be an issue as table names that would exceed this
+would likely have unreasonable names. For instance, the following table
+name exceeds this limitation by one character. Silly, no?
+**exp_pre_email_addresses_of_registered_users_in_seattle_washington**
+One File per Class
+==================
+
+Use separate files for each class your add-on uses, unless the classes
+are *closely related*. An example of CodeIgniter files that contains
+multiple classes is the Database class file, which contains both the DB
+class and the DB_Cache class, and the Magpie plugin, which contains
+both the Magpie and Snoopy classes.
+
+Whitespace
+==========
+
+Use tabs for whitespace in your code, not spaces. This may seem like a
+small thing, but using tabs instead of whitespace allows the developer
+looking at your code to have indentation at levels that they prefer and
+customize in whatever application they use. And as a side benefit, it
+results in (slightly) more compact files, storing one tab character
+versus, say, four space characters.
+
+Line Breaks
+===========
+
+Files must be saved with Unix line breaks. This is more of an issue for
+developers who work in Windows, but in any case ensure that your text
+editor is setup to save files with Unix line breaks.
+
+Code Indenting
+==============
+
+Use Allman style indenting. With the exception of Class declarations,
+braces are always placed on a line by themselves, and indented at the
+same level as the control statement that "owns" them.
+
+::
+
+	INCORRECT: function foo($bar) {     // ... }  foreach ($arr as $key => $val) {     // ... }  if ($foo == $bar) {     // ... } else {     // ... }  for ($i = 0; $i < 10; $i++)     {     for ($j = 0; $j < 10; $j++)         {         // ...         }     }  CORRECT: function foo($bar) {     // ... }  foreach ($arr as $key => $val) {     // ... }  if ($foo == $bar) {     // ... } else {     // ... }  for ($i = 0; $i < 10; $i++) {     for ($j = 0; $j < 10; $j++)     {         // ...     } }
+
+Bracket and Parenthetic Spacing
+===============================
+
+In general, parenthesis and brackets should not use any additional
+spaces. The exception is that a space should always follow PHP control
+structures that accept arguments with parenthesis (declare, do-while,
+elseif, for, foreach, if, switch, while), to help distinguish them from
+functions and increase readability.
+
+::
+
+	INCORRECT: $arr[ $foo ] = 'foo';  CORRECT: $arr[$foo] = 'foo'; // no spaces around array keys   INCORRECT: function foo ( $bar ) {  }  CORRECT: function foo($bar) // no spaces around parenthesis in function declarations {  }   INCORRECT: foreach( $query->result() as $row )  CORRECT: foreach ($query->result() as $row) // single space following PHP control structures, but not in interior parenthesis
+
+Localized Text
+==============
+
+Any text that is output in the control panel should use language
+variables in your lang file to allow localization.
+
+::
+
+	INCORRECT: return "Invalid Selection";  CORRECT: return $this->lang->line('invalid_selection');
+
+Private Methods and Variables
+=============================
+
+Methods and variables that are only accessed internally by your class,
+such as utility and helper functions that your public methods use for
+code abstraction, should be prefixed with an underscore.
+
+::
+
+	convert_text()        // public method _convert_text()     // private method
+
+PHP Errors
+==========
+
+Code must run error free and not rely on warnings and notices to be
+hidden to meet this requirement. For instance, never access a variable
+that you did not set yourself (such as $_POST array keys) without first
+checking to see that it isset().
+
+Make sure that while developing your add-on, error reporting is enabled
+for ALL users, and that display_errors is enabled in the PHP
+environment. You can check this setting with::
+
+	if (ini_get('display_errors') == 1) {     exit "Enabled"; }
+
+On some servers where display_errors is disabled, and you do not have
+the ability to change this in the php.ini, you can often enable it with::
+
+	ini_set('display_errors', 1);
+
+**NOTE:** Setting the
+`display_errors <http://us.php.net/manual/en/ref.errorfunc.php#ini.display-errors>`_
+setting with ini_set() at runtime is not identical to having it enabled
+in the PHP environment. Namely, it will not have any effect if the
+script has fatal errors
+
+Short Open Tags
+===============
+
+Always use full PHP opening tags, in case a server does not have
+short_open_tag enabled.
+
+::
+
+	INCORRECT: <? echo $foo; ?>  <?=$foo?>  CORRECT: <?php echo $foo; ?>
+
+One Statement Per Line
+======================
+
+Never combine statements on one line.
+
+::
+
+	INCORRECT: $foo = 'this'; $bar = 'that'; $bat = str_replace($foo, $bar, $bag);  CORRECT: $foo = 'this'; $bar = 'that'; $bat = str_replace($foo, $bar, $bag);
+
+Strings
+=======
+
+Always use single quoted strings unless you need variables parsed, and
+in cases where you do need variables parsed, use braces to prevent
+greedy token parsing. You may also use double-quoted strings if the
+string contains single quotes, so you do not have to use escape
+characters.
+
+::
+
+	INCORRECT: "My String"                 // no variable parsing, so no use for double quotes "My string $foo"                // needs braces 'SELECT foo FROM bar WHERE baz = \'bag\''   // ugly  CORRECT: 'My String' "My string {$foo}" "SELECT foo FROM bar WHERE baz = 'bag'"
+
+SQL Queries
+===========
+
+MySQL keywords are always capitalized: SELECT, INSERT, UPDATE, WHERE,
+AS, JOIN, ON, IN, etc.
+
+Break up long queries into multiple lines for legibility, preferably
+breaking for each clause.
+
+::
+
+	INCORRECT: // keywords are lowercase and query is too long for // a single line (... indicates continuation of line) $query = $this->db->query("select foo, bar, baz, foofoo, foobar as raboof, foobaz from exp_pre_email_addresses ...where foo != 'oof' and baz != 'zab' order by foobaz limit 5, 100");  CORRECT: $query = $this->db->query("SELECT foo, bar, baz, foofoo, foobar AS raboof, foobaz                 FROM exp_pre_email_addresses                 WHERE foo != 'oof'                 AND baz != 'zab'                 ORDER BY foobaz                 LIMIT 5, 100");
+
+Default Function Arguments
+==========================
+
+Whenever appropriate, provide function argument defaults, which helps
+prevent PHP errors with mistaken calls and provides common fallback
+values which can save a few lines of code. Example::
+
+	function foo($bar = '', $baz = FALSE)
+

+################
+CodeIgniter URLs
+################
+
+By default, URLs in CodeIgniter are designed to be search-engine and
+human friendly. Rather than using the standard "query string" approach
+to URLs that is synonymous with dynamic systems, CodeIgniter uses a
+**segment-based** approach::
+
+	example.com/news/article/my_article
+
+.. note:: Query string URLs can be optionally enabled, as described
+	below.
+
+URI Segments
+============
+
+The segments in the URL, in following with the Model-View-Controller
+approach, usually represent::
+
+	example.com/class/function/ID
+
+
+#. The first segment represents the controller **class** that should be
+   invoked.
+#. The second segment represents the class **function**, or method, that
+   should be called.
+#. The third, and any additional segments, represent the ID and any
+   variables that will be passed to the controller.
+
+The :doc::doc:`URI Class <../libraries/uri>` and the `URL
+Helper <../helpers/url_helper>` contain functions that make it
+easy to work with your URI data. In addition, your URLs can be remapped
+using the :doc:`URI Routing <routing>` feature for more flexibility.
+
+Removing the index.php file
+===========================
+
+By default, the **index.php** file will be included in your URLs::
+
+	example.com/index.php/news/article/my_article
+
+You can easily remove this file by using a .htaccess file with some
+simple rules. Here is an example of such a file, using the "negative"
+method in which everything is redirected except the specified items::
+
+	RewriteEngine on RewriteCond $1 !^(index\.php|images|robots\.txt) RewriteRule ^(.*)$ /index.php/$1 [L]
+
+In the above example, any HTTP request other than those for index.php,
+images, and robots.txt is treated as a request for your index.php file.
+
+Adding a URL Suffix
+===================
+
+In your config/config.php file you can specify a suffix that will be
+added to all URLs generated by CodeIgniter. For example, if a URL is
+this::
+
+	example.com/index.php/products/view/shoes
+
+You can optionally add a suffix, like .html, making the page appear to
+be of a certain type::
+
+	example.com/index.php/products/view/shoes.html
+
+Enabling Query Strings
+======================
+
+In some cases you might prefer to use query strings URLs::
+
+	index.php?c=products&m=view&id=345
+
+CodeIgniter optionally supports this capability, which can be enabled in
+your application/config.php file. If you open your config file you'll
+see these items::
+
+	$config['enable_query_strings'] = FALSE; $config['controller_trigger'] = 'c'; $config['function_trigger'] = 'm';
+
+If you change "enable_query_strings" to TRUE this feature will become
+active. Your controllers and functions will then be accessible using the
+"trigger" words you've set to invoke your controllers and methods::
+
+	index.php?c=controller&m=method
+
+**Please note:** If you are using query strings you will have to build
+your own URLs, rather than utilizing the URL helpers (and other helpers

+#####
+Views
+#####
+
+A view is simply a web page, or a page fragment, like a header, footer,
+sidebar, etc. In fact, views can flexibly be embedded within other views
+(within other views, etc., etc.) if you need this type of hierarchy.
+
+Views are never called directly, they must be loaded by a
+:doc:`controller <controllers>`. Remember that in an MVC framework, the
+Controller acts as the traffic cop, so it is responsible for fetching a
+particular view. If you have not read the
+:doc:`Controllers <controllers>` page you should do so before
+continuing.
+
+Using the example controller you created in the
+:doc:`controller <controllers>` page, let's add a view to it.
+
+Creating a View
+===============
+
+Using your text editor, create a file called blogview.php, and put this
+in it:
+
+<html> <head> <title>My Blog</title> </head> <body> <h1>Welcome to my
+Blog!</h1> </body> </html>
+Then save the file in your application/views/ folder.
+
+Loading a View
+==============
+
+To load a particular view file you will use the following function::
+
+	$this->load->view('name');
+
+Where name is the name of your view file. Note: The .php file extension
+does not need to be specified unless you use something other than .php.
+
+Now, open the controller file you made earlier called blog.php, and
+replace the echo statement with the view loading function:
+
+<?php class Blog extends CI_Controller { function index() {
+$this->load->view('blogview'); } } ?>
+If you visit your site using the URL you did earlier you should see your
+new view. The URL was similar to this::
+
+	example.com/index.php/blog/
+
+Loading multiple views
+======================
+
+CodeIgniter will intelligently handle multiple calls to
+$this->load->view from within a controller. If more than one call
+happens they will be appended together. For example, you may wish to
+have a header view, a menu view, a content view, and a footer view. That
+might look something like this::
+
+	<?php  class Page extends CI_Controller {      function index()    {       $data['page_title'] =  'Your title';       $this->load->view('header');       $this->load->view('menu');       $this->load->view('content', $data);       $this->load->view('footer');    }  }     ?>
+
+
+In the example above, we are using "dynamically added data", which you
+will see below.
+
+Storing Views within Sub-folders
+================================
+
+Your view files can also be stored within sub-folders if you prefer that
+type of organization. When doing so you will need to include the folder
+name loading the view. Example::
+
+	$this->load->view('folder_name/file_name');
+
+Adding Dynamic Data to the View
+===============================
+
+Data is passed from the controller to the view by way of an **array** or
+an **object** in the second parameter of the view loading function. Here
+is an example using an array::
+
+	$data = array(                'title' => 'My Title',                'heading' => 'My Heading',                'message' => 'My Message'           );  $this->load->view('blogview', $data);
+
+And here's an example using an object::
+
+	$data = new Someclass(); $this->load->view('blogview', $data);
+
+Note: If you use an object, the class variables will be turned into
+array elements.
+
+Let's try it with your controller file. Open it add this code:
+
+<?php class Blog extends CI_Controller { function index() {
+$data['title'] = "My Real Title"; $data['heading'] = "My Real Heading";
+$this->load->view('blogview', $data); } } ?>
+Now open your view file and change the text to variables that correspond
+to the array keys in your data:
+
+<html> <head> <title><?php echo $title;?></title> </head> <body>
+<h1><?php echo $heading;?></h1> </body> </html>
+Then load the page at the URL you've been using and you should see the
+variables replaced.
+
+Creating Loops
+==============
+
+The data array you pass to your view files is not limited to simple
+variables. You can pass multi dimensional arrays, which can be looped to
+generate multiple rows. For example, if you pull data from your database
+it will typically be in the form of a multi-dimensional array.
+
+Here's a simple example. Add this to your controller:
+
+<?php class Blog extends CI_Controller { function index() {
+$data['todo_list'] = array('Clean House', 'Call Mom', 'Run Errands');
+$data['title'] = "My Real Title"; $data['heading'] = "My Real Heading";
+$this->load->view('blogview', $data); } } ?>
+Now open your view file and create a loop:
+
+<html> <head> <title><?php echo $title;?></title> </head> <body>
+<h1><?php echo $heading;?></h1> <h3>My Todo List</h3> <ul> <?php foreach
+($todo_list as $item):?> <li><?php echo $item;?></li> <?php
+endforeach;?> </ul> </body> </html>
+
+.. note:: You'll notice that in the example above we are using PHP's
+	alternative syntax. If you are not familiar with it you can read about
+	it `here </general/alternative_php>`.
+
+Returning views as data
+=======================
+
+There is a third **optional** parameter lets you change the behavior of
+the function so that it returns data as a string rather than sending it
+to your browser. This can be useful if you want to process the data in
+some way. If you set the parameter to true (boolean) it will return
+data. The default behavior is false, which sends it to your browser.
+Remember to assign it to a variable if you want the data returned::
+
+	$string = $this->load->view('myfile', '', true);

+############
+Array Helper
+############
+
+The Array Helper file contains functions that assist in working with
+arrays.
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+	$this->load->helper('array');
+
+The following functions are available:
+
+element()
+=========
+
+.. php:method:: element($item, $array, $default = FALSE)
+
+	:param string 	$item: Item to fetch from the array
+	:param array 	$array: Input array
+	:param boolean	$default: What to return if the array isn't valid
+	:returns: FALSE on failure or the array item.
+
+
+Lets you fetch an item from an array. The function tests whether the
+array index is set and whether it has a value. If a value exists it is
+returned. If a value does not exist it returns FALSE, or whatever you've
+specified as the default value via the third parameter. Example
+
+::
+
+	$array = array(
+		'color'	=> 'red',
+		'shape'	=> 'round',
+		'size'	=> ''
+	);
+
+	echo element('color', $array); // returns "red" 
+	echo element('size', $array, NULL); // returns NULL 
+
+elements()
+==========
+
+Lets you fetch a number of items from an array. The function tests
+whether each of the array indices is set. If an index does not exist it
+is set to FALSE, or whatever you've specified as the default value via
+the third parameter. 
+
+.. php:method:: elements($items, $array, $default = FALSE)
+
+	:param string 	$item: Item to fetch from the array
+	:param array 	$array: Input array
+	:param boolean	$default: What to return if the array isn't valid
+	:returns: FALSE on failure or the array item.
+
+Example
+
+::
+
+	$array = array(
+		'color' => 'red',  
+		'shape' => 'round',     
+		'radius' => '10',     
+		'diameter' => '20'
+	);
+
+	$my_shape = elements(array('color', 'shape', 'height'), $array);
+
+The above will return the following array
+
+::
+
+	array(
+		'color' => 'red',     
+		'shape' => 'round',     
+		'height' => FALSE
+	);
+
+You can set the third parameter to any default value you like
+
+::
+
+	 $my_shape = elements(array('color', 'shape', 'height'), $array, NULL);
+
+The above will return the following array
+
+::
+
+	array(     
+		'color' 	=> 'red',     
+		'shape' 	=> 'round',     
+		'height'	=> NULL
+	);
+
+This is useful when sending the $_POST array to one of your Models.
+This prevents users from sending additional POST data to be entered into
+your tables
+
+::
+
+	$this->load->model('post_model');
+	$this->post_model->update(
+		elements(array('id', 'title', 'content'), $_POST)
+	);
+
+This ensures that only the id, title and content fields are sent to be
+updated.
+
+random_element()
+================
+
+Takes an array as input and returns a random element from it. Usage
+example
+
+.. php:method:: random_element($array)
+
+	:param array 	$array: Input array
+	:returns: String - Random element from the array.
+
+::
+
+	$quotes = array(
+		"I find that the harder I work, the more luck I seem to have. - Thomas Jefferson",
+		"Don't stay in bed, unless you can make money in bed. - George Burns",
+		"We didn't lose the game; we just ran out of time. - Vince Lombardi",
+		"If everything seems under control, you're not going fast enough. - Mario Andretti",
+		"Reality is merely an illusion, albeit a very persistent one. - Albert Einstein",
+		"Chance favors the prepared mind - Louis Pasteur"
+	);
+
+	echo random_element($quotes);
+

+CAPTCHA Helper
+##############
+
+The CAPTCHA Helper file contains functions that assist in creating
+CAPTCHA images.
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+	$this->load->helper('captcha');
+
+The following functions are available:
+
+create_captcha($data)
+=====================
+
+Takes an array of information to generate the CAPTCHA as input and
+creates the image to your specifications, returning an array of
+associative data about the image.
+
+.. php:method:: function create_captcha($data = '', $img_path = '', $img_url = '', $font_path = '')
+
+	:param array 	$data: array of data for the CAPTCHA
+	:param string 	$img_path: path to create the image in
+	:param string	$img_url: URL to the CAPTCHA image folder
+	:param string	$font_path: server path to font
+	:returns: array('word' => $word, 'time' => $now, 'image' => $img)
+
+
+::
+
+	[array] (
+		'image' => IMAGE TAG   
+		'time'  => TIMESTAMP (in microtime)   
+		'word'  => CAPTCHA WORD )
+
+The "image" is the actual image tag:
+
+::
+
+	<img src="http://example.com/captcha/12345.jpg" width="140" height="50" />
+
+
+The "time" is the micro timestamp used as the image name without the
+file extension. It will be a number like this: 1139612155.3422
+
+The "word" is the word that appears in the captcha image, which if not
+supplied to the function, will be a random string.
+
+Using the CAPTCHA helper
+------------------------
+
+Once loaded you can generate a captcha like this
+
+::
+
+	$vals = array(     
+		'word'       => 'Random word',     
+		'img_path'   => './captcha/',     
+		'img_url'    => 'http://example.com/captcha/',     
+		'font_path'  => './path/to/fonts/texb.ttf',     
+		'img_width'  => '150',     
+		'img_height' => 30,     
+		'expiration' => 7200     
+	);
+
+	$cap = create_captcha($vals); echo $cap['image'];
+
+
+-  The captcha function requires the GD image library.
+-  Only the img_path and img_url are required.
+-  If a "word" is not supplied, the function will generate a random
+   ASCII string. You might put together your own word library that you
+   can draw randomly from.
+-  If you do not specify a path to a TRUE TYPE font, the native ugly GD
+   font will be used.
+-  The "captcha" folder must be writable (666, or 777)
+-  The "expiration" (in seconds) signifies how long an image will remain
+   in the captcha folder before it will be deleted. The default is two
+   hours.
+
+Adding a Database
+-----------------
+
+In order for the captcha function to prevent someone from submitting,
+you will need to add the information returned from create_captcha()
+function to your database. Then, when the data from the form is
+submitted by the user you will need to verify that the data exists in
+the database and has not expired.
+
+Here is a table prototype
+
+::
+
+	CREATE TABLE captcha (  
+		captcha_id bigint(13) unsigned NOT NULL auto_increment,  
+		captcha_time int(10) unsigned NOT NULL,  
+		ip_address varchar(16) default '0' NOT NULL,  
+		word varchar(20) NOT NULL,  
+		PRIMARY KEY `captcha_id` (`captcha_id`),  
+		KEY `word` (`word`)
+	);
+
+Here is an example of usage with a database. On the page where the
+CAPTCHA will be shown you'll have something like this
+
+::
+
+	$this->load->helper('captcha');
+	$vals = array(     
+		'img_path'	=> './captcha/',     
+		'img_url'	=> 'http://example.com/captcha/'     
+	);
+
+	$cap = create_captcha($vals);
+	$data = array(     
+		'captcha_time'	=> $cap['time'],     
+		'ip_address'	=> $this->input->ip_address(),     
+		'word'		=> $cap['word']     
+	);
+
+	$query = $this->db->insert_string('captcha', $data);
+	$this->db->query($query);
+
+	echo 'Submit the word you see below:';
+	echo $cap['image']; 
+	echo '<input type="text" name="captcha" value="" />';
+
+Then, on the page that accepts the submission you'll have something like
+this
+
+::
+
+	// First, delete old captchas
+	$expiration = time() - 7200; // Two hour limit
+	$this->db->where('captcha_time < ', $expiration)
+		 ->delete('captcha');
+
+	// Then see if a captcha exists:
+	$sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND captcha_time > ?";
+	$binds = array($_POST['captcha'], $this->input->ip_address(), $expiration);
+	$query = $this->db->query($sql, $binds);
+	$row = $query->row();
+
+	if ($row->count == 0)
+	{     
+		echo "You must submit the word that appears in the image";
+	}
+

+###########
+Date Helper
+###########
+
+The Date Helper file contains functions that help you work with dates.
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+	$this->load->helper('date');
+
+The following functions are available:
+
+now()
+=====
+
+Returns the current time as a Unix timestamp, referenced either to your
+server's local time or GMT, based on the "time reference" setting in
+your config file. If you do not intend to set your master time reference
+to GMT (which you'll typically do if you run a site that lets each user
+set their own timezone settings) there is no benefit to using this
+function over PHP's time() function.
+
+.. php:method:: now()
+
+mdate()
+=======
+
+This function is identical to PHPs `date() <http://www.php.net/date>`_
+function, except that it lets you use MySQL style date codes, where each
+code letter is preceded with a percent sign: %Y %m %d etc.
+
+The benefit of doing dates this way is that you don't have to worry
+about escaping any characters that are not date codes, as you would
+normally have to do with the date() function. Example
+
+.. php:method:: mdate($datestr = '', $time = '')
+
+	:param string 	$datestr: Date String
+	:param integer 	$time: time
+	:returns: integer
+
+
+::
+
+	$datestring = "Year: %Y Month: %m Day: %d - %h:%i %a";
+	$time = time();
+	echo mdate($datestring, $time);
+
+If a timestamp is not included in the second parameter the current time
+will be used.
+
+standard_date()
+===============
+
+Lets you generate a date string in one of several standardized formats.
+Example
+
+.. php:method:: standard_date($fmt = 'DATE_RFC822', $time = '')
+
+	:param string 	$fmt: the chosen format
+	:param string 	$time: Unix timestamp
+	:returns: string
+
+::
+
+	$format = 'DATE_RFC822';
+	$time = time();
+	echo standard_date($format, $time);
+
+The first parameter must contain the format, the second parameter must
+contain the date as a Unix timestamp.
+
+Supported formats:
+

+format with this prototype
+
+.. php:method:: unix_to_human($time = '', $seconds = FALSE, $fmt = 'us')
+
+	:param integer 	$time: Unix timestamp
+	:param boolean 	$seconds: whether to show seconds
+	:param string 	$fmt: format: us or euro
+	:returns: integer
+
+Example
+
+::
+
+	YYYY-MM-DD HH:MM:SS AM/PM
+
+This can be useful if you need to display a date in a form field for
+submission.
+
+The time can be formatted with or without seconds, and it can be set to
+European or US format. If only the timestamp is submitted it will return
+the time without seconds formatted for the U.S. Examples
+
+::
+
+	$now = time();
+	echo unix_to_human($now); // U.S. time, no seconds
+	echo unix_to_human($now, TRUE, 'us'); // U.S. time with seconds
+	echo unix_to_human($now, TRUE, 'eu'); // Euro time with seconds
+
+human_to_unix()
+===============
+
+The opposite of the above function. Takes a "human" time as input and
+returns it as Unix. This function is useful if you accept "human"
+formatted dates submitted via a form. Returns FALSE (boolean) if the
+date string passed to it is not formatted as indicated above. 
+
+.. php:method:: human_to_unix($datestr = '')
+
+	:param integer 	$datestr: Date String
+	:returns: integer
+
+Example:
+
+::
+
+	$now = time();
+	$human = unix_to_human($now);
+	$unix = human_to_unix($human);
+
+nice_date()
+===========
+
+This function can take a number poorly-formed date formats and convert
+them into something useful. It also accepts well-formed dates.
+
+The function will return a Unix timestamp by default. You can,
+optionally, pass a format string (the same type as the PHP date function
+accepts) as the second parameter. 
+
+.. php:method:: nice_date($bad_date = '', $format = FALSE) 
+
+	:param integer 	$bad_date: The terribly formatted date-like string
+	:param string 	$format: Date format to return (same as php date function)
+	:returns: string
+
+Example
+
+::
+
+	$bad_time = 199605  // Should Produce: 1996-05-01
+	$better_time = nice_date($bad_time,'Y-m-d');
+	$bad_time = 9-11-2001 // Should Produce: 2001-09-11
+	$better_time = nice_date($human,'Y-m-d');
+
+timespan()
+==========
+
+Formats a unix timestamp so that is appears similar to this
+
+::
+
+	1 Year, 10 Months, 2 Weeks, 5 Days, 10 Hours, 16 Minutes
+
+The first parameter must contain a Unix timestamp. The second parameter
+must contain a timestamp that is greater that the first timestamp. If
+the second parameter empty, the current time will be used. The most
+common purpose for this function is to show how much time has elapsed
+from some point in time in the past to now. 
+
+.. php:method:: timespan($seconds = 1, $time = '')
+
+	:param integer 	$seconds: a number of seconds
+	:param string 	$time: Unix timestamp
+	:returns: string
+
+Example
+
+::
+
+	$post_date = '1079621429';
+	$now = time();
+	echo timespan($post_date, $now);
+
+.. note:: The text generated by this function is found in the following language
+	file: language/<your_lang>/date_lang.php
+
+days_in_month()
+===============
+
+Returns the number of days in a given month/year. Takes leap years into
+account. 
+
+.. php:method:: days_in_month($month = 0, $year = '')
+
+	:param integer 	$month: a numeric month
+	:param integer 	$year: a numeric year
+	:returns: integer
+
+Example
+
+::
+
+	echo days_in_month(06, 2005);
+
+If the second parameter is empty, the current year will be used.
+
+timezones()
+===========
+
+Takes a timezone reference (for a list of valid timezones, see the
+"Timezone Reference" below) and returns the number of hours offset from
+UTC.
+
+.. php:method:: timezones($tz = '')
+
+	:param string 	$tz: a numeric timezone
+	:returns: string
+
+Example
+
+::
+
+	echo timezones('UM5');
+
+
+This function is useful when used with `timezone_menu()`.
+
+timezone_menu()
+===============
+
+Generates a pull-down menu of timezones, like this one:
+
+
+.. raw:: html
+
+	<form action="#">
+		<select name="timezones">
+			<option value='UM12'>(UTC - 12:00) Enitwetok, Kwajalien</option>
+			<option value='UM11'>(UTC - 11:00) Nome, Midway Island, Samoa</option>
+			<option value='UM10'>(UTC - 10:00) Hawaii</option>
+			<option value='UM9'>(UTC - 9:00) Alaska</option>
+			<option value='UM8'>(UTC - 8:00) Pacific Time</option>
+			<option value='UM7'>(UTC - 7:00) Mountain Time</option>
+			<option value='UM6'>(UTC - 6:00) Central Time, Mexico City</option>
+			<option value='UM5'>(UTC - 5:00) Eastern Time, Bogota, Lima, Quito</option>
+			<option value='UM4'>(UTC - 4:00) Atlantic Time, Caracas, La Paz</option>
+			<option value='UM25'>(UTC - 3:30) Newfoundland</option>
+			<option value='UM3'>(UTC - 3:00) Brazil, Buenos Aires, Georgetown, Falkland Is.</option>
+			<option value='UM2'>(UTC - 2:00) Mid-Atlantic, Ascention Is., St Helena</option>
+			<option value='UM1'>(UTC - 1:00) Azores, Cape Verde Islands</option>
+			<option value='UTC' selected='selected'>(UTC) Casablanca, Dublin, Edinburgh, London, Lisbon, Monrovia</option>
+			<option value='UP1'>(UTC + 1:00) Berlin, Brussels, Copenhagen, Madrid, Paris, Rome</option>
+			<option value='UP2'>(UTC + 2:00) Kaliningrad, South Africa, Warsaw</option>
+			<option value='UP3'>(UTC + 3:00) Baghdad, Riyadh, Moscow, Nairobi</option>
+			<option value='UP25'>(UTC + 3:30) Tehran</option>
+			<option value='UP4'>(UTC + 4:00) Adu Dhabi, Baku, Muscat, Tbilisi</option>
+			<option value='UP35'>(UTC + 4:30) Kabul</option>
+			<option value='UP5'>(UTC + 5:00) Islamabad, Karachi, Tashkent</option>
+			<option value='UP45'>(UTC + 5:30) Bombay, Calcutta, Madras, New Delhi</option>
+			<option value='UP6'>(UTC + 6:00) Almaty, Colomba, Dhaka</option>
+			<option value='UP7'>(UTC + 7:00) Bangkok, Hanoi, Jakarta</option>
+			<option value='UP8'>(UTC + 8:00) Beijing, Hong Kong, Perth, Singapore, Taipei</option>
+			<option value='UP9'>(UTC + 9:00) Osaka, Sapporo, Seoul, Tokyo, Yakutsk</option>
+			<option value='UP85'>(UTC + 9:30) Adelaide, Darwin</option>
+			<option value='UP10'>(UTC + 10:00) Melbourne, Papua New Guinea, Sydney, Vladivostok</option>
+			<option value='UP11'>(UTC + 11:00) Magadan, New Caledonia, Solomon Islands</option>
+			<option value='UP12'>(UTC + 12:00) Auckland, Wellington, Fiji, Marshall Island</option>
+		</select>
+	</form>
+
+
+This menu is useful if you run a membership site in which your users are
+allowed to set their local timezone value.
+
+The first parameter lets you set the "selected" state of the menu. For
+example, to set Pacific time as the default you will do this
+
+.. php:method:: timezone_menu($default = 'UTC', $class = "", $name = 'timezones')
+
+	:param string 	$default: timezone
+	:param string	$class: classname
+	:param string	$name: menu name
+	:returns: string
+
+Example: 
+
+::
+
+	echo timezone_menu('UM8');
+
+Please see the timezone reference below to see the values of this menu.
+
+The second parameter lets you set a CSS class name for the menu.
+
+.. note:: The text contained in the menu is found in the following
+	language file: `language/<your_lang>/date_lang.php`
+
+

+Directory Helper
+################
+
+The Directory Helper file contains functions that assist in working with
+directories.
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+	$this->load->helper('directory');
+
+The following functions are available:
+
+directory_map('source directory')
+=================================
+
+This function reads the directory path specified in the first parameter
+and builds an array representation of it and all its contained files.
+
+Example
+
+::
+
+	$map = directory_map('./mydirectory/');
+
+.. note:: Paths are almost always relative to your main index.php file.
+
+
+Sub-folders contained within the directory will be mapped as well. If
+you wish to control the recursion depth, you can do so using the second
+parameter (integer). A depth of 1 will only map the top level directory
+
+::
+
+	$map = directory_map('./mydirectory/', 1);
+
+By default, hidden files will not be included in the returned array. To
+override this behavior, you may set a third parameter to true (boolean)
+
+::
+
+	$map = directory_map('./mydirectory/', FALSE, TRUE);
+
+Each folder name will be an array index, while its contained files will
+be numerically indexed. Here is an example of a typical array
+
+::
+
+	Array (    
+		[libraries] => Array    
+			(        
+				[0] => benchmark.html        
+				[1] => config.html        
+				[database] => Array
+					(              
+						[0] => active_record.html              
+						[1] => binds.html              
+						[2] => configuration.html
+						[3] => connecting.html              
+						[4] => examples.html              
+						[5] => fields.html              
+						[6] => index.html
+						[7] => queries.html
+					)

+###########
+File Helper
+###########
+
+The File Helper file contains functions that assist in working with files.
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+	$this->load->helper('file');
+
+The following functions are available:
+
+read_file('path')
+=================
+
+Returns the data contained in the file specified in the path. Example
+
+::
+
+	$string = read_file('./path/to/file.php');
+
+The path can be a relative or full server path. Returns FALSE (boolean) on failure.
+
+.. note:: The path is relative to your main site index.php file, NOT your
+	controller or view files. CodeIgniter uses a front controller so paths
+	are always relative to the main site index.
+
+If your server is running an `open_basedir` restriction this function might not work if you are trying to access a file above the calling script.
+
+write_file('path', $data)
+=========================
+
+Writes data to the file specified in the path. If the file does not exist the function will create it. Example
+
+::
+
+	$data = 'Some file data';
+	if ( ! write_file('./path/to/file.php', $data))
+	{     
+		echo 'Unable to write the file';
+	}
+	else
+	{     
+		echo 'File written!';
+	}
+
+You can optionally set the write mode via the third parameter
+
+::
+
+	write_file('./path/to/file.php', $data, 'r+');
+
+The default mode is wb. Please see the `PHP user guide <http://php.net/fopen>`_ for mode options.
+
+Note: In order for this function to write data to a file its file permissions must be set such that it is writable (666, 777, etc.). If the file does not already exist, the directory containing it must be writable.
+
+.. note:: The path is relative to your main site index.php file, NOT your
+	controller or view files. CodeIgniter uses a front controller so paths
+	are always relative to the main site index.
+
+delete_files('path')
+====================
+
+Deletes ALL files contained in the supplied path. Example
+
+::
+
+	delete_files('./path/to/directory/');
+
+If the second parameter is set to true, any directories contained within the supplied root path will be deleted as well. Example
+
+::
+
+	delete_files('./path/to/directory/', TRUE);
+
+.. note:: The files must be writable or owned by the system in order to be deleted.
+
+get_filenames('path/to/directory/')
+===================================
+
+Takes a server path as input and returns an array containing the names of all files contained within it. The file path can optionally be added to the file names by setting the second parameter to TRUE.
+
+get_dir_file_info('path/to/directory/', $top_level_only = TRUE)
+===============================================================
+
+Reads the specified directory and builds an array containing the filenames, filesize, dates, and permissions. Sub-folders contained within the specified path are only read if forced by sending the second parameter, $top_level_only to FALSE, as this can be an intensive operation.
+
+get_file_info('path/to/file', $file_information)
+================================================
+
+Given a file and path, returns the name, path, size, date modified. Second parameter allows you to explicitly declare what information you want returned; options are: `name`, `server_path`, `size`, `date`, `readable`, `writable`, `executable`, `fileperms`. Returns FALSE if the file cannot be found.
+
+.. note:: The "writable" uses the PHP function is_writable() which is known
+	to have issues on the IIS webserver. Consider using fileperms instead,
+	which returns information from PHP's fileperms() function.
+
+get_mime_by_extension('file')
+=============================
+
+Translates a file extension into a mime type based on config/mimes.php. Returns FALSE if it can't determine the type, or open the mime config file.
+
+::
+
+	$file = "somefile.png";
+	echo $file . ' is has a mime type of ' . get_mime_by_extension($file);
+
+
+.. note:: This is not an accurate way of determining file mime types, and
+	is here strictly as a convenience. It should not be used for security.
+
+symbolic_permissions($perms)
+============================
+
+Takes numeric permissions (such as is returned by `fileperms()` and returns standard symbolic notation of file permissions.
+
+::
+
+	echo symbolic_permissions(fileperms('./index.php'));  // -rw-r--r--
+
+octal_permissions($perms)
+=========================
+
+Takes numeric permissions (such as is returned by fileperms() and returns a three character octal notation of file permissions.
+
+::
+
+	echo octal_permissions(fileperms('./index.php'));  // 644
+

+Creates an opening form tag with a base URL **built from your config preferences**. It will optionally let you add form attributes and hidden input fields, and will always add the attribute accept-charset based on the charset value in your config file.
+
+The main benefit of using this tag rather than hard coding your own HTML is that it permits your site to be more portable in the event your URLs ever change.
+
+Here's a simple example
+
+::
+
+	echo form_open('email/send');
+
+The above example would create a form that points to your base URL plus the "email/send" URI segments, like this
+
+::
+
+	<form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send" />
+
+Adding Attributes
+^^^^^^^^^^^^^^^^^
+
+Attributes can be added by passing an associative array to the second
+parameter, like this
+
+::
+
+	$attributes = array('class' => 'email', 'id' => 'myform');  
+	echo form_open('email/send', $attributes);
+
+The above example would create a form similar to this
+
+::
+
+	<form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send" class="email" id="myform" />
+
+Adding Hidden Input Fields
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Hidden fields can be added by passing an associative array to the third parameter, like this
+
+::
+
+	 $hidden = array('username' => 'Joe', 'member_id' => '234');  
+	echo form_open('email/send', '', $hidden);
+
+The above example would create a form similar to this
+
+::
+
+	<form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send"> 
+		<input type="hidden" name="username" value="Joe" /> 
+		<input type="hidden" name="member_id" value="234" />
+
+form_open_multipart()
+=====================
+
+This function is absolutely identical to the `form_open()` tag above
+except that it adds a multipart attribute, which is necessary if you
+would like to use the form to upload files with.
+
+form_hidden()
+=============
+
+Lets you generate hidden input fields. You can either submit a
+name/value string to create one field
+
+::
+
+	form_hidden('username', 'johndoe');  
+	// Would produce: <input type="hidden" name="username" value="johndoe" />
+
+Or you can submit an associative array to create multiple fields
+
+::
+
+	$data = array(               
+		'name'  => 'John Doe',               
+		'email' => 'john@example.com',               
+		'url'   => 'http://example.com'             
+	);  
+	
+	echo form_hidden($data);  
+	
+	/*
+		Would produce: 
+		<input type="hidden" name="name" value="John Doe" /> 
+		<input type="hidden" name="email" value="john@example.com" /> 
+		<input type="hidden" name="url" value="http://example.com" />
+	*/
+
+form_input()
+============
+
+Lets you generate a standard text input field. You can minimally pass
+the field name and value in the first and second parameter
+
+::
+
+	echo form_input('username', 'johndoe');
+
+Or you can pass an associative array containing any data you wish your
+form to contain
+
+::
+
+	$data = array(               
+		'name'        => 'username',               
+		'id'          => 'username',               
+		'value'       => 'johndoe',               
+		'maxlength'   => '100',               
+		'size'        => '50',               
+		'style'       => 'width:50%',             
+	);  
+	
+	echo form_input($data);
+	
+	/*
+		Would produce:
+		
+		<input type="text" name="username" id="username" value="johndoe" maxlength="100" size="50" style="width:50%" />
+	*/
+
+If you would like your form to contain some additional data, like
+Javascript, you can pass it as a string in the third parameter
+
+::
+
+	$js = 'onClick="some_function()"';  
+	echo form_input('username', 'johndoe', $js);
+
+form_password()
+===============
+
+This function is identical in all respects to the `form_input()` function above except that it uses the "password" input type.
+
+form_upload()
+=============
+
+This function is identical in all respects to the `form_input()` function above except that it uses the "file" input type, allowing it to be used to upload files.
+
+form_textarea()
+===============
+
+This function is identical in all respects to the `form_input()` function above except that it generates a "textarea" type. Note: Instead of the "maxlength" and "size" attributes in the above example, you will instead specify "rows" and "cols".
+
+form_dropdown()
+===============
+
+Lets you create a standard drop-down field. The first parameter will
+contain the name of the field, the second parameter will contain an
+associative array of options, and the third parameter will contain the
+value you wish to be selected. You can also pass an array of multiple
+items through the third parameter, and CodeIgniter will create a
+multiple select for you. Example
+
+::
+
+	$options = array(                   
+		'small'  => 'Small Shirt',                   
+		'med'    => 'Medium Shirt',                   
+		'large'   => 'Large Shirt',                   
+		'xlarge' => 'Extra Large Shirt',                 
+	);  
+	
+	$shirts_on_sale = array('small', 'large');  
+	echo form_dropdown('shirts', $options, 'large');  
+	
+	/*
+		Would produce:  
+		
+		<select name="shirts"> 
+			<option value="small">Small Shirt</option> 
+			<option value="med">Medium  Shirt</option> 
+			<option value="large" selected="selected">Large Shirt</option> 
+			<option value="xlarge">Extra Large Shirt</option> 
+		</select>
+	*/
+	
+	echo form_dropdown('shirts', $options, $shirts_on_sale);
+	
+	/*
+		Would produce:  
+	
+		<select name="shirts" multiple="multiple"> 
+			<option value="small" selected="selected">Small Shirt</option> 
+			<option value="med">Medium  Shirt</option> 
+			<option value="large" selected="selected">Large Shirt</option> 	
+			<option value="xlarge">Extra Large Shirt</option> 
+		</select>
+	*/
+
+If you would like the opening <select> to contain additional data, like
+an id attribute or JavaScript, you can pass it as a string in the fourth
+parameter
+
+::
+
+	$js = 'id="shirts" onChange="some_function();"';  
+	echo form_dropdown('shirts', $options, 'large', $js);
+
+If the array passed as $options is a multidimensional array,
+`form_dropdown()` will produce an <optgroup> with the array key as the
+label.
+
+form_multiselect()
+==================
+
+Lets you create a standard multiselect field. The first parameter will
+contain the name of the field, the second parameter will contain an
+associative array of options, and the third parameter will contain the
+value or values you wish to be selected. The parameter usage is
+identical to using form_dropdown() above, except of course that the
+name of the field will need to use POST array syntax, e.g. foo[].
+
+form_fieldset()
+================
+
+Lets you generate fieldset/legend fields.
+
+::
+
+	echo form_fieldset('Address Information'); 
+	echo "<p>fieldset content here</p>\n"; 
+	echo form_fieldset_close();
+	
+	/*
+		Produces:
+			<fieldset>  
+				<legend>Address Information</legend>  
+					<p>form content here</p>  
+			</fieldset>
+	*/
+	
+Similar to other functions, you can submit an associative array in the
+second parameter if you prefer to set additional attributes.
+
+::
+
+	$attributes = array(
+		'id' => 'address_info', 
+		'class' => 'address_info'
+	);     
+	
+	echo form_fieldset('Address Information', $attributes); 
+	echo "<p>fieldset content here</p>\n"; 
+	echo form_fieldset_close();   
+	
+	/*
+		Produces: 
+		
+		<fieldset id="address_info" class="address_info">  
+			<legend>Address Information</legend>  
+			<p>form content here</p>  
+		</fieldset>
+	*/
+
+form_fieldset_close()
+=====================
+
+Produces a closing </fieldset> tag. The only advantage to using this
+function is it permits you to pass data to it which will be added below
+the tag. For example
+
+::
+
+	$string = "</div></div>";  
+	echo form_fieldset_close($string);  
+	// Would produce: </fieldset> </div></div>
+
+form_checkbox()
+===============
+
+Lets you generate a checkbox field. Simple example
+
+::
+
+	echo form_checkbox('newsletter', 'accept', TRUE);  
+	// Would produce:  <input type="checkbox" name="newsletter" value="accept" checked="checked" />
+
+The third parameter contains a boolean TRUE/FALSE to determine whether
+the box should be checked or not.
+
+Similar to the other form functions in this helper, you can also pass an
+array of attributes to the function
+
+::
+
+	$data = array(     
+		'name'        => 'newsletter',     
+		'id'          => 'newsletter',     
+		'value'       => 'accept',     
+		'checked'     => TRUE,     
+		'style'       => 'margin:10px',     
+	);  
+	
+	echo form_checkbox($data);  
+	// Would produce: <input type="checkbox" name="newsletter" id="newsletter" value="accept" checked="checked" style="margin:10px" />
+
+As with other functions, if you would like the tag to contain additional
+data, like JavaScript, you can pass it as a string in the fourth
+parameter
+
+::
+
+	$js = 'onClick="some_function()"';   
+	echo form_checkbox('newsletter', 'accept', TRUE, $js)
+
+form_radio()
+============
+
+This function is identical in all respects to the `form_checkbox()`
+function above except that it uses the "radio" input type.
+
+form_submit()
+=============
+
+Lets you generate a standard submit button. Simple example
+
+::
+
+	echo form_submit('mysubmit', 'Submit Post!');  
+	// Would produce:  <input type="submit" name="mysubmit" value="Submit Post!" />
+
+Similar to other functions, you can submit an associative array in the
+first parameter if you prefer to set your own attributes. The third
+parameter lets you add extra data to your form, like JavaScript.
+
+form_label()
+============
+
+Lets you generate a <label>. Simple example
+
+::
+
+	echo form_label('What is your Name', 'username');  
+	// Would produce:  <label for="username">What is your Name</label>
+
+Similar to other functions, you can submit an associative array in the
+third parameter if you prefer to set additional attributes.
+
+::
+
+	$attributes = array(     
+		'class' => 'mycustomclass',     
+		'style' => 'color: #000;'
+	);     
+	
+	echo form_label('What is your Name', 'username', $attributes);          
+	// Would produce:  <label for="username" class="mycustomclass" style="color: #000;">What is your Name</label>
+
+
+form_reset()
+============
+
+Lets you generate a standard reset button. Use is identical to
+`form_submit()`.
+
+form_button()
+=============
+
+Lets you generate a standard button element. You can minimally pass the
+button name and content in the first and second parameter
+
+::
+
+	 echo form_button('name','content');  
+	// Would produce <button name="name" type="button">Content</button>
+
+Or you can pass an associative array containing any data you wish your
+form to contain:
+
+::
+
+	$data = array(     
+		'name' 		=> 'button',     
+		'id' 		=> 'button',     
+		'value' 	=> 'true',     
+		'type' 		=> 'reset',     
+		'content' 	=> 'Reset' 
+	);  
+	
+	echo form_button($data);  
+	// Would produce: <button name="button" id="button" value="true" type="reset">Reset</button>
+
+If you would like your form to contain some additional data, like
+JavaScript, you can pass it as a string in the third parameter:
+
+::
+
+	 $js = 'onClick="some_function()"'; 
+	echo form_button('mybutton', 'Click Me', $js);
+
+form_close()
+============
+
+Produces a closing </form> tag. The only advantage to using this
+function is it permits you to pass data to it which will be added below
+the tag. For example
+
+::
+
+	$string = "</div></div>";  
+	echo form_close($string);  
+	// Would produce:  </form> </div></div>
+
+form_prep()
+===========
+
+Allows you to safely use HTML and characters such as quotes within form
+elements without breaking out of the form. Consider this example
+
+::
+
+	$string = 'Here is a string containing "quoted" text.';  
+	<input type="text" name="myform" value="$string" />
+
+Since the above string contains a set of quotes it will cause the form
+to break. The `form_prep()` function converts HTML so that it can be used
+safely
+
+::
+
+	<input type="text" name="myform" value="<?php echo form_prep($string); ?>" />
+
+.. note:: If you use any of the form helper functions listed in this page the form
+	values will be prepped automatically, so there is no need to call this
+	function. Use it only if you are creating your own form elements.
+
+set_value()
+===========
+
+Permits you to set the value of an input form or textarea. You must
+supply the field name via the first parameter of the function. The
+second (optional) parameter allows you to set a default value for the
+form. Example
+
+::
+
+	<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" />
+
+The above form will show "0" when loaded for the first time.
+
+set_select()
+============
+
+If you use a <select> menu, this function permits you to display the
+menu item that was selected. The first parameter must contain the name
+of the select menu, the second parameter must contain the value of each
+item, and the third (optional) parameter lets you set an item as the
+default (use boolean TRUE/FALSE).
+
+Example
+
+::
+
+	<select name="myselect">
+		<option value="one" <?php echo  set_select('myselect', 'one', TRUE); ?> >One</option> 
+		<option value="two" <?php echo  set_select('myselect', 'two'); ?> >Two</option> 
+		<option value="three" <?php echo  set_select('myselect', 'three'); ?> >Three</option> 
+	</select>
+
+set_checkbox()
+==============
+
+Permits you to display a checkbox in the state it was submitted. The
+first parameter must contain the name of the checkbox, the second
+parameter must contain its value, and the third (optional) parameter
+lets you set an item as the default (use boolean TRUE/FALSE). Example
+
+::
+
+	<input type="checkbox" name="mycheck" value="1" <?php echo set_checkbox('mycheck', '1'); ?> /> 
+	<input type="checkbox" name="mycheck" value="2" <?php echo set_checkbox('mycheck', '2'); ?> />
+
+set_radio()
+===========
+
+Permits you to display radio buttons in the state they were submitted.
+This function is identical to the **set_checkbox()** function above.
+
+::
+
+	<input type="radio" name="myradio" value="1" <?php echo  set_radio('myradio', '1', TRUE); ?> /> 
+	<input type="radio" name="myradio" value="2" <?php echo  set_radio('myradio', '2'); ?> />

+###########
+HTML Helper
+###########
+
+The HTML Helper file contains functions that assist in working with
+HTML.
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code::
+
+	$this->load->helper('html');
+
+The following functions are available:
+
+br()
+====
+
+Generates line break tags (<br />) based on the number you submit.
+Example::
+
+	echo br(3);
+
+The above would produce: <br /><br /><br />
+
+heading()
+=========
+
+Lets you create HTML <h1> tags. The first parameter will contain the
+data, the second the size of the heading. Example::
+
+	echo heading('Welcome!', 3);
+
+The above would produce: <h3>Welcome!</h3>
+
+Additionally, in order to add attributes to the heading tag such as HTML
+classes, ids or inline styles, a third parameter is available.
+
+::
+
+	echo heading('Welcome!', 3, 'class="pink"')
+
+The above code produces: <h3 class="pink">Welcome!<<h3>
+
+img()
+=====
+
+Lets you create HTML <img /> tags. The first parameter contains the
+image source. Example
+
+::
+
+	echo img('images/picture.jpg'); // gives <img src="http://site.com/images/picture.jpg" />
+
+There is an optional second parameter that is a TRUE/FALSE value that
+specifics if the src should have the page specified by
+$config['index_page'] added to the address it creates. Presumably, this
+would be if you were using a media controller.
+
+::
+
+	echo img('images/picture.jpg', TRUE); // gives <img src="http://site.com/index.php/images/picture.jpg" alt="" />
+
+
+Additionally, an associative array can be passed to the img() function
+for complete control over all attributes and values. If an alt attribute
+is not provided, CodeIgniter will generate an empty string.
+
+::
+
+	$image_properties = array(               
+		'src' 	=> 'images/picture.jpg',               
+		'alt' 	=> 'Me, demonstrating how to eat 4 slices of pizza at one time',  
+		'class' => 'post_images',               
+		'width' => '200',               
+		'height'=> '200',               
+		'title' => 'That was quite a night',               
+		'rel' 	=> 'lightbox'
+	);
+
+		img($image_properties);     // <img src="http://site.com/index.php/images/picture.jpg" alt="Me, demonstrating how to eat 4 slices of pizza at one time" class="post_images" width="200" height="200" title="That was quite a night" rel="lightbox" />
+
+
+link_tag()
+===========
+
+Lets you create HTML <link /> tags. This is useful for stylesheet links,
+as well as other links. The parameters are href, with optional rel,
+type, title, media and index_page. index_page is a TRUE/FALSE value
+that specifics if the href should have the page specified by
+$config['index_page'] added to the address it creates.
+
+::
+
+	 echo link_tag('css/mystyles.css'); // gives <link href="http://site.com/css/mystyles.css" rel="stylesheet" type="text/css" />
+
+
+Further examples
+
+::
+
+	echo link_tag('favicon.ico', 'shortcut icon', 'image/ico');     // <link href="http://site.com/favicon.ico" rel="shortcut icon" type="image/ico" />
+
+	echo link_tag('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');     // <link href="http://site.com/feed" rel="alternate" type="application/rss+xml" title="My RSS Feed" />
+
+Additionally, an associative array can be passed to the link() function
+for complete control over all attributes and values.
+
+::
+
+	$link = array(               
+		'href' 	=> 'css/printer.css',               
+		'rel' 	=> 'stylesheet',               
+		'type' 	=> 'text/css',               
+		'media' => 'print'
+	);
+
+	echo link_tag($link);     // <link href="http://site.com/css/printer.css" rel="stylesheet" type="text/css" media="print" />
+
+
+nbs()
+=====
+
+Generates non-breaking spaces (&nbsp;) based on the number you submit.
+Example
+
+::
+
+	echo nbs(3);
+
+The above would produce
+
+::
+
+	&nbsp;&nbsp;&nbsp;
+
+ol() and ul()
+=============
+
+Permits you to generate ordered or unordered HTML lists from simple or
+multi-dimensional arrays. Example
+
+::
+
+	$this->load->helper('html');
+
+	$list = array(             
+		'red',              
+		'blue',              
+		'green',             
+		'yellow'             
+	);
+
+	$attributes = array(                     
+		'class' => 'boldlist',                     
+		'id'    => 'mylist'                    
+	);
+
+	echo ul($list, $attributes);
+
+The above code will produce this
+
+::
+
+	 <ul class="boldlist" id="mylist">   
+		<li>red</li>   
+		<li>blue</li>   
+		<li>green</li>   
+		<li>yellow</li>
+	</ul>
+
+Here is a more complex example, using a multi-dimensional array
+
+::
+
+	$this->load->helper('html');
+
+	$attributes = array(                     
+		'class' => 'boldlist',                     
+		'id'    => 'mylist'                     
+	);
+
+	$list = array(             
+		'colors'  => array(                                 
+			'red',                                 
+			'blue',                                 
+			'green'                             
+		),
+		'shapes'  => array(                                 
+			'round',                                  
+			'square',                                 
+			'circles' => array(                                             
+				'ellipse',
+				'oval',
+				'sphere'
+			)                             
+		),             
+		'moods'  => array(                                 
+			'happy',                                  
+			'upset' => array( 	                                       
+				'defeated' => array(
+					'dejected',                
+					'disheartened',
+					'depressed'
+				),
+				'annoyed',
+				'cross',
+				'angry'
+			)
+		)
+	);
+
+	echo ul($list, $attributes);
+
+The above code will produce this
+
+::
+
+	<ul class="boldlist" id="mylist">   
+		<li>colors     
+			<ul>       
+				<li>red</li>       
+				<li>blue</li>       
+				<li>green</li>     
+			</ul>   
+		</li>   
+		<li>shapes     
+			<ul>       
+				<li>round</li>       
+				<li>suare</li>       
+				<li>circles         
+					<ul>           
+						<li>elipse</li>           
+						<li>oval</li>           
+						<li>sphere</li>         
+					</ul>       
+				</li>     
+			</ul>   
+		</li>   
+		<li>moods     
+			<ul>       
+				<li>happy</li>       
+				<li>upset         
+					<ul>           
+						<li>defeated             
+							<ul>               
+								<li>dejected</li>
+								<li>disheartened</li>
+								<li>depressed</li>
+							</ul>
+						</li>
+						<li>annoyed</li>
+						<li>cross</li>           
+						<li>angry</li>         
+					</ul>       
+				</li>     
+			</ul>   
+		</li>
+	</ul>
+
+meta()
+======
+
+Helps you generate meta tags. You can pass strings to the function, or
+simple arrays, or multidimensional ones. Examples
+
+::
+
+	echo meta('description', 'My Great site');
+	// Generates:  <meta name="description" content="My Great Site" />
+
+	echo meta('Content-type', 'text/html; charset=utf-8', 'equiv');
+	// Note the third parameter.  Can be "equiv" or "name"
+	// Generates:  <meta http-equiv="Content-type" content="text/html; charset=utf-8" />
+
+	echo meta(array('name' => 'robots', 'content' => 'no-cache'));
+	// Generates:  <meta name="robots" content="no-cache" />
+
+	$meta = array(         
+		array(
+			'name' => 'robots',
+			'content' => 'no-cache'
+		),
+		array(
+			'name' => 'description',
+			'content' => 'My Great Site'

+
+doctype()
+=========
+
+Helps you generate document type declarations, or DTD's. XHTML 1.0
+Strict is used by default, but many doctypes are available.
+
+::
+
+	echo doctype(); // <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

+Smiley Helper
+#############
+
+The Smiley Helper file contains functions that let you manage smileys
+(emoticons).
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+	$this->load->helper('smiley');
+
+Overview
+========
+
+The Smiley helper has a renderer that takes plain text simileys, like
+:-) and turns them into a image representation, like |smile!|
+
+It also lets you display a set of smiley images that when clicked will
+be inserted into a form field. For example, if you have a blog that
+allows user commenting you can show the smileys next to the comment
+form. Your users can click a desired smiley and with the help of some
+JavaScript it will be placed into the form field.
+
+Clickable Smileys Tutorial
+==========================
+
+Here is an example demonstrating how you might create a set of clickable
+smileys next to a form field. This example requires that you first
+download and install the smiley images, then create a controller and the
+View as described.
+
+.. important:: Before you begin, please `download the smiley images <http://codeigniter.com/download_files/smileys.zip>`_
+	and put them in a publicly accessible place on your server. This helper
+	also assumes you have the smiley replacement array located at
+	`application/config/smileys.php`
+
+The Controller
+--------------
+
+In your `application/controllers/` folder, create a file called
+smileys.php and place the code below in it.
+
+.. important:: Change the URL in the `get_clickable_smileys()`
+	function below so that it points to your smiley folder.
+
+You'll notice that in addition to the smiley helper we are using the :doc:`Table Class <../libraries/table>`.
+
+::
+
+	<?php
+
+	class Smileys extends CI_Controller {
+
+		function index()
+		{
+			$this->load->helper('smiley');
+			$this->load->library('table');
+
+			$image_array = get_clickable_smileys('http://example.com/images/smileys/', 'comments');
+			$col_array = $this->table->make_columns($image_array, 8);
+
+			$data['smiley_table'] = $this->table->generate($col_array);
+			$this->load->view('smiley_view', $data);
+		}
+	}
+
+In your `application/views/` folder, create a file called `smiley_view.php`
+and place this code in it:
+
+::
+
+	<html>
+		<head>
+			<title>Smileys</title>
+			<?php echo smiley_js(); ?>
+		</head>
+		<body>
+			<form name="blog">
+				<textarea name="comments" id="comments" cols="40" rows="4"></textarea>
+			</form>
+			<p>Click to insert a smiley!</p>
+			<?php echo $smiley_table; ?> </body> </html>
+			When you have created the above controller and view, load it by visiting http://www.example.com/index.php/smileys/
+		</body>
+	</html>
+
+Field Aliases
+-------------
+
+When making changes to a view it can be inconvenient to have the field
+id in the controller. To work around this, you can give your smiley
+links a generic name that will be tied to a specific id in your view.
+
+::
+
+	$image_array = get_smiley_links("http://example.com/images/smileys/", "comment_textarea_alias");
+
+To map the alias to the field id, pass them both into the `smiley_js`
+function
+
+::
+
+	$image_array = smiley_js("comment_textarea_alias", "comments");
+
+******************
+Function Reference
+******************
+
+get_clickable_smileys()
+=======================
+
+Returns an array containing your smiley images wrapped in a clickable
+link. You must supply the URL to your smiley folder and a field id or
+field alias.
+
+::
+
+	$image_array = get_smiley_links("http://example.com/images/smileys/", "comment");
+
+Note: Usage of this function without the second parameter, in
+combination with `js_insert_smiley` has been deprecated.
+
+smiley_js()
+===========
+
+Generates the JavaScript that allows the images to be clicked and
+inserted into a form field. If you supplied an alias instead of an id
+when generating your smiley links, you need to pass the alias and
+corresponding form id into the function. This function is designed to be
+placed into the <head> area of your web page.
+
+::
+
+	<?php echo smiley_js(); ?>
+
+Note: This function replaces `js_insert_smiley`, which has been
+deprecated.
+
+parse_smileys()
+===============
+
+Takes a string of text as input and replaces any contained plain text
+smileys into the image equivalent. The first parameter must contain your
+string, the second must contain the URL to your smiley folder
+
+::
+
+	$str = 'Here are some simileys: :-)  ;-)';
+	$str = parse_smileys($str, "http://example.com/images/smileys/");
+	echo $str;
+
+
+.. |smile!| image:: ../images/smile.gif

+String Helper
+#############
+
+The String Helper file contains functions that assist in working with
+strings.
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+	$this->load->helper('string');
+
+The following functions are available:
+
+random_string()
+===============
+
+Generates a random string based on the type and length you specify.
+Useful for creating passwords or generating random hashes.
+
+The first parameter specifies the type of string, the second parameter
+specifies the length. The following choices are available:
+
+alpha, alunum, numeric, nozero, unique, md5, encrypt and sha1
+
+-  **alpha**: A string with lower and uppercase letters only.
+-  **alnum**: Alpha-numeric string with lower and uppercase characters.
+-  **numeric**: Numeric string.
+-  **nozero**: Numeric string with no zeros.
+-  **unique**: Encrypted with MD5 and uniqid(). Note: The length
+   parameter is not available for this type. Returns a fixed length 32
+   character string.
+-  **sha1**: An encrypted random number based on do_hash() from the
+   :doc:`security helper <security_helper>`.
+
+Usage example
+
+::
+
+	echo random_string('alnum', 16);
+
+increment_string()
+==================
+
+Increments a string by appending a number to it or increasing the
+number. Useful for creating "copies" or a file or duplicating database
+content which has unique titles or slugs.
+
+Usage example
+
+::
+
+	echo increment_string('file', '_'); // "file_1"
+	echo increment_string('file', '-', 2); // "file-2"
+	echo increment_string('file-4'); // "file-5"
+
+alternator()
+============
+
+Allows two or more items to be alternated between, when cycling through
+a loop. Example
+
+::
+
+	for ($i = 0; $i < 10; $i++)
+	{     
+		echo alternator('string one', 'string two');
+	}
+
+You can add as many parameters as you want, and with each iteration of
+your loop the next item will be returned.
+
+::
+
+	for ($i = 0; $i < 10; $i++)
+	{     
+		echo alternator('one', 'two', 'three', 'four', 'five');
+	}
+
+.. note:: To use multiple separate calls to this function simply call the
+	function with no arguments to re-initialize.
+
+repeater()
+==========
+
+Generates repeating copies of the data you submit. Example
+
+::
+
+	$string = "\n"; echo repeater($string, 30);
+
+The above would generate 30 newlines.
+
+reduce_double_slashes()
+=======================
+
+Converts double slashes in a string to a single slash, except those
+found in http://. Example
+
+::
+
+	$string = "http://example.com//index.php";
+	echo reduce_double_slashes($string); // results in "http://example.com/index.php"
+
+trim_slashes()
+==============
+
+Removes any leading/trailing slashes from a string. Example
+
+::
+
+	$string = "/this/that/theother/";
+	echo trim_slashes($string); // results in this/that/theother
+
+
+reduce_multiples()
+==================
+
+Reduces multiple instances of a particular character occuring directly
+after each other. Example::
+
+	$string = "Fred, Bill,, Joe, Jimmy";
+	$string = reduce_multiples($string,","); //results in "Fred, Bill, Joe, Jimmy"
+
+The function accepts the following parameters:
+
+::
+
+	reduce_multiples(string: text to search in, string: character to reduce, boolean: whether to remove the character from the front and end of the string)
+
+The first parameter contains the string in which you want to reduce the
+multiplies. The second parameter contains the character you want to have
+reduced. The third parameter is FALSE by default; if set to TRUE it will
+remove occurences of the character at the beginning and the end of the
+string. Example:
+
+::
+
+	$string = ",Fred, Bill,, Joe, Jimmy,";
+	$string = reduce_multiples($string, ", ", TRUE); //results in "Fred, Bill, Joe, Jimmy"
+
+
+quotes_to_entities()
+====================
+
+Converts single and double quotes in a string to the corresponding HTML
+entities. Example
+
+::
+
+	$string = "Joe's \"dinner\"";
+	$string = quotes_to_entities($string); //results in "Joe&#39;s &quot;dinner&quot;"
+
+strip_quotes()
+==============
+
+Removes single and double quotes from a string. Example::
+
+	$string = "Joe's \"dinner\"";
+	$string = strip_quotes($string); //results in "Joes dinner"

+undeclared this helper uses an ellipsis.
+
+ascii_to_entities()
+===================
+
+Converts ASCII values to character entities, including high ASCII and MS
+Word characters that can cause problems when used in a web page, so that
+they can be shown consistently regardless of browser settings or stored
+reliably in a database. There is some dependence on your server's
+supported character sets, so it may not be 100% reliable in all cases,
+but for the most part it should correctly identify characters outside
+the normal range (like accented characters). Example
+
+::
+
+	$string = ascii_to_entities($string);
+
+entities_to_ascii()
+===================
+
+This function does the opposite of the previous one; it turns character
+entities back into ASCII.
+
+convert_accented_characters()
+=============================
+
+Transliterates high ASCII characters to low ASCII equivalents, useful
+when non-English characters need to be used where only standard ASCII
+characters are safely used, for instance, in URLs.
+
+::
+
+	$string = convert_accented_characters($string);
+
+This function uses a companion config file
+`application/config/foreign_chars.php` to define the to and from array
+for transliteration.
+
+word_censor()
+=============
+
+Enables you to censor words within a text string. The first parameter
+will contain the original string. The second will contain an array of
+words which you disallow. The third (optional) parameter can contain a
+replacement value for the words. If not specified they are replaced with
+pound signs: ####. Example
+
+::
+
+	$disallowed = array('darn', 'shucks', 'golly', 'phooey');
+	$string = word_censor($string, $disallowed, 'Beep!');
+
+highlight_code()
+================
+
+Colorizes a string of code (PHP, HTML, etc.). Example::
+
+	$string = highlight_code($string);
+
+The function uses PHP's highlight_string() function, so the colors used
+are the ones specified in your php.ini file.
+
+highlight_phrase()
+==================
+
+Will highlight a phrase within a text string. The first parameter will
+contain the original string, the second will contain the phrase you wish
+to highlight. The third and fourth parameters will contain the
+opening/closing HTML tags you would like the phrase wrapped in. Example
+
+::
+
+	$string = "Here is a nice text string about nothing in particular.";
+	$string = highlight_phrase($string, "nice text", '<span style="color:#990000">', '</span>');
+
+The above text returns:
+
+Here is a nice text string about nothing in particular.
+
+word_wrap()
+===========
+
+Wraps text at the specified **character** count while maintaining
+complete words. Example
+
+::
+
+	$string = "Here is a simple string of text that will help us demonstrate this function.";
+	echo word_wrap($string, 25);
+
+	// Would produce:  Here is a simple string of text that will help us demonstrate this function
+
+ellipsize()
+===========
+
+This function will strip tags from a string, split it at a defined
+maximum length, and insert an ellipsis.
+
+The first parameter is the string to ellipsize, the second is the number
+of characters in the final string. The third parameter is where in the
+string the ellipsis should appear from 0 - 1, left to right. For
+example. a value of 1 will place the ellipsis at the right of the
+string, .5 in the middle, and 0 at the left.
+
+An optional forth parameter is the kind of ellipsis. By default,
+&hellip; will be inserted.
+
+::
+
+	$str = 'this_string_is_entirely_too_long_and_might_break_my_design.jpg';
+	echo ellipsize($str, 32, .5);
+
+Produces:
+
+::
+
+	this_string_is_e&hellip;ak_my_design.jpg

+Typography Helper
+#################
+
+The Typography Helper file contains functions that help your format text
+in semantically relevant ways.
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+	$this->load->helper('typography');
+
+The following functions are available:
+
+auto_typography()
+=================
+
+Formats text so that it is semantically and typographically correct
+HTML. Please see the :doc:`Typography Class <../libraries/typography>`
+for more info.
+
+Usage example::
+
+	$string = auto_typography($string);
+
+.. note:: Typographic formatting can be processor intensive, particularly if
+	you have a lot of content being formatted. If you choose to use this
+	function you may want to consider `caching </general/caching>` your pages.
+
+nl2br_except_pre()
+==================
+
+Converts newlines to <br /> tags unless they appear within <pre> tags.
+This function is identical to the native PHP nl2br() function, except
+that it ignores <pre> tags.
+
+Usage example
+
+::
+
+	$string = nl2br_except_pre($string);

+##########
+URL Helper
+##########
+
+The URL Helper file contains functions that assist in working with URLs.
+
+.. contents:: Page Contents
+
+Loading this Helper
+===================
+
+This helper is loaded using the following code
+
+::
+
+	$this->load->helper('url');
+
+The following functions are available:
+
+site_url()
+==========
+
+Returns your site URL, as specified in your config file. The index.php
+file (or whatever you have set as your site index_page in your config
+file) will be added to the URL, as will any URI segments you pass to the
+function, and the url_suffix as set in your config file.
+
+You are encouraged to use this function any time you need to generate a
+local URL so that your pages become more portable in the event your URL
+changes.
+
+Segments can be optionally passed to the function as a string or an
+array. Here is a string example
+
+::
+
+	echo site_url("news/local/123");
+
+The above example would return something like:
+http://example.com/index.php/news/local/123
+
+Here is an example of segments passed as an array
+
+::
+
+	$segments = array('news', 'local', '123');
+	echo site_url($segments);
+
+base_url()
+===========
+
+Returns your site base URL, as specified in your config file. Example
+
+::
+
+	echo base_url();
+
+This function returns the same thing as `site_url`, without the
+index_page or url_suffix being appended.
+
+Also like site_url, you can supply segments as a string or an array.
+Here is a string example
+
+::
+
+	echo base_url("blog/post/123");
+
+The above example would return something like:
+http://example.com/blog/post/123
+
+This is useful because unlike `site_url()`, you can supply a string to a
+file, such as an image or stylesheet. For example
+
+::
+
+	echo base_url("images/icons/edit.png");
+
+This would give you something like:
+http://example.com/images/icons/edit.png
+
+current_url()
+=============
+
+Returns the full URL (including segments) of the page being currently
+viewed.
+
+uri_string()
+============
+
+Returns the URI segments of any page that contains this function. For
+example, if your URL was this
+
+::
+
+	http://some-site.com/blog/comments/123
+
+The function would return
+
+::
+
+	/blog/comments/123
+
+index_page()
+============
+
+Returns your site "index" page, as specified in your config file.
+Example
+
+::
+
+	echo index_page();
+
+anchor()
+========
+
+Creates a standard HTML anchor link based on your local site URL
+
+::
+
+	<a href="http://example.com">Click Here</a>
+
+The tag has three optional parameters
+
+::
+
+	anchor(uri segments, text, attributes)
+
+The first parameter can contain any segments you wish appended to the
+URL. As with the site_url() function above, segments can be a string or
+an array.
+
+.. note:: If you are building links that are internal to your application
+	do not include the base URL (http://...). This will be added automatically
+	from the information specified in your config file. Include only the
+	URI segments you wish appended to the URL.
+
+The second segment is the text you would like the link to say. If you
+leave it blank, the URL will be used.
+
+The third parameter can contain a list of attributes you would like
+added to the link. The attributes can be a simple string or an
+associative array.
+
+Here are some examples
+
+::
+
+	echo anchor('news/local/123', 'My News', 'title="News title"');
+
+Would produce: <a href="http://example.com/index.php/news/local/123"
+title="News title">My News</a>
+
+::
+
+	echo anchor('news/local/123', 'My News', array('title' => 'The best news!'));
+
+Would produce: <a href="http://example.com/index.php/news/local/123"
+title="The best news!">My News</a>
+
+anchor_popup()
+==============
+
+Nearly identical to the anchor() function except that it opens the URL
+in a new window. You can specify JavaScript window attributes in the
+third parameter to control how the window is opened. If the third
+parameter is not set it will simply open a new window with your own
+browser settings. Here is an example with attributes
+
+::
+
+	$atts = array(               
+		'width'      => '800',               
+		'height'     => '600',               
+		'scrollbars' => 'yes',               
+		'status'     => 'yes',               
+		'resizable'  => 'yes',               
+		'screenx'    => '0',               
+		'screeny'    => '0'             
+	);
+
+	echo anchor_popup('news/local/123', 'Click Me!', $atts);
+
+Note: The above attributes are the function defaults so you only need to
+set the ones that are different from what you need. If you want the
+function to use all of its defaults simply pass an empty array in the
+third parameter
+
+::
+
+	echo anchor_popup('news/local/123', 'Click Me!', array());
+
+mailto()
+========
+
+Creates a standard HTML email link. Usage example
+
+::
+
+	echo mailto('me@my-site.com', 'Click Here to Contact Me');
+
+As with the anchor() tab above, you can set attributes using the third
+parameter.
+
+safe_mailto()
+=============
+
+Identical to the above function except it writes an obfuscated version
+of the mailto tag using ordinal numbers written with JavaScript to help
+prevent the email address from being harvested by spam bots.
+
+auto_link()
+===========
+
+Automatically turns URLs and email addresses contained in a string into
+links. Example
+
+::
+
+	$string = auto_link($string);
+
+The second parameter determines whether URLs and emails are converted or
+just one or the other. Default behavior is both if the parameter is not
+specified. Email links are encoded as safe_mailto() as shown above.
+
+Converts only URLs
+
+::
+
+	$string = auto_link($string, 'url');
+
+Converts only Email addresses
+
+::
+
+	$string = auto_link($string, 'email');
+
+The third parameter determines whether links are shown in a new window.
+The value can be TRUE or FALSE (boolean)
+
+::
+
+	$string = auto_link($string, 'both', TRUE);
+
+url_title()
+===========
+
+Takes a string as input and creates a human-friendly URL string. This is
+useful if, for example, you have a blog in which you'd like to use the
+title of your entries in the URL. Example
+
+::
+
+	$title = "What's wrong with CSS?";
+	$url_title = url_title($title);  // Produces:  Whats-wrong-with-CSS
+
+The second parameter determines the word delimiter. By default dashes
+are used. Options are: dash, or underscore
+
+::
+
+	$title = "What's wrong with CSS?";
+	$url_title = url_title($title, 'underscore');  // Produces:  Whats_wrong_with_CSS
+
+The third parameter determines whether or not lowercase characters are
+forced. By default they are not. Options are boolean TRUE/FALSE
+
+::
+
+	$title = "What's wrong with CSS?";
+	$url_title = url_title($title, 'underscore', TRUE);  // Produces:  whats_wrong_with_css
+
+prep_url()
+----------
+
+This function will add http:// in the event that a scheme is missing
+from a URL. Pass the URL string to the function like this
+
+::
+
+	$url = "example.com";
+	$url = prep_url($url);
+
+redirect()
+==========
+
+Does a "header redirect" to the URI specified. If you specify the full
+site URL that link will be build, but for local links simply providing
+the URI segments to the controller you want to direct to will create the
+link. The function will build the URL based on your config file values.
+
+The optional second parameter allows you to choose between the
+"location" method (default) or the "refresh" method. Location is faster,
+but on Windows servers it can sometimes be a problem. The optional third
+parameter allows you to send a specific HTTP Response Code - this could
+be used for example to create 301 redirects for search engine purposes.
+The default Response Code is 302. The third parameter is *only*
+available with 'location' redirects, and not 'refresh'. Examples
+
+::
+
+	if ($logged_in == FALSE)
+	{      
+		redirect('/login/form/', 'refresh');
+	}
+
+	// with 301 redirect
+	redirect('/article/13', 'location', 301);
+
+.. note:: In order for this function to work it must be used before anything
+	is outputted to the browser since it utilizes server headers.
+
+.. note:: For very fine grained control over headers, you should use the
+	`Output Library </libraries/output>` set_header() function.

+Welcome to CodeIgniter
+======================
+
+CodeIgniter is an Application Development Framework - a toolkit - for
+people who build web sites using PHP. Its goal is to enable you to
+develop projects much faster than you could if you were writing code
+from scratch, by providing a rich set of libraries for commonly needed
+tasks, as well as a simple interface and logical structure to access
+these libraries. CodeIgniter lets you creatively focus on your project
+by minimizing the amount of code needed for a given task.
+
+Who is CodeIgniter For?
+=======================
+
+CodeIgniter is right for you if:
+
+-  You want a framework with a small footprint.
+-  You need exceptional performance.
+-  You need broad compatibility with standard hosting accounts that run
+   a variety of PHP versions and configurations.
+-  You want a framework that requires nearly zero configuration.
+-  You want a framework that does not require you to use the command
+   line.
+-  You want a framework that does not require you to adhere to
+   restrictive coding rules.
+-  You are not interested in large-scale monolithic libraries like PEAR.
+-  You do not want to be forced to learn a templating language (although
+   a template parser is optionally available if you desire one).
+-  You eschew complexity, favoring simple solutions.
+-  You need clear, thorough documentation.

+#########################
+Installation Instructions
+#########################
+
+CodeIgniter is installed in four steps:
+
+#. Unzip the package.
+#. Upload the CodeIgniter folders and files to your server. Normally the
+   index.php file will be at your root.
+#. Open the application/config/config.php file with a text editor and
+   set your base URL. If you intend to use encryption or sessions, set
+   your encryption key.
+#. If you intend to use a database, open the
+   application/config/database.php file with a text editor and set your
+   database settings.
+
+If you wish to increase security by hiding the location of your
+CodeIgniter files you can rename the system and application folders to
+something more private. If you do rename them, you must open your main
+index.php file and set the $system_path and $application_folder
+variables at the top of the file with the new name you've chosen.
+
+For the best security, both the system and any application folders
+should be placed above web root so that they are not directly accessible
+via a browser. By default, .htaccess files are included in each folder
+to help prevent direct access, but it is best to remove them from public
+access entirely in case the web server configuration changes or doesn't
+abide by the .htaccess.
+
+If you would like to keep your views public it is also possible to move
+the views folder out of your application folder.
+
+After moving them, open your main index.php file and set the
+$system_path, $application_folder and $view_folder variables,
+preferably with a full path, e.g. '/www/MyUser/system'.
+
+One additional measure to take in production environments is to disable
+PHP error reporting and any other development-only functionality. In
+CodeIgniter, this can be done by setting the ENVIRONMENT constant, which
+is more fully described on the :doc:`security
+page <../general/security>`.
+
+That's it!
+
+If you're new to CodeIgniter, please read the :doc:`Getting
+Started <../overview/getting_started>` section of the User Guide
+to begin learning how to build dynamic PHP applications. Enjoy!

+###############
+Troubleshooting
+###############
+
+If you find that no matter what you put in your URL only your default
+page is loading, it might be that your server does not support the
+PATH_INFO variable needed to serve search-engine friendly URLs. As a
+first step, open your application/config/config.php file and look for
+the URI Protocol information. It will recommend that you try a couple
+alternate settings. If it still doesn't work after you've tried this
+you'll need to force CodeIgniter to add a question mark to your URLs. To
+do this open your application/config/config.php file and change this::
+
+	$config['index_page'] = "index.php";
+
+To this::
+
+	$config['index_page'] = "index.php?";

+#########################
+Upgrading from 1.2 to 1.3
+#########################
+
+.. note:: The instructions on this page assume you are running version
+	1.2. If you have not upgraded to that version please do so first.
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace the following directories in your "system" folder with the new
+versions:
+
+.. note:: If you have any custom developed files in these folders please
+	make copies of them first.
+
+-  application/**models**/ (new for 1.3)
+-  codeigniter (new for 1.3)
+-  drivers
+-  helpers
+-  init
+-  language
+-  libraries
+-  plugins
+-  scaffolding
+
+Step 2: Update your error files
+===============================
+
+Version 1.3 contains two new error templates located in
+application/errors, and for naming consistency the other error templates
+have been renamed.
+
+If you **have not** customized any of the error templates simply replace
+this folder:
+
+-  application/errors/
+
+If you **have** customized your error templates, rename them as follows:
+
+-  404.php = error_404.php
+-  error.php = error_general.php
+-  error_db.php (new)
+-  error_php.php (new)
+
+Step 3: Update your index.php file
+==================================
+
+Please open your main index.php file (located at your root). At the very
+bottom of the file, change this::
+
+	require_once BASEPATH.'libraries/Front_controller'.EXT;
+
+To this::
+
+	require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;
+
+Step 4: Update your config.php file
+===================================
+
+Open your application/config/config.php file and add these new items::
+
+
+    /*
+    |------------------------------------------------
+    | URL suffix
+    |------------------------------------------------
+    |
+    | This option allows you to add a suffix to all URLs.
+    | For example, if a URL is this:
+    |
+    | example.com/index.php/products/view/shoes
+    |
+    | You can optionally add a suffix, like ".html",
+    | making the page appear to be of a certain type:
+    |
+    | example.com/index.php/products/view/shoes.html
+    |
+    */
+    $config['url_suffix'] = "";
+
+
+    /*
+    |------------------------------------------------
+    | Enable Query Strings
+    |------------------------------------------------
+    |
+    | By default CodeIgniter uses search-engine and
+    | human-friendly segment based URLs:
+    |
+    | example.com/who/what/where/
+    |
+    | You can optionally enable standard query string
+    | based URLs:
+    |
+    | example.com?who=me&what=something&where=here
+    |
+    | Options are: TRUE or FALSE (boolean)
+    |
+    | The two other items let you set the query string "words"
+    | that will invoke your controllers and functions:
+    | example.com/index.php?c=controller&m=function
+    |
+    */
+    $config['enable_query_strings'] = FALSE;
+    $config['controller_trigger'] = 'c';
+    $config['function_trigger'] = 'm';
+
+Step 5: Update your database.php file
+=====================================
+
+Open your application/config/database.php file and add these new items::
+
+
+    $db['default']['dbprefix'] = "";
+    $db['default']['active_r'] = TRUE;
+
+Step 6: Update your user guide
+==============================
+
+Please also replace your local copy of the user guide with the new
+version.

+Step 2: Update your Models
+==========================
+
+If you are **NOT** using CodeIgniter's
+:doc:`Models <../general/models>` feature disregard this step.
+
+As of version 1.3.3, CodeIgniter does **not** connect automatically to
+your database when a model is loaded. This allows you greater
+flexibility in determining which databases you would like used with your
+models. If your application is not connecting to your database prior to
+a model being loaded you will have to update your code. There are
+several options for connecting, :doc:`as described
+here <../general/models>`.
+
+Step 3: Update your user guide

+Upgrading from 1.6.3 to 1.7.0
+#############################
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace these files and directories in your "system" folder with the new
+versions:
+
+-  system/codeigniter
+-  system/database
+-  system/helpers
+-  system/language
+-  system/libraries
+
+.. note:: If you have any custom developed files in these folders please
+	make copies of them first.
+
+Step 2: Update your Session Table
+=================================
+
+If you are using the Session class in your application, AND if you are
+storing session data to a database, you must add a new column named
+user_data to your session table. Here is an example of what this column
+might look like for MySQL::
+
+	user_data text NOT NULL
+
+To add this column you will run a query similar to this::
+
+	ALTER TABLE `ci_sessions` ADD `user_data` text NOT NULL
+
+You'll find more information regarding the new Session functionality in
+the :doc:`Session class <../libraries/sessions>` page.
+
+Step 3: Update your Validation Syntax
+=====================================
+
+This is an **optional**, but recommended step, for people currently
+using the Validation class. CI 1.7 introduces a new :doc:`Form Validation
+class <../libraries/form_validation>`, which deprecates the old
+Validation library. We have left the old one in place so that existing
+applications that use it will not break, but you are encouraged to
+migrate to the new version as soon as possible. Please read the user
+guide carefully as the new library works a little differently, and has
+several new features.
+
+Step 4: Update your user guide
+==============================
+
+Please replace your local copy of the user guide with the new version,
+including the image files.

+#############################
+Upgrading from 1.7.2 to 2.0.0
+#############################
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace all files and directories in your "system" folder **except**
+your application folder.
+
+.. note:: If you have any custom developed files in these folders please
+	make copies of them first.
+
+Step 2: Adjust get_dir_file_info() where necessary
+=====================================================
+
+Version 2.0.0 brings a non-backwards compatible change to
+get_dir_file_info() in the :doc:`File
+Helper <../helpers/file_helper>`. Non-backwards compatible changes
+are extremely rare in CodeIgniter, but this one we feel was warranted
+due to how easy it was to create serious server performance issues. If
+you *need* recursiveness where you are using this helper function,
+change such instances, setting the second parameter, $top_level_only
+to FALSE::
+
+	get_dir_file_info('/path/to/directory', FALSE);
+
+Step 3: Convert your Plugins to Helpers
+=======================================
+
+2.0.0 gets rid of the "Plugin" system as their functionality was
+identical to Helpers, but non-extensible. You will need to rename your
+plugin files from filename_pi.php to filename_helper.php, move them to
+your helpers folder, and change all instances of::
+
+	$this->load->plugin('foo');
+
+to ::
+
+	$this->load->helper('foo');
+
+
+Step 4: Update stored encrypted data
+====================================
+
+.. note:: If your application does not use the Encryption library, does
+	not store Encrypted data permanently, or is on an environment that does
+	not support Mcrypt, you may skip this step.
+
+The Encryption library has had a number of improvements, some for
+encryption strength and some for performance, that has an unavoidable
+consequence of making it no longer possible to decode encrypted data
+produced by the original version of this library. To help with the
+transition, a new method has been added, encode_from_legacy() that
+will decode the data with the original algorithm and return a re-encoded
+string using the improved methods. This will enable you to easily
+replace stale encrypted data with fresh in your applications, either on
+the fly or en masse.
+
+Please read `how to use this
+method <../libraries/encryption.html#legacy>`_ in the Encryption library
+documentation.
+
+Step 5: Remove loading calls for the compatibility helper.
+==========================================================
+
+The compatibility helper has been removed from the CodeIgniter core. All
+methods in it should be natively available in supported PHP versions.
+
+Step 6: Update Class extension
+==============================
+
+All core classes are now prefixed with CI\_. Update Models and
+Controllers to extend CI_Model and CI_Controller, respectively.
+
+Step 7: Update Parent Constructor calls
+=======================================
+
+All native CodeIgniter classes now use the PHP 5 \__construct()
+convention. Please update extended libraries to call
+parent::\__construct().
+
+Step 8: Update your user guide
+==============================
+
+Please replace your local copy of the user guide with the new version,
+including the image files.

+submitting to the default controller was the expected behavior it will

+=========================
+

+
+csrf_token_name and csrf_hash have changed to protected class

+
+If your index.php file has internal modifications, please add your
+modifications to the new file and use it.
+
+Step 3: Replace config/user_agents.php
+=======================================
+
+This config file has been updated to contain more user agent types,
+please copy it to application/config/user_agents.php.
+
+Step 4: Change references of the EXT constant to ".php"
+=======================================================
+
+.. note:: The EXT Constant has been marked as deprecated, but has not
+	been removed from the application. You are encouraged to make the
+	changes sooner rather than later.
+
+Step 5: Remove APPPATH.'third_party' from autoload.php
+=======================================================
+
+Open application/config/autoload.php, and look for the following::

+
+If you are using database sessions with the CI Session Library, please
+update your ci_sessions database table as follows::

+###################################
+Upgrading From Beta 1.0 to Beta 1.1
+###################################
+
+To upgrade to Beta 1.1 please perform the following steps:
+
+Step 1: Replace your index file
+===============================
+
+Replace your main index.php file with the new index.php file. Note: If
+you have renamed your "system" folder you will need to edit this info in
+the new file.
+
+Step 2: Relocate your config folder
+===================================
+
+This version of CodeIgniter now permits multiple sets of "applications"
+to all share a common set of backend files. In order to enable each
+application to have its own configuration values, the config directory
+must now reside inside of your application folder, so please move it
+there.
+
+Step 3: Replace directories
+===========================
+
+Replace the following directories with the new versions:
+
+-  drivers
+-  helpers
+-  init
+-  libraries
+-  scaffolding
+
+Step 4: Add the calendar language file
+======================================
+
+There is a new language file corresponding to the new calendaring class
+which must be added to your language folder. Add the following item to
+your version: language/english/calendar_lang.php
+
+Step 5: Edit your config file
+=============================
+
+The original application/config/config.php file has a typo in it Open
+the file and look for the items related to cookies::
+
+	$conf['cookie_prefix']    = ""; $conf['cookie_domain']  = ""; $conf['cookie_path']    = "/";
+
+Change the array name from $conf to $config, like this::
+
+	$config['cookie_prefix']  = ""; $config['cookie_domain']    = ""; $config['cookie_path']  = "/";
+
+Lastly, add the following new item to the config file (and edit the
+option if needed)::
+
+	 /* |------------------------------------------------ | URI PROTOCOL |------------------------------------------------ | | This item determines which server global  | should be used to retrieve the URI string.  The  | default setting of "auto" works for most servers. | If your links do not seem to work, try one of  | the other delicious flavors: |  | 'auto'            Default - auto detects | 'path_info'       Uses the PATH_INFO  | 'query_string'    Uses the QUERY_STRING */  $config['uri_protocol'] = "auto";

+##################
+Benchmarking Class
+##################
+
+CodeIgniter has a Benchmarking class that is always active, enabling the
+time difference between any two marked points to be calculated.
+
+.. note:: This class is initialized automatically by the system so there
+	is no need to do it manually.
+
+In addition, the benchmark is always started the moment the framework is
+invoked, and ended by the output class right before sending the final
+view to the browser, enabling a very accurate timing of the entire
+system execution to be shown.
+
+.. contents:: Table of Contents
+
+Using the Benchmark Class
+=========================
+
+The Benchmark class can be used within your
+:doc:`controllers </general/controllers>`,
+:doc:`views </general/views>`, or your :doc:`models </general/models>`.
+The process for usage is this:
+
+#. Mark a start point
+#. Mark an end point
+#. Run the "elapsed time" function to view the results
+
+Here's an example using real code::
+
+	$this->benchmark->mark('code_start');
+	
+	// Some code happens here
+	
+	$this->benchmark->mark('code_end');
+	
+	echo $this->benchmark->elapsed_time('code_start', 'code_end');
+
+.. note:: The words "code_start" and "code_end" are arbitrary. They
+	are simply words used to set two markers. You can use any words you
+	want, and you can set multiple sets of markers. Consider this example::
+
+		$this->benchmark->mark('dog');
+	
+		// Some code happens here
+	
+		$this->benchmark->mark('cat');
+	
+		// More code happens here
+	
+		$this->benchmark->mark('bird');
+	
+		echo $this->benchmark->elapsed_time('dog', 'cat');
+		echo $this->benchmark->elapsed_time('cat', 'bird');
+		echo $this->benchmark->elapsed_time('dog', 'bird');
+
+
+Profiling Your Benchmark Points
+===============================
+
+If you want your benchmark data to be available to the
+:doc:`Profiler </general/profiling>` all of your marked points must
+be set up in pairs, and each mark point name must end with _start and
+_end. Each pair of points must otherwise be named identically. Example::
+
+	 $this->benchmark->mark('my_mark_start');
+	
+	// Some code happens here...
+	
+	$this->benchmark->mark('my_mark_end');
+	
+	$this->benchmark->mark('another_mark_start');
+	
+	// Some more code happens here...
+	
+	$this->benchmark->mark('another_mark_end');
+
+Please read the :doc:`Profiler page </general/profiling>` for more
+information.
+
+Displaying Total Execution Time
+===============================
+
+If you would like to display the total elapsed time from the moment
+CodeIgniter starts to the moment the final output is sent to the
+browser, simply place this in one of your view templates::
+
+	<?php echo $this->benchmark->elapsed_time();?>
+
+You'll notice that it's the same function used in the examples above to
+calculate the time between two point, except you are **not** using any
+parameters. When the parameters are absent, CodeIgniter does not stop
+the benchmark until right before the final output is sent to the
+browser. It doesn't matter where you use the function call, the timer
+will continue to run until the very end.
+
+An alternate way to show your elapsed time in your view files is to use
+this pseudo-variable, if you prefer not to use the pure PHP::
+
+	{elapsed_time}
+
+.. note:: If you want to benchmark anything within your controller
+	functions you must set your own start/end points.
+
+Displaying Memory Consumption
+=============================
+
+If your PHP installation is configured with --enable-memory-limit, you
+can display the amount of memory consumed by the entire system using the
+following code in one of your view file::
+
+	<?php echo $this->benchmark->memory_usage();?>
+
+.. note:: This function can only be used in your view files. The consumption
+	will reflect the total memory used by the entire app.
+
+An alternate way to show your memory usage in your view files is to use
+this pseudo-variable, if you prefer not to use the pure PHP::
+
+	{memory_usage}
+

+Caching Driver
+##############
+
+CodeIgniter features wrappers around some of the most popular forms of
+fast and dynamic caching. All but file-based caching require specific
+server requirements, and a Fatal Exception will be thrown if server
+requirements are not met.
+
+.. contents:: Table of Contents
+
+*************
+Example Usage
+*************
+
+The following example will load the cache driver, specify `APC <#apc>`_
+as the driver to use, and fall back to file-based caching if APC is not
+available in the hosting environment.
+
+::
+
+	$this->load->driver('cache', array('adapter' => 'apc', 'backup' => 'file'));
+	
+	if ( ! $foo = $this->cache->get('foo'))
+	{
+		echo 'Saving to the cache!<br />';
+		$foo = 'foobarbaz!';
+		
+		// Save into the cache for 5 minutes
+		$this->cache->save('foo', $foo, 300);
+	}
+	
+	echo $foo;
+
+******************

+*******
+Drivers
+*******
+
+Alternative PHP Cache (APC) Caching
+===================================
+
+All of the functions listed above can be accessed without passing a
+specific adapter to the driver loader as follows::
+
+	$this->load->driver('cache');
+	$this->cache->apc->save('foo', 'bar', 10);
+
+For more information on APC, please see
+`http://php.net/apc <http://php.net/apc>`_
+
+File-based Caching
+==================
+
+Unlike caching from the Output Class, the driver file-based caching
+allows for pieces of view files to be cached. Use this with care, and
+make sure to benchmark your application, as a point can come where disk
+I/O will negate positive gains by caching.
+
+All of the functions listed above can be accessed without passing a
+specific adapter to the driver loader as follows::
+
+	$this->load->driver('cache');
+	$this->cache->file->save('foo', 'bar', 10);
+
+Memcached Caching
+=================
+
+Multiple Memcached servers can be specified in the memcached.php
+configuration file, located in the application/config/ directory.
+
+All of the functions listed above can be accessed without passing a
+specific adapter to the driver loader as follows::
+
+	$this->load->driver('cache');
+	$this->cache->memcached->save('foo', 'bar', 10);
+
+For more information on Memcached, please see
+`http://php.net/memcached <http://php.net/memcached>`_
+
+Dummy Cache
+===========
+
+This is a caching backend that will always 'miss.' It stores no data,
+but lets you keep your caching code in place in environments that don't
+support your chosen cache.

+#################
+Calendaring Class
+#################
+
+The Calendar class enables you to dynamically create calendars. Your
+calendars can be formatted through the use of a calendar template,
+allowing 100% control over every aspect of its design. In addition, you
+can pass data to your calendar cells.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Calendar class is
+initialized in your controller using the $this->load->library function::
+
+	$this->load->library('calendar');
+
+Once loaded, the Calendar object will be available using::
+
+	$this->calendar
+
+Displaying a Calendar
+=====================
+
+Here is a very simple example showing how you can display a calendar::
+
+	$this->load->library('calendar');
+	echo $this->calendar->generate();
+
+The above code will generate a calendar for the current month/year based
+on your server time. To show a calendar for a specific month and year
+you will pass this information to the calendar generating function::
+
+	$this->load->library('calendar');
+	echo $this->calendar->generate(2006, 6);
+
+The above code will generate a calendar showing the month of June in
+2006. The first parameter specifies the year, the second parameter
+specifies the month.
+
+Passing Data to your Calendar Cells
+===================================
+
+To add data to your calendar cells involves creating an associative
+array in which the keys correspond to the days you wish to populate and
+the array value contains the data. The array is passed to the third
+parameter of the calendar generating function. Consider this example::
+
+	$this->load->library('calendar');
+
+	$data = array(
+		3  => 'http://example.com/news/article/2006/03/',
+		7  => 'http://example.com/news/article/2006/07/',
+		13 => 'http://example.com/news/article/2006/13/',
+		26 => 'http://example.com/news/article/2006/26/'
+	);
+
+	echo $this->calendar->generate(2006, 6, $data);
+
+Using the above example, day numbers 3, 7, 13, and 26 will become links
+pointing to the URLs you've provided.
+
+.. note:: By default it is assumed that your array will contain links.
+	In the section that explains the calendar template below you'll see how
+	you can customize how data passed to your cells is handled so you can
+	pass different types of information.
+
+Setting Display Preferences
+===========================
+
+There are seven preferences you can set to control various aspects of
+the calendar. Preferences are set by passing an array of preferences in
+the second parameter of the loading function. Here is an example::
+
+	$prefs = array (
+		'start_day'	=> 'saturday',
+		'month_type'   => 'long',
+		'day_type'	 => 'short'
+	);
+
+	$this->load->library('calendar', $prefs);
+
+	echo $this->calendar->generate();
+
+The above code would start the calendar on saturday, use the "long"
+month heading, and the "short" day names. More information regarding
+preferences below.
+
++-----------------------+-----------+-----------------------------------------------+-------------------------------------------------------------------+
+| Preference            | Default   | Options                                       |    Description                                                    |

+| **local_time**        | time()    | None                                          | A Unix timestamp corresponding to the current time.               |
++-----------------------+-----------+-----------------------------------------------+-------------------------------------------------------------------+
+| **start_day**         | sunday    | Any week day (sunday, monday, tuesday, etc.)  | Sets the day of the week the calendar should start on.            |
++-----------------------+-----------+-----------------------------------------------+-------------------------------------------------------------------+
+| **month_type**        | long      | long, short                                   | Determines what version of the month name to use in the header.   |
+|                       |           |                                               | long = January, short = Jan.                                      |

+| **day_type**          | abr       | long, short, abr                              | Determines what version of the weekday names to use in            |
+|                       |           |                                               | the column headers.                                               |
+|                       |           |                                               | long = Sunday, short = Sun, abr = Su.                             |
++-----------------------+-----------+-----------------------------------------------+-------------------------------------------------------------------+
+| **show_next_prev**    | FALSE     | TRUE/FALSE (boolean)                          | Determines whether to display links allowing you to toggle        |
+|                       |           |                                               | to next/previous months. See information on this feature below.   |
++-----------------------+-----------+-----------------------------------------------+-------------------------------------------------------------------+
+| **next_prev_url**     | None      | A URL                                         | Sets the basepath used in the next/previous calendar links.       |
++-----------------------+-----------+-----------------------------------------------+-------------------------------------------------------------------+
+
+
+Showing Next/Previous Month Links
+=================================
+
+To allow your calendar to dynamically increment/decrement via the
+next/previous links requires that you set up your calendar code similar
+to this example::
+
+	$prefs = array (
+				   'show_next_prev'  => TRUE,
+				   'next_prev_url'   => 'http://example.com/index.php/calendar/show/'
+				 );
+
+	$this->load->library('calendar', $prefs);
+
+	echo $this->calendar->generate($this->uri->segment(3), $this->uri->segment(4));
+
+You'll notice a few things about the above example:
+
+-  You must set the "show_next_prev" to TRUE.
+-  You must supply the URL to the controller containing your calendar in
+   the "next_prev_url" preference.
+-  You must supply the "year" and "month" to the calendar generating
+   function via the URI segments where they appear (Note: The calendar
+   class automatically adds the year/month to the base URL you
+   provide.).
+
+Creating a Calendar Template
+============================
+
+By creating a calendar template you have 100% control over the design of
+your calendar. Each component of your calendar will be placed within a
+pair of pseudo-variables as shown here::
+
+	$prefs['template'] = '
+
+		{table_open}<table border="0" cellpadding="0" cellspacing="0">{/table_open}
+
+		{heading_row_start}<tr>{/heading_row_start}
+
+		{heading_previous_cell}<th><a href="{previous_url}">&lt;&lt;</a></th>{/heading_previous_cell}
+		{heading_title_cell}<th colspan="{colspan}">{heading}</th>{/heading_title_cell}
+		{heading_next_cell}<th><a href="{next_url}">&gt;&gt;</a></th>{/heading_next_cell}
+
+		{heading_row_end}</tr>{/heading_row_end}
+
+		{week_row_start}<tr>{/week_row_start}
+		{week_day_cell}<td>{week_day}</td>{/week_day_cell}
+		{week_row_end}</tr>{/week_row_end}
+
+		{cal_row_start}<tr>{/cal_row_start}
+		{cal_cell_start}<td>{/cal_cell_start}
+
+		{cal_cell_content}<a href="{content}">{day}</a>{/cal_cell_content}
+		{cal_cell_content_today}<div class="highlight"><a href="{content}">{day}</a></div>{/cal_cell_content_today}
+
+		{cal_cell_no_content}{day}{/cal_cell_no_content}
+		{cal_cell_no_content_today}<div class="highlight">{day}</div>{/cal_cell_no_content_today}
+
+		{cal_cell_blank}&nbsp;{/cal_cell_blank}
+
+		{cal_cell_end}</td>{/cal_cell_end}
+		{cal_row_end}</tr>{/cal_row_end}
+
+		{table_close}</table>{/table_close}
+	';
+
+	$this->load->library('calendar', $prefs);
+
+	echo $this->calendar->generate();

+###################
+Shopping Cart Class
+###################
+
+The Cart Class permits items to be added to a session that stays active
+while a user is browsing your site. These items can be retrieved and
+displayed in a standard "shopping cart" format, allowing the user to
+update the quantity or remove items from the cart.
+
+Please note that the Cart Class ONLY provides the core "cart"
+functionality. It does not provide shipping, credit card authorization,
+or other processing components.
+
+.. contents:: Page Contents
+
+Initializing the Shopping Cart Class
+====================================
+
+.. important:: The Cart class utilizes CodeIgniter's :doc:`Session
+	Class <sessions>` to save the cart information to a database, so
+	before using the Cart class you must set up a database table as
+	indicated in the :doc:`Session Documentation <sessions>`, and set the
+	session preferences in your application/config/config.php file to
+	utilize a database.
+
+To initialize the Shopping Cart Class in your controller constructor,
+use the $this->load->library function::
+
+	$this->load->library('cart');
+
+Once loaded, the Cart object will be available using::
+ 	
+	$this->cart
+
+.. note:: The Cart Class will load and initialize the Session Class
+	automatically, so unless you are using sessions elsewhere in your
+	application, you do not need to load the Session class.
+
+Adding an Item to The Cart
+==========================
+
+To add an item to the shopping cart, simply pass an array with the
+product information to the $this->cart->insert() function, as shown
+below::
+
+	$data = array(
+		'id'		=> 'sku_123ABC',
+		'qty'	=> 1,
+		'price'	=> 39.95,
+		'name'	=> 'T-Shirt',
+		'options'	=> array('Size' => 'L', 'Color' => 'Red')
+	);
+
+	$this->cart->insert($data);
+
+.. important:: The first four array indexes above (id, qty, price, and
+	name) are **required**. If you omit any of them the data will not be
+	saved to the cart. The fifth index (options) is optional. It is intended
+	to be used in cases where your product has options associated with it.
+	Use an array for options, as shown above.
+
+The five reserved indexes are:
+
+-  **id** - Each product in your store must have a unique identifier.
+   Typically this will be an "sku" or other such identifier.
+-  **qty** - The quantity being purchased.
+-  **price** - The price of the item.
+-  **name** - The name of the item.
+-  **options** - Any additional attributes that are needed to identify
+   the product. These must be passed via an array.
+
+In addition to the five indexes above, there are two reserved words:
+rowid and subtotal. These are used internally by the Cart class, so
+please do NOT use those words as index names when inserting data into
+the cart.
+
+Your array may contain additional data. Anything you include in your
+array will be stored in the session. However, it is best to standardize
+your data among all your products in order to make displaying the
+information in a table easier.
+
+The insert() method will return the $rowid if you successfully insert a
+single item.
+
+Adding Multiple Items to The Cart
+=================================
+
+By using a multi-dimensional array, as shown below, it is possible to
+add multiple products to the cart in one action. This is useful in cases
+where you wish to allow people to select from among several items on the
+same page.
+
+::
+
+	$data = array(
+		 array(
+			'id'	  => 'sku_123ABC',
+			'qty'	 => 1,
+			'price'   => 39.95,
+			'name'	=> 'T-Shirt',
+			'options' => array('Size' => 'L', 'Color' => 'Red')
+		),
+		 array(
+			'id'	  => 'sku_567ZYX',
+			'qty'	 => 1,
+			'price'   => 9.95,
+			'name'	=> 'Coffee Mug'
+		),
+		 array(
+			'id'	  => 'sku_965QRS',
+			'qty'	 => 1,
+			'price'   => 29.95,
+			'name'	=> 'Shot Glass'
+		)
+	);
+
+	$this->cart->insert($data);
+
+Displaying the Cart
+===================
+
+To display the cart you will create a :doc:`view
+file </general/views>` with code similar to the one shown below.
+
+Please note that this example uses the :doc:`form
+helper </helpers/form_helper>`.
+
+::
+
+	<?php echo form_open('path/to/controller/update/function'); ?>
+
+	<table cellpadding="6" cellspacing="1" style="width:100%" border="0">
+
+	<tr>
+	  <th>QTY</th>
+	  <th>Item Description</th>
+	  <th style="text-align:right">Item Price</th>
+	  <th style="text-align:right">Sub-Total</th>
+	</tr>
+
+	<?php $i = 1; ?>
+
+	<?php foreach ($this->cart->contents() as $items): ?>
+
+		<?php echo form_hidden($i.'[rowid]', $items['rowid']); ?>
+
+		<tr>
+		  <td><?php echo form_input(array('name' => $i.'[qty]', 'value' => $items['qty'], 'maxlength' => '3', 'size' => '5')); ?></td>
+		  <td>
+			<?php echo $items['name']; ?>
+
+				<?php if ($this->cart->has_options($items['rowid']) == TRUE): ?>
+
+					<p>
+						<?php foreach ($this->cart->product_options($items['rowid']) as $option_name => $option_value): ?>
+
+							<strong><?php echo $option_name; ?>:</strong> <?php echo $option_value; ?><br />
+
+						<?php endforeach; ?>
+					</p>
+
+				<?php endif; ?>
+
+		  </td>
+		  <td style="text-align:right"><?php echo $this->cart->format_number($items['price']); ?></td>
+		  <td style="text-align:right">$<?php echo $this->cart->format_number($items['subtotal']); ?></td>
+		</tr>
+
+	<?php $i++; ?>
+
+	<?php endforeach; ?>
+
+	<tr>
+	  <td colspan="2"> </td>
+	  <td class="right"><strong>Total</strong></td>
+	  <td class="right">$<?php echo $this->cart->format_number($this->cart->total()); ?></td>
+	</tr>
+
+	</table>
+
+	<p><?php echo form_submit('', 'Update your Cart'); ?></p>
+	
+Updating The Cart
+=================
+
+To update the information in your cart, you must pass an array
+containing the Row ID and quantity to the $this->cart->update()
+function:
+
+.. note:: If the quantity is set to zero, the item will be removed from
+	the cart.
+
+::
+
+	$data = array(
+		'rowid' => 'b99ccdf16028f015540f341130b6d8ec',
+		'qty'   => 3
+	);
+
+	$this->cart->update($data); 
+
+	// Or a multi-dimensional array
+
+	$data = array(
+		array(
+		   'rowid'   => 'b99ccdf16028f015540f341130b6d8ec',
+		   'qty'     => 3
+		),
+		array(
+		   'rowid'   => 'xw82g9q3r495893iajdh473990rikw23',
+		   'qty'     => 4
+		),
+		array(
+		   'rowid'   => 'fh4kdkkkaoe30njgoe92rkdkkobec333',
+		   'qty'     => 2
+		)
+	);
+
+	$this->cart->update($data); 
+
+What is a Row ID?
+*****************
+
+The row ID is a unique identifier that is
+generated by the cart code when an item is added to the cart. The reason
+a unique ID is created is so that identical products with different
+options can be managed by the cart.
+
+For example, let's say someone buys two identical t-shirts (same product
+ID), but in different sizes. The product ID (and other attributes) will
+be identical for both sizes because it's the same shirt. The only
+difference will be the size. The cart must therefore have a means of
+identifying this difference so that the two sizes of shirts can be
+managed independently. It does so by creating a unique "row ID" based on
+the product ID and any options associated with it.
+
+In nearly all cases, updating the cart will be something the user does
+via the "view cart" page, so as a developer, it is unlikely that you
+will ever have to concern yourself with the "row ID", other then making
+sure your "view cart" page contains this information in a hidden form
+field, and making sure it gets passed to the update function when the
+update form is submitted. Please examine the construction of the "view
+cart" page above for more information.

+############
+Config Class
+############
+
+The Config class provides a means to retrieve configuration preferences.
+These preferences can come from the default config file
+(application/config/config.php) or from your own custom config files.
+
+.. note:: This class is initialized automatically by the system so there
+	is no need to do it manually.
+
+.. contents:: Page Contents
+
+Anatomy of a Config File
+========================
+
+By default, CodeIgniter has one primary config file, located at
+application/config/config.php. If you open the file using your text
+editor you'll see that config items are stored in an array called
+$config.
+
+You can add your own config items to this file, or if you prefer to keep
+your configuration items separate (assuming you even need config items),
+simply create your own file and save it in config folder.
+
+.. note:: If you do create your own config files use the same format as
+	the primary one, storing your items in an array called $config.
+	CodeIgniter will intelligently manage these files so there will be no
+	conflict even though the array has the same name (assuming an array
+	index is not named the same as another).
+
+Loading a Config File
+=====================
+
+.. note::
+	CodeIgniter automatically loads the primary config file
+	(application/config/config.php), so you will only need to load a config
+	file if you have created your own.
+
+There are two ways to load a config file:
+
+Manual Loading
+**************
+
+To load one of your custom config files you will use the following
+function within the :doc:`controller </general/controllers>` that
+needs it::
+
+	$this->config->load('filename');
+
+Where filename is the name of your config file, without the .php file
+extension.
+
+If you need to load multiple config files normally they will be
+merged into one master config array. Name collisions can occur,
+however, if you have identically named array indexes in different
+config files. To avoid collisions you can set the second parameter to
+TRUE and each config file will be stored in an array index
+corresponding to the name of the config file. Example::
+
+	// Stored in an array with this prototype: $this->config['blog_settings'] = $config
+	$this->config->load('blog_settings', TRUE);
+
+Please see the section entitled Fetching Config Items below to learn
+how to retrieve config items set this way.
+
+The third parameter allows you to suppress errors in the event that a
+config file does not exist::
+
+	$this->config->load('blog_settings', FALSE, TRUE);
+
+Auto-loading
+************
+
+If you find that you need a particular config file globally, you can
+have it loaded automatically by the system. To do this, open the
+**autoload.php** file, located at application/config/autoload.php,
+and add your config file as indicated in the file.
+
+
+Fetching Config Items
+=====================
+
+To retrieve an item from your config file, use the following function::
+
+	$this->config->item('item name');
+
+Where item name is the $config array index you want to retrieve. For
+example, to fetch your language choice you'll do this::
+
+	$lang = $this->config->item('language');
+
+The function returns FALSE (boolean) if the item you are trying to fetch
+does not exist.
+
+If you are using the second parameter of the $this->config->load
+function in order to assign your config items to a specific index you
+can retrieve it by specifying the index name in the second parameter of
+the $this->config->item() function. Example::
+
+	// Loads a config file named blog_settings.php and assigns it to an index named "blog_settings"
+	$this->config->load('blog_settings', TRUE);
+
+	// Retrieve a config item named site_name contained within the blog_settings array
+	$site_name = $this->config->item('site_name', 'blog_settings');
+
+	// An alternate way to specify the same item:
+	$blog_config = $this->config->item('blog_settings');
+	$site_name = $blog_config['site_name'];
+
+Setting a Config Item
+=====================
+
+If you would like to dynamically set a config item or change an existing
+one, you can do so using::
+
+	$this->config->set_item('item_name', 'item_value');
+
+Where item_name is the $config array index you want to change, and
+item_value is its value.
+
+.. _config-environments:
+
+Environments
+============
+
+You may load different configuration files depending on the current
+environment. The ENVIRONMENT constant is defined in index.php, and is
+described in detail in the :doc:`Handling
+Environments </general/environments>` section.
+
+To create an environment-specific configuration file, create or copy a
+configuration file in application/config/{ENVIRONMENT}/{FILENAME}.php
+
+For example, to create a production-only config.php, you would:
+
+#. Create the directory application/config/production/
+#. Copy your existing config.php into the above directory
+#. Edit application/config/production/config.php so it contains your
+   production settings
+
+When you set the ENVIRONMENT constant to 'production', the settings for
+your new production-only config.php will be loaded.
+
+You can place the following configuration files in environment-specific
+folders:
+
+-  Default CodeIgniter configuration files
+-  Your own custom configuration files
+
+.. note::
+	CodeIgniter always tries to load the configuration files for
+	the current environment first. If the file does not exist, the global
+	config file (i.e., the one in application/config/) is loaded. This means
+	you are not obligated to place **all** of your configuration files in an
+	environment folder − only the files that change per environment.
+
+Helper Functions
+================
+
+The config class has the following helper functions:
+
+$this->config->site_url();
+***************************
+
+This function retrieves the URL to your site, along with the "index"
+value you've specified in the config file.
+
+$this->config->base_url();
+***************************
+
+This function retrieves the URL to your site, plus an optional path such
+as to a stylesheet or image.
+
+The two functions above are normally accessed via the corresponding
+functions in the :doc:`URL Helper </helpers/url_helper>`.
+
+$this->config->system_url();
+*****************************
+
+This function retrieves the URL to your system folder.

+Sending Email
+=============
+
+Sending email is not only simple, but you can configure it on the fly or
+set your preferences in a config file.
+
+Here is a basic example demonstrating how you might send email. Note:
+This example assumes you are sending the email from one of your
+:doc:`controllers <../general/controllers>`.
+
+::
+
+	$this->load->library('email');  $this->email->from('your@example.com', 'Your Name'); $this->email->to('someone@example.com');  $this->email->cc('another@another-example.com');  $this->email->bcc('them@their-example.com');   $this->email->subject('Email Test'); $this->email->message('Testing the email class.');    $this->email->send();  echo $this->email->print_debugger();
+
+Setting Email Preferences
+=========================
+
+There are 17 different preferences available to tailor how your email
+messages are sent. You can either set them manually as described here,
+or automatically via preferences stored in your config file, described
+below:
+
+Preferences are set by passing an array of preference values to the
+email initialize function. Here is an example of how you might set some
+preferences::
+
+	$config['protocol'] = 'sendmail'; $config['mailpath'] = '/usr/sbin/sendmail'; $config['charset'] = 'iso-8859-1'; $config['wordwrap'] = TRUE;  $this->email->initialize($config);
+
+.. note:: Most of the preferences have default values that will be used
+	if you do not set them.
+
+Setting Email Preferences in a Config File
+------------------------------------------
+
+If you prefer not to set preferences using the above method, you can
+instead put them into a config file. Simply create a new file called the
+email.php, add the $config array in that file. Then save the file at
+config/email.php and it will be used automatically. You will NOT need to
+use the $this->email->initialize() function if you save your preferences
+in a config file.
+

+Email Function Reference
+========================
+
+$this->email->from()
+--------------------
+
+Sets the email address and name of the person sending the email::
+
+	$this->email->from('you@example.com', 'Your Name');
+
+$this->email->reply_to()
+-------------------------
+
+Sets the reply-to address. If the information is not provided the
+information in the "from" function is used. Example::
+
+	$this->email->reply_to('you@example.com', 'Your Name');
+
+$this->email->to()
+------------------
+
+Sets the email address(s) of the recipient(s). Can be a single email, a
+comma-delimited list or an array::
+
+	$this->email->to('someone@example.com');
+
+::
+
+	$this->email->to('one@example.com, two@example.com, three@example.com');
+
+::
+
+	$list = array('one@example.com', 'two@example.com', 'three@example.com');  $this->email->to($list);
+
+$this->email->cc()
+------------------
+
+Sets the CC email address(s). Just like the "to", can be a single email,
+a comma-delimited list or an array.
+
+$this->email->bcc()
+-------------------
+
+Sets the BCC email address(s). Just like the "to", can be a single
+email, a comma-delimited list or an array.
+
+$this->email->subject()
+-----------------------
+
+Sets the email subject::
+
+	$this->email->subject('This is my subject');
+
+$this->email->message()
+-----------------------
+
+Sets the email message body::
+
+	$this->email->message('This is my message');
+
+$this->email->set_alt_message()
+---------------------------------
+
+Sets the alternative email message body::
+
+	$this->email->set_alt_message('This is the alternative message');
+
+This is an optional message string which can be used if you send HTML
+formatted email. It lets you specify an alternative message with no HTML
+formatting which is added to the header string for people who do not
+accept HTML email. If you do not set your own message CodeIgniter will
+extract the message from your HTML email and strip the tags.
+
+$this->email->clear()
+---------------------
+
+Initializes all the email variables to an empty state. This function is
+intended for use if you run the email sending function in a loop,
+permitting the data to be reset between cycles.
+
+::
+
+	foreach ($list as $name => $address) {     $this->email->clear();      $this->email->to($address);     $this->email->from('your@example.com');     $this->email->subject('Here is your info '.$name);     $this->email->message('Hi '.$name.' Here is the info you requested.');     $this->email->send(); }
+
+If you set the parameter to TRUE any attachments will be cleared as
+well::
+
+	$this->email->clear(TRUE);
+
+$this->email->send()
+--------------------
+
+The Email sending function. Returns boolean TRUE or FALSE based on
+success or failure, enabling it to be used conditionally::
+
+	if ( ! $this->email->send()) {     // Generate error }
+
+$this->email->attach()
+----------------------
+
+Enables you to send an attachment. Put the file path/name in the first
+parameter. Note: Use a file path, not a URL. For multiple attachments
+use the function multiple times. For example::
+
+	$this->email->attach('/path/to/photo1.jpg'); $this->email->attach('/path/to/photo2.jpg'); $this->email->attach('/path/to/photo3.jpg');  $this->email->send();
+
+$this->email->print_debugger()
+-------------------------------
+
+Returns a string containing any server messages, the email headers, and
+the email messsage. Useful for debugging.
+
+Overriding Word Wrapping
+========================
+
+If you have word wrapping enabled (recommended to comply with RFC 822)
+and you have a very long link in your email it can get wrapped too,
+causing it to become un-clickable by the person receiving it.
+CodeIgniter lets you manually override word wrapping within part of your
+message like this::
+
+	The text of your email that gets wrapped normally.  {unwrap}http://example.com/a_long_link_that_should_not_be_wrapped.html{/unwrap}  More text that will be wrapped normally.
+
+Place the item you do not want word-wrapped between: {unwrap} {/unwrap}

+################
+Encryption Class
+################
+
+The Encryption Class provides two-way data encryption. It uses a scheme
+that either compiles the message using a randomly hashed bitwise XOR
+encoding scheme, or is encrypted using the Mcrypt library. If Mcrypt is
+not available on your server the encoded message will still provide a
+reasonable degree of security for encrypted sessions or other such
+"light" purposes. If Mcrypt is available, you'll be provided with a high
+degree of security appropriate for storage.
+
+Setting your Key
+================
+
+A *key* is a piece of information that controls the cryptographic
+process and permits an encrypted string to be decoded. In fact, the key
+you chose will provide the **only** means to decode data that was
+encrypted with that key, so not only must you choose the key carefully,
+you must never change it if you intend use it for persistent data.
+
+It goes without saying that you should guard your key carefully. Should
+someone gain access to your key, the data will be easily decoded. If
+your server is not totally under your control it's impossible to ensure
+key security so you may want to think carefully before using it for
+anything that requires high security, like storing credit card numbers.
+
+To take maximum advantage of the encryption algorithm, your key should
+be 32 characters in length (128 bits). The key should be as random a
+string as you can concoct, with numbers and uppercase and lowercase
+letters. Your key should **not** be a simple text string. In order to be
+cryptographically secure it needs to be as random as possible.
+
+Your key can be either stored in your application/config/config.php, or
+you can design your own storage mechanism and pass the key dynamically
+when encoding/decoding.
+
+To save your key to your application/config/config.php, open the file
+and set::
+
+	$config['encryption_key'] = "YOUR KEY";
+
+Message Length
+==============
+
+It's important for you to know that the encoded messages the encryption
+function generates will be approximately 2.6 times longer than the
+original message. For example, if you encrypt the string "my super
+secret data", which is 21 characters in length, you'll end up with an
+encoded string that is roughly 55 characters (we say "roughly" because
+the encoded string length increments in 64 bit clusters, so it's not
+exactly linear). Keep this information in mind when selecting your data
+storage mechanism. Cookies, for example, can only hold 4K of
+information.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Encryption class is
+initialized in your controller using the $this->load->library function::
+
+	$this->load->library('encrypt');
+
+Once loaded, the Encrypt library object will be available using:
+$this->encrypt
+
+$this->encrypt->encode()
+========================
+
+Performs the data encryption and returns it as a string. Example::
+
+	 $msg = 'My secret message';  $encrypted_string = $this->encrypt->encode($msg);
+
+You can optionally pass your encryption key via the second parameter if
+you don't want to use the one in your config file::
+
+	 $msg = 'My secret message'; $key = 'super-secret-key';  $encrypted_string = $this->encrypt->encode($msg, $key);
+
+$this->encrypt->decode()
+========================
+
+Decrypts an encoded string. Example::
+
+	 $encrypted_string = 'APANtByIGI1BpVXZTJgcsAG8GZl8pdwwa84';  $plaintext_string = $this->encrypt->decode($encrypted_string);
+
+You can optionally pass your encryption key via the second parameter if
+you don't want to use the one in your config file::
+
+	 $msg = 'My secret message'; $key = 'super-secret-key';  $encrypted_string = $this->encrypt->decode($msg, $key);
+
+$this->encrypt->set_cipher();
+==============================
+
+Permits you to set an Mcrypt cipher. By default it uses
+MCRYPT_RIJNDAEL_256. Example::
+
+	$this->encrypt->set_cipher(MCRYPT_BLOWFISH);
+
+Please visit php.net for a list of `available
+ciphers <http://php.net/mcrypt>`_.
+
+If you'd like to manually test whether your server supports Mcrypt you
+can use::
+
+	echo ( ! function_exists('mcrypt_encrypt')) ? 'Nope' : 'Yup';
+
+$this->encrypt->set_mode();
+============================
+
+Permits you to set an Mcrypt mode. By default it uses MCRYPT_MODE_CBC.
+Example::
+
+	$this->encrypt->set_mode(MCRYPT_MODE_CFB);
+
+Please visit php.net for a list of `available
+modes <http://php.net/mcrypt>`_.
+
+$this->encrypt->sha1();
+=======================
+
+SHA1 encoding function. Provide a string and it will return a 160 bit
+one way hash. Note: SHA1, just like MD5 is non-decodable. Example::
+
+	$hash = $this->encrypt->sha1('Some string');
+
+Many PHP installations have SHA1 support by default so if all you need
+is to encode a hash it's simpler to use the native function::
+
+	$hash = sha1('Some string');
+
+If your server does not support SHA1 you can use the provided function.
+
+$this->encrypt->encode_from_legacy($orig_data, $legacy_mode =
+MCRYPT_MODE_ECB, $key = '');
+==============================
+
+Enables you to re-encode data that was originally encrypted with
+CodeIgniter 1.x to be compatible with the Encryption library in
+CodeIgniter 2.x. It is only necessary to use this method if you have
+encrypted data stored permanently such as in a file or database and are
+on a server that supports Mcrypt. "Light" use encryption such as
+encrypted session data or transitory encrypted flashdata require no
+intervention on your part. However, existing encrypted Sessions will be
+destroyed since data encrypted prior to 2.x will not be decoded.
+
+**Why only a method to re-encode the data instead of maintaining legacy
+methods for both encoding and decoding?** The algorithms in the
+Encryption library have improved in CodeIgniter 2.x both for performance
+and security, and we do not wish to encourage continued use of the older
+methods. You can of course extend the Encryption library if you wish and
+replace the new methods with the old and retain seamless compatibility
+with CodeIgniter 1.x encrypted data, but this a decision that a
+developer should make cautiously and deliberately, if at all.
+
+::
+
+	$new_data = $this->encrypt->encode_from_legacy($old_encrypted_string);
+
+Parameter
+Default
+Description
+**$orig_data**
+n/a
+The original encrypted data from CodeIgniter 1.x's Encryption library
+**$legacy_mode**
+MCRYPT_MODE_ECB
+The Mcrypt mode that was used to generate the original encrypted data.
+CodeIgniter 1.x's default was MCRYPT_MODE_ECB, and it will assume that
+to be the case unless overridden by this parameter.
+**$key**
+n/a
+The encryption key. This it typically specified in your config file as
+outlined above.

+File Uploading Class
+####################
+
+CodeIgniter's File Uploading Class permits files to be uploaded. You can
+set various preferences, restricting the type and size of the files.
+
+***********
+The Process
+***********
+
+Uploading a file involves the following general process:
+
+-  An upload form is displayed, allowing a user to select a file and
+   upload it.
+-  When the form is submitted, the file is uploaded to the destination
+   you specify.
+-  Along the way, the file is validated to make sure it is allowed to be
+   uploaded based on the preferences you set.
+-  Once uploaded, the user will be shown a success message.
+
+To demonstrate this process here is brief tutorial. Afterward you'll
+find reference information.
+
+Creating the Upload Form
+========================
+
+Using a text editor, create a form called upload_form.php. In it, place
+this code and save it to your applications/views/ folder:
+
+<html> <head> <title>Upload Form</title> </head> <body> <?php echo
+$error;?> <?php echo form_open_multipart('upload/do_upload');?>
+<input type="file" name="userfile" size="20" /> <br /><br /> <input
+type="submit" value="upload" /> </form> </body> </html>
+You'll notice we are using a form helper to create the opening form tag.
+File uploads require a multipart form, so the helper creates the proper
+syntax for you. You'll also notice we have an $error variable. This is
+so we can show error messages in the event the user does something
+wrong.
+
+The Success Page
+================
+
+Using a text editor, create a form called upload_success.php. In it,
+place this code and save it to your applications/views/ folder:
+
+<html> <head> <title>Upload Form</title> </head> <body> <h3>Your file
+was successfully uploaded!</h3> <ul> <?php foreach ($upload_data as
+$item => $value):?> <li><?php echo $item;?>: <?php echo $value;?></li>
+<?php endforeach; ?> </ul> <p><?php echo anchor('upload', 'Upload
+Another File!'); ?></p> </body> </html>
+The Controller
+==============
+
+Using a text editor, create a controller called upload.php. In it, place
+this code and save it to your applications/controllers/ folder:
+
+<?php class Upload extends CI_Controller { function \__construct() {
+parent::\__construct(); $this->load->helper(array('form', 'url')); }
+function index() { $this->load->view('upload_form', array('error' => '
+' )); } function do_upload() { $config['upload_path'] = './uploads/';
+$config['allowed_types'] = 'gif\|jpg\|png'; $config['max_size'] =
+'100'; $config['max_width'] = '1024'; $config['max_height'] = '768';
+$this->load->library('upload', $config); if ( !
+$this->upload->do_upload()) { $error = array('error' =>
+$this->upload->display_errors()); $this->load->view('upload_form',
+$error); } else { $data = array('upload_data' =>
+$this->upload->data()); $this->load->view('upload_success', $data); } }
+} ?>
+
+The Upload Folder
+=================
+
+You'll need a destination folder for your uploaded images. Create a
+folder at the root of your CodeIgniter installation called uploads and
+set its file permissions to 777.
+
+Try it!
+=======
+
+To try your form, visit your site using a URL similar to this one::
+
+	example.com/index.php/upload/
+
+You should see an upload form. Try uploading an image file (either a
+jpg, gif, or png). If the path in your controller is correct it should
+work.
+
+***************
+Reference Guide
+***************
+
+Initializing the Upload Class
+=============================
+
+Like most other classes in CodeIgniter, the Upload class is initialized
+in your controller using the $this->load->library function::
+
+	$this->load->library('upload');
+
+Once the Upload class is loaded, the object will be available using:
+$this->upload
+
+Setting Preferences
+===================
+
+Similar to other libraries, you'll control what is allowed to be upload
+based on your preferences. In the controller you built above you set the
+following preferences::
+
+	$config['upload_path'] = './uploads/'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '100'; $config['max_width']  = '1024'; $config['max_height']  = '768';  $this->load->library('upload', $config);  // Alternately you can set preferences by calling the initialize function.  Useful if you auto-load the class: $this->upload->initialize($config);
+
+The above preferences should be fairly self-explanatory. Below is a
+table describing all available preferences.
+
+Preferences
+===========
+
+The following preferences are available. The default value indicates
+what will be used if you do not specify that preference.
+
+Preference
+Default Value
+Options
+Description
+**upload_path**
+None
+None
+The path to the folder where the upload should be placed. The folder
+must be writable and the path can be absolute or relative.
+**allowed_types**
+None
+None
+The mime types corresponding to the types of files you allow to be
+uploaded. Usually the file extension can be used as the mime type.
+Separate multiple types with a pipe.
+**file_name**
+None
+Desired file name
+If set CodeIgniter will rename the uploaded file to this name. The
+extension provided in the file name must also be an allowed file type.
+
+**overwrite**
+FALSE
+TRUE/FALSE (boolean)
+If set to true, if a file with the same name as the one you are
+uploading exists, it will be overwritten. If set to false, a number will
+be appended to the filename if another with the same name exists.
+**max_size**
+0
+None
+The maximum size (in kilobytes) that the file can be. Set to zero for no
+limit. Note: Most PHP installations have their own limit, as specified
+in the php.ini file. Usually 2 MB (or 2048 KB) by default.
+**max_width**
+0
+None
+The maximum width (in pixels) that the file can be. Set to zero for no
+limit.
+**max_height**
+0
+None
+The maximum height (in pixels) that the file can be. Set to zero for no
+limit.
+**max_filename**
+0
+None
+The maximum length that a file name can be. Set to zero for no limit.
+**max_filename_increment**
+100
+None
+When overwrite is set to FALSE, use this to set the maximum filename
+increment for CodeIgniter to append to the filename.
+**encrypt_name**
+FALSE
+TRUE/FALSE (boolean)
+If set to TRUE the file name will be converted to a random encrypted
+string. This can be useful if you would like the file saved with a name
+that can not be discerned by the person uploading it.
+**remove_spaces**
+TRUE
+TRUE/FALSE (boolean)
+If set to TRUE, any spaces in the file name will be converted to
+underscores. This is recommended.
+
+Setting preferences in a config file
+====================================
+
+If you prefer not to set preferences using the above method, you can
+instead put them into a config file. Simply create a new file called the
+upload.php, add the $config array in that file. Then save the file in:
+config/upload.php and it will be used automatically. You will NOT need
+to use the $this->upload->initialize function if you save your
+preferences in a config file.
+
+******************
+Function Reference
+******************
+
+The following functions are available
+
+$this->upload->do_upload()
+===========================
+
+Performs the upload based on the preferences you've set. Note: By
+default the upload routine expects the file to come from a form field
+called userfile, and the form must be a "multipart type::
+
+	<form method="post" action="some_action" enctype="multipart/form-data" />
+
+If you would like to set your own field name simply pass its value to
+the do_upload function::
+
+	 $field_name = "some_field_name"; $this->upload->do_upload($field_name)
+
+$this->upload->display_errors()
+================================
+
+Retrieves any error messages if the do_upload() function returned
+false. The function does not echo automatically, it returns the data so
+you can assign it however you need.
+
+Formatting Errors
+*****************
+
+By default the above function wraps any errors within <p> tags. You can
+set your own delimiters like this::
+
+	$this->upload->display_errors('<p>', '</p>');
+
+$this->upload->data()
+=====================
+
+This is a helper function that returns an array containing all of the
+data related to the file you uploaded. Here is the array prototype::
+
+	Array (     [file_name]    => mypic.jpg     [file_type]    => image/jpeg     [file_path]    => /path/to/your/upload/     [full_path]    => /path/to/your/upload/jpg.jpg     [raw_name]     => mypic     [orig_name]    => mypic.jpg     [client_name]  => mypic.jpg     [file_ext]     => .jpg     [file_size]    => 22.2     [is_image]     => 1     [image_width]  => 800     [image_height] => 600     [image_type]   => jpeg     [image_size_str] => width="800" height="200" )
+
+Explanation
+***********
+
+Here is an explanation of the above array items.
+
+Item
+Description
+**file_name**
+The name of the file that was uploaded including the file extension.
+**file_type**
+The file's Mime type
+**file_path**

+********
+Overview
+********
+
+Before explaining CodeIgniter's approach to data validation, let's
+describe the ideal scenario:
+
+#. A form is displayed.
+#. You fill it in and submit it.
+#. If you submitted something invalid, or perhaps missed a required
+   item, the form is redisplayed containing your data along with an
+   error message describing the problem.
+#. This process continues until you have submitted a valid form.
+
+On the receiving end, the script must:
+
+#. Check for required data.
+#. Verify that the data is of the correct type, and meets the correct
+   criteria. For example, if a username is submitted it must be
+   validated to contain only permitted characters. It must be of a
+   minimum length, and not exceed a maximum length. The username can't
+   be someone else's existing username, or perhaps even a reserved word.
+   Etc.
+#. Sanitize the data for security.
+#. Pre-format the data if needed (Does the data need to be trimmed? HTML
+   encoded? Etc.)
+#. Prep the data for insertion in the database.
+
+Although there is nothing terribly complex about the above process, it
+usually requires a significant amount of code, and to display error
+messages, various control structures are usually placed within the form
+HTML. Form validation, while simple to create, is generally very messy
+and tedious to implement.
+
+************************
+Form Validation Tutorial
+************************
+
+What follows is a "hands on" tutorial for implementing CodeIgniters Form
+Validation.
+
+In order to implement form validation you'll need three things:
+
+#. A :doc:`View <../general/views>` file containing a form.
+#. A View file containing a "success" message to be displayed upon
+   successful submission.
+#. A :doc:`controller <../general/controllers>` function to receive and
+   process the submitted data.
+
+Let's create those three things, using a member sign-up form as the
+example.
+
+The Form
+========
+
+Using a text editor, create a form called myform.php. In it, place this
+code and save it to your applications/views/ folder:
+
+<html> <head> <title>My Form</title> </head> <body> <?php echo
+validation_errors(); ?> <?php echo form_open('form'); ?>
+<h5>Username</h5> <input type="text" name="username" value="" size="50"
+/> <h5>Password</h5> <input type="text" name="password" value=""
+size="50" /> <h5>Password Confirm</h5> <input type="text"
+name="passconf" value="" size="50" /> <h5>Email Address</h5> <input
+type="text" name="email" value="" size="50" /> <div><input type="submit"
+value="Submit" /></div> </form> </body> </html>
+
+The Success Page
+================
+
+Using a text editor, create a form called formsuccess.php. In it, place
+this code and save it to your applications/views/ folder:
+
+<html> <head> <title>My Form</title> </head> <body> <h3>Your form was
+successfully submitted!</h3> <p><?php echo anchor('form', 'Try it
+again!'); ?></p> </body> </html>
+
+The Controller
+==============
+
+Using a text editor, create a controller called form.php. In it, place
+this code and save it to your applications/controllers/ folder:
+
+<?php class Form extends CI_Controller { function index() {
+$this->load->helper(array('form', 'url'));
+$this->load->library('form_validation'); if
+($this->form_validation->run() == FALSE) { $this->load->view('myform');
+} else { $this->load->view('formsuccess'); } } } ?>
+
+Try it!
+=======
+
+To try your form, visit your site using a URL similar to this one::
+
+	example.com/index.php/form/
+
+If you submit the form you should simply see the form reload. That's
+because you haven't set up any validation rules yet.
+
+**Since you haven't told the Form Validation class to validate anything
+yet, it returns FALSE (boolean false) by default. The run() function
+only returns TRUE if it has successfully applied your rules without any
+of them failing.**
+
+Explanation
+===========
+
+You'll notice several things about the above pages:
+
+The form (myform.php) is a standard web form with a couple exceptions:
+
+#. It uses a form helper to create the form opening. Technically, this
+   isn't necessary. You could create the form using standard HTML.
+   However, the benefit of using the helper is that it generates the
+   action URL for you, based on the URL in your config file. This makes
+   your application more portable in the event your URLs change.
+#. At the top of the form you'll notice the following function call:
+   ::
+
+	<?php echo validation_errors(); ?>
+
+   This function will return any error messages sent back by the
+   validator. If there are no messages it returns an empty string.
+
+The controller (form.php) has one function: index(). This function
+initializes the validation class and loads the form helper and URL
+helper used by your view files. It also runs the validation routine.
+Based on whether the validation was successful it either presents the
+form or the success page.
+
+Setting Validation Rules
+========================
+
+CodeIgniter lets you set as many validation rules as you need for a
+given field, cascading them in order, and it even lets you prep and
+pre-process the field data at the same time. To set validation rules you
+will use the set_rules() function::
+
+	$this->form_validation->set_rules();
+
+The above function takes **three** parameters as input:
+
+#. The field name - the exact name you've given the form field.
+#. A "human" name for this field, which will be inserted into the error
+   message. For example, if your field is named "user" you might give it
+   a human name of "Username".
+#. The validation rules for this form field.
+
+.. note:: If you would like the field
+	name to be stored in a language file, please see `Translating Field
+	Names <#translatingfn>`_.
+
+Here is an example. In your controller (form.php), add this code just
+below the validation initialization function::
+
+	 $this->form_validation->set_rules('username', 'Username', 'required'); $this->form_validation->set_rules('password', 'Password', 'required'); $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required'); $this->form_validation->set_rules('email', 'Email', 'required');
+
+Your controller should now look like this:
+
+<?php class Form extends CI_Controller { function index() {
+$this->load->helper(array('form', 'url'));
+$this->load->library('form_validation');
+$this->form_validation->set_rules('username', 'Username', 'required');
+$this->form_validation->set_rules('password', 'Password', 'required');
+$this->form_validation->set_rules('passconf', 'Password Confirmation',
+'required'); $this->form_validation->set_rules('email', 'Email',
+'required'); if ($this->form_validation->run() == FALSE) {
+$this->load->view('myform'); } else { $this->load->view('formsuccess');
+} } } ?>
+
+Now submit the form with the fields blank and you should see the error
+messages. If you submit the form with all the fields populated you'll
+see your success page.
+
+.. note:: The form fields are not yet being re-populated with the data
+	when there is an error. We'll get to that shortly.
+
+Setting Rules Using an Array
+============================
+
+Before moving on it should be noted that the rule setting function can
+be passed an array if you prefer to set all your rules in one action. If
+you use this approach you must name your array keys as indicated::
+
+	 $config = array(                array(                      'field'   => 'username',                       'label'   => 'Username',                       'rules'   => 'required'                   ),                array(                      'field'   => 'password',                       'label'   => 'Password',                       'rules'   => 'required'                   ),                array(                      'field'   => 'passconf',                       'label'   => 'Password Confirmation',                       'rules'   => 'required'                   ),                   array(                      'field'   => 'email',                       'label'   => 'Email',                       'rules'   => 'required'                   )             );  $this->form_validation->set_rules($config);
+
+Cascading Rules
+===============
+
+CodeIgniter lets you pipe multiple rules together. Let's try it. Change
+your rules in the third parameter of rule setting function, like this::
+
+	 $this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[12]|is_unique[users.username]'); $this->form_validation->set_rules('password', 'Password', 'required|matches[passconf]'); $this->form_validation->set_rules('passconf', 'Password Confirmation', 'required'); $this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[users.email]');
+
+The above code sets the following rules:
+
+#. The username field be no shorter than 5 characters and no longer than
+   12.
+#. The password field must match the password confirmation field.
+#. The email field must contain a valid email address.
+
+Give it a try! Submit your form without the proper data and you'll see
+new error messages that correspond to your new rules. There are numerous
+rules available which you can read about in the validation reference.
+
+Prepping Data
+=============
+
+In addition to the validation functions like the ones we used above, you
+can also prep your data in various ways. For example, you can set up
+rules like this::
+
+	 $this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[5]|max_length[12]|xss_clean'); $this->form_validation->set_rules('password', 'Password', 'trim|required|matches[passconf]|md5'); $this->form_validation->set_rules('passconf', 'Password Confirmation', 'trim|required'); $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');
+
+In the above example, we are "trimming" the fields, converting the
+password to MD5, and running the username through the "xss_clean"
+function, which removes malicious data.
+
+**Any native PHP function that accepts one parameter can be used as a
+rule, like htmlspecialchars, trim, MD5, etc.**
+
+.. note:: You will generally want to use the prepping functions
+	**after** the validation rules so if there is an error, the original
+	data will be shown in the form.
+
+Re-populating the form
+======================
+
+Thus far we have only been dealing with errors. It's time to repopulate
+the form field with the submitted data. CodeIgniter offers several
+helper functions that permit you to do this. The one you will use most
+commonly is::
+
+	set_value('field name')
+
+Open your myform.php view file and update the **value** in each field
+using the set_value() function:
+
+**Don't forget to include each field name in the set_value()
+functions!**
+
+<html> <head> <title>My Form</title> </head> <body> <?php echo
+validation_errors(); ?> <?php echo form_open('form'); ?>
+<h5>Username</h5> <input type="text" name="username" value="<?php echo
+set_value('username'); ?>" size="50" /> <h5>Password</h5> <input
+type="text" name="password" value="<?php echo set_value('password');
+?>" size="50" /> <h5>Password Confirm</h5> <input type="text"
+name="passconf" value="<?php echo set_value('passconf'); ?>" size="50"
+/> <h5>Email Address</h5> <input type="text" name="email" value="<?php
+echo set_value('email'); ?>" size="50" /> <div><input type="submit"
+value="Submit" /></div> </form> </body> </html>
+Now reload your page and submit the form so that it triggers an error.
+Your form fields should now be re-populated
+
+.. note:: The `Function Reference <#functionreference>`_ section below
+	contains functions that permit you to re-populate <select> menus, radio
+	buttons, and checkboxes.
+
+**Important Note:** If you use an array as the name of a form field, you
+must supply it as an array to the function. Example::
+
+	<input type="text" name="colors[]" value="<?php echo set_value('colors[]'); ?>" size="50" />
+
+For more info please see the `Using Arrays as Field
+Names <#arraysasfields>`_ section below.
+
+Callbacks: Your own Validation Functions
+========================================
+
+The validation system supports callbacks to your own validation
+functions. This permits you to extend the validation class to meet your
+needs. For example, if you need to run a database query to see if the
+user is choosing a unique username, you can create a callback function
+that does that. Let's create a example of this.
+
+In your controller, change the "username" rule to this::
+
+	$this->form_validation->set_rules('username', 'Username', 'callback_username_check');
+
+Then add a new function called username_check to your controller.
+Here's how your controller should now look:
+
+<?php class Form extends CI_Controller { public function index() {
+$this->load->helper(array('form', 'url'));
+$this->load->library('form_validation');
+$this->form_validation->set_rules('username', 'Username',
+'callback_username_check');
+$this->form_validation->set_rules('password', 'Password', 'required');
+$this->form_validation->set_rules('passconf', 'Password Confirmation',
+'required'); $this->form_validation->set_rules('email', 'Email',
+'required\|is_unique[users.email]'); if ($this->form_validation->run()
+== FALSE) { $this->load->view('myform'); } else {
+$this->load->view('formsuccess'); } } public function
+username_check($str) { if ($str == 'test') {
+$this->form_validation->set_message('username_check', 'The %s field
+can not be the word "test"'); return FALSE; } else { return TRUE; } } }
+?>
+Reload your form and submit it with the word "test" as the username. You
+can see that the form field data was passed to your callback function
+for you to process.
+
+To invoke a callback just put the function name in a rule, with
+"callback\_" as the rule **prefix**. If you need to receive an extra
+parameter in your callback function, just add it normally after the
+function name between square brackets, as in: "callback_foo**[bar]**",
+then it will be passed as the second argument of your callback function.
+
+.. note:: You can also process the form data that is passed to your
+	callback and return it. If your callback returns anything other than a
+	boolean TRUE/FALSE it is assumed that the data is your newly processed
+	form data.
+
+Setting Error Messages
+======================
+
+All of the native error messages are located in the following language
+file: language/english/form_validation_lang.php
+
+To set your own custom message you can either edit that file, or use the
+following function::
+
+	$this->form_validation->set_message('rule', 'Error Message');
+
+Where rule corresponds to the name of a particular rule, and Error
+Message is the text you would like displayed.
+
+If you include %s in your error string, it will be replaced with the
+"human" name you used for your field when you set your rules.
+
+In the "callback" example above, the error message was set by passing
+the name of the function::
+
+	$this->form_validation->set_message('username_check')
+
+You can also override any error message found in the language file. For
+example, to change the message for the "required" rule you will do this::
+
+	$this->form_validation->set_message('required', 'Your custom message here');
+
+Translating Field Names
+=======================
+
+If you would like to store the "human" name you passed to the
+set_rules() function in a language file, and therefore make the name
+able to be translated, here's how:
+
+First, prefix your "human" name with lang:, as in this example::
+
+	 $this->form_validation->set_rules('first_name', 'lang:first_name', 'required');
+
+Then, store the name in one of your language file arrays (without the
+prefix)::
+
+	$lang['first_name'] = 'First Name';
+
+.. note:: If you store your array item in a language file that is not
+	loaded automatically by CI, you'll need to remember to load it in your
+	controller using::
+
+	$this->lang->load('file_name');
+
+See the :doc:`Language Class <language>` page for more info regarding
+language files.
+
+Changing the Error Delimiters
+=============================
+
+By default, the Form Validation class adds a paragraph tag (<p>) around
+each error message shown. You can either change these delimiters
+globally or individually.
+
+#. **Changing delimiters Globally**
+   To globally change the error delimiters, in your controller function,
+   just after loading the Form Validation class, add this:
+
+   ::
+
+	$this->form_validation->set_error_delimiters('<div class="error">', '</div>');
+
+   In this example, we've switched to using div tags.
+
+#. **Changing delimiters Individually**
+   Each of the two error generating functions shown in this tutorial can
+   be supplied their own delimiters as follows:
+
+   ::
+
+	<?php echo form_error('field name', '<div class="error">', '</div>'); ?>
+
+   Or:
+
+   ::
+
+	<?php echo validation_errors('<div class="error">', '</div>'); ?>
+
+
+Showing Errors Individually
+===========================
+
+If you prefer to show an error message next to each form field, rather
+than as a list, you can use the form_error() function.
+
+Try it! Change your form so that it looks like this:
+
+<h5>Username</h5> <?php echo form_error('username'); ?> <input
+type="text" name="username" value="<?php echo set_value('username');
+?>" size="50" /> <h5>Password</h5> <?php echo form_error('password');
+?> <input type="text" name="password" value="<?php echo
+set_value('password'); ?>" size="50" /> <h5>Password Confirm</h5> <?php
+echo form_error('passconf'); ?> <input type="text" name="passconf"
+value="<?php echo set_value('passconf'); ?>" size="50" /> <h5>Email
+Address</h5> <?php echo form_error('email'); ?> <input type="text"
+name="email" value="<?php echo set_value('email'); ?>" size="50" />
+If there are no errors, nothing will be shown. If there is an error, the
+message will appear.
+
+**Important Note:** If you use an array as the name of a form field, you
+must supply it as an array to the function. Example::
+
+	<?php echo form_error('options[size]'); ?> <input type="text" name="options[size]" value="<?php echo set_value("options[size]"); ?>" size="50" />
+
+For more info please see the `Using Arrays as Field
+Names <#arraysasfields>`_ section below.
+
+************************************************
+Saving Sets of Validation Rules to a Config File
+************************************************
+
+A nice feature of the Form Validation class is that it permits you to
+store all your validation rules for your entire application in a config
+file. You can organize these rules into "groups". These groups can
+either be loaded automatically when a matching controller/function is
+called, or you can manually call each set as needed.
+
+How to save your rules
+======================
+
+To store your validation rules, simply create a file named
+form_validation.php in your application/config/ folder. In that file
+you will place an array named $config with your rules. As shown earlier,
+the validation array will have this prototype::
+
+	 $config = array(                array(                      'field'   => 'username',                       'label'   => 'Username',                       'rules'   => 'required'                   ),                array(                      'field'   => 'password',                       'label'   => 'Password',                       'rules'   => 'required'                   ),                array(                      'field'   => 'passconf',                       'label'   => 'Password Confirmation',                       'rules'   => 'required'                   ),                   array(                      'field'   => 'email',                       'label'   => 'Email',                       'rules'   => 'required'                   )             );
+
+Your validation rule file will be loaded automatically and used when you
+call the run() function.
+
+Please note that you MUST name your array $config.
+
+Creating Sets of Rules
+======================
+
+In order to organize your rules into "sets" requires that you place them
+into "sub arrays". Consider the following example, showing two sets of
+rules. We've arbitrarily called these two rules "signup" and "email".
+You can name your rules anything you want::
+
+	$config = array(                  'signup' => array(                                     array(                                             'field' => 'username',                                             'label' => 'Username',                                             'rules' => 'required'                                          ),                                     array(                                             'field' => 'password',                                             'label' => 'Password',                                             'rules' => 'required'                                          ),                                     array(                                             'field' => 'passconf',                                             'label' => 'PasswordConfirmation',                                             'rules' => 'required'                                          ),                                     array(                                             'field' => 'email',                                             'label' => 'Email',                                             'rules' => 'required'                                          )                                     ),                  'email' => array(                                     array(                                             'field' => 'emailaddress',                                             'label' => 'EmailAddress',                                             'rules' => 'required|valid_email'                                          ),                                     array(                                             'field' => 'name',                                             'label' => 'Name',                                             'rules' => 'required|alpha'                                          ),                                     array(                                             'field' => 'title',                                             'label' => 'Title',                                             'rules' => 'required'                                          ),                                     array(                                             'field' => 'message',                                             'label' => 'MessageBody',                                             'rules' => 'required'                                          )                                     )                                          );
+
+Calling a Specific Rule Group
+=============================
+
+In order to call a specific group you will pass its name to the run()
+function. For example, to call the signup rule you will do this::
+
+	 if ($this->form_validation->run('signup') == FALSE) {    $this->load->view('myform'); } else {    $this->load->view('formsuccess'); }
+
+Associating a Controller Function with a Rule Group
+===================================================
+
+An alternate (and more automatic) method of calling a rule group is to
+name it according to the controller class/function you intend to use it
+with. For example, let's say you have a controller named Member and a
+function named signup. Here's what your class might look like::
+
+	 <?php class Member extends CI_Controller {     function signup()    {             $this->load->library('form_validation');                    if ($this->form_validation->run() == FALSE)       {          $this->load->view('myform');       }       else       {          $this->load->view('formsuccess');       }    } } ?>
+
+In your validation config file, you will name your rule group
+member/signup::
+
+	$config = array(            'member/signup' => array(                                     array(                                             'field' => 'username',                                             'label' => 'Username',                                             'rules' => 'required'                                          ),                                     array(                                             'field' => 'password',                                             'label' => 'Password',                                             'rules' => 'required'                                          ),                                     array(                                             'field' => 'passconf',                                             'label' => 'PasswordConfirmation',                                             'rules' => 'required'                                          ),                                     array(                                             'field' => 'email',                                             'label' => 'Email',                                             'rules' => 'required'                                          )                                     )                );
+
+When a rule group is named identically to a controller class/function it
+will be used automatically when the run() function is invoked from that
+class/function.
+
+***************************
+Using Arrays as Field Names
+***************************
+
+The Form Validation class supports the use of arrays as field names.
+Consider this example::
+
+	<input type="text" name="options[]" value="" size="50" />
+
+If you do use an array as a field name, you must use the EXACT array
+name in the `Helper Functions <#helperreference>`_ that require the
+field name, and as your Validation Rule field name.
+
+For example, to set a rule for the above field you would use::
+
+	$this->form_validation->set_rules('options[]', 'Options', 'required');
+
+Or, to show an error for the above field you would use::
+
+	<?php echo form_error('options[]'); ?>
+
+Or to re-populate the field you would use::
+
+	<input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>" size="50" />
+
+You can use multidimensional arrays as field names as well. For example::
+
+	<input type="text" name="options[size]" value="" size="50" />
+
+Or even::
+
+	<input type="text" name="sports[nba][basketball]" value="" size="50" />
+
+As with our first example, you must use the exact array name in the
+helper functions::
+
+	<?php echo form_error('sports[nba][basketball]'); ?>
+
+If you are using checkboxes (or other fields) that have multiple
+options, don't forget to leave an empty bracket after each option, so
+that all selections will be added to the POST array::
+
+	 <input type="checkbox" name="options[]" value="red" /> <input type="checkbox" name="options[]" value="blue" /> <input type="checkbox" name="options[]" value="green" />
+
+Or if you use a multidimensional array::
+
+	 <input type="checkbox" name="options[color][]" value="red" /> <input type="checkbox" name="options[color][]" value="blue" /> <input type="checkbox" name="options[color][]" value="green" />
+
+When you use a helper function you'll include the bracket as well::
+
+	<?php echo form_error('options[color][]'); ?>
+

+******************
+Function Reference
+******************
+
+The following functions are intended for use in your controller
+functions.
+
+$this->form_validation->set_rules();
+======================================
+
+Permits you to set validation rules, as described in the tutorial
+sections above:
+
+-  `Setting Validation Rules <#validationrules>`_
+-  `Saving Groups of Validation Rules to a Config
+   File <#savingtoconfig>`_
+
+$this->form_validation->run();
+===============================
+
+Runs the validation routines. Returns boolean TRUE on success and FALSE
+on failure. You can optionally pass the name of the validation group via
+the function, as described in: `Saving Groups of Validation Rules to a
+Config File <#savingtoconfig>`_.
+
+$this->form_validation->set_message();
+========================================
+
+Permits you to set custom error messages. See `Setting Error
+Messages <#settingerrors>`_ above.
+
+****************
+Helper Reference
+****************
+
+The following helper functions are available for use in the view files
+containing your forms. Note that these are procedural functions, so they
+**do not** require you to prepend them with $this->form_validation.
+
+form_error()
+=============
+
+Shows an individual error message associated with the field name
+supplied to the function. Example::
+
+	<?php echo form_error('username'); ?>
+
+The error delimiters can be optionally specified. See the `Changing the
+Error Delimiters <#errordelimiters>`_ section above.
+
+validation_errors()
+====================
+
+Shows all error messages as a string: Example::
+
+	<?php echo validation_errors(); ?>
+
+The error delimiters can be optionally specified. See the `Changing the
+Error Delimiters <#errordelimiters>`_ section above.
+
+set_value()
+============
+
+Permits you to set the value of an input form or textarea. You must
+supply the field name via the first parameter of the function. The
+second (optional) parameter allows you to set a default value for the
+form. Example::
+
+	<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" />
+
+The above form will show "0" when loaded for the first time.
+
+set_select()
+=============
+
+If you use a <select> menu, this function permits you to display the
+menu item that was selected. The first parameter must contain the name
+of the select menu, the second parameter must contain the value of each
+item, and the third (optional) parameter lets you set an item as the
+default (use boolean TRUE/FALSE).
+
+Example::
+
+	 <select name="myselect"> <option value="one" <?php echo  set_select('myselect', 'one', TRUE); ?> >One</option> <option value="two" <?php echo  set_select('myselect', 'two'); ?> >Two</option> <option value="three" <?php echo  set_select('myselect', 'three'); ?> >Three</option> </select>
+
+set_checkbox()
+===============
+
+Permits you to display a checkbox in the state it was submitted. The
+first parameter must contain the name of the checkbox, the second
+parameter must contain its value, and the third (optional) parameter
+lets you set an item as the default (use boolean TRUE/FALSE). Example::
+
+	<input type="checkbox" name="mycheck[]" value="1" <?php echo set_checkbox('mycheck[]', '1'); ?> /> <input type="checkbox" name="mycheck[]" value="2" <?php echo set_checkbox('mycheck[]', '2'); ?> />
+
+set_radio()
+============
+
+Permits you to display radio buttons in the state they were submitted.
+This function is identical to the **set_checkbox()** function above.
+
+::
+
+	<input type="radio" name="myradio" value="1" <?php echo  set_radio('myradio', '1', TRUE); ?> /> <input type="radio" name="myradio" value="2" <?php echo  set_radio('myradio', '2'); ?> />

+FTP Class
+#########
+
+CodeIgniter's FTP Class permits files to be transfered to a remote
+server. Remote files can also be moved, renamed, and deleted. The FTP
+class also includes a "mirroring" function that permits an entire local
+directory to be recreated remotely via FTP.
+
+.. note:: SFTP and SSL FTP protocols are not supported, only standard
+	FTP.
+
+**********************
+Initializing the Class
+**********************
+
+Like most other classes in CodeIgniter, the FTP class is initialized in
+your controller using the $this->load->library function::
+
+	$this->load->library('ftp');
+
+Once loaded, the FTP object will be available using: $this->ftp
+
+Usage Examples
+==============
+
+In this example a connection is opened to the FTP server, and a local
+file is read and uploaded in ASCII mode. The file permissions are set to
+755. Note: Setting permissions requires PHP 5.
+
+::
+
+	 $this->load->library('ftp');  $config['hostname'] = 'ftp.example.com'; $config['username'] = 'your-username'; $config['password'] = 'your-password'; $config['debug']    = TRUE;  $this->ftp->connect($config);  $this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775);  $this->ftp->close(); 
+
+In this example a list of files is retrieved from the server.
+
+::
+
+	 $this->load->library('ftp');  $config['hostname'] = 'ftp.example.com'; $config['username'] = 'your-username'; $config['password'] = 'your-password'; $config['debug']    = TRUE;  $this->ftp->connect($config);  $list = $this->ftp->list_files('/public_html/');  print_r($list);  $this->ftp->close();
+
+In this example a local directory is mirrored on the server.
+
+::
+
+	 $this->load->library('ftp');  $config['hostname'] = 'ftp.example.com'; $config['username'] = 'your-username'; $config['password'] = 'your-password'; $config['debug']    = TRUE;  $this->ftp->connect($config);  $this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/');  $this->ftp->close();
+
+******************
+Function Reference
+******************
+
+$this->ftp->connect()
+=====================
+
+Connects and logs into to the FTP server. Connection preferences are set
+by passing an array to the function, or you can store them in a config
+file.
+
+Here is an example showing how you set preferences manually::
+
+	 $this->load->library('ftp');  $config['hostname'] = 'ftp.example.com'; $config['username'] = 'your-username'; $config['password'] = 'your-password'; $config['port']     = 21; $config['passive']  = FALSE; $config['debug']    = TRUE;  $this->ftp->connect($config);

+****************************************
+
+If you prefer you can store your FTP preferences in a config file.
+Simply create a new file called the ftp.php, add the $config array in
+that file. Then save the file at config/ftp.php and it will be used
+automatically.
+
+Available connection options
+****************************
+
+-  **hostname** - the FTP hostname. Usually something like:
+   ftp.example.com
+-  **username** - the FTP username.
+-  **password** - the FTP password.
+-  **port** - The port number. Set to 21 by default.
+-  **debug** - TRUE/FALSE (boolean). Whether to enable debugging to
+   display error messages.
+-  **passive** - TRUE/FALSE (boolean). Whether to use passive mode.
+   Passive is set automatically by default.
+
+$this->ftp->upload()
+====================
+
+Uploads a file to your server. You must supply the local path and the
+remote path, and you can optionally set the mode and permissions.
+Example::
+
+	$this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775);
+
+**Mode options are:** ascii, binary, and auto (the default). If auto is
+used it will base the mode on the file extension of the source file.
+
+Permissions are available if you are running PHP 5 and can be passed as
+an octal value in the fourth parameter.
+
+$this->ftp->download()
+======================
+
+Downloads a file from your server. You must supply the remote path and
+the local path, and you can optionally set the mode. Example::
+
+	$this->ftp->download('/public_html/myfile.html', '/local/path/to/myfile.html', 'ascii');
+
+**Mode options are:** ascii, binary, and auto (the default). If auto is
+used it will base the mode on the file extension of the source file.
+
+Returns FALSE if the download does not execute successfully (including
+if PHP does not have permission to write the local file)
+
+$this->ftp->rename()
+====================
+
+Permits you to rename a file. Supply the source file name/path and the
+new file name/path.
+
+::
+
+	 // Renames green.html to blue.html $this->ftp->rename('/public_html/foo/green.html', '/public_html/foo/blue.html');
+
+$this->ftp->move()
+==================
+
+Lets you move a file. Supply the source and destination paths::
+
+	 // Moves blog.html from "joe" to "fred" $this->ftp->move('/public_html/joe/blog.html', '/public_html/fred/blog.html');
+
+Note: if the destination file name is different the file will be
+renamed.
+
+$this->ftp->delete_file()
+==========================
+
+Lets you delete a file. Supply the source path with the file name.
+
+::
+
+	 $this->ftp->delete_file('/public_html/joe/blog.html');
+
+$this->ftp->delete_dir()
+=========================
+
+Lets you delete a directory and everything it contains. Supply the
+source path to the directory with a trailing slash.
+
+**Important** Be VERY careful with this function. It will recursively
+delete **everything** within the supplied path, including sub-folders
+and all files. Make absolutely sure your path is correct. Try using the
+list_files() function first to verify that your path is correct.
+
+::
+
+	 $this->ftp->delete_dir('/public_html/path/to/folder/');
+
+$this->ftp->list_files()
+=========================
+
+Permits you to retrieve a list of files on your server returned as an
+array. You must supply the path to the desired directory.
+
+::
+
+	 $list = $this->ftp->list_files('/public_html/');  print_r($list);
+
+$this->ftp->mirror()
+====================
+
+Recursively reads a local folder and everything it contains (including
+sub-folders) and creates a mirror via FTP based on it. Whatever the
+directory structure of the original file path will be recreated on the
+server. You must supply a source path and a destination path::
+
+	 $this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/');
+
+$this->ftp->mkdir()
+===================
+
+Lets you create a directory on your server. Supply the path ending in
+the folder name you wish to create, with a trailing slash. Permissions
+can be set by passed an octal value in the second parameter (if you are
+running PHP 5).
+
+::
+
+	 // Creates a folder named "bar" $this->ftp->mkdir('/public_html/foo/bar/', DIR_WRITE_MODE);
+
+$this->ftp->chmod()
+===================
+
+Permits you to set file permissions. Supply the path to the file or
+folder you wish to alter permissions on::
+
+	 // Chmod "bar" to 777 $this->ftp->chmod('/public_html/foo/bar/', DIR_WRITE_MODE);
+
+$this->ftp->close();
+====================
+
+Closes the connection to your server. It's recommended that you use this
+when you are finished uploading.

+########################
+Image Manipulation Class
+########################
+
+CodeIgniter's Image Manipulation class lets you perform the following
+actions:
+
+-  Image Resizing
+-  Thumbnail Creation
+-  Image Cropping
+-  Image Rotating
+-  Image Watermarking
+
+All three major image libraries are supported: GD/GD2, NetPBM, and
+ImageMagick
+
+.. note:: Watermarking is only available using the GD/GD2 library. In
+	addition, even though other libraries are supported, GD is required in
+	order for the script to calculate the image properties. The image
+	processing, however, will be performed with the library you specify.
+
+**********************
+Initializing the Class
+**********************
+
+Like most other classes in CodeIgniter, the image class is initialized
+in your controller using the $this->load->library function::
+
+	$this->load->library('image_lib');
+
+Once the library is loaded it will be ready for use. The image library
+object you will use to call all functions is: $this->image_lib
+
+Processing an Image
+===================
+
+Regardless of the type of processing you would like to perform
+(resizing, cropping, rotation, or watermarking), the general process is
+identical. You will set some preferences corresponding to the action you
+intend to perform, then call one of four available processing functions.
+For example, to create an image thumbnail you'll do this::
+
+	$config['image_library'] = 'gd2'; $config['source_image'] = '/path/to/image/mypic.jpg'; $config['create_thumb'] = TRUE; $config['maintain_ratio'] = TRUE; $config['width']        = 75; $config['height']   = 50;  $this->load->library('image_lib', $config);   $this->image_lib->resize();
+
+The above code tells the image_resize function to look for an image
+called *mypic.jpg* located in the source_image folder, then create a
+thumbnail that is 75 X 50 pixels using the GD2 image_library. Since the
+maintain_ratio option is enabled, the thumb will be as close to the
+target width and height as possible while preserving the original aspect
+ratio. The thumbnail will be called *mypic_thumb.jpg*
+
+.. note:: In order for the image class to be allowed to do any
+	processing, the folder containing the image files must have write
+	permissions.
+
+.. note:: Image processing can require a considerable amount of server
+	memory for some operations. If you are experiencing out of memory errors
+	while processing images you may need to limit their maximum size, and/or
+	adjust PHP memory limits.
+
+Processing Functions
+====================
+
+There are four available processing functions:
+
+-  $this->image_lib->resize()
+-  $this->image_lib->crop()
+-  $this->image_lib->rotate()
+-  $this->image_lib->watermark()
+-  $this->image_lib->clear()
+
+These functions return boolean TRUE upon success and FALSE for failure.
+If they fail you can retrieve the error message using this function::
+
+	echo $this->image_lib->display_errors();
+
+A good practice is use the processing function conditionally, showing an
+error upon failure, like this::
+
+	if ( ! $this->image_lib->resize()) {     echo $this->image_lib->display_errors(); }
+
+Note: You can optionally specify the HTML formatting to be applied to
+the errors, by submitting the opening/closing tags in the function, like
+this::
+
+	$this->image_lib->display_errors('<p>', '</p>');
+
+Preferences
+===========
+
+The preferences described below allow you to tailor the image processing
+to suit your needs.
+
+Note that not all preferences are available for every function. For
+example, the x/y axis preferences are only available for image cropping.
+Likewise, the width and height preferences have no effect on cropping.
+The "availability" column indicates which functions support a given
+preference.
+
+Availability Legend:
+
+-  R - Image Resizing
+-  C - Image Cropping
+-  X - Image Rotation
+-  W - Image Watermarking
+
+Preference
+Default Value
+Options
+Description
+Availability
+**image_library**
+GD2
+GD, GD2, ImageMagick, NetPBM
+Sets the image library to be used.
+R, C, X, W
+**library_path**
+None
+None
+Sets the server path to your ImageMagick or NetPBM library. If you use
+either of those libraries you must supply the path.
+R, C, X
+**source_image**
+None
+None
+Sets the source image name/path. The path must be a relative or absolute
+server path, not a URL.
+R, C, S, W
+**dynamic_output**
+FALSE
+TRUE/FALSE (boolean)
+Determines whether the new image file should be written to disk or
+generated dynamically. Note: If you choose the dynamic setting, only one
+image can be shown at a time, and it can't be positioned on the page. It
+simply outputs the raw image dynamically to your browser, along with
+image headers.
+R, C, X, W
+**quality**
+90%
+1 - 100%
+Sets the quality of the image. The higher the quality the larger the
+file size.
+R, C, X, W
+**new_image**
+None
+None
+Sets the destination image name/path. You'll use this preference when
+creating an image copy. The path must be a relative or absolute server
+path, not a URL.
+R, C, X, W
+**width**
+None
+None
+Sets the width you would like the image set to.
+R, C
+**height**
+None
+None
+Sets the height you would like the image set to.
+R, C
+**create_thumb**
+FALSE
+TRUE/FALSE (boolean)
+Tells the image processing function to create a thumb.
+R
+**thumb_marker**
+_thumb
+None
+Specifies the thumbnail indicator. It will be inserted just before the
+file extension, so mypic.jpg would become mypic_thumb.jpg
+R
+**maintain_ratio**
+TRUE
+TRUE/FALSE (boolean)
+Specifies whether to maintain the original aspect ratio when resizing or
+use hard values.
+R, C
+**master_dim**
+auto
+auto, width, height
+Specifies what to use as the master axis when resizing or creating
+thumbs. For example, let's say you want to resize an image to 100 X 75
+pixels. If the source image size does not allow perfect resizing to
+those dimensions, this setting determines which axis should be used as
+the hard value. "auto" sets the axis automatically based on whether the
+image is taller then wider, or vice versa.
+R
+**rotation_angle**
+None
+90, 180, 270, vrt, hor
+Specifies the angle of rotation when rotating images. Note that PHP
+rotates counter-clockwise, so a 90 degree rotation to the right must be
+specified as 270.
+X
+**x_axis**
+None
+None
+Sets the X coordinate in pixels for image cropping. For example, a
+setting of 30 will crop an image 30 pixels from the left.
+C
+**y_axis**
+None
+None
+Sets the Y coordinate in pixels for image cropping. For example, a
+setting of 30 will crop an image 30 pixels from the top.
+C
+Setting preferences in a config file
+====================================
+
+If you prefer not to set preferences using the above method, you can
+instead put them into a config file. Simply create a new file called
+image_lib.php, add the $config array in that file. Then save the file
+in: config/image_lib.php and it will be used automatically. You will
+NOT need to use the $this->image_lib->initialize function if you save
+your preferences in a config file.
+
+$this->image_lib->resize()
+===========================
+
+The image resizing function lets you resize the original image, create a
+copy (with or without resizing), or create a thumbnail image.
+
+For practical purposes there is no difference between creating a copy
+and creating a thumbnail except a thumb will have the thumbnail marker
+as part of the name (ie, mypic_thumb.jpg).
+
+All preferences listed in the table above are available for this
+function except these three: rotation_angle, x_axis, and y_axis.
+
+Creating a Thumbnail
+--------------------
+
+The resizing function will create a thumbnail file (and preserve the
+original) if you set this preference to TRUE::
+
+	$config['create_thumb'] = TRUE;
+
+This single preference determines whether a thumbnail is created or not.
+
+Creating a Copy
+---------------
+
+The resizing function will create a copy of the image file (and preserve
+the original) if you set a path and/or a new filename using this
+preference::
+
+	$config['new_image'] = '/path/to/new_image.jpg';
+
+Notes regarding this preference:
+
+-  If only the new image name is specified it will be placed in the same
+   folder as the original
+-  If only the path is specified, the new image will be placed in the
+   destination with the same name as the original.
+-  If both the path and image name are specified it will placed in its
+   own destination and given the new name.
+
+Resizing the Original Image
+---------------------------
+
+If neither of the two preferences listed above (create_thumb, and
+new_image) are used, the resizing function will instead target the
+original image for processing.
+
+$this->image_lib->crop()
+=========================
+
+The cropping function works nearly identically to the resizing function
+except it requires that you set preferences for the X and Y axis (in
+pixels) specifying where to crop, like this::
+
+	$config['x_axis'] = '100'; $config['y_axis'] = '40';
+
+All preferences listed in the table above are available for this
+function except these: rotation_angle, width, height, create_thumb,
+new_image.
+
+Here's an example showing how you might crop an image::
+
+	$config['image_library'] = 'imagemagick'; $config['library_path'] = '/usr/X11R6/bin/'; $config['source_image'] = '/path/to/image/mypic.jpg'; $config['x_axis'] = '100'; $config['y_axis'] = '60';  $this->image_lib->initialize($config);   if ( ! $this->image_lib->crop()) {     echo $this->image_lib->display_errors(); }
+
+Note: Without a visual interface it is difficult to crop images, so this
+function is not very useful unless you intend to build such an
+interface. That's exactly what we did using for the photo gallery module
+in ExpressionEngine, the CMS we develop. We added a JavaScript UI that
+lets the cropping area be selected.
+
+$this->image_lib->rotate()
+===========================
+
+The image rotation function requires that the angle of rotation be set
+via its preference::
+
+	$config['rotation_angle'] = '90';
+
+There are 5 rotation options:
+
+#. 90 - rotates counter-clockwise by 90 degrees.
+#. 180 - rotates counter-clockwise by 180 degrees.
+#. 270 - rotates counter-clockwise by 270 degrees.
+#. hor - flips the image horizontally.
+#. vrt - flips the image vertically.
+
+Here's an example showing how you might rotate an image::
+
+	$config['image_library'] = 'netpbm'; $config['library_path'] = '/usr/bin/'; $config['source_image'] = '/path/to/image/mypic.jpg'; $config['rotation_angle'] = 'hor';  $this->image_lib->initialize($config);   if ( ! $this->image_lib->rotate()) {     echo $this->image_lib->display_errors(); }
+
+$this->image_lib->clear()
+==========================
+
+The clear function resets all of the values used when processing an
+image. You will want to call this if you are processing images in a
+loop.
+
+::
+
+	$this->image_lib->clear();
+
+
+******************
+Image Watermarking
+******************
+
+The Watermarking feature requires the GD/GD2 library.
+
+Two Types of Watermarking
+=========================
+
+There are two types of watermarking that you can use:
+
+-  **Text**: The watermark message will be generating using text, either
+   with a True Type font that you specify, or using the native text
+   output that the GD library supports. If you use the True Type version
+   your GD installation must be compiled with True Type support (most
+   are, but not all).
+-  **Overlay**: The watermark message will be generated by overlaying an
+   image (usually a transparent PNG or GIF) containing your watermark
+   over the source image.
+
+Watermarking an Image
+=====================
+
+Just as with the other functions (resizing, cropping, and rotating) the
+general process for watermarking involves setting the preferences
+corresponding to the action you intend to perform, then calling the
+watermark function. Here is an example::
+
+	 $config['source_image'] = '/path/to/image/mypic.jpg'; $config['wm_text'] = 'Copyright 2006 - John Doe'; $config['wm_type'] = 'text'; $config['wm_font_path'] = './system/fonts/texb.ttf'; $config['wm_font_size'] = '16'; $config['wm_font_color'] = 'ffffff'; $config['wm_vrt_alignment']  = 'bottom'; $config['wm_hor_alignment']  = 'center'; $config['wm_padding']  = '20';  $this->image_lib->initialize($config);   $this->image_lib->watermark();
+
+The above example will use a 16 pixel True Type font to create the text
+"Copyright 2006 - John Doe". The watermark will be positioned at the
+bottom/center of the image, 20 pixels from the bottom of the image.
+
+.. note:: In order for the image class to be allowed to do any
+	processing, the image file must have "write" file permissions. For
+	example, 777.
+
+Watermarking Preferences
+========================
+
+This table shown the preferences that are available for both types of
+watermarking (text or overlay)
+
+Preference
+Default Value
+Options
+Description
+**wm_type**
+text
+text, overlay
+Sets the type of watermarking that should be used.
+**source_image**
+None
+None
+Sets the source image name/path. The path must be a relative or absolute
+server path, not a URL.
+**dynamic_output**
+FALSE
+TRUE/FALSE (boolean)
+Determines whether the new image file should be written to disk or
+generated dynamically. Note: If you choose the dynamic setting, only one
+image can be shown at a time, and it can't be positioned on the page. It
+simply outputs the raw image dynamically to your browser, along with
+image headers.
+**quality**
+90%
+1 - 100%
+Sets the quality of the image. The higher the quality the larger the
+file size.
+**padding**
+None
+A number
+The amount of padding, set in pixels, that will be applied to the
+watermark to set it away from the edge of your images.
+**wm_vrt_alignment**
+bottom
+top, middle, bottom
+Sets the vertical alignment for the watermark image.
+**wm_hor_alignment**
+center
+left, center, right
+Sets the horizontal alignment for the watermark image.
+**wm_hor_offset**
+None
+None
+You may specify a horizontal offset (in pixels) to apply to the
+watermark position. The offset normally moves the watermark to the
+right, except if you have your alignment set to "right" then your offset
+value will move the watermark toward the left of the image.
+**wm_vrt_offset**
+None
+None
+You may specify a vertical offset (in pixels) to apply to the watermark
+position. The offset normally moves the watermark down, except if you
+have your alignment set to "bottom" then your offset value will move the
+watermark toward the top of the image.
+Text Preferences
+----------------
+
+This table shown the preferences that are available for the text type of
+watermarking.
+
+Preference
+Default Value
+Options
+Description
+**wm_text**
+None
+None
+The text you would like shown as the watermark. Typically this will be a
+copyright notice.
+**wm_font_path**
+None
+None
+The server path to the True Type Font you would like to use. If you do
+not use this option, the native GD font will be used.
+**wm_font_size**
+16
+None
+The size of the text. Note: If you are not using the True Type option
+above, the number is set using a range of 1 - 5. Otherwise, you can use
+any valid pixel size for the font you're using.
+**wm_font_color**
+ffffff
+None
+The font color, specified in hex. Note, you must use the full 6
+character hex value (ie, 993300), rather than the three character
+abbreviated version (ie fff).
+**wm_shadow_color**
+None
+None
+The color of the drop shadow, specified in hex. If you leave this blank
+a drop shadow will not be used. Note, you must use the full 6 character
+hex value (ie, 993300), rather than the three character abbreviated
+version (ie fff).
+**wm_shadow_distance**
+3
+None
+The distance (in pixels) from the font that the drop shadow should
+appear.
+Overlay Preferences
+-------------------
+
+This table shown the preferences that are available for the overlay type
+of watermarking.
+
+Preference
+Default Value
+Options
+Description
+**wm_overlay_path**
+None
+None
+The server path to the image you wish to use as your watermark. Required
+only if you are using the overlay method.
+**wm_opacity**
+50
+1 - 100
+Image opacity. You may specify the opacity (i.e. transparency) of your
+watermark image. This allows the watermark to be faint and not
+completely obscure the details from the original image behind it. A 50%
+opacity is typical.
+**wm_x_transp**
+4
+A number
+If your watermark image is a PNG or GIF image, you may specify a color
+on the image to be "transparent". This setting (along with the next)
+will allow you to specify that color. This works by specifying the "X"
+and "Y" coordinate pixel (measured from the upper left) within the image
+that corresponds to a pixel representative of the color you want to be
+transparent.
+**wm_y_transp**
+4
+A number
+Along with the previous setting, this allows you to specify the
+coordinate to a pixel representative of the color you want to be
+transparent.

+###########
+Input Class
+###########
+
+The Input Class serves two purposes:
+
+#. It pre-processes global input data for security.
+#. It provides some helper functions for fetching input data and
+   pre-processing it.
+
+.. note:: This class is initialized automatically by the system so there
+	is no need to do it manually.
+
+Security Filtering
+==================
+
+The security filtering function is called automatically when a new
+:doc:`controller <../general/controllers>` is invoked. It does the
+following:
+
+-  If $config['allow_get_array'] is FALSE(default is TRUE), destroys
+   the global GET array.
+-  Destroys all global variables in the event register_globals is
+   turned on.
+-  Filters the GET/POST/COOKIE array keys, permitting only alpha-numeric
+   (and a few other) characters.
+-  Provides XSS (Cross-site Scripting Hacks) filtering. This can be
+   enabled globally, or upon request.
+-  Standardizes newline characters to \\n(In Windows \\r\\n)
+
+XSS Filtering
+=============
+
+The Input class has the ability to filter input automatically to prevent
+cross-site scripting attacks. If you want the filter to run
+automatically every time it encounters POST or COOKIE data you can
+enable it by opening your application/config/config.php file and setting
+this::
+
+	$config['global_xss_filtering'] = TRUE;
+
+Please refer to the :doc:`Security class <security>` documentation for
+information on using XSS Filtering in your application.
+
+Using POST, COOKIE, or SERVER Data
+==================================
+
+CodeIgniter comes with three helper functions that let you fetch POST,
+COOKIE or SERVER items. The main advantage of using the provided
+functions rather than fetching an item directly ($_POST['something'])
+is that the functions will check to see if the item is set and return
+false (boolean) if not. This lets you conveniently use data without
+having to test whether an item exists first. In other words, normally
+you might do something like this::
+
+	 if ( ! isset($_POST['something'])) {     $something = FALSE; } else {     $something = $_POST['something']; }
+
+With CodeIgniter's built in functions you can simply do this::
+
+	$something = $this->input->post('something');
+
+The three functions are:
+
+-  $this->input->post()
+-  $this->input->cookie()
+-  $this->input->server()
+
+$this->input->post()
+====================
+
+The first parameter will contain the name of the POST item you are
+looking for::
+
+	$this->input->post('some_data');
+
+The function returns FALSE (boolean) if the item you are attempting to
+retrieve does not exist.
+
+The second optional parameter lets you run the data through the XSS
+filter. It's enabled by setting the second parameter to boolean TRUE;
+
+::
+
+	$this->input->post('some_data', TRUE);
+
+To return an array of all POST items call without any parameters.
+
+To return all POST items and pass them through the XSS filter set the
+first parameter NULL while setting the second parameter to boolean;
+
+The function returns FALSE (boolean) if there are no items in the POST.
+
+::
+
+	     $this->input->post(NULL, TRUE); // returns all POST items with XSS filter          $this->input->post(); // returns all POST items without XSS filter
+
+$this->input->get()
+===================
+
+This function is identical to the post function, only it fetches get
+data::
+
+	$this->input->get('some_data', TRUE);
+
+To return an array of all GET items call without any parameters.
+
+To return all GET items and pass them through the XSS filter set the
+first parameter NULL while setting the second parameter to boolean;
+
+The function returns FALSE (boolean) if there are no items in the GET.
+
+::
+
+	     $this->input->get(NULL, TRUE); // returns all GET items with XSS filter          $this->input->get(); // returns all GET items without XSS filtering
+
+$this->input->get_post()
+=========================
+
+This function will search through both the post and get streams for
+data, looking first in post, and then in get::
+
+	$this->input->get_post('some_data', TRUE);
+
+$this->input->cookie()
+======================
+
+This function is identical to the post function, only it fetches cookie
+data::
+
+	$this->input->cookie('some_data', TRUE);
+
+$this->input->server()
+======================
+
+This function is identical to the above functions, only it fetches
+server data::
+
+	$this->input->server('some_data');
+
+$this->input->set_cookie()
+===========================
+
+Sets a cookie containing the values you specify. There are two ways to
+pass information to this function so that a cookie can be set: Array
+Method, and Discrete Parameters:
+
+Array Method
+^^^^^^^^^^^^
+
+Using this method, an associative array is passed to the first
+parameter::
+
+	$cookie = array(     'name'   => 'The Cookie Name',     'value'  => 'The Value',     'expire' => '86500',     'domain' => '.some-domain.com',     'path'   => '/',     'prefix' => 'myprefix_',     'secure' => TRUE );  $this->input->set_cookie($cookie);
+
+**Notes:**
+
+Only the name and value are required. To delete a cookie set it with the
+expiration blank.
+
+The expiration is set in **seconds**, which will be added to the current
+time. Do not include the time, but rather only the number of seconds
+from *now* that you wish the cookie to be valid. If the expiration is
+set to zero the cookie will only last as long as the browser is open.
+
+For site-wide cookies regardless of how your site is requested, add your
+URL to the **domain** starting with a period, like this:
+.your-domain.com
+
+The path is usually not needed since the function sets a root path.
+
+The prefix is only needed if you need to avoid name collisions with
+other identically named cookies for your server.
+
+The secure boolean is only needed if you want to make it a secure cookie
+by setting it to TRUE.
+
+Discrete Parameters
+^^^^^^^^^^^^^^^^^^^
+
+If you prefer, you can set the cookie by passing data using individual
+parameters::
+
+	$this->input->set_cookie($name, $value, $expire, $domain, $path, $prefix, $secure);
+
+$this->input->cookie()
+======================
+
+Lets you fetch a cookie. The first parameter will contain the name of
+the cookie you are looking for (including any prefixes)::
+
+	cookie('some_cookie');
+
+The function returns FALSE (boolean) if the item you are attempting to
+retrieve does not exist.
+
+The second optional parameter lets you run the data through the XSS
+filter. It's enabled by setting the second parameter to boolean TRUE;
+
+::
+
+	cookie('some_cookie', TRUE);
+
+
+$this->input->ip_address()
+===========================
+
+Returns the IP address for the current user. If the IP address is not
+valid, the function will return an IP of: 0.0.0.0
+
+::
+
+	echo $this->input->ip_address();
+
+$this->input->valid_ip($ip)
+============================
+
+Takes an IP address as input and returns TRUE or FALSE (boolean) if it
+is valid or not. Note: The $this->input->ip_address() function above
+validates the IP automatically.
+
+::
+
+	if ( ! $this->input->valid_ip($ip)) {      echo 'Not Valid'; } else {      echo 'Valid'; }
+
+$this->input->user_agent()
+===========================
+
+Returns the user agent (web browser) being used by the current user.
+Returns FALSE if it's not available.
+
+::
+
+	echo $this->input->user_agent();
+
+See the :doc:`User Agent Class <user_agent>` for methods which extract
+information from the user agent string.
+
+$this->input->request_headers()
+================================
+
+Useful if running in a non-Apache environment where
+`apache_request_headers() <http://php.net/apache_request_headers>`_
+will not be supported. Returns an array of headers.
+
+::
+
+	$headers = $this->input->request_headers();
+
+$this->input->get_request_header();
+=====================================
+
+Returns a single member of the request headers array.
+
+::
+
+	$this->input->get_request_header('some-header', TRUE);
+
+$this->input->is_ajax_request()
+=================================
+
+Checks to see if the HTTP_X_REQUESTED_WITH server header has been
+set, and returns a boolean response.
+
+$this->input->is_cli_request()
+================================
+
+Checks to see if the STDIN constant is set, which is a failsafe way to
+see if PHP is being run on the command line.
+
+::
+
+	$this->input->is_cli_request()
+

+################
+Javascript Class
+################
+
+CodeIgniter provides a library to help you with certain common functions
+that you may want to use with Javascript. Please note that CodeIgniter
+does not require the jQuery library to run, and that any scripting
+library will work equally well. The jQuery library is simply presented
+as a convenience if you choose to use it.
+
+Initializing the Class
+======================
+
+To initialize the Javascript class manually in your controller
+constructor, use the $this->load->library function. Currently, the only
+available library is jQuery, which will automatically be loaded like
+this::
+
+	$this->load->library('javascript');
+
+The Javascript class also accepts parameters, js_library_driver
+(string) default 'jquery' and autoload (bool) default TRUE. You may
+override the defaults if you wish by sending an associative array::
+
+	$this->load->library('javascript', array('js_library_driver' => 'scripto', 'autoload' => FALSE));
+
+Again, presently only 'jquery' is available. You may wish to set
+autoload to FALSE, though, if you do not want the jQuery library to
+automatically include a script tag for the main jQuery script file. This
+is useful if you are loading it from a location outside of CodeIgniter,
+or already have the script tag in your markup.
+
+Once loaded, the jQuery library object will be available using:
+$this->javascript
+
+Setup and Configuration
+=======================
+
+Set these variables in your view
+--------------------------------
+
+As a Javascript library, your files must be available to your
+application.
+
+As Javascript is a client side language, the library must be able to
+write content into your final output. This generally means a view.
+You'll need to include the following variables in the <head> sections of
+your output.
+
+::
+
+	<?php echo $library_src;?> <?php echo $script_head;?>
+
+
+$library_src, is where the actual library file will be loaded, as well
+as any subsequent plugin script calls; $script_head is where specific
+events, functions and other commands will be rendered.
+
+Set the path to the librarys with config items
+----------------------------------------------
+
+There are some configuration items in Javascript library. These can
+either be set in application/config.php, within its own
+config/javascript.php file, or within any controller usings the
+set_item() function.
+
+An image to be used as an "ajax loader", or progress indicator. Without
+one, the simple text message of "loading" will appear when Ajax calls
+need to be made.
+
+::
+
+	$config['javascript_location'] = 'http://localhost/codeigniter/themes/js/jquery/';         $config['javascript_ajax_img'] = 'images/ajax-loader.gif';
+
+
+If you keep your files in the same directories they were downloaded
+from, then you need not set this configuration items.
+
+The jQuery Class
+================
+
+To initialize the jQuery class manually in your controller constructor,
+use the $this->load->library function::
+
+	$this->load->library('jquery');
+
+You may send an optional parameter to determine whether or not a script
+tag for the main jQuery file will be automatically included when loading
+the library. It will be created by default. To prevent this, load the
+library as follows::
+
+	$this->load->library('jquery', FALSE);
+
+Once loaded, the jQuery library object will be available using:
+$this->jquery
+
+jQuery Events
+=============
+
+Events are set using the following syntax.
+
+::
+
+	$this->jquery->event('element_path', code_to_run());
+
+
+In the above example:
+
+-  "event" is any of blur, change, click, dblclick, error, focus, hover,
+   keydown, keyup, load, mousedown, mouseup, mouseover, mouseup, resize,
+   scroll, or unload.
+-  "element_path" is any valid `jQuery
+   selector <http://docs.jquery.com/Selectors>`_. Due to jQuery's unique
+   selector syntax, this is usually an element id, or CSS selector. For
+   example "#notice_area" would effect <div id="notice_area">, and
+   "#content a.notice" would effect all anchors with a class of "notice"
+   in the div with id "content".
+-  "code_to_run()" is script your write yourself, or an action such as
+   an effect from the jQuery library below.
+
+Effects
+=======
+
+The query library supports a powerful
+`Effects <http://docs.jquery.com/Effects>`_ repertoire. Before an effect
+can be used, it must be loaded::
+
+	$this->jquery->effect([optional path] plugin name); // for example $this->jquery->effect('bounce');
+
+
+hide() / show()
+---------------
+
+Each of this functions will affect the visibility of an item on your
+page. hide() will set an item invisible, show() will reveal it.
+
+::
+
+	$this->jquery->hide(target,  optional speed, optional extra information);     $this->jquery->show(target,  optional speed, optional extra information);
+
+
+-  "target" will be any valid jQuery selector or selectors.
+-  "speed" is optional, and is set to either slow, normal, fast, or
+   alternatively a number of milliseconds.
+-  "extra information" is optional, and could include a callback, or
+   other additional information.
+
+toggle()
+--------
+
+toggle() will change the visibility of an item to the opposite of its
+current state, hiding visible elements, and revealing hidden ones.
+
+::
+
+	$this->jquery->toggle(target);
+
+
+-  "target" will be any valid jQuery selector or selectors.
+
+animate()
+---------
+
+::
+
+	 $this->jquery->animate(target, parameters, optional speed, optional extra information);
+
+
+-  "target" will be any valid jQuery selector or selectors.
+-  "parameters" in jQuery would generally include a series of CSS
+   properties that you wish to change.
+-  "speed" is optional, and is set to either slow, normal, fast, or
+   alternatively a number of milliseconds.
+-  "extra information" is optional, and could include a callback, or
+   other additional information.
+
+For a full summary, see
+`http://docs.jquery.com/Effects/animate <http://docs.jquery.com/Effects/animate>`_
+
+Here is an example of an animate() called on a div with an id of "note",
+and triggered by a click using the jQuery library's click() event.
+
+::
+
+	 $params = array(     'height' => 80,     'width' => '50%',     'marginLeft' => 125 ); $this->jquery->click('#trigger', $this->jquery->animate('#note', $params, normal));
+
+
+fadeIn() / fadeOut()
+--------------------
+
+::
+
+	$this->jquery->fadeIn(target,  optional speed, optional extra information);     $this->jquery->fadeOut(target,  optional speed, optional extra information);
+
+
+-  "target" will be any valid jQuery selector or selectors.
+-  "speed" is optional, and is set to either slow, normal, fast, or
+   alternatively a number of milliseconds.
+-  "extra information" is optional, and could include a callback, or
+   other additional information.
+
+toggleClass()
+-------------
+
+This function will add or remove a CSS class to its target.
+
+::
+
+	$this->jquery->toggleClass(target, class)
+
+
+-  "target" will be any valid jQuery selector or selectors.
+-  "class" is any CSS classname. Note that this class must be defined
+   and available in a CSS that is already loaded.
+
+fadeIn() / fadeOut()
+--------------------
+
+These effects cause an element(s) to disappear or reappear over time.
+
+::
+
+	$this->jquery->fadeIn(target,  optional speed, optional extra information);     $this->jquery->fadeOut(target,  optional speed, optional extra information);
+
+
+-  "target" will be any valid jQuery selector or selectors.
+-  "speed" is optional, and is set to either slow, normal, fast, or
+   alternatively a number of milliseconds.
+-  "extra information" is optional, and could include a callback, or
+   other additional information.
+
+slideUp() / slideDown() / slideToggle()
+---------------------------------------
+
+These effects cause an element(s) to slide.
+
+::
+
+	$this->jquery->slideUp(target,  optional speed, optional extra information);     $this->jquery->slideDown(target,  optional speed, optional extra information); $this->jquery->slideToggle(target,  optional speed, optional extra information);
+
+
+-  "target" will be any valid jQuery selector or selectors.
+-  "speed" is optional, and is set to either slow, normal, fast, or
+   alternatively a number of milliseconds.
+-  "extra information" is optional, and could include a callback, or
+   other additional information.
+
+Plugins
+=======
+
+Some select jQuery plugins are made available using this library.
+
+corner()
+--------
+
+Used to add distinct corners to page elements. For full details see
+`http://www.malsup.com/jquery/corner/ <http://www.malsup.com/jquery/corner/>`_
+
+::
+
+	$this->jquery->corner(target, corner_style);
+
+
+-  "target" will be any valid jQuery selector or selectors.
+-  "corner_style" is optional, and can be set to any valid style such
+   as round, sharp, bevel, bite, dog, etc. Individual corners can be set
+   by following the style with a space and using "tl" (top left), "tr"
+   (top right), "bl" (bottom left), or "br" (bottom right).

+##############
+Language Class
+##############
+
+The Language Class provides functions to retrieve language files and
+lines of text for purposes of internationalization.
+
+In your CodeIgniter system folder you'll find one called language
+containing sets of language files. You can create your own language
+files as needed in order to display error and other messages in other
+languages.
+
+Language files are typically stored in your system/language directory.
+Alternately you can create a folder called language inside your
+application folder and store them there. CodeIgniter will look first in
+your application/language directory. If the directory does not exist or
+the specified language is not located there CI will instead look in your
+global system/language folder.
+
+.. note:: Each language should be stored in its own folder. For example,
+	the English files are located at: system/language/english
+
+Creating Language Files
+=======================
+
+Language files must be named with _lang.php as the file extension. For
+example, let's say you want to create a file containing error messages.
+You might name it: error_lang.php
+
+Within the file you will assign each line of text to an array called
+$lang with this prototype::
+
+	$lang['language_key'] = "The actual message to be shown";
+
+.. note:: It's a good practice to use a common prefix for all messages
+	in a given file to avoid collisions with similarly named items in other
+	files. For example, if you are creating error messages you might prefix
+	them with error\_
+
+::
+
+	$lang['error_email_missing'] = "You must submit an email address"; $lang['error_url_missing'] = "You must submit a URL"; $lang['error_username_missing'] = "You must submit a username";
+
+Loading A Language File
+=======================
+
+In order to fetch a line from a particular file you must load the file
+first. Loading a language file is done with the following code::
+
+	$this->lang->load('filename', 'language');
+
+Where filename is the name of the file you wish to load (without the
+file extension), and language is the language set containing it (ie,
+english). If the second parameter is missing, the default language set
+in your application/config/config.php file will be used.
+
+Fetching a Line of Text
+=======================
+
+Once your desired language file is loaded you can access any line of
+text using this function::
+
+	$this->lang->line('language_key');
+
+Where language_key is the array key corresponding to the line you wish
+to show.
+
+Note: This function simply returns the line. It does not echo it for
+you.
+
+Using language lines as form labels
+-----------------------------------
+
+This feature has been deprecated from the language library and moved to
+the lang() function of the :doc:`Language
+helper <../helpers/language_helper>`.
+
+Auto-loading Languages
+======================
+
+If you find that you need a particular language globally throughout your
+application, you can tell CodeIgniter to
+:doc:`auto-load <../general/autoloader>` it during system
+initialization. This is done by opening the
+application/config/autoload.php file and adding the language(s) to the
+autoload array.

+############
+Loader Class
+############
+
+Loader, as the name suggests, is used to load elements. These elements
+can be libraries (classes) :doc:`View files <../general/views>`,
+:doc:`Helpers <../general/helpers>`,
+:doc:`Models <../general/models>`, or your own files.
+
+.. note:: This class is initialized automatically by the system so there
+	is no need to do it manually.
+
+The following functions are available in this class:
+
+$this->load->library('class_name', $config, 'object name')
+===========================================================
+
+This function is used to load core classes. Where class_name is the
+name of the class you want to load. Note: We use the terms "class" and
+"library" interchangeably.
+
+For example, if you would like to send email with CodeIgniter, the first
+step is to load the email class within your controller::
+
+	$this->load->library('email');
+
+Once loaded, the library will be ready for use, using
+$this->email->*some_function*().
+
+Library files can be stored in subdirectories within the main
+"libraries" folder, or within your personal application/libraries
+folder. To load a file located in a subdirectory, simply include the
+path, relative to the "libraries" folder. For example, if you have file
+located at::
+
+	libraries/flavors/chocolate.php
+
+You will load it using::
+
+	$this->load->library('flavors/chocolate');
+
+You may nest the file in as many subdirectories as you want.
+
+Additionally, multiple libraries can be loaded at the same time by
+passing an array of libraries to the load function.
+
+::
+
+	$this->load->library(array('email', 'table'));
+
+Setting options
+---------------
+
+The second (optional) parameter allows you to optionally pass
+configuration setting. You will typically pass these as an array::
+
+	 $config = array (                   'mailtype' => 'html',                   'charset'  => 'utf-8,                   'priority' => '1'                );  $this->load->library('email', $config);
+
+Config options can usually also be set via a config file. Each library
+is explained in detail in its own page, so please read the information
+regarding each one you would like to use.
+
+Please take note, when multiple libraries are supplied in an array for
+the first parameter, each will receive the same parameter information.
+
+Assigning a Library to a different object name
+----------------------------------------------
+
+If the third (optional) parameter is blank, the library will usually be
+assigned to an object with the same name as the library. For example, if
+the library is named Session, it will be assigned to a variable named
+$this->session.
+
+If you prefer to set your own class names you can pass its value to the
+third parameter::
+
+	$this->load->library('session', '', 'my_session');  // Session class is now accessed using:  $this->my_session 
+
+Please take note, when multiple libraries are supplied in an array for
+the first parameter, this parameter is discarded.
+
+$this->load->view('file_name', $data, true/false)
+==================================================
+
+This function is used to load your View files. If you haven't read the
+:doc:`Views <../general/views>` section of the user guide it is
+recommended that you do since it shows you how this function is
+typically used.
+
+The first parameter is required. It is the name of the view file you
+would like to load. Note: The .php file extension does not need to be
+specified unless you use something other than .php.
+
+The second **optional** parameter can take an associative array or an
+object as input, which it runs through the PHP
+`extract <http://www.php.net/extract>`_ function to convert to variables
+that can be used in your view files. Again, read the
+:doc:`Views <../general/views>` page to learn how this might be useful.
+
+The third **optional** parameter lets you change the behavior of the
+function so that it returns data as a string rather than sending it to
+your browser. This can be useful if you want to process the data in some
+way. If you set the parameter to true (boolean) it will return data. The
+default behavior is false, which sends it to your browser. Remember to
+assign it to a variable if you want the data returned::
+
+	$string = $this->load->view('myfile', '', true);
+
+$this->load->model('Model_name');
+==================================
+
+::
+
+	$this->load->model('Model_name');
+
+
+If your model is located in a sub-folder, include the relative path from
+your models folder. For example, if you have a model located at
+application/models/blog/queries.php you'll load it using::
+
+	$this->load->model('blog/queries');
+
+
+If you would like your model assigned to a different object name you can
+specify it via the second parameter of the loading function::
+
+	 $this->load->model('Model_name', 'fubar');  $this->fubar->function();
+
+$this->load->database('options', true/false)
+============================================
+
+This function lets you load the database class. The two parameters are
+**optional**. Please see the :doc:`database <../database/index>`
+section for more info.
+
+$this->load->vars($array)
+=========================
+
+This function takes an associative array as input and generates
+variables using the PHP `extract <http://www.php.net/extract>`_
+function. This function produces the same result as using the second
+parameter of the $this->load->view() function above. The reason you
+might want to use this function independently is if you would like to
+set some global variables in the constructor of your controller and have
+them become available in any view file loaded from any function. You can
+have multiple calls to this function. The data get cached and merged
+into one array for conversion to variables.
+
+$this->load->get_var($key)
+===========================
+
+This function checks the associative array of variables available to
+your views. This is useful if for any reason a var is set in a library
+or another controller method using $this->load->vars().
+
+$this->load->helper('file_name')
+=================================
+
+This function loads helper files, where file_name is the name of the
+file, without the _helper.php extension.
+
+$this->load->file('filepath/filename', true/false)
+==================================================
+
+This is a generic file loading function. Supply the filepath and name in
+the first parameter and it will open and read the file. By default the
+data is sent to your browser, just like a View file, but if you set the
+second parameter to true (boolean) it will instead return the data as a
+string.
+
+$this->load->language('file_name')
+===================================
+
+This function is an alias of the :doc:`language loading
+function <language>`: $this->lang->load()
+
+$this->load->config('file_name')
+=================================
+
+This function is an alias of the :doc:`config file loading
+function <config>`: $this->config->load()
+
+Application "Packages"
+======================
+
+An application package allows for the easy distribution of complete sets
+of resources in a single directory, complete with its own libraries,
+models, helpers, config, and language files. It is recommended that
+these packages be placed in the application/third_party folder. Below
+is a sample map of an package directory
+
+Sample Package "Foo Bar" Directory Map
+======================================
+
+The following is an example of a directory for an application package
+named "Foo Bar".
+
+::
+
+	/application/third_party/foo_bar  config/ helpers/ language/ libraries/ models/
+
+Whatever the purpose of the "Foo Bar" application package, it has its
+own config files, helpers, language files, libraries, and models. To use
+these resources in your controllers, you first need to tell the Loader
+that you are going to be loading resources from a package, by adding the
+package path.
+
+$this->load->add_package_path()
+---------------------------------
+
+Adding a package path instructs the Loader class to prepend a given path
+for subsequent requests for resources. As an example, the "Foo Bar"
+application package above has a library named Foo_bar.php. In our
+controller, we'd do the following::
+
+	$this->load->add_package_path(APPPATH.'third_party/foo_bar/'); $this->load->library('foo_bar');
+
+$this->load->remove_package_path()
+------------------------------------
+
+When your controller is finished using resources from an application
+package, and particularly if you have other application packages you
+want to work with, you may wish to remove the package path so the Loader
+no longer looks in that folder for resources. To remove the last path
+added, simply call the method with no parameters.
+
+$this->load->remove_package_path()
+------------------------------------
+
+Or to remove a specific package path, specify the same path previously
+given to add_package_path() for a package.::
+
+	$this->load->remove_package_path(APPPATH.'third_party/foo_bar/');
+
+Package view files
+------------------
+
+By Default, package view files paths are set when add_package_path()
+is called. View paths are looped through, and once a match is
+encountered that view is loaded.
+
+In this instance, it is possible for view naming collisions within
+packages to occur, and possibly the incorrect package being loaded. To
+ensure against this, set an optional second parameter of FALSE when
+calling add_package_path().
+
+::
+
+	$this->load->add_package_path(APPPATH.'my_app', FALSE);
+	$this->load->view('my_app_index'); // Loads
+	$this->load->view('welcome_message'); // Will not load the default welcome_message b/c the second param to add_package_path is FALSE
+
+	// Reset things
+	$this->load->remove_package_path(APPPATH.'my_app');
+
+	// Again without the second parameter:
+	$this->load->add_package_path(APPPATH.'my_app', TRUE);
+	$this->load->view('my_app_index'); // Loads
+	$this->load->view('welcome_message'); // Loads

+############
+Output Class
+############
+
+The Output class is a small class with one main function: To send the
+finalized web page to the requesting browser. It is also responsible for
+:doc:`caching <../general/caching>` your web pages, if you use that
+feature.
+
+.. note:: This class is initialized automatically by the system so there
+	is no need to do it manually.
+
+Under normal circumstances you won't even notice the Output class since
+it works transparently without your intervention. For example, when you
+use the :doc:`Loader <../libraries/loader>` class to load a view file,
+it's automatically passed to the Output class, which will be called
+automatically by CodeIgniter at the end of system execution. It is
+possible, however, for you to manually intervene with the output if you
+need to, using either of the two following functions:
+
+$this->output->set_output();
+=============================
+
+Permits you to manually set the final output string. Usage example::
+
+	$this->output->set_output($data);
+
+.. important:: If you do set your output manually, it must be the last
+	thing done in the function you call it from. For example, if you build a
+	page in one of your controller functions, don't set the output until the
+	end.
+
+$this->output->set_content_type();
+====================================
+
+Permits you to set the mime-type of your page so you can serve JSON
+data, JPEG's, XML, etc easily.
+
+::
+
+	$this->output
+	    ->set_content_type('application/json')
+	    ->set_output(json_encode(array('foo' => 'bar')));
+
+	$this->output
+	    ->set_content_type('jpeg') // You could also use ".jpeg" which will have the full stop removed before looking in config/mimes.php
+	    ->set_output(file_get_contents('files/something.jpg'));
+
+.. important:: Make sure any non-mime string you pass to this method
+	exists in config/mimes.php or it will have no effect.
+
+$this->output->get_output();
+=============================
+
+Permits you to manually retrieve any output that has been sent for
+storage in the output class. Usage example::
+
+	$string = $this->output->get_output();
+
+Note that data will only be retrievable from this function if it has
+been previously sent to the output class by one of the CodeIgniter
+functions like $this->load->view().
+
+$this->output->append_output();
+================================
+
+Appends data onto the output string. Usage example::
+
+	$this->output->append_output($data);
+
+$this->output->set_header();
+=============================
+
+Permits you to manually set server headers, which the output class will
+send for you when outputting the final rendered display. Example::
+
+	 $this->output->set_header("HTTP/1.0 200 OK"); $this->output->set_header("HTTP/1.1 200 OK"); $this->output->set_header('Last-Modified: '.gmdate('D, d M Y H:i:s', $last_update).' GMT'); $this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate"); $this->output->set_header("Cache-Control: post-check=0, pre-check=0"); $this->output->set_header("Pragma: no-cache");  
+
+$this->output->set_status_header(code, 'text');
+=================================================
+
+Permits you to manually set a server status header. Example::
+
+	$this->output->set_status_header('401'); // Sets the header as:  Unauthorized
+
+`See here <http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html>`_ for
+a full list of headers.
+
+$this->output->enable_profiler();
+==================================
+
+Permits you to enable/disable the
+:doc:`Profiler <../general/profiling>`, which will display benchmark
+and other data at the bottom of your pages for debugging and
+optimization purposes.
+
+To enable the profiler place the following function anywhere within your
+:doc:`Controller <../general/controllers>` functions::
+
+	$this->output->enable_profiler(TRUE);
+
+When enabled a report will be generated and inserted at the bottom of
+your pages.
+
+To disable the profiler you will use::
+
+	$this->output->enable_profiler(FALSE);
+
+$this->output->set_profiler_sections();
+=========================================
+
+Permits you to enable/disable specific sections of the Profiler when
+enabled. Please refer to the :doc:`Profiler <../general/profiling>`
+documentation for further information.
+
+$this->output->cache();
+=======================
+
+The CodeIgniter output library also controls caching. For more
+information, please see the :doc:`caching
+documentation <../general/caching>`.
+
+Parsing Execution Variables
+===========================
+
+CodeIgniter will parse the pseudo-variables {elapsed_time} and
+{memory_usage} in your output by default. To disable this, set the
+$parse_exec_vars class property to FALSE in your controller.
+::
+
+	$this->output->parse_exec_vars = FALSE;

+################
+Pagination Class
+################
+
+CodeIgniter's Pagination class is very easy to use, and it is 100%
+customizable, either dynamically or via stored preferences.
+
+If you are not familiar with the term "pagination", it refers to links
+that allows you to navigate from page to page, like this::
+
+	« First  < 1 2 3 4 5 >  Last »
+
+*******
+Example
+*******
+
+Here is a simple example showing how to create pagination in one of your
+:doc:`controller <../general/controllers>` functions::
+
+	 $this->load->library('pagination'); $config['base_url'] = 'http://example.com/index.php/test/page/'; $config['total_rows'] = 200; $config['per_page']  = 20;  $this->pagination->initialize($config);   echo  $this->pagination->create_links();
+
+Notes
+=====
+
+The $config array contains your configuration variables. It is passed to
+the $this->pagination->initialize function as shown above. Although
+there are some twenty items you can configure, at minimum you need the
+three shown. Here is a description of what those items represent:
+
+-  **base_url** This is the full URL to the controller class/function
+   containing your pagination. In the example above, it is pointing to a
+   controller called "Test" and a function called "page". Keep in mind
+   that you can :doc:`re-route your URI <../general/routing>` if you
+   need a different structure.
+-  **total_rows** This number represents the total rows in the result
+   set you are creating pagination for. Typically this number will be
+   the total rows that your database query returned.
+-  **per_page** The number of items you intend to show per page. In the
+   above example, you would be showing 20 items per page.
+
+The create_links() function returns an empty string when there is no
+pagination to show.
+
+Setting preferences in a config file
+====================================
+
+If you prefer not to set preferences using the above method, you can
+instead put them into a config file. Simply create a new file called
+pagination.php, add the $config array in that file. Then save the file
+in: config/pagination.php and it will be used automatically. You will
+NOT need to use the $this->pagination->initialize function if you save
+your preferences in a config file.
+
+**************************
+Customizing the Pagination
+**************************
+
+The following is a list of all the preferences you can pass to the
+initialization function to tailor the display.
+
+$config['uri_segment'] = 3;
+============================
+
+The pagination function automatically determines which segment of your
+URI contains the page number. If you need something different you can
+specify it.
+
+$config['num_links'] = 2;
+==========================
+
+The number of "digit" links you would like before and after the selected
+page number. For example, the number 2 will place two digits on either
+side, as in the example links at the very top of this page.
+
+$config['use_page_number'] = TRUE;
+==================================
+
+By default, the URI segment will use the starting index for the items
+you are paginating. If you prefer to show the the actual page number,
+set this to TRUE.
+
+$config['page_query_string'] = TRUE;
+====================================
+
+By default, the pagination library assume you are using :doc:`URI
+Segments <../general/urls>`, and constructs your links something
+like
+
+::
+
+	http://example.com/index.php/test/page/20
+
+
+If you have $config['enable_query_strings'] set to TRUE your links
+will automatically be re-written using Query Strings. This option can
+also be explictly set. Using $config['page_query_string'] set to TRUE,
+the pagination link will become.
+
+::
+
+	http://example.com/index.php?c=test&m=page&per_page=20
+
+
+Note that "per_page" is the default query string passed, however can be
+configured using $config['query_string_segment'] = 'your_string'
+
+***********************
+Adding Enclosing Markup
+***********************
+
+If you would like to surround the entire pagination with some markup you
+can do it with these two prefs:
+
+$config['full_tag_open'] = '<p>';
+===================================
+
+The opening tag placed on the left side of the entire result.
+
+$config['full_tag_close'] = '</p>';
+=====================================
+
+The closing tag placed on the right side of the entire result.
+
+**************************
+Customizing the First Link
+**************************
+
+$config['first_link'] = 'First';
+=================================
+
+The text you would like shown in the "first" link on the left. If you do
+not want this link rendered, you can set its value to FALSE.
+
+$config['first_tag_open'] = '<div>';
+======================================
+
+The opening tag for the "first" link.
+
+$config['first_tag_close'] = '</div>';
+========================================
+
+The closing tag for the "first" link.
+
+*************************
+Customizing the Last Link
+*************************
+
+$config['last_link'] = 'Last';
+===============================
+
+The text you would like shown in the "last" link on the right. If you do
+not want this link rendered, you can set its value to FALSE.
+
+$config['last_tag_open'] = '<div>';
+=====================================
+
+The opening tag for the "last" link.
+
+$config['last_tag_close'] = '</div>';
+=======================================
+
+The closing tag for the "last" link.
+
+***************************
+Customizing the "Next" Link
+***************************
+
+$config['next_link'] = '&gt;';
+===============================
+
+The text you would like shown in the "next" page link. If you do not
+want this link rendered, you can set its value to FALSE.
+
+$config['next_tag_open'] = '<div>';
+=====================================
+
+The opening tag for the "next" link.
+
+$config['next_tag_close'] = '</div>';
+=======================================
+
+The closing tag for the "next" link.
+
+*******************************
+Customizing the "Previous" Link
+*******************************
+
+$config['prev_link'] = '&lt;';
+===============================
+
+The text you would like shown in the "previous" page link. If you do not
+want this link rendered, you can set its value to FALSE.
+
+$config['prev_tag_open'] = '<div>';
+=====================================
+
+The opening tag for the "previous" link.
+
+$config['prev_tag_close'] = '</div>';
+=======================================
+
+The closing tag for the "previous" link.
+
+***********************************
+Customizing the "Current Page" Link
+***********************************
+
+$config['cur_tag_open'] = '<b>';
+==================================
+
+The opening tag for the "current" link.
+
+$config['cur_tag_close'] = '</b>';
+====================================
+
+The closing tag for the "current" link.
+
+****************************
+Customizing the "Digit" Link
+****************************
+
+$config['num_tag_open'] = '<div>';
+====================================
+
+The opening tag for the "digit" link.
+
+$config['num_tag_close'] = '</div>';
+======================================
+
+The closing tag for the "digit" link.
+
+****************
+Hiding the Pages
+****************
+
+If you wanted to not list the specific pages (for example, you only want
+"next" and "previous" links), you can suppress their rendering by
+adding::
+
+	 $config['display_pages'] = FALSE;
+
+******************************
+Adding a class to every anchor
+******************************
+
+If you want to add a class attribute to every link rendered by the
+pagination class, you can set the config "anchor_class" equal to the
+classname you want.

+#####################
+Template Parser Class
+#####################
+
+The Template Parser Class enables you to parse pseudo-variables
+contained within your view files. It can parse simple variables or
+variable tag pairs. If you've never used a template engine,
+pseudo-variables look like this::
+
+	<html> <head> <title>{blog_title}</title> </head> <body>  <h3>{blog_heading}</h3>  {blog_entries} <h5>{title}</h5> <p>{body}</p> {/blog_entries}  </body> </html>
+
+These variables are not actual PHP variables, but rather plain text
+representations that allow you to eliminate PHP from your templates
+(view files).
+
+.. note:: CodeIgniter does **not** require you to use this class since
+	using pure PHP in your view pages lets them run a little faster.
+	However, some developers prefer to use a template engine if they work
+	with designers who they feel would find some confusion working with PHP.
+
+.. important:: The Template Parser Class is **not** a full-blown
+	template parsing solution. We've kept it very lean on purpose in order
+	to maintain maximum performance.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Parser class is initialized
+in your controller using the $this->load->library function::
+
+	$this->load->library('parser');
+
+Once loaded, the Parser library object will be available using:
+$this->parser
+
+The following functions are available in this library:
+
+$this->parser->parse()
+======================
+
+This method accepts a template name and data array as input, and it
+generates a parsed version. Example::
+
+	$this->load->library('parser');  $data = array(             'blog_title' => 'My Blog Title',             'blog_heading' => 'My Blog Heading'             );  $this->parser->parse('blog_template', $data);
+
+The first parameter contains the name of the :doc:`view
+file <../general/views>` (in this example the file would be called
+blog_template.php), and the second parameter contains an associative
+array of data to be replaced in the template. In the above example, the
+template would contain two variables: {blog_title} and {blog_heading}
+
+There is no need to "echo" or do something with the data returned by
+$this->parser->parse(). It is automatically passed to the output class
+to be sent to the browser. However, if you do want the data returned
+instead of sent to the output class you can pass TRUE (boolean) to the
+third parameter::
+
+	$string = $this->parser->parse('blog_template', $data, TRUE);
+
+$this->parser->parse_string()
+==============================
+
+This method works exactly like parse(), only accepts a string as the
+first parameter in place of a view file.
+
+Variable Pairs
+==============
+
+The above example code allows simple variables to be replaced. What if
+you would like an entire block of variables to be repeated, with each
+iteration containing new values? Consider the template example we showed
+at the top of the page::
+
+	<html> <head> <title>{blog_title}</title> </head> <body>  <h3>{blog_heading}</h3>  {blog_entries} <h5>{title}</h5> <p>{body}</p> {/blog_entries}  </body> </html>
+
+In the above code you'll notice a pair of variables: {blog_entries}
+data... {/blog_entries}. In a case like this, the entire chunk of data
+between these pairs would be repeated multiple times, corresponding to
+the number of rows in a result.
+
+Parsing variable pairs is done using the identical code shown above to
+parse single variables, except, you will add a multi-dimensional array
+corresponding to your variable pair data. Consider this example::
+
+	$this->load->library('parser');  $data = array(               'blog_title'   => 'My Blog Title',               'blog_heading' => 'My Blog Heading',               'blog_entries' => array(                                       array('title' => 'Title 1', 'body' => 'Body 1'),                                       array('title' => 'Title 2', 'body' => 'Body 2'),                                       array('title' => 'Title 3', 'body' => 'Body 3'),                                       array('title' => 'Title 4', 'body' => 'Body 4'),                                       array('title' => 'Title 5', 'body' => 'Body 5')                                       )             );  $this->parser->parse('blog_template', $data);
+
+If your "pair" data is coming from a database result, which is already a
+multi-dimensional array, you can simply use the database result_array()
+function::
+
+	 $query = $this->db->query("SELECT * FROM blog");  $this->load->library('parser');  $data = array(               'blog_title'   => 'My Blog Title',               'blog_heading' => 'My Blog Heading',               'blog_entries' => $query->result_array()             );  $this->parser->parse('blog_template', $data);
+

+##############
+Security Class
+##############
+
+The Security Class contains methods that help you create a secure
+application, processing input data for security.
+
+XSS Filtering
+=============
+
+CodeIgniter comes with a Cross Site Scripting Hack prevention filter
+which can either run automatically to filter all POST and COOKIE data
+that is encountered, or you can run it on a per item basis. By default
+it does **not** run globally since it requires a bit of processing
+overhead, and since you may not need it in all cases.
+
+The XSS filter looks for commonly used techniques to trigger Javascript
+or other types of code that attempt to hijack cookies or do other
+malicious things. If anything disallowed is encountered it is rendered
+safe by converting the data to character entities.
+
+Note: This function should only be used to deal with data upon
+submission. It's not something that should be used for general runtime
+processing since it requires a fair amount of processing overhead.
+
+To filter data through the XSS filter use this function:
+
+$this->security->xss_clean()
+=============================
+
+Here is an usage example::
+
+	$data = $this->security->xss_clean($data);
+
+If you want the filter to run automatically every time it encounters
+POST or COOKIE data you can enable it by opening your
+application/config/config.php file and setting this::
+
+	$config['global_xss_filtering'] = TRUE;
+
+Note: If you use the form validation class, it gives you the option of
+XSS filtering as well.
+
+An optional second parameter, is_image, allows this function to be used
+to test images for potential XSS attacks, useful for file upload
+security. When this second parameter is set to TRUE, instead of
+returning an altered string, the function returns TRUE if the image is
+safe, and FALSE if it contained potentially malicious information that a
+browser may attempt to execute.
+
+::
+
+	if ($this->security->xss_clean($file, TRUE) === FALSE) {     // file failed the XSS test }
+
+$this->security->sanitize_filename()
+=====================================
+
+When accepting filenames from user input, it is best to sanitize them to
+prevent directory traversal and other security related issues. To do so,
+use the sanitize_filename() method of the Security class. Here is an
+example::
+
+	$filename = $this->security->sanitize_filename($this->input->post('filename'));
+
+If it is acceptable for the user input to include relative paths, e.g.
+file/in/some/approved/folder.txt, you can set the second optional
+parameter, $relative_path to TRUE.
+
+::
+
+	$filename = $this->security->sanitize_filename($this->input->post('filename'), TRUE);
+
+Cross-site request forgery (CSRF)
+=================================
+
+You can enable csrf protection by opening your
+application/config/config.php file and setting this::
+
+	$config['csrf_protection'] = TRUE;
+
+If you use the :doc:`form helper <../helpers/form_helper>` the
+form_open() function will automatically insert a hidden csrf field in
+your forms.
+
+Select URIs can be whitelisted from csrf protection (for example API
+endpoints expecting externally POSTed content). You can add these URIs
+by editing the 'csrf_exclude_uris' config parameter::
+
+	$config['csrf_exclude_uris'] = array('api/person/add');

+#############
+Session Class
+#############
+
+The Session class permits you maintain a user's "state" and track their
+activity while they browse your site. The Session class stores session
+information for each user as serialized (and optionally encrypted) data
+in a cookie. It can also store the session data in a database table for
+added security, as this permits the session ID in the user's cookie to
+be matched against the stored session ID. By default only the cookie is
+saved. If you choose to use the database option you'll need to create
+the session table as indicated below.
+
+.. note:: The Session class does **not** utilize native PHP sessions. It
+	generates its own session data, offering more flexibility for
+	developers.
+
+.. note:: Even if you are not using encrypted sessions, you must set
+	an :doc:`encryption key <./encryption>` in your config file which is used
+	to aid in preventing session data manipulation.
+
+Initializing a Session
+======================
+
+Sessions will typically run globally with each page load, so the session
+class must either be :doc:`initialized <../general/libraries>` in your
+:doc:`controller <../general/controllers>` constructors, or it can be
+:doc:`auto-loaded <../general/autoloader>` by the system. For the most
+part the session class will run unattended in the background, so simply
+initializing the class will cause it to read, create, and update
+sessions.
+
+To initialize the Session class manually in your controller constructor,
+use the $this->load->library function::
+
+	$this->load->library('session');
+
+Once loaded, the Sessions library object will be available using:
+$this->session
+
+How do Sessions work?
+=====================
+
+When a page is loaded, the session class will check to see if valid
+session data exists in the user's session cookie. If sessions data does
+**not** exist (or if it has expired) a new session will be created and
+saved in the cookie. If a session does exist, its information will be
+updated and the cookie will be updated. With each update, the
+session_id will be regenerated.
+
+It's important for you to understand that once initialized, the Session
+class runs automatically. There is nothing you need to do to cause the
+above behavior to happen. You can, as you'll see below, work with
+session data or even add your own data to a user's session, but the
+process of reading, writing, and updating a session is automatic.
+
+What is Session Data?
+=====================
+
+A *session*, as far as CodeIgniter is concerned, is simply an array
+containing the following information:
+
+-  The user's unique Session ID (this is a statistically random string
+   with very strong entropy, hashed with MD5 for portability, and
+   regenerated (by default) every five minutes)
+-  The user's IP Address
+-  The user's User Agent data (the first 120 characters of the browser
+   data string)
+-  The "last activity" time stamp.
+
+The above data is stored in a cookie as a serialized array with this
+prototype::
+
+	[array] (      'session_id'    => random hash,      'ip_address'    => 'string - user IP address',      'user_agent'    => 'string - user agent data',      'last_activity' => timestamp )
+
+If you have the encryption option enabled, the serialized array will be
+encrypted before being stored in the cookie, making the data highly
+secure and impervious to being read or altered by someone. More info
+regarding encryption can be :doc:`found here <encryption>`, although
+the Session class will take care of initializing and encrypting the data
+automatically.
+
+Note: Session cookies are only updated every five minutes by default to
+reduce processor load. If you repeatedly reload a page you'll notice
+that the "last activity" time only updates if five minutes or more has
+passed since the last time the cookie was written. This time is
+configurable by changing the $config['sess_time_to_update'] line in
+your system/config/config.php file.
+
+Retrieving Session Data
+=======================
+
+Any piece of information from the session array is available using the
+following function::
+
+	$this->session->userdata('item');
+
+Where item is the array index corresponding to the item you wish to
+fetch. For example, to fetch the session ID you will do this::
+
+	$session_id = $this->session->userdata('session_id');
+
+.. note:: The function returns FALSE (boolean) if the item you are
+	trying to access does not exist.
+
+Adding Custom Session Data
+==========================
+
+A useful aspect of the session array is that you can add your own data
+to it and it will be stored in the user's cookie. Why would you want to
+do this? Here's one example:
+
+Let's say a particular user logs into your site. Once authenticated, you
+could add their username and email address to the session cookie, making
+that data globally available to you without having to run a database
+query when you need it.
+
+To add your data to the session array involves passing an array
+containing your new data to this function::
+
+	$this->session->set_userdata($array);
+
+Where $array is an associative array containing your new data. Here's an
+example::
+
+	$newdata = array(                        'username'  => 'johndoe',                        'email'     => 'johndoe@some-site.com',                        'logged_in' => TRUE                    );          $this->session->set_userdata($newdata);
+
+
+If you want to add userdata one value at a time, set_userdata() also
+supports this syntax.
+
+::
+
+	$this->session->set_userdata('some_name', 'some_value');
+
+
+.. note:: Cookies can only hold 4KB of data, so be careful not to exceed
+	the capacity. The encryption process in particular produces a longer
+	data string than the original so keep careful track of how much data you
+	are storing.
+
+Retrieving All Session Data
+===========================
+
+An array of all userdata can be retrieved as follows::
+
+	$this->session->all_userdata()
+
+And returns an associative array like the following::
+
+
+    Array
+    (
+        [session_id] => 4a5a5dca22728fb0a84364eeb405b601
+        [ip_address] => 127.0.0.1
+        [user_agent] => Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_7;
+        [last_activity] => 1303142623
+    )
+
+Removing Session Data
+=====================
+
+Just as set_userdata() can be used to add information into a session,
+unset_userdata() can be used to remove it, by passing the session key.
+For example, if you wanted to remove 'some_name' from your session
+information::
+
+	$this->session->unset_userdata('some_name');
+
+
+This function can also be passed an associative array of items to unset.
+
+::
+
+	$array_items = array('username' => '', 'email' => '');  $this->session->unset_userdata($array_items);
+
+
+Flashdata
+=========
+
+CodeIgniter supports "flashdata", or session data that will only be
+available for the next server request, and are then automatically
+cleared. These can be very useful, and are typically used for
+informational or status messages (for example: "record 2 deleted").
+
+Note: Flash variables are prefaced with "flash\_" so avoid this prefix
+in your own session names.
+
+To add flashdata::
+
+	$this->session->set_flashdata('item', 'value');
+
+
+You can also pass an array to set_flashdata(), in the same manner as
+set_userdata().
+
+To read a flashdata variable::
+
+	$this->session->flashdata('item');
+
+
+If you find that you need to preserve a flashdata variable through an
+additional request, you can do so using the keep_flashdata() function.
+
+::
+
+	$this->session->keep_flashdata('item');
+
+
+Saving Session Data to a Database
+=================================
+
+While the session data array stored in the user's cookie contains a
+Session ID, unless you store session data in a database there is no way
+to validate it. For some applications that require little or no
+security, session ID validation may not be needed, but if your
+application requires security, validation is mandatory. Otherwise, an
+old session could be restored by a user modifying their cookies.
+
+When session data is available in a database, every time a valid session
+is found in the user's cookie, a database query is performed to match
+it. If the session ID does not match, the session is destroyed. Session
+IDs can never be updated, they can only be generated when a new session
+is created.
+
+In order to store sessions, you must first create a database table for
+this purpose. Here is the basic prototype (for MySQL) required by the
+session class:
+
+CREATE TABLE IF NOT EXISTS \`ci_sessions\` ( session_id varchar(40)
+DEFAULT '0' NOT NULL, ip_address varchar(16) DEFAULT '0' NOT NULL,
+user_agent varchar(120) NOT NULL, last_activity int(10) unsigned
+DEFAULT 0 NOT NULL, user_data text NOT NULL, PRIMARY KEY (session_id),
+KEY \`last_activity_idx\` (\`last_activity\`) );
+
+.. note:: By default the table is called ci_sessions, but you can name
+	it anything you want as long as you update the
+	application/config/config.php file so that it contains the name you have
+	chosen. Once you have created your database table you can enable the
+	database option in your config.php file as follows::
+
+		$config['sess_use_database'] = TRUE;
+
+	Once enabled, the Session class will store session data in the DB.
+
+	Make sure you've specified the table name in your config file as well::
+
+		$config['sess_table_name'] = 'ci_sessions';
+
+.. note:: The Session class has built-in garbage collection which clears
+	out expired sessions so you do not need to write your own routine to do
+	it.
+
+Destroying a Session
+====================
+
+To clear the current session::
+
+	$this->session->sess_destroy();
+
+.. note:: This function should be the last one called, and even flash
+	variables will no longer be available. If you only want some items
+	destroyed and not all, use unset_userdata().
+
+Session Preferences
+===================
+
+You'll find the following Session related preferences in your
+application/config/config.php file:
+
+Preference
+Default
+Options
+Description
+**sess_cookie_name**
+ci_session
+None
+The name you want the session cookie saved as.
+**sess_expiration**
+7200
+None
+The number of seconds you would like the session to last. The default
+value is 2 hours (7200 seconds). If you would like a non-expiring
+session set the value to zero: 0
+**sess_expire_on_close**
+FALSE
+TRUE/FALSE (boolean)
+Whether to cause the session to expire automatically when the browser
+window is closed.
+**sess_encrypt_cookie**
+FALSE
+TRUE/FALSE (boolean)
+Whether to encrypt the session data.
+**sess_use_database**
+FALSE
+TRUE/FALSE (boolean)
+Whether to save the session data to a database. You must create the
+table before enabling this option.
+**sess_table_name**
+ci_sessions
+Any valid SQL table name
+The name of the session database table.
+**sess_time_to_update**
+300
+Time in seconds
+This options controls how often the session class will regenerate itself
+and create a new session id.
+**sess_match_ip**
+FALSE
+TRUE/FALSE (boolean)
+Whether to match the user's IP address when reading the session data.
+Note that some ISPs dynamically changes the IP, so if you want a
+non-expiring session you will likely set this to FALSE.
+**sess_match_useragent**
+TRUE
+TRUE/FALSE (boolean)
+Whether to match the User Agent when reading the session data.

+################
+HTML Table Class
+################
+
+The Table Class provides functions that enable you to auto-generate HTML
+tables from arrays or database result sets.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Table class is initialized
+in your controller using the $this->load->library function::
+
+	$this->load->library('table');
+
+Once loaded, the Table library object will be available using:
+$this->table
+
+Examples
+========
+
+Here is an example showing how you can create a table from a
+multi-dimensional array. Note that the first array index will become the
+table heading (or you can set your own headings using the set_heading()
+function described in the function reference below).
+
+::
+
+	 $this->load->library('table');  $data = array(              array('Name', 'Color', 'Size'),              array('Fred', 'Blue', 'Small'),              array('Mary', 'Red', 'Large'),              array('John', 'Green', 'Medium')                );  echo $this->table->generate($data);
+
+Here is an example of a table created from a database query result. The
+table class will automatically generate the headings based on the table
+names (or you can set your own headings using the set_heading()
+function described in the function reference below).
+
+::
+
+	 $this->load->library('table');  $query = $this->db->query("SELECT * FROM my_table");  echo $this->table->generate($query);
+
+Here is an example showing how you might create a table using discrete
+parameters::
+
+	 $this->load->library('table');  $this->table->set_heading('Name', 'Color', 'Size');  $this->table->add_row('Fred', 'Blue', 'Small'); $this->table->add_row('Mary', 'Red', 'Large'); $this->table->add_row('John', 'Green', 'Medium');  echo $this->table->generate();
+
+Here is the same example, except instead of individual parameters,
+arrays are used::
+
+	 $this->load->library('table');  $this->table->set_heading(array('Name', 'Color', 'Size'));  $this->table->add_row(array('Fred', 'Blue', 'Small')); $this->table->add_row(array('Mary', 'Red', 'Large')); $this->table->add_row(array('John', 'Green', 'Medium'));  echo $this->table->generate();
+
+Changing the Look of Your Table
+===============================
+
+The Table Class permits you to set a table template with which you can
+specify the design of your layout. Here is the template prototype::
+
+	 $tmpl =  array (                     'table_open'          => '<table border="0" cellpadding="4" cellspacing="0">',                      'heading_row_start'   => '<tr>',                     'heading_row_end'     => '</tr>',                     'heading_cell_start'  => '<th>',                     'heading_cell_end'    => '</th>',                      'row_start'           => '<tr>',                     'row_end'             => '</tr>',                     'cell_start'          => '<td>',                     'cell_end'            => '</td>',                      'row_alt_start'       => '<tr>',                     'row_alt_end'         => '</tr>',                     'cell_alt_start'      => '<td>',                     'cell_alt_end'        => '</td>',                      'table_close'         => '</table>'               );   $this->table->set_template($tmpl);
+
+.. note:: You'll notice there are two sets of "row" blocks in the
+	template. These permit you to create alternating row colors or design
+	elements that alternate with each iteration of the row data.
+
+You are NOT required to submit a complete template. If you only need to
+change parts of the layout you can simply submit those elements. In this
+example, only the table opening tag is being changed::
+
+	 $tmpl =  array ( 'table_open'  => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">' );   $this->table->set_template($tmpl);
+
+******************
+Function Reference
+******************
+
+$this->table->generate()
+========================
+
+Returns a string containing the generated table. Accepts an optional
+parameter which can be an array or a database result object.
+
+$this->table->set_caption()
+============================
+
+Permits you to add a caption to the table.
+
+::
+
+	$this->table->set_caption('Colors');
+
+$this->table->set_heading()
+============================
+
+Permits you to set the table heading. You can submit an array or
+discrete params::
+
+	$this->table->set_heading('Name', 'Color', 'Size');
+
+::
+
+	$this->table->set_heading(array('Name', 'Color', 'Size'));
+
+$this->table->add_row()
+========================
+
+Permits you to add a row to your table. You can submit an array or
+discrete params::
+
+	$this->table->add_row('Blue', 'Red', 'Green');
+
+::
+
+	$this->table->add_row(array('Blue', 'Red', 'Green'));
+
+If you would like to set an individual cell's tag attributes, you can
+use an associative array for that cell. The associative key 'data'
+defines the cell's data. Any other key => val pairs are added as
+key='val' attributes to the tag::
+
+	$cell = array('data' => 'Blue', 'class' => 'highlight', 'colspan' => 2); $this->table->add_row($cell, 'Red', 'Green');  // generates // <td class='highlight' colspan='2'>Blue</td><td>Red</td><td>Green</td>
+
+$this->table->make_columns()
+=============================
+
+This function takes a one-dimensional array as input and creates a
+multi-dimensional array with a depth equal to the number of columns
+desired. This allows a single array with many elements to be displayed
+in a table that has a fixed column count. Consider this example::
+
+	 $list = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve');  $new_list = $this->table->make_columns($list, 3);  $this->table->generate($new_list);  // Generates a table with this prototype  <table border="0" cellpadding="4" cellspacing="0"> <tr> <td>one</td><td>two</td><td>three</td> </tr><tr> <td>four</td><td>five</td><td>six</td> </tr><tr> <td>seven</td><td>eight</td><td>nine</td> </tr><tr> <td>ten</td><td>eleven</td><td>twelve</td></tr> </table>
+
+$this->table->set_template()
+=============================
+
+Permits you to set your template. You can submit a full or partial
+template.
+
+::
+
+	 $tmpl =  array ( 'table_open'  => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">' );   $this->table->set_template($tmpl);
+
+$this->table->set_empty()
+==========================
+
+Let's you set a default value for use in any table cells that are empty.
+You might, for example, set a non-breaking space::
+
+	 $this->table->set_empty("&nbsp;");
+
+$this->table->clear()
+=====================
+
+Lets you clear the table heading and row data. If you need to show
+multiple tables with different data you should to call this function
+after each table has been generated to empty the previous table
+information. Example::
+
+	 $this->load->library('table');  $this->table->set_heading('Name', 'Color', 'Size'); $this->table->add_row('Fred', 'Blue', 'Small'); $this->table->add_row('Mary', 'Red', 'Large'); $this->table->add_row('John', 'Green', 'Medium');  echo $this->table->generate();  $this->table->clear();  $this->table->set_heading('Name', 'Day', 'Delivery'); $this->table->add_row('Fred', 'Wednesday', 'Express'); $this->table->add_row('Mary', 'Monday', 'Air'); $this->table->add_row('John', 'Saturday', 'Overnight');  echo $this->table->generate();
+
+$this->table->function
+======================
+
+Allows you to specify a native PHP function or a valid function array
+object to be applied to all cell data.
+
+::
+
+	$this->load->library('table');  $this->table->set_heading('Name', 'Color', 'Size'); $this->table->add_row('Fred', '<strong>Blue</strong>', 'Small');  $this->table->function = 'htmlspecialchars'; echo $this->table->generate();
+
+In the above example, all cell data would be ran through PHP's
+htmlspecialchars() function, resulting in::
+
+	<td>Fred</td><td>&lt;strong&gt;Blue&lt;/strong&gt;</td><td>Small</td>

+###############
+Trackback Class
+###############
+
+The Trackback Class provides functions that enable you to send and
+receive Trackback data.
+
+If you are not familiar with Trackbacks you'll find more information
+`here <http://en.wikipedia.org/wiki/Trackback>`_.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Trackback class is
+initialized in your controller using the $this->load->library function::
+
+	$this->load->library('trackback');
+
+Once loaded, the Trackback library object will be available using:
+$this->trackback
+
+Sending Trackbacks
+==================
+
+A Trackback can be sent from any of your controller functions using code
+similar to this example::
+
+	$this->load->library('trackback');  $tb_data = array(                 'ping_url'  => 'http://example.com/trackback/456',                 'url'       => 'http://www.my-example.com/blog/entry/123',                 'title'     => 'The Title of My Entry',                 'excerpt'   => 'The entry content.',                 'blog_name' => 'My Blog Name',                 'charset'   => 'utf-8'                 );  if ( ! $this->trackback->send($tb_data)) {      echo $this->trackback->display_errors(); } else {      echo 'Trackback was sent!'; }
+
+Description of array data:
+
+-  **ping_url** - The URL of the site you are sending the Trackback to.
+   You can send Trackbacks to multiple URLs by separating each URL with
+   a comma.
+-  **url** - The URL to YOUR site where the weblog entry can be seen.
+-  **title** - The title of your weblog entry.
+-  **excerpt** - The content of your weblog entry. Note: the Trackback
+   class will automatically send only the first 500 characters of your
+   entry. It will also strip all HTML.
+-  **blog_name** - The name of your weblog.
+-  **charset** - The character encoding your weblog is written in. If
+   omitted, UTF-8 will be used.
+
+The Trackback sending function returns TRUE/FALSE (boolean) on success
+or failure. If it fails, you can retrieve the error message using::
+
+	$this->trackback->display_errors();
+
+Receiving Trackbacks
+====================
+
+Before you can receive Trackbacks you must create a weblog. If you don't
+have a blog yet there's no point in continuing.
+
+Receiving Trackbacks is a little more complex than sending them, only
+because you will need a database table in which to store them, and you
+will need to validate the incoming trackback data. You are encouraged to
+implement a thorough validation process to guard against spam and
+duplicate data. You may also want to limit the number of Trackbacks you
+allow from a particular IP within a given span of time to further
+curtail spam. The process of receiving a Trackback is quite simple; the
+validation is what takes most of the effort.
+
+Your Ping URL
+=============
+
+In order to accept Trackbacks you must display a Trackback URL next to
+each one of your weblog entries. This will be the URL that people will
+use to send you Trackbacks (we will refer to this as your "Ping URL").
+
+Your Ping URL must point to a controller function where your Trackback
+receiving code is located, and the URL must contain the ID number for
+each particular entry, so that when the Trackback is received you'll be
+able to associate it with a particular entry.
+
+For example, if your controller class is called Trackback, and the
+receiving function is called receive, your Ping URLs will look something
+like this::
+
+	http://example.com/index.php/trackback/receive/entry_id
+
+Where entry_id represents the individual ID number for each of your
+entries.
+
+Creating a Trackback Table
+==========================
+
+Before you can receive Trackbacks you must create a table in which to
+store them. Here is a basic prototype for such a table:
+
+CREATE TABLE trackbacks ( tb_id int(10) unsigned NOT NULL
+auto_increment, entry_id int(10) unsigned NOT NULL default 0, url
+varchar(200) NOT NULL, title varchar(100) NOT NULL, excerpt text NOT
+NULL, blog_name varchar(100) NOT NULL, tb_date int(10) NOT NULL,
+ip_address varchar(16) NOT NULL, PRIMARY KEY \`tb_id\` (\`tb_id\`),
+KEY \`entry_id\` (\`entry_id\`) );
+The Trackback specification only requires four pieces of information to
+be sent in a Trackback (url, title, excerpt, blog_name), but to make
+the data more useful we've added a few more fields in the above table
+schema (date, IP address, etc.).
+
+Processing a Trackback
+======================
+
+Here is an example showing how you will receive and process a Trackback.
+The following code is intended for use within the controller function
+where you expect to receive Trackbacks.
+
+::
+
+	$this->load->library('trackback'); $this->load->database();  if ($this->uri->segment(3) == FALSE) {     $this->trackback->send_error("Unable to determine the entry ID"); }  if ( ! $this->trackback->receive()) {     $this->trackback->send_error("The Trackback did not contain valid data"); }  $data = array(                 'tb_id'      => '',                 'entry_id'   => $this->uri->segment(3),                 'url'        => $this->trackback->data('url'),                 'title'      => $this->trackback->data('title'),                 'excerpt'    => $this->trackback->data('excerpt'),                 'blog_name'  => $this->trackback->data('blog_name'),                 'tb_date'    => time(),                 'ip_address' => $this->input->ip_address()                 );  $sql = $this->db->insert_string('trackbacks', $data); $this->db->query($sql);  $this->trackback->send_success();
+
+Notes:
+^^^^^^
+
+The entry ID number is expected in the third segment of your URL. This
+is based on the URI example we gave earlier::
+
+	http://example.com/index.php/trackback/receive/entry_id
+
+Notice the entry_id is in the third URI segment, which you can retrieve
+using::
+
+	$this->uri->segment(3);
+
+In our Trackback receiving code above, if the third segment is missing,
+we will issue an error. Without a valid entry ID, there's no reason to
+continue.
+
+The $this->trackback->receive() function is simply a validation function
+that looks at the incoming data and makes sure it contains the four
+pieces of data that are required (url, title, excerpt, blog_name). It
+returns TRUE on success and FALSE on failure. If it fails you will issue
+an error message.
+
+The incoming Trackback data can be retrieved using this function::
+
+	$this->trackback->data('item')
+
+Where item represents one of these four pieces of info: url, title,
+excerpt, or blog_name
+
+If the Trackback data is successfully received, you will issue a success
+message using::
+
+	$this->trackback->send_success();
+
+.. note:: The above code contains no data validation, which you are
+	encouraged to add.

+Typography Class
+################
+
+The Typography Class provides functions that help you format text.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Typography class is
+initialized in your controller using the $this->load->library function::
+
+	$this->load->library('typography');
+
+Once loaded, the Typography library object will be available using:
+$this->typography
+
+auto_typography()
+==================
+
+Formats text so that it is semantically and typographically correct
+HTML. Takes a string as input and returns it with the following
+formatting:
+
+-  Surrounds paragraphs within <p></p> (looks for double line breaks to
+   identify paragraphs).
+-  Single line breaks are converted to <br />, except those that appear
+   within <pre> tags.
+-  Block level elements, like <div> tags, are not wrapped within
+   paragraphs, but their contained text is if it contains paragraphs.
+-  Quotes are converted to correctly facing curly quote entities, except
+   those that appear within tags.
+-  Apostrophes are converted to curly apostrophe entities.
+-  Double dashes (either like -- this or like--this) are converted to
+   em—dashes.
+-  Three consecutive periods either preceding or following a word are
+   converted to ellipsis…
+-  Double spaces following sentences are converted to non-breaking
+   spaces to mimic double spacing.
+
+Usage example::
+
+	$string = $this->typography->auto_typography($string);
+
+Parameters
+----------
+
+There is one optional parameters that determines whether the parser
+should reduce more then two consecutive line breaks down to two. Use
+boolean TRUE or FALSE.
+
+By default the parser does not reduce line breaks. In other words, if no
+parameters are submitted, it is the same as doing this::
+
+	$string = $this->typography->auto_typography($string, FALSE);
+
+.. note:: Typographic formatting can be processor intensive,
+	particularly if you have a lot of content being formatted. If you choose
+	to use this function you may want to consider :doc:`caching <../general/caching>`
+	your pages.
+
+format_characters()
+====================
+
+This function is similar to the auto_typography function above, except
+that it only does character conversion:
+
+-  Quotes are converted to correctly facing curly quote entities, except
+   those that appear within tags.
+-  Apostrophes are converted to curly apostrophe entities.
+-  Double dashes (either like -- this or like--this) are converted to
+   em—dashes.
+-  Three consecutive periods either preceding or following a word are
+   converted to ellipsis…
+-  Double spaces following sentences are converted to non-breaking
+   spaces to mimic double spacing.
+
+Usage example::
+
+	$string = $this->typography->format_characters($string);
+
+nl2br_except_pre()
+====================
+
+Converts newlines to <br /> tags unless they appear within <pre> tags.
+This function is identical to the native PHP nl2br() function, except
+that it ignores <pre> tags.
+
+Usage example::
+
+	$string = $this->typography->nl2br_except_pre($string);
+
+protect_braced_quotes
+=======================
+
+When using the Typography library in conjunction with the Template
+Parser library it can often be desirable to protect single and double
+quotes within curly braces. To enable this, set the
+protect_braced_quotes class property to TRUE.
+
+Usage example::
+
+	$this->load->library('typography'); $this->typography->protect_braced_quotes = TRUE;

+##################
+Unit Testing Class
+##################
+
+Unit testing is an approach to software development in which tests are
+written for each function in your application. If you are not familiar
+with the concept you might do a little googling on the subject.
+
+CodeIgniter's Unit Test class is quite simple, consisting of an
+evaluation function and two result functions. It's not intended to be a
+full-blown test suite but rather a simple mechanism to evaluate your
+code to determine if it is producing the correct data type and result.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Unit Test class is
+initialized in your controller using the $this->load->library function::
+
+	$this->load->library('unit_test');
+
+Once loaded, the Unit Test object will be available using: $this->unit
+
+Running Tests
+=============
+
+Running a test involves supplying a test and an expected result to the
+following function:
+
+$this->unit->run( test, expected result, 'test name', 'notes');
+===============================================================
+
+Where test is the result of the code you wish to test, expected result
+is the data type you expect, test name is an optional name you can give
+your test, and notes are optional notes. Example::
+
+	$test = 1 + 1;  $expected_result = 2;  $test_name = 'Adds one plus one';  $this->unit->run($test, $expected_result, $test_name);
+
+The expected result you supply can either be a literal match, or a data
+type match. Here's an example of a literal::
+
+	$this->unit->run('Foo', 'Foo');
+
+Here is an example of a data type match::
+
+	$this->unit->run('Foo', 'is_string');
+
+Notice the use of "is_string" in the second parameter? This tells the
+function to evaluate whether your test is producing a string as the
+result. Here is a list of allowed comparison types:
+
+-  is_object
+-  is_string
+-  is_bool
+-  is_true
+-  is_false
+-  is_int
+-  is_numeric
+-  is_float
+-  is_double
+-  is_array
+-  is_null
+
+Generating Reports
+==================
+
+You can either display results after each test, or your can run several
+tests and generate a report at the end. To show a report directly simply
+echo or return the run function::
+
+	echo $this->unit->run($test, $expected_result);
+
+To run a full report of all tests, use this::
+
+	echo $this->unit->report();
+
+The report will be formatted in an HTML table for viewing. If you prefer
+the raw data you can retrieve an array using::
+
+	echo $this->unit->result();
+
+Strict Mode
+===========
+
+By default the unit test class evaluates literal matches loosely.
+Consider this example::
+
+	$this->unit->run(1, TRUE);
+
+The test is evaluating an integer, but the expected result is a boolean.
+PHP, however, due to it's loose data-typing will evaluate the above code
+as TRUE using a normal equality test::
+
+	if (1 == TRUE) echo 'This evaluates as true';
+
+If you prefer, you can put the unit test class in to strict mode, which
+will compare the data type as well as the value::
+
+	if (1 === TRUE) echo 'This evaluates as FALSE';
+
+To enable strict mode use this::
+
+	$this->unit->use_strict(TRUE);
+
+Enabling/Disabling Unit Testing
+===============================
+
+If you would like to leave some testing in place in your scripts, but
+not have it run unless you need it, you can disable unit testing using::
+
+	$this->unit->active(FALSE)
+
+Unit Test Display
+=================
+
+When your unit test results display, the following items show by
+default:
+
+-  Test Name (test_name)
+-  Test Datatype (test_datatype)
+-  Expected Datatype (res_datatype)
+-  Result (result)
+-  File Name (file)
+-  Line Number (line)
+-  Any notes you entered for the test (notes)
+
+You can customize which of these items get displayed by using
+$this->unit->set_items(). For example, if you only wanted the test name
+and the result displayed:
+Customizing displayed tests
+---------------------------
+
+::
+
+	     $this->unit->set_test_items(array('test_name', 'result'));
+
+Creating a Template
+-------------------
+
+If you would like your test results formatted differently then the
+default you can set your own template. Here is an example of a simple
+template. Note the required pseudo-variables::
+
+	 $str = ' <table border="0" cellpadding="4" cellspacing="1">     {rows}         <tr>         <td>{item}</td>         <td>{result}</td>         </tr>     {/rows} </table>';  $this->unit->set_template($str);
+
+.. note:: Your template must be declared **before** running the unit
+	test process.

+#########
+URI Class
+#########
+
+The URI Class provides functions that help you retrieve information from
+your URI strings. If you use URI routing, you can also retrieve
+information about the re-routed segments.
+
+.. note:: This class is initialized automatically by the system so there
+	is no need to do it manually.
+
+$this->uri->segment(n)
+======================
+
+Permits you to retrieve a specific segment. Where n is the segment
+number you wish to retrieve. Segments are numbered from left to right.
+For example, if your full URL is this::
+
+	http://example.com/index.php/news/local/metro/crime_is_up
+
+The segment numbers would be this:
+
+#. news
+#. local
+#. metro
+#. crime_is_up
+
+By default the function returns FALSE (boolean) if the segment does not
+exist. There is an optional second parameter that permits you to set
+your own default value if the segment is missing. For example, this
+would tell the function to return the number zero in the event of
+failure::
+
+	$product_id = $this->uri->segment(3, 0);
+
+It helps avoid having to write code like this::
+
+	if ($this->uri->segment(3) === FALSE) {     $product_id = 0; } else {     $product_id = $this->uri->segment(3); }
+
+$this->uri->rsegment(n)
+=======================
+
+This function is identical to the previous one, except that it lets you
+retrieve a specific segment from your re-routed URI in the event you are
+using CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
+
+$this->uri->slash_segment(n)
+=============================
+
+This function is almost identical to $this->uri->segment(), except it
+adds a trailing and/or leading slash based on the second parameter. If
+the parameter is not used, a trailing slash added. Examples::
+
+	$this->uri->slash_segment(3); $this->uri->slash_segment(3, 'leading'); $this->uri->slash_segment(3, 'both');
+
+Returns:
+
+#. segment/
+#. /segment
+#. /segment/
+
+$this->uri->slash_rsegment(n)
+==============================
+
+This function is identical to the previous one, except that it lets you
+add slashes a specific segment from your re-routed URI in the event you
+are using CodeIgniter's :doc:`URI Routing <../general/routing>`
+feature.
+
+$this->uri->uri_to_assoc(n)
+=============================
+
+This function lets you turn URI segments into and associative array of
+key/value pairs. Consider this URI::
+
+	index.php/user/search/name/joe/location/UK/gender/male
+
+Using this function you can turn the URI into an associative array with
+this prototype::
+
+	[array] (     'name' => 'joe'     'location'  => 'UK'     'gender'    => 'male' )
+
+The first parameter of the function lets you set an offset. By default
+it is set to 3 since your URI will normally contain a
+controller/function in the first and second segments. Example::
+
+	 $array = $this->uri->uri_to_assoc(3);  echo $array['name'];
+
+The second parameter lets you set default key names, so that the array
+returned by the function will always contain expected indexes, even if
+missing from the URI. Example::
+
+	 $default = array('name', 'gender', 'location', 'type', 'sort');  $array = $this->uri->uri_to_assoc(3, $default);
+
+If the URI does not contain a value in your default, an array index will
+be set to that name, with a value of FALSE.
+
+Lastly, if a corresponding value is not found for a given key (if there
+is an odd number of URI segments) the value will be set to FALSE
+(boolean).
+
+$this->uri->ruri_to_assoc(n)
+==============================
+
+This function is identical to the previous one, except that it creates
+an associative array using the re-routed URI in the event you are using
+CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
+
+$this->uri->assoc_to_uri()
+============================
+
+Takes an associative array as input and generates a URI string from it.
+The array keys will be included in the string. Example::
+
+	$array = array('product' => 'shoes', 'size' => 'large', 'color' => 'red');  $str = $this->uri->assoc_to_uri($array);  // Produces:  product/shoes/size/large/color/red
+
+$this->uri->uri_string()
+=========================
+
+Returns a string with the complete URI. For example, if this is your
+full URL::
+
+	http://example.com/index.php/news/local/345
+
+The function would return this::
+
+	/news/local/345
+
+$this->uri->ruri_string()
+==========================
+
+This function is identical to the previous one, except that it returns
+the re-routed URI in the event you are using CodeIgniter's :doc:`URI
+Routing <../general/routing>` feature.
+
+$this->uri->total_segments()
+=============================
+
+Returns the total number of segments.
+
+$this->uri->total_rsegments()
+==============================
+
+This function is identical to the previous one, except that it returns
+the total number of segments in your re-routed URI in the event you are
+using CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
+
+$this->uri->segment_array()
+============================
+
+Returns an array containing the URI segments. For example::
+
+	 $segs = $this->uri->segment_array();  foreach ($segs as $segment) {     echo $segment;     echo '<br />'; }
+
+$this->uri->rsegment_array()
+=============================
+
+This function is identical to the previous one, except that it returns
+the array of segments in your re-routed URI in the event you are using
+CodeIgniter's :doc:`URI Routing <../general/routing>` feature.

+################
+User Agent Class
+################
+
+The User Agent Class provides functions that help identify information
+about the browser, mobile device, or robot visiting your site. In
+addition you can get referrer information as well as language and
+supported character-set information.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the User Agent class is
+initialized in your controller using the $this->load->library function::
+
+	$this->load->library('user_agent');
+
+Once loaded, the object will be available using: $this->agent
+
+User Agent Definitions
+======================
+
+The user agent name definitions are located in a config file located at:
+application/config/user_agents.php. You may add items to the various
+user agent arrays if needed.
+
+Example
+=======
+
+When the User Agent class is initialized it will attempt to determine
+whether the user agent browsing your site is a web browser, a mobile
+device, or a robot. It will also gather the platform information if it
+is available.
+
+::
+
+	 $this->load->library('user_agent');  if ($this->agent->is_browser()) {     $agent  = $this->agent->browser().' '.$this->agent->version(); } elseif ($this->agent->is_robot()) {     $agent = $this->agent->robot(); } elseif ($this->agent->is_mobile()) {     $agent = $this->agent->mobile(); } else {     $agent = 'Unidentified User Agent'; }  echo $agent;  echo $this->agent->platform(); // Platform info (Windows, Linux, Mac, etc.)
+
+******************
+Function Reference
+******************
+
+$this->agent->is_browser()
+===========================
+
+Returns TRUE/FALSE (boolean) if the user agent is a known web browser.
+
+::
+
+	 if ($this->agent->is_browser('Safari')) {     echo 'You are using Safari.'; } else if ($this->agent->is_browser()) {     echo 'You are using a browser.'; }
+
+.. note:: The string "Safari" in this example is an array key in the
+	list of browser definitions. You can find this list in
+	application/config/user_agents.php if you want to add new browsers or
+	change the stings.
+
+$this->agent->is_mobile()
+==========================
+
+Returns TRUE/FALSE (boolean) if the user agent is a known mobile device.
+
+::
+
+	 if ($this->agent->is_mobile('iphone')) {     $this->load->view('iphone/home'); } else if ($this->agent->is_mobile()) {     $this->load->view('mobile/home'); } else {     $this->load->view('web/home'); }
+
+$this->agent->is_robot()
+=========================
+
+Returns TRUE/FALSE (boolean) if the user agent is a known robot.
+
+.. note:: The user agent library only contains the most common robot
+	definitions. It is not a complete list of bots. There are hundreds of
+	them so searching for each one would not be very efficient. If you find
+	that some bots that commonly visit your site are missing from the list
+	you can add them to your application/config/user_agents.php file.
+
+$this->agent->is_referral()
+============================
+
+Returns TRUE/FALSE (boolean) if the user agent was referred from another
+site.
+
+$this->agent->browser()
+=======================
+
+Returns a string containing the name of the web browser viewing your
+site.
+
+$this->agent->version()
+=======================
+
+Returns a string containing the version number of the web browser
+viewing your site.
+
+$this->agent->mobile()
+======================
+
+Returns a string containing the name of the mobile device viewing your
+site.
+
+$this->agent->robot()
+=====================
+
+Returns a string containing the name of the robot viewing your site.
+
+$this->agent->platform()
+========================
+
+Returns a string containing the platform viewing your site (Linux,
+Windows, OS X, etc.).
+
+$this->agent->referrer()
+========================
+
+The referrer, if the user agent was referred from another site.
+Typically you'll test for this as follows::
+
+	 if ($this->agent->is_referral()) {     echo $this->agent->referrer(); }
+
+$this->agent->agent_string()
+=============================
+
+Returns a string containing the full user agent string. Typically it
+will be something like this::
+
+	Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.0.4) Gecko/20060613 Camino/1.0.2
+
+$this->agent->accept_lang()
+============================
+
+Lets you determine if the user agent accepts a particular language.
+Example::
+
+	if ($this->agent->accept_lang('en')) {     echo 'You accept English!'; }
+
+.. note:: This function is not typically very reliable since some
+	browsers do not provide language info, and even among those that do, it
+	is not always accurate.
+
+$this->agent->accept_charset()
+===============================
+
+Lets you determine if the user agent accepts a particular character set.
+Example::
+
+	if ($this->agent->accept_charset('utf-8')) {     echo 'You browser supports UTF-8!'; }
+
+.. note:: This function is not typically very reliable since some
+	browsers do not provide character-set info, and even among those that
+	do, it is not always accurate.

+##################################
+XML-RPC and XML-RPC Server Classes
+##################################
+
+CodeIgniter's XML-RPC classes permit you to send requests to another
+server, or set up your own XML-RPC server to receive requests.
+
+****************
+What is XML-RPC?
+****************
+
+Quite simply it is a way for two computers to communicate over the
+internet using XML. One computer, which we will call the client, sends
+an XML-RPC **request** to another computer, which we will call the
+server. Once the server receives and processes the request it will send
+back a **response** to the client.
+
+For example, using the MetaWeblog API, an XML-RPC Client (usually a
+desktop publishing tool) will send a request to an XML-RPC Server
+running on your site. This request might be a new weblog entry being
+sent for publication, or it could be a request for an existing entry for
+editing. When the XML-RPC Server receives this request it will examine
+it to determine which class/method should be called to process the
+request. Once processed, the server will then send back a response
+message.
+
+For detailed specifications, you can visit the
+`XML-RPC <http://www.xmlrpc.com/>`_ site.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the XML-RPC and XML-RPCS classes
+are initialized in your controller using the $this->load->library
+function:
+
+To load the XML-RPC class you will use::
+
+	$this->load->library('xmlrpc');
+
+Once loaded, the xml-rpc library object will be available using:
+$this->xmlrpc
+
+To load the XML-RPC Server class you will use::
+
+	 $this->load->library('xmlrpc'); $this->load->library('xmlrpcs');
+
+Once loaded, the xml-rpcs library object will be available using:
+$this->xmlrpcs
+
+.. note:: When using the XML-RPC Server class you must load BOTH the
+	XML-RPC class and the XML-RPC Server class.
+
+Sending XML-RPC Requests
+========================
+
+To send a request to an XML-RPC server you must specify the following
+information:
+
+-  The URL of the server
+-  The method on the server you wish to call
+-  The *request* data (explained below).
+
+Here is a basic example that sends a simple Weblogs.com ping to the
+`Ping-o-Matic <http://pingomatic.com/>`_
+
+::
+
+	$this->load->library('xmlrpc');  $this->xmlrpc->server('http://rpc.pingomatic.com/', 80); $this->xmlrpc->method('weblogUpdates.ping');   $request = array('My Photoblog', 'http://www.my-site.com/photoblog/'); $this->xmlrpc->request($request);  if ( ! $this->xmlrpc->send_request()) {     echo $this->xmlrpc->display_error(); }
+
+Explanation
+-----------
+
+The above code initializes the XML-RPC class, sets the server URL and
+method to be called (weblogUpdates.ping). The request (in this case, the
+title and URL of your site) is placed into an array for transportation,
+and compiled using the request() function. Lastly, the full request is
+sent. If the send_request() method returns false we will display the
+error message sent back from the XML-RPC Server.
+
+Anatomy of a Request
+====================
+
+An XML-RPC request is simply the data you are sending to the XML-RPC
+server. Each piece of data in a request is referred to as a request
+parameter. The above example has two parameters: The URL and title of
+your site. When the XML-RPC server receives your request, it will look
+for parameters it requires.
+
+Request parameters must be placed into an array for transportation, and
+each parameter can be one of seven data types (strings, numbers, dates,
+etc.). If your parameters are something other than strings you will have
+to include the data type in the request array.
+
+Here is an example of a simple array with three parameters::
+
+	$request = array('John', 'Doe', 'www.some-site.com'); $this->xmlrpc->request($request);
+
+If you use data types other than strings, or if you have several
+different data types, you will place each parameter into its own array,
+with the data type in the second position::
+
+	 $request = array (                    array('John', 'string'),                    array('Doe', 'string'),                    array(FALSE, 'boolean'),                    array(12345, 'int')                  );  $this->xmlrpc->request($request);
+
+The `Data Types <#datatypes>`_ section below has a full list of data
+types.
+Creating an XML-RPC Server
+==========================
+
+An XML-RPC Server acts as a traffic cop of sorts, waiting for incoming
+requests and redirecting them to the appropriate functions for
+processing.
+
+To create your own XML-RPC server involves initializing the XML-RPC
+Server class in your controller where you expect the incoming request to
+appear, then setting up an array with mapping instructions so that
+incoming requests can be sent to the appropriate class and method for
+processing.
+
+Here is an example to illustrate::
+
+	 $this->load->library('xmlrpc'); $this->load->library('xmlrpcs');  $config['functions']['new_post'] = array('function' => 'My_blog.new_entry'), $config['functions']['update_post'] = array('function' => 'My_blog.update_entry'); $config['object'] = $this;  $this->xmlrpcs->initialize($config); $this->xmlrpcs->serve();
+
+The above example contains an array specifying two method requests that
+the Server allows. The allowed methods are on the left side of the
+array. When either of those are received, they will be mapped to the
+class and method on the right.
+
+The 'object' key is a special key that you pass an instantiated class
+object with, which is necessary when the method you are mapping to is
+not part of the CodeIgniter super object.
+
+In other words, if an XML-RPC Client sends a request for the new_post
+method, your server will load the My_blog class and call the new_entry
+function. If the request is for the update_post method, your server
+will load the My_blog class and call the update_entry function.
+
+The function names in the above example are arbitrary. You'll decide
+what they should be called on your server, or if you are using
+standardized APIs, like the Blogger or MetaWeblog API, you'll use their
+function names.
+
+There are two additional configuration keys you may make use of when
+initializing the server class: debug can be set to TRUE in order to
+enable debugging, and xss_clean may be set to FALSE to prevent sending
+data through the Security library's xss_clean function.
+
+Processing Server Requests
+==========================
+
+When the XML-RPC Server receives a request and loads the class/method
+for processing, it will pass an object to that method containing the
+data sent by the client.
+
+Using the above example, if the new_post method is requested, the
+server will expect a class to exist with this prototype::
+
+	class My_blog extends CI_Controller {      function new_post($request)     {          } }
+
+The $request variable is an object compiled by the Server, which
+contains the data sent by the XML-RPC Client. Using this object you will
+have access to the *request parameters* enabling you to process the
+request. When you are done you will send a Response back to the Client.
+
+Below is a real-world example, using the Blogger API. One of the methods
+in the Blogger API is getUserInfo(). Using this method, an XML-RPC
+Client can send the Server a username and password, in return the Server
+sends back information about that particular user (nickname, user ID,
+email address, etc.). Here is how the processing function might look::
+
+	class My_blog extends CI_Controller {      function getUserInfo($request)     {          $username = 'smitty';         $password = 'secretsmittypass';          $this->load->library('xmlrpc');              $parameters = $request->output_parameters();              if ($parameters['1'] != $username AND $parameters['2'] != $password)         {             return $this->xmlrpc->send_error_message('100', 'Invalid Access');         }              $response = array(array('nickname'  => array('Smitty','string'),                                 'userid'    => array('99','string'),                                 'url'       => array('http://yoursite.com','string'),                                 'email'     => array('jsmith@yoursite.com','string'),                                 'lastname'  => array('Smith','string'),                                 'firstname' => array('John','string')                                 ),                          'struct');          return $this->xmlrpc->send_response($response);     } }
+
+Notes:
+------
+
+The output_parameters() function retrieves an indexed array
+corresponding to the request parameters sent by the client. In the above
+example, the output parameters will be the username and password.
+
+If the username and password sent by the client were not valid, and
+error message is returned using send_error_message().
+
+If the operation was successful, the client will be sent back a response
+array containing the user's info.
+
+Formatting a Response
+=====================
+
+Similar to *Requests*, *Responses* must be formatted as an array.
+However, unlike requests, a response is an array **that contains a
+single item**. This item can be an array with several additional arrays,
+but there can be only one primary array index. In other words, the basic
+prototype is this::
+
+	$response = array('Response data',  'array');
+
+Responses, however, usually contain multiple pieces of information. In
+order to accomplish this we must put the response into its own array so
+that the primary array continues to contain a single piece of data.
+Here's an example showing how this might be accomplished::
+
+	 $response = array (                    array(                          'first_name' => array('John', 'string'),                          'last_name' => array('Doe', 'string'),                          'member_id' => array(123435, 'int'),                          'todo_list' => array(array('clean house', 'call mom', 'water plants'), 'array'),                         ),                  'struct'                  );
+
+Notice that the above array is formatted as a struct. This is the most
+common data type for responses.
+
+As with Requests, a response can be one of the seven data types listed
+in the `Data Types <#datatypes>`_ section.
+
+Sending an Error Response
+=========================
+
+If you need to send the client an error response you will use the
+following::
+
+	return $this->xmlrpc->send_error_message('123', 'Requested data not available');
+
+The first parameter is the error number while the second parameter is
+the error message.
+
+Creating Your Own Client and Server
+===================================
+
+To help you understand everything we've covered thus far, let's create a
+couple controllers that act as XML-RPC Client and Server. You'll use the
+Client to send a request to the Server and receive a response.
+
+The Client
+----------
+
+Using a text editor, create a controller called xmlrpc_client.php. In
+it, place this code and save it to your applications/controllers/
+folder:
+
+<?php class Xmlrpc_client extends CI_Controller { function index() {
+$this->load->helper('url'); $server_url = site_url('xmlrpc_server');
+$this->load->library('xmlrpc'); $this->xmlrpc->server($server_url, 80);
+$this->xmlrpc->method('Greetings'); $request = array('How is it
+going?'); $this->xmlrpc->request($request); if ( !
+$this->xmlrpc->send_request()) { echo $this->xmlrpc->display_error();
+} else { echo '
+::
+
+    ';
+                print_r($this->xmlrpc->display_response());
+                echo '
+
+'; } } } ?>
+Note: In the above code we are using a "url helper". You can find more
+information in the :doc:`Helpers Functions <../general/helpers>` page.
+
+The Server
+----------
+
+Using a text editor, create a controller called xmlrpc_server.php. In
+it, place this code and save it to your applications/controllers/
+folder:
+
+<?php class Xmlrpc_server extends CI_Controller { function index() {
+$this->load->library('xmlrpc'); $this->load->library('xmlrpcs');
+$config['functions']['Greetings'] = array('function' =>
+'Xmlrpc_server.process'); $this->xmlrpcs->initialize($config);
+$this->xmlrpcs->serve(); } function process($request) { $parameters =
+$request->output_parameters(); $response = array( array( 'you_said' =>
+$parameters['0'], 'i_respond' => 'Not bad at all.'), 'struct'); return
+$this->xmlrpc->send_response($response); } } ?>
+Try it!
+-------
+
+Now visit the your site using a URL similar to this::
+
+	example.com/index.php/xmlrpc_client/
+
+You should now see the message you sent to the server, and its response
+back to you.
+
+The client you created sends a message ("How's is going?") to the
+server, along with a request for the "Greetings" method. The Server
+receives the request and maps it to the "process" function, where a
+response is sent back.
+
+Using Associative Arrays In a Request Parameter
+===============================================
+
+If you wish to use an associative array in your method parameters you
+will need to use a struct datatype::
+
+	$request = array(                      array(                            // Param 0                            array(                                  'name'=>'John'                                     ),                                  'struct'                            ),                            array(                                  // Param 1                                  array(                                           'size'=>'large',                                        'shape'=>'round'                                           ),                                  'struct'                            )                      );     $this->xmlrpc->request($request);
+
+You can retrieve the associative array when processing the request in
+the Server.
+
+::
+
+	$parameters = $request->output_parameters();     $name = $parameters['0']['name'];     $size = $parameters['1']['size'];     $size = $parameters['1']['shape']; 
+
+**************************
+XML-RPC Function Reference
+**************************
+
+$this->xmlrpc->server()
+=======================
+
+Sets the URL and port number of the server to which a request is to be

+##################
+Zip Encoding Class
+##################
+
+CodeIgniter's Zip Encoding Class classes permit you to create Zip
+archives. Archives can be downloaded to your desktop or saved to a
+directory.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Zip class is initialized in
+your controller using the $this->load->library function::
+
+	$this->load->library('zip');
+
+Once loaded, the Zip library object will be available using: $this->zip
+
+Usage Example
+=============
+
+This example demonstrates how to compress a file, save it to a folder on
+your server, and download it to your desktop.
+
+::
+
+	 $name = 'mydata1.txt'; $data = 'A Data String!';  $this->zip->add_data($name, $data);  // Write the zip file to a folder on your server. Name it "my_backup.zip" $this->zip->archive('/path/to/directory/my_backup.zip');   // Download the file to your desktop.  Name it "my_backup.zip" $this->zip->download('my_backup.zip');
+
+******************
+Function Reference
+******************
+
+$this->zip->add_data()
+=======================
+
+Permits you to add data to the Zip archive. The first parameter must
+contain the name you would like given to the file, the second parameter
+must contain the file data as a string::
+
+	 $name = 'my_bio.txt'; $data = 'I was born in an elevator...';  $this->zip->add_data($name, $data);
+
+You are allowed multiple calls to this function in order to add several
+files to your archive. Example::
+
+	 $name = 'mydata1.txt'; $data = 'A Data String!'; $this->zip->add_data($name, $data);  $name = 'mydata2.txt'; $data = 'Another Data String!'; $this->zip->add_data($name, $data);
+
+Or you can pass multiple files using an array::
+
+	 $data = array(                 'mydata1.txt' => 'A Data String!',                 'mydata2.txt' => 'Another Data String!'             );  $this->zip->add_data($data);  $this->zip->download('my_backup.zip');
+
+If you would like your compressed data organized into sub-folders,
+include the path as part of the filename::
+
+	 $name = 'personal/my_bio.txt'; $data = 'I was born in an elevator...';  $this->zip->add_data($name, $data);
+
+The above example will place my_bio.txt inside a folder called
+personal.
+
+$this->zip->add_dir()
+======================
+
+Permits you to add a directory. Usually this function is unnecessary
+since you can place your data into folders when using
+$this->zip->add_data(), but if you would like to create an empty folder
+you can do so. Example::
+
+	$this->zip->add_dir('myfolder'); // Creates a folder called "myfolder"
+
+$this->zip->read_file()
+========================
+
+Permits you to compress a file that already exists somewhere on your
+server. Supply a file path and the zip class will read it and add it to
+the archive::
+
+	 $path = '/path/to/photo.jpg'; $this->zip->read_file($path);   // Download the file to your desktop.  Name it "my_backup.zip" $this->zip->download('my_backup.zip');
+
+If you would like the Zip archive to maintain the directory structure of
+the file in it, pass TRUE (boolean) in the second parameter. Example::
+
+	 $path = '/path/to/photo.jpg'; $this->zip->read_file($path, TRUE);   // Download the file to your desktop.  Name it "my_backup.zip" $this->zip->download('my_backup.zip');
+
+In the above example, photo.jpg will be placed inside two folders:
+path/to/
+
+$this->zip->read_dir()
+=======================
+
+Permits you to compress a folder (and its contents) that already exists
+somewhere on your server. Supply a file path to the directory and the
+zip class will recursively read it and recreate it as a Zip archive. All
+files contained within the supplied path will be encoded, as will any
+sub-folders contained within it. Example::
+
+	 $path = '/path/to/your/directory/'; $this->zip->read_dir($path);   // Download the file to your desktop.  Name it "my_backup.zip" $this->zip->download('my_backup.zip');
+
+By default the Zip archive will place all directories listed in the
+first parameter inside the zip. If you want the tree preceding the
+target folder to be ignored you can pass FALSE (boolean) in the second
+parameter. Example::
+
+	 $path = '/path/to/your/directory/'; $this->zip->read_dir($path, FALSE);
+
+This will create a ZIP with the folder "directory" inside, then all
+sub-folders stored correctly inside that, but will not include the
+folders /path/to/your.
+
+$this->zip->archive()
+=====================
+
+Writes the Zip-encoded file to a directory on your server. Submit a
+valid server path ending in the file name. Make sure the directory is
+writable (666 or 777 is usually OK). Example::
+
+	$this->zip->archive('/path/to/folder/myarchive.zip'); // Creates a file named myarchive.zip
+
+$this->zip->download()
+======================
+
+Causes the Zip file to be downloaded from your server. The function must
+be passed the name you would like the zip file called. Example::
+
+	$this->zip->download('latest_stuff.zip'); // File will be named "latest_stuff.zip"
+
+.. note:: Do not display any data in the controller in which you call
+	this function since it sends various server headers that cause the
+	download to happen and the file to be treated as binary.
+
+$this->zip->get_zip()
+======================
+
+Returns the Zip-compressed file data. Generally you will not need this
+function unless you want to do something unique with the data. Example::
+
+	 $name = 'my_bio.txt'; $data = 'I was born in an elevator...';  $this->zip->add_data($name, $data);  $zip_file = $this->zip->get_zip();
+
+$this->zip->clear_data()
+=========================
+
+The Zip class caches your zip data so that it doesn't need to recompile
+the Zip archive for each function you use above. If, however, you need
+to create multiple Zips, each with different data, you can clear the
+cache between calls. Example::
+
+	 $name = 'my_bio.txt'; $data = 'I was born in an elevator...';  $this->zip->add_data($name, $data); $zip_file = $this->zip->get_zip();  $this->zip->clear_data();   $name = 'photo.jpg'; $this->zip->read_file("/path/to/photo.jpg"); // Read the file's contents  $this->zip->download('myphotos.zip');

+Application Flow Chart
+######################
+
+The following graphic illustrates how data flows throughout the system:
+
+|CodeIgniter application flow|
+
+#. The index.php serves as the front controller, initializing the base
+   resources needed to run CodeIgniter.
+#. The Router examines the HTTP request to determine what should be done
+   with it.
+#. If a cache file exists, it is sent directly to the browser, bypassing
+   the normal system execution.
+#. Security. Before the application controller is loaded, the HTTP
+   request and any user submitted data is filtered for security.
+#. The Controller loads the model, core libraries, helpers, and any
+   other resources needed to process the specific request.
+#. The finalized View is rendered then sent to the web browser to be
+   seen. If caching is enabled, the view is cached first so that on
+   subsequent requests it can be served.

+#######################
+CodeIgniter at a Glance
+#######################
+
+CodeIgniter is an Application Framework
+=======================================
+
+CodeIgniter is a toolkit for people who build web applications using
+PHP. Its goal is to enable you to develop projects much faster than you
+could if you were writing code from scratch, by providing a rich set of
+libraries for commonly needed tasks, as well as a simple interface and
+logical structure to access these libraries. CodeIgniter lets you
+creatively focus on your project by minimizing the amount of code needed
+for a given task.
+
+CodeIgniter is Free
+===================
+
+CodeIgniter is licensed under an Apache/BSD-style open source license so
+you can use it however you please. For more information please read the
+:doc:`license agreement <../license>`.
+
+CodeIgniter is Light Weight
+===========================
+
+Truly light weight. The core system requires only a few very small
+libraries. This is in stark contrast to many frameworks that require
+significantly more resources. Additional libraries are loaded
+dynamically upon request, based on your needs for a given process, so
+the base system is very lean and quite fast.
+
+CodeIgniter is Fast
+===================
+
+Really fast. We challenge you to find a framework that has better
+performance than CodeIgniter.
+
+CodeIgniter Uses M-V-C
+======================
+
+CodeIgniter uses the Model-View-Controller approach, which allows great
+separation between logic and presentation. This is particularly good for
+projects in which designers are working with your template files, as the
+code these file contain will be minimized. We describe MVC in more
+detail on its own page.
+
+CodeIgniter Generates Clean URLs
+================================
+
+The URLs generated by CodeIgniter are clean and search-engine friendly.
+Rather than using the standard "query string" approach to URLs that is
+synonymous with dynamic systems, CodeIgniter uses a segment-based
+approach::
+
+	example.com/news/article/345
+
+Note: By default the index.php file is included in the URL but it can be
+removed using a simple .htaccess file.
+
+CodeIgniter Packs a Punch
+=========================
+
+CodeIgniter comes with full-range of libraries that enable the most
+commonly needed web development tasks, like accessing a database,
+sending email, validating form data, maintaining sessions, manipulating
+images, working with XML-RPC data and much more.
+
+CodeIgniter is Extensible
+=========================
+
+The system can be easily extended through the use of your own libraries,
+helpers, or through class extensions or system hooks.
+
+CodeIgniter Does Not Require a Template Engine
+==============================================
+
+Although CodeIgniter *does* come with a simple template parser that can
+be optionally used, it does not force you to use one. Template engines
+simply can not match the performance of native PHP, and the syntax that
+must be learned to use a template engine is usually only marginally
+easier than learning the basics of PHP. Consider this block of PHP code::
+
+	<ul>  <?php foreach ($addressbook as $name):?>  <li><?=$name?></li>  <?php endforeach; ?>  </ul>
+
+Contrast this with the pseudo-code used by a template engine::
+
+	<ul>  {foreach from=$addressbook item="name"}  <li>{$name}</li>  {/foreach}  </ul>
+
+Yes, the template engine example is a bit cleaner, but it comes at the
+price of performance, as the pseudo-code must be converted back into PHP
+to run. Since one of our goals is *maximum performance*, we opted to not
+require the use of a template engine.
+
+CodeIgniter is Thoroughly Documented
+====================================
+
+Programmers love to code and hate to write documentation. We're no
+different, of course, but since documentation is **as important** as the
+code itself, we are committed to doing it. Our source code is extremely
+clean and well commented as well.
+
+CodeIgniter has a Friendly Community of Users
+=============================================
+
+Our growing community of users can be seen actively participating in our
+`Community Forums <http://codeigniter.com/forums/>`_.

+CodeIgniter Features
+####################
+
+Features in and of themselves are a very poor way to judge an
+application since they tell you nothing about the user experience, or
+how intuitively or intelligently it is designed. Features don't reveal
+anything about the quality of the code, or the performance, or the

+Getting Started With CodeIgniter
+################################
+
+Any software application requires some effort to learn. We've done our
+best to minimize the learning curve while making the process as
+enjoyable as possible.
+
+The first step is to :doc:`install <../installation/index>`
+CodeIgniter, then read all the topics in the **Introduction** section of
+the Table of Contents.
+
+Next, read each of the **General Topics** pages in order. Each topic
+builds on the previous one, and includes code examples that you are
+encouraged to try.
+
+Once you understand the basics you'll be ready to explore the **Class
+Reference** and **Helper Reference** pages to learn to utilize the
+native libraries and helper files.
+
+Feel free to take advantage of our `Community
+Forums <http://codeigniter.com/forums/>`_ if you have questions or
+problems, and our `Wiki <http://codeigniter.com/wiki/>`_ to see code
+examples posted by other users.

+##############################
+Design and Architectural Goals
+##############################
+
+Our goal for CodeIgniter is maximum performance, capability, and
+flexibility in the smallest, lightest possible package.
+
+To meet this goal we are committed to benchmarking, re-factoring, and
+simplifying at every step of the development process, rejecting anything
+that doesn't further the stated objective.
+
+From a technical and architectural standpoint, CodeIgniter was created
+with the following objectives:
+
+-  **Dynamic Instantiation.** In CodeIgniter, components are loaded and
+   routines executed only when requested, rather than globally. No
+   assumptions are made by the system regarding what may be needed
+   beyond the minimal core resources, so the system is very light-weight
+   by default. The events, as triggered by the HTTP request, and the
+   controllers and views you design will determine what is invoked.
+-  **Loose Coupling.** Coupling is the degree to which components of a
+   system rely on each other. The less components depend on each other
+   the more reusable and flexible the system becomes. Our goal was a
+   very loosely coupled system.
+-  **Component Singularity.** Singularity is the degree to which
+   components have a narrowly focused purpose. In CodeIgniter, each
+   class and its functions are highly autonomous in order to allow
+   maximum usefulness.
+
+CodeIgniter is a dynamically instantiated, loosely coupled system with
+high component singularity. It strives for simplicity, flexibility, and
+high performance in a small footprint package.

+#####################
+Model-View-Controller
+#####################
+
+CodeIgniter is based on the Model-View-Controller development pattern.
+MVC is a software approach that separates application logic from
+presentation. In practice, it permits your web pages to contain minimal
+scripting since the presentation is separate from the PHP scripting.
+
+-  The **Model** represents your data structures. Typically your model
+   classes will contain functions that help you retrieve, insert, and
+   update information in your database.
+-  The **View** is the information that is being presented to a user. A
+   View will normally be a web page, but in CodeIgniter, a view can also
+   be a page fragment like a header or footer. It can also be an RSS
+   page, or any other type of "page".
+-  The **Controller** serves as an *intermediary* between the Model, the
+   View, and any other resources needed to process the HTTP request and
+   generate a web page.
+
+CodeIgniter has a fairly loose approach to MVC since Models are not
+required. If you don't need the added separation, or find that
+maintaining models requires more complexity than you want, you can
+ignore them and build your application minimally using Controllers and
+Views. CodeIgniter also enables you to incorporate your own existing
+scripts, or even develop core libraries for the system, enabling you to
+work in a way that makes the most sense to you.

+
+	<h5>Email Address</h5>
+	<?php echo form_error('email'); ?>
+	<input type="text" name="email" value="<?php echo set_value('email'); ?>" size="50" />
+
 If there are no errors, nothing will be shown. If there is an error, the
 message will appear.
 
 **Important Note:** If you use an array as the name of a form field, you
 must supply it as an array to the function. Example::
 
-	<?php echo form_error('options[size]'); ?> <input type="text" name="options[size]" value="<?php echo set_value("options[size]"); ?>" size="50" />
+	<?php echo form_error('options[size]'); ?>
+	<input type="text" name="options[size]" value="<?php echo set_value("options[size]"); ?>" size="50" />

-image headers.
-R, C, X, W
-**quality**
-90%
-1 - 100%
-Sets the quality of the image. The higher the quality the larger the
-file size.
-R, C, X, W
-**new_image**
-None
-None
-Sets the destination image name/path. You'll use this preference when
-creating an image copy. The path must be a relative or absolute server
-path, not a URL.

-**height**
-None
-None
-Sets the height you would like the image set to.
-R, C
-**create_thumb**
-FALSE
-TRUE/FALSE (boolean)
-Tells the image processing function to create a thumb.
-R
-**thumb_marker**
-_thumb
-None
-Specifies the thumbnail indicator. It will be inserted just before the
-file extension, so mypic.jpg would become mypic_thumb.jpg
-R
-**maintain_ratio**
-TRUE
-TRUE/FALSE (boolean)
-Specifies whether to maintain the original aspect ratio when resizing or
-use hard values.
-R, C
-**master_dim**
-auto
-auto, width, height
-Specifies what to use as the master axis when resizing or creating
-thumbs. For example, let's say you want to resize an image to 100 X 75
-pixels. If the source image size does not allow perfect resizing to
-those dimensions, this setting determines which axis should be used as
-the hard value. "auto" sets the axis automatically based on whether the
-image is taller then wider, or vice versa.
-R
-**rotation_angle**
-None
-90, 180, 270, vrt, hor
-Specifies the angle of rotation when rotating images. Note that PHP
-rotates counter-clockwise, so a 90 degree rotation to the right must be
-specified as 270.
-X
-**x_axis**
-None
-None
-Sets the X coordinate in pixels for image cropping. For example, a
-setting of 30 will crop an image 30 pixels from the left.
-C
-**y_axis**
-None
-None
-Sets the Y coordinate in pixels for image cropping. For example, a
-setting of 30 will crop an image 30 pixels from the top.

-<h2>Version 2.0.3</h2>
-<p>Release Date: August 20, 2011</p>
-
-<ul>
-	<li>Security
-		<ul>
-			<li>An improvement was made to the MySQL and MySQLi drivers to prevent exposing a potential vector for SQL injection on sites using multi-byte character sets in the database client connection.  <p>An incompatibility in PHP versions &lt; 5.2.3 and MySQL &lt; 5.0.7 with <em>mysql_set_charset()</em> creates a situation where using multi-byte  character sets on these environments may potentially expose a SQL injection attack vector.  Latin-1, UTF-8, and other "low ASCII" character sets are unaffected on all environments.</p>  <p class="critical">If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable.</p></li>

-<h1>Active Record Class</h1>
-
-<p>CodeIgniter uses a modified version of the Active Record Database Pattern.
-This pattern allows information to be retrieved, inserted, and updated in your database with minimal scripting.
-In some cases only one or two lines of code are necessary to perform a database action.
-CodeIgniter does not require that each database table be its own class file.  It instead provides a more simplified interface.</p>
-
-<p>Beyond simplicity, a major benefit to using the Active Record features is that it allows you to create database independent applications, since the query syntax
-is generated by each database adapter.  It also allows for safer queries, since the values are escaped automatically by the system.</p>
-
-<p class="important"><strong>Note:</strong>  If you intend to write your own queries you can disable this class in your database config file, allowing the core database library and adapter to utilize fewer resources.<br /></p>
-
-<ul>
-<li><a href="#select">Selecting Data</a></li>
-<li><a href="#insert">Inserting Data</a></li>
-<li><a href="#update">Updating Data</a></li>
-<li><a href="#delete">Deleting Data</a></li>
-<li><a href="#chaining">Method Chaining</a></li>
-<li><a href="#caching">Active Record Caching</a></li>
-</ul>
-
-<h1><a name="select">&nbsp;</a>Selecting Data</h1>
-
-<p>The following functions allow you to build SQL <strong>SELECT</strong> statements.</p>
-
-<p><strong>Note: If you are using PHP 5 you can use method chaining for more compact syntax. This is described at the end of the page.</strong></p>
-
-
-<h2>$this->db->get();</h2>
-
-<p>Runs the selection query and returns the result.  Can be used by itself to retrieve all records from a table:</p>
-
-<code>$query = $this->db->get('mytable');<br />
-<br />
-// Produces: SELECT * FROM mytable</code>
-
-<p>The second and third parameters enable you to set a limit and offset clause:</p>
-
-<code>$query = $this->db->get('mytable', 10, 20);<br />
-<br />
-// Produces: SELECT * FROM mytable LIMIT 20, 10 (in MySQL. Other databases have slightly different syntax)</code>
-
-<p>You'll notice that the above function is assigned to a variable named <kbd>$query</kbd>, which can be used to show the results:</p>
-
-<code>$query = $this->db->get('mytable');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-}</code>
-
-<p>Please visit the <a href="results.html">result functions</a> page for a full discussion regarding result generation.</p>
-
-
-<h2>$this->db->get_where();</h2>
-
-<p>Identical to the above function except that it permits you to add a "where" clause in the second parameter,
-instead of using the db->where() function:</p>
-
-<code>$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);</code>
-
-<p>Please read the about the where function below for more information.</p>
-<p class="important">Note: get_where() was formerly known as getwhere(), which has been removed</p>
-
-<h2>$this->db->select();</h2>
-<p>Permits you to write the SELECT portion of your query:</p>
-<p><code>
-$this->db->select('title, content, date');<br />
-<br />
-$query = $this->db->get('mytable');<br />
-<br />
-// Produces: SELECT title, content, date FROM mytable</code></p>
-<p class="important"><strong>Note:</strong> If you are selecting all (*) from a table you do not need to use this function.  When omitted, CodeIgniter assumes you wish to SELECT *</p>
-
-<p>$this-&gt;db-&gt;select() accepts an optional second parameter. If you set it to FALSE, CodeIgniter will not try to protect your field or table names with backticks. This is useful if you need a compound select statement.</p>
-<p><code>$this-&gt;db-&gt;select('(SELECT SUM(payments.amount) FROM payments WHERE payments.invoice_id=4') AS amount_paid', FALSE); <br />
-$query = $this-&gt;db-&gt;get('mytable');<br />
-</code></p>
-<h2>$this->db->select_max();</h2>
-<p>Writes a "SELECT MAX(field)" portion for your query. You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_max('age');<br />
-$query = $this->db->get('members');<br />
-
-// Produces: SELECT MAX(age) as age FROM members<br />
-<br />
-$this-&gt;db-&gt;select_max('age', 'member_age');<br />
-$query = $this-&gt;db-&gt;get('members');<br />
-// Produces: SELECT MAX(age) as member_age FROM members</code></p>
-
-<h2>$this->db->select_min();</h2>
-<p>Writes a "SELECT MIN(field)" portion for your query. As with <dfn>select_max()</dfn>, You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_min('age');<br />
-$query = $this->db->get('members');<br />
-// Produces: SELECT MIN(age) as age FROM members</code></p>
-
-<h2>$this->db->select_avg();</h2>
-<p>Writes a "SELECT AVG(field)" portion for your query. As with <dfn>select_max()</dfn>, You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_avg('age');<br />
-$query = $this->db->get('members');<br />
-// Produces: SELECT AVG(age) as age FROM members</code></p>
-
-<h2>$this->db->select_sum();</h2>
-<p>Writes a "SELECT SUM(field)" portion for your query. As with <dfn>select_max()</dfn>, You can optionally include a second parameter to rename the resulting field.</p>
-<p><code>
-$this->db->select_sum('age');<br />
-$query = $this->db->get('members');<br />
-// Produces: SELECT SUM(age) as age FROM members</code></p>
-
-<h2>$this->db->from();</h2>
-
-<p>Permits you to write the FROM portion of your query:</p>
-
-<code>
-$this->db->select('title, content, date');<br />
-$this->db->from('mytable');<br />
-<br />
-$query = $this->db->get();<br />
-<br />
-// Produces: SELECT title, content, date FROM mytable</code>
-
-<p class="important">Note: As shown earlier, the FROM portion of your query can be specified in the <dfn>$this->db->get()</dfn> function, so use whichever method
-you prefer.</p>
-
-<h2>$this->db->join();</h2>
-
-<p>Permits you to write the JOIN portion of your query:</p>
-
-<code>
-$this->db->select('*');<br />
-$this->db->from('blogs');<br />
-$this->db->join('comments', 'comments.id = blogs.id');<br />
-<br />
-$query = $this->db->get();<br />
-<br />
-// Produces: <br />
-// SELECT * FROM blogs<br />
-// JOIN comments ON comments.id = blogs.id<br />
-</code>
-
-<p>Multiple function calls can be made if you need several joins in one query.</p>
-
-<p>If you need a specific type of JOIN you can specify it via the third parameter of the function.
-Options are: left, right, outer, inner, left outer, and right outer.</p>
-
-<code>
-$this->db->join('comments', 'comments.id = blogs.id', <strong>'left'</strong>);<br />
-<br />
-// Produces: LEFT JOIN comments ON comments.id = blogs.id</code>
-
-
-
-
-
-<h2>$this->db->where();</h2>
-<p>This function enables you to set <strong>WHERE</strong> clauses using one of four methods:</p>
-
-<p class="important"><strong>Note:</strong> All values passed to this function are escaped automatically, producing safer queries.</p>
-
-<ol>
-	<li><strong>Simple key/value method:</strong>
-
-	<code>$this->db->where('name', $name);
-	<br /><br />// Produces: WHERE name = 'Joe'	</code>
-
-	<p>Notice that the equal sign is added for you.</p>
-
-	<p>If you use multiple function calls they will be chained together with <var>AND</var> between them:</p>
-
-	<code>$this->db->where('name', $name);<br />
-	$this->db->where('title', $title);<br />
-	$this->db->where('status', $status);
-	<br /><br />// WHERE name = 'Joe' AND title = 'boss' AND status = 'active'	</code>	</li>
-
-	<li><strong>Custom key/value method:</strong>
-
-	<p>You can include an operator in the first parameter in order to control the comparison:</p>
-
-	<code>$this->db->where('name !=', $name);<br />
-	$this->db->where('id <', $id);
-	<br /><br />// Produces: WHERE name != 'Joe' AND id < 45	</code>	</li>
-	<li><strong>Associative array method:</strong>
-
-
-	<code>
-	$array = array('name' => $name, 'title' => $title, 'status' => $status);<br /><br />
-
-	$this->db->where($array);
-	<br /><br />// Produces: WHERE name = 'Joe' AND title = 'boss' AND status = 'active'	</code>
-
-	<p>You can include your own operators using this method as well:</p>
-
-	<code>
-	$array = array('name !=' => $name, 'id <' => $id, 'date >' => $date);<br /><br />
-
-	$this->db->where($array);</code>	</li>
-		<li><strong>Custom string:</strong>
-
-		<p>You can write your own clauses manually:</p>
-
-		<code>
-		$where = "name='Joe' AND status='boss' OR status='active'";<br /><br />
-		$this->db->where($where);</code></li>
-	</ol>
-
-
-<p>$this-&gt;db-&gt;where() accepts an optional third parameter. If you set it to FALSE, CodeIgniter will not try to protect your field or table names with backticks.</p>
-<p><code>		$this-&gt;db-&gt;where('MATCH (field) AGAINST (&quot;value&quot;)', NULL, FALSE);<br />
-</code></p>
-<h2>$this->db->or_where();</h2>
-<p>This function is identical to the one above, except that multiple instances are joined by OR:</p>
-
-<code>
-$this->db->where('name !=', $name);<br />
-$this->db->or_where('id >', $id);
-<br />
-<br />// Produces: WHERE name != 'Joe' OR id > 50</code>
-
-<p class="important">Note: or_where() was formerly known as orwhere(), which has been removed.</p>
-
-
-<h2>$this->db->where_in();</h2>
-<p>Generates a WHERE field IN ('item', 'item') SQL query joined with  AND if appropriate</p>
-<p><code>
-	$names = array('Frank', 'Todd', 'James');<br />
-	$this->db->where_in('username', $names);<br />
-	// Produces: WHERE username IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->or_where_in();</h2>
-<p>Generates a WHERE field IN ('item', 'item') SQL query joined with OR if appropriate</p>
-<p><code>
-	$names = array('Frank', 'Todd', 'James');<br />
-	$this->db->or_where_in('username', $names);<br />
-	// Produces: OR username IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->where_not_in();</h2>
-<p>Generates a WHERE field NOT IN ('item', 'item') SQL query joined with AND if appropriate</p>
-<p><code>
-	$names = array('Frank', 'Todd', 'James');<br />
-	$this->db->where_not_in('username', $names);<br />
-	// Produces: WHERE username NOT IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->or_where_not_in();</h2>
-<p>Generates a WHERE field NOT IN ('item', 'item') SQL query joined with OR if appropriate</p>
-<p><code>
-	$names = array('Frank', 'Todd', 'James');<br />
-	$this->db->or_where_not_in('username', $names);<br />
-	// Produces: OR username NOT IN ('Frank', 'Todd', 'James')</code></p>
-
-<h2>$this->db->like();</h2>
-<p>This function enables you to generate <strong>LIKE</strong> clauses, useful for doing searches.</p>
-
-<p class="important"><strong>Note:</strong> All values passed to this function are escaped automatically.</p>
-
-
-<ol>
-	<li><strong>Simple key/value method:</strong>
-
-	<code>$this->db->like('title', 'match');
-	<br /><br />// Produces: WHERE title LIKE '%match%'	</code>
-
-	<p>If you use multiple function calls they will be chained together with <var>AND</var> between them:</p>
-
-	<code>$this->db->like('title', 'match');<br />
-	$this->db->like('body', 'match');
-	<br /><br />
-	// WHERE title LIKE '%match%' AND  body LIKE '%match%</code>
-	If you want to control where the wildcard (%) is placed, you can use an optional third argument. Your options are 'before', 'after' and 'both' (which is the default).
-	<code>$this->db->like('title', 'match', 'before');
-	<br />
-		// Produces: WHERE title LIKE '%match'	<br />
-		<br />
-	$this-&gt;db-&gt;like('title', 'match', 'after'); <br />
-// Produces: WHERE title LIKE 'match%' <br />
-<br />
-	$this-&gt;db-&gt;like('title', 'match', 'both'); <br />
-// Produces: WHERE title LIKE '%match%' </code>	</li>
-
-If you do not want to use the wildcard (%) you can pass to the optional third argument the option 'none'.
-
-<code>
-	$this-&gt;db-&gt;like('title', 'match', 'none'); <br />
-// Produces: WHERE title LIKE 'match'
-</code>
-
-	<li><strong>Associative array method:</strong>
-
-	<code>
-	$array = array('title' => $match, 'page1' => $match, 'page2' => $match);<br /><br />
-
-	$this->db->like($array);
-	<br /><br />// WHERE title LIKE '%match%' AND  page1 LIKE '%match%' AND  page2 LIKE '%match%'</code></li>
-	</ol>
-
-
-<h2>$this->db->or_like();</h2>
-<p>This function is identical to the one above, except that multiple instances are joined by OR:</p>
-
-<code>
-$this->db->like('title', 'match');<br />
-$this->db->or_like('body', $match);
-<br />
-<br />// WHERE title LIKE '%match%' OR  body LIKE '%match%'</code>
-
-
-
-
-<p class="important">Note: or_like() was formerly known as orlike(), which has been removed.</p>
-<h2>$this-&gt;db-&gt;not_like();</h2>
-<p>This function is identical to <strong>like()</strong>, except that it generates NOT LIKE statements:</p>
-<code> $this-&gt;db-&gt;not_like('title', 'match');<br />
-<br />
-// WHERE title NOT LIKE '%match%</code>
-<h2>$this-&gt;db-&gt;or_not_like();</h2>
-<p>This function is identical to <strong>not_like()</strong>, except that multiple instances are joined by OR:</p>
-<code> $this-&gt;db-&gt;like('title', 'match');<br />
-$this-&gt;db-&gt;or_not_like('body', 'match'); <br />
-<br />
-// WHERE title  LIKE '%match% OR body NOT LIKE '%match%'</code>
-<h2>$this->db->group_by();</h2>
-<p>Permits you to write the GROUP BY portion of your query:</p>
-
-<code>$this->db->group_by("title");
-<br /><br />// Produces: GROUP BY title
-</code>
-
-<p>You can also pass an array of multiple values as well:</p>
-
-<code>$this->db->group_by(array("title", "date"));
-<br />
-<br />// Produces: GROUP BY title, date</code>
-
-<p class="important">Note: group_by() was formerly known as groupby(), which has been removed. </p>
-
-<h2> $this-&gt;db-&gt;distinct();<br />
-</h2>
-<p>Adds the &quot;DISTINCT&quot; keyword to  a query</p>
-<p><code>$this-&gt;db-&gt;distinct();<br />
-	$this-&gt;db-&gt;get('table');<br />
-		<br />
-	// Produces: SELECT DISTINCT * FROM table</code></p>
-<h2>$this->db->having();</h2>
-<p>Permits you to write the HAVING portion of your query. There are 2 possible syntaxes, 1 argument or 2:</p>
-
-<code>$this->db->having('user_id = 45');
-<br />
-// Produces: HAVING user_id = 45<br />
-<br />
-$this-&gt;db-&gt;having('user_id',  45); <br />
-// Produces: HAVING user_id = 45<br />
-<br />
-</code>
-
-<p>You can also pass an array of multiple values as well:</p>
-
-
-<p><code>$this->db->having(array('title =' => 'My Title', 'id <' => $id)); <br />
-		<br />
-	// Produces: HAVING title = 'My Title', id < 45</code></p>
-<p>If you are using a database that CodeIgniter escapes queries for, you can prevent escaping content by passing an optional third argument, and setting it to FALSE.</p>
-<p><code>$this-&gt;db-&gt;having('user_id',  45); <br />
-// Produces: HAVING `user_id` = 45 in some databases such as MySQL
-		<br />
-		$this-&gt;db-&gt;having('user_id',  45, FALSE); <br />
-// Produces: HAVING user_id = 45</code></p>
-<h2>$this-&gt;db-&gt;or_having();</h2>
-<p>Identical to having(), only separates multiple clauses with &quot;OR&quot;.</p>
-<h2>$this->db->order_by();</h2>
-<p>Lets you set an ORDER BY clause. The first parameter contains the name of the column you would like to order by.
-The second parameter lets you set the direction of the result.  Options are <kbd>asc</kbd> or <kbd>desc</kbd>, or <kbd>random</kbd>. </p>
-
-<code>$this->db->order_by("title", "desc");
-<br />
-<br />// Produces: ORDER BY title DESC
-</code>
-
-<p>You can also pass your own string in the first parameter:</p>
-
-<code>$this->db->order_by('title desc, name asc');
-<br />
-<br />// Produces: ORDER BY title DESC, name ASC
-</code>
-
-<p>Or multiple function calls can be made if you need multiple fields.</p>
-
-<p><code>$this->db->order_by("title", "desc");<br />
-	$this->db->order_by("name", "asc"); <br />
-	<br />
-	// Produces: ORDER BY title DESC, name ASC
-	</code></p>
-<p class="important">Note: order_by() was formerly known as orderby(), which has been removed.</p>
-<p class="important">Note: random ordering is not currently supported in Oracle or MSSQL drivers. These will default to 'ASC'.</p>
-<h2>$this->db->limit();</h2>
-<p>Lets you limit the number of rows you would like returned by the query:</p>
-
-<code>
-$this->db->limit(10);<br />
-<br />
-// Produces: LIMIT 10</code>
-
-
-<p>The second parameter lets you set a result offset.</p>
-
-<code>
-$this->db->limit(10, 20);<br />
-<br />
-// Produces: LIMIT 20, 10 (in MySQL.  Other databases have slightly different syntax)</code>
-
-
-<h2>$this->db->count_all_results();</h2>
-
-<p>Permits you to determine the number of rows in a particular Active Record query. Queries will accept Active Record restrictors such as where(),  or_where(), like(), or_like(), etc. Example:</p>
-<code>echo $this->db->count_all_results('<var>my_table</var>');<br />
-
-// Produces an integer, like 25<br />
-<br />
-$this-&gt;db-&gt;like('title', 'match');<br />
-$this-&gt;db-&gt;from('<var>my_table</var>');<br />
-echo $this-&gt;db-&gt;count_all_results();<br />
-// Produces an integer, like 17 </code>
-
-<h2>$this->db->count_all();</h2>
-
-<p>Permits you to determine the number of rows in a particular table.  Submit the table name in the first parameter. Example:</p>
-
-<code>echo $this->db->count_all('<var>my_table</var>');<br />
-<br />
-// Produces an integer, like 25</code>
-
-
-
-<a name="insert">&nbsp;</a>
-<h1>Inserting Data</h1>
-
-<h2>$this->db->insert();</h2>
-<p>Generates an insert string based on the data you supply, and runs the query. You can either pass an
-<strong>array</strong> or an <strong>object</strong> to the function.  Here is an example using an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
-&nbsp;&nbsp;&nbsp;'name' => 'My Name' ,<br />
-&nbsp;&nbsp;&nbsp;'date' => 'My date'<br />
-);<br />
-<br />
-$this->db->insert('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')</code>
-
-<p>The first parameter will contain the table name, the second is an associative array of values.</p>
-
-<p>Here is an example using an object:</p>
-
-<code>
-/*<br />
-&nbsp;&nbsp;&nbsp;&nbsp;class Myclass {<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $title = 'My Title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $content = 'My Content';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $date = 'My Date';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-*/<br />
-<br />
-$object = new Myclass;<br />
-<br />
-$this->db->insert('mytable', $object);
-<br /><br />
-// Produces: INSERT INTO mytable (title, content, date) VALUES ('My Title', 'My Content', 'My Date')</code>
-
-<p>The first parameter will contain the table name, the second is an object.</p>
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-<h2>$this->db->insert_batch();</h2>
-<p>Generates an insert string based on the data you supply, and runs the query. You can either pass an
-<strong>array</strong> or an <strong>object</strong> to the function.  Here is an example using an array:</p>
-
-<code> 
-$data = array(<br/>
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'My Name' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'My date'<br />
-&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'Another title' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'Another Name' ,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'Another date'<br />
-&nbsp;&nbsp;&nbsp;)<br/>
-);<br /> 
-<br />
-$this->db->update_batch('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'),  ('Another title', 'Another name', 'Another date')</code>
-
-<p>The first parameter will contain the table name, the second is an associative array of values.</p>
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-
-
-<h2>$this->db->set();</h2>
-<p>This function enables you to set values for <dfn>inserts</dfn> or <dfn>updates</dfn>.</p>
-
-<p><strong>It can be used instead of passing a data array directly to the insert or update functions:</strong> </p>
-
-<code>$this->db->set('name', $name);
-<br />
-$this->db->insert('mytable');
-<br /><br />
-// Produces: INSERT INTO mytable (name) VALUES ('{$name}')</code>
-
-<p>If you use multiple function called they will be assembled properly based on whether you are doing an insert or an update:</p>
-
-<code>$this-&gt;db-&gt;set('name', $name);<br />
-$this-&gt;db-&gt;set('title', $title);<br />
-$this-&gt;db-&gt;set('status', $status);<br />
-$this-&gt;db-&gt;insert('mytable'); </code>
-<p><strong>set()</strong> will also accept an optional third parameter ($escape), that will prevent data from being escaped if set to FALSE. To illustrate the difference, here is set() used both with and without the escape parameter.</p>
-<p><code>$this-&gt;db-&gt;set('field', 'field+1', FALSE);<br />
-	$this-&gt;db-&gt;insert('mytable'); <br />
-	// gives INSERT INTO mytable (field) VALUES (field+1)<br />
-	<br />
-	$this-&gt;db-&gt;set('field', 'field+1');<br />
-	$this-&gt;db-&gt;insert('mytable'); <br />
-	// gives INSERT INTO mytable (field) VALUES ('field+1')</code></p>
-<p>You can also pass an associative array to this function:</p>
-<code>
-$array = array('name' => $name, 'title' => $title, 'status' => $status);<br /><br />
-
-$this->db->set($array);<br />
-$this->db->insert('mytable');
-</code>
-
-<p>Or an object:</p>
-
-
-<code>
-/*<br />
-&nbsp;&nbsp;&nbsp;&nbsp;class Myclass {<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $title = 'My Title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $content = 'My Content';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $date = 'My Date';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-*/<br />
-<br />
-$object = new Myclass;<br />
-<br />
-$this->db->set($object);<br />
-$this->db->insert('mytable');
-</code>
-
-
-
-<a name="update">&nbsp;</a>
-<h1>Updating Data</h1>
-
-<h2>$this->db->update();</h2>
-<p>Generates an update string and runs the query based on the data you supply.  You can pass an
-<strong>array</strong> or an <strong>object</strong> to the function. Here is an example using
-an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => $title,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => $name,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => $date<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->db->where('id', $id);<br />
-$this->db->update('mytable', $data);
-<br /><br />
-// Produces:<br />
-// UPDATE mytable <br />
-// SET title = '{$title}', name = '{$name}', date = '{$date}'<br />
-// WHERE id = $id</code>
-
-<p>Or you can supply an object:</p>
-
-<code>
-/*<br />
-&nbsp;&nbsp;&nbsp;&nbsp;class Myclass {<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $title = 'My Title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $content = 'My Content';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $date = 'My Date';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-*/<br />
-<br />
-$object = new Myclass;<br />
-<br />
-$this->db->where('id', $id);<br />
-$this->db->update('mytable', $object);
-<br />
-<br />
-// Produces:<br />
-// UPDATE mytable <br />
-// SET title = '{$title}', name = '{$name}', date = '{$date}'<br />
-// WHERE id = $id</code>
-
-
-
-<p class="important"><strong>Note:</strong> All values are escaped automatically producing safer queries.</p>
-
-<p>You'll notice the use of the <dfn>$this->db->where()</dfn> function, enabling you to set the WHERE clause.
-You can optionally pass this information directly into the update function as a string:</p>
-
-<code>$this->db->update('mytable', $data, "id = 4");</code>
-
-<p>Or as an array:</p>
-
-<code>$this->db->update('mytable', $data, array('id' => $id));</code>
-
-<p>You may also use the <dfn>$this->db->set()</dfn> function described above when performing updates.</p>
-
-
-<a name="delete">&nbsp;</a>
-<h1>Deleting Data</h1>
-
-
-
-<h2>$this->db->delete();</h2>
-<p>Generates a delete SQL string and runs the query.</p>
-
-<code>
-$this->db->delete('mytable', array('id' => $id));
-<br /><br />
-// Produces:<br />
-// DELETE FROM mytable <br />
-// WHERE id = $id</code>
-
-<p>The first parameter is the table name, the second is the where clause. You can also use the <dfn>where()</dfn> or <dfn>or_where()</dfn> functions instead of passing
-the data to the second parameter of the function:</p>
-
-<p><code> $this->db->where('id', $id);<br />
-	$this->db->delete('mytable'); <br />
-	<br />
-	// Produces:<br />
-	// DELETE FROM mytable <br />
-	// WHERE id = $id</code></p>
-<p>An array of table names can be passed into delete() if you would like to delete data from more than 1 table.</p>
-<p><code>$tables = array('table1', 'table2', 'table3');<br />
-$this-&gt;db-&gt;where('id', '5');<br />
-$this-&gt;db-&gt;delete($tables);</code></p>
-<p>If you want to delete all data from a table, you can use the <dfn>truncate()</dfn> function, or <dfn>empty_table()</dfn>.</p>
-<h2>$this-&gt;db-&gt;empty_table();</h2>
-<p>Generates a delete SQL string and runs the query.<code>	$this-&gt;db-&gt;empty_table('mytable'); <br />
-	<br />
-// Produces<br />
-// DELETE FROM mytable</code></p>
-<h2>$this-&gt;db-&gt;truncate();</h2>
-<p>Generates a truncate SQL string and runs the query.</p>
-<code> $this-&gt;db-&gt;from('mytable'); <br />
-$this-&gt;db-&gt;truncate(); <br />
-// or <br />
-$this-&gt;db-&gt;truncate('mytable'); <br />
-<br />
-// Produce:<br />
-// TRUNCATE mytable <br />
-</code>
-<p class="important"><strong>Note:</strong> If the TRUNCATE command isn't available, truncate() will execute as &quot;DELETE FROM table&quot;.</p>
-
-<h1><a name="chaining">&nbsp;</a>Method Chaining</h1>
-
-<p>Method chaining allows you to simplify your syntax by connecting multiple functions.  Consider this example:</p>
-
-<code>
-<dfn>$this->db</dfn><kbd>-></kbd><var>select</var>('title')<kbd>-></kbd><var>from</var>('mytable')<kbd>-></kbd><var>where</var>('id', $id)<kbd>-></kbd><var>limit</var>(10, 20);<br />
-<br />
-$query = $this->db->get();</code>
-
-<p class="important"><strong>Note:</strong> Method chaining only works with PHP 5.</p>
-
-<p>&nbsp;</p>
-
-<h1><a name="caching">&nbsp;</a>Active Record Caching</h1>
-
-<p>While not &quot;true&quot; caching, Active Record enables you to save (or &quot;cache&quot;) certain parts of your queries for reuse at a later point in your script's execution. Normally, when an Active Record call is completed, all stored information is reset for the next call. With caching, you can prevent this reset, and reuse information easily.</p>
-
-<p>Cached calls are cumulative. If you make 2 cached select() calls, and then 2 uncached select() calls, this will result in 4 select() calls. There are three Caching functions available:</p>
-
-<h2>$this-&gt;db-&gt;start_cache()</h2>
-
-<p>This function must be called to begin caching. All Active Record queries of the correct type (see below for supported queries) are stored for later use.</p>
-
-<h2>$this-&gt;db-&gt;stop_cache()</h2>
-
-<p>This function can be called to stop caching.</p>
-
-<h2>$this-&gt;db-&gt;flush_cache()</h2>
-
-<p>This function deletes all items from the Active Record cache.</p>
-
-<p>Here's a usage example:</p>
-
-<p><code>$this-&gt;db-&gt;start_cache();<br />
-$this-&gt;db-&gt;select('field1');<br />
-$this-&gt;db-&gt;stop_cache();<br /><br />
-$this-&gt;db-&gt;get('tablename');<br />
-<br />
-//Generates: SELECT `field1` FROM (`tablename`)<br />
-<br />
-$this-&gt;db-&gt;select('field2');<br />
-$this-&gt;db-&gt;get('tablename');<br />
-<br />
-//Generates:  SELECT `field1`, `field2` FROM (`tablename`)<br />
-<br />
-$this-&gt;db-&gt;flush_cache();<br />
-<br />
-$this-&gt;db-&gt;select('field2');<br />
-$this-&gt;db-&gt;get('tablename');<br />
-<br />
-//Generates:  SELECT `field2` FROM (`tablename`)</code></p>
-
-<p class="important"> <strong>Note:</strong> The following statements can be cached: select, from, join, where, like, group_by, having, order_by, set</p>

-<h1>Database Caching Class</h1>
-
-<p>The Database Caching Class permits you to cache your queries as text files for reduced database load.</p>
-
-<p class="important"><strong>Important:</strong>&nbsp; This class is initialized automatically by the database driver
-when caching is enabled.  Do NOT load this class manually.<br /><br />
-
-<strong>Also note:</strong>&nbsp; Not all query result functions are available when you use caching. Please read this page carefully.</p>
-
-<h2>Enabling Caching</h2>
-
-<p>Caching is enabled in three steps:</p>
-
-<ul>
-<li>Create a writable directory on your server where the cache files can be stored.</li>
-<li>Set the path to your cache folder in your <dfn>application/config/database.php</dfn> file.</li>
-<li>Enable the caching feature, either globally by setting the preference in your <dfn>application/config/database.php</dfn> file, or manually as described below.</li>
-</ul>
-
-<p>Once enabled, caching will happen automatically whenever a page is loaded that contains database queries.</p>
-
-
-<h2>How Does Caching Work?</h2>
-
-<p>CodeIgniter's query caching system happens dynamically when your pages are viewed.
-When caching is enabled, the first time a web page is loaded, the query result object will
-be serialized and stored in a text file on your server. The next time the page is loaded the cache file will be used instead of
-accessing your database.  Your database usage can effectively be reduced to zero for any pages that have been cached.</p>
-
-<p>Only <dfn>read-type</dfn> (SELECT) queries can be cached, since these are the only type of queries that produce a result.
-<dfn>Write-type</dfn> (INSERT, UPDATE, etc.) queries, since they don't generate a result, will not be cached by the system.</p>
-
-<p>Cache files DO NOT expire.  Any queries that have been cached will remain cached until you delete them.  The caching system
-permits you clear caches associated with individual pages, or you can delete the entire collection of cache files.
-Typically you'll want to use the housekeeping functions described below to delete cache files after certain
-events take place, like when you've added new information to your database.</p>
-
-<h2>Will Caching Improve Your Site's Performance?</h2>
-
-<p>Getting a performance gain as a result of caching depends on many factors.
-If you have a highly optimized database under very little load, you probably won't see a performance boost.
-If your database is under heavy use you probably will see an improved response, assuming your file-system is not
-overly taxed.  Remember that caching simply changes how your information is retrieved, shifting it from being a database
-operation to a file-system one.</p>
-
-<p>In some clustered server environments, for example, caching may be detrimental since file-system operations are so intense.
-On single servers in shared environments, caching will probably be beneficial. Unfortunately there is no
-single answer to the question of whether you should cache your database.  It really depends on your situation.</p>
-
-<h2>How are Cache Files Stored?</h2>
-
-<p>CodeIgniter places the result of EACH query into its own cache file.  Sets of cache files are further organized into
-sub-folders corresponding to your controller functions.  To be precise, the sub-folders are named identically to the
-first two segments of your URI (the controller class name and function name).</p>
-
-<p>For example, let's say you have a controller called <dfn>blog</dfn> with a function called <dfn>comments</dfn> that
-contains three queries.  The caching system will create a cache folder
-called <kbd>blog+comments</kbd>, into which it will write three cache files.</p>
-
-<p>If you use dynamic queries that change based on information in your URI (when using pagination, for example), each instance of
-the query will produce its own cache file.  It's possible, therefore, to end up with many times more cache files than you have
-queries.</p>
-
-
-<h2>Managing your Cache Files</h2>
-
-<p>Since cache files do not expire, you'll need to build deletion routines into your application.  For example, let's say you have a blog
-that allows user commenting.  Whenever a new comment is submitted you'll want to delete the cache files associated with the
-controller function that serves up your comments.  You'll find two delete functions described below that help you
-clear data.</p>
-
-
-<h2>Not All Database Functions Work with Caching</h2>
-
-<p>Lastly, we need to point out that the result object that is cached is a simplified version of the full result object. For that reason,
-some of the query result functions are not available for use.</p>
-
-<p>The following functions <kbd>ARE NOT</kbd> available when using a cached result object:</p>
-
-<ul>
-<li>num_fields()</li>
-<li>field_names()</li>
-<li>field_data()</li>
-<li>free_result()</li>
-</ul>
-
-<p>Also, the two database resources (result_id and conn_id) are not available when caching, since result resources only
-pertain to run-time operations.</p>
-
-
-<br />
-
-<h1>Function Reference</h1>
-
-
-
-<h2>$this->db->cache_on()&nbsp; / &nbsp; $this->db->cache_off()</h2>
-
-<p>Manually enables/disables caching.  This can be useful if you want to
-keep certain queries from being cached.  Example:</p>
-
-<code>
-// Turn caching on<br />
-$this->db->cache_on();<br />
-$query = $this->db->query("SELECT * FROM mytable");<br />
-<br />
-// Turn caching off for this one query<br />
-$this->db->cache_off();<br />
-$query = $this->db->query("SELECT * FROM members WHERE member_id = '$current_user'");<br />
-<br />
-// Turn caching back on<br />
-$this->db->cache_on();<br />
-$query = $this->db->query("SELECT * FROM another_table");
-</code>
-
-
-<h2>$this->db->cache_delete()</h2>
-
-<p>Deletes the cache files associated with a particular page. This is useful if you need to clear caching after you update your database.</p>
-
-<p>The caching system saves your cache files to folders that correspond to the URI of the page you are viewing.  For example, if you are viewing
-a page at <dfn>example.com/index.php/blog/comments</dfn>, the caching system will put all cache files associated with it in a folder
-called <dfn>blog+comments</dfn>.  To delete those particular cache files you will use:</p>
-
-<code>$this->db->cache_delete('blog', 'comments');</code>
-
-<p>If you do not use any parameters the current URI will be used when determining what should be cleared.</p>
-
-
-<h2>$this->db->cache_delete_all()</h2>
-
-<p>Clears all existing cache files.  Example:</p>
-
-<code>$this->db->cache_delete_all();</code>
-

-<h1>Custom Function Calls</h1>
-
-<h2>$this->db->call_function();</h2>
-
-<p>This function enables you to call PHP database functions that are not natively included in CodeIgniter, in a platform independent manner.
-For example, lets say you want to call the <dfn>mysql_get_client_info()</dfn> function, which is <strong>not</strong> natively supported
-by CodeIgniter.  You could do so like this:
-</p>
-
-<code>$this->db->call_function('<var>get_client_info</var>');</code>
-
-<p>You must supply the name of the function, <strong>without</strong> the <var>mysql_</var> prefix, in the first parameter.  The prefix is added
-automatically based on which database driver is currently being used.  This permits you to run the same function on different database platforms.
-Obviously not all function calls are identical between platforms, so there are limits to how useful this function can be in terms of portability.</p>
-
-<p>Any parameters needed by the function you are calling will be added to the second parameter.</p>
-
-<code>$this->db->call_function('<var>some_function</var>', $param1, $param2, etc..);</code>
-
-
-<p>Often, you will either need to supply a database connection ID or a database result ID.  The connection ID can be accessed using:</p>
-
-<code>$this->db->conn_id;</code>
-
-<p>The result ID can be accessed from within your result object, like this:</p>
-
-<code>$query = $this->db->query("SOME QUERY");<br />
-<br />
-<var>$query->result_id;</var></code>

-<h1>Database Configuration</h1>
-
-<p>CodeIgniter has a config file that lets you store your database connection values (username, password, database name, etc.).
-The config file is located at <samp>application/config/database.php</samp>. You can also set database connection values for specific <a href="../libraries/config.html">environments</a> by placing <strong>database.php</strong> it the respective environment config folder.</p>
-
-<p>The config settings are stored in a multi-dimensional array with this prototype:</p>
-
-<code>$db['default']['hostname'] = "localhost";<br />
-$db['default']['username'] = "root";<br />
-$db['default']['password'] = "";<br />
-$db['default']['database'] = "database_name";<br />
-$db['default']['dbdriver'] = "mysql";<br />
-$db['default']['dbprefix'] = "";<br />
-$db['default']['pconnect'] = TRUE;<br />
-$db['default']['db_debug'] = FALSE;<br />
-$db['default']['cache_on'] = FALSE;<br />
-$db['default']['cachedir'] =  &quot;&quot;;<br />
-$db['default']['char_set'] = "utf8";<br />
-$db['default']['dbcollat'] = "utf8_general_ci";<br />
-$db['default']['swap_pre'] = "";<br />
-$db['default']['autoinit'] = TRUE;<br />
-$db['default']['stricton'] = FALSE;</code>
-
-<p>The reason we use a multi-dimensional array rather than a more simple one is to permit you to optionally store
-multiple sets of connection values.  If, for example,  you run multiple environments (development, production, test, etc.)
-under a single installation, you can set up a connection group for each, then switch between groups as needed.
-For example, to set up a "test" environment you would do this:</p>
-
-<code>$db['test']['hostname'] = "localhost";<br />
-$db['test']['username'] = "root";<br />
-$db['test']['password'] = "";<br />
-$db['test']['database'] = "database_name";<br />
-$db['test']['dbdriver'] = "mysql";<br />
-$db['test']['dbprefix'] = "";<br />
-$db['test']['pconnect'] = TRUE;<br />
-$db['test']['db_debug'] = FALSE;<br />
-$db['test']['cache_on'] = FALSE;<br />
-$db['test']['cachedir'] =  &quot;&quot;;<br />
-$db['test']['char_set'] = "utf8";<br />
-$db['test']['dbcollat'] = "utf8_general_ci";<br />
-$db['test']['swap_pre'] = "";<br />
-$db['test']['autoinit'] = TRUE;<br />
-$db['test']['stricton'] = FALSE;</code>
-
-
-<p>Then, to globally tell the system to use that group you would set this variable located in the config file:</p>
-
-<code>$active_group = "test";</code>
-
-<p>Note: The name "test" is arbitrary.  It can be anything you want. By default we've used the word "default"
-for the primary connection, but it too can be renamed to something more relevant to your project.</p>
-
-<h3>Active Record</h3>
-
-<p>The <a href="active_record.html">Active Record Class</a> is globally enabled or disabled by setting the $active_record variable in the database configuration file to TRUE/FALSE (boolean). If you are not using the active record class, setting it to FALSE will utilize fewer resources when the database classes are initialized.</p>
-
-<code>$active_record = TRUE;</code>
-
-<p class="important"><strong>Note:</strong> that some CodeIgniter classes such as Sessions require Active Records be enabled to access certain functionality.</p>
-
-<h3>Explanation of Values:</h3>
-
-<ul>
-<li><strong>hostname</strong> - The hostname of your database server. Often this is "localhost".</li>
-<li><strong>username</strong> - The username used to connect to the database.</li>
-<li><strong>password</strong> - The password used to connect to the database.</li>
-<li><strong>database</strong> - The name of the database you want to connect to.</li>
-<li><strong>dbdriver</strong> - The database type. ie: mysql, postgres, odbc, etc. Must be specified in lower case.</li>
-<li><strong>dbprefix</strong> - An optional table prefix which will added to the table name when running <a href="active_record.html">Active Record</a> queries.  This permits multiple CodeIgniter installations to share one database.</li>
-<li><strong>pconnect</strong> - TRUE/FALSE (boolean) - Whether to use a persistent connection.</li>
-<li><strong>db_debug</strong> - TRUE/FALSE (boolean) - Whether database errors should be displayed.</li>
-<li><strong>cache_on</strong> - TRUE/FALSE (boolean) - Whether database query caching is enabled, see also <a href="caching.html">Database Caching Class</a>.</li>
-<li><strong>cachedir</strong> - The absolute server path to your database query cache directory.</li>
-<li><strong>char_set</strong> - The character set used in communicating with the database.</li>
-<li><strong>dbcollat</strong> - The character collation used in communicating with the database. <p class="important"><strong>Note:</strong> For MySQL and MySQLi databases, this setting is only used as a backup if your server is running PHP &lt; 5.2.3 or MySQL &lt; 5.0.7 (and in table creation queries made with DB Forge). There is an incompatibility in PHP with mysql_real_escape_string() which can make your site vulnerable to SQL injection if you are using a multi-byte character set and are running versions lower than these. Sites using Latin-1 or UTF-8 database character set and collation are unaffected.</p></li>
-<li><strong>swap_pre</strong> - A default table prefix that should be swapped with <var>dbprefix</var>. This is useful for distributed applications where you might run manually written queries, and need the prefix to still be customizable by the end user.</li>
-<li><strong>autoinit</strong> - Whether or not to automatically connect to the database when the library loads. If set to false, the connection will take place prior to executing the first query.</li>
-<li><strong>stricton</strong> - TRUE/FALSE (boolean) - Whether to force "Strict Mode" connections, good for ensuring strict SQL while developing an application.</li>
-<li><strong>port</strong> - The database port number.  To use this value you have to add a line to the database config array.<code>$db['default']['port'] =  5432;</code>
-</ul>
-
-<p class="important"><strong>Note:</strong> Depending on what database platform you are using (MySQL, Postgres, etc.)
-not all values will be needed.  For example, when using SQLite you will not need to supply a username or password, and
-the database name will be the path to your database file. The information above assumes you are using MySQL.</p>

-<h1>Connecting to your Database</h1>
-
-<p>There are two ways to connect to a database:</p>
-
-<h2>Automatically Connecting</h2>
-
-<p>The "auto connect" feature will load and instantiate the database class with every page load.
-To enable "auto connecting", add the word <var>database</var> to the library array, as indicated in the following file:</p>
-
-<p><kbd>application/config/autoload.php</kbd></p>
-
-<h2>Manually Connecting</h2>
-
-<p>If only some of your pages require database connectivity you can manually connect to your database by adding this
-line of code in any function where it is needed, or in your class constructor to make the database
-available globally in that class.</p>
-
-<code>$this->load->database();</code>
-
-<p class="important">If the above function does <strong>not</strong> contain any information in the first parameter it will connect
-to the group specified in your database config file. For most people, this is the preferred method of use.</p>
-
-<h3>Available Parameters</h3>
-
-<ol>
-	<li>The database connection values, passed either as an array or a DSN string.</li>
-	<li>TRUE/FALSE (boolean).  Whether to return the connection ID (see Connecting to Multiple Databases below).</li>
-	<li>TRUE/FALSE (boolean).  Whether to enable the Active Record class.  Set to TRUE by default.</li>
-</ol>
-
-
-<h3>Manually Connecting to a Database</h3>
-
-<p>The first parameter of this function can <strong>optionally</strong> be used to specify a particular database group
-from your config file, or you can even submit connection values for a database that is not specified in your config file.
-Examples:</p>
-
-<p>To choose a specific group from your config file you can do this:</p>
-
-<code>$this->load->database('<samp>group_name</samp>');</code>
-
-<p>Where <samp>group_name</samp> is the name of the connection group from your config file.</p>
-
-
-<p>To connect manually to a desired database you can pass an array of values:</p>
-
-<code>$config['hostname'] = "localhost";<br />
-$config['username'] = "myusername";<br />
-$config['password'] = "mypassword";<br />
-$config['database'] = "mydatabase";<br />
-$config['dbdriver'] = "mysql";<br />
-$config['dbprefix'] = "";<br />
-$config['pconnect'] = FALSE;<br />
-$config['db_debug'] = TRUE;<br />
-$config['cache_on'] = FALSE;<br />
-$config['cachedir'] = "";<br />
-$config['char_set'] = "utf8";<br />
-$config['dbcollat'] = "utf8_general_ci";<br />
-<br />
-$this->load->database(<samp>$config</samp>);</code>
-
-<p>For information on each of these values please see the <a href="configuration.html">configuration page</a>.</p>
-
-<p>Or you can submit your database values as a Data Source Name. DSNs must have this prototype:</p>
-
-<code>$dsn = 'dbdriver://username:password@hostname/database';<br />
-<br />
-$this->load->database(<samp>$dsn</samp>);</code>
-
-<p>To override default config values when connecting with a DSN string, add the config variables as a query string.</p>
-
-<code>$dsn = 'dbdriver://username:password@hostname/database?char_set=utf8&amp;dbcollat=utf8_general_ci&amp;cache_on=true&amp;cachedir=/path/to/cache';<br />
-<br />
-$this->load->database(<samp>$dsn</samp>);</code>
-
-<h2>Connecting to Multiple Databases</h2>
-
-<p>If you need to connect to more than one database simultaneously you can do so as follows:</p>
-
-
-<code>$DB1 = $this->load->database('group_one', TRUE);<br />
-$DB2 = $this->load->database('group_two', TRUE);
-</code>
-
-<p>Note: Change the words "group_one" and "group_two" to the specific group names you are connecting to (or
-you can pass the connection values as indicated above).</p>
-
-<p>By setting the second parameter to TRUE (boolean) the function will return the database object.</p>
-
-<div class="important">
-<p>When you connect this way, you will use your object name to issue commands rather than the syntax used throughout this guide.  In other words, rather than issuing commands with:</p>
-
-<p>$this->db->query();<br />$this->db->result();<br /> etc...</p>
-
-<p>You will instead use:</p>
-
-<p>$DB1->query();<br />$DB1->result();<br /> etc...</p>
-
-</div>
-
-<h2>Reconnecting / Keeping the Connection Alive</h2>
-
-<p>If the database server's idle timeout is exceeded while you're doing some heavy PHP lifting (processing an image, for instance), you should consider pinging the server by using the <dfn>reconnect()</dfn> method before sending further queries, which can gracefully keep the connection alive or re-establish it.</p>
-
-<code>$this->db->reconnect();</code>
-
-<h2>Manually closing the Connection</h2>
-
-<p>While CodeIgniter intelligently takes care of closing your database connections, you can explicitly close the connection.</p>
-
-<code>$this->db->close();</code>

-<h1>Database Quick Start: Example Code</h1>
-
-<p>The following page contains example code showing how the database class is used.  For complete details please
-read the individual pages describing each function.</p>
-
-
-<h2>Initializing the Database Class</h2>
-
-<p>The following code loads and initializes the database class based on your <a href="configuration.html">configuration</a> settings:</p>
-
-<code>$this->load->database();</code>
-
-<p>Once loaded the class is ready to be used as described below.</p>
-
-<p>Note: If all your pages require database access you can connect automatically.  See the <a href="connecting.html">connecting</a> page for details.</p>
-
-
-<h2>Standard Query With Multiple Results (Object Version)</h2>
-
-<code>$query = $this->db->query('SELECT name, title, email FROM my_table');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->email;<br />
-}<br />
-<br />
-echo 'Total Results: ' . $query->num_rows();
-</code>
-
-<p>The above <dfn>result()</dfn> function returns an array of <strong>objects</strong>.  Example:  $row->title</p>
-
-
-<h2>Standard Query With Multiple Results (Array Version)</h2>
-
-<code>$query = $this->db->query('SELECT name, title, email FROM my_table');<br />
-<br />
-foreach ($query->result_array() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row['title'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row['name'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row['email'];<br />
-}</code>
-
-<p>The above <dfn>result_array()</dfn> function returns an array of standard array indexes.  Example:  $row['title']</p>
-
-
-<h2>Testing for Results</h2>
-
-<p>If you run queries that might <strong>not</strong> produce a result, you are encouraged to test for a result first
-using the <dfn>num_rows()</dfn> function:</p>
-
-<code>
-$query = $this->db->query("YOUR QUERY");<br />
-<br />
-if ($query->num_rows() > 0)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;foreach ($query->result() as $row)<br />
-&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->body;<br />
-&nbsp;&nbsp;&nbsp;}<br />
-}
-</code>
-
-
-
-
-<h2>Standard Query With Single Result</h2>
-
-<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
-<br />
-$row = $query->row();<br />
-echo $row->name;<br />
-</code>
-
-<p>The above <dfn>row()</dfn> function returns an <strong>object</strong>.  Example:  $row->name</p>
-
-
-<h2>Standard Query With Single Result (Array version)</h2>
-
-<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
-<br />
-$row = $query->row_array();<br />
-echo $row['name'];<br />
-</code>
-
-<p>The above <dfn>row_array()</dfn> function returns an <strong>array</strong>.  Example:  $row['name']</p>
-
-
-<h2>Standard Insert</h2>
-
-<code>
-$sql = "INSERT INTO mytable (title, name) <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VALUES (".$this->db->escape($title).", ".$this->db->escape($name).")";<br />
-<br />
-$this->db->query($sql);<br />
-<br />
-echo $this->db->affected_rows();
-</code>
-
-
-
-
-<h2>Active Record Query</h2>
-
-<p>The <a href="active_record.html">Active Record Pattern</a> gives you a simplified means of retrieving data:</p>
-
-<code>
-$query = $this->db->get('table_name');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-}</code>
-
-<p>The above <dfn>get()</dfn> function retrieves all the results from the supplied table.
-The <a href="active_record.html">Active Record</a> class contains a full compliment of functions
-for working with data.</p>
-
-
-<h2>Active Record Insert</h2>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => $title,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => $name,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => $date<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->db->insert('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('{$title}', '{$name}', '{$date}')</code>

-<h1>Field Data</h1>
-
-
-<h2>$this->db->list_fields()</h2>
-<p>Returns an array containing the field names. This query can be called two ways:</p>
-
-
-<p>1. You can supply the table name and call it from the <dfn>$this->db-></dfn> object:</p>
-
-<code>
-$fields = $this->db->list_fields('table_name');<br /><br />
-
-foreach ($fields as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field;<br />
-}
-</code>
-
-<p>2. You can gather the field names associated with any query you run by calling the function
-from your query result object:</p>
-
-<code>
-$query = $this->db->query('SELECT * FROM some_table');
-<br /><br />
-
-foreach ($query->list_fields() as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field;<br />
-}
-</code>
-
-
-<h2>$this->db->field_exists()</h2>
-
-<p>Sometimes it's helpful to know whether a particular field exists before performing an action.
-Returns a boolean TRUE/FALSE.  Usage example:</p>
-
-<code>
-if ($this->db->field_exists('field_name', 'table_name'))<br />
-{<br />
-&nbsp;&nbsp; // some code...<br />
-}
-</code>
-
-<p>Note:  Replace <em>field_name</em> with the name of the column you are looking for, and replace
-<em>table_name</em> with the name of the table you are looking for.</p>
-
-
-<h2>$this->db->field_data()</h2>
-<p>Returns an array of objects containing field information.</p>
-<p>Sometimes it's helpful to gather the field names or other metadata, like the column type, max length, etc.</p>
-
-
-<p class="important">Note: Not all databases provide meta-data.</p>
-
-<p>Usage example:</p>
-
-<code>
-$fields = $this->db->field_data('table_name');<br /><br />
-
-foreach ($fields as $field)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $field->name;<br />
-&nbsp;&nbsp;&nbsp;echo $field->type;<br />
-&nbsp;&nbsp;&nbsp;echo $field->max_length;<br />
-&nbsp;&nbsp;&nbsp;echo $field->primary_key;<br />
-}
-</code>
-
-<p>If you have run a query already you can use the result object instead of supplying the table name:</p>
-
-<code>
-$query = $this->db->query("YOUR QUERY");<br />
-$fields = $query->field_data();
-</code>
-
-
-<p>The following data is available from this function if supported by your database:</p>
-
-<ul>
-<li>name - column name</li>
-<li>max_length - maximum length of the column</li>
-<li>primary_key - 1 if the column is a primary key</li>
-<li>type - the type of the column</li>
-</ul>

-<h2><a name="init"></a>Initializing the Forge Class</h2>
-
-<p class="important"><strong>Important:</strong>&nbsp; In order to initialize the Forge class, your database driver must
-already be running, since the forge class relies on it.</p>
-
-<p>Load the Forge Class as follows:</p>
-
-<code>$this->load->dbforge()</code>
-
-<p>Once initialized you will access the functions using the <dfn>$this->dbforge</dfn> object:</p>
-
-<code>$this->dbforge->some_function()</code>
-<h2><a name="create"></a>$this->dbforge->create_database('db_name')</h2>
-
-<p>Permits you to create the database specified in the first parameter. Returns TRUE/FALSE based on success or failure:</p>
-
-<code>if ($this->dbforge->create_database('my_db'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo 'Database created!';<br />
-}</code>
-
-
-
-
-<h2><a name="drop"></a>$this->dbforge->drop_database('db_name')</h2>
-
-<p>Permits you to drop the database specified in the first parameter. Returns TRUE/FALSE based on success or failure:</p>
-
-<code>if ($this->dbforge->drop_database('my_db'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo 'Database deleted!';<br />
-}</code>
-
-
-<h1>Creating and Dropping Tables</h1>
-<p>There are several things you may wish to do when creating tables. Add fields, add keys to the table, alter columns. CodeIgniter provides a mechanism for this.</p>
-<h2><a name="add_field" id="add_field"></a>Adding fields</h2>
-<p>Fields are created via an associative array. Within the array you must include a 'type' key that relates to the datatype of the field. For example, INT, VARCHAR, TEXT, etc. Many datatypes (for example VARCHAR) also require a 'constraint' key.</p>
-<p><code>$fields = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'users' =&gt; array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'VARCHAR',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'constraint' =&gt; '100',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-	<br />
-// will translate to &quot;users VARCHAR(100)&quot; when the field is added.</code></p>
-<p>Additionally, the following key/values can be used:</p>
-<ul>
-	<li>unsigned/true : to generate &quot;UNSIGNED&quot; in the field definition.</li>
-	<li>default/value : to generate a default value in the field definition.</li>
-	<li>null/true : to generate &quot;NULL&quot; in the field definition. Without this, the field will default to &quot;NOT NULL&quot;.</li>
-	<li>auto_increment/true : generates an auto_increment flag on the field. Note that the field type must be a type that supports this, such as integer.</li>
-	</ul>
-<p><code>$fields = array(<br />

-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'TEXT',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'null' =&gt; TRUE,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-</code></p>
-<p>After the fields have been defined, they can  be added  using <dfn>$this-&gt;dbforge-&gt;add_field($fields);</dfn> followed by a call to the <dfn>create_table()</dfn> function.</p>
-<h3>$this-&gt;dbforge-&gt;add_field()</h3>
-<p>The add fields function will accept the above array.</p>
-<h3>Passing strings as fields</h3>
-<p>If you know exactly how you want a field to be created, you can pass the string into the field definitions with add_field()</p>
-<p><code>$this-&gt;dbforge-&gt;add_field(&quot;label varchar(100) NOT NULL DEFAULT 'default label'&quot;);</code></p>
-<p class="important">Note: Multiple calls to <dfn>add_field()</dfn> are cumulative.</p>
-<h3>Creating an id field</h3>
-<p>There is a special exception for creating id fields. A field with type id will automatically be assinged as an INT(9) auto_incrementing Primary Key.</p>
-<p><code>$this-&gt;dbforge-&gt;add_field('id');<br />
-	// gives id INT(9) NOT NULL AUTO_INCREMENT</code></p>
-<h2><a name="add_key" id="add_key"></a>Adding Keys</h2>
-<p>Generally speaking, you'll want your table to have Keys. This is accomplished with <dfn>$this-&gt;dbforge-&gt;add_key('field')</dfn>. An optional second parameter set to TRUE will make it a primary key. Note that <dfn>add_key()</dfn> must be followed by a call to <dfn>create_table()</dfn>.</p>
-<p>Multiple column non-primary keys must be sent as an array.  Sample output below is for MySQL.</p>
-<p><code>$this-&gt;dbforge-&gt;add_key('blog_id', TRUE);<br />
-	// gives PRIMARY KEY `blog_id` (`blog_id`)<br />
-	<br />
-	$this-&gt;dbforge-&gt;add_key('blog_id', TRUE);<br />
-	$this-&gt;dbforge-&gt;add_key('site_id', TRUE);<br />
-	// gives PRIMARY KEY `blog_id_site_id` (`blog_id`, `site_id`)<br />
-	<br />
-	$this-&gt;dbforge-&gt;add_key('blog_name');<br />
-	// gives KEY `blog_name` (`blog_name`)<br />
-	<br />
-	$this-&gt;dbforge-&gt;add_key(array('blog_name', 'blog_label'));<br />
-	// gives KEY `blog_name_blog_label` (`blog_name`, `blog_label`)</code></p>
-<h2><a name="create_table" id="create_table"></a>Creating a table</h2>
-<p>After fields and keys have been declared, you can create a new table with</p>
-<p><code>$this-&gt;dbforge-&gt;create_table('table_name');<br />
-// gives CREATE TABLE table_name</code></p>
-<p>An optional second parameter set to TRUE adds an &quot;IF NOT EXISTS&quot; clause into the definition</p>
-<p><code>$this-&gt;dbforge-&gt;create_table('table_name', TRUE);<br />
-// gives CREATE TABLE IF NOT EXISTS table_name</code></p>
-<h2><a name="drop_table" id="drop_table"></a>Dropping a table</h2>
-<p>Executes a DROP TABLE sql</p>
-<p><code>$this-&gt;dbforge-&gt;drop_table('table_name');<br />
-	// gives DROP TABLE IF EXISTS  table_name</code></p>
-<h2><a name="rename_table" id="rename_table"></a>Renaming a table</h2>
-<p>Executes a TABLE rename</p>
-<p><code>$this-&gt;dbforge-&gt;rename_table('old_table_name', 'new_table_name');<br />
-	// gives ALTER TABLE old_table_name RENAME TO new_table_name</code></p>
-<h1><a name="modifying_tables" id="modifying_tables"></a>Modifying Tables</h1>
-<h2>$this-&gt;dbforge-&gt;add_column()</h2>
-<p>The add_column() function is used to modify an existing table. It accepts the same field array as above, and can be used for an unlimited number of additional fields.</p>
-<p><code>$fields = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'preferences' =&gt; array('type' =&gt; 'TEXT')<br />
-);<br />
-$this-&gt;dbforge-&gt;add_column('table_name', $fields);<br />
-<br />
-// gives ALTER TABLE table_name ADD   	preferences TEXT</code></p>
-<h2>$this-&gt;dbforge-&gt;drop_column()</h2>
-<p>Used to remove a column from a table. </p>
-<p><code>$this-&gt;dbforge-&gt;drop_column('table_name', 'column_to_drop');</code></p>
-<h2>$this-&gt;dbforge-&gt;modify_column()</h2>
-<p>The usage of this function is identical to add_column(), except it alters an existing column rather than adding a new one. In order to change the name you can add a &quot;name&quot; key into the field defining array.</p>
-<p><code>$fields = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'old_name' =&gt; array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' =&gt; 'new_name',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'TEXT',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-);<br />
-$this-&gt;dbforge-&gt;modify_column('table_name', $fields);<br />
-	<br />
-	// gives ALTER TABLE table_name CHANGE   	old_name new_name TEXT </code></p>

-<h1>Query Helper Functions</h1>
-
-
-<h2>$this->db->insert_id()</h2>
-<p>The insert ID number when performing database inserts.</p>
-
-<h2>$this->db->affected_rows()</h2>
-<p>Displays the number of affected rows, when doing "write" type queries (insert, update, etc.).</p>
-<p>Note:  In MySQL "DELETE FROM TABLE" returns 0 affected rows. The database class has a small hack that allows it to return the
-correct number of affected rows.  By default this hack is enabled but it can be turned off in the database driver file.</p>
-
-
-<h2>$this->db->count_all();</h2>
-<p>Permits you to determine the number of rows in a particular table.  Submit the table name in the first parameter. Example:</p>
-<code>echo $this->db->count_all('<var>my_table</var>');<br />
-<br />
-// Produces an integer, like 25
-</code>
-
-
-<h2>$this->db->platform()</h2>
-<p>Outputs the database platform you are running (MySQL, MS SQL, Postgres, etc...):</p>
-<code>echo $this->db->platform();</code>
-
-
-<h2>$this->db->version()</h2>
-<p>Outputs the database version you are running:</p>
-<code>echo $this->db->version();</code>
-
-
-<h2>$this->db->last_query();</h2>
-<p>Returns the last query that was run (the query string, not the result).  Example:</p>
-
-<code>$str = $this->db->last_query();<br />
-<br />
-// Produces:  SELECT * FROM sometable....
-</code>
-
-
-<p>The following two functions help simplify the process of writing database INSERTs and UPDATEs.</p>
-
-
-<h2>$this->db->insert_string(); </h2>
-<p>This function simplifies the process of writing database inserts. It returns a correctly formatted SQL insert string. Example:</p>
-
-<code>$data = array('name' => $name, 'email' => $email, 'url' => $url);<br />
-<br />
-$str = $this->db->insert_string('table_name', $data);
-</code>
-
-<p>The first parameter is the table name, the second is an associative array with the data to be inserted.  The above example produces:</p>
-<code>INSERT INTO table_name (name, email, url) VALUES ('Rick', 'rick@example.com', 'example.com')</code>
-
-<p class="important">Note: Values are automatically escaped, producing safer queries.</p>
-
-
-
-<h2>$this->db->update_string(); </h2>
-<p>This function simplifies the process of writing database updates. It returns a correctly formatted SQL update string. Example:</p>
-
-<code>$data = array('name' => $name, 'email' => $email, 'url' => $url);<br />
-<br />
-$where = "author_id = 1 AND status = 'active'";
-<br /><br />
-$str = $this->db->update_string('table_name', $data, $where);
-</code>
-
-<p>The first parameter is the table name, the second is an associative array with the data to be updated, and the third parameter is the "where" clause. The above example produces:</p>
-<code> UPDATE table_name SET name = 'Rick', email = 'rick@example.com', url = 'example.com' WHERE author_id = 1 AND status = 'active'</code>
-
-<p class="important">Note: Values are automatically escaped, producing safer queries.</p>

-<h1>Queries</h1>
-
-<h2>$this->db->query();</h2>
-
-<p>To submit a query, use the following function:</p>
-
-<code>$this->db->query('YOUR QUERY HERE');</code>
-
-<p>The <dfn>query()</dfn> function returns a database result <strong>object</strong> when "read" type queries are run,
-which you can use to <a href="results.html">show your results</a>.  When "write" type queries are run it simply returns TRUE or FALSE
-depending on success or failure.  When retrieving data you will typically assign the query to your own variable, like this:</p>
-
-<code><var>$query</var> = $this->db->query('YOUR QUERY HERE');</code>
-
-<h2>$this->db->simple_query();</h2>
-
-<p>This is a simplified version of the <dfn>$this->db->query()</dfn> function.  It ONLY returns TRUE/FALSE on success or failure.
-It DOES NOT return a database result set, nor does it set the query timer, or compile bind data, or store your query for debugging.
-It simply lets you submit a query. Most users will rarely use this function.</p>
-
-
-<h1>Working with Database prefixes manually</h1>
-<p>If you have configured a database prefix and would like to prepend it to a table name for use in a native SQL query for example, then you can use the following:</p>
-<p><code>$this-&gt;db-&gt;dbprefix('tablename');<br />
-// outputs prefix_tablename</code></p>
-
-<p>If for any reason you would like to change the prefix programatically without needing to create a new connection, you can use this method:</p>
-<p><code>$this-&gt;db-&gt;set_dbprefix('newprefix');<br /><br />
-$this-&gt;db-&gt;dbprefix('tablename');<br />
-// outputs newprefix_tablename</code></p>
-
-
-<h1>Protecting identifiers</h1>
-<p>In many databases it is advisable to protect table and field names - for example with backticks in MySQL. <strong>Active Record queries are automatically protected</strong>, however if you need to manually protect an identifier you can use:</p>
-<p><code>$this-&gt;db-&gt;protect_identifiers('table_name');</code></p>
-
-<p>This function will also add a table prefix to your table, assuming you have a prefix specified in your database config file. To enable the prefixing set <kbd>TRUE</kbd> (boolen) via the second parameter:</p>
-<p><code>$this-&gt;db-&gt;protect_identifiers('table_name', <kbd>TRUE</kbd>);</code></p>
-
-
-<h1>Escaping Queries</h1>
-<p>It's a very good security practice to escape your data before submitting it into your database.
-CodeIgniter has three methods that help you do this:</p>
-
-<ol>
-<li><strong>$this->db->escape()</strong> This function determines the data type so that it
-can escape only string data.  It also automatically adds single quotes around the data so you don't have to:
-
-<code>$sql = "INSERT INTO table (title) VALUES(".$this->db->escape($title).")";</code></li>
-
-<li><strong>$this->db->escape_str()</strong>  This function escapes the data passed to it, regardless of type.
-Most of the time you'll use the above function rather than this one. Use the function like this:
-
-<code>$sql = "INSERT INTO table (title) VALUES('".$this->db->escape_str($title)."')";</code></li>
-
-<li><strong>$this->db->escape_like_str()</strong>  This method should be used when strings are to be used in LIKE
-conditions so that LIKE wildcards ('%', '_') in the string are also properly escaped.
-
-<code>$search = '20% raise';<br />
-$sql = "SELECT id FROM table WHERE column LIKE '%".$this->db->escape_like_str($search)."%'";</code></li>
-
-</ol>
-
-
-<h1>Query Bindings</h1>
-
-
-<p>Bindings enable you to simplify your query syntax by letting the system put the queries together for you. Consider the following example:</p>
-
-<code>
-$sql = "SELECT * FROM some_table WHERE id = <var>?</var> AND status = <var>?</var> AND author = <var>?</var>";
-<br /><br />
-$this->db->query($sql, array(3, 'live', 'Rick'));
-</code>
-
-<p>The question marks in the query are automatically replaced with the values in the array in the second parameter of the query function.</p>
-<p class="important">The secondary benefit of using binds is that the values are automatically escaped, producing safer queries.  You don't have to remember to manually escape data; the engine does it automatically for you.</p>

-<h1>Generating Query Results</h1>
-
-
-<p>There are several ways to generate query results:</p>
-
-	<h2>result()</h2>
-
-	<p>This function returns the query result as an array of <strong>objects</strong>, or <strong>an empty array</strong> on failure.
-
-	Typically you'll use this in a foreach loop, like this:</p>
-
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	foreach ($query->result() as $row)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-	&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-	&nbsp;&nbsp;&nbsp;echo $row->body;<br />
-	}</code>
-
-	<p>The above <dfn>function</dfn> is an alias of <dfn>result_object()</dfn>.</p>
-
-	<p>If you run queries that might <strong>not</strong> produce a result, you are encouraged to test the result first:</p>
-
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	if ($query->num_rows() > 0)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;foreach ($query->result() as $row)<br />
-	&nbsp;&nbsp;&nbsp;{<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->body;<br />
-	&nbsp;&nbsp;&nbsp;}<br />
-	}
-	</code>
-
-	<p>You can also pass a string to result() which represents a class to instantiate for each result object (note: this class must be loaded)</p>
-
-	<code>
-	$query = $this->db->query("SELECT * FROM users;");<br />
-	<br />
-	foreach ($query->result('User') as $user)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;echo $row->name; // call attributes<br />
-	&nbsp;&nbsp;&nbsp;echo $row->reverse_name(); // or methods defined on the 'User' class<br />
-	}
-	</code>
-
-	<h2>result_array()</h2>
-
-	<p>This function returns the query result as a pure array, or an empty array when no result is produced.  Typically you'll use this in a foreach loop, like this:</p>
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	foreach ($query->result_array() as $row)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;echo $row['title'];<br />
-	&nbsp;&nbsp;&nbsp;echo $row['name'];<br />
-	&nbsp;&nbsp;&nbsp;echo $row['body'];<br />
-	}</code>
-
-
-	<h2>row()</h2>
-
-	<p>This function returns a single result row.  If your query has more than one row, it returns only the first row.
-	The result is returned as an <strong>object</strong>.  Here's a usage example:</p>
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	if ($query->num_rows() > 0)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;$row = $query->row();
-	<br /><br />
-	&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-	&nbsp;&nbsp;&nbsp;echo $row->name;<br />
-	&nbsp;&nbsp;&nbsp;echo $row->body;<br />
-	}
-	</code>
-
-	<p>If you want a specific row returned you can submit the row number as a digit in the first parameter:</p>
-
-	<code>$row = $query->row(<dfn>5</dfn>);</code>
-
-	<p>You can also add a second String parameter, which is the name of a class to instantiate the row with:</p>
-
-	<code>
-	$query = $this->db->query("SELECT * FROM users LIMIT 1;");<br />
-	<br />
-	$query->row(0, 'User')<br />
-	echo $row->name; // call attributes<br />
-	echo $row->reverse_name(); // or methods defined on the 'User' class<br />
-	</code>
-
-	<h2>row_array()</h2>
-
-	<p>Identical to the above <var>row()</var> function, except it returns an array.  Example:</p>
-
-	<code>
-	$query = $this->db->query("YOUR QUERY");<br />
-	<br />
-	if ($query->num_rows() > 0)<br />
-	{<br />
-	&nbsp;&nbsp;&nbsp;$row = $query->row_array();
-	<br /><br />
-	&nbsp;&nbsp;&nbsp;echo $row['title'];<br />
-	&nbsp;&nbsp;&nbsp;echo $row['name'];<br />
-	&nbsp;&nbsp;&nbsp;echo $row['body'];<br />
-	}
-	</code>
-
-
-	<p>If you want a specific row returned you can submit the row number as a digit in the first parameter:</p>
-
-	<code>$row = $query->row_array(<dfn>5</dfn>);</code>
-
-
-	<p>In addition, you can walk forward/backwards/first/last through your results using these variations:</p>
-
-<p>
-	<strong>$row = $query->first_row()</strong><br />
-	<strong>$row = $query->last_row()</strong><br />
-	<strong>$row = $query->next_row()</strong><br />
-	<strong>$row = $query->previous_row()</strong>
-</p>
-
-<p>By default they return an object unless you put the word "array" in the parameter:</p>
-
-<p>
-	<strong>$row = $query->first_row('array')</strong><br />
-	<strong>$row = $query->last_row('array')</strong><br />
-	<strong>$row = $query->next_row('array')</strong><br />
-	<strong>$row = $query->previous_row('array')</strong>
-</p>
-
-
-
-<h1>Result Helper Functions</h1>
-
-
-<h2>$query->num_rows()</h2>
-<p>The number of rows returned by the query. Note: In this example, <dfn>$query</dfn> is the variable that the query result object is assigned to:</p>
-
-<code>$query = $this->db->query('SELECT * FROM my_table');<br /><br />
-echo $query->num_rows();
-</code>
-
-<h2>$query->num_fields()</h2>
-<p>The number of FIELDS (columns) returned by the query.  Make sure to call the function using your query result object:</p>
-
-<code>$query = $this->db->query('SELECT * FROM my_table');<br /><br />
-echo $query->num_fields();
-</code>
-
-
-
-<h2>$query->free_result()</h2>
-<p>It frees the memory associated with the result and deletes the result resource ID.  Normally PHP frees its memory automatically at the end of script
-execution.  However, if you are running a lot of queries in a particular script you might want to free the result after each query result has been
-generated in order to cut down on memory consumptions.  Example:
-</p>
-
-<code>$query = $this->db->query('SELECT title FROM my_table');<br /><br />
-foreach ($query->result() as $row)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;echo $row->title;<br />
-}<br />
-$query->free_result();  // The $query result object will no longer be available<br />
-<br />
-$query2 = $this->db->query('SELECT name FROM some_table');<br /><br />
-$row = $query2->row();<br />
-echo $row->name;<br />
-$query2->free_result();  // The $query2 result object will no longer be available
-</code>

-<h1>Table Data</h1>
-
-<p>These functions let you fetch table information.</p>
-
-<h2>$this->db->list_tables();</h2>
-
-<p>Returns an array containing the names of all the tables in the database you are currently connected to.  Example:</p>
-
-<code>$tables = $this->db->list_tables();<br />
-<br />
-foreach ($tables as $table)<br />

-Returns a boolean TRUE/FALSE.  Usage example:</p>
-
-<code>
-if ($this->db->table_exists('table_name'))<br />
-{<br />
-&nbsp;&nbsp; // some code...<br />
-}

-<h1>Transactions</h1>
-
-<p>CodeIgniter's database abstraction allows you to use <dfn>transactions</dfn> with databases that support transaction-safe table types.  In MySQL, you'll need
-to be running InnoDB or BDB table types rather than the more common MyISAM.  Most other database platforms support transactions natively.</p>
-
-<p>If you are not familiar with
-transactions we recommend you find a good online resource to learn about them for your particular database.  The information below assumes you
-have a basic understanding of transactions.
-</p>
-
-<h2>CodeIgniter's Approach to Transactions</h2>
-
-<p>CodeIgniter utilizes an approach to transactions that is very similar to the process used by the popular database class ADODB.  We've chosen that approach
-because it greatly simplifies the process of running transactions.  In most cases all that is required are two lines of code.</p>
-
-<p>Traditionally, transactions have required a fair amount of work to implement since they demand that you to keep track of your queries
-and determine whether to <dfn>commit</dfn> or <dfn>rollback</dfn> based on the success or failure of your queries. This is particularly cumbersome with
-nested queries. In contrast,
-we've implemented a smart transaction system that does all this for you automatically (you can also manage your transactions manually if you choose to,
-but there's really no benefit).</p>
-
-<h2>Running Transactions</h2>
-
-<p>To run your queries using transactions you will use the <dfn>$this->db->trans_start()</dfn> and <dfn>$this->db->trans_complete()</dfn> functions as follows:</p>
-
-<code>
-<kbd>$this->db->trans_start();</kbd><br />
-$this->db->query('AN SQL QUERY...');<br />
-$this->db->query('ANOTHER QUERY...');<br />
-$this->db->query('AND YET ANOTHER QUERY...');<br />
-<kbd>$this->db->trans_complete();</kbd>
-</code>
-
-<p>You can run as many queries as you want between the start/complete functions and they will all be committed or rolled back based on success or failure
-of any given query.</p>
-
-
-<h2>Strict Mode</h2>
-
-<p>By default CodeIgniter runs all transactions in <dfn>Strict Mode</dfn>.  When strict mode is enabled, if you are running multiple groups of
-transactions, if one group fails all groups will be rolled back. If strict mode is disabled, each group is treated independently, meaning
-a failure of one group will not affect any others.</p>
-
-<p>Strict Mode can be disabled as follows:</p>
-
-<code>$this->db->trans_strict(FALSE);</code>
-
-
-<h2>Managing Errors</h2>
-
-<p>If you have error reporting enabled in your <dfn>config/database.php</dfn> file you'll see a standard error message if the commit was unsuccessful. If debugging is turned off, you can
-manage your own errors like this:</p>
-
-<code>
-$this->db->trans_start();<br />
-$this->db->query('AN SQL QUERY...');<br />
-$this->db->query('ANOTHER QUERY...');<br />
-$this->db->trans_complete();<br />
-<br />
-if (<kbd>$this->db->trans_status()</kbd> === FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;// generate an error... or use the log_message() function to log your error<br />
-}
-</code>
-
-
-<h2>Enabling Transactions</h2>
-
-<p>Transactions are enabled automatically the moment you use <dfn>$this->db->trans_start()</dfn>.  If you would like to disable transactions you
-can do so using <dfn>$this->db->trans_off()</dfn>:</p>
-
-<code>
-<kbd>$this->db->trans_off()</kbd><br /><br />
-
-$this->db->trans_start();<br />
-$this->db->query('AN SQL QUERY...');<br />
-$this->db->trans_complete();
-</code>
-
-<p class="important">When transactions are disabled, your queries will be auto-commited, just as they are when running queries without transactions.</p>
-
-
-<h2>Test Mode</h2>
-
-<p>You can optionally put the transaction system into "test mode", which will cause your queries to be rolled back -- even if the queries produce a valid result.
-To use test mode simply set the first parameter in the <dfn>$this->db->trans_start()</dfn> function to <samp>TRUE</samp>:</p>
-
-<code>
-$this->db->trans_start(<samp>TRUE</samp>); // Query will be rolled back<br />
-$this->db->query('AN SQL QUERY...');<br />
-$this->db->trans_complete();
-</code>
-
-
-<h2>Running Transactions Manually</h2>
-
-<p>If you would like to run transactions manually you can do so as follows:</p>
-
-<code>
-$this->db->trans_begin();<br /><br />
-
-$this->db->query('AN SQL QUERY...');<br />
-$this->db->query('ANOTHER QUERY...');<br />
-$this->db->query('AND YET ANOTHER QUERY...');<br />
-
-<br />
-
-if ($this->db->trans_status() === FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->db->trans_rollback();<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->db->trans_commit();<br />
-}<br />
-</code>
-
-<p class="important"><strong>Note:</strong> Make sure to use <kbd>$this->db->trans_begin()</kbd> when running manual transactions, <strong>NOT</strong>
-<dfn>$this->db->trans_start()</dfn>.</p>

-
-
-
-<h2><a name="init"></a>Initializing the Utility Class</h2>
-
-<p class="important"><strong>Important:</strong>&nbsp; In order to initialize the Utility class, your database driver must
-already be running, since the utilities class relies on it.</p>
-
-<p>Load the Utility Class as follows:</p>
-
-<code>$this->load->dbutil()</code>
-
-<p>Once initialized you will access the functions using the <dfn>$this->dbutil</dfn> object:</p>
-
-<code>$this->dbutil->some_function()</code>
-
-<h2><a name="list"></a>$this->dbutil->list_databases()</h2>
-<p>Returns an array of database names:</p>
-
-<code>
-$dbs = $this->dbutil->list_databases();<br />
-<br />
-foreach ($dbs as $db)<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo $db;<br />
-}</code>
-
-
-<h2><a name="exists"></a>$this->dbutil->database_exists();</h2>
-
-<p>Sometimes it's helpful to know whether a particular database exists.
-Returns a boolean TRUE/FALSE.  Usage example:</p>
-
-<code>
-if ($this->dbutil->database_exists('database_name'))<br />
-{<br />
-&nbsp;&nbsp; // some code...<br />
-}
-</code>
-
-<p>Note:  Replace <em>database_name</em> with the name of the table you are looking for. This function is case sensitive.</p>
-
-
-
-<h2><a name="opttb"></a>$this->dbutil->optimize_table('table_name');</h2>
-
-<p class="important"><strong>Note:</strong>&nbsp; This features is only available for MySQL/MySQLi databases.</p>
-
-
-<p>Permits you to optimize a table using the table name specified in the first parameter. Returns TRUE/FALSE based on success or failure:</p>
-
-<code>
-if ($this->dbutil->optimize_table('table_name'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo 'Success!';<br />
-}
-</code>
-
-<p><strong>Note:</strong> Not all database platforms support table optimization.</p>
-
-
-<h2><a name="repair"></a>$this->dbutil->repair_table('table_name');</h2>
-
-<p class="important"><strong>Note:</strong>&nbsp; This features is only available for MySQL/MySQLi databases.</p>
-
-
-<p>Permits you to repair a table using the table name specified in the first parameter. Returns TRUE/FALSE based on success or failure:</p>
-
-<code>
-if ($this->dbutil->repair_table('table_name'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp; echo 'Success!';<br />
-}
-</code>
-
-<p><strong>Note:</strong> Not all database platforms support table repairs.</p>
-
-
-<h2><a name="optdb"></a>$this->dbutil->optimize_database();</h2>
-
-<p class="important"><strong>Note:</strong>&nbsp; This features is only available for MySQL/MySQLi databases.</p>
-
-<p>Permits you to optimize the database your DB class is currently connected to. Returns an array containing the DB status messages or FALSE on failure.</p>
-
-<code>
-$result = $this->dbutil->optimize_database();<br />
-<br />
-if ($result !== FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp; print_r($result);<br />
-}
-</code>
-
-<p><strong>Note:</strong> Not all database platforms support table optimization.</p>
-
-
-<h2><a name="csv"></a>$this->dbutil->csv_from_result($db_result)</h2>
-
-<p>Permits you to generate a CSV file from a query result. The first parameter of the function must contain the result object from your query.
-Example:</p>
-
-<code>
-$this->load->dbutil();<br />
-<br />
-$query = $this->db->query("SELECT * FROM mytable");<br />
-<br />
-echo $this->dbutil->csv_from_result($query);
-</code>
-
-<p>The second and third parameters allows you to
-set the delimiter and newline character.  By default tabs are used as the delimiter and "\n" is used as a new line.  Example:</p>
-
-<code>
-$delimiter = ",";<br />
-$newline = "\r\n";<br />
-<br />
-echo $this->dbutil->csv_from_result($query, $delimiter, $newline);
-</code>
-
-<p><strong>Important:</strong>&nbsp; This function will NOT write the CSV file for you.  It simply creates the CSV layout.
-If you need to write the file use the <a href="../helpers/file_helper.html">File Helper</a>.</p>
-
-
-<h2><a name="xml"></a>$this->dbutil->xml_from_result($db_result)</h2>
-
-<p>Permits you to generate an XML file from a query result. The first parameter expects a query result object, the second
-may contain an optional array of config parameters.  Example:</p>
-
-<code>
-$this->load->dbutil();<br />
-<br />
-$query = $this->db->query("SELECT * FROM mytable");<br />
-<br />
-$config = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'root'&nbsp;&nbsp;&nbsp; => 'root',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'element' => 'element', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'newline' => "\n", <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tab'&nbsp;&nbsp;&nbsp;&nbsp;=> "\t"<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo $this->dbutil->xml_from_result($query, $config);
-</code>
-
-<p><strong>Important:</strong>&nbsp; This function will NOT write the XML file for you.  It simply creates the XML layout.
-If you need to write the file use the <a href="../helpers/file_helper.html">File Helper</a>.</p>
-
-
-<h2><a name="backup"></a>$this->dbutil->backup()</h2>
-
-<p>Permits you to backup your full database or individual tables.  The backup data can be compressed in either Zip or Gzip format.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; This features is only available for MySQL databases.</p>
-
-<p>Note: Due to the limited execution time and memory available to PHP, backing up very large
-databases may not be possible.  If your database is very large you might need to backup directly from your SQL server
-via the command line, or have your server admin do it for you if you do not have root privileges.</p>
-
-<h3>Usage Example</h3>
-
-<code>
-<dfn>// Load the DB utility class</dfn><br />
-$this->load->dbutil();<br /><br />
-
-<dfn>// Backup your entire database and assign it to a variable</dfn><br />
-$backup =& $this->dbutil->backup();
-
-<br /><br />
-<dfn>// Load the file helper and write the file to your server</dfn><br />
-$this->load->helper('file');<br />
-write_file('/path/to/mybackup.gz', $backup);
-
-<br /><br />
-<dfn>// Load the download helper and send the file to your desktop</dfn><br />
-$this->load->helper('download');<br />
-force_download('mybackup.gz', $backup);
-</code>
-
-<h3>Setting Backup Preferences</h3>
-
-<p>Backup preferences are set by submitting an array of values to the first parameter of the backup function. Example:</p>
-
-<code>$prefs = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tables'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> array('table1', 'table2'),&nbsp;&nbsp;// Array of tables to backup.<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ignore'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> array(),&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// List of tables to omit from the backup<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'format'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'txt',&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// gzip, zip, txt<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mybackup.sql',&nbsp;&nbsp;&nbsp;&nbsp;// File name - NEEDED ONLY WITH ZIP FILES<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'add_drop'&nbsp;&nbsp;&nbsp;&nbsp;=> TRUE,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Whether to add DROP TABLE statements to backup file<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'add_insert'&nbsp;&nbsp;=> TRUE,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Whether to add INSERT data to backup file<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'newline'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> "\n"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Newline character used in backup file<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->dbutil->backup($prefs);
-</code>
-

-<h1>Alternate PHP Syntax for View Files</h1>
-
-<p>If you do not utilize CodeIgniter's <a href="../libraries/parser.html">template engine</a>, you'll be using pure PHP
-in your View files.  To minimize the PHP code in these files, and to make it easier to identify the code blocks it is recommended that you use
-PHPs alternative syntax for control structures and short tag echo statements.  If you are not familiar with this syntax, it allows you to eliminate the braces from your code,
-and eliminate "echo" statements.</p>
-
-<h2>Automatic Short Tag Support</h2>
-
-<p><strong>Note:</strong> If you find that the syntax described in this page does not work on your server it might
-be that "short tags" are disabled in your PHP ini file. CodeIgniter will optionally rewrite short tags on-the-fly,
-allowing you to use that syntax even if your server doesn't support it.  This feature can be enabled in your
-<dfn>config/config.php</dfn> file.</p>
-
-<p class="important">Please note that if you do use this feature, if PHP errors are encountered
-in your <strong>view files</strong>, the error message and line number will not be accurately shown.  Instead, all errors
-will be shown as <kbd>eval()</kbd> errors.</p>
-
-
-<h2>Alternative Echos</h2>
-
-<p>Normally to echo, or print out a variable you would do this:</p>
-
-<code>&lt;?php echo $variable; ?></code>
-
-<p>With the alternative syntax you can instead do it this way:</p>
-
-<code>&lt;?=$variable?></code>
-
-
-
-<h2>Alternative Control Structures</h2>
-
-<p>Controls structures, like <var>if</var>, <var>for</var>, <var>foreach</var>, and <var>while</var> can be
-written in a simplified format as well.  Here is an example using foreach:</p>
-
-<code>
-&lt;ul><br />
-<br />
-<var>&lt;?php foreach ($todo as $item): ?></var><br />
-<br />
-&lt;li><var>&lt;?=$item?></var>&lt;/li><br />
-<br />
-<var>&lt;?php endforeach; ?></var><br />
-<br />
-&lt;/ul></code>
-
-<p>Notice that there are no braces.  Instead, the end brace is replaced with <var>endforeach</var>.
-Each of the control structures listed above has a similar closing syntax:
-<var>endif</var>, <var>endfor</var>, <var>endforeach</var>, and <var>endwhile</var></p>
-
-<p>Also notice that instead of using a semicolon after each structure (except the last one), there is a colon.  This is
-important!</p>
-
-<p>Here is another example, using if/elseif/else.  Notice the colons:</p>
-
-
-<code><var>&lt;?php if ($username == 'sally'): ?></var><br />
-<br />
-&nbsp;&nbsp;&nbsp;&lt;h3>Hi Sally&lt;/h3><br />
-<br />
-<var>&lt;?php elseif ($username == 'joe'): ?></var><br />
-<br />
-&nbsp;&nbsp;&nbsp;&lt;h3>Hi Joe&lt;/h3><br />
-<br />
-<var>&lt;?php else: ?></var><br />
-<br />
-&nbsp;&nbsp;&nbsp;&lt;h3>Hi unknown user&lt;/h3><br />
-<br />
-<var>&lt;?php endif; ?></var></code>

-<h1>Creating Ancillary Classes</h1>
-
-<p>In some cases you may want to develop classes that exist apart from your controllers but have the ability to
-utilize all of CodeIgniter's resources. This is easily possible as you'll see.</p>
-
-<h2>get_instance()</h2>
-
-
-<p><strong>Any class that you instantiate within your controller functions can access CodeIgniter's native resources</strong> simply by using the <kbd>get_instance()</kbd> function.
-This function returns the main CodeIgniter object.</p>
-
-<p>Normally, to call any of the available CodeIgniter functions requires you to use the <kbd>$this</kbd> construct:</p>
-
-<code>
-<strong>$this</strong>->load->helper('url');<br />
-<strong>$this</strong>->load->library('session');<br />
-<strong>$this</strong>->config->item('base_url');<br />
-etc.
-</code>
-
-<p><kbd>$this</kbd>, however, only works within your controllers, your models, or your views.
-If you would like to use CodeIgniter's classes from within your own custom classes you can do so as follows:</p>
-
-
-<p>First, assign the CodeIgniter object to a variable:</p>
-
-<code>$CI =& get_instance();</code>
-
-<p>Once you've assigned the object to a variable, you'll use that variable <em>instead</em> of <kbd>$this</kbd>:</p>
-
-<code>
-$CI =& get_instance();<br /><br />
-$CI->load->helper('url');<br />
-$CI->load->library('session');<br />
-$CI->config->item('base_url');<br />
-etc.
-</code>
-
-<p class="important"><strong>Note:</strong> You'll notice that the above get_instance() function is being passed by reference:
-<br /><br />
-<var>$CI =& get_instance();</var>
-<br /><br />
-This is very important. Assigning by reference allows you to use the original CodeIgniter object rather than creating a copy of it.</p>

-<h1>Auto-loading Resources</h1>
-
-<p>CodeIgniter comes with an "Auto-load" feature that permits libraries, helpers, and models to be initialized
-automatically every time the system runs. If you need certain resources globally throughout your application you should
-consider auto-loading them for convenience.</p>
-
-<p>The following items can be loaded automatically:</p>
-
-<ul>
-<li>Core classes found in the "libraries" folder</li>
-<li>Helper files found in the "helpers" folder</li>
-<li>Custom config files found in the "config" folder</li>
-<li>Language files found in the "system/language" folder </li>
-<li>Models found in the &quot;models&quot; folder</li>
-</ul>
-
-<p>To autoload resources, open the <var>application/config/autoload.php</var> file and add the item you want
-loaded to the <samp>autoload</samp> array. You'll find instructions in that file corresponding to each
-type of item.</p>
-
-<p class="important"><strong>Note:</strong>  Do not include the file extension (.php) when adding items to the autoload array.</p>

-<h1>Web Page Caching</h1>
-
-<p>CodeIgniter lets you cache your pages in order to achieve maximum performance.</p>
-
-<p>Although CodeIgniter is quite fast, the amount of dynamic information you display in your pages will correlate directly to the
-server resources, memory, and processing cycles utilized, which affect your page load speeds.
-By caching your pages, since they are saved in their fully rendered state, you can achieve performance that nears that of static web pages.</p>
-
-
-<h2>How Does Caching Work?</h2>
-
-<p>Caching can be enabled on a per-page basis, and you can set the length of time that a page should remain cached before being refreshed.
-When a page is loaded for the first time, the cache file will be written to your <dfn>application/cache</dfn> folder.  On subsequent page loads the cache file will be retrieved
-and sent to the requesting user's browser.  If it has expired, it will be deleted and refreshed before being sent to the browser.</p>
-
-<p>Note: The Benchmark tag is not cached so you can still view your page load speed when caching is enabled.</p>
-
-<h2>Enabling Caching</h2>
-
-<p>To enable caching, put the following tag in any of your controller functions:</p>
-
-<code>$this->output->cache(<var>n</var>);</code>
-
-<p>Where <var>n</var> is the number of <strong>minutes</strong> you wish the page to remain cached between refreshes.</p>
-
-<p>The above tag can go anywhere within a function. It is not affected by the order that it appears, so place it wherever it seems
-most logical to you. Once the tag is in place, your pages will begin being cached.</p>
-
-<p class="important"><strong>Warning:</strong> Because of the way CodeIgniter stores content for output, caching will only work if you are generating display for your controller with a <a href="./views.html">view</a>.</p>
-<p class="important"><strong>Note:</strong> Before the cache files can be written you must set the file permissions on your
-<dfn>application/cache</dfn> folder such that it is writable.</p>
-
-<h2>Deleting Caches</h2>
-
-<p>If you no longer wish to cache a file you can remove the caching tag and it will no longer be refreshed when it expires.  Note:
-Removing the tag will not delete the cache immediately.  It will have to expire normally.  If you need to remove it earlier you
-will need to manually delete it from your cache folder.</p>

-<h1>Running via the CLI</h1>
-
-<p>
-	As well as calling an applications <a href="./controllers.html">Controllers</a> via the URL in a browser they can also be loaded via the command-line interface (CLI).
-</p>
-
-
-<ul>
-<li><a href="#what">What is the CLI?</a></li>
-<li><a href="#why">Why use this method?</a></li>
-<li><a href="#how">How does it work?</a></li>
-</ul>
-
-
-<a name="what"></a>
-<h2>What is the CLI?</h2>
-
-<p><dfn>The command-line interface is a text-based method of interacting with computers.</dfn> For more information, check the <a href="http://en.wikipedia.org/wiki/Command-line_interface">Wikipedia article</a>.</p>
-
-<a name="why"></a>
-
-<h2>Why run via the command-line?</h2>
-
-<p>
-	There are many reasons for running CodeIgniter from the command-line, but they are not always obvious.</p>
-
-<ul>
-	<li>Run your cron-jobs without needing to use wget or curl</li>
-	<li>Make your cron-jobs inaccessible from being loaded in the URL by checking for <kbd>IS_CLI</kbd></li>
-	<li>Make interactive "tasks" that can do things like set permissions, prune cache folders, run backups, etc.</li>
-	<li>Integrate with other applications in other languages. For example, a random C++ script could call one command and run code in your models!</li>
-</ul>
-
-<a name="how"></a>
-<h2>Let's try it:&nbsp; Hello World!</h2>
-
-<p>Let's create a simple controller so you can see it in action. Using your text editor, create a file called <dfn>tools.php</dfn>, and put the following code in it:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;?php
-class Tools extends CI_Controller {
-
-	public function message($to = 'World')
-	{
-		echo "Hello {$to}!".PHP_EOL;
-	}
-}
-?&gt;
-</textarea>
-
-<p>Then save the file to your <dfn>application/controllers/</dfn> folder.</p>
-
-<p>Now normally you would visit the your site using a URL similar to this:</p>
-
-<code>example.com/index.php/<var>tools</var>/<var>message</var>/<var>to</var></code>
-
-<p>Instead, we are going to open Terminal in Mac/Lunix or go to Run > "cmd" in Windows and navigate to our CodeIgniter project.</p>
-
-<blockquote>
-	$ cd /path/to/project;<br/>
-	$ php index.php tools message
-</blockquote>
-
-<p>If you did it right, you should see <samp>Hello World!</samp>.</p>
-
-<blockquote>
-	$ php index.php tools message "John Smith"
-</blockquote>
-
-<p>Here we are passing it a argument in the same way that URL parameters work. "John Smith" is passed as a argument and output is: <samp>Hello John Smith!</samp>.</p>
-
-<h2>That's it!</h2>
-
-<p>That, in a nutshell, is all there is to know about controllers on the command line. Remember that this is just a normal controller, so routing and _remap works fine.</p>

-<h1>Common Functions</h1>
-
-<p>CodeIgniter uses a few functions for its operation that are globally defined, and are available to you at any point. These do not require loading any libraries or helpers.</p>
-
-<h2>is_php('<var>version_number</var>')</h2>
-
-<p>is_php() determines of the PHP version being used is greater than the supplied <var>version_number</var>.</p>
-
-<code>if (is_php('5.3.0'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$str = quoted_printable_encode($str);<br />
-}</code>
-
-<p>Returns boolean <kbd>TRUE</kbd> if the installed version of PHP is equal to or greater than the supplied version number.  Returns  <kbd>FALSE</kbd> if the installed version of PHP is lower than the supplied version number.</p>
-
-
-<h2>is_really_writable('<var>path/to/file</var>')</h2>
-
-<p>is_writable() returns TRUE on Windows servers when you really can't write to the file as the OS reports to PHP as FALSE only if the read-only attribute is marked. This function determines if a file is actually writable by attempting to write to it first. Generally only recommended on platforms where this information may be unreliable.</p>
-
-<code>if (is_really_writable('file.txt'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo &quot;I could write to this if I wanted to&quot;;<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo &quot;File is not writable&quot;;<br />
-}</code>
-
-<h2>config_item('<var>item_key</var>')</h2>
-<p>The <a href="../libraries/config.html">Config library</a> is the preferred way of accessing configuration information, however config_item() can be used to retrieve single keys. See Config library documentation for more information.</p>
-
-<h2>show_error('<var>message</var>'), show_404('<var>page</var>'), log_message('<var>level</var>', '<samp>message</samp>')</h2>
-<p>These are each outlined on the <a href="errors.html">Error Handling</a> page.</p>
-
-<h2>set_status_header(<var>code</var>, '<var>text</var>');</h2>
-
-<p>Permits you to manually set a server status header.  Example:</p>
-
-<code>set_status_header(401);<br />
-// Sets the header as:  Unauthorized</code>
-
-<p><a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html">See here</a> for a full list of headers.</p>
-
-
-<h2>remove_invisible_characters(<var>$str</var>)</h2>
-<p>This function prevents inserting null characters between ascii characters, like Java\0script.</p>

-<h2>What is a Controller?</h2>
-
-<p><dfn>A Controller is simply a class file that is named in a way that can be associated with a URI.</dfn></p>
-
-<p>Consider this URI:</p>
-
-<code>example.com/index.php/<var>blog</var>/</code>
-
-<p>In the above example, CodeIgniter would attempt to find a controller named <dfn>blog.php</dfn> and load it.</p>
-
-<p><strong>When a controller's name matches the first segment of a URI, it will be loaded.</strong></p>
-
-<a name="hello"></a>
-<h2>Let's try it:&nbsp; Hello World!</h2>
-
-<p>Let's create a simple controller so you can see it in action.  Using your text editor, create a file called <dfn>blog.php</dfn>, and put the following code in it:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;?php
-class Blog extends CI_Controller {
-
-	public function index()
-	{
-		echo 'Hello World!';
-	}
-}
-?&gt;
-</textarea>
-
-
-
-<p>Then save the file to your <dfn>application/controllers/</dfn> folder.</p>
-
-<p>Now visit the your site using a URL similar to this:</p>
-
-<code>example.com/index.php/<var>blog</var>/</code>
-
-<p>If you did it right, you should see <samp>Hello World!</samp>.</p>
-
-<p>Note: Class names must start with an uppercase letter.  In other words, this is valid:</p>
-
-<code>&lt;?php<br />
-class <var>Blog</var> extends CI_Controller {<br />
-<br />
-}<br />
-?&gt;</code>
-
-<p>This is <strong>not</strong> valid:</p>
-
-<code>&lt;?php<br />
-class <var>blog</var> extends CI_Controller {<br />
-<br />
-}<br />
-?&gt;</code>
-
-<p>Also, always make sure your controller <dfn>extends</dfn> the parent controller class so that it can inherit all its functions.</p>
-
-
-
-<a name="functions"></a>
-<h2>Functions</h2>
-
-<p>In the above example the function name is <dfn>index()</dfn>.  The "index" function is always loaded by default if the
-<strong>second segment</strong> of the URI is empty.  Another way to show your "Hello World" message would be this:</p>
-
-<code>example.com/index.php/<var>blog</var>/<samp>index</samp>/</code>
-
-<p><strong>The second segment of the URI determines which function in the controller gets called.</strong></p>
-
-<p>Let's try it.  Add a new function to your controller:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="15">
-&lt;?php
-class Blog extends CI_Controller {
-
-	public function index()
-	{
-		echo 'Hello World!';
-	}
-
-	public function comments()
-	{
-		echo 'Look at this!';
-	}
-}
-?&gt;
-</textarea>
-
-<p>Now load the following URL to see the <dfn>comment</dfn> function:</p>
-
-<code>example.com/index.php/<var>blog</var>/<samp>comments</samp>/</code>
-
-<p>You should see your new message.</p>
-
-<a name="passinguri"></a>
-<h2>Passing URI Segments to your Functions</h2>
-
-<p>If your URI contains more then two segments they will be passed to your function as parameters.</p>
-
-<p>For example, lets say you have a URI like this:</p>
-
-<code>example.com/index.php/<var>products</var>/<samp>shoes</samp>/<kbd>sandals</kbd>/<dfn>123</dfn></code>
-
-<p>Your function will be passed URI segments 3 and 4 ("sandals" and "123"):</p>
-
-<code>
-&lt;?php<br />
-class Products extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;public function shoes($sandals, $id)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $sandals;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $id;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}<br />
-?&gt;
-</code>
-
-<p class="important"><strong>Important:</strong>&nbsp; If you are using the <a href="routing.html">URI Routing</a> feature, the segments
-passed to your function will be the re-routed ones.</p>
-
-
-<a name="default"></a>
-<h2>Defining a Default Controller</h2>
-
-<p>CodeIgniter can be told to load a default controller when a URI is not present,
-as will be the case when only your site root URL is requested.  To specify a default controller, open
-your <dfn>application/config/routes.php</dfn> file and set this variable:</p>
-
-<code>$route['default_controller'] = '<var>Blog</var>';</code>
-
-<p>Where <var>Blog</var> is the name of the controller class you want used. If you now load your main index.php file without
-specifying any URI segments you'll see your Hello World message by default.</p>
-
-
-
-<a name="remapping"></a>
-<h2>Remapping Function Calls</h2>
-
-<p>As noted above, the second segment of the URI typically determines which function in the controller gets called.
-CodeIgniter permits you to override this behavior through the use of the <kbd>_remap()</kbd> function:</p>
-
-<code>public function _remap()<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;// Some code here...<br />
-}</code>
-
-<p class="important"><strong>Important:</strong>&nbsp; If your controller contains a function named <kbd>_remap()</kbd>, it will <strong>always</strong>
-get called regardless of what your URI contains.  It overrides the normal behavior in which the URI determines which function is called,
-allowing you to define your own function routing rules.</p>
-
-<p>The overridden function call (typically the second segment of the URI) will be passed as a parameter to the <kbd>_remap()</kbd> function:</p>
-
-<code>public function _remap(<var>$method</var>)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;if ($method == 'some_method')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->$method();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;else<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->default_method();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<p>Any extra segments after the method name are passed into <kbd>_remap()</kbd> as an optional second parameter. This array can be used in combination with PHP's <a href="http://php.net/call_user_func_array">call_user_func_array</a> to emulate CodeIgniter's default behavior.</p>
-
-<code>public function _remap($method, $params = array())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$method = 'process_'.$method;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;if (method_exists($this, $method))<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return call_user_func_array(array($this, $method), $params);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;show_404();<br />
-}</code>
-
-
-<a name="output"></a>
-<h2>Processing Output</h2>
-
-<p>CodeIgniter has an output class that takes care of sending your final rendered data to the web browser automatically.  More information on this can be found in the
-<a href="views.html">Views</a> and <a href="../libraries/output.html">Output class</a> pages.  In some cases, however, you might want to
-post-process the finalized data in some way and send it to the browser yourself.  CodeIgniter permits you to
-add a function named <dfn>_output()</dfn> to your controller that will receive the finalized output data.</p>
-
-<p><strong>Important:</strong>&nbsp; If your controller contains a function named <kbd>_output()</kbd>, it will <strong>always</strong>
-be called by the output class instead of echoing the finalized data directly. The first parameter of the function will contain the finalized output.</p>
-
-<p>Here is an example:</p>
-
-<code>
-public function _output($output)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $output;<br />
-}</code>
-
-<p class="important">Please note that your <dfn>_output()</dfn> function will receive the data in its finalized state.  Benchmark and memory usage data will be rendered,
-cache files written (if you have caching enabled), and headers will be sent (if you use that <a href="../libraries/output.html">feature</a>)
-before it is handed off to the _output() function.<br />
-<br />
-To have your controller's output cached properly, its <dfn>_output()</dfn> method can use:<br />
-
-<code>if ($this-&gt;output-&gt;cache_expiration &gt; 0)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;output-&gt;_write_cache($output);<br />
-}</code>
-
-If you are using this feature the page execution timer and memory usage stats might not be perfectly accurate
-since they will not take into acccount any further processing you do.  For an alternate way to control output <em>before</em> any of the final processing is done, please see
-the available methods in the <a href="../libraries/output.html">Output Class</a>.</p>
-
-<a name="private"></a>
-<h2>Private Functions</h2>
-
-
-<p>In some cases you may want certain functions hidden from public access.  To make a function private, simply add an
-underscore as the name prefix and it will not be served via a URL request. For example, if you were to have a function like this:</p>
-
-<code>
-private function _utility()<br />
-{<br />
-&nbsp;&nbsp;// some code<br />
-}</code>
-
-<p>Trying to access it via the URL, like this, will not work:</p>
-
-<code>example.com/index.php/<var>blog</var>/<samp>_utility</samp>/</code>
-
-
-
-<a name="subfolders"></a>
-<h2>Organizing Your Controllers into Sub-folders</h2>
-
-<p>If you are building a large application you might find it convenient to organize your controllers into sub-folders.  CodeIgniter permits you to do this.</p>
-
-<p>Simply create folders within your <dfn>application/controllers</dfn> directory and place your controller classes within them.</p>
-
-<p><strong>Note:</strong>&nbsp; When using this feature the first segment of your URI must specify the folder.  For example, lets say you have a controller
-located here:</p>
-
-<code>application/controllers/<kbd>products</kbd>/shoes.php</code>
-
-<p>To call the above controller your URI will look something like this:</p>
-
-<code>example.com/index.php/products/shoes/show/123</code>
-
-<p>Each of your sub-folders may contain a default controller which will be
-called if the URL contains only the sub-folder.  Simply name your default controller as specified in your
-<dfn>application/config/routes.php</dfn> file</p>
-
-
-<p>CodeIgniter also permits you to remap your URIs using its <a href="routing.html">URI Routing</a> feature.</p>
-
-
-<h2><a name="constructors"></a>Class Constructors</h2>
-
-
-<p>If you intend to use a constructor in any of your Controllers, you <strong>MUST</strong> place the following line of code in it:</p>
-
-<code>parent::__construct();</code>
-
-<p>The reason this line is necessary is because your local constructor will be overriding the one in the parent controller class so we need to manually call it.</p>
-
-<code>
-&lt;?php<br />
-class <kbd>Blog</kbd> extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;public function <kbd>__construct()</kbd><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<var>parent::__construct();</var><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Your own constructor code<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}<br />
-?&gt;</code>
-
-<p>Constructors are useful if you need to set some default values, or run a default process when your class is instantiated.
-Constructors can't return a value, but they can do some default work.</p>
-
-<a name="reserved"></a>
-<h2>Reserved Function Names</h2>
-
-<p>Since your controller classes will extend the main application controller you
-must be careful not to name your functions identically to the ones used by that class, otherwise your local functions
-will override them. See <a href="reserved_names.html">Reserved Names</a> for a full list.</p>
-
-<h2>That's it!</h2>
-
-<p>That, in a nutshell, is all there is to know about controllers.</p>

-<h1>Creating Core System Classes</h1>
-
-<p>Every time CodeIgniter runs there are several base classes that are initialized automatically as part of the core framework.
-It is possible, however, to swap any of the core system classes with your own versions or even extend the core versions.</p>
-
-<p><strong>Most users will never have any need to do this,
-but the option to replace or extend them does exist for those who would like to significantly alter the CodeIgniter core.</strong>
-</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; Messing with a core system class has a lot of implications, so make sure you
-know what you are doing before attempting it.</p>
-
-
-<h2>System Class List</h2>
-
-<p>The following is a list of the core system files that are invoked every time CodeIgniter runs:</p>
-
-<ul>
-<li>Benchmark</li>
-<li>Config</li>
-<li>Controller</li>
-<li>Exceptions</li>
-<li>Hooks</li>
-<li>Input</li>
-<li>Language</li>
-<li>Loader</li>
-<li>Log</li>
-<li>Output</li>
-<li>Router</li>
-<li>URI</li>
-<li>Utf8</li>
-</ul>
-
-<h2>Replacing Core Classes</h2>
-
-<p>To use one of your own system classes instead of a default one simply place your version inside your local <dfn>application/core</dfn> directory:</p>
-
-<code>application/core/<dfn>some-class.php</dfn></code>
-
-<p>If this directory does not exist you can create it.</p>
-
-<p>Any file named identically to one from the list above will be used instead of the one normally used.</p>
-
-<p>Please note that your class must use <kbd>CI</kbd> as a prefix. For example, if your file is named <kbd>Input.php</kbd> the class will be named:</p>
-
-<code>
-class CI_Input {<br /><br />
-
-}
-</code>
-
-
-
-<h2>Extending Core Class</h2>
-
-<p>If all you need to do is add some functionality to an existing library - perhaps add a function or two - then
-it's overkill to replace the entire library with your version.  In this case it's better to simply extend the class.
-Extending a class is nearly identical to replacing a class with a couple exceptions:</p>
-
-<ul>
-<li>The class declaration must extend the parent class.</li>
-<li>Your new class name and filename must be prefixed with <kbd>MY_</kbd> (this item is configurable.  See below.).</li>
-</ul>
-
-<p>For example, to extend the native <kbd>Input</kbd> class you'll create a file named <dfn>application/core/</dfn><kbd>MY_Input.php</kbd>, and declare your class with:</p>
-
-<code>
-class MY_Input extends CI_Input {<br /><br />
-
-}</code>
-
-<p>Note: If you need to use a constructor in your class make sure you extend the parent constructor:</p>
-
-<code>
-class MY_Input extends CI_Input {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function __construct()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<p class="important"><strong>Tip:</strong>&nbsp; Any functions in your class that are named identically to the functions in the parent class will be used instead of the native ones
-(this is known as "method overriding").
-This allows you to substantially alter the CodeIgniter core.</p>
-
-<p>If you are extending the Controller core class, then be sure to extend your new class in your application controller's constructors.</p>
-
-<code>class Welcome extends MY_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function __construct()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function index()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('welcome_message');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<h3>Setting Your Own Prefix</h3>
-
-<p>To set your own sub-class prefix, open your <dfn>application/config/config.php</dfn> file and look for this item:</p>
-
-<code>$config['subclass_prefix'] = 'MY_';</code>
-
-<p>Please note that all native CodeIgniter libraries are prefixed with <kbd>CI_</kbd> so DO NOT use that as your prefix.</p>

-<h1>Creating Libraries</h1>
-
-<p>When we use the term "Libraries" we are normally referring to the classes that are located in the <kbd>libraries</kbd>
-directory and described in the Class Reference of this user guide.  In this case, however, we will instead describe how you can create
-your own libraries within your <dfn>application/libraries</dfn> directory in order to maintain separation between your local resources
-and the global framework resources.</p>
-
-<p>As an added bonus, CodeIgniter permits your libraries to <kbd>extend</kbd> native classes if you simply need to add some functionality
-to an existing library. Or you can even replace native libraries just by placing identically named versions in your <dfn>application/libraries</dfn> folder.</p>
-
-<p>In summary:</p>
-
-<ul>
-<li>You can create entirely new libraries.</li>
-<li>You can extend native libraries.</li>
-<li>You can replace native libraries.</li>
-</ul>
-
-<p>The page below explains these three concepts in detail.</p>
-
-<p class="important"><strong>Note:</strong> The Database classes can not be extended or replaced with your own classes.  All other classes are able to be replaced/extended.</p>
-
-
-<h2>Storage</h2>
-
-<p>Your library classes should be placed within your <dfn>application/libraries</dfn> folder, as this is where CodeIgniter will look for them when
-they are initialized.</p>
-
-
-<h2>Naming Conventions</h2>
-
-<ul>
-<li>File names must be capitalized. For example:&nbsp; <dfn>Myclass.php</dfn></li>
-<li>Class declarations must be capitalized. For example:&nbsp;  <kbd>class Myclass</kbd></li>
-<li>Class names and file names must match.</li>
-</ul>
-
-
-<h2>The Class File</h2>
-
-<p>Classes should have this basic prototype (Note:  We are using the name <kbd>Someclass</kbd> purely as an example):</p>
-
-<code>&lt;?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
-<br /><br />
-class Someclass {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;public function some_function()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}<br /><br />
-/* End of file Someclass.php */</code>
-
-
-<h2>Using Your Class</h2>
-
-<p>From within any of your <a href="controllers.html">Controller</a> functions you can initialize your class using the standard:</p>
-
-<code>$this->load->library('<kbd>someclass</kbd>');</code>
-
-<p>Where <em>someclass</em> is the file name, without the ".php" file extension. You can submit the file name capitalized or lower case.
-CodeIgniter doesn't care.</p>
-
-<p>Once loaded you can access your class using the <kbd>lower case</kbd> version:</p>
-
-<code>$this-><kbd>someclass</kbd>->some_function();&nbsp; // Object instances will always be lower case
-</code>
-
-
-
-<h2>Passing Parameters When Initializing Your Class</h2>
-
-<p>In the library loading function you can dynamically pass data as an array via the second parameter and it will be passed to your class
-constructor:</p>
-
-<code>
-$params = array('type' => 'large', 'color' => 'red');<br />
-<br />
-$this->load->library('Someclass', <kbd>$params</kbd>);</code>
-
-<p>If you use this feature you must set up your class constructor to expect data:</p>
-
-<code>&lt;?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');<br />
-<br />
-class Someclass {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;public function __construct($params)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Do something with $params<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}<br /><br />
-?&gt;</code>
-
-<p class="important">You can also pass parameters stored in a config file.  Simply create a config file named identically to the class <kbd>file name</kbd>
-and store it in your <dfn>application/config/</dfn> folder.  Note that if you dynamically pass parameters as described above,
-the config file option will not be available.</p>
-
-
-
-
-
-
-
-<h2>Utilizing CodeIgniter Resources within Your Library</h2>
-
-
-<p>To access CodeIgniter's native resources within your library use the <kbd>get_instance()</kbd> function.
-This function returns the CodeIgniter super object.</p>
-
-<p>Normally from within your controller functions you will call any of the available CodeIgniter functions using the <kbd>$this</kbd> construct:</p>
-
-<code>
-<strong>$this</strong>->load->helper('url');<br />
-<strong>$this</strong>->load->library('session');<br />
-<strong>$this</strong>->config->item('base_url');<br />
-etc.
-</code>
-
-<p><kbd>$this</kbd>, however, only works directly within your controllers, your models, or your views.
-If you would like to use CodeIgniter's classes from within your own custom classes you can do so as follows:</p>
-
-
-<p>First, assign the CodeIgniter object to a variable:</p>
-
-<code>$CI =&amp; get_instance();</code>
-
-<p>Once you've assigned the object to a variable, you'll use that variable <em>instead</em> of <kbd>$this</kbd>:</p>
-
-<code>
-$CI =&amp; get_instance();<br />
-<br />
-$CI->load->helper('url');<br />
-$CI->load->library('session');<br />
-$CI->config->item('base_url');<br />
-etc.
-</code>
-
-<p class="important"><strong>Note:</strong> You'll notice that the above get_instance() function is being passed by reference:
-<br /><br />
-<var>$CI =&amp; get_instance();</var>
-<br />
-<br />
-<kbd>This is very important.</kbd> Assigning by reference allows you to use the original CodeIgniter object rather than creating a copy of it.</p>
-
-
-<h2>Replacing Native Libraries with Your Versions</h2>
-
-<p>Simply by naming your class files identically to a native library will cause CodeIgniter to use it instead of the native one. To use this
-feature you must name the file and the class declaration exactly the same as the native library.  For example, to replace the native <kbd>Email</kbd> library
-you'll create a file named <dfn>application/libraries/Email.php</dfn>, and declare your class with:</p>
-
-<code>
-class CI_Email {<br /><br />
-
-}</code>
-
-<p>Note that most native classes are prefixed with <kbd>CI_</kbd>.</p>
-
-<p>To load your library you'll see the standard loading function:</p>
-
-<code>$this->load->library('<kbd>email</kbd>');</code>
-
-<p class="important"><strong>Note:</strong> At this time the Database classes can not be replaced with your own versions.</p>
-
-
-<h2>Extending Native Libraries</h2>
-
-<p>If all you need to do is add some functionality to an existing library - perhaps add a function or two - then
-it's overkill to replace the entire library with your version.  In this case it's better to simply extend the class.
-Extending a class is nearly identical to replacing a class with a couple exceptions:</p>
-
-<ul>
-<li>The class declaration must extend the parent class.</li>
-<li>Your new class name and filename must be prefixed with <kbd>MY_</kbd> (this item is configurable.  See below.).</li>
-</ul>
-
-<p>For example, to extend the native <kbd>Email</kbd> class you'll create a file named <dfn>application/libraries/</dfn><kbd>MY_Email.php</kbd>, and declare your class with:</p>
-
-<code>
-class MY_Email extends CI_Email {<br /><br />
-
-}</code>
-
-<p>Note: If you need to use a constructor in your class make sure you extend the parent constructor:</p>
-
-
-<code>
-class MY_Email extends CI_Email {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;public function __construct()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-
-<h3>Loading Your Sub-class</h3>
-
-<p>To load your sub-class you'll use the standard syntax normally used.  DO NOT include your prefix.  For example,
-to load the example above, which extends the Email class, you will use:</p>
-
-<code>$this->load->library('<kbd>email</kbd>');</code>
-
-<p>Once loaded you will use the class variable as you normally would for the class you are extending.  In the case of
-the email class all calls will use:</p>
-
-
-<code>$this-><kbd>email</kbd>->some_function();</code>
-
-
-<h3>Setting Your Own Prefix</h3>
-
-<p>To set your own sub-class prefix, open your <dfn>application/config/config.php</dfn> file and look for this item:</p>
-
-<code>$config['subclass_prefix'] = 'MY_';</code>
-
-<p>Please note that all native CodeIgniter libraries are prefixed with <kbd>CI_</kbd> so DO NOT use that as your prefix.</p>

-<h1>Credits</h1>
-
-<p>CodeIgniter was originally developed by <a href="http://www.ellislab.com/">Rick Ellis</a> (CEO of
-<a href="http://ellislab.com/">EllisLab, Inc.</a>).  The framework was written for performance in the real
-world, with many of the class libraries, helpers, and sub-systems borrowed from the code-base of
-<a href="http://www.expressionengine.com/">ExpressionEngine</a>.</p>
-
-<p>It is currently developed and maintained by the ExpressionEngine Development Team.<br />
-Bleeding edge development is spearheaded by the handpicked contributors of the Reactor Team.</p>
-
-<p>A hat tip goes to Ruby on Rails for inspiring us to create a PHP framework, and for
-bringing frameworks into the general consciousness of the web community.</p>

-<h1>Using CodeIgniter Drivers</h1>
-
-
-<p>Drivers are a special type of Library that has a parent class and any number of potential child classes.  Child classes have access to the parent class, but not their siblings.  Drivers provide an elegant syntax  in your <a href="controllers.html">controllers</a> for libraries that benefit from or require being broken down into discrete classes.</p>
-
-<p>Drivers are found in the <dfn>system/libraries</dfn> folder, in their own folder which is identically named to the parent library class.  Also inside that folder is a subfolder named <kbd>drivers</kbd>, which contains all of the possible child class files.</p>
-
-<p>To use a driver you will initialize it within a controller using the following initialization function:</p>
-
-<code>$this->load->driver('<var>class name</var>'); </code>
-
-<p>Where <var>class name</var> is the name of the driver class you want to invoke.  For example, to load a driver named "Some Parent" you would do this:</p>
-
-<code>$this->load->driver('<var>some_parent</var>');</code>
-
-<p>Methods of that class can then be invoked with:</p>
-
-<code>$this->some_parent->some_method();</code>
-
-<p>The child classes, the drivers themselves, can then be called directly through the parent class, without initializing them:</p>
-
-<code>$this->some_parent->child_one->some_method();<br />
-$this->some_parent->child_two->another_method();</code>
-

-<h1>Handling Multiple Environments</h1>
-
-<p>
-    Developers often desire different system behavior depending on whether
-    an application is running in a development or production
-    environment. For example, verbose error output is something that would
-    be useful while developing an application, but it may also pose a security issue when "live".
-</p>
-
-<h2>The ENVIRONMENT Constant</h2>
-
-<p>
-    By default, CodeIgniter comes with the environment constant set to
-    '<kbd>development</kbd>'. At the top of index.php, you will see:
-</p>
-
-<code>
-define('<var>ENVIRONMENT</var>', '<var>development</var>');
-</code>
-
-<p>
-    In addition to affecting some basic framework behavior (see the next section),
-    you may use this constant in your own development to differentiate
-    between which environment you are running in.
-</p>
-
-<h2>Effects On Default Framework Behavior</h2>
-
-<p>
-    There are some places in the CodeIgniter system where the <kbd>ENVIRONMENT</kbd>
-    constant is used. This section describes how default framework behavior is
-    affected.
-</p>
-
-<h3>Error Reporting</h3>
-
-<p>
-    Setting the <kbd>ENVIRONMENT</kbd> constant to a value of '<kbd>development</kbd>' will
-    cause all PHP errors to be rendered to the browser when they occur. Conversely,
-    setting the constant to '<kbd>production</kbd>' will disable all error output. Disabling
-    error reporting in production is a <a href="security.html">good security practice</a>.
-</p>
-
-<h3>Configuration Files</h3>
-
-<p>
-    Optionally, you can have CodeIgniter load environment-specific
-    configuration files. This may be useful for managing things like differing API keys
-    across multiple environments. This is described in more detail in the
-    environment section of the <a href="../libraries/config.html#environments">Config Class</a> documentation.

-<h1>Error Handling</h1>
-
-<p>CodeIgniter lets you build error reporting into your applications using the functions described below.
-In addition, it has an error logging class that permits error and debugging messages to be saved as text files.</p>
-
-<p class="important"><strong>Note:</strong> By default, CodeIgniter displays all PHP errors.  You might
-wish to change this behavior once your development is complete.  You'll find the <dfn>error_reporting()</dfn>
-function located at the top of your main index.php file. Disabling error reporting will NOT prevent log files
-from being written if there are errors.</p>
-
-<p>Unlike most systems in CodeIgniter, the error functions are simple procedural interfaces that are available
-globally throughout the application.  This approach permits error messages to get triggered without having to worry
-about class/function scoping.</p>
-
-<p>The following functions let you generate errors:</p>
-
-<h2>show_error('<var>message</var>' [, int <var>$status_code</var>= 500 ] )</h2>
-<p>This function will display the error message supplied to it using the following error template:</p>
-<p><dfn>application/errors/</dfn><kbd>error_general.php</kbd></p>
-<p>The optional parameter $status_code determines what HTTP status code should be sent with the error.</p>
-
-<h2>show_404('<var>page</var>' [, '<var>log_error</var>'])</h2>
-<p>This function will display the 404 error message supplied to it using the following error template:</p>
-<p><dfn>application/errors/</dfn><kbd>error_404.php</kbd></p>
-
-<p>The function expects the string passed to it to be the file path to the page that isn't found.
-Note that CodeIgniter automatically shows 404 messages if controllers are not found.</p>
-
-<p>CodeIgniter automatically logs any show_404() calls. Setting the optional second parameter to FALSE will skip logging.</p>
-
-
-<h2>log_message('<var>level</var>', '<samp>message</samp>')</h2>
-
-<p>This function lets you write messages to your log files.  You must supply one of three "levels"
-in the first parameter, indicating what type of message it is (debug, error, info), with the message
-itself in the second parameter.  Example:</p>
-
-<code>
-if ($some_var == "")<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;log_message('error', 'Some variable did not contain a value.');<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;log_message('debug', 'Some variable was correctly set');<br />
-}<br />
-<br />
-log_message('info', 'The purpose of some variable is to provide some value.');<br />
-</code>
-
-<p>There are three message types:</p>
-
-<ol>
-<li>Error Messages.  These are actual errors, such as PHP errors or user errors.</li>
-<li>Debug Messages.  These are messages that assist in debugging. For example, if a class has been initialized, you could log this as debugging info.</li>
-<li>Informational Messages.  These are the lowest priority messages, simply giving information regarding some process.  CodeIgniter doesn't natively generate any info messages but you may want to in your application.</li>
-</ol>
-
-
-<p class="important"><strong>Note:</strong> In order for the log file to actually be written, the
- "logs" folder must be writable.  In addition, you must set the "threshold" for logging in <dfn>application/config/config.php</dfn>.
-You might, for example, only want error messages to be logged, and not the other two types.
-If you set it to zero logging will be disabled.</p>

-<h1>Helper Functions</h1>
-
-<p>Helpers, as the name suggests, help you with tasks.  Each helper file is simply a collection of functions in a particular
-category.  There are <dfn>URL Helpers</dfn>, that assist in creating links, there are <dfn>Form Helpers</dfn>
-that help you create form elements, <dfn>Text Helpers</dfn> perform various text formatting routines,
-<dfn>Cookie Helpers</dfn> set and read cookies, <dfn>File Helpers</dfn> help you deal with files, etc.
-</p>
-
-<p>Unlike most other systems in CodeIgniter, Helpers are not written in an Object Oriented format.  They are simple, procedural functions.
-Each helper function performs one specific task, with no dependence on other functions.</p>
-
-<p>CodeIgniter does not load Helper Files by default, so the first step in using
-a Helper is to load it.  Once loaded, it becomes globally available in your <a href="../general/controllers.html">controller</a> and <a href="../general/views.html">views</a>.</p>
-
-<p>Helpers are typically stored in your <dfn>system/helpers</dfn>, or <dfn>application/helpers </dfn>directory.	CodeIgniter will look first in your <dfn>application/helpers</dfn>
-directory.  If the directory does not exist or the specified helper is not located there CI will instead look in your global
-<dfn>system/helpers</dfn> folder.</p>
-
-
-<h2>Loading a Helper</h2>
-
-<p>Loading a helper file is quite simple using the following function:</p>
-
-<code>$this->load->helper('<var>name</var>');</code>
-
-<p>Where <var>name</var> is the file name of the helper, without the .php file extension or the "helper" part.</p>
-
-<p>For example, to load the <dfn>URL Helper</dfn> file, which is named <var>url_helper.php</var>, you would do this:</p>
-
-<code>$this->load->helper('<var>url</var>');</code>
-
-<p>A helper can be loaded anywhere within your controller functions (or even within your View files, although that's not a good practice),
-as long as you load it before you use it.  You can load your helpers in your controller constructor so that they become available
-automatically in any function, or you can load a helper in a specific function that needs it.</p>
-
-<p class="important">Note: The Helper loading function above does not return a value, so don't try to assign it to a variable.  Just use it as shown.</p>
-
-
-<h2>Loading Multiple Helpers</h2>
-
-<p>If you need to load more than one helper you can specify them in an array, like this:</p>
-
-<code>$this->load->helper( <samp>array(</samp>'<var>helper1</var>', '<var>helper2</var>', '<var>helper3</var>'<samp>)</samp> );</code>
-
-<h2>Auto-loading Helpers</h2>
-
-<p>If you find that you need a particular helper globally throughout your application, you can tell CodeIgniter to auto-load it during system initialization.
-This is done by opening the <var>application/config/autoload.php</var> file and adding the helper to the autoload array.</p>
-
-
-<h2>Using a Helper</h2>
-
-<p>Once you've loaded the Helper File containing the function you intend to use, you'll call it the way you would a standard PHP function.</p>
-
-<p>For example, to create a link using the <dfn>anchor()</dfn> function in one of your view files you would do this:</p>
-
-<code>&lt;?php echo anchor('blog/comments', 'Click Here');?&gt;</code>
-
-<p>Where "Click Here" is the name of the link, and "blog/comments" is the URI to the controller/function you wish to link to.</p>
-
-<h2>"Extending" Helpers</h2>
-
-<p>To "extend" Helpers, create a file in your <dfn>application/helpers/</dfn> folder with an identical name to the existing Helper, but prefixed with <kbd>MY_</kbd> (this item is configurable.  See below.).</p>
-
-<p>If all you need to do is add some functionality to an existing helper - perhaps add a function or two, or change how a particular
-	helper function operates - then it's overkill to replace the entire helper with your version.  In this case it's better to simply
-	"extend" the Helper.  The term "extend" is used loosely since Helper functions are procedural and discrete and cannot be extended
-	in the traditional programmatic sense.  Under the hood, this gives you the ability to add to the functions a Helper provides,
-	or to modify how the native Helper functions operate.</p>
-
-<p>For example, to extend the native <kbd>Array Helper</kbd> you'll create a file named <dfn>application/helpers/</dfn><kbd>MY_array_helper.php</kbd>, and add or override functions:</p>
-
-<code>
-// any_in_array() is not in the Array Helper, so it defines a new function<br />
-function any_in_array($needle, $haystack)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$needle = (is_array($needle)) ? $needle : array($needle);<br />
-	<br />
-&nbsp;&nbsp;&nbsp;&nbsp;foreach ($needle as $item)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (in_array($item, $haystack))<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return TRUE;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-	<br />
-&nbsp;&nbsp;&nbsp;&nbsp;return FALSE;<br />
-}<br />
-<br />
-// random_element() is included in Array Helper, so it overrides the native function<br />
-function random_element($array)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;shuffle($array);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;return array_pop($array);<br />
-}<br />
-</code>
-
-<h3>Setting Your Own Prefix</h3>
-
-<p>The filename prefix for "extending" Helpers is the same used to extend libraries and Core classes.  To set your own prefix, open your <dfn>application/config/config.php</dfn> file and look for this item:</p>
-
-<code>$config['subclass_prefix'] = 'MY_';</code>
-
-<p>Please note that all native CodeIgniter libraries are prefixed with <kbd>CI_</kbd> so DO NOT use that as your prefix.</p>
-
-
-<h2>Now What?</h2>
-
-<p>In the Table of Contents you'll find a list of all the available Helper Files.  Browse each one to see what they do.</p>

-<h1>Hooks - Extending the Framework Core</h1>
-
-<p>CodeIgniter's Hooks feature provides a means to tap into and modify the inner workings of the framework without hacking the core files.
-When CodeIgniter runs it follows a specific execution process, diagramed in the <a href="../overview/appflow.html">Application Flow</a> page.
-There may be instances, however, where you'd like to cause some action to take place at a particular stage in the execution process.
-For example, you might want to run a script right before your controllers get loaded, or right after, or you might want to trigger one of
-your own scripts in some other location.
-</p>
-
-<h2>Enabling Hooks</h2>
-
-<p>The hooks feature can be globally enabled/disabled by setting the following item in the <kbd>application/config/config.php</kbd> file:</p>
-
-<code>$config['enable_hooks'] = TRUE;</code>
-
-
-<h2>Defining a Hook</h2>
-
-<p>Hooks are defined in <dfn>application/config/hooks.php</dfn> file.  Each hook is specified as an array with this prototype:</p>
-
-<code>
-$hook['pre_controller'] = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class'&nbsp;&nbsp;&nbsp;&nbsp;=> 'MyClass',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'function' => 'Myfunction',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename' => 'Myclass.php',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filepath' => 'hooks',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'params'&nbsp;&nbsp;&nbsp;=> array('beer', 'wine', 'snacks')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);</code>
-
-<p><strong>Notes:</strong><br />The array index correlates to the name of the particular hook point you want to
-use.  In the above example the hook point is <kbd>pre_controller</kbd>. A list of hook points is found below.
-The following items should be defined in your associative hook array:</p>
-
-<ul>
-<li><strong>class</strong>&nbsp; The name of the class you wish to invoke. If you prefer to use a procedural function instead of a class, leave this item blank.</li>
-<li><strong>function</strong>&nbsp; The function name you wish to call.</li>
-<li><strong>filename</strong>&nbsp; The file name containing your class/function.</li>
-<li><strong>filepath</strong>&nbsp; The name of the directory containing your script.  Note: Your script must be located in a directory INSIDE your <kbd>application</kbd> folder, so the file path is relative to that folder.  For example, if your script is located in <dfn>application/hooks</dfn>, you will simply use <samp>hooks</samp> as your filepath.  If your script is located in <dfn>application/hooks/utilities</dfn> you will use <samp>hooks/utilities</samp> as your filepath. No trailing slash.</li>
-<li><strong>params</strong>&nbsp; Any parameters you wish to pass to your script. This item is optional.</li>
-</ul>
-
-
-<h2>Multiple Calls to the Same Hook</h2>
-
-<p>If want to use the same hook point with more then one script, simply make your array declaration multi-dimensional, like this:</p>
-
-<code>
-$hook['pre_controller']<kbd>[]</kbd> = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class'&nbsp;&nbsp;&nbsp;&nbsp;=> 'MyClass',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'function' => 'Myfunction',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename' => 'Myclass.php',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filepath' => 'hooks',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'params'&nbsp;&nbsp;&nbsp;=> array('beer', 'wine', 'snacks')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />

-
-<p>Notice the brackets after each array index:</p>
-
-<code>$hook['pre_controller']<kbd>[]</kbd></code>
-
-<p>This permits you to have the same hook point with multiple scripts.  The order you define your array will be the execution order.</p>
-
-
-<h2>Hook Points</h2>
-
-<p>The following is a list of available hook points.</p>
-
-<ul>
-		<li><strong>pre_system</strong><br />
-			Called very early during system execution.  Only the benchmark and hooks class have been loaded at this point. No routing or other processes have happened.</li>
-		<li><strong>pre_controller</strong><br />
-			Called immediately prior to any of your controllers being called. All base classes, routing, and security checks have been done.</li>
-		<li><strong>post_controller_constructor</strong><br />
-			Called immediately after your controller is instantiated, but prior to any method calls happening.</li>
-		<li><strong>post_controller</strong><br />
-			Called immediately after your controller is fully executed.</li>
-		<li><strong>display_override</strong><br />
-			Overrides the <dfn>_display()</dfn> function, used to send the finalized page to the web browser at the end of system execution.  This permits you to
-			use your own display methodology.  Note that you will need to reference the CI superobject with <dfn>$this->CI =&amp; get_instance()</dfn> and then the finalized data will be available by calling <dfn>$this->CI->output->get_output()</dfn></li>
-		<li><strong>cache_override</strong><br />
-			Enables you to call your own function instead of the <dfn>_display_cache()</dfn> function in the output class.  This permits you to use your own cache display mechanism.</li>
-		<li><strong>post_system</strong><br />
-			Called after the final rendered page is sent to the browser, at the end of system execution after the finalized data is sent to the browser.</li>
-	</ul>

-<h1>Using CodeIgniter Libraries</h1>
-
-
-<p>All of the available libraries are located in your <dfn>system/libraries</dfn> folder.
-In most cases, to use one of these classes involves initializing it within a <a href="controllers.html">controller</a> using the following initialization function:</p>
-
-<code>$this->load->library('<var>class name</var>'); </code>
-
-<p>Where <var>class name</var> is the name of the class you want to invoke.  For example, to load the form validation class you would do this:</p>
-
-<code>$this->load->library('<var>form_validation</var>'); </code>
-
-<p>Once initialized you can use it as indicated in the user guide page corresponding to that class.</p>
-
-<p>Additionally, multiple libraries can be loaded at the same time by passing an array of libraries to the load function.</p>
-
-<code>$this->load->library(array('<var>email</var>', '<var>table</var>'));</code>
-
-<h2>Creating Your Own Libraries</h2>

-<h1>Managing your Applications</h1>
-
-<p>By default it is assumed that you only intend to use CodeIgniter to manage one application, which you will build in your
-<dfn>application/</dfn> directory.  It is possible, however, to have multiple sets of applications that share a single
-CodeIgniter installation, or even to rename or relocate your <dfn>application</dfn> folder.</p>
-
-<h2>Renaming the Application Folder</h2>
-
-<p>If you would like to rename your <dfn>application</dfn> folder you may do so as long as you open your main <kbd>index.php</kbd>
-file and set its name using the <samp>$application_folder</samp> variable:</p>
-
-<code>$application_folder = "application";</code>
-
-<h2>Relocating your Application Folder</h2>
-
-<p>It is possible to move your <dfn>application</dfn> folder to a different location on your server than your <kbd>system</kbd> folder.
-To do so open your main <kbd>index.php</kbd> and set a <em>full server path</em> in the <samp>$application_folder</samp> variable.</p>
-
-
-<code>$application_folder = "/Path/to/your/application";</code>
-
-
-<h2>Running Multiple Applications with one CodeIgniter Installation</h2>
-
-<p>If you would like to share a common CodeIgniter installation to manage several different applications simply
-put all of the directories located inside your <kbd>application</kbd> folder into their
-own sub-folder.</p>
-
-<p>For example, let's say you want to create two applications, "foo" and "bar".  You could structure your
-application folders like this:</p>
-
-<code>applications/<var>foo</var>/<br />
-applications/<var>foo</var>/config/<br />
-applications/<var>foo</var>/controllers/<br />
-applications/<var>foo</var>/errors/<br />
-applications/<var>foo</var>/libraries/<br />
-applications/<var>foo</var>/models/<br />
-applications/<var>foo</var>/views/<br />
-applications/<samp>bar</samp>/<br />
-applications/<samp>bar</samp>/config/<br />
-applications/<samp>bar</samp>/controllers/<br />
-applications/<samp>bar</samp>/errors/<br />
-applications/<samp>bar</samp>/libraries/<br />
-applications/<samp>bar</samp>/models/<br />
-applications/<samp>bar</samp>/views/</code>
-
-
-<p>To select a particular application for use requires that you open your main <kbd>index.php</kbd> file and set the <dfn>$application_folder</dfn>
-variable.  For example, to select the "foo" application for use you would do this:</p>
-
-<code>$application_folder = "applications/foo";</code>
-
-<p class="important"><strong>Note:</strong>&nbsp; Each of your applications will need its own <dfn>index.php</dfn> file which
-calls the desired application.  The index.php file can be named anything you want.</p>

-<h2><a name="what"></a>What is a Model?</h2>
-
-<p>Models are PHP classes that are designed to work with information in your database.  For example, let's say
-you use CodeIgniter to manage a blog.  You might have a model class that contains functions to insert, update, and
-retrieve your blog data. Here is an example of what such a model class might look like:</p>
-
-<code>
-class&nbsp;Blogmodel&nbsp;extends&nbsp;CI_Model&nbsp;{<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;var $title&nbsp;&nbsp; = '';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;var $content = '';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;var $date&nbsp;&nbsp;&nbsp; = '';<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;__construct()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Call the Model constructor<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;get_last_ten_entries()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$query = $this->db->get('entries', 10);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return $query->result();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;insert_entry()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->title&nbsp;&nbsp; = $_POST['title']; // please read the below note<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->content = $_POST['content'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->date&nbsp;&nbsp;&nbsp; = time();<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->db->insert('entries',&nbsp;$this);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;update_entry()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->title&nbsp;&nbsp; = $_POST['title'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->content = $_POST['content'];<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->date&nbsp;&nbsp;&nbsp; = time();<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->db->update('entries',&nbsp;$this, array('id' => $_POST['id']));<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-<br />
-}</code>
-
-<p>Note: The functions in the above example use the <a href="../database/active_record.html">Active Record</a> database functions.</p>
-<p class="important"><strong>Note:</strong> For the sake of simplicity in this example we're using $_POST directly.  This is generally bad practice, and a more common approach would be to use the <a href="../libraries/input.html">Input Class</a> $this-&gt;input-&gt;post('title')</p>
-<h2><a name="anatomy"></a>Anatomy of a Model</h2>
-
-<p>Model classes are stored in your <dfn>application/models/</dfn> folder.  They can be nested within sub-folders if you
-want this type of organization.</p>
-
-<p>The basic prototype for a model class is this:</p>
-
-
-<code>
-class&nbsp;<var>Model_name</var>&nbsp;extends&nbsp;CI_Model&nbsp;{<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;<var>__construct</var>()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<p>Where <var>Model_name</var> is the name of your class.  Class names <strong>must</strong> have the first letter capitalized with the rest of the name lowercase.
-Make sure your class extends the base Model class.</p>
-
-<p>The file name will be a lower case version of your class name.  For example, if your class is this:</p>
-
-<code>
-class&nbsp;<var>User_model</var>&nbsp;extends&nbsp;CI_Model&nbsp;{<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;<var>__construct</var>()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}</code>
-
-<p>Your file will be this:</p>
-
-<code>application/models/<var>user_model.php</var></code>
-
-
-
-<h2><a name="loading"></a>Loading a Model</h2>
-
-<p>Your models will typically be loaded and called from within your <a href="controllers.html">controller</a> functions.
-To load a model you will use the following function:</p>
-
-<code>$this->load->model('<var>Model_name</var>');</code>
-
-<p>If your model is located in a sub-folder, include the relative path from your models folder.  For example, if
-you have a model located at <dfn>application/models/blog/queries.php</dfn> you'll load it using:</p>
-
-<code>$this->load->model('<var>blog/queries</var>');</code>
-
-
-<p>Once loaded, you will access your model functions using an object with the same name as your class:</p>
-
-<code>
-$this->load->model('<var>Model_name</var>');<br />
-<br />
-$this-><var>Model_name</var>->function();
-</code>
-
-<p>If you would like your model assigned to a different object name you can specify it via the second parameter of the loading
-function:</p>
-
-
-<code>
-$this->load->model('<var>Model_name</var>', '<kbd>fubar</kbd>');<br />
-<br />
-$this-><kbd>fubar</kbd>->function();
-</code>
-
-<p>Here is an example of a controller, that loads a model, then serves a view:</p>
-
-<code>
-class&nbsp;Blog_controller&nbsp;extends&nbsp;CI_Controller&nbsp;{<br />

-
-<h2><a name="auto_load_model" id="auto_load_model"></a>Auto-loading Models</h2>
-<p>If you find that you need a particular model globally throughout your  application, you can tell CodeIgniter to auto-load it during system  initialization.  This is done by opening the application/config/autoload.php file and adding the model to the autoload array.</p>
-
-
-<h2><a name="conn"></a>Connecting to your Database</h2>
-
-<p>When a model is loaded it does <strong>NOT</strong> connect automatically to your database.  The following options for connecting are available to you:</p>
-
-<ul>
-<li>You can connect using the standard database methods <a href="../database/connecting.html">described here</a>, either from within your Controller class or your Model class.</li>
-<li>You can tell the model loading function to auto-connect by passing <kbd>TRUE</kbd> (boolean) via the third parameter,
-and connectivity settings, as defined in your database config file will be used:
-
-	<code>$this->load->model('<var>Model_name</var>', '', <kbd>TRUE</kbd>);</code>
-	</li>
-
-
-<li>You can manually pass database connectivity settings via the third parameter:
-
-
-		<code>$config['hostname'] = "localhost";<br />
-		$config['username'] = "myusername";<br />
-		$config['password'] = "mypassword";<br />
-		$config['database'] = "mydatabase";<br />
-		$config['dbdriver'] = "mysql";<br />
-		$config['dbprefix'] = "";<br />
-		$config['pconnect'] = FALSE;<br />
-		$config['db_debug'] = TRUE;<br />
-		<br />
-		$this->load->model('<var>Model_name</var>', '', <kbd>$config</kbd>);</code></li>

-<h1>Profiling Your Application</h1>
-
-<p>The Profiler Class will display benchmark results, queries you have run, and $_POST data at the bottom of your pages.
-This information can be useful during development in order to help with debugging and optimization.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p class="important"><strong>Important:</strong>&nbsp; This class does <kbd>NOT</kbd> need to be initialized. It is loaded automatically by the
-<a href="../libraries/output.html">Output Class</a> if profiling is enabled as shown below.</p>
-
-<h2>Enabling the Profiler</h2>
-
-	<p>To enable the profiler place the following function anywhere within your <a href="controllers.html">Controller</a> functions:</p>
-	<code>$this->output->enable_profiler(TRUE);</code>
-
-	<p>When enabled a report will be generated and inserted at the bottom of your pages.</p>
-
-	<p>To disable the profiler you will use:</p>
-	<code>$this->output->enable_profiler(FALSE);</code>
-
-
-<h2>Setting Benchmark Points</h2>
-
-	<p>In order for the Profiler to compile and display your benchmark data you must name your mark points using specific syntax.</p>
-
-	<p>Please read the information on setting Benchmark points in <a href="../libraries/benchmark.html">Benchmark Class</a> page.</p>
-
-
-<h2>Enabling and Disabling Profiler Sections</h2>
-
-	<p>Each section of Profiler data can be enabled or disabled by setting a corresponding config variable to <var>TRUE</var> or <var>FALSE</var>.  This can be done one of two ways.  First, you can set application wide defaults with the <dfn>application/config/profiler.php</dfn> config file.</p>
-
-	<code>$config['config']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br />
-	$config['queries']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br /></code>
-
-	<p>In your controllers, you can override the defaults and config file values by calling the <kbd>set_profiler_sections()</kbd> method of the <a href="../libraries/output.html">Output class</a>:</p>
-
-	<code>$sections = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;'config' &nbsp;=> TRUE,<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;'queries' => TRUE<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-	<br />
-	$this->output->set_profiler_sections($sections);</code>
-
-	<p>Available sections and the array key used to access them are described in the table below.</p>
-
-	<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">

-<h1>Reserved Names</h1>
-
-<p>In order to help out, CodeIgniter uses a series of functions and names in its operation. Because of this, some names cannot be used by a developer. Following is a list of reserved names that cannot be used.</p>
-<h3>Controller names</h3>
-<p>Since your controller classes will extend the main application controller you
-must be careful not to name your functions identically to the ones used by that class, otherwise your local functions
-will override them.  The following
-is a list of reserved names.  Do not name your controller any of these:</p>
-<ul>
-	<li>Controller</li>
-	<li>CI_Base</li>
-	<li>_ci_initialize</li>
-	<li>Default</li>
-	<li>index</li>
-</ul>
-<h3>Functions</h3>
-<ul>
-	<li>is_really_writable()</li>
-	<li>load_class()</li>
-	<li>get_config()</li>
-	<li>config_item()</li>
-	<li>show_error()</li>
-	<li>show_404()</li>
-	<li>log_message()</li>
-	<li>_exception_handler()</li>
-	<li>get_instance()</li>
-	</ul>
-<h3>Variables</h3>
-<ul>
-	<li>$config</li>
-	<li>$mimes</li>
-	<li>$lang</li>
-</ul>
-<h3>Constants</h3>
-<ul>
-	<li>ENVIRONMENT</li>
-	<li>EXT</li>
-	<li>FCPATH</li>
-	<li>SELF</li>
-	<li>BASEPATH</li>
-	<li>APPPATH</li>
-	<li>CI_VERSION</li>
-	<li>FILE_READ_MODE</li>
-	<li>FILE_WRITE_MODE</li>
-	<li>DIR_READ_MODE</li>
-	<li>DIR_WRITE_MODE</li>
-	<li>FOPEN_READ</li>

-<h1>URI Routing</h1>
-
-<p>Typically there is a one-to-one relationship between a URL string and its corresponding controller class/method.
-The segments in a URI normally follow this pattern:</p>
-
-<code>example.com/<dfn>class</dfn>/<samp>function</samp>/<var>id</var>/</code>
-
-<p>In some instances, however, you may want to remap this relationship so that a different class/function can be called
-instead of the one corresponding to the URL.</p>
-
-<p>For example, lets say you want your URLs to have this prototype:</p>
-
-<p>
-example.com/product/1/<br />
-example.com/product/2/<br />
-example.com/product/3/<br />
-example.com/product/4/
-</p>
-
-<p>Normally the second segment of the URL is reserved for the function name, but in the example above it instead has a product ID.
-To overcome this, CodeIgniter allows you to remap the URI handler.</p>
-
-
-<h2>Setting your own routing rules</h2>
-
-<p>Routing rules are defined in your <var>application/config/routes.php</var> file.  In it you'll see an array called <dfn>$route</dfn> that
-permits you to specify your own routing criteria. Routes can either be specified using <dfn>wildcards</dfn> or <dfn>Regular Expressions</dfn></p>
-
-
-<h2>Wildcards</h2>
-
-<p>A typical wildcard route might look something like this:</p>
-
-<code>$route['product/:num'] = "catalog/product_lookup";</code>
-
-<p>In a route, the array key contains the URI to be matched, while the array value  contains the destination it should be re-routed to.
-In the above example, if the literal word "product" is found in the first segment of the URL, and a number is found in the second segment,
-the "catalog" class and the "product_lookup" method are instead used.</p>
-
-<p>You can match literal values or you can use two wildcard types:</p>
-
-<p><strong>(:num)</strong> will match a segment containing only numbers.<br />
-<strong>(:any)</strong> will match a segment containing any character.
-</p>
-
-<p class="important"><strong>Note:</strong> Routes will run in the order they are defined.
-Higher routes will always take precedence over lower ones.</p>
-
-<h2>Examples</h2>
-
-<p>Here are a few routing examples:</p>
-
-<code>$route['journals'] = "blogs";</code>
-<p>A URL containing the word "journals" in the first segment will be remapped to the "blogs" class.</p>
-
-<code>$route['blog/joe'] = "blogs/users/34";</code>
-<p>A URL containing the segments blog/joe will be remapped to the "blogs" class and the "users" method.  The ID will be set to "34".</p>
-
-<code>$route['product/(:any)'] = "catalog/product_lookup";</code>
-<p>A URL with "product" as the first segment, and anything in the second will be remapped to the "catalog" class and the  "product_lookup" method.</p>
-
-<code>$route['product/(:num)'] = "catalog/product_lookup_by_id/$1";</code>
-<p>A URL with "product" as the first segment, and a number in the second will be remapped to the "catalog" class and the "product_lookup_by_id" method passing in the match as a variable to the function.</p>
-
-<p class="important"><strong>Important:</strong> Do not use leading/trailing slashes.</p>
-
-<h2>Regular Expressions</h2>
-
-<p>If you prefer you can use regular expressions to define your routing rules.  Any valid regular expression is allowed, as are back-references.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; If you use back-references you must use the dollar syntax rather than the double backslash syntax.</p>
-
-<p>A typical RegEx route might look something like this:</p>
-
-<code>$route['products/([a-z]+)/(\d+)'] = "$1/id_$2";</code>
-
-<p>In the above example, a URI similar to <dfn>products/shirts/123</dfn> would instead call the <dfn>shirts</dfn> controller class and the <dfn>id_123</dfn> function.</p>
-
-<p>You can also mix and match wildcards with regular expressions.</p>
-
-<h2>Reserved Routes</h2>
-
-<p>There are two reserved routes:</p>
-
-<code>$route['default_controller'] = 'welcome';</code>
-
-<p>This route indicates which controller class should be loaded if the URI contains no data, which will be the case
-when people load your root URL. In the above example, the "welcome" class would be loaded.  You
-are encouraged to always have a default route otherwise a 404 page will appear by default.</p>
-
-<code>$route['404_override'] = '';</code>
-
-<p>This route indicates which controller class should be loaded if the requested controller is not found. It will override the default 404
-error page. It won't affect to the <samp>show_404()</samp> function, which will continue loading the default <dfn>error_404.php</dfn> file at <var>application/errors/error_404.php</var>.</p>
-
-<p class="important"><strong>Important:</strong>&nbsp; The reserved routes must come before any wildcard or regular expression routes.</p>

-<h1>Security</h1>
-
-<p>This page describes some "best practices" regarding web security, and details
-CodeIgniter's internal security features.</p>
-
-
-<h2>URI Security</h2>
-
-<p>CodeIgniter is fairly restrictive regarding which characters it allows in your URI strings in order to help
-minimize the possibility that malicious data can be passed to your application.  URIs may only contain the following:
-</p>
-
-<ul>
-<li>Alpha-numeric text</li>
-<li>Tilde: ~ </li>
-<li>Period: .</li>
-<li>Colon: :</li>
-<li>Underscore: _</li>
-<li>Dash: -</li>
-</ul>
-
-<h2>Register_globals</h2>
-
-<p>During system initialization all global variables are unset, except those found in the $_GET, $_POST, and $_COOKIE arrays. The unsetting
-routine is effectively the same as register_globals = off.</p>
-
-<a name="error_reporting"></a>
-<h2>error_reporting</h2>
-
-<p>
-    In production environments, it is typically desirable to disable PHP's 
-    error reporting by setting the internal error_reporting flag to a value of 0. This disables native PHP
-    errors from being rendered as output, which may potentially contain
-    sensitive information.
-</p>
-
-<p>
-    Setting CodeIgniter's <kbd>ENVIRONMENT</kbd> constant in index.php to a
-    value of '<kbd>production</kbd>' will turn off these errors. In development
-    mode, it is recommended that a value of '<kbd>development</kbd>' is used.
-    More information about differentiating between environments can be found
-    on the <a href="environments.html">Handling Environments</a> page.
-</p>
-
-<h2>magic_quotes_runtime</h2>
-
-<p>The magic_quotes_runtime directive is turned off during system initialization so that you don't have to remove slashes when
-retrieving data from your database.</p>
-
-<h1>Best Practices</h1>
-
-<p>Before accepting any data into your application, whether it be POST data from a form submission, COOKIE data, URI data,
-XML-RPC data, or even data from the SERVER array, you are encouraged to practice this three step approach:</p>
-
-<ol>
-<li>Filter the data as if it were tainted.</li>
-<li>Validate the data to ensure it conforms to the correct  type, length, size, etc. (sometimes this step can replace step one)</li>
-<li>Escape the data before submitting it into your database.</li>
-</ol>
-
-<p>CodeIgniter provides the following functions to assist in this process:</p>
-
-<ul>
-
-<li><h2>XSS Filtering</h2>
-
-<p>CodeIgniter comes with a Cross Site Scripting filter.  This filter looks for commonly
-used techniques to embed malicious Javascript into your data, or other types of code that attempt to hijack cookies
-or do other malicious things. The XSS Filter is described <a href="../libraries/security.html">here</a>.
-</p>
-</li>
-
-<li><h2>Validate the data</h2>
-
-<p>CodeIgniter has a <a href="../libraries/form_validation.html">Form Validation Class</a> that assists you in validating, filtering, and prepping
-your data.</p>
-</li>
-
-<li><h2>Escape all data before database insertion</h2>
-
-<p>Never insert information into your database without escaping it. Please see the section that discusses
-<a href="../database/queries.html">queries</a> for more information.</p>
-
-</li>
-
-</ul>

-		<div class="guidelineDetails">
-			<p>The PHP closing tag on a PHP document <strong>?&gt;</strong> is optional to the PHP parser.  However, if used, any whitespace following the closing tag, whether introduced
-				by the developer, user, or an FTP application, can cause unwanted output, PHP errors, or if the latter are suppressed, blank pages.  For this reason, all PHP files should
-				<strong>OMIT</strong> the closing PHP tag, and instead use a comment block to mark the end of file and it's location relative to the application root.
-				This allows you to still identify a file as being complete and not truncated.</p>
-<code><strong>INCORRECT</strong>:

-		<h2><a name="class_and_method_naming"></a>Class and Method Naming</h2>
-		<div class="guidelineDetails">
-			<p>Class names should always start with an uppercase letter.  Multiple words should be separated with an underscore, and not CamelCased.  All other class methods should be entirely lowercased and named to clearly indicate their function, preferably including a verb.  Try to avoid overly long and verbose names.</p>

-
-			<p>Examples of improper and proper method naming:</p>
-
-	<code><strong>INCORRECT</strong>:

-		<h2><a name="variable_names"></a>Variable Names</h2>
-		<div class="guidelineDetails">
-			<p>The guidelines for variable naming is very similar to that used for class methods.  Namely, variables should contain only lowercase letters, use underscore separators, and be reasonably named to indicate their purpose and contents. Very short, non-word variables should only be used as iterators in for() loops.</p>
-<code><strong>INCORRECT</strong>:
-$j = &apos;foo&apos;;		// single letter variables should only be used in for() loops
-$Str			// contains uppercase letters
-$bufferedText		// uses CamelCasing, and could be shortened without losing semantic meaning
-$groupid		// multiple words, needs underscore separator
-$name_of_last_city_used	// too long
-
-<strong>CORRECT</strong>:
-for ($j = 0; $j &lt; 10; $j++)
-$str
-$buffer
-$group_id
-$last_city

-		</div>
-
-
-		<h2><a name="commenting"></a>Commenting</h2>
-		<div class="guidelineDetails">
-			<p>In general, code should be commented prolifically.  It not only helps describe the flow and intent of the code for less experienced programmers, but can prove invaluable when returning to your own code months down the line.  There is not a required format for comments, but the following are recommended.</p>
-
-			<p><a href="http://manual.phpdoc.org/HTMLSmartyConverter/HandS/phpDocumentor/tutorial_phpDocumentor.howto.pkg.html#basics.docblock">DocBlock</a> style comments preceding class and method declarations so they can be picked up by IDEs:</p>
-
-<code>/**
- * Super Class
- *
- * @package	Package Name
- * @subpackage	Subpackage
- * @category	Category
- * @author	Author Name
- * @link	http://example.com
- */
-class Super_class {</code>
-
-<code>/**
- * Encodes string for use in XML
- *
- * @access	public
- * @param	string
- * @return	string
- */
-function xml_encode($str)</code>
-
-			<p>Use single line comments within code, leaving a blank line between large comment blocks and code.</p>
-
-<code>// break up the string by newlines
-$parts = explode("\n", $str);
-
-// A longer comment that needs to give greater detail on what is
-// occurring and why can use multiple single-line comments.  Try to
-// keep the width reasonable, around 70 characters is the easiest to
-// read.  Don't hesitate to link to permanent external resources
-// that may provide greater detail:
-//

-$parts = $this->foo($parts);

-		<h2><a name="constants"></a>Constants</h2>
-		<div class="guidelineDetails">
-			<p>Constants follow the same guidelines as do variables, except constants should always be fully uppercase.  <em>Always use CodeIgniter constants when appropriate, i.e. SLASH, LD, RD, PATH_CACHE, etc.</em></p>
-<code><strong>INCORRECT</strong>:
-myConstant	// missing underscore separator and not fully uppercase
-N		// no single-letter constants
-S_C_VER		// not descriptive

-		<h2><a name="comparing_return_values_and_typecasting"></a>Comparing Return Values and Typecasting</h2>
-		<div class="guidelineDetails">
-			<p>Some PHP functions return FALSE on failure, but may also have a valid return value of "" or 0, which would evaluate to FALSE in loose comparisons.  Be explicit by comparing the variable type when using these return values in conditionals to ensure the return value is indeed what you expect, and not a value that has an equivalent loose-type evaluation.</p>
-			<p>Use the same stringency in returning and checking your own variables.  Use <strong>===</strong> and <strong>!==</strong> as necessary.
-
-<code><strong>INCORRECT</strong>:
-// If 'foo' is at the beginning of the string, strpos will return a 0,
-// resulting in this conditional evaluating as TRUE
-if (strpos($str, 'foo') == FALSE)
-
-<strong>CORRECT</strong>:
-if (strpos($str, 'foo') === FALSE)
-</code>
-
-<code><strong>INCORRECT</strong>:
-function build_string($str = "")
-{
-	if ($str == "")	// uh-oh!  What if FALSE or the integer 0 is passed as an argument?
-	{
-
-	}
-}
-
-<strong>CORRECT</strong>:
-function build_string($str = "")
-{
-	if ($str === "")
-	{
-
-	}
-}</code>
-
-		<p>See also information regarding <a href="http://us3.php.net/manual/en/language.types.type-juggling.php#language.types.typecasting">typecasting</a>, which can be quite useful.  Typecasting has a slightly different effect which may be desirable.  When casting a variable as a string, for instance, NULL and boolean FALSE variables become empty strings, 0 (and other numbers) become strings of digits, and boolean TRUE becomes "1":</p>

-		<div class="guidelineDetails">
-			<p>No debugging code can be left in place for submitted add-ons unless it is commented out, i.e. no var_dump(), print_r(), die(), and exit() calls that were used while creating the add-on, unless they are commented out.</p>

-
-
-
-		<h2><a name="whitespace_in_files"></a>Whitespace in Files</h2>
-		<div class="guidelineDetails">
-			<p>No whitespace can precede the opening PHP tag or follow the closing PHP tag.  Output is buffered, so whitespace in your files can cause output to begin before CodeIgniter outputs its content, leading to errors and an inability for CodeIgniter to send proper headers.  In the examples below, select the text with your mouse to reveal the incorrect whitespace.</p>
-
-			<p><strong>INCORRECT</strong>:</p>
-<code>
-&lt;?php
-	// ...there is whitespace and a linebreak above the opening PHP tag
-	// as well as whitespace after the closing PHP tag
-?&gt;
-</code>
-			<p><strong>CORRECT</strong>:</p>
-<code>&lt;?php

-
-		</div>
-
-
-		<h2><a name="compatibility"></a>Compatibility</h2>
-		<div class="guidelineDetails">
-			<p>Unless specifically mentioned in your add-on's documentation, all code must be compatible with PHP version 5.1+.  Additionally, do not use PHP functions that require non-default libraries to be installed unless your code contains an alternative method when the function is not available, or you implicitly document that your add-on requires said PHP libraries.</p>
-		</div>
-
-
-
-		<h2><a name="class_and_file_names_using_common_words"></a>Class and File Names using Common Words</h2>
-		<div class="guidelineDetails">
-			<p>When your class or filename is a common word, or might quite likely be identically named in another PHP script, provide a unique prefix to help prevent collision.  Always realize that your end users may be running other add-ons or third party PHP scripts.  Choose a prefix that is unique to your identity as a developer or company.</p>
-
-<code><strong>INCORRECT</strong>:
-class Email		pi.email.php
-class Xml		ext.xml.php
-class Import		mod.import.php
-
-<strong>CORRECT</strong>:
-class Pre_email		pi.pre_email.php

-class Pre_import	mod.pre_import.php
-</code>
-		</div>
-
-
-		<h2><a name="database_table_names"></a>Database Table Names</h2>
-		<div class="guidelineDetails">
-			<p>Any tables that your add-on might use must use the 'exp_' prefix, followed by a prefix uniquely identifying you as the developer or company, and then a short descriptive table name.  You do not need to be concerned about the database prefix being used on the user's installation, as CodeIgniter's database class will automatically convert 'exp_' to what is actually being used.</p>
-
-<code><strong>INCORRECT</strong>:
-email_addresses		// missing both prefixes
-pre_email_addresses	// missing exp_ prefix
-exp_email_addresses	// missing unique prefix
-
-<strong>CORRECT</strong>:
-exp_pre_email_addresses
-</code>
-
-			<p class="important"><strong>NOTE:</strong> Be mindful that MySQL has a limit of 64 characters for table names.  This should not be an issue as table names that would exceed this would likely have unreasonable names.  For instance, the following table name exceeds this limitation by one character.  Silly, no? <strong>exp_pre_email_addresses_of_registered_users_in_seattle_washington</strong>
-		</div>
-
-
-
-		<h2><a name="one_file_per_class"></a>One File per Class</h2>
-		<div class="guidelineDetails">
-			<p>Use separate files for each class your add-on uses, unless the classes are <em>closely related</em>.  An example of CodeIgniter files that contains multiple classes is the Database class file, which contains both the DB class and the DB_Cache class, and the Magpie plugin, which contains both the Magpie and Snoopy classes.</p>
-		</div>
-
-
-
-		<h2><a name="whitespace"></a>Whitespace</h2>
-		<div class="guidelineDetails">
-			<p>Use tabs for whitespace in your code, not spaces.  This may seem like a small thing, but using tabs instead of whitespace allows the developer looking at your code to have indentation at levels that they prefer and customize in whatever application they use.  And as a side benefit, it results in (slightly) more compact files, storing one tab character versus, say, four space characters.</p>
-		</div>
-
-
-
-		<h2><a name="line_breaks"></a>Line Breaks</h2>
-		<div class="guidelineDetails">
-			<p>Files must be saved with Unix line breaks.  This is more of an issue for developers who work in Windows, but in any case ensure that your text editor is setup to save files with Unix line breaks.</p>

-<h1>CodeIgniter URLs</h1>
-
-<p>By default, URLs in CodeIgniter are designed to be search-engine and human friendly.  Rather than using the standard "query string"
-approach to URLs that is synonymous with dynamic systems, CodeIgniter uses a <strong>segment-based</strong> approach:</p>
-
-<code>example.com/<var>news</var>/<dfn>article</dfn>/<samp>my_article</samp></code>
-
-<p class="important"><strong>Note:</strong> Query string URLs can be optionally enabled, as described below.</p>
-
-<h2>URI Segments</h2>
-
-<p>The segments in the URL, in following with the Model-View-Controller approach, usually represent:</p>
-
-<code>example.com/<var>class</var>/<dfn>function</dfn>/<samp>ID</samp></code>
-
-<ol>
-<li>The first segment represents the controller <strong>class</strong> that should be invoked.</li>
-<li>The second segment represents the class <strong>function</strong>, or method, that should be called.</li>
-<li>The third, and any additional segments, represent the ID and any variables that will be passed to the controller.</li>
-</ol>
-
-<p>The <a href="../libraries/uri.html">URI Class</a> and the <a href="../helpers/url_helper.html">URL Helper</a>
-contain functions that make it easy to work with your URI data.  In addition, your URLs can be remapped using the
-<a href="routing.html">URI Routing</a> feature for more flexibility.</p>
-
-
-
-<h2>Removing the index.php file</h2>
-
-<p>By default, the <strong>index.php</strong> file will be included in your URLs:</p>
-
-<code>example.com/<var>index.php</var>/news/article/my_article</code>
-
-<p>You can easily remove this file by using a .htaccess file with some simple rules. Here is an example
- of such a file, using the "negative" method in which everything is redirected except the specified items:</p>
-
-<code>RewriteEngine on<br />
-RewriteCond $1 !^(index\.php|images|robots\.txt)<br />
-RewriteRule ^(.*)$ /index.php/$1 [L]</code>
-
-<p>In the above example, any HTTP request other than those for index.php, images, and robots.txt is treated as
-a request for your index.php file.</p>
-
-
-<h2>Adding a URL Suffix</h2>
-
-<p>In your <dfn>config/config.php</dfn> file you can specify a suffix that will be added to all URLs generated
-by CodeIgniter.  For example, if a URL is this:</p>
-
-<code>example.com/index.php/products/view/shoes</code>
-
-<p>You can optionally add a suffix, like <kbd>.html</kbd>, making the page appear to be of a certain type:</p>
-
-<code>example.com/index.php/products/view/shoes.html</code>
-
-
-<h2>Enabling Query Strings</h2>
-
-<p>In some cases you might prefer to use query strings URLs:</p>
-
-<code>index.php?c=products&amp;m=view&amp;id=345</code>
-
-<p>CodeIgniter optionally supports this capability, which can be enabled in your <dfn>application/config.php</dfn> file. If you
-open your config file you'll see these items:</p>
-
-<code>$config['enable_query_strings'] = FALSE;<br />
-$config['controller_trigger'] = 'c';<br />
-$config['function_trigger'] = 'm';</code>
-
-<p>If you change "enable_query_strings" to TRUE this feature will become active.  Your controllers and functions will then
-be accessible using the "trigger" words you've set to invoke your controllers and methods:</p>
-
-<code>index.php?c=controller&amp;m=method</code>
-
-<p class="important"><strong>Please note:</strong> If you are using query strings you will have to build your own URLs, rather than utilizing
-the URL helpers (and other helpers that generate URLs, like some of the form helpers) as these are designed to work with
-segment based URLs.</p>

-<h1>Views</h1>
-
-<p>A <dfn>view</dfn> is simply a web page, or a page fragment, like a header, footer, sidebar, etc.
-In fact, views can flexibly be embedded within other views (within other views, etc., etc.) if you need this type
-of hierarchy.</p>
-
-<p>Views are never called directly, they must be loaded by a <a href="controllers.html">controller</a>.  Remember that in an MVC framework, the Controller acts as the
-traffic cop, so it is responsible for fetching a particular view. If you have not read the <a href="controllers.html">Controllers</a> page
-you should do so before continuing.</p>
-
-<p>Using the example controller you created in the <a href="controllers.html">controller</a> page, let's add a view to it.</p>
-
-<h2>Creating a View</h2>
-
-<p>Using your text editor, create a file called <dfn>blogview.php</dfn>, and put this in it:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;html>
-&lt;head>
-&lt;title>My Blog&lt;/title>
-&lt;/head>
-&lt;body>
-	&lt;h1>Welcome to my Blog!&lt;/h1>
-&lt;/body>
-&lt;/html>
-</textarea>
-
-<p>Then save the file in your <dfn>application/views/</dfn> folder.</p>
-
-<h2>Loading a View</h2>
-
-<p>To load a particular view file you will use the following function:</p>
-
-<code>$this->load->view('<var>name</var>');</code>
-
-<p>Where <var>name</var> is the name of your view file.  Note: The .php file extension does not need to be specified unless you use something other than <kbd>.php</kbd>.</p>
-
-
-<p>Now, open the controller file you made earlier called <dfn>blog.php</dfn>, and replace the echo statement with the view loading function:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;?php
-class Blog extends CI_Controller {
-
-	function index()
-	{
-		$this->load->view('blogview');
-	}
-}
-?&gt;
-</textarea>
-
-
-<p>If you visit your site using the URL you did earlier you should see your new view.  The URL was similar to this:</p>
-
-<code>example.com/index.php/<var>blog</var>/</code>
-
-<h2>Loading multiple views</h2>
-<p>CodeIgniter will intelligently handle  multiple calls to $this-&gt;load-&gt;view from within a controller.  If more than one call happens they will be appended together. For example, you may wish to have a header view, a menu view, a content view, and a footer view. That might look something like this:</p>
-<p><code>&lt;?php<br />
-<br />
-class Page extends CI_Controller {<br /><br />
-
- &nbsp;&nbsp;&nbsp;function index()<br />
-&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$data['page_title'] =  'Your title';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('header');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('menu');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('content', $data);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('footer');<br />
-&nbsp;&nbsp;&nbsp;}<br />
-<br />
-}<br />
-	?&gt;</code></p>
-<p>In the example above, we are using &quot;dynamically added data&quot;, which you will see below.</p>
-<h2>Storing Views within Sub-folders</h2>
-<p>Your view files can also be stored within sub-folders if you prefer that type of organization.  When doing so you will need
-to include the folder name loading the view.  Example:</p>
-
-<code>$this->load->view('<kbd>folder_name</kbd>/<var>file_name</var>');</code>
-
-
-<h2>Adding Dynamic Data to the View</h2>
-
-<p>Data is passed from the controller to the view by way of an <strong>array</strong> or an <strong>object</strong> in the second
-parameter of the view loading function. Here is an example using an array:</p>
-
-<code>$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'My Title',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading' => 'My Heading',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'message' => 'My Message'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->load->view('blogview', <var>$data</var>);</code>
-
-<p>And here's an example using an object:</p>
-
-<code>$data = new Someclass();<br />
-$this->load->view('blogview', <var>$data</var>);</code>
-
-<p>Note: If you use an object, the class variables will be turned into array elements.</p>
-
-
-<p>Let's try it with your controller file.  Open it add this code:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="14">
-&lt;?php
-class Blog extends CI_Controller {
-
-	function index()
-	{
-		$data['title'] = "My Real Title";
-		$data['heading'] = "My Real Heading";
-
-		$this->load->view('blogview', $data);
-	}
-}
-?&gt;
-</textarea>
-
-
-<p>Now open your view file and change the text to variables that correspond to the array keys in your data:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;html>
-&lt;head>
-&lt;title>&lt;?php echo $title;?>&lt;/title>
-&lt;/head>
-&lt;body>
-	&lt;h1>&lt;?php echo $heading;?>&lt;/h1>
-&lt;/body>
-&lt;/html>
-</textarea>
-
-<p>Then load the page at the URL you've been using and you should see the variables replaced.</p>
-
-<h2>Creating Loops</h2>
-
-<p>The data array you pass to your view files is not limited to simple variables.  You can
-pass multi dimensional arrays, which can be looped to generate multiple rows.  For example, if you
-pull data from your database it will typically be in the form of a multi-dimensional array.</p>
-
-<p>Here's a simple example. Add this to your controller:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="17">
-&lt;?php
-class Blog extends CI_Controller {
-
-	function index()
-	{
-		$data['todo_list'] = array('Clean House', 'Call Mom', 'Run Errands');
-
-		$data['title'] = "My Real Title";
-		$data['heading'] = "My Real Heading";
-
-		$this->load->view('blogview', $data);
-	}
-}
-?&gt;
-</textarea>
-
-
-<p>Now open your view file and create a loop:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="24">
-&lt;html>
-&lt;head>
-&lt;title>&lt;?php echo $title;?>&lt;/title>
-&lt;/head>
-&lt;body>
-&lt;h1>&lt;?php echo $heading;?>&lt;/h1>
-
-&lt;h3>My Todo List&lt;/h3>
-
-&lt;ul>
-&lt;?php foreach ($todo_list as $item):?>
-
-&lt;li>&lt;?php echo $item;?>&lt;/li>
-
-&lt;?php endforeach;?>
-&lt;/ul>
-
-&lt;/body>
-&lt;/html>
-</textarea>
-<p><strong>Note:</strong> You'll notice that in the example above we are using PHP's alternative syntax.  If you
-are not familiar with it you can read about it <a href="alternative_php.html">here</a>.</p>
-
-<h2>Returning views as data</h2>
-
-<p>There is a third <strong>optional</strong> parameter lets you change the behavior of the function so that it returns data as a string
-rather than sending it to your browser.  This can be useful if you want to process the data in some way.  If you
-set the parameter to <kbd>true</kbd> (boolean) it will return data.  The default behavior is <kbd>false</kbd>, which sends it
-to your browser.  Remember to assign it to a variable if you want the data returned:</p>
-
-<code>$string = $this->load->view('<var>myfile</var>', '', <kbd>true</kbd>);</code>

-<h1>Array Helper</h1>
-
-<p>The Array Helper file contains functions that assist in working with arrays.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('array');</code>
-
-<p>The following functions are available:</p>
-
-<h2>element()</h2>
-
-<p>Lets you fetch an item from an array.  The function tests whether the array index is set and whether it has a value.  If
-a value exists it is returned.  If a value does not exist it returns FALSE, or whatever you've specified as the default value via the third parameter.  Example:</p>
-
-<code>
-$array = array('color' => 'red', 'shape' => 'round', 'size' => '');<br />
-<br />
-// returns "red"<br />
-echo element('color', $array);<br />
-<br />
-// returns NULL<br />
-echo element('size', $array, NULL);
-</code>
-
-
-<h2>random_element()</h2>
-
-<p>Takes an array as input and returns a random element from it.  Usage example:</p>
-
-<code>$quotes = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"I find that the harder I work, the more luck I seem to have. - Thomas Jefferson",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Don't stay in bed, unless you can make money in bed. - George Burns",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"We didn't lose the game; we just ran out of time. - Vince Lombardi",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"If everything seems under control, you're not going fast enough. - Mario Andretti",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Reality is merely an illusion, albeit a very persistent one. - Albert Einstein",<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"Chance favors the prepared mind - Louis Pasteur"<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo random_element($quotes);</code>
-
-
-<h2>elements()</h2>
-
-<p>Lets you fetch a number of items from an array.  The function tests whether each of the array indices is set.  If an index does not exist
-it is set to FALSE, or whatever you've specified as the default value via the third parameter.  Example:</p>
-
-<code>
-$array = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'radius' => '10',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'diameter' => '20'<br />
-);<br />
-<br />
-$my_shape = elements(array('color', 'shape', 'height'), $array);<br />
-</code>
-
-<p>The above will return the following array:</p>
-
-<code>
-array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'height' => FALSE<br />
-);
-</code>
-
-<p>You can set the third parameter to any default value you like:</p>
-
-<code>
-$my_shape = elements(array('color', 'shape', 'height'), $array, NULL);<br />
-</code>
-
-<p>The above will return the following array:</p>
-
-<code>
-array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'height' => NULL<br />
-);
-</code>
-
-<p>This is useful when sending the <kbd>$_POST</kbd> array to one of your Models.  This prevents users from
-sending additional POST data to be entered into your tables:</p>
-
-<code>
-$this->load->model('post_model');<br />
-<br />
-$this->post_model->update(elements(array('id', 'title', 'content'), $_POST));
-</code>
-
-<p>This ensures that only the id, title and content fields are sent to be updated.</p>

-
-<code>$vals = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'word'		 => 'Random word',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'img_path'	 => './captcha/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'img_url'	 => 'http://example.com/captcha/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'font_path'	 => './path/to/fonts/texb.ttf',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'img_width'	 => '150',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'img_height' => 30,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'expiration' => 7200<br />
-&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$cap = create_captcha($vals);<br />
-echo $cap['image'];</code>
-
-	<ul>
-		<li>The captcha function requires the GD image library.</li>
-		<li>Only the img_path and img_url are required.</li>
-		<li>If a "word" is not supplied, the function will generate a random
-		ASCII string.  You might put together your own word library that
-		you can draw randomly from.</li>
-		<li>If you do not specify a path to a TRUE TYPE font, the native ugly GD
-		font will be used.</li>
-		<li>The "captcha" folder must be writable (666, or 777)</li>
-		<li>The "expiration" (in seconds) signifies how long an image will
-		remain in the captcha folder before it will be deleted.  The default
-		is two hours.</li>
-	</ul>
-
-	<h3>Adding a Database</h3>
-
-	<p>In order for the captcha function to prevent someone from submitting, you will need
-	to add the information returned from <kbd>create_captcha()</kbd> function to your database.
-	Then, when the data from the form is submitted by the user you will need to verify
-	that the data exists in the database and has not expired.</p>
-
-	<p>Here is a table prototype:</p>
-
-<code>CREATE TABLE captcha (<br />
-&nbsp;captcha_id bigint(13) unsigned NOT NULL auto_increment,<br />
-&nbsp;captcha_time int(10) unsigned NOT NULL,<br />
-&nbsp;ip_address varchar(16) default '0' NOT NULL,<br />
-&nbsp;word varchar(20) NOT NULL,<br />
-&nbsp;PRIMARY KEY `captcha_id` (`captcha_id`),<br />
-&nbsp;KEY `word` (`word`)<br />
-);</code>
-
-	<p>Here is an example of usage with a database.  On the page where the CAPTCHA will be shown you'll have something like this:</p>
-
-<code>$this-&gt;load-&gt;helper(&#x27;captcha&#x27;);<br />
-$vals = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&#x27;img_path&#x27;	 =&gt; &#x27;./captcha/&#x27;,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&#x27;img_url&#x27;	 =&gt; &#x27;http://example.com/captcha/&#x27;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$cap = create_captcha($vals);<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&#x27;captcha_time&#x27;	=&gt; $cap[&#x27;time&#x27;],<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&#x27;ip_address&#x27;	=&gt; $this-&gt;input-&gt;ip_address(),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&#x27;word&#x27;			=&gt; $cap[&#x27;word&#x27;]<br />
-&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$query = $this-&gt;db-&gt;insert_string(&#x27;captcha&#x27;, $data);<br />
-$this-&gt;db-&gt;query($query);<br />
-<br />
-echo &#x27;Submit the word you see below:&#x27;;<br />
-echo $cap[&#x27;image&#x27;];<br />
-echo &#x27;&lt;input type=&quot;text&quot; name=&quot;captcha&quot; value=&quot;&quot; /&gt;&#x27;;</code>
-
-	<p>Then, on the page that accepts the submission you'll have something like this:</p>
-
-<code>// First, delete old captchas<br />
-$expiration = time()-7200; // Two hour limit<br />
-$this-&gt;db-&gt;query(&quot;DELETE FROM captcha WHERE captcha_time &lt; &quot;.$expiration);	<br />
-<br />
-// Then see if a captcha exists:<br />
-$sql = &quot;SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND captcha_time &gt; ?&quot;;<br />
-$binds = array($_POST[&#x27;captcha&#x27;], $this-&gt;input-&gt;ip_address(), $expiration);<br />
-$query = $this-&gt;db-&gt;query($sql, $binds);<br />
-$row = $query-&gt;row();<br />
-<br />
-if ($row-&gt;count == 0)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo &quot;You must submit the word that appears in the image&quot;;<br />
-}</code>

-<h1>Date Helper</h1>
-
-<p>The Date Helper file contains functions that help you work with dates.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('date');</code>
-
-
-<p>The following functions are available:</p>
-
-<h2>now()</h2>
-
-<p>Returns the current time as a Unix timestamp, referenced either to your server's local time or GMT, based on the "time reference"
-setting in your config file.  If you do not intend to set your master time reference to GMT (which you'll typically do if you
-run a site that lets each user set their own timezone settings) there is no benefit to using this function over PHP's time() function.
-</p>
-
-
-
-
-<h2>mdate()</h2>
-
-<p>This function is identical to PHPs <a href="http://www.php.net/date">date()</a> function, except that it lets you
-use MySQL style date codes, where each code letter is preceded with a percent sign:  %Y %m %d etc.</p>
-
-<p>The benefit of doing dates this way is that you don't have to worry about escaping any characters that
-are not date codes, as you would normally have to do with the date() function.  Example:</p>
-
-<code>$datestring = "Year: %Y Month: %m Day: %d - %h:%i %a";<br />
-$time = time();<br />
-<br />
-echo mdate($datestring, $time);</code>
-
-<p>If a timestamp is not included in the second parameter the current time will be used.</p>
-
-
-<h2>standard_date()</h2>
-
-<p>Lets you generate a date string in one of several standardized formats. Example:</p>
-
-<code>
-$format = 'DATE_RFC822';<br />
-$time = time();<br />
-<br />
-echo standard_date($format, $time);
-</code>
-
-<p>The first parameter must contain the format, the second parameter must contain the date as a Unix timestamp.</p>
-
-<p>Supported formats:</p>
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">
-	<tr>
-		<th>Constant</th>
-		<th>Description</th>
-		<th>Example</th>
-	</tr>

-		<td>2005-08-14T16:13:03+0000</td>

-</table>
-
-<h2>local_to_gmt()</h2>
-
-<p>Takes a Unix timestamp as input and returns it as GMT.  Example:</p>
-
-<code>$now = time();<br />
-<br />
-$gmt = local_to_gmt($now);</code>
-
-
-<h2>gmt_to_local()</h2>
-
-<p>Takes a Unix timestamp (referenced to GMT) as input, and converts it to a localized timestamp based on the
-timezone and Daylight Saving time submitted.  Example:</p>
-
-<code>
-$timestamp = '1140153693';<br />
-$timezone  = 'UM8';<br />
-$daylight_saving = TRUE;<br />
-<br />
-echo gmt_to_local($timestamp, $timezone, $daylight_saving);</code>
-
-<p><strong>Note:</strong> For a list of timezones see the reference at the bottom of this page.</p>
-
-<h2>mysql_to_unix()</h2>
-
-<p>Takes a MySQL Timestamp as input and returns it as Unix. Example:</p>
-
-<code>$mysql = '20061124092345';<br />
-<br />
-$unix = mysql_to_unix($mysql);</code>
-
-
-<h2>unix_to_human()</h2>
-
-<p>Takes a Unix timestamp as input and returns it in a human readable format with this prototype:</p>
-
-<code>YYYY-MM-DD HH:MM:SS AM/PM</code>
-
-<p>This can be useful if you need to display a date in a form field for submission.</p>
-
-<p>The time can be formatted with or without seconds, and it can be set to European or US format.  If only
-the timestamp is submitted it will return the time without seconds formatted for the U.S. Examples:</p>
-
-<code>$now = time();<br />
-<br />
-echo unix_to_human($now); // U.S. time, no seconds<br />
-<br />
-echo unix_to_human($now, TRUE, 'us'); // U.S. time with seconds<br />
-<br />
-echo unix_to_human($now, TRUE, 'eu'); // Euro time with seconds</code>
-
-
-<h2>human_to_unix()</h2>
-
-<p>The opposite of the above function.  Takes a "human" time as input and returns it as Unix.  This function is
-useful if you accept "human" formatted dates submitted via a form.  Returns FALSE (boolean) if
-the date string passed to it is not formatted as indicated above.  Example:</p>
-
-<code>$now = time();<br />
-<br />
-$human = unix_to_human($now);<br />
-<br />
-$unix = human_to_unix($human);</code>
-
-
-
-<h2>nice_date()</h2>
-
-<p>This function can take a number poorly-formed date formats and convert them into something useful. It also accepts well-formed dates.</p> 
-<p>The function will return a Unix timestamp by default. You can, optionally, pass a format string (the same type as the PHP date function accepts) as the second parameter. Example:</p>
-
-<code>$bad_time = 199605<br />
-<br />
-// Should Produce: 1996-05-01<br />
-$better_time = nice_date($bad_time,'Y-m-d');<br />
-<br />
-$bad_time = 9-11-2001<br />
-// Should Produce: 2001-09-11<br />
-$better_time = nice_date($human,'Y-m-d');</code>
-
-
-
-<h2>timespan()</h2>
-
-<p>Formats a unix timestamp so that is appears similar to this:</p>
-
-<code>1 Year, 10 Months, 2 Weeks, 5 Days, 10 Hours, 16 Minutes</code>
-
-<p>The first parameter must contain a Unix timestamp.  The second parameter must contain a
-timestamp that is greater that the first timestamp.  If the second parameter empty, the current time will be used.  The most common purpose
-for this function is to show how much time has elapsed from some point in time in the past to now.  Example:</p>
-
-<code>$post_date = '1079621429';<br />
-$now = time();<br />
-<br />
-echo timespan($post_date, $now);</code>
-
-<p class="important"><strong>Note:</strong> The text generated by this function is found in the following language file: language/&lt;your_lang&gt;/date_lang.php</p>
-
-
-<h2>days_in_month()</h2>
-
-<p>Returns the number of days in a given month/year. Takes leap years into account.  Example:</p>
-<code>echo days_in_month(06, 2005);</code>
-
-<p>If the second parameter is empty, the current year will be used.</p>
-<h2>timezones()</h2>
-<p> Takes a timezone reference (for a list of valid timezones, see the &quot;Timezone Reference&quot; below) and returns the number of hours offset from UTC.</p>
-<p><code>echo timezones('UM5');</code></p>
-<p>This function is useful when used with timezone_menu(). </p>
-<h2>timezone_menu()</h2>
-<p>Generates a pull-down menu of timezones, like this one:</p>
-
-<form action="#">
-<select name="timezones">
-<option value='UM12'>(UTC - 12:00) Enitwetok, Kwajalien</option>

-<h1>Directory Helper</h1>
-
-<p>The Directory Helper file contains functions that assist in working with directories.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('directory');</code>
-
-<p>The following functions are available:</p>
-
-<h2>directory_map('<var>source directory</var>')</h2>
-
-<p>This function reads the directory path specified in the first parameter
-and builds an array representation of it and all its contained files. Example:</p>
-
-<code>$map = directory_map('./mydirectory/');</code>
-
-<p class="important"><strong>Note:</strong> Paths are almost always relative to your main index.php file.</p>
-
-<p>Sub-folders contained within the directory will be mapped as well.  If you wish to control the recursion depth,
-you can do so using the second parameter (integer). A depth of 1 will only map the top level directory:</p>
-
-<code>$map = directory_map('./mydirectory/', 1);</code>
-
-<p>By default, hidden files will not be included in the returned array.  To override this behavior,
-you may set a third parameter to <var>true</var> (boolean):</p>
-
-<code>$map = directory_map('./mydirectory/', FALSE, TRUE);</code>
-
-<p>Each folder name will be an array index, while its contained files will be numerically indexed.
-Here is an example of a typical array:</p>
-
-<code>Array<br />
-(<br />
-&nbsp;&nbsp;&nbsp;[libraries] => Array<br />
-&nbsp;&nbsp;&nbsp;(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[0] => benchmark.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[1] => config.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[database] => Array<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[0] => active_record.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[1] => binds.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[2] => configuration.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[3] => connecting.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[4] => examples.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[5] => fields.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[6] => index.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[7] => queries.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[2] => email.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[3] => file_uploading.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[4] => image_lib.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[5] => input.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[6] => language.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[7] => loader.html<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[8] => pagination.html<br />

-<h1>File Helper</h1>
-
-<p>The File Helper file contains functions that assist in working with files.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('file');</code>
-
-<p>The following functions are available:</p>
-
-<h2>read_file('<var>path</var>')</h2>
-
-<p>Returns the data contained in the file specified in the path.  Example:</p>
-
-<code>$string = read_file('./path/to/file.php');</code>
-
-<p>The path can be a relative or full server path.  Returns FALSE (boolean) on failure.</p>
-
-<p class="important"><strong>Note:</strong> The path is relative to your main site index.php file, NOT your controller or view files.
-CodeIgniter uses a front controller so paths are always relative to the main site index.</p>
-
-<p>If your server is running an open_basedir restriction this function
-might not work if you are trying to access a file above the calling script.</p>
-
-<h2>write_file('<var>path</var>', <kbd>$data</kbd>)</h2>
-
-<p>Writes data to the file specified in the path.  If the file does not exist the function will create it. Example:</p>
-
-<code>
-$data = 'Some file data';<br />
-<br />
-if ( ! write_file('./path/to/file.php', $data))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp; echo 'Unable to write the file';<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp; echo 'File written!';<br />
-}</code>
-
-<p>You can optionally set the write mode via the third parameter:</p>
-
-<code>write_file('./path/to/file.php', $data, <var>'r+'</var>);</code>
-
-<p>The default mode is <kbd>wb</kbd>.  Please see the <a href="http://php.net/fopen">PHP user guide</a> for mode options.</p>
-
-<p>Note: In order for this function to write data to a file its file permissions must be set such that it is writable (666, 777, etc.).
-If the file does not already exist, the directory containing it must be writable.</p>
-
-<p class="important"><strong>Note:</strong> The path is relative to your main site index.php file, NOT your controller or view files.
-CodeIgniter uses a front controller so paths are always relative to the main site index.</p>
-
-<h2>delete_files('<var>path</var>')</h2>
-
-<p>Deletes ALL files contained in the supplied path.  Example:</p>
-<code>delete_files('./path/to/directory/');</code>
-
-<p>If the second parameter is set to <kbd>true</kbd>, any directories contained within the supplied root path will be deleted as well. Example:</p>
-
-<code>delete_files('./path/to/directory/', TRUE);</code>
-
-<p class="important"><strong>Note:</strong> The files must be writable or owned by the system in order to be deleted.</p>
-
-<h2>get_filenames('<var>path/to/directory/</var>')</h2>
-
-<p>Takes a server path as input and returns an array containing the names of all files contained within it. The file path
-can optionally be added to the file names by setting the second parameter to TRUE.</p>
-
-<h2>get_dir_file_info('<var>path/to/directory/</var>', <kbd>$top_level_only</kbd> = TRUE)</h2>
-
-<p>Reads the specified directory and builds an array containing the filenames, filesize, dates, and permissions.  Sub-folders contained within the specified path are only read if forced
-	by sending the second parameter, <kbd>$top_level_only</kbd> to <samp>FALSE</samp>, as this can be an intensive operation.</p>
-
-<h2>get_file_info('<var>path/to/file</var>', <kbd>$file_information</kbd>)</h2>
-
-<p>Given a file and path, returns the name, path, size, date modified. Second parameter allows you to explicitly declare what information you want returned; options are: name, server_path, size, date, readable, writable, executable, fileperms.  Returns FALSE if the file cannot be found.</p>
-
-<p class="important"><strong>Note:</strong> The &quot;writable&quot; uses the PHP function is_writable() which is known to have issues on the IIS webserver. Consider using fileperms instead, which returns information from PHP's fileperms() function.</p>
-<h2>get_mime_by_extension('<var>file</var>')</h2>
-
-<p>Translates a file extension into a mime type based on config/mimes.php. Returns FALSE if it can't determine the type, or open the mime config file.</p>
-<p>
-<code>$file = &quot;somefile.png&quot;;<br />
-echo $file . ' is has a mime type of ' . get_mime_by_extension($file);</code>
-</p>
-<p class="critical"><strong>Note:</strong> This is not an accurate way of determining file mime types, and is here strictly as a convenience. It should not be  used for security.</p>
-
-<h2>symbolic_permissions(<kbd>$perms</kbd>)</h2>
-
-<p>Takes numeric permissions (such as is returned by <kbd>fileperms()</kbd> and returns standard symbolic notation of file permissions.</p>
-
-<code>echo symbolic_permissions(fileperms('./index.php'));<br />
-<br />
-// -rw-r--r--</code>
-
-<h2>octal_permissions(<kbd>$perms</kbd>)</h2>
-
-<p>Takes numeric permissions (such as is returned by <kbd>fileperms()</kbd> and returns a three character octal notation of file permissions.</p>
-
-<code>echo octal_permissions(fileperms('./index.php'));<br />
-<br />
-// 644</code>

-<h1>Form Helper</h1>
-
-<p>The Form Helper file contains functions that assist in working with forms.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('form');</code>
-
-<p>The following functions are available:</p>
-
-
-
-<h2>form_open()</h2>
-
-<p>Creates an opening form tag with a base URL <strong>built from your config preferences</strong>.  It will optionally let you
-add form attributes and hidden input fields, and will always add the attribute <kbd>accept-charset</kbd> based on the charset value in your config file.</p>
-
-<p>The main benefit of using this tag rather than hard coding your own HTML is that it permits your site to be more portable
-in the event your URLs ever change.</p>
-
-<p>Here's a simple example:</p>
-
-<code>echo form_open('email/send');</code>
-
-<p>The above example would create a form that points to your base URL plus the "email/send" URI segments, like this:</p>
-
-<code>&lt;form method="post" accept-charset="utf-8" action="http:/example.com/index.php/email/send" /></code>
-
-<h4>Adding Attributes</h4>
-
-<p>Attributes can be added by passing an associative array to the second parameter, like this:</p>
-
-<code>
-$attributes = array('class' => 'email', 'id' => 'myform');<br />
-<br />
-echo form_open('email/send', $attributes);</code>
-
-<p>The above example would create a form similar to this:</p>
-
-<code>&lt;form method="post" accept-charset="utf-8" action="http:/example.com/index.php/email/send" &nbsp;class="email" &nbsp;id="myform" /></code>
-
-<h4>Adding Hidden Input Fields</h4>
-
-<p>Hidden fields can be added by passing an associative array to the third parameter, like this:</p>
-
-<code>
-$hidden = array('username' => 'Joe', 'member_id' => '234');<br />
-<br />
-echo form_open('email/send', '', $hidden);</code>
-
-<p>The above example would create a form similar to this:</p>
-
-<code>&lt;form method="post" accept-charset="utf-8" action="http:/example.com/index.php/email/send"><br />
-&lt;input type="hidden" name="username" value="Joe" /><br />
-&lt;input type="hidden" name="member_id" value="234" /></code>
-
-
-<h2>form_open_multipart()</h2>
-
-<p>This function is absolutely identical to the <dfn>form_open()</dfn> tag above except that it adds a multipart attribute,
-which is necessary if you would like to use the form to upload files with.</p>
-
-<h2>form_hidden()</h2>
-
-<p>Lets you generate hidden input fields.  You can either submit a name/value string to create one field:</p>
-
-<code>form_hidden('username', 'johndoe');<br />
-<br />
-// Would produce:<br /><br />
-&lt;input type="hidden" name="username" value="johndoe" /></code>
-
-<p>Or you can submit an associative array to create multiple fields:</p>
-
-<code>$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;=> 'John Doe',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'email' => 'john@example.com',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'url'&nbsp;&nbsp;&nbsp;=> 'http://example.com'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo form_hidden($data);<br />
-<br />
-// Would produce:<br /><br />
-&lt;input type="hidden" name="name" value="John Doe" /><br />
-&lt;input type="hidden" name="email" value="john@example.com" /><br />
-&lt;input type="hidden" name="url" value="http://example.com" /></code>
-
-
-
-
-<h2>form_input()</h2>
-
-<p>Lets you generate a standard text input field.  You can minimally pass the field name and value in the first
-and second parameter:</p>
-
-<code>echo form_input('username', 'johndoe');</code>
-
-<p>Or you can pass an associative array containing any data you wish your form to contain:</p>
-
-<code>$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'username',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'username',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'value'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'johndoe',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'maxlength'&nbsp;&nbsp;&nbsp;=> '100',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'size'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '50',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'style'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'width:50%',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo form_input($data);<br />
-<br />
-// Would produce:<br /><br />
-&lt;input type="text" name="username" id="username" value="johndoe" maxlength="100" size="50" style="width:50%" /></code>
-
-<p>If you would like your form to contain some additional data, like Javascript, you can pass it as a string in the
-third parameter:</p>
-
-<code>$js = 'onClick="some_function()"';<br />
-<br />
-echo form_input('username', 'johndoe', $js);</code>
-
-<h2>form_password()</h2>
-
-<p>This function is identical in all respects to the <dfn>form_input()</dfn> function above
-except that is sets it as a "password" type.</p>
-
-<h2>form_upload()</h2>
-
-<p>This function is identical in all respects to the <dfn>form_input()</dfn> function above
-except that is sets it as a "file" type, allowing it to be used to upload files.</p>
-
-<h2>form_textarea()</h2>
-
-<p>This function is identical in all respects to the <dfn>form_input()</dfn> function above
-except that it generates a "textarea" type. Note: Instead of the "maxlength" and "size" attributes in the above
-example, you will instead specify "rows" and "cols".</p>
-
-
-<h2>form_dropdown()</h2>
-
-<p>Lets you create a standard drop-down field.  The first parameter will contain the name of the field,
-the second parameter will contain an associative array of options, and the third parameter will contain the
-value you wish to be selected.  You can also pass an array of multiple items through the third parameter, and CodeIgniter will create a multiple select for you. Example:</p>
-
-<code>$options = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'small'&nbsp;&nbsp;=> 'Small Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'med'&nbsp;&nbsp;&nbsp;&nbsp;=> 'Medium Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'large'&nbsp;&nbsp; => 'Large Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'xlarge' => 'Extra Large Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$shirts_on_sale = array('small', 'large');<br />
-<br />
-echo form_dropdown('shirts', $options, 'large');<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;select name=&quot;shirts&quot;&gt;<br />
-&lt;option value=&quot;small&quot;&gt;Small Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;med&quot;&gt;Medium  Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;large&quot; selected=&quot;selected&quot;&gt;Large Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;xlarge&quot;&gt;Extra Large Shirt&lt;/option&gt;<br />
-&lt;/select&gt;<br />
-<br />
-echo form_dropdown('shirts', $options, $shirts_on_sale);<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;select name=&quot;shirts&quot; multiple=&quot;multiple&quot;&gt;<br />
-&lt;option value=&quot;small&quot; selected=&quot;selected&quot;&gt;Small Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;med&quot;&gt;Medium  Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;large&quot; selected=&quot;selected&quot;&gt;Large Shirt&lt;/option&gt;<br />
-&lt;option value=&quot;xlarge&quot;&gt;Extra Large Shirt&lt;/option&gt;<br />
-&lt;/select&gt;</code>
-
-
-<p>If you would like the opening &lt;select> to contain additional data, like an <kbd>id</kbd> attribute or JavaScript, you can pass it as a string in the
-fourth parameter:</p>
-
-<code>$js = 'id="shirts" onChange="some_function();"';<br />
-<br />
-echo form_dropdown('shirts', $options, 'large', $js);</code>
-
-<p>If the array passed as $options is a multidimensional array, form_dropdown() will produce an &lt;optgroup&gt; with the array key as the label.</p>
-
-<h2>form_multiselect()</h2>
-
-<p>Lets you create a standard multiselect field.  The first parameter will contain the name of the field,
-the second parameter will contain an associative array of options, and the third parameter will contain the
-value or values you wish to be selected.  The parameter usage is identical to using <kbd>form_dropdown()</kbd> above,
-except of course that the name of the field will need to use POST array syntax, e.g. <samp>foo[]</samp>.</p>
-
-
-<h2>form_fieldset()</h2>
-
-<p>Lets you generate fieldset/legend fields.</p>
-<code>echo form_fieldset('Address Information');<br />
-echo &quot;&lt;p&gt;fieldset content here&lt;/p&gt;\n&quot;;<br />
-echo form_fieldset_close();
-<br />
-<br />
-// Produces<br />
-&lt;fieldset&gt;
-<br />
-&lt;legend&gt;Address Information&lt;/legend&gt;
-<br />
-&lt;p&gt;form content here&lt;/p&gt;
-<br />
-&lt;/fieldset&gt;</code>
-<p>Similar to other functions, you can submit an associative array in the second parameter if you prefer to set additional attributes. </p>
-<p><code>$attributes = array('id' =&gt; 'address_info', 'class' =&gt; 'address_info');<br />
-    echo form_fieldset('Address Information', $attributes);<br />
-echo &quot;&lt;p&gt;fieldset content here&lt;/p&gt;\n&quot;;<br />
-echo form_fieldset_close(); <br />
-<br />
-// Produces<br />
-&lt;fieldset id=&quot;address_info&quot; class=&quot;address_info&quot;&gt; <br />
-&lt;legend&gt;Address Information&lt;/legend&gt; <br />
-&lt;p&gt;form content here&lt;/p&gt; <br />
-&lt;/fieldset&gt;</code></p>
-<h2>form_fieldset_close()</h2>
-<p>Produces a closing &lt;/fieldset&gt; tag.  The only advantage to using this function is it permits you to pass data to it
-    which will be added below the tag.  For example:</p>
-<code>$string = &quot;&lt;/div&gt;&lt;/div&gt;&quot;;<br />
-<br />
-echo form_fieldset_close($string);<br />
-<br />
-// Would produce:<br />
-&lt;/fieldset&gt;<br />
-&lt;/div&gt;&lt;/div&gt;</code>
-<h2>form_checkbox()</h2>
-<p>Lets you generate a checkbox field. Simple example:</p>
-<code>echo form_checkbox('newsletter', 'accept', TRUE);<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;input type=&quot;checkbox&quot; name=&quot;newsletter&quot; value=&quot;accept&quot; checked=&quot;checked&quot; /&gt;</code>
-<p>The third parameter contains a boolean TRUE/FALSE to determine whether the box should be checked or not.</p>
-<p>Similar to the other form functions in this helper, you can also pass an array of attributes to the function:</p>
-
-<code>$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'newsletter',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'newsletter',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'value'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'accept',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'checked'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> TRUE,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'style'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'margin:10px',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo form_checkbox($data);<br />
-<br />
-// Would produce:<br /><br />
-&lt;input type="checkbox" name="newsletter" id="newsletter" value="accept" checked="checked" style="margin:10px" /></code>
-
-<p>As with other functions, if you would like the tag to contain  additional data, like JavaScript, you can pass it as a string in the
-fourth parameter:</p>
-
-<code>$js = 'onClick="some_function()"';<br />
-<br />
- echo form_checkbox('newsletter', 'accept', TRUE, $js)</code>
-
-
-<h2>form_radio()</h2>
-<p>This function is identical in all respects to the <dfn>form_checkbox()</dfn> function above except that is sets it as a "radio" type.</p>
-
-
-<h2>form_submit()</h2>
-
-<p>Lets you generate a standard submit button. Simple example:</p>
-<code>echo form_submit('mysubmit', 'Submit Post!');<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;input type=&quot;submit&quot; name=&quot;mysubmit&quot; value=&quot;Submit Post!&quot; /&gt;</code>
-<p>Similar to other functions, you can submit an associative array in the first parameter if you prefer to set your own attributes.
-    The third parameter lets you add extra data to your form, like JavaScript.</p>
-<h2>form_label()</h2>
-<p>Lets you generate a &lt;label&gt;. Simple example:</p>
-<code>echo form_label('What is your Name', 'username');<br />
-<br />
-// Would produce:
-<br />
-&lt;label for=&quot;username&quot;&gt;What is your Name&lt;/label&gt;</code>
-<p>Similar to other functions, you can submit an associative array in the third parameter if you prefer to set additional attributes.    </p>
-<p><code>$attributes = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'class' =&gt; 'mycustomclass',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'style' =&gt; 'color: #000;',<br />
-);<br />
-    echo form_label('What is your Name', 'username', $attributes);<br />
-        <br />
-// Would produce: <br />
-&lt;label for=&quot;username&quot; class=&quot;mycustomclass&quot; style=&quot;color: #000;&quot;&gt;What is your Name&lt;/label&gt;</code></p>
-<h2>form_reset()</h2>
-
-<p>Lets you generate a standard reset button. Use is identical to <dfn>form_submit()</dfn>.</p>
-
-<h2>form_button()</h2>
-
-<p>Lets you generate a standard button element. You can minimally pass the button name and content in the first and second parameter:</p>
-<code>
-echo form_button('name','content');<br />
-<br />
-// Would produce<br />
-&lt;button name="name" type="button"&gt;Content&lt;/button&gt;
-</code>
-
-Or you can pass an associative array containing any data you wish your form to contain:
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'button',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'id' => 'button',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'value' => 'true',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'type' => 'reset',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'content' => 'Reset'<br />
-);<br />
-<br />
-echo form_button($data);<br />
-<br />
-// Would produce:<br />
-&lt;button name="button" id="button" value="true" type="reset"&gt;Reset&lt;/button&gt;
-</code>
-
-If you would like your form to contain some additional data, like JavaScript, you can pass it as a string in the third parameter:
-<code>
-$js = 'onClick="some_function()"';<br /><br />
-echo form_button('mybutton', 'Click Me', $js);
-</code>
-
-
-<h2>form_close()</h2>
-
-<p>Produces a closing &lt;/form> tag.  The only advantage to using this function is it permits you to pass data to it
-which will be added below the tag.  For example:</p>
-
-<code>$string = "&lt;/div>&lt;/div>";<br />
-<br />
-echo form_close($string);<br />
-<br />
-// Would produce:<br />
-<br />
-&lt;/form><br />
-&lt;/div>&lt;/div></code>
-
-
-
-
-
-<h2>form_prep()</h2>
-
-<p>Allows you to safely use HTML and characters such as quotes within form elements without breaking out of the form.  Consider this example:</p>
-
-<code>$string = 'Here is a string containing <strong>"quoted"</strong> text.';<br />
-<br />
-&lt;input type="text" name="myform" value="<var>$string</var>" /></code>
-
-<p>Since the above string contains a set of quotes it will cause the form to break.
-The form_prep function converts HTML so that it can be used safely:</p>
-
-<code>&lt;input type="text" name="myform" value="<var>&lt;?php echo form_prep($string); ?></var>" /></code>
-
-<p class="important"><strong>Note:</strong> If you use any of the form helper functions listed in this page the form
-values will be prepped automatically, so there is no need to call this function. Use it only if you are
-creating your own form elements.</p>
-
-
-<h2>set_value()</h2>
-
-<p>Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function.
-The second (optional) parameter allows you to set a default value for the form. Example:</p>
-
-<code>&lt;input type="text" name="quantity" value="<dfn>&lt;?php echo set_value('quantity', '0'); ?></dfn>" size="50" /></code>
-
-<p>The above form will show "0" when loaded for the first time.</p>
-
-<h2>set_select()</h2>
-
-<p>If you use a <dfn>&lt;select></dfn> menu, this function permits you to display the menu item that was selected.  The first parameter
-must contain the name of the select menu, the second parameter must contain the value of
-each item, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE).</p>
-
-<p>Example:</p>
-
-<code>
-&lt;select name="myselect"><br />
-&lt;option value="one" <dfn>&lt;?php echo  set_select('myselect', 'one', TRUE); ?></dfn> >One&lt;/option><br />
-&lt;option value="two" <dfn>&lt;?php echo  set_select('myselect', 'two'); ?></dfn> >Two&lt;/option><br />
-&lt;option value="three" <dfn>&lt;?php echo  set_select('myselect', 'three'); ?></dfn> >Three&lt;/option><br />
-&lt;/select>
-</code>
-
-
-<h2>set_checkbox()</h2>
-
-<p>Permits you to display a checkbox in the state it was submitted.  The first parameter
-must contain the name of the checkbox, the second parameter must contain its value, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE). Example:</p>
-
-<code>&lt;input type="checkbox" name="mycheck" value="1" <dfn>&lt;?php echo set_checkbox('mycheck', '1'); ?></dfn> /><br />
-&lt;input type="checkbox" name="mycheck" value="2" <dfn>&lt;?php echo set_checkbox('mycheck', '2'); ?></dfn> /></code>
-
-
-<h2>set_radio()</h2>
-
-<p>Permits you to display radio buttons in the state they were submitted. This function is identical to the <strong>set_checkbox()</strong> function above.</p>
-
-<code>&lt;input type="radio" name="myradio" value="1" <dfn>&lt;?php echo  set_radio('myradio', '1', TRUE); ?></dfn> /><br />
-&lt;input type="radio" name="myradio" value="2" <dfn>&lt;?php echo  set_radio('myradio', '2'); ?></dfn> /></code>

-<h1>HTML Helper</h1>
-
-<p>The HTML Helper file contains functions that assist in working with HTML.</p>
-
-<ul>
-	<li><a href="#br">br()</a></li>
-	<li><a href="#heading">heading()</a></li>
-	<li><a href="#img">img()</a></li>
-	<li><a href="#link_tag">link_tag()</a></li>
-	<li><a href="#nbs">nbs()</a></li>

-	<li><a href="#meta">meta()</a></li>
-	<li><a href="#doctype">doctype()</a></li>
-</ul>
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('html');</code>
-
-<p>The following functions are available:</p>
-
-<h2><a name="br"></a>br()</h2>
-<p>Generates line break tags (&lt;br />) based on the number you submit. Example:</p>
-<code>echo br(3);</code>
-<p>The above would produce: &lt;br />&lt;br />&lt;br /></p>
-
-<h2><a name="heading"></a>heading()</h2>
-<p>Lets you create HTML &lt;h1> tags.  The first parameter will contain the data, the
-second the size of the heading.  Example:</p>
-<code>echo heading('Welcome!', 3);</code>
-<p>The above would produce:  &lt;h3>Welcome!&lt;/h3></p>
-
-<p>Additionally, in order to add attributes to the heading tag such as HTML classes, ids or inline styles, a third parameter is available.</p>
-<code>echo heading('Welcome!', 3, 'class="pink"')</code>
-<p>The above code produces: &lt;h3 class="pink">Welcome!<&lt;h3></p>
-
-
-<h2><a name="img"></a>img()</h2>
-<p>Lets you create HTML &lt;img /&gt; tags.  The first parameter  contains the image source. Example:</p>
-<code>echo img('images/picture.jpg');<br />
-// gives &lt;img src=&quot;http://site.com/images/picture.jpg&quot; /&gt;</code>
-<p>There is an optional second parameter that is a TRUE/FALSE value that specifics if the src should have the page specified by $config['index_page'] added to the address it creates. Presumably, this would be if you were using a media controller.</p>
-<p><code>echo img('images/picture.jpg', TRUE);<br />
-// gives &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; alt=&quot;&quot; /&gt;</code></p>
-<p>Additionally, an associative array can be passed to the img() function for complete control over all attributes and values. If an alt attribute is not provided, CodeIgniter will generate an empty string.</p>
-<p><code> $image_properties = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'src' =&gt; 'images/picture.jpg',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'alt' =&gt; 'Me, demonstrating how to eat 4 slices of pizza at one time',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' =&gt; 'post_images',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'width' =&gt; '200',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'height' =&gt; '200',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' =&gt; 'That was quite a night',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'lightbox',<br />
-	);<br />
-	<br />
-	img($image_properties);<br />
-	// &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; alt=&quot;Me, demonstrating how to eat 4 slices of pizza at one time&quot; class=&quot;post_images&quot; width=&quot;200&quot; height=&quot;200&quot; title=&quot;That was quite a night&quot; rel=&quot;lightbox&quot; /&gt;</code></p>
-
-<h2><a name="link_tag"></a>link_tag()</h2>
-<p>Lets you create HTML &lt;link /> tags.  This is useful for stylesheet links, as well as other links. The parameters are href, with optional rel, type, title, media and index_page. index_page is a TRUE/FALSE value that specifics if the href should have the page specified by $config['index_page'] added to the address it creates.<code>
-echo link_tag('css/mystyles.css');<br />
-// gives &lt;link href=&quot;http://site.com/css/mystyles.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; /&gt;</code></p>
-<p>Further examples:</p>
-
-<code>
-	echo link_tag('favicon.ico', 'shortcut icon', 'image/ico');<br />
-	// &lt;link href=&quot;http://site.com/favicon.ico&quot; rel=&quot;shortcut icon&quot; type=&quot;image/ico&quot; /&gt;
-	<br />
-	<br />
-	echo link_tag('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');<br />
-	// &lt;link href=&quot;http://site.com/feed&quot; rel=&quot;alternate&quot; type=&quot;application/rss+xml&quot; title=&quot;My RSS Feed&quot; /&gt; </code>
-<p>Additionally, an associative array can be passed to the link() function for complete control over all attributes and values.</p>
-<p><code>
-	$link = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'href' =&gt; 'css/printer.css',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'stylesheet',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'text/css',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'media' =&gt; 'print'<br />
-	);<br />
-	<br />
-	echo link_tag($link);<br />
-	// &lt;link href=&quot;http://site.com/css/printer.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;print&quot; /&gt;</code></p>
-
-<h2><a name="nbs"></a>nbs()</h2>
-<p>Generates non-breaking spaces (&amp;nbsp;) based on the number you submit. Example:</p>
-<code>echo nbs(3);</code>
-<p>The above would produce: &amp;nbsp;&amp;nbsp;&amp;nbsp;</p>
-
-<h2><a name="ol_and_ul"></a>ol()&nbsp; and&nbsp; ul()</h2>
-
-<p>Permits you to generate ordered or unordered HTML lists from simple or multi-dimensional arrays. Example:</p>
-
-<code>
-$this->load->helper('html');<br />
-<br />
-$list = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'yellow'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$attributes = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo ul($list, $attributes);<br />
-</code>
-
-<p>The above code will produce this:</p>
-
-<code>
-&lt;ul&nbsp;class="boldlist"&nbsp;id="mylist"><br />
-&nbsp;&nbsp;&lt;li>red&lt;/li><br />
-&nbsp;&nbsp;&lt;li>blue&lt;/li><br />
-&nbsp;&nbsp;&lt;li>green&lt;/li><br />
-&nbsp;&nbsp;&lt;li>yellow&lt;/li><br />
-&lt;/ul>
-</code>
-
-<p>Here is a more complex example, using a multi-dimensional array:</p>
-
-<code>
-$this->load->helper('html');<br />
-<br />
-$attributes = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$list = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'colors' => array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'shapes' => array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'round', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'square',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'circles' => array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ellipse', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'oval', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'sphere'<br />

-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />

-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'happy', <br />

-
-
-
-<h2><a name="meta"></a>meta()</h2>
-
-<p>Helps you generate meta tags.  You can pass strings to the function, or simple arrays, or multidimensional ones. Examples:</p>
-
-<code>
-echo meta('description', 'My Great site');<br />
-// Generates:  &lt;meta name="description" content="My Great Site" /><br />
-<br /><br />
-
-echo meta('Content-type', 'text/html; charset=utf-8', 'equiv'); // Note the third parameter.  Can be "equiv" or "name"<br />
-// Generates:  &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" /><br />
-
-<br /><br />
-
-echo meta(array('name' => 'robots', 'content' => 'no-cache'));<br />
-// Generates:  &lt;meta name="robots" content="no-cache" /><br />
-
-<br /><br />
-
-$meta = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'robots', 'content' => 'no-cache'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'description', 'content' => 'My Great Site'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'keywords', 'content' => 'love, passion, intrigue, deception'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'robots', 'content' => 'no-cache'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'Content-type', 'content' => 'text/html; charset=utf-8', 'type' => 'equiv')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo meta($meta);
-<br />
-// Generates:  <br />
-// &lt;meta name="robots" content="no-cache" /><br />
-// &lt;meta name="description" content="My Great Site" /><br />
-// &lt;meta name="keywords" content="love, passion, intrigue, deception" /><br />
-// &lt;meta name="robots" content="no-cache" /><br />
-// &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" />
-</code>
-
-
-<h2><a name="doctype"></a>doctype()</h2>
-
-<p>Helps you generate document type declarations, or DTD's. XHTML 1.0 Strict is used by default, but many doctypes are available.</p>
-
-<code>
-echo doctype();<br />
-// &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt;<br />

-echo doctype('html4-trans');<br />
-// &lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"&gt;
-</code>
-
-<p>The following is a list of doctype choices.  These are configurable, and pulled from <samp>application/config/doctypes.php</samp></p>

-<h1>Smiley Helper</h1>
-
-<p>The Smiley Helper file contains functions that let you manage smileys (emoticons).</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('smiley');</code>
-
-<h2>Overview</h2>
-
-<p>The Smiley helper has a renderer that takes plain text simileys, like <dfn>:-)</dfn> and turns
-them into a image representation, like <img src="../images/smile.gif" width="19" height="19" border="0" alt="smile!" /></p>
-
-<p>It also lets you display a set of smiley images that when clicked will be inserted into a form field.
-For example, if you have a blog that allows user commenting you can show the smileys next to the comment form.
-Your users can click a desired smiley and with the help of some JavaScript it will be placed into the form field.</p>
-
-
-
-<h2>Clickable Smileys Tutorial</h2>
-
-<p>Here is an example demonstrating how you might create a set of clickable smileys next to a form field. This example
-requires that you first download and install the smiley images, then create a controller and the View as described.</p>
-
-<p class="important"><strong>Important:</strong> Before you begin, please <a href="http://codeigniter.com/download_files/smileys.zip">download the smiley images</a> and put them in
-a publicly accessible place on your server.  This helper also assumes you have the smiley replacement array located at
-<dfn>application/config/smileys.php</dfn></p>
-
-
-<h3>The Controller</h3>
-
-<p>In your <dfn>application/controllers/</dfn> folder, create a file called <kbd>smileys.php</kbd> and place the code below in it.</p>
-
-<p><strong>Important:</strong> Change the URL in the <dfn>get_clickable_smileys()</dfn> function below so that it points to
-your <dfn>smiley</dfn> folder.</p>
-
-<p>You'll notice that in addition to the smiley helper we are using the <a href="../libraries/table.html">Table Class</a>.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="25">
-&lt;?php
-
-class Smileys extends CI_Controller {
-
-	function __construct()
-	{
-		parent::__construct();
-	}
-
-	function index()
-	{
-		$this->load->helper('smiley');
-		$this->load->library('table');
-
-		$image_array = get_clickable_smileys('http://example.com/images/smileys/', 'comments');
-
-		$col_array = $this->table->make_columns($image_array, 8);
-
-		$data['smiley_table'] = $this->table->generate($col_array);
-
-		$this->load->view('smiley_view', $data);
-	}
-
-}
-?&gt;
-</textarea>
-
-<p>In your <dfn>application/views/</dfn> folder, create a file called <kbd>smiley_view.php</kbd> and place this code in it:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="20">
-&lt;html>
-&lt;head>
-&lt;title>Smileys&lt;/title>
-
-&lt;?php echo smiley_js(); ?>
-
-&lt;/head>
-&lt;body>
-
-&lt;form name="blog">
-&lt;textarea name="comments" id="comments" cols="40" rows="4">&lt;/textarea>
-&lt;/form>
-
-&lt;p>Click to insert a smiley!&lt;/p>
-
-&lt;?php echo $smiley_table; ?>
-
-&lt;/body>
-&lt;/html>
-</textarea>
-
-
-<p>When you have created the above controller and view, load it by visiting <dfn>http://www.example.com/index.php/smileys/</dfn></p>
-
-
-<h3>Field Aliases</h3>
-
-<p>When making changes to a view it can be inconvenient to have the field id in the controller. To work around this,
-you can give your smiley links a generic name that will be tied to a specific id in your view.</p>
-<code>$image_array = get_smiley_links("http://example.com/images/smileys/", "comment_textarea_alias");</code>
-
-<p>To map the alias to the field id, pass them both into the smiley_js function:</p>
-<code>$image_array = smiley_js("comment_textarea_alias", "comments");</code>
-
-
-<h1>Function Reference</h1>
-
-<h2>get_clickable_smileys()</h2>
-
-<p>Returns an array containing your smiley images wrapped in a clickable link.  You must supply the URL to your smiley folder
-and a field id or field alias.</p>
-
-<code>$image_array = get_smiley_links("http://example.com/images/smileys/", "comment");</code>
-<p class="important">Note: Usage of this function without the second parameter, in combination with js_insert_smiley has been deprecated.</p>
-
-
-<h2>smiley_js()</h2>
-
-<p>Generates the JavaScript that allows the images to be clicked and inserted into a form field.
-If you supplied an alias instead of an id when generating your smiley links, you need to pass the
-alias and corresponding form id into the function.
-This function is designed to be placed into the &lt;head&gt; area of your web page.</p>
-
-<code>&lt;?php echo smiley_js(); ?&gt;</code>
-<p class="important">Note: This function replaces js_insert_smiley, which has been deprecated.</p>
-
-
-<h2>parse_smileys()</h2>
-
-<p>Takes a string of text as input and replaces any contained plain text smileys into the image
-equivalent.  The first parameter must contain your string, the second must contain  the URL to your smiley folder:</p>
-
-<code>
-$str = 'Here are some simileys: :-)  ;-)';
-
-$str = parse_smileys($str, "http://example.com/images/smileys/");
-
-echo $str;
-</code>

-<h1>String Helper</h1>
-
-<p>The String Helper file contains functions that assist in working with strings.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('string');</code>
-
-<p>The following functions are available:</p>
-
-<h2>random_string()</h2>
-
-<p>Generates a random string based on the type and length you specify.  Useful for creating passwords or generating random hashes.</p>
-
-<p>The first parameter specifies the type of string, the second parameter specifies the length.  The following choices are available:</p>
-
- alpha, alunum, numeric, nozero, unique, md5, encrypt and sha1
-<ul>
-	<li><strong>alpha</strong>:&nbsp; A string with lower and uppercase letters only.</li>
-	<li><strong>alnum</strong>:&nbsp; Alpha-numeric string with lower and uppercase characters.</li>
-	<li><strong>numeric</strong>:&nbsp; Numeric string.</li>
-	<li><strong>nozero</strong>:&nbsp; Numeric string with no zeros.</li>
-	<li><strong>unique</strong>:&nbsp; Encrypted with MD5 and uniqid(). Note: The length parameter is not available for this type.
-	Returns a fixed length 32 character string.</li>
-	<li><strong>sha1</strong>:&nbsp; An encrypted random number based on <kbd>do_hash()</kbd> from the <a href="security_helper.html">security helper</a>.</li>
-</ul>
-
-<p>Usage example:</p>
-
-<code>echo random_string('alnum', 16);</code>
-
-
-<h2>increment_string()</h2>
-
-<p>Increments a string by appending a number to it or increasing the number. Useful for creating "copies" or a file or duplicating database content which has unique titles or slugs.</p>
-
-<p>Usage example:</p>
-
-<code>echo increment_string('file', '_'); // "file_1"<br/>
-echo increment_string('file', '-', 2); // "file-2"<br/>
-echo increment_string('file-4'); // "file-5"<br/></code>
-
-
-<h2>alternator()</h2>
-
-<p>Allows two or more items to be alternated between, when cycling through a loop.  Example:</p>
-
-<code>for ($i = 0; $i < 10; $i++)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo alternator('string one', 'string two');<br />
-}<br />
-</code>
-
-<p>You can add as many parameters as you want, and with each iteration of your loop the next item will be returned.</p>
-
-<code>for ($i = 0; $i < 10; $i++)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo alternator('one', 'two', 'three', 'four', 'five');<br />
-}<br />
-</code>
-
-<p><strong>Note:</strong> To use multiple separate calls to this function simply call the function with no arguments to re-initialize.</p>
-
-
-
-<h2>repeater()</h2>
-<p>Generates repeating copies of the data you submit. Example:</p>
-<code>$string = "\n";<br />
-echo repeater($string, 30);</code>
-
-<p>The above would generate 30 newlines.</p>
-<h2>reduce_double_slashes()</h2>
-<p>Converts double slashes in a string to a single slash, except those found in http://. Example: </p>
-<code>$string = &quot;http://example.com//index.php&quot;;<br />
-echo reduce_double_slashes($string); // results in &quot;http://example.com/index.php&quot;</code>
-<h2>trim_slashes()</h2>
-<p>Removes any leading/trailing slashes from a string. Example:<br />
-	<br />
-	<code>$string = &quot;/this/that/theother/&quot;;<br />
-echo trim_slashes($string); // results in this/that/theother</code></p>
-
-
-<h2>reduce_multiples()</h2>
-<p>Reduces multiple instances of a particular character occuring directly after each other. Example:</p>
-<code>
-$string="Fred, Bill,, Joe, Jimmy";<br />
-$string=reduce_multiples($string,","); //results in "Fred, Bill, Joe, Jimmy"
-</code>
-<p>The function accepts the following parameters:
-<code>reduce_multiples(string: text to search in, string: character to reduce, boolean: whether to remove the character from the front and end of the string)</code>
-
-The first parameter contains the string in which you want to reduce the multiplies. The second parameter contains the character you want to have reduced.
-The third parameter is FALSE by default; if set to TRUE it will remove occurences of the character at the beginning and the end of the string. Example:
-
-<code>
-$string=",Fred, Bill,, Joe, Jimmy,";<br />
-$string=reduce_multiples($string, ", ", TRUE); //results in "Fred, Bill, Joe, Jimmy"
-</code>
-</p>
-
-<h2>quotes_to_entities()</h2>
-<p>Converts single and double quotes in a string to the corresponding HTML entities. Example:</p>
-<code>$string="Joe's \"dinner\"";<br />
-$string=quotes_to_entities($string); //results in "Joe&amp;#39;s &amp;quot;dinner&amp;quot;"
-</code>
-
-<h2>strip_quotes()</h2>
-<p>Removes single and double quotes from a string. Example:</p>
-<code>$string="Joe's \"dinner\"";<br />
-$string=strip_quotes($string); //results in "Joes dinner"
-</code>

-<h1>Text Helper</h1>
-
-<p>The Text Helper file contains functions that assist in working with text.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('text');</code>
-
-<p>The following functions are available:</p>
-
-
-<h2>word_limiter()</h2>
-
-<p>Truncates a string to the number of <strong>words</strong> specified.  Example:</p>
-
-<code>
-$string = "Here is a nice text string consisting of eleven words.";<br />
-<br />
-$string = word_limiter($string, 4);<br /><br />
-
-// Returns:  Here is a nice&#8230;
-</code>
-
-<p>The third parameter is an optional suffix added to the string.  By default it adds an ellipsis.</p>
-
-
-<h2>character_limiter()</h2>
-
-<p>Truncates a string to the number of <strong>characters</strong> specified.  It maintains the integrity
-of words so the character count may be slightly more or less then what you specify. Example:</p>
-
-<code>
-$string = "Here is a nice text string consisting of eleven words.";<br />
-<br />
-$string = character_limiter($string, 20);<br /><br />
-
-// Returns:  Here is a nice text string&#8230;
-</code>
-
-<p>The third parameter is an optional suffix added to the string, if undeclared this helper uses an ellipsis.</p>
-
-
-
-<h2>ascii_to_entities()</h2>
-
-<p>Converts ASCII values to character entities, including high ASCII and MS Word characters that can cause problems when used in a web page,
-so that they can be shown consistently regardless of browser settings or stored reliably in a database.
-There is some dependence on your server's supported character sets, so it may not be 100% reliable in all cases, but for the most
-part it should correctly identify characters outside the normal range (like accented characters). Example:</p>
-
-<code>$string = ascii_to_entities($string);</code>
-
-
-<h2>entities_to_ascii()</h2>
-
-<p>This function does the opposite of the previous one; it turns character entities back into ASCII.</p>
-
-<h2>convert_accented_characters()</h2>
-
-<p>Transliterates high ASCII characters to low ASCII equivalents, useful when non-English characters need to be used where only standard ASCII characters are safely used, for instance, in URLs.</p>
-
-<code>$string = convert_accented_characters($string);</code>
-
-<p>This function uses a companion config file <dfn>application/config/foreign_chars.php</dfn> to define the to and from array for transliteration.</p>
-
-<h2>word_censor()</h2>
-
-<p>Enables you to censor words within a text string.  The first parameter will contain the original string.  The
-second will contain an array of words which you disallow.  The third (optional) parameter can contain a replacement value
-for the words.  If not specified they are replaced with pound signs: ####.  Example:</p>
-
-<code>
-$disallowed = array('darn', 'shucks', 'golly', 'phooey');<br />
-<br />
-$string = word_censor($string, $disallowed, 'Beep!');</code>
-
-
-<h2>highlight_code()</h2>
-
-<p>Colorizes a string of code (PHP, HTML, etc.).  Example:</p>
-
-<code>$string = highlight_code($string);</code>
-
-<p>The function uses PHP's highlight_string() function, so the colors used are the ones specified in your php.ini file.</p>
-
-
-<h2>highlight_phrase()</h2>
-
-<p>Will highlight a phrase within a text string.  The first parameter will contain the original string, the second will
-contain the phrase you wish to highlight.  The third and fourth parameters will contain the opening/closing HTML tags
-you would like the phrase wrapped in.  Example:</p>
-
-<code>
-$string = "Here is a nice text string about nothing in particular.";<br />
-<br />
-$string = highlight_phrase($string, "nice text", '&lt;span style="color:#990000">', '&lt;/span>');
-</code>
-
-<p>The above text returns:</p>
-
-<p>Here is a <span style="color:#990000">nice text</span> string about nothing in particular.</p>
-
-
-
-<h2>word_wrap()</h2>
-
-<p>Wraps text at the specified <strong>character</strong> count while maintaining complete words.  Example:</p>
-
-<code>$string = "Here is a simple string of text that will help us demonstrate this function.";<br />
-<br />
-echo word_wrap($string, 25);<br />
-<br />
-// Would produce:<br />
-<br />
-Here is a simple string<br />
-of text that will help<br />
-us demonstrate this<br />
-function</code>
-
-<h2>ellipsize()</h2>
-
-<p>This function will strip tags from a string, split it at a defined maximum length, and insert an ellipsis.</p>
-<p>The first parameter is the string to ellipsize, the second is the number of characters in the final string. The third parameter is where in the string the ellipsis should appear from 0 - 1, left to right.  For example.  a value of 1 will place the ellipsis at the right of the string, .5 in the middle, and 0 at the left.</p>
-<p>An optional forth parameter is the kind of ellipsis.  By default, <samp>&amp;hellip;</samp> will be inserted.</p>
-
-<code>$str = 'this_string_is_entirely_too_long_and_might_break_my_design.jpg';<br />
-<br />
-echo ellipsize($str, 32, .5);</code>
-
-Produces:
-
-<code>this_string_is_e&hellip;ak_my_design.jpg</code>

-<h1>URL Helper</h1>
-
-<p>The URL Helper file contains functions that assist in working with URLs.</p>
-
-
-<h2>Loading this Helper</h2>
-
-<p>This helper is loaded using the following code:</p>
-<code>$this->load->helper('url');</code>
-
-<p>The following functions are available:</p>
-
-<h2>site_url()</h2>
-
-<p>Returns your site URL, as specified in your config file.  The index.php file (or whatever you have set as your
-site <dfn>index_page</dfn> in your config file) will be added to the URL, as will any URI segments you pass to the function, and the <dfn>url_suffix</dfn> as set in your config file.</p>
-
-<p>You are encouraged to use this function any time you need to generate a local URL so that your pages become more portable
-in the event your URL changes.</p>
-
-<p>Segments can be optionally passed to the function as a string or an array.  Here is a string example:</p>
-
-<code>echo site_url("news/local/123");</code>
-
-<p>The above example would return something like: http://example.com/index.php/news/local/123</p>
-
-<p>Here is an example of segments passed as an array:</p>
-
-<code>
-$segments = array('news', 'local', '123');<br />
-<br />
-echo site_url($segments);</code>
-
-
-<h2>base_url()</h2>
-<p>Returns your site base URL, as specified in your config file.  Example:</p>
-<code>echo base_url();</code>
-
-<p>This function returns the same thing as site_url, without the <dfn>index_page</dfn> or <dfn>url_suffix</dfn> being appended.</p>
-
-<p>Also like site_url, you can supply segments as a string or an array.  Here is a string example:</p>
-
-<code>echo base_url("blog/post/123");</code>
-
-<p>The above example would return something like: http://example.com/blog/post/123</p>
-
-<p>This is useful because unlike site_url(), you can supply a string to a file, such as an image or stylesheet.  For example:</p>
-
-<code>echo base_url("images/icons/edit.png");</code>
-
-<p>This would give you something like: http://example.com/images/icons/edit.png</p>
-
-
-<h2>current_url()</h2>
-<p>Returns the full URL (including segments) of the page being currently viewed.</p>
-
-
-<h2>uri_string()</h2>
-<p>Returns the URI segments of any page that contains this function.  For example, if your URL was this:</p>
-<code>http://some-site.com/blog/comments/123</code>
-
-<p>The function would return:</p>
-<code>/blog/comments/123</code>
-
-
-<h2>index_page()</h2>
-<p>Returns your site "index" page, as specified in your config file.  Example:</p>
-<code>echo index_page();</code>
-
-
-
-<h2>anchor()</h2>
-
-<p>Creates a standard HTML anchor link based on your local site URL:</p>
-
-<code>&lt;a href="http://example.com">Click Here&lt;/a></code>
-
-<p>The tag has three optional parameters:</p>
-
-<code>anchor(<var>uri segments</var>, <var>text</var>, <var>attributes</var>)</code>
-
-<p>The first parameter can contain any segments you wish appended to the URL.  As with the <dfn>site_url()</dfn> function above,
-segments can be a string or an array.</p>
-
-<p><strong>Note:</strong>&nbsp; If you are building links that are internal to your application do not include the base URL (http://...).  This
-will be added automatically from the information specified in your config file. Include only the URI segments you wish appended to the URL.</p>
-
-<p>The second segment is the text you would like the link to say.  If you leave it blank, the URL will be used.</p>
-
-<p>The third parameter can contain a list of attributes you would like added to the link.  The attributes can be a simple string or an associative array.</p>
-
-<p>Here are some examples:</p>
-
-<code>echo anchor('news/local/123', 'My News', 'title="News title"');</code>
-
-<p>Would produce: &lt;a href="http://example.com/index.php/news/local/123" title="News title">My News&lt;/a></p>
-
-<code>echo anchor('news/local/123', 'My News', array('title' => 'The best news!'));</code>
-
-<p>Would produce: &lt;a href="http://example.com/index.php/news/local/123" title="The best news!">My News&lt;/a></p>
-
-
-<h2>anchor_popup()</h2>
-
-<p>Nearly identical to the <dfn>anchor()</dfn> function except that it opens the URL in a new window.
-
-You can specify JavaScript window attributes in the third parameter to control how the window is opened. If
-the third parameter is not set it will simply open a new window with your own browser settings.  Here is an example
-with attributes:</p>
-
-<code>
-
-$atts = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'width'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '800',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'height'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '600',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'scrollbars' => 'yes',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'status'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'yes',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'resizable'&nbsp;&nbsp;=> 'yes',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'screenx'&nbsp;&nbsp;&nbsp;&nbsp;=> '0',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'screeny'&nbsp;&nbsp;&nbsp;&nbsp;=> '0'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo anchor_popup('news/local/123', 'Click Me!', $atts);</code>
-
-<p>Note: The above attributes are the function defaults so you only need to set the ones that are different from what you need.
-If you want the function to use all of its defaults simply pass an empty array in the third parameter:</p>
-
-<code>echo anchor_popup('news/local/123', 'Click Me!', array());</code>
-
-
-<h2>mailto()</h2>
-
-<p>Creates a standard HTML email link.  Usage example:</p>
-
-<code>echo mailto('me@my-site.com', 'Click Here to Contact Me');</code>
-
-<p>As with the <dfn>anchor()</dfn> tab above, you can set attributes using the third parameter.</p>
-
-
-<h2>safe_mailto()</h2>
-
-<p>Identical to the above function except it writes an obfuscated version of the mailto tag using ordinal numbers
-written with JavaScript to help prevent the email address from being harvested by spam bots.</p>
-
-
-<h2>auto_link()</h2>
-
-<p>Automatically turns URLs and email addresses contained in a string into links.  Example:</p>
-
-<code>$string = auto_link($string);</code>
-
-<p>The second parameter determines whether URLs and emails are converted or just one or the other.  Default behavior is both
-if the parameter is not specified.  Email links are encoded as safe_mailto() as shown above.</p>
-
-<p>Converts only URLs:</p>
-<code>$string = auto_link($string, 'url');</code>
-
-<p>Converts only Email addresses:</p>
-<code>$string = auto_link($string, 'email');</code>
-
-<p>The third parameter determines whether links are shown in a new window.  The value can be TRUE or FALSE (boolean):</p>
-<code>$string = auto_link($string, 'both', TRUE);</code>
-
-
-<h2>url_title()</h2>
-<p>Takes a string as input and creates a human-friendly URL string. This is useful if, for example, you have a blog
-in which you'd like to use the title of your entries in the URL.  Example:</p>
-
-<code>$title = "What's wrong with CSS?";<br />
-<br />
-$url_title = url_title($title);<br />
-<br />
-// Produces:  Whats-wrong-with-CSS
-</code>
-
-
-<p>The second parameter determines the word delimiter.  By default dashes are used.  Options are:  <dfn>dash</dfn>, or <dfn>underscore</dfn>:</p>
-
-<code>$title = "What's wrong with CSS?";<br />
-<br />
-$url_title = url_title($title, 'underscore');<br />
-<br />
-// Produces:  Whats_wrong_with_CSS
-</code>
-
-<p>The third parameter determines whether or not lowercase characters are forced.  By default they are not.  Options are boolean <dfn>TRUE</dfn>/<dfn>FALSE</dfn>:</p>
-
-<code>$title = "What's wrong with CSS?";<br />
-<br />
-$url_title = url_title($title, 'underscore', TRUE);<br />
-<br />
-// Produces:  whats_wrong_with_css
-</code>
-
-<h3>prep_url()</h3>
-<p>This function will add <kbd>http://</kbd> in the event that a scheme is missing from a URL.  Pass the URL string to the function like this:</p>
-<code>
-$url = "example.com";<br /><br />
-$url = prep_url($url);</code>
-
-
-
-
-<h2>redirect()</h2>
-
-<p>Does a "header redirect" to the URI specified. If you specify the full site URL that link will be build, but for local links simply providing the URI segments
-to the controller you want to direct to will create the link. The function will build the URL based on your config file values.</p>
-
-<p>The optional second parameter allows you to choose between the "location"
-method (default) or the "refresh" method.  Location is faster, but on Windows servers it can sometimes be a problem.  The optional third parameter allows you to send a specific HTTP Response Code - this could be used for example to create 301 redirects for search engine purposes. The default Response Code is 302. The third parameter is <em>only</em> available with 'location' redirects, and not 'refresh'. Examples:</p>
-
-<code>if ($logged_in == FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;redirect('/login/form/', 'refresh');<br />
-}<br />
-<br />
-// with 301 redirect<br />
-redirect('/article/13', 'location', 301);</code>
-
-<p class="important"><strong>Note:</strong> In order for this function to work it must be used before anything is outputted
-to the browser since it utilizes server headers.<br />
-<strong>Note:</strong> For  very fine grained control over headers, you should use the <a href="../libraries/output.html">Output  Library</a>'s set_header() function.</p>

-<h2>Welcome to CodeIgniter</h2>
-
-<p>CodeIgniter is an Application Development Framework - a toolkit - for people who build web sites using PHP.
-Its goal is to enable you to develop projects much faster than you could if you were writing code
-from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and
-logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by
-minimizing the amount of code needed for a given task.</p>
-
-
-<h2>Who is CodeIgniter For?</h2>
-
-<p>CodeIgniter is right for you if:</p>
-
-<ul>
-<li>You want a framework with a small footprint.</li>
-<li>You need exceptional performance.</li>
-<li>You need broad compatibility with standard hosting accounts that run a variety of PHP versions and configurations.</li>
-<li>You want a framework that requires nearly zero configuration.</li>
-<li>You want a framework that does not require you to use the command line.</li>
-<li>You want a framework that does not require you to adhere to restrictive coding rules.</li>
-<li>You are not interested in large-scale monolithic libraries like PEAR.</li>
-<li>You do not want to be forced to learn a templating language (although a template parser is optionally available if you desire one).</li>
-<li>You eschew complexity, favoring simple solutions.</li>
-<li>You need clear, thorough documentation.</li>
-</ul>

-<h1>Installation Instructions</h1>
-
-<p>CodeIgniter is installed in four steps:</p>
-
-<ol>
-<li>Unzip the package.</li>
-<li>Upload the CodeIgniter folders and files to your server.  Normally the index.php file will be at your root.</li>
-<li>Open the <dfn>application/config/config.php</dfn> file with a text editor and set your base URL.  If you intend to use encryption or sessions, set your encryption key.</li>
-<li>If you intend to use a database, open the <dfn>application/config/database.php</dfn> file with a text editor and set your database settings.</li>
-</ol>
-
-<p>If you wish to increase security by hiding the location of your CodeIgniter files you can rename the <dfn>system</dfn> and <dfn>application</dfn> folders
-to something more private.  If you do rename them, you must open your main <kbd>index.php</kbd> file and set the <samp>$system_folder</samp> and <samp>$application_folder</samp>
-variables at the top of the file with the new name you've chosen.</p>
-
-<p>For the best security, both the <dfn>system</dfn> and any <dfn>application</dfn> folders should be placed above web root so that they are not directly accessible via a browser.  By default, .htaccess files are included in each folder to help prevent direct access, but it is best to remove them from public access entirely in case the web server configuration changes or doesn't abide by the .htaccess.</p>
-
-<p>If you would like to keep your views public it is also possible to move the <dfn>views</dfn> folder out of your application folder.</p>
-
-<p>After moving them, open your main <kdb>index.php</kbd> file and set the <samp>$system_folder</samp>, <samp>$application_folder</samp> and <samp>$view_folder</samp> variables, preferably with a full path, e.g. '<dfn>/www/MyUser/system</dfn>'.</p>
-
-<p>
-    One additional measure to take in production environments is to disable
-    PHP error reporting and any other development-only functionality. In CodeIgniter,
-    this can be done by setting the <kbd>ENVIRONMENT</kbd> constant, which is
-    more fully described on the <a href="../general/security.html">security page</a>.
-</p>
-
-<p>That's it!</p>
-
-<p>If you're new to CodeIgniter, please read the <a href="../overview/getting_started.html">Getting Started</a> section of the User Guide to begin learning how
-to build dynamic PHP applications. Enjoy!</p>

-<h1>Troubleshooting</h1>
-
-<p>If you find that no matter what you put in your URL only your default page is loading, it might be that your server
-does not support the PATH_INFO variable needed to serve search-engine friendly URLs.
-
-As a first step, open your <dfn>application/config/config.php</dfn> file and look for the <kbd>URI Protocol</kbd>
-information. It will recommend that you try a couple alternate settings.  If it still doesn't work after you've tried this you'll need
-to force CodeIgniter to add a question mark to your URLs.  To do this open your <kbd>application/config/config.php</kbd> file and change this:</p>
-
-<code>$config['index_page'] = "index.php";</code>
-
-<p>To this:</p>
-
-<code>$config['index_page'] = "index.php?";</code>

-<h1>Upgrading from 1.2 to 1.3</h1>
-
-<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.2.  If you
-have not upgraded to that version please do so first.</p>
-
-
-<p>Before performing an update you should take your site offline by replacing the index.php file
-with a static one.</p>
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace the following directories in your "system" folder with the new versions:</p>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-<ul>
-<li>application/<strong>models</strong>/&nbsp;&nbsp;  (new for 1.3)</li>
-<li>codeigniter&nbsp;&nbsp;   (new for 1.3)</li>
-<li>drivers</li>
-<li>helpers</li>
-<li>init</li>
-<li>language</li>
-<li>libraries</li>
-<li>plugins</li>
-<li>scaffolding</li>
-</ul>
-
-
-<h2>Step 2: Update your error files</h2>
-
-<p>Version 1.3 contains two new error templates located in <dfn>application/errors</dfn>, and for naming consistency the other error templates have
-been renamed.</p>
-
-<p>If you <strong>have not</strong> customized any of the error templates simply
-replace this folder:</p>
-
-<ul>
-<li>application/errors/</li>
-</ul>
-
-<p>If you <strong>have</strong> customized your error templates, rename them as follows:</p>
-
-
-<ul>
-<li>404.php&nbsp;&nbsp; =&nbsp; error_404.php</li>
-<li>error.php&nbsp;&nbsp; =&nbsp; error_general.php</li>
-<li>error_db.php&nbsp;&nbsp; (new)</li>
-<li>error_php.php&nbsp;&nbsp; (new)</li>
-</ul>
-
-
-<h2>Step 3: Update your index.php file</h2>
-
-<p>Please open your main <dfn>index.php</dfn> file (located at your root).  At the very bottom of the file, change this:</p>
-
-<code>require_once BASEPATH.'libraries/Front_controller'.EXT;</code>
-
-<p>To this:</p>
-
-<code>require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;</code>
-
-
-<h2>Step 4: Update your config.php file</h2>
-
-<p>Open your <dfn>application/config/config.php</dfn> file and add these new items:</p>
-
-<pre>
-/*
-|------------------------------------------------
-| URL suffix
-|------------------------------------------------
-|
-| This option allows you to add a suffix to all URLs.
-| For example, if a URL is this:
-|
-| example.com/index.php/products/view/shoes
-|
-| You can optionally add a suffix, like ".html",
-| making the page appear to be of a certain type:
-|
-| example.com/index.php/products/view/shoes.html
-|
-*/
-$config['url_suffix'] = "";
-
-
-/*
-|------------------------------------------------
-| Enable Query Strings
-|------------------------------------------------
-|
-| By default CodeIgniter uses search-engine and
-| human-friendly segment based URLs:
-|
-| example.com/who/what/where/
-|
-| You can optionally enable standard query string
-| based URLs:
-|
-| example.com?who=me&what=something&where=here
-|
-| Options are: TRUE or FALSE (boolean)
-|
-| The two other items let you set the query string "words"
-| that will invoke your controllers and functions:
-| example.com/index.php?c=controller&m=function
-|
-*/
-$config['enable_query_strings'] = FALSE;
-$config['controller_trigger'] = 'c';
-$config['function_trigger'] = 'm';
-</pre>
-
-
-<h2>Step 5: Update your database.php file</h2>
-
-<p>Open your <dfn>application/config/database.php</dfn> file and add these new items:</p>
-
-<pre>
-$db['default']['dbprefix'] = "";
-$db['default']['active_r'] = TRUE;
-</pre>
-
-
-<h2>Step 6: Update your user guide</h2>
-
-<p>Please also replace your local copy of the user guide with the new version.</p>

-allows you greater flexibility in determining which databases you would like used with your models.  If your application is not connecting
-to your database prior to a model being loaded you will have to update your code.  There are several options for connecting,

-| so enable only if you are reasonably sure your visitors can handle it.
-|
-| VERY IMPORTANT:  If you are getting a blank page when compression is enabled it
-| means you are prematurely outputting something to your browser. It could
-| even be a line of whitespace at the end of one of your scripts.  For
-| compression to work, nothing can be sent before the output buffer is called
-| by the output class.  Do not "echo" any values with compression enabled.

-
-<p>And rename it to this:</p>

-<h1>Upgrading from 1.6.3 to 1.7.0</h1>
-
-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
-
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace these files and directories in your "system" folder with the new versions:</p>
-
-<ul>
-
-<li><dfn>system/codeigniter</dfn></li>
-<li><dfn>system/database</dfn></li>
-<li><dfn>system/helpers</dfn></li>
-<li><dfn>system/language</dfn></li>
-<li><dfn>system/libraries</dfn></li>
-</ul>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
-
-
-<h2>Step 2: Update your Session Table</h2>
-
-<p>If you are using the Session class in your application, AND if you are storing session data to a database, you must add a new column named <dfn>user_data</dfn> to your session table.
-Here is an example of what this column might look like for MySQL:</p>
-
-<code>user_data text NOT NULL</code>
-
-<p>To add this column you will run a query similar to this:</p>
-
-<code>ALTER TABLE `ci_sessions` ADD `user_data` text NOT NULL</code>
-
-<p>You'll find more information regarding the new Session functionality in the  <a href="../libraries/sessions.html">Session class</a> page.</p>
-
-
-<h2>Step 3: Update your Validation Syntax</h2>
-
-<p>This is an <strong>optional</strong>, but recommended step, for people currently using the Validation class.  CI 1.7 introduces a new  <a href="../libraries/form_validation.html">Form Validation class</a>, which
-deprecates the old Validation library.  We have left the old one in place so that existing applications that use it will not break, but you are encouraged to
-migrate to the new version as soon as possible.  Please read the user guide carefully as the new library works a little differently, and has several new features.</p>
-
-
-
-<h2>Step 4: Update your user guide</h2>
-<p>Please replace your local copy of the user guide with the new version, including the image files.</p>

-<p>2.0.0 gets rid of the "Plugin" system as their functionality was identical to Helpers, but non-extensible.  You will need to rename your plugin files from <var>filename_pi.php</var> to <var>filename_helper.php</var>, move them to your <kbd>helpers</kbd> folder, and change all instances of:
-
-	<code>$this->load->plugin('foo');</code>
-
-to
-
-	<code>$this->load->helper('foo');</code>
-
-</p>
-
-<h2>Step 4: Update stored encrypted data</h2>
-
-<p class="important"><strong>Note:</strong> If your application does not use the Encryption library, does not store Encrypted data permanently, or is on an environment that does not support Mcrypt, you may skip this step.</p>
-
-<p>The Encryption library has had a number of improvements, some for encryption strength and some for performance, that has an unavoidable consequence of
-	making it no longer possible to decode encrypted data produced by the original version of this library.  To help with the transition, a new method has
-	been added, <kbd>encode_from_legacy()</kbd> that will decode the data with the original algorithm and return a re-encoded string using the improved methods.
-	This will enable you to easily replace stale encrypted data with fresh in your applications, either on the fly or en masse.</p>
-
-<p>Please read <a href="../libraries/encryption.html#legacy">how to use this method</a> in the Encryption library documentation.</p>
-
-<h2>Step 5: Remove loading calls for the compatibility helper.</h2>
-<p>The compatibility helper has been removed from the CodeIgniter core. All methods in it should be natively available in supported PHP versions.</p>
-
-<h2>Step 6: Update Class extension</h2>
-<p>All core classes are now prefixed with <kbd>CI_</kbd>.  Update Models and Controllers to extend CI_Model and CI_Controller, respectively.</p> 
-
-<h2>Step 7: Update Parent Constructor calls</h2>
-<p>All native CodeIgniter classes now use the PHP 5 <kbd>__construct()</kbd> convention. Please update extended libraries to call <kbd>parent::__construct()</kbd>.</p>
-
-<h2>Step 8: Update your user guide</h2>
-<p>Please replace your local copy of the user guide with the new version, including the image files.</p>

-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>

-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace all files and directories in your "system" folder and replace your index.php file. If any modifications were made to your index.php they will need to be made fresh in this new one.</p>
-
-<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>

-<h2>Step 2: Replace config/mimes.php</h2>

-
-
-<h2>Step 3: Check for forms posting to default controller</h2>
-
-<p>
-	The default behavior for <kbd>form_open()</kbd> when called with no parameters used to be to post to the default controller, but it will now just leave an empty action="" meaning the form will submit to the current URL.

-</p>
-
-<code>echo form_open(); //&lt;form action="" method="post" accept-charset="utf-8"></code>
-
-<p>to use either a / or <kbd>base_url()</kbd>:</p>

-
-<p>If you are running a stock <dfn>index.php</dfn> file simply replace your version with the new one.</p>
-
-<p>If your <dfn>index.php</dfn> file has internal modifications, please add your modifications to the new file and use it.</p>
-
-<h2>Step 3: Replace config/user_agents.php</h2>
-
-<p>This config file has been updated to contain more user agent types, please copy it to <kbd>application/config/user_agents.php</kbd>.</p>
-
-<h2>Step 4: Change references of the EXT constant to ".php"</h2>
-<p class="important"><strong>Note:</strong> The EXT Constant has been marked as deprecated, but has not been removed from the application.  You are encouraged to make the changes sooner rather than later.</p>
-
-<h2>Step 5: Remove APPPATH.'third_party' from autoload.php</h2>
-
-<p>Open application/autoload.php, and look for the following:</p>
-
-<code>$autoload['packages'] = array(APPPATH.'third_party');</code>
-
-<p>If you have not chosen to load any additional packages, that line can be changed to:</p>
-<code>$autoload['packages'] = array();</code>
-
-<p>Which should provide for nominal performance gains if not autoloading packages.</p>
-
-<h2>Update Sessions Database Tables</h2>
-
-<p>If you are using database sessions with the CI Session Library, please update your <samp>ci_sessions</samp> database table as follows:</p>
-
-<code>
-	CREATE INDEX last_activity_idx ON ci_sessions(last_activity);
-	ALTER TABLE ci_sessions MODIFY user_agent VARCHAR(120);

-<h1>Upgrading From Beta 1.0 to Beta 1.1</h1>
-
-<p>To upgrade to Beta 1.1 please perform the following steps:</p>
-
-<h2>Step 1: Replace your index file</h2>
-
-<p>Replace your main <kbd>index.php</kbd> file with the new index.php file. Note:  If you have renamed your "system" folder you will need to edit this info in the new file.</p>
-
-<h2>Step 2: Relocate your config folder</h2>
-
-<p>This version of CodeIgniter now permits multiple sets of "applications" to all share a common set of backend files. In order to enable
-each application to have its own configuration values, the <kbd>config</kbd> directory must now reside
-inside of your <dfn>application</dfn> folder, so please move it there.</p>
-
-
-<h2>Step 3: Replace directories</h2>
-
-<p>Replace the following directories with the new versions:</p>
-
-<ul>
-<li>drivers</li>
-<li>helpers</li>
-<li>init</li>
-<li>libraries</li>
-<li>scaffolding</li>
-</ul>
-
-
-<h2>Step 4: Add the calendar language file</h2>
-
-<p>There is a new language file corresponding to the new calendaring class which must be added to your language folder. Add
-the following item to your version: <dfn>language/english/calendar_lang.php</dfn></p>
-
-
-<h2>Step 5: Edit your config file</h2>
-
-<p>The original <kbd>application/config/config.php</kbd> file has a typo in it  Open the file and look for the items related to cookies:</p>
-
-<code>$conf['cookie_prefix']	= "";<br />
-$conf['cookie_domain']	= "";<br />
-$conf['cookie_path']	= "/";</code>
-
-<p>Change the array name from <kbd>$conf</kbd> to <kbd>$config</kbd>, like this:</p>
-
-<code>$config['cookie_prefix']	= "";<br />
-$config['cookie_domain']	= "";<br />
-$config['cookie_path']	= "/";</code>
-
-<p>Lastly, add the following new item to the config file (and edit the option if needed):</p>
-
-<code><br />
-/*<br />
-|------------------------------------------------<br />
-| URI PROTOCOL<br />
-|------------------------------------------------<br />
-|<br />
-| This item determines which server global <br />
-| should be used to retrieve the URI string.  The <br />
-| default setting of "auto" works for most servers.<br />
-| If your links do not seem to work, try one of <br />
-| the other delicious flavors:<br />
-| <br />

-<h1>Benchmarking Class</h1>
-
-<p>CodeIgniter has a Benchmarking class that is always active, enabling the time difference between any
-two marked points to be calculated.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-
-<p>In addition, the benchmark is always started the moment the framework is
-invoked, and ended by the output class right before sending the final view to the browser, enabling a very accurate
-timing of the entire system execution to be shown.</p>
-
-
-<h3>Table of Contents</h3>
-
-<ul>
-<li><a href="#using">Using the Benchmark Class</a></li>
-<li><a href="#profiler">Profiling Your Benchmark Points</a></li>
-<li><a href="#execution">Displaying Total Execution Time</a></li>
-<li><a href="#memory">Displaying Memory Consumption</a></li>
-</ul>
-
-
-
-<a name="using"></a>
-<h2>Using the Benchmark Class</h2>
-
-<p>The Benchmark class can be used within your <a href="../general/controllers.html">controllers</a>,  <a href="../general/views.html">views</a>, or your  <a href="../general/models.html">models</a>.  The process for usage is this:</p>
-
-<ol>
-<li>Mark a start point</li>
-<li>Mark an end point</li>
-<li>Run the "elapsed time" function to view the results</li>
-</ol>
-
-<p>Here's an example using real code:</p>
-
-<code>$this->benchmark->mark('code_start');<br />
-<br />
-// Some code happens here<br />
-<br />
-$this->benchmark->mark('code_end');<br />
-<br />
-echo $this->benchmark->elapsed_time('code_start', 'code_end');</code>
-
-<p class="important"><strong>Note:</strong> The words "code_start" and "code_end" are arbitrary.  They are simply words used to set two markers.  You can
-use any words you want, and you can set multiple sets of markers. Consider this example:</p>
-
-<code>$this->benchmark->mark('dog');<br />
-<br />
-// Some code happens here<br />
-<br />
-$this->benchmark->mark('cat');<br />
-<br />
-// More code happens here<br />
-<br />
-$this->benchmark->mark('bird');<br />
-<br />
-echo $this->benchmark->elapsed_time('dog', 'cat');<br />
-echo $this->benchmark->elapsed_time('cat', 'bird');<br />
-echo $this->benchmark->elapsed_time('dog', 'bird');</code>
-
-
-<a name="profiler"></a>
-<h2>Profiling Your Benchmark Points</h2>
-
-<p>If you want your benchmark data to be available to the
-<a href="../general/profiling.html">Profiler</a> all of your marked points must be set up in pairs, and
-each mark point name must end with <kbd>_start</kbd> and <kbd>_end</kbd>.
-Each pair of points must otherwise be named identically. Example:</p>
-
-<code>
-$this->benchmark->mark('my_mark<kbd>_start</kbd>');<br />
-<br />
-// Some code happens here...<br />
-<br />
-$this->benchmark->mark('my_mark<kbd>_end</kbd>');
-<br /><br />
-
-$this->benchmark->mark('another_mark<kbd>_start</kbd>');<br />
-<br />
-// Some more code happens here...<br />
-<br />
-$this->benchmark->mark('another_mark<kbd>_end</kbd>');
-</code>
-
-<p>Please read the <a href="../general/profiling.html">Profiler page</a> for more information.</p>
-
-
-<a name="execution"></a>
-<h2>Displaying Total Execution Time</h2>
-
-<p>If you would like to display the total elapsed time from the moment CodeIgniter starts to the moment the final output
-is sent to the browser, simply place this in one of your view templates:</p>
-
-<code>&lt;?php echo $this->benchmark->elapsed_time();?&gt;</code>
-
-<p>You'll notice that it's the same function used in the examples above to calculate the time between two point, except you are
-<strong>not</strong> using any parameters.  When the parameters are absent, CodeIgniter does not stop the benchmark until right before the final
-output is sent to the browser.  It doesn't matter where you use the function call, the timer will continue to run until the very end.</p>
-
-<p>An alternate way to show your elapsed time in your view files is to use this pseudo-variable, if you prefer not to use the pure PHP:</p>
-<code>{elapsed_time}</code>
-
-<p class="important"><strong>Note:</strong> If you want to benchmark anything within your controller
-functions you must set your own start/end points.</p>
-
-<a name="memory"></a>
-<h2>Displaying Memory Consumption</h2>
-
-<p>If your PHP installation is configured with --enable-memory-limit, you can display the amount of memory consumed by the entire
-system using the following code in one of your view file:</p>
-
-<code>&lt;?php echo $this->benchmark->memory_usage();?&gt;</code>
-<p>Note: This function can only be used in your view files. The consumption will reflect the total memory used by the entire app.</p>
-
-<p>An alternate way to show your memory usage in your view files is to use this pseudo-variable, if you prefer not to use the pure PHP:</p>
-<code>{memory_usage}</code>

-<h1>Caching Driver</h1>
-
-<p>CodeIgniter features wrappers around some of the most popular forms of fast and dynamic caching.  All but file-based caching require specific server requirements, and a Fatal Exception will be thrown if server requirements are not met.</p>

-</ul>
-
-<h2 id="example_usage">Example Usage</h2>
-
-<p>The following example will load the cache driver, specify <a href="#apc" title="APC">APC</a> as the driver to use, and fall back to file-based caching if APC is not available in the hosting environment.</p>
-
-<code>
-$this->load->driver('cache', array('adapter' => 'apc', 'backup' => 'file'));<br />
-<br />
-if ( ! $foo = $this->cache->get('foo'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo 'Saving to the cache!&lt;br />';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$foo = 'foobarbaz!';<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Save into the cache for 5 minutes<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->cache->save('foo', $foo, 300);<br />
-}<br />
-<br />
-echo $foo;
-</code>
-
-<h1 id="function_reference">Function Reference</h1>
-
-<h2>is_supported(<var>driver</var>['string'])</h2>
-
-<p>This function is automatically called when accessing drivers via <samp>$this->cache->get()</samp>.  However, if the individual drivers are used, make sure to call this function to ensure the driver is supported in the hosting environment.</p>
-
-<code>
-if ($this->cache->apc->is_supported())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if ($data = $this->cache->apc->get('my_cache'))<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// do things.<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}
-</code>
-
-<h2>get(<var>id</var>['string'])</h2>
-
-<p>This function will attempt to fetch an item from the cache store.  If the item does not exist, the function will return <samp>FALSE</samp>.</p>
-<code>$foo = $this->cache->get('my_cached_item');</code>
-
-<h2>save(<var>id</var>['string'], <var>data</var>['mixed'], <var>ttl</var>['int'])</h2>
-
-<p>This function will save an item to the cache store.  If saving fails, the function will return <samp>FALSE</samp>.</p>
-<p>The optional third parameter (Time To Live) defaults to 60 seconds.</p>
-<code>$this->cache->save('cache_item_id', 'data_to_cache');</code>
-
-<h2>delete(<var>id</var>['string'])</h2>
-
-<p>This function will delete a specific item from the cache store.  If item deletion fails, the function will return <samp>FALSE</samp>.</p>
-<code>$this->cache->delete('cache_item_id');</code>
-
-<h2>clean()</h2>
-
-<p>This function will 'clean' the entire cache.  If the deletion of the cache files fails, the function will return <samp>FALSE</samp>.</p>
-
-<code>$this->cache->clean();</code>
-
-<h2>cache_info()</h2>
-
-<p>This function will return information on the entire cache.</p>
-
-<code>var_dump($this->cache->cache_info());</code>
-
-<h2>get_metadata(<var>id</var>['string'])</h2>
-
-<p>This function will return detailed information on a specific item in the cache.</p>
-
-<code>var_dump($this->cache->get_metadata('my_cached_item'));</code>
-
-<h1>Drivers</h1>
-
-<h2 id="apc">Alternative PHP Cache (APC) Caching</h2>
-
-<p>All of the functions listed above can be accessed without passing a specific adapter to the driver loader as follows:</p>
-<code>$this->load->driver('cache');<br />
-	$this->cache->apc->save('foo', 'bar', 10);</code>
-<p>For more information on APC, please see <a href="http://php.net/apc">http://php.net/apc</a></p>
-
-<h2 id="file">File-based Caching</h2>
-
-<p>Unlike caching from the Output Class, the driver file-based caching allows for pieces of view files to be cached.  Use this with care, and make sure to benchmark your application, as a point can come where disk I/O will negate positive gains by caching.</p>
-
-<p>All of the functions listed above can be accessed without passing a specific adapter to the driver loader as follows:</p>
-<code>$this->load->driver('cache');<br />
-	$this->cache->file->save('foo', 'bar', 10);</code>
-
-<h2 id="memcached">Memcached Caching</h2>
-
-<p>Multiple Memcached servers can be specified in the memcached.php configuration file, located in the <samp>application/config/</samp> directory.
-
-<p>All of the functions listed above can be accessed without passing a specific adapter to the driver loader as follows:</p>

-<h1>Calendaring Class</h1>
-
-<p>The Calendar class enables you to dynamically create calendars. Your calendars can be formatted through the use of a calendar
-template, allowing 100% control over every aspect of its design. In addition, you can pass data to your calendar cells.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Calendar class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('calendar');</code>
-<p>Once loaded, the Calendar object will be available using: <dfn>$this->calendar</dfn></p>
-
-
-<h2>Displaying a Calendar</h2>
-
-<p>Here is a very simple example showing how you can display a calendar:</p>
-
-<code>$this->load->library('calendar');<br />
-<br />
-echo $this->calendar->generate();</code>
-
-<p>The above code will generate a calendar for the current month/year based on your server time.
-To show a calendar for a specific month and year you will pass this information to the calendar generating function:</p>
-
-<code>$this->load->library('calendar');<br />
-<br />
-echo $this->calendar->generate(<kbd>2006</kbd>, <kbd>6</kbd>);</code>
-
-<p>The above code will generate a calendar showing the month of June in 2006.  The first parameter specifies the year, the second parameter specifies the month.</p>
-
-<h2>Passing Data to your Calendar Cells</h2>
-
-<p>To add data to your calendar cells involves creating an associative array in which the keys correspond to the days
-you wish to populate and the array value contains the data.  The array is passed to the third parameter of the calendar
-generating function.  Consider this example:</p>
-
-<code>$this->load->library('calendar');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3&nbsp; => 'http://example.com/news/article/2006/03/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7&nbsp; => 'http://example.com/news/article/2006/07/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13 => 'http://example.com/news/article/2006/13/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;26 => 'http://example.com/news/article/2006/26/'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo $this->calendar->generate(<kbd>2006</kbd>, <kbd>6</kbd>, <var>$data</var>);</code>
-
-<p>Using the above example, day numbers 3, 7, 13, and 26 will become links pointing to the URLs you've provided.</p>
-
-<p class="important"><strong>Note:</strong> By default it is assumed that your array will contain links.
-In the section that explains the calendar template below you'll see how you can customize
-how data passed to your cells is handled so you can pass different types of information.</p>
-
-
-<h2>Setting Display Preferences</h2>
-
-<p>There are seven preferences you can set to control various aspects of the calendar.  Preferences are set by passing an
-array of preferences in the second parameter of the loading function. Here is an example:</p>
-
-
-<code>
-$prefs = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'start_day'&nbsp;&nbsp;&nbsp; => 'saturday',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'month_type'&nbsp;&nbsp; => 'long',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'day_type'&nbsp;&nbsp;&nbsp;&nbsp; => 'short'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->load->library('calendar', $prefs);<br />
-<br />
-echo $this->calendar->generate();</code>
-
-<p>The above code would start the calendar on saturday, use the "long" month heading, and the "short" day names.  More information
-regarding preferences below.</p>
-
-
-
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">
-<tr>
-<th>Preference</th>
-<th>Default&nbsp;Value</th>
-<th>Options</th>
-<th>Description</th>
-</tr><tr>
-<td class="td"><strong>template</strong></td><td class="td">None</td><td class="td">None</td><td class="td">A string containing your calendar template. See the template section below.</td>

-<td class="td"><strong>start_day</strong></td><td class="td">sunday</td><td class="td">Any week day (sunday, monday, tuesday, etc.)</td><td class="td">Sets the day of the week the calendar should start on.</td>
-</tr><tr>
-<td class="td"><strong>month_type</strong></td><td class="td">long</td><td class="td">long, short</td><td class="td">Determines what version of the month name to use in the header. long = January, short = Jan.</td>
-</tr><tr>
-<td class="td"><strong>day_type</strong></td><td class="td">abr</td><td class="td">long, short, abr</td><td class="td">Determines what version of the weekday names to use in the column headers. long = Sunday, short = Sun, abr = Su.</td>
-</tr><tr>
-<td class="td"><strong>show_next_prev</strong></td><td class="td">FALSE</td><td class="td">TRUE/FALSE (boolean)</td><td class="td">Determines whether to display links allowing you to toggle to next/previous months. See information on this feature below.</td>
-</tr><tr>
-<td class="td"><strong>next_prev_url</strong></td><td class="td">None</td><td class="td">A URL</td><td class="td">Sets the basepath used in the next/previous calendar links.</td>
-</tr>
-</table>
-
-
-
-<h2>Showing Next/Previous Month Links</h2>
-
-<p>To allow your calendar to dynamically increment/decrement via the next/previous links requires that you set up your calendar
-code similar to this example:</p>
-
-
-<code>$prefs = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'show_next_prev'&nbsp;&nbsp;=> TRUE,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'next_prev_url'&nbsp;&nbsp; => 'http://example.com/index.php/calendar/show/'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this-&gt;load-&gt;library('calendar', $prefs);<br />
-<br />
-echo $this->calendar->generate(<var>$this->uri->segment(3)</var>, <var>$this->uri->segment(4)</var>);</code>
-
-<p>You'll notice a few things about the above example:</p>
-
-<ul>
-<li>You must set the "show_next_prev" to TRUE.</li>
-<li>You must supply the URL to the controller containing your calendar in the "next_prev_url" preference.</li>
-<li>You must supply the "year" and "month" to the calendar generating function via the URI segments where they appear (Note:  The calendar class automatically adds the year/month to the base URL you provide.).</li>
-</ul>
-
-
-
-<h2>Creating a Calendar Template</h2>
-
-<p>By creating a calendar template you have 100% control over the design of your calendar. Each component of your
-calendar will be placed within a pair of pseudo-variables as shown here:</p>
-
-
-<code>
-$prefs['template'] = '<br /><br />
-&nbsp;&nbsp;&nbsp;<dfn>{table_open}</dfn><var>&lt;table border="0" cellpadding="0" cellspacing="0"></var><dfn>{/table_open}</dfn><br />

-<br />
-&nbsp;&nbsp;&nbsp;<dfn>{heading_row_end}</dfn><var>&lt;/tr></var><dfn>{/heading_row_end}</dfn><br />

-<h1>Shopping Cart Class</h1>
-
-<p>The Cart Class permits items to be added to a session that stays active while a user is browsing your site.
-These items can be retrieved and displayed in a standard "shopping cart" format, allowing the user to update the quantity or remove items from the cart.</p>
-
-<p>Please note that the Cart Class ONLY provides the core "cart" functionality. It does not provide shipping, credit card authorization, or other processing components.</p>
-
-
-<h2>Initializing the Shopping Cart Class</h2>
-
-<p><strong>Important:</strong> The Cart class utilizes CodeIgniter's
-<a href="sessions.html">Session Class</a>  to save the cart information to a database, so before using the Cart class you must set up a database table
-as indicated in the <a href="sessions.html">Session Documentation</a> , and set the session preferences in your <kbd>application/config/config.php</kbd> file to utilize a database.</p>
-
-<p>To initialize the Shopping Cart Class in your controller constructor, use the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('cart');</code>
-<p>Once loaded, the Cart object will be available using: <dfn>$this->cart</dfn></p>
-
-<p class="important"><strong>Note:</strong> The Cart Class will load and initialize the Session Class automatically, so unless you are using sessions elsewhere in your application, you do not need to load the Session class.</p>
-
-<h2>Adding an Item to The Cart</h2>
-
-<p>To add an item to the shopping cart, simply pass an array with the product information to the <dfn>$this->cart->insert()</dfn> function, as shown below:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'sku_123ABC',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'qty'&nbsp;&nbsp;&nbsp;&nbsp; => 1,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'price'&nbsp;&nbsp; => 39.95,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp; => 'T-Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'options' => array('Size' => 'L', 'Color' => 'Red')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-
-$this->cart->insert($data);
-
-</code>
-
-<p class="important"><strong>Important:</strong> The first four array indexes above (<dfn>id</dfn>, <dfn>qty</dfn>, <dfn>price</dfn>, and <dfn>name</dfn>) are <strong>required</strong>.
-If you omit any of them the data will not be saved to the cart. The fifth index (<dfn>options</dfn>) is optional.
-It is intended to be used in cases where your product has options associated with it. Use an array for options, as shown above.</p>
-
-<p>The five reserved indexes are:</p>
-
-<ul>
-<li><strong>id</strong> - Each product in your store must have a unique identifier. Typically this will be an "sku" or other such identifier.</li>
-<li><strong>qty</strong> - The quantity being purchased.
-<li><strong>price</strong> - The price of the item.
-<li><strong>name</strong> - The name of the item.
-<li><strong>options</strong> - Any additional attributes that are needed to identify the product. These must be passed via an array.
-</ul>
-
-<p>In addition to the five indexes above, there are two reserved words: <dfn>rowid</dfn> and <dfn>subtotal</dfn>.  These are used internally by the Cart class, so
-please do NOT use those words as index names when inserting data into the cart.</p>
-
-<p>Your array may contain additional data. Anything you include in your array will be stored in the session. However, it is best to standardize your data among all your products in order to make displaying the information in a table easier.</p>
-
-<p>The insert() method will return the $rowid if you successfully insert a single item.</p>
-
-
-<h2>Adding Multiple Items to The Cart</h2>
-
-<p>By using a multi-dimensional array, as shown below, it is possible to add multiple products to the cart in one action. This is useful in cases where you wish to allow people to select from among several items on the same page.</p>
-
-
-<code>
-$data = array(<br />
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'sku_123ABC',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'qty'&nbsp;&nbsp;&nbsp;&nbsp; => 1,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'price'&nbsp;&nbsp; => 39.95,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp; => 'T-Shirt',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'options' => array('Size' => 'L', 'Color' => 'Red')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />

-</code>
-
-<p><strong>What is a Row ID?</strong>&nbsp; The <kbd>row ID</kbd> is a unique identifier that is generated by the cart code when an item is added to the cart.  The reason a
-unique ID is created is so that identical products with different options can be managed by the cart.</p>
-
-<p>For example, let's say someone buys two identical t-shirts (same product ID), but in different sizes. The product ID (and other attributes) will be
-identical for both sizes because it's the same shirt. The only difference will be the size. The cart must therefore have a means of identifying this
-difference so that the two sizes of shirts can be managed independently. It does so by creating a unique "row ID" based on the product ID and any options associated with it.</p>
-
-<p>In nearly all cases, updating the cart will be something the user does via the "view cart" page, so as a developer, it is unlikely that you will ever have to concern yourself
-with the "row ID", other then making sure your "view cart" page contains this information in a hidden form field, and making sure it gets passed to the update
-function when the update form is submitted. Please examine the construction of the "view cart" page above for more information.</p>

-<h1>Config Class</h1>
-
-<p>The Config class provides a means to retrieve configuration preferences.  These preferences can
-come from the default config file (<samp>application/config/config.php</samp>) or from your own custom config files.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-
-<h2>Anatomy of a Config File</h2>
-
-<p>By default, CodeIgniter has one primary config file, located at <samp>application/config/config.php</samp>.  If you open the file using
-your text editor you'll see that config items are stored in an array called <var>$config</var>.</p>
-
-<p>You can add your own config items to
-this file, or if you prefer to keep your configuration items separate (assuming you even need config items),
-simply create your own file and save it in <dfn>config</dfn> folder.</p>
-
-<p><strong>Note:</strong> If you do create your own config files use the same format as the primary one, storing your items in
-an array called  <var>$config</var>. CodeIgniter will intelligently manage these files so there will be no conflict even though
-the array has the same name (assuming an array index is not named the same as another).</p>
-
-<h2>Loading a Config File</h2>
-
-<p><strong>Note:</strong> CodeIgniter automatically loads the primary config file (<samp>application/config/config.php</samp>),
-so you will only need to load a config file if you have created your own.</p>
-
-<p>There are two ways to load a config file:</p>
-
-<ol><li><strong>Manual Loading</strong>
-
-<p>To load one of your custom config files you will use the following function within the <a href="../general/controllers.html">controller</a> that needs it:</p>
-
-<code>$this->config->load('<var>filename</var>');</code>
-
-<p>Where <var>filename</var> is the name of your config file, without the .php file extension.</p>
-
-<p>If you need to load multiple config files normally they will be merged into one master config array.  Name collisions can occur, however, if
-you have identically named array indexes in different config files.  To avoid collisions you can set the second parameter to <kbd>TRUE</kbd>
-and each config file will be stored in an array index corresponding to the name of the config file. Example:</p>
-
-<code>
-// Stored in an array with this prototype:  $this->config['blog_settings'] = $config<br />
-$this->config->load('<var>blog_settings</var>', <kbd>TRUE</kbd>);</code>
-
-<p>Please see the section entitled <dfn>Fetching Config Items</dfn> below to learn how to retrieve config items set this way.</p>
-
-<p>The third parameter allows you to suppress errors in the event that a config file does not exist:</p>
-
-<code>$this->config->load('<var>blog_settings</var>', <dfn>FALSE</dfn>, <kbd>TRUE</kbd>);</code>
-
-</li>
-<li><strong>Auto-loading</strong>
-
-<p>If you find that you need a particular config file globally, you can have it loaded automatically by the system.  To do this,
-open the <strong>autoload.php</strong> file, located at <samp>application/config/autoload.php</samp>, and add your config file as
-indicated in the file.</p>
-</li>
-</ol>
-
-
-<h2>Fetching Config Items</h2>
-
-<p>To retrieve an item from your config file, use the following function:</p>
-
-<code>$this->config->item('<var>item name</var>');</code>
-
-<p>Where <var>item name</var> is the $config array index you want to retrieve. For example, to fetch your language choice you'll do this:</p>
-
-<code>$lang = $this->config->item('language');</code>
-
-<p>The function returns FALSE (boolean) if the item you are trying to fetch does not exist.</p>
-
-<p>If you are using the second parameter of the <kbd>$this->config->load</kbd> function in order to assign your config items to a specific index
-you can retrieve it by specifying the index name in the second parameter of the <kbd>$this->config->item()</kbd> function.  Example:</p>
-
-<code>
-// Loads a config file named blog_settings.php and assigns it to an index named "blog_settings"<br />
-$this->config->load('<var>blog_settings</var>', <kbd>TRUE</kbd>);<br /><br />
-
-// Retrieve a config item named site_name contained within the blog_settings array<br />
-$site_name = $this->config->item('<dfn>site_name</dfn>', '<var>blog_settings</var>');<br /><br />
-
-// An alternate way to specify the same item:<br />
-$blog_config = $this->config->item('<var>blog_settings</var>');<br />
-$site_name = $blog_config['site_name'];</code>
-
-<h2>Setting a Config Item</h2>
-
-<p>If you would like to dynamically set a config item or change an existing one, you can do so using:</p>
-
-<code>$this->config->set_item('<var>item_name</var>', '<var>item_value</var>');</code>
-
-<p>Where <var>item_name</var> is the $config array index you want to change, and <var>item_value</var> is its value.</p>
-
-<a name="environments"></a>
-<h2>Environments</h2>
-
-<p>
-    You may load different configuration files depending on the current environment.
-    The <kbd>ENVIRONMENT</kbd> constant is defined in index.php, and is described
-    in detail in the <a href="../general/environments.html">Handling Environments</a>
-    section.
-</p>
-
-<p>
-    To create an environment-specific configuration file,
-    create or copy a configuration file in application/config/{ENVIRONMENT}/{FILENAME}.php
-</p>
-
-<p>For example, to create a production-only config.php, you would:</p>
-
-<ol>
-    <li>Create the directory application/config/production/</li>
-    <li>Copy your existing config.php into the above directory</li>
-    <li>Edit application/config/production/config.php so it contains your production settings</li>
-</ol>
-
-<p>
-    When you set the <kbd>ENVIRONMENT</kbd> constant to 'production', the settings
-    for your new production-only config.php will be loaded.
-</p>
-
-<p>You can place the following configuration files in environment-specific folders:</p>
-	
-<ul>
-<li>Default CodeIgniter configuration files</li>
-<li>Your own custom configuration files</li>
-</ul>
-
-<p><strong>Note:</strong> CodeIgniter always tries to load the configuration files for the current environment first. If the file does not exist, the global config file (i.e., the one in <samp>application/config/</samp>) is loaded. This means you are not obligated to place <strong>all</strong> of your configuration files in an environment folder &minus; only the files that change per environment.</p>
-
-<h2>Helper Functions</h2>
-
-<p>The config class has the following helper functions:</p>
-
-<h2>$this->config->site_url();</h2>
-<p>This function retrieves the URL to your site, along with the "index" value you've specified in the config file.</p>
-
-<h2>$this->config->base_url();</h2>
-<p>This function retrieves the URL to your site, plus an optional path such as to a stylesheet or image.</p>
-
-<p>The two functions above are normally accessed via the corresponding functions in the <a href="../helpers/url_helper.html">URL Helper.</a></p>    
-    
-<h2>$this->config->system_url();</h2>
-<p>This function retrieves the URL to your <dfn>system folder</dfn>.</p>

-<h1>Email Class</h1>
-
-<p>CodeIgniter's robust Email Class supports the following features:</p>
-
-
-<ul>
-<li>Multiple Protocols: Mail, Sendmail, and SMTP</li>
-<li>Multiple recipients</li>
-<li>CC and BCCs</li>
-<li>HTML or Plaintext email</li>
-<li>Attachments</li>
-<li>Word wrapping</li>
-<li>Priorities</li>
-<li>BCC Batch Mode, enabling large email lists to be broken into small BCC batches.</li>
-<li>Email Debugging tools</li>
-</ul>
-
-
-<h2>Sending Email</h2>
-
-<p>Sending email is not only simple, but you can configure it on the fly or set your preferences in a config file.</p>
-
-<p>Here is a basic example demonstrating how you might send email.  Note:  This example assumes you are sending the email from one of your
-<a href="../general/controllers.html">controllers</a>.</p>
-
-<code>$this->load->library('email');<br />
-<br />
-$this->email->from('your@example.com', 'Your Name');<br />
-$this->email->to('someone@example.com'); <br />
-$this->email->cc('another@another-example.com'); <br />
-$this->email->bcc('them@their-example.com'); <br />
-<br />
-$this->email->subject('Email Test');<br />
-$this->email->message('Testing the email class.');	<br />
-<br />
-$this->email->send();<br />
-<br />
-echo $this->email->print_debugger();</code>
-
-
-
-
-<h2>Setting Email Preferences</h2>
-
-<p>There are 17 different preferences available to tailor how your email messages are sent. You can either set them manually
-as described here, or automatically via preferences stored in your config file, described below:</p>
-
-<p>Preferences are set by passing an array of preference values to the email <dfn>initialize</dfn> function.  Here is an example of how you might set some preferences:</p>
-
-<code>$config['protocol'] = 'sendmail';<br />
-$config['mailpath'] = '/usr/sbin/sendmail';<br />
-$config['charset'] = 'iso-8859-1';<br />
-$config['wordwrap'] = TRUE;<br />
-<br />
-$this->email->initialize($config);</code>
-
-<p><strong>Note:</strong> Most of the preferences have default values that will be used if you do not set them.</p
-
-><h3>Setting Email Preferences in a Config File</h3>
-
-<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
-Simply create a new file called the <var>email.php</var>,  add the <var>$config</var>
-array in that file. Then save the file at <var>config/email.php</var> and it will be used automatically. You
-will NOT need to use the <dfn>$this->email->initialize()</dfn> function if you save your preferences in a config file.</p>
-
-
-
-
-<h2>Email Preferences</h2>
-
-<p>The following is a list of all the preferences that can be set when sending email.</p>

-<h2>Email Function Reference</h2>
-
-<h3>$this->email->from()</h3>
-<p>Sets the email address and name of the person sending the email:</p>
-<code>$this->email->from('<var>you@example.com</var>', '<var>Your Name</var>');</code>
-
-<h3>$this->email->reply_to()</h3>
-<p>Sets the reply-to address.  If the information is not provided the information in the "from" function is used. Example:</p>
-<code>$this->email->reply_to('<var>you@example.com</var>', '<var>Your Name</var>');</code>
-
-
-<h3>$this->email->to()</h3>
-<p>Sets the email address(s) of the recipient(s).  Can be a single email, a comma-delimited list or an array:</p>
-
-<code>$this->email->to('<var>someone@example.com</var>');</code>
-<code>$this->email->to('<var>one@example.com</var>, <var>two@example.com</var>, <var>three@example.com</var>');</code>
-
-<code>$list = array('<var>one@example.com</var>', '<var>two@example.com</var>', '<var>three@example.com</var>');<br />
-<br />
-$this->email->to(<var>$list</var>);</code>
-
-<h3>$this->email->cc()</h3>
-<p>Sets the CC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.</p>
-
-<h3>$this->email->bcc()</h3>
-<p>Sets the BCC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.</p>
-
-
-<h3>$this->email->subject()</h3>
-<p>Sets the email subject:</p>
-<code>$this->email->subject('<var>This is my subject</var>');</code>
-
-<h3>$this->email->message()</h3>
-<p>Sets the email message body:</p>
-<code>$this->email->message('<var>This is my message</var>');</code>
-
-<h3>$this->email->set_alt_message()</h3>
-<p>Sets the alternative email message body:</p>
-<code>$this->email->set_alt_message('<var>This is the alternative message</var>');</code>
-
-<p>This is an optional message string which can be used if you send HTML formatted email.  It lets you specify an alternative
-message with no HTML formatting which is added to the header string for people who do not accept HTML email.
-If you do not set your own message CodeIgniter will extract the message from your HTML email and strip the tags.</p>
-
-
-
-<h3>$this->email->clear()</h3>
-<p>Initializes all the email variables to an empty state.  This function is intended for use if you run the email sending function
-in a loop, permitting the data to be reset between cycles.</p>
-<code>foreach ($list as $name => $address)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->clear();<br /><br />
-
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->to($address);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->from('your@example.com');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->subject('Here is your info '.$name);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->message('Hi '.$name.' Here is the info you requested.');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->email->send();<br />
-}</code>
-
-<p>If you set the parameter to TRUE any attachments will be cleared as well:</p>
-
-<code>$this->email->clear(TRUE);</code>
-
-
-<h3>$this->email->send()</h3>
-<p>The Email sending function. Returns boolean TRUE or FALSE based on success or failure, enabling it to be used
-conditionally:</p>
-
-<code>if ( ! $this->email->send())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;// Generate error<br />
-}</code>
-
-
-<h3>$this->email->attach()</h3>
-<p>Enables you to send an attachment. Put the file path/name in the first parameter. Note: Use a file path, not a URL.
-For multiple attachments use the function multiple times. For example:</p>
-
-<code>$this->email->attach('/path/to/photo1.jpg');<br />
-$this->email->attach('/path/to/photo2.jpg');<br />
-$this->email->attach('/path/to/photo3.jpg');<br />
-<br />
-$this->email->send();</code>
-
-
-<h3>$this->email->print_debugger()</h3>
-<p>Returns a string containing any server messages, the email headers, and the email messsage.  Useful for debugging.</p>
-
-
-<h2>Overriding Word Wrapping</h2>
-
-<p>If you have word wrapping enabled (recommended to comply with RFC 822) and you have a very long link in your email it can
-get wrapped too, causing it to become un-clickable by the person receiving it.  CodeIgniter lets you manually override
-word wrapping within part of your message like this:</p>
-
-<code>The text of your email that<br />
-gets wrapped normally.<br />
-<br />
-<var>{unwrap}</var>http://example.com/a_long_link_that_should_not_be_wrapped.html<var>{/unwrap}</var><br />
-<br />
-More text that will be<br />
-wrapped normally.</code>
-
-<p>Place the item you do not want word-wrapped between: <var>{unwrap}</var> <var>{/unwrap}</var></p>

-<h1>Encryption Class</h1>
-
-<p>The Encryption Class provides two-way data encryption.  It uses a scheme that either compiles
-the message using a randomly hashed bitwise XOR encoding scheme, or is encrypted using
-the Mcrypt library.  If Mcrypt is not available on your server the encoded message will
-still provide a reasonable degree of security for encrypted sessions or other such "light" purposes.
-If Mcrypt is available, you'll be provided with a high degree of security appropriate for storage.</p>
-
-
-<h2>Setting your Key</h2>
-
-<p>A <em>key</em> is a piece of information that controls the cryptographic process and permits an encrypted string to be decoded.
-In fact, the key you chose will provide the <strong>only</strong> means to decode data that was encrypted with that key,
-so not only must you choose the key carefully, you must never change it if you intend use it for persistent data.</p>
-
-<p>It goes without saying that you should guard your key carefully.
-Should someone gain access to your key, the data will be easily decoded.  If your server is not totally under your control
-it's impossible to ensure key security so you may want to think carefully before using it for anything
-that requires high security, like storing credit card numbers.</p>
-
-<p>To take maximum advantage of the encryption algorithm, your key should be 32 characters in length (128 bits).
-The key should be as random a string as you can concoct, with numbers and uppercase and lowercase letters.
-Your key should <strong>not</strong> be a simple text string. In order to be cryptographically secure it
-needs to be as random as possible.</p>
-
-<p>Your key can be either stored in your <dfn>application/config/config.php</dfn>, or you can design your own
-storage mechanism and pass the key dynamically when encoding/decoding.</p>
-
-<p>To save your key to your <dfn>application/config/config.php</dfn>, open the file and set:</p>
-<code>$config['encryption_key'] = "YOUR KEY";</code>
-
-
-<h2>Message Length</h2>
-
-<p>It's important for you to know that the encoded messages the encryption function generates will be approximately 2.6 times longer than the original
-message.  For example, if you encrypt the string "my super secret data", which is 21 characters in length, you'll end up
-with an encoded string that is roughly 55 characters (we say "roughly" because the encoded string length increments in
-64 bit clusters, so it's not exactly linear).  Keep this information in mind when selecting your data storage mechanism.  Cookies,
-for example, can only hold 4K of information.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Encryption class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('encrypt');</code>
-<p>Once loaded, the Encrypt library object will be available using: <dfn>$this->encrypt</dfn></p>
-
-
-<h2>$this->encrypt->encode()</h2>
-
-<p>Performs the data encryption and returns it as a string. Example:</p>
-<code>
-$msg = 'My secret message';<br />
-<br />
-$encrypted_string = $this->encrypt->encode($msg);</code>
-
-<p>You can optionally pass your encryption key via the second parameter if you don't want to use the one in your config file:</p>
-
-<code>
-$msg = 'My secret message';<br />
-$key = 'super-secret-key';<br />
-<br />
-$encrypted_string = $this->encrypt->encode($msg, $key);</code>
-
-
-<h2>$this->encrypt->decode()</h2>
-
-<p>Decrypts an encoded string.  Example:</p>
-
-<code>
-$encrypted_string = 'APANtByIGI1BpVXZTJgcsAG8GZl8pdwwa84';<br />
-<br />
-$plaintext_string = $this->encrypt->decode($encrypted_string);</code>
-
-<p>You can optionally pass your encryption key via the second parameter if you don't want to use the one in your config file:</p>
-
-<code>
-$msg = 'My secret message';<br />
-$key = 'super-secret-key';<br />
-<br />
-$encrypted_string = $this->encrypt->decode($msg, $key);</code>
-
-
-<h2>$this->encrypt->set_cipher();</h2>
-
-<p>Permits you to set an Mcrypt cipher.  By default it uses <samp>MCRYPT_RIJNDAEL_256</samp>.  Example:</p>
-<code>$this->encrypt->set_cipher(MCRYPT_BLOWFISH);</code>
-<p>Please visit php.net for a list of  <a href="http://php.net/mcrypt">available ciphers</a>.</p>
-
-<p>If you'd like to manually test whether your server supports Mcrypt you can use:</p>
-<code>echo ( ! function_exists('mcrypt_encrypt')) ? 'Nope' : 'Yup';</code>
-
-
-<h2>$this->encrypt->set_mode();</h2>
-
-<p>Permits you to set an Mcrypt mode.  By default it uses <samp>MCRYPT_MODE_CBC</samp>.  Example:</p>
-<code>$this->encrypt->set_mode(MCRYPT_MODE_CFB);</code>
-<p>Please visit php.net for a list of  <a href="http://php.net/mcrypt">available modes</a>.</p>
-
-
-<h2>$this->encrypt->sha1();</h2>
-<p>SHA1 encoding function.  Provide a string and it will return a 160 bit one way hash.  Note:  SHA1, just like MD5 is non-decodable. Example:</p>
-<code>$hash = $this->encrypt->sha1('Some string');</code>
-
-<p>Many PHP installations have SHA1 support by default so if all you need is to encode a hash it's simpler to use the native
-function:</p>
-
-<code>$hash = sha1('Some string');</code>
-
-<p>If your server does not support SHA1 you can use the provided function.</p>
-
-<h2 id="legacy">$this->encrypt->encode_from_legacy(<kbd>$orig_data</kbd>, <kbd>$legacy_mode</kbd> = MCRYPT_MODE_ECB, <kbd>$key</kbd> = '');</h2>
-<p>Enables you to re-encode data that was originally encrypted with CodeIgniter 1.x to be compatible with the Encryption library in CodeIgniter 2.x.  It is only
-	necessary to use this method if you have encrypted data stored permanently such as in a file or database and are on a server that supports Mcrypt.  "Light" use encryption
-	such as encrypted session data or transitory encrypted flashdata require no intervention on your part.  However, existing encrypted Sessions will be
-	destroyed since data encrypted prior to 2.x will not be decoded.</p>
-
-<p class="important"><strong>Why only a method to re-encode the data instead of maintaining legacy methods for both encoding and decoding?</strong>  The algorithms in
-	the Encryption library have improved in CodeIgniter 2.x	both for performance and security, and we do not wish to encourage continued use of the older methods.
-	You can of course extend the Encryption library if you wish and replace the new methods with the old and retain seamless compatibility with CodeIgniter 1.x
-	encrypted data, but this a decision that a developer should make cautiously and deliberately, if at all.</p>
-
-<code>$new_data = $this->encrypt->encode_from_legacy(<kbd>$old_encrypted_string</kbd>);</code>
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">
-<tr>
-	<th>Parameter</th>
-	<th>Default</th>
-	<th>Description</th>
-</tr>
-<tr>
-	<td class="td"><strong>$orig_data</strong></td>

-<h1>File Uploading Class</h1>
-
-<p>CodeIgniter's File Uploading Class permits files to be uploaded.  You can set various
-preferences, restricting the type and size of the files.</p>
-
-
-<h2>The Process</h2>
-
-<p>Uploading a file involves the following general process:</p>
-
-
-<ul>
-<li>An upload form is displayed, allowing a user to select a file and upload it.</li>
-<li>When the form is submitted, the file is uploaded to the destination you specify.</li>
-<li>Along the way, the file is validated to make sure it is allowed to be uploaded based on the preferences you set.</li>
-<li>Once uploaded, the user will be shown a success message.</li>
-</ul>
-
-<p>To demonstrate this process here is brief tutorial. Afterward you'll find reference information.</p>
-
-<h2>Creating the Upload Form</h2>
-
-
-
-<p>Using a text editor, create a form called <dfn>upload_form.php</dfn>.  In it, place this code and save it to your <samp>applications/views/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="23">
-&lt;html>
-&lt;head>
-&lt;title>Upload Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;?php echo $error;?>
-
-&lt;?php echo form_open_multipart('upload/do_upload');?>
-
-&lt;input type="file" name="userfile" size="20" />
-
-&lt;br />&lt;br />
-
-&lt;input type="submit" value="upload" />
-
-&lt;/form>
-
-&lt;/body>
-&lt;/html></textarea>
-
-<p>You'll notice we are using a form helper to create the opening form tag.  File uploads require a multipart form, so the helper
-creates the proper syntax for you.  You'll also notice we have an $error variable.  This is so we can show error messages in the event
-the user does something wrong.</p>
-
-
-<h2>The Success Page</h2>
-
-<p>Using a text editor, create a form called <dfn>upload_success.php</dfn>.
-In it, place this code and save it to your <samp>applications/views/</samp> folder:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="20">&lt;html>
-&lt;head>
-&lt;title>Upload Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;h3>Your file was successfully uploaded!&lt;/h3>
-
-&lt;ul>
-&lt;?php foreach ($upload_data as $item => $value):?>
-&lt;li>&lt;?php echo $item;?>: &lt;?php echo $value;?>&lt;/li>
-&lt;?php endforeach; ?>
-&lt;/ul>
-
-&lt;p>&lt;?php echo anchor('upload', 'Upload Another File!'); ?>&lt;/p>
-
-&lt;/body>
-&lt;/html></textarea>
-
-
-<h2>The Controller</h2>
-
-<p>Using a text editor, create a controller called <dfn>upload.php</dfn>.  In it, place this code and save it to your <samp>applications/controllers/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="43">&lt;?php
-
-class Upload extends CI_Controller {
-
-	function __construct()
-	{
-		parent::__construct();
-		$this->load->helper(array('form', 'url'));
-	}
-
-	function index()
-	{
-		$this->load->view('upload_form', array('error' => ' ' ));
-	}
-
-	function do_upload()
-	{
-		$config['upload_path'] = './uploads/';
-		$config['allowed_types'] = 'gif|jpg|png';
-		$config['max_size']	= '100';
-		$config['max_width']  = '1024';
-		$config['max_height']  = '768';
-
-		$this->load->library('upload', $config);
-
-		if ( ! $this->upload->do_upload())
-		{
-			$error = array('error' => $this->upload->display_errors());
-
-			$this->load->view('upload_form', $error);
-		}
-		else
-		{
-			$data = array('upload_data' => $this->upload->data());
-
-			$this->load->view('upload_success', $data);
-		}
-	}
-}
-?&gt;</textarea>
-
-
-<h2>The Upload Folder</h2>
-
-<p>You'll need a destination folder for your uploaded images.  Create a folder at the root of your CodeIgniter installation called
-<dfn>uploads</dfn> and set its file permissions to 777.</p>
-
-
-<h2>Try it!</h2>
-
-<p>To try your form, visit your site using a URL similar to this one:</p>
-
-<code>example.com/index.php/<var>upload</var>/</code>
-
-<p>You should see an upload form. Try uploading an image file (either a jpg, gif, or png). If the path in your
-controller is correct it should work.</p>
-
-
-<p>&nbsp;</p>
-
-<h1>Reference Guide</h1>
-
-
-<h2>Initializing the Upload Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Upload class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('upload');</code>
-<p>Once the Upload class is loaded, the object will be available using: <dfn>$this->upload</dfn></p>
-
-
-<h2>Setting Preferences</h2>
-
-<p>Similar to other libraries, you'll control what is allowed to be upload based on your preferences.  In the controller you
-built above you set the following preferences:</p>
-
-<code>$config['upload_path'] = './uploads/';<br />
-$config['allowed_types'] = 'gif|jpg|png';<br />
-$config['max_size']	= '100';<br />
-$config['max_width']  = '1024';<br />
-$config['max_height']  = '768';<br />
-<br />
-$this->load->library('upload', $config);<br /><br />
-
-// Alternately you can set preferences by calling the initialize function.  Useful if you auto-load the class:<br />
-$this->upload->initialize($config);</code>
-
-<p>The above preferences should be fairly self-explanatory.  Below is a table describing all available preferences.</p>
-
-
-<h2>Preferences</h2>
-
-<p>The following preferences are available.  The default value indicates what will be used if you do not specify that preference.</p>
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">
-<tr>
-<th>Preference</th>
-<th>Default&nbsp;Value</th>

-<td class="td">None</td>
-<td class="td">None</td>
-<td class="td">The path to the folder where the upload should be placed.  The folder must be writable and the path can be absolute or relative.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>allowed_types</strong></td>
-<td class="td">None</td>
-<td class="td">None</td>
-<td class="td">The mime types corresponding to the types of files you allow to be uploaded.  Usually the file extension can be used as the mime type.  Separate multiple types with a pipe.</td>
-</tr>
-
-
-<tr>
-<td class="td"><strong>file_name</strong></td>
-<td class="td">None</td>
-<td class="td">Desired file name</td>
-<td class="td">
-	<p>If set CodeIgniter will rename the uploaded file to this name.  The extension provided in the file name must also be an allowed file type.</p>

-<td class="td">FALSE</td>
-<td class="td">TRUE/FALSE (boolean)</td>
-<td class="td">If set to true, if a file with the same name as the one you are uploading exists, it will be overwritten. If set to false, a number will be appended to the filename if another with the same name exists.</td>
-</tr>
-
-
-<tr>
-<td class="td"><strong>max_size</strong></td>
-<td class="td">0</td>
-<td class="td">None</td>
-<td class="td">The maximum size (in kilobytes) that the file can be.  Set to zero for no limit. Note:  Most PHP installations have their own limit, as specified in the php.ini file.  Usually 2 MB (or 2048 KB) by default.</td>

-<td class="td"><strong>max_width</strong></td>
-<td class="td">0</td>
-<td class="td">None</td>

-
-<tr>
-<td class="td"><strong>encrypt_name</strong></td>
-<td class="td">FALSE</td>
-<td class="td">TRUE/FALSE (boolean)</td>

-
-
-<h2>Setting preferences in a config file</h2>
-
-<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
-Simply create a new file called the <var>upload.php</var>,  add the <var>$config</var>
-array in that file. Then save the file in: <var>config/upload.php</var> and it will be used automatically. You
-will NOT need to use the <dfn>$this->upload->initialize</dfn> function if you save your preferences in a config file.</p>
-
-
-<h2>Function Reference</h2>
-
-<p>The following functions are available</p>
-
-
-<h2>$this->upload->do_upload()</h2>
-
-<p>Performs the upload based on the preferences you've set.  Note:  By default the upload routine expects the file to come from a form field
-called <dfn>userfile</dfn>, and the form must be a "multipart type:</p>
-
-<code>&lt;form method="post" action="some_action" enctype="multipart/form-data" /></code>
-
-<p>If you would like to set your own field name simply pass its value to the <dfn>do_upload</dfn> function:</p>
-
-<code>
-$field_name = "some_field_name";<br />
-$this->upload->do_upload($field_name)</code>
-
-
-<h2>$this->upload->display_errors()</h2>
-
-<p>Retrieves any error messages if the <dfn>do_upload()</dfn> function returned false.  The function does not echo automatically, it
-returns the data so you can assign it however you need.</p>
-
-<h3>Formatting Errors</h3>
-<p>By default the above function wraps any errors within &lt;p> tags.  You can set your own delimiters like this:</p>
-
-<code>$this->upload->display_errors('<var>&lt;p></var>', '<var>&lt;/p></var>');</code>
-
-<h2>$this->upload->data()</h2>
-
-<p>This is a helper function that returns an array containing all of the data related to the file you uploaded.
-Here is the array prototype:</p>
-
-<code>Array<br />
-(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_name]&nbsp;&nbsp;&nbsp;&nbsp;=> mypic.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_type]&nbsp;&nbsp;&nbsp;&nbsp;=> image/jpeg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_path]&nbsp;&nbsp;&nbsp;&nbsp;=> /path/to/your/upload/<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[full_path]&nbsp;&nbsp;&nbsp;&nbsp;=> /path/to/your/upload/jpg.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[raw_name]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> mypic<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[orig_name]&nbsp;&nbsp;&nbsp;&nbsp;=> mypic.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[client_name]&nbsp;&nbsp;=> mypic.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_ext]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> .jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_size]&nbsp;&nbsp;&nbsp;&nbsp;=> 22.2<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[is_image]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 1<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_width]&nbsp;&nbsp;=> 800<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_height] => 600<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_type]&nbsp;&nbsp;&nbsp;=> jpeg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_size_str] => width="800" height="200"<br />

-<h1>Overview</h1>
-
-
-<p>Before explaining CodeIgniter's approach to data validation, let's describe the ideal scenario:</p>
-
-<ol>
-<li>A form is displayed.</li>
-<li>You fill it in and submit it.</li>
-<li>If you submitted something invalid, or perhaps missed a required item, the form is redisplayed containing your data
-along with an error message describing the problem.</li>
-<li>This process continues until you have submitted a valid form.</li>
-</ol>
-
-<p>On the receiving end, the script must:</p>
-
-<ol>
-<li>Check for required data.</li>
-<li>Verify that the data is of the correct type, and meets the correct criteria. For example, if a username is submitted
-it must be validated to contain only permitted characters.  It must be of a minimum length,
-and not exceed a maximum length. The username can't be someone else's existing username, or perhaps even a reserved word. Etc.</li>
-<li>Sanitize the data for security.</li>
-<li>Pre-format the data if needed (Does the data need to be trimmed?  HTML encoded?  Etc.)</li>
-<li>Prep the data for insertion in the database.</li>
-</ol>
-
-
-<p>Although there is nothing terribly complex about the above process, it usually requires a significant
-amount of code, and to display error messages, various control structures are usually placed within the form HTML.
-Form validation, while simple to create, is generally very messy and tedious to implement.</p>
-
-<p>&nbsp;</p>
-
-
-<a name="tutorial"></a>
-<h1>Form Validation Tutorial</h1>
-
-<p>What follows is a "hands on" tutorial for implementing CodeIgniters Form Validation.</p>
-
-
-<p>In order to implement form validation you'll need three things:</p>
-
-<ol>
-<li>A <a href="../general/views.html">View</a> file containing a form.</li>
-<li>A View file containing a "success" message to be displayed upon successful submission.</li>
-<li>A <a href="../general/controllers.html">controller</a> function to receive and process the submitted data.</li>
-</ol>
-
-<p>Let's create those three things, using a member sign-up form as the example.</p>
-
-
-
-<a name="theform"></a>
-
-<h2>The Form</h2>
-
-<p>Using a text editor, create a form called <dfn>myform.php</dfn>.  In it, place this code and save it to your <samp>applications/views/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="30">&lt;html>
-&lt;head>
-&lt;title>My Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;?php echo validation_errors(); ?>
-
-&lt;?php echo form_open('form'); ?>
-
-&lt;h5>Username&lt;/h5>
-&lt;input type="text" name="username" value="" size="50" />
-
-&lt;h5>Password&lt;/h5>
-&lt;input type="text" name="password" value="" size="50" />
-
-&lt;h5>Password Confirm&lt;/h5>
-&lt;input type="text" name="passconf" value="" size="50" />
-
-&lt;h5>Email Address&lt;/h5>
-&lt;input type="text" name="email" value="" size="50" />
-
-&lt;div>&lt;input type="submit" value="Submit" />&lt;/div>
-
-&lt;/form>
-
-&lt;/body>
-&lt;/html>
-</textarea>
-

-
-
-<h2>Try it!</h2>
-
-<p>To try your form, visit your site using a URL similar to this one:</p>
-
-<code>example.com/index.php/<var>form</var>/</code>
-
-<p><dfn>If you submit the form you should simply see the form reload.  That's because you haven't set up any validation
-rules yet.</dfn></p>
-
-<p><strong>Since you haven't told the Form Validation class to validate anything yet, it returns <kbd>FALSE</kbd> (boolean false) by default.  The <samp>run()</samp>
-function only returns <kbd>TRUE</kbd> if it has successfully applied your rules without any of them failing.</strong></p>
-
-
-<h2>Explanation</h2>
-
-<p>You'll notice several things about the above pages:</p>
-
-<p>The <dfn>form</dfn> (myform.php) is a standard web form with a couple exceptions:</p>
-
-<ol>
-<li>It uses a <dfn>form helper</dfn> to create the form opening.
-Technically, this isn't necessary.  You could create the form using standard HTML.  However, the benefit of using the helper
-is that it generates the action URL for you, based on the URL in your config file.  This makes your application more portable in the event your URLs change.</li>
-
-<li>At the top of the form you'll notice the following function call:
-<code>&lt;?php echo validation_errors(); ?&gt;</code>
-
-<p>This function will return any error messages sent back by the validator. If there are no messages it returns an empty string.</p>
-</li>
-</ol>
-
-<p>The <dfn>controller</dfn> (form.php) has one function: <dfn>index()</dfn>. This function initializes the validation class and
-loads the <var>form helper</var> and <var>URL helper</var> used by your view files. It also <samp>runs</samp>
-the validation routine. Based on
-whether the validation was successful it either presents the form or the success page.</p>
-
-
-
-
-<a name="validationrules"></a>
-
-<h2>Setting Validation Rules</h2>
-
-<p>CodeIgniter lets you set as many validation rules as you need for a given field, cascading them in order, and it even lets you prep and pre-process the field data
-at the same time. To set validation rules you will use the <dfn>set_rules()</dfn> function:</p>
-
-<code>$this->form_validation->set_rules();</code>
-
-<p>The above function takes <strong>three</strong> parameters as input:</p>
-
-<ol>
-	<li>The field name - the exact name you've given the form field.</li>
-	<li>A "human" name for this field, which will be inserted into the error message. For example, if your field is named "user" you might give it a human name of "Username". <strong>Note:</strong> If you would like the field name to be stored in a language file, please see <a href="#translatingfn">Translating Field Names</a>.</li>
-	<li>The validation rules for this form field.</li>
-</ol>
-
-
-<p><br />Here is an example. In your <dfn>controller</dfn> (form.php), add this code just below the validation initialization function:</p>
-
-<code>
-$this->form_validation->set_rules('username', 'Username', 'required');<br />
-$this->form_validation->set_rules('password', 'Password', 'required');<br />
-$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');<br />
-$this->form_validation->set_rules('email', 'Email', 'required');<br />
-</code>
-
-<p>Your controller should now look like this:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="28">&lt;?php
-
-class Form extends CI_Controller {
-
-	function index()
-	{
-		$this->load->helper(array('form', 'url'));
-
-		$this->load->library('form_validation');
-
-		$this->form_validation->set_rules('username', 'Username', 'required');
-		$this->form_validation->set_rules('password', 'Password', 'required');
-		$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
-		$this->form_validation->set_rules('email', 'Email', 'required');
-
-		if ($this->form_validation->run() == FALSE)
-		{
-			$this->load->view('myform');
-		}
-		else
-		{
-			$this->load->view('formsuccess');
-		}
-	}
-}
-?></textarea>
-
-<p><dfn>Now submit the form with the fields blank and you should see the error messages.
-If you submit the form with all the fields populated you'll see your success page.</dfn></p>
-
-<p class="important"><strong>Note:</strong> The form fields are not yet being re-populated with the data when
-there is an error.  We'll get to that shortly.</p>

-<h2>Setting Rules Using an Array</h2>
-
-<p>Before moving on it should be noted that the rule setting function can be passed an array if you prefer to set all your rules in one action.
-If you use this approach you must name your array keys as indicated:</p>
-
-<code>
-$config = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'username', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Username', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'password', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Password', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'passconf', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Password Confirmation', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'email', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Email', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->form_validation->set_rules($config);
-</code>
-
-
-
-
-
-
-<a name="cascadingrules"></a>
-<h2>Cascading Rules</h2>
-
-<p>CodeIgniter lets you pipe multiple rules together.  Let's try it. Change your rules in the third parameter of rule setting function, like this:</p>
-
-<code>
-$this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[12]|is_unique[users.username]');<br />
-$this->form_validation->set_rules('password', 'Password', 'required|matches[passconf]');<br />
-$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');<br />
-$this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[users.email]');<br />
-</code>
-
-<p>The above code sets the following rules:</p>
-
-<ol>
-<li>The username field be no shorter than 5 characters and no longer than 12.</li>
-<li>The password field must match the password confirmation field.</li>
-<li>The email field must contain a valid email address.</li>
-</ol>
-
-<p>Give it a try! Submit your form without the proper data and you'll see new error messages that correspond to your new rules.
-There are numerous rules available which you can read about in the validation reference.</p>
-
-
-
-<a name="preppingdata"></a>
-<h2>Prepping Data</h2>
-
-<p>In addition to the validation functions like the ones we used above, you can also prep your data in various ways.
-For example, you can set up rules like this:</p>
-
-<code>
-$this->form_validation->set_rules('username', 'Username', '<kbd>trim</kbd>|required|min_length[5]|max_length[12]|<kbd>xss_clean</kbd>');<br />
-$this->form_validation->set_rules('password', 'Password', '<kbd>trim</kbd>|required|matches[passconf]|<kbd>md5</kbd>');<br />
-$this->form_validation->set_rules('passconf', 'Password Confirmation', '<kbd>trim</kbd>|required');<br />
-$this->form_validation->set_rules('email', 'Email', '<kbd>trim</kbd>|required|valid_email');<br />
-</code>
-
-
-<p>In the above example, we are "trimming" the fields, converting the password to MD5, and running the username through
-the "xss_clean" function, which removes malicious data.</p>
-
-<p><strong>Any native PHP function that accepts one parameter can be used as a rule, like <dfn>htmlspecialchars</dfn>,
-<dfn>trim</dfn>,  <dfn>MD5</dfn>, etc.</strong></p>
-
-<p><strong>Note:</strong> You will generally want to use the prepping functions <strong>after</strong>
-the validation rules so if there is an error, the original data will be shown in the form.</p>
-
-
-
-
-<a name="repopulatingform"></a>
-<h2>Re-populating the form</h2>
-
-<p>Thus far we have only been dealing with errors.  It's time to repopulate the form field with the submitted data. CodeIgniter offers several helper functions
-that permit you to do this. The one you will use most commonly is:</p>
-
-<code>set_value('field name')</code>
-
-
-<p>Open your <dfn>myform.php</dfn> view file and update the <strong>value</strong> in each field using the <dfn>set_value()</dfn> function:</p>
-
-<p><strong>Don't forget to include each field name in the <dfn>set_value()</dfn> functions!</strong></p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="30">
-&lt;html>
-&lt;head>
-&lt;title>My Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;?php echo validation_errors(); ?>
-
-&lt;?php echo form_open('form'); ?>
-
-&lt;h5>Username&lt;/h5>
-&lt;input type="text" name="username" value="&lt;?php echo set_value('username'); ?>" size="50" />
-
-&lt;h5>Password&lt;/h5>
-&lt;input type="text" name="password" value="&lt;?php echo set_value('password'); ?>" size="50" />
-
-&lt;h5>Password Confirm&lt;/h5>
-&lt;input type="text" name="passconf" value="&lt;?php echo set_value('passconf'); ?>" size="50" />
-
-&lt;h5>Email Address&lt;/h5>
-&lt;input type="text" name="email" value="&lt;?php echo set_value('email'); ?>" size="50" />
-
-&lt;div>&lt;input type="submit" value="Submit" />&lt;/div>
-
-&lt;/form>
-
-&lt;/body>
-&lt;/html>
-</textarea>
-
-
-<p><dfn>Now reload your page and submit the form so that it triggers an error.  Your form fields should now be re-populated</dfn></p>
-
-<p class="important"><strong>Note:</strong> The <a href="#functionreference">Function Reference</a> section below contains functions that
-permit you to re-populate &lt;select> menus, radio buttons, and checkboxes.</p>
-
-
-<p><strong>Important Note:</strong> If you use an array as the name of a form field, you must supply it as an array to the function.  Example:</p>
-
-<code>&lt;input type="text" name="<kbd>colors[]</kbd>" value="&lt;?php echo set_value('<kbd>colors[]</kbd>'); ?>" size="50" /></code>

-
-
-<a name="callbacks"></a>
-<h2>Callbacks: Your own Validation Functions</h2>
-
-<p>The validation system supports callbacks to your own validation functions.  This permits you to extend the validation class
-to meet your needs.  For example, if you need to run a database query to see if the user is choosing a unique username, you can
-create a callback function that does that.  Let's create a example of this.</p>
-
-<p>In your controller, change the "username" rule to this:</p>
-
-<code>$this->form_validation->set_rules('username', 'Username', '<kbd>callback_username_check</kbd>');</code>
-
-<p>Then add a new function called <dfn>username_check</dfn> to your controller.  Here's how your controller should now look:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="40">&lt;?php
-
-class Form extends CI_Controller {
-
-	public function index()
-	{
-		$this->load->helper(array('form', 'url'));
-
-		$this->load->library('form_validation');
-
-		$this->form_validation->set_rules('username', 'Username', 'callback_username_check');
-		$this->form_validation->set_rules('password', 'Password', 'required');
-		$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
-		$this->form_validation->set_rules('email', 'Email', 'required|is_unique[users.email]');
-
-		if ($this->form_validation->run() == FALSE)
-		{
-			$this->load->view('myform');
-		}
-		else
-		{
-			$this->load->view('formsuccess');
-		}
-	}
-
-	public function username_check($str)
-	{
-		if ($str == 'test')
-		{
-			$this->form_validation->set_message('username_check', 'The %s field can not be the word "test"');
-			return FALSE;
-		}
-		else
-		{
-			return TRUE;
-		}
-	}
-
-}
-?></textarea>
-
-<p><dfn>Reload your form and submit it with the word "test" as the username.  You can see that the form field data was passed to your
-callback function for you to process.</dfn></p>
-
-<p>To invoke a callback just put the function name in a rule, with "callback_" as the rule <strong>prefix</strong>. If you need
-to receive an extra parameter in your callback function, just add it normally after the function name between square brackets,
-as in: "callback_foo<strong>[bar]</strong>", then it will be passed as the second argument of your callback function.</p>
-
-<p><strong>Note:</strong> You can also process the form data that is passed to your callback and return it.  If your callback returns anything other than a boolean TRUE/FALSE
-it is assumed that the data is your newly processed form data.</p>
-
-<a name="settingerrors"></a>
-<h2>Setting Error Messages</h2>
-
-
-<p>All of the native error messages are located in the following language file:  <dfn>language/english/form_validation_lang.php</dfn></p>
-
-<p>To set your own custom message you can either edit that file, or use the following function:</p>
-
-<code>$this->form_validation->set_message('<var>rule</var>', '<var>Error Message</var>');</code>
-
-<p>Where <var>rule</var> corresponds to the name of a particular rule, and <var>Error Message</var> is the text you would like displayed.</p>
-
-<p>If you include <dfn>%s</dfn> in your error string, it will be replaced with the "human" name you used for your field when you set your rules.</p>
-
-<p>In the "callback" example above, the error message was set by passing the name of the function:</p>
-
-<code>$this->form_validation->set_message('username_check')</code>
-
-<p>You can also override any error message found in the language file.  For example, to change the message for the "required" rule you will do this:</p>
-
-<code>$this->form_validation->set_message('required', 'Your custom message here');</code>
-
-
-
-<a name="translatingfn"></a>
-<h2>Translating Field Names</h2>
-
-<p>If you would like to store the "human" name you passed to the <dfn>set_rules()</dfn> function in a language file, and therefore make the name able to be translated, here's how:</p>
-
-<p>First, prefix your "human" name with <dfn>lang:</dfn>, as in this example:</p>
-
-<code>
-$this->form_validation->set_rules('first_name', '<kbd>lang:</kbd>first_name', 'required');<br />
-</code>
-
-<p>Then, store the name in one of your language file arrays (without the prefix):</p>
-
-<code>$lang['first_name'] = 'First Name';</code>
-
-<p><strong>Note:</strong> If you store your array item in a language file that is not loaded automatically by CI, you'll need to remember to load it in your controller using:</p>
-
-<code>$this->lang->load('file_name');</code>
-
-<p>See the <a href="language.html">Language Class</a> page for more info regarding language files.</p>
-
-
-<a name="errordelimiters"></a>
-<h2>Changing the Error Delimiters</h2>
-
-<p>By default, the Form Validation class adds a paragraph tag (&lt;p&gt;) around each error message shown. You can either change these delimiters globally or
-individually.</p>
-
-<ol>
-
-<li><strong>Changing delimiters Globally</strong>
-
-<p>To globally change the error delimiters, in your controller function, just after loading the Form Validation class, add this:</p>
-
-<code>$this->form_validation->set_error_delimiters('<kbd>&lt;div class="error"></kbd>', '<kbd>&lt;/div></kbd>');</code>
-
-<p>In this example, we've switched to using div tags.</p>
-
-</li>
-
-<li><strong>Changing delimiters Individually</strong>
-
-<p>Each of the two error generating functions shown in this tutorial can be supplied their own delimiters as follows:</p>
-
-<code>&lt;?php echo form_error('field name', '<kbd>&lt;div class="error"></kbd>', '<kbd>&lt;/div></kbd>'); ?></code>
-
-<p>Or:</p>
-
-<code>&lt;?php echo validation_errors('<kbd>&lt;div class="error"></kbd>', '<kbd>&lt;/div></kbd>'); ?></code>
-
-</li>
-</ol>
-
-
-
-
-<a name="individualerrors"></a>
-<h2>Showing Errors Individually</h2>
-
-<p>If you prefer to show an error message next to each form field, rather than as a list, you can use the <dfn>form_error()</dfn> function.</p>
-
-<p>Try it! Change your form so that it looks like this:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="18">
-&lt;h5>Username&lt;/h5>
-&lt;?php echo form_error('username'); ?>
-&lt;input type="text" name="username" value="&lt;?php echo set_value('username'); ?>" size="50" />
-
-&lt;h5>Password&lt;/h5>
-&lt;?php echo form_error('password'); ?>
-&lt;input type="text" name="password" value="&lt;?php echo set_value('password'); ?>" size="50" />
-
-&lt;h5>Password Confirm&lt;/h5>
-&lt;?php echo form_error('passconf'); ?>
-&lt;input type="text" name="passconf" value="&lt;?php echo set_value('passconf'); ?>" size="50" />
-
-&lt;h5>Email Address&lt;/h5>
-&lt;?php echo form_error('email'); ?>
-&lt;input type="text" name="email" value="&lt;?php echo set_value('email'); ?>" size="50" />
-</textarea>
-
-<p>If there are no errors, nothing will be shown.  If there is an error, the message will appear.</p>
-
-<p><strong>Important Note:</strong> If you use an array as the name of a form field, you must supply it as an array to the function.  Example:</p>
-
-<code>&lt;?php echo form_error('<kbd>options[size]</kbd>'); ?><br />
-&lt;input type="text" name="<kbd>options[size]</kbd>" value="&lt;?php echo set_value("<kbd>options[size]</kbd>"); ?>" size="50" />

-<h1>Saving Sets of Validation Rules to a Config File</h1>
-
-<p>A nice feature of the Form Validation class is that it permits you to store all your validation rules for your entire application in a config file.  You
-can organize these rules into "groups".  These groups can either be loaded automatically when a matching controller/function is called, or
-you can manually call each set as needed.</p>
-
-<h3>How to save your rules</h3>
-
-<p>To store your validation rules, simply create a file named <kbd>form_validation.php</kbd> in your <dfn>application/config/</dfn> folder.
-In that file you will place an array named <kbd>$config</kbd> with your rules. As shown earlier, the validation array will have this prototype:</p>
-
-<code>
-$config = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'username', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'label'&nbsp;&nbsp;&nbsp;=> 'Username', <br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rules'&nbsp;&nbsp;&nbsp;=> 'required'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'field'&nbsp;&nbsp;&nbsp;=> 'password', <br />

-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />

-<h3>Creating Sets of Rules</h3>
-
-<p>In order to organize your rules into "sets" requires that you place them into "sub arrays".  Consider the following example, showing two sets of rules.
-We've arbitrarily called these two rules "signup" and "email".  You can name your rules anything you want:</p>
-
-
-<code>$config = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'<kbd>signup</kbd>' => array(<br />

-<h3>Calling a Specific Rule Group</h3>
-
-<p>In order to call a specific group you will pass its name to the <kbd>run()</kbd> function.  For example, to call the <kbd>signup</kbd> rule you will do this:</p>
-
-<code>
-if ($this->form_validation->run('<kbd>signup</kbd>') == FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;$this->load->view('myform');<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;$this->load->view('formsuccess');<br />
-}<br />
-</code>
-
-
-
-<h3>Associating a Controller Function with a Rule Group</h3>
-
-<p>An alternate (and more automatic) method of calling a rule group is to name it according to the controller class/function you intend to use it with.  For example, let's say you
-have a controller named <kbd>Member</kbd> and a function named <kbd>signup</kbd>.  Here's what your class might look like:</p>
-
-<code>
-&lt;?php<br /><br />
-class <kbd>Member</kbd> extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;function <kbd>signup</kbd>()<br />
-&nbsp;&nbsp;&nbsp;{&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->library('form_validation');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if ($this->form_validation->run() == FALSE)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('myform');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;else<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('formsuccess');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;}<br />
-}<br />
-?></code>
-
-<p>In your validation config file, you will name your rule group <kbd>member/signup</kbd>:</p>
-
-
-<code>$config = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'<kbd>member/signup</kbd>' => array(<br />

-<h1>Using Arrays as Field Names</h1>
-
-<p>The Form Validation class supports the use of arrays as field names.  Consider this example:</p>
-
-<code>&lt;input type="text" name="<kbd>options[]</kbd>" value="" size="50" /></code>
-
-<p>If you do use an array as a field name, you must use the EXACT array name in the <a href="#helperreference">Helper Functions</a> that require the field name,
-and as your Validation Rule field name.</p>
-
-<p>For example, to set a rule for the above field you would use:</p>
-
-<code>$this->form_validation->set_rules('<kbd>options[]</kbd>', 'Options', 'required');</code>
-
-<p>Or, to show an error for the above field you would use:</p>
-
-<code>&lt;?php echo form_error('<kbd>options[]</kbd>'); ?></code>
-
-<p>Or to re-populate the field you would use:</p>
-
-<code>&lt;input type="text" name="<kbd>options[]</kbd>" value="<kbd>&lt;?php echo set_value('<kbd>options[]</kbd>'); ?></kbd>" size="50" /></code>
-
-<p>You can use multidimensional arrays as field names as well. For example:</p>
-
-<code>&lt;input type="text" name="<kbd>options[size]</kbd>" value="" size="50" /></code>
-
-<p>Or even:</p>
-
-<code>&lt;input type="text" name="<kbd>sports[nba][basketball]</kbd>" value="" size="50" /></code>
-
-<p>As with our first example, you must use the exact array name in the helper functions:</p>
-
-<code>&lt;?php echo form_error('<kbd>sports[nba][basketball]</kbd>'); ?></code>
-
-<p>If you are using checkboxes (or other fields) that have multiple options, don't forget to leave an empty bracket after each option, so that all selections will be added to the
-POST array:</p>
-
-<code>
-&lt;input type="checkbox" name="<kbd>options[]</kbd>" value="red" /><br />
-&lt;input type="checkbox" name="<kbd>options[]</kbd>" value="blue" /><br />
-&lt;input type="checkbox" name="<kbd>options[]</kbd>" value="green" />
-</code>
-
-<p>Or if you use a multidimensional array:</p>
-
-<code>
-&lt;input type="checkbox" name="<kbd>options[color][]</kbd>" value="red" /><br />
-&lt;input type="checkbox" name="<kbd>options[color][]</kbd>" value="blue" /><br />
-&lt;input type="checkbox" name="<kbd>options[color][]</kbd>" value="green" />
-</code>
-
-<p>When you use a helper function you'll include the bracket as well:</p>
-
-<code>&lt;?php echo form_error('<kbd>options[color][]</kbd>'); ?></code>

-<h1>Function Reference</h1>
-
-<p>The following functions are intended for use in your controller functions.</p>
-
-<h2>$this->form_validation->set_rules();</h2>
-
-<p>Permits you to set validation rules, as described in the tutorial sections above:</p>
-
-<ul>
-<li><a href="#validationrules">Setting Validation Rules</a></li>
-<li><a href="#savingtoconfig">Saving Groups of Validation Rules to a Config File</a></li>
-</ul>
-
-
-<h2>$this->form_validation->run();</h2>
-
-<p>Runs the validation routines.  Returns boolean TRUE on success and FALSE on failure. You can optionally pass the name of the validation
-group via the function, as described in: <a href="#savingtoconfig">Saving Groups of Validation Rules to a Config File</a>.</p>
-
-
-<h2>$this->form_validation->set_message();</h2>
-
-<p>Permits you to set custom error messages.  See <a href="#settingerrors">Setting Error Messages</a> above.</p>
-
-
-<p>&nbsp;</p>
-
-<a name="helperreference"></a>
-<h1>Helper Reference</h1>
-
-<p>The following helper functions are available for use in the view files containing your forms.  Note that these are procedural functions, so they
-<strong>do not</strong> require you to prepend them with $this->form_validation.</p>
-
-<h2>form_error()</h2>
-
-<p>Shows an individual error message associated with the field name supplied to the function.  Example:</p>
-
-<code>&lt;?php echo form_error('username'); ?></code>
-
-<p>The error delimiters can be optionally specified.  See the <a href="#errordelimiters">Changing the Error Delimiters</a> section above.</p>
-
-
-
-<h2>validation_errors()</h2>
-<p>Shows all error messages as a string:  Example:</p>
-
-<code>&lt;?php echo validation_errors(); ?></code>
-
-<p>The error delimiters can be optionally specified.  See the <a href="#errordelimiters">Changing the Error Delimiters</a> section above.</p>
-
-
-
-<h2>set_value()</h2>
-
-<p>Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function.
-The second (optional) parameter allows you to set a default value for the form. Example:</p>
-
-<code>&lt;input type="text" name="quantity" value="<dfn>&lt;?php echo set_value('quantity', '0'); ?></dfn>" size="50" /></code>
-
-<p>The above form will show "0" when loaded for the first time.</p>
-
-<h2>set_select()</h2>
-
-<p>If you use a <dfn>&lt;select></dfn> menu, this function permits you to display the menu item that was selected.  The first parameter
-must contain the name of the select menu, the second parameter must contain the value of
-each item, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE).</p>
-
-<p>Example:</p>
-
-<code>
-&lt;select name="myselect"><br />
-&lt;option value="one" <dfn>&lt;?php echo  set_select('myselect', 'one', TRUE); ?></dfn> >One&lt;/option><br />
-&lt;option value="two" <dfn>&lt;?php echo  set_select('myselect', 'two'); ?></dfn> >Two&lt;/option><br />
-&lt;option value="three" <dfn>&lt;?php echo  set_select('myselect', 'three'); ?></dfn> >Three&lt;/option><br />
-&lt;/select>
-</code>
-
-
-<h2>set_checkbox()</h2>
-
-<p>Permits you to display a checkbox in the state it was submitted.  The first parameter
-must contain the name of the checkbox, the second parameter must contain its value, and the third (optional) parameter lets you set an item as the default (use boolean TRUE/FALSE). Example:</p>
-
-<code>&lt;input type="checkbox" name="mycheck[]" value="1" <dfn>&lt;?php echo set_checkbox('mycheck[]', '1'); ?></dfn> /><br />
-&lt;input type="checkbox" name="mycheck[]" value="2" <dfn>&lt;?php echo set_checkbox('mycheck[]', '2'); ?></dfn> /></code>
-
-
-<h2>set_radio()</h2>
-
-<p>Permits you to display radio buttons in the state they were submitted. This function is identical to the <strong>set_checkbox()</strong> function above.</p>
-
-<code>&lt;input type="radio" name="myradio" value="1" <dfn>&lt;?php echo  set_radio('myradio', '1', TRUE); ?></dfn> /><br />
-&lt;input type="radio" name="myradio" value="2" <dfn>&lt;?php echo  set_radio('myradio', '2'); ?></dfn> /></code>

-<h1>FTP Class</h1>
-
-<p>CodeIgniter's FTP Class permits files to be transfered to a remote server. Remote files can also be moved, renamed,
-and deleted.  The FTP class also includes a "mirroring" function that permits an entire local directory to be recreated remotely via FTP.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; SFTP and SSL FTP protocols are not supported, only standard FTP.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the FTP class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('ftp');</code>
-<p>Once loaded, the FTP object will be available using: <dfn>$this->ftp</dfn></p>
-
-
-<h2>Usage Examples</h2>
-
-<p>In this example a connection is opened to the FTP server, and a local file is read and uploaded in ASCII mode. The
-file permissions are set to 755.  Note: Setting permissions requires PHP 5.</p>
-
-<code>
-$this->load->library('ftp');<br />
-<br />
-$config['hostname'] = 'ftp.example.com';<br />
-$config['username'] = 'your-username';<br />
-$config['password'] = 'your-password';<br />
-$config['debug']	= TRUE;<br />
-<br />
-$this->ftp->connect($config);<br />
-<br />
-$this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775);<br />
-<br />
-$this->ftp->close();
-
-</code>
-
-
-<p>In this example a list of files is retrieved from the server.</p>
-
-<code>
-$this->load->library('ftp');<br />
-<br />
-$config['hostname'] = 'ftp.example.com';<br />
-$config['username'] = 'your-username';<br />
-$config['password'] = 'your-password';<br />
-$config['debug']	= TRUE;<br />
-<br />
-$this->ftp->connect($config);<br />
-<br />
-$list = $this->ftp->list_files('/public_html/');<br />
-<br />
-print_r($list);<br />
-<br />
-$this->ftp->close();
-</code>
-
-<p>In this example a local directory is mirrored on the server.</p>
-
-
-<code>
-$this->load->library('ftp');<br />
-<br />
-$config['hostname'] = 'ftp.example.com';<br />
-$config['username'] = 'your-username';<br />
-$config['password'] = 'your-password';<br />
-$config['debug']	= TRUE;<br />
-<br />
-$this->ftp->connect($config);<br />
-<br />
-$this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/');<br />
-<br />
-$this->ftp->close();
-</code>
-
-
-<h1>Function Reference</h1>
-
-<h2>$this->ftp->connect()</h2>
-
-<p>Connects and logs into to the FTP server. Connection preferences are set by passing an array
-to the function, or you can store them in a config file.</p>
-
-
-<p>Here is an example showing how you set preferences manually:</p>
-
-<code>
-$this->load->library('ftp');<br />
-<br />
-$config['hostname'] = 'ftp.example.com';<br />
-$config['username'] = 'your-username';<br />
-$config['password'] = 'your-password';<br />
-$config['port']&nbsp;&nbsp;&nbsp;&nbsp; = 21;<br />
-$config['passive']&nbsp;&nbsp;= FALSE;<br />
-$config['debug']&nbsp;&nbsp;&nbsp;&nbsp;= TRUE;<br />
-<br />
-$this->ftp->connect($config);<br />
-</code>
-
-<h3>Setting FTP Preferences in a Config File</h3>
-
-<p>If you prefer you can store your FTP preferences in a config file.
-Simply create a new file called the <var>ftp.php</var>,  add the <var>$config</var>
-array in that file. Then save the file at <var>config/ftp.php</var> and it will be used automatically.</p>
-
-<h3>Available connection options:</h3>
-
-
-<ul>
-<li><strong>hostname</strong> - the FTP hostname.  Usually something like:&nbsp; <dfn>ftp.example.com</dfn></li>
-<li><strong>username</strong> - the FTP username.</li>
-<li><strong>password</strong> - the FTP password.</li>
-<li><strong>port</strong> - The port number. Set to <dfn>21</dfn> by default.</li>
-<li><strong>debug</strong> - <kbd>TRUE/FALSE</kbd> (boolean). Whether to enable debugging to display error messages.</li>
-<li><strong>passive</strong> - <kbd>TRUE/FALSE</kbd> (boolean). Whether to use passive mode.  Passive is set automatically by default.</li>
-</ul>
-
-
-
-<h2>$this->ftp->upload()</h2>
-
-<p>Uploads a file to your server.  You must supply the local path and the remote path, and you can optionally set the mode and permissions.
-Example:</p>
-
-
-<code>$this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775);</code>
-
-<p><strong>Mode options are:</strong>&nbsp; <kbd>ascii</kbd>, <kbd>binary</kbd>, and <kbd>auto</kbd> (the default). If
-<kbd>auto</kbd> is used it will base the mode on the file extension of the source file.</p>
-
-<p>Permissions are available if you are running PHP 5 and can be passed as an <kbd>octal</kbd> value in the fourth parameter.</p>
-
-
-<h2>$this->ftp->download()</h2>
-
-<p>Downloads a file from your server.  You must supply the remote path and the local path, and you can optionally set the mode.
-Example:</p>
-
-<code>$this->ftp->download('/public_html/myfile.html', '/local/path/to/myfile.html', 'ascii');</code>
-
-<p><strong>Mode options are:</strong>&nbsp; <kbd>ascii</kbd>, <kbd>binary</kbd>, and <kbd>auto</kbd> (the default). If
-<kbd>auto</kbd> is used it will base the mode on the file extension of the source file.</p>
-
-<p>Returns FALSE if the download does not execute successfully (including if PHP does not have permission to write the local file)</p>
-
-
-<h2>$this->ftp->rename()</h2>
-<p>Permits you to rename a file.  Supply the source file name/path and the new file name/path.</p>
-
-<code>
-// Renames green.html to blue.html<br />
-$this->ftp->rename('/public_html/foo/green.html', '/public_html/foo/blue.html');
-</code>
-
-<h2>$this->ftp->move()</h2>
-<p>Lets you move a file.  Supply the source and destination paths:</p>
-
-<code>
-// Moves blog.html from "joe" to "fred"<br />
-$this->ftp->move('/public_html/joe/blog.html', '/public_html/fred/blog.html');
-</code>
-
-<p>Note: if the destination file name is different the file will be renamed.</p>
-
-
-<h2>$this->ftp->delete_file()</h2>
-<p>Lets you delete a file.  Supply the source path with the file name.</p>
-
-<code>
-$this->ftp->delete_file('/public_html/joe/blog.html');
-</code>
-
-
-<h2>$this->ftp->delete_dir()</h2>
-<p>Lets you delete a directory and everything it contains.  Supply the source path to the directory with a trailing slash.</p>
-
-<p class="important"><strong>Important</strong>&nbsp; Be VERY careful with this function.  It will recursively delete
-<b>everything</b> within the supplied path, including sub-folders and all files.  Make absolutely sure your path is correct.
-Try using the <kbd>list_files()</kbd> function first to verify that your path is correct.</p>
-
-<code>
-$this->ftp->delete_dir('/public_html/path/to/folder/');
-</code>
-
-
-
-<h2>$this->ftp->list_files()</h2>
-<p>Permits you to retrieve a list of files on your server returned as an <dfn>array</dfn>.  You must supply
-the path to the desired directory.</p>
-
-<code>
-$list = $this->ftp->list_files('/public_html/');<br />
-<br />
-print_r($list);
-</code>
-
-
-<h2>$this->ftp->mirror()</h2>
-
-<p>Recursively reads a local folder and everything it contains (including sub-folders) and creates a
-mirror via FTP based on it.  Whatever the directory structure of the original file path will be recreated on the server.
-You must supply a source path and a destination path:</p>
-
-<code>
-$this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/');
-</code>
-
-
-
-<h2>$this->ftp->mkdir()</h2>
-
-<p>Lets you create a directory on your server.  Supply the path ending in the folder name you wish to create, with a trailing slash.
-Permissions can be set by passed an <kbd>octal</kbd> value in the second parameter (if you are running PHP 5).</p>
-

-<h1>Image Manipulation Class</h1>
-
-<p>CodeIgniter's Image Manipulation class lets you perform the following actions:</p>
-
-<ul>
-<li>Image Resizing</li>
-<li>Thumbnail Creation</li>
-<li>Image Cropping</li>
-<li>Image Rotating</li>
-<li>Image Watermarking</li>
-</ul>
-
-<p>All three major image libraries are supported:  GD/GD2, NetPBM, and ImageMagick</p>
-
-<p class="important"><strong>Note:</strong> Watermarking is only available using the GD/GD2 library.
-In addition, even though other libraries are supported, GD is required in
-order for the script to calculate the image properties.  The image processing, however, will be performed with the
-library you specify.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the image class is initialized in your controller
-using the <dfn>$this->load-&gt;library</dfn> function:</p>
-<code>$this->load->library('image_lib');</code>
-
-<p>Once the library is loaded it will be ready for use.  The image library object you will use to call all functions is: <dfn>$this->image_lib</dfn></p>
-
-
-<h2>Processing an Image</h2>
-
-<p>Regardless of the type of processing you would like to perform (resizing, cropping, rotation, or watermarking), the general process is
-identical. You will set some preferences corresponding to the action you intend to perform, then
-call one of four available processing functions.  For example, to create an image thumbnail you'll do this:</p>
-
-<code>$config['image_library'] = 'gd2';<br />
-$config['source_image']	= '/path/to/image/mypic.jpg';<br />
-$config['create_thumb'] = TRUE;<br />
-$config['maintain_ratio'] = TRUE;<br />
-$config['width']		= 75;<br />
-$config['height']	= 50;<br />
-<br />
-$this->load->library('image_lib', $config);
-<br />
-<br />
-$this->image_lib->resize();</code>
-
-<p>The above code tells the <dfn>image_resize</dfn> function to look for an image called <em>mypic.jpg</em>
-located in the <dfn>source_image</dfn> folder, then create a thumbnail that is 75 X 50 pixels using the GD2 <dfn>image_library</dfn>.
-Since the <dfn>maintain_ratio</dfn> option is enabled, the thumb will be as close to the target <dfn>width</dfn> and
-<dfn>height</dfn> as possible while preserving the original aspect ratio.  The thumbnail will be called <em>mypic_thumb.jpg</em>
-</p>
-
-<p class="important"><strong>Note:</strong> In order for the image class to be allowed to do any processing, the
-folder containing the image files must have write permissions.</p>
-
-<p class="important"><strong>Note:</strong> Image processing can require a considerable amount of server memory for some operations. If you are experiencing out of memory errors while processing images you may need to limit their maximum size, and/or adjust PHP memory limits.</p>
-
-<h2>Processing Functions</h2>
-
-<p>There are four available processing functions:</p>
-
-<ul>
-<li>$this->image_lib->resize()</li>
-<li>$this->image_lib->crop()</li>
-<li>$this->image_lib->rotate()</li>
-<li>$this->image_lib->watermark()</li>
-<li>$this-&gt;image_lib-&gt;clear()</li>
-</ul>
-
-<p>These functions return boolean TRUE upon success and FALSE for failure.  If they fail you can retrieve the
-error message using this function:</p>
-
-<code>echo $this->image_lib->display_errors();</code>
-
-<p>A good practice is use the processing function conditionally, showing an error upon failure, like this:</p>
-
-<code>if ( ! $this->image_lib->resize())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $this->image_lib->display_errors();<br />
-}</code>
-
-<p>Note:  You can optionally specify the HTML formatting to be applied to the errors, by submitting the opening/closing
-tags in the function, like this:</p>
-
-<code>$this->image_lib->display_errors('<var>&lt;p></var>', '<var>&lt;/p></var>');</code>
-
-
-<h2>Preferences</h2>
-
-<p>The  preferences described below allow you to tailor the image processing to suit your needs.</p>
-
-<p>Note that not all preferences are available for every
-function.  For example, the x/y axis preferences are only available for image cropping. Likewise, the width and height
-preferences have no effect on cropping.  The "availability" column indicates which functions support a given preference.</p>
-
-<p>Availability Legend:</p>
-
-<ul>
-<li><var>R</var> - Image Resizing</li>
-<li><var>C</var> - Image Cropping</li>

-<h2>Setting preferences in a config file</h2>
-
-<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
-Simply create a new file called <var>image_lib.php</var>,  add the <var>$config</var>
-array in that file. Then save the file in: <var>config/image_lib.php</var> and it will be used automatically. You
-will NOT need to use the <dfn>$this->image_lib->initialize</dfn> function if you save your preferences in a config file.</p>
-
-
-<h2>$this->image_lib->resize()</h2>
-
-<p>The image resizing function lets you resize the original image, create a copy (with or without resizing),
-or create a thumbnail image.</p>
-
-<p>For practical purposes there is no difference between creating a copy and creating
-a thumbnail except a thumb will have the thumbnail marker as part of the name (ie, mypic_thumb.jpg).</p>
-
-<p>All preferences listed in the table above are available for this function except these three:  rotation_angle, x_axis, and y_axis.</p>
-
-<h3>Creating a Thumbnail</h3>
-
-<p>The resizing function will create a thumbnail file (and preserve the original) if you set this preference to TRUE:</p>
-
-<code>$config['create_thumb'] = TRUE;</code>
-
-<p>This single preference determines whether a thumbnail is created or not.</p>
-
-<h3>Creating a Copy</h3>
-
-<p>The resizing function will create a copy of the image file (and preserve the original) if you set
-a path and/or a new filename using this preference:</p>
-
-<code>$config['new_image'] = '/path/to/new_image.jpg';</code>
-
-<p>Notes regarding this preference:</p>
-<ul>
-<li>If only the new image name is specified it will be placed in the same folder as the original</li>
-<li>If only the path is specified, the new image will be placed in the destination with the same name as the original.</li>
-<li>If both the path and image name are specified it will placed in its own destination and given the new name.</li>
-</ul>
-
-
-<h3>Resizing the Original Image</h3>
-
-<p>If neither of the two preferences listed above (create_thumb, and new_image) are used, the resizing function will instead
-target the original image for processing.</p>
-
-
-<h2>$this->image_lib->crop()</h2>
-
-<p>The cropping function works nearly identically to the resizing function except it requires that you set
-preferences for the X and Y axis (in pixels) specifying where to crop, like this:</p>
-
-<code>$config['x_axis'] = '100';<br />
-$config['y_axis'] = '40';</code>
-
-<p>All preferences listed in the table above are available for this function except these:  rotation_angle, width, height, create_thumb, new_image.</p>
-
-<p>Here's an example showing how you might crop an image:</p>
-
-<code>$config['image_library'] = 'imagemagick';<br />
-$config['library_path'] = '/usr/X11R6/bin/';<br />
-$config['source_image']	= '/path/to/image/mypic.jpg';<br />
-$config['x_axis'] = '100';<br />
-$config['y_axis'] = '60';<br />
-<br />
-$this->image_lib->initialize($config);
-<br />
-<br />
-if ( ! $this->image_lib->crop())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $this->image_lib->display_errors();<br />
-}</code>
-
-
-<p>Note: Without a visual interface it is difficult to crop images, so this function is not very useful
-unless you intend to build such an interface.  That's exactly what we did using for the photo
-gallery module in ExpressionEngine, the CMS we develop.  We added a JavaScript UI that lets the cropping
-area be selected.</p>
-
-<h2>$this->image_lib->rotate()</h2>
-
-<p>The image rotation function requires that the angle of rotation be set via its preference:</p>
-
-<code>$config['rotation_angle'] = '90';</code>
-
-<p>There are 5 rotation options:</p>
-
-<ol>
-<li>90 - rotates counter-clockwise by 90 degrees.</li>
-<li>180 - rotates counter-clockwise by 180 degrees.</li>
-<li>270 - rotates counter-clockwise by 270 degrees.</li>
-<li>hor - flips the image horizontally.</li>
-<li>vrt - flips the image vertically.</li>
-</ol>
-
-<p>Here's an example showing how you might rotate an image:</p>
-
-<code>$config['image_library'] = 'netpbm';<br />
-$config['library_path'] = '/usr/bin/';<br />
-$config['source_image']	= '/path/to/image/mypic.jpg';<br />
-$config['rotation_angle'] = 'hor';<br />
-<br />
-$this->image_lib->initialize($config);
-<br />
-<br />
-if ( ! $this->image_lib->rotate())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $this->image_lib->display_errors();<br />
-}</code>
-
-
-
-<h2>$this-&gt;image_lib-&gt;clear()</h2>
-<p>The clear function resets all of the values used when processing an image. You will want to call this if you are processing images in a loop.</p>
-<p><code>$this-&gt;image_lib-&gt;clear();</code></p>
-<p>&nbsp;</p>
-<h1>Image Watermarking</h1>
-
-<p>The Watermarking feature requires the GD/GD2 library.</p>
-
-
-<h2>Two Types of Watermarking</h2>
-
-<p>There are two types of watermarking that you can use:</p>
-
-<ul>
-<li><strong>Text</strong>: The watermark message will be generating using text, either with a True Type font that you specify, or
-using the native text output that the GD library supports. If you use the True Type version your GD installation
-must be compiled with True Type support (most are, but not all).</li>
-
-<li><strong>Overlay</strong>: The watermark message will be generated by overlaying an image (usually a transparent PNG or GIF)
-containing your watermark over the source image.</li>
-
-</ul>
-
-
-<h2>Watermarking an Image</h2>
-
-<p>Just as with the other functions (resizing, cropping, and rotating) the general process for watermarking
-involves setting the preferences corresponding to the action you intend to perform, then
-calling the watermark function.  Here is an example:</p>
-
-<code>
-$config['source_image']	= '/path/to/image/mypic.jpg';<br />
-$config['wm_text'] = 'Copyright 2006 - John Doe';<br />
-$config['wm_type'] = 'text';<br />
-$config['wm_font_path'] = './system/fonts/texb.ttf';<br />
-$config['wm_font_size']	= '16';<br />
-$config['wm_font_color'] = 'ffffff';<br />
-$config['wm_vrt_alignment']  = 'bottom';<br />
-$config['wm_hor_alignment']  = 'center';<br />
-$config['wm_padding']  = '20';<br />
-<br />
-$this->image_lib->initialize($config);
-<br />
-<br />
-$this->image_lib->watermark();</code>
-
-
-<p>The above example will use a 16 pixel True Type font to create the text "Copyright 2006 - John Doe".  The watermark
-will be positioned at the bottom/center of the image, 20 pixels from the bottom of the image.</p>
-
-<p class="important"><strong>Note:</strong> In order for the image class to be allowed to do any processing, the image file must have &quot;write&quot; file permissions. For example, 777.</p>
-
-
-<h2>Watermarking Preferences</h2>

-<h1>Input Class</h1>
-
-<p>The Input Class serves two purposes:</p>
-
-<ol>
-<li>It pre-processes global input data for security.</li>
-<li>It provides some helper functions for fetching input data and pre-processing it.</li>
-</ol>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-
-<h2>Security Filtering</h2>
-
-<p>The security filtering function is called automatically when a new <a href="../general/controllers.html">controller</a> is invoked.  It does the following:</p>
-
-<ul>
-<li>If $config['allow_get_array'] is FALSE(default is TRUE), destroys the global GET array.</li>
-<li>Destroys all global variables in the event register_globals is turned on.</li>
-<li>Filters the GET/POST/COOKIE array keys, permitting only alpha-numeric (and a few other) characters.</li>
-<li>Provides XSS (Cross-site Scripting Hacks) filtering.  This can be enabled globally, or upon request.</li>
-<li>Standardizes newline characters to \n(In Windows \r\n)</li>
-</ul>
-
-
-<h2>XSS Filtering</h2>
-
-<p>The Input class has the ability to filter input automatically to prevent cross-site scripting attacks.  If you want the filter to run automatically every time it encounters POST or COOKIE data you can enable it by opening your
-<kbd>application/config/config.php</kbd> file and setting this:</p>
-
-<code>$config['global_xss_filtering'] = TRUE;</code>
-
-<p>Please refer to the <a href="security.html">Security class</a> documentation for information on using XSS Filtering in your application.</p>
-
-
-<h2>Using POST, COOKIE, or SERVER Data</h2>
-
-<p>CodeIgniter comes with three helper functions that let you fetch POST, COOKIE or SERVER items.  The main advantage of using the provided
-functions rather than fetching an item directly ($_POST['something']) is that the functions will check to see if the item is set and
-return false (boolean) if not.  This lets you conveniently use data without having to test whether an item exists first.
-In other words, normally you might do something like this:</p>
-
-<code>
-if ( ! isset($_POST['something']))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$something = FALSE;<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$something = $_POST['something'];<br />
-}</code>
-
-<p>With CodeIgniter's built in functions you can simply do this:</p>
-
-<code>$something = $this->input->post('something');</code>
-
-<p>The three functions are:</p>
-
-<ul>
-<li>$this->input->post()</li>
-<li>$this->input->cookie()</li>
-<li>$this->input->server()</li>
-</ul>
-
-<h2>$this->input->post()</h2>
-
-<p>The first parameter will contain the name of the POST item you are looking for:</p>
-
-<code>$this->input->post('some_data');</code>
-
-<p>The function returns FALSE (boolean) if the item you are attempting to retrieve does not exist.</p>
-
-<p>The second optional parameter lets you run the data through the XSS filter.  It's enabled by setting the second parameter to boolean TRUE;</p>
-
-<code>$this->input->post('some_data', TRUE);</code>
-
-<p>To return an array of all POST items call without any parameters.</p>
-<p>To return all POST items and pass them through the XSS filter set the first parameter NULL while setting the second parameter to boolean;</p>
-<p>The function returns FALSE (boolean) if there are no items in the POST.</p>
-
-<code>
-	$this->input->post(NULL, TRUE); // returns all POST items with XSS filter
-	<br />
-	$this->input->post(); // returns all POST items without XSS filter
-</code>
-
-<h2>$this->input->get()</h2>
-
-<p>This function is identical to the post function, only it fetches get data:</p>
-
-<code>$this->input->get('some_data', TRUE);</code>
-
-<p>To return an array of all GET items call without any parameters.</p>
-<p>To return all GET items and pass them through the XSS filter set the first parameter NULL while setting the second parameter to boolean;</p>
-<p>The function returns FALSE (boolean) if there are no items in the GET.</p>
-
-<code>
-	$this->input->get(NULL, TRUE); // returns all GET items with XSS filter
-	<br />
-	$this->input->get(); // returns all GET items without XSS filtering
-</code>
-
-<h2>$this->input->get_post()</h2>
-
-<p>This function will search through both the post and get streams for data, looking first in post, and then in get:</p>
-
-<code>$this->input->get_post('some_data', TRUE);</code>
-
-<h2>$this->input->cookie()</h2>
-
-<p>This function is identical to the post function, only it fetches cookie data:</p>
-
-<code>$this->input->cookie('some_data', TRUE);</code>
-
-<h2>$this->input->server()</h2>
-
-<p>This function is identical to the above functions, only it fetches server data:</p>
-
-<code>$this->input->server('some_data');</code>
-
-
-<h2>$this->input->set_cookie()</h2>
-
-<p>Sets a cookie containing the values you specify.  There are two ways to pass information to this function so that a cookie can be set:
-Array Method, and Discrete Parameters:</p>
-
-<h4>Array Method</h4>
-
-<p>Using this method, an associative array is passed to the first parameter:</p>
-
-<code>$cookie = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp;=> 'The Cookie Name',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'value'&nbsp;&nbsp;=> 'The Value',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'expire' => '86500',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'domain' => '.some-domain.com',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'path'&nbsp;&nbsp;&nbsp;=> '/',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'prefix' => 'myprefix_',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'secure' => TRUE<br />
-);<br />
-<br />
-$this->input->set_cookie($cookie);
-</code>
-
-<p><strong>Notes:</strong></p>
-
-<p>Only the name and value are required. To delete a cookie set it with the expiration blank.</p>
-
-<p>The expiration is set in <strong>seconds</strong>, which will be added to the current time.  Do not include the time, but rather only the
-number of seconds from <em>now</em> that you wish the cookie to be valid.  If the expiration is set to
-zero the cookie will only last as long as the browser is open.</p>
-<p>For site-wide cookies regardless of how your site is requested, add your URL to the <strong>domain</strong> starting with a period, like this:  .your-domain.com</p>
-<p>The path is usually not needed since the function sets a root path.</p>
-<p>The prefix is only needed if you need to avoid name collisions with other identically named cookies for your server.</p>
-<p>The secure boolean is only needed if you want to make it a secure cookie by setting it to TRUE.</p>
-
-<h4>Discrete Parameters</h4>
-
-<p>If you prefer, you can set the cookie by passing data using individual parameters:</p>
-
-<code>$this->input->set_cookie($name, $value, $expire, $domain, $path, $prefix, $secure);</code>
-
-<h2>$this->input->cookie()</h2>
-
-<p>Lets you fetch a cookie.  The first parameter will contain the name of the cookie you are looking for (including any prefixes):</p>
-
-<code>cookie('some_cookie');</code>
-
-<p>The function returns FALSE (boolean) if the item you are attempting to retrieve does not exist.</p>
-
-<p>The second optional parameter lets you run the data through the XSS filter.  It's enabled by setting the second parameter to boolean TRUE;</p>
-
-<p><code>cookie('some_cookie', TRUE);</code></p>
-
-
-<h2>$this->input->ip_address()</h2>
-<p>Returns the IP address for the current user.  If the IP address is not valid, the function will return an IP of: 0.0.0.0</p>
-<code>echo $this->input->ip_address();</code>
-
-
-<h2>$this->input->valid_ip(<var>$ip</var>)</h2>
-
-<p>Takes an IP address as input and returns TRUE or FALSE (boolean) if it is valid or not.  Note:  The $this->input->ip_address() function above
-validates the IP automatically.</p>
-
-<code>if ( ! $this-&gt;input-&gt;valid_ip($ip))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp; echo 'Not Valid';<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp; echo 'Valid';<br />
-}</code>
-
-
-<h2>$this->input->user_agent()</h2>
-<p>Returns the user agent (web browser) being used by the current user. Returns FALSE if it's not available.</p>
-<code>echo $this->input->user_agent();</code>
-<p>See the <a href="user_agent.html">User Agent Class</a> for methods which extract information from the user agent string.</p>
-
-<h2>$this->input->request_headers()</h2>
-<p>Useful if running in a non-Apache environment where <a href="http://php.net/apache_request_headers">apache_request_headers()</a> will not be supported.  Returns an array of headers.</p>
-
-<code>$headers = $this->input->request_headers();</code>
-
-<h2>$this->input->get_request_header();</h2>
-<p>Returns a single member of the request headers array.</p>
-
-<code>$this->input->get_request_header('some-header', TRUE);</code>
-
-
-<h2>$this->input->is_ajax_request()</h2>
-<p>Checks to see if the <var>HTTP_X_REQUESTED_WITH</var> server header has been set, and returns a boolean response.</p>
-
-
-<h2>$this->input->is_cli_request()</h2>
-<p>Checks to see if the <var>STDIN</var> constant is set, which is a failsafe way to see if PHP is being run on the command line.</p>
-
-<code>$this->input->is_cli_request()</code>

-
-<h1>Javascript Class</h1>
-<p>CodeIgniter provides a library to help you with certain common functions that you may want to use with Javascript. Please note that CodeIgniter does not require the jQuery library to run, and that any scripting library will work equally well. The jQuery library is simply presented as a convenience if you choose to use it.</p>
-<h2>Initializing the Class</h2>
-<p>To initialize the Javascript class manually in your controller constructor, use the <dfn>$this-&gt;load-&gt;library</dfn> function. Currently, the only available library is jQuery, which will automatically be loaded like this:</p>
-
-<code>$this-&gt;load-&gt;library('javascript');</code>
-
-<p>The Javascript class also accepts parameters, <dfn>js_library_driver (string) default 'jquery'</dfn> and <dfn>autoload (bool) default TRUE</dfn>.  You may override the defaults if you wish by sending an associative array:</p>
-
-<code>$this-&gt;load-&gt;library('javascript', array('js_library_driver' =&gt; 'scripto', 'autoload' =&gt; FALSE));</code>
-
-<p>Again, presently only 'jquery' is available.  You may wish to set <dfn>autoload</dfn> to FALSE, though, if you do not want the jQuery library to automatically include a script tag for the main jQuery script file.  This is useful if you are loading it from a location outside of CodeIgniter, or already have the script tag in your markup.</p>
-
-<p>Once loaded, the jQuery library object will be available using: <dfn>$this-&gt;javascript</dfn></p>
-<h2>Setup and Configuration</h2>
-<h3>Set these variables in your view</h3>
-<p>As a Javascript library, your files must be available to your application.</p>
-<p>As Javascript is a client side language, the library must be able to write content into your final output. This generally means a view. You'll need to include the following variables in the &lt;head&gt; sections of your output.</p>
-<p><code>&lt;?php echo $library_src;?&gt;<br />
-&lt;?php echo $script_head;?&gt;
-</code></p>
-<p>$library_src, is where the actual library file will be loaded, as well as any subsequent plugin script calls; $script_head is where specific events, functions and other commands will be rendered.</p>
-<h3>Set the path to the librarys with config items</h3>
-<p>There are some configuration items in Javascript library. These can either be set in application/config.php, within its own config/javascript.php file, or within any controller usings the set_item() function. </p>
-<p>An image to be used as an &quot;ajax loader&quot;, or progress indicator. Without one, the simple text message of &quot;loading&quot; will appear when Ajax calls need to be made.</p>
-<p><code>$config['javascript_location'] = 'http://localhost/codeigniter/themes/js/jquery/';<br />
-		$config['javascript_ajax_img'] = 'images/ajax-loader.gif';</code></p>
-<p>If you keep your files in the same directories they were downloaded from, then you need not set this configuration items.</p>
-
-<h2>The jQuery Class</h2>
-
-<p>To initialize the jQuery class manually in your controller constructor, use the <dfn>$this-&gt;load-&gt;library</dfn> function:</p>
-
-<code>$this-&gt;load-&gt;library('jquery');</code>
-
-<p>You may send an optional parameter to determine whether or not a script tag for the main jQuery file will be automatically included when loading the library.  It will be created by default.  To prevent this, load the library as follows:</p>
-
-<code>$this-&gt;load-&gt;library('jquery', FALSE);</code>
-
-<p>Once loaded, the jQuery library object will be available using: <dfn>$this-&gt;jquery</dfn></p>
-
-<h2>jQuery Events</h2>
-
-<p>Events are set using the following syntax.</p>
-
-<p><code>$this-&gt;jquery-&gt;event('element_path', code_to_run());</code></p>
-
-<p>In the above example:</p>
-
-<ul>
-	<li>&quot;event&quot; is any of blur, change, click, dblclick, error, focus, hover, keydown, keyup, load, mousedown, mouseup, mouseover, mouseup, resize, scroll, or unload.</li>
-	<li>&quot;element_path&quot; is any valid <a href="http://docs.jquery.com/Selectors">jQuery selector</a>. Due to jQuery's unique selector syntax, this is usually an element id, or CSS selector. For example &quot;#notice_area&quot; would effect &lt;div id=&quot;notice_area&quot;&gt;, and &quot;#content a.notice&quot; would effect all anchors with a class of &quot;notice&quot; in the div with id &quot;content&quot;.</li>
-	<li>&quot;code_to_run()&quot; is script your write yourself, or an action such as an effect from the jQuery library below.</li>
-	</ul>
-
-<h2>Effects</h2>
-
-<p>The query library supports a powerful <a href="http://docs.jquery.com/Effects">Effects</a> repertoire.  Before an effect can be used, it must be loaded:</p>
-
-<p><code>$this->jquery->effect([optional path] plugin name);
-// for example
-$this->jquery->effect('bounce');
-</code></p>
-
-<h3>hide() / show()</h3>
-
-<p>Each of this functions will affect the visibility of an item on your page. hide() will set an item invisible, show() will reveal it.</p>
-<p><code>$this-&gt;jquery-&gt;hide(target,  optional speed, optional extra information);<br />
-	$this-&gt;jquery-&gt;show(target,  optional speed, optional extra information);</code></p>
-
-<ul>

-<h1>Language Class</h1>
-
-<p>The Language Class provides functions to retrieve language files and lines of text for purposes of internationalization.</p>
-
-<p>In your CodeIgniter system folder you'll find one called <dfn>language</dfn> containing sets of language files.  You can create
-your own language files as needed in order to display error and other messages in other languages.</p>
-
-<p>Language files are typically stored in your <dfn>system/language</dfn> directory.  Alternately you can create a folder called <kbd>language</kbd> inside
-your <kbd>application</kbd> folder and store them there.  CodeIgniter will look first in your <dfn>application/language</dfn>
-directory.  If the directory does not exist or the specified language is not located there CI will instead look in your global
-<dfn>system/language</dfn> folder.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; Each language should be stored in its own folder.  For example, the English files are located at:
-<dfn>system/language/english</dfn></p>
-
-
-
-<h2>Creating Language Files</h2>
-
-<p>Language files must be named with <kbd>_lang.php</kbd> as the file extension.  For example, let's say you want to create a file
-containing error messages.  You might name it:  <kbd>error_lang.php</kbd></p>
-
-<p>Within the file you will assign each line of text to an array called <var>$lang</var> with this prototype:</p>
-
-<code>$lang['language_key'] = "The actual message to be shown";</code>
-
-<p><strong>Note:</strong> It's a good practice to use a common prefix for all messages in a given file to avoid collisions with
-similarly named items in other files.  For example, if you are creating error messages you might prefix them with <var>error_</var></p>
-
-<code>$lang['<var>error</var>_email_missing'] = "You must submit an email address";<br />
-$lang['<var>error</var>_url_missing'] = "You must submit a URL";<br />
-$lang['<var>error</var>_username_missing'] = "You must submit a username";</code>
-
-
-<h2>Loading A Language File</h2>
-
-<p>In order to fetch a line from a particular file you must load the file first.  Loading a language file is done with the following code:</p>
-
-<code>$this->lang->load('<samp>filename</samp>', '<dfn>language</dfn>');</code>
-
-<p>Where <samp>filename</samp> is the name of the file you wish to load (without the file extension), and <dfn>language</dfn>
-is the language set containing it (ie, english).  If the second parameter is missing, the default language set in your
-<kbd>application/config/config.php</kbd> file will be used.</p>
-
-
-<h2>Fetching a Line of Text</h2>
-
-<p>Once your desired language file is loaded you can access any line of text using this function:</p>
-
-<code>$this->lang->line('<samp>language_key</samp>');</code>
-
-<p>Where <samp>language_key</samp> is the array key corresponding to the line you wish to show.</p>
-
-<p>Note: This function simply returns the line.  It does not echo it for you.</p>
-
-<h3>Using language lines as form labels</h3>
-
-<p class="important">This feature has been deprecated from the language library and moved to the <kbd>lang()</kbd> function of the <a href="../helpers/language_helper.html">Language helper</a>.</p>
-
-<h2>Auto-loading Languages</h2>
-<p>If you find that you need a particular language globally throughout your application, you can tell CodeIgniter to <a href="../general/autoloader.html">auto-load</a> it during system initialization. This is done by opening the application/config/autoload.php file and adding the language(s) to the autoload array.</p>

-<h1>Loader Class</h1>
-
-<p>Loader, as the name suggests, is used to load elements.  These elements can be libraries (classes) <a href="../general/views.html">View files</a>,
-<a href="../general/helpers.html">Helpers</a>, <a href="../general/models.html">Models</a>, or your own files.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-<p>The following functions are available in this class:</p>
-
-
-<h2>$this->load->library('<var>class_name</var>', <samp>$config</samp>, <kbd>'object name'</kbd>)</h2>
-
-
-<p>This function is used to load core classes.  Where <var>class_name</var> is the name of the class you want to load.
-Note: We use the terms "class" and "library" interchangeably.</p>
-
-<p>For example, if you would like to send email with CodeIgniter, the first step is to load the email class within your controller:</p>
-
-<code>$this->load->library('email');</code>
-
-<p>Once loaded, the library will be ready for use, using <kbd>$this->email-></kbd><samp><em>some_function</em>()</samp>.</p>
-
-<p>Library files can be stored in subdirectories within the main "libraries" folder, or within your personal <dfn>application/libraries</dfn> folder.
-To load a file located in a subdirectory, simply include the path, relative to the "libraries" folder.
-For example, if you have file located at:</p>
-
-<code>libraries/flavors/chocolate.php</code>
-
-<p>You will load it using:</p>
-
-<code>$this->load->library('flavors/chocolate');</code>
-
-<p>You may nest the file in as many subdirectories as you want.</p>
-
-<p>Additionally, multiple libraries can be loaded at the same time by passing an array of libraries to the load function.</p>
-
-<code>$this->load->library(array('<var>email</var>', '<var>table</var>'));</code>
-
-<h3>Setting options</h3>
-
-<p>The second (optional) parameter allows you to optionally pass configuration setting.  You will typically pass these as an array:</p>
-
-<code>
-$config = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'mailtype' => 'html',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'charset'&nbsp; => 'utf-8,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'priority' => '1'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->load->library('email', $config);</code>
-
-<p>Config options can usually also be set via a config file. Each library is explained in detail in its own page, so please read the information regarding each one you would like to use.</p>
-
-<p>Please take note, when multiple libraries are supplied in an array for the first parameter, each will receive the same parameter information.</p>
-
-<h3>Assigning a Library to a different object name</h3>
-
-<p>If the third (optional) parameter is blank, the library will usually be assigned to an object with the same name as the library.  For example, if the library is named <dfn>Session</dfn>, it
-will be assigned to a variable named <dfn>$this->session</dfn>.</p>
-
-<p>If you prefer to set your own class names you can pass its value to the third parameter:</p>
-
-<code>$this->load->library('session', '', 'my_session');<br /><br />
-
-// Session class is now accessed using:<br /><br />
-
-$this->my_session
-
-</code>
-
-<p>Please take note, when multiple libraries are supplied in an array for the first parameter, this parameter is discarded.</p>
-
-
-<h2>$this->load->view('<var>file_name</var>', <samp>$data</samp>, <kbd>true/false</kbd>)</h2>
-
-<p>This function is used to load your View files.  If you haven't read the <a href="../general/views.html">Views</a> section of the
-user guide it is recommended that you do since it shows you how this function is typically used.</p>
-
-<p>The first parameter is required.  It is the name of the view file you would like to load. &nbsp;Note: The .php file extension does not need to be specified unless you use something other than <kbd>.php</kbd>.</p>
-
-<p>The second <strong>optional</strong> parameter can take
-an associative array or an object as input, which it runs through the PHP <a href="http://www.php.net/extract">extract</a> function to
-convert to variables that can be used in your view files.  Again, read the <a href="../general/views.html">Views</a> page to learn
-how this might be useful.</p>
-
-<p>The third <strong>optional</strong> parameter lets you change the behavior of the function so that it returns data as a string
-rather than sending it to your browser.  This can be useful if you want to process the data in some way.  If you
-set the parameter to <kbd>true</kbd> (boolean) it will return data.  The default behavior is <kbd>false</kbd>, which sends it
-to your browser.  Remember to assign it to a variable if you want the data returned:</p>
-
-<code>$string = $this->load->view('<var>myfile</var>', '', <kbd>true</kbd>);</code>
-
-
-<h2>$this-&gt;load-&gt;model('<var>Model_name</var>');</h2>
-<p><code>$this-&gt;load-&gt;model('<var>Model_name</var>');</code></p>
-<p>If your model is located in a sub-folder, include the relative path from your models folder. For example, if you have a model located at application/models/blog/queries.php you'll load it using:</p>
-<p><code>$this-&gt;load-&gt;model('<var>blog/queries</var>');</code></p>
-<p>If you would like your model assigned to a different object name you can specify it via the second parameter of the loading
-	function:</p>
-<code> $this-&gt;load-&gt;model('<var>Model_name</var>', '<kbd>fubar</kbd>');<br />
-<br />
-$this-&gt;<kbd>fubar</kbd>-&gt;function();</code>
-<h2>$this->load->database('<var>options</var>', <kbd>true/false</kbd>)</h2>
-<p>This function lets you load the database class.  The two parameters are <strong>optional</strong>.  Please see the
-<a href="../database/index.html">database</a> section for more info.</p>
-
-
-
-
-<h2>$this->load->vars(<samp>$array</samp>)</h2>
-
-<p>This function takes an associative array as input and generates variables using the PHP <a href="http://www.php.net/extract">extract</a> function.
-This function produces the same result as using the second parameter of the <dfn>$this->load->view()</dfn> function above.  The reason you might
-want to use this function independently is if you would like to set some global variables in the constructor of your controller
-and have them become available in any view file loaded from any function.  You can have multiple calls to this function.  The data get cached
-and merged into one array for conversion to variables.
-</p>
-
-
-<h2>$this->load->get_var(<samp>$key</samp>)</h2>
-
-<p>This function checks the associative array of variables available to your views. This is useful if for any reason a var is set in a library or another controller method using $this->load->vars().
-</p>
-
-
-<h2>$this->load->helper('<var>file_name</var>')</h2>
-<p>This function loads helper files, where <var>file_name</var> is the name of the file, without the <kbd>_helper.php</kbd> extension.</p>
-
-
-<h2>$this->load->file('<var>filepath/filename</var>', <kbd>true/false</kbd>)</h2>
-<p>This is a generic file loading function.  Supply the filepath and name in the first parameter and it will open and read the file.
-By default the data is sent to your browser, just like a View file, but if you set the second parameter to <kbd>true</kbd> (boolean)
-it will instead return the data as a string.</p>
-
-
-<h2>$this->load->language('<var>file_name</var>')</h2>
-<p>This function is an alias of the <a href="language.html">language loading function</a>: $this->lang->load()</p>
-
-<h2>$this->load->config('<var>file_name</var>')</h2>
-<p>This function is an alias of the <a href="config.html">config file loading function</a>: $this->config->load()</p>
-
-
-<h2>Application "Packages"</h2>
-
-<p>An application package allows for the easy distribution of complete sets of resources in a single directory, complete with its own libraries, models, helpers, config, and language files.  It is recommended that these packages be placed in the <dfn>application/third_party</dfn> folder.  Below is a sample map of an package directory</p>
-
-
-<h2>Sample Package "Foo Bar" Directory Map</h2>
-
-<p>The following is an example of a directory for an application package named "Foo Bar".</p>
-
-<code>/application/third_party/foo_bar<br />
-<br />
-config/<br />
-helpers/<br />
-language/<br />
-libraries/<br />
-models/<br />
-</code>
-
-<p>Whatever the purpose of the "Foo Bar" application package, it has its own config files, helpers, language files, libraries, and models.  To use these resources in your controllers, you first need to tell the Loader that you are going to be loading resources from a package, by adding the package path.</p>
-
-<h3>$this->load->add_package_path()</h3>
-
-<p>Adding a package path instructs the Loader class to prepend a given path for subsequent requests for resources.  As an example, the "Foo Bar" application package above has a library named <dfn>Foo_bar.php</dfn>. In our controller, we'd do the following:</p>
-
-<code>$this->load->add_package_path(<var>APPPATH</var>.'third_party/<var>foo_bar</var>/');<br />
-$this->load->library('foo_bar');</code>
-
-<h3>$this->load->remove_package_path()</h3>
-
-<p>When your controller is finished using resources from an application package, and particularly if you have other application packages you want to work with, you may wish to remove the package path so the Loader no longer looks in that folder for resources.  To remove the last path added, simply call the method with no parameters.</p>
-
-<h3>$this->load->remove_package_path()</h3>
-
-<p>Or to remove a specific package path, specify the same path previously given to <kbd>add_package_path() for a package.</kbd>:</p>
-
-<code>$this->load->remove_package_path(<var>APPPATH</var>.'third_party/<var>foo_bar</var>/');</code>
-
-<h3>Package view files</h3>
-
-<p>By Default, package view files paths are set when <samp>add_package_path()</samp> is called.  View paths are looped through, and once a match is encountered that view is loaded.</p>
-<p>In this instance, it is possible for view naming collisions within packages to occur, and possibly the incorrect package being loaded.  To ensure against this, set an optional second parameter of <var>FALSE</var> when calling <samp>add_package_path()</samp>.</p>
-
-<code>
-$this->load->add_package_path(APPPATH.'my_app', TRUE);<br>
-$this->load->view('my_app_index'); // Loads<br>
-$this->load->view('welcome_message'); // Will not load the default welcome_message b/c the second param to add_package_path is TRUE<br>
-<br>
-// Reset things<br>
-$this->load->remove_package_path(APPPATH.'my_app');<br>
-<br>
-// Again without the second parameter:<br>
-$this->load->add_package_path(APPPATH.'my_app', TRUE);<br>
-$this->load->view('my_app_index'); // Loads<br>
-$this->load->view('welcome_message'); // Loads<br>
-</code>

-<h1>Output Class</h1>
-
-<p>The Output class is a small class with one main function:  To send the finalized web page to the requesting browser.  It is
-also responsible for <a href="../general/caching.html">caching</a> your web pages, if you use that feature.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-<p>Under normal circumstances you won't even notice the Output class since it works transparently without your intervention.
-For example, when you use the <a href="../libraries/loader.html">Loader</a> class to load a view file, it's automatically
-passed to the Output class, which will be called automatically by CodeIgniter at the end of system execution.
-It is possible, however, for you to manually intervene with the output if you need to, using either of the two following functions:</p>
-
-<h2>$this->output->set_output();</h2>
-
-<p>Permits you to manually set the final output string.  Usage example:</p>
-
-<code>$this->output->set_output($data);</code>
-
-<p><strong>Important:</strong> If you do set your output manually, it must be the last thing done in the function you call it from.
-For example, if you build a page in one of your controller functions, don't set the output until the end.</p>
-
-
-<h2>$this->output->set_content_type();</h2>
-
-<p>Permits you to set the mime-type of your page so you can serve JSON data, JPEG's, XML, etc easily.</p>
-
-<code>$this->output<br/>
-&nbsp;&nbsp;&nbsp;&nbsp;->set_content_type('application/json')<br/>
-&nbsp;&nbsp;&nbsp;&nbsp;->set_output(json_encode(array('foo' => 'bar')));<br/>
-<br/>
-$this->output<br/>
-&nbsp;&nbsp;&nbsp;&nbsp;->set_content_type('jpeg') // You could also use ".jpeg" which will have the full stop removed before looking in config/mimes.php<br/>
-&nbsp;&nbsp;&nbsp;&nbsp;->set_output(file_get_contents('files/something.jpg'));</code>
-
-<p><strong>Important:</strong> Make sure any non-mime string you pass to this method exists in config/mimes.php or it will have no effect.</p>
-
-
-<h2>$this->output->get_output();</h2>
-
-<p>Permits you to manually retrieve any output that has been sent for storage in the output class.  Usage example:</p>
-<code>$string = $this->output->get_output();</code>
-
-<p>Note that data will only be retrievable from this function if it has been previously sent to the output class by one of the
-CodeIgniter functions like <var>$this->load->view()</var>.</p>
-
-
-<h2>$this->output->append_output();</h2>
-
-<p>Appends data onto the output string.  Usage example:</p>
-
-<code>$this->output->append_output($data);</code>
-
-
-
-<h2>$this->output->set_header();</h2>
-
-<p>Permits you to manually set server headers, which the output class will send for you when outputting the final rendered display.  Example:</p>
-
-<code>
-$this->output->set_header("HTTP/1.0 200 OK");<br />
-$this->output->set_header("HTTP/1.1 200 OK");<br />
-$this->output->set_header('Last-Modified: '.gmdate('D, d M Y H:i:s', $last_update).' GMT');<br />
-$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate");<br />
-$this->output->set_header("Cache-Control: post-check=0, pre-check=0");<br />
-$this->output->set_header("Pragma: no-cache");	</code>
-
-
-<h2>$this->output->set_status_header(<var>code</var>, '<var>text</var>');</h2>
-
-<p>Permits you to manually set a server status header.  Example:</p>
-
-<code>$this->output->set_status_header('401');<br />
-// Sets the header as:  Unauthorized</code>
-
-<p><a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html">See here</a> for a full list of headers.</p>
-
-<h2>$this->output->enable_profiler();</h2>
-
-<p>Permits you to enable/disable the <a href="../general/profiling.html">Profiler</a>, which will display benchmark and other data
-at the bottom of your pages for debugging and optimization purposes.</p>
-
-<p>To enable the profiler place the following function anywhere within your <a href="../general/controllers.html">Controller</a> functions:</p>
-<code>$this->output->enable_profiler(TRUE);</code>
-
-<p>When enabled a report will be generated and inserted at the bottom of your pages.</p>
-
-<p>To disable the profiler you will use:</p>
-<code>$this->output->enable_profiler(FALSE);</code>
-
-<h2>$this->output->set_profiler_sections();</h2>
-
-<p>Permits you to enable/disable specific sections of the Profiler when enabled.  Please refer to the <a href="../general/profiling.html">Profiler</a> documentation for further information.</p>
-
-<h2>$this->output->cache();</h2>
-<p>The CodeIgniter output library also controls caching.  For more information, please see the <a href="../general/caching.html">caching documentation</a>.</p>
-
-<h2>Parsing Execution Variables</h2>
-
-	<p>CodeIgniter will parse the pseudo-variables <var>{elapsed_time}</var> and <var>{memory_usage}</var> in your output by default.  To disable this, set the <var>$parse_exec_vars</var> class property to <var>FALSE</var> in your controller.
-
-	<code>$this->output->parse_exec_vars = FALSE;</code>

-<h1>Pagination Class</h1>
-
-<p>CodeIgniter's Pagination class is very easy to use, and it is 100% customizable, either dynamically or via stored preferences.</p>
-
-<p>If you are not familiar with the term "pagination", it refers to links that allows you to navigate from page to page, like this:</p>
-
-<code><a href="#">&laquo; First</a>&nbsp;&nbsp;<a href="#">&lt;</a>&nbsp;<a href="#">1</a>&nbsp;<a href="#">2</a>&nbsp;<b>3</b>&nbsp;<a href="#">4</a>&nbsp;<a href="#">5</a>&nbsp;<a href="#">&gt;</a>&nbsp;&nbsp;<a href="#">Last &raquo;</a></code>
-
-<h2>Example</h2>
-
-<p>Here is a simple example showing how to create pagination in one of your <a href="../general/controllers.html">controller</a> functions:</p>
-
-<code>
-$this->load->library('pagination');<br /><br />
-$config['base_url'] = 'http://example.com/index.php/test/page/';<br />
-$config['total_rows'] = 200;<br />
-$config['per_page']  = 20;
-<br /><br />
-$this->pagination->initialize($config);
-
-<br /><br />
-echo  $this->pagination->create_links();</code>
-
-<h3>Notes:</h3>
-
-<p>The <var>$config</var> array contains your configuration variables.  It is passed to the <dfn>$this->pagination->initialize</dfn> function as shown above.  Although there are some twenty items you can configure, at
-minimum you need the three shown.  Here is a description of what those items represent:</p>
-
-<ul>
-	<li><strong>base_url</strong> This is the full URL to the controller class/function containing your pagination.  In the example
-	above, it is pointing to a controller called "Test" and a function called "page".  Keep in mind that you can
-	<a href="../general/routing.html">re-route your URI</a> if you need a different structure.</li>
-	<li><strong>total_rows</strong> This number represents the total rows in the result set you are creating pagination for.
-	Typically this number will be the total rows that your database query returned.
-	</li>
-	<li><strong>per_page</strong> The number of items you intend to show per page.  In the above example, you would be showing 20 items per page.</li>
-</ul>
-
-<p>The <var>create_links()</var> function returns an empty string when there is no pagination to show.</p>
-
-
-<h3>Setting preferences in a config file</h3>
-
-<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
-Simply create a new file called <var>pagination.php</var>,  add the <var>$config</var>
-array in that file. Then save the file in: <var>config/pagination.php</var> and it will be used automatically. You
-will NOT need to use the <dfn>$this->pagination->initialize</dfn> function if you save your preferences in a config file.</p>
-
-
-<h2>Customizing the Pagination</h2>
-
-<p>The following is a list of all the preferences you can pass to the initialization function to tailor the display.</p>
-
-
-<h4>$config['uri_segment'] = 3;</h4>
-
-<p>The pagination function automatically determines which segment of your URI contains the page number. If you need
-something different you can specify it.</p>
-
-<h4>$config['num_links'] = 2;</h4>
-
-<p>The number of &quot;digit&quot; links you would like before and after the selected page number. For example, the number 2
-	will place two digits on either side, as in the example links at the very top of this page.</p>
-<h4>$config['page_query_string'] = TRUE</h4>
-<p>By default, the pagination library assume you are using <a href="../general/urls.html">URI Segments</a>, and constructs your links something like</p>
-<p><code>http://example.com/index.php/test/page/20</code></p>
-<p>If you have $config['enable_query_strings']  set to TRUE your links will automatically be re-written using Query Strings. This option can also be explictly set. Using $config['page_query_string'] set to TRUE, the pagination link will become.</p>
-<p><code>http://example.com/index.php?c=test&amp;m=page&amp;per_page=20</code></p>
-<p>Note that &quot;per_page&quot; is the default query string  passed, however can be configured using $config['query_string_segment'] = 'your_string'</p>
-<h2>Adding Enclosing Markup</h2>
-
-<p>If you would like to surround the entire pagination with some markup you can do it with these two prefs:</p>
-
-<h4>$config['full_tag_open'] = '&lt;p>';</h4>
-<p>The opening tag placed on the left side of the entire result.</p>
-
-<h4>$config['full_tag_close'] = '&lt;/p>';</h4>
-<p>The closing tag placed on the right side of the entire result.</p>
-
-
-<h2>Customizing the First Link</h2>
-
-<h4>$config['first_link'] = 'First';</h4>
-<p>The text you would like shown in the "first" link on the left. If you do not want this link rendered, you can set its value to FALSE.</p>
-
-<h4>$config['first_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "first" link.</p>
-
-<h4>$config['first_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "first" link.</p>
-
-<h2>Customizing the Last Link</h2>
-
-<h4>$config['last_link'] = 'Last';</h4>
-<p>The text you would like shown in the "last" link on the right. If you do not want this link rendered, you can set its value to FALSE.</p>
-
-<h4>$config['last_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "last" link.</p>
-
-<h4>$config['last_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "last" link.</p>
-
-<h2>Customizing the "Next" Link</h2>
-
-<h4>$config['next_link'] = '&amp;gt;';</h4>
-<p>The text you would like shown in the "next" page link. If you do not want this link rendered, you can set its value to FALSE.</p>
-
-<h4>$config['next_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "next" link.</p>
-
-<h4>$config['next_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "next" link.</p>
-
-<h2>Customizing the "Previous" Link</h2>
-
-<h4>$config['prev_link'] = '&amp;lt;';</h4>
-<p>The text you would like shown in the "previous" page link. If you do not want this link rendered, you can set its value to FALSE.</p>
-
-<h4>$config['prev_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "previous" link.</p>
-
-<h4>$config['prev_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "previous" link.</p>
-
-<h2>Customizing the "Current Page" Link</h2>
-
-<h4>$config['cur_tag_open'] = '&lt;b>';</h4>
-<p>The opening tag for the "current" link.</p>
-
-<h4>$config['cur_tag_close'] = '&lt;/b>';</h4>
-<p>The closing tag for the "current" link.</p>
-
-
-<h2>Customizing the "Digit" Link</h2>
-
-<h4>$config['num_tag_open'] = '&lt;div>';</h4>
-<p>The opening tag for the "digit" link.</p>
-
-<h4>$config['num_tag_close'] = '&lt;/div>';</h4>
-<p>The closing tag for the "digit" link.</p>
-
-<h2>Hiding the Pages</h2>
-
-<p>If you wanted to not list the specific pages (for example, you only want "next" and "previous" links), you can suppress their rendering by adding:</p>
-
-<code>
-$config['display_pages'] = FALSE;
-</code>
-
-
-<h2>Adding a class to every anchor</h2>
-
-<p>If you want to add a class attribute to every link rendered by the pagination class, you can set the config "anchor_class" equal to the classname you want.</p>

-<h1>Template Parser Class</h1>
-
-<p>The Template Parser Class enables you to parse pseudo-variables contained within your view files. It can parse simple
-variables or variable tag pairs. If you've never used a template engine, pseudo-variables look like this:</p>
-
-<code>&lt;html&gt;<br />
-&lt;head&gt;<br />
-&lt;title&gt;<kbd>{blog_title}</kbd>&lt;/title&gt;<br />
-&lt;/head&gt;<br />
-&lt;body&gt;<br />
-<br />
-&lt;h3&gt;<kbd>{blog_heading}</kbd>&lt;/h3&gt;<br />
-<br />
-<kbd>{blog_entries}</kbd><br />
-&lt;h5&gt;<kbd>{title}</kbd>&lt;/h5&gt;<br />
-&lt;p&gt;<kbd>{body}</kbd>&lt;/p&gt;<br />
-<kbd>{/blog_entries}</kbd><br />
-
-&lt;/body&gt;<br />
-&lt;/html&gt;</code>
-
-<p>These variables are not actual PHP variables, but rather plain text representations that allow you to eliminate
-PHP from your templates (view files).</p>
-
-<p class="important"><strong>Note:</strong> CodeIgniter does <strong>not</strong> require you to use this class
-since using pure PHP in your view pages lets them run a little faster.  However, some developers prefer to use a template engine if
-they work with designers who they feel would find some confusion working with PHP.</p>
-
-<p><strong>Also Note:</strong> The Template Parser Class is <strong>not</strong>  a
-full-blown template parsing solution. We've kept it very lean on purpose in order to maintain maximum performance.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Parser class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('parser');</code>
-<p>Once loaded, the Parser library object will be available using: <dfn>$this->parser</dfn></p>
-
-
-<p>The following functions are available in this library:</p>
-
-<h2>$this->parser->parse()</h2>
-
-<p>This method accepts a template name and data array as input, and it generates a parsed version.  Example:</p>
-
-<code>$this->load->library('parser');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_title' => 'My Blog Title',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_heading' => 'My Blog Heading'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->parser->parse('blog_template', $data);</code>
-
-<p>The first parameter contains the name of the <a href="../general/views.html">view file</a> (in this example the file would be called blog_template.php),
-and the second parameter contains an associative array of data to be replaced in the template.  In the above example, the
-template would contain two variables: {blog_title} and {blog_heading}</p>
-
-<p>There is no need to "echo" or do something with the data returned by <dfn>$this->parser->parse()</dfn>.  It is automatically
-passed to the output class to be sent to the browser.  However, if you do want the data returned instead of sent to the output class you can
-pass TRUE (boolean) to the third parameter:</p>
-
-<code>$string = $this->parser->parse('blog_template', $data, TRUE);</code>
-
-<h2>$this->parser->parse_string()</h2>
-
-<p>This method works exactly like parse(), only accepts a string as the first parameter in place of a view file.</p>
-
-
-<h2>Variable Pairs</h2>
-
-<p>The above example code allows simple variables to be replaced.  What if you would like an entire block of variables to be
-repeated, with each iteration containing new values?  Consider the template example we showed at the top of the page:</p>
-
-<code>&lt;html&gt;<br />
-&lt;head&gt;<br />
-&lt;title&gt;<kbd>{blog_title}</kbd>&lt;/title&gt;<br />
-&lt;/head&gt;<br />
-&lt;body&gt;<br />
-<br />
-&lt;h3&gt;<kbd>{blog_heading}</kbd>&lt;/h3&gt;<br />
-<br />
-<kbd>{blog_entries}</kbd><br />
-&lt;h5&gt;<kbd>{title}</kbd>&lt;/h5&gt;<br />
-&lt;p&gt;<kbd>{body}</kbd>&lt;/p&gt;<br />
-<kbd>{/blog_entries}</kbd><br />
-
-&lt;/body&gt;<br />
-&lt;/html&gt;</code>
-
-<p>In the above code you'll notice a pair of variables: <kbd>{blog_entries}</kbd> data... <kbd>{/blog_entries}</kbd>.
-In a case like this, the entire chunk of data between these pairs would be repeated multiple times, corresponding
-to the number of rows in a result.</p>
-
-<p>Parsing variable pairs is done using the identical code shown above to parse single variables,
-except, you will add a multi-dimensional array corresponding to your variable pair data.
-Consider this example:</p>
-
-
-<code>$this->load->library('parser');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_title'&nbsp;&nbsp; => 'My Blog Title',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_heading' => 'My Blog Heading',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_entries' => array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 1', 'body' => 'Body 1'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 2', 'body' => 'Body 2'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 3', 'body' => 'Body 3'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 4', 'body' => 'Body 4'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('title' => 'Title 5', 'body' => 'Body 5')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->parser->parse('blog_template', $data);</code>
-
-<p>If your "pair" data is coming from a database result, which is already a multi-dimensional array, you can simply
-use the database result_array() function:</p>
-
-<code>
-$query = $this->db->query("SELECT * FROM blog");<br />
-<br />
-$this->load->library('parser');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_title'&nbsp;&nbsp; => 'My Blog Title',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_heading' => 'My Blog Heading',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_entries' => $query->result_array()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->parser->parse('blog_template', $data);</code>

-<h1>Security Class</h1>
-
-<p>The Security Class contains methods that help you create a secure application, processing input data for security.</p>
-
-<h2>XSS Filtering</h2>
-
-<p>CodeIgniter comes with a Cross Site Scripting Hack prevention filter which can either run automatically to filter
-all POST and COOKIE data that is encountered, or you can run it on a per item basis.  By default it does <strong>not</strong>
-run globally since it requires a bit of processing overhead, and since you may not need it in all cases.</p>
-
-<p>The XSS filter looks for commonly used techniques to trigger Javascript or other types of code that attempt to hijack cookies
-or do other malicious things.  If anything disallowed is encountered it is rendered safe by converting the data to character entities.</p>
-
-<p>
-Note: This function should only be used to deal with data upon submission. It's not something that should be used for general runtime processing since it requires a fair amount of processing overhead.</p>
-
-
-<p>To filter data through the XSS filter use this function:</p>
-
-<h2>$this->security->xss_clean()</h2>
-
-<p>Here is an usage example:</p>
-
-<code>$data = $this->security->xss_clean($data);</code>
-
-<p>If you want the filter to run automatically every time it encounters POST or COOKIE data you can enable it by opening your
-<kbd>application/config/config.php</kbd> file and setting this:</p>
-
-<code>$config['global_xss_filtering'] = TRUE;</code>
-
-<p>Note: If you use the form validation class, it gives you the option of XSS filtering as well.</p>
-
-<p>An optional second parameter, <dfn>is_image</dfn>, allows this function to be used to test images for potential XSS attacks, useful for file upload security.  When this second parameter is set to <dfn>TRUE</dfn>, instead of returning an altered string, the function returns TRUE if the image is safe, and FALSE if it contained potentially malicious information that a browser may attempt to execute.</p>
-
-<code>if ($this->security->xss_clean($file, TRUE) === FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;// file failed the XSS test<br />
-}</code>
-
-
-<h2>$this->security->sanitize_filename()</h2>
-
-<p>When accepting filenames from user input, it is best to sanitize them to prevent directory traversal and other security related issues.  To do so, use the <dfn>sanitize_filename()</dfn> method of the Security class.  Here is an example:</p>
-
-<code>$filename = $this->security->sanitize_filename($this->input->post('filename'));</code>
-
-<p>If it is acceptable for the user input to include relative paths, e.g. <kbd>file/in/some/approved/folder.txt</kbd>, you can set the second optional parameter,
-	<samp>$relative_path</samp> to TRUE.</p>
-
-<code>$filename = $this->security->sanitize_filename($this->input->post('filename'), TRUE);</code>
-
-<!-- @todo write docs for CSRF methods -->
-
-<h2>Cross-site request forgery (CSRF)</h2>
-
-<p>You can enable csrf protection by opening your <kbd>application/config/config.php</kbd> file and setting this:</p>
-<code>$config['csrf_protection'] = TRUE;</code>
-
-<p>If you use the <a href="../helpers/form_helper.html">form helper</a> the <var>form_open()</var> function will automatically insert a hidden csrf field in your forms.</p>

-<h1>Session Class</h1>
-
-<p>The Session class permits you maintain a user's "state" and track their activity while they browse your site.
-The Session class stores session information for each user as serialized (and optionally encrypted) data in a cookie.
-It can also store the session data in a database table for added security, as this permits the session ID in the
-user's cookie to be matched against the stored session ID. By default only the cookie is saved.  If you choose to
-use the database option you'll need to create the session table as indicated below.
-</p>
-
-<p class="important"><strong>Note:</strong> The Session class does <strong>not</strong> utilize native PHP sessions. It
-generates its own session data, offering more flexibility for developers.</p>
-
-<p class="important"><strong>Note:</strong> Even if you are not using encrypted sessions, you must set
-an <a href="./encryption.html">encryption key</a> in your config file which is used to aid in preventing session data manipulation.</p>
-
-<h2>Initializing a Session</h2>
-
-<p>Sessions will typically run globally with each page load, so the session class must either be
-<a href="../general/libraries.html">initialized</a> in your
-<a href="../general/controllers.html">controller</a> constructors, or it can be
-<a href="../general/autoloader.html">auto-loaded</a> by the system.
-For the most part the session class will run unattended in the background, so simply initializing the class
-will cause it to read, create, and update sessions.</p>
-
-
-<p>To initialize the Session class manually in your controller constructor, use the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('session');</code>
-<p>Once loaded, the Sessions library object will be available using: <dfn>$this->session</dfn></p>
-
-
-<h2>How do Sessions work?</h2>
-
-<p>When a page is loaded, the session class will check to see if valid session data exists in the user's session cookie.
-If sessions data does <strong>not</strong> exist (or if it has expired) a new session will be created and saved in the cookie.
-If a session does exist, its information will be updated and the cookie will be updated. With each update, the session_id will be regenerated.</p>
-
-<p>It's important for you to understand that once initialized, the Session class runs automatically.  There is nothing
-you need to do to cause the above behavior to happen.  You can, as you'll see below, work with session data or
-even add your own data to a user's session, but the process of reading, writing, and updating a session is automatic.</p>
-
-
-<h2>What is Session Data?</h2>
-
-<p>A <em>session</em>, as far as CodeIgniter is concerned, is simply an array containing the following information:</p>
-
-<ul>
-<li>The user's unique Session ID (this is a statistically random string with very strong entropy, hashed with MD5 for portability, and regenerated (by default) every five minutes)</li>
-<li>The user's IP Address</li>
-<li>The user's User Agent data (the first 120 characters of the browser data string)</li>
-<li>The "last activity" time stamp.</li>
-</ul>
-
-<p>The above data is stored in a cookie as a serialized array with this prototype:</p>
-
-<code>[array]<br />
-(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'session_id'&nbsp;&nbsp;&nbsp;&nbsp;=> random hash,<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ip_address'&nbsp;&nbsp;&nbsp;&nbsp;=> 'string - user IP address',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'user_agent'&nbsp;&nbsp;&nbsp;&nbsp;=> 'string - user agent data',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'last_activity' => timestamp<br />
-)</code>
-
-<p>If you have the encryption option enabled, the serialized array will be encrypted before being stored in the cookie,
-making the data highly secure and impervious to being read or altered by someone. More info regarding encryption
-can be <a href="encryption.html">found here</a>, although the Session class will take care of initializing
-and encrypting the data automatically.</p>
-
-<p>Note: Session cookies are only updated every five minutes by default to reduce processor load.  If you repeatedly reload a page
-you'll notice that the "last activity" time only updates if five minutes or more has passed since the last time
-the cookie was written. This time is configurable by changing the $config['sess_time_to_update'] line in your system/config/config.php file.</p>
-
-<h2>Retrieving Session Data</h2>
-
-<p>Any piece of information from the session array is available using the following function:</p>
-
-<code>$this->session->userdata('<samp>item</samp>');</code>
-
-<p>Where <samp>item</samp> is the array index corresponding to the item you wish to fetch.  For example, to fetch the session ID you
-will do this:</p>
-
-<code>$session_id = $this->session->userdata('<samp>session_id</samp>');</code>
-
-<p><strong>Note:</strong> The function returns FALSE (boolean) if the item you are trying to access does not exist.</p>
-
-
-<h2>Adding Custom Session Data</h2>
-
-<p>A useful aspect of the session array is that you can add your own data to it and it will be stored in the user's cookie.
-Why would you want to do this?  Here's one example:</p>
-
-<p>Let's say a particular user logs into your site. Once authenticated,
-you could add their username and email address to the session cookie, making that data globally available to you without
-having to run a database query when you need it.</p>
-
-<p>To add your data to the session array involves passing an array containing your new data to this function:</p>
-
-<code>$this->session->set_userdata(<samp>$array</samp>);</code>
-
-<p>Where <samp>$array</samp> is an associative array containing your new data.  Here's an example:</p>
-
-
-<p><code>$newdata = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'username'&nbsp; => 'johndoe',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'email'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'johndoe@some-site.com',<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'logged_in' => TRUE<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-	<br />
-	$this->session->set_userdata(<samp>$newdata</samp>);</code></p>
-<p>If you want to add userdata one value at a time, set_userdata() also supports this syntax. </p>
-<p><code>$this-&gt;session-&gt;set_userdata('some_name', 'some_value');</code></p>
-<p class="important"><strong>Note:</strong> Cookies can only hold 4KB of data, so be careful not to exceed the capacity.  The
-encryption process in particular produces a longer data string than the original so keep careful track of how much data you are storing.</p>
-
-<h2>Retrieving All Session Data</h2>
-<p>An array of all userdata can be retrieved as follows:</p>
-<code>$this-&gt;session-&gt;all_userdata()</code>
-
-<p>And returns an associative array like the following:</p>
-
-<pre>
-Array
-(
-    [session_id] => 4a5a5dca22728fb0a84364eeb405b601
-    [ip_address] => 127.0.0.1
-    [user_agent] => Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_7;
-    [last_activity] => 1303142623
-)
-</pre>
-
-
-<h2>Removing Session Data</h2>
-<p>Just as set_userdata() can be used to add information into a session, unset_userdata() can be used to remove it, by passing the session key. For example, if you wanted to remove 'some_name' from your session information: </p>
-<p><code>$this-&gt;session-&gt;unset_userdata('some_name');</code></p>
-<p>This function can also be passed an associative array of items to unset.</p>
-<p><code>$array_items = array('username' => '', 'email' => '');<br />
-<br />
-$this-&gt;session-&gt;unset_userdata(<samp>$array_items</samp>);</code></p>
-<h2>Flashdata</h2>
-<p>CodeIgniter supports &quot;flashdata&quot;, or session data that will only be available for the next server request, and are then automatically cleared. These can be very useful, and are typically used for informational or status messages (for example: &quot;record 2 deleted&quot;).</p>
-<p>Note: Flash variables are prefaced with &quot;flash_&quot; so avoid this prefix in your own session names.</p>
-<p>To add flashdata:</p>
-<p><code>$this-&gt;session-&gt;set_flashdata('item', 'value');</code></p>
-<p>You can also pass an array to set_flashdata(), in the same manner as set_userdata(). </p>
-<p>To read a flashdata variable:</p>
-<p><code>$this-&gt;session-&gt;flashdata('item');</code></p>
-<p>If you find that you need to preserve a flashdata variable through an additional request, you can do so using the keep_flashdata() function.</p>
-<p><code>$this-&gt;session-&gt;keep_flashdata('item');</code></p>
-<h2>Saving Session Data to a Database</h2>
-<p>While the session data array stored in the user's cookie contains a Session ID,
-unless you store session data in a database there is no way to validate it.  For some applications that require little or no
-security, session ID validation may not be needed, but if your application requires security, validation is mandatory.  Otherwise, an old session
-could be restored by a user modifying their cookies.</p>
-
-<p>When session data is available in a database, every time a valid session is found in the user's cookie, a database
-query is performed to match it.  If the session ID does not match, the session is destroyed.  Session IDs can never
-be updated, they can only be generated when a new session is created.</p>
-
-
-<p>In order to store sessions, you must first create a database table for this purpose.  Here is the basic
-prototype (for MySQL) required by the session class:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-CREATE TABLE IF NOT EXISTS  `ci_sessions` (
-	session_id varchar(40) DEFAULT '0' NOT NULL,
-	ip_address varchar(16) DEFAULT '0' NOT NULL,
-	user_agent varchar(120) NOT NULL,
-	last_activity int(10) unsigned DEFAULT 0 NOT NULL,
-	user_data text NOT NULL,
-	PRIMARY KEY (session_id),
-	KEY `last_activity_idx` (`last_activity`)
-);
-</textarea>
-
-<p><strong>Note:</strong> By default the table is called <dfn>ci_sessions</dfn>, but you can name it anything you want
-as long as you update the <kbd>application/config/config.php</kbd> file so that it contains the name you have chosen.
-Once you have created your database table you can enable the database option in your config.php file as follows:</p>
-
-<code>$config['sess_use_database'] = TRUE;</code>
-
-<p>Once enabled, the Session class will store session data in the DB.</p>
-
-<p>Make sure you've specified the table name in your config file as well:</p>
-
-<code>$config['sess_table_name'] = 'ci_sessions';</code>
-
-<p class="important"><strong>Note:</strong> The Session class has built-in garbage collection which clears out expired sessions so you
-do not need to write your own routine to do it.</p>
-
-
-<h2>Destroying a Session </h2>
-<p>To clear the current session: </p>
-<code>$this-&gt;session-&gt;sess_destroy();</code>
-<p class="important"><strong>Note:</strong> This function should be the last one called, and even flash variables will no longer be available.  If you only want some items destroyed and not all, use <dfn>unset_userdata()</dfn>.</p>
-
-
-
-<h2>Session Preferences</h2>
-<p>You'll find the following Session related preferences in your <kbd>application/config/config.php</kbd> file:</p>
-
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">

-<h1>HTML Table Class</h1>
-
-<p>The Table Class provides functions that enable you to auto-generate HTML tables from arrays or database result sets.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Table class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('table');</code>
-<p>Once loaded, the Table library object will be available using: <dfn>$this->table</dfn></p>
-
-
-<h2>Examples</h2>
-
-<p>Here is an example showing how you can create a table from a multi-dimensional array.
-Note that the first array index will become the table heading (or you can set your own headings using the
-<dfn>set_heading()</dfn> function described in the function reference below).</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Name', 'Color', 'Size'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Fred', 'Blue', 'Small'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Mary', 'Red', 'Large'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('John', 'Green', 'Medium')	<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-echo $this->table->generate($data);
-</code>
-
-<p>Here is an example of a table created from a database query result. The table class will automatically generate the
-headings based on the table names (or you can set your own headings using the <dfn>set_heading()</dfn> function described
-in the function reference below).</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$query = $this->db->query("SELECT * FROM my_table");<br />
-<br />
-echo $this->table->generate($query);
-</code>
-
-
-<p>Here is an example showing how you might create a table using discrete parameters:</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$this->table->set_heading('Name', 'Color', 'Size');<br />
-<br />
-$this->table->add_row('Fred', 'Blue', 'Small');<br />
-$this->table->add_row('Mary', 'Red', 'Large');<br />
-$this->table->add_row('John', 'Green', 'Medium');<br />
-<br />
-echo $this->table->generate();
-</code>
-
-<p>Here is the same example, except instead of individual parameters, arrays are used:</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$this->table->set_heading(array('Name', 'Color', 'Size'));<br />
-<br />
-$this->table->add_row(array('Fred', 'Blue', 'Small'));<br />
-$this->table->add_row(array('Mary', 'Red', 'Large'));<br />
-$this->table->add_row(array('John', 'Green', 'Medium'));<br />
-<br />
-echo $this->table->generate();
-</code>
-
-
-<h2>Changing the Look of Your Table</h2>
-
-<p>The Table Class permits you to set a table template with which you can specify the design of your layout.  Here is the template
-prototype:</p>
-
-<code>
-$tmpl =  array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'table_open'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;table border="0" cellpadding="4" cellspacing="0">',<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading_row_start'&nbsp;&nbsp;&nbsp;=> '&lt;tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading_row_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading_cell_start'&nbsp;&nbsp;=> '&lt;th>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'heading_cell_end'&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/th>',<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'row_start'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'row_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'cell_start'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;td>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'cell_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/td>',<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'row_alt_start'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'row_alt_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/tr>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'cell_alt_start'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;td>',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'cell_alt_end'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/td>',<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'table_close'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '&lt;/table>'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-
-<br />
-$this->table->set_template($tmpl);
-</code>
-
-<p class="important"><strong>Note:</strong>&nbsp; You'll notice there are two sets of "row" blocks in the template.  These permit you to create alternating row colors or design elements that alternate with each
-iteration of the row data.</p>
-
-<p>You are NOT required to submit a complete template.  If you only need to change parts of the layout you can simply submit those elements.
-In this example, only the table opening tag is being changed:</p>
-
-<code>
-$tmpl =  array ( 'table_open'&nbsp;&nbsp;=> '&lt;table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />
-
-<br />
-$this->table->set_template($tmpl);
-</code>
-
-<br />
-<h1>Function Reference</h1>
-
-<h2>$this->table->generate()</h2>
-<p>Returns a string containing the generated table.  Accepts an optional parameter which can be an array or a database result object.</p>
-
-<h2>$this->table->set_caption()</h2>
-
-<p>Permits you to add a caption to the table.</p>
-
-<code>$this->table->set_caption('Colors');</code>
-
-<h2>$this->table->set_heading()</h2>
-
-<p>Permits you to set the table heading.  You can submit an array or discrete params:</p>
-
-<code>$this->table->set_heading('Name', 'Color', 'Size');</code>
-<code>$this->table->set_heading(array('Name', 'Color', 'Size'));</code>
-
-<h2>$this->table->add_row()</h2>
-
-<p>Permits you to add a row to your table.  You can submit an array or discrete params:</p>
-
-<code>$this->table->add_row('Blue', 'Red', 'Green');</code>
-<code>$this->table->add_row(array('Blue', 'Red', 'Green'));</code>
-
-<p>If you would like to set an individual cell's tag attributes, you can use an associative array for that cell.  The associative key <dfn>'data'</dfn> defines the cell's data.  Any other key =&gt; val pairs are added as <dfn>key='val'</dfn> attributes to the tag:</p>
-
-<code>$cell = array('data' => 'Blue', 'class' => 'highlight', 'colspan' => 2);<br />
-$this->table->add_row($cell, 'Red', 'Green');<br />
-<br />
-// generates<br />
-// &lt;td class='highlight' colspan='2'&gt;Blue&lt;/td&gt;&lt;td&gt;Red&lt;/td&gt;&lt;td&gt;Green&lt;/td&gt;
-</code>
-
-<h2>$this->table->make_columns()</h2>
-
-<p>This function takes a one-dimensional array as input and creates
-a multi-dimensional array with a depth equal to the number of
-columns desired.  This allows a single array with many elements to  be
-displayed in a table that has a fixed column count.  Consider this example:</p>
-
-<code>
-$list = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve');<br />
-<br />
-$new_list = $this->table->make_columns($list, 3);<br />
-<br />
-$this->table->generate($new_list);<br />
-<br />
-// Generates a table with this prototype<br />
-<br />
-&lt;table border="0" cellpadding="4" cellspacing="0"&gt;<br />
-&lt;tr&gt;<br />
-&lt;td&gt;one&lt;/td&gt;&lt;td&gt;two&lt;/td&gt;&lt;td&gt;three&lt;/td&gt;<br />
-&lt;/tr&gt;&lt;tr&gt;<br />
-&lt;td&gt;four&lt;/td&gt;&lt;td&gt;five&lt;/td&gt;&lt;td&gt;six&lt;/td&gt;<br />
-&lt;/tr&gt;&lt;tr&gt;<br />
-&lt;td&gt;seven&lt;/td&gt;&lt;td&gt;eight&lt;/td&gt;&lt;td&gt;nine&lt;/td&gt;<br />
-&lt;/tr&gt;&lt;tr&gt;<br />
-&lt;td&gt;ten&lt;/td&gt;&lt;td&gt;eleven&lt;/td&gt;&lt;td&gt;twelve&lt;/td&gt;&lt;/tr&gt;<br />
-&lt;/table&gt;</code>
-
-
-
-<h2>$this->table->set_template()</h2>
-
-<p>Permits you to set your template. You can submit a full or partial template.</p>
-
-<code>
-$tmpl =  array ( 'table_open'&nbsp;&nbsp;=> '&lt;table border="1" cellpadding="2" cellspacing="1" class="mytable">' );<br />
-
-<br />
-$this->table->set_template($tmpl);
-</code>
-
-
-<h2>$this->table->set_empty()</h2>
-
-<p>Let's you set a default value for use in any table cells that are empty.  You might, for example, set a non-breaking space:</p>
-
-<code>
-$this->table->set_empty("&amp;nbsp;");
-</code>
-
-<h2>$this->table->clear()</h2>
-
-<p>Lets you clear the table heading and row data.  If you need to show multiple tables with different data you should
-to call this function after each table has been generated to empty the previous table information. Example:</p>
-
-<code>
-$this->load->library('table');<br />
-<br />
-$this->table->set_heading('Name', 'Color', 'Size');<br />
-$this->table->add_row('Fred', 'Blue', 'Small');<br />
-$this->table->add_row('Mary', 'Red', 'Large');<br />
-$this->table->add_row('John', 'Green', 'Medium');<br />
-<br />
-echo $this->table->generate();<br />
-<br />
-<kbd>$this->table->clear();</kbd><br />
-<br />
-$this->table->set_heading('Name', 'Day', 'Delivery');<br />
-$this->table->add_row('Fred', 'Wednesday', 'Express');<br />
-$this->table->add_row('Mary', 'Monday', 'Air');<br />
-$this->table->add_row('John', 'Saturday', 'Overnight');<br />
-<br />
-echo $this->table->generate();
-</code>
-
-<h2>$this->table->function</h2>
-
-<p>Allows you to specify a native PHP function or a valid function array object to be applied to all cell data.</p>
-
-<code>$this->load->library('table');<br />
-<br />
-$this->table->set_heading('Name', 'Color', 'Size');<br />
-$this->table->add_row('Fred', '&lt;strong&gt;Blue&lt;/strong&gt;', 'Small');<br />
-<br />
-$this->table->function = 'htmlspecialchars';<br />
-echo $this->table->generate();<br />

-<h1>Trackback Class</h1>
-
-<p>The Trackback Class provides functions that enable you to send and receive Trackback data.</p>
-
-
-<p>If you are not familiar with Trackbacks you'll find more information <a href="http://en.wikipedia.org/wiki/Trackback">here</a>.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Trackback class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('trackback');</code>
-<p>Once loaded, the Trackback library object will be available using: <dfn>$this->trackback</dfn></p>
-
-
-<h2>Sending Trackbacks</h2>
-
-<p>A Trackback can be sent from any of your controller functions using code similar to this example:</p>
-
-<code>$this->load->library('trackback');<br />
-<br />
-$tb_data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ping_url'&nbsp;&nbsp;=> 'http://example.com/trackback/456',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'url'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'http://www.my-example.com/blog/entry/123',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'The Title of My Entry',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'excerpt'&nbsp;&nbsp;&nbsp;=> 'The entry content.',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_name' => 'My Blog Name',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'charset'&nbsp;&nbsp;&nbsp;=> 'utf-8'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-if ( ! $this->trackback->send($tb_data))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $this->trackback->display_errors();<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo 'Trackback was sent!';<br />
-}</code>
-
-<p>Description of array data:</p>
-
-<ul>
-<li><strong>ping_url</strong> - The URL of the site you are sending the Trackback to. You can send Trackbacks to multiple URLs by separating each URL with a comma.</li>
-<li><strong>url</strong> - The URL to YOUR site where the weblog entry can be seen.</li>
-<li><strong>title</strong> - The title of your weblog entry.</li>
-<li><strong>excerpt</strong> - The content of your weblog entry. Note: the Trackback class will automatically send only the first 500 characters of your entry.  It will also strip all HTML.</li>
-<li><strong>blog_name</strong> - The name of your weblog.</li>
-<li><strong>charset</strong> - The character encoding your weblog is written in.  If omitted, UTF-8 will be used.</li>
-</ul>
-
-<p>The Trackback sending function returns TRUE/FALSE (boolean) on success or failure.  If it fails, you can retrieve the error message using:</p>
-
-<code>$this->trackback->display_errors();</code>
-
-
-<h2>Receiving Trackbacks</h2>
-
-<p>Before you can receive Trackbacks you must create a weblog.  If you don't have a blog yet there's no point in continuing.</p>
-
-<p>Receiving Trackbacks is a little more complex than sending them, only because you will need a database table in which to store them,
-and you will need to validate the incoming trackback data.  You are encouraged to implement a thorough validation process to
-guard against spam and duplicate data.  You may also want to limit the number of Trackbacks you allow from a particular IP within
-a given span of time to further curtail spam.  The process of receiving a Trackback is quite simple;
-the validation is what takes most of the effort.</p>
-
-<h2>Your Ping URL</h2>
-
-<p>In order to accept Trackbacks you must display a Trackback URL next to each one of your weblog entries.  This will be the URL
-that people will use to send you Trackbacks (we will refer to this as your "Ping URL").</p>
-
-<p>Your Ping URL must point to a controller function where your Trackback receiving code is located, and the URL
-must contain the ID number for each particular entry, so that when the Trackback is received you'll be
-able to associate it with a particular entry.</p>
-
-<p>For example, if your controller class is called <dfn>Trackback</dfn>, and the receiving function is called <dfn>receive</dfn>, your
-Ping URLs will look something like this:</p>
-
-<code>http://example.com/index.php/trackback/receive/<samp>entry_id</samp></code>
-
-<p>Where <samp>entry_id</samp> represents the individual ID number for each of your entries.</p>
-
-
-<h2>Creating a Trackback Table</h2>
-
-<p>Before you can receive Trackbacks you must create a table in which to store them.  Here is a basic prototype for such a table:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="13">
-CREATE TABLE trackbacks (
- tb_id int(10) unsigned NOT NULL auto_increment,
- entry_id int(10) unsigned NOT NULL default 0,
- url varchar(200) NOT NULL,
- title varchar(100) NOT NULL,
- excerpt text NOT NULL,
- blog_name varchar(100) NOT NULL,
- tb_date int(10) NOT NULL,
- ip_address varchar(16) NOT NULL,
- PRIMARY KEY `tb_id` (`tb_id`),
- KEY `entry_id` (`entry_id`)
-);</textarea>
-
-
-<p>The Trackback specification only requires four pieces of information to be sent in a Trackback (url, title, excerpt, blog_name),
-but to make the data more useful we've added a few more fields in the above table schema (date, IP address, etc.).</p>
-
-<h2>Processing a Trackback</h2>
-
-<p>Here is an example showing how you will receive and process a Trackback.  The following
-code is intended for use within the controller function where you expect to receive Trackbacks.</p>
-
-<code>$this->load->library('trackback');<br />
-$this->load->database();<br />
-<br />
-if ($this->uri->segment(3) == FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->trackback->send_error("Unable to determine the entry ID");<br />
-}<br />
-<br />
-if ( ! $this->trackback->receive())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->trackback->send_error("The Trackback did not contain valid data");<br />
-}<br />
-<br />
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tb_id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'entry_id'&nbsp;&nbsp;&nbsp;=> $this->uri->segment(3),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'url'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> $this->trackback->data('url'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> $this->trackback->data('title'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'excerpt'&nbsp;&nbsp;&nbsp;&nbsp;=> $this->trackback->data('excerpt'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_name'&nbsp;&nbsp;=> $this->trackback->data('blog_name'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tb_date'&nbsp;&nbsp;&nbsp;&nbsp;=> time(),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ip_address' => $this->input->ip_address()<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$sql = $this->db->insert_string('trackbacks', $data);<br />
-$this->db->query($sql);<br />
-<br />
-$this->trackback->send_success();</code>
-
-<h4>Notes:</h4>
-
-<p>The entry ID number is expected in the third segment of your URL.  This is based on the URI example we gave earlier:</p>
-
-<code>http://example.com/index.php/trackback/receive/<samp>entry_id</samp></code>
-
-<p>Notice the entry_id is in the third URI segment, which you can retrieve using:</p>
-
-<code>$this->uri->segment(3);</code>
-
-<p>In our Trackback receiving code above, if the third segment is missing, we will issue an error.  Without a valid entry ID, there's no
-reason to continue.</p>
-
-<p>The <dfn>$this->trackback->receive()</dfn> function is simply a validation function that looks at the incoming data
-and makes sure it contains the four pieces of data that are required (url, title, excerpt, blog_name).
-It returns TRUE on success and FALSE on failure.  If it fails you will issue an error message.</p>
-
-<p>The incoming Trackback data can be retrieved using this function:</p>
-
-<code>$this->trackback->data('<var>item</var>')</code>
-
-<p>Where <var>item</var> represents one of these four pieces of info: url, title, excerpt, or blog_name</p>
-
-<p>If the Trackback data is successfully received, you will issue a success message using:</p>
-
-<code>$this->trackback->send_success();</code>
-
-<p class="important"><strong>Note:</strong> The above code contains no data validation, which you are encouraged to add.</p>

-<h1>Typography Class</h1>
-
-<p>The Typography Class provides functions that help you format text.</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Typography class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('typography');</code>
-<p>Once loaded, the Typography library object will be available using: <dfn>$this->typography</dfn></p>
-
-
-<h2>auto_typography()</h2>
-
-<p>Formats text so that it is semantically and typographically correct HTML.  Takes a string as input and returns it with
-the following formatting:</p>
-
-<ul>
-<li>Surrounds paragraphs within &lt;p&gt;&lt;/p&gt; (looks for double line breaks to identify paragraphs).</li>
-<li>Single line breaks are converted to &lt;br /&gt;, except those that appear within &lt;pre&gt; tags.</li>
-<li>Block level elements, like &lt;div&gt; tags, are not wrapped within paragraphs, but their contained text is if it contains paragraphs.</li>
-<li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li>
-<li>Apostrophes are converted to curly apostrophe entities.</li>
-<li>Double dashes (either like -- this or like--this) are converted to em&#8212;dashes.</li>
-<li>Three consecutive periods either preceding or following a word are converted to ellipsis&#8230;</li>
-<li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li>
-</ul>
-
-<p>Usage example:</p>
-
-<code>$string = $this->typography->auto_typography($string);</code>
-
-<h3>Parameters</h3>
-
-<p>There is one optional parameters that determines whether the parser should reduce more then two consecutive line breaks down to two. Use boolean <kbd>TRUE</kbd> or <kbd>FALSE</kbd>.</p>
-
-<p>By default the parser does not reduce line breaks. In other words, if no parameters are submitted, it is the same as doing this:</p>
-
-<code>$string = $this->typography->auto_typography($string, <kbd>FALSE</kbd>);</code>
-
-
-<p class="important"><strong>Note:</strong> Typographic formatting can be processor intensive, particularly if you have a lot of content being formatted.
-If you choose to use this function you may want to consider
-<a href="../general/caching.html">caching</a> your pages.</p>
-
-
-
-<h2>format_characters()</h2>
-
-<p>This function is similar to the <dfn>auto_typography</dfn> function above, except that it only does character conversion:</p>
-
-<ul>
-<li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li>
-<li>Apostrophes are converted to curly apostrophe entities.</li>
-<li>Double dashes (either like -- this or like--this) are converted to em&#8212;dashes.</li>
-<li>Three consecutive periods either preceding or following a word are converted to ellipsis&#8230;</li>
-<li>Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.</li>
-</ul>
-
-<p>Usage example:</p>
-
-<code>$string = $this->typography->format_characters($string);</code>
-
-
-<h2>nl2br_except_pre()</h2>
-
-<p>Converts newlines to &lt;br /&gt; tags unless they appear within &lt;pre&gt; tags.
-This function is identical to the native PHP <dfn>nl2br()</dfn> function, except that it ignores &lt;pre&gt; tags.</p>
-
-<p>Usage example:</p>
-
-<code>$string = $this->typography->nl2br_except_pre($string);</code>
-
-<h2>protect_braced_quotes</h2>
-
-<p>When using the Typography library in conjunction with the Template Parser library it can often be desirable to protect single
-	and double quotes within curly braces.  To enable this, set the <kbd>protect_braced_quotes</kbd> class property to <samp>TRUE</samp>.</p>
-
-<p>Usage example:</p>
-
-<code>$this->load->library('typography');<br />
-$this->typography->protect_braced_quotes = TRUE;
-</code>

-<h1>Unit Testing Class</h1>
-
-<p>Unit testing is an approach to software development in which tests are written for each function in your application.
-If you are not familiar with the concept you might do a little googling on the subject.</p>
-
-<p>CodeIgniter's Unit Test class is quite simple, consisting of an evaluation function and two result functions.
-It's not intended to be a full-blown test suite but rather a simple mechanism to evaluate your code
-to determine if it is producing the correct data type and result.
-</p>
-
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Unit Test class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('unit_test');</code>
-<p>Once loaded, the Unit Test object will be available using: <dfn>$this->unit</dfn></p>
-
-
-<h2>Running Tests</h2>
-
-<p>Running a test involves supplying a test and an expected result to the following function:</p>
-
-<h2>$this->unit->run( <var>test</var>, <var>expected result</var>, '<var>test name</var>', '<var>notes</var>');</h2>
-
-<p>Where <var>test</var> is the result of the code you wish to test, <var>expected result</var> is the data type you expect,
-<var>test name</var> is an optional name you can give your test, and <var>notes</var> are optional notes. Example:</p>
-
-<code>$test = 1 + 1;<br />
-<br />
-$expected_result = 2;<br />
-<br />
-$test_name = 'Adds one plus one';<br />
-<br />
-$this->unit->run($test, $expected_result, $test_name);</code>
-
-<p>The expected result you supply can either be a literal match, or a data type match.  Here's an example of a literal:</p>
-
-<code>$this->unit->run('Foo', 'Foo');</code>
-
-<p>Here is an example of a data type match:</p>
-
-<code>$this->unit->run('Foo', 'is_string');</code>
-
-<p>Notice the use of "is_string" in the second parameter?  This tells the function to evaluate whether your test is producing a string
-as the result.  Here is a list of allowed comparison types:</p>
-
-<ul>
-<li>is_object</li>
-<li>is_string</li>
-<li>is_bool</li>
-<li>is_true</li>
-<li>is_false</li>
-<li>is_int</li>
-<li>is_numeric</li>
-<li>is_float</li>
-<li>is_double</li>
-<li>is_array</li>
-<li>is_null</li>
-</ul>
-
-
-<h2>Generating Reports</h2>
-
-<p>You can either display results after each test, or your can run several tests and generate a report at the end.
-To show a report directly simply echo or return the <var>run</var> function:</p>
-
-<code>echo $this->unit->run($test, $expected_result);</code>
-
-<p>To run a full report of all tests, use this:</p>
-
-<code>echo $this->unit->report();</code>
-
-<p>The report will be formatted in an HTML table for viewing.  If you prefer the raw data you can retrieve an array using:</p>
-
-<code>echo $this->unit->result();</code>
-
-
-<h2>Strict Mode</h2>
-
-<p>By default the unit test class evaluates literal matches loosely.  Consider this example:</p>
-
-<code>$this->unit->run(1, TRUE);</code>
-
-<p>The test is evaluating an integer, but the expected result is a boolean.  PHP, however, due to it's loose data-typing
-will evaluate the above code as TRUE using a normal equality test:</p>
-
-<code>if (1 == TRUE) echo 'This evaluates as true';</code>
-
-<p>If you prefer, you can put the unit test class in to strict mode, which will compare the data type as well as the value:</p>
-
-<code>if (1 === TRUE) echo 'This evaluates as FALSE';</code>
-
-<p>To enable strict mode use this:</p>
-
-<code>$this->unit->use_strict(TRUE);</code>
-
-<h2>Enabling/Disabling Unit Testing</h2>
-
-<p>If you would like to leave some testing in place in your scripts, but not have it run unless you need it, you can disable
-unit testing using:</p>
-
-<code>$this->unit->active(FALSE)</code>
-
-<h2>Unit Test Display</h2>
-
-<p>When your unit test results display, the following items show by default:</p>
-
-<ul>
-	<li>Test Name (test_name)</li>
-	<li>Test Datatype (test_datatype)</li>
-	<li>Expected Datatype (res_datatype)</li>
-	<li>Result (result)</li>
-	<li>File Name (file)</li>
-	<li>Line Number (line)</li>
-	<li>Any notes you entered for the test (notes)</li>
-</ul>
-
-You can customize which of these items get displayed by using <kbd>$this->unit->set_items()</kbd>. For example, if you only wanted the test name and the result displayed:</p>
-
-<h3>Customizing displayed tests</h3>
-
-<code>
-	$this->unit->set_test_items(array('test_name', 'result'));
-</code>
-
-<h3>Creating a Template</h3>
-
-<p>If you would like your test results formatted differently then the default you can set your own template.  Here is an
-example of a simple template.  Note the required pseudo-variables:</p>
-
-<code>
-$str = '<br />
-&lt;table border="0" cellpadding="4" cellspacing="1"><br />
-&nbsp;&nbsp;&nbsp;&nbsp;<kbd>{rows}</kbd><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;tr><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;td><kbd>{item}</kbd>&lt;/td><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;td><kbd>{result}</kbd>&lt;/td><br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;/tr><br />
-&nbsp;&nbsp;&nbsp;&nbsp;<kbd>{/rows}</kbd><br />
-&lt;/table>';<br />
-<br />
-$this->unit->set_template($str);
-</code>
-
-<p class="important"><strong>Note:</strong> Your template must be declared <strong>before</strong> running the unit test process.</p>

-<h1>URI Class</h1>
-
-<p>The URI Class provides functions that help you retrieve information from your URI strings. If you use URI routing, you can
-also retrieve information about the re-routed segments.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-<h2>$this->uri->segment(<var>n</var>)</h2>
-
-<p>Permits you to retrieve a specific segment. Where <var>n</var> is the segment number you wish to retrieve.
-Segments are numbered from left to right. For example, if your full URL is this:</p>
-
-<code>http://example.com/index.php/news/local/metro/crime_is_up</code>
-
-<p>The segment numbers would be this:</p>
-
-<ol>
-<li>news</li>
-<li>local</li>
-<li>metro</li>
-<li>crime_is_up</li>
-</ol>
-
-<p>By default the function returns FALSE (boolean) if the segment does not exist. There is an optional second parameter that
-permits you to set your own default value if the segment is missing.
-For example, this would tell the function to return the number zero in the event of failure:</p>
-
-<code>$product_id = $this->uri->segment(3, 0);</code>
-
-<p>It helps avoid having to write code like this:</p>
-
-<code>if ($this->uri->segment(3) === FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$product_id = 0;<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$product_id = $this->uri->segment(3);<br />
-}<br />
-</code>
-
-<h2>$this->uri->rsegment(<var>n</var>)</h2>
-
-<p>This function is identical to the previous one, except that it lets you retrieve a specific segment from your
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-<h2>$this->uri->slash_segment(<var>n</var>)</h2>
-
-<p>This function is almost identical to <dfn>$this->uri->segment()</dfn>, except it adds a trailing and/or leading slash based on the second
-parameter.  If the parameter is not used, a trailing slash added.  Examples:</p>
-
-<code>$this->uri->slash_segment(<var>3</var>);<br />
-$this->uri->slash_segment(<var>3</var>, 'leading');<br />
-$this->uri->slash_segment(<var>3</var>, 'both');</code>
-
-<p>Returns:</p>
-
-<ol>
-<li>segment/</li>
-<li>/segment</li>
-<li>/segment/</li>
-</ol>
-
-
-<h2>$this->uri->slash_rsegment(<var>n</var>)</h2>
-
-<p>This function is identical to the previous one, except that it lets you add slashes a specific segment from your
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-
-<h2>$this->uri->uri_to_assoc(<var>n</var>)</h2>
-
-<p>This function lets you turn URI segments into and associative array of key/value pairs.  Consider this URI:</p>
-
-<code>index.php/user/search/name/joe/location/UK/gender/male</code>
-
-<p>Using this function you can turn the URI into an associative array with this prototype:</p>
-
-<code>[array]<br />
-(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'joe'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'location'	=> 'UK'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;'gender'	=> 'male'<br />
-)</code>
-
-<p>The first parameter of the function lets you set an offset.  By default it is set to <kbd>3</kbd> since your
-URI will normally contain a controller/function in the first and second segments. Example:</p>
-
-<code>
-$array = $this->uri->uri_to_assoc(3);<br />
-<br />
-echo $array['name'];
-</code>
-
-
-<p>The second parameter lets you set default key names, so that the array returned by the function will always contain expected indexes, even if missing from the URI. Example:</p>
-
-<code>
-$default = array('name', 'gender', 'location', 'type', 'sort');<br />
-<br />
-$array = $this->uri->uri_to_assoc(3, $default);</code>
-
-<p>If the URI does not contain a value in your default, an array index will be set to that name, with a value of FALSE.</p>
-
-<p>Lastly, if a corresponding value is not found for a given key (if there is an odd number of URI segments) the value will be set to FALSE (boolean).</p>
-
-
-<h2>$this->uri->ruri_to_assoc(<var>n</var>)</h2>
-
-<p>This function is identical to the previous one, except that it creates an associative array using the
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-<h2>$this->uri->assoc_to_uri()</h2>
-
-<p>Takes an associative array as input and generates a URI string from it.  The array keys will be included in the string.  Example:</p>
-
-<code>$array = array('product' => 'shoes', 'size' => 'large', 'color' => 'red');<br />
-<br />
-$str = $this->uri->assoc_to_uri($array);<br />
-<br />
-// Produces:  product/shoes/size/large/color/red
-</code>
-
-
-<h2>$this->uri->uri_string()</h2>
-
-<p>Returns a string with the complete URI.  For example, if this is your full URL:</p>
-
-<code>http://example.com/index.php/news/local/345</code>
-
-<p>The function would return this:</p>
-
-<code>/news/local/345</code>
-
-
-<h2>$this->uri->ruri_string()</h2>
-
-<p>This function is identical to the previous one, except that it returns the
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-
-<h2>$this->uri->total_segments()</h2>
-
-<p>Returns the total number of segments.</p>
-
-
-<h2>$this->uri->total_rsegments()</h2>
-
-<p>This function is identical to the previous one, except that it returns the total number of segments in your
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>
-
-
-
-<h2>$this->uri->segment_array()</h2>
-
-<p>Returns an array containing the URI segments.  For example:</p>
-
-<code>
-$segs = $this->uri->segment_array();<br />
-<br />
-foreach ($segs as $segment)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $segment;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo '&lt;br />';<br />
-}</code>
-
-<h2>$this->uri->rsegment_array()</h2>
-
-<p>This function is identical to the previous one, except that it returns the array of segments in your
-re-routed URI in the event you are using CodeIgniter's <a href="../general/routing.html">URI Routing</a> feature.</p>

-<h1>User Agent Class</h1>
-
-<p>The User Agent Class provides functions that help identify information about the browser, mobile device, or robot visiting your site.
-In addition you can get referrer information as well as language and supported character-set information.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the User Agent class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('user_agent');</code>
-<p>Once loaded, the object will be available using: <dfn>$this->agent</dfn></p>
-
-<h2>User Agent Definitions</h2>
-
-<p>The user agent name definitions are located in a config file located at: <dfn>application/config/user_agents.php</dfn>.  You may add items to the
-various user agent arrays if needed.</p>
-
-<h2>Example</h2>
-
-<p>When the User Agent class is initialized it will attempt to determine whether the user agent browsing your site is
-a web browser, a mobile device, or a robot.  It will also gather the platform information if it is available.</p>
-
-
-<code>
-$this->load->library('user_agent');<br />
-<br />
-if ($this->agent->is_browser())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$agent  = $this->agent->browser().' '.$this->agent->version();<br />
-}<br />
-elseif ($this->agent->is_robot())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$agent = $this->agent->robot();<br />
-}<br />
-elseif ($this->agent->is_mobile())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$agent = $this->agent->mobile();<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$agent = 'Unidentified User Agent';<br />
-}<br />
-<br />
-echo $agent;<br />
-<br />
-echo $this->agent->platform(); // Platform info (Windows, Linux, Mac, etc.)
-</code>
-
-
-<h1>Function Reference</h1>
-
-
-<h2>$this->agent->is_browser()</h2>
-<p>Returns TRUE/FALSE (boolean) if the user agent is a known web browser.</p>
-
-<code> if ($this->agent->is_browser('Safari'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo 'You are using Safari.';<br />
-}<br />
-else if ($this->agent->is_browser())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo 'You are using a browser.';<br />
-}</code>
-
-<p class="important"><strong>Note:</strong>&nbsp; The string "Safari" in this example is an array key in the list of browser definitions.
-You can find this list in <dfn>application/config/user_agents.php</dfn> if you want to add new browsers or change the stings.</p>
-
-<h2>$this->agent->is_mobile()</h2>
-<p>Returns TRUE/FALSE (boolean) if the user agent is a known mobile device.</p>
-
-<code> if ($this->agent->is_mobile('iphone'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('iphone/home');<br />
-}<br />
-else if ($this->agent->is_mobile())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('mobile/home');<br />
-}<br/>
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$this->load->view('web/home');<br />
-}</code>
-
-<h2>$this->agent->is_robot()</h2>
-<p>Returns TRUE/FALSE (boolean) if the user agent is a known robot.</p>
-
-<p class="important"><strong>Note:</strong>&nbsp; The user agent library only contains the most common robot
-definitions.  It is not a complete list of bots. There are hundreds of them so searching for each one would not be
-very efficient. If you find that some bots that commonly visit your site are missing from the list you can add them to your
-<dfn>application/config/user_agents.php</dfn> file.</p>
-
-<h2>$this->agent->is_referral()</h2>
-<p>Returns TRUE/FALSE (boolean) if the user agent was referred from another site.</p>
-
-
-<h2>$this->agent->browser()</h2>
-<p>Returns a string containing the name of the web browser viewing your site.</p>
-
-<h2>$this->agent->version()</h2>
-<p>Returns a string containing the version number of the web browser viewing your site.</p>
-
-<h2>$this->agent->mobile()</h2>
-<p>Returns a string containing the name of the mobile device viewing your site.</p>
-
-<h2>$this->agent->robot()</h2>
-<p>Returns a string containing the name of the robot viewing your site.</p>

-<p>Returns a string containing the platform viewing your site (Linux, Windows, OS X, etc.).</p>
-
-<h2>$this->agent->referrer()</h2>
-<p>The referrer, if the user agent was referred from another site. Typically you'll test for this as follows:</p>

-&nbsp;&nbsp;&nbsp;&nbsp;echo $this->agent->referrer();<br />
-}</code>
-
-
-<h2>$this->agent->agent_string()</h2>

-
-
-<h2>$this->agent->accept_lang()</h2>
-<p>Lets you determine if the user agent accepts a particular language. Example:</p>
-
-<code>if ($this->agent->accept_lang('en'))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo 'You accept English!';<br />
-}</code>
-
-<p class="important"><strong>Note:</strong> This function is not typically very reliable
-since some browsers do not provide language info, and even among those that do, it is not always accurate. </p>

-<h1>XML-RPC and XML-RPC Server Classes</h1>
-
-
-<p>CodeIgniter's XML-RPC classes permit you to send requests to another server, or set up
-your own XML-RPC server to receive requests.</p>
-
-
-<h2>What is XML-RPC?</h2>
-
-<p>Quite simply it is a way for two computers to communicate over the internet using XML.
-One computer, which we will call the <dfn>client</dfn>, sends an XML-RPC <strong>request</strong> to
-another computer, which we will call the <dfn>server</dfn>.  Once the server receives and processes the request it
-will send back a <strong>response</strong> to the client.</p>
-
-<p>For example, using the MetaWeblog API, an XML-RPC Client (usually a desktop publishing tool) will
-send a request to an XML-RPC Server running on your site.  This request might be a new weblog entry
-being sent for publication, or it could be a request for an existing entry for editing.
-
-When the XML-RPC Server receives this request it will examine it to determine which class/method should be called to process the request.
-Once processed, the server will then send back a response message.</p>
-
-<p>For detailed specifications, you can visit the <a href="http://www.xmlrpc.com/">XML-RPC</a> site.</p>
-
-<h2>Initializing the Class</h2>
-
-<p>Like most other classes in CodeIgniter, the XML-RPC and XML-RPCS classes are initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<p>To load the XML-RPC class you will use:</p>
-<code>$this->load->library('xmlrpc');</code>
-<p>Once loaded, the xml-rpc library object will be available using: <dfn>$this->xmlrpc</dfn></p>
-
-<p>To load the XML-RPC Server class you will use:</p>
-<code>
-$this->load->library('xmlrpc');<br />
-$this->load->library('xmlrpcs');
-</code>
-<p>Once loaded, the xml-rpcs library object will be available using: <dfn>$this->xmlrpcs</dfn></p>
-
-<p class="important"><strong>Note:</strong>&nbsp; When using the XML-RPC Server class you must load BOTH the XML-RPC class and the XML-RPC Server class.</p>
-
-
-
-<h2>Sending XML-RPC Requests</h2>
-
-<p>To send a request to an XML-RPC server you must specify the following information:</p>
-
-<ul>
-<li>The URL of the server</li>
-<li>The method on the server you wish to call</li>
-<li>The <em>request</em> data (explained below).</li>
-</ul>
-
-<p>Here is a basic example that sends a simple Weblogs.com ping to the <a href="http://pingomatic.com/">Ping-o-Matic</a></p>
-
-
-<code>$this->load->library('xmlrpc');<br />
-<br />
-$this->xmlrpc->server('http://rpc.pingomatic.com/', 80);<br />
-$this->xmlrpc->method('weblogUpdates.ping');<br />
-
-<br />
-$request = array('My Photoblog', 'http://www.my-site.com/photoblog/');<br />
-$this->xmlrpc->request($request);<br />
-<br />
-if ( ! $this->xmlrpc->send_request())<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;echo $this-&gt;xmlrpc->display_error();<br />
-}</code>
-
-<h3>Explanation</h3>
-
-<p>The above code initializes the XML-RPC class, sets the server URL and method to be called (weblogUpdates.ping).  The
-request (in this case, the title and URL of your site) is placed into an array for transportation, and
-compiled using the request() function.
-Lastly, the full request is sent.  If the <dfn>send_request()</dfn> method returns false we will display the error message
-sent back from the XML-RPC Server.</p>
-
-<h2>Anatomy of a Request</h2>
-
-<p>An XML-RPC <dfn>request</dfn> is simply the data you are sending to the XML-RPC server.  Each piece of data in a request
-is referred to as a <dfn>request parameter</dfn>.  The above example has two parameters:
-The URL and title of your site. When the XML-RPC server receives your request, it will look for parameters it requires.</p>
-
-<p>Request parameters must be placed into an array for transportation, and each parameter can be one
-of seven data types (strings, numbers, dates, etc.). If your parameters are something other than strings
-you will have to include the data type in the request array.</p>
-
-<p>Here is an example of a simple array with three parameters:</p>
-
-<code>$request = array('John', 'Doe', 'www.some-site.com');<br />
-$this->xmlrpc->request($request);</code>
-
-<p>If you use data types other than strings, or if you have several different data types, you will place
-each parameter into its own array, with the data type in the second position:</p>
-
-<code>
-$request = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('John', 'string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('Doe', 'string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(FALSE, 'boolean'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(12345, 'int')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);
-<br />
-$this->xmlrpc->request($request);</code>
-
-The  <a href="#datatypes">Data Types</a>  section below has a full list of data types.
-
-
-
-<h2>Creating an XML-RPC Server</h2>
-
-<p>An XML-RPC Server acts as a traffic cop of sorts, waiting for incoming requests and redirecting them to the
-appropriate functions for processing.</p>
-
-<p>To create your own XML-RPC server involves initializing the XML-RPC Server class in your controller where you expect the incoming
-request to appear, then setting up an array with mapping instructions so that incoming requests can be sent to the appropriate
-class and method for processing.</p>
-
-<p>Here is an example to illustrate:</p>
-
-<code>
-$this->load->library('xmlrpc');<br />
-$this->load->library('xmlrpcs');<br />
-<br />
-$config['functions']['<var>new_post</var>'] = array('function' => '<dfn>My_blog.new_entry</dfn>'),<br />
-$config['functions']['<var>update_post</var>'] = array('function' => '<dfn>My_blog.update_entry</dfn>');<br />
-$config['object'] = $this;<br />
-<br />
-$this->xmlrpcs->initialize($config);<br />
-$this->xmlrpcs->serve();</code>
-
-<p>The above example contains an array specifying two method requests that the Server allows.
-The allowed methods are on the left side of the array. When either of those are received, they will be mapped to the class and method on the right.</p>
-
-<p>The '<var>object</var>' key is a special key that you pass an instantiated class object with, which is necessary when the method you are mapping to is not
-	part of the CodeIgniter super object.</p>
-
-<p>In other words, if an XML-RPC Client sends a request for the <var>new_post</var> method, your
-server will load the <dfn>My_blog</dfn> class and call the <dfn>new_entry</dfn> function.
-If the request is for the <var>update_post</var> method, your
-server will load the <dfn>My_blog</dfn> class and call the <dfn>update_entry</dfn> function.</p>
-
-<p>The function names in the above example are arbitrary.  You'll decide what they should be called on your server,
-or if you are using standardized APIs, like the Blogger or MetaWeblog API, you'll use their function names.</p>
-
-<p>There are two additional configuration keys you may make use of when initializing the server class: <var>debug</var> can be set to TRUE in order to enable debugging, and <var>xss_clean</var> may be set to FALSE to prevent sending data through the Security library's xss_clean function.
-
-<h2>Processing Server Requests</h2>
-
-<p>When the XML-RPC Server receives a request and loads the class/method for processing, it will pass
-an object to that method containing the data sent by the client.</p>
-
-<p>Using the above example, if the <var>new_post</var> method is requested, the server will expect a class
-to exist with this prototype:</p>
-
-<code>class <kbd>My_blog</kbd> extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function <kbd>new_post</kbd>(<var>$request</var>)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-	<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}
-</code>
-
-<p>The <var>$request</var> variable is an object compiled by the Server, which contains the data sent by the XML-RPC Client.
-Using this object you will have access to the <em>request parameters</em> enabling you to process the request.  When
-you are done you will send a <dfn>Response</dfn> back to the Client.</p>
-
-<p>Below is a real-world example, using the Blogger API.  One of the methods in the Blogger API is <dfn>getUserInfo()</dfn>.
-Using this method, an XML-RPC Client can send the Server a username and password, in return the Server sends
-back information about that particular user (nickname, user ID, email address, etc.).  Here is how the processing
-function might look:</p>
-
-
-<code>class <kbd>My_blog</kbd> extends CI_Controller {<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;function <kbd>getUserInfo</kbd>(<var>$request</var>)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$username = 'smitty';<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$password = 'secretsmittypass';<br /><br />
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->load->library('xmlrpc');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$parameters&nbsp;=&nbsp;$request->output_parameters();<br />
-&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if&nbsp;($parameters['1'] != $username AND $parameters['2'] != $password)<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return&nbsp;$this->xmlrpc->send_error_message('100',&nbsp;'Invalid&nbsp;Access');<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-&nbsp;&nbsp;&nbsp;&nbsp;<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$response&nbsp;=&nbsp;array(array('nickname'&nbsp;&nbsp;=>&nbsp;array('Smitty','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'userid'&nbsp;&nbsp;&nbsp;&nbsp;=>&nbsp;array('99','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'url'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=>&nbsp;array('http://yoursite.com','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'email'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=>&nbsp;array('jsmith@yoursite.com','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'lastname'&nbsp;&nbsp;=>&nbsp;array('Smith','string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'firstname'&nbsp;=>&nbsp;array('John','string')<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'struct');<br />
-<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return $this->xmlrpc->send_response($response);<br />
-&nbsp;&nbsp;&nbsp;&nbsp;}<br />
-}
-</code>
-
-<h3>Notes:</h3>
-<p>The <dfn>output_parameters()</dfn> function retrieves an indexed array corresponding to the request parameters sent by the client.
-In the above example, the output parameters will be the username and password.</p>
-
-<p>If the username and password sent by the client were not valid, and error message is returned using <dfn>send_error_message()</dfn>.</p>
-
-<p>If the operation was successful, the client will be sent back a response array containing the user's info.</p>
-
-
-<h2>Formatting a Response</h2>
-
-<p>Similar to <em>Requests</em>, <em>Responses</em> must be formatted as an array.  However, unlike requests, a response is an array
-<strong>that contains a single item</strong>.  This item can be an array with several additional arrays, but there
-can be only one primary array index.  In other words, the basic prototype is this:</p>
-
-<code>$response = array('Response data',  'array');</code>
-
-<p>Responses, however, usually contain multiple pieces of information. In order to accomplish this we must put the response into its own
-array so that the primary array continues to contain a single piece of data.  Here's an example showing how this might be accomplished:</p>
-
-<code>
-$response = array (<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'first_name' => array('John', 'string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'last_name' => array('Doe', 'string'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'member_id' => array(123435, 'int'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'todo_list' => array(array('clean house', 'call mom', 'water plants'), 'array'),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'struct'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);
-</code>
-
-<p class="important">Notice that the above array is formatted as a <dfn>struct</dfn>.  This is the most common data type for responses.</p>
-
-<p>As with Requests, a response can be one of the seven data types listed in the  <a href="#datatypes">Data Types</a>  section.</p>
-
-
-<h2>Sending an Error Response</h2>
-
-<p>If you need to send the client an error response you will use the following:</p>
-
-<code>return $this->xmlrpc->send_error_message('123', 'Requested data not available');</code>
-
-<p>The first parameter is the error number while the second parameter is the error message.</p>
-
-
-
-
-
-
-<h2>Creating Your Own Client and Server</h2>
-
-<p>To help you understand everything we've covered thus far, let's create a couple controllers that act as
-XML-RPC Client and Server.  You'll use the Client to send a request to the Server and receive a response.</p>
-
-<h3>The Client</h3>
-
-<p>Using a text editor, create a controller called <dfn>xmlrpc_client.php</dfn>.
-In it, place this code and save it to your <samp>applications/controllers/</samp> folder:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="32">&lt;?php
-
-class Xmlrpc_client extends CI_Controller {
-
-	function index()
-	{
-		$this->load->helper('url');
-		$server_url = site_url('xmlrpc_server');
-
-		$this->load->library('xmlrpc');
-
-		$this->xmlrpc->server($server_url, 80);
-		$this->xmlrpc->method('Greetings');
-
-		$request = array('How is it going?');
-		$this->xmlrpc->request($request);
-
-		if ( ! $this->xmlrpc->send_request())
-		{
-			echo $this->xmlrpc->display_error();
-		}
-		else
-		{
-			echo '<pre>';
-			print_r($this->xmlrpc->display_response());
-			echo '</pre>';
-		}
-	}
-}
-?></textarea>
-
-<p>Note: In the above code we are using a "url helper".  You can find more information in the <a href="../general/helpers.html">Helpers Functions</a> page.</p>
-
-<h3>The Server</h3>
-
-<p>Using a text editor, create a controller called <dfn>xmlrpc_server.php</dfn>.
-In it, place this code and save it to your <samp>applications/controllers/</samp> folder:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="30">&lt;?php
-
-class Xmlrpc_server extends CI_Controller {
-
-	function index()
-	{
-		$this->load->library('xmlrpc');
-		$this->load->library('xmlrpcs');
-
-		$config['functions']['Greetings'] = array('function' => 'Xmlrpc_server.process');
-
-		$this->xmlrpcs->initialize($config);
-		$this->xmlrpcs->serve();
-	}
-
-
-	function process($request)
-	{
-		$parameters = $request->output_parameters();
-
-		$response = array(
-							array(
-									'you_said'  => $parameters['0'],
-									'i_respond' => 'Not bad at all.'),
-							'struct');
-
-		return $this->xmlrpc->send_response($response);
-	}
-}
-?></textarea>
-
-<h3>Try it!</h3>
-
-<p>Now visit the your site using a URL similar to this:</p>
-<code>example.com/index.php/<var>xmlrpc_client</var>/</code>
-
-<p>You should now see the message you sent to the server, and its response back to you.</p>
-
-<p>The client you created sends a message ("How's is going?") to the server, along with a request for the "Greetings" method.
-The Server receives the request and maps it to the "process" function, where a response is sent back.</p>
-
-<h2>Using Associative Arrays In a Request Parameter</h2>
-
-<p>If you wish to use an associative array in your method parameters you will need to use a struct datatype:</p>
-
-<code>$request = array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array(<br />
-	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Param 0<br />

-<h1>Zip Encoding Class</h1>
-<p>CodeIgniter's Zip Encoding Class classes permit you to create Zip archives. Archives can be downloaded to your
-desktop or saved to a directory.</p>
-
-
-<h2>Initializing the Class</h2>
-<p>Like most other classes in CodeIgniter, the Zip class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('zip');</code>
-<p>Once loaded, the Zip library object will be available using: <dfn>$this->zip</dfn></p>
-
-
-<h2>Usage Example</h2>
-
-<p>This example demonstrates how to compress a file, save it to a folder on your server, and download it to your desktop.</p>
-
-<code>
-$name = 'mydata1.txt';<br />
-$data = 'A Data String!';<br />
-<br />
-$this->zip->add_data($name, $data);<br />
-<br />
-// Write the zip file to a folder on your server. Name it "my_backup.zip"<br />
-$this->zip->archive('/path/to/directory/my_backup.zip');
-<br /><br />
- // Download the file to your desktop.  Name it "my_backup.zip"<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<h1>Function Reference</h1>
-
-<h2>$this->zip->add_data()</h2>
-
-<p>Permits you to add data to the Zip archive. The first parameter must contain the name you would like
-given to the file, the second parameter must contain the file data as a string:</p>
-
-<code>
-$name = 'my_bio.txt';<br />
-$data = 'I was born in an elevator...';<br />
-<br />
-$this->zip->add_data($name, $data);
-</code>
-
-<p>You are allowed multiple calls to this function in order to
-add several files to your archive.  Example:</p>
-
-<code>
-$name = 'mydata1.txt';<br />
-$data = 'A Data String!';<br />
-$this->zip->add_data($name, $data);<br />
-<br />
-$name = 'mydata2.txt';<br />
-$data = 'Another Data String!';<br />
-$this->zip->add_data($name, $data);<br />
-</code>
-
-<p>Or you can pass multiple files using an array:</p>
-
-<code>
-$data = array(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'mydata1.txt' => 'A Data String!',<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'mydata2.txt' => 'Another Data String!'<br />
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
-<br />
-$this->zip->add_data($data);<br />
-<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<p>If you would like your compressed data organized into sub-folders, include the path as part of the filename:</p>
-
-<code>
-$name = '<kbd>personal/</kbd>my_bio.txt';<br />
-$data = 'I was born in an elevator...';<br />
-<br />
-$this->zip->add_data($name, $data);
-</code>
-
-<p>The above example will place <dfn>my_bio.txt</dfn> inside a folder called <kbd>personal</kbd>.</p>
-
-
-<h2>$this->zip->add_dir()</h2>
-
-<p>Permits you to add a directory.  Usually this function is unnecessary since you can place your data into folders when
-using <dfn>$this->zip->add_data()</dfn>, but if you would like to create an empty folder you can do so.  Example:</p>
-
-<code>$this->zip->add_dir('myfolder'); // Creates a folder called "myfolder"</code>
-
-
-
-<h2>$this->zip->read_file()</h2>
-
-<p>Permits you to compress a file that already exists somewhere on your server.  Supply a file path and the zip class will
-read it and add it to the archive:</p>
-
-<code>
-$path = '/path/to/photo.jpg';<br /><br />
-$this->zip->read_file($path);
-<br /><br />
- // Download the file to your desktop.  Name it "my_backup.zip"<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<p>If you would like the Zip archive to maintain the directory structure of the file in it, pass <kbd>TRUE</kbd> (boolean) in the
-second parameter.  Example:</p>
-
-
-<code>
-$path = '/path/to/photo.jpg';<br /><br />
-$this->zip->read_file($path, <kbd>TRUE</kbd>);
-<br /><br />
- // Download the file to your desktop.  Name it "my_backup.zip"<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<p>In the above example, <dfn>photo.jpg</dfn> will be placed inside two folders:  <kbd>path/to/</kbd></p>
-
-
-
-<h2>$this->zip->read_dir()</h2>
-
-<p>Permits you to compress a folder (and its contents) that already exists somewhere on your server.  Supply a file path to the
-directory and the zip class will recursively read it and recreate it as a Zip archive.  All files contained within the
-supplied path will be encoded, as will any sub-folders contained within it.  Example:</p>
-
-<code>
-$path = '/path/to/your/directory/';<br /><br />
-$this->zip->read_dir($path);
-<br /><br />
- // Download the file to your desktop.  Name it "my_backup.zip"<br />
-$this->zip->download('my_backup.zip');
-</code>
-
-<p>By default the Zip archive will place all directories listed in the first parameter inside the zip. If you want the tree preceding the target folder to be ignored
-you can pass <kbd>FALSE</kbd> (boolean) in the second parameter.  Example:</p>
-
-<code>
-$path = '/path/to/your/directory/';<br /><br />
-$this->zip->read_dir($path, FALSE);
-</code>
-
-<p>This will create a ZIP with the folder "directory" inside, then all sub-folders stored correctly inside that, but will not include the folders <samp>/path/to/your</samp>.</p>
-
-
-
-
-<h2>$this->zip->archive()</h2>
-
-<p>Writes the Zip-encoded file to a directory on your server.  Submit a valid server path ending in the file name.  Make sure the
-directory is writable (666 or 777 is usually OK). Example:</p>
-
-<code>$this->zip->archive('/path/to/folder/myarchive.zip'); // Creates a file named myarchive.zip</code>
-
-
-<h2>$this->zip->download()</h2>
-
-<p>Causes the Zip file to be downloaded from your server. The function must be passed the name you would like the zip file called.
-Example:</p>
-
-<code>$this->zip->download('latest_stuff.zip'); // File will be named "latest_stuff.zip"</code>
-
-<p class="important"><strong>Note:</strong>&nbsp; Do not display any data in the controller in which you call this function since it sends various server headers
-that cause the download to happen and the file to be treated as binary.</p>
-
-
-<h2>$this->zip->get_zip()</h2>
-
-<p>Returns the Zip-compressed file data.  Generally you will not need this function unless you want to do something unique with the data.
-Example:</p>
-
-<code>
-$name = 'my_bio.txt';<br />
-$data = 'I was born in an elevator...';<br />
-<br />
-$this->zip->add_data($name, $data);<br /><br />
-
-$zip_file = $this->zip->get_zip();
-</code>
-
-
-<h2>$this->zip->clear_data()</h2>
-
-<p>The Zip class caches your zip data so that it doesn't need to recompile the Zip archive for each function you use above.
-If, however, you need to create multiple Zips, each with different data, you can clear the cache between calls. Example:</p>
-
-<code>
-$name = 'my_bio.txt';<br />
-$data = 'I was born in an elevator...';<br />
-<br />
-$this->zip->add_data($name, $data);<br />
-$zip_file = $this->zip->get_zip();<br />
-<br />
-<kbd>$this->zip->clear_data();</kbd>
-<br /><br />
-
-$name = 'photo.jpg';<br />
-$this->zip->read_file("/path/to/photo.jpg"); // Read the file's contents<br />
-<br /><br />
-$this->zip->download('myphotos.zip');
-</code>

-<li>The Router examines the HTTP request to determine what should be done with it.</li>
-<li>If a cache file exists, it is sent directly to the browser, bypassing the normal system execution.</li>
-<li>Security.  Before the application controller is loaded, the HTTP request and any user submitted data is filtered for security.</li>
-<li>The Controller loads the model, core libraries, helpers, and any other resources needed to process the specific request.</li>
-<li>The finalized View is rendered then sent to the web browser to be seen. If caching is enabled, the view is cached first so
-that on subsequent requests it can be served.</li>

-<h1>CodeIgniter at a Glance</h1>
-
-
-<h2>CodeIgniter is an Application Framework</h2>
-
-<p>CodeIgniter is a toolkit for people who build web applications using PHP.  Its goal is to enable you to develop projects much faster than you could if you were writing code
-from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and
-logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by
-minimizing the amount of code needed for a given task.</p>
-
-<h2>CodeIgniter is Free</h2>
-<p>CodeIgniter is licensed under an Apache/BSD-style open source license so you can use it however you please.
-For more information please read the <a href="../license.html">license agreement</a>.</p>
-
-<h2>CodeIgniter is Light Weight</h2>
-<p>Truly light weight.  The core system requires only a few very small libraries. This is in stark contrast to many frameworks that require significantly more resources.
-Additional libraries are loaded dynamically upon request, based on your needs for a given process, so the base system
-is very lean and quite fast.
-</p>
-
-<h2>CodeIgniter is Fast</h2>
-<p>Really fast. We challenge you to find a framework that has better performance than CodeIgniter.</p>
-
-
-<h2>CodeIgniter Uses M-V-C</h2>
-<p>CodeIgniter uses the Model-View-Controller approach, which allows great separation between logic and presentation.
-This is particularly good for projects in which designers are working with your template files, as the code these file contain will be minimized. We describe MVC in more detail on its own page.</p>
-
-<h2>CodeIgniter Generates Clean URLs</h2>
-<p>The URLs generated by CodeIgniter are clean and search-engine friendly.  Rather than using the standard "query string"
-approach to URLs that is synonymous with dynamic systems, CodeIgniter uses a segment-based approach:</p>
-
-<code>example.com/<var>news</var>/<dfn>article</dfn>/<samp>345</samp></code>
-
-<p>Note: By default the index.php file is included in the URL but it can be removed using a simple .htaccess file.</p>
-
-<h2>CodeIgniter Packs a Punch</h2>
-<p>CodeIgniter comes with  full-range of libraries that enable the most commonly needed web development tasks,
-like accessing a database, sending email, validating form data, maintaining sessions, manipulating images, working with XML-RPC data and
-much more.</p>
-
-<h2>CodeIgniter is Extensible</h2>
-<p>The system can be easily extended through the use of your own libraries, helpers, or through class extensions or system hooks.</p>
-
-
-<h2>CodeIgniter Does Not Require a Template Engine</h2>
-<p>Although CodeIgniter <em>does</em> come with a simple template parser that can be optionally used, it does not force you to use one.
-
-Template engines simply can not match the performance of native PHP, and the syntax that must be learned to use a template
-engine is usually only marginally easier than learning the basics of PHP.  Consider this block of PHP code:</p>
-
-<code>&lt;ul><br />
-<br />
-&lt;?php foreach ($addressbook as $name):?><br />
-<br />
-&lt;li>&lt;?=$name?>&lt;/li><br />
-<br />
-&lt;?php endforeach; ?><br />
-<br />
-&lt;/ul></code>
-
-<p>Contrast this with the pseudo-code used by a template engine:</p>
-
-<code>&lt;ul><br />
-<br />
-{foreach from=$addressbook item="name"}<br />
-<br />
-&lt;li>{$name}&lt;/li><br />
-<br />
-{/foreach}<br />
-<br />
-&lt;/ul></code>
-
-<p>Yes, the template engine example is a bit cleaner, but it comes at the price of performance, as the pseudo-code must be converted
-back into PHP to run. Since one of our goals is <em>maximum performance</em>, we opted to not require the use of a template engine.</p>
-
-
-<h2>CodeIgniter is Thoroughly Documented</h2>
-<p>Programmers love to code and hate to write documentation.  We're no different, of course, but
-since documentation is <strong>as important</strong> as the code itself,
-we are committed to doing it. Our source code is extremely clean and well commented as well.</p>
-
-
-<h2>CodeIgniter has a Friendly Community of Users</h2>
-
-<p>Our growing community of users can be seen actively participating in our <a href="http://codeigniter.com/forums/">Community Forums</a>.</p>

-<h1>CodeIgniter Features</h1>
-
-<p>Features in and of themselves are a very poor way to judge an application since they tell you nothing
-about the user experience, or how intuitively or intelligently it is designed.  Features
-don't reveal anything about the quality of the code, or the performance, or the attention to detail, or security practices.
-The only way to really judge an app is to try it and get to know the code. <a href="../installation/">Installing</a>
-CodeIgniter is child's play so we encourage you to do just that.  In the mean time here's a list of CodeIgniter's main features.</p>
-
-<ul>
-<li>Model-View-Controller Based System</li>
-<li>Extremely Light Weight</li>
-<li>Full Featured database classes with support for several platforms.</li>
-<li>Active Record Database Support</li>
-<li>Form and Data Validation</li>
-<li>Security and XSS Filtering</li>
-<li>Session Management</li>
-<li>Email Sending Class. Supports Attachments, HTML/Text email, multiple protocols (sendmail, SMTP, and Mail) and more.</li>
-<li>Image Manipulation Library (cropping, resizing, rotating, etc.).  Supports GD, ImageMagick, and NetPBM</li>
-<li>File Uploading Class</li>
-<li>FTP Class</li>
-<li>Localization</li>
-<li>Pagination</li>
-<li>Data Encryption</li>
-<li>Benchmarking</li>
-<li>Full Page Caching</li>
-<li>Error Logging</li>
-<li>Application Profiling</li>
-<li>Calendaring Class</li>
-<li>User Agent Class</li>

-<h2>Design and Architectural Goals</h2>
-
-<p>Our goal for CodeIgniter is <dfn>maximum performance, capability, and flexibility in the smallest, lightest possible package</dfn>.</p>
-
-<p>To meet this goal we are committed to benchmarking, re-factoring, and simplifying at every step of the development process,
-rejecting anything that doesn't further the stated objective.</p>
-
-<p>From a technical and architectural standpoint, CodeIgniter was created with the following objectives:</p>
-
-<ul>
-<li><strong>Dynamic Instantiation.</strong>  In CodeIgniter, components are loaded and routines executed only when requested, rather than globally.  No assumptions are made by the system regarding what may be needed beyond the minimal core resources, so the system is very light-weight by default.  The events, as triggered by the HTTP request, and the controllers and views you design will determine what is invoked.</li>
-<li><strong>Loose Coupling.</strong>  Coupling is the degree to which components of a system rely on each other.  The less components depend on each other the more reusable and flexible the system becomes. Our goal was a very loosely coupled system.</li>
-<li><strong>Component Singularity.</strong>  Singularity is the degree to which components have a narrowly focused purpose.  In CodeIgniter, each class and its functions are highly autonomous in order to allow maximum usefulness.</li>
-</ul>
-
-<p>CodeIgniter is a dynamically instantiated, loosely coupled system with high component singularity. It strives for simplicity, flexibility, and high performance in a small footprint package.</p>

-<h1>Model-View-Controller</h1>
-
-<p>CodeIgniter is based on the Model-View-Controller development pattern.
-
-MVC is a software approach that separates application logic from presentation.  In practice, it permits your web pages to contain minimal scripting since the presentation is separate from the PHP scripting.</p>
-
-<ul>
-<li>The <strong>Model</strong> represents your data structures. Typically your model classes will contain functions that help you
-retrieve, insert, and update information in your  database.</li>
-<li>The <strong>View</strong> is the information that is being presented to a user.  A View will normally be a web page, but
-in CodeIgniter, a view can also be a page fragment like a header or footer. It can also be an RSS page, or any other type of "page".</li>
-<li>The <strong>Controller</strong> serves as an <em>intermediary</em> between the Model, the View,
-and any other resources needed to process the HTTP request and generate a web page.</li>
-
-</ul>
-
-<p>CodeIgniter has a fairly loose approach to MVC since Models are not required.
-If you don't need the added separation, or find that maintaining models requires more complexity than you
-want, you can ignore them and build your application minimally using Controllers and Views. CodeIgniter also
-enables you to incorporate your own existing scripts, or even develop core libraries for the system,
- enabling you to work in a way that makes the most sense to you.</p>

-<h1>Tutorial - Conclusion</h1>
-
-<p>This tutorial did not cover all of the things you might expect of a full-fledged content management system, but it introduced you to the more important topics of routing, writing controllers, and models. We hope this tutorial gave you an insight into some of CodeIgniter's basic design patterns, which you can expand upon.</p>
-
-<p>Now that you've completed this tutorial, we recommend you check out the rest of the documentation. CodeIgniter is often praised because of its comprehensive documentation. Use this to your advantage and read the "Introduction" and "General Topics" sections thoroughly. You should read the class and helper references when needed.</p>
-
-<p>Every intermediate PHP programmer should be able to get the hang of CodeIgniter within a few days.</p>
-
-<p>If you still have questions about the framework or your own CodeIgniter code, you can:</p>

-<h1>Tutorial - Create news items</h1>
-
-<p>You now know how you can read data from a database using CodeIgnite, but you haven't written any information to the database yet. In this section you'll expand your news controller and model created earlier to include this functionality.</p>
-
-<h2>Create a form</h2>
-
-<p>To input data into the database you need to create a form where you can input the information to be stored. This means you'll be needing a form with two fields, one for the title and one for the text. You'll derive the slug from our title in the model. Create the new view at <dfn>application/views/news/create.php</dfn>.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="16">
-<h2>Create a news item</h2>
-
-&lt;?php echo validation_errors(); ?>
-
-&lt;?php echo form_open('news/create') ?>
-
-	<label for="title">Title</label> 
-	<input type="input" name="title" /><br />
-
-	<label for="text">Text</label>
-	<textarea name="text">&lt;/textarea><br />
-	
-	<input type="submit" name="submit" value="Create news item" /> 
-
-&lt;/form>
-</textarea>
-
-<p>There are only two things here that probably look unfamiliar to you: the <dfn>form_open()</dfn> function and the <dfn>validation_errors()</dfn> function.</p>
-
-<p>The first function is provided by the <a href="../helpers/form_helper.html">form helper</a> and renders the form element and adds extra functionality, like adding a hidden <a href="../libraries/security.html">CSFR prevention field</a>. The latter is used to report errors related to form validation.</p>
-
-<p>Go back to your news controller. You're going to do two things here, check whether the form was submitted and whether the submitted data passed the validation rules. You'll use the <a href="../libraries/form_validation.html">form validation</a> library to do this.</p>
-
-<pre>
-public function create()
-{
-	$this->load->helper('form');
-	$this->load->library('form_validation');
-	
-	$data['title'] = 'Create a news item';
-	
-	$this->form_validation->set_rules('title', 'Title', 'required');
-	$this->form_validation->set_rules('text', 'text', 'required');
-	
-	if ($this->form_validation->run() === FALSE)
-	{
-		$this->load->view('templates/header', $data);	
-		$this->load->view('news/create');
-		$this->load->view('templates/footer');
-		
-	}
-	else
-	{
-		$this->news_model->set_news();
-		$this->load->view('news/success');
-	}
-}
-</pre>
-
-<p>The code above adds a lot of functionality. The first few lines load the form helper and the form validation library. After that, rules for the form validation are set. The <var>set_rules()</var> method takes three arguments; the name of the input field, the name to be used in error messages, and the rule. In this case the title and text fields are required.</p>
-
-<p>CodeIgniter has a powerful form validation library as demonstrated above. You can read <a href="../libraries/form_validation.html">more about this library here</a>.</p>
-
-<p>Continuing down, you can see a condition that checks whether the form validation ran successfully. If it did not, the form is displayed, if it was submitted <strong>and</strong> passed all the rules, the model is called. After this, a view is loaded to display a success message. Create a view at <dfn>application/view/news/success.php</dfn> and write a success message.</p>
-
-<h2>Model</h2>
-
-<p>The only thing that remains is writing a method that writes the data to the database. You'll use the Active Record class to insert the information and use the input library to get the posted data. Open up the model created earlier and add the following:</p>
-
-<pre>
-public function set_news()
-{
-	$this->load->helper('url');
-	
-	$slug = url_title($this->input->post('title'), 'dash', TRUE);
-	
-	$data = array(
-		'title' => $this->input->post('title'),
-		'slug' => $slug,
-		'text' => $this->input->post('text')
-	);
-	
-	return $this->db->insert('news', $data);
-}
-</pre>
-
-<p>This new method takes care of inserting the news item into the database. The third line contains a new function, <dfn>url_title()</dfn>. This function - provided by the <a href="../helpers/url_helper.html">URL helper</a> - strips down the string you pass it, replacing all spaces by dashes (-) and makes sure everything is in lowercase characters. This leaves you with a nice slug, perfect for creating URIs.</p>
-	
-<p>Let's continue with preparing the record that is going to be inserted later, inside the <var>$data</var> array. Each element corresponds with a column in the database table created earlier. You might notice a new method here, namely the <dfn>post()</dfn> method from the <a href="../libraries/input.html">input library</a>. This method makes sure the data is sanitized, protecting you from nasty attacks from others. The input library is loaded by default. At last, you insert our <var>$data</var> array into our database.</p>
-
-<h2>Routing</h2>
-
-<p>Before you can start adding news items into your CodeIgniter application you have to add an extra rule to <dfn>config/routes.php</dfn> file. Make sure your file contains the following. This makes sure CodeIgniter sees 'create' as a method instead of a news item's slug.</p>
-	
-<pre>
-$route['news/create'] = 'news/create';
-$route['news/(:any)'] = 'news/view/$1';
-$route['news'] = 'news';
-$route['(:any)'] = 'pages/view/$1';
-$route['default_controller'] = 'pages/view';
-</pre>
-
-<p>Now point your browser to your local development environment where you installed CodeIgniter and add <dfn>index.php/news/create</dfn> to the URL. Congratulations, you just created your first CodeIgniter application! Add some news and check out the different pages you made.</p>

-<h1>Tutorial - Hard coded pages</h1>
-
-<p>The first thing we're going to do is setting up a controller to handle our hard coded pages. A controller is a class with a collection of methods that represent the different actions you can perform on a certain object. In our case, we want to be able to view a page.</p>
-
-<p class="important"><strong>Note:</strong> This tutorial assumes you've downloaded CodeIgniter and installed the framework in your development environment.</p>
-
-<p>Create a file at <dfn>application/controllers/pages.php</dfn> with the following code.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="9">
-&lt;?php
-class Pages extends CI_Controller {
-
-	public function view($page = 'home')
-	{
-
-	}
-}
-</textarea>
-
-<p>If you're familiar with PHP classes you see that we create a Pages class with a view method that accepts one parameter, <var>$page</var>. Another interesting observation is that the Pages class is extending the CI_Controller class. This means that the new Pages class can access the methods and variables defined in the CI_Controller class. When you look at this class in <dfn>system/core/controller.php</dfn> you can see this class is doing something really important; assigning an instance from the CodeIgniter super object to the <var>$this</var> object. In most of your code, <var>$this</var> is the object you will use to interact with the framework.</p>
-
-<p>Now we've created our first method, it is time to do some basic templating. For this tutorial, we will be creating two views to acts as our footer and header. Let's create our header at <dfn>application/views/templates/header.php</dfn> and ad the following code.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="8">
-<html>
-<head>
-	<title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
-</head>
-<body>
-	<h1>CodeIgniter 2 Tutorial</h1>
-	
-</textarea>
-
-<p>Our header doesn't do anything exciting. It contains the basic HTML code that we will want to display before loading the main view. You can also see that we echo the <var>$title</var> variable, which we didn't define. We will set this variable in the Pages controller a bit later. Let's go ahead and create a footer at <dfn>application/views/templates/footer.php</dfn> that includes the following code.</p>
-	
-<textarea class="textarea" style="width:100%" cols="50" rows="4">
-<strong>&copy; 2011</strong>	
-</body>
-</html>
-</textarea>
-
-<h2>Adding logic to the controller</h2>
-
-<p>Now we've set up the basics so we can finally do some real programming. Earlier we set up our controller with a view method. Because we don't want to write a separate method for every page, we made the view method accept one parameter, the name of the page. These hard coded pages will be located in <dfn>application/views/pages/</dfn>. Create two files in this directory named <dfn>home.php</dfn> and <dfn>about.php</dfn> and put in some HTML content.</p>
-
-<p>In order to load these pages we'll have to check whether these page actually exists. When the page does exist, we load the view for that pages, including the header and footer and display it to the user. If it doesn't, we show a "404 Page not found" error.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="16">
-public function view($page = 'home')
-{
-			
-	if ( ! file_exists('application/views/pages/' . $page . EXT))
-	{
-		show_404();
-	}
-	
-	$data['title'] = ucfirst($page);
-	
-	$this->load->view('templates/header', $data);
-	$this->load->view('pages/'.$page);
-	$this->load->view('templates/footer');
-}	
-</textarea>
-
-<p>The first thing we do is checking whether the page we're looking for does actually exist. We use PHP's native file_exists() to do this check and pass the path where the file is supposed to be. Next is the function show_404(), a CodeIgniter function that renders the default error page and sets the appropriate HTTP headers.</p>
-
-<p>In the header template you saw we were using the <var>$title</var> variable to customize our page title. This is where we define the title, but instead of assigning the value to a variable, we assign it to the title element in the <var>$data</var> array. The last thing we need to do is loading the views in the order we want them to be displayed. We also pass the <var>$data</var> array to the header view to make its elements available in the header view file.<p> 
-	
-<h2>Routing</h2>
-
-<p>Actually, our controller is already functioning. Point your browser to <dfn>index.php/pages/view</dfn> to see your homepage. When you visit <dfn>index.php/pages/view/about</dfn> you will see the about page, again including your header and footer. Now we're going to get rid of the pages/view part in our URI. As you may have seen, CodeIgniter does its routing by the class, method and parameter, separated by slashes.</p>
-
-<p>Open the routing file located at <dfn>application/config/routes.php</dfn> and add the following two lines. Remove all other code that sets any element in the <var>$route</var> array.</p>
-	
-<textarea class="textarea" style="width:100%" cols="50" rows="3">
-$route['(:any)'] = 'pages/view/$1';
-$route['default_controller'] = 'pages/view';
-</textarea>
-
-<p>CodeIgniter reads its routing rules from top to bottom and routes the request to the first matching rule. These routes are stored in the <var>$route</var> array where the keys represent the incoming request and the value the path to the method, as described above.</p> 
-
-<p>The first rule in our <var>$routes</var> array matches every request - using the wildcard operator <dfn>(:any)</dfn> - and passes the value to the view method of the pages class we created earlier. The default controller route makes sure every request to the root goes to the view method as well, which has the first parameter set to 'home' by default.</p>

-<h1>Tutorial &minus; News section</h1>
-
-<p>In the last section, we went over some basic concepts of the framework by writing a class that includes static pages. We cleaned up the URI by adding custom routing rules. Now it's time to introduce dynamic content and start using a database.</p>
-
-<h2>Setting up your model</h2>
-
-<p>Instead of writing database operations right in the controller, queries should be placed in a model, so they can easily be reused later. Models are the place where you retrieve, insert, and update information in your database or other data stores. They represent your data.</p>
-
-<p>Open up the <dfn>application/models</dfn> directory and create a new file called <dfn>news_model.php</dfn> and add the following code. Make sure you've configured your database properly as described <a href="../database/configuration.html">here</a>.</p>
-
-<pre>
-&lt;?php
-class News_model extends CI_Model {
-
-	public function __construct()
-	{
-		$this->load->database();
-	}
-}
-</pre>
-
-<p>This code looks similar to the controller code that was used earlier. It creates a new model by extending CI_Model and loads the database library. This will make the database class available through the <var>$this->db</var> object.</p>
-
-<p>Before querying the database, a database schema has to be created. Connect to your database and run the SQL command below. Also add some seed records.</p>
-
-<pre>
-CREATE TABLE news (
-	id int(11) NOT NULL AUTO_INCREMENT,
-	title varchar(128) NOT NULL,
-	slug varchar(128) NOT NULL,
-	text text NOT NULL,
-	PRIMARY KEY (id),
-	KEY slug (slug)
-);
-</pre>
-
-<p>Now that the database and a model have been set up, you'll need a method to get all of our posts from our database. To do this, the database abstraction layer that is included with CodeIgniter — <a href="../database/active_record.html">Active Record</a> — is used. This makes it possible to write your 'queries' once and make them work on <a href="../general/requirements.html">all supported database systems</a>. Add the following code to your model.</p>
-
-<pre>
-public function get_news($slug = FALSE)
-{
-	if ($slug === FALSE)
-	{
-		$query = $this->db->get('news');
-		return $query->result_array();
-	}
-	
-	$query = $this->db->get_where('news', array('slug' => $slug));
-	return $query->row_array();
-}
-</pre>
-
-<p>With this code you can perform two different queries. You can get all news records, or get a news item by its <a href="#" title="a URL friendly version of a string">slug</a>. You might have noticed that the <var>$slug</var> variable wasn't sanitized before running the query; Active Record does this for you.</p>
-
-<h2>Display the news</h2>
-
-<p>Now that the queries are written, the model should be tied to the views that are going to display the news items to the user. This could be done in our pages controller created earlier, but for the sake of clarity, a new "news" controller is defined. Create the new controller at <dfn>application/controllers/news.php</dfn>.</p>
-
-<pre>
-&lt;?php
-class News extends CI_Controller {
-
-	public function __construct()
-	{
-		parent::__construct();
-		$this->load->model('news_model');
-	}
-
-	public function index()
-	{
-		$data['news'] = $this->news_model->get_news();
-	}
-
-	public function view($slug)
-	{
-		$data['news'] = $this->news_model->get_news($slug);
-	}
-}
-</pre>
-
-<p>Looking at the code, you may see some similarity with the files we created earlier. First, the "__construct" method: it calls the constructor of its parent class (<dfn>CI_Controller</dfn>) and loads the model, so it can be used in all other methods in this controller.</p>
-
-<p>Next, there are two methods to view all news items and one for a specific news item. You can see that the <var>$slug</var> variable is passed to the model's method in the second method. The model is using this slug to identify the news item to be returned.</p>
-
-<p>Now the data is retrieved by the controller through our model, but nothing is displayed yet. The next thing to do is passing this data to the views.</p>
-
-<pre>
-public function index()
-{
-	$data['news'] = $this->news_model->get_news();
-	$data['title'] = 'News archive';
-
-	$this->load->view('templates/header', $data);
-	$this->load->view('news/index', $data);
-	$this->load->view('templates/footer');
-}
-</pre>
-
-<p>The code above gets all news records from the model and assigns it to a variable. The value for the title is also assigned to the <var>$data['title']</var> element and all data is passed to the views. You now need to create a view to render the news items. Create <dfn>application/views/news/index.php</dfn> and add the next piece of code.</p>
-
-<pre>
-&lt;?php foreach ($news as $news_item): ?&gt;
-
-    &lt;h2&gt;&lt;?php echo $news_item['title'] ?&gt;&lt;/h2&gt;
-    &lt;div id="main"&gt;
-        &lt;?php echo $news_item['text'] ?&gt;
-    &lt;/div&gt;
-    &lt;p&gt;&lt;a href="news/&lt;?php echo $news_item['slug'] ?&gt;"&gt;View article&lt;/a&gt;&lt;/p&gt;
-
-&lt;?php endforeach ?&gt;
-</pre>
-
-<p>Here, each news item is looped and displayed to the user. You can see we wrote our template in PHP mixed with HTML. If you prefer to use a template language, you can use CodeIgniter's <a href="../libraries/parser.html">Template Parser</a> class or a third party parser.</p>
-
-<p>The news overview page is now done, but a page to display individual news items is still absent. The model created earlier is made in such way that it can easily be used for this functionality. You only need to add some code to the controller and create a new view. Go back to the news controller and add the following lines to the file.</p>
-
-<pre>
-public function view($slug)
-{
-	$data['news_item'] = $this->news_model->get_news($slug);
-
-	if (empty($data['news_item']))
-	{
-		show_404();
-	}
-
-	$data['title'] = $data['news_item']['title'];
-
-	$this->load->view('templates/header', $data);
-	$this->load->view('news/view', $data);
-	$this->load->view('templates/footer');
-}
-</pre>
-
-<p>Instead of calling the <var>get_news()</var> method without a parameter, the <var>$slug</var> variable is passed, so it will return the specific news item. The only things left to do is create the corresponding view at <dfn>application/views/news/view.php</dfn>. Put the following code in this file.</p>
-
-<pre>
-&lt;?php
-echo '&lt;h2&gt;'.$news_item['title'].'&lt;/h2&gt;';
-echo $news_item['text'];
-</pre>
-
-<h2>Routing</h2>
-<p>Because of the wildcard routing rule created earlier, you need need an extra route to view the controller that you just made. Modify your routing file (<dfn>application/config/routes.php</dfn>) so it looks as follows. This makes sure the requests reaches the news controller instead of going directly to the pages controller. The first line routes URI's with a slug to the view method in the news controller.</p>
-
-<pre>
-$route['news/(:any)'] = 'news/view/$1';
-$route['news'] = 'news';
-$route['(:any)'] = 'pages/view/$1';
-$route['default_controller'] = 'pages/view';
-</pre>
-
-<p>Point your browser to your document root, followed by <dfn>index.php/news</dfn> and watch your news page.</p>

-<h1>Tutorial &minus; Static pages</h1>
-
-<p class="important"><strong>Note:</strong> This tutorial assumes you've downloaded CodeIgniter and <a href="../installation/index.html">installed the framework</a> in your development environment.</p>
-
-<p>The first thing you're going to do is set up a <strong>controller</strong> to handle static pages.
-A controller is simply a class that helps delegate work. It is the glue of your
-web application.</p>
-
-<p>For example, when a call is made to: <code>http://example.com/news/latest/10</code> We might imagine
-that there is a controller named &quot;news&quot;. The method being called on news
-would be &quot;latest&quot;. The news method's job could be to grab 10
-news items, and render them on the page. Very often in MVC, you'll see URL
-patterns that match: <code>http://example.com/[controller-class]/[controller-method]/[arguments]</code>
-As URL schemes become more complex, this may change. But for now, this is all we will need to know.</p>
-
-<p>Create a file at <dfn>application/controllers/pages.php</dfn> with the following code.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;?php
-
-class Pages extends CI_Controller {
-
-	public function view($page = 'home')
-	{
-
-	}
-}
-</textarea>
-
-<p>You have created a class named &quot;pages&quot;, with a view method that accepts one argument named <var>$page</var>.
-The pages class is extending the CI_Controller class.
-This means that the new pages class can access the methods and variables defined in the CI_Controller class
-(<dfn>system/core/Controller.php</dfn>).</p>
-
-<p>The <strong>controller is what will become the center of every request</strong> to your web application.
-In very technical CodeIgniter discussions, it may be referred to as the <em>super object</em>.
-Like any php class, you refer to it within your controllers as <var>$this</var>.
-Referring to <var>$this</var> is how you will load libraries, views, and generally
-command the framework.</p>
-
-<p>Now you've created your first method, it's time to make some basic page templates.
-We will be creating two &quot;views&quot; (page templates) that act as our page footer and header.</p>
-
-<p>Create the header at <dfn>application/views/templates/header.php</dfn> and add the following code.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="8">
-<html>
-<head>
-	<title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
-</head>
-<body>
-	<h1>CodeIgniter 2 Tutorial</h1>
-	
-</textarea>
-
-<p>The header contains the basic HTML code that you'll want to display before loading the main view, together with a heading. 
-It will also output the <var>$title</var> variable, which we'll define later in the controller.
-Now create a footer at <dfn>application/views/templates/footer.php</dfn> that includes the following code:</p>
-	
-<textarea class="textarea" style="width:100%" cols="50" rows="4">
-<strong>&#38;copy; 2011</strong>	
-</body>
-</html>
-</textarea>
-
-<h2>Adding logic to the controller</h2>
-
-<p>Earlier you set up a controller with a view() method. The method accepts one parameter, which is the name of the page to be loaded.
-The static page templates will be located in the <dfn>application/views/pages/</dfn> directory.</p>
-
-<p>In that directory, create two files named <dfn>home.php</dfn> and <dfn>about.php</dfn>. 
-Within those files, type some text &minus; anything you'd like &minus; and save them. 
-If you like to be particularly un-original, try &quot;Hello World!&quot;.</p>
-
-<p>In order to load those pages, you'll have to check whether the requested page actually exists:</p>
-
-<pre>
-public function view($page = 'home')
-{
-			
-	if ( ! file_exists('application/views/pages/'.$page.'.php'))
-	{
-		// Whoops, we don't have a page for that!
-		show_404();
-	}
-	
-	$data['title'] = ucfirst($page); // Capitalize the first letter
-	
-	$this->load->view('templates/header', $data);
-	$this->load->view('pages/'.$page, $data);
-	$this->load->view('templates/footer', $data);
-
-}
-</pre>
-
-<p>Now, when the page does exist, it is loaded, including the header and footer, and displayed to the user. If the page doesn't exist, a "404 Page not found" error is shown.</p>
-
-<p>The first line in this method checks whether the page actually exists. PHP's native <var>file_exists()</var> function is used to check whether the file is where it's expected to be. <var>show_404()</var> is a built-in CodeIgniter function that renders the default error page.</p>
-
-<p>In the header template, the <var>$title</var> variable was used to customize the page title. The value of title is defined in this method, but instead of assigning the value to a variable, it is assigned to the title element in the <var>$data</var> array.</p>
-
-<p>The last thing that has to be done is loading the views in the order they should be displayed.
-The second parameter in the <var>view()</var> method is used to pass values to the view. Each value in the <var>$data</var> array is assigned to a variable with the name of its key. So the value of <var>$data['title']</var> in the controller is equivalent to $title in the view.<p>
-	
-<h2>Routing</h2>
-
-<p>The controller is now functioning! Point your browser to <dfn>[your-site-url]index.php/pages/view</dfn> to see your page. When you visit <dfn>index.php/pages/view/about</dfn> you'll see the about page, again including the header and footer.</p>
-
-<p>Using custom routing rules, you have the power to map any URI to any controller and method, and break free from the normal convention:
-<code>http://example.com/[controller-class]/[controller-method]/[arguments]</code></p>
-
-<p>Let's do that. Open the routing file located at <dfn>application/config/routes.php</dfn> and add the following two lines. Remove all other code that sets any element in the <var>$route</var> array.</p>
-	
-<pre>
-$route['default_controller'] = 'pages/view';
-$route['(:any)'] = 'pages/view/$1';
-</pre>
-
-<p>CodeIgniter reads its routing rules from top to bottom and routes the request to the first matching rule. Each rule is a regular expression
-(left-side) mapped to a controller and method name separated by slashes (right-side).
-When a request comes in, CodeIgniter looks for the first match, and calls the appropriate controller and method, possibly with arguments.</p>
-
-<p>More information about routing can be found in the URI Routing <a href="../general/routing.html">documentation</a>.</p>
-
-<p>Here, the second rule in the <var>$routes</var> array matches <strong>any</strong> request using the wildcard string <dfn>(:any)</dfn>.
-and passes the parameter to the view() method of the pages class.</p>
-
-<p>Now visit <dfn>index.php/about</dfn>. Did it get routed correctly to the <var>view()</var> method
-in the pages controller? Awesome!</p>

+<h1>Tutorial - Conclusion</h1>
+
+<p>This tutorial did not cover all of the things you might expect of a full-fledged content management system, but it introduced you to the more important topics of routing, writing controllers, and models. We hope this tutorial gave you an insight into some of CodeIgniter's basic design patterns, which you can expand upon.</p>
+
+<p>Now that you've completed this tutorial, we recommend you check out the rest of the documentation. CodeIgniter is often praised because of its comprehensive documentation. Use this to your advantage and read the "Introduction" and "General Topics" sections thoroughly. You should read the class and helper references when needed.</p>
+
+<p>Every intermediate PHP programmer should be able to get the hang of CodeIgniter within a few days.</p>
+
+<p>If you still have questions about the framework or your own CodeIgniter code, you can:</p>

+<h1>Tutorial - Create news items</h1>
+
+<p>You now know how you can read data from a database using CodeIgnite, but you haven't written any information to the database yet. In this section you'll expand your news controller and model created earlier to include this functionality.</p>
+
+<h2>Create a form</h2>
+
+<p>To input data into the database you need to create a form where you can input the information to be stored. This means you'll be needing a form with two fields, one for the title and one for the text. You'll derive the slug from our title in the model. Create the new view at <dfn>application/views/news/create.php</dfn>.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="16">
+<h2>Create a news item</h2>
+
+&lt;?php echo validation_errors(); ?>
+
+&lt;?php echo form_open('news/create') ?>
+
+	<label for="title">Title</label> 
+	<input type="input" name="title" /><br />
+
+	<label for="text">Text</label>
+	<textarea name="text">&lt;/textarea><br />
+	
+	<input type="submit" name="submit" value="Create news item" /> 
+
+&lt;/form>
+</textarea>
+
+<p>There are only two things here that probably look unfamiliar to you: the <dfn>form_open()</dfn> function and the <dfn>validation_errors()</dfn> function.</p>
+
+<p>The first function is provided by the <a href="../helpers/form_helper.html">form helper</a> and renders the form element and adds extra functionality, like adding a hidden <a href="../libraries/security.html">CSFR prevention field</a>. The latter is used to report errors related to form validation.</p>
+
+<p>Go back to your news controller. You're going to do two things here, check whether the form was submitted and whether the submitted data passed the validation rules. You'll use the <a href="../libraries/form_validation.html">form validation</a> library to do this.</p>
+
+<pre>
+public function create()
+{
+	$this->load->helper('form');
+	$this->load->library('form_validation');
+	
+	$data['title'] = 'Create a news item';
+	
+	$this->form_validation->set_rules('title', 'Title', 'required');
+	$this->form_validation->set_rules('text', 'text', 'required');
+	
+	if ($this->form_validation->run() === FALSE)
+	{
+		$this->load->view('templates/header', $data);	
+		$this->load->view('news/create');
+		$this->load->view('templates/footer');
+		
+	}
+	else
+	{
+		$this->news_model->set_news();
+		$this->load->view('news/success');
+	}
+}
+</pre>
+
+<p>The code above adds a lot of functionality. The first few lines load the form helper and the form validation library. After that, rules for the form validation are set. The <var>set_rules()</var> method takes three arguments; the name of the input field, the name to be used in error messages, and the rule. In this case the title and text fields are required.</p>
+
+<p>CodeIgniter has a powerful form validation library as demonstrated above. You can read <a href="../libraries/form_validation.html">more about this library here</a>.</p>
+
+<p>Continuing down, you can see a condition that checks whether the form validation ran successfully. If it did not, the form is displayed, if it was submitted <strong>and</strong> passed all the rules, the model is called. After this, a view is loaded to display a success message. Create a view at <dfn>application/view/news/success.php</dfn> and write a success message.</p>
+
+<h2>Model</h2>
+
+<p>The only thing that remains is writing a method that writes the data to the database. You'll use the Active Record class to insert the information and use the input library to get the posted data. Open up the model created earlier and add the following:</p>
+
+<pre>
+public function set_news()
+{
+	$this->load->helper('url');
+	
+	$slug = url_title($this->input->post('title'), 'dash', TRUE);
+	
+	$data = array(
+		'title' => $this->input->post('title'),
+		'slug' => $slug,
+		'text' => $this->input->post('text')
+	);
+	
+	return $this->db->insert('news', $data);
+}
+</pre>
+
+<p>This new method takes care of inserting the news item into the database. The third line contains a new function, <dfn>url_title()</dfn>. This function - provided by the <a href="../helpers/url_helper.html">URL helper</a> - strips down the string you pass it, replacing all spaces by dashes (-) and makes sure everything is in lowercase characters. This leaves you with a nice slug, perfect for creating URIs.</p>
+	
+<p>Let's continue with preparing the record that is going to be inserted later, inside the <var>$data</var> array. Each element corresponds with a column in the database table created earlier. You might notice a new method here, namely the <dfn>post()</dfn> method from the <a href="../libraries/input.html">input library</a>. This method makes sure the data is sanitized, protecting you from nasty attacks from others. The input library is loaded by default. At last, you insert our <var>$data</var> array into our database.</p>
+
+<h2>Routing</h2>
+
+<p>Before you can start adding news items into your CodeIgniter application you have to add an extra rule to <dfn>config/routes.php</dfn> file. Make sure your file contains the following. This makes sure CodeIgniter sees 'create' as a method instead of a news item's slug.</p>
+	
+<pre>
+$route['news/create'] = 'news/create';
+$route['news/(:any)'] = 'news/view/$1';
+$route['news'] = 'news';
+$route['(:any)'] = 'pages/view/$1';
+$route['default_controller'] = 'pages/view';
+</pre>
+
+<p>Now point your browser to your local development environment where you installed CodeIgniter and add <dfn>index.php/news/create</dfn> to the URL. Congratulations, you just created your first CodeIgniter application! Add some news and check out the different pages you made.</p>

+<h1>Tutorial - Hard coded pages</h1>
+
+<p>The first thing we're going to do is setting up a controller to handle our hard coded pages. A controller is a class with a collection of methods that represent the different actions you can perform on a certain object. In our case, we want to be able to view a page.</p>
+
+<p class="important"><strong>Note:</strong> This tutorial assumes you've downloaded CodeIgniter and installed the framework in your development environment.</p>
+
+<p>Create a file at <dfn>application/controllers/pages.php</dfn> with the following code.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="9">
+&lt;?php
+class Pages extends CI_Controller {
+
+	public function view($page = 'home')
+	{
+
+	}
+}
+</textarea>
+
+<p>If you're familiar with PHP classes you see that we create a Pages class with a view method that accepts one parameter, <var>$page</var>. Another interesting observation is that the Pages class is extending the CI_Controller class. This means that the new Pages class can access the methods and variables defined in the CI_Controller class. When you look at this class in <dfn>system/core/controller.php</dfn> you can see this class is doing something really important; assigning an instance from the CodeIgniter super object to the <var>$this</var> object. In most of your code, <var>$this</var> is the object you will use to interact with the framework.</p>
+
+<p>Now we've created our first method, it is time to do some basic templating. For this tutorial, we will be creating two views to acts as our footer and header. Let's create our header at <dfn>application/views/templates/header.php</dfn> and ad the following code.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="8">
+<html>
+<head>
+	<title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
+</head>
+<body>
+	<h1>CodeIgniter 2 Tutorial</h1>
+	
+</textarea>
+
+<p>Our header doesn't do anything exciting. It contains the basic HTML code that we will want to display before loading the main view. You can also see that we echo the <var>$title</var> variable, which we didn't define. We will set this variable in the Pages controller a bit later. Let's go ahead and create a footer at <dfn>application/views/templates/footer.php</dfn> that includes the following code.</p>
+	
+<textarea class="textarea" style="width:100%" cols="50" rows="4">
+<strong>&copy; 2011</strong>	
+</body>
+</html>
+</textarea>
+
+<h2>Adding logic to the controller</h2>
+
+<p>Now we've set up the basics so we can finally do some real programming. Earlier we set up our controller with a view method. Because we don't want to write a separate method for every page, we made the view method accept one parameter, the name of the page. These hard coded pages will be located in <dfn>application/views/pages/</dfn>. Create two files in this directory named <dfn>home.php</dfn> and <dfn>about.php</dfn> and put in some HTML content.</p>
+
+<p>In order to load these pages we'll have to check whether these page actually exists. When the page does exist, we load the view for that pages, including the header and footer and display it to the user. If it doesn't, we show a "404 Page not found" error.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="16">
+public function view($page = 'home')
+{
+			
+	if ( ! file_exists('application/views/pages/' . $page . EXT))
+	{
+		show_404();
+	}
+	
+	$data['title'] = ucfirst($page);
+	
+	$this->load->view('templates/header', $data);
+	$this->load->view('pages/'.$page);
+	$this->load->view('templates/footer');
+}	
+</textarea>
+
+<p>The first thing we do is checking whether the page we're looking for does actually exist. We use PHP's native file_exists() to do this check and pass the path where the file is supposed to be. Next is the function show_404(), a CodeIgniter function that renders the default error page and sets the appropriate HTTP headers.</p>
+
+<p>In the header template you saw we were using the <var>$title</var> variable to customize our page title. This is where we define the title, but instead of assigning the value to a variable, we assign it to the title element in the <var>$data</var> array. The last thing we need to do is loading the views in the order we want them to be displayed. We also pass the <var>$data</var> array to the header view to make its elements available in the header view file.<p> 
+	
+<h2>Routing</h2>
+
+<p>Actually, our controller is already functioning. Point your browser to <dfn>index.php/pages/view</dfn> to see your homepage. When you visit <dfn>index.php/pages/view/about</dfn> you will see the about page, again including your header and footer. Now we're going to get rid of the pages/view part in our URI. As you may have seen, CodeIgniter does its routing by the class, method and parameter, separated by slashes.</p>
+
+<p>Open the routing file located at <dfn>application/config/routes.php</dfn> and add the following two lines. Remove all other code that sets any element in the <var>$route</var> array.</p>
+	
+<textarea class="textarea" style="width:100%" cols="50" rows="3">
+$route['(:any)'] = 'pages/view/$1';
+$route['default_controller'] = 'pages/view';
+</textarea>
+
+<p>CodeIgniter reads its routing rules from top to bottom and routes the request to the first matching rule. These routes are stored in the <var>$route</var> array where the keys represent the incoming request and the value the path to the method, as described above.</p> 
+
+<p>The first rule in our <var>$routes</var> array matches every request - using the wildcard operator <dfn>(:any)</dfn> - and passes the value to the view method of the pages class we created earlier. The default controller route makes sure every request to the root goes to the view method as well, which has the first parameter set to 'home' by default.</p>

+
+<h1>Tutorial &minus; News section</h1>
+
+<p>In the last section, we went over some basic concepts of the framework by writing a class that includes static pages. We cleaned up the URI by adding custom routing rules. Now it's time to introduce dynamic content and start using a database.</p>
+
+<h2>Setting up your model</h2>
+
+<p>Instead of writing database operations right in the controller, queries should be placed in a model, so they can easily be reused later. Models are the place where you retrieve, insert, and update information in your database or other data stores. They represent your data.</p>
+
+<p>Open up the <dfn>application/models</dfn> directory and create a new file called <dfn>news_model.php</dfn> and add the following code. Make sure you've configured your database properly as described <a href="../database/configuration.html">here</a>.</p>
+
+<pre>
+&lt;?php
+class News_model extends CI_Model {
+
+	public function __construct()
+	{
+		$this->load->database();
+	}
+}
+</pre>
+
+<p>This code looks similar to the controller code that was used earlier. It creates a new model by extending CI_Model and loads the database library. This will make the database class available through the <var>$this->db</var> object.</p>
+
+<p>Before querying the database, a database schema has to be created. Connect to your database and run the SQL command below. Also add some seed records.</p>
+
+<pre>
+CREATE TABLE news (
+	id int(11) NOT NULL AUTO_INCREMENT,
+	title varchar(128) NOT NULL,
+	slug varchar(128) NOT NULL,
+	text text NOT NULL,
+	PRIMARY KEY (id),
+	KEY slug (slug)
+);
+</pre>
+
+<p>Now that the database and a model have been set up, you'll need a method to get all of our posts from our database. To do this, the database abstraction layer that is included with CodeIgniter — <a href="../database/active_record.html">Active Record</a> — is used. This makes it possible to write your 'queries' once and make them work on <a href="../general/requirements.html">all supported database systems</a>. Add the following code to your model.</p>
+
+<pre>
+public function get_news($slug = FALSE)
+{
+	if ($slug === FALSE)
+	{
+		$query = $this->db->get('news');
+		return $query->result_array();
+	}
+	
+	$query = $this->db->get_where('news', array('slug' => $slug));
+	return $query->row_array();
+}
+</pre>
+
+<p>With this code you can perform two different queries. You can get all news records, or get a news item by its <a href="#" title="a URL friendly version of a string">slug</a>. You might have noticed that the <var>$slug</var> variable wasn't sanitized before running the query; Active Record does this for you.</p>
+
+<h2>Display the news</h2>
+
+<p>Now that the queries are written, the model should be tied to the views that are going to display the news items to the user. This could be done in our pages controller created earlier, but for the sake of clarity, a new "news" controller is defined. Create the new controller at <dfn>application/controllers/news.php</dfn>.</p>
+
+<pre>
+&lt;?php
+class News extends CI_Controller {
+
+	public function __construct()
+	{
+		parent::__construct();
+		$this->load->model('news_model');
+	}
+
+	public function index()
+	{
+		$data['news'] = $this->news_model->get_news();
+	}
+
+	public function view($slug)
+	{
+		$data['news'] = $this->news_model->get_news($slug);
+	}
+}
+</pre>
+
+<p>Looking at the code, you may see some similarity with the files we created earlier. First, the "__construct" method: it calls the constructor of its parent class (<dfn>CI_Controller</dfn>) and loads the model, so it can be used in all other methods in this controller.</p>
+
+<p>Next, there are two methods to view all news items and one for a specific news item. You can see that the <var>$slug</var> variable is passed to the model's method in the second method. The model is using this slug to identify the news item to be returned.</p>
+
+<p>Now the data is retrieved by the controller through our model, but nothing is displayed yet. The next thing to do is passing this data to the views.</p>
+
+<pre>
+public function index()
+{
+	$data['news'] = $this->news_model->get_news();
+	$data['title'] = 'News archive';
+
+	$this->load->view('templates/header', $data);
+	$this->load->view('news/index', $data);
+	$this->load->view('templates/footer');
+}
+</pre>
+
+<p>The code above gets all news records from the model and assigns it to a variable. The value for the title is also assigned to the <var>$data['title']</var> element and all data is passed to the views. You now need to create a view to render the news items. Create <dfn>application/views/news/index.php</dfn> and add the next piece of code.</p>
+
+<pre>
+&lt;?php foreach ($news as $news_item): ?&gt;
+
+    &lt;h2&gt;&lt;?php echo $news_item['title'] ?&gt;&lt;/h2&gt;
+    &lt;div id="main"&gt;
+        &lt;?php echo $news_item['text'] ?&gt;
+    &lt;/div&gt;
+    &lt;p&gt;&lt;a href="news/&lt;?php echo $news_item['slug'] ?&gt;"&gt;View article&lt;/a&gt;&lt;/p&gt;
+
+&lt;?php endforeach ?&gt;
+</pre>
+
+<p>Here, each news item is looped and displayed to the user. You can see we wrote our template in PHP mixed with HTML. If you prefer to use a template language, you can use CodeIgniter's <a href="../libraries/parser.html">Template Parser</a> class or a third party parser.</p>
+
+<p>The news overview page is now done, but a page to display individual news items is still absent. The model created earlier is made in such way that it can easily be used for this functionality. You only need to add some code to the controller and create a new view. Go back to the news controller and add the following lines to the file.</p>
+
+<pre>
+public function view($slug)
+{
+	$data['news_item'] = $this->news_model->get_news($slug);
+
+	if (empty($data['news_item']))
+	{
+		show_404();
+	}
+
+	$data['title'] = $data['news_item']['title'];
+
+	$this->load->view('templates/header', $data);
+	$this->load->view('news/view', $data);
+	$this->load->view('templates/footer');
+}
+</pre>
+
+<p>Instead of calling the <var>get_news()</var> method without a parameter, the <var>$slug</var> variable is passed, so it will return the specific news item. The only things left to do is create the corresponding view at <dfn>application/views/news/view.php</dfn>. Put the following code in this file.</p>
+
+<pre>
+&lt;?php
+echo '&lt;h2&gt;'.$news_item['title'].'&lt;/h2&gt;';
+echo $news_item['text'];
+</pre>
+
+<h2>Routing</h2>
+<p>Because of the wildcard routing rule created earlier, you need need an extra route to view the controller that you just made. Modify your routing file (<dfn>application/config/routes.php</dfn>) so it looks as follows. This makes sure the requests reaches the news controller instead of going directly to the pages controller. The first line routes URI's with a slug to the view method in the news controller.</p>
+
+<pre>
+$route['news/(:any)'] = 'news/view/$1';
+$route['news'] = 'news';
+$route['(:any)'] = 'pages/view/$1';
+$route['default_controller'] = 'pages/view';
+</pre>
+
+<p>Point your browser to your document root, followed by <dfn>index.php/news</dfn> and watch your news page.</p>

+<h1>Tutorial &minus; Static pages</h1>
+
+<p class="important"><strong>Note:</strong> This tutorial assumes you've downloaded CodeIgniter and <a href="../installation/index.html">installed the framework</a> in your development environment.</p>
+
+<p>The first thing you're going to do is set up a <strong>controller</strong> to handle static pages.
+A controller is simply a class that helps delegate work. It is the glue of your
+web application.</p>
+
+<p>For example, when a call is made to: <code>http://example.com/news/latest/10</code> We might imagine
+that there is a controller named &quot;news&quot;. The method being called on news
+would be &quot;latest&quot;. The news method's job could be to grab 10
+news items, and render them on the page. Very often in MVC, you'll see URL
+patterns that match: <code>http://example.com/[controller-class]/[controller-method]/[arguments]</code>
+As URL schemes become more complex, this may change. But for now, this is all we will need to know.</p>
+
+<p>Create a file at <dfn>application/controllers/pages.php</dfn> with the following code.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="10">
+&lt;?php
+
+class Pages extends CI_Controller {
+
+	public function view($page = 'home')
+	{
+
+	}
+}
+</textarea>
+
+<p>You have created a class named &quot;pages&quot;, with a view method that accepts one argument named <var>$page</var>.
+The pages class is extending the CI_Controller class.
+This means that the new pages class can access the methods and variables defined in the CI_Controller class
+(<dfn>system/core/Controller.php</dfn>).</p>
+
+<p>The <strong>controller is what will become the center of every request</strong> to your web application.
+In very technical CodeIgniter discussions, it may be referred to as the <em>super object</em>.
+Like any php class, you refer to it within your controllers as <var>$this</var>.
+Referring to <var>$this</var> is how you will load libraries, views, and generally
+command the framework.</p>
+
+<p>Now you've created your first method, it's time to make some basic page templates.
+We will be creating two &quot;views&quot; (page templates) that act as our page footer and header.</p>
+
+<p>Create the header at <dfn>application/views/templates/header.php</dfn> and add the following code.</p>
+
+<textarea class="textarea" style="width:100%" cols="50" rows="8">
+<html>
+<head>
+	<title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
+</head>
+<body>
+	<h1>CodeIgniter 2 Tutorial</h1>
+	
+</textarea>
+
+<p>The header contains the basic HTML code that you'll want to display before loading the main view, together with a heading. 
+It will also output the <var>$title</var> variable, which we'll define later in the controller.
+Now create a footer at <dfn>application/views/templates/footer.php</dfn> that includes the following code:</p>
+	
+<textarea class="textarea" style="width:100%" cols="50" rows="4">
+<strong>&#38;copy; 2011</strong>	
+</body>
+</html>
+</textarea>
+
+<h2>Adding logic to the controller</h2>
+
+<p>Earlier you set up a controller with a view() method. The method accepts one parameter, which is the name of the page to be loaded.
+The static page templates will be located in the <dfn>application/views/pages/</dfn> directory.</p>
+
+<p>In that directory, create two files named <dfn>home.php</dfn> and <dfn>about.php</dfn>. 
+Within those files, type some text &minus; anything you'd like &minus; and save them. 
+If you like to be particularly un-original, try &quot;Hello World!&quot;.</p>
+
+<p>In order to load those pages, you'll have to check whether the requested page actually exists:</p>
+
+<pre>
+public function view($page = 'home')
+{
+			
+	if ( ! file_exists('application/views/pages/'.$page.'.php'))
+	{
+		// Whoops, we don't have a page for that!
+		show_404();
+	}
+	
+	$data['title'] = ucfirst($page); // Capitalize the first letter
+	
+	$this->load->view('templates/header', $data);
+	$this->load->view('pages/'.$page, $data);
+	$this->load->view('templates/footer', $data);
+
+}
+</pre>
+
+<p>Now, when the page does exist, it is loaded, including the header and footer, and displayed to the user. If the page doesn't exist, a "404 Page not found" error is shown.</p>
+
+<p>The first line in this method checks whether the page actually exists. PHP's native <var>file_exists()</var> function is used to check whether the file is where it's expected to be. <var>show_404()</var> is a built-in CodeIgniter function that renders the default error page.</p>
+
+<p>In the header template, the <var>$title</var> variable was used to customize the page title. The value of title is defined in this method, but instead of assigning the value to a variable, it is assigned to the title element in the <var>$data</var> array.</p>
+
+<p>The last thing that has to be done is loading the views in the order they should be displayed.
+The second parameter in the <var>view()</var> method is used to pass values to the view. Each value in the <var>$data</var> array is assigned to a variable with the name of its key. So the value of <var>$data['title']</var> in the controller is equivalent to $title in the view.<p>
+	
+<h2>Routing</h2>
+
+<p>The controller is now functioning! Point your browser to <dfn>[your-site-url]index.php/pages/view</dfn> to see your page. When you visit <dfn>index.php/pages/view/about</dfn> you'll see the about page, again including the header and footer.</p>
+
+<p>Using custom routing rules, you have the power to map any URI to any controller and method, and break free from the normal convention:
+<code>http://example.com/[controller-class]/[controller-method]/[arguments]</code></p>
+
+<p>Let's do that. Open the routing file located at <dfn>application/config/routes.php</dfn> and add the following two lines. Remove all other code that sets any element in the <var>$route</var> array.</p>
+	
+<pre>
+$route['default_controller'] = 'pages/view';
+$route['(:any)'] = 'pages/view/$1';
+</pre>
+
+<p>CodeIgniter reads its routing rules from top to bottom and routes the request to the first matching rule. Each rule is a regular expression
+(left-side) mapped to a controller and method name separated by slashes (right-side).
+When a request comes in, CodeIgniter looks for the first match, and calls the appropriate controller and method, possibly with arguments.</p>
+
+<p>More information about routing can be found in the URI Routing <a href="../general/routing.html">documentation</a>.</p>
+
+<p>Here, the second rule in the <var>$routes</var> array matches <strong>any</strong> request using the wildcard string <dfn>(:any)</dfn>.
+and passes the parameter to the view() method of the pages class.</p>
+
+<p>Now visit <dfn>index.php/about</dfn>. Did it get routed correctly to the <var>view()</var> method
+in the pages controller? Awesome!</p>

-<p>You now know how you can read data from a database using CodeIgnite, but you haven't written any information to the database yet. In this section you'll expand your news controller and model created earlier to include this functionality.</p>
-
-<h2>Create a form</h2>
-
-<p>To input data into the database you need to create a form where you can input the information to be stored. This means you'll be needing a form with two fields, one for the title and one for the text. You'll derive the slug from our title in the model. Create the new view at <dfn>application/views/news/create.php</dfn>.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="16">
-<h2>Create a news item</h2>
-
-&lt;?php echo validation_errors(); ?>
-
-&lt;?php echo form_open('news/create') ?>
-
-	<label for="title">Title</label> 
-	<input type="input" name="title" /><br />
-
-	<label for="text">Text</label>
-	<textarea name="text">&lt;/textarea><br />
-	
-	<input type="submit" name="submit" value="Create news item" /> 
-
-&lt;/form>
-</textarea>
-
-<p>There are only two things here that probably look unfamiliar to you: the <dfn>form_open()</dfn> function and the <dfn>validation_errors()</dfn> function.</p>
-
-<p>The first function is provided by the <a href="../helpers/form_helper.html">form helper</a> and renders the form element and adds extra functionality, like adding a hidden <a href="../libraries/security.html">CSFR prevention field</a>. The latter is used to report errors related to form validation.</p>
-
-<p>Go back to your news controller. You're going to do two things here, check whether the form was submitted and whether the submitted data passed the validation rules. You'll use the <a href="../libraries/form_validation.html">form validation</a> library to do this.</p>
-
-<pre>
-public function create()
-{
-	$this->load->helper('form');
-	$this->load->library('form_validation');
-	
-	$data['title'] = 'Create a news item';
-	
-	$this->form_validation->set_rules('title', 'Title', 'required');
-	$this->form_validation->set_rules('text', 'text', 'required');
-	
-	if ($this->form_validation->run() === FALSE)
-	{
-		$this->load->view('templates/header', $data);	
-		$this->load->view('news/create');
-		$this->load->view('templates/footer');
-		
-	}
-	else
-	{
-		$this->news_model->set_news();
-		$this->load->view('news/success');
-	}
-}
-</pre>
-
-<p>The code above adds a lot of functionality. The first few lines load the form helper and the form validation library. After that, rules for the form validation are set. The <var>set_rules()</var> method takes three arguments; the name of the input field, the name to be used in error messages, and the rule. In this case the title and text fields are required.</p>
-
-<p>CodeIgniter has a powerful form validation library as demonstrated above. You can read <a href="../libraries/form_validation.html">more about this library here</a>.</p>
-
-<p>Continuing down, you can see a condition that checks whether the form validation ran successfully. If it did not, the form is displayed, if it was submitted <strong>and</strong> passed all the rules, the model is called. After this, a view is loaded to display a success message. Create a view at <dfn>application/view/news/success.php</dfn> and write a success message.</p>
-
-<h2>Model</h2>
-
-<p>The only thing that remains is writing a method that writes the data to the database. You'll use the Active Record class to insert the information and use the input library to get the posted data. Open up the model created earlier and add the following:</p>
-
-<pre>
-public function set_news()
-{
-	$this->load->helper('url');
-	
-	$slug = url_title($this->input->post('title'), 'dash', TRUE);
-	
-	$data = array(
-		'title' => $this->input->post('title'),
-		'slug' => $slug,
-		'text' => $this->input->post('text')
-	);
-	
-	return $this->db->insert('news', $data);
-}
-</pre>
-
-<p>This new method takes care of inserting the news item into the database. The third line contains a new function, <dfn>url_title()</dfn>. This function - provided by the <a href="../helpers/url_helper.html">URL helper</a> - strips down the string you pass it, replacing all spaces by dashes (-) and makes sure everything is in lowercase characters. This leaves you with a nice slug, perfect for creating URIs.</p>
-	
-<p>Let's continue with preparing the record that is going to be inserted later, inside the <var>$data</var> array. Each element corresponds with a column in the database table created earlier. You might notice a new method here, namely the <dfn>post()</dfn> method from the <a href="../libraries/input.html">input library</a>. This method makes sure the data is sanitized, protecting you from nasty attacks from others. The input library is loaded by default. At last, you insert our <var>$data</var> array into our database.</p>
-
-<h2>Routing</h2>
-
-<p>Before you can start adding news items into your CodeIgniter application you have to add an extra rule to <dfn>config/routes.php</dfn> file. Make sure your file contains the following. This makes sure CodeIgniter sees 'create' as a method instead of a news item's slug.</p>
-	
-<pre>
-$route['news/create'] = 'news/create';
-$route['news/(:any)'] = 'news/view/$1';
-$route['news'] = 'news';
-$route['(:any)'] = 'pages/view/$1';
-$route['default_controller'] = 'pages/view';
-</pre>
-
-<p>Now point your browser to your local development environment where you installed CodeIgniter and add <dfn>index.php/news/create</dfn> to the URL. Congratulations, you just created your first CodeIgniter application! Add some news and check out the different pages you made.</p>

+Tutorial - Create news items
+============================
+
+You now know how you can read data from a database using CodeIgnite, but
+you haven't written any information to the database yet. In this section
+you'll expand your news controller and model created earlier to include
+this functionality.
+
+Create a form
+-------------
+
+To input data into the database you need to create a form where you can
+input the information to be stored. This means you'll be needing a form
+with two fields, one for the title and one for the text. You'll derive
+the slug from our title in the model. Create the new view at
+application/views/news/create.php.
+
+Create a news item
+------------------
+
+<?php echo validation\_errors(); ?> <?php echo form\_open('news/create')
+?> Title
+ Text </textarea>
+ </form>
+
+There are only two things here that probably look unfamiliar to you: the
+form\_open() function and the validation\_errors() function.
+
+The first function is provided by the `form
+helper <../helpers/form_helper.html>`_ and renders the form element and
+adds extra functionality, like adding a hidden `CSFR prevention
+field <../libraries/security.html>`_. The latter is used to report
+errors related to form validation.
+
+Go back to your news controller. You're going to do two things here,
+check whether the form was submitted and whether the submitted data
+passed the validation rules. You'll use the `form
+validation <../libraries/form_validation.html>`_ library to do this.
+
+::
+
+    public function create()
+    {
+        $this->load->helper('form');
+        $this->load->library('form_validation');
+        
+        $data['title'] = 'Create a news item';
+        
+        $this->form_validation->set_rules('title', 'Title', 'required');
+        $this->form_validation->set_rules('text', 'text', 'required');
+        
+        if ($this->form_validation->run() === FALSE)
+        {
+            $this->load->view('templates/header', $data);   
+            $this->load->view('news/create');
+            $this->load->view('templates/footer');
+            
+        }
+        else
+        {
+            $this->news_model->set_news();
+            $this->load->view('news/success');
+        }
+    }
+
+The code above adds a lot of functionality. The first few lines load the
+form helper and the form validation library. After that, rules for the
+form validation are set. The set\_rules() method takes three arguments;
+the name of the input field, the name to be used in error messages, and
+the rule. In this case the title and text fields are required.
+
+CodeIgniter has a powerful form validation library as demonstrated
+above. You can read `more about this library
+here <../libraries/form_validation.html>`_.
+
+Continuing down, you can see a condition that checks whether the form
+validation ran successfully. If it did not, the form is displayed, if it
+was submitted **and** passed all the rules, the model is called. After
+this, a view is loaded to display a success message. Create a view at
+application/view/news/success.php and write a success message.
+
+Model
+-----
+
+The only thing that remains is writing a method that writes the data to
+the database. You'll use the Active Record class to insert the
+information and use the input library to get the posted data. Open up
+the model created earlier and add the following:
+
+::
+
+    public function set_news()
+    {
+        $this->load->helper('url');
+        
+        $slug = url_title($this->input->post('title'), 'dash', TRUE);
+        
+        $data = array(
+            'title' => $this->input->post('title'),
+            'slug' => $slug,
+            'text' => $this->input->post('text')
+        );
+        
+        return $this->db->insert('news', $data);
+    }
+
+This new method takes care of inserting the news item into the database.
+The third line contains a new function, url\_title(). This function -
+provided by the `URL helper <../helpers/url_helper.html>`_ - strips down
+the string you pass it, replacing all spaces by dashes (-) and makes
+sure everything is in lowercase characters. This leaves you with a nice
+slug, perfect for creating URIs.
+
+Let's continue with preparing the record that is going to be inserted
+later, inside the $data array. Each element corresponds with a column in
+the database table created earlier. You might notice a new method here,
+namely the post() method from the `input
+library <../libraries/input.html>`_. This method makes sure the data is
+sanitized, protecting you from nasty attacks from others. The input
+library is loaded by default. At last, you insert our $data array into
+our database.
+
+Routing
+-------
+
+Before you can start adding news items into your CodeIgniter application
+you have to add an extra rule to config/routes.php file. Make sure your
+file contains the following. This makes sure CodeIgniter sees 'create'
+as a method instead of a news item's slug.
+
+::
+
+    $route['news/create'] = 'news/create';
+    $route['news/(:any)'] = 'news/view/$1';
+    $route['news'] = 'news';
+    $route['(:any)'] = 'pages/view/$1';
+    $route['default_controller'] = 'pages/view';
+
+Now point your browser to your local development environment where you
+installed CodeIgniter and add index.php/news/create to the URL.
+Congratulations, you just created your first CodeIgniter application!
+Add some news and check out the different pages you made.

-<h1>Tutorial - Hard coded pages</h1>
-
-<p>The first thing we're going to do is setting up a controller to handle our hard coded pages. A controller is a class with a collection of methods that represent the different actions you can perform on a certain object. In our case, we want to be able to view a page.</p>
-
-<p class="important"><strong>Note:</strong> This tutorial assumes you've downloaded CodeIgniter and installed the framework in your development environment.</p>
-
-<p>Create a file at <dfn>application/controllers/pages.php</dfn> with the following code.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="9">
-&lt;?php
-class Pages extends CI_Controller {
-
-	public function view($page = 'home')
-	{
-
-	}
-}
-</textarea>
-
-<p>If you're familiar with PHP classes you see that we create a Pages class with a view method that accepts one parameter, <var>$page</var>. Another interesting observation is that the Pages class is extending the CI_Controller class. This means that the new Pages class can access the methods and variables defined in the CI_Controller class. When you look at this class in <dfn>system/core/controller.php</dfn> you can see this class is doing something really important; assigning an instance from the CodeIgniter super object to the <var>$this</var> object. In most of your code, <var>$this</var> is the object you will use to interact with the framework.</p>
-
-<p>Now we've created our first method, it is time to do some basic templating. For this tutorial, we will be creating two views to acts as our footer and header. Let's create our header at <dfn>application/views/templates/header.php</dfn> and ad the following code.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="8">
-<html>
-<head>
-	<title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
-</head>
-<body>
-	<h1>CodeIgniter 2 Tutorial</h1>
-	
-</textarea>
-
-<p>Our header doesn't do anything exciting. It contains the basic HTML code that we will want to display before loading the main view. You can also see that we echo the <var>$title</var> variable, which we didn't define. We will set this variable in the Pages controller a bit later. Let's go ahead and create a footer at <dfn>application/views/templates/footer.php</dfn> that includes the following code.</p>
-	
-<textarea class="textarea" style="width:100%" cols="50" rows="4">
-<strong>&copy; 2011</strong>	
-</body>
-</html>
-</textarea>
-
-<h2>Adding logic to the controller</h2>
-
-<p>Now we've set up the basics so we can finally do some real programming. Earlier we set up our controller with a view method. Because we don't want to write a separate method for every page, we made the view method accept one parameter, the name of the page. These hard coded pages will be located in <dfn>application/views/pages/</dfn>. Create two files in this directory named <dfn>home.php</dfn> and <dfn>about.php</dfn> and put in some HTML content.</p>
-
-<p>In order to load these pages we'll have to check whether these page actually exists. When the page does exist, we load the view for that pages, including the header and footer and display it to the user. If it doesn't, we show a "404 Page not found" error.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="16">
-public function view($page = 'home')
-{
-			
-	if ( ! file_exists('application/views/pages/' . $page . EXT))
-	{
-		show_404();
-	}
-	
-	$data['title'] = ucfirst($page);
-	
-	$this->load->view('templates/header', $data);
-	$this->load->view('pages/'.$page);
-	$this->load->view('templates/footer');
-}	
-</textarea>
-
-<p>The first thing we do is checking whether the page we're looking for does actually exist. We use PHP's native file_exists() to do this check and pass the path where the file is supposed to be. Next is the function show_404(), a CodeIgniter function that renders the default error page and sets the appropriate HTTP headers.</p>
-
-<p>In the header template you saw we were using the <var>$title</var> variable to customize our page title. This is where we define the title, but instead of assigning the value to a variable, we assign it to the title element in the <var>$data</var> array. The last thing we need to do is loading the views in the order we want them to be displayed. We also pass the <var>$data</var> array to the header view to make its elements available in the header view file.<p> 
-	
-<h2>Routing</h2>
-
-<p>Actually, our controller is already functioning. Point your browser to <dfn>index.php/pages/view</dfn> to see your homepage. When you visit <dfn>index.php/pages/view/about</dfn> you will see the about page, again including your header and footer. Now we're going to get rid of the pages/view part in our URI. As you may have seen, CodeIgniter does its routing by the class, method and parameter, separated by slashes.</p>
-
-<p>Open the routing file located at <dfn>application/config/routes.php</dfn> and add the following two lines. Remove all other code that sets any element in the <var>$route</var> array.</p>
-	
-<textarea class="textarea" style="width:100%" cols="50" rows="3">
-$route['(:any)'] = 'pages/view/$1';
-$route['default_controller'] = 'pages/view';
-</textarea>
-
-<p>CodeIgniter reads its routing rules from top to bottom and routes the request to the first matching rule. These routes are stored in the <var>$route</var> array where the keys represent the incoming request and the value the path to the method, as described above.</p> 
-
-<p>The first rule in our <var>$routes</var> array matches every request - using the wildcard operator <dfn>(:any)</dfn> - and passes the value to the view method of the pages class we created earlier. The default controller route makes sure every request to the root goes to the view method as well, which has the first parameter set to 'home' by default.</p>

+CodeIgniter 2 Tutorial
+======================
+
+Our header doesn't do anything exciting. It contains the basic HTML code
+that we will want to display before loading the main view. You can also
+see that we echo the $title variable, which we didn't define. We will
+set this variable in the Pages controller a bit later. Let's go ahead
+and create a footer at application/views/templates/footer.php that
+includes the following code.
+
+**© 2011**
+
+Adding logic to the controller
+------------------------------
+
+Now we've set up the basics so we can finally do some real programming.
+Earlier we set up our controller with a view method. Because we don't
+want to write a separate method for every page, we made the view method
+accept one parameter, the name of the page. These hard coded pages will
+be located in application/views/pages/. Create two files in this
+directory named home.php and about.php and put in some HTML content.
+
+In order to load these pages we'll have to check whether these page
+actually exists. When the page does exist, we load the view for that
+pages, including the header and footer and display it to the user. If it
+doesn't, we show a "404 Page not found" error.
+
+public function view($page = 'home') { if ( !
+file\_exists('application/views/pages/' . $page . EXT)) { show\_404(); }
+$data['title'] = ucfirst($page); $this->load->view('templates/header',
+$data); $this->load->view('pages/'.$page);
+$this->load->view('templates/footer'); }
+
+The first thing we do is checking whether the page we're looking for
+does actually exist. We use PHP's native file\_exists() to do this check
+and pass the path where the file is supposed to be. Next is the function
+show\_404(), a CodeIgniter function that renders the default error page
+and sets the appropriate HTTP headers.
+
+In the header template you saw we were using the $title variable to
+customize our page title. This is where we define the title, but instead
+of assigning the value to a variable, we assign it to the title element
+in the $data array. The last thing we need to do is loading the views in
+the order we want them to be displayed. We also pass the $data array to
+the header view to make its elements available in the header view file.
+
+Routing
+-------
+
+Actually, our controller is already functioning. Point your browser to
+index.php/pages/view to see your homepage. When you visit
+index.php/pages/view/about you will see the about page, again including
+your header and footer. Now we're going to get rid of the pages/view
+part in our URI. As you may have seen, CodeIgniter does its routing by
+the class, method and parameter, separated by slashes.
+
+Open the routing file located at application/config/routes.php and add
+the following two lines. Remove all other code that sets any element in
+the $route array.
+
+$route['(:any)'] = 'pages/view/$1'; $route['default\_controller'] =
+'pages/view';
+
+CodeIgniter reads its routing rules from top to bottom and routes the
+request to the first matching rule. These routes are stored in the
+$route array where the keys represent the incoming request and the value
+the path to the method, as described above.
+
+The first rule in our $routes array matches every request - using the
+wildcard operator (:any) - and passes the value to the view method of
+the pages class we created earlier. The default controller route makes
+sure every request to the root goes to the view method as well, which
+has the first parameter set to 'home' by default.

-<h1>Tutorial &minus; News section</h1>
-
-<p>In the last section, we went over some basic concepts of the framework by writing a class that includes static pages. We cleaned up the URI by adding custom routing rules. Now it's time to introduce dynamic content and start using a database.</p>
-
-<h2>Setting up your model</h2>
-
-<p>Instead of writing database operations right in the controller, queries should be placed in a model, so they can easily be reused later. Models are the place where you retrieve, insert, and update information in your database or other data stores. They represent your data.</p>
-
-<p>Open up the <dfn>application/models</dfn> directory and create a new file called <dfn>news_model.php</dfn> and add the following code. Make sure you've configured your database properly as described <a href="../database/configuration.html">here</a>.</p>
-
-<pre>
-&lt;?php
-class News_model extends CI_Model {
-
-	public function __construct()
-	{
-		$this->load->database();
-	}
-}
-</pre>
-
-<p>This code looks similar to the controller code that was used earlier. It creates a new model by extending CI_Model and loads the database library. This will make the database class available through the <var>$this->db</var> object.</p>
-
-<p>Before querying the database, a database schema has to be created. Connect to your database and run the SQL command below. Also add some seed records.</p>
-
-<pre>
-CREATE TABLE news (
-	id int(11) NOT NULL AUTO_INCREMENT,
-	title varchar(128) NOT NULL,
-	slug varchar(128) NOT NULL,
-	text text NOT NULL,
-	PRIMARY KEY (id),
-	KEY slug (slug)
-);
-</pre>
-
-<p>Now that the database and a model have been set up, you'll need a method to get all of our posts from our database. To do this, the database abstraction layer that is included with CodeIgniter — <a href="../database/active_record.html">Active Record</a> — is used. This makes it possible to write your 'queries' once and make them work on <a href="../general/requirements.html">all supported database systems</a>. Add the following code to your model.</p>
-
-<pre>
-public function get_news($slug = FALSE)
-{
-	if ($slug === FALSE)
-	{
-		$query = $this->db->get('news');
-		return $query->result_array();
-	}
-	
-	$query = $this->db->get_where('news', array('slug' => $slug));
-	return $query->row_array();
-}
-</pre>
-
-<p>With this code you can perform two different queries. You can get all news records, or get a news item by its <a href="#" title="a URL friendly version of a string">slug</a>. You might have noticed that the <var>$slug</var> variable wasn't sanitized before running the query; Active Record does this for you.</p>
-
-<h2>Display the news</h2>
-
-<p>Now that the queries are written, the model should be tied to the views that are going to display the news items to the user. This could be done in our pages controller created earlier, but for the sake of clarity, a new "news" controller is defined. Create the new controller at <dfn>application/controllers/news.php</dfn>.</p>
-
-<pre>
-&lt;?php
-class News extends CI_Controller {
-
-	public function __construct()
-	{
-		parent::__construct();
-		$this->load->model('news_model');
-	}
-
-	public function index()
-	{
-		$data['news'] = $this->news_model->get_news();
-	}
-
-	public function view($slug)
-	{
-		$data['news'] = $this->news_model->get_news($slug);
-	}
-}
-</pre>
-
-<p>Looking at the code, you may see some similarity with the files we created earlier. First, the "__construct" method: it calls the constructor of its parent class (<dfn>CI_Controller</dfn>) and loads the model, so it can be used in all other methods in this controller.</p>
-
-<p>Next, there are two methods to view all news items and one for a specific news item. You can see that the <var>$slug</var> variable is passed to the model's method in the second method. The model is using this slug to identify the news item to be returned.</p>
-
-<p>Now the data is retrieved by the controller through our model, but nothing is displayed yet. The next thing to do is passing this data to the views.</p>
-
-<pre>
-public function index()
-{
-	$data['news'] = $this->news_model->get_news();
-	$data['title'] = 'News archive';
-
-	$this->load->view('templates/header', $data);
-	$this->load->view('news/index', $data);
-	$this->load->view('templates/footer');
-}
-</pre>
-
-<p>The code above gets all news records from the model and assigns it to a variable. The value for the title is also assigned to the <var>$data['title']</var> element and all data is passed to the views. You now need to create a view to render the news items. Create <dfn>application/views/news/index.php</dfn> and add the next piece of code.</p>
-
-<pre>
-&lt;?php foreach ($news as $news_item): ?&gt;
-
-    &lt;h2&gt;&lt;?php echo $news_item['title'] ?&gt;&lt;/h2&gt;
-    &lt;div id="main"&gt;
-        &lt;?php echo $news_item['text'] ?&gt;
-    &lt;/div&gt;
-    &lt;p&gt;&lt;a href="news/&lt;?php echo $news_item['slug'] ?&gt;"&gt;View article&lt;/a&gt;&lt;/p&gt;
-
-&lt;?php endforeach ?&gt;
-</pre>
-
-<p>Here, each news item is looped and displayed to the user. You can see we wrote our template in PHP mixed with HTML. If you prefer to use a template language, you can use CodeIgniter's <a href="../libraries/parser.html">Template Parser</a> class or a third party parser.</p>
-
-<p>The news overview page is now done, but a page to display individual news items is still absent. The model created earlier is made in such way that it can easily be used for this functionality. You only need to add some code to the controller and create a new view. Go back to the news controller and add the following lines to the file.</p>
-
-<pre>
-public function view($slug)
-{
-	$data['news_item'] = $this->news_model->get_news($slug);
-
-	if (empty($data['news_item']))
-	{
-		show_404();
-	}
-
-	$data['title'] = $data['news_item']['title'];
-
-	$this->load->view('templates/header', $data);
-	$this->load->view('news/view', $data);
-	$this->load->view('templates/footer');
-}
-</pre>
-
-<p>Instead of calling the <var>get_news()</var> method without a parameter, the <var>$slug</var> variable is passed, so it will return the specific news item. The only things left to do is create the corresponding view at <dfn>application/views/news/view.php</dfn>. Put the following code in this file.</p>
-
-<pre>
-&lt;?php
-echo '&lt;h2&gt;'.$news_item['title'].'&lt;/h2&gt;';
-echo $news_item['text'];
-</pre>
-
-<h2>Routing</h2>
-<p>Because of the wildcard routing rule created earlier, you need need an extra route to view the controller that you just made. Modify your routing file (<dfn>application/config/routes.php</dfn>) so it looks as follows. This makes sure the requests reaches the news controller instead of going directly to the pages controller. The first line routes URI's with a slug to the view method in the news controller.</p>
-
-<pre>
-$route['news/(:any)'] = 'news/view/$1';
-$route['news'] = 'news';
-$route['(:any)'] = 'pages/view/$1';
-$route['default_controller'] = 'pages/view';
-</pre>
-
-<p>Point your browser to your document root, followed by <dfn>index.php/news</dfn> and watch your news page.</p>

+Tutorial − News section
+=======================
+
+In the last section, we went over some basic concepts of the framework
+by writing a class that includes static pages. We cleaned up the URI by
+adding custom routing rules. Now it's time to introduce dynamic content
+and start using a database.
+
+Setting up your model
+---------------------
+
+Instead of writing database operations right in the controller, queries
+should be placed in a model, so they can easily be reused later. Models
+are the place where you retrieve, insert, and update information in your
+database or other data stores. They represent your data.
+
+Open up the application/models directory and create a new file called
+news\_model.php and add the following code. Make sure you've configured
+your database properly as described
+`here <../database/configuration.html>`_.
+
+::
+
+    <?php
+    class News_model extends CI_Model {
+
+        public function __construct()
+        {
+            $this->load->database();
+        }
+    }
+
+This code looks similar to the controller code that was used earlier. It
+creates a new model by extending CI\_Model and loads the database
+library. This will make the database class available through the
+$this->db object.
+
+Before querying the database, a database schema has to be created.
+Connect to your database and run the SQL command below. Also add some
+seed records.
+
+::
+
+    CREATE TABLE news (
+        id int(11) NOT NULL AUTO_INCREMENT,
+        title varchar(128) NOT NULL,
+        slug varchar(128) NOT NULL,
+        text text NOT NULL,
+        PRIMARY KEY (id),
+        KEY slug (slug)
+    );
+
+Now that the database and a model have been set up, you'll need a method
+to get all of our posts from our database. To do this, the database
+abstraction layer that is included with CodeIgniter — `Active
+Record <../database/active_record.html>`_ — is used. This makes it
+possible to write your 'queries' once and make them work on `all
+supported database systems <../general/requirements.html>`_. Add the
+following code to your model.
+
+::
+
+    public function get_news($slug = FALSE)
+    {
+        if ($slug === FALSE)
+        {
+            $query = $this->db->get('news');
+            return $query->result_array();
+        }
+        
+        $query = $this->db->get_where('news', array('slug' => $slug));
+        return $query->row_array();
+    }
+
+With this code you can perform two different queries. You can get all
+news records, or get a news item by its `slug <#>`_. You might have
+noticed that the $slug variable wasn't sanitized before running the
+query; Active Record does this for you.
+
+Display the news
+----------------
+
+Now that the queries are written, the model should be tied to the views
+that are going to display the news items to the user. This could be done
+in our pages controller created earlier, but for the sake of clarity, a
+new "news" controller is defined. Create the new controller at
+application/controllers/news.php.
+
+::
+
+    <?php
+    class News extends CI_Controller {
+
+        public function __construct()
+        {
+            parent::__construct();
+            $this->load->model('news_model');
+        }
+
+        public function index()
+        {
+            $data['news'] = $this->news_model->get_news();
+        }
+
+        public function view($slug)
+        {
+            $data['news'] = $this->news_model->get_news($slug);
+        }
+    }
+
+Looking at the code, you may see some similarity with the files we
+created earlier. First, the "\_\_construct" method: it calls the
+constructor of its parent class (CI\_Controller) and loads the model, so
+it can be used in all other methods in this controller.
+
+Next, there are two methods to view all news items and one for a
+specific news item. You can see that the $slug variable is passed to the
+model's method in the second method. The model is using this slug to
+identify the news item to be returned.
+
+Now the data is retrieved by the controller through our model, but
+nothing is displayed yet. The next thing to do is passing this data to
+the views.
+
+::
+
+    public function index()
+    {
+        $data['news'] = $this->news_model->get_news();
+        $data['title'] = 'News archive';
+
+        $this->load->view('templates/header', $data);
+        $this->load->view('news/index', $data);
+        $this->load->view('templates/footer');
+    }
+
+The code above gets all news records from the model and assigns it to a
+variable. The value for the title is also assigned to the $data['title']
+element and all data is passed to the views. You now need to create a
+view to render the news items. Create application/views/news/index.php
+and add the next piece of code.
+
+::
+
+    <?php foreach ($news as $news_item): ?>
+
+        <h2><?php echo $news_item['title'] ?></h2>
+        <div id="main">
+            <?php echo $news_item['text'] ?>
+        </div>
+        <p><a href="news/<?php echo $news_item['slug'] ?>">View article</a></p>
+
+    <?php endforeach ?>
+
+Here, each news item is looped and displayed to the user. You can see we
+wrote our template in PHP mixed with HTML. If you prefer to use a
+template language, you can use CodeIgniter's `Template
+Parser <../libraries/parser.html>`_ class or a third party parser.
+
+The news overview page is now done, but a page to display individual
+news items is still absent. The model created earlier is made in such
+way that it can easily be used for this functionality. You only need to
+add some code to the controller and create a new view. Go back to the
+news controller and add the following lines to the file.
+
+::
+
+    public function view($slug)
+    {
+        $data['news_item'] = $this->news_model->get_news($slug);
+
+        if (empty($data['news_item']))
+        {
+            show_404();
+        }
+
+        $data['title'] = $data['news_item']['title'];
+
+        $this->load->view('templates/header', $data);
+        $this->load->view('news/view', $data);
+        $this->load->view('templates/footer');
+    }
+
+Instead of calling the get\_news() method without a parameter, the $slug
+variable is passed, so it will return the specific news item. The only
+things left to do is create the corresponding view at
+application/views/news/view.php. Put the following code in this file.
+
+::
+
+    <?php
+    echo '<h2>'.$news_item['title'].'</h2>';
+    echo $news_item['text'];
+
+Routing
+-------
+
+Because of the wildcard routing rule created earlier, you need need an
+extra route to view the controller that you just made. Modify your
+routing file (application/config/routes.php) so it looks as follows.
+This makes sure the requests reaches the news controller instead of
+going directly to the pages controller. The first line routes URI's with
+a slug to the view method in the news controller.
+
+::
+
+    $route['news/(:any)'] = 'news/view/$1';
+    $route['news'] = 'news';
+    $route['(:any)'] = 'pages/view/$1';
+    $route['default_controller'] = 'pages/view';
+
+Point your browser to your document root, followed by index.php/news and
+watch your news page.

-<h1>Tutorial &minus; Static pages</h1>
-
-<p class="important"><strong>Note:</strong> This tutorial assumes you've downloaded CodeIgniter and <a href="../installation/index.html">installed the framework</a> in your development environment.</p>
-
-<p>The first thing you're going to do is set up a <strong>controller</strong> to handle static pages.
-A controller is simply a class that helps delegate work. It is the glue of your
-web application.</p>
-
-<p>For example, when a call is made to: <code>http://example.com/news/latest/10</code> We might imagine
-that there is a controller named &quot;news&quot;. The method being called on news
-would be &quot;latest&quot;. The news method's job could be to grab 10
-news items, and render them on the page. Very often in MVC, you'll see URL
-patterns that match: <code>http://example.com/[controller-class]/[controller-method]/[arguments]</code>
-As URL schemes become more complex, this may change. But for now, this is all we will need to know.</p>
-
-<p>Create a file at <dfn>application/controllers/pages.php</dfn> with the following code.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="10">
-&lt;?php
-
-class Pages extends CI_Controller {
-
-	public function view($page = 'home')
-	{
-
-	}
-}
-</textarea>
-
-<p>You have created a class named &quot;pages&quot;, with a view method that accepts one argument named <var>$page</var>.
-The pages class is extending the CI_Controller class.
-This means that the new pages class can access the methods and variables defined in the CI_Controller class
-(<dfn>system/core/Controller.php</dfn>).</p>
-
-<p>The <strong>controller is what will become the center of every request</strong> to your web application.
-In very technical CodeIgniter discussions, it may be referred to as the <em>super object</em>.
-Like any php class, you refer to it within your controllers as <var>$this</var>.
-Referring to <var>$this</var> is how you will load libraries, views, and generally
-command the framework.</p>
-
-<p>Now you've created your first method, it's time to make some basic page templates.
-We will be creating two &quot;views&quot; (page templates) that act as our page footer and header.</p>
-
-<p>Create the header at <dfn>application/views/templates/header.php</dfn> and add the following code.</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="8">
-<html>
-<head>
-	<title><?php echo $title ?> - CodeIgniter 2 Tutorial</title>
-</head>
-<body>
-	<h1>CodeIgniter 2 Tutorial</h1>
-	
-</textarea>
-
-<p>The header contains the basic HTML code that you'll want to display before loading the main view, together with a heading. 
-It will also output the <var>$title</var> variable, which we'll define later in the controller.
-Now create a footer at <dfn>application/views/templates/footer.php</dfn> that includes the following code:</p>
-	
-<textarea class="textarea" style="width:100%" cols="50" rows="4">
-<strong>&#38;copy; 2011</strong>	
-</body>
-</html>
-</textarea>
-
-<h2>Adding logic to the controller</h2>
-
-<p>Earlier you set up a controller with a view() method. The method accepts one parameter, which is the name of the page to be loaded.
-The static page templates will be located in the <dfn>application/views/pages/</dfn> directory.</p>
-
-<p>In that directory, create two files named <dfn>home.php</dfn> and <dfn>about.php</dfn>. 
-Within those files, type some text &minus; anything you'd like &minus; and save them. 
-If you like to be particularly un-original, try &quot;Hello World!&quot;.</p>
-
-<p>In order to load those pages, you'll have to check whether the requested page actually exists:</p>
-
-<pre>
-public function view($page = 'home')
-{
-			
-	if ( ! file_exists('application/views/pages/'.$page.'.php'))
-	{
-		// Whoops, we don't have a page for that!
-		show_404();
-	}
-	
-	$data['title'] = ucfirst($page); // Capitalize the first letter
-	
-	$this->load->view('templates/header', $data);
-	$this->load->view('pages/'.$page, $data);
-	$this->load->view('templates/footer', $data);
-
-}
-</pre>
-
-<p>Now, when the page does exist, it is loaded, including the header and footer, and displayed to the user. If the page doesn't exist, a "404 Page not found" error is shown.</p>
-
-<p>The first line in this method checks whether the page actually exists. PHP's native <var>file_exists()</var> function is used to check whether the file is where it's expected to be. <var>show_404()</var> is a built-in CodeIgniter function that renders the default error page.</p>
-
-<p>In the header template, the <var>$title</var> variable was used to customize the page title. The value of title is defined in this method, but instead of assigning the value to a variable, it is assigned to the title element in the <var>$data</var> array.</p>
-
-<p>The last thing that has to be done is loading the views in the order they should be displayed.
-The second parameter in the <var>view()</var> method is used to pass values to the view. Each value in the <var>$data</var> array is assigned to a variable with the name of its key. So the value of <var>$data['title']</var> in the controller is equivalent to $title in the view.<p>
-	
-<h2>Routing</h2>
-
-<p>The controller is now functioning! Point your browser to <dfn>[your-site-url]index.php/pages/view</dfn> to see your page. When you visit <dfn>index.php/pages/view/about</dfn> you'll see the about page, again including the header and footer.</p>
-
-<p>Using custom routing rules, you have the power to map any URI to any controller and method, and break free from the normal convention:
-<code>http://example.com/[controller-class]/[controller-method]/[arguments]</code></p>
-
-<p>Let's do that. Open the routing file located at <dfn>application/config/routes.php</dfn> and add the following two lines. Remove all other code that sets any element in the <var>$route</var> array.</p>
-	
-<pre>
-$route['default_controller'] = 'pages/view';
-$route['(:any)'] = 'pages/view/$1';
-</pre>
-
-<p>CodeIgniter reads its routing rules from top to bottom and routes the request to the first matching rule. Each rule is a regular expression
-(left-side) mapped to a controller and method name separated by slashes (right-side).
-When a request comes in, CodeIgniter looks for the first match, and calls the appropriate controller and method, possibly with arguments.</p>
-
-<p>More information about routing can be found in the URI Routing <a href="../general/routing.html">documentation</a>.</p>
-
-<p>Here, the second rule in the <var>$routes</var> array matches <strong>any</strong> request using the wildcard string <dfn>(:any)</dfn>.
-and passes the parameter to the view() method of the pages class.</p>
-
-<p>Now visit <dfn>index.php/about</dfn>. Did it get routed correctly to the <var>view()</var> method
-in the pages controller? Awesome!</p>

+Tutorial − Static pages
+=======================
+
+**Note:** This tutorial assumes you've downloaded CodeIgniter and
+`installed the framework <../installation/index.html>`_ in your
+development environment.
+
+The first thing you're going to do is set up a **controller** to handle
+static pages. A controller is simply a class that helps delegate work.
+It is the glue of your web application.
+
+For example, when a call is made to:
+``http://example.com/news/latest/10`` We might imagine that there is a
+controller named "news". The method being called on news would be
+"latest". The news method's job could be to grab 10 news items, and
+render them on the page. Very often in MVC, you'll see URL patterns that
+match:
+``http://example.com/[controller-class]/[controller-method]/[arguments]``
+As URL schemes become more complex, this may change. But for now, this
+is all we will need to know.
+
+Create a file at application/controllers/pages.php with the following
+code.
+
+<?php class Pages extends CI\_Controller { public function view($page =
+'home') { } }
+
+You have created a class named "pages", with a view method that accepts
+one argument named $page. The pages class is extending the
+CI\_Controller class. This means that the new pages class can access the
+methods and variables defined in the CI\_Controller class
+(system/core/Controller.php).
+
+The **controller is what will become the center of every request** to
+your web application. In very technical CodeIgniter discussions, it may
+be referred to as the *super object*. Like any php class, you refer to
+it within your controllers as $this. Referring to $this is how you will
+load libraries, views, and generally command the framework.
+
+Now you've created your first method, it's time to make some basic page
+templates. We will be creating two "views" (page templates) that act as
+our page footer and header.
+
+Create the header at application/views/templates/header.php and add the
+following code.
+
+CodeIgniter 2 Tutorial
+======================
+
+The header contains the basic HTML code that you'll want to display
+before loading the main view, together with a heading. It will also
+output the $title variable, which we'll define later in the controller.
+Now create a footer at application/views/templates/footer.php that
+includes the following code:
+
+**&copy; 2011**
+
+Adding logic to the controller
+------------------------------
+
+Earlier you set up a controller with a view() method. The method accepts
+one parameter, which is the name of the page to be loaded. The static
+page templates will be located in the application/views/pages/
+directory.
+
+In that directory, create two files named home.php and about.php. Within
+those files, type some text − anything you'd like − and save them. If
+you like to be particularly un-original, try "Hello World!".
+
+In order to load those pages, you'll have to check whether the requested
+page actually exists:
+
+::
+
+    public function view($page = 'home')
+    {
+                
+        if ( ! file_exists('application/views/pages/'.$page.'.php'))
+        {
+            // Whoops, we don't have a page for that!
+            show_404();
+        }
+        
+        $data['title'] = ucfirst($page); // Capitalize the first letter
+        
+        $this->load->view('templates/header', $data);
+        $this->load->view('pages/'.$page, $data);
+        $this->load->view('templates/footer', $data);
+
+    }
+
+Now, when the page does exist, it is loaded, including the header and
+footer, and displayed to the user. If the page doesn't exist, a "404
+Page not found" error is shown.
+
+The first line in this method checks whether the page actually exists.
+PHP's native file\_exists() function is used to check whether the file
+is where it's expected to be. show\_404() is a built-in CodeIgniter
+function that renders the default error page.
+
+In the header template, the $title variable was used to customize the
+page title. The value of title is defined in this method, but instead of
+assigning the value to a variable, it is assigned to the title element
+in the $data array.
+
+The last thing that has to be done is loading the views in the order
+they should be displayed. The second parameter in the view() method is
+used to pass values to the view. Each value in the $data array is
+assigned to a variable with the name of its key. So the value of
+$data['title'] in the controller is equivalent to $title in the view.
+
+Routing
+-------
+
+The controller is now functioning! Point your browser to
+[your-site-url]index.php/pages/view to see your page. When you visit
+index.php/pages/view/about you'll see the about page, again including
+the header and footer.
+
+Using custom routing rules, you have the power to map any URI to any
+controller and method, and break free from the normal convention:
+``http://example.com/[controller-class]/[controller-method]/[arguments]``
+
+Let's do that. Open the routing file located at
+application/config/routes.php and add the following two lines. Remove
+all other code that sets any element in the $route array.
+
+::
+
+    $route['default_controller'] = 'pages/view';
+    $route['(:any)'] = 'pages/view/$1';
+
+CodeIgniter reads its routing rules from top to bottom and routes the
+request to the first matching rule. Each rule is a regular expression
+(left-side) mapped to a controller and method name separated by slashes
+(right-side). When a request comes in, CodeIgniter looks for the first
+match, and calls the appropriate controller and method, possibly with
+arguments.
+
+More information about routing can be found in the URI Routing
+`documentation <../general/routing.html>`_.
+
+Here, the second rule in the $routes array matches **any** request using
+the wildcard string (:any). and passes the parameter to the view()
+method of the pages class.
+
+Now visit index.php/about. Did it get routed correctly to the view()
+method in the pages controller? Awesome!

-CodeIgniter 2 Tutorial
-======================
-
-Our header doesn't do anything exciting. It contains the basic HTML code
-that we will want to display before loading the main view. You can also
-see that we echo the $title variable, which we didn't define. We will
-set this variable in the Pages controller a bit later. Let's go ahead
-and create a footer at application/views/templates/footer.php that
-includes the following code.
-
-**© 2011**
-
-Adding logic to the controller
-------------------------------
-
-Now we've set up the basics so we can finally do some real programming.
-Earlier we set up our controller with a view method. Because we don't
-want to write a separate method for every page, we made the view method
-accept one parameter, the name of the page. These hard coded pages will
-be located in application/views/pages/. Create two files in this
-directory named home.php and about.php and put in some HTML content.
-
-In order to load these pages we'll have to check whether these page
-actually exists. When the page does exist, we load the view for that
-pages, including the header and footer and display it to the user. If it
-doesn't, we show a "404 Page not found" error.
-
-public function view($page = 'home') { if ( !
-file\_exists('application/views/pages/' . $page . EXT)) { show\_404(); }
-$data['title'] = ucfirst($page); $this->load->view('templates/header',
-$data); $this->load->view('pages/'.$page);
-$this->load->view('templates/footer'); }
-
-The first thing we do is checking whether the page we're looking for
-does actually exist. We use PHP's native file\_exists() to do this check
-and pass the path where the file is supposed to be. Next is the function
-show\_404(), a CodeIgniter function that renders the default error page
-and sets the appropriate HTTP headers.
-
-In the header template you saw we were using the $title variable to
-customize our page title. This is where we define the title, but instead
-of assigning the value to a variable, we assign it to the title element
-in the $data array. The last thing we need to do is loading the views in
-the order we want them to be displayed. We also pass the $data array to
-the header view to make its elements available in the header view file.
-
-Routing
--------
-
-Actually, our controller is already functioning. Point your browser to
-index.php/pages/view to see your homepage. When you visit
-index.php/pages/view/about you will see the about page, again including
-your header and footer. Now we're going to get rid of the pages/view
-part in our URI. As you may have seen, CodeIgniter does its routing by
-the class, method and parameter, separated by slashes.
-
-Open the routing file located at application/config/routes.php and add
-the following two lines. Remove all other code that sets any element in
-the $route array.
-
-$route['(:any)'] = 'pages/view/$1'; $route['default\_controller'] =
-'pages/view';
-
-CodeIgniter reads its routing rules from top to bottom and routes the
-request to the first matching rule. These routes are stored in the
-$route array where the keys represent the incoming request and the value
-the path to the method, as described above.
-
-The first rule in our $routes array matches every request - using the
-wildcard operator (:any) - and passes the value to the view method of
-the pages class we created earlier. The default controller route makes
-sure every request to the root goes to the view method as well, which
-has the first parameter set to 'home' by default.

-<h2>Version 2.0.3</h2>
-<p>Release Date: August 20, 2011</p>
-
-<ul>
-	<li>Security
-		<ul>
-			<li>An improvement was made to the MySQL and MySQLi drivers to prevent exposing a potential vector for SQL injection on sites using multi-byte character sets in the database client connection.  <p>An incompatibility in PHP versions &lt; 5.2.3 and MySQL &lt; 5.0.7 with <em>mysql_set_charset()</em> creates a situation where using multi-byte  character sets on these environments may potentially expose a SQL injection attack vector.  Latin-1, UTF-8, and other "low ASCII" character sets are unaffected on all environments.</p>  <p class="critical">If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable.</p></li>

-			<li>Scaffolding, having been deprecated for a number of versions, has been removed.</li>
-			<li>Plugins have been removed, in favor of Helpers.  The CAPTCHA plugin has been converted to a Helper and <a href="./helpers/captcha_helper.html">documented</a>.  The JavaScript calendar plugin was removed due to the ready availability of great JavaScript calendars, particularly with jQuery.</li>

-<ul>
-	<li>Libraries
-		<ul>
-			<li>Added a new <a href="libraries/form_validation.html">Form Validation Class</a>.  It simplifies setting rules and field names, supports arrays as field names, allows groups of validation rules to be saved in a config file, and adds some helper functions for use in view files.  <strong>Please note that the old Validation class is now deprecated</strong>. We will leave it in the library folder for some time so that existing applications that use it will not break, but you are encouraged to migrate to the new version.</li>
-			<li>Updated the <a href="libraries/sessions.html">Sessions class</a> so that any custom data being saved gets stored to a database rather than the session cookie (assuming you are using a database to store session data), permitting much more data to be saved.</li>
-			<li>Added the ability to store libraries in subdirectories within either the main "libraries" or the local application "libraries" folder. Please see the <a href="libraries/loader.html">Loader class</a> for more info.</li>

-	<li>Database
-		<ul>
-			<li>Improved Active Record class to allow full path column and table names:  hostname.database.table.column.  Also improved the alias handling.</li>
-			<li>Improved how table and column names are escaped and prefixed.  It now honors full path names when adding prefixes and escaping.</li>
-			<li>Added Active Record caching feature to "update" and "delete" functions.</li>
-			<li>Added removal of non-printing control characters in <kbd>escape_str()</kbd> of DB drivers that do not have native PHP escaping mechanisms (mssql, oci8, odbc), to avoid potential SQL errors, and possible sources of SQL injection.</li>
-			<li>Added port support to MySQL, MySQLi, and MS SQL database drivers.</li>

+###################################
+Open Software License ("OSL") v 3.0
+###################################
+
+This Open Software License (the "License") applies to any original work of
+authorship (the "Original Work") whose owner (the "Licensor") has placed the
+following licensing notice adjacent to the copyright notice for the Original
+Work:
+
+*Licensed under the Open Software License version 3.0*
+
+
+*****************************
+1) Grant of Copyright License
+*****************************
+
+Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
+license, for the duration of the copyright, to do the following:
+
+	*a)* to reproduce the Original Work in copies, either alone or as part of
+	a collective work;
+
+	*b)* to translate, adapt, alter, transform, modify, or arrange the
+	Original Work, thereby creating derivative works ("Derivative Works")
+	based upon the Original Work;
+
+	*c)* to distribute or communicate copies of the Original Work and
+	Derivative Works to the public, *with the proviso that copies of Original
+	Work or Derivative Works that You distribute or communicate shall be
+	licensed under this Open Software License*;
+
+	*d)* to perform the Original Work publicly; and
+
+	*e)* to display the Original Work publicly.
+
+
+**************************
+2) Grant of Patent License
+**************************
+
+Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
+license, under patent claims owned or controlled by the Licensor that are
+embodied in the Original Work as furnished by the Licensor, for the duration
+of the patents, to make, use, sell, offer for sale, have made, and import the
+Original Work and Derivative Works.
+
+
+*******************************
+3) Grant of Source Code License
+*******************************
+
+The term "Source Code" means the preferred form of the Original Work for
+making modifications to it and all available documentation describing how to
+modify the Original Work. Licensor agrees to provide a machine-readable copy
+of the Source Code of the Original Work along with each copy of the Original
+Work that Licensor distributes. Licensor reserves the right to satisfy this
+obligation by placing a machine-readable copy of the Source Code in an
+information repository reasonably calculated to permit inexpensive and
+convenient access by You for as long as Licensor continues to distribute the
+Original Work.
+
+
+********************************
+4) Exclusions From License Grant
+********************************
+
+Neither the names of Licensor, nor the names of any contributors to the
+Original Work, nor any of their trademarks or service marks, may be used to
+endorse or promote products derived from this Original Work without express
+prior permission of the Licensor. Except as expressly stated herein, nothing
+in this License grants any license to Licensor's trademarks, copyrights,
+patents, trade secrets or any other intellectual property. No patent license
+is granted to make, use, sell, offer for sale, have made, or import
+embodiments of any patent claims other than the licensed claims defined in
+Section 2) No license is granted to the trademarks of Licensor even if such
+marks are included in the Original Work. Nothing in this License shall be
+interpreted to prohibit Licensor from licensing under terms different from
+this License any Original Work that Licensor otherwise would have a right to
+license.
+
+
+**********************
+5) External Deployment
+**********************
+
+The term "External Deployment" means the use, distribution, or communication
+of the Original Work or Derivative Works in any way such that the Original
+Work or Derivative Works may be used by anyone other than You, whether those
+works are distributed or communicated to those persons or made available as an
+application intended for use over a network. As an express condition for the
+grants of license hereunder, You must treat any External Deployment by You of
+the Original Work or a Derivative Work as a distribution under section 1(c).
+
+
+*********************
+6) Attribution Rights
+*********************
+
+You must retain, in the Source Code of any Derivative Works that You create,
+all copyright, patent, or trademark notices from the Source Code of the
+Original Work, as well as any notices of licensing and any descriptive text
+identified therein as an "Attribution Notice." You must cause the Source Code
+for any Derivative Works that You create to carry a prominent Attribution
+Notice reasonably calculated to inform recipients that You have modified the
+Original Work.
+
+
+****************************************************
+7) Warranty of Provenance and Disclaimer of Warranty
+****************************************************
+
+Licensor warrants that the copyright in and to the Original Work and the
+patent rights granted herein by Licensor are owned by the Licensor or are
+sublicensed to You under the terms of this License with the permission of the
+contributor(s) of those copyrights and patent rights. Except as expressly
+stated in the immediately preceding sentence, the Original Work is provided
+under this License on an "AS IS" BASIS and WITHOUT WARRANTY, either express or
+implied, including, without limitation, the warranties of non-infringement,
+merchantability or fitness for a particular purpose. THE ENTIRE RISK AS TO THE
+QUALITY OF THE ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY
+constitutes an essential part of this License. No license to the Original Work
+is granted by this License except under this disclaimer.
+
+
+**************************
+8) Limitation of Liability
+**************************
+
+Under no circumstances and under no legal theory, whether in tort (including
+negligence), contract, or otherwise, shall the Licensor be liable to anyone
+for any indirect, special, incidental, or consequential damages of any
+character arising as a result of this License or the use of the Original Work
+including, without limitation, damages for loss of goodwill, work stoppage,
+computer failure or malfunction, or any and all other commercial damages or
+losses. This limitation of liability shall not apply to the extent applicable
+law prohibits such limitation.
+
+
+*****************************
+9) Acceptance and Termination
+*****************************
+
+If, at any time, You expressly assented to this License, that assent indicates
+your clear and irrevocable acceptance of this License and all of its terms and
+conditions. If You distribute or communicate copies of the Original Work or a
+Derivative Work, You must make a reasonable effort under the circumstances to
+obtain the express assent of recipients to the terms of this License. This
+License conditions your rights to undertake the activities listed in Section
+1, including your right to create Derivative Works based upon the Original
+Work, and doing so without honoring these terms and conditions is prohibited
+by copyright law and international treaty. Nothing in this License is intended
+to affect copyright exceptions and limitations (including "fair use" or "fair
+dealing"). This License shall terminate immediately and You may no longer
+exercise any of the rights granted to You by this License upon your failure to
+honor the conditions in Section 1(c).
+
+
+*********************************
+10) Termination for Patent Action
+*********************************
+
+This License shall terminate automatically and You may no longer exercise any
+of the rights granted to You by this License as of the date You commence an
+action, including a cross-claim or counterclaim, against Licensor or any
+licensee alleging that the Original Work infringes a patent. This termination
+provision shall not apply for an action alleging patent infringement by
+combinations of the Original Work with other software or hardware.
+
+
+*****************************************
+11) Jurisdiction, Venue and Governing Law
+*****************************************
+
+Any action or suit relating to this License may be brought only in the courts
+of a jurisdiction wherein the Licensor resides or in which Licensor conducts
+its primary business, and under the laws of that jurisdiction excluding its
+conflict-of-law provisions. The application of the United Nations Convention
+on Contracts for the International Sale of Goods is expressly excluded. Any
+use of the Original Work outside the scope of this License or after its
+termination shall be subject to the requirements and penalties of copyright or
+patent law in the appropriate jurisdiction. This section shall survive the
+termination of this License.
+
+
+*******************
+12) Attorneys' Fees
+*******************
+
+In any action to enforce the terms of this License or seeking damages relating
+thereto, the prevailing party shall be entitled to recover its costs and
+expenses, including, without limitation, reasonable attorneys' fees and costs
+incurred in connection with such action, including any appeal of such action.
+This section shall survive the termination of this License.
+
+
+*****************
+13) Miscellaneous
+*****************
+
+If any provision of this License is held to be unenforceable, such provision
+shall be reformed only to the extent necessary to make it enforceable.
+
+
+***************************************
+14) Definition of "You" in This License
+***************************************
+
+"You" throughout this License, whether in upper or lower case, means an
+individual or a legal entity exercising rights under, and complying with all
+of the terms of, this License. For legal entities, "You" includes any entity
+that controls, is controlled by, or is under common control with you. For
+purposes of this definition, "control" means (i) the power, direct or
+indirect, to cause the direction or management of such entity, whether by
+contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the
+outstanding shares, or (iii) beneficial ownership of such entity.
+
+
+****************
+15) Right to Use
+****************
+
+You may use the Original Work in all ways not otherwise restricted or
+conditioned by this License or by law, and Licensor promises not to interfere
+with or be responsible for such uses by You.
+
+
+********************************
+16) Modification of This License
+********************************
+
+This License is Copyright © 2005 Lawrence Rosen. Permission is granted to
+copy, distribute, or communicate this License without modification. Nothing in
+this License permits You to modify this License as applied to the Original
+Work or to Derivative Works. However, You may modify the text of this License
+and copy, distribute or communicate your modified version (the "Modified
+License") and apply it to other original works of authorship subject to the
+following conditions: (i) You may not indicate in any way that your Modified
+License is the "Open Software License" or "OSL" and you may not use those
+names in the name of your Modified License; (ii) You must replace the notice
+specified in the first paragraph above with the notice "Licensed under <insert
+your license name here>" or with a notice of your own that is not confusingly
+similar to the notice in this License; and (iii) You may not claim that your
+original works are open source software unless your Modified License has been
+approved by Open Source Initiative (OSI) and You comply with its license
+review and certification process.

+2) Grant of Patent License. Licensor grants You a worldwide, royalty-free,
+non-exclusive, sublicensable license, under patent claims owned or controlled
+by the Licensor that are embodied in the Original Work as furnished by the
+Licensor, for the duration of the patents, to make, use, sell, offer for sale,
+have made, and import the Original Work and Derivative Works.
+
+3) Grant of Source Code License. The term "Source Code" means the preferred
+form of the Original Work for making modifications to it and all available
+documentation describing how to modify the Original Work. Licensor agrees to
+provide a machine-readable copy of the Source Code of the Original Work along

+reserves the right to satisfy this obligation by placing a machine-readable
+copy of the Source Code in an information repository reasonably calculated to
+permit inexpensive and convenient access by You for as long as Licensor
+continues to distribute the Original Work.
+
+4) Exclusions From License Grant. Neither the names of Licensor, nor the names
+of any contributors to the Original Work, nor any of their trademarks or
+service marks, may be used to endorse or promote products derived from this
+Original Work without express prior permission of the Licensor. Except as
+expressly stated herein, nothing in this License grants any license to
+Licensor's trademarks, copyrights, patents, trade secrets or any other
+intellectual property. No patent license is granted to make, use, sell, offer
+for sale, have made, or import embodiments of any patent claims other than the
+licensed claims defined in Section 2. No license is granted to the trademarks
+of Licensor even if such marks are included in the Original Work. Nothing in
+this License shall be interpreted to prohibit Licensor from licensing under
+terms different from this License any Original Work that Licensor otherwise
+would have a right to license.
+
+5) External Deployment. The term "External Deployment" means the use,
+distribution, or communication of the Original Work or Derivative Works in any
+way such that the Original Work or Derivative Works may be used by anyone
+other than You, whether those works are distributed or communicated to those
+persons or made available as an application intended for use over a network.
+As an express condition for the grants of license hereunder, You must treat
+any External Deployment by You of the Original Work or a Derivative Work as a
+distribution under section 1(c).
+
+6) Attribution Rights. You must retain, in the Source Code of any Derivative
+Works that You create, all copyright, patent, or trademark notices from the
+Source Code of the Original Work, as well as any notices of licensing and any
+descriptive text identified therein as an "Attribution Notice." You must cause
+the Source Code for any Derivative Works that You create to carry a prominent
+Attribution Notice reasonably calculated to inform recipients that You have
+modified the Original Work.
+
+7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that
+the copyright in and to the Original Work and the patent rights granted herein
+by Licensor are owned by the Licensor or are sublicensed to You under the
+terms of this License with the permission of the contributor(s) of those
+copyrights and patent rights. Except as expressly stated in the immediately
+preceding sentence, the Original Work is provided under this License on an "AS
+IS" BASIS and WITHOUT WARRANTY, either express or implied, including, without
+limitation, the warranties of non-infringement, merchantability or fitness for
+a particular purpose. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK
+IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this
+License. No license to the Original Work is granted by this License except
+under this disclaimer.
+
+8) Limitation of Liability. Under no circumstances and under no legal theory,
+whether in tort (including negligence), contract, or otherwise, shall the
+Licensor be liable to anyone for any indirect, special, incidental, or
+consequential damages of any character arising as a result of this License or
+the use of the Original Work including, without limitation, damages for loss
+of goodwill, work stoppage, computer failure or malfunction, or any and all
+other commercial damages or losses. This limitation of liability shall not
+apply to the extent applicable law prohibits such limitation.
+
+9) Acceptance and Termination. If, at any time, You expressly assented to this
+License, that assent indicates your clear and irrevocable acceptance of this
+License and all of its terms and conditions. If You distribute or communicate
+copies of the Original Work or a Derivative Work, You must make a reasonable
+effort under the circumstances to obtain the express assent of recipients to
+the terms of this License. This License conditions your rights to undertake
+the activities listed in Section 1, including your right to create Derivative
+Works based upon the Original Work, and doing so without honoring these terms
+and conditions is prohibited by copyright law and international treaty.
+Nothing in this License is intended to affect copyright exceptions and
+limitations (including "fair use" or "fair dealing"). This License shall
+terminate immediately and You may no longer exercise any of the rights granted
+to You by this License upon your failure to honor the conditions in Section
+1(c).
+
+10) Termination for Patent Action. This License shall terminate automatically
+and You may no longer exercise any of the rights granted to You by this
+License as of the date You commence an action, including a cross-claim or
+counterclaim, against Licensor or any licensee alleging that the Original Work
+infringes a patent. This termination provision shall not apply for an action
+alleging patent infringement by combinations of the Original Work with other
+software or hardware.
+
+11) Jurisdiction, Venue and Governing Law. Any action or suit relating to this
+License may be brought only in the courts of a jurisdiction wherein the
+Licensor resides or in which Licensor conducts its primary business, and under
+the laws of that jurisdiction excluding its conflict-of-law provisions. The
+application of the United Nations Convention on Contracts for the
+International Sale of Goods is expressly excluded. Any use of the Original
+Work outside the scope of this License or after its termination shall be
+subject to the requirements and penalties of copyright or patent law in the
+appropriate jurisdiction. This section shall survive the termination of this
+License.
+
+12) Attorneys' Fees. In any action to enforce the terms of this License or
+seeking damages relating thereto, the prevailing party shall be entitled to
+recover its costs and expenses, including, without limitation, reasonable
+attorneys' fees and costs incurred in connection with such action, including
+any appeal of such action. This section shall survive the termination of this
+License.
+
+13) Miscellaneous. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent necessary
+to make it enforceable.
+
+14) Definition of "You" in This License. "You" throughout this License,
+whether in upper or lower case, means an individual or a legal entity
+exercising rights under, and complying with all of the terms of, this License.
+For legal entities, "You" includes any entity that controls, is controlled by,
+or is under common control with you. For purposes of this definition,
+"control" means (i) the power, direct or indirect, to cause the direction or
+management of such entity, whether by contract or otherwise, or (ii) ownership
+of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial
+ownership of such entity.
+
+15) Right to Use. You may use the Original Work in all ways not otherwise
+restricted or conditioned by this License or by law, and Licensor promises not
+to interfere with or be responsible for such uses by You.
+
+16) Modification of This License. This License is Copyright © 2005 Lawrence
+Rosen. Permission is granted to copy, distribute, or communicate this License
+without modification. Nothing in this License permits You to modify this
+License as applied to the Original Work or to Derivative Works. However, You
+may modify the text of this License and copy, distribute or communicate your
+modified version (the "Modified License") and apply it to other original works
+of authorship subject to the following conditions: (i) You may not indicate in
+any way that your Modified License is the "Open Software License" or "OSL" and

+must replace the notice specified in the first paragraph above with the notice
+"Licensed under <insert your license name here>" or with a notice of your own
+that is not confusingly similar to the notice in this License; and (iii) You

These contributions are made in the form of Issues or [Pull Requests](http://help.github.com/send-pull-requests/) on the [EllisLab CodeIgniter repository](https://github.com/EllisLab/CodeIgniter) on GitHub.
-
-Issues are a quick way to point out a bug. If you find a bug or documentation error in CodeIgniter then please check a few things first:
-
-     
-    There is not already an open Issue
-    The issue has already been fixed (check the develop branch, or look for closed Issues)
-    Is it something really obvious that you fix it yourself?
-
-Reporting issues is helpful but an even better approach is to send a Pull Request, which is done by “Forking� the main repository and committing to your own copy. This will require you to use the version control system called Git.
-
-Guidelines
-----------
-
-Before we look into how, here are the guidelines. If your Pull Requests fail to pass these guidelines it will be declined and you will need to re-submit when you’ve made the changes. This might sound a bit tough, but it is required for us to maintain quality of the code-base.
-
-PHP Style: All code must meet the [Style Guide](http://codeigniter.com/user_guide/general/styleguide.html), which is essentially the [Allman indent style](http://en.wikipedia.org/wiki/Indent_style#Allman_style), underscores and readable operators. This makes certain that all code is the same format as the existing code and means it will be as readable as possible.
-
-Documentation: If you change anything that requires a change to documentation then you will need to add it. New classes, methods, parameters, changing default values, etc are all things that will require a change to documentation. The change-log must also be updated for every change. Also PHPDoc blocks must be maintained.
-
-Compatibility: CodeIgniter is compatible with PHP 5.1.6 so all code supplied must stick to this requirement. If PHP 5.2 or 5.3 functions or features are used then there must be a fallback for PHP 5.1.6.
-
-Branching: CodeIgniter uses the [Git-Flow](http://nvie.com/posts/a-successful-git-branching-model/) branching model which requires all pull requests to be sent to the “develop� branch. This is where the next planned version will be developed. The “master� branch will always contain the latest stable version and is kept clean so a “hotfix� (e.g: an emergency security patch) can be applied to master to create a new version, without worrying about other features holding it up. For this reason all commits need to be made to “develop� and any sent to “master� will be closed automatically. If you have multiple changes to submit, please place all changes into their own branch on your fork.
-
-One thing at a time: A pull request should only contain one change. That does not mean only one commit, but one change - however many commits it took. The reason for this is that if you change X and Y but send a pull request for both at the same time, we might really want X but disagree with Y, meaning we cannot merge the request. Using the Git-Flow branching model you can create new branches for both of these features and send two requests.
-
-How-to Guide
-------------
-
-There are two ways to make changes, the easy way and the hard way. Either way you will need to [create a GitHub account](https://github.com/signup/free).
-
-Easy way
-GitHub allows in-line editing of files for making simple typo changes and quick-fixes. This is not the best way as you are unable to test the code works. If you do this you could be introducing syntax errors, etc, but for a Git-phobic user this is good for a quick-fix.
-
-Hard way
-The best way to contribute is to “clone� your fork of CodeIgniter to your development area. That sounds like some jargon, but “forking� on GitHub means “making a copy of that repo to your account� and “cloning� means “copying that code to your environment so you can work on it�.
-
-    Set up Git (Windows, Mac & Linux)
-    Go to the CodeIgniter repo
-    Fork it
-    Clone your CodeIgniter repo: git@github.com:<your-name>/CodeIgniter.git
-    Checkout the “develop� branch At this point you are ready to start making changes. 
-	Fix existing bugs on the Issue tracker after taking a look to see nobody else is working on them.
-    Commit the files
-    Push your develop branch to your fork
-    Send a pull request http://help.github.com/send-pull-requests/
-
-The Reactor Engineers will now be alerted about the change and at least one of the team will respond. If your change fails to meet the guidelines it will be bounced, or feedback will be provided to help you improve it.
-
-Once the Reactor Engineer handling your pull request is happy with it they will post it to the internal EllisLab discussion area to be double checked by the other Engineers and EllisLab developers. If nobody has a problem with the change then it will be merged into develop and will be part of the next release.
-Keeping your fork up-to-date
-
-Unlike systems like Subversion, Git can have multiple remotes. A remote is the name for a URL of a Git repository. By default your fork will have a remote named “origin� which points to your fork, but you can add another remote named “codeigniter� which points to git://github.com/EllisLab/CodeIgniter.git. This is a read-only remote but you can pull from this develop branch to update your own.
-
-If you are using command-line you can do the following:
-
-    git remote add codeigniter git://github.com/EllisLab/CodeIgniter.git
-	git pull codeigniter develop
-	git push origin develop
-
-Now your fork is up to date. This should be done regularly, or before you send a pull request at least.

+What is CodeIgniter
+###################
+
+CodeIgniter is an Application Development Framework - a toolkit - for people
+who build web sites using PHP. Its goal is to enable you to develop projects
+much faster than you could if you were writing code from scratch, by providing
+a rich set of libraries for commonly needed tasks, as well as a simple
+interface and logical structure to access these libraries. CodeIgniter lets
+you creatively focus on your project by minimizing the amount of code needed
+for a given task.
+

+Before we look into how, here are the guidelines. If your Pull Requests fail
+to pass these guidelines it will be declined and you will need to re-submit
+when you’ve made the changes. This might sound a bit tough, but it is required
+for us to maintain quality of the code-base.
+
+PHP Style
+=========
+
+All code must meet the `Style Guide
+<http://codeigniter.com/user_guide/general/styleguide.html>`_, which is
+essentially the `Allman indent style
+<http://en.wikipedia.org/wiki/Indent_style#Allman_style>`_, underscores and
+readable operators. This makes certain that all code is the same format as the
+existing code and means it will be as readable as possible.
+

+=============
+
+If you change anything that requires a change to documentation then you will
+need to add it. New classes, methods, parameters, changing default values, etc
+are all things that will require a change to documentation. The change-log
+must also be updated for every change. Also PHPDoc blocks must be maintained.
+
+Compatibility
+=============
+
+CodeIgniter is compatible with PHP 5.1.6 so all code supplied must stick to
+this requirement. If PHP 5.2 or 5.3 functions or features are used then there
+must be a fallback for PHP 5.1.6.
+
+Branching
+=========
+
+CodeIgniter uses the `Git-Flow
+<http://nvie.com/posts/a-successful-git-branching-model/>`_ branching model
+which requires all pull requests to be sent to the "develop" branch. This is
+where the next planned version will be developed. The "master" branch will
+always contain the latest stable version and is kept clean so a "hotfix" (e.g:
+an emergency security patch) can be applied to master to create a new version,
+without worrying about other features holding it up. For this reason all
+commits need to be made to "develop" and any sent to "master" will be closed
+automatically. If you have multiple changes to submit, please place all
+changes into their own branch on your fork.

+cannot merge the request. Using the Git-Flow branching model you can create
+new branches for both of these features and send two requests.

+Open Software License ("OSL") v 3.0
+###################################
+
+This Open Software License (the "License") applies to any original work of
+authorship (the "Original Work") whose owner (the "Licensor") has placed the
+following licensing notice adjacent to the copyright notice for the Original
+Work:
+
+*Licensed under the Open Software License version 3.0*
+
+
+*****************************
+1) Grant of Copyright License
+*****************************
+
+Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
+license, for the duration of the copyright, to do the following:
+
+	*a)* to reproduce the Original Work in copies, either alone or as part of
+	a collective work;
+
+	*b)* to translate, adapt, alter, transform, modify, or arrange the
+	Original Work, thereby creating derivative works ("Derivative Works")
+	based upon the Original Work;
+
+	*c)* to distribute or communicate copies of the Original Work and
+	Derivative Works to the public, *with the proviso that copies of Original
+	Work or Derivative Works that You distribute or communicate shall be
+	licensed under this Open Software License*;
+
+	*d)* to perform the Original Work publicly; and
+
+	*e)* to display the Original Work publicly.
+
+
+**************************
+2) Grant of Patent License
+**************************
+
+Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
+license, under patent claims owned or controlled by the Licensor that are
+embodied in the Original Work as furnished by the Licensor, for the duration
+of the patents, to make, use, sell, offer for sale, have made, and import the
+Original Work and Derivative Works.
+
+
+*******************************
+3) Grant of Source Code License
+*******************************
+
+The term "Source Code" means the preferred form of the Original Work for
+making modifications to it and all available documentation describing how to
+modify the Original Work. Licensor agrees to provide a machine-readable copy
+of the Source Code of the Original Work along with each copy of the Original
+Work that Licensor distributes. Licensor reserves the right to satisfy this
+obligation by placing a machine-readable copy of the Source Code in an
+information repository reasonably calculated to permit inexpensive and
+convenient access by You for as long as Licensor continues to distribute the
+Original Work.
+
+
+********************************
+4) Exclusions From License Grant
+********************************
+
+Neither the names of Licensor, nor the names of any contributors to the
+Original Work, nor any of their trademarks or service marks, may be used to
+endorse or promote products derived from this Original Work without express
+prior permission of the Licensor. Except as expressly stated herein, nothing
+in this License grants any license to Licensor's trademarks, copyrights,
+patents, trade secrets or any other intellectual property. No patent license
+is granted to make, use, sell, offer for sale, have made, or import
+embodiments of any patent claims other than the licensed claims defined in
+Section 2) No license is granted to the trademarks of Licensor even if such
+marks are included in the Original Work. Nothing in this License shall be
+interpreted to prohibit Licensor from licensing under terms different from
+this License any Original Work that Licensor otherwise would have a right to
+license.
+
+
+**********************
+5) External Deployment
+**********************
+
+The term "External Deployment" means the use, distribution, or communication
+of the Original Work or Derivative Works in any way such that the Original
+Work or Derivative Works may be used by anyone other than You, whether those
+works are distributed or communicated to those persons or made available as an
+application intended for use over a network. As an express condition for the
+grants of license hereunder, You must treat any External Deployment by You of
+the Original Work or a Derivative Work as a distribution under section 1(c).
+
+
+*********************
+6) Attribution Rights
+*********************
+
+You must retain, in the Source Code of any Derivative Works that You create,
+all copyright, patent, or trademark notices from the Source Code of the
+Original Work, as well as any notices of licensing and any descriptive text
+identified therein as an "Attribution Notice." You must cause the Source Code
+for any Derivative Works that You create to carry a prominent Attribution
+Notice reasonably calculated to inform recipients that You have modified the
+Original Work.
+
+
+****************************************************
+7) Warranty of Provenance and Disclaimer of Warranty
+****************************************************
+
+Licensor warrants that the copyright in and to the Original Work and the
+patent rights granted herein by Licensor are owned by the Licensor or are
+sublicensed to You under the terms of this License with the permission of the
+contributor(s) of those copyrights and patent rights. Except as expressly
+stated in the immediately preceding sentence, the Original Work is provided
+under this License on an "AS IS" BASIS and WITHOUT WARRANTY, either express or
+implied, including, without limitation, the warranties of non-infringement,
+merchantability or fitness for a particular purpose. THE ENTIRE RISK AS TO THE
+QUALITY OF THE ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY
+constitutes an essential part of this License. No license to the Original Work
+is granted by this License except under this disclaimer.
+
+
+**************************
+8) Limitation of Liability
+**************************
+
+Under no circumstances and under no legal theory, whether in tort (including
+negligence), contract, or otherwise, shall the Licensor be liable to anyone
+for any indirect, special, incidental, or consequential damages of any
+character arising as a result of this License or the use of the Original Work
+including, without limitation, damages for loss of goodwill, work stoppage,
+computer failure or malfunction, or any and all other commercial damages or
+losses. This limitation of liability shall not apply to the extent applicable
+law prohibits such limitation.
+
+
+*****************************
+9) Acceptance and Termination
+*****************************
+
+If, at any time, You expressly assented to this License, that assent indicates
+your clear and irrevocable acceptance of this License and all of its terms and
+conditions. If You distribute or communicate copies of the Original Work or a
+Derivative Work, You must make a reasonable effort under the circumstances to
+obtain the express assent of recipients to the terms of this License. This
+License conditions your rights to undertake the activities listed in Section
+1, including your right to create Derivative Works based upon the Original
+Work, and doing so without honoring these terms and conditions is prohibited
+by copyright law and international treaty. Nothing in this License is intended
+to affect copyright exceptions and limitations (including "fair use" or "fair
+dealing"). This License shall terminate immediately and You may no longer
+exercise any of the rights granted to You by this License upon your failure to
+honor the conditions in Section 1(c).
+
+
+*********************************
+10) Termination for Patent Action
+*********************************
+
+This License shall terminate automatically and You may no longer exercise any
+of the rights granted to You by this License as of the date You commence an
+action, including a cross-claim or counterclaim, against Licensor or any
+licensee alleging that the Original Work infringes a patent. This termination
+provision shall not apply for an action alleging patent infringement by
+combinations of the Original Work with other software or hardware.
+
+
+*****************************************
+11) Jurisdiction, Venue and Governing Law
+*****************************************
+
+Any action or suit relating to this License may be brought only in the courts
+of a jurisdiction wherein the Licensor resides or in which Licensor conducts
+its primary business, and under the laws of that jurisdiction excluding its
+conflict-of-law provisions. The application of the United Nations Convention
+on Contracts for the International Sale of Goods is expressly excluded. Any
+use of the Original Work outside the scope of this License or after its
+termination shall be subject to the requirements and penalties of copyright or
+patent law in the appropriate jurisdiction. This section shall survive the
+termination of this License.
+
+
+*******************
+12) Attorneys' Fees
+*******************
+
+In any action to enforce the terms of this License or seeking damages relating
+thereto, the prevailing party shall be entitled to recover its costs and
+expenses, including, without limitation, reasonable attorneys' fees and costs
+incurred in connection with such action, including any appeal of such action.
+This section shall survive the termination of this License.
+
+
+*****************
+13) Miscellaneous
+*****************
+
+If any provision of this License is held to be unenforceable, such provision
+shall be reformed only to the extent necessary to make it enforceable.
+
+
+***************************************
+14) Definition of "You" in This License
+***************************************
+
+"You" throughout this License, whether in upper or lower case, means an
+individual or a legal entity exercising rights under, and complying with all
+of the terms of, this License. For legal entities, "You" includes any entity
+that controls, is controlled by, or is under common control with you. For
+purposes of this definition, "control" means (i) the power, direct or
+indirect, to cause the direction or management of such entity, whether by
+contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the
+outstanding shares, or (iii) beneficial ownership of such entity.
+
+
+****************
+15) Right to Use
+****************
+
+You may use the Original Work in all ways not otherwise restricted or
+conditioned by this License or by law, and Licensor promises not to interfere
+with or be responsible for such uses by You.
+
+
+********************************
+16) Modification of This License
+********************************
+
+This License is Copyright © 2005 Lawrence Rosen. Permission is granted to
+copy, distribute, or communicate this License without modification. Nothing in
+this License permits You to modify this License as applied to the Original
+Work or to Derivative Works. However, You may modify the text of this License
+and copy, distribute or communicate your modified version (the "Modified
+License") and apply it to other original works of authorship subject to the
+following conditions: (i) You may not indicate in any way that your Modified

+names in the name of your Modified License; (ii) You must replace the notice
+specified in the first paragraph above with the notice "Licensed under <insert
+your license name here>" or with a notice of your own that is not confusingly

Subject: auto_link() learned to recognize more URLs

Problem:
auto_link() only works on URLs that are preceded by a new line, space, or open parentheses. As a result the URL in the string below would be missed.

'Google<br />http://www.google.com/'

Solution:
Add a word boundary to the list of features that can precede a URL.

Subject: The DB_driver can now use failover databases if specified

The DB_driver can now use failover databases if specified.
If the main connection shouldn't connect for some reason the DB_driver will now try to connect to specified connections in the failover config.

Example config:
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = '';
$db['default']['password'] = '';

Subject: The DB_driver can now use failover databases if specified

The DB_driver can now use failover databases if specified.
If the main connection shouldn't connect for some reason the DB_driver will now try to connect to specified connections in the failover config.

Example config:
$db['default']['hostname'] = 'localhost';
$db['default']['username'] = '';
$db['default']['password'] = '';
$db['default']['database'] = '';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;
$db['default']['failover'] = array();

$db['default']['failover'][0]['hostname'] = 'localhost1';
$db['default']['failover'][0]['username'] = '';
$db['default']['failover'][0]['password'] = '';
$db['default']['failover'][0]['database'] = '';
$db['default']['failover'][0]['dbdriver'] = 'mysql';
$db['default']['failover'][0]['dbprefix'] = '';
$db['default']['failover'][0]['pconnect'] = TRUE;

$db['default']['failover'][0]['cache_on'] = FALSE;
$db['default']['failover'][0]['cachedir'] = '';
$db['default']['failover'][0]['char_set'] = 'utf8';
$db['default']['failover'][0]['dbcollat'] = 'utf8_general_ci';
$db['default']['failover'][0]['swap_pre'] = '';
$db['default']['failover'][0]['autoinit'] = TRUE;
$db['default']['failover'][0]['stricton'] = FALSE;
$db['default']['failover'][0]['failover'] = array();

$db['default']['failover'][1]['hostname'] = 'localhost2';
$db['default']['failover'][1]['username'] = '';
$db['default']['failover'][1]['password'] = '';
$db['default']['failover'][1]['database'] = '';
$db['default']['failover'][1]['dbdriver'] = 'mysql';

Subject: CodeIgniter ignores the set config value for Maximum Execution Time,
 overwriting it with its own value of 300 seconds. Whilst this is sensible in
 the vast majority of situations (browsers), when running a script from CLI,
 it is likely that execution times may need to be longer. Therefore, don't
 override the time limit if being run from the CLI - instead default back to
 PHP's own configuration.

+#############################
+Upgrading from 2.1.0 to 3.0.0
+#############################
+
+.. note:: These upgrade notes are for a version that is yet to be released.
+
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace all files and directories in your "system" folder and replace
+your index.php file. If any modifications were made to your index.php
+they will need to be made fresh in this new one.
+
+Step 2: Change References to the SHA Library
+============================================
+
+The previously deprecated SHA library has been removed in CodeIgniter 3.0.
+Alter your code to use the native `sha1()` PHP function to generate a sha1 hash.
+
+Additionally, the `sha1()` method in the :doc:`Encryption Library <libraries/encryption>` library has been removed.
+
+
+.. note:: If you have any custom developed files in these folders please
+	make copies of them first.

Subject: added query grouping to Active Record

this is a feature that has been lacking for a very long time. lots of people complained
about it over the years, but it never got added so you'd have to resort to handcrafted
queries when you needed this feature.

This is a port of code from DataMapper, in use since CI 1.6.

 -  Fixed a bug (#696) - make oci_execute calls inside num_rows non-committing, since they are only there to reset which row is next in line for oci_fetch calls and thus don't need to be committed.
 -  Fixed a bug (#406) - sqlsrv DB driver not reuturning resource on <samp>db_pconnect()</samp>.
 -  Fixed a bug in CI_Image_lib::gd_loaded() where it was possible for the script execution to end or a PHP E_WARNING message to be emitted.

 	 -  Added support for 3-length hex color values for wm_font_color and wm_shadow_color properties, as well as validation for them.
 	 -  Class properties wm_font_color, wm_shadow_color and wm_use_drop_shadow are now protected, to avoid breaking the text_watermark() method
 	    if they are set manually after initialization.
+	 -  If property maintain_ratio is set to TRUE, image_reproportion() now doesn't need both width and height to be specified.
    -  Minor speed optimizations and method & property visibility declarations in the Calendar Library.
    -  Removed SHA1 function in the :doc:`Encryption Library <libraries/encryption>`.
    -  Added $config['csrf_regeneration'] to the CSRF protection in the :doc:`Security library <libraries/security>`, which makes token regeneration optional.

Subject: It appears the Security class has been added to the system/core
 folder and is loaded automatically as well. Using
 $this->load->library('security'); in controllers currently returns FALSE, yet
 you might not notice because the Security class is already loaded. I
 discovered this because of a custom Loader class I was using returned an
 error when loading the Security class.

-###################
-Active Record Class
-###################
-
-CodeIgniter uses a modified version of the Active Record Database
-Pattern. This pattern allows information to be retrieved, inserted, and
-updated in your database with minimal scripting. In some cases only one
-or two lines of code are necessary to perform a database action.
-CodeIgniter does not require that each database table be its own class
-file. It instead provides a more simplified interface.
-
-Beyond simplicity, a major benefit to using the Active Record features
-is that it allows you to create database independent applications, since
-the query syntax is generated by each database adapter. It also allows
-for safer queries, since the values are escaped automatically by the
-system.
-
-.. note:: If you intend to write your own queries you can disable this
-	class in your database config file, allowing the core database library
-	and adapter to utilize fewer resources.
-
-.. contents:: Page Contents
-
-**************
-Selecting Data
-**************
-
-The following functions allow you to build SQL **SELECT** statements.
-
-$this->db->get()
-================
-
-Runs the selection query and returns the result. Can be used by itself
-to retrieve all records from a table::
-
-	$query = $this->db->get('mytable');  // Produces: SELECT * FROM mytable
-
-The second and third parameters enable you to set a limit and offset
-clause::
-
-	$query = $this->db->get('mytable', 10, 20);
-	// Produces: SELECT * FROM mytable LIMIT 20, 10 (in MySQL. Other databases have slightly different syntax)
-
-You'll notice that the above function is assigned to a variable named
-$query, which can be used to show the results::
-
-	$query = $this->db->get('mytable');
-
-	foreach ($query->result() as $row)
-	{
-		echo $row->title;
-	}
-
-Please visit the :doc:`result functions <results>` page for a full
-discussion regarding result generation.
-
-$this->db->get_compiled_select()
-================================
-
-Compiles the selection query just like `$this->db->get()`_ but does not *run*
-the query. This method simply returns the SQL query as a string.
-
-Example::
-
-	$sql = $this->db->get_compiled_select('mytable');
-	echo $sql;
-
-	// Produces string: SELECT * FROM mytable
-
-The second parameter enables you to set whether or not the active record query
-will be reset (by default it will be&mdash;just like `$this->db->get()`)::
-
-	echo $this->db->limit(10,20)->get_compiled_select('mytable', FALSE);
-	// Produces string: SELECT * FROM mytable LIMIT 20, 10
-	// (in MySQL. Other databases have slightly different syntax)
-
-	echo $this->db->select('title, content, date')->get_compiled_select();
-
-	// Produces string: SELECT title, content, date FROM mytable
-
-The key thing to notice in the above example is that the second query did not
-utilize `$this->db->from()`_ and did not pass a table name into the first
-parameter. The reason for this outcome is because the query has not been
-executed using `$this->db->get()`_ which resets values or reset directly
-using `$this->db->reset_query()`_.
-
-
-$this->db->get_where()
-======================
-
-Identical to the above function except that it permits you to add a
-"where" clause in the second parameter, instead of using the db->where()
-function::
-
-	$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);
-
-Please read the about the where function below for more information.
-
-.. note:: get_where() was formerly known as getwhere(), which has been removed
-
-$this->db->select()
-===================
-
-Permits you to write the SELECT portion of your query::
-
-	$this->db->select('title, content, date');
-	$query = $this->db->get('mytable');  // Produces: SELECT title, content, date FROM mytable
-
-
-.. note:: If you are selecting all (\*) from a table you do not need to
-	use this function. When omitted, CodeIgniter assumes you wish to SELECT *
-
-$this->db->select() accepts an optional second parameter. If you set it
-to FALSE, CodeIgniter will not try to protect your field or table names
-with backticks. This is useful if you need a compound select statement.
-
-::
-
-	$this->db->select('(SELECT SUM(payments.amount) FROM payments WHERE payments.invoice_id=4') AS amount_paid', FALSE);
-	$query = $this->db->get('mytable');
-
-
-$this->db->select_max()
-=======================
-
-Writes a "SELECT MAX(field)" portion for your query. You can optionally
-include a second parameter to rename the resulting field.
-
-::
-
-	$this->db->select_max('age');
-	$query = $this->db->get('members');  // Produces: SELECT MAX(age) as age FROM members
-
-	$this->db->select_max('age', 'member_age');
-	$query = $this->db->get('members'); // Produces: SELECT MAX(age) as member_age FROM members
-
-
-$this->db->select_min()
-=======================
-
-Writes a "SELECT MIN(field)" portion for your query. As with
-select_max(), You can optionally include a second parameter to rename
-the resulting field.
-
-::
-
-	$this->db->select_min('age');
-	$query = $this->db->get('members'); // Produces: SELECT MIN(age) as age FROM members
-
-
-$this->db->select_avg()
-=======================
-
-Writes a "SELECT AVG(field)" portion for your query. As with
-select_max(), You can optionally include a second parameter to rename
-the resulting field.
-
-::
-
-	$this->db->select_avg('age');
-	$query = $this->db->get('members'); // Produces: SELECT AVG(age) as age FROM members
-
-
-$this->db->select_sum()
-=======================
-
-Writes a "SELECT SUM(field)" portion for your query. As with
-select_max(), You can optionally include a second parameter to rename
-the resulting field.
-
-::
-
-	$this->db->select_sum('age');
-	$query = $this->db->get('members'); // Produces: SELECT SUM(age) as age FROM members
-
-
-$this->db->from()
-=================
-
-Permits you to write the FROM portion of your query::
-
-	$this->db->select('title, content, date');
-	$this->db->from('mytable');
-	$query = $this->db->get();  // Produces: SELECT title, content, date FROM mytable
-
-.. note:: As shown earlier, the FROM portion of your query can be specified
-	in the $this->db->get() function, so use whichever method you prefer.
-
-$this->db->join()
-=================
-
-Permits you to write the JOIN portion of your query::
-
-	$this->db->select('*');
-	$this->db->from('blogs');
-	$this->db->join('comments', 'comments.id = blogs.id');
-	$query = $this->db->get();
-
-	// Produces:
-	// SELECT * FROM blogs JOIN comments ON comments.id = blogs.id
-
-Multiple function calls can be made if you need several joins in one
-query.
-
-If you need a specific type of JOIN you can specify it via the third
-parameter of the function. Options are: left, right, outer, inner, left
-outer, and right outer.
-
-::
-
-	$this->db->join('comments', 'comments.id = blogs.id', 'left');
-	// Produces: LEFT JOIN comments ON comments.id = blogs.id
-
-$this->db->where()
-==================
-
-This function enables you to set **WHERE** clauses using one of four
-methods:
-
-.. note:: All values passed to this function are escaped automatically,
-	producing safer queries.
-
-#. **Simple key/value method:**
-
-	::
-
-		$this->db->where('name', $name); // Produces: WHERE name = 'Joe'
-
-	Notice that the equal sign is added for you.
-
-	If you use multiple function calls they will be chained together with
-	AND between them:
-
-	::
-
-		$this->db->where('name', $name);
-		$this->db->where('title', $title);
-		$this->db->where('status', $status);
-		// WHERE name = 'Joe' AND title = 'boss' AND status = 'active'
-
-#. **Custom key/value method:**
-	You can include an operator in the first parameter in order to
-	control the comparison:
-
-	::
-
-		$this->db->where('name !=', $name);
-		$this->db->where('id <', $id); // Produces: WHERE name != 'Joe' AND id < 45
-
-#. **Associative array method:**
-
-	::
-
-		$array = array('name' => $name, 'title' => $title, 'status' => $status);
-		$this->db->where($array);
-		// Produces: WHERE name = 'Joe' AND title = 'boss' AND status = 'active'
-
-	You can include your own operators using this method as well:
-
-	::
-
-		$array = array('name !=' => $name, 'id <' => $id, 'date >' => $date);
-		$this->db->where($array);
-
-#. **Custom string:**
-	You can write your own clauses manually::
-
-		$where = "name='Joe' AND status='boss' OR status='active'";
-		$this->db->where($where);
-
-
-$this->db->where() accepts an optional third parameter. If you set it to
-FALSE, CodeIgniter will not try to protect your field or table names
-with backticks.
-
-::
-
-	$this->db->where('MATCH (field) AGAINST ("value")', NULL, FALSE);
-
-
-$this->db->or_where()
-=====================
-
-This function is identical to the one above, except that multiple
-instances are joined by OR::
-
-	$this->db->where('name !=', $name);
-	$this->db->or_where('id >', $id);  // Produces: WHERE name != 'Joe' OR id > 50
-
-.. note:: or_where() was formerly known as orwhere(), which has been
-	removed.
-
-$this->db->where_in()
-=====================
-
-Generates a WHERE field IN ('item', 'item') SQL query joined with AND if
-appropriate
-
-::
-
-	$names = array('Frank', 'Todd', 'James');
-	$this->db->where_in('username', $names);
-	// Produces: WHERE username IN ('Frank', 'Todd', 'James')
-
-
-$this->db->or_where_in()
-========================
-
-Generates a WHERE field IN ('item', 'item') SQL query joined with OR if
-appropriate
-
-::
-
-	$names = array('Frank', 'Todd', 'James');
-	$this->db->or_where_in('username', $names);
-	// Produces: OR username IN ('Frank', 'Todd', 'James')
-
-
-$this->db->where_not_in()
-=========================
-
-Generates a WHERE field NOT IN ('item', 'item') SQL query joined with
-AND if appropriate
-
-::
-
-	$names = array('Frank', 'Todd', 'James');
-	$this->db->where_not_in('username', $names);
-	// Produces: WHERE username NOT IN ('Frank', 'Todd', 'James')
-
-
-$this->db->or_where_not_in()
-============================
-
-Generates a WHERE field NOT IN ('item', 'item') SQL query joined with OR
-if appropriate
-
-::
-
-	$names = array('Frank', 'Todd', 'James');
-	$this->db->or_where_not_in('username', $names);
-	// Produces: OR username NOT IN ('Frank', 'Todd', 'James')
-
-
-$this->db->like()
-=================
-
-This function enables you to generate **LIKE** clauses, useful for doing
-searches.
-
-.. note:: All values passed to this function are escaped automatically.
-
-#. **Simple key/value method:**
-
-	::
-
-		$this->db->like('title', 'match');     // Produces: WHERE title LIKE '%match%'
-
-	If you use multiple function calls they will be chained together with
-	AND between them::
-
-		$this->db->like('title', 'match');
-		$this->db->like('body', 'match');
-		// WHERE title LIKE '%match%' AND  body LIKE '%match%
-
-	If you want to control where the wildcard (%) is placed, you can use
-	an optional third argument. Your options are 'before', 'after' and
-	'both' (which is the default).
-
-	::
-
-		$this->db->like('title', 'match', 'before');	// Produces: WHERE title LIKE '%match'
-		$this->db->like('title', 'match', 'after');		// Produces: WHERE title LIKE 'match%'
-		$this->db->like('title', 'match', 'both');		// Produces: WHERE title LIKE '%match%'
-
-#. **Associative array method:**
-
-	::
-
-		$array = array('title' => $match, 'page1' => $match, 'page2' => $match);
-		$this->db->like($array);
-		// WHERE title LIKE '%match%' AND  page1 LIKE '%match%' AND  page2 LIKE '%match%'
-
-
-$this->db->or_like()
-====================
-
-This function is identical to the one above, except that multiple
-instances are joined by OR::
-
-	$this->db->like('title', 'match'); $this->db->or_like('body', $match);
-	// WHERE title LIKE '%match%' OR  body LIKE '%match%'
-
-.. note:: or_like() was formerly known as orlike(), which has been removed.
-
-$this->db->not_like()
-=====================
-
-This function is identical to **like()**, except that it generates NOT
-LIKE statements::
-
-	$this->db->not_like('title', 'match');  // WHERE title NOT LIKE '%match%
-
-$this->db->or_not_like()
-========================
-
-This function is identical to **not_like()**, except that multiple
-instances are joined by OR::
-
-	$this->db->like('title', 'match');
-	$this->db->or_not_like('body', 'match');
-	// WHERE title  LIKE '%match% OR body NOT LIKE '%match%'
-
-$this->db->group_by()
-=====================
-
-Permits you to write the GROUP BY portion of your query::
-
-	$this->db->group_by("title"); // Produces: GROUP BY title
-
-You can also pass an array of multiple values as well::
-
-	$this->db->group_by(array("title", "date"));  // Produces: GROUP BY title, date
-
-.. note:: group_by() was formerly known as groupby(), which has been
-	removed.
-
-$this->db->distinct()
-=====================
-
-Adds the "DISTINCT" keyword to a query
-
-::
-
-	$this->db->distinct();
-	$this->db->get('table'); // Produces: SELECT DISTINCT * FROM table
-
-
-$this->db->having()
-===================
-
-Permits you to write the HAVING portion of your query. There are 2
-possible syntaxes, 1 argument or 2::
-
-	$this->db->having('user_id = 45');  // Produces: HAVING user_id = 45
-	$this->db->having('user_id',  45);  // Produces: HAVING user_id = 45
-
-You can also pass an array of multiple values as well::
-
-	$this->db->having(array('title =' => 'My Title', 'id <' => $id));
-	// Produces: HAVING title = 'My Title', id < 45
-
-
-If you are using a database that CodeIgniter escapes queries for, you
-can prevent escaping content by passing an optional third argument, and
-setting it to FALSE.
-
-::
-
-	$this->db->having('user_id',  45);  // Produces: HAVING `user_id` = 45 in some databases such as MySQL
-	$this->db->having('user_id',  45, FALSE);  // Produces: HAVING user_id = 45
-
-
-$this->db->or_having()
-======================
-
-Identical to having(), only separates multiple clauses with "OR".
-
-$this->db->order_by()
-=====================
-
-Lets you set an ORDER BY clause. The first parameter contains the name
-of the column you would like to order by. The second parameter lets you
-set the direction of the result. Options are asc or desc, or random.
-
-::
-
-	$this->db->order_by("title", "desc");  // Produces: ORDER BY title DESC
-
-You can also pass your own string in the first parameter::
-
-	$this->db->order_by('title desc, name asc');  // Produces: ORDER BY title DESC, name ASC
-
-Or multiple function calls can be made if you need multiple fields.
-
-::
-
-	$this->db->order_by("title", "desc");
-	$this->db->order_by("name", "asc"); // Produces: ORDER BY title DESC, name ASC
-
-
-.. note:: order_by() was formerly known as orderby(), which has been
-	removed.
-
-.. note:: random ordering is not currently supported in Oracle or MSSQL
-	drivers. These will default to 'ASC'.
-
-$this->db->limit()
-==================
-
-Lets you limit the number of rows you would like returned by the query::
-
-	$this->db->limit(10);  // Produces: LIMIT 10
-
-The second parameter lets you set a result offset.
-
-::
-
-	$this->db->limit(10, 20);  // Produces: LIMIT 20, 10 (in MySQL.  Other databases have slightly different syntax)
-
-$this->db->count_all_results()
-==============================
-
-Permits you to determine the number of rows in a particular Active
-Record query. Queries will accept Active Record restrictors such as
-where(), or_where(), like(), or_like(), etc. Example::
-
-	echo $this->db->count_all_results('my_table');  // Produces an integer, like 25
-	$this->db->like('title', 'match');
-	$this->db->from('my_table');
-	echo $this->db->count_all_results(); // Produces an integer, like 17
-
-$this->db->count_all()
-======================
-
-Permits you to determine the number of rows in a particular table.
-Submit the table name in the first parameter. Example::
-
-	echo $this->db->count_all('my_table');  // Produces an integer, like 25
-
-**************
-Query grouping
-**************
-
-Query grouping allows you to create groups of WHERE clauses by enclosing them in parentheses. This will allow
-you to create queries with complex WHERE clauses. Nested groups are supported. Example:
-
-	$this->db->select('*')->from('my_table')
-		->group_start()
-			->where('a', 'a')
-			->or_group_start()
-				->where('b', 'b')
-				->where('c', 'c')
-			->group_end()
-		->group_end()
-		->where('d', 'd')
-	->get();
-
-	// Generates:
-	// SELECT * FROM (`my_table`) WHERE ( `a` = 'a' OR ( `b` = 'b' AND `c` = 'c' ) ) AND `d` = 'd'
-
-.. note:: groups need to be balanced, make sure every group_start() is matched by a group_end().
-
-$this->db->group_start()
-========================
-
-Starts a new group by adding an opening parenthesis to the WHERE clause of the query.
-
-$this->db->or_group_start()
-===========================
-
-Starts a new group by adding an opening parenthesis to the WHERE clause of the query, prefixing it with 'OR'.
-
-$this->db->not_group_start()
-============================
-
-Starts a new group by adding an opening parenthesis to the WHERE clause of the query, prefixing it with 'NOT'.
-
-$this->db->or_not_group_start()
-===============================
-
-Starts a new group by adding an opening parenthesis to the WHERE clause of the query, prefixing it with 'OR NOT'.
-
-$this->db->group_end()
-======================
-
-Ends the current group by adding an closing parenthesis to the WHERE clause of the query.
-
-**************
-Inserting Data
-**************
-
-$this->db->insert()
-===================
-
-Generates an insert string based on the data you supply, and runs the
-query. You can either pass an **array** or an **object** to the
-function. Here is an example using an array::
-
-	$data = array(
-		'title' => 'My title',
-		'name' => 'My Name',
-		'date' => 'My date'
-	);
-
-	$this->db->insert('mytable', $data);
-	// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
-
-The first parameter will contain the table name, the second is an
-associative array of values.
-
-Here is an example using an object::
-
-	/*
-	class Myclass {
-		var  $title = 'My Title';
-		var  $content = 'My Content';
-		var  $date = 'My Date';
-	}
-	*/
-
-	$object = new Myclass;
-	$this->db->insert('mytable', $object);
-	// Produces: INSERT INTO mytable (title, content, date) VALUES ('My Title', 'My Content', 'My Date')
-
-The first parameter will contain the table name, the second is an
-object.
-
-.. note:: All values are escaped automatically producing safer queries.
-
-$this->db->get_compiled_insert()
-================================
-Compiles the insertion query just like `$this->db->insert()`_ but does not
-*run* the query. This method simply returns the SQL query as a string.
-
-Example::
-
-	$data = array(
-		'title' => 'My title',
-		'name'  => 'My Name',
-		'date'  => 'My date'
-	);
-
-	$sql = $this->db->set($data)->get_compiled_insert('mytable');
-	echo $sql;
-
-	// Produces string: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
-
-The second parameter enables you to set whether or not the active record query
-will be reset (by default it will be--just like `$this->db->insert()`_)::
-
-	echo $this->db->set('title', 'My Title')->get_compiled_insert('mytable', FALSE);
-
-	// Produces string: INSERT INTO mytable (title) VALUES ('My Title')
-
-	echo $this->db->set('content', 'My Content')->get_compiled_insert();
-
-	// Produces string: INSERT INTO mytable (title, content) VALUES ('My Title', 'My Content')
-
-The key thing to notice in the above example is that the second query did not
-utlize `$this->db->from()`_ nor did it pass a table name into the first
-parameter. The reason this worked is because the query has not been executed
-using `$this->db->insert()`_ which resets values or reset directly using
-`$this->db->reset_query()`_.
-
-$this->db->insert_batch()
-=========================
-
-Generates an insert string based on the data you supply, and runs the
-query. You can either pass an **array** or an **object** to the
-function. Here is an example using an array::
-
-	$data = array(
-		array(
-			'title' => 'My title',
-			'name' => 'My Name',
-			'date' => 'My date'
-		),
-		array(
-			'title' => 'Another title',
-			'name' => 'Another Name',
-			'date' => 'Another date'
-		)
-	);
-
-	$this->db->insert_batch('mytable', $data);
-	// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'),  ('Another title', 'Another name', 'Another date')
-
-The first parameter will contain the table name, the second is an
-associative array of values.
-
-.. note:: All values are escaped automatically producing safer queries.
-
-$this->db->set()
-================
-
-This function enables you to set values for inserts or updates.
-
-**It can be used instead of passing a data array directly to the insert
-or update functions:**
-
-::
-
-	$this->db->set('name', $name);
-	$this->db->insert('mytable');  // Produces: INSERT INTO mytable (name) VALUES ('{$name}')
-
-If you use multiple function called they will be assembled properly
-based on whether you are doing an insert or an update::
-
-	$this->db->set('name', $name);
-	$this->db->set('title', $title);
-	$this->db->set('status', $status);
-	$this->db->insert('mytable');
-
-**set()** will also accept an optional third parameter ($escape), that
-will prevent data from being escaped if set to FALSE. To illustrate the
-difference, here is set() used both with and without the escape
-parameter.
-
-::
-
-	$this->db->set('field', 'field+1', FALSE);
-	$this->db->insert('mytable'); // gives INSERT INTO mytable (field) VALUES (field+1)
-	$this->db->set('field', 'field+1');
-	$this->db->insert('mytable'); // gives INSERT INTO mytable (field) VALUES ('field+1')
-
-
-You can also pass an associative array to this function::
-
-	$array = array(
-		'name' => $name,
-		'title' => $title,
-		'status' => $status
-	);
-
-	$this->db->set($array);
-	$this->db->insert('mytable');
-
-Or an object::
-
-	/*
-	class Myclass {
-		var  $title = 'My Title';
-		var  $content = 'My Content';
-		var  $date = 'My Date';
-	}
-	*/
-
-	$object = new Myclass;
-	$this->db->set($object);
-	$this->db->insert('mytable');
-
-
-*************
-Updating Data
-*************
-
-$this->db->update()
-===================
-
-Generates an update string and runs the query based on the data you
-supply. You can pass an **array** or an **object** to the function. Here
-is an example using an array::
-
-	$data = array(
-		'title' => $title,
-		'name' => $name,
-		'date' => $date
-	);
-
-	$this->db->where('id', $id);
-	$this->db->update('mytable', $data);
-	// Produces: // UPDATE mytable  // SET title = '{$title}', name = '{$name}', date = '{$date}' // WHERE id = $id
-
-Or you can supply an object::
-
-	/*
-	class Myclass {
-		var  $title = 'My Title';
-		var  $content = 'My Content';
-		var  $date = 'My Date';
-	}
-	*/
-
-	$object = new Myclass;
-	$this->db->where('id', $id);
-	$this->db->update('mytable', $object);
-	// Produces: // UPDATE mytable  // SET title = '{$title}', name = '{$name}', date = '{$date}' // WHERE id = $id
-
-.. note:: All values are escaped automatically producing safer queries.
-
-You'll notice the use of the $this->db->where() function, enabling you
-to set the WHERE clause. You can optionally pass this information
-directly into the update function as a string::
-
-	$this->db->update('mytable', $data, "id = 4");
-
-Or as an array::
-
-	$this->db->update('mytable', $data, array('id' => $id));
-
-You may also use the $this->db->set() function described above when
-performing updates.
-
-$this->db->update_batch()
-=========================
-
-Generates an update string based on the data you supply, and runs the query.
-You can either pass an **array** or an **object** to the function.
-Here is an example using an array::
-
-	$data = array(
-	   array(
-	      'title' => 'My title' ,
-	      'name' => 'My Name 2' ,
-	      'date' => 'My date 2'
-	   ),
-	   array(
-	      'title' => 'Another title' ,
-	      'name' => 'Another Name 2' ,
-	      'date' => 'Another date 2'
-	   )
-	);
-
-	$this->db->update_batch('mytable', $data, 'title');
-
-	// Produces:
-	// UPDATE `mytable` SET `name` = CASE
-	// WHEN `title` = 'My title' THEN 'My Name 2'
-	// WHEN `title` = 'Another title' THEN 'Another Name 2'
-	// ELSE `name` END,
-	// `date` = CASE
-	// WHEN `title` = 'My title' THEN 'My date 2'
-	// WHEN `title` = 'Another title' THEN 'Another date 2'
-	// ELSE `date` END
-	// WHERE `title` IN ('My title','Another title')
-
-The first parameter will contain the table name, the second is an associative
-array of values, the third parameter is the where key.
-
-.. note:: All values are escaped automatically producing safer queries.
-
-$this->db->get_compiled_update()
-================================
-
-This works exactly the same way as ``$this->db->get_compiled_insert()`` except
-that it produces an UPDATE SQL string instead of an INSERT SQL string.
-
-For more information view documentation for `$this->db->get_compiled_insert()`_.
-
-
-*************
-Deleting Data
-*************
-
-$this->db->delete()
-===================
-
-Generates a delete SQL string and runs the query.
-
-::
-
-	$this->db->delete('mytable', array('id' => $id));  // Produces: // DELETE FROM mytable  // WHERE id = $id
-
-The first parameter is the table name, the second is the where clause.
-You can also use the where() or or_where() functions instead of passing
-the data to the second parameter of the function::
-
-	$this->db->where('id', $id);
-	$this->db->delete('mytable');
-
-	// Produces:
-	// DELETE FROM mytable
-	// WHERE id = $id
-
-
-An array of table names can be passed into delete() if you would like to
-delete data from more than 1 table.
-
-::
-
-	$tables = array('table1', 'table2', 'table3');
-	$this->db->where('id', '5');
-	$this->db->delete($tables);
-
-
-If you want to delete all data from a table, you can use the truncate()
-function, or empty_table().
-
-$this->db->empty_table()
-========================
-
-Generates a delete SQL string and runs the
-query.::
-
-	  $this->db->empty_table('mytable'); // Produces: DELETE FROM mytable
-
-
-$this->db->truncate()
-=====================
-
-Generates a truncate SQL string and runs the query.
-
-::
-
-	$this->db->from('mytable');
-	$this->db->truncate();
-
-	// or
-
-	$this->db->truncate('mytable');
-
-	// Produce:
-	// TRUNCATE mytable
-
-.. note:: If the TRUNCATE command isn't available, truncate() will
-	execute as "DELETE FROM table".
-
-$this->db->get_compiled_delete()
-================================
-This works exactly the same way as ``$this->db->get_compiled_insert()`` except
-that it produces a DELETE SQL string instead of an INSERT SQL string.
-
-For more information view documentation for `$this->db->get_compiled_insert()`_.
-
-***************
-Method Chaining
-***************
-
-Method chaining allows you to simplify your syntax by connecting
-multiple functions. Consider this example::
-
-	$query = $this->db->select('title')
-				->where('id', $id)
-				->limit(10, 20)
-				->get('mytable');
-
-.. _ar-caching:
-
-*********************
-Active Record Caching
-*********************
-
-While not "true" caching, Active Record enables you to save (or "cache")
-certain parts of your queries for reuse at a later point in your
-script's execution. Normally, when an Active Record call is completed,
-all stored information is reset for the next call. With caching, you can
-prevent this reset, and reuse information easily.
-
-Cached calls are cumulative. If you make 2 cached select() calls, and
-then 2 uncached select() calls, this will result in 4 select() calls.
-There are three Caching functions available:
-
-$this->db->start_cache()
-========================
-
-This function must be called to begin caching. All Active Record queries
-of the correct type (see below for supported queries) are stored for
-later use.
-
-$this->db->stop_cache()
-=======================
-
-This function can be called to stop caching.
-
-$this->db->flush_cache()
-========================
-
-This function deletes all items from the Active Record cache.
-
-Here's a usage example::
-
-	$this->db->start_cache();
-	$this->db->select('field1');
-	$this->db->stop_cache();
-	$this->db->get('tablename');
-	//Generates: SELECT `field1` FROM (`tablename`)
-
-	$this->db->select('field2');
-	$this->db->get('tablename');
-	//Generates:  SELECT `field1`, `field2` FROM (`tablename`)
-
-	$this->db->flush_cache();
-	$this->db->select('field2');
-	$this->db->get('tablename');
-	//Generates:  SELECT `field2` FROM (`tablename`)
-
-
-.. note:: The following statements can be cached: select, from, join,
-	where, like, group_by, having, order_by, set
-
-
-$this->db->reset_query()
-========================
-
-Resetting Active Record allows you to start fresh with your query without
-executing it first using a method like $this->db->get() or $this->db->insert().
-Just like the methods that execute a query, this will *not* reset items you've
-cached using `Active Record Caching`_.
-
-This is useful in situations where you are using Active Record to generate SQL
-(ex. ``$this->db->get_compiled_select()``) but then choose to, for instance,
-run the query::
-
-	// Note that the second parameter of the get_compiled_select method is FALSE
-	$sql = $this->db->select(array('field1','field2'))
-					->where('field3',5)
-					->get_compiled_select('mytable', FALSE);
-
-	// ...
-	// Do something crazy with the SQL code... like add it to a cron script for
-	// later execution or something...
-	// ...
-
-	$data = $this->db->get()->result_array();
-
-	// Would execute and return an array of results of the following query:
-	// SELECT field1, field1 from mytable where field3 = 5;

+###################
+Query Builder Class
+###################
+
+CodeIgniter gives you access to a Query Builder class. This pattern 
+allows information to be retrieved, inserted, and updated in your 
+database with minimal scripting. In some cases only one or two lines
+of code are necessary to perform a database action.
+CodeIgniter does not require that each database table be its own class
+file. It instead provides a more simplified interface.
+
+Beyond simplicity, a major benefit to using the Query Builder features
+is that it allows you to create database independent applications, since
+the query syntax is generated by each database adapter. It also allows
+for safer queries, since the values are escaped automatically by the
+system.
+
+.. note:: If you intend to write your own queries you can disable this
+	class in your database config file, allowing the core database library
+	and adapter to utilize fewer resources.
+
+.. contents:: Page Contents
+
+**************
+Selecting Data
+**************
+
+The following functions allow you to build SQL **SELECT** statements.
+
+$this->db->get()
+================
+
+Runs the selection query and returns the result. Can be used by itself
+to retrieve all records from a table::
+
+	$query = $this->db->get('mytable');  // Produces: SELECT * FROM mytable
+
+The second and third parameters enable you to set a limit and offset
+clause::
+
+	$query = $this->db->get('mytable', 10, 20);
+	// Produces: SELECT * FROM mytable LIMIT 20, 10 (in MySQL. Other databases have slightly different syntax)
+
+You'll notice that the above function is assigned to a variable named
+$query, which can be used to show the results::
+
+	$query = $this->db->get('mytable');
+
+	foreach ($query->result() as $row)
+	{
+		echo $row->title;
+	}
+
+Please visit the :doc:`result functions <results>` page for a full
+discussion regarding result generation.
+
+$this->db->get_compiled_select()
+================================
+
+Compiles the selection query just like `$this->db->get()`_ but does not *run*
+the query. This method simply returns the SQL query as a string.
+
+Example::
+
+	$sql = $this->db->get_compiled_select('mytable');
+	echo $sql;
+
+	// Produces string: SELECT * FROM mytable
+
+The second parameter enables you to set whether or not the query builder query
+will be reset (by default it will be&mdash;just like `$this->db->get()`)::
+
+	echo $this->db->limit(10,20)->get_compiled_select('mytable', FALSE);
+	// Produces string: SELECT * FROM mytable LIMIT 20, 10
+	// (in MySQL. Other databases have slightly different syntax)
+
+	echo $this->db->select('title, content, date')->get_compiled_select();
+
+	// Produces string: SELECT title, content, date FROM mytable
+
+The key thing to notice in the above example is that the second query did not
+utilize `$this->db->from()`_ and did not pass a table name into the first
+parameter. The reason for this outcome is because the query has not been
+executed using `$this->db->get()`_ which resets values or reset directly
+using `$this->db->reset_query()`_.
+
+
+$this->db->get_where()
+======================
+
+Identical to the above function except that it permits you to add a
+"where" clause in the second parameter, instead of using the db->where()
+function::
+
+	$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);
+
+Please read the about the where function below for more information.
+
+.. note:: get_where() was formerly known as getwhere(), which has been removed
+
+$this->db->select()
+===================
+
+Permits you to write the SELECT portion of your query::
+
+	$this->db->select('title, content, date');
+	$query = $this->db->get('mytable');  // Produces: SELECT title, content, date FROM mytable
+
+
+.. note:: If you are selecting all (\*) from a table you do not need to
+	use this function. When omitted, CodeIgniter assumes you wish to SELECT *
+
+$this->db->select() accepts an optional second parameter. If you set it
+to FALSE, CodeIgniter will not try to protect your field or table names
+with backticks. This is useful if you need a compound select statement.
+
+::
+
+	$this->db->select('(SELECT SUM(payments.amount) FROM payments WHERE payments.invoice_id=4') AS amount_paid', FALSE);
+	$query = $this->db->get('mytable');
+
+
+$this->db->select_max()
+=======================
+
+Writes a "SELECT MAX(field)" portion for your query. You can optionally
+include a second parameter to rename the resulting field.
+
+::
+
+	$this->db->select_max('age');
+	$query = $this->db->get('members');  // Produces: SELECT MAX(age) as age FROM members
+
+	$this->db->select_max('age', 'member_age');
+	$query = $this->db->get('members'); // Produces: SELECT MAX(age) as member_age FROM members
+
+
+$this->db->select_min()
+=======================
+
+Writes a "SELECT MIN(field)" portion for your query. As with
+select_max(), You can optionally include a second parameter to rename
+the resulting field.
+
+::
+
+	$this->db->select_min('age');
+	$query = $this->db->get('members'); // Produces: SELECT MIN(age) as age FROM members
+
+
+$this->db->select_avg()
+=======================
+
+Writes a "SELECT AVG(field)" portion for your query. As with
+select_max(), You can optionally include a second parameter to rename
+the resulting field.
+
+::
+
+	$this->db->select_avg('age');
+	$query = $this->db->get('members'); // Produces: SELECT AVG(age) as age FROM members
+
+
+$this->db->select_sum()
+=======================
+
+Writes a "SELECT SUM(field)" portion for your query. As with
+select_max(), You can optionally include a second parameter to rename
+the resulting field.
+
+::
+
+	$this->db->select_sum('age');
+	$query = $this->db->get('members'); // Produces: SELECT SUM(age) as age FROM members
+
+
+$this->db->from()
+=================
+
+Permits you to write the FROM portion of your query::
+
+	$this->db->select('title, content, date');
+	$this->db->from('mytable');
+	$query = $this->db->get();  // Produces: SELECT title, content, date FROM mytable
+
+.. note:: As shown earlier, the FROM portion of your query can be specified
+	in the $this->db->get() function, so use whichever method you prefer.
+
+$this->db->join()
+=================
+
+Permits you to write the JOIN portion of your query::
+
+	$this->db->select('*');
+	$this->db->from('blogs');
+	$this->db->join('comments', 'comments.id = blogs.id');
+	$query = $this->db->get();
+
+	// Produces:
+	// SELECT * FROM blogs JOIN comments ON comments.id = blogs.id
+
+Multiple function calls can be made if you need several joins in one
+query.
+
+If you need a specific type of JOIN you can specify it via the third
+parameter of the function. Options are: left, right, outer, inner, left
+outer, and right outer.
+
+::
+
+	$this->db->join('comments', 'comments.id = blogs.id', 'left');
+	// Produces: LEFT JOIN comments ON comments.id = blogs.id
+
+$this->db->where()
+==================
+
+This function enables you to set **WHERE** clauses using one of four
+methods:
+
+.. note:: All values passed to this function are escaped automatically,
+	producing safer queries.
+
+#. **Simple key/value method:**
+
+	::
+
+		$this->db->where('name', $name); // Produces: WHERE name = 'Joe'
+
+	Notice that the equal sign is added for you.
+
+	If you use multiple function calls they will be chained together with
+	AND between them:
+
+	::
+
+		$this->db->where('name', $name);
+		$this->db->where('title', $title);
+		$this->db->where('status', $status);
+		// WHERE name = 'Joe' AND title = 'boss' AND status = 'active'
+
+#. **Custom key/value method:**
+	You can include an operator in the first parameter in order to
+	control the comparison:
+
+	::
+
+		$this->db->where('name !=', $name);
+		$this->db->where('id <', $id); // Produces: WHERE name != 'Joe' AND id < 45
+
+#. **Associative array method:**
+
+	::
+
+		$array = array('name' => $name, 'title' => $title, 'status' => $status);
+		$this->db->where($array);
+		// Produces: WHERE name = 'Joe' AND title = 'boss' AND status = 'active'
+
+	You can include your own operators using this method as well:
+
+	::
+
+		$array = array('name !=' => $name, 'id <' => $id, 'date >' => $date);
+		$this->db->where($array);
+
+#. **Custom string:**
+	You can write your own clauses manually::
+
+		$where = "name='Joe' AND status='boss' OR status='active'";
+		$this->db->where($where);
+
+
+$this->db->where() accepts an optional third parameter. If you set it to
+FALSE, CodeIgniter will not try to protect your field or table names
+with backticks.
+
+::
+
+	$this->db->where('MATCH (field) AGAINST ("value")', NULL, FALSE);
+
+
+$this->db->or_where()
+=====================
+
+This function is identical to the one above, except that multiple
+instances are joined by OR::
+
+	$this->db->where('name !=', $name);
+	$this->db->or_where('id >', $id);  // Produces: WHERE name != 'Joe' OR id > 50
+
+.. note:: or_where() was formerly known as orwhere(), which has been
+	removed.
+
+$this->db->where_in()
+=====================
+
+Generates a WHERE field IN ('item', 'item') SQL query joined with AND if
+appropriate
+
+::
+
+	$names = array('Frank', 'Todd', 'James');
+	$this->db->where_in('username', $names);
+	// Produces: WHERE username IN ('Frank', 'Todd', 'James')
+
+
+$this->db->or_where_in()
+========================
+
+Generates a WHERE field IN ('item', 'item') SQL query joined with OR if
+appropriate
+
+::
+
+	$names = array('Frank', 'Todd', 'James');
+	$this->db->or_where_in('username', $names);
+	// Produces: OR username IN ('Frank', 'Todd', 'James')
+
+
+$this->db->where_not_in()
+=========================
+
+Generates a WHERE field NOT IN ('item', 'item') SQL query joined with
+AND if appropriate
+
+::
+
+	$names = array('Frank', 'Todd', 'James');
+	$this->db->where_not_in('username', $names);
+	// Produces: WHERE username NOT IN ('Frank', 'Todd', 'James')
+
+
+$this->db->or_where_not_in()
+============================
+
+Generates a WHERE field NOT IN ('item', 'item') SQL query joined with OR
+if appropriate
+
+::
+
+	$names = array('Frank', 'Todd', 'James');
+	$this->db->or_where_not_in('username', $names);
+	// Produces: OR username NOT IN ('Frank', 'Todd', 'James')
+
+
+$this->db->like()
+=================
+
+This function enables you to generate **LIKE** clauses, useful for doing
+searches.
+
+.. note:: All values passed to this function are escaped automatically.
+
+#. **Simple key/value method:**
+
+	::
+
+		$this->db->like('title', 'match');     // Produces: WHERE title LIKE '%match%'
+
+	If you use multiple function calls they will be chained together with
+	AND between them::
+
+		$this->db->like('title', 'match');
+		$this->db->like('body', 'match');
+		// WHERE title LIKE '%match%' AND  body LIKE '%match%
+
+	If you want to control where the wildcard (%) is placed, you can use
+	an optional third argument. Your options are 'before', 'after' and
+	'both' (which is the default).
+
+	::
+
+		$this->db->like('title', 'match', 'before');	// Produces: WHERE title LIKE '%match'
+		$this->db->like('title', 'match', 'after');		// Produces: WHERE title LIKE 'match%'
+		$this->db->like('title', 'match', 'both');		// Produces: WHERE title LIKE '%match%'
+
+#. **Associative array method:**
+
+	::
+
+		$array = array('title' => $match, 'page1' => $match, 'page2' => $match);
+		$this->db->like($array);
+		// WHERE title LIKE '%match%' AND  page1 LIKE '%match%' AND  page2 LIKE '%match%'
+
+
+$this->db->or_like()
+====================
+
+This function is identical to the one above, except that multiple
+instances are joined by OR::
+
+	$this->db->like('title', 'match'); $this->db->or_like('body', $match);
+	// WHERE title LIKE '%match%' OR  body LIKE '%match%'
+
+.. note:: or_like() was formerly known as orlike(), which has been removed.
+
+$this->db->not_like()
+=====================
+
+This function is identical to **like()**, except that it generates NOT
+LIKE statements::
+
+	$this->db->not_like('title', 'match');  // WHERE title NOT LIKE '%match%
+
+$this->db->or_not_like()
+========================
+
+This function is identical to **not_like()**, except that multiple
+instances are joined by OR::
+
+	$this->db->like('title', 'match');
+	$this->db->or_not_like('body', 'match');
+	// WHERE title  LIKE '%match% OR body NOT LIKE '%match%'
+
+$this->db->group_by()
+=====================
+
+Permits you to write the GROUP BY portion of your query::
+
+	$this->db->group_by("title"); // Produces: GROUP BY title
+
+You can also pass an array of multiple values as well::
+
+	$this->db->group_by(array("title", "date"));  // Produces: GROUP BY title, date
+
+.. note:: group_by() was formerly known as groupby(), which has been
+	removed.
+
+$this->db->distinct()
+=====================
+
+Adds the "DISTINCT" keyword to a query
+
+::
+
+	$this->db->distinct();
+	$this->db->get('table'); // Produces: SELECT DISTINCT * FROM table
+
+
+$this->db->having()
+===================
+
+Permits you to write the HAVING portion of your query. There are 2
+possible syntaxes, 1 argument or 2::
+
+	$this->db->having('user_id = 45');  // Produces: HAVING user_id = 45
+	$this->db->having('user_id',  45);  // Produces: HAVING user_id = 45
+
+You can also pass an array of multiple values as well::
+
+	$this->db->having(array('title =' => 'My Title', 'id <' => $id));
+	// Produces: HAVING title = 'My Title', id < 45
+
+
+If you are using a database that CodeIgniter escapes queries for, you
+can prevent escaping content by passing an optional third argument, and
+setting it to FALSE.
+
+::
+
+	$this->db->having('user_id',  45);  // Produces: HAVING `user_id` = 45 in some databases such as MySQL
+	$this->db->having('user_id',  45, FALSE);  // Produces: HAVING user_id = 45
+
+
+$this->db->or_having()
+======================
+
+Identical to having(), only separates multiple clauses with "OR".
+
+$this->db->order_by()
+=====================
+
+Lets you set an ORDER BY clause. The first parameter contains the name
+of the column you would like to order by. The second parameter lets you
+set the direction of the result. Options are asc or desc, or random.
+
+::
+
+	$this->db->order_by("title", "desc");  // Produces: ORDER BY title DESC
+
+You can also pass your own string in the first parameter::
+
+	$this->db->order_by('title desc, name asc');  // Produces: ORDER BY title DESC, name ASC
+
+Or multiple function calls can be made if you need multiple fields.
+
+::
+
+	$this->db->order_by("title", "desc");
+	$this->db->order_by("name", "asc"); // Produces: ORDER BY title DESC, name ASC
+
+
+.. note:: order_by() was formerly known as orderby(), which has been
+	removed.
+
+.. note:: random ordering is not currently supported in Oracle or MSSQL
+	drivers. These will default to 'ASC'.
+
+$this->db->limit()
+==================
+
+Lets you limit the number of rows you would like returned by the query::
+
+	$this->db->limit(10);  // Produces: LIMIT 10
+
+The second parameter lets you set a result offset.
+
+::
+
+	$this->db->limit(10, 20);  // Produces: LIMIT 20, 10 (in MySQL.  Other databases have slightly different syntax)
+
+$this->db->count_all_results()
+==============================
+
+Permits you to determine the number of rows in a particular Active
+Record query. Queries will accept Query Builder restrictors such as
+where(), or_where(), like(), or_like(), etc. Example::
+
+	echo $this->db->count_all_results('my_table');  // Produces an integer, like 25
+	$this->db->like('title', 'match');
+	$this->db->from('my_table');
+	echo $this->db->count_all_results(); // Produces an integer, like 17
+
+$this->db->count_all()
+======================
+
+Permits you to determine the number of rows in a particular table.
+Submit the table name in the first parameter. Example::
+
+	echo $this->db->count_all('my_table');  // Produces an integer, like 25
+
+**************
+Query grouping
+**************
+
+Query grouping allows you to create groups of WHERE clauses by enclosing them in parentheses. This will allow
+you to create queries with complex WHERE clauses. Nested groups are supported. Example:
+
+	$this->db->select('*')->from('my_table')
+		->group_start()
+			->where('a', 'a')
+			->or_group_start()
+				->where('b', 'b')
+				->where('c', 'c')
+			->group_end()
+		->group_end()
+		->where('d', 'd')
+	->get();
+
+	// Generates:
+	// SELECT * FROM (`my_table`) WHERE ( `a` = 'a' OR ( `b` = 'b' AND `c` = 'c' ) ) AND `d` = 'd'
+
+.. note:: groups need to be balanced, make sure every group_start() is matched by a group_end().
+
+$this->db->group_start()
+========================
+
+Starts a new group by adding an opening parenthesis to the WHERE clause of the query.
+
+$this->db->or_group_start()
+===========================
+
+Starts a new group by adding an opening parenthesis to the WHERE clause of the query, prefixing it with 'OR'.
+
+$this->db->not_group_start()
+============================
+
+Starts a new group by adding an opening parenthesis to the WHERE clause of the query, prefixing it with 'NOT'.
+
+$this->db->or_not_group_start()
+===============================
+
+Starts a new group by adding an opening parenthesis to the WHERE clause of the query, prefixing it with 'OR NOT'.
+
+$this->db->group_end()
+======================
+
+Ends the current group by adding an closing parenthesis to the WHERE clause of the query.
+
+**************
+Inserting Data
+**************
+
+$this->db->insert()
+===================
+
+Generates an insert string based on the data you supply, and runs the
+query. You can either pass an **array** or an **object** to the
+function. Here is an example using an array::
+
+	$data = array(
+		'title' => 'My title',
+		'name' => 'My Name',
+		'date' => 'My date'
+	);
+
+	$this->db->insert('mytable', $data);
+	// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
+
+The first parameter will contain the table name, the second is an
+associative array of values.
+
+Here is an example using an object::
+
+	/*
+	class Myclass {
+		var  $title = 'My Title';
+		var  $content = 'My Content';
+		var  $date = 'My Date';
+	}
+	*/
+
+	$object = new Myclass;
+	$this->db->insert('mytable', $object);
+	// Produces: INSERT INTO mytable (title, content, date) VALUES ('My Title', 'My Content', 'My Date')
+
+The first parameter will contain the table name, the second is an
+object.
+
+.. note:: All values are escaped automatically producing safer queries.
+
+$this->db->get_compiled_insert()
+================================
+Compiles the insertion query just like `$this->db->insert()`_ but does not
+*run* the query. This method simply returns the SQL query as a string.
+
+Example::
+
+	$data = array(
+		'title' => 'My title',
+		'name'  => 'My Name',
+		'date'  => 'My date'
+	);
+
+	$sql = $this->db->set($data)->get_compiled_insert('mytable');
+	echo $sql;
+
+	// Produces string: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
+
+The second parameter enables you to set whether or not the query builder query
+will be reset (by default it will be--just like `$this->db->insert()`_)::
+
+	echo $this->db->set('title', 'My Title')->get_compiled_insert('mytable', FALSE);
+
+	// Produces string: INSERT INTO mytable (title) VALUES ('My Title')
+
+	echo $this->db->set('content', 'My Content')->get_compiled_insert();
+
+	// Produces string: INSERT INTO mytable (title, content) VALUES ('My Title', 'My Content')
+
+The key thing to notice in the above example is that the second query did not
+utlize `$this->db->from()`_ nor did it pass a table name into the first
+parameter. The reason this worked is because the query has not been executed
+using `$this->db->insert()`_ which resets values or reset directly using
+`$this->db->reset_query()`_.
+
+$this->db->insert_batch()
+=========================
+
+Generates an insert string based on the data you supply, and runs the
+query. You can either pass an **array** or an **object** to the
+function. Here is an example using an array::
+
+	$data = array(
+		array(
+			'title' => 'My title',
+			'name' => 'My Name',
+			'date' => 'My date'
+		),
+		array(
+			'title' => 'Another title',
+			'name' => 'Another Name',
+			'date' => 'Another date'
+		)
+	);
+
+	$this->db->insert_batch('mytable', $data);
+	// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'),  ('Another title', 'Another name', 'Another date')
+
+The first parameter will contain the table name, the second is an
+associative array of values.
+
+.. note:: All values are escaped automatically producing safer queries.
+
+$this->db->set()
+================
+
+This function enables you to set values for inserts or updates.
+
+**It can be used instead of passing a data array directly to the insert
+or update functions:**
+
+::
+
+	$this->db->set('name', $name);
+	$this->db->insert('mytable');  // Produces: INSERT INTO mytable (name) VALUES ('{$name}')
+
+If you use multiple function called they will be assembled properly
+based on whether you are doing an insert or an update::
+
+	$this->db->set('name', $name);
+	$this->db->set('title', $title);
+	$this->db->set('status', $status);
+	$this->db->insert('mytable');
+
+**set()** will also accept an optional third parameter ($escape), that
+will prevent data from being escaped if set to FALSE. To illustrate the
+difference, here is set() used both with and without the escape
+parameter.
+
+::
+
+	$this->db->set('field', 'field+1', FALSE);
+	$this->db->insert('mytable'); // gives INSERT INTO mytable (field) VALUES (field+1)
+	$this->db->set('field', 'field+1');
+	$this->db->insert('mytable'); // gives INSERT INTO mytable (field) VALUES ('field+1')
+
+
+You can also pass an associative array to this function::
+
+	$array = array(
+		'name' => $name,
+		'title' => $title,
+		'status' => $status
+	);
+
+	$this->db->set($array);
+	$this->db->insert('mytable');
+
+Or an object::
+
+	/*
+	class Myclass {
+		var  $title = 'My Title';
+		var  $content = 'My Content';
+		var  $date = 'My Date';
+	}
+	*/
+
+	$object = new Myclass;
+	$this->db->set($object);
+	$this->db->insert('mytable');
+
+
+*************
+Updating Data
+*************
+
+$this->db->update()
+===================
+
+Generates an update string and runs the query based on the data you
+supply. You can pass an **array** or an **object** to the function. Here
+is an example using an array::
+
+	$data = array(
+		'title' => $title,
+		'name' => $name,
+		'date' => $date
+	);
+
+	$this->db->where('id', $id);
+	$this->db->update('mytable', $data);
+	// Produces: // UPDATE mytable  // SET title = '{$title}', name = '{$name}', date = '{$date}' // WHERE id = $id
+
+Or you can supply an object::
+
+	/*
+	class Myclass {
+		var  $title = 'My Title';
+		var  $content = 'My Content';
+		var  $date = 'My Date';
+	}
+	*/
+
+	$object = new Myclass;
+	$this->db->where('id', $id);
+	$this->db->update('mytable', $object);
+	// Produces: // UPDATE mytable  // SET title = '{$title}', name = '{$name}', date = '{$date}' // WHERE id = $id
+
+.. note:: All values are escaped automatically producing safer queries.
+
+You'll notice the use of the $this->db->where() function, enabling you
+to set the WHERE clause. You can optionally pass this information
+directly into the update function as a string::
+
+	$this->db->update('mytable', $data, "id = 4");
+
+Or as an array::
+
+	$this->db->update('mytable', $data, array('id' => $id));
+
+You may also use the $this->db->set() function described above when
+performing updates.
+
+$this->db->update_batch()
+=========================
+
+Generates an update string based on the data you supply, and runs the query.
+You can either pass an **array** or an **object** to the function.
+Here is an example using an array::
+
+	$data = array(
+	   array(
+	      'title' => 'My title' ,
+	      'name' => 'My Name 2' ,
+	      'date' => 'My date 2'
+	   ),
+	   array(
+	      'title' => 'Another title' ,
+	      'name' => 'Another Name 2' ,
+	      'date' => 'Another date 2'
+	   )
+	);
+
+	$this->db->update_batch('mytable', $data, 'title');
+
+	// Produces:
+	// UPDATE `mytable` SET `name` = CASE
+	// WHEN `title` = 'My title' THEN 'My Name 2'
+	// WHEN `title` = 'Another title' THEN 'Another Name 2'
+	// ELSE `name` END,
+	// `date` = CASE
+	// WHEN `title` = 'My title' THEN 'My date 2'
+	// WHEN `title` = 'Another title' THEN 'Another date 2'
+	// ELSE `date` END
+	// WHERE `title` IN ('My title','Another title')
+
+The first parameter will contain the table name, the second is an associative
+array of values, the third parameter is the where key.
+
+.. note:: All values are escaped automatically producing safer queries.
+
+$this->db->get_compiled_update()
+================================
+
+This works exactly the same way as ``$this->db->get_compiled_insert()`` except
+that it produces an UPDATE SQL string instead of an INSERT SQL string.
+
+For more information view documentation for `$this->db->get_compiled_insert()`_.
+
+
+*************
+Deleting Data
+*************
+
+$this->db->delete()
+===================
+
+Generates a delete SQL string and runs the query.
+
+::
+
+	$this->db->delete('mytable', array('id' => $id));  // Produces: // DELETE FROM mytable  // WHERE id = $id
+
+The first parameter is the table name, the second is the where clause.
+You can also use the where() or or_where() functions instead of passing
+the data to the second parameter of the function::
+
+	$this->db->where('id', $id);
+	$this->db->delete('mytable');
+
+	// Produces:
+	// DELETE FROM mytable
+	// WHERE id = $id
+
+
+An array of table names can be passed into delete() if you would like to
+delete data from more than 1 table.
+
+::
+
+	$tables = array('table1', 'table2', 'table3');
+	$this->db->where('id', '5');
+	$this->db->delete($tables);
+
+
+If you want to delete all data from a table, you can use the truncate()
+function, or empty_table().
+
+$this->db->empty_table()
+========================
+
+Generates a delete SQL string and runs the
+query.::
+
+	  $this->db->empty_table('mytable'); // Produces: DELETE FROM mytable
+
+
+$this->db->truncate()
+=====================
+
+Generates a truncate SQL string and runs the query.
+
+::
+
+	$this->db->from('mytable');
+	$this->db->truncate();
+
+	// or
+
+	$this->db->truncate('mytable');
+
+	// Produce:
+	// TRUNCATE mytable
+
+.. note:: If the TRUNCATE command isn't available, truncate() will
+	execute as "DELETE FROM table".
+
+$this->db->get_compiled_delete()
+================================
+This works exactly the same way as ``$this->db->get_compiled_insert()`` except
+that it produces a DELETE SQL string instead of an INSERT SQL string.
+
+For more information view documentation for `$this->db->get_compiled_insert()`_.
+
+***************
+Method Chaining
+***************
+
+Method chaining allows you to simplify your syntax by connecting
+multiple functions. Consider this example::
+
+	$query = $this->db->select('title')
+				->where('id', $id)
+				->limit(10, 20)
+				->get('mytable');
+
+.. _ar-caching:
+
+*********************
+Query Builder Caching
+*********************
+
+While not "true" caching, Query Builder enables you to save (or "cache")
+certain parts of your queries for reuse at a later point in your
+script's execution. Normally, when an Query Builder call is completed,
+all stored information is reset for the next call. With caching, you can
+prevent this reset, and reuse information easily.
+
+Cached calls are cumulative. If you make 2 cached select() calls, and
+then 2 uncached select() calls, this will result in 4 select() calls.
+There are three Caching functions available:
+
+$this->db->start_cache()
+========================
+
+This function must be called to begin caching. All Query Builder queries
+of the correct type (see below for supported queries) are stored for
+later use.
+
+$this->db->stop_cache()
+=======================
+
+This function can be called to stop caching.
+
+$this->db->flush_cache()
+========================
+
+This function deletes all items from the Query Builder cache.
+
+Here's a usage example::
+
+	$this->db->start_cache();
+	$this->db->select('field1');
+	$this->db->stop_cache();
+	$this->db->get('tablename');
+	//Generates: SELECT `field1` FROM (`tablename`)
+
+	$this->db->select('field2');
+	$this->db->get('tablename');
+	//Generates:  SELECT `field1`, `field2` FROM (`tablename`)
+
+	$this->db->flush_cache();
+	$this->db->select('field2');
+	$this->db->get('tablename');
+	//Generates:  SELECT `field2` FROM (`tablename`)
+
+
+.. note:: The following statements can be cached: select, from, join,
+	where, like, group_by, having, order_by, set
+
+
+$this->db->reset_query()
+========================
+
+Resetting Query Builder allows you to start fresh with your query without
+executing it first using a method like $this->db->get() or $this->db->insert().
+Just like the methods that execute a query, this will *not* reset items you've
+cached using `Query Builder Caching`_.
+
+This is useful in situations where you are using Query Builder to generate SQL
+(ex. ``$this->db->get_compiled_select()``) but then choose to, for instance,
+run the query::
+
+	// Note that the second parameter of the get_compiled_select method is FALSE
+	$sql = $this->db->select(array('field1','field2'))
+					->where('field3',5)
+					->get_compiled_select('mytable', FALSE);
+
+	// ...
+	// Do something crazy with the SQL code... like add it to a cron script for
+	// later execution or something...
+	// ...
+
+	$data = $this->db->get()->result_array();
+
+	// Would execute and return an array of results of the following query:
+	// SELECT field1, field1 from mytable where field3 = 5;

Subject: Added support for Wincache when running CI on Windows boxes

Wincache is directly analogous to APC, except with less problems on a Windows environment. Performance wise they are almost identical (for user mode caching at least).

Need to have the Wincache PHP module downloaded from http://www.iis.net/download/wincacheforphp.

 -  Fixed a bug (#413) - Oracle's _error_message() and _error_number() methods used to only return connection-related errors.
 -  Fixed a bug (#804) - Profiler library was trying to handle objects as strings in some cases, resulting in warnings being issued by htmlspecialchars().
 -  Fixed a bug (#1101) - MySQL/MySQLi result method field_data() was implemented as if it was handling a DESCRIBE result instead of the actual result set.
+-  Fixed a bug in Oracle's :doc:`Database Forge Class <database/forge>` method _create_table() where it failed with AUTO_INCREMENT as it's not supported.

+Validating an Array (other than $_POST)

 Sometimes you may want to validate an array that does not originate from $_POST data.
 
 In this case, you can specify the array to be validated::
 	
-      $data = array(
-	      'username' => 'johndoe',
-		  'password' => 'mypassword',
-		  'passconf' => 'mypassword'

+		);
 
-      $this->form_validation->set_data($data);
+	$this->form_validation->set_data($data);

 validating $_POST data or an array.

 	 -  Added _optimize_table() support for the :doc:`Database Utility Class <database/utilities>` (rebuilds table indexes).
    -  Added a constructor to the DB_result class and moved all driver-specific properties and logic out of the base DB_driver class to allow better abstraction.
    -  Removed limit() and order_by() support for UPDATE and DELETE queries in PostgreSQL driver. Postgres does not support those features.
+   -  Removed protect_identifiers() and renamed _protect_identifiers() to it instead - it was just an alias.

 -  Fixed a bug in the :doc:`Session Library <libraries/sessions>` where a PHP E_NOTICE error was triggered by _unserialize() due to results from databases such as MSSQL and Oracle being space-padded on the right.
 -  Fixed a bug (#501) - set_rules() to check if the request method is not 'POST' before aborting, instead of depending on count($_POST) in the :doc:`Form Validation Library <libraries/form_validation>`.
+-  Fixed a bug (#940) - csrf_verify() used to set the CSRF cookie while processing a POST request with no actual POST data, which resulted in validating a request that should be considered invalid.

Subject: Bumped CodeIgniter's PHP requirement to 5.2.4. Yes I know PHP 5.4
 just came out, and yes I know PHP 5.3 has lovely features, but there are
 plenty of corporate systems running on CodeIgniter and PHP 5.3 still is not
 widely supported enough. CodeIgniter is great for distributed applications,
 and this is the highest we can reasonably go without breaking support. PHP
 5.3 will most likely happen in another year or so. Fingers crossed on that
 one anyway...

Subject: Fix test errors in Loader_test.php and URI_test.php

Change exceptions from Exception to RuntimeException since PHPUnit 3.6
doesn't like you to expect generic exceptions. The error it gives is:

InvalidArgumentException: You must not expect the generic exception class
travis-ci.org/#!/tiyowan/CodeIgniter/builds/832518

This issue addressed by using exceptions that are more specific.

-   -  MySQLi driver now supports persistent connections when running on PHP >= 5.3.
+   -  Improved support for the MySQLi driver, including:
+	 -  OOP style of the PHP extension is now used, instead of the procedural aliases.
+	 -  Server version checking is now done via ``mysqli::$server_info`` instead of running an SQL query.
+	 -  Added persistent connections support for PHP >= 5.3.
    -  Added dsn if the group connections in the config use PDO or any driver which need DSN.
    -  Improved PDO database support.
    -  Added Interbase/Firebird database support via the "interbase" driver

 -  Fixed a bug in the :doc:`Session Library <libraries/sessions>` where a PHP E_NOTICE error was triggered by _unserialize() due to results from databases such as MSSQL and Oracle being space-padded on the right.
 -  Fixed a bug (#501) - set_rules() to check if the request method is not 'POST' before aborting, instead of depending on count($_POST) in the :doc:`Form Validation Library <libraries/form_validation>`.
 -  Fixed a bug (#940) - csrf_verify() used to set the CSRF cookie while processing a POST request with no actual POST data, which resulted in validating a request that should be considered invalid.
+-  Fixed a bug in PostgreSQL's escape_str() where it didn't properly escape LIKE wild characters.

 -  Fixed a bug (#501) - set_rules() to check if the request method is not 'POST' before aborting, instead of depending on count($_POST) in the :doc:`Form Validation Library <libraries/form_validation>`.
 -  Fixed a bug (#940) - csrf_verify() used to set the CSRF cookie while processing a POST request with no actual POST data, which resulted in validating a request that should be considered invalid.
 -  Fixed a bug in PostgreSQL's escape_str() where it didn't properly escape LIKE wild characters.

 -  Fixed a bug (#1242) - read_dir() in the :doc:`Zip Library <libraries/zip>` wasn't compatible with Windows.

 -  Fixed a bug (#11, #183, #863) - CI_Form_validation::_execute() silently continued to the next rule, if a rule method/function is not found.
 -  Fixed a bug (#1242) - read_dir() in the :doc:`Zip Library <libraries/zip>` wasn't compatible with Windows.
 -  Fixed a bug (#306) - ODBC driver didn't have an _insert_batch() method, which resulted in fatal error being triggered when insert_batch() is used with it.
+-  Fixed a bug in MSSQL and SQLSrv's _truncate() where the TABLE keyword was missing.

 -  Fixed a bug (#1242) - read_dir() in the :doc:`Zip Library <libraries/zip>` wasn't compatible with Windows.
 -  Fixed a bug (#306) - ODBC driver didn't have an _insert_batch() method, which resulted in fatal error being triggered when insert_batch() is used with it.
 -  Fixed a bug in MSSQL and SQLSrv's _truncate() where the TABLE keyword was missing.
+-  Fixed a bug in PDO's trans_commit() method where it failed due to an erroneous property name.

From d947eba0bdaf9d86401fdcba9e97706905cacf9d Mon Sep 17 00:00:00 2001
From: Andrey Andreev <narf@bofh.bg>
Date: Mon, 9 Apr 2012 14:58:28 +0300
Subject: Multiple DB Forge improvements  - Replaced driver methods
 _create_database(), _drop_database(), _drop_table() and _rename_table() with
 properties  - Added defaults for the above mentioned platform-specific
 queries, so that not all drivers need to define them  - Improved support for
 the SQLite, ODBC and PDO drivers

From b457a4001ce2380e97f36b0a983b477c3e31de69 Mon Sep 17 00:00:00 2001
From: Andrey Andreev <narf@bofh.bg>
Date: Mon, 9 Apr 2012 16:11:56 +0300
Subject: DB Utility improvements  - Replaced driver methods _list_databases(),
 _optimize_table() and _repair_table() with properties  - Added defaults for
 optimize_table() and repair_table() SQL strings (FALSE, as those are mostly
 MySQL-specific)  - Added MSSQL/SQLSRV support for optimize_table() (actually
 rebuilds table indexes)  - Switched public driver methods to protected  -
 Improved CUBRID support for list_databases() as it used to only return the
 currently used database  - Minor speed improvements

Subject: Generate better conditions statement on boolean field type. Actually
 boolean field type need TRUE or FALSE value. Common DBMS (e.g., MySQL) can

 So, its better to use TRUE or FALSE value for boolean field type.

Subject: fix backtrace filtering

The backtrace was filtered to remove CI system files,
but the filter was buggy.  It would also filter out
application files which happened to contain the string "system"...
or ALL files, if the application directory is under /system/
(Perhaps the latter comes as a surprise, but it's explicitly
 mentioned in index.php and <http://codeigniter.com/wiki/mod_rewrite>).

Instead, we should test whether the file is underneath BASEPATH
(using realpath() to make sure we have the same sort of slashes).

Subject: Added support for $_SERVER['CI_ENV'] in index.php Remember this is
 entirely optional, nothing will change if you do not which to use Multiple
 Environments just like right now. If you DO set CI_ENV you can manipulate the
 switch that controls error reporting, etc, so set it to "production" on your
 live site to hide errors from users. If you don't require this logic you can
 remove it, or change it entirely to check HTTP_HOST for environment
 subdomains, or check IP address, etc.

Subject: Added a "non-DB" phpunit.xml for local testing Any developer can use
 this without having to set up DB's and have PostgreSQL installed by running:

    phpunit --configuration=tests/phpunit.xml

This just skips DB stuff, so code coverage will look lower than it is.

Subject: Direct return from mimes config, instead of using global $mimes;
 Global variables are generally a terrible idea, especially for something as
 simple as this. The mimes.php now returns an array instead of just injecting
 a variable name into the global namespace.

Subject: Added get_mimes() function to system/core/Commons.php.The MIMEs array
 from config/mimes.php is used by multiple core classes, libraries and helpers
 and each of them has implemented an own way of getting it, which is not
 needed and is hard to maintain. This also fixes issue #1411

 -  Fixed a bug (#726) - PDO put a 'dbname' argument in it's connection string regardless of the database platform in use, which made it impossible to use SQLite.

 	 -  _execute() now considers input data to be invalid if a specified rule is not found.
 	 -  Removed method is_numeric() as it exists as a native PHP function and _execute() will find and use that (the 'is_numeric' rule itself is deprecated since 1.6.1).
 	 -  Native PHP functions used as rules can now accept an additional parameter, other than the data itself.
+	 -  Updated set_rules() to accept an array of rules as well as a string.
    -  Changed the :doc:`Session Library <libraries/sessions>` to select only one row when using database sessions.
    -  Added all_flashdata() method to session class. Returns an associative array of only flashdata.

+submit a query. Most users will rarely use this function.
+
+It returns whatever the database drivers' "execute" function returns.
+That typically is TRUE/FALSE on success or failure for write type queries
+such as INSERT, DELETE or UPDATE statements (which is what it really
+should be used for) and a resource/object on success for queries with
+fetchable results.
+
+::
+
+	if ($this->db->simple_query('YOUR QUERY'))
+	{
+		echo "Success!";
+	}
+	else
+	{
+		echo "Query failed!";
+	}
+
+.. note:: PostgreSQL's pg_exec() function always returns a resource on
+	success, even for write type queries. So take that in mind if
+	you're looking for a boolean value.

 This function returns a single result row without prefetching the whole result in memory as row() does.
 If your query has more than one row, it returns the current row and moves the internal data pointer ahead. 
 The result is returned as $type could be 'object' (default) or 'array' that will return an associative array.

+
+CodeIgniter is an Application Development Framework - a toolkit - for
+people who build web sites using PHP. Its goal is to enable you to
+develop projects much faster than you could if you were writing code
+from scratch, by providing a rich set of libraries for commonly needed
+tasks, as well as a simple interface and logical structure to access
+these libraries. CodeIgniter lets you creatively focus on your project
+by minimizing the amount of code needed for a given task.

+CodeIgniter is right for you if:
+
+-  You want a framework with a small footprint.
+-  You need exceptional performance.
+-  You need broad compatibility with standard hosting accounts that run
+   a variety of PHP versions and configurations.
+-  You want a framework that requires nearly zero configuration.
+-  You want a framework that does not require you to use the command

 -  Fixed a bug (#79) - :doc:`Form Validation Library <libraries/form_validation>` didn't properly validate array fields that use associative keys or have custom indexes.
+-  Fixed a bug (#427) - :doc:`Form Validation Library <libraries/form_validation>` method ``strip_image_tags()`` was an alias to a non-existent method.

--  Fixed a bug (#697) - A wrong array key was used in the Upload library to check for mime-types.
--  Fixed a bug - form_open() compared $action against site_url() instead of base_url().
--  Fixed a bug - CI_Upload::_file_mime_type() could've failed if mime_content_type() is used for the detection and returns FALSE.

 -  Fixed a bug (#538) - Windows paths were ignored when using the :doc:`Image Manipulation Library <libraries/image_lib>` to create a new file.
 -  Fixed a bug - When database caching was enabled, $this->db->query() checked the cache before binding variables which resulted in cached queries never being found.
 -  Fixed a bug - CSRF cookie value was allowed to be any (non-empty) string before being written to the output, making code injection a risk.
 -  Fixed a bug (#726) - PDO put a 'dbname' argument in it's connection string regardless of the database platform in use, which made it impossible to use SQLite.
--  Fixed a bug - CI_DB_pdo_driver::num_rows() was not returning properly value with SELECT queries, cause it was relying on PDOStatement::rowCount().
--  Fixed a bug (#1059) - CI_Image_lib::clear() was not correctly clearing all necessary object properties, namely width and height.

-license, for the duration of the copyright, to do the following:
-
-	*a)* to reproduce the Original Work in copies, either alone or as part of
-	a collective work;
-
-	*b)* to translate, adapt, alter, transform, modify, or arrange the
-	Original Work, thereby creating derivative works ("Derivative Works")
-	based upon the Original Work;

-2) Grant of Patent License
-**************************
-
-Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
-license, under patent claims owned or controlled by the Licensor that are
-embodied in the Original Work as furnished by the Licensor, for the duration
-of the patents, to make, use, sell, offer for sale, have made, and import the
-Original Work and Derivative Works.
-
-
-*******************************
-3) Grant of Source Code License
-*******************************
-
-The term "Source Code" means the preferred form of the Original Work for
-making modifications to it and all available documentation describing how to
-modify the Original Work. Licensor agrees to provide a machine-readable copy
-of the Source Code of the Original Work along with each copy of the Original
-Work that Licensor distributes. Licensor reserves the right to satisfy this
-obligation by placing a machine-readable copy of the Source Code in an
-information repository reasonably calculated to permit inexpensive and
-convenient access by You for as long as Licensor continues to distribute the
-Original Work.
-
-
-********************************
-4) Exclusions From License Grant
-********************************
-
-Neither the names of Licensor, nor the names of any contributors to the
-Original Work, nor any of their trademarks or service marks, may be used to
-endorse or promote products derived from this Original Work without express
-prior permission of the Licensor. Except as expressly stated herein, nothing
-in this License grants any license to Licensor's trademarks, copyrights,
-patents, trade secrets or any other intellectual property. No patent license
-is granted to make, use, sell, offer for sale, have made, or import
-embodiments of any patent claims other than the licensed claims defined in
-Section 2) No license is granted to the trademarks of Licensor even if such
-marks are included in the Original Work. Nothing in this License shall be
-interpreted to prohibit Licensor from licensing under terms different from
-this License any Original Work that Licensor otherwise would have a right to
-license.
-
-
-**********************
-5) External Deployment
-**********************
-
-The term "External Deployment" means the use, distribution, or communication
-of the Original Work or Derivative Works in any way such that the Original
-Work or Derivative Works may be used by anyone other than You, whether those
-works are distributed or communicated to those persons or made available as an
-application intended for use over a network. As an express condition for the
-grants of license hereunder, You must treat any External Deployment by You of
-the Original Work or a Derivative Work as a distribution under section 1(c).
-
-
-*********************
-6) Attribution Rights
-*********************
-
-You must retain, in the Source Code of any Derivative Works that You create,
-all copyright, patent, or trademark notices from the Source Code of the
-Original Work, as well as any notices of licensing and any descriptive text
-identified therein as an "Attribution Notice." You must cause the Source Code
-for any Derivative Works that You create to carry a prominent Attribution
-Notice reasonably calculated to inform recipients that You have modified the
-Original Work.

-7) Warranty of Provenance and Disclaimer of Warranty
-****************************************************
-
-Licensor warrants that the copyright in and to the Original Work and the
-patent rights granted herein by Licensor are owned by the Licensor or are
-sublicensed to You under the terms of this License with the permission of the
-contributor(s) of those copyrights and patent rights. Except as expressly
-stated in the immediately preceding sentence, the Original Work is provided
-under this License on an "AS IS" BASIS and WITHOUT WARRANTY, either express or
-implied, including, without limitation, the warranties of non-infringement,
-merchantability or fitness for a particular purpose. THE ENTIRE RISK AS TO THE
-QUALITY OF THE ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY
-constitutes an essential part of this License. No license to the Original Work
-is granted by this License except under this disclaimer.
-
-
-**************************
-8) Limitation of Liability
-**************************
-
-Under no circumstances and under no legal theory, whether in tort (including
-negligence), contract, or otherwise, shall the Licensor be liable to anyone
-for any indirect, special, incidental, or consequential damages of any
-character arising as a result of this License or the use of the Original Work
-including, without limitation, damages for loss of goodwill, work stoppage,
-computer failure or malfunction, or any and all other commercial damages or
-losses. This limitation of liability shall not apply to the extent applicable
-law prohibits such limitation.
-
-
-*****************************
-9) Acceptance and Termination
-*****************************
-
-If, at any time, You expressly assented to this License, that assent indicates
-your clear and irrevocable acceptance of this License and all of its terms and
-conditions. If You distribute or communicate copies of the Original Work or a
-Derivative Work, You must make a reasonable effort under the circumstances to
-obtain the express assent of recipients to the terms of this License. This
-License conditions your rights to undertake the activities listed in Section
-1, including your right to create Derivative Works based upon the Original
-Work, and doing so without honoring these terms and conditions is prohibited
-by copyright law and international treaty. Nothing in this License is intended
-to affect copyright exceptions and limitations (including "fair use" or "fair
-dealing"). This License shall terminate immediately and You may no longer
-exercise any of the rights granted to You by this License upon your failure to
-honor the conditions in Section 1(c).
-
-
-*********************************
-10) Termination for Patent Action
-*********************************
-
-This License shall terminate automatically and You may no longer exercise any
-of the rights granted to You by this License as of the date You commence an
-action, including a cross-claim or counterclaim, against Licensor or any
-licensee alleging that the Original Work infringes a patent. This termination
-provision shall not apply for an action alleging patent infringement by
-combinations of the Original Work with other software or hardware.

-
-*****************************************
-11) Jurisdiction, Venue and Governing Law
-*****************************************
-
-Any action or suit relating to this License may be brought only in the courts
-of a jurisdiction wherein the Licensor resides or in which Licensor conducts
-its primary business, and under the laws of that jurisdiction excluding its
-conflict-of-law provisions. The application of the United Nations Convention
-on Contracts for the International Sale of Goods is expressly excluded. Any
-use of the Original Work outside the scope of this License or after its
-termination shall be subject to the requirements and penalties of copyright or
-patent law in the appropriate jurisdiction. This section shall survive the
-termination of this License.
-
-
-*******************
-12) Attorneys' Fees
-*******************
-
-In any action to enforce the terms of this License or seeking damages relating
-thereto, the prevailing party shall be entitled to recover its costs and
-expenses, including, without limitation, reasonable attorneys' fees and costs
-incurred in connection with such action, including any appeal of such action.
-This section shall survive the termination of this License.
-
-
-*****************
-13) Miscellaneous
-*****************
-
-If any provision of this License is held to be unenforceable, such provision
-shall be reformed only to the extent necessary to make it enforceable.
-
-
-***************************************
-14) Definition of "You" in This License
-***************************************
-
-"You" throughout this License, whether in upper or lower case, means an
-individual or a legal entity exercising rights under, and complying with all
-of the terms of, this License. For legal entities, "You" includes any entity
-that controls, is controlled by, or is under common control with you. For
-purposes of this definition, "control" means (i) the power, direct or
-indirect, to cause the direction or management of such entity, whether by
-contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the
-outstanding shares, or (iii) beneficial ownership of such entity.
-
-
-****************
-15) Right to Use
-****************
-
-You may use the Original Work in all ways not otherwise restricted or
-conditioned by this License or by law, and Licensor promises not to interfere
-with or be responsible for such uses by You.
-
-
-********************************
-16) Modification of This License
-********************************
-
-This License is Copyright © 2005 Lawrence Rosen. Permission is granted to
-copy, distribute, or communicate this License without modification. Nothing in
-this License permits You to modify this License as applied to the Original
-Work or to Derivative Works. However, You may modify the text of this License
-and copy, distribute or communicate your modified version (the "Modified
-License") and apply it to other original works of authorship subject to the
-following conditions: (i) You may not indicate in any way that your Modified
-License is the "Academic Free License" or "AFL" and you may not use those
-names in the name of your Modified License; (ii) You must replace the notice
-specified in the first paragraph above with the notice "Licensed under <insert
-your license name here>" or with a notice of your own that is not confusingly
-similar to the notice in this License; and (iii) You may not claim that your
-original works are open source software unless your Modified License has been
-approved by Open Source Initiative (OSI) and You comply with its license
-review and certification process.

+CodeIgniter fork.

+	git commit -s
+
+This will sign your commits with the information setup in your git config, e.g.

+
+If you are using Tower there is a "Sign-Off" checkbox in the commit window. You

+###########################
+Contributing to CodeIgniter
+###########################
+
+CodeIgniter is a community driven project and accepts contributions of code
+and documentation from the community. These contributions are made in the form
+of Issues or `Pull Requests <http://help.github.com/send-pull-requests/>`_ on
+the `EllisLab CodeIgniter repository
+<https://github.com/EllisLab/CodeIgniter>`_ on GitHub.
+
+Issues are a quick way to point out a bug. If you find a bug or documentation
+error in CodeIgniter then please check a few things first:
+
+- There is not already an open Issue
+- The issue has already been fixed (check the develop branch, or look for
+  closed Issues)
+- Is it something really obvious that you fix it yourself?
+
+Reporting issues is helpful but an even better approach is to send a Pull
+Request, which is done by "Forking" the main repository and committing to your
+own copy. This will require you to use the version control system called Git.
+
+**********
+Guidelines
+**********
+
+Before we look into how, here are the guidelines. If your Pull Requests fail
+to pass these guidelines it will be declined and you will need to re-submit
+when you’ve made the changes. This might sound a bit tough, but it is required
+for us to maintain quality of the code-base.
+
+PHP Style
+=========
+
+All code must meet the `Style Guide
+<http://codeigniter.com/user_guide/general/styleguide.html>`_, which is
+essentially the `Allman indent style
+<http://en.wikipedia.org/wiki/Indent_style#Allman_style>`_, underscores and
+readable operators. This makes certain that all code is the same format as the
+existing code and means it will be as readable as possible.
+
+Documentation
+=============
+
+If you change anything that requires a change to documentation then you will
+need to add it. New classes, methods, parameters, changing default values, etc
+are all things that will require a change to documentation. The change-log
+must also be updated for every change. Also PHPDoc blocks must be maintained.
+
+Compatibility
+=============
+
+CodeIgniter is compatible with PHP 5.2.4 so all code supplied must stick to
+this requirement. If PHP 5.3 or 5.4 functions or features are used then there
+must be a fallback for PHP 5.2.4.
+
+Branching
+=========
+
+CodeIgniter uses the `Git-Flow
+<http://nvie.com/posts/a-successful-git-branching-model/>`_ branching model
+which requires all pull requests to be sent to the "develop" branch. This is
+where the next planned version will be developed. The "master" branch will
+always contain the latest stable version and is kept clean so a "hotfix" (e.g:
+an emergency security patch) can be applied to master to create a new version,
+without worrying about other features holding it up. For this reason all
+commits need to be made to "develop" and any sent to "master" will be closed
+automatically. If you have multiple changes to submit, please place all
+changes into their own branch on your fork.
+
+One thing at a time: A pull request should only contain one change. That does
+not mean only one commit, but one change - however many commits it took. The
+reason for this is that if you change X and Y but send a pull request for both
+at the same time, we might really want X but disagree with Y, meaning we
+cannot merge the request. Using the Git-Flow branching model you can create
+new branches for both of these features and send two requests.
+
+Signing
+=======
+You must sign your work, certifying that you either wrote the work or
+otherwise have the right to pass it on to an open source project. git makes
+this trivial as you merely have to use `--signoff` on your commits to your
+CodeIgniter fork.
+
+.. code-block:: bash
+
+	git commit --signoff
+
+or simply
+
+.. code-block:: bash
+
+	git commit -s
+
+This will sign your commits with the information setup in your git config, e.g.
+
+	Signed-off-by: John Q Public <john.public@example.com>
+
+If you are using Tower there is a "Sign-Off" checkbox in the commit window. You 
+could even alias git commit to use the -s flag so you don’t have to think about 
+it.
+
+By signing your work in this manner, you certify to a "Developer's Certificate 
+or Origin". The current version of this certificate is in the :doc:`/DCO` file
+in the root of this documentation.

+Academic Free License ("AFL") v 3.0
+###################################
+
+This Academic Free License (the "License") applies to any original work of
+authorship (the "Original Work") whose owner (the "Licensor") has placed the
+following licensing notice adjacent to the copyright notice for the Original
+Work:
+
+*Licensed under the Academic Free License version 3.0*
+
+
+*****************************
+1) Grant of Copyright License
+*****************************
+
+Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
+license, for the duration of the copyright, to do the following:
+
+	*a)* to reproduce the Original Work in copies, either alone or as part of
+	a collective work;
+
+	*b)* to translate, adapt, alter, transform, modify, or arrange the
+	Original Work, thereby creating derivative works ("Derivative Works")
+	based upon the Original Work;
+
+	*c)* to distribute or communicate copies of the Original Work and
+	Derivative Works to the public, *under any license of your choice that
+	does not contradict the terms and conditions, including Licensor's
+	reserved rights and remedies, in this Academic Free License*;
+
+	*d)* to perform the Original Work publicly; and
+
+	*e)* to display the Original Work publicly.
+
+
+**************************
+2) Grant of Patent License
+**************************
+
+Licensor grants You a worldwide, royalty-free, non-exclusive, sublicensable
+license, under patent claims owned or controlled by the Licensor that are
+embodied in the Original Work as furnished by the Licensor, for the duration
+of the patents, to make, use, sell, offer for sale, have made, and import the
+Original Work and Derivative Works.
+
+
+*******************************
+3) Grant of Source Code License
+*******************************
+
+The term "Source Code" means the preferred form of the Original Work for
+making modifications to it and all available documentation describing how to
+modify the Original Work. Licensor agrees to provide a machine-readable copy
+of the Source Code of the Original Work along with each copy of the Original
+Work that Licensor distributes. Licensor reserves the right to satisfy this
+obligation by placing a machine-readable copy of the Source Code in an
+information repository reasonably calculated to permit inexpensive and
+convenient access by You for as long as Licensor continues to distribute the
+Original Work.
+
+
+********************************
+4) Exclusions From License Grant
+********************************
+
+Neither the names of Licensor, nor the names of any contributors to the
+Original Work, nor any of their trademarks or service marks, may be used to
+endorse or promote products derived from this Original Work without express
+prior permission of the Licensor. Except as expressly stated herein, nothing
+in this License grants any license to Licensor's trademarks, copyrights,
+patents, trade secrets or any other intellectual property. No patent license
+is granted to make, use, sell, offer for sale, have made, or import
+embodiments of any patent claims other than the licensed claims defined in
+Section 2) No license is granted to the trademarks of Licensor even if such
+marks are included in the Original Work. Nothing in this License shall be
+interpreted to prohibit Licensor from licensing under terms different from
+this License any Original Work that Licensor otherwise would have a right to
+license.
+
+
+**********************
+5) External Deployment
+**********************
+
+The term "External Deployment" means the use, distribution, or communication
+of the Original Work or Derivative Works in any way such that the Original
+Work or Derivative Works may be used by anyone other than You, whether those
+works are distributed or communicated to those persons or made available as an
+application intended for use over a network. As an express condition for the
+grants of license hereunder, You must treat any External Deployment by You of
+the Original Work or a Derivative Work as a distribution under section 1(c).
+
+
+*********************
+6) Attribution Rights
+*********************
+
+You must retain, in the Source Code of any Derivative Works that You create,
+all copyright, patent, or trademark notices from the Source Code of the
+Original Work, as well as any notices of licensing and any descriptive text
+identified therein as an "Attribution Notice." You must cause the Source Code
+for any Derivative Works that You create to carry a prominent Attribution
+Notice reasonably calculated to inform recipients that You have modified the
+Original Work.
+
+
+****************************************************
+7) Warranty of Provenance and Disclaimer of Warranty
+****************************************************
+
+Licensor warrants that the copyright in and to the Original Work and the
+patent rights granted herein by Licensor are owned by the Licensor or are
+sublicensed to You under the terms of this License with the permission of the
+contributor(s) of those copyrights and patent rights. Except as expressly
+stated in the immediately preceding sentence, the Original Work is provided
+under this License on an "AS IS" BASIS and WITHOUT WARRANTY, either express or
+implied, including, without limitation, the warranties of non-infringement,
+merchantability or fitness for a particular purpose. THE ENTIRE RISK AS TO THE
+QUALITY OF THE ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY
+constitutes an essential part of this License. No license to the Original Work
+is granted by this License except under this disclaimer.
+
+
+**************************
+8) Limitation of Liability
+**************************
+
+Under no circumstances and under no legal theory, whether in tort (including
+negligence), contract, or otherwise, shall the Licensor be liable to anyone
+for any indirect, special, incidental, or consequential damages of any
+character arising as a result of this License or the use of the Original Work
+including, without limitation, damages for loss of goodwill, work stoppage,
+computer failure or malfunction, or any and all other commercial damages or
+losses. This limitation of liability shall not apply to the extent applicable
+law prohibits such limitation.
+
+
+*****************************
+9) Acceptance and Termination
+*****************************
+
+If, at any time, You expressly assented to this License, that assent indicates
+your clear and irrevocable acceptance of this License and all of its terms and
+conditions. If You distribute or communicate copies of the Original Work or a
+Derivative Work, You must make a reasonable effort under the circumstances to
+obtain the express assent of recipients to the terms of this License. This
+License conditions your rights to undertake the activities listed in Section
+1, including your right to create Derivative Works based upon the Original
+Work, and doing so without honoring these terms and conditions is prohibited
+by copyright law and international treaty. Nothing in this License is intended
+to affect copyright exceptions and limitations (including "fair use" or "fair
+dealing"). This License shall terminate immediately and You may no longer
+exercise any of the rights granted to You by this License upon your failure to
+honor the conditions in Section 1(c).
+
+
+*********************************
+10) Termination for Patent Action
+*********************************
+
+This License shall terminate automatically and You may no longer exercise any
+of the rights granted to You by this License as of the date You commence an
+action, including a cross-claim or counterclaim, against Licensor or any

+provision shall not apply for an action alleging patent infringement by
+combinations of the Original Work with other software or hardware.
+
+
+*****************************************

+conflict-of-law provisions. The application of the United Nations Convention
+on Contracts for the International Sale of Goods is expressly excluded. Any
+use of the Original Work outside the scope of this License or after its
+termination shall be subject to the requirements and penalties of copyright or
+patent law in the appropriate jurisdiction. This section shall survive the
+termination of this License.
+
+
+*******************
+12) Attorneys' Fees
+*******************
+
+In any action to enforce the terms of this License or seeking damages relating
+thereto, the prevailing party shall be entitled to recover its costs and
+expenses, including, without limitation, reasonable attorneys' fees and costs
+incurred in connection with such action, including any appeal of such action.
+This section shall survive the termination of this License.
+
+
+*****************
+13) Miscellaneous
+*****************
+
+If any provision of this License is held to be unenforceable, such provision
+shall be reformed only to the extent necessary to make it enforceable.
+
+
+***************************************
+14) Definition of "You" in This License
+***************************************
+
+"You" throughout this License, whether in upper or lower case, means an
+individual or a legal entity exercising rights under, and complying with all
+of the terms of, this License. For legal entities, "You" includes any entity
+that controls, is controlled by, or is under common control with you. For
+purposes of this definition, "control" means (i) the power, direct or
+indirect, to cause the direction or management of such entity, whether by
+contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the
+outstanding shares, or (iii) beneficial ownership of such entity.
+
+
+****************
+15) Right to Use
+****************
+
+You may use the Original Work in all ways not otherwise restricted or
+conditioned by this License or by law, and Licensor promises not to interfere
+with or be responsible for such uses by You.
+
+
+********************************
+16) Modification of This License
+********************************
+
+This License is Copyright © 2005 Lawrence Rosen. Permission is granted to
+copy, distribute, or communicate this License without modification. Nothing in
+this License permits You to modify this License as applied to the Original
+Work or to Derivative Works. However, You may modify the text of this License
+and copy, distribute or communicate your modified version (the "Modified
+License") and apply it to other original works of authorship subject to the
+following conditions: (i) You may not indicate in any way that your Modified
+License is the "Academic Free License" or "AFL" and you may not use those
+names in the name of your Modified License; (ii) You must replace the notice
+specified in the first paragraph above with the notice "Licensed under <insert
+your license name here>" or with a notice of your own that is not confusingly
+similar to the notice in this License; and (iii) You may not claim that your
+original works are open source software unless your Modified License has been
+approved by Open Source Initiative (OSI) and You comply with its license
+review and certification process.

+***************************************************************
+Step 7: Remove usage of (previously) deprecated functionalities
+***************************************************************
+
+In addition to the ``$autoload['core']`` configuration setting, there's a number of other functionalities
+that have been removed in CodeIgniter 3.0.0:
+
+The SHA1 library
+================
+
+The previously deprecated SHA1 library has been removed, alter your code to use PHP's native
+``sha1()`` function to generate a SHA1 hash.
+
+Additionally, the ``sha1()`` method in the :doc:`Encryption Library <../libraries/encryption>` has been removed.
+
+The EXT constant
+================
+
+Usage of the ``EXT`` constant has been deprecated since dropping support for PHP 4. There's no
+longer a need to maintain different filename extensions and in this new CodeIgniter version,
+the ``EXT`` constant has been removed. Use just '.php' instead.
+
+Smiley helper js_insert_smiley()
+================================
+
+:doc:`Smiley Helper <../helpers/smiley_helper>` function ``js_insert_smiley()`` has been deprecated
+since CodeIgniter 1.7.2 and is now removed. You'll need to switch to ``smiley_js()`` instead.
+
+Security helper do_hash()
+=========================
+
+:doc:`Security Helper <../helpers/security_helper>` function ``do_hash()`` is now just an alias for
+PHP's native ``hash()`` function. It is deprecated and scheduled for removal in CodeIgniter 3.1+.
+
+.. note:: This function is still available, but you're strongly encouraged to remove it's usage sooner
+	rather than later.
+
+File helper read_file()
+=======================
+
+:doc:`File Helper <../helpers/file_helper>` function ``read_file()`` is now just an alias for
+PHP's native ``file_get_contents()`` function. It is deprecated and scheduled for removal in
+CodeIgniter 3.1+.
+
+.. note:: This function is still available, but you're strongly encouraged to remove it's usage sooner
+	rather than later.
+
+Pagination library 'anchor_class' setting
+=========================================
+
+The :doc:`Pagination Library <../libraries/pagination>` now supports adding pretty much any HTML
+attribute to your anchors via the 'attributes' configuration setting. This includes passing the
+'class' attribute and using the separate 'anchor_class' setting no longer makes sense.
+As a result of that, the 'anchor_class' setting is now deprecated and scheduled for removal in
+CodeIgniter 3.1+.
+
+.. note:: This setting is still available, but you're strongly encouraged to remove it's usage sooner
+	rather than later.

Subject: Having `"0"` in an array would give you NULL with `elements()`. BAD!
 The trouble here, is that when we are expecting a valid result, such as `0`,
 or `false` that the array helper will instead say "I don't know if there is a
 value" and give you a `null`.

 	 - Generally improved for speed and cleaned up all of its components.
-	 - *Row* result methods now really only fetch only the needed number of rows, instead of depending entirely on result().
 	 - num_rows() is now only called explicitly by the developer and no longer re-executes statements.
    -  Improved support of the SQLite driver, including:

 	 -  Removed method is_numeric() as it exists as a native PHP function and _execute() will find and use that (the 'is_numeric' rule itself is deprecated since 1.6.1).
 	 -  Native PHP functions used as rules can now accept an additional parameter, other than the data itself.
 	 -  Updated set_rules() to accept an array of rules as well as a string.
+	 -  Fields that have empty rules set no longer run through validation (and therefore are not considered erroneous).
    -  Changed the :doc:`Session Library <libraries/sessions>` to select only one row when using database sessions.
    -  Added all_flashdata() method to session class. Returns an associative array of only flashdata.
    -  Allowed for setting table class defaults in a config file.

Subject: Logging should obey error_reporting() setting

+Callbacks
+=========
+
+If you are using PHP >= 5.3 you can use callbacks in place of the normal routing
+rules to process the back-references. Example::
+
+	$route['products/([a-z]+)/edit/(\d+)'] = function($product_type, $id){

 If the third (optional) parameter is blank, the library will usually be
 assigned to an object with the same name as the library. For example, if
+the library is named Calendar, it will be assigned to a variable named
+$this->calendar.
+
+If you prefer to set your own class names you can pass its value to the

+$this->load->driver('parent_name', $config, 'object name')
+===========================================================
+
+This function is used to load driver libraries. Where parent_name is the
+name of the parent class you want to load.
+
+As an example, if you would like to use sessions with CodeIgniter, the first
+step is to load the session driver within your controller::
+
+	$this->load->driver('session');
+
+Once loaded, the library will be ready for use, using
+$this->session->*some_function*().
+
+Driver files must be stored in a subdirectory within the main
+"libraries" folder, or within your personal application/libraries
+folder. The subdirectory must match the parent class name. Read the
+:doc:`Drivers <../general/drivers>` description for details.
+
+Additionally, multiple driver libraries can be loaded at the same time by
+passing an array of drivers to the load function.
+
+::
+
+	$this->load->driver(array('session', 'cache'));
+
+Setting options
+---------------
+
+The second (optional) parameter allows you to optionally pass
+configuration settings. You will typically pass these as an array::
+
+	$config = array (
+	                  'sess_driver' => 'cookie',
+	                  'sess_encrypt_cookie'  => true,

+	               );
+
+	$this->load->driver('session', $config);
+
+Config options can usually also be set via a config file. Each library
+is explained in detail in its own page, so please read the information
+regarding each one you would like to use.
+
+Assigning a Driver to a different object name
+----------------------------------------------

+=========================== =============== ==========================================================================
+
+Session Drivers
+===============
+
+By default, the `Cookie Driver`_ is loaded when a session is initialized.
+However, any valid driver may be selected with the $config['sess_driver']
+line in your config.php file.
+
+The session driver library comes with the cookie and native drivers
+installed, and `Custom Drivers`_ may also be installed by the user.
+
+Typically, only one driver will be used at a time, but CodeIgniter does
+support loading multiple drivers. If a specific valid driver is called, it
+will be automatically loaded. Or, an additional driver may be explicitly
+loaded by calling load_driver()::
+
+	$this->session->load_driver('native');
+
+The Session library keeps track of the most recently selected driver to call
+for driver methods. Normally, session class methods are called directly on
+the parent class, as illustrated above. However, any methods called through
+a specific driver will select that driver before invoking the parent method.
+
+So, alternation between multiple drivers can be achieved by specifying which
+driver to use for each call::
+
+	$this->session->native->set_userdata('foo', 'bar');
+
+	$this->session->cookie->userdata('foo');
+
+	$this->session->native->unset_userdata('foo');
+
+Notice in the previous example that the *native* userdata value 'foo'
+would be set to 'bar', which would NOT be returned by the call for
+the *cookie* userdata 'foo', nor would the *cookie* value be unset by
+the call to unset the *native* 'foo' value. The drivers maintain independent
+sets of values, regardless of key names.
+
+A specific driver may also be explicitly selected for use by pursuant
+methods with the select_driver() call::
+
+	$this->session->select_driver('native');
+
+	$this->session->userdata('item');	// Uses the native driver
+
+Cookie Driver
+-------------
+
+The Cookie driver stores session information for each user as serialized
+(and optionally encrypted) data in a cookie. It can also store the session
+data in a database table for added security, as this permits the session ID
+in the user's cookie to be matched against the stored session ID. By default
+only the cookie is saved. If you choose to use the database option you'll
+need to create the session table as indicated below.
+
+If you have the encryption option enabled, the serialized array will be
+encrypted before being stored in the cookie, making the data highly
+secure and impervious to being read or altered by someone. More info
+regarding encryption can be :doc:`found here <encryption>`, although
+the Session class will take care of initializing and encrypting the data
+automatically.
+
+.. note:: Even if you are not using encrypted sessions, you must set
+	an :doc:`encryption key <./encryption>` in your config file which is used
+	to aid in preventing session data manipulation.
+
+.. note:: Cookies can only hold 4KB of data, so be careful not to exceed
+	the capacity. The encryption process in particular produces a longer
+	data string than the original so keep careful track of how much data you
+	are storing.

+pairs with some sort of storage mechanism.
 
-Session Preferences
-===================
+To make a new driver, extend CI_Session_driver. Overload the initialize
+method and read or create session data. Then implement a save handler to
+write changed data to storage (sess_save), a destroy handler to remove
+deleted data (sess_destroy), a regenerate handler to make a new session ID,
+and an access handler to expose the data (get_userdata). Your initial class
+might look like::
 
-You'll find the following Session related preferences in your
-application/config/config.php file:
+	class CI_Session_custom extends CI_Session_driver {
+		protected function initialize()
+		{
+			// Read existing session data or create a new one
+		}
+
+		public function sess_save()
+		{
+			// Save current data to storage
+		}
+
+		public function sess_destroy()
+		{
+			// Destroy the current session and clean up storage
+		}
+
+		public function sess_regenerate()
+		{
+			// Create new session ID
+		}
+
+		public function &get_userdata()
+		{
+			// Return a reference to your userdata array
+		}
+	}
+
+Notice that get_userdata() returns a reference so the parent library is
+accessing the same array the driver object is using. This saves memory
+and avoids synchronization issues during usage.
+
+Put your driver in the libraries/Session/drivers folder anywhere in your
+package paths. This includes the application directory, the system directory,
+or any path you add with $CI->load->add_package_path(). Your driver must be
+named CI_Session_<name>, and your filename must be Session_<name>.php,
+preferably also capitalized, such as::
+
+	CI_Session_foo in libraries/Session/drivers/Session_foo.php
+
+Then specify the driver by setting 'sess_driver' in your config.php file or as a
+parameter when loading the CI_Session object::
+
+	$config['sess_driver'] = 'foo';
+
+OR::
+
+	$CI->load->driver('session', array('sess_driver' => 'foo'));
+
+The driver specified by 'sess_driver' is automatically included as a valid
+driver. However, if you want to make a custom driver available as an option
+without making it the initially loaded driver, set 'sess_valid_drivers' in
+your config.php file to an array including your driver name::
+
+	$config['sess_valid_drivers'] = array('sess_driver');

    -  Replaced the _error_message() and _error_number() methods with error(), that returns an array containing the last database error code and message.
    -  Improved version() implementation so that drivers that have a native function to get the version number don't have to be defined in the core DB_driver class.
    -  Improved support of the PostgreSQL driver, including:
-	 - pg_version() is now used to get the database version number, when possible.
-	 - Added db_set_charset() support.
-	 - Added support for optimize_table() in :doc:`Database Utilities <database/utilities>` (rebuilds table indexes).
-	 - Added boolean data type support in escape().
-	 - Added update_batch() support.
-	 - Removed limit() and order_by() support for UPDATE and DELETE queries in as PostgreSQL does not support those features.
+	 - ``pg_version()`` is now used to get the database version number, when possible.
+	 - Added ``db_set_charset()`` support.

+	 - Removed ``limit()`` and ``order_by()`` support for UPDATE and DELETE queries as PostgreSQL does not support those features.
+	 - Added a work-around for dead persistent connections to be re-created after a database restart.
    -  Added a constructor to the DB_result class and moved all driver-specific properties and logic out of the base DB_driver class to allow better abstraction.
    -  Removed protect_identifiers() and renamed internal method _protect_identifiers() to it instead - it was just an alias.
    -  Renamed internal method _escape_identifiers() to escape_identifiers().

- added .highlighted class to CSS for highlighting search terms
- replaced Google search form with native search form (and separated into its own theme file)

+Step 4: Add new session driver items to your config/config.php
+**************************************************************
+
+With the change from a single Session Library to the new Session Driver, two new config items have been added:
+
+   -  ``$config['sess_driver']`` selects which driver to initially load. Options are:
+       -  'cookie' (the default) for classic CodeIgniter cookie-based sessions
+       -  'native' for native PHP Session support
+       -  the name of a custom driver you have provided (see :doc:`Session Driver <../libraries/sessions>` for more info)
+   -  ``$config['sess_valid_drivers']`` provides an array of additional custom drivers to make available for loading
+
+As the new Session Driver library loads the classic Cookie driver by default and always makes 'cookie' and 'native'
+available as valid drivers, neither of these configuration items are required. However, it is recommended that you
+add them for clarity and ease of configuration in the future.

 Migrations Class
 ################
 
-Coming soon.
\ No newline at end of file
+Migrations are a convenient way for you to alter your database in a 
+structured and organized manner. You could edit fragments of SQL by hand 
+but you would then be responsible for telling other developers that they 
+need to go and run them. You would also have to keep track of which changes 
+need to be run against the production machines next time you deploy.
+
+The database table **migration** tracks which migrations have already been 
+run so all you have to do is update your application files and 
+call **$this->migrate->current()** to work out which migrations should be run. 
+The current version is found in **config/migration.php**.
+
+******************
+Create a Migration
+******************
+
+.. note:: Each Migration is run in numerical order forward or backwards 
+	depending on the method taken. Use a prefix of 3 numbers followed by an 
+	underscore for the filename of your migration.
+	
+This will be the first migration for a new site which has a blog. All 
+migrations go in the folder **application/migrations/** and have names such 
+as: **001_add_blog.php**.::
+
+	defined('BASEPATH') OR exit('No direct script access allowed');
+
+	class Migration_Add_blog extends CI_Migration {
+
+		public function up()
+		{
+			$this->dbforge->add_field(array(
+				'blog_id' => array(
+					'type' => 'INT',
+					'constraint' => 5,
+					'unsigned' => TRUE,
+					'auto_increment' => TRUE
+				),
+				'blog_title' => array(
+					'type' => 'VARCHAR',
+					'constraint' => '100',
+				),
+				'blog_description' => array(
+					'type' => 'TEXT',
+					'null' => TRUE,
+				),
+			));
+			
+			$this->dbforge->create_table('blog');
+		}
+
+		public function down()
+		{
+			$this->dbforge->drop_table('blog');
+		}
+
+Then in **application/config/migration.php** set **$config['migration_version'] = 1;**.
+
+*************
+Usage Example
+*************
+
+In this example some simple code is placed in **application/controllers/migrate.php** 
+to update the schema.::
+
+	$this->load->library('migration');
+
+	if ( ! $this->migration->current())
+	{
+		show_error($this->migration->error_string());
+	}
+
+******************
+Function Reference
+******************
+
+There are five available methods for the Migration class:
+
+-  $this->migration->current();
+-  $this->migration->error_string();
+-  $this->migration->find_migrations();
+-  $this->migration->latest();
+-  $this->migration->version();
+
+$this->migration->current()
+============================
+
+The current migration is whatever is set for **$config['migration_version']** in 
+**application/config/migration.php**.
+
+$this->migration->error_string()
+=================================
+
+This returns a string of errors while performing a migration.
+
+$this->migration->find_migrations()
+====================================
+
+An array of migration filenames are returned that are found in the **migration_path** 
+property.
+
+$this->migration->latest()
+===========================
+
+This works much the same way as current() but instead of looking for 
+the **$config['migration_version']** the Migration class will use the very 
+newest migration found in the filesystem.
+
+$this->migration->version()
+============================
+
+Version can be used to roll back changes or step forwards programmatically to 
+specific versions. It works just like current but ignores **$config['migration_version']**.::
+
+	$this->load->library('migration');
+
+	$this->migration->version(5);
+
+*********************
+Migration Preferences
+*********************
+
+The following is a table of all the config options for migrations.
+
+========================== ====================== ============= =============================================
+Preference                 Default                Options       Description
+========================== ====================== ============= =============================================
+**migration_enabled**      FALSE                  TRUE / FALSE  Enable or disable migrations.
+**migration_path**         APPPATH.'migrations/'  None          The path to your migrations folder.
+**migration_version**      0                      None          The current version your database should use.
+**migration_table**        migrations             None          The table name for storing the shema
+                                                                version number.
+**migration_auto_latest**  FALSE                  TRUE / FALSE  Enable or disable automatically 
+                                                                running migrations.

Subject: Better server test in redirect() of URL helper

"Location" header bugs are specific to IIS; previous test was matching
all HTTP servers under Windows.

This test isn't perfect yet ($_SERVER['SERVER_SOFTWARE'], which
corresponds to the "Server" header of HTTP response, might be missing),
but there is no perfect test.

"Refresh" method makes the window blank for quite a noticeable time,
so let's not affect other servers because of IIS.

+###########################
+Contributing to CodeIgniter
+###########################
+
+CodeIgniter is a community driven project and accepts contributions of code
+and documentation from the community. These contributions are made in the form
+of Issues or `Pull Requests <http://help.github.com/send-pull-requests/>`_ on
+the `EllisLab CodeIgniter repository
+<https://github.com/EllisLab/CodeIgniter>`_ on GitHub.
+
+Issues are a quick way to point out a bug. If you find a bug or documentation
+error in CodeIgniter then please check a few things first:
+
+- There is not already an open Issue
+- The issue has already been fixed (check the develop branch, or look for
+  closed Issues)
+- Is it something really obvious that you fix it yourself?
+
+Reporting issues is helpful but an even better approach is to send a Pull
+Request, which is done by "Forking" the main repository and committing to your
+own copy. This will require you to use the version control system called Git.
+
+**********
+Guidelines
+**********
+
+Before we look into how, here are the guidelines. If your Pull Requests fail
+to pass these guidelines it will be declined and you will need to re-submit
+when you’ve made the changes. This might sound a bit tough, but it is required
+for us to maintain quality of the code-base.
+
+PHP Style
+=========
+
+All code must meet the `Style Guide
+<http://codeigniter.com/user_guide/general/styleguide.html>`_, which is
+essentially the `Allman indent style
+<http://en.wikipedia.org/wiki/Indent_style#Allman_style>`_, underscores and
+readable operators. This makes certain that all code is the same format as the
+existing code and means it will be as readable as possible.
+
+Documentation
+=============
+
+If you change anything that requires a change to documentation then you will
+need to add it. New classes, methods, parameters, changing default values, etc
+are all things that will require a change to documentation. The change-log
+must also be updated for every change. Also PHPDoc blocks must be maintained.
+
+Compatibility
+=============
+
+CodeIgniter is compatible with PHP 5.2.4 so all code supplied must stick to
+this requirement. If PHP 5.3 or 5.4 functions or features are used then there
+must be a fallback for PHP 5.2.4.
+
+Branching
+=========
+
+CodeIgniter uses the `Git-Flow
+<http://nvie.com/posts/a-successful-git-branching-model/>`_ branching model
+which requires all pull requests to be sent to the "develop" branch. This is
+where the next planned version will be developed. The "master" branch will
+always contain the latest stable version and is kept clean so a "hotfix" (e.g:
+an emergency security patch) can be applied to master to create a new version,
+without worrying about other features holding it up. For this reason all
+commits need to be made to "develop" and any sent to "master" will be closed
+automatically. If you have multiple changes to submit, please place all
+changes into their own branch on your fork.
+
+One thing at a time: A pull request should only contain one change. That does
+not mean only one commit, but one change - however many commits it took. The
+reason for this is that if you change X and Y but send a pull request for both
+at the same time, we might really want X but disagree with Y, meaning we
+cannot merge the request. Using the Git-Flow branching model you can create
+new branches for both of these features and send two requests.
+
+Signing
+=======
+You must sign your work, certifying that you either wrote the work or
+otherwise have the right to pass it on to an open source project. git makes
+this trivial as you merely have to use `--signoff` on your commits to your
+CodeIgniter fork.
+
+::
+
+	git commit --signoff
+
+or simply::
+
+	git commit -s
+
+This will sign your commits with the information setup in your git config, e.g.
+
+	Signed-off-by: John Q Public <john.public@example.com>
+
+If you are using Tower there is a "Sign-Off" checkbox in the commit window. You 
+could even alias git commit to use the -s flag so you don’t have to think about 
+it.
+
+By signing your work in this manner, you certify to a "Developer's Certificate 
+or Origin". The current version of this certificate is in the `DCO.txt` file
+in the root of this repository.
+
+
+************
+How-to Guide
+************
+
+There are two ways to make changes, the easy way and the hard way. Either way
+you will need to `create a GitHub account <https://github.com/signup/free>`_.
+
+Easy way GitHub allows in-line editing of files for making simple typo changes
+and quick-fixes. This is not the best way as you are unable to test the code
+works. If you do this you could be introducing syntax errors, etc, but for a
+Git-phobic user this is good for a quick-fix.
+
+Hard way The best way to contribute is to "clone" your fork of CodeIgniter to
+your development area. That sounds like some jargon, but "forking" on GitHub
+means "making a copy of that repo to your account" and "cloning" means
+"copying that code to your environment so you can work on it".
+
+#. Set up Git (Windows, Mac & Linux)
+#. Go to the CodeIgniter repo
+#. Fork it
+#. Clone your CodeIgniter repo: git@github.com:<your-name>/CodeIgniter.git
+#. Checkout the "develop" branch At this point you are ready to start making
+   changes. 
+#. Fix existing bugs on the Issue tracker after taking a look to see nobody
+   else is working on them.
+#. Commit the files
+#. Push your develop branch to your fork
+#. Send a pull request http://help.github.com/send-pull-requests/
+
+The Reactor Engineers will now be alerted about the change and at least one of
+the team will respond. If your change fails to meet the guidelines it will be
+bounced, or feedback will be provided to help you improve it.
+
+Once the Reactor Engineer handling your pull request is happy with it they
+will post it to the internal EllisLab discussion area to be double checked by
+the other Engineers and EllisLab developers. If nobody has a problem with the
+change then it will be merged into develop and will be part of the next
+release. Keeping your fork up-to-date
+
+Unlike systems like Subversion, Git can have multiple remotes. A remote is the
+name for a URL of a Git repository. By default your fork will have a remote
+named "origin" which points to your fork, but you can add another remote named
+"codeigniter" which points to git://github.com/EllisLab/CodeIgniter.git. This
+is a read-only remote but you can pull from this develop branch to update your
+own.
+
+If you are using command-line you can do the following:
+
+#. git remote add codeigniter git://github.com/EllisLab/CodeIgniter.git
+#. git pull codeigniter develop
+#. git push origin develop
+
+Now your fork is up to date. This should be done regularly, or before you send
+a pull request at least.

+All code must meet the [Style Guide](http://codeigniter.com/user_guide/general/styleguide.html), which is
+essentially the [Allman indent style](http://en.wikipedia.org/wiki/Indent_style#Allman_style), underscores and readable operators. This makes certain that all code is the same format as the existing code and means it will be as readable as possible.
+
+### Documentation
+
+If you change anything that requires a change to documentation then you will need to add it. New classes, methods, parameters, changing default values, etc are all things that will require a change to documentation. The change-log must also be updated for every change. Also PHPDoc blocks must be maintained.
+
+### Compatibility
+
+CodeIgniter is compatible with PHP 5.2.4 so all code supplied must stick to
+this requirement. If PHP 5.3 or 5.4 functions or features are used then there
+must be a fallback for PHP 5.2.4.
+
+### Branching
+
+CodeIgniter uses the [Git-Flow](http://nvie.com/posts/a-successful-git-branching-model/) branching model which requires all pull requests to be sent to the "develop" branch. This is
+where the next planned version will be developed. The "master" branch will always contain the latest stable version and is kept clean so a "hotfix" (e.g: an emergency security patch) can be applied to master to create a new version, without worrying about other features holding it up. For this reason all commits need to be made to "develop" and any sent to "master" will be closed automatically. If you have multiple changes to submit, please place all changes into their own branch on your fork.
+
+One thing at a time: A pull request should only contain one change. That does not mean only one commit, but one change - however many commits it took. The reason for this is that if you change X and Y but send a pull request for both at the same time, we might really want X but disagree with Y, meaning we cannot merge the request. Using the Git-Flow branching model you can create new branches for both of these features and send two requests.
+
+### Signing
+
+You must sign your work, certifying that you either wrote the work or otherwise have the right to pass it on to an open source project. git makes this trivial as you merely have to use `--signoff` on your commits to your CodeIgniter fork.
+
+`git commit --signoff`
+
+or simply
+
+`git commit -s`
+
+This will sign your commits with the information setup in your git config, e.g.
+
+`Signed-off-by: John Q Public <john.public@example.com>`
+
+If you are using [Tower](http://www.git-tower.com/) there is a "Sign-Off" checkbox in the commit window. You could even alias git commit to use the `-s` flag so you don’t have to think about it.
+
+By signing your work in this manner, you certify to a "Developer's Certificate of Origin". The current version of this certificate is in the `DCO.txt` file in the root of this repository.
+
+
+## How-to Guide
+
+There are two ways to make changes, the easy way and the hard way. Either way you will need to [create a GitHub account](https://github.com/signup/free).
+
+Easy way GitHub allows in-line editing of files for making simple typo changes and quick-fixes. This is not the best way as you are unable to test the code works. If you do this you could be introducing syntax errors, etc, but for a Git-phobic user this is good for a quick-fix.
+
+Hard way The best way to contribute is to "clone" your fork of CodeIgniter to your development area. That sounds like some jargon, but "forking" on GitHub means "making a copy of that repo to your account" and "cloning" means "copying that code to your environment so you can work on it".
+
+1. Set up Git (Windows, Mac & Linux)
+2. Go to the CodeIgniter repo
+3. Fork it
+4. Clone your CodeIgniter repo: git@github.com:<your-name>/CodeIgniter.git
+5. Checkout the "develop" branch At this point you are ready to start making changes. 
+6. Fix existing bugs on the Issue tracker after taking a look to see nobody else is working on them.
+7. Commit the files
+8. Push your develop branch to your fork
+9. Send a pull request [http://help.github.com/send-pull-requests/](http://help.github.com/send-pull-requests/)
+
+The Reactor Engineers will now be alerted about the change and at least one of the team will respond. If your change fails to meet the guidelines it will be bounced, or feedback will be provided to help you improve it.
+
+Once the Reactor Engineer handling your pull request is happy with it they will post it to the internal EllisLab discussion area to be double checked by the other Engineers and EllisLab developers. If nobody has a problem with the change then it will be merged into develop and will be part of the next release. Keeping your fork up-to-date
+
+Unlike systems like Subversion, Git can have multiple remotes. A remote is the name for a URL of a Git repository. By default your fork will have a remote named "origin" which points to your fork, but you can add another remote named "codeigniter" which points to `git://github.com/EllisLab/CodeIgniter.git`. This is a read-only remote but you can pull from this develop branch to update your own.
+
+If you are using command-line you can do the following:
+
+1. `git remote add codeigniter git://github.com/EllisLab/CodeIgniter.git`
+2. `git pull codeigniter develop`
+3. `git push origin develop`
+
+Now your fork is up to date. This should be done regularly, or before you send a pull request at least.

+### Test Environment:
+
+The test/Bootstrap.php file establishes global constants such as BASEPATH,
+APPPATH, and VIEWPATH, initializing them to point to VFS locations. The
+test case class employs vfsStream to make a clean virtual filesystem with
+the necessary paths for every individual test.
+
+Within each test case, VFS directory objects are available to use as arguments
+to the VFS convenience functions (see below):
+
+- ci_vfs_root: VFS filesystem root
+- ci_app_root: Application directory
+- ci_base_root: System directory
+- ci_view_root: Views directory
+
+Classes being instantiated for testing are read from the actual filesystem
+by the unit test autoloader, as are mockups created in tests/mocks. If you
+need access to the real system directory, the SYSTEM_PATH constant always
+points to it.
+
+Any other resources which need to be read from the path constants must be
+created or cloned within your test. Functions for doing so are outlined
+below.

+$this->db->replace()
+====================
+
+This method executes a REPLACE statement, which is basically the SQL
+standard for (optional) DELETE + INSERT, using *PRIMARY* and *UNIQUE*
+keys as the determining factor.
+In our case, it will save you from the need to implement complex
+logics with different combinations of  ``select()``, ``update()``,
+``delete()`` and ``insert()`` calls.
+
+Example::
+
+	$data = array(
+		'title' => 'My title',
+		'name'  => 'My Name',
+		'date'  => 'My date'
+	);
+
+	$this->db->replace('table', $data);
+
+	// Executes: REPLACE INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
+
+In the above example, if we assume that the *title* field is our primary
+key, then if a row containing 'My title' as the *title* value, that row
+will be deleted with our new row data replacing it.
+
+Usage of the ``set()`` method is also allowed and all fields are
+automatically escaped, just like with ``insert()``.

From 74ffd17ab06327ca62ddfe28a186cae7ba6bd459 Mon Sep 17 00:00:00 2001
From: Andrey Andreev <narf@bofh.bg>
Date: Sat, 27 Oct 2012 00:41:03 +0300
Subject: Deprecated form helper function form_prep().

This function has been broken for YEARS and it's value-caching
logic has only introduced various problems. We have html_escape()
since CI 2.1.0 which is a perfect replacement, so it should be
used instead.

Fixes #228 & #1630

Subject: Docblock improvements to the Config library and remove
 CI_Config::_assign_to_config()

Existance of _assign_to_config() is pointless as this method
consists just of a foreach calling CI_Config::set_item() and
is only called by CodeIgniter.php - moved that foreach() in
there instead.

 - Added _parse_query_string() which allows us to detect the URI path from QUERY_STRING much like it is done in _parse_request_uri().

(the above changes also allow for a simpler logic in the case where the *uri_protocol* setting is not set to 'AUTO')

 - Updated application/config/config.php with a better list of the *uri_protocol* options.
 - Added _reset_query_string() to aid in re-processing  from the QUERY_STRING (utilized in _parse_request_uri() and _parse_query_string()).

+********************
+Migration file names
+********************
+
+Each Migration is run in numeric order forward or backwards depending on the
+method taken. Two numbering styles are available:
+
+* **Sequential:** each migration is numbered in sequence, starting with **001**.
+  Each number must be three digits, and there must not be any gaps in the
+  sequence. (This was the numbering scheme prior to CodeIgniter 3.0.)
+* **Timestamp:** each migration is numbered using the timestamp when the migration
+  was created, in **YYYYMMDDHHIISS** format (e.g. **20121031100537**). This
+  helps prevent numbering conflicts when working in a team environment, and is
+  the preferred scheme in CodeIgniter 3.0 and later.
+
+The desired style may be selected using the **$config['migration_style']**
+setting in your **migration.php** config file.
+
+Regardless of which numbering style you choose to use, prefix your migration
+files with the migration number followed by an underscore and a descriptive
+name for the migration. For example:
+
+* **001_add_blog.php** (sequential numbering)

Subject: Changed URI auto-detection to try PATH_INFO first

(thanks to @sourcejedi, PR #1326)

Up until PHP 5.2.4 (which is our new lowest requirement),
there was a bug related to PATH_INFO which made REQUEST_URI
a more reliable choice. This is now no longer the case,
see https://bugs.php.net/bug.php?id=31892 for more details.

Also removed ORIG_PATH_INFO from the suggested alternatives
for uri_protocol in application/config/config.php as it will
not exist in most of PHP's recent versions and is pointless
when you can use PATH_INFO anyway.

 - Changed docs CREATE TABLE ci_sessions example to have the PRIMARY KEY of session_id, ip_address and user_agent combined.
 - Changed DB updates to add WHERE clauses for the ip_address and/or user_agent strings if sess_match_ip and/or sess_match_useragent are set to TRUE.

Subject: Removed CI_Loader::initialize() and moved its logic to the
 constructor.

That method used to be called by the CI_Controller constructor
and was required because of the possibility to instantiate the
Controller class twice due to 404_override, and so some properties
needed to be reset.

Following the last commit - this is no longer the case.

Subject: Refactored Unit_test in order to remove redundant code.

The Unit_test::run method was adding another dimension to the
Unit_test::$results array. For example:

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [test_name] => first_test
                    [test_datatype] => integer
                    [res_datatype] => integer
                    [result] => passed
                    [file] => ########################################
                    [line] => 60
                    [notes] => Im expecting this test to pass!
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [test_name] => second_test
                    [test_datatype] => integer
                    [res_datatype] => boolean
                    [result] => failed
                    [file] => #######################################
                    [line] => 65
                    [notes] => Im expecting this to fail.
                )

        )

)

The above unneeded dimension created a need to loop through an array in the
Unit_test::result method if the method was looping through all results.

It appears to break get_instance()->*_package_path*() usage which is very common.
Need to figure out how to resolve this.

From a287a34c215903d3452023d74149eb5880125715 Mon Sep 17 00:00:00 2001
From: Andrey Andreev <narf@bofh.bg>
Date: Mon, 5 Nov 2012 23:19:59 +0200
Subject: Refactored DB Forge

- PDO subdrivers are isolated from each other now.
- Added compatibility for pretty much all of the features, for every DB platform.
- Unified the way that stuff works in general.
- Fixes issue #1005.

+Using the php://input stream
+============================
+
+If you want to utilize the PUT, DELETE, PATCH or other exotic request
+methods, they can only be accessed via a special input stream, that
+can only be read once. This isn't as easy as just reading from e.g.
+the ``$_POST`` array, because it will always exist and you can try
+and access multiple variables without caring that you might only have
+one shot at all of the POST data.
+
+CodeIgniter will take care of that for you, and you can access data
+from the **php://input** stream at any time, just by calling the
+``input_stream()`` method::
+
+	$this->input->input_stream('key');
+
+Similar to the methods above, if the requested data is not found, it
+will return NULL and you can also decide whether to run the data
+through ``xss_clean()`` by passing a boolean value as the second
+parameter::
+
+	$this->input->input_stream('key', TRUE); // XSS Clean
+	$this->input->input_stream('key', FALSE); // No XSS filter

Subject: Added function_usable() to common functions

It is now used to check whether dangerous functions like eval() and exec() are available.
It appears that the Suhosin extension (which is becoming popular) terminates script
execution instead of returning e.g. FALSE when it has a function blacklisted.
function_exists() checks are insufficient and our only option is to check the ini
settings here.

Filed an issue here: https://github.com/stefanesser/suhosin/issues/18
... hopefully we'll be able to deal with this in a more elegant way in the future.

(this commit supersedes PR #1809)

Subject: Remove 'services' directive from .travis.yml

According to the Travis docs at http://about.travis-ci.org/docs/user/database-setup/,
mysql and postgre are started on boot (and therefore don't need manual a start), while
we all know that sqlite is not a service and doesn't need that either.

Subject: config->site_url() optimizations

- direct access to config array, instead of item() calls
- the string cast is just in case 'url_suffix' would be set to false or null; the function produces the same results without this cast, but it leads to a robuster code, as false and null are sanitized and skip the suffix insertion code
- altered conditional structure: if no suffix, skip the appending of an empty string to $uri

Subject: Remove CI_DB_oci8_result::data_seek()

It can only call oci_execute() in order to reset the pointer to 0,
the oci8 driver doesn't support setting the pointer.

Due to the result_object(), result_array() and custom_result_object()
calling data_seek() every time prior to fetching the result set, this
only causes the query to be executed twice. All of the three methods
now cast from existing result_object and/or result_array sets, so the
probability to ever need to really fetch the result set again is
practically zero and so this method doesn't bring any benefit.

Subject: While most of CodeIgniter supports protocol-relative URLs, a few URL
 helpers do not.

Most notably, redirect('//www.facebook.com/aaronadams') led my browser to https://aaronadams.ca/index.php/www.facebook.com/aaronadams.

In this commit, I have fixed the header() helper, along with the anchor() and anchor_popup() helpers, to be compatible with protocol-relative URLs.

From: Andrey Andreev <narf@bofh.bg>
Date: Fri, 14 Dec 2012 11:07:13 +0200
Subject: Fix issue #539

Form validation language line keys were not prefixed. They are
now prefixed with 'form_validation_' in order to avoid collisions.
The old keys will still work if a prefixed match is not found, but
are DEPRECATED and will be removed in the next major version.

Also added upgrade notes and changelog entries for the new error
message format from PR #961.

The Input doc does talk about xss filtering, but they refer you to Security for details, which is where the function is actually defined.  It gives more detail about what the function is supposed to do, and avoids some irrelevance.

It's probably not a big deal; it just looks wrong.  It _might_ have been responsible for [confusion](http://stackoverflow.com/questions/13570522/this-input-xss-cleandata-giving-fatal-error-with-codeigniter) sometimes.

+-  Fixed a bug (#419) - ``auto_link()`` now recognizes URLs that come after a word boundary.
+-  Fixed a bug (#724) - :doc:`Form Validation Library <libraries/form_validation>` rule **is_unique** didn't check if a database connection exists.
+-  Fixed a bug (#647) - :doc:`Zip Library <libraries/zip>` internal method ``_get_mod_time()`` didn't suppress possible "stat failed" errors generated by ``filemtime()``.
 -  Fixed a bug (#608) - Fixes an issue with the Image_lib class not clearing properties completely.
 -  Fixed a bug (#157, #174) - the Image_lib clear() function now resets all variables to their default values.
 -  Fixed a bug where using $this->dbforge->create_table() with PostgreSQL database could lead to fetching whole table.

Subject: Fixed normalization of headers under Apache

The existing header normalization routine converts headers provided by Apache (that is, with `-` in the name instead of `_`)
to all lowercase, with the exception of the first character.  This is different from the expected result, wherein each word
of the header is capitalized.  For example, `CONTENT-LENGTH` would normalize to `Content-length` instead of the expected
`Content-Length`.  The reason for this is that the existing code is only converting underscores to spaces, and leaving hyphens
untouched.  The fix is to replace hyphens with spaces as well before passing the result through `ucwords()`.

That fix is included here.

Subject: Slight performance improvement by moving some class property
 initialization to the class property declarations rather than setting them in
 the constructor. Subclasses can always override in their own constructor if
 they wish to. Is there a reason why it was done the way it was done? A policy
 that I am not aware of?

From: Daniel Hunsaker <danhunsaker@gmail.com>
Date: Thu, 24 Jan 2013 17:09:10 -0700
Subject: Updated all cases of exit() to return a valid code

Specific codes are as follows, but can easily be changed if a different order/breakdown makes more sense:

- 0: Success; everything executed as planned
- 1: Configuration Error; something is wrong with/in the configuration file(s)
- 2: Class Not Found; what it says
- 3: Driver Method Unsupported; the method you're trying to use on a Driver doesn't exist
- 4: File Not Found; 404 error
- 5: Database Error; something is broken in the database somewhere
- 6: Invalid Input; the user attempted to submit a request with invlaid characters in 1+ key names
7 through 26 are reserved for future use
- 27: Generic Error; generated by show_error() when the status code is >= 100
28 through 127 are errors generated by user applications, normally by using show_error() with a status code below 100
128 through 254 should not be used by applications, as they are reserved by system-level functions
- 255: PHP Fatal Error; automatically generated by PHP for fatal errors, and therefore not allowed for our use

Status codes below 100 are shifted up by 28 to place them in the user error range.  It may make more sense to have these codes
left alone and instead shift the CI errors into the 101 through 127 space, but that's not what I opted for here.

It would probably also be a good idea to replace the hard-coded numbers with constants or some such, but I was in a bit of a
hurry when I made these changes, so I didn't look around for the best place to do this.  With proper guidance, I could
easily amend this commit with another that uses such constant values.

Subject: Fix auto_link() for the Nth time

 - anchor() is for local links and breaks ones that don't have a protocol prefix
 - Allow :// links (no actual protocol specified)
 - Further simplified the URL regular expression

Subject: Upload library, clean_file_name function: Fix xss bug.

For example: If you clear this string "%%3f3f" according to the $bad array will fail. The result will be "%3f"
Because str_replace() replaces left to right.

+Step 9: Update your librararies' file names
+*******************************************
+
+CodeIgniter 3.0 only allows library file names to be named in a *ucfirst* manner
+(meaning that the first letter of the class name must be a capital). For example,
+if you have the following library file:
+
+	application/libraries/mylibrary.php
+
+... then you'll have to rename it to:
+
+	application/libraries/Mylibrary.php
+
+The same goes for driver libraries and extensions and/or overrides of CodeIgniter's
+own libraries and core classes.
+
+	application/libraries/MY_email.php
+	application/core/MY_log.php
+
+The above files should respectively be renamed to the following:

From: Andrey Andreev <narf@bofh.bg>
Date: Tue, 29 Jan 2013 15:05:02 +0200
Subject: Replace is_file() with the faster file_exists() (where it makes
 sense)

Also:
 - Implemented caching of configuration arrays for smileys, foreign characters and doctypes.
 - Implemented cascading-style loading of configuration files (except for library configs, DB and constants.php).

Subject: Update system/core/Log.php
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Updated Log.php so that a developer can extend it and change the log file extension.

It makes sense to default to .php when logs are in the public web folder.  It would be nice if a developer moves the log file path we have the option to use a standard extension like .log

If using nginx instead of apache by default nginx will not populate the $_SERVER['HTTPS'] value.  This change allows falling back to checking the port number of the request to determine if your on SSL or not.

The other option is adding the following to your nginx config.

fastcgi_param HTTPS on; #some php apps require this to detent https

GNU recomendations:http://www.gnu.org/software/libc/manual/html_node/Exit-Status.html
Bash scripting:http://tldp.org/LDP/abs/html/exitcodes.html

The GNU recommendations stem from and expand upon the standard C/C++ library (stdlibc)
definitions, while also suggesting some best-practice conventions which happen to prevent
exit status code collisions with bash, and probably other shells.

The re-allocated codes are now mapped to constant values, set in *application/config/constants.php*,
and used throughout the CodeIgniter core.  They would additionally be used in *index.php*,
but the constants file hasn't been loaded at that point, so the integer values are used
instead, and a comment follows each such use with amplifying information on why that
particular value was selected.

Finally, the errors documentation has been updated accordingly.

-Database Table Names
-====================
-
-Any tables that your add-on might use must use the 'exp\_' prefix,
-followed by a prefix uniquely identifying you as the developer or
-company, and then a short descriptive table name. You do not need to be
-concerned about the database prefix being used on the user's
-installation, as CodeIgniter's database class will automatically convert
-'exp\_' to what is actually being used.
-
-**INCORRECT**::
-
-	email_addresses		// missing both prefixes
-	pre_email_addresses	// missing exp_ prefix
-	exp_email_addresses	// missing unique prefix
-
-**CORRECT**::
-
-	exp_pre_email_addresses
+CodeIgniter requires a minimum PHP version of 5.2.4. Your code must either
+be compatible with this minimum requirement, provide a suitable fallback,
+or be an optional feature that dies quietly without affecting a user's
+application.
 
-.. note:: Be mindful that MySQL has a limit of 64 characters for table
-	names. This should not be an issue as table names that would exceed this
-	would likely have unreasonable names. For instance, the following table
-	name exceeds this limitation by one character. Silly, no?
-	**exp_pre_email_addresses_of_registered_users_in_seattle_washington**
+Additionally, do not use PHP functions that require non-default libraries
+to be installed unless your code contains an alternative method when the
+function is not available.
 
 One File per Class
 ==================
 
-Use separate files for each class your add-on uses, unless the classes
-are *closely related*. An example of CodeIgniter files that contains
-multiple classes is the Database class file, which contains both the DB
-class and the DB_Cache class, and the Magpie plugin, which contains
-both the Magpie and Snoopy classes.

-=============

-As you might guess, since there's a straight relationship between
-URI segments and the controller/method pair that's being called,
-those two determining segments must represent a valid class and
-method name.
-You may however also use dashes in the class/method-representing

+**************************************
+Step 2: Update your classes file names
+**************************************
+
+Starting with CodeIgniter 3.0, all class filenames (libraries, drivers, controllers
+and models) must be named in a Ucfirst-like manner or in other words - they must
+start with a capital letter.
+
+For example, if you have the following library file:
+
+	application/libraries/mylibrary.php
+
+... then you'll have to rename it to:
+
+	application/libraries/Mylibrary.php
+
+The same goes for driver libraries and extensions and/or overrides of CodeIgniter's
+own libraries and core classes.
+
+	application/libraries/MY_email.php
+	application/core/MY_log.php
+
+The above files should respectively be renamed to the following:
+
+	application/libraries/MY_Email.php
+	application/core/MY_Log.php
+
+Controllers:
+
+	application/controllers/welcome.php	->	application/controllers/Welcome.php
+
+Models:
+
+	application/models/misc_model.php	->	application/models/Misc_model.php
+
+Please note that this DOES NOT affect directories, configuration files, views,
+helpers, hooks and anything else - it is only applied to classes.
+
+You must now follow just one simple rule - class names in Ucfirst and everything else
+in lowercase.

-if you have the following library file:
-
-	application/libraries/mylibrary.php
-
-... then you'll have to rename it to:
-
-	application/libraries/Mylibrary.php
-
-The same goes for driver libraries and extensions and/or overrides of CodeIgniter's
-own libraries and core classes.
-
-	application/libraries/MY_email.php
-	application/core/MY_Log.php
-
-The above files should respectively be renamed to the following:
-
-	application/libraries/MY_Email.php
-	application/core/MY_Log.php
-

Subject: config->item() now returns NULL instead of FALSE when the required
 item doesn't exist.

Uniformization with other functions. This also brings the ability to properly use booleans in configuration.

Subject: Cache Driver - Backup Never Loaded The condition that checks to see
 if the backup driver input is valid was prefixing the input with "cache_".
 Since the valid driver values don't have this prefix, the condition was
 always returning FALSE and the backup drivers were never being loaded. I've
 removed the prefix in the condition and added a debug log message for when
 the backup driver is used.

+Overriding Word Wrapping
+========================
 
-$this->email->from()
---------------------
+If you have word wrapping enabled (recommended to comply with RFC 822)
+and you have a very long link in your email it can get wrapped too,
+causing it to become un-clickable by the person receiving it.
+CodeIgniter lets you manually override word wrapping within part of your
+message like this::
 
-Sets the email address and name of the person sending the email::
+	The text of your email that
+	gets wrapped normally.
 
-	$this->email->from('you@example.com', 'Your Name');
+	{unwrap}http://example.com/a_long_link_that_should_not_be_wrapped.html{/unwrap}
 
-You can also set a Return-Path, to help redirect undelivered mail::
+	More text that will be
+	wrapped normally.
 
-	$this->email->from('you@example.com', 'Your Name', 'returned_emails@example.com');
-	
-.. note:: Return-Path can't be used if you've configured
-	'smtp' as your protocol.
 
-$this->email->reply_to()
-------------------------
+Place the item you do not want word-wrapped between: {unwrap} {/unwrap}
 
-Sets the reply-to address. If the information is not provided the
-information in the "from" method is used. Example::
+***************
+Class Reference
+***************
 
-	$this->email->reply_to('you@example.com', 'Your Name');
+.. class:: CI_Email
 
-$this->email->to()
-------------------
+	.. method:: from($from[, $name = ''[, $return_path = NULL]])
 
-Sets the email address(s) of the recipient(s). Can be a single email, a
-comma-delimited list or an array::
+		:param string $from: "From" email address
+		:param string $name: "From" display name
+		:param string $return_path: optional email address to redirect undelivered email
+		:returns: CI_Email object for method chaining
 
-	$this->email->to('someone@example.com');
+		Sets the email address and name of the person sending the email::
 
-::
+			$this->email->from('you@example.com', 'Your Name');
 
-	$this->email->to('one@example.com, two@example.com, three@example.com');
+		You can also set a Return-Path, to help redirect undelivered mail::
 
-::
+			$this->email->from('you@example.com', 'Your Name', 'returned_emails@example.com');
 
-	$list = array('one@example.com', 'two@example.com', 'three@example.com');
+		.. note:: Return-Path can't be used if you've configured 'smtp' as
+			your protocol.
 
-	$this->email->to($list);
 
-$this->email->cc()
-------------------
+	.. method:: reply_to($replyto[, $name = ''])
 
-Sets the CC email address(s). Just like the "to", can be a single email,
-a comma-delimited list or an array.
+		:param string $replyto: email address for replies
+		:param string $name: display name for reply email address
+		:returns: CI_Email object for method chaining
 
-$this->email->bcc()
--------------------
+		Sets the reply-to address. If the information is not provided the
+		information in the :meth:from method is used. Example::
 
-Sets the BCC email address(s). Just like the "to", can be a single
-email, a comma-delimited list or an array.
+			$this->email->reply_to('you@example.com', 'Your Name');
 
-$this->email->subject()
------------------------
 
-Sets the email subject::
+	.. method:: to($to)
 
-	$this->email->subject('This is my subject');
+		:param mixed $to: comma delimited string or array of email addresses
+		:returns: CI_Email object for method chaining
 
-$this->email->message()
------------------------
+		Sets the email address(s) of the recipient(s). Can be a single email
+		, a comma-delimited list or an array::
 
-Sets the email message body::
+			$this->email->to('someone@example.com');
 
-	$this->email->message('This is my message');
+		::
 
-$this->email->set_alt_message()
--------------------------------

+		::
 
-	$this->email->set_alt_message('This is the alternative message');
+			$list = array('one@example.com', 'two@example.com', 'three@example.com');
 
-This is an optional message string which can be used if you send HTML
-formatted email. It lets you specify an alternative message with no HTML
-formatting which is added to the header string for people who do not
-accept HTML email. If you do not set your own message CodeIgniter will
-extract the message from your HTML email and strip the tags.
+			$this->email->to($list);
 
-$this->email->set_header()
---------------------------
 
-Appends additional headers to the e-mail::
+	.. method:: cc($cc)
 
-	$this->email->set_header('Header1', 'Value1');
-	$this->email->set_header('Header2', 'Value2');
+		:param mixed $cc: comma delimited string or array of email addresses
+		:returns: CI_Email object for method chaining
 
-$this->email->clear()
----------------------
+		Sets the CC email address(s). Just like the "to", can be a single
+		email, a comma-delimited list or an array.
 
-Initializes all the email variables to an empty state. This method is
-intended for use if you run the email sending method in a loop,
-permitting the data to be reset between cycles.
 
-::
+	.. method:: bcc($bcc, $limit = '')
 
-	foreach ($list as $name => $address)
-	{
-		$this->email->clear();
+		:param mixed $bcc: comma delimited string or array of email addresses
+		:param int $limit: Maximum number of emails to send per batch
+		:returns: CI_Email object for method chaining
 
-		$this->email->to($address);
-		$this->email->from('your@example.com');
-		$this->email->subject('Here is your info '.$name);
-		$this->email->message('Hi '.$name.' Here is the info you requested.');
-		$this->email->send();
-	}
+		Sets the BCC email address(s). Just like the "to", can be a single
+		email, a comma-delimited list or an array.
 
-If you set the parameter to TRUE any attachments will be cleared as
-well::
+		If ``$limit`` is set, "batch mode" will be enabled, which will send
+		the emails to batches, with each batch not exceeding the specified
+		``$limit``.
 
-	$this->email->clear(TRUE);
 
-$this->email->send()
---------------------
+	.. method:: subject($subject)
 
-The Email sending method. Returns boolean TRUE or FALSE based on
-success or failure, enabling it to be used conditionally::
+		:param string $subject: email subject line
+		:returns: CI_Email object for method chaining
 
-	if ( ! $this->email->send())
-	{
-		// Generate error
-	}
+		Sets the email subject::
 
-This method will automatically clear all parameters if the request was
-successful. To stop this behaviour pass FALSE::
+			$this->email->subject('This is my subject');
 
- 	if ($this->email->send(FALSE))
- 	{
- 		// Parameters won't be cleared
- 	}
 
-.. note:: In order to use the ``print_debugger()`` method, you need
-	to avoid clearing the email parameters.
+	.. method:: message($body)
 
-$this->email->attach()
-----------------------
+		:param string $body: email body
+		:returns: CI_Email object for method chaining
 
-Enables you to send an attachment. Put the file path/name in the first
-parameter. Note: Use a file path, not a URL. For multiple attachments
-use the method multiple times. For example::
+		Sets the email message body::
 
-	$this->email->attach('/path/to/photo1.jpg');
-	$this->email->attach('/path/to/photo2.jpg');
-	$this->email->attach('/path/to/photo3.jpg');
+			$this->email->message('This is my message');
 
-To use the default disposition (attachment), leave the second parameter blank,
-otherwise use a custom disposition::
 
-	$this->email->attach('image.jpg', 'inline');
+	.. method:: set_alt_message([$str = ''])
 
-If you'd like to use a custom file name, you can use the third paramater::
+		:param string $str: alternate email body
+		:returns: CI_Email object for method chaining
 
-	$this->email->attach('filename.pdf', 'attachment', 'report.pdf');
+		Sets the alternative email message body::
 
-If you need to use a buffer string instead of a real - physical - file you can
-use the first parameter as buffer, the third parameter as file name and the fourth
-parameter as mime-type::
+			$this->email->set_alt_message('This is the alternative message');
 
-	$this->email->attach($buffer, 'attachment', 'report.pdf', 'application/pdf');
+		This is an optional message string which can be used if you send
+		HTML formatted email. It lets you specify an alternative message
+		with no HTML formatting which is added to the header string for
+		people who do not accept HTML email. If you do not set your own
+		message CodeIgniter will extract the message from your HTML email
+		and strip the tags.
 
-$this->email->print_debugger()
-------------------------------
 
-Returns a string containing any server messages, the email headers, and

-	$this->email->print_debugger(array('headers'));
 
-.. note:: By default, all of the raw data will be printed.
+	.. method:: clear([$clear_attachments = FALSE])
 
-Overriding Word Wrapping
-========================
+		:param bool $clear_attachments: whether or not to clear attachments
 
-If you have word wrapping enabled (recommended to comply with RFC 822)
-and you have a very long link in your email it can get wrapped too,
-causing it to become un-clickable by the person receiving it.
-CodeIgniter lets you manually override word wrapping within part of your
-message like this::
+		Initializes all the email variables to an empty state. This method
+		is intended for use if you run the email sending method in a loop,
+		permitting the data to be reset between cycles.
 
-	The text of your email that
-	gets wrapped normally.
+		::
 
-	{unwrap}http://example.com/a_long_link_that_should_not_be_wrapped.html{/unwrap}
+			foreach ($list as $name => $address)
+			{
+				$this->email->clear();
 
-	More text that will be
-	wrapped normally.
-	
+				$this->email->to($address);
+				$this->email->from('your@example.com');
+				$this->email->subject('Here is your info '.$name);
+				$this->email->message('Hi '.$name.' Here is the info you requested.');
+				$this->email->send();
+			}
+
+		If you set the parameter to TRUE any attachments will be cleared as
+		well::
+
+			$this->email->clear(TRUE);
+
+
+	.. method:: send([$auto_clear = TRUE])
+
+		:param bool $auto_clear: Whether to :meth:clear automatically
+		:returns: bool
+
+		The Email sending method. Returns boolean TRUE or FALSE based on
+		success or failure, enabling it to be used conditionally::
+
+			if ( ! $this->email->send())
+			{
+				// Generate error
+			}
+
+		This method will automatically clear all parameters if the request was
+		successful. To stop this behaviour pass FALSE::
+
+		 	if ($this->email->send(FALSE))
+		 	{
+		 		// Parameters won't be cleared
+		 	}
+
+		.. note:: In order to use the ``print_debugger()`` method, you need
+			to avoid clearing the email parameters.
+
+
+	.. method:: attach($filename[, $disposition = ''[, $newname = NULL[, $mime = '']]])
+
+		:param string $filename: name of the file
+		:param string $disposition: 'disposition' of the attachment. Most
+			email clients make their own decision regardless of the MIME
+			specification used here. https://www.iana.org/assignments/cont-disp/cont-disp.xhtml
+		:param string $newname: custom name to use for the file in the email
+		:param string $mime: MIME type to use (useful for buffered data)
+		:returns: CI_Email object for method chaining
+
+		Enables you to send an attachment. Put the file path/name in the first
+		parameter. Note: Use a file path, not a URL. For multiple attachments
+		use the method multiple times. For example::
+
+			$this->email->attach('/path/to/photo1.jpg');
+			$this->email->attach('/path/to/photo2.jpg');
+			$this->email->attach('/path/to/photo3.jpg');
+
+		To use the default disposition (attachment), leave the second parameter blank,
+		otherwise use a custom disposition::
+
+			$this->email->attach('image.jpg', 'inline');
+
+		If you'd like to use a custom file name, you can use the third paramater::
+
+			$this->email->attach('filename.pdf', 'attachment', 'report.pdf');
+
+		If you need to use a buffer string instead of a real - physical - file you can
+		use the first parameter as buffer, the third parameter as file name and the fourth
+		parameter as mime-type::
+
+			$this->email->attach($buffer, 'attachment', 'report.pdf', 'application/pdf');
+
+
+	.. method:: print_debugger([$include = array('headers', 'subject', 'body')])
+
+		:param array $include: Which parts of the message to print out
+		:returns: string
+
+		Returns a string containing any server messages, the email headers, and
+		the email messsage. Useful for debugging.
+
+		You can optionally specify which parts of the message should be printed.
+		Valid options are: **headers**, **subject**, **body**.
+
+		Example::
+
+			// You need to pass FALSE while sending in order for the email data
+			// to not be cleared - if that happens, print_debugger() would have
+			// nothing to output.
+			$this->email->send(FALSE);
+
+			// Will only print the email headers, excluding the message subject and body
+			$this->email->print_debugger(array('headers'));
 
-Place the item you do not want word-wrapped between: {unwrap} {/unwrap}

Subject: Add a changelog entry for PR #2590 and further optimize log_message()

CI_Log::write_log() already checks the log threshold, so there's no point in doing it in log_message() as well.

strlen() doesn't return the actual length for unicode strings. For example strlen('سلام') returns 8, but length of سلام is 4. strlen(utf8_decode('سلام')) returns correct value 4.

-=======================
+	.. method:: read_dir($path[, $preserve_filepath = TRUE[, $root_path = NULL]])
 
-Permits you to compress a folder (and its contents) that already exists
-somewhere on your server. Supply a file path to the directory and the

-files contained within the supplied path will be encoded, as will any

-By default the Zip archive will place all directories listed in the
-first parameter inside the zip. If you want the tree preceding the
-target folder to be ignored you can pass FALSE (boolean) in the second
-parameter. Example::
+			// Download the file to your desktop. Name it "my_backup.zip"

-	$path = '/path/to/your/directory/';
+		By default the Zip archive will place all directories listed in the first parameter inside the zip.

-sub-folders stored correctly inside that, but will not include the
-folders /path/to/your.
+			$this->zip->read_dir($path, FALSE);
 
-$this->zip->archive()
-=====================
+		This will create a ZIP with a directory named "directory" inside, then all sub-directories stored correctly inside that, but will not include the
+		*/path/to/your* part of the path.
 
-Writes the Zip-encoded file to a directory on your server. Submit a
-valid server path ending in the file name. Make sure the directory is
-writable (666 or 777 is usually OK). Example::
+	.. method:: archive($filepath)
 
-	$this->zip->archive('/path/to/folder/myarchive.zip'); // Creates a file named myarchive.zip
+		:param string $filepath: path to target zip archive
+		:returns: bool
 
-$this->zip->download()
-======================
+		Writes the Zip-encoded file to a directory on your server. Submit a valid server path ending in the file name.
+		Make sure the directory is writable (660 or 666 is usually OK). Example::
 
-Causes the Zip file to be downloaded from your server. The function must
-be passed the name you would like the zip file called. Example::
+			$this->zip->archive('/path/to/folder/myarchive.zip'); // Creates a file named myarchive.zip
 
-	$this->zip->download('latest_stuff.zip'); // File will be named "latest_stuff.zip"
+	.. method:: download($filename = 'backup.zip')

-	this function since it sends various server headers that cause the
-	download to happen and the file to be treated as binary.
+		:param string $filename: the archive file name
+		:returns: void
 
-$this->zip->get_zip()
-======================
+		Causes the Zip file to be downloaded from your server. You must pass the name you would like the zip file called. Example::
 
-Returns the Zip-compressed file data. Generally you will not need this
-function unless you want to do something unique with the data. Example::
+			$this->zip->download('latest_stuff.zip'); // File will be named "latest_stuff.zip"
 
-	$name = 'my_bio.txt';

+	.. method:: get_zip()
 
-	$zip_file = $this->zip->get_zip();
+		:returns: string
 
-$this->zip->clear_data()
-=========================
+		Returns the Zip-compressed file data. Generally you will not need this method unless you want to do something unique with the data. Example::
 
-The Zip class caches your zip data so that it doesn't need to recompile
-the Zip archive for each function you use above. If, however, you need
-to create multiple Zips, each with different data, you can clear the
-cache between calls. Example::

--  Surrounds paragraphs within <p></p> (looks for double line breaks to
-   identify paragraphs).
--  Single line breaks are converted to <br />, except those that appear
-   within <pre> tags.
--  Block level elements, like <div> tags, are not wrapped within
-   paragraphs, but their contained text is if it contains paragraphs.
--  Quotes are converted to correctly facing curly quote entities, except
-   those that appear within tags.
--  Apostrophes are converted to curly apostrophe entities.
--  Double dashes (either like -- this or like--this) are converted to
-   em—dashes.
--  Three consecutive periods either preceding or following a word are
-   converted to ellipsis…
--  Double spaces following sentences are converted to non-breaking
-   spaces to mimic double spacing.
+.. class:: CI_Typography
 
-Usage example::
+	.. attribute:: $protect_braced_quotes = FALSE
 
-	$string = $this->typography->auto_typography($string);
+		When using the Typography library in conjunction with the :doc:`Template Parser library <../parser>`
+		it can often be desirable to protect single and double quotes within curly braces.
+		To enable this, set the ``protect_braced_quotes`` class property to TRUE.
 
-Parameters
-----------
+		Usage example::
 
-There is one optional parameters that determines whether the parser
-should reduce more then two consecutive line breaks down to two. Use
-boolean TRUE or FALSE.
+			$this->load->library('typography');
+			$this->typography->protect_braced_quotes = TRUE;
 
-By default the parser does not reduce line breaks. In other words, if no
-parameters are submitted, it is the same as doing this::
+	.. method auto_typography($str[, $reduce_linebreaks = FALSE])
 
-	$string = $this->typography->auto_typography($string, FALSE);
+		:param string $str: input string
+		:param bool $reduce_linebreaks: whether to reduce consequitive linebreaks
+		:returns: string
 
-.. note:: Typographic formatting can be processor intensive,
-	particularly if you have a lot of content being formatted. If you choose
-	to use this function you may want to consider :doc:`caching <../general/caching>`
-	your pages.

+		 -  Three consecutive periods either preceding or following a word are converted to ellipsis (…).
+		 -  Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.
 
-This function is similar to the auto_typography function above, except
-that it only does character conversion:

-Usage example::
+		There is one optional parameter that determines whether the parser should reduce more then two consecutive line breaks down to two.
+		Pass boolean TRUE to enable reducing line breaks::

Subject: Removed extra from $name, since it does not follow the format of
 other form_ helpers. Form helpers use $extra as a string. On the form_input
 for example, the $extra is a string but placing extra in the first parameter
 results in an attribute on the resulting element called 'extra', whereas the
 drop down it does not. $extra is now passed along as works just as all other
 form_ methods do.

       -  Changed ``site_url()`` method  to accept an array as well.
       -  Removed internal method ``_assign_to_config()`` and moved its implementation to *CodeIgniter.php* instead.
       -  ``item()`` now returns NULL instead of FALSE when the required config item doesn't exist.
+      -  Added an optional second parameter to both ``base_url()`` and ``site_url()`` that allows enforcing of a protocol different than the one in the *base_url* configuration setting.

 Redis Caching
 =============
 
+Redis is an in-memory key-value store which can operate in LRU cache mode. 
+To use it, you need Redis server and any Redis PHP extension, e.g. this one
+`https://github.com/nicolasff/phpredis <https://github.com/nicolasff/phpredis>`_.
+
+Config options to connect to redis server must be stored in the application/config/redis.php file.
+Available options are::
+	
+	$config['socket_type'] = 'tcp'; //`tcp` or `unix`
+	$config['socket'] = '/var/run/redis.sock'; // in case of `unix` socket type
+	$config['host'] = '127.0.0.1';
+	$config['password'] = NULL;
+	$config['port'] = 6379;
+	$config['timeout'] = 0;
+
 All of the methods listed above can be accessed without passing a
 specific adapter to the driver loader as follows::
 
 	$this->load->driver('cache');
 	$this->cache->redis->save('foo', 'bar', 10);
 
-.. important:: Redis may require one or more of the following options:
-	**host**, **post**, **timeout**, **password**.
-
-The Redis PHP extension repository is located at
-`https://github.com/nicolasff/phpredis <https://github.com/nicolasff/phpredis>`_.
+For more information on Redis, please see
+`http://redis.io <http://redis.io>`_.

 ===========
 
 This is a caching backend that will always 'miss.' It stores no data,
 but lets you keep your caching code in place in environments that don't
-support your chosen cache.

Subject: Enable HTTP Verb in Routing

Using array for HTTP Verb

e.g:
$route['(:any)']['POST'] = "controller/post_method";
$route['path']['GET'] = "controller/path_get_method";
$route['path']['(:any)'] = "controller/path_any_method";

Using (:any) or not will make same result
e.g: $route['path']['(:any)'] == $route['path']

So it won't break existing route

+Using HTTP Verb in Routes
+=========================
+
+If you prefer you can use HTTP Verb (or method) to define your routing rules.
+This is particularly useful when building RESTful application. You can use standard HTTP
+Verb (GET, PUT, POST, DELETE) or custom HTTP Verb (e.g: PURGE). HTTP Verb rule is case 
+insensitive. All you need to do is add array index using HTTP Verb rule. Example::
+
+	$route['products']['put'] = 'product/insert';
+
+In the above example, a PUT request to URI "products" would call the "product" controller
+class and "insert" method
+
+::
+
+	$route['products/(:num)']['DELETE'] = 'product/delete/$1';
+
+A DELETE request to URL with "products" as first segment and a number in the second will be
+remapped to the "product" class and "delete" method passing in the match as a variable to
+the method.
+
+::
+
+	$route['products/([a-z]+)/(\d+)']['get'] = 'product/$1/$2';
+
+A GET request to a URI similar to products/shirts/123 would call the "product" controller
+class and "shirt" method with number as method parameter
+
+Using HTTP Verb is optional, so if you want any HTTP Verb to be handled in one rule
+You could just write your routing rule without HTTP Verb. Example::
+
+	$route['product'] = 'product';
+
+This way, all incoming request using any HTTP method containing the word "product"
+in the first segment will be remapped to "product" class
+

-Using HTTP Verb in Routes
-=========================
+Using HTTP verbs in routes
+==========================
 
-If you prefer you can use HTTP Verb (or method) to define your routing rules.
-This is particularly useful when building RESTful application. You can use standard HTTP
-Verb (GET, PUT, POST, DELETE) or custom HTTP Verb (e.g: PURGE). HTTP Verb rule is case 
-insensitive. All you need to do is add array index using HTTP Verb rule. Example::
+It is possible to use HTTP verbs (request method) to define your routing rules.
+This is particularly useful when building RESTful applications. You can use standard HTTP
+verbs (GET, PUT, POST, DELETE, PATCH) or a custom one such (e.g. PURGE). HTTP verb rules
+are case-insensitive. All you need to do is to add the verb as an array key to your route.
+Example::
 
 	$route['products']['put'] = 'product/insert';
 
-In the above example, a PUT request to URI "products" would call the "product" controller
-class and "insert" method
+In the above example, a PUT request to URI "products" would call the ``Product::insert()``
+controller method.
 
 ::
 
 	$route['products/(:num)']['DELETE'] = 'product/delete/$1';
 
-A DELETE request to URL with "products" as first segment and a number in the second will be
-remapped to the "product" class and "delete" method passing in the match as a variable to
-the method.
-
-::
-
-	$route['products/([a-z]+)/(\d+)']['get'] = 'product/$1/$2';
-
-A GET request to a URI similar to products/shirts/123 would call the "product" controller
-class and "shirt" method with number as method parameter
-
-Using HTTP Verb is optional, so if you want any HTTP Verb to be handled in one rule
-You could just write your routing rule without HTTP Verb. Example::
-
-	$route['product'] = 'product';
+A DELETE request to URL with "products" as first the segment and a number in the second will be
+mapped to the ``Product::delete()`` method, passing the numeric value as the first parameter.
 
-This way, all incoming request using any HTTP method containing the word "product"
-in the first segment will be remapped to "product" class
+Using HTTP verbs is of course, optional.

-Step 8: Move your error templates directory
-*******************************************
+************************************
+Step 8: Replace your error templates
+************************************
 
-In version 3.0.0, the errors folder has been moved from _application/errors* to _application/views/errors*.
+In CodeIgniter 3.0, the error templates are now considered as views and have been moved to the
+_application/views/errors* directory.
+
+Furthermore, we've added support for CLI error templates in plain-text format that unlike HTML,
+is suitable for the command line. This of course requires another level of separation.
+
+It is safe to move your old templates from _application/errors* to _application/views/errors/html*,
+but you'll have to copy the new _application/views/errors/cli* directory from the CodeIgniter archive.

Subject: Remove _serialize() and _unserialize() methods

Since removing the unneeded manual escaping code, there is no-longer any reason
to have the serialization functions abstracted. This also allows us to only
suppress errors when unserializing cookie data, and only trim when we are
unserializing database data (see commit 6b8312).

+		:returns: string
 
-Note that data will only be retrievable from this function if it has
-been previously sent to the output class by one of the CodeIgniter
-functions like $this->load->view().
+		Returns the requested HTTP header value, or NULL if the requested header is not set.

-	$this->output->append_output($data);
+		.. note:: Raw headers sent via PHP's native ``header()`` function are also detected.
 
-$this->output->set_header();
-=============================

+The URI Class provides methods that help you retrieve information from
 your URI strings. If you use URI routing, you can also retrieve
 information about the re-routed segments.
 
 .. note:: This class is initialized automatically by the system so there
 	is no need to do it manually.
 
-$this->uri->segment(n)
-======================
+***************
+Class Reference
+***************
 
-Permits you to retrieve a specific segment. Where n is the segment
-number you wish to retrieve. Segments are numbered from left to right.
-For example, if your full URL is this::
+.. class:: CI_URI
 
-	http://example.com/index.php/news/local/metro/crime_is_up
+	.. method:: segment($n[, $no_result = NULL])
 
-The segment numbers would be this:
+		:param int $n: Segment index number
+		:param mixed $no_result: What to return if the searched segment is not found
+		:returns: mixed
 
-#. news
-#. local
-#. metro
-#. crime_is_up
+		Permits you to retrieve a specific segment. Where n is the segment
+		number you wish to retrieve. Segments are numbered from left to right.
+		For example, if your full URL is this::
 
-By default the function returns NULL if the segment does not
-exist. There is an optional second parameter that permits you to set
-your own default value if the segment is missing. For example, this
-would tell the function to return the number zero in the event of
-failure::
+			http://example.com/index.php/news/local/metro/crime_is_up
 
-	$product_id = $this->uri->segment(3, 0);
+		The segment numbers would be this:
 
-It helps avoid having to write code like this::
+		#. news
+		#. local
+		#. metro
+		#. crime_is_up
 
-	if ($this->uri->segment(3) === FALSE)
-	{
-	    $product_id = 0;
-	}
-	else
-	{
-	    $product_id = $this->uri->segment(3);
-	}
+		The optional second parameter defaults to NULL and allows you to set the return value
+		of this method when the requested URI segment is missing.
+		For example, this would tell the method to return the number zero in the event of failure::
 
-$this->uri->rsegment(n)
-=======================
+			$product_id = $this->uri->segment(3, 0);
 
-This function is identical to the previous one, except that it lets you
-retrieve a specific segment from your re-routed URI in the event you are
-using CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
+		It helps avoid having to write code like this::
 
-$this->uri->slash_segment(n)
-=============================
+			if ($this->uri->segment(3) === FALSE)
+			{
+				$product_id = 0;
+			}
+			else
+			{
+				$product_id = $this->uri->segment(3);
+			}
 
-This function is almost identical to $this->uri->segment(), except it
-adds a trailing and/or leading slash based on the second parameter. If

+		#. /segment

+		:param string $where: Where to add the slash ('trailing' or 'leading')
+		:returns: string
 
-The first parameter of the function lets you set an offset. By default

+		be set to that name, with a value of NULL.
 
-	$array = array('product' => 'shoes', 'size' => 'large', 'color' => 'red');
+		Lastly, if a corresponding value is not found for a given key (if there

-****************
-Helper Reference
-****************
-
-The following helper functions are available for use in the view files
-containing your forms. Note that these are procedural functions, so they
-**do not** require you to prepend them with $this->form_validation.
-
-form_error()
-============
-
-Shows an individual error message associated with the field name
-supplied to the function. Example::
+	.. method:: error_string([$prefix = ''[, $suffix = '']])
 
-	<?php echo form_error('username'); ?>
-
-The error delimiters can be optionally specified. See the
-:ref:`changing-delimiters` section above.
-
-validation_errors()
-===================
-
-Shows all error messages as a string: Example::
-
-	<?php echo validation_errors(); ?>
-
-The error delimiters can be optionally specified. See the
-:ref:`changing-delimiters` section above.
-
-set_value()
-===========
+		:param string $prefix: Error message prefix
+		:param string $suffix: Error message suffix
+		:returns: string
 
-Permits you to set the value of an input form or textarea. You must
-supply the field name via the first parameter of the function. The
-second (optional) parameter allows you to set a default value for the
-form. Example::
+		Returns all error messages (as returned from error_array()) formatted as a
+		string and separated by a newline character.
 
-	<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" />
+	.. method:: error($field[, $prefix = ''[, $suffix = '']])
 
-The above form will show "0" when loaded for the first time.
+		:param string $field: Field name
+		:param string $prefix: Optional prefix
+		:param string $suffix: Optional suffix
+		:returns: string
 
-set_select()
-============
+		Returns the error message for a specific field, optionally adding a
+		prefix and/or suffix to it (usually HTML tags).
 
-If you use a <select> menu, this function permits you to display the
-menu item that was selected. The first parameter must contain the name
-of the select menu, the second parameter must contain the value of each
-item, and the third (optional) parameter lets you set an item as the
-default (use boolean TRUE/FALSE).
+	.. method:: has_rule($field)
 
-Example::
+		:param string $field: Field name
+		:returns: bool
 
-	<select name="myselect">
-	<option value="one" <?php echo set_select('myselect', 'one', TRUE); ?> >One</option>
-	<option value="two" <?php echo set_select('myselect', 'two'); ?> >Two</option>
-	<option value="three" <?php echo set_select('myselect', 'three'); ?> >Three</option>
-	</select>
+		Checks to see if there is a rule set for the specified field.
 
-set_checkbox()
-==============
-
-Permits you to display a checkbox in the state it was submitted. The
-first parameter must contain the name of the checkbox, the second
-parameter must contain its value, and the third (optional) parameter
-lets you set an item as the default (use boolean TRUE/FALSE). Example::
-
-	<input type="checkbox" name="mycheck[]" value="1" <?php echo set_checkbox('mycheck[]', '1'); ?> />
-	<input type="checkbox" name="mycheck[]" value="2" <?php echo set_checkbox('mycheck[]', '2'); ?> />
+.. _helper-functions:
 
-set_radio()
-===========
+****************
+Helper Reference
+****************
 
-Permits you to display radio buttons in the state they were submitted.
-This function is identical to the **set_checkbox()** function above.
+Please refer to the :doc:`Form Helper <../helpers/form_helper>` manual for
+the following functions:
 
-::
+-  :func:`form_error()`
+-  :func:`validation_errors()`
+-  :func:`set_value()`
+-  :func:`set_select()`
+-  :func:`set_checkbox()`
+-  :func:`set_radio()`
 
-	<input type="radio" name="myradio" value="1" <?php echo set_radio('myradio', '1', TRUE); ?> />
-	<input type="radio" name="myradio" value="2" <?php echo set_radio('myradio', '2'); ?> />
+Note that these are procedural functions, so they **do not** require you
+to prepend them with ``$this->form_validation``.

+======================
 
-For example, if you would like to send email with CodeIgniter, the first
-step is to load the email class within your controller::
+An application package allows for the easy distribution of complete sets
+of resources in a single directory, complete with its own libraries,
+models, helpers, config, and language files. It is recommended that
+these packages be placed in the application/third_party directory. Below
+is a sample map of an package directory.
 
-	$this->load->library('email');
+The following is an example of a directory for an application package
+named "Foo Bar".
 
-Once loaded, the library will be ready for use, using
-$this->email->*some_method*().

-Library files can be stored in subdirectories within the main

+	/application/third_party/foo_bar
 
-	libraries/flavors/Chocolate.php
+	config/

+	language/
+	libraries/
+	models/
 
-You will load it using::
+Whatever the purpose of the "Foo Bar" application package, it has its
+own config files, helpers, language files, libraries, and models. To use
+these resources in your controllers, you first need to tell the Loader
+that you are going to be loading resources from a package, by adding the
+package path via the ``add_package_path()`` method.
 
-	$this->load->library('flavors/chocolate');
+Package view files
+------------------
 
-You may nest the file in as many subdirectories as you want.
+By Default, package view files paths are set when ``add_package_path()``
+is called. View paths are looped through, and once a match is
+encountered that view is loaded.
 
-Additionally, multiple libraries can be loaded at the same time by
-passing an array of libraries to the load method.
+In this instance, it is possible for view naming collisions within
+packages to occur, and possibly the incorrect package being loaded. To
+ensure against this, set an optional second parameter of FALSE when
+calling ``add_package_path()``.

-$this->load->view('file_name', $data, TRUE/FALSE)
-=================================================
+		This method is used to load driver libraries, acts very much like the
+		``library()`` method.
 
-This method is used to load your View files. If you haven't read the
-:doc:`Views <../general/views>` section of the user guide it is
-recommended that you do since it shows you how this method is
-typically used.
+		As an example, if you would like to use sessions with CodeIgniter, the first
+		step is to load the session driver within your controller::
 
-The first parameter is required. It is the name of the view file you
-would like to load.
+			$this->load->driver('session');
 
-.. note:: The .php file extension does not need to be specified unless
-	you use something other than .php.
+		Once loaded, the library will be ready for use, using ``$this->session``.
 
-The second **optional** parameter can take an associative array or an
-object as input, which it runs through the PHP
-`extract() <http://www.php.net/extract>`_ function to convert to variables
-that can be used in your view files. Again, read the
-:doc:`Views <../general/views>` page to learn how this might be useful.
+		Driver files must be stored in a subdirectory within the main
+		"libraries" directory, or within your personal *application/libraries*
+		directory. The subdirectory must match the parent class name. Read the
+		:doc:`Drivers <../general/drivers>` description for details.
 
-The third **optional** parameter lets you change the behavior of the
-method so that it returns data as a string rather than sending it to
-your browser. This can be useful if you want to process the data in some
-way. If you set the parameter to true (boolean) it will return data. The
-default behavior is false, which sends it to your browser. Remember to
-assign it to a variable if you want the data returned::
+		Additionally, multiple driver libraries can be loaded at the same time by
+		passing an array of drivers to the load method.
+		::
 
-	$string = $this->load->view('myfile', '', true);
+			$this->load->driver(array('session', 'cache'));
 
-$this->load->model('model_name');
-==================================
+		Setting options
+		---------------
 
-::
+		The second (optional) parameter allows you to optionally pass
+		configuration settings. You will typically pass these as an array::
 
-	$this->load->model('model_name');
+			$config = array(
+				'sess_driver' => 'cookie',
+				'sess_encrypt_cookie'  => true,
+				'encryption_key' => 'mysecretkey'
+			);
 
+			$this->load->driver('session', $config);
 
-If your model is located in a subdirectory, include the relative path
-from your models directory. For example, if you have a model located at
-application/models/blog/queries.php you'll load it using::
+		Config options can usually also be set via a config file. Each library
+		is explained in detail in its own page, so please read the information
+		regarding each one you would like to use.
 
-	$this->load->model('blog/queries');
+		Assigning a Driver to a different object name
+		---------------------------------------------
 
-If you would like your model assigned to a different object name you can
-specify it via the second parameter of the loading method::
+		If the third (optional) parameter is blank, the library will be assigned
+		to an object with the same name as the parent class. For example, if
+		the library is named Session, it will be assigned to a variable named
+		``$this->session``.
 
-	$this->load->model('model_name', 'fubar');
-	$this->fubar->method();
+		If you prefer to set your own class names you can pass its value to the
+		third parameter::
 
-$this->load->database('options', TRUE/FALSE)
-============================================

-$this->load->vars($array)
-=========================
+	.. method:: view($view[, $vars = array()[, return = FALSE]])
 
-This method takes an associative array as input and generates
-variables using the PHP `extract <http://www.php.net/extract>`_
-method. This method produces the same result as using the second
-parameter of the ``$this->load->view()`` method above. The reason you
-might want to use this method independently is if you would like to
-set some global variables in the constructor of your controller and have
-them become available in any view file loaded from any method. You can
-have multiple calls to this method. The data get cached and merged
-into one array for conversion to variables.

+		:param array $vars: An associative array of variables
+		:param bool $return: Whether to return the loaded view
+		:returns: mixed
 
-$this->load->get_var($key)
-==========================
+		This method is used to load your View files. If you haven't read the
+		:doc:`Views <../general/views>` section of the user guide it is
+		recommended that you do since it shows you how this method is
+		typically used.
 
-This method checks the associative array of variables available to
-your views. This is useful if for any reason a var is set in a library
-or another controller method using ``$this->load->vars()``.
+		The first parameter is required. It is the name of the view file you
+		would like to load.
 
-$this->load->get_vars()
-=======================
+		.. note:: The .php file extension does not need to be specified unless
+			you use something other than .php.
 
-This method retrieves all variables available to your views.
+		The second **optional** parameter can take an associative array or an
+		object as input, which it runs through the PHP
+		`extract() <http://www.php.net/extract>`_ function to convert to variables
+		that can be used in your view files. Again, read the
+		:doc:`Views <../general/views>` page to learn how this might be useful.
 
-$this->load->helper('file_name')
-================================
+		The third **optional** parameter lets you change the behavior of the
+		method so that it returns data as a string rather than sending it to
+		your browser. This can be useful if you want to process the data in some
+		way. If you set the parameter to TRUE (boolean) it will return data. The
+		default behavior is FALSE, which sends it to your browser. Remember to
+		assign it to a variable if you want the data returned::
 
-This method loads helper files, where file_name is the name of the
-file, without the _helper.php extension.
+			$string = $this->load->view('myfile', '', TRUE);
 
-$this->load->file('filepath/filename', TRUE/FALSE)
-==================================================
+	.. method:: vars($vars[, $val = ''])
 
-This is a generic file loading method. Supply the filepath and name in
-the first parameter and it will open and read the file. By default the
-data is sent to your browser, just like a View file, but if you set the
-second parameter to true (boolean) it will instead return the data as a
-string.
+		:param mixed $vars: An array of variables or a single variable name
+		:param mixed $val: Optional variable value
+		:returns: void
 
-$this->load->language('file_name')
-==================================
+		This method takes an associative array as input and generates
+		variables using the PHP `extract() <http://www.php.net/extract>`_
+		function. This method produces the same result as using the second
+		parameter of the ``$this->load->view()`` method above. The reason you

-Application "Packages"
-======================
+	.. method:: get_vars()
 
-An application package allows for the easy distribution of complete sets
-of resources in a single directory, complete with its own libraries,
-models, helpers, config, and language files. It is recommended that
-these packages be placed in the application/third_party directory. Below
-is a sample map of an package directory

-Sample Package "Foo Bar" Directory Map
-======================================
+		This method retrieves all variables available to your views.
 
-The following is an example of a directory for an application package
-named "Foo Bar".
+	.. method:: model($model[, $name = ''[, $db_conn = FALSE]])

+		::
 
-	config/
-	helpers/
-	language/
-	libraries/
-	models/
+			$this->load->model('model_name');
 
-Whatever the purpose of the "Foo Bar" application package, it has its
-own config files, helpers, language files, libraries, and models. To use
-these resources in your controllers, you first need to tell the Loader
-that you are going to be loading resources from a package, by adding the
-package path.
 
-$this->load->add_package_path()
----------------------------------
+		If your model is located in a subdirectory, include the relative path
+		from your models directory. For example, if you have a model located at
+		*application/models/blog/queries.php* you'll load it using::
 
-Adding a package path instructs the Loader class to prepend a given path
-for subsequent requests for resources. As an example, the "Foo Bar"
-application package above has a library named Foo_bar.php. In our
-controller, we'd do the following::
+			$this->load->model('blog/queries');
 
-	$this->load->add_package_path(APPPATH.'third_party/foo_bar/');
-	$this->load->library('foo_bar');
+		If you would like your model assigned to a different object name you can
+		specify it via the second parameter of the loading method::
 
-$this->load->remove_package_path()
-------------------------------------
+			$this->load->model('model_name', 'fubar');
+			$this->fubar->method();
 
-When your controller is finished using resources from an application
-package, and particularly if you have other application packages you
-want to work with, you may wish to remove the package path so the Loader
-no longer looks in that directory for resources. To remove the last path
-added, simply call the method with no parameters.
+	.. method:: database([$params = ''[, $return = FALSE[, $query_builder = NULL]]])
 
-$this->load->remove_package_path()
-------------------------------------
+		:param mixed $params: Database group name or configuration options
+		:param bool $return: Whether to return the loaded database object
+		:param bool $query_builder: Whether to load the Query Builder
+		:returns: mixed
 
-Or to remove a specific package path, specify the same path previously
-given to add_package_path() for a package.::

-Package view files
-------------------

-$this->image_lib->resize()
-===========================
-
-The image resizing function lets you resize the original image, create a
-copy (with or without resizing), or create a thumbnail image.
-
-For practical purposes there is no difference between creating a copy
-and creating a thumbnail except a thumb will have the thumbnail marker
-as part of the name (ie, mypic_thumb.jpg).
-
-All preferences listed in the table above are available for this
-function except these three: rotation_angle, x_axis, and y_axis.
-
-Creating a Thumbnail
---------------------
-
-The resizing function will create a thumbnail file (and preserve the
-original) if you set this preference to TRUE::
-
-	$config['create_thumb'] = TRUE;
-
-This single preference determines whether a thumbnail is created or not.
-
-Creating a Copy
----------------
-
-The resizing function will create a copy of the image file (and preserve
-the original) if you set a path and/or a new filename using this
-preference::
-
-	$config['new_image'] = '/path/to/new_image.jpg';
-
-Notes regarding this preference:
-
--  If only the new image name is specified it will be placed in the same
-   folder as the original
--  If only the path is specified, the new image will be placed in the
-   destination with the same name as the original.
--  If both the path and image name are specified it will placed in its
-   own destination and given the new name.
-
-Resizing the Original Image
----------------------------
-
-If neither of the two preferences listed above (create_thumb, and
-new_image) are used, the resizing function will instead target the
-original image for processing.
-
-$this->image_lib->crop()
-=========================
-
-The cropping function works nearly identically to the resizing function
-except it requires that you set preferences for the X and Y axis (in
-pixels) specifying where to crop, like this::
-
-	$config['x_axis'] = '100';
-	$config['y_axis'] = '40';
-
-All preferences listed in the table above are available for this
-function except these: rotation_angle, create_thumb, new_image.
-
-Here's an example showing how you might crop an image::
-
-	$config['image_library'] = 'imagemagick';
-	$config['library_path'] = '/usr/X11R6/bin/';
-	$config['source_image']	= '/path/to/image/mypic.jpg';
-	$config['x_axis'] = '100';
-	$config['y_axis'] = '60';
-
-	$this->image_lib->initialize($config); 
-
-	if ( ! $this->image_lib->crop())
-	{
-	    echo $this->image_lib->display_errors();
-	}
-
-.. note:: Without a visual interface it is difficult to crop images, so this
-	function is not very useful unless you intend to build such an
-	interface. That's exactly what we did using for the photo gallery module
-	in ExpressionEngine, the CMS we develop. We added a JavaScript UI that
-	lets the cropping area be selected.
-
-$this->image_lib->rotate()
-===========================
-
-The image rotation function requires that the angle of rotation be set
-via its preference::
-
-	$config['rotation_angle'] = '90';
-
-There are 5 rotation options:
-
-#. 90 - rotates counter-clockwise by 90 degrees.
-#. 180 - rotates counter-clockwise by 180 degrees.
-#. 270 - rotates counter-clockwise by 270 degrees.
-#. hor - flips the image horizontally.
-#. vrt - flips the image vertically.
-
-Here's an example showing how you might rotate an image::
-
-	$config['image_library'] = 'netpbm';
-	$config['library_path'] = '/usr/bin/';
-	$config['source_image']	= '/path/to/image/mypic.jpg';
-	$config['rotation_angle'] = 'hor';
-
-	$this->image_lib->initialize($config); 
-
-	if ( ! $this->image_lib->rotate())
-	{
-	    echo $this->image_lib->display_errors();
-	}
-

-image. You will want to call this if you are processing images in a
-loop.

+		the original) if you set a path and/or a new filename using this
+		preference::
+
+			$config['new_image'] = '/path/to/new_image.jpg';
+
+		Notes regarding this preference:
+
+		-  If only the new image name is specified it will be placed in the same
+		   folder as the original
+		-  If only the path is specified, the new image will be placed in the
+		   destination with the same name as the original.
+		-  If both the path and image name are specified it will placed in its
+		   own destination and given the new name.
+
+		Resizing the Original Image
+		---------------------------
+
+		If neither of the two preferences listed above (create_thumb, and
+		new_image) are used, the resizing method will instead target the
+		original image for processing.
+
+	.. method:: crop()
+
+		:returns: bool
+
+		The cropping method works nearly identically to the resizing function
+		except it requires that you set preferences for the X and Y axis (in
+		pixels) specifying where to crop, like this::
+
+			$config['x_axis'] = '100';
+			$config['y_axis'] = '40';
+
+		All preferences listed in the :ref:`processing-preferences` table are available for this
+		method except these: *rotation_angle*, *create_thumb* and *new_image*.
+
+		Here's an example showing how you might crop an image::
+
+			$config['image_library'] = 'imagemagick';
+			$config['library_path'] = '/usr/X11R6/bin/';
+			$config['source_image']	= '/path/to/image/mypic.jpg';
+			$config['x_axis'] = '100';
+			$config['y_axis'] = '60';
+
+			$this->image_lib->initialize($config); 
+
+			if ( ! $this->image_lib->crop())
+			{
+				echo $this->image_lib->display_errors();
+			}
+
+		.. note:: Without a visual interface it is difficult to crop images, so this
+			method is not very useful unless you intend to build such an
+			interface. That's exactly what we did using for the photo gallery module
+			in ExpressionEngine, the CMS we develop. We added a JavaScript UI that
+			lets the cropping area be selected.
+
+	.. method:: rotate()
+
+		:returns: bool
+
+		The image rotation method requires that the angle of rotation be set
+		via its preference::
+
+			$config['rotation_angle'] = '90';
+
+		There are 5 rotation options:
+
+		#. 90 - rotates counter-clockwise by 90 degrees.
+		#. 180 - rotates counter-clockwise by 180 degrees.
+		#. 270 - rotates counter-clockwise by 270 degrees.
+		#. hor - flips the image horizontally.
+		#. vrt - flips the image vertically.
+
+		Here's an example showing how you might rotate an image::
+
+			$config['image_library'] = 'netpbm';
+			$config['library_path'] = '/usr/bin/';
+			$config['source_image']	= '/path/to/image/mypic.jpg';
+			$config['rotation_angle'] = 'hor';
+
+			$this->image_lib->initialize($config); 
+
+			if ( ! $this->image_lib->rotate())
+			{
+				echo $this->image_lib->display_errors();
+			}
+
+	.. method:: watermark()
+
+		:returns: bool
+
+		Creates a watermark over an image, please refer to the :ref:`watermarking`
+		section for more info.		
+
+	.. method:: clear()
+
+		:returns: void
+
+		The clear method resets all of the values used when processing an
+		image. You will want to call this if you are processing images in a
+		loop.
+
+		::
+
+			$this->image_lib->clear();
+
+	.. method:: display_errors([$open = '<p>[, $close = '</p>']])
+
+		:param string $open: Error message opening tag
+		:param string $close: Error message closing tag
+		:returns: string
+
+		Returns all detected errors formatted as a string.
+		::

Subject: Fix #2143

When trying to load rules from a configuration file, the Form validation library matched against
ruri_string() as opposed to 'controller/method' like described in the manual. Since ruri_string()
also makes sense, now both are being checked with ruri_string() having a higher precedence.

Subject: Fix #148

CI_Input::_clean_input_data() assumed that all input data is URL-encoded while sanitizing it.
However, PHP already performs URL-decoding on it, so this is either redudant or overly
intrusive as it resulted in many, many reports of data containing '%' followed by 1 numeric
characters being essentially destroyed.

Supersedes PR #1229

Subject: Fix #346

When ['global_xss_filtering'] was turned on, the , ,  &
superglobals were automatically overwritten. This resulted in one of the following problems:

 - xss_clean() being called twice
 - Inability to retrieve the original (not filtered) value

XSS filtering is now only applied on demand by the Input class, and the default value for
the  parameter in CI_Input methods is changed to NULL. Unless a boolean value is
passed to them, whether XSS filtering is applied depends on the ['global_xss_filtering']
value.

+Step 11: Usage of XSS filtering
+*******************************
+
+Many functions in CodeIgniter allow you to use its XSS filtering feature

+parameter used to be boolean FALSE, but it is now changed to NULL and it
+will be dynamically determined by your ``$config['global_xss_filtering']``
+value.

Subject: Deprecate the 'mysql', 'sqlite', 'mssql' and 'pdo/dblib' drivers

The 'mysql' PHP extension is notorious for it's problems and is deprecated as of PHP 5.5.

The other ones are dropped from PHP 5.3.

 :doc:`Smiley Helper <../helpers/smiley_helper>` function ``js_insert_smiley()`` has been deprecated

+Database drivers 'mysql', 'sqlite', 'mssql', 'pdo/dblib'
+========================================================
+
+The **mysql** driver utilizes the old 'mysql' PHP extension, known for its aging code base and
+many low-level problems. The extension is deprecated as of PHP 5.5 and CodeIgniter deprecates
+it in version 3.0, switching the default configured MySQL driver to **mysqli**.
+
+Please use either the 'mysqli' or 'pdo/mysql' drivers for MySQL. The old 'mysql' driver will be
+removed at some point in the future.
+
+The **sqlite**, **mssql** and **pdo/dblib** (also known as pdo/mssql or pdo/sybase) drivers
+all depend on PHP extensions that for different reasons no longer exist since PHP 5.3.
+
+Therefore we are now deprecating these drivers as we will have to remove them in one of the next
+CodeIgniter versions. You should use the more advanced, **sqlite3**, **sqlsrv** or **pdo/sqlsrv**
+drivers respectively.
+
+.. note:: These drivers are still available, but you're strongly encouraged to switch to other ones
+	sooner rather than later.

Subject: Remove preg_quote() call from CI_User_agent::_set_browser() and add
 another pattern for Opera

Input comes from a configuration file that is barely touched by anyone
and the default values only contain letters, so it is safe to not
quote them.

This enables us to add a more advanced pattern in config/user_agents.php
for Opera 10+, which ... quote:

  Opera/9.80 is hard coded at the beginning of the user agent string because of broken browser sniffing scripts which detect 'Opera/10' and above as Opera 1.

(reference: http://my.opera.com/community/openweb/idopera/)

Instead, latests versions of Opera append ' Version/<version number>'
to the end of the user agent string.

Fixes issue #555 (incorrect browser detection for Opera)

 -  Fixed a bug (#346) - with ``$config['global_xss_filtering']`` turned on, the ``$_GET``, ``$_POST``, ``$_COOKIE`` and ``$_SERVER`` superglobals were overwritten during initialization time, resulting in XSS filtering being either performed twice or there was no possible way to get the original data, even though options for this do exist.

Subject: Don't throw in mock autoloader

This behavior doesn't appear to be used at all.

This fixes HHVM compatibility: HHVM optimizes class_exists() to a
dedicated bytecode - as it's not a function call, it doesn't show up
in the backtrace. 100% of the tests pass with this change.

Also removed an unnecessary log level check that caused an extra space to be inserted
for the INFO level. (proposed in PR #2821)

 - Initialize and cache the value in the class constructor instead of searching for it every time
 - Removed the preg_quote() call from _filter_uri() to allow more fine-tuning from configuration
 - Renamed _filter_uri() to filter_uri() - it was public anyway and using it cannot break anything

Subject: Fix #2822: Incorrect usage of fwrite()

We only used to check (and not always) if the return value of fwrite() is boolean FALSE,
while it is possible that the otherwise returned bytecount is less than the length of
data that we're trying to write. This allowed incomplete writes over network streams
and possibly a few other edge cases.

Subject: URI Routing overhaul

 - Allow multiple levels of controller directories (supersedes PRs #390, #2439)
 - Add support for per-directory 'defaul_controller' and '404_override' (resolves issue #2611; supersedes PR #939)
 - Fixed a bug where default_controller was called instead of triggering 404 if the current route is inside a directory
 - Removed a few calls from CI_Router to CI_URI that made a necessity for otherwise internal CI_URI methods to be public:

    - Removed CI_URI::_fetch_uri_string() and moved its logic into CI_URI::__construct()
    - Removed CI_URI::_remove_url_suffix, CI_URI::_explode_segments() and moved their logic into CI_URI::_set_uri_string()
    - Removed CI_URI::_reindex_segments() altogether ( doesn't need further manipulation, while  is
      public anyway and can be properly (and more effectively) replaced on the spot)

From a9938a09e8214b778b8ab11f60501661bb2ac623 Mon Sep 17 00:00:00 2001
From: Andrey Andreev <narf@devilix.net>
Date: Fri, 17 Jan 2014 14:55:56 +0200
Subject: Minor changes related to CI_User_agent

Fixed a bug where both accept_charset() and accept_lang() improperly parsed headers
if they contained spaces between data separators (which is valid).

Also made is_referral() testable by replacing its static cache var with a class
property and added some more unit tests for the library as a whole.

+################
+Encryption Class
+################
+
+The Encryption Class provides two-way data encryption. It uses a scheme
+that either compiles the message using a randomly hashed bitwise XOR
+encoding scheme, or is encrypted using the Mcrypt library. If Mcrypt is
+not available on your server the encoded message will still provide a
+reasonable degree of security for encrypted sessions or other such
+"light" purposes. If Mcrypt is available, you'll be provided with a high
+degree of security appropriate for storage.
+
+Setting your Key
+================
+
+A *key* is a piece of information that controls the cryptographic
+process and permits an encrypted string to be decoded. In fact, the key
+you chose will provide the **only** means to decode data that was
+encrypted with that key, so not only must you choose the key carefully,
+you must never change it if you intend use it for persistent data.
+
+It goes without saying that you should guard your key carefully. Should
+someone gain access to your key, the data will be easily decoded. If
+your server is not totally under your control it's impossible to ensure
+key security so you may want to think carefully before using it for
+anything that requires high security, like storing credit card numbers.
+
+To take maximum advantage of the encryption algorithm, your key should
+be 32 characters in length (256 bits). The key should be as random a
+string as you can concoct, with numbers and uppercase and lowercase
+letters. Your key should **not** be a simple text string. In order to be
+cryptographically secure it needs to be as random as possible.
+
+Your key can be either stored in your **application/config/config.php**, or
+you can design your own storage mechanism and pass the key dynamically
+when encoding/decoding.
+
+To save your key to your **application/config/config.php**, open the file
+and set::
+
+	$config['encryption_key'] = "YOUR KEY";
+
+Message Length
+==============
+
+It's important for you to know that the encoded messages the encryption
+function generates will be approximately 2.6 times longer than the
+original message. For example, if you encrypt the string "my super
+secret data", which is 21 characters in length, you'll end up with an
+encoded string that is roughly 55 characters (we say "roughly" because
+the encoded string length increments in 64 bit clusters, so it's not
+exactly linear). Keep this information in mind when selecting your data
+storage mechanism. Cookies, for example, can only hold 4K of
+information.
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Encryption class is
+initialized in your controller using the **$this->load->library** function::
+
+	$this->load->library('encrypt');
+
+Once loaded, the Encrypt library object will be available using:
+$this->encrypt
+
+$this->encrypt->encode()
+========================
+
+Performs the data encryption and returns it as a string. Example::
+
+	$msg = 'My secret message';
+
+	$encrypted_string = $this->encrypt->encode($msg);
+	
+
+You can optionally pass your encryption key via the second parameter if
+you don't want to use the one in your config file::
+
+	$msg = 'My secret message';
+	$key = 'super-secret-key';
+
+	$encrypted_string = $this->encrypt->encode($msg, $key);
+
+$this->encrypt->decode()
+========================
+
+Decrypts an encoded string. Example::
+
+	$encrypted_string = 'APANtByIGI1BpVXZTJgcsAG8GZl8pdwwa84';
+
+	$plaintext_string = $this->encrypt->decode($encrypted_string);
+
+You can optionally pass your encryption key via the second parameter if
+you don't want to use the one in your config file::
+
+	$msg = 'My secret message';
+	$key = 'super-secret-key';
+
+	$encrypted_string = $this->encrypt->decode($msg, $key);
+
+$this->encrypt->set_cipher();
+==============================
+
+Permits you to set an Mcrypt cipher. By default it uses
+**MCRYPT_RIJNDAEL_256**. Example::
+
+	$this->encrypt->set_cipher(MCRYPT_BLOWFISH);
+
+Please visit php.net for a list of `available
+ciphers <http://php.net/mcrypt>`_.
+
+If you'd like to manually test whether your server supports Mcrypt you
+can use::
+
+	echo ( ! function_exists('mcrypt_encrypt')) ? 'Nope' : 'Yup';
+
+$this->encrypt->set_mode();
+============================
+
+Permits you to set an Mcrypt mode. By default it uses **MCRYPT_MODE_CBC**.
+Example::
+
+	$this->encrypt->set_mode(MCRYPT_MODE_CFB);
+
+Please visit php.net for a list of `available
+modes <http://php.net/mcrypt>`_.
+
+$this->encrypt->encode_from_legacy($orig_data, $legacy_mode = MCRYPT_MODE_ECB, $key = '');
+==========================================================================================
+
+Enables you to re-encode data that was originally encrypted with
+CodeIgniter 1.x to be compatible with the Encryption library in
+CodeIgniter 2.x. It is only necessary to use this method if you have
+encrypted data stored permanently such as in a file or database and are
+on a server that supports Mcrypt. "Light" use encryption such as
+encrypted session data or transitory encrypted flashdata require no
+intervention on your part. However, existing encrypted Sessions will be
+destroyed since data encrypted prior to 2.x will not be decoded.
+
+.. important::
+	**Why only a method to re-encode the data instead of maintaining legacy
+	methods for both encoding and decoding?** The algorithms in the
+	Encryption library have improved in CodeIgniter 2.x both for performance
+	and security, and we do not wish to encourage continued use of the older
+	methods. You can of course extend the Encryption library if you wish and
+	replace the new methods with the old and retain seamless compatibility
+	with CodeIgniter 1.x encrypted data, but this a decision that a
+	developer should make cautiously and deliberately, if at all.
+
+::
+
+	$new_data = $this->encrypt->encode_from_legacy($old_encrypted_string);
+
+======================	===============	 =======================================================================
+Parameter		 Default	  Description
+======================	===============  =======================================================================
+**$orig_data**		n/a 		 The original encrypted data from CodeIgniter 1.x's Encryption library
+**$legacy_mode**	MCRYPT_MODE_ECB	 The Mcrypt mode that was used to generate the original encrypted data.

-you don't want to use the one in your config file::
-
-	$msg = 'My secret message';
-	$key = 'super-secret-key';
-
-	$encrypted_string = $this->encrypt->decode($msg, $key);
-
-$this->encrypt->set_cipher();
-==============================
-
-Permits you to set an Mcrypt cipher. By default it uses
-**MCRYPT_RIJNDAEL_256**. Example::
-
-	$this->encrypt->set_cipher(MCRYPT_BLOWFISH);
-
-Please visit php.net for a list of `available
-ciphers <http://php.net/mcrypt>`_.
-
-If you'd like to manually test whether your server supports Mcrypt you
-can use::
-
-	echo ( ! function_exists('mcrypt_encrypt')) ? 'Nope' : 'Yup';
-
-$this->encrypt->set_mode();
-============================
-
-Permits you to set an Mcrypt mode. By default it uses **MCRYPT_MODE_CBC**.
-Example::
-
-	$this->encrypt->set_mode(MCRYPT_MODE_CFB);
-
-Please visit php.net for a list of `available
-modes <http://php.net/mcrypt>`_.
-
-$this->encrypt->encode_from_legacy($orig_data, $legacy_mode = MCRYPT_MODE_ECB, $key = '');
-==========================================================================================
-
-Enables you to re-encode data that was originally encrypted with
-CodeIgniter 1.x to be compatible with the Encryption library in
-CodeIgniter 2.x. It is only necessary to use this method if you have
-encrypted data stored permanently such as in a file or database and are
-on a server that supports Mcrypt. "Light" use encryption such as
-encrypted session data or transitory encrypted flashdata require no
-intervention on your part. However, existing encrypted Sessions will be
-destroyed since data encrypted prior to 2.x will not be decoded.
-
-.. important::
-	**Why only a method to re-encode the data instead of maintaining legacy
-	methods for both encoding and decoding?** The algorithms in the
-	Encryption library have improved in CodeIgniter 2.x both for performance
-	and security, and we do not wish to encourage continued use of the older
-	methods. You can of course extend the Encryption library if you wish and
-	replace the new methods with the old and retain seamless compatibility
-	with CodeIgniter 1.x encrypted data, but this a decision that a
-	developer should make cautiously and deliberately, if at all.
-
-::
-
-	$new_data = $this->encrypt->encode_from_legacy($old_encrypted_string);
-
-======================	===============	 =======================================================================
-Parameter		 Default	  Description
-======================	===============  =======================================================================
-**$orig_data**		n/a 		 The original encrypted data from CodeIgniter 1.x's Encryption library
-**$legacy_mode**	MCRYPT_MODE_ECB	 The Mcrypt mode that was used to generate the original encrypted data.
-					 CodeIgniter 1.x's default was MCRYPT_MODE_ECB, and it will assume that
-					 to be the case unless overridden by this parameter.
-**$key**		n/a 		 The encryption key. This it typically specified in your config file as
-					 outlined above.

Subject: More CI_Encryption improvements

 - Make OpenSSL the default driver if available (because MCrypt is stupid).
 - Require MCRYPT_DEV_URANDOM for the MCrypt availability check
   (because security; also, incidentally - it's faster that way ;)).

Subject: simplify calendar library

it seemed quite strange that we ask users to pass in a template string the we parse with REGEX, to extract key/value pairs, when we can simply ask users for an array.

the class still contains default variables for each part of the template. Users can simply pass in an array (instead of a string) when they initialize, $config['template'], which overwrites default values.

this cuts down a little on file size by removing parse_template() function.
I think arrays are much more straightforward and easy to read than 'encoded' strings.
don't have to keep a running list of all template keys like in previous parse_template() function.
gets rid of $this->temp[] property and changes it to $this->template[] which is more descriptive when generating output

Subject: CI_Input tweaks

 - Make get_post(), post_get() and server()'s  parameter mandatory.
 - Change default value of  parameter to NULL for cookie(), input_stream() and _fetch_from_array()
   (for consistency with get(), post()).
 - Delegate Array-vs-single and  parameter detection to _fetch_from_array() to overall simplify the code.

Subject: CodeIgniter support some basic web security by default!
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I think its better to enable this basic security options by default.
It’s more likely that users who build a new website or application from
ground up, and use CodeIgniter can get used to this and eventually turn
this off. From a web security perspective, we can support a more secure
web, by default! Who agrees?

Logical Operators
Use of || is discouraged as its clarity on some output devices is low
(looking like the number 11 for instance). && is preferred over AND but
either are acceptable, and a space should always precede and follow !

+##################
+Encryption Library
+##################
+
+The Encryption Library provides two-way data encryption. To do so in
+a cryptographically secure way, it utilizes PHP extensions that are
+unfortunately not always available on all systems.
+You must meet one of the following dependancies in order to use this
+library:
+
+- `OpenSSL <http://php.net/openssl>`_ (and PHP 5.3.3)
+- `MCrypt <http://php.net/mcrypt>`_ (and `MCRYPT_DEV_URANDOM` availability)
+
+If neither of the above dependancies is met, we simply cannot offer
+you a good enough implementation to meet the high standards required
+for proper cryptography.
+
+.. contents::
+  :local:
+
+.. raw:: html
+
+  <div class="custom-index container"></div>
+
+****************************
+Using the Encryption Library
+****************************
+
+Initializing the Class
+======================
+
+Like most other classes in CodeIgniter, the Encryption library is
+initialized in your controller using the ``$this->load->library()``
+method::
+
+	$this->load->library('encrypt');
+
+Once loaded, the Encryption library object will be available using::
+
+	$this->encrypt
+
+Default behavior
+================
+
+By default, the Encryption Library will use the AES-128 cipher in CBC
+mode, using your configured *encryption_key* and SHA512 HMAC authentication.
+
+.. note:: AES-128 is chosen both because it is proven to be strong and
+	because of its wide availability across different cryptographic
+	software and programming languages' APIs.
+
+However, the *encryption_key* is not used as is.
+
+If you are somewhat familiar with cryptography, you should already know
+that a HMAC also requires a secret key and using the same key for both
+encryption and authentication is a bad practice.
+
+Because of that, two separate keys are derived from your already configured
+*encryption_key*: one for encryption and one for authentication. This is
+done via a technique called `HMAC-based Key Derivation Function
+<http://en.wikipedia.org/wiki/HKDF>`_ (HKDF).
+
+Setting your encryption_key
+===========================
+
+An *encryption key* is a piece of information that controls the
+cryptographic process and permits a plain-text string to be encrypted,
+and afterwards - decrypted. It is the secret "ingredient" in the whole
+process that allows you to be the only one who is able to decrypt data
+that you've decided to hide from the eyes of the public.
+After one key is used to encrypt data, that same key provides the **only**
+means to decrypt it, so not only must you chose one carefully, but you
+must not lose it or you will also use the encrypted data.
+
+It must be noted that to ensure maximum security, such key *should* not
+only be as strong as possible, but also often changed. Such behavior
+however is rarely practical or possible to implement, and that is why
+CodeIgniter gives you the ability to configure a single key that is to be
+used (almost) every time.
+
+It goes without saying that you should guard your key carefully. Should
+someone gain access to your key, the data will be easily decrypted. If
+your server is not totally under your control it's impossible to ensure
+key security so you may want to think carefully before using it for
+anything that requires high security, like storing credit card numbers.
+
+Your encryption key should be as long as the encyption algorithm in use
+allows. For AES-128, that's 128 bits or 16 bytes (charcters) long. The
+key should be as random as possible and it should **not** be a simple
+text string.
+
+You will find a table below that shows the supported key lengths of
+different ciphers.
+
+The key can be either stored in your *application/config/config.php*, or
+you can design your own storage mechanism and pass the key dynamically
+when encrypting/decrypting.
+
+To save your key to your *application/config/config.php*, open the file
+and set::
+
+	$config['encryption_key'] = 'YOUR KEY';
+
+.. _ciphers-and-modes:
+
+Supported encryption ciphers and modes
+======================================
+
+.. note:: The terms 'cipher' and 'encryption algorithm' are interchangeable.
+
+Portable ciphers
+----------------
+
+Because MCrypt and OpenSSL (also called drivers throughout this document)
+each support different sets of encryption algorithms and often implement
+them in different ways, our Encryption library is designed to use them in
+a portable fashion, or in other words - it enables you to use them
+interchangeably, at least for the ciphers supported by both drivers.
+
+It is also implemented in a way that aims to match the standard
+implementations in other programming languages and libraries.
+
+Here's a list of the so called "portable" ciphers, where
+"CodeIgniter name" is the string value that you'd have to pass to the
+Encryption library to use that cipher:
+
+======================== ================== ============================ ===============================
+Cipher name              CodeIgniter name   Key lengths (bits / bytes)   Supported modes
+======================== ================== ============================ ===============================
+AES-128 / Rijndael-128   aes-128            128 / 16                     CBC, CTR, CFB, CFB8, OFB, ECB
+AES-192                  aes-192            192 / 24                     CBC, CTR, CFB, CFB8, OFB, ECB
+AES-256                  aes-256            256 / 32                     CBC, CTR, CFB, CFB8, OFB, ECB
+DES                      des                56 / 7                       CBC, CFB, CFB8, OFB, ECB
+TripleDES                tripledes          56 / 7, 112 / 14, 168 / 21   CBC, CFB, CFB8, OFB
+Blowfish                 blowfish           128-448 / 16-56              CBC, CFB, OFB, ECB
+CAST5 / CAST-128         cast5              40-128 / 5-16                CBC, CFB, OFB, ECB
+RC4 / ARCFour            rc4                40-2048 / 5-256              Stream
+======================== ================== ============================ ===============================
+
+.. important:: Because of how MCrypt works, if you fail to provide a key
+	with the appropriate length, you might end up using a different
+	algorithm than the one configured, so be really careful with that!
+
+.. note:: In case it isn't clear from the above table, Blowfish, CAST5
+	and RC4 support variable length keys. That is, any number in the
+	shown ranges is valid, although in bit terms that only happens
+	in 8-bit increments.
+
+.. note:: Even though CAST5 supports key lengths lower than 128 bits
+	(16 bytes), in fact they will just be zero-padded to the
+	maximum length, as specified in `RFC 2144
+	<http://tools.ietf.org/rfc/rfc2144.txt>`_.
+
+.. note:: Blowfish supports key lengths as small as 32 bits (4 bytes), but
+	our tests have shown that only lengths of 128 bits (16 bytes) or
+	higher are properly supported by both MCrypt and OpenSSL. It is
+	also a bad practice to use such low-length keys anyway.
+
+Driver-specific ciphers
+-----------------------
+
+As noted above, MCrypt and OpenSSL support different sets of encryption
+ciphers. For portability reasons and because we haven't tested them
+properly, we do not advise you to use the ones that are driver-specific,
+but regardless, here's a list of most of them:

+	its name in lower-case to the Encryption library.
+
+.. note:: You've probably noticed that all AES cipers (and Rijndael-128)
+	are also listed in the portable ciphers list. This is because
+	drivers support different modes for these ciphers. Also, it is
+	important to note that AES-128 and Rijndael-128 are actually
+	the same cipher, but **only** when used with a 128-bit key.
+
+.. note:: RC2 is listed as supported by both MCrypt and OpenSSL.
+	However, both drivers implement them differently and they
+	are not portable. It is probably worth noting that we only
+	found one obscure source confirming that it is MCrypt that
+	is not properly implementing it.
+
+.. _encryption-modes:
+
+Encryption modes
+----------------
+
+Different modes of encryption have different characteristics and serve
+for different purposes. Some are stronger than others, some are faster
+and some offer extra features.
+We are not going in depth into that here, we'll leave that to the
+cryptography experts. The table below is to provide brief informational
+reference to our more experienced users. If you are a beginner, just
+stick to the CBC mode - it is widely accepted as strong and secure for
+general purposes.
+
+=========== ================== ================= ===================================================================================================================================================
+Mode name   CodeIgniter name   Driver support    Additional info
+=========== ================== ================= ===================================================================================================================================================
+CBC         cbc                MCrypt, OpenSSL   A safe default choice
+CTR         ctr                MCrypt, OpenSSL   Considered as theoretically better than CBC, but not as widely available
+CFB         cfb                MCrypt, OpenSSL   N/A
+CFB8        cfb8               MCrypt, OpenSSL   Same as CFB, but operates in 8-bit mode (not recommended).
+OFB         ofb                MCrypt, OpenSSL   N/A
+OFB8        ofb8               MCrypt            Same as OFB, but operates in 8-bit mode (not recommended).
+ECB         ecb                MCrypt, OpenSSL   Ignores IV (not recommended).
+GCM         gcm                OpenSSL           Provides authentication and therefore doesn't need a HMAC.
+XTS         xts                OpenSSL           Usually used for encrypting random access data such as RAM or hard-disk storage.
+Stream      stream             MCrypt, OpenSSL   This is not actually a mode, it just says that a stream cipher is being used. Required because of the general cipher+mode initialization process.
+=========== ================== ================= ===================================================================================================================================================
+
+Message Length
+==============
+
+It's probably important for you to know that an encrypted string is usually
+longer than the original, plain-text string (depending on the cipher).
+
+This is influenced by the cipher algorithm itself, the IV prepended to the
+cipher-text and (unless you are using GCM mode) the HMAC authentication
+message that is also prepended. Furthermore, the encrypted message is also
+Base64-encoded so that it is safe for storage and transmission, regardless
+of a possible character set in use.
+
+Keep this information in mind when selecting your data storage mechanism.
+Cookies, for example, can only hold 4K of information.
+
+.. _configuration:
+
+Configuring the library
+=======================
+
+For usability, performance, but also historical reasons tied to our old
+:doc:`Encrypt Class <encrypt>`, the Encryption library is designed to
+use repeatedly the same driver, encryption cipher, mode and key.
+
+As noted in the "Default behavior" section above, this means using an
+auto-detected driver (OpenSSL has a higher priority), the AES-128 ciper
+in CBC mode, and your ``$config['encryption_key']`` value.
+
+If you wish to change that however, you need to use the ``initialize()``
+method. It accepts an associative array of parameters, all of which are
+optional:
+
+======== ===============================================
+Option   Possible values
+======== ===============================================
+driver   'mcrypt', 'openssl'
+cipher   Cipher name (see :ref:`ciphers-and-modes`)
+mode     Encryption mode (see :ref:`encryption-modes`)
+key      Encryption key 
+======== ===============================================
+
+For example, if you were to change the encryption algorithm and
+mode to AES-256 in CTR mode, this is what you should do::
+
+	$this->encryption->initialize(
+		array(
+			'cipher' => 'aes-256',
+			'mode' => 'ctr',
+			'key' => '<a 32-character random string>'
+		)
+	);
+
+Note that we only mentioned that you want to change the ciper and mode,
+but we also included a key in the example. As previously noted, it is
+important that you choose a key with a proper size for the used algorithm.
+
+There's also the ability to change the driver, if for some reason you
+have both, but want to use MCrypt instead of OpenSSL::
+
+	// Switch to the MCrypt driver
+	$this->encryption->initialize(array('driver' => 'mcrypt'));
+
+	// Switch back to the OpenSSL driver
+	$this->encryption->initialize(array('driver' => 'openssl'));
+
+Encrypting and decrypting data
+==============================
+
+Encrypting and decrypting data with the already configured library
+settings is simple. As simple as just passing the string to the
+``encrypt()`` and/or ``decrypt()`` methods::
+
+	$plain_text = 'This is a plain-text message!';
+	$ciphertext = $this->encryption->encrypt($plain_text);
+
+	// Outputs: This is a plain-text message!
+	echo $this->encryption->decrypt($ciphertext);
+
+And that's it! The Encryption library will do everything necessary
+for the whole process to be cryptographically secure out-of-the-box.
+You don't need to worry about it.
+
+.. important:: Both methods will return FALSE in case of an error.
+	While for ``encrypt()`` this can only mean incorrect
+	configuration, you should always check the return value
+	of ``decrypt()`` in production code.
+
+How it works
+------------
+
+If you must know how the process works, here's what happens under
+the hood:
+
+- ``$this->encryption->encrypt($plain_text)``
+
+  #. Derive an encryption key and a HMAC key from your configured
+     *encryption_key* via HKDF, using the SHA-512 digest algorithm.
+
+  #. Generate a random initialization vector (IV).
+
+  #. Encrypt the data via AES-128 in CBC mode (or another previously
+     configured cipher and mode), using the above-mentioned derived
+     encryption key and IV.
+
+  #. Prepend said IV to the resulting cipher-text.
+
+  #. Base64-encode the resulting string, so that it can be safely
+     stored or transferred without worrying about character sets.
+
+  #. Create a SHA-512 HMAC authentication message using the derived
+     HMAC key to ensure data integrity and prepend it to the Base64
+     string.
+
+- ``$this->encryption->decrypt($ciphertext)``
+
+  #. Derive an encryption key and a HMAC key from your configured
+     *encryption_key* via HKDF, using the SHA-512 digest algorithm.
+     Because your configured *encryption_key* is the same, this
+     will produce the same result as in the ``encrypt()`` method
+     above - otherwise you won't be able to decrypt it.
+
+  #. Check if the string is long enough, separate the HMAC out of
+     it and validate if it is correct (this is done in a way that
+     prevents timing attacks agains it). Return FALSE if either of
+     the checks fails.
+
+  #. Base64-decode the string.
+
+  #. Separate the IV out of the cipher-text and decrypt the said
+     cipher-text using that IV and the derived encryption key.
+
+.. _custom-parameters:
+
+Using custom parameters
+-----------------------
+
+Let's say you have to interact with another system that is out
+of your control and uses another method to encrypt data. A
+method that will most certainly not match the above-described
+sequence and probably not use all of the steps either.
+
+The Encryption library allows you to change how its encryption
+and decryption processes work, so that you can easily tailor a
+custom solution for such situations.
+
+.. note:: It is possible to use the library in this way, without
+	setting an *encryption_key* in your configuration file.
+
+All you have to do is to pass an associative array with a few
+parameters to either the ``encrypt()`` or ``decrypt()`` method.
+Here's an example::
+
+	// Assume that we have $ciphertext, $key and $hmac_key
+	// from on outside source
+
+	$message = $this->encryption->decrypt(
+		$ciphertext,
+		array(
+			'cipher' => 'blowfish',
+			'mode' => 'cbc',
+			'key' => $key,
+			'hmac_digest' => 'sha256',
+			'hmac_key' => $hmac_key
+		)
+	);
+
+In the above example, we are decrypting a message that was encrypted
+using the Blowfish cipher in CBC mode and authenticated via a SHA-256
+HMAC.
+
+.. important:: Note that both 'key' and 'hmac_key' are used in this
+	example. When using custom parameters, encryption and HMAC keys
+	are not derived like the default behavior of the library is.
+
+Below is a list of the available options.
+
+However, unless you really need to and you know what you are doing,
+we advise you to not change the encryption process as this could
+impact security, so please do so with caution.
+
+============= =============== ============================= ======================================================
+Option        Default value   Mandatory / Optional          Description
+============= =============== ============================= ======================================================
+cipher        N/A             Yes                           Encryption algorithm (see :ref:`ciphers-and-modes`).
+mode          N/A             Yes                           Encryption mode (see :ref:`encryption-modes`).
+key           N/A             Yes                           Encryption key.
+iv            N/A             No                            Initialization vector (IV).
+                                                            If not provided it will be automatically generated
+                                                            during encryption and looked for during decryption.
+hmac          TRUE            No                            Whether to use a HMAC.
+                                                            Boolean. If set to FALSE, then *hmac_digest* and
+                                                            *hmac_key* will be ignored.
+hmac_digest   sha512          No                            HMAC message digest algorithm (see :ref:`digests`).
+hmac_key      N/A             Yes, unless *hmac* is FALSE   HMAC key.
+raw_data      FALSE           No                            Whether the cipher-text should be raw.
+                                                            Boolean. If set to TRUE, then Base64 encoding and
+                                                            decoding will not be performed and HMAC will not
+                                                            be a hexadecimal string.
+============= =============== ============================= ======================================================
+
+.. important:: ``encrypt()`` and ``decrypt()`` will return FALSE if
+	a mandatory parameter is not provided or if a provided
+	value is incorrect. This includes *hmac_key*, unless *hmac*
+	is set to FALSE.
+
+.. note:: If GCM mode is used, *hmac* will always be FALSE. This is
+	because GCM mode itself provides authentication.
+
+.. _digests:
+
+Supported HMAC authentication algorithms
+----------------------------------------
+
+For HMAC message authentication, the Encryption library supports
+usage of the SHA-2 family of algorithms:
+
+=========== ==================== ============================
+Algorithm   Raw length (bytes)   Hex-encoded length (bytes)
+=========== ==================== ============================
+sha512      64                   128
+sha384      48                   96
+sha256      32                   64
+sha224      28                   56
+=========== ==================== ============================
+
+The reason for not including other popular algorithms, such as
+MD5 or SHA1 is that they are no longer considered secure enough
+and as such, we don't want to encourage their usage.
+If you absolutely need to use them, it is easy to do so via PHP's
+native `hash_hmac() <http://php.net/hash_hmac()>`_ function.
+
+Stronger algorithms of course will be added in the future as they
+appear and become widely available.

Subject: Introducing compatibility layers

 - Limited support for mbstring (mb_strlen(), mb_strpos(), mb_substr() only) via iconv.
   Falls back to regular strlen(), strpos(), substr() if iconv is not available.
 - Password hashing, dependant on CRYPT_BLOWFISH (2y version, available since PHP 5.3.7) availability.

+   -  Added compatibility layers for PHP's `Multibyte string <http://php.net/mbstring>`_ (limited support) and `Password Hashing <http://php.net/password>` extensions.
    -  Removed ``CI_CORE`` boolean constant from *CodeIgniter.php* (no longer Reactor and Core versions).

    -  Added support for HTTP-Only cookies with new config option *cookie_httponly* (default FALSE).

+Compatibility Functions

+
+CodeIgniter provides a set of compatibility functions that enable

+
+Being custom implementations, these functions will also have some
+set of dependancies on their own, but are still useful if your
+PHP setup doesn't offer them natively.
+
+.. note:: Much like the `common functions <common_functions>`, the
+	compatibility functions are always available, as long as
+	their dependancies are met.

+****************
+Password Hashing
+****************
+
+This set of compatibility functions offers a "backport" of PHP's
+standard `Password Hashing extension <http://php.net/password>`_
+that is otherwise available only since PHP 5.5.
+
+Dependancies
+============
+
+- PHP 5.3.7
+- ``CRYPT_BLOWFISH`` support for ``crypt()``
+
+Constants
+=========
+
+- ``PASSWORD_BCRYPT``
+- ``PASSWORD_DEFAULT``
+
+Function reference
+==================
+
+.. function:: password_get_info($hash)
+
+	:param	string	$hash: Password hash
+	:returns:	Information about the hashed password
+	:rtype:	array
+
+	For more information, please refer to the `PHP manual for
+	password_get_info() <http://php.net/password_get_info>`_.
+
+.. function:: password_hash($password, $algo[, $options = array()])
+
+	:param	string	$password: Plain-text password
+	:param	int	$algo: Hashing algorithm
+	:param	array	$options: Hashing options
+	:returns:	Hashed password or FALSE on failure
+	:rtype:	string
+
+	For more information, please refer to the `PHP manual for
+	password_hash() <http://php.net/password_hash>`_.
+
+	.. note:: Unless you provide your own (and valid) salt, this function
+		has a further dependancy on an available CSPRNG source. Each
+		of the following would satisfy that:
+		- ``mcrypt_create_iv()`` with ``MCRYPT_DEV_URANDOM``
+		- ``openssl_random_pseudo_bytes()``
+		- /dev/arandom
+		- /dev/urandom
+
+.. function:: password_needs_rehash()
+
+	:param	string	$hash: Password hash
+	:param	int	$algo: Hashing algorithm
+	:param	array	$options: Hashing options
+	:returns:	TRUE if the hash should be rehashed to match the given algorithm and options, FALSE otherwise
+	:rtype:	bool
+
+	For more information, please refer to the `PHP manual for
+	password_needs_rehash() <http://php.net/password_needs_rehash>`_.
+
+.. function:: password_verify($password, $hash)
+
+	:param	string	$password: Plain-text password
+	:param	string	$hash: Password hash
+	:returns:	TRUE if the password matches the hash, FALSE if not
+	:rtype:	bool
+
+	For more information, please refer to the `PHP manual for
+	password_verify() <http://php.net/password_verify>`_.
+
+****************
+Multibyte String
+****************
+
+This set of compatibility functions offers limited support for PHP's
+`Multibyte String extension <http://php.net/mbstring>`_. Because of
+the limited alternative solutions, only a few functions are available.
+
+.. note:: When a character set parameter is ommited,
+	``$config['charset']`` will be used.
+
+Dependancies
+============
+
+- `iconv <http://php.net/iconv>`_ extension
+
+.. important:: This dependancy is optional and these functions will
+	always be declared. If iconv is not available, they WILL
+	fall-back to their non-mbstring versions.
+
+.. important:: Where a character set is supplied, it must be
+	supported by iconv and in a format that it recognizes.
+
+.. note:: For you own dependancy check on the actual mbstring
+	extension, use the ``MB_ENABLED`` constant.
+
+Function reference
+==================
+
+.. function:: mb_strlen($str[, $encoding = NULL])
+
+	:param	string	$str: Input string
+	:param	string	$encoding: Character set
+	:returns:	Number of characters in the input string or FALSE on failure
+	:rtype:	string
+
+	For more information, please refer to the `PHP manual for
+	mb_strlen() <http://php.net/mb_strlen>`_.
+
+.. function:: mb_strpos($haystack, $needle[, $offset = 0[, $encoding = NULL]])
+
+	:param	string	$haystack: String to search in
+	:param	string	$needle: Part of string to search for
+	:param	int	$offset: Search offset
+	:param	string	$encoding: Character set
+	:returns:	Numeric character position of where $needle was found or FALSE if not found
+	:rtype:	mixed
+
+	For more information, please refer to the `PHP manual for
+	mb_strpos() <http://php.net/mb_strpos>`_.
+
+.. function:: mb_substr($str, $start[, $length = NULL[, $encoding = NULL]])
+
+	:param	string	$str: Input string
+	:param	int	$start: Position of first character
+	:param	int	$length: Maximum number of characters
+	:param	string	$encoding: Character set
+	:returns:	Portion of $str specified by $start and $length or FALSE on failure
+	:rtype:	string
+
+	For more information, please refer to the `PHP manual for
+	mb_substr() <http://php.net/mb_substr>`_.

- Change CI_Router::__construct() to accept  as a parameter.

    -  Renamed internal method ``_escape_identifiers()`` to ``escape_identifiers()``.
    -  Updated ``escape_identifiers()`` to accept an array of fields as well as strings.
    -  MySQL and MySQLi drivers now require at least MySQL version 5.1.
+   -  Added a ``$persistent`` parameter to ``db_connect()`` and changed ``db_pconnect()`` to be an alias for ``db_connect(TRUE)``.
    -  ``db_set_charset()`` now only requires one parameter (collation was only needed due to legacy support for MySQL versions prior to 5.1).
-   -  ``db_select()`` will now always (if required by the driver) be called by ``db_connect()`` / ``db_pconnect()`` instead of only when initializing.
+   -  ``db_select()`` will now always (if required by the driver) be called by ``db_connect()`` instead of only when initializing.
    -  Replaced the ``_error_message()`` and ``_error_number()`` methods with ``error()``, which returns an array containing the last database error code and message.
    -  Improved ``version()`` implementation so that drivers that have a native function to get the version number don't have to be defined in the core ``DB_driver`` class.
    -  Added capability for packages to hold *config/database.php* config files.

+Callable: Use anything as a rule
+================================
+
+If callback rules aren't good enough for you (for example, because they are
+limited to your controller), don't get disappointed, there's one more way
+to create custom rules: anything that ``is_callable()`` would return TRUE for.
+
+Consider the following example::
+
+	$this->form_validation->set_rules(
+		'username', 'Username',
+		array(
+			'required',
+			array($this->users_model, 'valid_username')
+		)
+	);
+
+The above code would use the ``valid_username()`` method from your
+``Users_model`` object.
+
+This is just an example of course, and callbacks aren't limited to models.
+You can use any object/method that accepts the field value as its' first
+parameter. Or if you're running PHP 5.3+, you can also use an anonymous
+function:
+
+	$this->form_validation->set_rules(
+		'username', 'Username',
+		array(
+			'required',
+			function($value)
+			{
+				// Check $value and return TRUE/FALSE

Subject: Yet another method for determining "base_url"

This one is great because we don't have to deal with the special cases:
* in Windows, dirname('/foo/index.php') gives "/foo", but dirname('/index.php') gives "\" instead of "/"
* dirname() doesn't include the trailing slash, with the expection of "/" (root)

Subject: Add hash_equals() to ext/hash compat layer

Introduced in PHP 5.6 Beta 1 (unfortunately, still undocumented).
RFC: https://wiki.php.net/rfc/timing_attack

(Yes, I am aware that the RFC talks about hash_compare(), the function was later renamed in the implementation.)

 /**
  * CodeIgniter Session Class
  *
- * The user interface defined by EllisLabs, now with puggable drivers to manage different storage mechanisms.
- * By default, the cookie session driver will load, but the 'sess_driver' config/param item (see above) can be
- * used to specify the 'native' driver, or any other you might create.
- * Once loaded, this driver setup is a drop-in replacement for the former CI_Session library, taking its place as the
- * 'session' member of the global controller framework (e.g.: $CI->session or $this->session).
- * In keeping with the CI_Driver methodology, multiple drivers may be loaded, although this might be a bit confusing.
- * The CI_Session library class keeps track of the most recently loaded driver as "current" to call for driver methods.
- * Ideally, one driver is loaded and all calls go directly through the main library interface. However, any methods
- * called through the specific driver will switch the "current" driver to itself before invoking the library method
- * (which will then call back into the driver for low-level operations). So, alternation between two drivers can be
- * achieved by specifying which driver to use for each call (e.g.: $this->session->native->set_userdata('foo', 'bar');
- * $this->session->cookie->userdata('foo'); $this->session->native->unset_userdata('foo');). Notice in the previous
- * example that the _native_ userdata value 'foo' would be set to 'bar', which would NOT be returned by the call for
- * the _cookie_ userdata 'foo', nor would the _cookie_ value be unset by the call to unset the _native_ 'foo' value.

-/**
- * CI_Session_driver Class
- *
- * Extend this class to make a new CI_Session driver.
- * A CI_Session driver basically manages an array of name/value pairs with some sort of storage mechanism.
- * To make a new driver, derive from (extend) CI_Session_driver. Overload the initialize method and read or create
- * session data. Then implement a save handler to write changed data to storage (sess_save), a destroy handler
- * to remove deleted data (sess_destroy), and an access handler to expose the data (get_userdata).
- * Put your driver in the libraries/Session/drivers folder anywhere in the loader paths. This includes the
- * application directory, the system directory, or any path you add with $CI->load->add_package_path().
- * Your driver must be named CI_Session_<name>, and your filename must be Session_<name>.php,
- * preferably also capitalized. (e.g.: CI_Session_foo in libraries/Session/drivers/Session_foo.php)
- * Then specify the driver by setting 'sess_driver' in your config file or as a parameter when loading the CI_Session
- * object. (e.g.: $config['sess_driver'] = 'foo'; OR $CI->load->driver('session', array('sess_driver' => 'foo')); )
- * Already provided are the Native driver, which manages the native PHP $_SESSION array, and
- * the Cookie driver, which manages the data in a browser cookie, with optional extra storage in a database table.

 Encrypt Class
 #############
 
-The Encrypt Class provides two-way data encryption. It uses a scheme
-that either compiles the message using a randomly hashed bitwise XOR
-encoding scheme, or is encrypted using the Mcrypt library. If Mcrypt is
-not available on your server the encoded message will still provide a
-reasonable degree of security for encrypted sessions or other such
-"light" purposes. If Mcrypt is available, you'll be provided with a high
-degree of security appropriate for storage.
+The Encrypt Class provides two-way data encryption. It encrypted using
+the Mcrypt PHP extension, which is required for the Encrypt Class to run.
 
 .. important:: This library has been DEPRECATED and is only kept for
 	backwards compatibility. Please use the new :doc:`Encryption Library

 you can design your own storage mechanism and pass the key dynamically

Subject: Remove GCM mode from CI_Encryption (OpenSSL)

While openssl_get_cipher_methods() lists 'aes-<keysize>-gcm' as supported,
it appears that this is only half of the story. To be more specific, only
the encryption operation of GCM is performed, and the authentication message
is completely missing, rendering the whole thing useles.

Subject: Return 403 instead of 500 if no CSRF token given

Not supplying a CSRF token shouldn't return a 500 response because it isn't a server error. The response status code should definitely be in the 400's, because it's the client's fault. And it should be a 403 because the client is forbidden from making that request without the appropriate credential (the CSRF token), though the request may be otherwise valid.

 With regular expressions, you can also catch a segment containing a
 forward slash ('/'), which would usually represent the delimiter between
 multiple segments.

 For example, if a user accesses a password protected area of your web
 application and you wish to be able to redirect them back to the same
 page after they log in, you may find this example useful::
 
 	$route['login/(.+)'] = 'auth/login/$1';

 For those of you who don't know regular expressions and want to learn
 more about them, `regular-expressions.info <http://www.regular-expressions.info/>`
 might be a good starting point.

-Open Software License ("OSL") v 3.0
-
-This Open Software License (the "License") applies to any original work of
-authorship (the "Original Work") whose owner (the "Licensor") has placed the
-following licensing notice adjacent to the copyright notice for the Original
-Work:
-
-Licensed under the Open Software License version 3.0
-
-1) Grant of Copyright License. Licensor grants You a worldwide, royalty-free,
-non-exclusive, sublicensable license, for the duration of the copyright, to do
-the following:
-
-	a) to reproduce the Original Work in copies, either alone or as part of a
-		collective work;
-
-	b) to translate, adapt, alter, transform, modify, or arrange the Original
-		Work, thereby creating derivative works ("Derivative Works") based
-		upon the Original Work;
-
-	c) to distribute or communicate copies of the Original Work and Derivative
-		Works to the public, with the proviso that copies of Original Work or
-		Derivative Works that You distribute or communicate shall be licensed
-		under this Open Software License;
-
-	d) to perform the Original Work publicly; and
-
-	e) to display the Original Work publicly.
-
-2) Grant of Patent License. Licensor grants You a worldwide, royalty-free,
-non-exclusive, sublicensable license, under patent claims owned or controlled
-by the Licensor that are embodied in the Original Work as furnished by the
-Licensor, for the duration of the patents, to make, use, sell, offer for sale,
-have made, and import the Original Work and Derivative Works.
-
-3) Grant of Source Code License. The term "Source Code" means the preferred
-form of the Original Work for making modifications to it and all available
-documentation describing how to modify the Original Work. Licensor agrees to
-provide a machine-readable copy of the Source Code of the Original Work along
-with each copy of the Original Work that Licensor distributes. Licensor
-reserves the right to satisfy this obligation by placing a machine-readable
-copy of the Source Code in an information repository reasonably calculated to
-permit inexpensive and convenient access by You for as long as Licensor
-continues to distribute the Original Work.
-
-4) Exclusions From License Grant. Neither the names of Licensor, nor the names
-of any contributors to the Original Work, nor any of their trademarks or
-service marks, may be used to endorse or promote products derived from this
-Original Work without express prior permission of the Licensor. Except as
-expressly stated herein, nothing in this License grants any license to
-Licensor's trademarks, copyrights, patents, trade secrets or any other
-intellectual property. No patent license is granted to make, use, sell, offer
-for sale, have made, or import embodiments of any patent claims other than the
-licensed claims defined in Section 2. No license is granted to the trademarks
-of Licensor even if such marks are included in the Original Work. Nothing in
-this License shall be interpreted to prohibit Licensor from licensing under
-terms different from this License any Original Work that Licensor otherwise
-would have a right to license.
-
-5) External Deployment. The term "External Deployment" means the use,
-distribution, or communication of the Original Work or Derivative Works in any
-way such that the Original Work or Derivative Works may be used by anyone
-other than You, whether those works are distributed or communicated to those
-persons or made available as an application intended for use over a network.
-As an express condition for the grants of license hereunder, You must treat
-any External Deployment by You of the Original Work or a Derivative Work as a
-distribution under section 1(c).
-
-6) Attribution Rights. You must retain, in the Source Code of any Derivative
-Works that You create, all copyright, patent, or trademark notices from the
-Source Code of the Original Work, as well as any notices of licensing and any
-descriptive text identified therein as an "Attribution Notice." You must cause
-the Source Code for any Derivative Works that You create to carry a prominent
-Attribution Notice reasonably calculated to inform recipients that You have
-modified the Original Work.
-
-7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that
-the copyright in and to the Original Work and the patent rights granted herein
-by Licensor are owned by the Licensor or are sublicensed to You under the
-terms of this License with the permission of the contributor(s) of those
-copyrights and patent rights. Except as expressly stated in the immediately
-preceding sentence, the Original Work is provided under this License on an "AS
-IS" BASIS and WITHOUT WARRANTY, either express or implied, including, without
-limitation, the warranties of non-infringement, merchantability or fitness for
-a particular purpose. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK
-IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this
-License. No license to the Original Work is granted by this License except
-under this disclaimer.
-
-8) Limitation of Liability. Under no circumstances and under no legal theory,
-whether in tort (including negligence), contract, or otherwise, shall the
-Licensor be liable to anyone for any indirect, special, incidental, or
-consequential damages of any character arising as a result of this License or
-the use of the Original Work including, without limitation, damages for loss
-of goodwill, work stoppage, computer failure or malfunction, or any and all
-other commercial damages or losses. This limitation of liability shall not
-apply to the extent applicable law prohibits such limitation.
-
-9) Acceptance and Termination. If, at any time, You expressly assented to this
-License, that assent indicates your clear and irrevocable acceptance of this
-License and all of its terms and conditions. If You distribute or communicate
-copies of the Original Work or a Derivative Work, You must make a reasonable
-effort under the circumstances to obtain the express assent of recipients to
-the terms of this License. This License conditions your rights to undertake
-the activities listed in Section 1, including your right to create Derivative
-Works based upon the Original Work, and doing so without honoring these terms
-and conditions is prohibited by copyright law and international treaty.
-Nothing in this License is intended to affect copyright exceptions and
-limitations (including "fair use" or "fair dealing"). This License shall
-terminate immediately and You may no longer exercise any of the rights granted
-to You by this License upon your failure to honor the conditions in Section
-1(c).
-
-10) Termination for Patent Action. This License shall terminate automatically
-and You may no longer exercise any of the rights granted to You by this
-License as of the date You commence an action, including a cross-claim or
-counterclaim, against Licensor or any licensee alleging that the Original Work
-infringes a patent. This termination provision shall not apply for an action
-alleging patent infringement by combinations of the Original Work with other
-software or hardware.
-
-11) Jurisdiction, Venue and Governing Law. Any action or suit relating to this
-License may be brought only in the courts of a jurisdiction wherein the
-Licensor resides or in which Licensor conducts its primary business, and under
-the laws of that jurisdiction excluding its conflict-of-law provisions. The
-application of the United Nations Convention on Contracts for the
-International Sale of Goods is expressly excluded. Any use of the Original
-Work outside the scope of this License or after its termination shall be
-subject to the requirements and penalties of copyright or patent law in the
-appropriate jurisdiction. This section shall survive the termination of this
-License.
-
-12) Attorneys' Fees. In any action to enforce the terms of this License or
-seeking damages relating thereto, the prevailing party shall be entitled to
-recover its costs and expenses, including, without limitation, reasonable
-attorneys' fees and costs incurred in connection with such action, including
-any appeal of such action. This section shall survive the termination of this
-License.
-
-13) Miscellaneous. If any provision of this License is held to be
-unenforceable, such provision shall be reformed only to the extent necessary
-to make it enforceable.
-
-14) Definition of "You" in This License. "You" throughout this License,
-whether in upper or lower case, means an individual or a legal entity
-exercising rights under, and complying with all of the terms of, this License.
-For legal entities, "You" includes any entity that controls, is controlled by,
-or is under common control with you. For purposes of this definition,
-"control" means (i) the power, direct or indirect, to cause the direction or
-management of such entity, whether by contract or otherwise, or (ii) ownership
-of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial
-ownership of such entity.
-
-15) Right to Use. You may use the Original Work in all ways not otherwise
-restricted or conditioned by this License or by law, and Licensor promises not
-to interfere with or be responsible for such uses by You.
-
-16) Modification of This License. This License is Copyright © 2005 Lawrence
-Rosen. Permission is granted to copy, distribute, or communicate this License
-without modification. Nothing in this License permits You to modify this
-License as applied to the Original Work or to Derivative Works. However, You
-may modify the text of this License and copy, distribute or communicate your
-modified version (the "Modified License") and apply it to other original works
-of authorship subject to the following conditions: (i) You may not indicate in
-any way that your Modified License is the "Open Software License" or "OSL" and
-you may not use those names in the name of your Modified License; (ii) You
-must replace the notice specified in the first paragraph above with the notice
-"Licensed under <insert your license name here>" or with a notice of your own
-that is not confusingly similar to the notice in this License; and (iii) You
-may not claim that your original works are open source software unless your
-Modified License has been approved by Open Source Initiative (OSI) and You
-comply with its license review and certification process.

From f7c8ea2dafc9c007c5363ed33e323344bee18944 Mon Sep 17 00:00:00 2001
From: James L Parry <jim_parry@bcit.ca>
Date: Tue, 28 Oct 2014 15:28:27 -0700
Subject: Revert to default sphinx theme

Remove dependency on EllisLab corporate theme - that is not appropriate for us.
Reverted to default Sphinx theme, with a couple of options, which have the side-effect of adding back document tree navigation (next/previous) and collapsible menu (albeit a sidebar not a top one).

Closes #2605 and closes #2354, for now.
This is not a proper styling - that is a separate issue!

+***************************
+Tips for a Good Issue Report
+***************************
+
+Use a descriptive subject line (eg parser library chokes on commas) rather than a vague one (eg. your code broke).
+
+Address a single issue in a report.
+
+Identify the CodeIgniter version (eg 3.0-develop) and the component if you know it (eg. parser library)
+
+Explain what you expected to happen, and what did happen.
+Include error messages and stacktrace, if any.
+
+Include short code segments if they help to explain.
+Use a pastebin or dropbox facility to include longer segments of code or screenshots - do not include them in the issue report itself.
+This means setting a reasonable expiry for those, until the issue is resolved or closed.
+
+If you know how to fix the issue, you can do so in your own fork & branch, and submit a pull request.
+The issue report information above should be part of that.
+
+If your issue report can describe the steps to reproduce the problem, that is great.
+If you can include a unit test that reproduces the problem, that is even better, as it gives whoever is fixing
+it a clearer target!

+Handling Multiple Languages
+***************************

+If you want to support multiple languages in your application, you would provide folders inside

+

+`internationalization and localization <http://en.wikipedia.org/wiki/Internationalization_and_localization>`_.
+
+We use the term "idiom" to refer to a language using its common name, 
+rather than using any of the international standards, such as "en", "en-US", or "en-CA-x-ca" for English
+and some of its variants.
+
+.. note:: There is nothing to prevent you from using those abbreviations in your application!

3) Added default setting to query builder configuration writeup.

       -  Changed default value of the ``$xss_clean`` parameter to NULL for all methods that utilize it, the default value is now determined by the ``$config['global_xss_filtering']`` setting.
       -  Added method ``post_get()`` and changed ``get_post()`` to search in GET data first. Both methods' names now properly match their GET/POST data search priorities.
       -  Changed method ``_fetch_from_array()`` to parse array notation in field name.
+      -  Changed method ``_fetch_from_array()`` to allow retrieving multiple fields at once by passing $index as an array.
       -  Added an option for ``_clean_input_keys()`` to return FALSE instead of terminating the whole script.
       -  Deprecated the ``is_cli_request()`` method, it is now an alias for the new :func:`is_cli()` common function.
       -  Added an ``$xss_clean`` parameter to method ``user_agent()`` and removed the ``$user_agent`` property.

       -  Changed default value of the ``$xss_clean`` parameter to NULL for all methods that utilize it, the default value is now determined by the ``$config['global_xss_filtering']`` setting.
       -  Added method ``post_get()`` and changed ``get_post()`` to search in GET data first. Both methods' names now properly match their GET/POST data search priorities.
       -  Changed method ``_fetch_from_array()`` to parse array notation in field name.

       -  Added an option for ``_clean_input_keys()`` to return FALSE instead of terminating the whole script.
       -  Deprecated the ``is_cli_request()`` method, it is now an alias for the new :func:`is_cli()` common function.
       -  Added an ``$xss_clean`` parameter to method ``user_agent()`` and removed the ``$user_agent`` property.

 CodeIgniter provides a library to help you with certain common functions
 that you may want to use with Javascript. Please note that CodeIgniter
 does not require the jQuery library to run, and that any scripting
 library will work equally well. The jQuery library is simply presented
 as a convenience if you choose to use it.

-$this->db->list_fields()
-=========================
-
-Returns an array containing the field names. This query can be called
-two ways:
-
-1. You can supply the table name and call it from the $this->db->
-object::
-
-	$fields = $this->db->list_fields('table_name');
-	
-	foreach ($fields as $field)
-	{
-		echo $field;
-	}
-
-2. You can gather the field names associated with any query you run by
-calling the function from your query result object::
-
-	$query = $this->db->query('SELECT * FROM some_table');
-	
-	foreach ($query->list_fields() as $field)
-	{
-		echo $field;
-	}
-
-$this->db->field_exists()
-==========================
-
-Sometimes it's helpful to know whether a particular field exists before
-performing an action. Returns a boolean TRUE/FALSE. Usage example::
-
-	if ($this->db->field_exists('field_name', 'table_name'))
-	{
-		// some code...
-	}
-
-.. note:: Replace *field_name* with the name of the column you are looking
-	for, and replace *table_name* with the name of the table you are
-	looking for.
-
-$this->db->field_data()
-========================
-
-Returns an array of objects containing field information.
-
-Sometimes it's helpful to gather the field names or other metadata, like
-the column type, max length, etc.
-
-.. note:: Not all databases provide meta-data.
-
-Usage example::
-
-	$fields = $this->db->field_data('table_name');
-	
-	foreach ($fields as $field)
-	{
-		echo $field->name;
-		echo $field->type;
-		echo $field->max_length;
-		echo $field->primary_key;

-
-If you have run a query already you can use the result object instead of
-supplying the table name::
-
-	$query = $this->db->query("YOUR QUERY");
-	$fields = $query->field_data();
-
-The following data is available from this function if supported by your
-database:
-
--  name - column name
--  max_length - maximum length of the column
--  primary_key - 1 if the column is a primary key
--  type - the type of the column

 - Removed a test that was created specifically for the 'convert programmatic characters to entities' feature.
 - Changed filter_uri() to accept by reference and to not return anything as its only purpose now is to trigger a show_error() call.
 - Added changelog messages and updated the upgrade instructions.

Subject: Remove output minifier

This feature has proven to be problematic and it's not nearly
as flexible as a dedicated minifier library like Minify
(http://www.minifier.org/, https://github.com/matthiasmullie/minify).

The same results in terms of saving traffic can also be achievied via
gzip compression (which should also be done on the httpd level, but we
also support anyway) and stuff like mod_pagespeed.

Reverts PR #965

Related issues as a track record proving how problematic this has been:

#2078 #1499 #2163 #2092 #2387 #2637 #2710 #2120 #2171 #2631 #2326 #2795
#2791 #2772

Additionally, the count of contributors suggesting that the only way
to fix the minifier problems is to remove it, is around the same as
the count of people suggesting the feature to be implemented in the
first place. It was experimental anyway ... the experiment failed.

+###################
+DB Driver Reference
+###################
+
+This is the platform-independent base DB implementation class.
+This class will not be called directly. Rather, the adapter
+class for the specific database will extend and instantiate it.
+
+The how-to material for this has been split over several articles.
+This article is intended to be a reference for them.
+
+.. class:: CI_DB_driver
+
+	.. method:: initialize()
+
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Initialize Database Settings; 
+                establish a connection to the database.
+
+	.. method:: db_pconnect()
+
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Establish a persistent database connection
+
+	.. method:: reconnect()
+
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Keep / reestablish the db connection if no queries have been
+                sent for a length of time exceeding the server's idle timeout.
+
+                This is only available in drivers that support it.
+
+	.. method:: db_select()
+
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Select database
+
+	.. method:: db_set_charset($charset)
+
+		:param	string	$charset: Character set name
+		:returns:	TRUE on success, FALSE on failure
+		:rtype:	boolean
+
+		Set client character set
+
+	.. method:: platform()
+
+		:returns:	Platform name
+		:rtype:	string
+
+		The name of the platform in use (mysql, mssql, etc...)
+
+	.. method:: version()
+
+		:returns:	The version of the database being used.
+		:rtype:	string
+
+		Database version number
+
+	.. method:: query($sql[, $binds = FALSE[, $return_object = NULL]]])
+
+		:param	string	$sql: The SQL statement to execute
+		:param	array	$binds: An array of binding data
+		:param	bool	$return_object: Character set name
+		:returns:	True on "update" success, DB_result object on "query" success, FALSE on failure
+		:rtype:	mixed
+
+		Execute the query
+
+                Accepts an SQL string as input and returns a result object 
+                upon
+                successful execution of a "read" type query. Returns boolean 
+                TRUE
+                upon successful execution of a "write" type query. 
+                Returns boolean
+                FALSE upon failure, and if the $db_debug variable is set 
+                to TRUE
+                will raise an error.
+
+	.. method:: load_rdriver()
+
+		:returns:	The DB_result object appropriate for the driver in use
+		:rtype:	DB_result
+
+		Load the result drivers

+		:rtype:	mixed
+
+		Simple Query
+
+                This is a simplified version of the query() function. Internally
+                we only use it when running transaction commands since they do
+                not require all the features of the main query() function.
+
+	.. method:: trans_off()
+
+		:rtype:	void
+
+		Disable Transactions.
+
+                This permits transactions to be disabled at run-time.

+		:rtype:	void
+
+		Enable/disable Transaction Strict Mode.

+                groups of
+                transactions, if one group fails all groups will be rolled back.
+                If strict mode is disabled, each group is treated autonomously, 
+                meaning
+                a failure of one group will not affect any others.
+
+	.. method:: trans_start([$test_mode = FALSE[)
+
+		:param	boolean	$test_mode: TRUE for testing mode
+		:rtype:	void
+
+		Start Transaction.
+
+	.. method:: trans_complete()
+
+		:rtype:	void
+
+		Complete Transaction.
+
+	.. method:: trans_status()
+
+                :returns:   TRUE if the transaction succeeded, FALSE if it failed
+		:rtype:	boolean
+
+		Lets you retrieve the transaction flag to determine if it
+                has failed.
+
+	.. method:: compile_binds($sql, $binds)
+
+		:param	string	$sql: The SQL statement 
+		:param	array	$binds: An array of binding data
+		:returns:	The updated SQL statement
+		:rtype:	string
+
+		Compile Bindings
+
+	.. method:: is_write_type($sql)
+
+		:param	string	$sql: The SQL statement 
+		:returns:	TRUE if the SQL statement is a "write" type of statement
+		:rtype:	boolean
+
+		Determines if a query is a "write" type.
+
+	.. method:: elapsed_time([$decimals = 6])
+
+		:param	int	$decimals: The number of decimal places
+		:returns:	The aggregate query elapsed time, in microseconds
+		:rtype:	string
+
+		Calculate the aggregate query elapsed time.
+
+	.. method:: total_queries()
+
+		:returns:	The total number of queries
+		:rtype:	int
+
+		Returns the total number of queries.
+
+	.. method:: last_query()
+
+		:returns:	The last query executed
+		:rtype:	string
+
+		Returns the last query that was executed.
+
+	.. method:: escape($str)
+
+		:param	string	$str: The string to work with
+		:returns:	The escaped string
+		:rtype:	mixed
+
+		"Smart" Escape String.
+
+                Escapes data based on type.
+                Sets boolean and null types
+
+	.. method:: escape_str($str[, $like = FALSE])

+                the table prefix onto it. Some logic is necessary in order 
+                to deal with
+                column names that include the path. Consider a query like this::
+                
+                        SELECT * FROM hostname.database.table.column AS c FROM hostname.database.table
+                
+                Or a query with aliasing::
+                
+                        SELECT m.member_id, m.member_name FROM members AS m
+                
+                Since the column name can include up to four segments 
+                (host, DB, table, column)
+                or also have an alias prefix, we need to do a bit of work 
+                to figure this out and
+                insert the table prefix (if it exists) in the proper position, 
+                and escape only
+                the correct identifiers.

+#############################
+Upgrading from 2.1.4 to 2.2.0
+#############################
+
+.. note:: The :doc:`Encrypt Class <libraries/encrypt>` now requires the
+	Mcrypt extension. If you were previously using the Encrypt Class
+	without Mcrypt, then this is a breaking change.  You must install
+	the Mcrypt extension in order to upgrade. For information on
+	installing Mcrypt please see the PHP `documentation
+	<http://php.net/manual/en/mcrypt.setup.php>`.
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace all files and directories in your "system" folder.
+
+.. note:: If you have any custom developed files in these folders please
+	make copies of them first.

Subject: User Guide Tuning

Adjust the heading levels in the writeups for the input, loader, security and unit testing libraries, to match the other library writeups.
Specifically, the class reference section in each of these was appearing as a sub-level in the toctree, when it should be at the same level.

+A largely unknown rule about XSS cleaning is that it should *only be
+applied to output*, as opposed to input data.
+
+We've made that mistake ourselves with our automatic and global XSS cleaning
+feature (see step 13 above), so now in an effort to discourage that
+practice, we're also removing 'xss_clean' from the officially supported
+list of :doc:`form validation <../libraries/form_validation>` rules.
+
+Because the :doc:`Form Validation library <../libraries/form_validation>`
+generally validates *input* data, the 'xss_clean' rule simply doesn't
+belong in it.
+
+If you really, really need to apply that rule, you should now also load the
+:doc:`Security Helper <../helpers/security_helper>`, which contains
+``xss_clean()`` as a regular function and therefore can be also used as
+a validation rule.

 Initializing a Session
 ======================
 
-Sessions will typically run globally with each page load, so the session

+For the most part the session class will run unattended in the background,

 To initialize the Session class manually in your controller constructor,

-	$this->load->driver('session');
+	$this->load->library('session');
 
 Once loaded, the Sessions library object will be available using::
 
 	$this->session
 
+.. important:: Because the :doc:`Loader Class <../loader>` is instantiated
+	by CodeIgniter's base controller, make sure to call
+	``parent::__construct()`` before trying to load a library from
+	inside a controller constructor.
+
 How do Sessions work?
 =====================
 
 When a page is loaded, the session class will check to see if valid
-session data exists in the user's session. If sessions data does **not**
-exist (or if it has expired) a new session will be created and saved.
-If a session does exist, its information will be updated. With each update,
-the session_id will be regenerated.

+**not** exist (or if it doesn't match one stored on the server or has
+expired) a new session will be created and saved.
+
+If a valid session does exist, its information will be updated. With each
+update, the session ID may be regenerated if configured to do so.
 
 It's important for you to understand that once initialized, the Session
 class runs automatically. There is nothing you need to do to cause the
-above behavior to happen. You can, as you'll see below, work with
-session data or even add your own data to a user's session, but the

+data, but the process of reading, writing, and updating a session is
+automatic.
+
+.. note:: Under CLI, the Session library will automatically halt itself,
+	as this is a concept based entirely on the HTTP protocol.
 
 What is Session Data?
 =====================
 
-A *session*, as far as CodeIgniter is concerned, is simply an array
-containing the following information:
-
--  The user's unique Session ID (this is a statistically random string
-   with very strong entropy, hashed with MD5 for portability, and
-   regenerated (by default) every five minutes)
--  The user's IP Address
--  The user's User Agent data (the first 120 characters of the browser
-   data string)
--  The "last activity" time stamp.
-
-The above data is stored in a cookie as a serialized array with this
-prototype::
-
-	[array]
-	(
-		'session_id'    => random hash,
-		'ip_address'    => 'string - user IP address',
-		'user_agent'    => 'string - user agent data',
-		'last_activity' => timestamp
-	)
-
-.. note:: Sessions are only updated every five minutes by default to
-	reduce processor load. If you repeatedly reload a page you'll notice
-	that the "last activity" time only updates if five minutes or more has
-	passed since the last time the cookie was written. This time is
-	configurable by changing the $config['sess_time_to_update'] line in
-	your system/config/config.php file.
+Session data is simply an array associated with a particular session ID
+(cookie).
+
+If you've used sessions in PHP before, you should be familiar with PHP's
+`$_SESSION superglobal <http://php.net/manual/en/reserved.variables.session.php>`_
+(if not, please read the content on that link).
+
+CodeIgniter gives access to its session data through the same means, as it
+uses the session handlers' mechanism provided by PHP. Using session data is
+as simple as manipulating (read, set and unset values) the ``$_SESSION``
+array.
+
+In addition, CodeIgniter also provides 2 special types of session data
+that are further explained below: flashdata and tempdata.
+
+.. note:: In previous versions, regular session data in CodeIgniter was
+	referred to as 'userdata'. Have this in mind if that term is used
+	elsewhere in the manual. Most of it is written to explain how
+	the custom 'userdata' methods work.
 
 Retrieving Session Data
 =======================
 
-Any piece of information from the session array is available using the
-following function::
+Any piece of information from the session array is available through the
+``$_SESSION`` superglobal::
+
+	$_SESSION['item']
+
+Or through the magic getter::
+
+	$this->session->item
+
+And for backwards compatibility, through the ``userdata()`` method::
 
 	$this->session->userdata('item');
 
-Where item is the array index corresponding to the item you wish to
-fetch. For example, to fetch the session ID you will do this::
+Where item is the array key corresponding to the item you wish to fetch.
+For example, to assign a previously stored 'name' item to the ``$name``
+variable, you will do this::
+
+	$name = $_SESSION['name'];
+
+	// or:
 
-	$session_id = $this->session->userdata('session_id');
+	$name = $this->session->name
 
-.. note:: The function returns NULL if the item you are
-	trying to access does not exist.
+	// or:
+
+	$name = $this->session->userdata('name');
+
+.. note:: The ``userdata()`` method returns NULL if the item you are trying
+	to access does not exist.
 
 If you want to retrieve all of the existing userdata, you can simply
-omit the item key parameter::
+omit the item key (magic getter only works for properties)::
 
-	$this->session->userdata();
+	$_SESSION
 
-	/**
-	 * Produces something similar to:
-	 *
-	 *	Array
-	 *	(

-Adding Custom Session Data
-==========================
+	// or:
+
+	$this->session->userdata();
 
-A useful aspect of the session array is that you can add your own data
-to it and it will be stored in the user's cookie. Why would you want to
-do this? Here's one example:
+Adding Session Data
+===================
 
 Let's say a particular user logs into your site. Once authenticated, you
-could add their username and email address to the session, making

+data globally available to you without having to run a database query when

+
+You can simply assign data to the ``$_SESSION`` array, as with any other
+variable. Or as a property of ``$this->session``.
 
-To add your data to the session array involves passing an array
-containing your new data to this function::
+Alternatively, the old method of assigning it as "userdata" is also
+available. That however passing an array containing your new data to the
+``set_userdata()`` method::
 
 	$this->session->set_userdata($array);
 
-Where $array is an associative array containing your new data. Here's an

+
+Or you can call ``has_userdata()``::

 Removing Session Data
 =====================
 
-Just as set_userdata() can be used to add information into a session,
-unset_userdata() can be used to remove it, by passing the session key.
-For example, if you wanted to remove 'some_name' from your session
-information::
+Just as with any other variable, unsetting a value in ``$_SESSION`` can be
+done through ``unset()``::
 
-	$this->session->unset_userdata('some_name');
+	unset($_SESSION['some_name']);
 
+	// or multiple values:
 
-This function can also be passed an associative array of items to unset.
+	unset(
+		$_SESSION['some_name'],
+		$_SESSION['another_name']
+	);
 
-::
+Also, just as ``set_userdata()`` can be used to add information to a
+session, ``unset_userdata()`` can be used to remove it, by passing the

+session data array::
+
+	$this->session->unset_userdata('some_name');
+
+This method also accepts an associative array of items to unset::
 
 	$array_items = array('username' => '', 'email' => '');
 
 	$this->session->unset_userdata($array_items);

 Flashdata
 =========

-cleared. These can be very useful, and are typically used for
-informational or status messages (for example: "record 2 deleted").

+
+This can be very useful, especially for one-time informational, error or

+
+It should be noted that flashdata variables are regular session vars,
+only marked in a specific way under the '__ci_vars' key (please don't touch
+that one, you've been warned).
 
-.. note:: Flash variables are prefaced with "flash\_" so avoid this prefix

+
+If you want to mark multiple items as flashdata, simply pass the keys as an
+array::
+
+	$this->session->mark_as_flash(array('item', 'item2'));
 
 To add flashdata::
 
-	$this->session->set_flashdata('item', 'value');
+	$_SESSION['item'] = 'value';
+	$this->session->mark_as_flash('item');

+
+Accessing session metadata
+==========================
+
+In previous CodeIgniter versions, the session data array included 4 items
+by default: 'session_id', 'ip_address', 'user_agent', 'last_activity'.
+
+This was due to the specifics of how sessions worked, but is now no longer
+necessary with our new implementation. However, it may happen that your
+application relied on these values, so here are alternative methods of
+accessing them::
+
+  - session_id: ``session_id()``
+  - ip_address: ``$_SERVER['REMOTE_ADDR']``
+  - user_agent: ``$this->input->user_agent()`` (unused by sessions)
+  - last_activity: Depends on the storage, no straightforward way. Sorry!
 
 Session Preferences
 ===================
 
+CodeIgniter will usually make everything work out of the box. However,
+Sessions are a very sensitive component of any application, so some
+careful configuration must be done. Please take your time to consider
+all of the options and their effects.

 You'll find the following Session related preferences in your

 Session Drivers
 ===============
 
-By default, the `Cookie Driver`_ is loaded when a session is initialized.
-However, any valid driver may be selected with the $config['sess_driver']
-line in your config.php file.
-
-The session driver library comes with the cookie and native drivers
-installed, and `Custom Drivers`_ may also be installed by the user.
-
-Typically, only one driver will be used at a time, but CodeIgniter does
-support loading multiple drivers. If a specific valid driver is called, it
-will be automatically loaded. Or, an additional driver may be explicitly
-loaded by ``calling load_driver()``::
-
-	$this->session->load_driver('native');
-
-The Session library keeps track of the most recently selected driver to call
-for driver methods. Normally, session class methods are called directly on
-the parent class, as illustrated above. However, any methods called through
-a specific driver will select that driver before invoking the parent method.
-
-So, alternation between multiple drivers can be achieved by specifying which
-driver to use for each call::
-
-	$this->session->native->set_userdata('foo', 'bar');
-
-	$this->session->cookie->userdata('foo');
-
-	$this->session->native->unset_userdata('foo');
-
-Notice in the previous example that the *native* userdata value 'foo'
-would be set to 'bar', which would NOT be returned by the call for
-the *cookie* userdata 'foo', nor would the *cookie* value be unset by
-the call to unset the *native* 'foo' value. The drivers maintain independent
-sets of values, regardless of key names.
-
-A specific driver may also be explicitly selected for use by pursuant
-methods with the ``select_driver()`` call::
-
-	$this->session->select_driver('native');
-
-	$this->session->userdata('item');	// Uses the native driver
-
-Cookie Driver
--------------
-
-The Cookie driver stores session information for each user as serialized
-(and optionally encrypted) data in a cookie. It can also store the session
-data in a database table for added security, as this permits the session ID
-in the user's cookie to be matched against the stored session ID. By default
-only the cookie is saved. If you choose to use the database option you'll
-need to create the session table as indicated below.
-
-If you have the encryption option enabled, the serialized array will be
-encrypted before being stored in the cookie, making the data highly
-secure and impervious to being read or altered by someone. More info
-regarding encryption can be :doc:`found here <encryption>`, although
-the Session class will take care of initializing and encrypting the data
-automatically.
-
-.. note:: Even if you are not using encrypted sessions, you must set
-	an :doc:`encryption key <./encryption>` in your config file which is used
-	to aid in preventing session data manipulation.
-
-.. note:: Cookies can only hold 4KB of data, so be careful not to exceed
-	the capacity. The encryption process in particular produces a longer
-	data string than the original so keep careful track of how much data you
-	are storing.
-
-Saving Session Data to a Database
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-While the session data array stored in the user's cookie contains a
-Session ID, unless you store session data in a database there is no way
-to validate it. For some applications that require little or no
-security, session ID validation may not be needed, but if your
-application requires security, validation is mandatory. Otherwise, an
-old session could be restored by a user modifying their cookies.
-
-When session data is available in a database, every time a valid session
-is found in the user's cookie, a database query is performed to match
-it. If the session ID does not match, the session is destroyed. Session
-IDs can never be updated, they can only be generated when a new session
-is created.
-
-In order to store sessions, you must first create a database table for
-this purpose. Here is the basic prototype (for MySQL) required by the
-session class::
-
-	CREATE TABLE IF NOT EXISTS  `ci_sessions` (
-		session_id varchar(40) DEFAULT '0' NOT NULL,
-		ip_address varchar(45) DEFAULT '0' NOT NULL,
-		user_agent varchar(120) NOT NULL,
-		last_activity int(10) unsigned DEFAULT 0 NOT NULL,
-		user_data text NOT NULL,
-		PRIMARY KEY (session_id, ip_address, user_agent),
-		KEY `last_activity_idx` (`last_activity`)
+As already mentioned, the Session library comes with 4 drivers, or storage
+engines, that you can use:
+
+  - files
+  - database
+  - redis
+  - memcached
+
+By default, the `Files Driver`_ will be used when a session is initialized,
+because it is the most safe choice and is expected to work everywhere
+(virtually every environment has a file system).
+
+However, any other driver may be selected via the ``$config['sess_driver']``
+line in your **application/config/config.php** file, if you chose to do so.
+Have it in mind though, every driver has different caveats, so be sure to
+get yourself familiar with them (below) before you make that choice.
+
+In addition, you may also create and use `Custom Drivers`_, if the ones
+provided by default don't satisfy your use case.
+
+.. note:: In previous CodeIgniter versions, a different, "cookie driver"
+	was the only option and we have received negative feedback on not
+	providing that option. While we do listen to feedback from the
+	community, we want to warn you that it was dropped because it is
+	**unsafe** and we advise you NOT to try to replicate it via a
+	custom driver.
+
+Files Driver
+------------
+
+The 'files' driver uses your file system for storing session data.
+
+It can safely be said that it works exactly like PHP's own default session
+implementation, but in case this is an important detail for you, have it
+mind that it is in fact not the same code and it has some limitations
+(and advantages).
+
+To be more specific, it doesn't support PHP's `directory level and mode
+formats used in session.save_path
+<http://php.net/manual/en/session.configuration.php#ini.session.save-path>`_,
+and it has most of the options hard-coded for safety. Instead, only
+absolute paths are supported for ``$config['sess_save_path']``.
+
+Another important thing that you should know, is to make sure that you
+don't use a publicly-readable or shared directory for storing your session
+files. Make sure that *only you* have access to see the contents of your
+chosen *sess_save_path* directory. Otherwise, anybody who can do that, can
+also steal any of the current sessions (also known as "session fixation"
+attack).
+
+On UNIX-like operating systems, this is usually achieved by setting the
+0600 mode permissions on that directory via the `chmod` command, which
+allows only the directory's owner to perform read and write operations on
+it. But be careful because the system user *running* the script is usually
+not your own, but something like 'www-data' instead, so only setting those
+permissions will probable break your application.
+
+Instead, you should do something like this, depending on your environment
+::
+
+	mkdir /<path to your application directory>/sessions/
+	chmod 0600 /<path to your application directory>/sessions/
+	chown www-data /<path to your application directory>/sessions/
+
+Bonus Tip
+^^^^^^^^^
+
+Some of you will probably opt to choose another session driver because
+file storage is usually slower. This is only half true.
+
+A very basic test will probably trick you into believing that an SQL
+database is faster, but in 99% of the cases, this is only true while you
+only have a few current sessions. As the sessions count and server loads
+increase - which is the time when it matters - the file system will
+consistently outperform almost all relational database setups.
+
+In addition, if performance is your only concern, you may want to look
+into using `tmpfs <http://eddmann.com/posts/storing-php-sessions-file-caches-in-memory-using-tmpfs/>`_,
+(warning: external resource), which can make your sessions blazing fast.
+
+Database Driver
+---------------
+
+The 'database' driver uses a relational database such as MySQL or
+PostgreSQL to store sessions. This is a popular choice among many users,
+because it allows the developer easy access to the session data within
+an application - it is just another table in your database.
+
+However, there are some conditions that must be met:
+
+  - Only your **default** database connection (or the one that you access
+    as ``$this->db`` from your controllers) can be used.
+  - You can NOT use a persistent connection.
+  - You must have the :doc:`Query Builder </database/query_builder>`
+    enabled.
+
+In order to use the 'database' session driver, you must also create this
+table that we already mentioned and then set it as your
+``$config['sess_save_path']`` value.
+For example, if you would like to use 'ci_sessions' as your table name,
+you would do this:
+
+	$config['sess_driver'] = 'database';
+	$config['sess_save_path'] = 'ci_sessions';
+
+.. note:: If you've upgraded from a previous version of CodeIgniter and
+	you don't have 'sess_save_path' configured, then the Session
+	library will look for the old 'sess_table_name' setting and use
+	it instead. Please don't rely on this behavior as it will get
+	removed in the future.
+
+And then of course, create the database table ...
+
+For MySQL::
+
+	CREATE TABLE IF NOT EXISTS `ci_sessions` (
+		`session_id` varchar(40) NOT NULL,
+		`ip_address` varchar(45) NOT NULL,
+		`timestamp` int(10) unsigned DEFAULT 0 NOT NULL,
+		`data` blob DEFAULT '' NOT NULL,
+		PRIMARY KEY (session_id, ip_address),
+		KEY `ci_sessions_timestamp` (`timestamp`)
 	);
 
-Or if you're using PostgreSQL::
+For PostgreSQL::
 
-	CREATE TABLE  ci_sessions (
-		session_id varchar(40) DEFAULT '0' NOT NULL,
-		ip_address varchar(45) DEFAULT '0' NOT NULL,
-		user_agent varchar(120) NOT NULL,
-		last_activity bigint DEFAULT 0 NOT NULL,
-		user_data text NOT NULL,
-		PRIMARY KEY (session_id)
+	CREATE TABLE "ci_sessions" (
+		"session_id" varchar(40) NOT NULL,
+		"ip_address" varchar(45) NOT NULL,
+		"timestamp" bigint DEFAULT 0 NOT NULL,
+		"data" text DEFAULT '' NOT NULL,
+		PRIMARY KEY ("session_id")
 	);
 
-	CREATE INDEX last_activity_idx ON ci_sessions(last_activity);
+	CREATE INDEX "ci_sessions_timestamp" ON "ci_sessions" ("timestamp");
+
+However, if you want to turn on the *sess_match_ip* setting, you should
+also do the following, after creating the table::
+
+	// Works both on MySQL and PostgreSQL
+	ALTER TABLE ci_sessions ADD CONSTRAINT ci_sessions_id_ip UNIQUE (session_id, ip_address);
+
+.. important:: Only MySQL and PostgreSQL databases are officially

+	Using sessions without locks can cause all sorts of problems,
+	especially with heavy usage of AJAX, and we will not support
+	such cases.
+
+Redis Driver
+------------
+
+Redis is a storage engine typically used for caching and popular because
+of its high performance, which is also probably your reason to use the
+'redis' session driver.
+
+The downside is that it is not as ubiquitous as relational databases and
+requires the `phpredis <https://github.com/nicolasff/phpredis>`_ PHP
+extension to be installed on your system, and that one doesn't come
+bundled with PHP.
+Chances are, you're only be using the 'redis' driver only if you're already
+both familiar with Redis and using it for other purposes.
+
+Just as with the 'files' and 'database' drivers, you must also configure
+the storage location for your sessions via the
+``$config['sess_save_path']`` setting.
+The format here is a bit different and complicated at the same time. It is
+best explained by the *phpredis* extension's README file, so we'll simply
+link you to it:
+
+	https://github.com/phpredis/phpredis#php-session-handler
+
+.. warning:: CodeIgniter's Session library does NOT use the actual 'redis'
+	``session.save_handler``. Take note **only** of the path format in
+	the link above.
 
-.. note:: By default the table is called ci_sessions, but you can name
-	it anything you want as long as you update the
-	*application/config/config.php* file so that it contains the name
-	you have chosen. Once you have created your database table you
-	can enable the database option in your config.php file as follows::
+For the most common case however, a simple ``host:port`` pair should be
+sufficient::
 
-		$config['sess_use_database'] = TRUE;
+	$config['sess_driver'] = 'redis';
+	$config['sess_save_path'] = 'tcp://localhost:6379';
 
-	Once enabled, the Session class will store session data in the DB.
+Memcached Driver
+----------------
 
-	Make sure you've specified the table name in your config file as well::
+The 'memcached' driver is very similar to the 'redis' one in all of its
+properties, except perhaps for availability, because PHP's `Memcached
+<http://php.net/memcached>`_ extension is distributed via PECL and some
+Linux distrubutions make it available as an easy to install package.
 
-		$config['sess_table_name'] = 'ci_sessions';
+Other than that, and without any intentional bias towards Redis, there's
+not much different to be said about Memcached - it is also a popular
+product that is usually used for caching and famed for its speed.
 
-.. note:: The Cookie driver has built-in garbage collection which clears
-	out expired sessions so you do not need to write your own routine to do
-	it.
+However, it is worth noting that the only guarantee given by Memcached
+is that setting value X to expire after Y seconds will result in it being
+deleted after Y seconds have passed (but not necessarily that it won't
+expire earlier than that time). This happens very rarely, but should be
+considered as it may result in loss of sessions.
 
-Native Driver
--------------
+The ``$config['sess_save_path']`` format is fairly straightforward here,
+being just a ``host:port`` pair::
 
-The Native driver relies on native PHP sessions to store data in the
-$_SESSION superglobal array. All stored values continue to be available
-through $_SESSION, but flash- and temp- data items carry special prefixes.
+	$config['sess_driver'] = 'memcached';
+	$config['sess_save_path'] = 'localhost:11211';
+
+Bonus Tip
+^^^^^^^^^
+
+Multi-server configuration with an optional *weight* parameter as the
+third colon-separated (``:weight``) value is also supported, but we have
+to note that we haven't tested if that is reliable.
+
+If you want to experiment with this feature (on your own risk), simply
+separate the multiple server paths with commas::
+
+	// localhost will be given higher priority (5) here,
+	// compared to 192.0.2.1 with a weight of 1.
+	$config['sess_save_path'] = 'localhost:11211:5,192.0.2.1:11211:1';
 
 Custom Drivers
 --------------
 
-You may also :doc:`create your own <../general/creating_drivers>` custom
-session drivers. A session driver basically manages an array of name/value
-pairs with some sort of storage mechanism.
+You may also create your own, custom session drivers. However, have it in
+mind that this is typically not an easy task, as it takes a lot of
+knowledge to do it properly.
+
+You need to know not only how sessions work in general, but also how they
+work specifically in PHP, how the underlying storage mechanism works, how
+to handle concurrency, avoid deadlocks (but NOT through lack of locks) and
+last but not least - how to handle the potential security issues, which
+is far from trivial.
+
+Long story short - if you don't know how to do that already in raw PHP,
+you shouldn't be trying to do it within CodeIgniter either. You've been
+warned.
+
+If you only want to add some extra functionality to your sessions, just
+extend the base Session class, which is a lot more easier. Read the
+:doc:`Creating Libraries <../general/creating_libraries>` article to
+learn how to do that.
+
+Now, to the point - there are three general rules that you must follow
+when creating a session driver for CodeIgniter:
+
+  - Put your driver's file under **application/libraries/Session/drivers/**
+    and follow the naming conventions used by the Session class.
+
+    For example, if you were to create a 'dummy' driver, you would have
+    a ``Session_dummy_driver`` class name, that is declared in
+    *application/libraries/Session/drivers/Session_dummy_driver.php*.
 
-To make a new driver, extend CI_Session_driver. Overload the ``initialize()``
-method and read or create session data. Then implement a save handler to
-write changed data to storage (sess_save), a destroy handler to remove
-deleted data (sess_destroy), a regenerate handler to make a new session ID
-(sess_regenerate), and an access handler to expose the data (get_userdata).
-Your initial class might look like::
+  - Extend the ``CI_Session_driver`` class.
 
-	class CI_Session_custom extends CI_Session_driver {
+    This is just a basic class with a few internal helper methods. It is
+    also extendable like any other library, if you really need to do that,
+    but we are not going to explain how ... if you're familiar with how
+    class extensions/overrides work in CI, then you already know how to do
+    it. If not, well, you shouldn't be doing it in the first place.
 
-		protected function initialize()
+
+  - Implement the `SessionHandlerInterface
+    <http://php.net/sessionhandlerinterface>`_ interface.
+
+    .. note:: You may notice that ``SessionHandlerInterface`` is provided
+    	by PHP since version 5.4.0. CodeIgniter will automatically declare
+    	the same interface if you're running an older PHP version.
+
+    The link will explain why and how.
+
+So, based on our 'dummy' driver example above, you'd end up with something
+like this::
+
+	// application/libraries/Session/drivers/Session_dummy_driver.php:
+
+	class CI_Session_dummy_driver extends CI_Session_driver implements SessionHandlerInterface
+	{
+
+		public function __construct(&$params)
+		{
+			// DO NOT forget this
+			parent::__construct($params);
+
+			// Configuration & other initializations
+		}
+
+		public function open($save_path, $name)
 		{
-			// Read existing session data or create a new one
+			// Initialize storage mechanism (connection)
 		}
 
-		public function sess_save()
+		public function read($session_id)
 		{
-			// Save current data to storage
+			// Read session data (if exists), acquire locks
 		}
 
-		public function sess_destroy()
+		public function write($session_id, $session_data)
 		{
-			// Destroy the current session and clean up storage
+			// Create / update session data (it might not exist!)
 		}
 
-		public function sess_regenerate()
+		public function close()
 		{
-			// Create new session ID
+			// Free locks, close connections / streams / etc.
 		}
 
-		public function &get_userdata()
+		public function destroy($session_id)
 		{
-			// Return a reference to your userdata array
+			// Call close() method & destroy data for current session (order may differ)
+		}
+
+		public function gc($maxlifetime)
+		{
+			// Erase data for expired sessions
 		}
 
 	}
 
-Notice that ``get_userdata()`` returns a reference so the parent library is
-accessing the same array the driver object is using. This saves memory
-and avoids synchronization issues during usage.
+If you've done everything properly, you can now set your *sess_driver*
+configuration value to 'dummy' and use your own driver. Congratulations!
+
+***************
+Class Reference
+***************
 
-Put your driver in the libraries/Session/drivers folder anywhere in your
-package paths. This includes the application directory, the system directory,
-or any path you add with ``$CI->load->add_package_path()``. Your driver must be
-named CI_Session_<name>, and your filename must be Session_<name>.php,
-preferably also capitalized, such as::
+.. class:: CI_Session
 
-	CI_Session_foo in libraries/Session/drivers/Session_foo.php
+	.. method:: userdata([$key = NULL])
 
-Then specify the driver by setting 'sess_driver' in your config.php file or as a
-parameter when loading the CI_Session object::

-*********************************************************
-Step 6: Convert your Session usage from library to driver
-*********************************************************
+*****************************************
+Step 6: Update your Session library usage
+*****************************************
 
-When you load (or autoload) the Session library, you must now load it as a driver instead of a library. This means
-calling ``$this->load->driver('session')`` instead of ``$this->load->library('session')`` and/or listing 'session'
-in ``$autoload['drivers']`` instead of ``$autoload['libraries']``.
+The :doc:`Session Library </libraries/session>` has been completely
+re-written in CodeIgniter 3 and now comes with a bunch of new features,
+but that also means that there are changes that you should make ...
 
-With the change from a single Session Library to the new Session Driver, two new config items have been added:
+Most notably, - the library now uses separate storage drivers instead of
+always relying on (encrypted) cookies.
+In fact, cookies as storage have now been removed and you must always use
+some kind of server-side storage engine, with the file-system being the
+default option.
 
-   -  ``$config['sess_driver']`` selects which driver to initially load. Options are:
-       -  'cookie' (the default) for classic CodeIgniter cookie-based sessions
-       -  'native' for native PHP Session support
-       -  the name of a custom driver you have provided (see :doc:`Session Driver <../libraries/sessions>` for more info)
-   -  ``$config['sess_valid_drivers']`` provides an array of additional custom drivers to make available for loading
+The Session Class now utilizes PHP's own mechanisms for building custom
+session handlers, which also means that your session data is now
+accessible via the ``$_SESSION`` superglobal (though, we've kept the
+possibility to use it as "userdata", like you've done until now).
 
-As the new Session Driver library loads the classic Cookie driver by default and always makes 'cookie' and 'native'
-available as valid drivers, neither of these configuration items are required. However, it is recommended that you
-add them for clarity and ease of configuration in the future.
+A few configuration options have been removed and a few have been added.
+You should really read the whole :doc:`Session library manual
+</libraries/session>` for the details, but here's a short list of changes
+that you should make:
 
-If you have written a Session extension, you must move it into a 'Session' sub-directory of 'libraries', following the
-standard for Drivers. Also beware that some functions which are not part of the external Session API have moved into
-the drivers, so your extension may have to be broken down into separate library and driver class extensions.
+  - Set your ``$config['sess_driver']`` value
+
+    It will default to 'files', unles you've previously used
+    ``$config['sess_use_database']``, in which case it will be set to
+    'database'.
+
+  - Set a ``$config['sess_save_path']`` value
+
+    For the 'database' driver, a fallback to ``$config['sess_table_name']``
+    is in place, but otherwise requires you to read the manual for the
+    specific driver of your choice.
+
+  - Update your ``ci_sessions`` table ('database' driver only)
+
+    The table structure has changed a bit, and more specifically:
+
+      - ``user_agent`` field is dropped
+      - ``user_data`` field is renamed to ``data`` and under MySQL is now of type BLOB
+      - ``last_activity`` field is renamed to ``timestamp``
+
+    This is accompanied by a slight change in the table indexes too, so
+    please read the manual about the :doc:`Session Database Driver
+    </libraries/session#database-driver>` for more information.
+
+    .. important:: Only MySQL and PostgreSQL are officially supported
+    	now. Other databases may still work, but due to lack of advisory
+    	locking features, they are unsafe for concurrent requests and
+    	you should consider using another driver instead.
+
+  - Remove ``$config['sess_match_useragent']``
+
+    The user-agent string is input supplied by the user's browser, or in
+    other words: client side input. As such, it is an ineffective feature
+    and hence why it has been removed.
+
+  - Remove ``$config['sess_encrypt_cookie']``
+
+    As already noted, the library no longer uses cookies as a storage
+    mechanism, which renders this option useless.
+
+  - Remove ``$config['sess_expire_on_close']``
+
+    This option is still usable, but only for backwards compatibility
+    purposes and it should be otherwise removed. The same effect is
+    achieved by setting ``$config['sess_expiration']`` to 0.
+
+  - Check "flashdata" for collisions with "userdata"
+
+    Flashdata is now just regular "userdata", only marked for deletion on
+    the next request. In other words: you can't have both "userdata" and
+    "flashdata" with the same name, because it's the same thing.
+
+  - Check usage of session metadata
+
+    Previously, you could access the 'session_id', 'ip_address',
+    'user_agent' and 'last_activity' metadata items as userdata.
+    This is no longer possible, and you should read the notes about
+    :doc:`Session Metadata </libraries/session#session-metadata>` if your
+    application relies on those values.
+

-      -  Library changed to :doc:`Driver <general/drivers>` with classic 'cookie' driver as the default.
-      -  Added a 'native' PHP Session driver to work with ``$_SESSION``.
-      -  Added a new **tempdata** feature that allows setting userdata items with expiration time (``tempdata()``, ``set_tempdata()``, ``unset_tempdata()``).
-      -  Added default ``$config['sess_driver']`` and ``$config['sess_valid_drivers']`` items to *application/config.php* file.
-      -  Changed 'cookie' driver to respect php.ini's *session.gc_probability* and *session.gc_divisor* settings.
-      -  Changed 'cookie' driver to use HMAC authentication instead of a simple md5 checksum.
-      -  Changed 'cookie' driver to select only one row when using database sessions.
-      -  Changed 'cookie' driver to write to only write to the database at end of page execution.
+      -  Completely re-written the library to use self-contained drivers via ``$config['sess_driver']``.
+      -  Added 'files', 'database', 'redis' and 'memcached' drivers (using 'files' by default).
+      -  Added ``$config['sess_save_path']`` setting to specify where the session data is stored, depending on the driver.
+      -  Dropped support for storing session data in cookies (which renders ``$config['sess_encrypt_cookie']`` useless and is therefore also removed).
+      -  Dropped official  support for storing session data in databases other than MySQL and PostgreSQL.
+      -  Changed table structure for the 'database' driver.
+      -  Added a new **tempdata** feature that allows setting userdata items with expiration time (``mark_as_temp()``, ``tempdata()``, ``set_tempdata()``, ``unset_tempdata()``).
       -  Changed method ``keep_flashdata()`` to also accept an array of keys.
       -  Changed methods ``userdata()``, ``flashdata()`` to return an array of all userdata/flashdata when no parameter is passed.
       -  Deprecated method ``all_userdata()`` - it is now just an alias for ``userdata()`` with no parameters.
       -  Added method ``has_userdata()`` that verifies the existence of a userdata item.
       -  Added *debug* level log messages for key events in the session validation process.
+      -  Dropped support for the *sess_match_useragent* option.

Subject: Remove error suppression from mysql_*connect()

The suppression was kept so far because mysql_connect(),
mysql_pconnect() emit E_DEPRECATION messages on PHP 5.5+.

Well, we already default to 'mysqli' and there's no reason
to use specifically 'mysql' on PHP 5.5, so we might as well
let the deprecation notices appear and encourage users to
switch drivers.

Subject: Revert 7c4d10660a0a47446474bf97e3cb65f80693f1ee

Deprecates form_prep() in favor of html_escape() (again).

Related: issue #1953, which was the reason for the reverted commit,
but was wrongly interpreted and that shouldn't have happened.

Close #2477

-Validate the data
+.. note:: XSS filtering should *only be performed on output*. Filtering
+	input data may modify the data in undesirable ways, including
+	stripping special characters from passwords, which reduces
+	security instead of improving it.
+
+CSRF protection
+===============
+
+CSRF stands for Cross-Site Request Forgery, which is the process of an
+attacker tricking their victim into unknowingly submitting a request.
+
+CodeIgniter provides CSRF protection out of the box, which will get
+automatically triggered for every non-GET HTTP request, but also needs
+you to create your submit forms in a certain way. This is explained in
+the :doc:`Security Library <../libraries/security>` documentation.
+
+Password handling
 =================
 
+It is *critical* that you handle passwords in your application properly.
+
+Unfortunately, many developers don't know how to do that, and the web is
+full of outdated or otherwise wrongful advices, which doesn't help.
+
+We would like to give you a list of combined do's and don'ts to help you
+with that. Please read below.
+
+-  DO NOT store passwords in plain-text format.
+
+   Always **hash** your passwords.
+
+-  DO NOT use Base64 or similar encoding for storing passwords.
+
+   This is as good as storing them in plain-text. Really. Do **hashing**,
+   not *encoding*.
+
+   Encoding, and encryption too, are two-way processes. Passwords are
+   secrets that must only be known to their owner, and thus must work
+   only in one direction. Hashing does that - there's *no* un-hashing or
+   de-hashing, but there is decoding and decryption.
+
+-  DO NOT use weak or broken hashing algorithms like MD5 or SHA1.
+
+   These algorithms are old, proven to be flawed, and not designed for
+   password hashing in the first place.
+
+   Also, DON'T invent your own algorithms.
+
+   Only use strong password hashing algorithms like BCrypt, which is used
+   in PHP's own `Password Hashing <http://php.net/password>`_ functions.
+
+   Please use them, even if you're not running PHP 5.5+, CodeIgniter
+   provides them for you as long as you're running at least PHP version
+   5.3.7 (and if you don't meet that requirement - please, upgrade).
+
+-  DO NOT ever display or send a password in plain-text format!
+
+   Even to the password's owner, if you need a "Forgotten password"
+   feature, just randomly generate a new, one-time (this is also important)
+   password and send that instead.
+
+-  DO NOT put artificial limits on your users' passwords.
+
+   There's no point in forcing a rule that a password can only be up to
+   a number of characters, or that it can't contain a certain set of
+   special characters.
+
+   Not only does this **reduce** security instead of improving it, but
+   there's literally no reason to do it. No technical limitations and
+   no (practical) storage constraints apply once you've hashed them, none!
+
+Validate input data
+===================
+
 CodeIgniter has a :doc:`Form Validation Library
 <../libraries/form_validation>` that assists you in
 validating, filtering, and prepping your data.
 
+Even if that doesn't work for your use case however, be sure to always
+validate and sanitize all input data. For example, if you expect a numeric
+string for an input variable, you can check for that with ``is_numeric()``
+or ``ctype_digit()``. Always try to narrow down your checks to a certain
+pattern.
+
+Have it in mind that this includes not only ``$_POST`` and ``$_GET``
+variables, but also cookies, the user-agent string and basically
+*all data that is not created directly by your own code*.
+
+
 Escape all data before database insertion

       -  Removed method ``is_numeric()`` as it exists as a native PHP function and ``_execute()`` will find and use that (the **is_numeric** rule itself is deprecated since 1.6.1).
       -  Native PHP functions used as rules can now accept an additional parameter, other than the data itself.
       -  Updated method ``set_rules()`` to accept an array of rules as well as a string.
-      -  Added support for ``in`` method that test if a given value is within a given list.
       -  Fields that have empty rules set no longer run through validation (and therefore are not considered erroneous).
       -  Added rule **differs** to check if the value of a field differs from the value of another field.
       -  Added rule **valid_url**.
+      -  Added rule **in_list** to check if the value of a field is within a given list.
       -  Added support for named parameters in error messages.
       -  :doc:`Language <libraries/language>` line keys must now be prefixed with **form_validation_**.

+A note about concurrency
+------------------------
+
+Unless you're developing a website with heavy AJAX usage, you can skip this
+section. If you are, however, and if you're experiencing performance
+issues, then this note is exactly what you're looking for.
+
+Sessions in previous versions of CodeIgniter didn't implement locking,
+which meant that two HTTP requests using the same session could run exactly
+at the same time. To use a more appropriate technical term - requests were
+non-blocking.
+
+However, non-blocking requests in the context of sessions also means
+unsafe, because modifications to session data (or session ID regeneration)
+in one request can interfere with the execution of a second, concurrent
+request. This detail was at the root of many issues and the main reason why
+CodeIgniter 3.0 has a completely re-written Session library.
+
+Why are we telling you this? Because it is likely that after trying to
+find the reason for your performance issues, you may conclude that locking
+is the issue and therefore look into how to remove the locks ...
+
+DO NOT DO THAT! Removing locks would be **wrong** and it will cause you
+more problems!
+
+Locking is not the issue, it is a solution. Your issue is that you still
+have the session open, while you've already processed it and therefore no
+longer need it. So, what you need is to close the session for the
+current request after you no longer need it.
+
+Long story short - call ``session_write_close()`` once you no longer need
+anything to do with session variables.

+Routes containing :any
+======================
+
+Historically, CodeIgniter has always provided the **:any** wildcard in
+routing, with the intention of providing a way to match any character
+**within** an URI segment.
+
+However, the **:any** wildcard is actually just an alias for a regular
+expression and used to be executed in that manner as **.+**. This is
+considered a bug, as it also matches the / (forward slash) character, which
+is the URI segment delimiter and that was never the intention.
 
-However, the **:any** wildcard is actually just an alias for a regular expression
-and used to be executed in that manner as **.+**. This is considered a bug, as it

+There are certainly many developers that have utilized this bug as an actual
+feature. If you're one of them and want to match a forward slash, please use
+the **.+** regular expression::
 
 	(.+)	// matches ANYTHING
 	(:any)	// matches any character, except for '/'
 
+Directories and 'default_controller', '404_override'
+====================================================
+
+As you should know, the ``$route['default_controller']`` and
+``$route['404_override']`` settings accept not only a controller name, but
+also *controller/method* pairs. However, a bug in the routing logic has
+made it possible for some users to use that as *directory/controller*
+instead.
+
+As already said, this behavior was incidental and was never intended, nor
+documented. If you've relied on it, your application will break with
+CodeIgniter 3.0.
+
+Another notable change in version 3 is that 'default_controller' and
+'404_override' are now applied *per directory*. To explain what this means,
+let's take the following example::
+
+	$route['default_controller'] = 'main';
+
+Now, assuming that your website is located at *example.com*, you already
+know that if a user visits ``http://example.com/``, the above setting will
+cause your 'Main' controller to be loaded.
+
+However, what happens if you have an *application/controllers/admin/*
+directory and the user visits ``http://example.com/admin/``?
+In CodeIgniter 3, the router will look for a 'Main' controller under the
+admin/ directory as well. If not found, it will fallback to the parent
+(*application/controllers/*) directory, like in version 2.x.
+
+The same rule applies to the '404_override' setting.
+

 -  Fixed a bug (#3161) - :doc:`Cache Library <libraries/caching>` methods `increment()`, `decrement()` didn't auto-create non-existent items when using redis and/or file storage.
 -  Fixed a bug (#3189) - :doc:`Parser Library <libraries/parser>` used double replacement on ``key->value`` pairs, exposing a potential template injection vulnerability.
 -  Fixed a bug (#3573) - :doc:`Email Library <libraries/email>` violated `RFC5321 <https://tools.ietf.org/rfc/rfc5321.txt>`_ by sending 'localhost.localdomain' as a hostname.

Subject: Fix #3593

Revert "fixes" for #167, #388, #705 (also #1326) as it turns out
URL-decoding isn't compliant with the CGI/1.1 specification.

Subject: Remove 'autoinit' DB setting

It doesn't make sense to do a load->database() call
but not connect to the database. IIRC there was more
stuff in CI_DB_driver::initialize() at some point,
so that was probably the reason why the setting
existed in the first place. However, now it only
results in users making invalid bug reports because
they don't understand the feature ...

Examples during just the past 2 weeks: #3571 #3601 #3607

+   -  Removed **autoinit** configuration setting as it doesn't make sense to instantiate the database class but not connect to the database.
    -  Added subdrivers support (currently only used by PDO).
    -  Added an optional database name parameter to ``db_select()``.
    -  Removed ``protect_identifiers()`` and renamed internal method ``_protect_identifiers()`` to it instead - it was just an alias.

+The $config['global_xss_filtering'] setting
+===========================================
+
+As already explained above, XSS filtering should not be done on input data,
+but on output instead. Therefore, the ``$config['global_xss_filtering']``,
+which automatically filters *input* data, is considered a bad practice and
+is now deprecated.
+
+Instead, you should manually escape any user-provided data via the
+:php:func:`xss_clean()` function when you need to output it, or use a
+library like `HTML Purifier <http://htmlpurifier.org/>`_ that does that
+for you.

Subject: Fix #3627: Keep timed locks for more than 5 seconds

Emulated locks for Redis and Memcached now have a TTL
of 300 seconds (the default HTTP request timeout value
on many environments) and 30 attemps, each separated by
sleep(1), are made by the blocked request to try and
obtain a lock if it has been freed.

Additionaly, the blocking time for MySQL's locks,
which are also timed, is also set to 300 seconds.

 Encryption Library
 ##################
 
+.. important:: DO NOT use this or any other *encryption* library for
+	user password storage! Passwords must be *hashed* instead, and you
+	should do that via PHP's own `Password Hashing extension
+	<http://php.net/password>`_.

 The Encryption Library provides two-way data encryption. To do so in
 a cryptographically secure way, it utilizes PHP extensions that are
 unfortunately not always available on all systems.

Subject: Fixed bugs in form_validation for methods matches, differs, and
 valid_base64. Implemented tests for valid and invalid inputs for all basic
 rules available for form_validation. The invalid input data currently doesn't
 pass all tests.

 For example, when a call is made to:
 
-	http&#58;//example.com/news/latest/10
+	http://example.com/news/latest/10
 
 We might imagine that there is a controller named "news". The method
 being called on news would be "latest". The news method's job could be to
 grab 10 news items, and render them on the page. Very often in MVC,
 you'll see URL patterns that match:
 
-	http&#58;//example.com/[controller-class]/[controller-method]/[arguments]
+	http://example.com/[controller-class]/[controller-method]/[arguments]
 
 As URL schemes become more complex, this may change. But for now, this
 is all we will need to know.

Subject: Bug Fix manually delete caching method
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

According to documentation, to manually delete cache for page "/foo/bar" we should run $this->output->delete_cache('/foo/bar'), but in this case MD5 hash will be calculated for "http://site.com//foo/bar" and this is why, we should pass $uri without beginning slash (ie, "foo/bar"). But the problem is that there is no way to delete cache for home page because:
1) $this->output->delete_cache('/') — MD5 hash will be calculated for "http://site.com//" and cache file will not be deleted.
2) $this->output->delete_cache('') — MD5 hash will be calculated for "http://site.com/%CURRENT_PAGE%" and again, cache file will not be deleted.

Trimming the beginning slash, we enable ability to delete cache for home page by calling $this->output->delete_cache('/'). Also, this method will work as specified in the documentation.

Subject: Improve Cache Query String behaviour
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Typically, in most cases, we do not need to cache all the Query String variables. That's why I suggest to improve `Cache Include Query String` behaviour — allow the developer to independently specify which variables should be cached.

For example, consider a query to the following URL address:
http://site.com/search?q=query&page=2&session=abcd&utm_source=web

In this case we don't need to build md5 hash for entire query string, because `session` or `utm_source` can be different for all users. The only variables which should be used for md5 hash should be `q` and `page`. Thus, in `config.php` we can use `$config['cache_query_string'] = array('page', 'q');`.

So:
`$config['cache_query_string'] = FALSE;` → Cache Include Query String is disabled
`$config['cache_query_string'] = TRUE;` → Cache Include Query String is enabled for all
`$config['cache_query_string'] = array('page', 'q');` → enabled only for specified variables

Subject: Fixed bug - using field_data() on Oracle databases

When you're using oracle databases and want to retrieve column information through the function field_data($table) you get the following notice:

- Notice: Undefined property: stdClass::$COLUMN_DEFAULT in system/database/drivers/oci8/oci8_driver.php on line 576;

This happens because the oci8 driver tries to access a property that does not exist on query used to get field information. Checking the code we see a small validation to set default value, but the variable $default is not used. So we fix this bug by simply changing:

$retval[$i]->default = $query[$i]->COLUMN_DEFAULT;
to
$retval[$i]->default = $default;

Bug fixed. No more notices and the properly value is set.

Subject: Updated the MySQLi driver to provide support for SSL connections as
 well as additional database connection options. Uses the DB_driver class
 encrypt option as the flag for turning on encryption. Also added SSL
 connection validation with error logging in order to provide users a way to
 know if they are actually connecting via SSL.

Subject: Remove superfluous *Best Practices* parenthetical

In the documentation at user_guide/general/security.html#best-practices, the 3-item list has a superfluous parenthetical that is also misplaced.

This parenthetical currently is at the end of the first list item, though it refers to a step that can replace the first item. As per narfbg's request in PR https://github.com/bcit-ci/CodeIgniter/pull/3915, this change removes the parenthetical entirely.

The change is:

BEFORE:
#. Validate the data to ensure it conforms to the correct type, length,
size, etc. (sometimes this step can replace step one)
#. Filter the data as if it were tainted.
#. Escape the data before submitting it into your database or outputting
it to a browser.

AFTER:
#. Validate the data to ensure it conforms to the correct type, length,
size, etc.
#. Filter the data as if it were tainted.
#. Escape the data before submitting it into your database or outputting
it to a browser.

Subject: Fix an internal bug in QB where() escaping

string values passed to where() or having() aren't escaped. That's wrong
because escape-disabling should only be possible for identifiers and not
values.

+
+Replace all files and directories in your *system/* directory.
+
+.. note:: If you have any custom developed files in these directories,
+	please make copies of them first.
+
+Step 2: Update your CLI error templates
+=======================================
+
+Replace all files under your *application/errors/cli/* directory.

Subject: Failed security check

The implemented security check to make sure the path is NOT a URL can easily be bypassed (gives false negative) for all subdomains.
Eg "subdomain.domain.com" should ideally show an error but it does not.

The new security check tries to make a fsockopen connection to validate whether the URL is external or not.

+*********************
+Custom Result Objects
+*********************
+
+You can have the results returned as an instance of a custom class instead of a stdClass or array,
+as the ``result()`` and ``result_array()`` methods allow.This requires that the class is already
+loaded into memory. The class will have all values returned from the database set on the class
+as class variables. If your class already has those class variables created and ``protected`` then
+you should provide a ``__set()`` method to allow the class variables to be set.
+
+Example::
+
+	class User {
+		protected $id;
+		protected $email;
+		protected $username;
+		protected $last_login;
+
+		public function last_login($format)
+		{
+			return date($format, $this->last_login);
+		}
+
+		public function __set($name, $value)
+		{
+			$allowed_vars = array('id', 'email', 'username');
+
+			if (in_array($allowed_vars, $name)
+			{
+				$this->$name = $value;
+			}
+		}
+
+		public function __get($name)
+		{
+			if (isset($this->$name))
+			{
+				return $this->$name;
+			}
+		}
+	}
+
+In addition to the two methods listed below, the following methods also can take a class name
+to return the results as: ``first_row()``, ``last_row()``, ``next_row()``, and ``previous_row()``.
+
+**custom_result_object()**
+
+Returns the entire result set as an array of instances of the class requested. The only parameter
+is the name of the class to instantiate.
+
+Example::
+
+	$query = $this->db->query("YOUR QUERY");
+
+	if ($query->num_rows() > 0)
+	{
+		foreach ($query->custom_result_object('User') as $row)
+		{
+			echo $row->id;
+			echo $row->email;
+			echo $row->last_login('Y-m-d');
+		}
+	}
+
+**custom_row_object()**
+
+Returns a single row from your query results. The first parameter is the row number of the results.
+The second parameter is the class name to instantiate.
+
+Example::
+
+	$query = $this->db->query("YOUR QUERY");
+
+	if ($query->num_rows() > 0)
+	{
+		$row = $query->custom_row_object(0, 'User);
+
+		echo $row->email;   // access attributes
+		echo $row->last_login('Y-m-d');   // access class methods
+	}
+
+You can also use the ``row()`` method in exactly the same way.
+
+Example::
+
+	$row = $query->custom_row_object(0, 'User);

Subject: IP checking false positives and no ipv6 check

The currently implemented method marks all IPs between 0.0.0.0 - 999.999.999.999 as valid IP Address. Which generates false positives as any IP after 255.255.255.255 is not a valid IP address.

Also, there is no check for IPv6 IP addresses.

filter_var() solves both the issues.

Subject: Fix #4052

The bug actually had two instances:
- Callback routes with literal matches and HTTP verbs has never worked
- The reported issue in #4052, which is a regression introduced in 3.0.1
  with abc299b3a234eb7da1b7e3d257b7eba2da649219

Removed the literal matches logic altogether to avoid similar issues
in the future and reduce code complexity. The same logic is performed
with the regular expressions logic.

Subject: Refactor 'evil attributes' sanitization logic

Turned out pretty much impossible to do remove 'evil attributes'
with just one pattern - it either breaks something else, hits
pcre.backtrack_limit or causes PHP to segfault.

No benchmarks made, but there shouldn't be any performance
regressions since we're now trying to strip attributes only
after it is determined that they are inside a tag; up until
now this was done seprately for _sanitize_naughty_html()
and _remove_evil_attributes().

+When ``$config['base_url']`` is not set, CodeIgniter tries to automatically

+
+Auto-detection is never reliable and also has security implications, which

+
+One of the changes in CodeIgniter 3.0.3 is how this auto-detection works,

+of the hostname requested by the client. Therefore, if you've ever relied
+on auto-detection, it will change how your website works now.
+
+In case you need to allow e.g. multiple domains, or both http:// and
+https:// prefixes to be dynamically used depending on the request,
+remember that *application/config/config.php* is still a PHP script, in
+which you can create this logic with a few lines of code. For example::
+
+	$allowed_domains = array('domain1.tld', 'domain2.tld');

Subject: Respect $config['cur_page'] variable for pagination

After upgrading to CI3 I noticed that developers are able to determine the current page counter for pagination based on

* Explicit query string parameters
* URI segment configuration

In earlier versions a developer could still set the current page counter in the pagination lib directly which is useful if you want to use pagination with HTTP POST instead of GET. This could be done by passing

    $config['cur_page']  = '10';

to the pagination function for link generation. Currently this code has changed and will always try to check whether the uri segment is a valid number or not, even if the cur_page variable was passed in the associative array, and fallback to zero if it fails to validate that result.

This can be easily resolved by checking whether the counter was already set with a valid number from the $config array before trying to resolve it from the uri segment.

This fix give a developer more flexibility and stop CI from overwriting the externally set value with an incorrect one.

+Step 2: Remove 'prep_for_form' usage (deprecation)
+==================================================
+
+The :doc:`Form Validation Library <../libraries/form_validation>` has a
+``prep_for_form()`` method, which is/can also be used as a rule in
+``set_rules()`` to automatically perform HTML encoding on input data.
+
+Automatically encoding input (instead of output) data is a bad practice in
+the first place, and CodeIgniter and PHP itself offer other alternatives
+to this method anyway.
+For example, :doc:`Form Helper <../helpers/form_helper>` functions will
+automatically perform HTML escaping when necessary.
+
+Therefore, the *prep_for_form* method/rule is pretty much useless and is now
+deprecated and scheduled for removal in 3.1+.
+
+.. note:: The method is still available, but you're strongly encouraged to
+	remove its usage sooner rather than later.

+Step 2: Update your index.php file (optional)
+=============================================

+We've made some tweaks to the index.php file, mostly related to proper

+Form Validation method prep_for_form()
+======================================
+
+The :doc:`Form Validation Library <../libraries/form_validation>` has a
+``prep_for_form()`` method, which is/can also be used as a rule in
+``set_rules()`` to automatically perform HTML encoding on input data.
+
+Automatically encoding input (instead of output) data is a bad practice in
+the first place, and CodeIgniter and PHP itself offer other alternatives
+to this method anyway.
+For example, :doc:`Form Helper <../helpers/form_helper>` functions will
+automatically perform HTML escaping when necessary.
+
+Therefore, the *prep_for_form* method/rule is pretty much useless and is now
+deprecated and scheduled for removal in 3.1+.
+
+.. note:: The method is still available, but you're strongly encouraged to
+	remove its usage sooner rather than later.

 .. note:: If you have any custom developed files in these directories,
 	please make copies of them first.
+
+Step 2: Update your "ci_sessions" database table
+================================================
+
+If you're using the :doc:`Session Library </libraries/sessions>` with the
+'database' driver, you may have to ``ALTER`` your sessions table for your
+sessions to continue to work.
+
+.. note:: The table in question is not necessarily named "ci_sessions".
+	It is what you've set as your ``$config['sess_save_path']``.
+
+This will only affect you if you've changed your ``session.hash_function``
+*php.ini* setting to something like 'sha512'. Or if you've been running
+an older CodeIgniter version on PHP 7.1+.
+
+It is recommended that you do this anyway, just to avoid potential issues
+in the future if you do change your configuration.
+
+Just execute the one of the following SQL queries, depending on your
+database::
+
+	// MySQL:
+	ALTER TABLE ci_sessions CHANGE id id varchar(128) NOT NULL;
+
+	// PostgreSQL
+	ALTER TABLE ci_sessions ALTER COLUMN id SET DATA TYPE varchar(128);

+
+The :doc:`Date Helper <../helpers/date_helper>` function ``nice_date()`` is

+
+You can replace it with the following:

+Thus, ``nice_date()`` is now deprecated and scheduled for removal in
+CodeIgniter 3.2+.
+
+.. note:: The function is still available, but you're strongly encouraged
+	to remove its usage sooner rather than later.

-# CodeIgniter Unit Tests #
-
-Status : [![Build Status](https://secure.travis-ci.org/bcit-ci/CodeIgniter.png?branch=develop)](http://travis-ci.org/bcit-ci/CodeIgniter)
-
-### Introduction:
-
-This is the preliminary CodeIgniter testing documentation. It
-will cover both internal as well as external APIs and the reasoning
-behind their implementation, where appropriate. As with all CodeIgniter
-documentation, this file should maintain a mostly human readable
-format to facilitate clean api design. [see http://arrenbrecht.ch/testing/]
-
-*First public draft: everything is subject to change*
-
-### Requirements
-
-PHP Unit >= 3.5.6
-
-	pear channel-discover pear.phpunit.de
-	pear channel-discover pear.symfony.com
-	pear install phpunit/PHPUnit
-
-vfsStream
-
-	pear channel-discover pear.bovigo.org
-	pear install bovigo/vfsStream-beta
-
-#### Installation of PEAR and PHPUnit on Ubuntu
-
-  Installation on Ubuntu requires a few steps. Depending on your setup you may
-  need to use 'sudo' to install these. Mileage may vary but these steps are a
-  good start.
-
-	# Install the PEAR package
-	sudo apt-get install php-pear
-
-	# Add a few sources to PEAR
-	pear channel-discover pear.phpunit.de
-	pear channel-discover pear.symfony-project.com
-	pear channel-discover components.ez.no
-	pear channel-discover pear.bovigo.org
-
-	# Finally install PHPUnit and vfsStream (including dependencies)
-	pear install --alldeps phpunit/PHPUnit
-	pear install --alldeps bovigo/vfsStream-beta
-
-	# Finally, run 'phpunit' from within the ./tests directory
-	# and you should be on your way!
-
-## Test Suites:
-
-CodeIgniter bootstraps a request very directly, with very flat class
-hierarchy. As a result, there is no main CodeIgniter class until the
-controller is instantiated.
-
-This has forced the core classes to be relatively decoupled, which is
-a good thing. However, it makes that portion of code relatively hard
-to test.
-
-Right now that means we'll probably have two core test suites, along
-with a base for application and package tests. That gives us:
-
-1. Bootstrap Test	- test common.php and sanity check codeigniter.php [in planning]
-2. System Test		- test core components in relative isolation [in development]
-3. Application Test	- bootstrapping for application/tests [not started]
-4. Package Test		- bootstrapping for <package>/tests [not started]
-
-### Test Environment:
-
-The test/Bootstrap.php file establishes global constants such as BASEPATH,
-APPPATH, and VIEWPATH, initializing them to point to VFS locations. The
-test case class employs vfsStream to make a clean virtual filesystem with
-the necessary paths for every individual test.
-
-Within each test case, VFS directory objects are available to use as arguments
-to the VFS convenience functions (see below):
-
-- ci_vfs_root: VFS filesystem root
-- ci_app_root: Application directory
-- ci_base_root: System directory
-- ci_view_root: Views directory
-
-Classes being instantiated for testing are read from the actual filesystem
-by the unit test autoloader, as are mockups created in tests/mocks. If you
-need access to the real system directory, the SYSTEM_PATH constant always
-points to it.
-
-Any other resources which need to be read from the path constants must be
-created or cloned within your test. Functions for doing so are outlined
-below.
-
-### CI_TestCase Documentation
-
-Test cases should extend CI_TestCase. This internally extends
-PHPUnit\_Framework\_TestCase, so you have access to all of your
-usual PHPUnit methods.
-
-We need to provide a simple way to modify the globals and the
-common function output. We also need to be able to mock up
-the super object as we please.
-
-Current API is *not stable*. Names and implementations will change.
-
-    $this->ci_set_config($key, $val)
-
-Set the global config variables in a mock Config object. If key is an array,
-it will replace the entire config array. They are _not_ merged. If called
-without any parameters, it will create the mock object but not set any values.
-The mock Config object also provides rudimentary item() and load() stubs for
-delivering configured values to classes being tested and handling config load
-calls, respectively. The load() stub does _not_ actually load any files, it
-only records the filename provided. Check the config->loaded array to verify
-calls made.
-
-    $this->ci_instance($obj)
-
-Set the object to use as the "super object", in a lot
-of cases this will be a simple stdClass with the attributes
-you need it to have. If no parameter, will return the instance.
-
-	$this->ci_instance_var($name, $val)
-
-Add an attribute to the super object. This is useful if you
-set up a simple instance in setUp and then need to add different
-class mockups to your super object.
-
-	$this->ci_core_class($name)
-
-Get the _class name_ of a core class, so that you can instantiate
-it. The variable is returned by reference and is tied to the correct
-$GLOBALS key. For example:
-    
-	$cfg =& $this->ci_core_class('cfg'); // returns 'CI_Config'
-    $cfg = new $cfg; // instantiates config and overwrites the CFG global
-
-	$this->ci_set_core_class($name, $obj)
-
-An alternative way to set one of the core globals.
-
-	$this->ci_vfs_mkdir($name, $root)
-
-Creates a new directory in the test VFS. Pass a directory object to be the
-parent directory or none to create a root-level directory. Returns the new
-directory object.
-
-	$this->ci_vfs_create($file, $content, $root, $path)
-
-Creates a new VFS file. '.php' is automatically appended to the filename if
-it has no extension. Pass a directory object as the root, and an optional path
-to recurse and/or create for containing the file. Path may be a string (such
-as 'models/subdir') or an array (e.g. - array('models', 'subdir') ). Existing
-directories in the VFS root will be recursed until a new directory is
-identified - all others in the path will be created, so you can mix-and-match
-old and new directories. If $file is an array (key = name, value = content),
-multiple files will be created in the same path.
-
-	$this->ci_vfs_clone($path)
-
-Clones an existing file from the real filesystem to exist in the same path of
-the VFS. Path must be relative to the project root (i.e. - starting with
-'system' or 'application').
-
-	$this->ci_vfs_path($path, $base)
-
-Creates a VFS file path string suitable for use with PHP file operations. Path
-may be absolute from the VFS root, or relative to a base path. It is often
-useful to use APPPATH or BASEPATH as the base.
-
-	$this->helper($name)
-
-Loads a helper from the real filesystem.
-
-	$this->lang($name)
-
-Loads a language file from the real filesystem and returns the $lang array.
-
-	$this->ci_get_config()  __internal__
-
-Returns the global config array. Internal as you shouldn't need to
-call this (you're setting it, after all). Used internally to make
-CI's get_config() work.
-
-	CI_TestCase::instance()  __internal__
-
-Returns an instance of the current test case. We force phpunit to
-run with backup-globals enabled, so this will always be the instance
-of the currently running test class.
-
-### Going forward
-
-#### 1. Bootstrap Test
-
-Testing common.php should be pretty simple. Include the file, and test the
-functions. May require some tweaking so that we can grab the statics from all
-methods (see is_loaded()). Testing the actual CodeIgniter.php file will most
-likely be an output test for the default view, with some object checking after
-the file runs. Needs consideration.
-
-#### 2. System Test
-
-Testing the core system relies on being able to isolate the core components
-as much as possible. A few of them access other core classes as globals. These
-should be mocked up and easy to manipulate.
-
-All functions in common.php should be a minimal implementation, or and mapped
-to a method in the test's parent class to gives us full control of their output.
-
-#### 3. Application Test:
-
-Not sure yet, needs to handle:
-
-- Libraries
-- Helpers
-- Models
-- MY_* files
-- Controllers (uh...?)
-- Views? (watir, selenium, cucumber?)
-- Database Testing
-
-#### 4. Package Test:
-
-I don't have a clue how this will work.
-
-Needs to be able to handle packages
-that are used multiple times within the application (i.e. EE/Pyro modules)
-as well as packages that are used by multiple applications (library distributions)

+An incompatibility in PHP versions &lt; 5.2.3 and MySQL &lt; 5.0.7 with
+<em>mysql_set_charset()</em> creates a situation where using multi-byte
+character sets on these environments may potentially expose a SQL
+injection attack vector. Latin-1, UTF-8, and other &#8220;low ASCII&#8221;
+character sets are unaffected on all environments.</p>
+<p>If you are running or considering running a multi-byte character

+vulnerable.</p>

+<li>Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
+has been converted to a Helper and
+<a class="reference internal" href="helpers/captcha_helper.html"><em>documented</em></a>. The JavaScript

+controller sub-directory can be specified when running _GET
+strings instead of URI segments.</li>

+Loader and Config classes should try to look first for a requested

+<ul class="simple">
+<li>Added support for <a class="reference internal" href="general/models.html"><em>Models</em></a>.</li>
+<li>Redesigned the database libraries to support additional RDBMs
+(Postgres, MySQLi, etc.).</li>
+<li>Redesigned the <a class="reference internal" href="database/query_builder.html"><em>Active Record class</em></a>

+advanced features like JOINs.</li>
+<li>Added a feature to the database class that lets you run <a class="reference internal" href="database/call_function.html"><em>custom
+function calls</em></a>.</li>
+<li>Added support for <a class="reference internal" href="general/controllers.html"><em>private functions</em></a> in your

+<li>Removed slashing from the input class. After much debate we decided
+to kill this feature.</li>
+<li>Change the commenting style in the scripts to the PEAR standard so
+that IDEs and tools like phpDocumenter can harvest the comments.</li>
+<li>Added better class and function name-spacing to avoid collisions with
+user developed classes. All CodeIgniter classes are now prefixed with
+CI_ and all controller methods are prefixed with _ci to avoid
+controller collisions. A list of reserved function names can be
+<a class="reference internal" href="general/controllers.html"><em>found here</em></a>.</li>
+<li>Redesigned how the &#8220;CI&#8221; super object is referenced, depending on
+whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
+way to manage objects that utilizes a bit less resources.</li>
+<li>Deprecated: $this-&gt;db-&gt;use_table() has been deprecated. Please read

+<p>CodeIgniter is a community driven project and accepts contributions of code
+and documentation from the community. These contributions are made in the form
+of Issues or <a class="reference external" href="https://help.github.com/articles/using-pull-requests/">Pull Requests</a>
+on the <a class="reference external" href="https://github.com/bcit-ci/CodeIgniter">CodeIgniter repository</a> on GitHub.</p>
+<p>Issues are a quick way to point out a bug. If you find a bug or documentation
+error in CodeIgniter then please check a few things first:</p>
+<ul class="simple">
+<li>There is not already an open Issue</li>
+<li>The issue has already been fixed (check the develop branch, or look for
+closed Issues)</li>
+<li>Is it something really obvious that you fix it yourself?</li>
+</ul>
+<p>Reporting issues is helpful but an even better approach is to send a Pull
+Request, which is done by &#8220;Forking&#8221; the main repository and committing to your
+own copy. This will require you to use the version control system called Git.</p>
+<div class="section" id="support">
+<h2>Support<a class="headerlink" href="#support" title="Permalink to this headline">¶</a></h2>
+<p>Please note that GitHub is not for general support questions! If you are
+having trouble using a feature of CodeIgniter, ask for help on our
+<a class="reference external" href="http://forum.codeigniter.com/">forums</a> instead.</p>
+<p>If you are not sure whether you are using something correctly or if you
+have found a bug, again - please ask on the forums first.</p>
+</div>
+<div class="section" id="security">
+<h2>Security<a class="headerlink" href="#security" title="Permalink to this headline">¶</a></h2>
+<p>Did you find a security issue in CodeIgniter?</p>
+<p>Please <em>don&#8217;t</em> disclose it publicly, but e-mail us at <a class="reference external" href="mailto:security&#37;&#52;&#48;codeigniter&#46;com">security<span>&#64;</span>codeigniter<span>&#46;</span>com</a>,
+or report it via our page on <a class="reference external" href="https://hackerone.com/codeigniter">HackerOne</a>.</p>
+<p>If you&#8217;ve found a critical vulnerability, we&#8217;d be happy to credit you in our
+<cite>ChangeLog &lt;../changelog&gt;</cite>.</p>
+</div>
+<div class="section" id="tips-for-a-good-issue-report">
+<h2>Tips for a Good Issue Report<a class="headerlink" href="#tips-for-a-good-issue-report" title="Permalink to this headline">¶</a></h2>
+<p>Use a descriptive subject line (eg parser library chokes on commas) rather than a vague one (eg. your code broke).</p>
+<p>Address a single issue in a report.</p>
+<p>Identify the CodeIgniter version (eg 3.0-develop) and the component if you know it (eg. parser library)</p>
+<p>Explain what you expected to happen, and what did happen.
+Include error messages and stacktrace, if any.</p>
+<p>Include short code segments if they help to explain.
+Use a pastebin or dropbox facility to include longer segments of code or screenshots - do not include them in the issue report itself.
+This means setting a reasonable expiry for those, until the issue is resolved or closed.</p>
+<p>If you know how to fix the issue, you can do so in your own fork &amp; branch, and submit a pull request.
+The issue report information above should be part of that.</p>
+<p>If your issue report can describe the steps to reproduce the problem, that is great.
+If you can include a unit test that reproduces the problem, that is even better, as it gives whoever is fixing
+it a clearer target!</p>
+</div>
+<div class="section" id="guidelines">
+<h2>Guidelines<a class="headerlink" href="#guidelines" title="Permalink to this headline">¶</a></h2>
+<p>Before we look into how, here are the guidelines. If your Pull Requests fail
+to pass these guidelines it will be declined and you will need to re-submit
+when you’ve made the changes. This might sound a bit tough, but it is required
+for us to maintain quality of the code-base.</p>
+<div class="section" id="php-style">
+<h3>PHP Style<a class="headerlink" href="#php-style" title="Permalink to this headline">¶</a></h3>
+<p>All code must meet the <a class="reference external" href="https://codeigniter.com/userguide3/general/styleguide.html">Style Guide</a>, which is
+essentially the <a class="reference external" href="https://en.wikipedia.org/wiki/Indent_style#Allman_style">Allman indent style</a>, underscores and
+readable operators. This makes certain that all code is the same format as the
+existing code and means it will be as readable as possible.</p>
+</div>
+<div class="section" id="documentation">
+<h3>Documentation<a class="headerlink" href="#documentation" title="Permalink to this headline">¶</a></h3>
+<p>If you change anything that requires a change to documentation then you will
+need to add it. New classes, methods, parameters, changing default values, etc
+are all things that will require a change to documentation. The change-log
+must also be updated for every change. Also PHPDoc blocks must be maintained.</p>
+</div>
+<div class="section" id="compatibility">
+<h3>Compatibility<a class="headerlink" href="#compatibility" title="Permalink to this headline">¶</a></h3>
+<p>CodeIgniter recommends PHP 5.6 or newer to be used, but it should be
+compatible with PHP 5.3.7 so all code supplied must stick to this
+requirement. If PHP 5.4 (and above) functions or features are used then
+there must be a fallback for PHP 5.3.7.</p>
+</div>
+<div class="section" id="branching">
+<h3>Branching<a class="headerlink" href="#branching" title="Permalink to this headline">¶</a></h3>
+<p>CodeIgniter uses the <a class="reference external" href="http://nvie.com/posts/a-successful-git-branching-model/">Git-Flow</a> branching model
+which requires all pull requests to be sent to the &#8220;develop&#8221; branch. This is
+where the next planned version will be developed. The &#8220;master&#8221; branch will
+always contain the latest stable version and is kept clean so a &#8220;hotfix&#8221; (e.g:
+an emergency security patch) can be applied to master to create a new version,
+without worrying about other features holding it up. For this reason all
+commits need to be made to &#8220;develop&#8221; and any sent to &#8220;master&#8221; will be closed
+automatically. If you have multiple changes to submit, please place all
+changes into their own branch on your fork.</p>
+<p>One thing at a time: A pull request should only contain one change. That does
+not mean only one commit, but one change - however many commits it took. The
+reason for this is that if you change X and Y but send a pull request for both
+at the same time, we might really want X but disagree with Y, meaning we
+cannot merge the request. Using the Git-Flow branching model you can create
+new branches for both of these features and send two requests.</p>
+</div>
+<div class="section" id="signing">
+<h3>Signing<a class="headerlink" href="#signing" title="Permalink to this headline">¶</a></h3>
+<p>You must sign your work, certifying that you either wrote the work or
+otherwise have the right to pass it on to an open source project. git makes
+this trivial as you merely have to use <cite>&#8211;signoff</cite> on your commits to your
+CodeIgniter fork.</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span>git commit --signoff
+</pre></div>
+</div>
+<p>or simply</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span>git commit -s
+</pre></div>
+</div>
+<p>This will sign your commits with the information setup in your git config, e.g.</p>
+<blockquote>
+<div>Signed-off-by: John Q Public &lt;<a class="reference external" href="mailto:john&#46;public&#37;&#52;&#48;example&#46;com">john<span>&#46;</span>public<span>&#64;</span>example<span>&#46;</span>com</a>&gt;</div></blockquote>
+<p>If you are using Tower there is a &#8220;Sign-Off&#8221; checkbox in the commit window. You
+could even alias git commit to use the -s flag so you don’t have to think about
+it.</p>
+<p>By signing your work in this manner, you certify to a &#8220;Developer&#8217;s Certificate
+of Origin&#8221;. The current version of this certificate is in the <a class="reference internal" href="../DCO.html"><em>Developer&#8217;s Certificate of Origin 1.1</em></a> file
+in the root of this documentation.</p>

+<h2>Enabling Caching<a class="headerlink" href="#enabling-caching" title="Permalink to this headline">¶</a></h2>
+<p>Caching is enabled in three steps:</p>
+<ul class="simple">
+<li>Create a writable directory on your server where the cache files can
+be stored.</li>
+<li>Set the path to your cache folder in your
+application/config/database.php file.</li>
+<li>Enable the caching feature, either globally by setting the preference
+in your application/config/database.php file, or manually as
+described below.</li>
+</ul>
+<p>Once enabled, caching will happen automatically whenever a page is
+loaded that contains database queries.</p>
+</div>
+<div class="section" id="how-does-caching-work">
+<h2>How Does Caching Work?<a class="headerlink" href="#how-does-caching-work" title="Permalink to this headline">¶</a></h2>
+<p>CodeIgniter&#8217;s query caching system happens dynamically when your pages
+are viewed. When caching is enabled, the first time a web page is
+loaded, the query result object will be serialized and stored in a text
+file on your server. The next time the page is loaded the cache file
+will be used instead of accessing your database. Your database usage can
+effectively be reduced to zero for any pages that have been cached.</p>
+<p>Only read-type (SELECT) queries can be cached, since these are the only
+type of queries that produce a result. Write-type (INSERT, UPDATE, etc.)
+queries, since they don&#8217;t generate a result, will not be cached by the
+system.</p>
+<p>Cache files DO NOT expire. Any queries that have been cached will remain
+cached until you delete them. The caching system permits you clear
+caches associated with individual pages, or you can delete the entire
+collection of cache files. Typically you&#8217;ll want to use the housekeeping
+functions described below to delete cache files after certain events
+take place, like when you&#8217;ve added new information to your database.</p>
+</div>
+<div class="section" id="will-caching-improve-your-site-s-performance">
+<h2>Will Caching Improve Your Site&#8217;s Performance?<a class="headerlink" href="#will-caching-improve-your-site-s-performance" title="Permalink to this headline">¶</a></h2>
+<p>Getting a performance gain as a result of caching depends on many
+factors. If you have a highly optimized database under very little load,
+you probably won&#8217;t see a performance boost. If your database is under
+heavy use you probably will see an improved response, assuming your
+file-system is not overly taxed. Remember that caching simply changes
+how your information is retrieved, shifting it from being a database
+operation to a file-system one.</p>
+<p>In some clustered server environments, for example, caching may be
+detrimental since file-system operations are so intense. On single
+servers in shared environments, caching will probably be beneficial.
+Unfortunately there is no single answer to the question of whether you
+should cache your database. It really depends on your situation.</p>
+</div>
+<div class="section" id="how-are-cache-files-stored">
+<h2>How are Cache Files Stored?<a class="headerlink" href="#how-are-cache-files-stored" title="Permalink to this headline">¶</a></h2>
+<p>CodeIgniter places the result of EACH query into its own cache file.
+Sets of cache files are further organized into sub-folders corresponding
+to your controller functions. To be precise, the sub-folders are named
+identically to the first two segments of your URI (the controller class
+name and function name).</p>
+<p>For example, let&#8217;s say you have a controller called blog with a function
+called comments that contains three queries. The caching system will
+create a cache folder called blog+comments, into which it will write
+three cache files.</p>
+<p>If you use dynamic queries that change based on information in your URI
+(when using pagination, for example), each instance of the query will
+produce its own cache file. It&#8217;s possible, therefore, to end up with
+many times more cache files than you have queries.</p>
+</div>
+<div class="section" id="managing-your-cache-files">
+<h2>Managing your Cache Files<a class="headerlink" href="#managing-your-cache-files" title="Permalink to this headline">¶</a></h2>
+<p>Since cache files do not expire, you&#8217;ll need to build deletion routines
+into your application. For example, let&#8217;s say you have a blog that
+allows user commenting. Whenever a new comment is submitted you&#8217;ll want
+to delete the cache files associated with the controller function that
+serves up your comments. You&#8217;ll find two delete functions described
+below that help you clear data.</p>
+</div>
+<div class="section" id="not-all-database-functions-work-with-caching">
+<h2>Not All Database Functions Work with Caching<a class="headerlink" href="#not-all-database-functions-work-with-caching" title="Permalink to this headline">¶</a></h2>
+<p>Lastly, we need to point out that the result object that is cached is a
+simplified version of the full result object. For that reason, some of
+the query result functions are not available for use.</p>
+<p>The following functions ARE NOT available when using a cached result
+object:</p>
+<ul class="simple">
+<li>num_fields()</li>
+<li>field_names()</li>
+<li>field_data()</li>
+<li>free_result()</li>
+</ul>
+<p>Also, the two database resources (result_id and conn_id) are not
+available when caching, since result resources only pertain to run-time
+operations.</p>

+<p>Deletes the cache files associated with a particular page. This is

+<p>The caching system saves your cache files to folders that correspond to
+the URI of the page you are viewing. For example, if you are viewing a
+page at example.com/index.php/blog/comments, the caching system will put
+all cache files associated with it in a folder called blog+comments. To

+<h2>$this-&gt;db-&gt;call_function();<a class="headerlink" href="#this-db-call-function" title="Permalink to this headline">¶</a></h2>
+<p>This function enables you to call PHP database functions that are not
+natively included in CodeIgniter, in a platform independent manner. For
+example, let&#8217;s say you want to call the mysql_get_client_info()
+function, which is <strong>not</strong> natively supported by CodeIgniter. You could
+do so like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">call_function</span><span class="p">(</span><span class="s1">&#39;get_client_info&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>You must supply the name of the function, <strong>without</strong> the mysql_
+prefix, in the first parameter. The prefix is added automatically based
+on which database driver is currently being used. This permits you to
+run the same function on different database platforms. Obviously not all
+function calls are identical between platforms, so there are limits to
+how useful this function can be in terms of portability.</p>
+<p>Any parameters needed by the function you are calling will be added to
+the second parameter.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">call_function</span><span class="p">(</span><span class="s1">&#39;some_function&#39;</span><span class="p">,</span> <span class="nv">$param1</span><span class="p">,</span> <span class="nv">$param2</span><span class="p">,</span> <span class="nx">etc</span><span class="o">..</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Often, you will either need to supply a database connection ID or a
+database result ID. The connection ID can be accessed using:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">conn_id</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>The result ID can be accessed from within your result object, like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s2">&quot;SOME QUERY&quot;</span><span class="p">);</span>
+
+<span class="nv">$query</span><span class="o">-&gt;</span><span class="na">result_id</span><span class="p">;</span>
+</pre></div>

+<p>You can specify as many failovers as you like.</p>
+<p>The reason we use a multi-dimensional array rather than a more simple
+one is to permit you to optionally store multiple sets of connection
+values. If, for example, you run multiple environments (development,
+production, test, etc.) under a single installation, you can set up a
+connection group for each, then switch between groups as needed. For
+example, to set up a &#8220;test&#8221; environment you would do this:</p>

+<h2>Automatically Connecting<a class="headerlink" href="#automatically-connecting" title="Permalink to this headline">¶</a></h2>
+<p>The &#8220;auto connect&#8221; feature will load and instantiate the database class
+with every page load. To enable &#8220;auto connecting&#8221;, add the word database
+to the library array, as indicated in the following file:</p>
+<p>application/config/autoload.php</p>
+</div>
+<div class="section" id="manually-connecting">
+<h2>Manually Connecting<a class="headerlink" href="#manually-connecting" title="Permalink to this headline">¶</a></h2>
+<p>If only some of your pages require database connectivity you can
+manually connect to your database by adding this line of code in any
+function where it is needed, or in your class constructor to make the
+database available globally in that class.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">database</span><span class="p">();</span>

+<p>If the above function does <strong>not</strong> contain any information in the first

+file. For most people, this is the preferred method of use.</p>

+<ol class="arabic simple">
+<li>The database connection values, passed either as an array or a DSN
+string.</li>
+<li>TRUE/FALSE (boolean). Whether to return the connection ID (see

+<p>The first parameter of this function can <strong>optionally</strong> be used to
+specify a particular database group from your config file, or you can
+even submit connection values for a database that is not specified in
+your config file. Examples:</p>
+<p>To choose a specific group from your config file you can do this:</p>

+</pre></div>
+</div>
+<p>Where group_name is the name of the connection group from your config
+file.</p>
+<p>To connect manually to a desired database you can pass an array of

+<p>Takes a column or table name (optionally with an alias)
+and applies the configured <em>dbprefix</em> to it.</p>
+<p>Some logic is necessary in order to deal with
+column names that include the path.</p>
+<p>Consider a query like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">SELECT</span> <span class="o">*</span> <span class="nx">FROM</span> <span class="nx">hostname</span><span class="o">.</span><span class="nx">database</span><span class="o">.</span><span class="nx">table</span><span class="o">.</span><span class="nx">column</span> <span class="k">AS</span> <span class="nx">c</span> <span class="nx">FROM</span> <span class="nx">hostname</span><span class="o">.</span><span class="nx">database</span><span class="o">.</span><span class="nx">table</span>
+</pre></div>
+</div>
+<p>Or a query with aliasing:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">SELECT</span> <span class="nx">m</span><span class="o">.</span><span class="nx">member_id</span><span class="p">,</span> <span class="nx">m</span><span class="o">.</span><span class="nx">member_name</span> <span class="nx">FROM</span> <span class="nx">members</span> <span class="k">AS</span> <span class="nx">m</span>
+</pre></div>
+</div>
+<p>Since the column name can include up to four segments
+(host, DB, table, column) or also have an alias prefix,
+we need to do a bit of work to figure this out and
+insert the table prefix (if it exists) in the proper
+position, and escape only the correct identifiers.</p>
+<p>This method is used extensively by the Query Builder class.</p>

+<h3><a class="toc-backref" href="#id5">Adding fields</a><a class="headerlink" href="#adding-fields" title="Permalink to this headline">¶</a></h3>
+<p>Fields are created via an associative array. Within the array you must
+include a &#8216;type&#8217; key that relates to the datatype of the field. For

+<p>1. You can supply the table name and call it from the $this-&gt;db-&gt;
+object:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$fields</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">list_fields</span><span class="p">(</span><span class="s1">&#39;table_name&#39;</span><span class="p">);</span>

+<span class="p">}</span>
+</pre></div>
+</div>
+<p>2. You can gather the field names associated with any query you run by
+calling the function from your query result object:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s1">&#39;SELECT * FROM some_table&#39;</span><span class="p">);</span>
+
+<span class="k">foreach</span> <span class="p">(</span><span class="nv">$query</span><span class="o">-&gt;</span><span class="na">list_fields</span><span class="p">()</span> <span class="k">as</span> <span class="nv">$field</span><span class="p">)</span>
+<span class="p">{</span>
+        <span class="k">echo</span> <span class="nv">$field</span><span class="p">;</span>

+<p>Sometimes it&#8217;s helpful to know whether a particular field exists before

+</div>
+<p>If you have run a query already you can use the result object instead of

+<h3>Regular Queries<a class="headerlink" href="#regular-queries" title="Permalink to this headline">¶</a></h3>
+<p>To submit a query, use the <strong>query</strong> function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s1">&#39;YOUR QUERY HERE&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The query() function returns a database result <strong>object</strong> when &#8220;read&#8221;
+type queries are run, which you can use to <a class="reference internal" href="results.html"><em>show your
+results</em></a>. When &#8220;write&#8221; type queries are run it simply
+returns TRUE or FALSE depending on success or failure. When retrieving
+data you will typically assign the query to your own variable, like
+this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s1">&#39;YOUR QUERY HERE&#39;</span><span class="p">);</span>

+<div class="section" id="simplified-queries">
+<h3>Simplified Queries<a class="headerlink" href="#simplified-queries" title="Permalink to this headline">¶</a></h3>
+<p>The <strong>simple_query</strong> method is a simplified version of the
+$this-&gt;db-&gt;query() method. It DOES
+NOT return a database result set, nor does it set the query timer, or
+compile bind data, or store your query for debugging. It simply lets you
+submit a query. Most users will rarely use this function.</p>
+<p>It returns whatever the database drivers&#8217; &#8220;execute&#8221; function returns.
+That typically is TRUE/FALSE on success or failure for write type queries
+such as INSERT, DELETE or UPDATE statements (which is what it really
+should be used for) and a resource/object on success for queries with
+fetchable results.</p>

+<p>In many databases it is advisable to protect table and field names - for

+<p>This function will also add a table prefix to your table, assuming you

+<h2>Escaping Queries<a class="headerlink" href="#escaping-queries" title="Permalink to this headline">¶</a></h2>
+<p>It&#8217;s a very good security practice to escape your data before submitting
+it into your database. CodeIgniter has three methods that help you do
+this:</p>
+<ol class="arabic">
+<li><p class="first"><strong>$this-&gt;db-&gt;escape()</strong> This function determines the data type so
+that it can escape only string data. It also automatically adds
+single quotes around the data so you don&#8217;t have to:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$sql</span> <span class="o">=</span> <span class="s2">&quot;INSERT INTO table (title) VALUES(&quot;</span><span class="o">.</span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">escape</span><span class="p">(</span><span class="nv">$title</span><span class="p">)</span><span class="o">.</span><span class="s2">&quot;)&quot;</span><span class="p">;</span>
+</pre></div>
+</div>
+</li>
+<li><p class="first"><strong>$this-&gt;db-&gt;escape_str()</strong> This function escapes the data passed to
+it, regardless of type. Most of the time you&#8217;ll use the above
+function rather than this one. Use the function like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$sql</span> <span class="o">=</span> <span class="s2">&quot;INSERT INTO table (title) VALUES(&#39;&quot;</span><span class="o">.</span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">escape_str</span><span class="p">(</span><span class="nv">$title</span><span class="p">)</span><span class="o">.</span><span class="s2">&quot;&#39;)&quot;</span><span class="p">;</span>
+</pre></div>
+</div>
+</li>
+<li><p class="first"><strong>$this-&gt;db-&gt;escape_like_str()</strong> This method should be used when
+strings are to be used in LIKE conditions so that LIKE wildcards
+(&#8216;%&#8217;, &#8216;_&#8217;) in the string are also properly escaped.</p>
+</li>
+</ol>

+<div class="admonition important">
+<p class="first admonition-title">Important</p>
+<p class="last">The <tt class="docutils literal"><span class="pre">escape_like_str()</span></tt> method uses &#8216;!&#8217; (exclamation mark)
+to escape special characters for <em>LIKE</em> conditions. Because this
+method escapes partial strings that you would wrap in quotes
+yourself, it cannot automatically add the <tt class="docutils literal"><span class="pre">ESCAPE</span> <span class="pre">'!'</span></tt>
+condition for you, and so you&#8217;ll have to manually do that.</p>
+</div>
+</div>
+<div class="section" id="query-bindings">
+<h2>Query Bindings<a class="headerlink" href="#query-bindings" title="Permalink to this headline">¶</a></h2>
+<p>Bindings enable you to simplify your query syntax by letting the system
+put the queries together for you. Consider the following example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$sql</span> <span class="o">=</span> <span class="s2">&quot;SELECT * FROM some_table WHERE id = ? AND status = ? AND author = ?&quot;</span><span class="p">;</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="nv">$sql</span><span class="p">,</span> <span class="k">array</span><span class="p">(</span><span class="mi">3</span><span class="p">,</span> <span class="s1">&#39;live&#39;</span><span class="p">,</span> <span class="s1">&#39;Rick&#39;</span><span class="p">));</span>
+</pre></div>
+</div>
+<p>The question marks in the query are automatically replaced with the
+values in the array in the second parameter of the query function.</p>
+<p>Binding also work with arrays, which will be transformed to IN sets:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$sql</span> <span class="o">=</span> <span class="s2">&quot;SELECT * FROM some_table WHERE id IN ? AND status = ? AND author = ?&quot;</span><span class="p">;</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="nv">$sql</span><span class="p">,</span> <span class="k">array</span><span class="p">(</span><span class="k">array</span><span class="p">(</span><span class="mi">3</span><span class="p">,</span> <span class="mi">6</span><span class="p">),</span> <span class="s1">&#39;live&#39;</span><span class="p">,</span> <span class="s1">&#39;Rick&#39;</span><span class="p">));</span>
+</pre></div>
+</div>
+<p>The resulting query will be:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">SELECT</span> <span class="o">*</span> <span class="nx">FROM</span> <span class="nx">some_table</span> <span class="nx">WHERE</span> <span class="nx">id</span> <span class="nx">IN</span> <span class="p">(</span><span class="mi">3</span><span class="p">,</span><span class="mi">6</span><span class="p">)</span> <span class="k">AND</span> <span class="nx">status</span> <span class="o">=</span> <span class="s1">&#39;live&#39;</span> <span class="k">AND</span> <span class="nx">author</span> <span class="o">=</span> <span class="s1">&#39;Rick&#39;</span>
+</pre></div>
+</div>
+<p>The secondary benefit of using binds is that the values are
+automatically escaped, producing safer queries. You don&#8217;t have to
+remember to manually escape data; the engine does it automatically for
+you.</p>

+<p>CodeIgniter gives you access to a Query Builder class. This pattern
+allows information to be retrieved, inserted, and updated in your
+database with minimal scripting. In some cases only one or two lines
+of code are necessary to perform a database action.
+CodeIgniter does not require that each database table be its own class
+file. It instead provides a more simplified interface.</p>
+<p>Beyond simplicity, a major benefit to using the Query Builder features
+is that it allows you to create database independent applications, since
+the query syntax is generated by each database adapter. It also allows
+for safer queries, since the values are escaped automatically by the
+system.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">If you intend to write your own queries you can disable this
+class in your database config file, allowing the core database library
+and adapter to utilize fewer resources.</p>

+<p>The following functions allow you to build SQL <strong>SELECT</strong> statements.</p>
+<p><strong>$this-&gt;db-&gt;get()</strong></p>
+<p>Runs the selection query and returns the result. Can be used by itself
+to retrieve all records from a table:</p>

+</pre></div>
+</div>
+<p>The second and third parameters enable you to set a limit and offset
+clause:</p>

+<span class="c1">// (in MySQL. Other databases have slightly different syntax)</span>
+</pre></div>
+</div>
+<p>You&#8217;ll notice that the above function is assigned to a variable named
+$query, which can be used to show the results:</p>

+</div>
+<p>Please visit the <a class="reference internal" href="results.html"><em>result functions</em></a> page for a full
+discussion regarding result generation.</p>
+<p><strong>$this-&gt;db-&gt;get_compiled_select()</strong></p>
+<p>Compiles the selection query just like <strong>$this-&gt;db-&gt;get()</strong> but does not <em>run</em>
+the query. This method simply returns the SQL query as a string.</p>
+<p>Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$sql</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">get_compiled_select</span><span class="p">(</span><span class="s1">&#39;mytable&#39;</span><span class="p">);</span>
+<span class="k">echo</span> <span class="nv">$sql</span><span class="p">;</span>
+
+<span class="c1">// Prints string: SELECT * FROM mytable</span>
+</pre></div>
+</div>
+<p>The second parameter enables you to set whether or not the query builder query
+will be reset (by default it will be reset, just like when using <cite>$this-&gt;db-&gt;get()</cite>):</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">limit</span><span class="p">(</span><span class="mi">10</span><span class="p">,</span><span class="mi">20</span><span class="p">)</span><span class="o">-&gt;</span><span class="na">get_compiled_select</span><span class="p">(</span><span class="s1">&#39;mytable&#39;</span><span class="p">,</span> <span class="k">FALSE</span><span class="p">);</span>
+
+<span class="c1">// Prints string: SELECT * FROM mytable LIMIT 20, 10</span>
+<span class="c1">// (in MySQL. Other databases have slightly different syntax)</span>
+
+<span class="k">echo</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">select</span><span class="p">(</span><span class="s1">&#39;title, content, date&#39;</span><span class="p">)</span><span class="o">-&gt;</span><span class="na">get_compiled_select</span><span class="p">();</span>

+<span class="c1">// Prints string: SELECT title, content, date FROM mytable LIMIT 20, 10</span>
+</pre></div>
+</div>
+<p>The key thing to notice in the above example is that the second query did not
+utilize <strong>$this-&gt;db-&gt;from()</strong> and did not pass a table name into the first
+parameter. The reason for this outcome is because the query has not been
+executed using <strong>$this-&gt;db-&gt;get()</strong> which resets values or reset directly
+using <strong>$this-&gt;db-&gt;reset_query()</strong>.</p>
+<p><strong>$this-&gt;db-&gt;get_where()</strong></p>
+<p>Identical to the above function except that it permits you to add a
+&#8220;where&#8221; clause in the second parameter, instead of using the db-&gt;where()
+function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">get_where</span><span class="p">(</span><span class="s1">&#39;mytable&#39;</span><span class="p">,</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;id&#39;</span> <span class="o">=&gt;</span> <span class="nv">$id</span><span class="p">),</span> <span class="nv">$limit</span><span class="p">,</span> <span class="nv">$offset</span><span class="p">);</span>

+<p><strong>$this-&gt;db-&gt;set()</strong></p>
+<p>This function enables you to set values for inserts or updates.</p>
+<p><strong>It can be used instead of passing a data array directly to the insert
+or update functions:</strong></p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">set</span><span class="p">(</span><span class="s1">&#39;name&#39;</span><span class="p">,</span> <span class="nv">$name</span><span class="p">);</span>

+all stored information is reset for the next call. With caching, you can
+prevent this reset, and reuse information easily.</p>
+<p>Cached calls are cumulative. If you make 2 cached select() calls, and
+then 2 uncached select() calls, this will result in 4 select() calls.
+There are three Caching functions available:</p>
+<p><strong>$this-&gt;db-&gt;start_cache()</strong></p>
+<p>This function must be called to begin caching. All Query Builder queries
+of the correct type (see below for supported queries) are stored for
+later use.</p>
+<p><strong>$this-&gt;db-&gt;stop_cache()</strong></p>
+<p>This function can be called to stop caching.</p>
+<p><strong>$this-&gt;db-&gt;flush_cache()</strong></p>
+<p>This function deletes all items from the Query Builder cache.</p>

+<p>The above method is an alias of <tt class="docutils literal"><span class="pre">result_object()</span></tt>.</p>

+<h1>Transactions<a class="headerlink" href="#transactions" title="Permalink to this headline">¶</a></h1>
+<p>CodeIgniter&#8217;s database abstraction allows you to use transactions with
+databases that support transaction-safe table types. In MySQL, you&#8217;ll
+need to be running InnoDB or BDB table types rather than the more common
+MyISAM. Most other database platforms support transactions natively.</p>
+<p>If you are not familiar with transactions we recommend you find a good
+online resource to learn about them for your particular database. The
+information below assumes you have a basic understanding of
+transactions.</p>
+<div class="section" id="codeigniter-s-approach-to-transactions">
+<h2>CodeIgniter&#8217;s Approach to Transactions<a class="headerlink" href="#codeigniter-s-approach-to-transactions" title="Permalink to this headline">¶</a></h2>
+<p>CodeIgniter utilizes an approach to transactions that is very similar to
+the process used by the popular database class ADODB. We&#8217;ve chosen that
+approach because it greatly simplifies the process of running
+transactions. In most cases all that is required are two lines of code.</p>
+<p>Traditionally, transactions have required a fair amount of work to
+implement since they demand that you keep track of your queries and
+determine whether to commit or rollback based on the success or failure
+of your queries. This is particularly cumbersome with nested queries. In
+contrast, we&#8217;ve implemented a smart transaction system that does all
+this for you automatically (you can also manage your transactions
+manually if you choose to, but there&#8217;s really no benefit).</p>
+</div>
+<div class="section" id="running-transactions">
+<h2>Running Transactions<a class="headerlink" href="#running-transactions" title="Permalink to this headline">¶</a></h2>
+<p>To run your queries using transactions you will use the
+$this-&gt;db-&gt;trans_start() and $this-&gt;db-&gt;trans_complete() functions as
+follows:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">trans_start</span><span class="p">();</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s1">&#39;AN SQL QUERY...&#39;</span><span class="p">);</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">query</span><span class="p">(</span><span class="s1">&#39;ANOTHER QUERY...&#39;</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>You can run as many queries as you want between the start/complete
+functions and they will all be committed or rolled back based on success
+or failure of any given query.</p>
+</div>
+<div class="section" id="strict-mode">
+<h2>Strict Mode<a class="headerlink" href="#strict-mode" title="Permalink to this headline">¶</a></h2>
+<p>By default CodeIgniter runs all transactions in Strict Mode. When strict
+mode is enabled, if you are running multiple groups of transactions, if
+one group fails all groups will be rolled back. If strict mode is
+disabled, each group is treated independently, meaning a failure of one
+group will not affect any others.</p>
+<p>Strict Mode can be disabled as follows:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">trans_strict</span><span class="p">(</span><span class="k">FALSE</span><span class="p">);</span>

+<h2>Managing Errors<a class="headerlink" href="#managing-errors" title="Permalink to this headline">¶</a></h2>
+<p>If you have error reporting enabled in your config/database.php file

+<p>CodeIgniter uses Sphinx to generate its documentation in a variety of formats,
+using reStructuredText to handle the formatting.  If you are familiar with
+Markdown or Textile, you will quickly grasp reStructuredText.  The focus is
+on readability and user friendliness.
+While they can be quite technical, we always write for humans!</p>
+<p>A local table of contents should always be included, like the one below.
+It is created automatically by inserting the following:</p>

+<p>Headings not only provide order and sections within a page, but they also
+are used to automatically build both the page and document table of contents.
+Headings are formed by using certain characters as underlines for a bit of
+text.  Major headings, like page titles and section headings also use
+overlines.  Other headings just use underlines, with the following hierarchy:</p>

+<h1>Alternate PHP Syntax for View Files<a class="headerlink" href="#alternate-php-syntax-for-view-files" title="Permalink to this headline">¶</a></h1>
+<p>If you do not utilize CodeIgniter&#8217;s <a class="reference internal" href="../libraries/parser.html"><em>template
+engine</em></a>, you&#8217;ll be using pure PHP in your
+View files. To minimize the PHP code in these files, and to make it
+easier to identify the code blocks it is recommended that you use PHPs
+alternative syntax for control structures and short tag echo statements.
+If you are not familiar with this syntax, it allows you to eliminate the
+braces from your code, and eliminate &#8220;echo&#8221; statements.</p>
+<div class="section" id="automatic-short-tag-support">
+<h2>Automatic Short Tag Support<a class="headerlink" href="#automatic-short-tag-support" title="Permalink to this headline">¶</a></h2>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">If you find that the syntax described in this page does not
+work on your server it might be that &#8220;short tags&#8221; are disabled in your
+PHP ini file. CodeIgniter will optionally rewrite short tags on-the-fly,
+allowing you to use that syntax even if your server doesn&#8217;t support it.
+This feature can be enabled in your <em>config/config.php</em> file.</p>
+</div>
+<p>Please note that if you do use this feature, if PHP errors are
+encountered in your <strong>view files</strong>, the error message and line number
+will not be accurately shown. Instead, all errors will be shown as
+<tt class="docutils literal"><span class="pre">eval()</span></tt> errors.</p>
+</div>
+<div class="section" id="alternative-echos">
+<h2>Alternative Echos<a class="headerlink" href="#alternative-echos" title="Permalink to this headline">¶</a></h2>
+<p>Normally to echo, or print out a variable you would do this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span> <span class="k">echo</span> <span class="nv">$variable</span><span class="p">;</span> <span class="cp">?&gt;</span>
+</pre></div>
+</div>
+<p>With the alternative syntax you can instead do it this way:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?=</span><span class="nv">$variable</span><span class="cp">?&gt;</span>
+</pre></div>
+</div>
+</div>
+<div class="section" id="alternative-control-structures">
+<h2>Alternative Control Structures<a class="headerlink" href="#alternative-control-structures" title="Permalink to this headline">¶</a></h2>
+<p>Controls structures, like if, for, foreach, and while can be written in
+a simplified format as well. Here is an example using <tt class="docutils literal"><span class="pre">foreach</span></tt>:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">ul</span><span class="o">&gt;</span>
+
+<span class="o">&lt;?</span><span class="nx">php</span> <span class="k">foreach</span> <span class="p">(</span><span class="nv">$todo</span> <span class="k">as</span> <span class="nv">$item</span><span class="p">)</span><span class="o">:</span> <span class="cp">?&gt;</span>
+
+        <span class="p">&lt;</span><span class="nt">li</span><span class="p">&gt;</span><span class="cp">&lt;?</span><span class="o">=</span><span class="nv">$item</span><span class="cp">?&gt;</span><span class="p">&lt;/</span><span class="nt">li</span><span class="p">&gt;</span>
+
+<span class="cp">&lt;?php</span> <span class="k">endforeach</span><span class="p">;</span> <span class="cp">?&gt;</span>
+
+<span class="p">&lt;/</span><span class="nt">ul</span><span class="p">&gt;</span>
+</pre></div>
+</div>
+<p>Notice that there are no braces. Instead, the end brace is replaced with
+<tt class="docutils literal"><span class="pre">endforeach</span></tt>. Each of the control structures listed above has a similar
+closing syntax: <tt class="docutils literal"><span class="pre">endif</span></tt>, <tt class="docutils literal"><span class="pre">endfor</span></tt>, <tt class="docutils literal"><span class="pre">endforeach</span></tt>, and <tt class="docutils literal"><span class="pre">endwhile</span></tt></p>
+<p>Also notice that instead of using a semicolon after each structure
+(except the last one), there is a colon. This is important!</p>
+<p>Here is another example, using <tt class="docutils literal"><span class="pre">if</span></tt>/<tt class="docutils literal"><span class="pre">elseif</span></tt>/<tt class="docutils literal"><span class="pre">else</span></tt>. Notice the colons:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span> <span class="k">if</span> <span class="p">(</span><span class="nv">$username</span> <span class="o">===</span> <span class="s1">&#39;sally&#39;</span><span class="p">)</span><span class="o">:</span> <span class="cp">?&gt;</span>

+        <span class="p">&lt;</span><span class="nt">h3</span><span class="p">&gt;</span>Hi Sally<span class="p">&lt;/</span><span class="nt">h3</span><span class="p">&gt;</span>

+<p>In some cases you may want to develop classes that exist apart from your

+
+<p><strong>Any class that you instantiate within your controller methods can
+access CodeIgniter&#8217;s native resources</strong> simply by using the
+<tt class="docutils literal"><span class="pre">get_instance()</span></tt> function. This function returns the main
+CodeIgniter object.</p>
+<p>Normally, to call any of the available methods, CodeIgniter requires
+you to use the <tt class="docutils literal"><span class="pre">$this</span></tt> construct:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">helper</span><span class="p">(</span><span class="s1">&#39;url&#39;</span><span class="p">);</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;session&#39;</span><span class="p">);</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;base_url&#39;</span><span class="p">);</span>
+<span class="c1">// etc.</span>
+</pre></div>
+</div>
+<p><tt class="docutils literal"><span class="pre">$this</span></tt>, however, only works within your controllers, your models,
+or your views. If you would like to use CodeIgniter&#8217;s classes from
+within your own custom classes you can do so as follows:</p>
+<p>First, assign the CodeIgniter object to a variable:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$CI</span> <span class="o">=&amp;</span> <span class="nx">get_instance</span><span class="p">();</span>
+</pre></div>
+</div>
+<p>Once you&#8217;ve assigned the object to a variable, you&#8217;ll use that variable
+<em>instead</em> of <tt class="docutils literal"><span class="pre">$this</span></tt>:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$CI</span> <span class="o">=&amp;</span> <span class="nx">get_instance</span><span class="p">();</span>
+
+<span class="nv">$CI</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">helper</span><span class="p">(</span><span class="s1">&#39;url&#39;</span><span class="p">);</span>
+<span class="nv">$CI</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;session&#39;</span><span class="p">);</span>
+<span class="nv">$CI</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;base_url&#39;</span><span class="p">);</span>
+<span class="c1">// etc.</span>
+</pre></div>
+</div>
+<p>If you&#8217;ll be using <tt class="docutils literal"><span class="pre">get_instance()</span></tt> inside another class, then it would
+be better if you assign it to a property. This way, you won&#8217;t need to call
+<tt class="docutils literal"><span class="pre">get_instance()</span></tt> in every single method.</p>
+<p>Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">Example</span> <span class="p">{</span>
+
+        <span class="k">protected</span> <span class="nv">$CI</span><span class="p">;</span>
+
+        <span class="c1">// We&#39;ll use a constructor, as you can&#39;t directly call a function</span>
+        <span class="c1">// from a property definition.</span>
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">__construct</span><span class="p">()</span>
+        <span class="p">{</span>
+                <span class="c1">// Assign the CodeIgniter super-object</span>
+                <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">CI</span> <span class="o">=&amp;</span> <span class="nx">get_instance</span><span class="p">();</span>
+        <span class="p">}</span>
+
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">foo</span><span class="p">()</span>
+        <span class="p">{</span>
+                <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">CI</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">helper</span><span class="p">(</span><span class="s1">&#39;url&#39;</span><span class="p">);</span>
+                <span class="nx">redirect</span><span class="p">();</span>
+        <span class="p">}</span>
+
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">bar</span><span class="p">()</span>
+        <span class="p">{</span>
+                <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">CI</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;base_url&#39;</span><span class="p">);</span>
+        <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>In the above example, both methods <tt class="docutils literal"><span class="pre">foo()</span></tt> and <tt class="docutils literal"><span class="pre">bar()</span></tt> will work
+after you instantiate the Example class, without the need to call
+<tt class="docutils literal"><span class="pre">get_instance()</span></tt> in each of them.</p>

+<p>CodeIgniter comes with an &#8220;Auto-load&#8221; feature that permits libraries,
+helpers, and models to be initialized automatically every time the
+system runs. If you need certain resources globally throughout your
+application you should consider auto-loading them for convenience.</p>
+<p>The following items can be loaded automatically:</p>
+<ul class="simple">
+<li>Classes found in the <em>libraries/</em> directory</li>
+<li>Helper files found in the <em>helpers/</em> directory</li>
+<li>Custom config files found in the <em>config/</em> directory</li>

+<h1>Web Page Caching<a class="headerlink" href="#web-page-caching" title="Permalink to this headline">¶</a></h1>
+<p>CodeIgniter lets you cache your pages in order to achieve maximum
+performance.</p>
+<p>Although CodeIgniter is quite fast, the amount of dynamic information
+you display in your pages will correlate directly to the server
+resources, memory, and processing cycles utilized, which affect your
+page load speeds. By caching your pages, since they are saved in their
+fully rendered state, you can achieve performance that nears that of
+static web pages.</p>
+<div class="section" id="how-does-caching-work">
+<h2>How Does Caching Work?<a class="headerlink" href="#how-does-caching-work" title="Permalink to this headline">¶</a></h2>
+<p>Caching can be enabled on a per-page basis, and you can set the length
+of time that a page should remain cached before being refreshed. When a
+page is loaded for the first time, the cache file will be written to
+your application/cache folder. On subsequent page loads the cache file
+will be retrieved and sent to the requesting user&#8217;s browser. If it has
+expired, it will be deleted and refreshed before being sent to the
+browser.</p>
+</div>
+<div class="section" id="enabling-caching">
+<h2>Enabling Caching<a class="headerlink" href="#enabling-caching" title="Permalink to this headline">¶</a></h2>
+<p>To enable caching, put the following tag in any of your controller
+methods:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">output</span><span class="o">-&gt;</span><span class="na">cache</span><span class="p">(</span><span class="nv">$n</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Where <tt class="docutils literal"><span class="pre">$n</span></tt> is the number of <strong>minutes</strong> you wish the page to remain
+cached between refreshes.</p>
+<p>The above tag can go anywhere within a method. It is not affected by
+the order that it appears, so place it wherever it seems most logical to
+you. Once the tag is in place, your pages will begin being cached.</p>
+<div class="admonition important">
+<p class="first admonition-title">Important</p>
+<p class="last">Because of the way CodeIgniter stores content for output,
+caching will only work if you are generating display for your
+controller with a <a class="reference internal" href="views.html"><em>view</em></a>.</p>
+</div>
+<div class="admonition important">
+<p class="first admonition-title">Important</p>
+<p class="last">If you change configuration options that might affect
+your output, you have to manually delete your cache files.</p>
+</div>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">Before the cache files can be written you must set the file
+permissions on your <em>application/cache/</em> directory such that
+it is writable.</p>
+</div>
+</div>
+<div class="section" id="deleting-caches">
+<h2>Deleting Caches<a class="headerlink" href="#deleting-caches" title="Permalink to this headline">¶</a></h2>
+<p>If you no longer wish to cache a file you can remove the caching tag and
+it will no longer be refreshed when it expires.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">Removing the tag will not delete the cache immediately. It will
+have to expire normally.</p>

+<p>The command-line interface is a text-based method of interacting with
+computers. For more information, check the <a class="reference external" href="http://en.wikipedia.org/wiki/Command-line_interface">Wikipedia
+article</a>.</p>

+<h2><a class="toc-backref" href="#id3">Why run via the command-line?</a><a class="headerlink" href="#why-run-via-the-command-line" title="Permalink to this headline">¶</a></h2>
+<p>There are many reasons for running CodeIgniter from the command-line,
+but they are not always obvious.</p>
+<ul class="simple">
+<li>Run your cron-jobs without needing to use <em>wget</em> or <em>curl</em></li>
+<li>Make your cron-jobs inaccessible from being loaded in the URL by
+checking the return value of <a class="reference internal" href="common_functions.html#is_cli" title="is_cli"><tt class="xref php php-func docutils literal"><span class="pre">is_cli()</span></tt></a>.</li>
+<li>Make interactive &#8220;tasks&#8221; that can do things like set permissions,
+prune cache folders, run backups, etc.</li>
+<li>Integrate with other applications in other languages. For example, a
+random C++ script could call one command and run code in your models!</li>
+</ul>
+</div>
+<div class="section" id="let-s-try-it-hello-world">
+<h2><a class="toc-backref" href="#id4">Let&#8217;s try it: Hello World!</a><a class="headerlink" href="#let-s-try-it-hello-world" title="Permalink to this headline">¶</a></h2>
+<p>Let&#8217;s create a simple controller so you can see it in action. Using your
+text editor, create a file called Tools.php, and put the following code
+in it:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span>
+<span class="k">class</span> <span class="nc">Tools</span> <span class="k">extends</span> <span class="nx">CI_Controller</span> <span class="p">{</span>
+
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">message</span><span class="p">(</span><span class="nv">$to</span> <span class="o">=</span> <span class="s1">&#39;World&#39;</span><span class="p">)</span>
+        <span class="p">{</span>
+                <span class="k">echo</span> <span class="s2">&quot;Hello </span><span class="si">{</span><span class="nv">$to</span><span class="si">}</span><span class="s2">!&quot;</span><span class="o">.</span><span class="nx">PHP_EOL</span><span class="p">;</span>
+        <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>Then save the file to your <em>application/controllers/</em> folder.</p>
+<p>Now normally you would visit the site using a URL similar to this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">tools</span><span class="o">/</span><span class="nx">message</span><span class="o">/</span><span class="nx">to</span>
+</pre></div>
+</div>
+<p>Instead, we are going to open the terminal in Mac/Linux or go to Run &gt; &#8220;cmd&#8221;
+in Windows and navigate to our CodeIgniter project.</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span>$ <span class="nb">cd</span> /path/to/project<span class="p">;</span>
+$ php index.php tools message
+</pre></div>
+</div>
+<p>If you did it right, you should see <em>Hello World!</em> printed.</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span>$ php index.php tools message <span class="s2">&quot;John Smith&quot;</span>
+</pre></div>
+</div>
+<p>Here we are passing it a argument in the same way that URL parameters
+work. &#8220;John Smith&#8221; is passed as a argument and output is:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">Hello</span> <span class="nx">John</span> <span class="nx">Smith</span><span class="o">!</span>
+</pre></div>
+</div>
+</div>
+<div class="section" id="that-s-it">
+<h2><a class="toc-backref" href="#id5">That&#8217;s it!</a><a class="headerlink" href="#that-s-it" title="Permalink to this headline">¶</a></h2>
+<p>That, in a nutshell, is all there is to know about controllers on the
+command line. Remember that this is just a normal controller, so routing
+and <tt class="docutils literal"><span class="pre">_remap()</span></tt> works fine.</p>

+<p><strong>A Controller is simply a class file that is named in a way that can be

+<p>In the above example, CodeIgniter would attempt to find a controller

+<p>Let&#8217;s create a simple controller so you can see it in action. Using your
+text editor, create a file called Blog.php, and put the following code
+in it:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span>

+<p>Then save the file to your <em>application/controllers/</em> directory.</p>
+<div class="admonition important">

+<h2><a class="toc-backref" href="#id10">Organizing Your Controllers into Sub-directories</a><a class="headerlink" href="#organizing-your-controllers-into-sub-directories" title="Permalink to this headline">¶</a></h2>
+<p>If you are building a large application you might want to hierarchically
+organize or structure your controllers into sub-directories. CodeIgniter
+permits you to do this.</p>
+<p>Simply create sub-directories under the main <em>application/controllers/</em>
+one and place your controller classes within them.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p>When using this feature the first segment of your URI must
+specify the folder. For example, let&#8217;s say you have a controller located
+here:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">application</span><span class="o">/</span><span class="nx">controllers</span><span class="o">/</span><span class="nx">products</span><span class="o">/</span><span class="nx">Shoes</span><span class="o">.</span><span class="nx">php</span>
+</pre></div>
+</div>
+<p>To call the above controller your URI will look something like this:</p>
+<div class="last highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">products</span><span class="o">/</span><span class="nx">shoes</span><span class="o">/</span><span class="nx">show</span><span class="o">/</span><span class="mi">123</span>
+</pre></div>
+</div>
+</div>
+<p>Each of your sub-directories may contain a default controller which will be
+called if the URL contains <em>only</em> the sub-directory. Simply put a controller
+in there that matches the name of your &#8216;default_controller&#8217; as specified in
+your <em>application/config/routes.php</em> file.</p>
+<p>CodeIgniter also permits you to remap your URIs using its <a class="reference internal" href="routing.html"><em>URI
+Routing</em></a> feature.</p>
+</div>
+<div class="section" id="class-constructors">
+<h2><a class="toc-backref" href="#id11">Class Constructors</a><a class="headerlink" href="#class-constructors" title="Permalink to this headline">¶</a></h2>
+<p>If you intend to use a constructor in any of your Controllers, you
+<strong>MUST</strong> place the following line of code in it:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">parent</span><span class="o">::</span><span class="na">__construct</span><span class="p">();</span>
+</pre></div>
+</div>
+<p>The reason this line is necessary is because your local constructor will
+be overriding the one in the parent controller class so we need to
+manually call it.</p>
+<p>Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span>
+<span class="k">class</span> <span class="nc">Blog</span> <span class="k">extends</span> <span class="nx">CI_Controller</span> <span class="p">{</span>
+
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">__construct</span><span class="p">()</span>
+        <span class="p">{</span>
+                <span class="k">parent</span><span class="o">::</span><span class="na">__construct</span><span class="p">();</span>
+                <span class="c1">// Your own constructor code</span>
+        <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>Constructors are useful if you need to set some default values, or run a
+default process when your class is instantiated. Constructors can&#8217;t
+return a value, but they can do some default work.</p>
+</div>
+<div class="section" id="reserved-method-names">
+<h2><a class="toc-backref" href="#id12">Reserved method names</a><a class="headerlink" href="#reserved-method-names" title="Permalink to this headline">¶</a></h2>
+<p>Since your controller classes will extend the main application
+controller you must be careful not to name your methods identically to
+the ones used by that class, otherwise your local functions will
+override them. See <a class="reference internal" href="reserved_names.html"><em>Reserved Names</em></a> for a full
+list.</p>
+<div class="admonition important">
+<p class="first admonition-title">Important</p>
+<p class="last">You should also never have a method named identically
+to its class name. If you do, and there is no <tt class="docutils literal"><span class="pre">__construct()</span></tt>
+method in the same class, then your e.g. <tt class="docutils literal"><span class="pre">Index::index()</span></tt>
+method will be executed as a class constructor! This is a PHP4
+backwards-compatibility feature.</p>
+</div>
+</div>
+<div class="section" id="that-s-it">
+<h2><a class="toc-backref" href="#id13">That&#8217;s it!</a><a class="headerlink" href="#that-s-it" title="Permalink to this headline">¶</a></h2>

+<h1>Creating Core System Classes<a class="headerlink" href="#creating-core-system-classes" title="Permalink to this headline">¶</a></h1>
+<p>Every time CodeIgniter runs there are several base classes that are
+initialized automatically as part of the core framework. It is possible,
+however, to swap any of the core system classes with your own versions
+or even extend the core versions.</p>
+<p><strong>Most users will never have any need to do this, but the option to
+replace or extend them does exist for those who would like to
+significantly alter the CodeIgniter core.</strong></p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">Messing with a core system class has a lot of implications, so
+make sure you know what you are doing before attempting it.</p>

+<div class="section" id="system-class-list">
+<h2>System Class List<a class="headerlink" href="#system-class-list" title="Permalink to this headline">¶</a></h2>
+<p>The following is a list of the core system files that are invoked every
+time CodeIgniter runs:</p>
+<ul class="simple">
+<li>Benchmark</li>
+<li>Config</li>
+<li>Controller</li>
+<li>Exceptions</li>

+<h2>Replacing Core Classes<a class="headerlink" href="#replacing-core-classes" title="Permalink to this headline">¶</a></h2>
+<p>To use one of your own system classes instead of a default one simply
+place your version inside your local <em>application/core/</em> directory:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">application</span><span class="o">/</span><span class="nx">core</span><span class="o">/</span><span class="nx">some_class</span><span class="o">.</span><span class="nx">php</span>
+</pre></div>
+</div>
+<p>If this directory does not exist you can create it.</p>
+<p>Any file named identically to one from the list above will be used
+instead of the one normally used.</p>
+<p>Please note that your class must use CI as a prefix. For example, if
+your file is named Input.php the class will be named:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">CI_Input</span> <span class="p">{</span>

+<p>If all you need to do is add some functionality to an existing library -
+perhaps add a method or two - then it&#8217;s overkill to replace the entire
+library with your version. In this case it&#8217;s better to simply extend the
+class. Extending a class is nearly identical to replacing a class with a
+couple exceptions:</p>
+<ul class="simple">
+<li>The class declaration must extend the parent class.</li>
+<li>Your new class name and filename must be prefixed with MY_ (this
+item is configurable. See below.).</li>
+</ul>
+<p>For example, to extend the native Input class you&#8217;ll create a file named
+application/core/MY_Input.php, and declare your class with:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">MY_Input</span> <span class="k">extends</span> <span class="nx">CI_Input</span> <span class="p">{</span>
+
+<span class="p">}</span>
+</pre></div>
+</div>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p>If you need to use a constructor in your class make sure you
+extend the parent constructor:</p>
+<div class="last highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">MY_Input</span> <span class="k">extends</span> <span class="nx">CI_Input</span> <span class="p">{</span>
+
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">__construct</span><span class="p">()</span>
+        <span class="p">{</span>
+                <span class="k">parent</span><span class="o">::</span><span class="na">__construct</span><span class="p">();</span>
+        <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+</div>
+<p><strong>Tip:</strong> Any functions in your class that are named identically to the
+methods in the parent class will be used instead of the native ones
+(this is known as &#8220;method overriding&#8221;). This allows you to substantially
+alter the CodeIgniter core.</p>
+<p>If you are extending the Controller core class, then be sure to extend
+your new class in your application controller&#8217;s constructors.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">Welcome</span> <span class="k">extends</span> <span class="nx">MY_Controller</span> <span class="p">{</span>
+
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">__construct</span><span class="p">()</span>
+        <span class="p">{</span>
+                <span class="k">parent</span><span class="o">::</span><span class="na">__construct</span><span class="p">();</span>

+        <span class="k">public</span> <span class="k">function</span> <span class="nf">index</span><span class="p">()</span>
+        <span class="p">{</span>
+                <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">view</span><span class="p">(</span><span class="s1">&#39;welcome_message&#39;</span><span class="p">);</span>

+</pre></div>
+</div>
+<div class="section" id="setting-your-own-prefix">

+<h1>Creating Libraries<a class="headerlink" href="#creating-libraries" title="Permalink to this headline">¶</a></h1>
+<p>When we use the term &#8220;Libraries&#8221; we are normally referring to the
+classes that are located in the libraries directory and described in the
+Class Reference of this user guide. In this case, however, we will
+instead describe how you can create your own libraries within your
+application/libraries directory in order to maintain separation between
+your local resources and the global framework resources.</p>
+<p>As an added bonus, CodeIgniter permits your libraries to extend native
+classes if you simply need to add some functionality to an existing
+library. Or you can even replace native libraries just by placing
+identically named versions in your <em>application/libraries</em> directory.</p>
+<p>In summary:</p>
+<ul class="simple">
+<li>You can create entirely new libraries.</li>
+<li>You can extend native libraries.</li>
+<li>You can replace native libraries.</li>
+</ul>
+<p>The page below explains these three concepts in detail.</p>
+<div class="admonition note">

+<p>Once loaded you can access your class using the lower case version:</p>

+<p>In the library loading method you can dynamically pass data as an

+<p>If you use this feature you must set up your class constructor to expect

+</pre></div>
+</div>
+<p>You can also pass parameters stored in a config file. Simply create a
+config file named identically to the class file name and store it in
+your <em>application/config/</em> directory. Note that if you dynamically pass
+parameters as described above, the config file option will not be

+<h2>Utilizing CodeIgniter Resources within Your Library<a class="headerlink" href="#utilizing-codeigniter-resources-within-your-library" title="Permalink to this headline">¶</a></h2>
+<p>To access CodeIgniter&#8217;s native resources within your library use the
+<tt class="docutils literal"><span class="pre">get_instance()</span></tt> method. This method returns the CodeIgniter super
+object.</p>
+<p>Normally from within your controller methods you will call any of the
+available CodeIgniter methods using the <tt class="docutils literal"><span class="pre">$this</span></tt> construct:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">helper</span><span class="p">(</span><span class="s1">&#39;url&#39;</span><span class="p">);</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;session&#39;</span><span class="p">);</span>

+<span class="c1">// etc.</span>
+</pre></div>
+</div>
+<p><tt class="docutils literal"><span class="pre">$this</span></tt>, however, only works directly within your controllers, your
+models, or your views. If you would like to use CodeIgniter&#8217;s classes
+from within your own custom classes you can do so as follows:</p>
+<p>First, assign the CodeIgniter object to a variable:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$CI</span> <span class="o">=&amp;</span> <span class="nx">get_instance</span><span class="p">();</span>
+</pre></div>
+</div>
+<p>Once you&#8217;ve assigned the object to a variable, you&#8217;ll use that variable
+<em>instead</em> of <tt class="docutils literal"><span class="pre">$this</span></tt>:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$CI</span> <span class="o">=&amp;</span> <span class="nx">get_instance</span><span class="p">();</span>
+
+<span class="nv">$CI</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">helper</span><span class="p">(</span><span class="s1">&#39;url&#39;</span><span class="p">);</span>
+<span class="nv">$CI</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;session&#39;</span><span class="p">);</span>
+<span class="nv">$CI</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;base_url&#39;</span><span class="p">);</span>
+<span class="c1">// etc.</span>
+</pre></div>
+</div>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p>You&#8217;ll notice that the above <tt class="docutils literal"><span class="pre">get_instance()</span></tt> function is being
+passed by reference:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$CI</span> <span class="o">=&amp;</span> <span class="nx">get_instance</span><span class="p">();</span>
+</pre></div>
+</div>
+<p class="last">This is very important. Assigning by reference allows you to use the
+original CodeIgniter object rather than creating a copy of it.</p>
+</div>
+<p>However, since a library is a class, it would be better if you
+take full advantage of the OOP principles. So, in order to

+<h2>Replacing Native Libraries with Your Versions<a class="headerlink" href="#replacing-native-libraries-with-your-versions" title="Permalink to this headline">¶</a></h2>
+<p>Simply by naming your class files identically to a native library will
+cause CodeIgniter to use it instead of the native one. To use this
+feature you must name the file and the class declaration exactly the
+same as the native library. For example, to replace the native Email
+library you&#8217;ll create a file named <em>application/libraries/Email.php</em>,
+and declare your class with:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">CI_Email</span> <span class="p">{</span>
+
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>Note that most native classes are prefixed with CI_.</p>
+<p>To load your library you&#8217;ll see the standard loading method:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;email&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">At this time the Database classes can not be replaced with
+your own versions.</p>

+<div class="section" id="extending-native-libraries">
+<h2>Extending Native Libraries<a class="headerlink" href="#extending-native-libraries" title="Permalink to this headline">¶</a></h2>
+<p>If all you need to do is add some functionality to an existing library -
+perhaps add a method or two - then it&#8217;s overkill to replace the entire
+library with your version. In this case it&#8217;s better to simply extend the
+class. Extending a class is nearly identical to replacing a class with a
+couple exceptions:</p>
+<ul class="simple">
+<li>The class declaration must extend the parent class.</li>
+<li>Your new class name and filename must be prefixed with MY_ (this
+item is configurable. See below.).</li>
+</ul>
+<p>For example, to extend the native Email class you&#8217;ll create a file named
+<em>application/libraries/MY_Email.php</em>, and declare your class with:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">MY_Email</span> <span class="k">extends</span> <span class="nx">CI_Email</span> <span class="p">{</span>
+
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>If you need to use a constructor in your class make sure you
+extend the parent constructor:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">MY_Email</span> <span class="k">extends</span> <span class="nx">CI_Email</span> <span class="p">{</span>
+
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">__construct</span><span class="p">(</span><span class="nv">$config</span> <span class="o">=</span> <span class="k">array</span><span class="p">())</span>
+        <span class="p">{</span>
+                <span class="k">parent</span><span class="o">::</span><span class="na">__construct</span><span class="p">(</span><span class="nv">$config</span><span class="p">);</span>
+        <span class="p">}</span>
+
+<span class="p">}</span>
+</pre></div>
+</div>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">Not all of the libraries have the same (or any) parameters
+in their constructor. Take a look at the library that you&#8217;re
+extending first to see how it should be implemented.</p>
+</div>
+<div class="section" id="loading-your-sub-class">
+<h3>Loading Your Sub-class<a class="headerlink" href="#loading-your-sub-class" title="Permalink to this headline">¶</a></h3>
+<p>To load your sub-class you&#8217;ll use the standard syntax normally used. DO
+NOT include your prefix. For example, to load the example above, which
+extends the Email class, you will use:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;email&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Once loaded you will use the class variable as you normally would for
+the class you are extending. In the case of the email class all calls
+will use:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">some_method</span><span class="p">();</span>
+</pre></div>
+</div>
+</div>
+<div class="section" id="setting-your-own-prefix">
+<h3>Setting Your Own Prefix<a class="headerlink" href="#setting-your-own-prefix" title="Permalink to this headline">¶</a></h3>
+<p>To set your own sub-class prefix, open your
+<em>application/config/config.php</em> file and look for this item:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;subclass_prefix&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;MY_&#39;</span><span class="p">;</span>
+</pre></div>

+<p>CodeIgniter was originally developed by <a class="reference external" href="https://ellislab.com/">Rick Ellis</a>
+(CEO of <a class="reference external" href="https://ellislab.com/">EllisLab, Inc.</a>). The framework was written for
+performance in the real world, with many of the class libraries, helpers, and
+sub-systems borrowed from the code-base of <a class="reference external" href="https://ellislab.com/expressionengine">ExpressionEngine</a>.</p>
+<p>It was, for years, developed and maintained by EllisLab, the ExpressionEngine
+Development Team and a group of community members called the Reactor Team.</p>
+<p>In 2014, CodeIgniter was acquired by the <a class="reference external" href="http://www.bcit.ca/">British Columbia Institute of Technology</a> and was then officially announced as a community-maintained
+project.</p>
+<p>Bleeding edge development is spearheaded by the handpicked contributors
+of the Reactor Team.</p>
+<p>A hat tip goes to Ruby on Rails for inspiring us to create a PHP framework, and
+for bringing frameworks into the general consciousness of the web community.</p>

+<h1>Using CodeIgniter Drivers<a class="headerlink" href="#using-codeigniter-drivers" title="Permalink to this headline">¶</a></h1>
+<p>Drivers are a special type of Library that has a parent class and any
+number of potential child classes. Child classes have access to the
+parent class, but not their siblings. Drivers provide an elegant syntax
+in your <a class="reference internal" href="controllers.html"><em>controllers</em></a> for libraries that benefit
+from or require being broken down into discrete classes.</p>
+<p>Drivers are found in the <em>system/libraries/</em> directory, in their own
+sub-directory which is identically named to the parent library class.
+Also inside that directory is a subdirectory named drivers, which
+contains all of the possible child class files.</p>
+<p>To use a driver you will initialize it within a controller using the
+following initialization method:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">driver</span><span class="p">(</span><span class="s1">&#39;class_name&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Where class name is the name of the driver class you want to invoke. For
+example, to load a driver named &#8220;Some_parent&#8221; you would do this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">driver</span><span class="p">(</span><span class="s1">&#39;some_parent&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Methods of that class can then be invoked with:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">some_parent</span><span class="o">-&gt;</span><span class="na">some_method</span><span class="p">();</span>
+</pre></div>
+</div>
+<p>The child classes, the drivers themselves, can then be called directly
+through the parent class, without initializing them:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">some_parent</span><span class="o">-&gt;</span><span class="na">child_one</span><span class="o">-&gt;</span><span class="na">some_method</span><span class="p">();</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">some_parent</span><span class="o">-&gt;</span><span class="na">child_two</span><span class="o">-&gt;</span><span class="na">another_method</span><span class="p">();</span>

+<h1>Handling Multiple Environments<a class="headerlink" href="#handling-multiple-environments" title="Permalink to this headline">¶</a></h1>
+<p>Developers often desire different system behavior depending on whether
+an application is running in a development or production environment.
+For example, verbose error output is something that would be useful
+while developing an application, but it may also pose a security issue
+when &#8220;live&#8221;.</p>
+<div class="section" id="the-environment-constant">
+<h2>The ENVIRONMENT Constant<a class="headerlink" href="#the-environment-constant" title="Permalink to this headline">¶</a></h2>
+<p>By default, CodeIgniter comes with the environment constant set to use
+the value provided in <tt class="docutils literal"><span class="pre">$_SERVER['CI_ENV']</span></tt>, otherwise defaults to
+&#8216;development&#8217;. At the top of index.php, you will see:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nb">define</span><span class="p">(</span><span class="s1">&#39;ENVIRONMENT&#39;</span><span class="p">,</span> <span class="nb">isset</span><span class="p">(</span><span class="nv">$_SERVER</span><span class="p">[</span><span class="s1">&#39;CI_ENV&#39;</span><span class="p">])</span> <span class="o">?</span> <span class="nv">$_SERVER</span><span class="p">[</span><span class="s1">&#39;CI_ENV&#39;</span><span class="p">]</span> <span class="o">:</span> <span class="s1">&#39;development&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>This server variable can be set in your .htaccess file, or Apache
+config using <a class="reference external" href="https://httpd.apache.org/docs/2.2/mod/mod_env.html#setenv">SetEnv</a>.
+Alternative methods are available for nginx and other servers, or you can
+remove this logic entirely and set the constant based on the server&#8217;s IP address.</p>
+<p>In addition to affecting some basic framework behavior (see the next
+section), you may use this constant in your own development to
+differentiate between which environment you are running in.</p>
+</div>
+<div class="section" id="effects-on-default-framework-behavior">
+<h2>Effects On Default Framework Behavior<a class="headerlink" href="#effects-on-default-framework-behavior" title="Permalink to this headline">¶</a></h2>
+<p>There are some places in the CodeIgniter system where the ENVIRONMENT
+constant is used. This section describes how default framework behavior
+is affected.</p>
+<div class="section" id="error-reporting">
+<h3>Error Reporting<a class="headerlink" href="#error-reporting" title="Permalink to this headline">¶</a></h3>
+<p>Setting the ENVIRONMENT constant to a value of &#8216;development&#8217; will cause
+all PHP errors to be rendered to the browser when they occur.
+Conversely, setting the constant to &#8216;production&#8217; will disable all error
+output. Disabling error reporting in production is a <a class="reference internal" href="security.html"><em>good security
+practice</em></a>.</p>
+</div>
+<div class="section" id="configuration-files">
+<h3>Configuration Files<a class="headerlink" href="#configuration-files" title="Permalink to this headline">¶</a></h3>
+<p>Optionally, you can have CodeIgniter load environment-specific
+configuration files. This may be useful for managing things like
+differing API keys across multiple environments. This is described in
+more detail in the environment section of the <a class="reference internal" href="../libraries/config.html"><em>Config Class</em></a> documentation.</p>

+<h1>Error Handling<a class="headerlink" href="#error-handling" title="Permalink to this headline">¶</a></h1>
+<p>CodeIgniter lets you build error reporting into your applications using
+the functions described below. In addition, it has an error logging
+class that permits error and debugging messages to be saved as text
+files.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">By default, CodeIgniter displays all PHP errors. You might
+wish to change this behavior once your development is complete. You&#8217;ll
+find the error_reporting() function located at the top of your main
+index.php file. Disabling error reporting will NOT prevent log files
+from being written if there are errors.</p>
+</div>
+<p>Unlike most systems in CodeIgniter, the error functions are simple
+procedural interfaces that are available globally throughout the
+application. This approach permits error messages to get triggered
+without having to worry about class/function scoping.</p>
+<p>CodeIgniter also returns a status code whenever a portion of the core
+calls <tt class="docutils literal"><span class="pre">exit()</span></tt>. This exit status code is separate from the HTTP status
+code, and serves as a notice to other processes that may be watching of
+whether the script completed successfully, or if not, what kind of
+problem it encountered that caused it to abort. These values are
+defined in <em>application/config/constants.php</em>. While exit status codes
+are most useful in CLI settings, returning the proper code helps server
+software keep track of your scripts and the health of your application.</p>
+<p>The following functions let you generate errors:</p>
+<dl class="function">
+<dt id="show_error">
+<tt class="descname">show_error</tt><big>(</big><em>$message</em>, <em>$status_code</em>, <em>$heading = 'An Error Was Encountered'</em><big>)</big><a class="headerlink" href="#show_error" title="Permalink to this definition">¶</a></dt>

+<tr class="field-even field"><th class="field-name">Return type:</th><td class="field-body"><p class="first last">void</p>
+</td>

+</table>
+<p>This function will display the error message supplied to it using
+the error template appropriate to your execution:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">application</span><span class="o">/</span><span class="nx">views</span><span class="o">/</span><span class="nx">errors</span><span class="o">/</span><span class="nx">html</span><span class="o">/</span><span class="nx">error_general</span><span class="o">.</span><span class="nx">php</span>
+</pre></div>
+</div>
+<p>or:</p>
+<blockquote>
+<div>application/views/errors/cli/error_general.php</div></blockquote>
+<p>The optional parameter <tt class="docutils literal"><span class="pre">$status_code</span></tt> determines what HTTP status
+code should be sent with the error. If <tt class="docutils literal"><span class="pre">$status_code</span></tt> is less
+than 100, the HTTP status code will be set to 500, and the exit
+status code will be set to <tt class="docutils literal"><span class="pre">$status_code</span> <span class="pre">+</span> <span class="pre">EXIT__AUTO_MIN</span></tt>.
+If that value is larger than <tt class="docutils literal"><span class="pre">EXIT__AUTO_MAX</span></tt>, or if
+<tt class="docutils literal"><span class="pre">$status_code</span></tt> is 100 or higher, the exit status code will be set

+Note that CodeIgniter automatically shows 404 messages if

+<p>This function lets you write messages to your log files. You must
+supply one of three &#8220;levels&#8221; in the first parameter, indicating what
+type of message it is (debug, error, info), with the message itself
+in the second parameter.</p>
+<p>Example:</p>

+</pre></div>
+</div>
+<p>There are three message types:</p>
+<ol class="arabic simple">
+<li>Error Messages. These are actual errors, such as PHP errors or
+user errors.</li>
+<li>Debug Messages. These are messages that assist in debugging. For
+example, if a class has been initialized, you could log this as
+debugging info.</li>
+<li>Informational Messages. These are the lowest priority messages,
+simply giving information regarding some process.</li>
+</ol>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">In order for the log file to actually be written, the
+<em>logs/</em> directory must be writable. In addition, you must
+set the &#8220;threshold&#8221; for logging in
+<em>application/config/config.php</em>. You might, for example,
+only want error messages to be logged, and not the other
+two types. If you set it to zero logging will be disabled.</p>

+<h1>Helper Functions<a class="headerlink" href="#helper-functions" title="Permalink to this headline">¶</a></h1>
+<p>Helpers, as the name suggests, help you with tasks. Each helper file is
+simply a collection of functions in a particular category. There are <strong>URL
+Helpers</strong>, that assist in creating links, there are Form Helpers that help
+you create form elements, <strong>Text Helpers</strong> perform various text formatting
+routines, <strong>Cookie Helpers</strong> set and read cookies, File Helpers help you
+deal with files, etc.</p>
+<p>Unlike most other systems in CodeIgniter, Helpers are not written in an
+Object Oriented format. They are simple, procedural functions. Each
+helper function performs one specific task, with no dependence on other
+functions.</p>
+<p>CodeIgniter does not load Helper Files by default, so the first step in
+using a Helper is to load it. Once loaded, it becomes globally available
+in your <a class="reference internal" href="controllers.html"><em>controller</em></a> and
+<a class="reference internal" href="views.html"><em>views</em></a>.</p>
+<p>Helpers are typically stored in your <strong>system/helpers</strong>, or
+<strong>application/helpers directory</strong>. CodeIgniter will look first in your
+<strong>application/helpers directory</strong>. If the directory does not exist or the
+specified helper is not located there CI will instead look in your
+global <em>system/helpers/</em> directory.</p>
+<div class="section" id="loading-a-helper">
+<h2>Loading a Helper<a class="headerlink" href="#loading-a-helper" title="Permalink to this headline">¶</a></h2>
+<p>Loading a helper file is quite simple using the following method:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">helper</span><span class="p">(</span><span class="s1">&#39;name&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Where <strong>name</strong> is the file name of the helper, without the .php file
+extension or the &#8220;helper&#8221; part.</p>
+<p>For example, to load the <strong>URL Helper</strong> file, which is named
+<strong>url_helper.php</strong>, you would do this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">helper</span><span class="p">(</span><span class="s1">&#39;url&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>A helper can be loaded anywhere within your controller methods (or
+even within your View files, although that&#8217;s not a good practice), as
+long as you load it before you use it. You can load your helpers in your
+controller constructor so that they become available automatically in
+any function, or you can load a helper in a specific function that needs
+it.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">The Helper loading method above does not return a value, so
+don&#8217;t try to assign it to a variable. Just use it as shown.</p>
+</div>
+</div>
+<div class="section" id="loading-multiple-helpers">
+<h2>Loading Multiple Helpers<a class="headerlink" href="#loading-multiple-helpers" title="Permalink to this headline">¶</a></h2>
+<p>If you need to load more than one helper you can specify them in an
+array, like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">helper</span><span class="p">(</span>
+        <span class="k">array</span><span class="p">(</span><span class="s1">&#39;helper1&#39;</span><span class="p">,</span> <span class="s1">&#39;helper2&#39;</span><span class="p">,</span> <span class="s1">&#39;helper3&#39;</span><span class="p">)</span>
+<span class="p">);</span>
+</pre></div>
+</div>
+</div>
+<div class="section" id="auto-loading-helpers">
+<h2>Auto-loading Helpers<a class="headerlink" href="#auto-loading-helpers" title="Permalink to this headline">¶</a></h2>
+<p>If you find that you need a particular helper globally throughout your
+application, you can tell CodeIgniter to auto-load it during system
+initialization. This is done by opening the <strong>application/config/autoload.php</strong>
+file and adding the helper to the autoload array.</p>
+</div>
+<div class="section" id="using-a-helper">
+<h2>Using a Helper<a class="headerlink" href="#using-a-helper" title="Permalink to this headline">¶</a></h2>
+<p>Once you&#8217;ve loaded the Helper File containing the function you intend to
+use, you&#8217;ll call it the way you would a standard PHP function.</p>
+<p>For example, to create a link using the <tt class="docutils literal"><span class="pre">anchor()</span></tt> function in one of
+your view files you would do this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span> <span class="k">echo</span> <span class="nx">anchor</span><span class="p">(</span><span class="s1">&#39;blog/comments&#39;</span><span class="p">,</span> <span class="s1">&#39;Click Here&#39;</span><span class="p">);</span><span class="cp">?&gt;</span>
+</pre></div>
+</div>
+<p>Where &#8220;Click Here&#8221; is the name of the link, and &#8220;blog/comments&#8221; is the
+URI to the controller/method you wish to link to.</p>
+</div>
+<div class="section" id="extending-helpers">
+<h2>&#8220;Extending&#8221; Helpers<a class="headerlink" href="#extending-helpers" title="Permalink to this headline">¶</a></h2>
+<p>To &#8220;extend&#8221; Helpers, create a file in your <strong>application/helpers/</strong> folder
+with an identical name to the existing Helper, but prefixed with <strong>MY_</strong>
+(this item is configurable. See below.).</p>
+<p>If all you need to do is add some functionality to an existing helper -
+perhaps add a function or two, or change how a particular helper
+function operates - then it&#8217;s overkill to replace the entire helper with
+your version. In this case it&#8217;s better to simply &#8220;extend&#8221; the Helper.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">The term &#8220;extend&#8221; is used loosely since Helper functions are
+procedural and discrete and cannot be extended in the traditional
+programmatic sense. Under the hood, this gives you the ability to
+add to or or to replace the functions a Helper provides.</p>
+</div>
+<p>For example, to extend the native <strong>Array Helper</strong> you&#8217;ll create a file
+named <strong>application/helpers/MY_array_helper.php</strong>, and add or override
+functions:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="c1">// any_in_array() is not in the Array Helper, so it defines a new function</span>
+<span class="k">function</span> <span class="nf">any_in_array</span><span class="p">(</span><span class="nv">$needle</span><span class="p">,</span> <span class="nv">$haystack</span><span class="p">)</span>
+<span class="p">{</span>
+        <span class="nv">$needle</span> <span class="o">=</span> <span class="nb">is_array</span><span class="p">(</span><span class="nv">$needle</span><span class="p">)</span> <span class="o">?</span> <span class="nv">$needle</span> <span class="o">:</span> <span class="k">array</span><span class="p">(</span><span class="nv">$needle</span><span class="p">);</span>
+
+        <span class="k">foreach</span> <span class="p">(</span><span class="nv">$needle</span> <span class="k">as</span> <span class="nv">$item</span><span class="p">)</span>
+        <span class="p">{</span>
+                <span class="k">if</span> <span class="p">(</span><span class="nb">in_array</span><span class="p">(</span><span class="nv">$item</span><span class="p">,</span> <span class="nv">$haystack</span><span class="p">))</span>

+
+        <span class="k">return</span> <span class="k">FALSE</span><span class="p">;</span>

+<h1>Hooks - Extending the Framework Core<a class="headerlink" href="#hooks-extending-the-framework-core" title="Permalink to this headline">¶</a></h1>
+<p>CodeIgniter&#8217;s Hooks feature provides a means to tap into and modify the
+inner workings of the framework without hacking the core files. When
+CodeIgniter runs it follows a specific execution process, diagramed in
+the <a class="reference internal" href="../overview/appflow.html"><em>Application Flow</em></a> page. There may be
+instances, however, where you&#8217;d like to cause some action to take place
+at a particular stage in the execution process. For example, you might
+want to run a script right before your controllers get loaded, or right
+after, or you might want to trigger one of your own scripts in some
+other location.</p>
+<div class="section" id="enabling-hooks">
+<h2>Enabling Hooks<a class="headerlink" href="#enabling-hooks" title="Permalink to this headline">¶</a></h2>
+<p>The hooks feature can be globally enabled/disabled by setting the
+following item in the <strong>application/config/config.php</strong> file:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;enable_hooks&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="k">TRUE</span><span class="p">;</span>
+</pre></div>
+</div>
+</div>
+<div class="section" id="defining-a-hook">
+<h2>Defining a Hook<a class="headerlink" href="#defining-a-hook" title="Permalink to this headline">¶</a></h2>
+<p>Hooks are defined in the <strong>application/config/hooks.php</strong> file.
+Each hook is specified as an array with this prototype:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$hook</span><span class="p">[</span><span class="s1">&#39;pre_controller&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
+        <span class="s1">&#39;class&#39;</span>    <span class="o">=&gt;</span> <span class="s1">&#39;MyClass&#39;</span><span class="p">,</span>
+        <span class="s1">&#39;function&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;Myfunction&#39;</span><span class="p">,</span>
+        <span class="s1">&#39;filename&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;Myclass.php&#39;</span><span class="p">,</span>
+        <span class="s1">&#39;filepath&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;hooks&#39;</span><span class="p">,</span>
+        <span class="s1">&#39;params&#39;</span>   <span class="o">=&gt;</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;beer&#39;</span><span class="p">,</span> <span class="s1">&#39;wine&#39;</span><span class="p">,</span> <span class="s1">&#39;snacks&#39;</span><span class="p">)</span>
+<span class="p">);</span>
+</pre></div>
+</div>
+<p><strong>Notes:</strong></p>
+<p>The array index correlates to the name of the particular hook point you
+want to use. In the above example the hook point is pre_controller. A
+list of hook points is found below. The following items should be
+defined in your associative hook array:</p>
+<ul class="simple">
+<li><strong>class</strong> The name of the class you wish to invoke. If you prefer to
+use a procedural function instead of a class, leave this item blank.</li>
+<li><strong>function</strong> The function (or method) name you wish to call.</li>
+<li><strong>filename</strong> The file name containing your class/function.</li>
+<li><strong>filepath</strong> The name of the directory containing your script.
+Note:
+Your script must be located in a directory INSIDE your <em>application/</em>
+directory, so the file path is relative to that directory. For example,
+if your script is located in <em>application/hooks/</em>, you will simply use
+&#8216;hooks&#8217; as your filepath. If your script is located in
+<em>application/hooks/utilities/</em> you will use &#8216;hooks/utilities&#8217; as your
+filepath. No trailing slash.</li>
+<li><strong>params</strong> Any parameters you wish to pass to your script. This item
+is optional.</li>
+</ul>
+<p>You can also use lambda/anoymous functions (or closures) as hooks, with
+a simpler syntax:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$hook</span><span class="p">[</span><span class="s1">&#39;post_controller&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="k">function</span><span class="p">()</span>
+<span class="p">{</span>
+        <span class="cm">/* do something here */</span>
+<span class="p">};</span>
+</pre></div>
+</div>

+<h2>Multiple Calls to the Same Hook<a class="headerlink" href="#multiple-calls-to-the-same-hook" title="Permalink to this headline">¶</a></h2>
+<p>If want to use the same hook point with more than one script, simply
+make your array declaration multi-dimensional, like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$hook</span><span class="p">[</span><span class="s1">&#39;pre_controller&#39;</span><span class="p">][]</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>

+<p>This permits you to have the same hook point with multiple scripts. The

+</div>
+<div class="section" id="hook-points">
+<h2>Hook Points<a class="headerlink" href="#hook-points" title="Permalink to this headline">¶</a></h2>
+<p>The following is a list of available hook points.</p>
+<ul class="simple">
+<li><strong>pre_system</strong>
+Called very early during system execution. Only the benchmark and
+hooks class have been loaded at this point. No routing or other
+processes have happened.</li>
+<li><strong>pre_controller</strong>
+Called immediately prior to any of your controllers being called.
+All base classes, routing, and security checks have been done.</li>
+<li><strong>post_controller_constructor</strong>
+Called immediately after your controller is instantiated, but prior
+to any method calls happening.</li>
+<li><strong>post_controller</strong>
+Called immediately after your controller is fully executed.</li>
+<li><strong>display_override</strong>
+Overrides the <tt class="docutils literal"><span class="pre">_display()</span></tt> method, used to send the finalized page
+to the web browser at the end of system execution. This permits you
+to use your own display methodology. Note that you will need to
+reference the CI superobject with <tt class="docutils literal"><span class="pre">$this-&gt;CI</span> <span class="pre">=&amp;</span> <span class="pre">get_instance()</span></tt> and
+then the finalized data will be available by calling
+<tt class="docutils literal"><span class="pre">$this-&gt;CI-&gt;output-&gt;get_output()</span></tt>.</li>
+<li><strong>cache_override</strong>
+Enables you to call your own method instead of the <tt class="docutils literal"><span class="pre">_display_cache()</span></tt>
+method in the <a class="reference internal" href="../libraries/output.html"><em>Output Library</em></a>. This permits
+you to use your own cache display mechanism.</li>
+<li><strong>post_system</strong>
+Called after the final rendered page is sent to the browser, at the
+end of system execution after the finalized data is sent to the
+browser.</li>

+<p>All of the available libraries are located in your <em>system/libraries/</em>
+directory. In most cases, to use one of these classes involves initializing
+it within a <a class="reference internal" href="controllers.html"><em>controller</em></a> using the following
+initialization method:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;class_name&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Where &#8216;class_name&#8217; is the name of the class you want to invoke. For
+example, to load the <a class="reference internal" href="../libraries/form_validation.html"><em>Form Validation Library</em></a> you would do this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;form_validation&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Once initialized you can use it as indicated in the user guide page
+corresponding to that class.</p>
+<p>Additionally, multiple libraries can be loaded at the same time by
+passing an array of libraries to the load method.</p>
+<p>Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="k">array</span><span class="p">(</span><span class="s1">&#39;email&#39;</span><span class="p">,</span> <span class="s1">&#39;table&#39;</span><span class="p">));</span>

+<p>By default it is assumed that you only intend to use CodeIgniter to
+manage one application, which you will build in your <em>application/</em>
+directory. It is possible, however, to have multiple sets of
+applications that share a single CodeIgniter installation, or even to
+rename or relocate your application directory.</p>

+<h2>Renaming the Application Directory<a class="headerlink" href="#renaming-the-application-directory" title="Permalink to this headline">¶</a></h2>
+<p>If you would like to rename your application directory you may do so
+as long as you open your main index.php file and set its name using
+the <tt class="docutils literal"><span class="pre">$application_folder</span></tt> variable:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$application_folder</span> <span class="o">=</span> <span class="s1">&#39;application&#39;</span><span class="p">;</span>

+<p>It is possible to move your application directory to a different

+your main index.php and set a <em>full server path</em> in the
+<tt class="docutils literal"><span class="pre">$application_folder</span></tt> variable:</p>

+<p>If you would like to share a common CodeIgniter installation to manage
+several different applications simply put all of the directories located

+<p>For example, let&#8217;s say you want to create two applications, named &#8220;foo&#8221;

+<p>Models are PHP classes that are designed to work with information in

+blog. You might have a model class that contains functions to insert,
+update, and retrieve your blog data. Here is an example of what such a
+model class might look like:</p>

+<p>Model classes are stored in your <strong>application/models/</strong> directory.
+They can be nested within sub-directories if you want this type of
+organization.</p>
+<p>The basic prototype for a model class is this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">Model_name</span> <span class="k">extends</span> <span class="nx">CI_Model</span> <span class="p">{</span>

+        <span class="p">}</span>
+
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>Where <strong>Model_name</strong> is the name of your class. Class names <strong>must</strong> have
+the first letter capitalized with the rest of the name lowercase. Make
+sure your class extends the base Model class.</p>
+<p>The file name must match the class name. For example, if this is your class:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">User_model</span> <span class="k">extends</span> <span class="nx">CI_Model</span> <span class="p">{</span>

+<h2><a class="toc-backref" href="#id4">Loading a Model</a><a class="headerlink" href="#loading-a-model" title="Permalink to this headline">¶</a></h2>
+<p>Your models will typically be loaded and called from within your
+<a class="reference internal" href="controllers.html"><em>controller</em></a> methods. To load a model you will use
+the following method:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">model</span><span class="p">(</span><span class="s1">&#39;model_name&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>If your model is located in a sub-directory, include the relative path
+from your models directory. For example, if you have a model located at
+<em>application/models/blog/Queries.php</em> you&#8217;ll load it using:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">model</span><span class="p">(</span><span class="s1">&#39;blog/queries&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Once loaded, you will access your model methods using an object with the
+same name as your class:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">model</span><span class="p">(</span><span class="s1">&#39;model_name&#39;</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>If you would like your model assigned to a different object name you can
+specify it via the second parameter of the loading method:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">model</span><span class="p">(</span><span class="s1">&#39;model_name&#39;</span><span class="p">,</span> <span class="s1">&#39;foobar&#39;</span><span class="p">);</span>

+<p>Here is an example of a controller, that loads a model, then serves a
+view:</p>

+<h2>Enabling and Disabling Profiler Sections<a class="headerlink" href="#enabling-and-disabling-profiler-sections" title="Permalink to this headline">¶</a></h2>
+<p>Each section of Profiler data can be enabled or disabled by setting a
+corresponding config variable to TRUE or FALSE. This can be done one of
+two ways. First, you can set application wide defaults with the
+<em>application/config/profiler.php</em> config file.</p>
+<p>Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;config&#39;</span><span class="p">]</span>          <span class="o">=</span> <span class="k">FALSE</span><span class="p">;</span>
+<span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;queries&#39;</span><span class="p">]</span>         <span class="o">=</span> <span class="k">FALSE</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>In your controllers, you can override the defaults and config file
+values by calling the <tt class="docutils literal"><span class="pre">set_profiler_sections()</span></tt> method of the
+<a class="reference internal" href="../libraries/output.html"><em>Output Library</em></a>:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$sections</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
+        <span class="s1">&#39;config&#39;</span>  <span class="o">=&gt;</span> <span class="k">TRUE</span><span class="p">,</span>

+<p><a class="reference external" href="http://php.net/">PHP</a> version 5.6 or newer is recommended.</p>
+<p>It should work on 5.3.7 as well, but we strongly advise you NOT to run
+such old versions of PHP, because of potential security and performance
+issues, as well as missing features.</p>
+<p>A database is required for most web application programming.
+Currently supported databases are:</p>
+<blockquote>

+<li>MySQL (5.1+) via the <em>mysql</em> (deprecated), <em>mysqli</em> and <em>pdo</em> drivers</li>
+<li>Oracle via the <em>oci8</em> and <em>pdo</em> drivers</li>
+<li>PostgreSQL via the <em>postgre</em> and <em>pdo</em> drivers</li>
+<li>MS SQL via the <em>mssql</em>, <em>sqlsrv</em> (version 2005 and above only) and <em>pdo</em> drivers</li>
+<li>SQLite via the <em>sqlite</em> (version 2), <em>sqlite3</em> (version 3) and <em>pdo</em> drivers</li>
+<li>CUBRID via the <em>cubrid</em> and <em>pdo</em> drivers</li>
+<li>Interbase/Firebird via the <em>ibase</em> and <em>pdo</em> drivers</li>

+<p>In order to help out, CodeIgniter uses a series of function, method,

+override them. The following is a list of reserved names. Do not name

+<h1>URI Routing<a class="headerlink" href="#uri-routing" title="Permalink to this headline">¶</a></h1>
+<p>Typically there is a one-to-one relationship between a URL string and
+its corresponding controller class/method. The segments in a URI
+normally follow this pattern:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">class</span><span class="o">/</span><span class="nx">function</span><span class="o">/</span><span class="nx">id</span><span class="o">/</span>
+</pre></div>
+</div>
+<p>In some instances, however, you may want to remap this relationship so
+that a different class/method can be called instead of the one
+corresponding to the URL.</p>
+<p>For example, let&#8217;s say you want your URLs to have this prototype:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">product</span><span class="o">/</span><span class="mi">1</span><span class="o">/</span>
+<span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">product</span><span class="o">/</span><span class="mi">2</span><span class="o">/</span>
+<span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">product</span><span class="o">/</span><span class="mi">3</span><span class="o">/</span>
+<span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">product</span><span class="o">/</span><span class="mi">4</span><span class="o">/</span>
+</pre></div>
+</div>
+<p>Normally the second segment of the URL is reserved for the method
+name, but in the example above it instead has a product ID. To
+overcome this, CodeIgniter allows you to remap the URI handler.</p>
+<div class="section" id="setting-your-own-routing-rules">
+<h2>Setting your own routing rules<a class="headerlink" href="#setting-your-own-routing-rules" title="Permalink to this headline">¶</a></h2>
+<p>Routing rules are defined in your <em>application/config/routes.php</em> file.
+In it you&#8217;ll see an array called <tt class="docutils literal"><span class="pre">$route</span></tt> that permits you to specify
+your own routing criteria. Routes can either be specified using wildcards
+or Regular Expressions.</p>
+</div>
+<div class="section" id="wildcards">
+<h2>Wildcards<a class="headerlink" href="#wildcards" title="Permalink to this headline">¶</a></h2>
+<p>A typical wildcard route might look something like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$route</span><span class="p">[</span><span class="s1">&#39;product/:num&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;catalog/product_lookup&#39;</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>In a route, the array key contains the URI to be matched, while the
+array value contains the destination it should be re-routed to. In the

+&#8220;catalog&#8221; class and the &#8220;product_lookup&#8221; method are instead used.</p>
+<p>You can match literal values or you can use two wildcard types:</p>
+<p><strong>(:num)</strong> will match a segment containing only numbers.
+<strong>(:any)</strong> will match a segment containing any character (except for &#8216;/&#8217;, which is the segment delimiter).</p>

+<h2>Regular Expressions<a class="headerlink" href="#regular-expressions" title="Permalink to this headline">¶</a></h2>
+<p>If you prefer you can use regular expressions to define your routing

+<p>With regular expressions, you can also catch multiple segments at once.

+<h2>Using HTTP verbs in routes<a class="headerlink" href="#using-http-verbs-in-routes" title="Permalink to this headline">¶</a></h2>
+<p>It is possible to use HTTP verbs (request method) to define your routing rules.
+This is particularly useful when building RESTful applications. You can use standard HTTP
+verbs (GET, PUT, POST, DELETE, PATCH) or a custom one such (e.g. PURGE). HTTP verb rules
+are case-insensitive. All you need to do is to add the verb as an array key to your route.
+Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$route</span><span class="p">[</span><span class="s1">&#39;products&#39;</span><span class="p">][</span><span class="s1">&#39;put&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;product/insert&#39;</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>In the above example, a PUT request to URI &#8220;products&#8221; would call the <tt class="docutils literal"><span class="pre">Product::insert()</span></tt>
+controller method.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$route</span><span class="p">[</span><span class="s1">&#39;products/(:num)&#39;</span><span class="p">][</span><span class="s1">&#39;DELETE&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;product/delete/$1&#39;</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>A DELETE request to URL with &#8220;products&#8221; as first the segment and a number in the second will be
+mapped to the <tt class="docutils literal"><span class="pre">Product::delete()</span></tt> method, passing the numeric value as the first parameter.</p>
+<p>Using HTTP verbs is of course, optional.</p>
+</div>
+<div class="section" id="reserved-routes">
+<h2>Reserved Routes<a class="headerlink" href="#reserved-routes" title="Permalink to this headline">¶</a></h2>
+<p>There are three reserved routes:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$route</span><span class="p">[</span><span class="s1">&#39;default_controller&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;welcome&#39;</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>This route points to the action that should be executed if the URI contains
+no data, which will be the case when people load your root URL.
+The setting accepts a <strong>controller/method</strong> value and <tt class="docutils literal"><span class="pre">index()</span></tt> would be
+the default method if you don&#8217;t specify one. In the above example, it is
+<tt class="docutils literal"><span class="pre">Welcome::index()</span></tt> that would be called.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">You can NOT use a directory as a part of this setting!</p>
+</div>
+<p>You are encouraged to always have a default route as otherwise a 404 page
+will appear by default.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$route</span><span class="p">[</span><span class="s1">&#39;404_override&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;&#39;</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>This route indicates which controller class should be loaded if the
+requested controller is not found. It will override the default 404
+error page. Same per-directory rules as with &#8216;default_controller&#8217;
+apply here as well.</p>
+<p>It won&#8217;t affect to the <tt class="docutils literal"><span class="pre">show_404()</span></tt> function, which will
+continue loading the default <em>error_404.php</em> file at
+<em>application/views/errors/error_404.php</em>.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$route</span><span class="p">[</span><span class="s1">&#39;translate_uri_dashes&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="k">FALSE</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>As evident by the boolean value, this is not exactly a route. This
+option enables you to automatically replace dashes (&#8216;-&#8216;) with
+underscores in the controller and method URI segments, thus saving you
+additional route entries if you need to do that.
+This is required, because the dash isn&#8217;t a valid class or method name
+character and would cause a fatal error if you try to use it.</p>

+<h2>URI Security<a class="headerlink" href="#uri-security" title="Permalink to this headline">¶</a></h2>
+<p>CodeIgniter is fairly restrictive regarding which characters it allows
+in your URI strings in order to help minimize the possibility that
+malicious data can be passed to your application. URIs may only contain
+the following:</p>
+<ul class="simple">
+<li>Alpha-numeric text (latin characters only)</li>
+<li>Tilde: ~</li>
+<li>Percent sign: %</li>
+<li>Period: .</li>

+<div class="section" id="display-errors">
+<h2>display_errors<a class="headerlink" href="#display-errors" title="Permalink to this headline">¶</a></h2>
+<p>In production environments, it is typically desirable to &#8220;disable&#8221; PHP&#8217;s
+error reporting by setting the internal <em>display_errors</em> flag to a value
+of 0. This disables native PHP errors from being rendered as output,
+which may potentially contain sensitive information.</p>
+<p>Setting CodeIgniter&#8217;s <strong>ENVIRONMENT</strong> constant in index.php to a value of
+<strong>&#8216;production&#8217;</strong> will turn off these errors. In development mode, it is
+recommended that a value of &#8216;development&#8217; is used. More information
+about differentiating between environments can be found on the
+<a class="reference internal" href="environments.html"><em>Handling Environments</em></a> page.</p>

+<div class="section" id="best-practices">
+<h3>Best Practices<a class="headerlink" href="#best-practices" title="Permalink to this headline">¶</a></h3>
+<p>Before accepting any data into your application, whether it be POST data
+from a form submission, COOKIE data, URI data, XML-RPC data, or even
+data from the SERVER array, you are encouraged to practice this three
+step approach:</p>
+<ol class="arabic simple">
+<li>Validate the data to ensure it conforms to the correct type, length,
+size, etc.</li>
+<li>Filter the data as if it were tainted.</li>
+<li>Escape the data before submitting it into your database or outputting
+it to a browser.</li>
+</ol>
+<p>CodeIgniter provides the following functions and tips to assist you
+in this process:</p>
+</div>
+</div>
+<div class="section" id="xss-filtering">
+<h2>XSS Filtering<a class="headerlink" href="#xss-filtering" title="Permalink to this headline">¶</a></h2>
+<p>CodeIgniter comes with a Cross Site Scripting filter. This filter
+looks for commonly used techniques to embed malicious JavaScript into
+your data, or other types of code that attempt to hijack cookies or
+do other malicious things. The XSS Filter is described
+<a class="reference internal" href="../libraries/security.html"><em>here</em></a>.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">XSS filtering should <em>only be performed on output</em>. Filtering
+input data may modify the data in undesirable ways, including
+stripping special characters from passwords, which reduces
+security instead of improving it.</p>
+</div>
+</div>
+<div class="section" id="csrf-protection">
+<h2>CSRF protection<a class="headerlink" href="#csrf-protection" title="Permalink to this headline">¶</a></h2>
+<p>CSRF stands for Cross-Site Request Forgery, which is the process of an
+attacker tricking their victim into unknowingly submitting a request.</p>
+<p>CodeIgniter provides CSRF protection out of the box, which will get
+automatically triggered for every non-GET HTTP request, but also needs
+you to create your submit forms in a certain way. This is explained in
+the <a class="reference internal" href="../libraries/security.html"><em>Security Library</em></a> documentation.</p>
+</div>
+<div class="section" id="password-handling">
+<h2>Password handling<a class="headerlink" href="#password-handling" title="Permalink to this headline">¶</a></h2>
+<p>It is <em>critical</em> that you handle passwords in your application properly.</p>
+<p>Unfortunately, many developers don&#8217;t know how to do that, and the web is
+full of outdated or otherwise wrongful advices, which doesn&#8217;t help.</p>
+<p>We would like to give you a list of combined do&#8217;s and don&#8217;ts to help you
+with that. Please read below.</p>
+<ul>
+<li><p class="first">DO NOT store passwords in plain-text format.</p>
+<p>Always <strong>hash</strong> your passwords.</p>
+</li>
+<li><p class="first">DO NOT use Base64 or similar encoding for storing passwords.</p>
+<p>This is as good as storing them in plain-text. Really. Do <strong>hashing</strong>,
+not <em>encoding</em>.</p>
+<p>Encoding, and encryption too, are two-way processes. Passwords are
+secrets that must only be known to their owner, and thus must work
+only in one direction. Hashing does that - there&#8217;s <em>no</em> un-hashing or
+de-hashing, but there is decoding and decryption.</p>
+</li>
+<li><p class="first">DO NOT use weak or broken hashing algorithms like MD5 or SHA1.</p>
+<p>These algorithms are old, proven to be flawed, and not designed for
+password hashing in the first place.</p>
+<p>Also, DON&#8217;T invent your own algorithms.</p>
+<p>Only use strong password hashing algorithms like BCrypt, which is used
+in PHP&#8217;s own <a class="reference external" href="http://php.net/password">Password Hashing</a> functions.</p>
+<p>Please use them, even if you&#8217;re not running PHP 5.5+, CodeIgniter
+provides them for you.</p>
+</li>
+<li><p class="first">DO NOT ever display or send a password in plain-text format!</p>
+<p>Even to the password&#8217;s owner, if you need a &#8220;Forgotten password&#8221;
+feature, just randomly generate a new, one-time (this is also important)
+password and send that instead.</p>
+</li>
+<li><p class="first">DO NOT put unnecessary limits on your users&#8217; passwords.</p>
+<p>If you&#8217;re using a hashing algorithm other than BCrypt (which has a limit
+of 72 characters), you should set a relatively high limit on password
+lengths in order to mitigate DoS attacks - say, 1024 characters.</p>
+<p>Other than that however, there&#8217;s no point in forcing a rule that a
+password can only be up to a number of characters, or that it can&#8217;t
+contain a certain set of special characters.</p>
+<p>Not only does this <strong>reduce</strong> security instead of improving it, but
+there&#8217;s literally no reason to do it. No technical limitations and
+no (practical) storage constraints apply once you&#8217;ve hashed them, none!</p>
+</li>
+</ul>
+</div>
+<div class="section" id="validate-input-data">
+<h2>Validate input data<a class="headerlink" href="#validate-input-data" title="Permalink to this headline">¶</a></h2>
+<p>CodeIgniter has a <a class="reference internal" href="../libraries/form_validation.html"><em>Form Validation Library</em></a> that assists you in
+validating, filtering, and prepping your data.</p>
+<p>Even if that doesn&#8217;t work for your use case however, be sure to always
+validate and sanitize all input data. For example, if you expect a numeric
+string for an input variable, you can check for that with <tt class="docutils literal"><span class="pre">is_numeric()</span></tt>
+or <tt class="docutils literal"><span class="pre">ctype_digit()</span></tt>. Always try to narrow down your checks to a certain
+pattern.</p>
+<p>Have it in mind that this includes not only <tt class="docutils literal"><span class="pre">$_POST</span></tt> and <tt class="docutils literal"><span class="pre">$_GET</span></tt>
+variables, but also cookies, the user-agent string and basically
+<em>all data that is not created directly by your own code</em>.</p>
+</div>
+<div class="section" id="escape-all-data-before-database-insertion">
+<h2>Escape all data before database insertion<a class="headerlink" href="#escape-all-data-before-database-insertion" title="Permalink to this headline">¶</a></h2>
+<p>Never insert information into your database without escaping it.
+Please see the section that discusses <a class="reference internal" href="../database/queries.html"><em>database queries</em></a> for more information.</p>
+</div>
+<div class="section" id="hide-your-files">
+<h2>Hide your files<a class="headerlink" href="#hide-your-files" title="Permalink to this headline">¶</a></h2>
+<p>Another good security practice is to only leave your <em>index.php</em>
+and &#8220;assets&#8221; (e.g. .js, css and image files) under your server&#8217;s
+<em>webroot</em> directory (most commonly named &#8220;htdocs/&#8221;). These are
+the only files that you would need to be accessible from the web.</p>
+<p>Allowing your visitors to see anything else would potentially
+allow them to access sensitive data, execute scripts, etc.</p>
+<p>If you&#8217;re not allowed to do that, you can try using a .htaccess
+file to restrict access to those resources.</p>
+<p>CodeIgniter will have an index.html file in all of its
+directories in an attempt to hide some of this data, but have
+it in mind that this is not enough to prevent a serious
+attacker.</p>

+compatible with PHP 5.3.7. Your code must either be compatible with this
+requirement, provide a suitable fallback, or be an optional feature that
+dies quietly without affecting a user&#8217;s application.</p>

+<p>Use tabs for whitespace in your code, not spaces. This may seem like a

+<h1>CodeIgniter URLs<a class="headerlink" href="#codeigniter-urls" title="Permalink to this headline">¶</a></h1>
+<p>By default, URLs in CodeIgniter are designed to be search-engine and
+human friendly. Rather than using the standard &#8220;query string&#8221; approach
+to URLs that is synonymous with dynamic systems, CodeIgniter uses a
+<strong>segment-based</strong> approach:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">news</span><span class="o">/</span><span class="nx">article</span><span class="o">/</span><span class="nx">my_article</span>
+</pre></div>
+</div>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">Query string URLs can be optionally enabled, as described
+below.</p>
+</div>
+<div class="section" id="uri-segments">
+<h2>URI Segments<a class="headerlink" href="#uri-segments" title="Permalink to this headline">¶</a></h2>
+<p>The segments in the URL, in following with the Model-View-Controller
+approach, usually represent:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">class</span><span class="o">/</span><span class="nx">function</span><span class="o">/</span><span class="nx">ID</span>
+</pre></div>
+</div>
+<ol class="arabic simple">
+<li>The first segment represents the controller <strong>class</strong> that should be
+invoked.</li>
+<li>The second segment represents the class <strong>function</strong>, or method, that
+should be called.</li>
+<li>The third, and any additional segments, represent the ID and any
+variables that will be passed to the controller.</li>
+</ol>
+<p>The <a class="reference internal" href="../libraries/uri.html"><em>URI Library</em></a> and the <a class="reference internal" href="../helpers/url_helper.html"><em>URL Helper</em></a> contain functions that make it easy to work
+with your URI data. In addition, your URLs can be remapped using the
+<a class="reference internal" href="routing.html"><em>URI Routing</em></a> feature for more flexibility.</p>
+</div>
+<div class="section" id="removing-the-index-php-file">
+<h2>Removing the index.php file<a class="headerlink" href="#removing-the-index-php-file" title="Permalink to this headline">¶</a></h2>
+<p>By default, the <strong>index.php</strong> file will be included in your URLs:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">news</span><span class="o">/</span><span class="nx">article</span><span class="o">/</span><span class="nx">my_article</span>
+</pre></div>
+</div>
+<p>If your Apache server has <em>mod_rewrite</em> enabled, you can easily remove this
+file by using a .htaccess file with some simple rules. Here is an example
+of such a file, using the &#8220;negative&#8221; method in which everything is redirected

+<h2>Adding a URL Suffix<a class="headerlink" href="#adding-a-url-suffix" title="Permalink to this headline">¶</a></h2>
+<p>In your <strong>config/config.php</strong> file you can specify a suffix that will be
+added to all URLs generated by CodeIgniter. For example, if a URL is
+this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">products</span><span class="o">/</span><span class="nx">view</span><span class="o">/</span><span class="nx">shoes</span>
+</pre></div>
+</div>
+<p>You can optionally add a suffix, like <strong>.html,</strong> making the page appear to
+be of a certain type:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">products</span><span class="o">/</span><span class="nx">view</span><span class="o">/</span><span class="nx">shoes</span><span class="o">.</span><span class="nx">html</span>
+</pre></div>
+</div>
+</div>
+<div class="section" id="enabling-query-strings">
+<h2>Enabling Query Strings<a class="headerlink" href="#enabling-query-strings" title="Permalink to this headline">¶</a></h2>
+<p>In some cases you might prefer to use query strings URLs:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">?</span><span class="nx">c</span><span class="o">=</span><span class="nx">products</span><span class="o">&amp;</span><span class="nx">m</span><span class="o">=</span><span class="nx">view</span><span class="o">&amp;</span><span class="nx">id</span><span class="o">=</span><span class="mi">345</span>
+</pre></div>
+</div>
+<p>CodeIgniter optionally supports this capability, which can be enabled in
+your <strong>application/config.php</strong> file. If you open your config file you&#8217;ll
+see these items:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;enable_query_strings&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="k">FALSE</span><span class="p">;</span>

+</pre></div>
+</div>
+<p>If you change &#8220;enable_query_strings&#8221; to TRUE this feature will become
+active. Your controllers and functions will then be accessible using the
+&#8220;trigger&#8221; words you&#8217;ve set to invoke your controllers and methods:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">?</span><span class="nx">c</span><span class="o">=</span><span class="nx">controller</span><span class="o">&amp;</span><span class="nx">m</span><span class="o">=</span><span class="nx">method</span>
+</pre></div>
+</div>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">If you are using query strings you will have to build your own
+URLs, rather than utilizing the URL helpers (and other helpers
+that generate URLs, like some of the form helpers) as these are
+designed to work with segment based URLs.</p>

+<p>A view is simply a web page, or a page fragment, like a header, footer,
+sidebar, etc. In fact, views can flexibly be embedded within other views
+(within other views, etc., etc.) if you need this type of hierarchy.</p>
+<p>Views are never called directly, they must be loaded by a
+<a class="reference internal" href="controllers.html"><em>controller</em></a>. Remember that in an MVC framework, the
+Controller acts as the traffic cop, so it is responsible for fetching a
+particular view. If you have not read the
+<a class="reference internal" href="controllers.html"><em>Controllers</em></a> page you should do so before
+continuing.</p>
+<p>Using the example controller you created in the
+<a class="reference internal" href="controllers.html"><em>controller</em></a> page, let&#8217;s add a view to it.</p>
+<div class="section" id="creating-a-view">
+<h2>Creating a View<a class="headerlink" href="#creating-a-view" title="Permalink to this headline">¶</a></h2>
+<p>Using your text editor, create a file called blogview.php, and put this

+<p>CodeIgniter is an Application Development Framework - a toolkit - for
+people who build web sites using PHP. Its goal is to enable you to
+develop projects much faster than you could if you were writing code
+from scratch, by providing a rich set of libraries for commonly needed
+tasks, as well as a simple interface and logical structure to access
+these libraries. CodeIgniter lets you creatively focus on your project
+by minimizing the amount of code needed for a given task.</p>

+<h2>Who is CodeIgniter For?<a class="headerlink" href="#who-is-codeigniter-for" title="Permalink to this headline">¶</a></h2>
+<p>CodeIgniter is right for you if:</p>
+<ul class="simple">
+<li>You want a framework with a small footprint.</li>
+<li>You need exceptional performance.</li>
+<li>You need broad compatibility with standard hosting accounts that run
+a variety of PHP versions and configurations.</li>
+<li>You want a framework that requires nearly zero configuration.</li>
+<li>You want a framework that does not require you to use the command
+line.</li>
+<li>You want a framework that does not require you to adhere to
+restrictive coding rules.</li>
+<li>You are not interested in large-scale monolithic libraries like PEAR.</li>
+<li>You do not want to be forced to learn a templating language (although
+a template parser is optionally available if you desire one).</li>
+<li>You eschew complexity, favoring simple solutions.</li>
+<li>You need clear, thorough documentation.</li>

+<p>Sub-folders contained within the directory will be mapped as well. If

+parameter (integer). A depth of 1 will only map the top level directory:</p>

+</div>
+<p>By default, hidden files will not be included in the returned array. To

+<p>Generates server headers which force data to be downloaded to your
+desktop. Useful with file downloads. The first parameter is the <strong>name
+you want the downloaded file to be named</strong>, the second parameter is the
+file data.</p>
+<p>If you set the second parameter to NULL and <tt class="docutils literal"><span class="pre">$filename</span></tt> is an existing, readable
+file path, then its content will be read instead.</p>
+<p>If you set the third parameter to boolean TRUE, then the actual file MIME type
+(based on the filename extension) will be sent, so that if your browser has a
+handler for that type - it can use it.</p>
+<p>Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$data</span> <span class="o">=</span> <span class="s1">&#39;Here is some text!&#39;</span><span class="p">;</span>

+</pre></div>
+</div>
+<p>If you want to download an existing file from your server you&#8217;ll need to

+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="c1">// Contents of photo.jpg will be automatically read</span>

+<p>You may need to use HTML and characters such as quotes within your form

+<a class="reference internal" href="../general/common_functions.html"><em>common function</em></a>
+<tt class="xref py py-func docutils literal"><span class="pre">html_escape()</span></tt>.</p>
+<p>Consider the following example:</p>

+<p>Creates an opening form tag with a base URL <strong>built from your config preferences</strong>.
+It will optionally let you add form attributes and hidden input fields, and
+will always add the <cite>accept-charset</cite> attribute based on the charset value in your
+config file.</p>
+<p>The main benefit of using this tag rather than hard coding your own HTML is that
+it permits your site to be more portable in the event your URLs ever change.</p>
+<p>Here&#8217;s a simple example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">form_open</span><span class="p">(</span><span class="s1">&#39;email/send&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The above example would create a form that points to your base URL plus the
+&#8220;email/send&#8221; URI segments, like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">form</span> <span class="nx">method</span><span class="o">=</span><span class="s2">&quot;post&quot;</span> <span class="nx">accept</span><span class="o">-</span><span class="nx">charset</span><span class="o">=</span><span class="s2">&quot;utf-8&quot;</span> <span class="nx">action</span><span class="o">=</span><span class="s2">&quot;http://example.com/index.php/email/send&quot;</span><span class="o">&gt;</span>
+</pre></div>
+</div>
+<p><strong>Adding Attributes</strong></p>
+<blockquote>
+<div><p>Attributes can be added by passing an associative array to the second
+parameter, like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$attributes</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;class&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;email&#39;</span><span class="p">,</span> <span class="s1">&#39;id&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;myform&#39;</span><span class="p">);</span>
+<span class="k">echo</span> <span class="nx">form_open</span><span class="p">(</span><span class="s1">&#39;email/send&#39;</span><span class="p">,</span> <span class="nv">$attributes</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Alternatively, you can specify the second parameter as a string:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">form_open</span><span class="p">(</span><span class="s1">&#39;email/send&#39;</span><span class="p">,</span> <span class="s1">&#39;class=&quot;email&quot; id=&quot;myform&quot;&#39;</span><span class="p">);</span>
+</pre></div>

+<p>Lets you create HTML heading tags. The first parameter will contain the
+data, the second the size of the heading. Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">heading</span><span class="p">(</span><span class="s1">&#39;Welcome!&#39;</span><span class="p">,</span> <span class="mi">3</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The above would produce: &lt;h3&gt;Welcome!&lt;/h3&gt;</p>
+<p>Additionally, in order to add attributes to the heading tag such as HTML
+classes, ids or inline styles, a third parameter accepts either a string
+or an array:</p>

+<em>type</em>, <em>title</em>, <em>media</em> and <em>index_page</em>.</p>
+<p><em>index_page</em> is a boolean value that specifies if the <em>href</em> should have

+<p>Does a &#8220;header redirect&#8221; to the URI specified. If you specify the full
+site URL that link will be built, but for local links simply providing
+the URI segments to the controller you want to direct to will create the
+link. The function will build the URL based on your config file values.</p>
+<p>The optional second parameter allows you to force a particular redirection
+method. The available methods are <strong>auto</strong>, <strong>location</strong> and <strong>refresh</strong>,
+with location being faster but less reliable on IIS servers.
+The default is <strong>auto</strong>, which will attempt to intelligently choose the
+method based on the server environment.</p>
+<p>The optional third parameter allows you to send a specific HTTP Response
+Code - this could be used for example to create 301 redirects for search

+<h1>Installation Instructions<a class="headerlink" href="#installation-instructions" title="Permalink to this headline">¶</a></h1>
+<p>CodeIgniter is installed in four steps:</p>
+<ol class="arabic simple">
+<li>Unzip the package.</li>
+<li>Upload the CodeIgniter folders and files to your server. Normally the
+<em>index.php</em> file will be at your root.</li>
+<li>Open the <em>application/config/config.php</em> file with a text editor and
+set your base URL. If you intend to use encryption or sessions, set
+your encryption key.</li>
+<li>If you intend to use a database, open the
+<em>application/config/database.php</em> file with a text editor and set your
+database settings.</li>
+</ol>
+<p>If you wish to increase security by hiding the location of your
+CodeIgniter files you can rename the system and application folders to
+something more private. If you do rename them, you must open your main
+<em>index.php</em> file and set the <tt class="docutils literal"><span class="pre">$system_path</span></tt> and <tt class="docutils literal"><span class="pre">$application_folder</span></tt>
+variables at the top of the file with the new name you&#8217;ve chosen.</p>
+<p>For the best security, both the system and any application folders
+should be placed above web root so that they are not directly accessible
+via a browser. By default, <em>.htaccess</em> files are included in each folder
+to help prevent direct access, but it is best to remove them from public
+access entirely in case the web server configuration changes or doesn&#8217;t
+abide by the <em>.htaccess</em>.</p>
+<p>If you would like to keep your views public it is also possible to move
+the views folder out of your application folder.</p>
+<p>After moving them, open your main index.php file and set the
+<tt class="docutils literal"><span class="pre">$system_path</span></tt>, <tt class="docutils literal"><span class="pre">$application_folder</span></tt> and <tt class="docutils literal"><span class="pre">$view_folder</span></tt> variables,
+preferably with a full path, e.g. &#8216;<em>/www/MyUser/system</em>&#8216;.</p>
+<p>One additional measure to take in production environments is to disable
+PHP error reporting and any other development-only functionality. In
+CodeIgniter, this can be done by setting the <tt class="docutils literal"><span class="pre">ENVIRONMENT</span></tt> constant, which
+is more fully described on the <a class="reference internal" href="../general/security.html"><em>security
+page</em></a>.</p>
+<p>That&#8217;s it!</p>
+<p>If you&#8217;re new to CodeIgniter, please read the <a class="reference internal" href="../overview/getting_started.html"><em>Getting
+Started</em></a> section of the User Guide
+to begin learning how to build dynamic PHP applications. Enjoy!</p>

+<p>If you find that no matter what you put in your URL only your default
+page is loading, it might be that your server does not support the
+REQUEST_URI variable needed to serve search-engine friendly URLs. As a
+first step, open your <em>application/config/config.php</em> file and look for
+the URI Protocol information. It will recommend that you try a couple
+alternate settings. If it still doesn&#8217;t work after you&#8217;ve tried this
+you&#8217;ll need to force CodeIgniter to add a question mark to your URLs. To
+do this open your <em>application/config/config.php</em> file and change this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;index_page&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s2">&quot;index.php&quot;</span><span class="p">;</span>

+<h2>Step 2: Update your Session Table<a class="headerlink" href="#step-2-update-your-session-table" title="Permalink to this headline">¶</a></h2>
+<p>If you are using the Session class in your application, AND if you are
+storing session data to a database, you must add a new column named
+user_data to your session table. Here is an example of what this column
+might look like for MySQL:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">user_data</span> <span class="nx">text</span> <span class="k">NOT</span> <span class="k">NULL</span>
+</pre></div>
+</div>
+<p>To add this column you will run a query similar to this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">ALTER</span> <span class="nx">TABLE</span> <span class="sb">`ci_sessions`</span> <span class="nx">ADD</span> <span class="sb">`user_data`</span> <span class="nx">text</span> <span class="k">NOT</span> <span class="k">NULL</span>
+</pre></div>

+the <a class="reference internal" href="../libraries/sessions.html"><em>Session class</em></a> page.</p>

+<h2>Step 3: Update your Validation Syntax<a class="headerlink" href="#step-3-update-your-validation-syntax" title="Permalink to this headline">¶</a></h2>
+<p>This is an <strong>optional</strong>, but recommended step, for people currently
+using the Validation class. CI 1.7 introduces a new <a class="reference internal" href="../libraries/form_validation.html"><em>Form Validation
+class</em></a>, which deprecates the old
+Validation library. We have left the old one in place so that existing
+applications that use it will not break, but you are encouraged to
+migrate to the new version as soon as possible. Please read the user
+guide carefully as the new library works a little differently, and has
+several new features.</p>

+not store Encrypted data permanently, or is on an environment that does
+not support Mcrypt, you may skip this step.</p>
+</div>
+<p>The Encrypt library has had a number of improvements, some for
+encryption strength and some for performance, that has an unavoidable
+consequence of making it no longer possible to decode encrypted data
+produced by the original version of this library. To help with the
+transition, a new method has been added, encode_from_legacy() that
+will decode the data with the original algorithm and return a re-encoded
+string using the improved methods. This will enable you to easily
+replace stale encrypted data with fresh in your applications, either on
+the fly or en masse.</p>

+<p>Starting with CodeIgniter 3.0, all class filenames (libraries, drivers, controllers
+and models) must be named in a Ucfirst-like manner or in other words - they must
+start with a capital letter.</p>
+<p>For example, if you have the following library file:</p>
+<blockquote>
+<div>application/libraries/mylibrary.php</div></blockquote>
+<p>... then you&#8217;ll have to rename it to:</p>
+<blockquote>
+<div>application/libraries/Mylibrary.php</div></blockquote>
+<p>The same goes for driver libraries and extensions and/or overrides of CodeIgniter&#8217;s
+own libraries and core classes.</p>
+<blockquote>
+<div>application/libraries/MY_email.php
+application/core/MY_log.php</div></blockquote>
+<p>The above files should respectively be renamed to the following:</p>
+<blockquote>
+<div>application/libraries/MY_Email.php
+application/core/MY_Log.php</div></blockquote>
+<p>Controllers:</p>
+<blockquote>
+<div>application/controllers/welcome.php     -&gt;      application/controllers/Welcome.php</div></blockquote>
+<p>Models:</p>
+<blockquote>
+<div>application/models/misc_model.php       -&gt;      application/models/Misc_model.php</div></blockquote>
+<p>Please note that this DOES NOT affect directories, configuration files, views,
+helpers, hooks and anything else - it is only applied to classes.</p>
+<p>You must now follow just one simple rule - class names in Ucfirst and everything else
+in lowercase.</p>

+<p>The <a class="reference internal" href="../libraries/sessions.html"><em>Session Library</em></a> has been completely
+re-written in CodeIgniter 3 and now comes with a bunch of new features,
+but that also means that there are changes that you should make ...</p>
+<p>Most notably, the library now uses separate storage drivers instead of
+always relying on (encrypted) cookies.
+In fact, cookies as storage have now been removed and you must always use
+some kind of server-side storage engine, with the file-system being the
+default option.</p>
+<p>The Session Class now utilizes PHP&#8217;s own mechanisms for building custom
+session handlers, which also means that your session data is now
+accessible via the <tt class="docutils literal"><span class="pre">$_SESSION</span></tt> superglobal (though, we&#8217;ve kept the
+possibility to use it as &#8220;userdata&#8221;, like you&#8217;ve done until now).</p>
+<p>A few configuration options have been removed and a few have been added.
+You should really read the whole <a class="reference internal" href="../libraries/sessions.html"><em>Session library manual</em></a> for the details, but here&#8217;s a short list of changes
+that you should make:</p>
+<blockquote>
+<div><ul>
+<li><p class="first">Set your <tt class="docutils literal"><span class="pre">$config['sess_driver']</span></tt> value</p>
+<p>It will default to &#8216;files&#8217;, unless you&#8217;ve previously used
+<tt class="docutils literal"><span class="pre">$config['sess_use_database']</span></tt>, in which case it will be set to
+&#8216;database&#8217;.</p>
+</li>
+<li><p class="first">Set a <tt class="docutils literal"><span class="pre">$config['sess_save_path']</span></tt> value</p>
+<p>For the &#8216;database&#8217; driver, a fallback to <tt class="docutils literal"><span class="pre">$config['sess_table_name']</span></tt>
+is in place, but otherwise requires you to read the manual for the
+specific driver of your choice.</p>
+</li>
+<li><p class="first">Update your <tt class="docutils literal"><span class="pre">ci_sessions</span></tt> table (&#8216;database&#8217; driver only)</p>
+<p>The table structure has changed a bit, and more specifically:</p>
+<blockquote>
+<div><ul class="simple">
+<li><tt class="docutils literal"><span class="pre">session_id</span></tt> field is renamed to <tt class="docutils literal"><span class="pre">id</span></tt></li>

+<p>This is accompanied by a slight change in the table indexes too, so

+<div class="admonition important">

+</div>
+</li>
+<li><p class="first">Remove <tt class="docutils literal"><span class="pre">$config['sess_match_useragent']</span></tt></p>
+<p>The user-agent string is input supplied by the user&#8217;s browser, or in
+other words: client side input. As such, it is an ineffective feature
+and hence why it has been removed.</p>
+</li>
+<li><p class="first">Remove <tt class="docutils literal"><span class="pre">$config['sess_encrypt_cookie']</span></tt></p>
+<p>As already noted, the library no longer uses cookies as a storage
+mechanism, which renders this option useless.</p>
+</li>
+<li><p class="first">Remove <tt class="docutils literal"><span class="pre">$config['sess_expire_on_close']</span></tt></p>
+<p>This option is still usable, but only for backwards compatibility
+purposes and it should be otherwise removed. The same effect is
+achieved by setting <tt class="docutils literal"><span class="pre">$config['sess_expiration']</span></tt> to 0.</p>
+</li>
+<li><p class="first">Check &#8220;flashdata&#8221; for collisions with &#8220;userdata&#8221;</p>
+<p>Flashdata is now just regular &#8220;userdata&#8221;, only marked for deletion on

+&#8220;flashdata&#8221; with the same name, because it&#8217;s the same thing.</p>
+</li>
+<li><p class="first">Check usage of session metadata</p>
+<p>Previously, you could access the &#8216;session_id&#8217;, &#8216;ip_address&#8217;,
+&#8216;user_agent&#8217; and &#8216;last_activity&#8217; metadata items as userdata.

+<li><p class="first">Check <tt class="docutils literal"><span class="pre">unset_userdata()</span></tt> usage</p>

+<h3>Routes containing :any<a class="headerlink" href="#routes-containing-any" title="Permalink to this headline">¶</a></h3>
+<p>Historically, CodeIgniter has always provided the <strong>:any</strong> wildcard in
+routing, with the intention of providing a way to match any character
+<strong>within</strong> an URI segment.</p>
+<p>However, the <strong>:any</strong> wildcard is actually just an alias for a regular
+expression and used to be executed in that manner as <strong>.+</strong>. This is
+considered a bug, as it also matches the / (forward slash) character, which
+is the URI segment delimiter and that was never the intention.</p>
+<p>In CodeIgniter 3, the <strong>:any</strong> wildcard will now represent <strong>[^/]+</strong>, so
+that it will not match a forward slash.</p>
+<p>There are certainly many developers that have utilized this bug as an actual
+feature. If you&#8217;re one of them and want to match a forward slash, please use
+the <strong>.+</strong> regular expression:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="p">(</span><span class="o">.+</span><span class="p">)</span>    <span class="c1">// matches ANYTHING</span>

+<p>As you should know, the <tt class="docutils literal"><span class="pre">$route['default_controller']</span></tt> and
+<tt class="docutils literal"><span class="pre">$route['404_override']</span></tt> settings accept not only a controller name, but
+also <em>controller/method</em> pairs. However, a bug in the routing logic has
+made it possible for some users to use that as <em>directory/controller</em>
+instead.</p>
+<p>As already said, this behavior was incidental and was never intended, nor
+documented. If you&#8217;ve relied on it, your application will break with
+CodeIgniter 3.0.</p>
+<p>Another notable change in version 3 is that &#8216;default_controller&#8217; and
+&#8216;404_override&#8217; are now applied <em>per directory</em>. To explain what this means,
+let&#8217;s take the following example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$route</span><span class="p">[</span><span class="s1">&#39;default_controller&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;main&#39;</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>Now, assuming that your website is located at <em>example.com</em>, you already
+know that if a user visits <tt class="docutils literal"><span class="pre">http://example.com/</span></tt>, the above setting will
+cause your &#8216;Main&#8217; controller to be loaded.</p>
+<p>However, what happens if you have an <em>application/controllers/admin/</em>
+directory and the user visits <tt class="docutils literal"><span class="pre">http://example.com/admin/</span></tt>?
+In CodeIgniter 3, the router will look for a &#8216;Main&#8217; controller under the
+admin/ directory as well. If not found, a Not Found (404) will be triggered.</p>
+<p>The same rule applies to the &#8216;404_override&#8217; setting.</p>

+<p>When <tt class="docutils literal"><span class="pre">$config['base_url']</span></tt> is not set, CodeIgniter tries to automatically

+<p>Auto-detection is never reliable and also has security implications, which
+is why you should <strong>always</strong> have it manually configured!</p>
+<p>One of the changes in CodeIgniter 3.0.3 is how this auto-detection works,
+and more specifically it now falls back to the server&#8217;s IP address instead
+of the hostname requested by the client. Therefore, if you&#8217;ve ever relied
+on auto-detection, it will change how your website works now.</p>
+<p>In case you need to allow e.g. multiple domains, or both <a class="reference external" href="http://">http://</a> and

+<p>When <tt class="docutils literal"><span class="pre">$config['base_url']</span></tt> is not set, CodeIgniter tries to automatically
+detect what your website&#8217;s base URL is. This is done purely for convenience
+when you are starting development of a new application.</p>
+<p>Auto-detection is never reliable and also has security implications, which
+is why you should <strong>always</strong> have it manually configured!</p>
+<p>One of the changes in CodeIgniter 3.0.3 is how this auto-detection works,
+and more specifically it now falls back to the server&#8217;s IP address instead
+of the hostname requested by the client. Therefore, if you&#8217;ve ever relied
+on auto-detection, it will change how your website works now.</p>
+<p>In case you need to allow e.g. multiple domains, or both <a class="reference external" href="http://">http://</a> and
+<a class="reference external" href="https://">https://</a> prefixes to be dynamically used depending on the request,
+remember that <em>application/config/config.php</em> is still a PHP script, in
+which you can create this logic with a few lines of code. For example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$allowed_domains</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;domain1.tld&#39;</span><span class="p">,</span> <span class="s1">&#39;domain2.tld&#39;</span><span class="p">);</span>

+<p>We&#8217;ve made some tweaks to the index.php file, mostly related to proper
+usage of directory separators (i.e. use the <tt class="docutils literal"><span class="pre">DIRECTORY_SEPARATOR</span></tt>
+constant instead of a hard coded forward slash &#8220;/&#8221;).</p>
+<p>Nothing will break if you skip this step, but if you&#8217;re running Windows
+or just want to be up to date with every change - we do recommend that
+you update your index.php file.</p>
+<p><em>Tip: Just copy the ``ENVIRONMENT``, ``$system_path``, ``$application_folder``
+and ``$view_folder`` declarations from the old file and put them into the
+new one, replacing the defaults.</em></p>

+<p>The <a class="reference internal" href="../libraries/form_validation.html"><em>Form Validation Library</em></a> has a
+<tt class="docutils literal"><span class="pre">prep_for_form()</span></tt> method, which is/can also be used as a rule in
+<tt class="docutils literal"><span class="pre">set_rules()</span></tt> to automatically perform HTML encoding on input data.</p>
+<p>Automatically encoding input (instead of output) data is a bad practice in
+the first place, and CodeIgniter and PHP itself offer other alternatives
+to this method anyway.
+For example, <a class="reference internal" href="../helpers/form_helper.html"><em>Form Helper</em></a> functions will
+automatically perform HTML escaping when necessary.</p>
+<p>Therefore, the <em>prep_for_form</em> method/rule is pretty much useless and is now
+deprecated and scheduled for removal in 3.1+.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>

+</div>
+<p>You&#8217;ll notice that it&#8217;s the same function used in the examples above to
+calculate the time between two point, except you are <strong>not</strong> using any
+parameters. When the parameters are absent, CodeIgniter does not stop
+the benchmark until right before the final output is sent to the
+browser. It doesn&#8217;t matter where you use the function call, the timer
+will continue to run until the very end.</p>
+<p>An alternate way to show your elapsed time in your view files is to use
+this pseudo-variable, if you prefer not to use the pure PHP:</p>

+<h3><a class="toc-backref" href="#id2">Initializing the Class</a><a class="headerlink" href="#initializing-the-class" title="Permalink to this headline">¶</a></h3>
+<p>Like most other classes in CodeIgniter, the Calendar class is
+initialized in your controller using the $this-&gt;load-&gt;library function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Once loaded, the Calendar object will be available using:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">calendar</span>

+<h3><a class="toc-backref" href="#id3">Displaying a Calendar</a><a class="headerlink" href="#displaying-a-calendar" title="Permalink to this headline">¶</a></h3>
+<p>Here is a very simple example showing how you can display a calendar:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>The above code will generate a calendar for the current month/year based
+on your server time. To show a calendar for a specific month and year
+you will pass this information to the calendar generating function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>The above code will generate a calendar showing the month of June in
+2006. The first parameter specifies the year, the second parameter
+specifies the month.</p>

+<h3><a class="toc-backref" href="#id4">Passing Data to your Calendar Cells</a><a class="headerlink" href="#passing-data-to-your-calendar-cells" title="Permalink to this headline">¶</a></h3>
+<p>To add data to your calendar cells involves creating an associative
+array in which the keys correspond to the days you wish to populate and
+the array value contains the data. The array is passed to the third
+parameter of the calendar generating function. Consider this example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>Using the above example, day numbers 3, 7, 13, and 26 will become links

+<h4><a class="toc-backref" href="#id7">What is a Row ID?</a><a class="headerlink" href="#what-is-a-row-id" title="Permalink to this headline">¶</a></h4>
+<p>The row ID is a unique identifier that is generated by the cart code
+when an item is added to the cart. The reason a unique ID is created
+is so that identical products with different options can be managed
+by the cart.</p>
+<p>For example, let&#8217;s say someone buys two identical t-shirts (same product
+ID), but in different sizes. The product ID (and other attributes) will
+be identical for both sizes because it&#8217;s the same shirt. The only
+difference will be the size. The cart must therefore have a means of
+identifying this difference so that the two sizes of shirts can be
+managed independently. It does so by creating a unique &#8220;row ID&#8221; based on
+the product ID and any options associated with it.</p>
+<p>In nearly all cases, updating the cart will be something the user does
+via the &#8220;view cart&#8221; page, so as a developer, it is unlikely that you
+will ever have to concern yourself with the &#8220;row ID&#8221;, other than making
+sure your &#8220;view cart&#8221; page contains this information in a hidden form
+field, and making sure it gets passed to the <tt class="docutils literal"><span class="pre">update()</span></tt> method when
+the update form is submitted. Please examine the construction of the
+&#8220;view cart&#8221; page above for more information.</p>

+<p>By default, CodeIgniter has one primary config file, located at
+application/config/config.php. If you open the file using your text
+editor you&#8217;ll see that config items are stored in an array called
+$config.</p>
+<p>You can add your own config items to this file, or if you prefer to keep
+your configuration items separate (assuming you even need config items),
+simply create your own file and save it in config folder.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">If you do create your own config files use the same format as
+the primary one, storing your items in an array called $config.
+CodeIgniter will intelligently manage these files so there will be no
+conflict even though the array has the same name (assuming an array
+index is not named the same as another).</p>

+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">CodeIgniter automatically loads the primary config file
+(application/config/config.php), so you will only need to load a config
+file if you have created your own.</p>
+</div>
+<p>There are two ways to load a config file:</p>
+<div class="section" id="manual-loading">
+<h4><a class="toc-backref" href="#id4">Manual Loading</a><a class="headerlink" href="#manual-loading" title="Permalink to this headline">¶</a></h4>
+<p>To load one of your custom config files you will use the following
+function within the <a class="reference internal" href="../general/controllers.html"><em>controller</em></a> that
+needs it:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="s1">&#39;filename&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Where filename is the name of your config file, without the .php file
+extension.</p>
+<p>If you need to load multiple config files normally they will be
+merged into one master config array. Name collisions can occur,
+however, if you have identically named array indexes in different
+config files. To avoid collisions you can set the second parameter to
+TRUE and each config file will be stored in an array index
+corresponding to the name of the config file. Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="c1">// Stored in an array with this prototype: $this-&gt;config[&#39;blog_settings&#39;] = $config</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="s1">&#39;blog_settings&#39;</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Please see the section entitled Fetching Config Items below to learn
+how to retrieve config items set this way.</p>
+<p>The third parameter allows you to suppress errors in the event that a
+config file does not exist:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="s1">&#39;blog_settings&#39;</span><span class="p">,</span> <span class="k">FALSE</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
+</pre></div>
+</div>
+</div>
+<div class="section" id="auto-loading">
+<h4><a class="toc-backref" href="#id5">Auto-loading</a><a class="headerlink" href="#auto-loading" title="Permalink to this headline">¶</a></h4>
+<p>If you find that you need a particular config file globally, you can
+have it loaded automatically by the system. To do this, open the
+<strong>autoload.php</strong> file, located at application/config/autoload.php,
+and add your config file as indicated in the file.</p>
+</div>
+</div>
+<div class="section" id="fetching-config-items">
+<h3><a class="toc-backref" href="#id6">Fetching Config Items</a><a class="headerlink" href="#fetching-config-items" title="Permalink to this headline">¶</a></h3>
+<p>To retrieve an item from your config file, use the following function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;item_name&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Where item_name is the $config array index you want to retrieve. For
+example, to fetch your language choice you&#8217;ll do this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$lang</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;language&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The function returns NULL if the item you are trying to fetch
+does not exist.</p>
+<p>If you are using the second parameter of the $this-&gt;config-&gt;load
+function in order to assign your config items to a specific index you
+can retrieve it by specifying the index name in the second parameter of
+the $this-&gt;config-&gt;item() function. Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="c1">// Loads a config file named blog_settings.php and assigns it to an index named &quot;blog_settings&quot;</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">load</span><span class="p">(</span><span class="s1">&#39;blog_settings&#39;</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
+
+<span class="c1">// Retrieve a config item named site_name contained within the blog_settings array</span>
+<span class="nv">$site_name</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;site_name&#39;</span><span class="p">,</span> <span class="s1">&#39;blog_settings&#39;</span><span class="p">);</span>
+
+<span class="c1">// An alternate way to specify the same item:</span>
+<span class="nv">$blog_config</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">config</span><span class="o">-&gt;</span><span class="na">item</span><span class="p">(</span><span class="s1">&#39;blog_settings&#39;</span><span class="p">);</span>

+<p>If you would like to dynamically set a config item or change an existing

+</pre></div>
+</div>
+<p>Where item_name is the $config array index you want to change, and
+item_value is its value.</p>
+</div>
+<div class="section" id="environments">
+<span id="config-environments"></span><h3><a class="toc-backref" href="#id8">Environments</a><a class="headerlink" href="#environments" title="Permalink to this headline">¶</a></h3>
+<p>You may load different configuration files depending on the current
+environment. The ENVIRONMENT constant is defined in index.php, and is
+described in detail in the <a class="reference internal" href="../general/environments.html"><em>Handling
+Environments</em></a> section.</p>
+<p>To create an environment-specific configuration file, create or copy a
+configuration file in application/config/{ENVIRONMENT}/{FILENAME}.php</p>
+<p>For example, to create a production-only config.php, you would:</p>
+<ol class="arabic simple">
+<li>Create the directory application/config/production/</li>
+<li>Copy your existing config.php into the above directory</li>
+<li>Edit application/config/production/config.php so it contains your
+production settings</li>
+</ol>
+<p>When you set the ENVIRONMENT constant to &#8216;production&#8217;, the settings for
+your new production-only config.php will be loaded.</p>
+<p>You can place the following configuration files in environment-specific
+folders:</p>
+<ul class="simple">
+<li>Default CodeIgniter configuration files</li>
+<li>Your own custom configuration files</li>
+</ul>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">CodeIgniter always loads the global config file first (i.e., the one in application/config/),
+then tries to load the configuration files for the current environment.
+This means you are not obligated to place <strong>all</strong> of your configuration files in an
+environment folder. Only the files that change per environment. Additionally you don&#8217;t
+have to copy <strong>all</strong> the config items in the environment config file. Only the config items
+that you wish to change for your environment. The config items declared in your environment
+folders always overwrite those in your global config files.</p>

+For example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;/path/to/photo1.jpg&#39;</span><span class="p">);</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;/path/to/photo2.jpg&#39;</span><span class="p">);</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;/path/to/photo3.jpg&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>To use the default disposition (attachment), leave the second parameter blank,
+otherwise use a custom disposition:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;image.jpg&#39;</span><span class="p">,</span> <span class="s1">&#39;inline&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>You can also use a URL:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;http://example.com/filename.pdf&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>If you&#8217;d like to use a custom file name, you can use the third parameter:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;filename.pdf&#39;</span><span class="p">,</span> <span class="s1">&#39;attachment&#39;</span><span class="p">,</span> <span class="s1">&#39;report.pdf&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>If you need to use a buffer string instead of a real - physical - file you can
+use the first parameter as buffer, the third parameter as file name and the fourth
+parameter as mime-type:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="nv">$buffer</span><span class="p">,</span> <span class="s1">&#39;attachment&#39;</span><span class="p">,</span> <span class="s1">&#39;report.pdf&#39;</span><span class="p">,</span> <span class="s1">&#39;application/pdf&#39;</span><span class="p">);</span>

+<p>A <em>key</em> is a piece of information that controls the cryptographic
+process and permits an encrypted string to be decoded. In fact, the key
+you chose will provide the <strong>only</strong> means to decode data that was
+encrypted with that key, so not only must you choose the key carefully,
+you must never change it if you intend use it for persistent data.</p>
+<p>It goes without saying that you should guard your key carefully. Should
+someone gain access to your key, the data will be easily decoded. If
+your server is not totally under your control it&#8217;s impossible to ensure
+key security so you may want to think carefully before using it for
+anything that requires high security, like storing credit card numbers.</p>
+<p>To take maximum advantage of the encryption algorithm, your key should
+be 32 characters in length (256 bits). The key should be as random a
+string as you can concoct, with numbers and uppercase and lowercase
+letters. Your key should <strong>not</strong> be a simple text string. In order to be
+cryptographically secure it needs to be as random as possible.</p>
+<p>Your key can be either stored in your <strong>application/config/config.php</strong>, or
+you can design your own storage mechanism and pass the key dynamically
+when encoding/decoding.</p>
+<p>To save your key to your <strong>application/config/config.php</strong>, open the file
+and set:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;encryption_key&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s2">&quot;YOUR KEY&quot;</span><span class="p">;</span>

+<h3><a class="toc-backref" href="#id3">Message Length</a><a class="headerlink" href="#message-length" title="Permalink to this headline">¶</a></h3>
+<p>It&#8217;s important for you to know that the encoded messages the encryption
+function generates will be approximately 2.6 times longer than the
+original message. For example, if you encrypt the string &#8220;my super
+secret data&#8221;, which is 21 characters in length, you&#8217;ll end up with an
+encoded string that is roughly 55 characters (we say &#8220;roughly&#8221; because
+the encoded string length increments in 64 bit clusters, so it&#8217;s not
+exactly linear). Keep this information in mind when selecting your data
+storage mechanism. Cookies, for example, can only hold 4K of
+information.</p>

+<div class="admonition note">

+<p>However, the <em>encryption_key</em> is not used as is.</p>
+<p>If you are somewhat familiar with cryptography, you should already know

+encryption and authentication is a bad practice.</p>
+<p>Because of that, two separate keys are derived from your already configured
+<em>encryption_key</em>: one for encryption and one for authentication. This is
+done via a technique called <a class="reference external" href="http://en.wikipedia.org/wiki/HKDF">HMAC-based Key Derivation Function</a> (HKDF).</p>

+<h3><a class="toc-backref" href="#id5">Setting your encryption_key</a><a class="headerlink" href="#setting-your-encryption-key" title="Permalink to this headline">¶</a></h3>
+<p>An <em>encryption key</em> is a piece of information that controls the
+cryptographic process and permits a plain-text string to be encrypted,
+and afterwards - decrypted. It is the secret &#8220;ingredient&#8221; in the whole
+process that allows you to be the only one who is able to decrypt data
+that you&#8217;ve decided to hide from the eyes of the public.
+After one key is used to encrypt data, that same key provides the <strong>only</strong>
+means to decrypt it, so not only must you chose one carefully, but you
+must not lose it or you will also lose access to the data.</p>
+<p>It must be noted that to ensure maximum security, such key <em>should</em> not
+only be as strong as possible, but also often changed. Such behavior
+however is rarely practical or possible to implement, and that is why
+CodeIgniter gives you the ability to configure a single key that is to be
+used (almost) every time.</p>
+<p>It goes without saying that you should guard your key carefully. Should
+someone gain access to your key, the data will be easily decrypted. If
+your server is not totally under your control it&#8217;s impossible to ensure
+key security so you may want to think carefully before using it for
+anything that requires high security, like storing credit card numbers.</p>
+<p>Your encryption key <strong>must</strong> be as long as the encyption algorithm in use
+allows. For AES-128, that&#8217;s 128 bits or 16 bytes (charcters) long.
+You will find a table below that shows the supported key lengths of
+different ciphers.</p>
+<p>The key should be as random as possible and it <strong>must not</strong> be a regular
+text string, nor the output of a hashing function, etc. In order to create
+a proper key, you must use the Encryption library&#8217;s <tt class="docutils literal"><span class="pre">create_key()</span></tt> method</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="c1">// $key will be assigned a 16-byte (128-bit) random key</span>
+<span class="nv">$key</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">encryption</span><span class="o">-&gt;</span><span class="na">create_key</span><span class="p">(</span><span class="mi">16</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The key can be either stored in your <em>application/config/config.php</em>, or
+you can design your own storage mechanism and pass the key dynamically
+when encrypting/decrypting.</p>
+<p>To save your key to your <em>application/config/config.php</em>, open the file
+and set:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;encryption_key&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;YOUR KEY&#39;</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>You&#8217;ll notice that the <tt class="docutils literal"><span class="pre">create_key()</span></tt> method outputs binary data, which
+is hard to deal with (i.e. a copy-paste may damage it), so you may use
+<tt class="docutils literal"><span class="pre">bin2hex()</span></tt>, <tt class="docutils literal"><span class="pre">hex2bin()</span></tt> or Base64-encoding to work with the key in
+a more friendly manner. For example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="c1">// Get a hex-encoded representation of the key:</span>
+<span class="nv">$key</span> <span class="o">=</span> <span class="nb">bin2hex</span><span class="p">(</span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">encryption</span><span class="o">-&gt;</span><span class="na">create_key</span><span class="p">(</span><span class="mi">16</span><span class="p">));</span>
+
+<span class="c1">// Put the same value in your config with hex2bin(),</span>

+<p>Uploading a file involves the following general process:</p>
+<ul class="simple">
+<li>An upload form is displayed, allowing a user to select a file and
+upload it.</li>
+<li>When the form is submitted, the file is uploaded to the destination
+you specify.</li>
+<li>Along the way, the file is validated to make sure it is allowed to be
+uploaded based on the preferences you set.</li>
+<li>Once uploaded, the user will be shown a success message.</li>
+</ul>
+<p>To demonstrate this process here is brief tutorial. Afterward you&#8217;ll
+find reference information.</p>

+File uploads require a multipart form, so the helper creates the proper

+<h3><a class="toc-backref" href="#id9">Setting Preferences</a><a class="headerlink" href="#setting-preferences" title="Permalink to this headline">¶</a></h3>
+<p>Similar to other libraries, you&#8217;ll control what is allowed to be upload
+based on your preferences. In the controller you built above you set the
+following preferences:</p>

+
+<span class="c1">// Alternately you can set preferences by calling the ``initialize()`` method. Useful if you auto-load the class:</span>

+<p>Before explaining CodeIgniter&#8217;s approach to data validation, let&#8217;s
+describe the ideal scenario:</p>
+<ol class="arabic simple">
+<li>A form is displayed.</li>
+<li>You fill it in and submit it.</li>
+<li>If you submitted something invalid, or perhaps missed a required
+item, the form is redisplayed containing your data along with an
+error message describing the problem.</li>
+<li>This process continues until you have submitted a valid form.</li>
+</ol>
+<p>On the receiving end, the script must:</p>
+<ol class="arabic simple">
+<li>Check for required data.</li>
+<li>Verify that the data is of the correct type, and meets the correct
+criteria. For example, if a username is submitted it must be
+validated to contain only permitted characters. It must be of a
+minimum length, and not exceed a maximum length. The username can&#8217;t
+be someone else&#8217;s existing username, or perhaps even a reserved word.
+Etc.</li>
+<li>Sanitize the data for security.</li>
+<li>Pre-format the data if needed (Does the data need to be trimmed? HTML
+encoded? Etc.)</li>
+<li>Prep the data for insertion in the database.</li>
+</ol>
+<p>Although there is nothing terribly complex about the above process, it
+usually requires a significant amount of code, and to display error
+messages, various control structures are usually placed within the form
+HTML. Form validation, while simple to create, is generally very messy
+and tedious to implement.</p>

+<h2><a class="toc-backref" href="#id8">Form Validation Tutorial</a><a class="headerlink" href="#form-validation-tutorial" title="Permalink to this headline">¶</a></h2>
+<p>What follows is a &#8220;hands on&#8221; tutorial for implementing CodeIgniters Form
+Validation.</p>
+<p>In order to implement form validation you&#8217;ll need three things:</p>
+<ol class="arabic simple">
+<li>A <a class="reference internal" href="../general/views.html"><em>View</em></a> file containing a form.</li>
+<li>A View file containing a &#8220;success&#8221; message to be displayed upon
+successful submission.</li>
+<li>A <a class="reference internal" href="../general/controllers.html"><em>controller</em></a> method to receive and
+process the submitted data.</li>
+</ol>
+<p>Let&#8217;s create those three things, using a member sign-up form as the
+example.</p>

+<ol class="arabic">
+<li><p class="first">It uses a form helper to create the form opening. Technically, this
+isn&#8217;t necessary. You could create the form using standard HTML.
+However, the benefit of using the helper is that it generates the
+action URL for you, based on the URL in your config file. This makes
+your application more portable in the event your URLs change.</p>
+</li>
+<li><p class="first">At the top of the form you&#8217;ll notice the following function call:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span> <span class="k">echo</span> <span class="nx">validation_errors</span><span class="p">();</span> <span class="cp">?&gt;</span>
+</pre></div>
+</div>
+<p>This function will return any error messages sent back by the
+validator. If there are no messages it returns an empty string.</p>
+</li>
+</ol>
+<p>The controller (Form.php) has one method: <tt class="docutils literal"><span class="pre">index()</span></tt>. This method
+initializes the validation class and loads the form helper and URL
+helper used by your view files. It also runs the validation routine.
+Based on whether the validation was successful it either presents the
+form or the success page.</p>
+</div>

+<span id="id1"></span><h3><a class="toc-backref" href="#id14">Setting Validation Rules</a><a class="headerlink" href="#setting-validation-rules" title="Permalink to this headline">¶</a></h3>
+<p>CodeIgniter lets you set as many validation rules as you need for a
+given field, cascading them in order, and it even lets you prep and
+pre-process the field data at the same time. To set validation rules you
+will use the <tt class="docutils literal"><span class="pre">set_rules()</span></tt> method:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">form_validation</span><span class="o">-&gt;</span><span class="na">set_rules</span><span class="p">();</span>
+</pre></div>
+</div>
+<p>The above method takes <strong>three</strong> parameters as input:</p>
+<ol class="arabic simple">
+<li>The field name - the exact name you&#8217;ve given the form field.</li>
+<li>A &#8220;human&#8221; name for this field, which will be inserted into the error
+message. For example, if your field is named &#8220;user&#8221; you might give it
+a human name of &#8220;Username&#8221;.</li>
+<li>The validation rules for this form field.</li>
+<li>(optional) Set custom error messages on any rules given for current field. If not provided will use the default one.</li>
+</ol>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>

+<p>The validation system supports callbacks to your own validation
+methods. This permits you to extend the validation class to meet your
+needs. For example, if you need to run a database query to see if the
+user is choosing a unique username, you can create a callback method
+that does that. Let&#8217;s create an example of this.</p>
+<p>In your controller, change the &#8220;username&#8221; rule to this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">form_validation</span><span class="o">-&gt;</span><span class="na">set_rules</span><span class="p">(</span><span class="s1">&#39;username&#39;</span><span class="p">,</span> <span class="s1">&#39;Username&#39;</span><span class="p">,</span> <span class="s1">&#39;callback_username_check&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Then add a new method called <tt class="docutils literal"><span class="pre">username_check()</span></tt> to your controller.

+<p>Reload your form and submit it with the word &#8220;test&#8221; as the username. You
+can see that the form field data was passed to your callback method
+for you to process.</p>
+<p>To invoke a callback just put the method name in a rule, with
+&#8220;callback_&#8221; as the rule <strong>prefix</strong>. If you need to receive an extra
+parameter in your callback method, just add it normally after the
+method name between square brackets, as in: <tt class="docutils literal"><span class="pre">callback_foo[bar]</span></tt>,
+then it will be passed as the second argument of your callback method.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">You can also process the form data that is passed to your
+callback and return it. If your callback returns anything other than a

+form data.</p>

+<p>If callback rules aren&#8217;t good enough for you (for example, because they are
+limited to your controller), don&#8217;t get disappointed, there&#8217;s one more way
+to create custom rules: anything that <tt class="docutils literal"><span class="pre">is_callable()</span></tt> would return TRUE for.</p>
+<p>Consider the following example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">form_validation</span><span class="o">-&gt;</span><span class="na">set_rules</span><span class="p">(</span>
+        <span class="s1">&#39;username&#39;</span><span class="p">,</span> <span class="s1">&#39;Username&#39;</span><span class="p">,</span>
+        <span class="k">array</span><span class="p">(</span>
+                <span class="s1">&#39;required&#39;</span><span class="p">,</span>

+        <span class="p">)</span>
+<span class="p">);</span>
+</pre></div>
+</div>
+<p>The above code would use the <tt class="docutils literal"><span class="pre">valid_username()</span></tt> method from your
+<tt class="docutils literal"><span class="pre">Users_model</span></tt> object.</p>
+<p>This is just an example of course, and callbacks aren&#8217;t limited to models.
+You can use any object/method that accepts the field value as its&#8217; first
+parameter. You can also use an anonymous function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">form_validation</span><span class="o">-&gt;</span><span class="na">set_rules</span><span class="p">(</span>
+        <span class="s1">&#39;username&#39;</span><span class="p">,</span> <span class="s1">&#39;Username&#39;</span><span class="p">,</span>
+        <span class="k">array</span><span class="p">(</span>
+                <span class="s1">&#39;required&#39;</span><span class="p">,</span>
+                <span class="k">function</span><span class="p">(</span><span class="nv">$value</span><span class="p">)</span>

+        <span class="p">)</span>
+<span class="p">);</span>
+</pre></div>
+</div>
+<p>Of course, since a Callable rule by itself is not a string, it isn&#8217;t
+a rule name either. That is a problem when you want to set error messages
+for them. In order to get around that problem, you can put such rules as
+the second element of an array, with the first one being the rule name:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">form_validation</span><span class="o">-&gt;</span><span class="na">set_rules</span><span class="p">(</span>

+<p>The Form Validation class supports the use of arrays as field names.
+Consider this example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">input</span> <span class="nx">type</span><span class="o">=</span><span class="s2">&quot;text&quot;</span> <span class="nx">name</span><span class="o">=</span><span class="s2">&quot;options[]&quot;</span> <span class="nx">value</span><span class="o">=</span><span class="s2">&quot;&quot;</span> <span class="nx">size</span><span class="o">=</span><span class="s2">&quot;50&quot;</span> <span class="o">/&gt;</span>
+</pre></div>
+</div>
+<p>If you do use an array as a field name, you must use the EXACT array
+name in the <a class="reference internal" href="#helper-functions"><em>Helper Functions</em></a> that require the
+field name, and as your Validation Rule field name.</p>
+<p>For example, to set a rule for the above field you would use:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">form_validation</span><span class="o">-&gt;</span><span class="na">set_rules</span><span class="p">(</span><span class="s1">&#39;options[]&#39;</span><span class="p">,</span> <span class="s1">&#39;Options&#39;</span><span class="p">,</span> <span class="s1">&#39;required&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Or, to show an error for the above field you would use:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span> <span class="k">echo</span> <span class="nx">form_error</span><span class="p">(</span><span class="s1">&#39;options[]&#39;</span><span class="p">);</span> <span class="cp">?&gt;</span>
+</pre></div>
+</div>
+<p>Or to re-populate the field you would use:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">input</span> <span class="nx">type</span><span class="o">=</span><span class="s2">&quot;text&quot;</span> <span class="nx">name</span><span class="o">=</span><span class="s2">&quot;options[]&quot;</span> <span class="nx">value</span><span class="o">=</span><span class="s2">&quot;&lt;?php echo set_value(&#39;options[]&#39;); ?&gt;&quot;</span> <span class="nx">size</span><span class="o">=</span><span class="s2">&quot;50&quot;</span> <span class="o">/&gt;</span>
+</pre></div>
+</div>
+<p>You can use multidimensional arrays as field names as well. For example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">input</span> <span class="nx">type</span><span class="o">=</span><span class="s2">&quot;text&quot;</span> <span class="nx">name</span><span class="o">=</span><span class="s2">&quot;options[size]&quot;</span> <span class="nx">value</span><span class="o">=</span><span class="s2">&quot;&quot;</span> <span class="nx">size</span><span class="o">=</span><span class="s2">&quot;50&quot;</span> <span class="o">/&gt;</span>
+</pre></div>
+</div>
+<p>Or even:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">input</span> <span class="nx">type</span><span class="o">=</span><span class="s2">&quot;text&quot;</span> <span class="nx">name</span><span class="o">=</span><span class="s2">&quot;sports[nba][basketball]&quot;</span> <span class="nx">value</span><span class="o">=</span><span class="s2">&quot;&quot;</span> <span class="nx">size</span><span class="o">=</span><span class="s2">&quot;50&quot;</span> <span class="o">/&gt;</span>
+</pre></div>
+</div>
+<p>As with our first example, you must use the exact array name in the
+helper functions:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span> <span class="k">echo</span> <span class="nx">form_error</span><span class="p">(</span><span class="s1">&#39;sports[nba][basketball]&#39;</span><span class="p">);</span> <span class="cp">?&gt;</span>
+</pre></div>
+</div>
+<p>If you are using checkboxes (or other fields) that have multiple
+options, don&#8217;t forget to leave an empty bracket after each option, so
+that all selections will be added to the POST array:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">input</span> <span class="nx">type</span><span class="o">=</span><span class="s2">&quot;checkbox&quot;</span> <span class="nx">name</span><span class="o">=</span><span class="s2">&quot;options[]&quot;</span> <span class="nx">value</span><span class="o">=</span><span class="s2">&quot;red&quot;</span> <span class="o">/&gt;</span>
+<span class="o">&lt;</span><span class="nx">input</span> <span class="nx">type</span><span class="o">=</span><span class="s2">&quot;checkbox&quot;</span> <span class="nx">name</span><span class="o">=</span><span class="s2">&quot;options[]&quot;</span> <span class="nx">value</span><span class="o">=</span><span class="s2">&quot;blue&quot;</span> <span class="o">/&gt;</span>
+<span class="o">&lt;</span><span class="nx">input</span> <span class="nx">type</span><span class="o">=</span><span class="s2">&quot;checkbox&quot;</span> <span class="nx">name</span><span class="o">=</span><span class="s2">&quot;options[]&quot;</span> <span class="nx">value</span><span class="o">=</span><span class="s2">&quot;green&quot;</span> <span class="o">/&gt;</span>
+</pre></div>
+</div>
+<p>Or if you use a multidimensional array:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">input</span> <span class="nx">type</span><span class="o">=</span><span class="s2">&quot;checkbox&quot;</span> <span class="nx">name</span><span class="o">=</span><span class="s2">&quot;options[color][]&quot;</span> <span class="nx">value</span><span class="o">=</span><span class="s2">&quot;red&quot;</span> <span class="o">/&gt;</span>

+</pre></div>
+</div>
+<p>When you use a helper function you&#8217;ll include the bracket as well:</p>

+<li>Image Cropping</li>
+<li>Image Rotating</li>

+<p>Like most other classes in CodeIgniter, the image class is initialized
+in your controller using the $this-&gt;load-&gt;library function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;image_lib&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Once the library is loaded it will be ready for use. The image library
+object you will use to call all functions is: <tt class="docutils literal"><span class="pre">$this-&gt;image_lib</span></tt></p>

+<h3><a class="toc-backref" href="#id2">Processing an Image</a><a class="headerlink" href="#processing-an-image" title="Permalink to this headline">¶</a></h3>
+<p>Regardless of the type of processing you would like to perform
+(resizing, cropping, rotation, or watermarking), the general process is
+identical. You will set some preferences corresponding to the action you
+intend to perform, then call one of four available processing functions.
+For example, to create an image thumbnail you&#8217;ll do this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">&#39;image_library&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;gd2&#39;</span><span class="p">;</span>

+</pre></div>
+</div>
+<p>The above code tells the image_resize function to look for an image
+called <em>mypic.jpg</em> located in the source_image folder, then create a
+thumbnail that is 75 X 50 pixels using the GD2 image_library. Since the
+maintain_ratio option is enabled, the thumb will be as close to the
+target width and height as possible while preserving the original aspect
+ratio. The thumbnail will be called <em>mypic_thumb.jpg</em> and located at
+the same level as <em>source_image</em>.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">In order for the image class to be allowed to do any

+<div class="section" id="processing-methods">
+<h3><a class="toc-backref" href="#id3">Processing Methods</a><a class="headerlink" href="#processing-methods" title="Permalink to this headline">¶</a></h3>
+<p>There are four available processing methods:</p>
+<ul class="simple">
+<li>$this-&gt;image_lib-&gt;resize()</li>
+<li>$this-&gt;image_lib-&gt;crop()</li>
+<li>$this-&gt;image_lib-&gt;rotate()</li>
+<li>$this-&gt;image_lib-&gt;watermark()</li>
+</ul>
+<p>These methods return boolean TRUE upon success and FALSE for failure.
+If they fail you can retrieve the error message using this function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">image_lib</span><span class="o">-&gt;</span><span class="na">display_errors</span><span class="p">();</span>
+</pre></div>
+</div>
+<p>A good practice is to use the processing function conditionally, showing an
+error upon failure, like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">if</span> <span class="p">(</span> <span class="o">!</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">image_lib</span><span class="o">-&gt;</span><span class="na">resize</span><span class="p">())</span>

+<span class="p">}</span>
+</pre></div>
+</div>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p>You can optionally specify the HTML formatting to be applied to
+the errors, by submitting the opening/closing tags in the function,
+like this:</p>

+<li><strong>Text</strong>: The watermark message will be generated using text, either

+your GD installation must be compiled with True Type support (most

+<p>The image rotation method requires that the angle of rotation be set
+via its preference:</p>

+<p>There are 5 rotation options:</p>

+<li>180 - rotates counter-clockwise by 180 degrees.</li>
+<li>270 - rotates counter-clockwise by 270 degrees.</li>
+<li>hor - flips the image horizontally.</li>

+<p>CodeIgniter comes with helper methods that let you fetch POST, GET,
+COOKIE or SERVER items. The main advantage of using the provided
+methods rather than fetching an item directly (<tt class="docutils literal"><span class="pre">$_POST['something']</span></tt>)
+is that the methods will check to see if the item is set and return
+NULL if not. This lets you conveniently use data without
+having to test whether an item exists first. In other words, normally
+you might do something like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$something</span> <span class="o">=</span> <span class="nb">isset</span><span class="p">(</span><span class="nv">$_POST</span><span class="p">[</span><span class="s1">&#39;something&#39;</span><span class="p">])</span> <span class="o">?</span> <span class="nv">$_POST</span><span class="p">[</span><span class="s1">&#39;something&#39;</span><span class="p">]</span> <span class="o">:</span> <span class="k">NULL</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>With CodeIgniter&#8217;s built in methods you can simply do this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$something</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">input</span><span class="o">-&gt;</span><span class="na">post</span><span class="p">(</span><span class="s1">&#39;something&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The main methods are:</p>
+<ul class="simple">
+<li><tt class="docutils literal"><span class="pre">$this-&gt;input-&gt;post()</span></tt></li>
+<li><tt class="docutils literal"><span class="pre">$this-&gt;input-&gt;get()</span></tt></li>

+<h3><a class="toc-backref" href="#id6">Using the php://input stream</a><a class="headerlink" href="#using-the-php-input-stream" title="Permalink to this headline">¶</a></h3>
+<p>If you want to utilize the PUT, DELETE, PATCH or other exotic request
+methods, they can only be accessed via a special input stream, that
+can only be read once. This isn&#8217;t as easy as just reading from e.g.
+the <tt class="docutils literal"><span class="pre">$_POST</span></tt> array, because it will always exist and you can try
+and access multiple variables without caring that you might only have
+one shot at all of the POST data.</p>
+<p>CodeIgniter will take care of that for you, and you can read the data
+from the <strong>php://input</strong> stream at any time, just by using the
+<tt class="docutils literal"><span class="pre">$raw_input_stream</span></tt> property:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">input</span><span class="o">-&gt;</span><span class="na">raw_input_stream</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>Additionally if the input stream is form-encoded like $_POST you can
+access its values by calling the
+<tt class="docutils literal"><span class="pre">input_stream()</span></tt> method:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">input</span><span class="o">-&gt;</span><span class="na">input_stream</span><span class="p">(</span><span class="s1">&#39;key&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Similar to other methods such as <tt class="docutils literal"><span class="pre">get()</span></tt> and <tt class="docutils literal"><span class="pre">post()</span></tt>, if the
+requested data is not found, it will return NULL and you can also
+decide whether to run the data through <tt class="docutils literal"><span class="pre">xss_clean()</span></tt> by passing
+a boolean value as the second parameter:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">input</span><span class="o">-&gt;</span><span class="na">input_stream</span><span class="p">(</span><span class="s1">&#39;key&#39;</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span> <span class="c1">// XSS Clean</span>

+<p>Sets a cookie containing the values you specify. There are two ways to
+pass information to this method so that a cookie can be set: Array
+Method, and Discrete Parameters:</p>
+<p><strong>Array Method</strong></p>
+<p>Using this method, an associative array is passed to the first
+parameter:</p>

+</pre></div>
+</div>
+<p><strong>Notes</strong></p>
+<p>Only the name and value are required. To delete a cookie set it with the
+expiration blank.</p>
+<p>The expiration is set in <strong>seconds</strong>, which will be added to the current
+time. Do not include the time, but rather only the number of seconds
+from <em>now</em> that you wish the cookie to be valid. If the expiration is
+set to zero the cookie will only last as long as the browser is open.</p>
+<p>For site-wide cookies regardless of how your site is requested, add your
+URL to the <strong>domain</strong> starting with a period, like this:
+.your-domain.com</p>
+<p>The path is usually not needed since the method sets a root path.</p>
+<p>The prefix is only needed if you need to avoid name collisions with
+other identically named cookies for your server.</p>
+<p>The <em>httponly</em> and <em>secure</em> flags, when omitted, will default to your
+<tt class="docutils literal"><span class="pre">$config['cookie_httponly']</span></tt> and <tt class="docutils literal"><span class="pre">$config['cookie_secure']</span></tt> settings.</p>
+<p><strong>Discrete Parameters</strong></p>
+<p>If you prefer, you can set the cookie by passing data using individual
+parameters:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">input</span><span class="o">-&gt;</span><span class="na">set_cookie</span><span class="p">(</span><span class="nv">$name</span><span class="p">,</span> <span class="nv">$value</span><span class="p">,</span> <span class="nv">$expire</span><span class="p">,</span> <span class="nv">$domain</span><span class="p">,</span> <span class="nv">$path</span><span class="p">,</span> <span class="nv">$prefix</span><span class="p">,</span> <span class="nv">$secure</span><span class="p">);</span>

+<p>CodeIgniter provides a library to help you with certain common functions
+that you may want to use with Javascript. Please note that CodeIgniter
+does not require the jQuery library to run, and that any scripting
+library will work equally well. The jQuery library is simply presented
+as a convenience if you choose to use it.</p>

+<p>To initialize the Javascript class manually in your controller
+constructor, use the <tt class="docutils literal"><span class="pre">$this-&gt;load-&gt;library()</span></tt> method. Currently,
+the only available library is jQuery, which will automatically be
+loaded like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;javascript&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The Javascript class also accepts parameters:</p>
+<ul class="simple">
+<li>js_library_driver (string) <em>default: &#8216;jquery&#8217;</em></li>
+<li>autoload (bool) <em>default: TRUE</em></li>
+</ul>
+<p>You may override the defaults by sending an associative array:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span>
+        <span class="s1">&#39;javascript&#39;</span><span class="p">,</span>
+        <span class="k">array</span><span class="p">(</span>
+                <span class="s1">&#39;js_library_driver&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;scripto&#39;</span><span class="p">,</span>

+        <span class="p">)</span>
+<span class="p">);</span>
+</pre></div>
+</div>
+<p>Again, presently only &#8216;jquery&#8217; is available. You may wish to set
+autoload to FALSE, though, if you do not want the jQuery library to
+automatically include a script tag for the main jQuery script file. This
+is useful if you are loading it from a location outside of CodeIgniter,
+or already have the script tag in your markup.</p>
+<p>Once loaded, the jQuery library object will be available using:</p>

+<p>The Language Class provides functions to retrieve language files and
+lines of text for purposes of internationalization.</p>
+<p>In your CodeIgniter <strong>system</strong> folder, you will find a <strong>language</strong> sub-directory
+containing a set of language files for the <strong>english</strong> idiom.
+The files in this directory (<strong>system/language/english/</strong>) define the regular messages,
+error messages, and other generally output terms or expressions, for the different parts
+of the CodeIgniter framework.</p>
+<p>You can create or incorporate your own language files, as needed, in order to provide
+application-specific error and other messages, or to provide translations of the core
+messages into other languages. These translations or additional messages would go inside
+your <strong>application/language/</strong> directory, with separate sub-directories for each idiom
+(for instance, &#8216;french&#8217; or &#8216;german&#8217;).</p>
+<p>The CodeIgniter framework comes with a set of language files for the &#8220;english&#8221; idiom.
+Additional approved translations for different idioms may be found in the
+<a class="reference external" href="https://github.com/bcit-ci/codeigniter3-translations">CodeIgniter 3 Translations repositories</a>.
+Each repository deals with a single idiom.</p>
+<p>When CodeIgniter loads language files, it will load the one in <strong>system/language/</strong>
+first and will then look for an override in your <strong>application/language/</strong> directory.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">Each language should be stored in its own folder. For example,
+the English files are located at: system/language/english</p>

+<p>An application package allows for the easy distribution of complete sets
+of resources in a single directory, complete with its own libraries,
+models, helpers, config, and language files. It is recommended that
+these packages be placed in the application/third_party directory. Below

+<p>Whatever the purpose of the &#8220;Foo Bar&#8221; application package, it has its
+own config files, helpers, language files, libraries, and models. To use
+these resources in your controllers, you first need to tell the Loader
+that you are going to be loading resources from a package, by adding the
+package path via the <tt class="docutils literal"><span class="pre">add_package_path()</span></tt> method.</p>

+<h3><a class="toc-backref" href="#id3">Package view files</a><a class="headerlink" href="#package-view-files" title="Permalink to this headline">¶</a></h3>
+<p>By Default, package view files paths are set when <tt class="docutils literal"><span class="pre">add_package_path()</span></tt>
+is called. View paths are looped through, and once a match is
+encountered that view is loaded.</p>
+<p>In this instance, it is possible for view naming collisions within
+packages to occur, and possibly the incorrect package being loaded. To
+ensure against this, set an optional second parameter of FALSE when
+calling <tt class="docutils literal"><span class="pre">add_package_path()</span></tt>.</p>

+<p>This method is used to load driver libraries, acts very much like the

+<p>As an example, if you would like to use sessions with CodeIgniter, the first

+</pre></div>
+</div>
+<p>Once loaded, the library will be ready for use, using <tt class="docutils literal"><span class="pre">$this-&gt;session</span></tt>.</p>
+<p>Driver files must be stored in a subdirectory within the main
+&#8220;libraries&#8221; directory, or within your personal <em>application/libraries</em>
+directory. The subdirectory must match the parent class name. Read the
+<a class="reference internal" href="../general/drivers.html"><em>Drivers</em></a> description for details.</p>

+<h1>Migrations Class<a class="headerlink" href="#migrations-class" title="Permalink to this headline">¶</a></h1>
+<p>Migrations are a convenient way for you to alter your database in a
+structured and organized manner. You could edit fragments of SQL by hand
+but you would then be responsible for telling other developers that they
+need to go and run them. You would also have to keep track of which changes
+need to be run against the production machines next time you deploy.</p>
+<p>The database table <strong>migration</strong> tracks which migrations have already been
+run so all you have to do is update your application files and
+call <tt class="docutils literal"><span class="pre">$this-&gt;migration-&gt;current()</span></tt> to work out which migrations should be run.
+The current version is found in <strong>application/config/migration.php</strong>.</p>

+<p>Each Migration is run in numeric order forward or backwards depending on the
+method taken. Two numbering styles are available:</p>
+<ul class="simple">
+<li><strong>Sequential:</strong> each migration is numbered in sequence, starting with <strong>001</strong>.
+Each number must be three digits, and there must not be any gaps in the
+sequence. (This was the numbering scheme prior to CodeIgniter 3.0.)</li>
+<li><strong>Timestamp:</strong> each migration is numbered using the timestamp when the migration
+was created, in <strong>YYYYMMDDHHIISS</strong> format (e.g. <strong>20121031100537</strong>). This
+helps prevent numbering conflicts when working in a team environment, and is
+the preferred scheme in CodeIgniter 3.0 and later.</li>
+</ul>
+<p>The desired style may be selected using the <tt class="docutils literal"><span class="pre">$config['migration_type']</span></tt>
+setting in your <em>application/config/migration.php</em> file.</p>
+<p>Regardless of which numbering style you choose to use, prefix your migration
+files with the migration number followed by an underscore and a descriptive
+name for the migration. For example:</p>
+<ul class="simple">
+<li>001_add_blog.php (sequential numbering)</li>
+<li>20121031100537_add_blog.php (timestamp numbering)</li>

+<p>This will be the first migration for a new site which has a blog. All
+migrations go in the <strong>application/migrations/</strong> directory and have names such
+as <em>20121031100537_add_blog.php</em>.</p>

+it works transparently without your intervention. For example, when you
+use the <a class="reference internal" href="loader.html"><em>Loader</em></a> class to load a view file,
+it&#8217;s automatically passed to the Output class, which will be called
+automatically by CodeIgniter at the end of system execution. It is

+<p>The <tt class="docutils literal"><span class="pre">$config</span></tt> array contains your configuration variables. It is passed to
+the <tt class="docutils literal"><span class="pre">$this-&gt;pagination-&gt;initialize()</span></tt> method as shown above. Although
+there are some twenty items you can configure, at minimum you need the
+three shown. Here is a description of what those items represent:</p>
+<ul class="simple">
+<li><strong>base_url</strong> This is the full URL to the controller class/function
+containing your pagination. In the example above, it is pointing to a
+controller called &#8220;Test&#8221; and a function called &#8220;page&#8221;. Keep in mind
+that you can <a class="reference internal" href="../general/routing.html"><em>re-route your URI</em></a> if you
+need a different structure.</li>
+<li><strong>total_rows</strong> This number represents the total rows in the result
+set you are creating pagination for. Typically this number will be
+the total rows that your database query returned.</li>
+<li><strong>per_page</strong> The number of items you intend to show per page. In the
+above example, you would be showing 20 items per page.</li>
+</ul>
+<p>The <tt class="docutils literal"><span class="pre">create_links()</span></tt> method returns an empty string when there is no
+pagination to show.</p>

+<p>If you prefer not to set preferences using the above method, you can
+instead put them into a config file. Simply create a new file called
+pagination.php, add the <tt class="docutils literal"><span class="pre">$config</span></tt> array in that file. Then save the file
+in <em>application/config/pagination.php</em> and it will be used automatically.
+You will NOT need to use <tt class="docutils literal"><span class="pre">$this-&gt;pagination-&gt;initialize()</span></tt> if you save

+<p>The following is a list of all the preferences you can pass to the
+initialization function to tailor the display.</p>
+<p><strong>$config[&#8216;uri_segment&#8217;] = 3;</strong></p>
+<p>The pagination function automatically determines which segment of your
+URI contains the page number. If you need something different you can
+specify it.</p>
+<p><strong>$config[&#8216;num_links&#8217;] = 2;</strong></p>
+<p>The number of &#8220;digit&#8221; links you would like before and after the selected
+page number. For example, the number 2 will place two digits on either
+side, as in the example links at the very top of this page.</p>
+<p><strong>$config[&#8216;use_page_numbers&#8217;] = TRUE;</strong></p>
+<p>By default, the URI segment will use the starting index for the items
+you are paginating. If you prefer to show the the actual page number,
+set this to TRUE.</p>
+<p><strong>$config[&#8216;page_query_string&#8217;] = TRUE;</strong></p>
+<p>By default, the pagination library assume you are using <a class="reference internal" href="../general/urls.html"><em>URI
+Segments</em></a>, and constructs your links something
+like:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">test</span><span class="o">/</span><span class="nx">page</span><span class="o">/</span><span class="mi">20</span>
+</pre></div>
+</div>
+<p>If you have <tt class="docutils literal"><span class="pre">$config['enable_query_strings']</span></tt> set to TRUE your links
+will automatically be re-written using Query Strings. This option can
+also be explicitly set. Using <tt class="docutils literal"><span class="pre">$config['page_query_string']</span></tt> set to TRUE,
+the pagination link will become:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">?</span><span class="nx">c</span><span class="o">=</span><span class="nx">test</span><span class="o">&amp;</span><span class="nx">m</span><span class="o">=</span><span class="nx">page</span><span class="o">&amp;</span><span class="nx">per_page</span><span class="o">=</span><span class="mi">20</span>
+</pre></div>
+</div>
+<p>Note that &#8220;per_page&#8221; is the default query string passed, however can be
+configured using <tt class="docutils literal"><span class="pre">$config['query_string_segment']</span> <span class="pre">=</span> <span class="pre">'your_string'</span></tt></p>
+<p><strong>$config[&#8216;reuse_query_string&#8217;] = FALSE;</strong></p>
+<p>By default your Query String arguments (nothing to do with other
+query string options) will be ignored. Setting this config to
+TRUE will add existing query string arguments back into the
+URL after the URI segment and before the suffix.:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">test</span><span class="o">/</span><span class="nx">page</span><span class="o">/</span><span class="mi">20</span><span class="o">?</span><span class="nx">query</span><span class="o">=</span><span class="nx">search</span><span class="o">%</span><span class="nx">term</span>
+</pre></div>
+</div>
+<p>This helps you mix together normal <a class="reference internal" href="../general/urls.html"><em>URI Segments</em></a>
+as well as query string arguments, which until 3.0 was not possible.</p>
+<p><strong>$config[&#8216;prefix&#8217;] = &#8216;&#8217;;</strong></p>
+<p>A custom prefix added to the path. The prefix value will be right before
+the offset segment.</p>
+<p><strong>$config[&#8216;suffix&#8217;] = &#8216;&#8217;;</strong></p>
+<p>A custom suffix added to the path. The sufix value will be right after
+the offset segment.</p>
+<p><strong>$config[&#8216;use_global_url_suffix&#8217;] = FALSE;</strong></p>
+<p>When set to TRUE, it will <strong>override</strong> the <tt class="docutils literal"><span class="pre">$config['suffix']</span></tt> value and
+instead set it to the one that you have in <tt class="docutils literal"><span class="pre">$config['url_suffix']</span></tt> in

+<p>The first parameter contains the name of the <a class="reference internal" href="../general/views.html"><em>view

+blog_template.php), and the second parameter contains an associative
+array of data to be replaced in the template. In the above example, the
+template would contain two variables: {blog_title} and {blog_heading}</p>
+<p>There is no need to &#8220;echo&#8221; or do something with the data returned by
+$this-&gt;parser-&gt;parse(). It is automatically passed to the output class
+to be sent to the browser. However, if you do want the data returned
+instead of sent to the output class you can pass TRUE (boolean) as the
+third parameter:</p>

+<p>CodeIgniter comes with a Cross Site Scripting prevention filter, which
+looks for commonly used techniques to trigger JavaScript or other types
+of code that attempt to hijack cookies or do other malicious things.
+If anything disallowed is encountered it is rendered safe by converting
+the data to character entities.</p>
+<p>To filter data through the XSS filter use the <tt class="docutils literal"><span class="pre">xss_clean()</span></tt> method:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$data</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">security</span><span class="o">-&gt;</span><span class="na">xss_clean</span><span class="p">(</span><span class="nv">$data</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>An optional second parameter, <em>is_image</em>, allows this function to be used
+to test images for potential XSS attacks, useful for file upload
+security. When this second parameter is set to TRUE, instead of
+returning an altered string, the function returns TRUE if the image is
+safe, and FALSE if it contained potentially malicious information that a
+browser may attempt to execute.</p>

+may alter this behavior by editing the following config parameter</p>

+<p>Sessions will typically run globally with each page load, so the Session
+class should either be initialized in your <a class="reference internal" href="../general/controllers.html"><em>controller</em></a> constructors, or it can be <a class="reference internal" href="../general/autoloader.html"><em>auto-loaded</em></a> by the system.
+For the most part the session class will run unattended in the background,
+so simply initializing the class will cause it to read, create, and update
+sessions when necessary.</p>
+<p>To initialize the Session class manually in your controller constructor,
+use the <tt class="docutils literal"><span class="pre">$this-&gt;load-&gt;library()</span></tt> method:</p>

+<p>When a page is loaded, the session class will check to see if valid
+session cookie is sent by the user&#8217;s browser. If a sessions cookie does
+<strong>not</strong> exist (or if it doesn&#8217;t match one stored on the server or has
+expired) a new session will be created and saved.</p>
+<p>If a valid session does exist, its information will be updated. With each
+update, the session ID may be regenerated if configured to do so.</p>
+<p>It&#8217;s important for you to understand that once initialized, the Session
+class runs automatically. There is nothing you need to do to cause the
+above behavior to happen. You can, as you&#8217;ll see below, work with session
+data, but the process of reading, writing, and updating a session is
+automatic.</p>

+<h4><a class="toc-backref" href="#id6">A note about concurrency</a><a class="headerlink" href="#a-note-about-concurrency" title="Permalink to this headline">¶</a></h4>
+<p>Unless you&#8217;re developing a website with heavy AJAX usage, you can skip this
+section. If you are, however, and if you&#8217;re experiencing performance
+issues, then this note is exactly what you&#8217;re looking for.</p>
+<p>Sessions in previous versions of CodeIgniter didn&#8217;t implement locking,
+which meant that two HTTP requests using the same session could run exactly
+at the same time. To use a more appropriate technical term - requests were
+non-blocking.</p>
+<p>However, non-blocking requests in the context of sessions also means
+unsafe, because modifications to session data (or session ID regeneration)
+in one request can interfere with the execution of a second, concurrent
+request. This detail was at the root of many issues and the main reason why
+CodeIgniter 3.0 has a completely re-written Session library.</p>
+<p>Why are we telling you this? Because it is likely that after trying to
+find the reason for your performance issues, you may conclude that locking
+is the issue and therefore look into how to remove the locks ...</p>
+<p>DO NOT DO THAT! Removing locks would be <strong>wrong</strong> and it will cause you
+more problems!</p>
+<p>Locking is not the issue, it is a solution. Your issue is that you still
+have the session open, while you&#8217;ve already processed it and therefore no
+longer need it. So, what you need is to close the session for the
+current request after you no longer need it.</p>
+<p>Long story short - call <tt class="docutils literal"><span class="pre">session_write_close()</span></tt> once you no longer need
+anything to do with session variables.</p>

+<h3><a class="toc-backref" href="#id7">What is Session Data?</a><a class="headerlink" href="#what-is-session-data" title="Permalink to this headline">¶</a></h3>
+<p>Session data is simply an array associated with a particular session ID
+(cookie).</p>
+<p>If you&#8217;ve used sessions in PHP before, you should be familiar with PHP&#8217;s
+<a class="reference external" href="http://php.net/manual/en/reserved.variables.session.php">$_SESSION superglobal</a>
+(if not, please read the content on that link).</p>
+<p>CodeIgniter gives access to its session data through the same means, as it
+uses the session handlers&#8217; mechanism provided by PHP. Using session data is
+as simple as manipulating (read, set and unset values) the <tt class="docutils literal"><span class="pre">$_SESSION</span></tt>
+array.</p>
+<p>In addition, CodeIgniter also provides 2 special types of session data
+that are further explained below: flashdata and tempdata.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">In previous versions, regular session data in CodeIgniter was
+referred to as &#8216;userdata&#8217;. Have this in mind if that term is used
+elsewhere in the manual. Most of it is written to explain how

+<p>However, any other driver may be selected via the <tt class="docutils literal"><span class="pre">$config['sess_driver']</span></tt>
+line in your <strong>application/config/config.php</strong> file, if you chose to do so.
+Have it in mind though, every driver has different caveats, so be sure to
+get yourself familiar with them (below) before you make that choice.</p>
+<p>In addition, you may also create and use <a class="reference internal" href="#custom-drivers">Custom Drivers</a>, if the ones

+<p>The &#8216;files&#8217; driver uses your file system for storing session data.</p>
+<p>It can safely be said that it works exactly like PHP&#8217;s own default session
+implementation, but in case this is an important detail for you, have it
+mind that it is in fact not the same code and it has some limitations
+(and advantages).</p>
+<p>To be more specific, it doesn&#8217;t support PHP&#8217;s <a class="reference external" href="http://php.net/manual/en/session.configuration.php#ini.session.save-path">directory level and mode
+formats used in session.save_path</a>,
+and it has most of the options hard-coded for safety. Instead, only
+absolute paths are supported for <tt class="docutils literal"><span class="pre">$config['sess_save_path']</span></tt>.</p>
+<p>Another important thing that you should know, is to make sure that you
+don&#8217;t use a publicly-readable or shared directory for storing your session
+files. Make sure that <em>only you</em> have access to see the contents of your
+chosen <em>sess_save_path</em> directory. Otherwise, anybody who can do that, can
+also steal any of the current sessions (also known as &#8220;session fixation&#8221;
+attack).</p>
+<p>On UNIX-like operating systems, this is usually achieved by setting the
+0700 mode permissions on that directory via the <cite>chmod</cite> command, which
+allows only the directory&#8217;s owner to perform read and write operations on
+it. But be careful because the system user <em>running</em> the script is usually
+not your own, but something like &#8216;www-data&#8217; instead, so only setting those
+permissions will probable break your application.</p>

+<p>Some of you will probably opt to choose another session driver because
+file storage is usually slower. This is only half true.</p>
+<p>A very basic test will probably trick you into believing that an SQL
+database is faster, but in 99% of the cases, this is only true while you
+only have a few current sessions. As the sessions count and server loads
+increase - which is the time when it matters - the file system will
+consistently outperform almost all relational database setups.</p>
+<p>In addition, if performance is your only concern, you may want to look
+into using <a class="reference external" href="http://eddmann.com/posts/storing-php-sessions-file-caches-in-memory-using-tmpfs/">tmpfs</a>,

+<p>The &#8216;database&#8217; driver uses a relational database such as MySQL or
+PostgreSQL to store sessions. This is a popular choice among many users,
+because it allows the developer easy access to the session data within
+an application - it is just another table in your database.</p>
+<p>However, there are some conditions that must be met:</p>
+<blockquote>
+<div><ul class="simple">
+<li>Only your <strong>default</strong> database connection (or the one that you access
+as <tt class="docutils literal"><span class="pre">$this-&gt;db</span></tt> from your controllers) can be used.</li>
+<li>You must have the <a class="reference internal" href="../database/query_builder.html"><em>Query Builder</em></a>
+enabled.</li>
+<li>You can NOT use a persistent connection.</li>
+<li>You can NOT use a connection with the <em>cache_on</em> setting enabled.</li>
+</ul>
+</div></blockquote>
+<p>In order to use the &#8216;database&#8217; session driver, you must also create this
+table that we already mentioned and then set it as your
+<tt class="docutils literal"><span class="pre">$config['sess_save_path']</span></tt> value.
+For example, if you would like to use &#8216;ci_sessions&#8217; as your table name,
+you would do this:</p>

+<p>Redis is a storage engine typically used for caching and popular because

+<p>The downside is that it is not as ubiquitous as relational databases and

+<p>The &#8216;memcached&#8217; driver is very similar to the &#8216;redis&#8217; one in all of its

+<p>However, it is worth noting that the only guarantee given by Memcached
+is that setting value X to expire after Y seconds will result in it being

+<p>You may also create your own, custom session drivers. However, have it in
+mind that this is typically not an easy task, as it takes a lot of
+knowledge to do it properly.</p>
+<p>You need to know not only how sessions work in general, but also how they
+work specifically in PHP, how the underlying storage mechanism works, how
+to handle concurrency, avoid deadlocks (but NOT through lack of locks) and
+last but not least - how to handle the potential security issues, which
+is far from trivial.</p>
+<p>Long story short - if you don&#8217;t know how to do that already in raw PHP,
+you shouldn&#8217;t be trying to do it within CodeIgniter either. You&#8217;ve been
+warned.</p>
+<p>If you only want to add some extra functionality to your sessions, just
+extend the base Session class, which is a lot more easier. Read the
+<a class="reference internal" href="../general/creating_libraries.html"><em>Creating Libraries</em></a> article to
+learn how to do that.</p>
+<p>Now, to the point - there are three general rules that you must follow
+when creating a session driver for CodeIgniter:</p>
+<blockquote>
+<div><ul>
+<li><p class="first">Put your driver&#8217;s file under <strong>application/libraries/Session/drivers/</strong>
+and follow the naming conventions used by the Session class.</p>
+<p>For example, if you were to create a &#8216;dummy&#8217; driver, you would have
+a <tt class="docutils literal"><span class="pre">Session_dummy_driver</span></tt> class name, that is declared in
+<em>application/libraries/Session/drivers/Session_dummy_driver.php</em>.</p>
+</li>
+<li><p class="first">Extend the <tt class="docutils literal"><span class="pre">CI_Session_driver</span></tt> class.</p>
+<p>This is just a basic class with a few internal helper methods. It is
+also extendable like any other library, if you really need to do that,
+but we are not going to explain how ... if you&#8217;re familiar with how
+class extensions/overrides work in CI, then you already know how to do
+it. If not, well, you shouldn&#8217;t be doing it in the first place.</p>
+</li>
+<li><p class="first">Implement the <a class="reference external" href="http://php.net/sessionhandlerinterface">SessionHandlerInterface</a> interface.</p>
+<div class="admonition note">
+<p class="first admonition-title">Note</p>
+<p class="last">You may notice that <tt class="docutils literal"><span class="pre">SessionHandlerInterface</span></tt> is provided
+by PHP since version 5.4.0. CodeIgniter will automatically declare
+the same interface if you&#8217;re running an older PHP version.</p>
+</div>
+<p>The link will explain why and how.</p>
+</li>
+</ul>

+<p>So, based on our &#8216;dummy&#8217; driver example above, you&#8217;d end up with something

+<p>Before you can receive Trackbacks you must create a weblog. If you don&#8217;t
+have a blog yet there&#8217;s no point in continuing.</p>
+<p>Receiving Trackbacks is a little more complex than sending them, only
+because you will need a database table in which to store them, and you
+will need to validate the incoming trackback data. You are encouraged to
+implement a thorough validation process to guard against spam and
+duplicate data. You may also want to limit the number of Trackbacks you
+allow from a particular IP within a given span of time to further
+curtail spam. The process of receiving a Trackback is quite simple; the
+validation is what takes most of the effort.</p>

+<h3><a class="toc-backref" href="#id5">Your Ping URL</a><a class="headerlink" href="#your-ping-url" title="Permalink to this headline">¶</a></h3>
+<p>In order to accept Trackbacks you must display a Trackback URL next to
+each one of your weblog entries. This will be the URL that people will
+use to send you Trackbacks (we will refer to this as your &#8220;Ping URL&#8221;).</p>
+<p>Your Ping URL must point to a controller function where your Trackback
+receiving code is located, and the URL must contain the ID number for
+each particular entry, so that when the Trackback is received you&#8217;ll be
+able to associate it with a particular entry.</p>
+<p>For example, if your controller class is called Trackback, and the
+receiving function is called receive, your Ping URLs will look something
+like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">trackback</span><span class="o">/</span><span class="nx">receive</span><span class="o">/</span><span class="nx">entry_id</span>

+<p>The entry ID number is expected in the third segment of your URL. This
+is based on the URI example we gave earlier:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">http</span><span class="o">://</span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">trackback</span><span class="o">/</span><span class="nx">receive</span><span class="o">/</span><span class="nx">entry_id</span>
+</pre></div>
+</div>
+<p>Notice the entry_id is in the third URI segment, which you can retrieve
+using:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">uri</span><span class="o">-&gt;</span><span class="na">segment</span><span class="p">(</span><span class="mi">3</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>In our Trackback receiving code above, if the third segment is missing,
+we will issue an error. Without a valid entry ID, there&#8217;s no reason to
+continue.</p>
+<p>The $this-&gt;trackback-&gt;receive() function is simply a validation function
+that looks at the incoming data and makes sure it contains the four
+pieces of data that are required (url, title, excerpt, blog_name). It
+returns TRUE on success and FALSE on failure. If it fails you will issue
+an error message.</p>
+<p>The incoming Trackback data can be retrieved using this function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">trackback</span><span class="o">-&gt;</span><span class="na">data</span><span class="p">(</span><span class="s1">&#39;item&#39;</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>Where item represents one of these four pieces of info: url, title,
+excerpt, or blog_name</p>
+<p>If the Trackback data is successfully received, you will issue a success
+message using:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">trackback</span><span class="o">-&gt;</span><span class="na">send_success</span><span class="p">();</span>

+<blockquote>
+<div><ul class="simple">

+<li>Single line breaks are converted to &lt;br /&gt;, except those that appear within &lt;pre&gt; tags.</li>
+<li>Block level elements, like &lt;div&gt; tags, are not wrapped within paragraphs, but their contained text is if it contains paragraphs.</li>

+<h1>Unit Testing Class<a class="headerlink" href="#unit-testing-class" title="Permalink to this headline">¶</a></h1>
+<p>Unit testing is an approach to software development in which tests are
+written for each function in your application. If you are not familiar
+with the concept you might do a little googling on the subject.</p>
+<p>CodeIgniter&#8217;s Unit Test class is quite simple, consisting of an
+evaluation function and two result functions. It&#8217;s not intended to be a
+full-blown test suite but rather a simple mechanism to evaluate your
+code to determine if it is producing the correct data type and result.</p>

+<p>Like most other classes in CodeIgniter, the Unit Test class is
+initialized in your controller using the $this-&gt;load-&gt;library function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;unit_test&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Once loaded, the Unit Test object will be available using <tt class="docutils literal"><span class="pre">$this-&gt;unit</span></tt></p>
+</div>
+<div class="section" id="running-tests">
+<h3><a class="toc-backref" href="#id3">Running Tests</a><a class="headerlink" href="#running-tests" title="Permalink to this headline">¶</a></h3>
+<p>Running a test involves supplying a test and an expected result in the
+following way:</p>
+<blockquote>
+<div>$this-&gt;unit-&gt;run(&#8216;test&#8217;, &#8216;expected result&#8217;, &#8216;test name&#8217;, &#8216;notes&#8217;);</div></blockquote>
+<p>Where test is the result of the code you wish to test, expected result
+is the data type you expect, test name is an optional name you can give
+your test, and notes are optional notes. Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$test</span> <span class="o">=</span> <span class="mi">1</span> <span class="o">+</span> <span class="mi">1</span><span class="p">;</span>
+
+<span class="nv">$expected_result</span> <span class="o">=</span> <span class="mi">2</span><span class="p">;</span>
+
+<span class="nv">$test_name</span> <span class="o">=</span> <span class="s1">&#39;Adds one plus one&#39;</span><span class="p">;</span>
+
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">unit</span><span class="o">-&gt;</span><span class="na">run</span><span class="p">(</span><span class="nv">$test</span><span class="p">,</span> <span class="nv">$expected_result</span><span class="p">,</span> <span class="nv">$test_name</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The expected result you supply can either be a literal match, or a data
+type match. Here&#8217;s an example of a literal:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">unit</span><span class="o">-&gt;</span><span class="na">run</span><span class="p">(</span><span class="s1">&#39;Foo&#39;</span><span class="p">,</span> <span class="s1">&#39;Foo&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Here is an example of a data type match:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">unit</span><span class="o">-&gt;</span><span class="na">run</span><span class="p">(</span><span class="s1">&#39;Foo&#39;</span><span class="p">,</span> <span class="s1">&#39;is_string&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Notice the use of &#8220;is_string&#8221; in the second parameter? This tells the
+function to evaluate whether your test is producing a string as the
+result. Here is a list of allowed comparison types:</p>
+<ul class="simple">
+<li>is_object</li>
+<li>is_string</li>
+<li>is_bool</li>
+<li>is_true</li>
+<li>is_false</li>
+<li>is_int</li>
+<li>is_numeric</li>
+<li>is_float</li>
+<li>is_double</li>
+<li>is_array</li>
+<li>is_null</li>
+<li>is_resource</li>
+</ul>
+</div>
+<div class="section" id="generating-reports">
+<h3><a class="toc-backref" href="#id4">Generating Reports</a><a class="headerlink" href="#generating-reports" title="Permalink to this headline">¶</a></h3>
+<p>You can either display results after each test, or your can run several
+tests and generate a report at the end. To show a report directly simply
+echo or return the run function:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">unit</span><span class="o">-&gt;</span><span class="na">run</span><span class="p">(</span><span class="nv">$test</span><span class="p">,</span> <span class="nv">$expected_result</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>To run a full report of all tests, use this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">unit</span><span class="o">-&gt;</span><span class="na">report</span><span class="p">();</span>
+</pre></div>
+</div>
+<p>The report will be formatted in an HTML table for viewing. If you prefer
+the raw data you can retrieve an array using:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">unit</span><span class="o">-&gt;</span><span class="na">result</span><span class="p">();</span>
+</pre></div>
+</div>
+</div>
+<div class="section" id="strict-mode">
+<h3><a class="toc-backref" href="#id5">Strict Mode</a><a class="headerlink" href="#strict-mode" title="Permalink to this headline">¶</a></h3>
+<p>By default the unit test class evaluates literal matches loosely.
+Consider this example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">unit</span><span class="o">-&gt;</span><span class="na">run</span><span class="p">(</span><span class="mi">1</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The test is evaluating an integer, but the expected result is a boolean.
+PHP, however, due to it&#8217;s loose data-typing will evaluate the above code
+as TRUE using a normal equality test:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">if</span> <span class="p">(</span><span class="mi">1</span> <span class="o">==</span> <span class="k">TRUE</span><span class="p">)</span> <span class="k">echo</span> <span class="s1">&#39;This evaluates as true&#39;</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>If you prefer, you can put the unit test class in to strict mode, which
+will compare the data type as well as the value:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">if</span> <span class="p">(</span><span class="mi">1</span> <span class="o">===</span> <span class="k">TRUE</span><span class="p">)</span> <span class="k">echo</span> <span class="s1">&#39;This evaluates as FALSE&#39;</span><span class="p">;</span>
+</pre></div>

+number you wish to retrieve. Segments are numbered from left to right.
+For example, if your full URL is this:</p>

+<p>The optional second parameter defaults to NULL and allows you to set the return value
+of this method when the requested URI segment is missing.

+<p>This method lets you turn URI segments into an associative array of

+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">user</span><span class="o">/</span><span class="nx">search</span><span class="o">/</span><span class="nx">name</span><span class="o">/</span><span class="nx">joe</span><span class="o">/</span><span class="nx">location</span><span class="o">/</span><span class="nx">UK</span><span class="o">/</span><span class="nx">gender</span><span class="o">/</span><span class="nx">male</span>
+</pre></div>
+</div>
+<p>Using this method you can turn the URI into an associative array with
+this prototype:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="p">[</span><span class="k">array</span><span class="p">]</span>
+<span class="p">(</span>

+<span class="p">)</span>
+</pre></div>
+</div>
+<p>The first parameter lets you set an offset, which defaults to 3 since your
+URI will normally contain a controller/method pair in the first and second segments.
+Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$array</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">uri</span><span class="o">-&gt;</span><span class="na">uri_to_assoc</span><span class="p">(</span><span class="mi">3</span><span class="p">);</span>
+<span class="k">echo</span> <span class="nv">$array</span><span class="p">[</span><span class="s1">&#39;name&#39;</span><span class="p">];</span>
+</pre></div>
+</div>
+<p>The second parameter lets you set default key names, so that the array
+returned will always contain expected indexes, even if missing from the URI.
+Example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$default</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;name&#39;</span><span class="p">,</span> <span class="s1">&#39;gender&#39;</span><span class="p">,</span> <span class="s1">&#39;location&#39;</span><span class="p">,</span> <span class="s1">&#39;type&#39;</span><span class="p">,</span> <span class="s1">&#39;sort&#39;</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>If the URI does not contain a value in your default, an array index will
+be set to that name, with a value of NULL.</p>
+<p>Lastly, if a corresponding value is not found for a given key (if there
+is an odd number of URI segments) the value will be set to NULL.</p>

+<p>Quite simply it is a way for two computers to communicate over the
+internet using XML. One computer, which we will call the client, sends
+an XML-RPC <strong>request</strong> to another computer, which we will call the
+server. Once the server receives and processes the request it will send
+back a <strong>response</strong> to the client.</p>
+<p>For example, using the MetaWeblog API, an XML-RPC Client (usually a
+desktop publishing tool) will send a request to an XML-RPC Server
+running on your site. This request might be a new weblog entry being
+sent for publication, or it could be a request for an existing entry for
+editing. When the XML-RPC Server receives this request it will examine
+it to determine which class/method should be called to process the
+request. Once processed, the server will then send back a response
+message.</p>

+<p>An XML-RPC request is simply the data you are sending to the XML-RPC
+server. Each piece of data in a request is referred to as a request
+parameter. The above example has two parameters: The URL and title of
+your site. When the XML-RPC server receives your request, it will look
+for parameters it requires.</p>
+<p>Request parameters must be placed into an array for transportation, and
+each parameter can be one of seven data types (strings, numbers, dates,
+etc.). If your parameters are something other than strings you will have
+to include the data type in the request array.</p>
+<p>Here is an example of a simple array with three parameters:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$request</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;John&#39;</span><span class="p">,</span> <span class="s1">&#39;Doe&#39;</span><span class="p">,</span> <span class="s1">&#39;www.some-site.com&#39;</span><span class="p">);</span>

+</pre></div>
+</div>
+<p>If you use data types other than strings, or if you have several
+different data types, you will place each parameter into its own array,
+with the data type in the second position:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$request</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>

+<p>An XML-RPC Server acts as a traffic cop of sorts, waiting for incoming
+requests and redirecting them to the appropriate functions for
+processing.</p>
+<p>To create your own XML-RPC server involves initializing the XML-RPC
+Server class in your controller where you expect the incoming request to
+appear, then setting up an array with mapping instructions so that
+incoming requests can be sent to the appropriate class and method for
+processing.</p>
+<p>Here is an example to illustrate:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;xmlrpc&#39;</span><span class="p">);</span>

+<p>The above example contains an array specifying two method requests that
+the Server allows. The allowed methods are on the left side of the
+array. When either of those are received, they will be mapped to the
+class and method on the right.</p>
+<p>The &#8216;object&#8217; key is a special key that you pass an instantiated class
+object with, which is necessary when the method you are mapping to is
+not part of the CodeIgniter super object.</p>
+<p>In other words, if an XML-RPC Client sends a request for the new_post
+method, your server will load the My_blog class and call the new_entry
+function. If the request is for the update_post method, your server
+will load the My_blog class and call the <tt class="docutils literal"><span class="pre">update_entry()</span></tt> method.</p>
+<p>The function names in the above example are arbitrary. You&#8217;ll decide
+what they should be called on your server, or if you are using
+standardized APIs, like the Blogger or MetaWeblog API, you&#8217;ll use their
+function names.</p>
+<p>There are two additional configuration keys you may make use of when
+initializing the server class: debug can be set to TRUE in order to
+enable debugging, and xss_clean may be set to FALSE to prevent sending
+data through the Security library&#8217;s <tt class="docutils literal"><span class="pre">xss_clean()</span></tt> method.</p>

+<p>When the XML-RPC Server receives a request and loads the class/method
+for processing, it will pass an object to that method containing the
+data sent by the client.</p>
+<p>Using the above example, if the new_post method is requested, the
+server will expect a class to exist with this prototype:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">My_blog</span> <span class="k">extends</span> <span class="nx">CI_Controller</span> <span class="p">{</span>

+        <span class="p">{</span>
+
+        <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>The $request variable is an object compiled by the Server, which
+contains the data sent by the XML-RPC Client. Using this object you will
+have access to the <em>request parameters</em> enabling you to process the
+request. When you are done you will send a Response back to the Client.</p>
+<p>Below is a real-world example, using the Blogger API. One of the methods
+in the Blogger API is <tt class="docutils literal"><span class="pre">getUserInfo()</span></tt>. Using this method, an XML-RPC
+Client can send the Server a username and password, in return the Server
+sends back information about that particular user (nickname, user ID,
+email address, etc.). Here is how the processing function might look:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">My_blog</span> <span class="k">extends</span> <span class="nx">CI_Controller</span> <span class="p">{</span>

+<h3><a class="toc-backref" href="#id12">Formatting a Response</a><a class="headerlink" href="#formatting-a-response" title="Permalink to this headline">¶</a></h3>
+<p>Similar to <em>Requests</em>, <em>Responses</em> must be formatted as an array.
+However, unlike requests, a response is an array <strong>that contains a
+single item</strong>. This item can be an array with several additional arrays,
+but there can be only one primary array index. In other words, the basic
+prototype is this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$response</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;Response data&#39;</span><span class="p">,</span> <span class="s1">&#39;array&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Responses, however, usually contain multiple pieces of information. In
+order to accomplish this we must put the response into its own array so
+that the primary array continues to contain a single piece of data.
+Here&#8217;s an example showing how this might be accomplished:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$response</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>

+<ol class="arabic simple">
+<li>The index.php serves as the front controller, initializing the base
+resources needed to run CodeIgniter.</li>
+<li>The Router examines the HTTP request to determine what should be done
+with it.</li>
+<li>If a cache file exists, it is sent directly to the browser, bypassing
+the normal system execution.</li>
+<li>Security. Before the application controller is loaded, the HTTP
+request and any user submitted data is filtered for security.</li>
+<li>The Controller loads the model, core libraries, helpers, and any
+other resources needed to process the specific request.</li>
+<li>The finalized View is rendered then sent to the web browser to be
+seen. If caching is enabled, the view is cached first so that on
+subsequent requests it can be served.</li>

+<h2>CodeIgniter is an Application Framework<a class="headerlink" href="#codeigniter-is-an-application-framework" title="Permalink to this headline">¶</a></h2>
+<p>CodeIgniter is a toolkit for people who build web applications using
+PHP. Its goal is to enable you to develop projects much faster than you
+could if you were writing code from scratch, by providing a rich set of
+libraries for commonly needed tasks, as well as a simple interface and
+logical structure to access these libraries. CodeIgniter lets you
+creatively focus on your project by minimizing the amount of code needed
+for a given task.</p>

+<p>CodeIgniter is licensed under the MIT license so you can use it however

+<h2>CodeIgniter is Light Weight<a class="headerlink" href="#codeigniter-is-light-weight" title="Permalink to this headline">¶</a></h2>
+<p>Truly light weight. The core system requires only a few very small
+libraries. This is in stark contrast to many frameworks that require
+significantly more resources. Additional libraries are loaded
+dynamically upon request, based on your needs for a given process, so
+the base system is very lean and quite fast.</p>
+</div>
+<div class="section" id="codeigniter-is-fast">
+<h2>CodeIgniter is Fast<a class="headerlink" href="#codeigniter-is-fast" title="Permalink to this headline">¶</a></h2>
+<p>Really fast. We challenge you to find a framework that has better
+performance than CodeIgniter.</p>

+<h2>CodeIgniter Uses M-V-C<a class="headerlink" href="#codeigniter-uses-m-v-c" title="Permalink to this headline">¶</a></h2>
+<p>CodeIgniter uses the Model-View-Controller approach, which allows great
+separation between logic and presentation. This is particularly good for
+projects in which designers are working with your template files, as the
+code these files contain will be minimized. We describe MVC in more
+detail on its own page.</p>

+<div class="section" id="codeigniter-generates-clean-urls">
+<h2>CodeIgniter Generates Clean URLs<a class="headerlink" href="#codeigniter-generates-clean-urls" title="Permalink to this headline">¶</a></h2>
+<p>The URLs generated by CodeIgniter are clean and search-engine friendly.
+Rather than using the standard &#8220;query string&#8221; approach to URLs that is
+synonymous with dynamic systems, CodeIgniter uses a segment-based
+approach:</p>

+<h2>CodeIgniter Does Not Require a Template Engine<a class="headerlink" href="#codeigniter-does-not-require-a-template-engine" title="Permalink to this headline">¶</a></h2>
+<p>Although CodeIgniter <em>does</em> come with a simple template parser that can
+be optionally used, it does not force you to use one. Template engines
+simply can not match the performance of native PHP, and the syntax that
+must be learned to use a template engine is usually only marginally
+easier than learning the basics of PHP. Consider this block of PHP code:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">ul</span><span class="o">&gt;</span>
+<span class="o">&lt;?</span><span class="nx">php</span> <span class="k">foreach</span> <span class="p">(</span><span class="nv">$addressbook</span> <span class="k">as</span> <span class="nv">$name</span><span class="p">)</span><span class="o">:</span><span class="cp">?&gt;</span>
+        <span class="p">&lt;</span><span class="nt">li</span><span class="p">&gt;</span><span class="cp">&lt;?</span><span class="o">=</span><span class="nv">$name</span><span class="cp">?&gt;</span><span class="p">&lt;/</span><span class="nt">li</span><span class="p">&gt;</span>
+<span class="cp">&lt;?php</span> <span class="k">endforeach</span><span class="p">;</span> <span class="cp">?&gt;</span>
+<span class="p">&lt;/</span><span class="nt">ul</span><span class="p">&gt;</span>
+</pre></div>
+</div>
+<p>Contrast this with the pseudo-code used by a template engine:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">ul</span><span class="o">&gt;</span>
+<span class="p">{</span><span class="k">foreach</span> <span class="nx">from</span><span class="o">=</span><span class="nv">$addressbook</span> <span class="nx">item</span><span class="o">=</span><span class="s2">&quot;name&quot;</span><span class="p">}</span>
+        <span class="o">&lt;</span><span class="nx">li</span><span class="o">&gt;</span><span class="p">{</span><span class="nv">$name</span><span class="p">}</span><span class="o">&lt;/</span><span class="nx">li</span><span class="o">&gt;</span>
+<span class="p">{</span><span class="o">/</span><span class="k">foreach</span><span class="p">}</span>
+<span class="o">&lt;/</span><span class="nx">ul</span><span class="o">&gt;</span>
+</pre></div>
+</div>
+<p>Yes, the template engine example is a bit cleaner, but it comes at the
+price of performance, as the pseudo-code must be converted back into PHP
+to run. Since one of our goals is <em>maximum performance</em>, we opted to not
+require the use of a template engine.</p>

+<h1>CodeIgniter Features<a class="headerlink" href="#codeigniter-features" title="Permalink to this headline">¶</a></h1>
+<p>Features in and of themselves are a very poor way to judge an
+application since they tell you nothing about the user experience, or
+how intuitively or intelligently it is designed. Features don&#8217;t reveal
+anything about the quality of the code, or the performance, or the
+attention to detail, or security practices. The only way to really judge
+an app is to try it and get to know the code.

+<p>Any software application requires some effort to learn. We&#8217;ve done our
+best to minimize the learning curve while making the process as
+enjoyable as possible.</p>
+<p>The first step is to <a class="reference internal" href="../installation/index.html"><em>install</em></a>
+CodeIgniter, then read all the topics in the <strong>Introduction</strong> section of
+the Table of Contents.</p>
+<p>Next, read each of the <strong>General Topics</strong> pages in order. Each topic
+builds on the previous one, and includes code examples that you are
+encouraged to try.</p>
+<p>Once you understand the basics you&#8217;ll be ready to explore the <strong>Class
+Reference</strong> and <strong>Helper Reference</strong> pages to learn to utilize the
+native libraries and helper files.</p>
+<p>Feel free to take advantage of our <a class="reference external" href="http://forum.codeigniter.com/">Community
+Forums</a> if you have questions or
+problems, and our <a class="reference external" href="https://github.com/bcit-ci/CodeIgniter/wiki">Wiki</a> to see code
+examples posted by other users.</p>

+<h1>Design and Architectural Goals<a class="headerlink" href="#design-and-architectural-goals" title="Permalink to this headline">¶</a></h1>
+<p>Our goal for CodeIgniter is maximum performance, capability, and
+flexibility in the smallest, lightest possible package.</p>
+<p>To meet this goal we are committed to benchmarking, re-factoring, and
+simplifying at every step of the development process, rejecting anything
+that doesn&#8217;t further the stated objective.</p>
+<p>From a technical and architectural standpoint, CodeIgniter was created
+with the following objectives:</p>
+<ul class="simple">
+<li><strong>Dynamic Instantiation.</strong> In CodeIgniter, components are loaded and
+routines executed only when requested, rather than globally. No
+assumptions are made by the system regarding what may be needed
+beyond the minimal core resources, so the system is very light-weight
+by default. The events, as triggered by the HTTP request, and the
+controllers and views you design will determine what is invoked.</li>
+<li><strong>Loose Coupling.</strong> Coupling is the degree to which components of a
+system rely on each other. The less components depend on each other
+the more reusable and flexible the system becomes. Our goal was a
+very loosely coupled system.</li>
+<li><strong>Component Singularity.</strong> Singularity is the degree to which
+components have a narrowly focused purpose. In CodeIgniter, each
+class and its functions are highly autonomous in order to allow
+maximum usefulness.</li>
+</ul>
+<p>CodeIgniter is a dynamically instantiated, loosely coupled system with
+high component singularity. It strives for simplicity, flexibility, and
+high performance in a small footprint package.</p>

+<h1>Model-View-Controller<a class="headerlink" href="#model-view-controller" title="Permalink to this headline">¶</a></h1>
+<p>CodeIgniter is based on the Model-View-Controller development pattern.
+MVC is a software approach that separates application logic from
+presentation. In practice, it permits your web pages to contain minimal
+scripting since the presentation is separate from the PHP scripting.</p>
+<ul class="simple">
+<li>The <strong>Model</strong> represents your data structures. Typically your model
+classes will contain functions that help you retrieve, insert, and
+update information in your database.</li>
+<li>The <strong>View</strong> is the information that is being presented to a user. A
+View will normally be a web page, but in CodeIgniter, a view can also
+be a page fragment like a header or footer. It can also be an RSS
+page, or any other type of &#8220;page&#8221;.</li>
+<li>The <strong>Controller</strong> serves as an <em>intermediary</em> between the Model, the
+View, and any other resources needed to process the HTTP request and
+generate a web page.</li>
+</ul>
+<p>CodeIgniter has a fairly loose approach to MVC since Models are not
+required. If you don&#8217;t need the added separation, or find that
+maintaining models requires more complexity than you want, you can
+ignore them and build your application minimally using Controllers and
+Views. CodeIgniter also enables you to incorporate your own existing
+scripts, or even develop core libraries for the system, enabling you to
+work in a way that makes the most sense to you.</p>

+<p>This tutorial did not cover all of the things you might expect of a
+full-fledged content management system, but it introduced you to the
+more important topics of routing, writing controllers, and models. We
+hope this tutorial gave you an insight into some of CodeIgniter&#8217;s basic
+design patterns, which you can expand upon.</p>
+<p>Now that you&#8217;ve completed this tutorial, we recommend you check out the
+rest of the documentation. CodeIgniter is often praised because of its
+comprehensive documentation. Use this to your advantage and read the
+&#8220;Introduction&#8221; and &#8220;General Topics&#8221; sections thoroughly. You should read
+the class and helper references when needed.</p>
+<p>Every intermediate PHP programmer should be able to get the hang of
+CodeIgniter within a few days.</p>
+<p>If you still have questions about the framework or your own CodeIgniter
+code, you can:</p>

+<p>There are only two things here that probably look unfamiliar to you: the
+<tt class="docutils literal"><span class="pre">form_open()</span></tt> function and the <tt class="docutils literal"><span class="pre">validation_errors()</span></tt> function.</p>
+<p>The first function is provided by the <a class="reference internal" href="../helpers/form_helper.html"><em>form
+helper</em></a> and renders the form element and
+adds extra functionality, like adding a hidden <a class="reference internal" href="../libraries/security.html"><em>CSRF prevention
+field</em></a>. The latter is used to report
+errors related to form validation.</p>
+<p>Go back to your news controller. You&#8217;re going to do two things here,
+check whether the form was submitted and whether the submitted data
+passed the validation rules. You&#8217;ll use the <a class="reference internal" href="../libraries/form_validation.html"><em>form
+validation</em></a> library to do this.</p>

+</pre></div>
+</div>
+<p>The code above adds a lot of functionality. The first few lines load the
+form helper and the form validation library. After that, rules for the
+form validation are set. The <tt class="docutils literal"><span class="pre">set_rules()</span></tt> method takes three arguments;
+the name of the input field, the name to be used in error messages, and
+the rule. In this case the title and text fields are required.</p>
+<p>CodeIgniter has a powerful form validation library as demonstrated
+above. You can read <a class="reference internal" href="../libraries/form_validation.html"><em>more about this library
+here</em></a>.</p>
+<p>Continuing down, you can see a condition that checks whether the form
+validation ran successfully. If it did not, the form is displayed, if it
+was submitted <strong>and</strong> passed all the rules, the model is called. After
+this, a view is loaded to display a success message. Create a view at
+<em>application/views/news/success.php</em> and write a success message.</p>
+</div>
+<div class="section" id="model">
+<h2>Model<a class="headerlink" href="#model" title="Permalink to this headline">¶</a></h2>
+<p>The only thing that remains is writing a method that writes the data to
+the database. You&#8217;ll use the Query Builder class to insert the
+information and use the input library to get the posted data. Open up
+the model created earlier and add the following:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">public</span> <span class="k">function</span> <span class="nf">set_news</span><span class="p">()</span>

+        <span class="s1">&#39;slug&#39;</span> <span class="o">=&gt;</span> <span class="nv">$slug</span><span class="p">,</span>
+        <span class="s1">&#39;text&#39;</span> <span class="o">=&gt;</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">input</span><span class="o">-&gt;</span><span class="na">post</span><span class="p">(</span><span class="s1">&#39;text&#39;</span><span class="p">)</span>
+    <span class="p">);</span>
+
+    <span class="k">return</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">db</span><span class="o">-&gt;</span><span class="na">insert</span><span class="p">(</span><span class="s1">&#39;news&#39;</span><span class="p">,</span> <span class="nv">$data</span><span class="p">);</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>This new method takes care of inserting the news item into the database.
+The third line contains a new function, url_title(). This function -
+provided by the <a class="reference internal" href="../helpers/url_helper.html"><em>URL helper</em></a> - strips down
+the string you pass it, replacing all spaces by dashes (-) and makes
+sure everything is in lowercase characters. This leaves you with a nice
+slug, perfect for creating URIs.</p>
+<p>Let&#8217;s continue with preparing the record that is going to be inserted
+later, inside the <tt class="docutils literal"><span class="pre">$data</span></tt> array. Each element corresponds with a column in
+the database table created earlier. You might notice a new method here,
+namely the <tt class="docutils literal"><span class="pre">post()</span></tt> method from the <a class="reference internal" href="../libraries/input.html"><em>input
+library</em></a>. This method makes sure the data is
+sanitized, protecting you from nasty attacks from others. The input
+library is loaded by default. At last, you insert our <tt class="docutils literal"><span class="pre">$data</span></tt> array into
+our database.</p>
+</div>
+<div class="section" id="routing">
+<h2>Routing<a class="headerlink" href="#routing" title="Permalink to this headline">¶</a></h2>
+<p>Before you can start adding news items into your CodeIgniter application
+you have to add an extra rule to <em>config/routes.php</em> file. Make sure your
+file contains the following. This makes sure CodeIgniter sees &#8216;create&#8217;
+as a method instead of a news item&#8217;s slug.</p>

+<h1>Tutorial<a class="headerlink" href="#tutorial" title="Permalink to this headline">¶</a></h1>
+<p>This tutorial is intended to introduce you to the CodeIgniter framework
+and the basic principles of MVC architecture. It will show you how a
+basic CodeIgniter application is constructed in step-by-step fashion.</p>
+<p>In this tutorial, you will be creating a <strong>basic news application</strong>. You
+will begin by writing the code that can load static pages. Next, you
+will create a news section that reads news items from a database.
+Finally, you&#8217;ll add a form to create news items in the database.</p>
+<p>This tutorial will primarily focus on:</p>
+<ul class="simple">
+<li>Model-View-Controller basics</li>
+<li>Routing basics</li>
+<li>Form validation</li>
+<li>Performing basic database queries using &#8220;Query Builder&#8221;</li>
+</ul>
+<p>The entire tutorial is split up over several pages, each explaining a
+small part of the functionality of the CodeIgniter framework. You&#8217;ll go
+through the following pages:</p>
+<ul class="simple">
+<li>Introduction, this page, which gives you an overview of what to
+expect.</li>
+<li><a class="reference internal" href="static_pages.html"><em>Static pages</em></a>, which will teach you the basics
+of controllers, views and routing.</li>
+<li><a class="reference internal" href="news_section.html"><em>News section</em></a>, where you&#8217;ll start using models
+and will be doing some basic database operations.</li>
+<li><a class="reference internal" href="create_news_items.html"><em>Create news items</em></a>, which will introduce
+more advanced database operations and form validation.</li>
+<li><a class="reference internal" href="conclusion.html"><em>Conclusion</em></a>, which will give you some pointers on
+further reading and other resources.</li>
+</ul>
+<p>Enjoy your exploration of the CodeIgniter framework.</p>

+<p>In the last section, we went over some basic concepts of the framework
+by writing a class that includes static pages. We cleaned up the URI by
+adding custom routing rules. Now it&#8217;s time to introduce dynamic content
+and start using a database.</p>

+<p>Instead of writing database operations right in the controller, queries
+should be placed in a model, so they can easily be reused later. Models
+are the place where you retrieve, insert, and update information in your
+database or other data stores. They represent your data.</p>
+<p>Open up the <em>application/models/</em> directory and create a new file called
+<em>News_model.php</em> and add the following code. Make sure you&#8217;ve configured
+your database properly as described <a class="reference internal" href="../database/configuration.html"><em>here</em></a>.</p>

+<p>This code looks similar to the controller code that was used earlier. It

+library. This will make the database class available through the
+<tt class="docutils literal"><span class="pre">$this-&gt;db</span></tt> object.</p>
+<p>Before querying the database, a database schema has to be created.
+Connect to your database and run the SQL command below (MySQL).

+</div>
+<p>Now that the database and a model have been set up, you&#8217;ll need a method
+to get all of our posts from our database. To do this, the database
+abstraction layer that is included with CodeIgniter —
+<a class="reference internal" href="../database/query_builder.html"><em>Query Builder</em></a> — is used. This makes it
+possible to write your &#8216;queries&#8217; once and make them work on <a class="reference internal" href="../general/requirements.html"><em>all
+supported database systems</em></a>. Add the
+following code to your model.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">public</span> <span class="k">function</span> <span class="nf">get_news</span><span class="p">(</span><span class="nv">$slug</span> <span class="o">=</span> <span class="k">FALSE</span><span class="p">)</span>

+<span class="p">}</span>
+</pre></div>
+</div>
+<p>With this code you can perform two different queries. You can get all
+news records, or get a news item by its <a class="reference external" href="#">slug</a>. You might have
+noticed that the <tt class="docutils literal"><span class="pre">$slug</span></tt> variable wasn&#8217;t sanitized before running the
+query; <a class="reference internal" href="../database/query_builder.html"><em>Query Builder</em></a> does this for you.</p>
+</div>
+<div class="section" id="display-the-news">
+<h2>Display the news<a class="headerlink" href="#display-the-news" title="Permalink to this headline">¶</a></h2>
+<p>Now that the queries are written, the model should be tied to the views
+that are going to display the news items to the user. This could be done
+in our <tt class="docutils literal"><span class="pre">Pages</span></tt> controller created earlier, but for the sake of clarity,
+a new <tt class="docutils literal"><span class="pre">News</span></tt> controller is defined. Create the new controller at

+</pre></div>
+</div>
+<p>Looking at the code, you may see some similarity with the files we
+created earlier. First, the <tt class="docutils literal"><span class="pre">__construct()</span></tt> method: it calls the
+constructor of its parent class (<tt class="docutils literal"><span class="pre">CI_Controller</span></tt>) and loads the model,
+so it can be used in all other methods in this controller.
+It also loads a collection of <a class="reference internal" href="../helpers/url_helper.html"><em>URL Helper</em></a>
+functions, because we&#8217;ll use one of them in a view later.</p>
+<p>Next, there are two methods to view all news items and one for a specific
+news item. You can see that the <tt class="docutils literal"><span class="pre">$slug</span></tt> variable is passed to the model&#8217;s
+method in the second method. The model is using this slug to identify the
+news item to be returned.</p>
+<p>Now the data is retrieved by the controller through our model, but
+nothing is displayed yet. The next thing to do is passing this data to
+the views.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">public</span> <span class="k">function</span> <span class="nf">index</span><span class="p">()</span>
+<span class="p">{</span>

+        <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">view</span><span class="p">(</span><span class="s1">&#39;templates/header&#39;</span><span class="p">,</span> <span class="nv">$data</span><span class="p">);</span>
+        <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">view</span><span class="p">(</span><span class="s1">&#39;news/index&#39;</span><span class="p">,</span> <span class="nv">$data</span><span class="p">);</span>

+<span class="p">}</span>
+</pre></div>
+</div>
+<p>The code above gets all news records from the model and assigns it to a
+variable. The value for the title is also assigned to the <tt class="docutils literal"><span class="pre">$data['title']</span></tt>
+element and all data is passed to the views. You now need to create a
+view to render the news items. Create <em>application/views/news/index.php</em>
+and add the next piece of code.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">h2</span><span class="o">&gt;&lt;?</span><span class="nx">php</span> <span class="k">echo</span> <span class="nv">$title</span><span class="p">;</span> <span class="cp">?&gt;</span><span class="p">&lt;/</span><span class="nt">h2</span><span class="p">&gt;</span>

+</pre></div>
+</div>
+<p>Here, each news item is looped and displayed to the user. You can see we
+wrote our template in PHP mixed with HTML. If you prefer to use a template
+language, you can use CodeIgniter&#8217;s <a class="reference internal" href="../libraries/parser.html"><em>Template
+Parser</em></a> class or a third party parser.</p>
+<p>The news overview page is now done, but a page to display individual
+news items is still absent. The model created earlier is made in such
+way that it can easily be used for this functionality. You only need to
+add some code to the controller and create a new view. Go back to the
+<tt class="docutils literal"><span class="pre">News</span></tt> controller and update <tt class="docutils literal"><span class="pre">view()</span></tt> with the following:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">public</span> <span class="k">function</span> <span class="nf">view</span><span class="p">(</span><span class="nv">$slug</span> <span class="o">=</span> <span class="k">NULL</span><span class="p">)</span>

+<h1>Static pages<a class="headerlink" href="#static-pages" title="Permalink to this headline">¶</a></h1>
+<p><strong>Note:</strong> This tutorial assumes you&#8217;ve downloaded CodeIgniter and
+<a class="reference internal" href="../installation/index.html"><em>installed the framework</em></a> in your
+development environment.</p>
+<p>The first thing you&#8217;re going to do is set up a <strong>controller</strong> to handle
+static pages. A controller is simply a class that helps delegate work.
+It is the glue of your web application.</p>
+<p>For example, when a call is made to:</p>
+<blockquote>
+<div><a class="reference external" href="http://example.com/news/latest/10">http://example.com/news/latest/10</a></div></blockquote>
+<p>We might imagine that there is a controller named &#8220;news&#8221;. The method
+being called on news would be &#8220;latest&#8221;. The news method&#8217;s job could be to
+grab 10 news items, and render them on the page. Very often in MVC,
+you&#8217;ll see URL patterns that match:</p>
+<blockquote>
+<div><a class="reference external" href="http://example.com/[controller-class]/[controller-method]/[arguments">http://example.com/[controller-class]/[controller-method]/[arguments</a>]</div></blockquote>
+<p>As URL schemes become more complex, this may change. But for now, this
+is all we will need to know.</p>
+<p>Create a file at <em>application/controllers/Pages.php</em> with the following
+code.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span>
+<span class="k">class</span> <span class="nc">Pages</span> <span class="k">extends</span> <span class="nx">CI_Controller</span> <span class="p">{</span>
+
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">view</span><span class="p">(</span><span class="nv">$page</span> <span class="o">=</span> <span class="s1">&#39;home&#39;</span><span class="p">)</span>
+        <span class="p">{</span>
+        <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>You have created a class named <tt class="docutils literal"><span class="pre">Pages</span></tt>, with a view method that accepts
+one argument named <tt class="docutils literal"><span class="pre">$page</span></tt>. The <tt class="docutils literal"><span class="pre">Pages</span></tt> class is extending the
+<tt class="docutils literal"><span class="pre">CI_Controller</span></tt> class. This means that the new pages class can access the
+methods and variables defined in the <tt class="docutils literal"><span class="pre">CI_Controller</span></tt> class
+(<em>system/core/Controller.php</em>).</p>
+<p>The <strong>controller is what will become the center of every request</strong> to
+your web application. In very technical CodeIgniter discussions, it may
+be referred to as the <em>super object</em>. Like any php class, you refer to
+it within your controllers as <tt class="docutils literal"><span class="pre">$this</span></tt>. Referring to <tt class="docutils literal"><span class="pre">$this</span></tt> is how
+you will load libraries, views, and generally command the framework.</p>
+<p>Now you&#8217;ve created your first method, it&#8217;s time to make some basic page
+templates. We will be creating two &#8220;views&#8221; (page templates) that act as
+our page footer and header.</p>
+<p>Create the header at <em>application/views/templates/header.php</em> and add
+the following code:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">html</span><span class="o">&gt;</span>
+        <span class="o">&lt;</span><span class="nx">head</span><span class="o">&gt;</span>
+                <span class="o">&lt;</span><span class="nx">title</span><span class="o">&gt;</span><span class="nx">CodeIgniter</span> <span class="nx">Tutorial</span><span class="o">&lt;/</span><span class="nx">title</span><span class="o">&gt;</span>
+        <span class="o">&lt;/</span><span class="nx">head</span><span class="o">&gt;</span>
+        <span class="o">&lt;</span><span class="nx">body</span><span class="o">&gt;</span>
+
+                <span class="o">&lt;</span><span class="nx">h1</span><span class="o">&gt;&lt;?</span><span class="nx">php</span> <span class="k">echo</span> <span class="nv">$title</span><span class="p">;</span> <span class="cp">?&gt;</span><span class="p">&lt;/</span><span class="nt">h1</span><span class="p">&gt;</span>
+</pre></div>
+</div>
+<p>The header contains the basic HTML code that you&#8217;ll want to display
+before loading the main view, together with a heading. It will also
+output the <tt class="docutils literal"><span class="pre">$title</span></tt> variable, which we&#8217;ll define later in the controller.
+Now, create a footer at <em>application/views/templates/footer.php</em> that
+includes the following code:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span>                <span class="o">&lt;</span><span class="nx">em</span><span class="o">&gt;&amp;</span><span class="nb">copy</span><span class="p">;</span> <span class="mi">2015</span><span class="o">&lt;/</span><span class="nx">em</span><span class="o">&gt;</span>
+        <span class="o">&lt;/</span><span class="nx">body</span><span class="o">&gt;</span>
+<span class="o">&lt;/</span><span class="nx">html</span><span class="o">&gt;</span>
+</pre></div>
+</div>
+<div class="section" id="adding-logic-to-the-controller">
+<h2>Adding logic to the controller<a class="headerlink" href="#adding-logic-to-the-controller" title="Permalink to this headline">¶</a></h2>
+<p>Earlier you set up a controller with a <tt class="docutils literal"><span class="pre">view()</span></tt> method. The method
+accepts one parameter, which is the name of the page to be loaded. The
+static page templates will be located in the <em>application/views/pages/</em>
+directory.</p>
+<p>In that directory, create two files named <em>home.php</em> and <em>about.php</em>.
+Within those files, type some text − anything you&#8217;d like − and save them.
+If you like to be particularly un-original, try &#8220;Hello World!&#8221;.</p>
+<p>In order to load those pages, you&#8217;ll have to check whether the requested
+page actually exists:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">public</span> <span class="k">function</span> <span class="nf">view</span><span class="p">(</span><span class="nv">$page</span> <span class="o">=</span> <span class="s1">&#39;home&#39;</span><span class="p">)</span>

+</div>
+<p>Now, when the page does exist, it is loaded, including the header and
+footer, and displayed to the user. If the page doesn&#8217;t exist, a &#8220;404
+Page not found&#8221; error is shown.</p>
+<p>The first line in this method checks whether the page actually exists.
+PHP&#8217;s native <tt class="docutils literal"><span class="pre">file_exists()</span></tt> function is used to check whether the file
+is where it&#8217;s expected to be. <tt class="docutils literal"><span class="pre">show_404()</span></tt> is a built-in CodeIgniter
+function that renders the default error page.</p>
+<p>In the header template, the <tt class="docutils literal"><span class="pre">$title</span></tt> variable was used to customize the
+page title. The value of title is defined in this method, but instead of
+assigning the value to a variable, it is assigned to the title element
+in the <tt class="docutils literal"><span class="pre">$data</span></tt> array.</p>
+<p>The last thing that has to be done is loading the views in the order
+they should be displayed. The second parameter in the <tt class="docutils literal"><span class="pre">view()</span></tt> method is
+used to pass values to the view. Each value in the <tt class="docutils literal"><span class="pre">$data</span></tt> array is
+assigned to a variable with the name of its key. So the value of
+<tt class="docutils literal"><span class="pre">$data['title']</span></tt> in the controller is equivalent to <tt class="docutils literal"><span class="pre">$title</span></tt> in the
+view.</p>
+</div>
+<div class="section" id="routing">
+<h2>Routing<a class="headerlink" href="#routing" title="Permalink to this headline">¶</a></h2>
+<p>The controller is now functioning! Point your browser to
+<tt class="docutils literal"><span class="pre">[your-site-url]index.php/pages/view</span></tt> to see your page. When you visit
+<tt class="docutils literal"><span class="pre">index.php/pages/view/about</span></tt> you&#8217;ll see the about page, again including
+the header and footer.</p>
+<p>Using custom routing rules, you have the power to map any URI to any
+controller and method, and break free from the normal convention:
+<tt class="docutils literal"><span class="pre">http://example.com/[controller-class]/[controller-method]/[arguments]</span></tt></p>
+<p>Let&#8217;s do that. Open the routing file located at
+<em>application/config/routes.php</em> and add the following two lines.
+Remove all other code that sets any element in the <tt class="docutils literal"><span class="pre">$route</span></tt> array.</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$route</span><span class="p">[</span><span class="s1">&#39;default_controller&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;pages/view&#39;</span><span class="p">;</span>
+<span class="nv">$route</span><span class="p">[</span><span class="s1">&#39;(:any)&#39;</span><span class="p">]</span> <span class="o">=</span> <span class="s1">&#39;pages/view/$1&#39;</span><span class="p">;</span>
+</pre></div>
+</div>
+<p>CodeIgniter reads its routing rules from top to bottom and routes the
+request to the first matching rule. Each rule is a regular expression
+(left-side) mapped to a controller and method name separated by slashes
+(right-side). When a request comes in, CodeIgniter looks for the first
+match, and calls the appropriate controller and method, possibly with
+arguments.</p>
+<p>More information about routing can be found in the URI Routing
+<a class="reference internal" href="../general/routing.html"><em>documentation</em></a>.</p>
+<p>Here, the second rule in the <tt class="docutils literal"><span class="pre">$routes</span></tt> array matches <strong>any</strong> request
+using the wildcard string <tt class="docutils literal"><span class="pre">(:any)</span></tt>. and passes the parameter to the
+<tt class="docutils literal"><span class="pre">view()</span></tt> method of the <tt class="docutils literal"><span class="pre">Pages</span></tt> class.</p>
+<p>Now visit <tt class="docutils literal"><span class="pre">index.php/about</span></tt>. Did it get routed correctly to the <tt class="docutils literal"><span class="pre">view()</span></tt>
+method in the pages controller? Awesome!</p>

-CodeIgniter User Guide
-######################
-
-******************
-Setup Instructions
-******************
-
-The CodeIgniter user guide uses Sphinx to manage the documentation and
-output it to various formats.  Pages are written in human-readable
-`ReStructured Text <http://sphinx.pocoo.org/rest.html>`_ format.
-
-Prerequisites
-=============
-
-Sphinx requires Python, which is already installed if you are running OS X.
-You can confirm in a Terminal window by executing the ``python`` command
-without any parameters.  It should load up and tell you which version you have
-installed.  If you're not on 2.7+, go ahead and install 2.7.2 from
-http://python.org/download/releases/2.7.2/
-
-Installation
-============
-
-1. Install `easy_install <http://peak.telecommunity.com/DevCenter/EasyInstall#installing-easy-install>`_
-2. ``easy_install "sphinx==1.2.3"``
-3. ``easy_install "sphinxcontrib-phpdomain==0.1.3.post1"``
-4. Install the CI Lexer which allows PHP, HTML, CSS, and JavaScript syntax highlighting in code examples (see *cilexer/README*)
-5. ``cd user_guide_src``
-6. ``make html``
-
-Editing and Creating Documentation
-==================================
-
-All of the source files exist under *source/* and is where you will add new
-documentation or modify existing documentation.  Just as with code changes,
-we recommend working from feature branches and making pull requests to
-the *develop* branch of this repo.
-
-So where's the HTML?
-====================
-
-Obviously, the HTML documentation is what we care most about, as it is the
-primary documentation that our users encounter.  Since revisions to the built
-files are not of value, they are not under source control.  This also allows
-you to regenerate as necessary if you want to "preview" your work.  Generating
-the HTML is very simple.  From the root directory of your user guide repo
-fork issue the command you used at the end of the installation instructions::
-
-	make html
-
-You will see it do a whiz-bang compilation, at which point the fully rendered
-user guide and images will be in *build/html/*.  After the HTML has been built,
-each successive build will only rebuild files that have changed, saving
-considerable time.  If for any reason you want to "reset" your build files,
-simply delete the *build* folder's contents and rebuild.
-
-***************
-Style Guideline
-***************
-
-Please refer to source/documentation/index.rst for general guidelines for
-using Sphinx to document CodeIgniter.

-To install the CodeIgniter Lexer to Pygments, run:
-
-	sudo python setup.py install
-
-Confirm with
-
-	pygmentize -L
-	
-
-You should see in the lexer output:
-
-* ci, codeigniter:
-    CodeIgniter (filenames *.html, *.css, *.php, *.xml, *.static)
-
-You will need to run setup.py and install the cilexer package anytime after cilexer/cilexer.py is updated
-
-NOTE: Depending on how you installed Sphinx and Pygments,
-you may be installing to the wrong version. 
-If you need to install to a different version of python
-specify its path when using setup.py, e.g.:
-
-	sudo /usr/bin/python2.5 setup.py install

-
-Version 2.0.3
-=============
-
-Release Date: August 20, 2011
-
--  Security
-
-   -  An improvement was made to the MySQL and MySQLi drivers to prevent
-      exposing a potential vector for SQL injection on sites using
-      multi-byte character sets in the database client connection.
-      An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
-      *mysql_set_charset()* creates a situation where using multi-byte
-      character sets on these environments may potentially expose a SQL
-      injection attack vector. Latin-1, UTF-8, and other "low ASCII"
-      character sets are unaffected on all environments.
-
-      If you are running or considering running a multi-byte character
-      set for your database connection, please pay close attention to
-      the server environment you are deploying on to ensure you are not
-      vulnerable.
-
--  General Changes
-

-      Variables.
-   -  Removed internal usage of the EXT constant.
-   -  Visual updates to the welcome_message view file and default error
-      templates. Thanks to `danijelb <https://bitbucket.org/danijelb>`_
-      for the pull request.
-   -  Added insert_batch() function to the PostgreSQL database driver.
-      Thanks to epallerols for the patch.
-   -  Added "application/x-csv" to mimes.php.
-   -  Fixed a bug where :doc:`Email library <libraries/email>`
-      attachments with a "." in the name would using invalid MIME-types.
-
--  Helpers
-
-   -  Added an optional third parameter to heading() which allows adding
-      html attributes to the rendered heading tag.
-   -  form_open() now only adds a hidden (Cross-site Reference Forgery)
-      protection field when the form's action is internal and is set to
-      the post method. (Reactor #165)
-   -  Re-worked plural() and singular() functions in the :doc:`Inflector
-      helper <helpers/inflector_helper>` to support considerably
-      more words.
-
--  Libraries
-
-   -  Altered Session to use a longer match against the user_agent
-      string. See upgrade notes if using database sessions.
-   -  Added $this->db->set_dbprefix() to the :doc:`Database
-      Driver <database/queries>`.
-   -  Changed $this->cart->insert() in the :doc:`Cart
-      Library <libraries/cart>` to return the Row ID if a single
-      item was inserted successfully.
-   -  Added $this->load->get_var() to the :doc:`Loader
-      library <libraries/loader>` to retrieve global vars set with
-      $this->load->view() and $this->load->vars().
-   -  Changed $this->db->having() to insert quotes using escape() rather
-      than escape_str().

--  Added ENVIRONMENT to reserved constants. (Reactor #196)
--  Changed server check to ensure SCRIPT_NAME is defined. (Reactor #57)
--  Removed APPPATH.'third_party' from the packages autoloader to negate
-   needless file stats if no packages exist or if the developer does not
-   load any other packages by default.
--  Fixed a bug (Reactor #231) where Sessions Library database table
-   example SQL did not contain an index on last_activity. See :doc:`Upgrade

-
-Version 2.0.0
-=============
-
-Release Date: January 28, 2011
-Hg Tag: v2.0.0

-   -  Scaffolding, having been deprecated for a number of versions, has
-      been removed.
-   -  Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
-      has been converted to a Helper and
-      :doc:`documented <./helpers/captcha_helper>`. The JavaScript
-      calendar plugin was removed due to the ready availability of great
-      JavaScript calendars, particularly with jQuery.
-   -  Added new special Library type:
-      :doc:`Drivers <./general/drivers>`.
-   -  Added full query-string support. See the config file for details.
-   -  Moved the application folder outside of the system folder.
-   -  Moved system/cache and system/logs directories to the application
-      directory.
-   -  Added routing overrides to the main index.php file, enabling the
-      normal routing to be overridden on a per "index" file basis.
-   -  Added the ability to set config values (or override config values)
-      directly from data set in the main index.php file. This allows a
-      single application to be used with multiple front controllers,
-      each having its own config values.
-   -  Added $config['directory_trigger'] to the config file so that a
-      controller sub-directory can be specified when running _GET
-      strings instead of URI segments.
-   -  Added ability to set "Package" paths - specific paths where the
-      Loader and Config classes should try to look first for a requested
-      file. This allows distribution of sub-applications with their own
-      libraries, models, config files, etc. in a single "package"
-      directory. See the :doc:`Loader class <libraries/loader>`
-      documentation for more details.
-   -  In-development code is now hosted at BitBucket .
-   -  Removed the deprecated Validation Class.
-   -  Added CI\_ Prefix to all core classes.
-   -  Package paths can now be set in application/config/autoload.php.
-   -  :doc:`Upload library <libraries/file_uploading>` file_name can
-      now be set without an extension, the extension will be taken from
-      the uploaded file instead of the given name.
-   -  In :doc:`Database Forge <database/forge>` the name can be omitted
-      from $this->dbforge->modify_column()'s 2nd param if you aren't
-      changing the name.
-   -  $config['base_url'] is now empty by default and will guess what
-      it should be.
-   -  Enabled full Command Line Interface compatibility with
-      config['uri_protocol'] = 'CLI';.

-Version 1.7
-===========
-
-Release Date: October 23, 2008
-Hg Tag: 1.7.0
-
--  Libraries
-
-   -  Added a new :doc:`Form Validation
-      Class <libraries/form_validation>`. It simplifies setting
-      rules and field names, supports arrays as field names, allows
-      groups of validation rules to be saved in a config file, and adds
-      some helper functions for use in view files. **Please note that
-      the old Validation class is now deprecated**. We will leave it in
-      the library folder for some time so that existing applications
-      that use it will not break, but you are encouraged to migrate to
-      the new version.
-   -  Updated the :doc:`Sessions class <libraries/sessions>` so that
-      any custom data being saved gets stored to a database rather than
-      the session cookie (assuming you are using a database to store
-      session data), permitting much more data to be saved.
-   -  Added the ability to store libraries in subdirectories within
-      either the main "libraries" or the local application "libraries"
-      folder. Please see the :doc:`Loader class <libraries/loader>` for
-      more info.
-   -  Added the ability to assign library objects to your own variable
-      names when you use $this->load->library(). Please see the :doc:`Loader
-      class <libraries/loader>` for more info.
-   -  Added controller class/method info to :doc:`Profiler
-      class <general/profiling>` and support for multiple database
-      connections.
-   -  Improved the "auto typography" feature and moved it out of the
-      helper into its own :doc:`Typography
-      Class <libraries/typography>`.
-   -  Improved performance and accuracy of xss_clean(), including
-      reduction of false positives on image/file tests.
-   -  Improved :doc:`Parser class <./libraries/parser>` to allow
-      multiple calls to the parse() function. The output of each is
-      appended in the output.
-   -  Added max_filename option to set a file name length limit in the
-      :doc:`File Upload Class <libraries/file_uploading>`.
-   -  Added set_status_header() function to :doc:`Output
-      class <libraries/output>`.
-   -  Modified :doc:`Pagination <libraries/pagination>` class to only
-      output the "First" link when the link for page one would not be
-      shown.
-   -  Added support for mb_strlen in the :doc:`Form
-      Validation <libraries/form_validation>` class so that
-      multi-byte languages will calculate string lengths properly.
-
--  Database
-
-   -  Improved Active Record class to allow full path column and table
-      names: hostname.database.table.column. Also improved the alias
-      handling.
-   -  Improved how table and column names are escaped and prefixed. It
-      now honors full path names when adding prefixes and escaping.
-   -  Added Active Record caching feature to "update" and "delete"
-      functions.
-   -  Added removal of non-printing control characters in escape_str()
-      of DB drivers that do not have native PHP escaping mechanisms
-      (mssql, oci8, odbc), to avoid potential SQL errors, and possible
-      sources of SQL injection.
-   -  Added port support to MySQL, MySQLi, and MS SQL database drivers.
-   -  Added driver name variable in each DB driver, based on bug report
-      #4436.
-
--  Helpers
-
-   -  Added several new "setting" functions to the :doc:`Form
-      helper <helpers/form_helper>` that allow POST data to be
-      retrieved and set into forms. These are intended to be used on
-      their own, or with the new :doc:`Form Validation
-      Class <libraries/form_validation>`.
-   -  Added current_url() and uri_segments() to :doc:`URL
-      helper <helpers/url_helper>`.
-   -  Altered auto_link() in the :doc:`URL
-      helper <helpers/url_helper>` so that email addresses with
-      "+" included will be linked.
-   -  Added meta() function to :doc:`HTML
-      helper <helpers/html_helper>`.
-   -  Improved accuracy of calculations in :doc:`Number
-      helper <helpers/number_helper>`.
-   -  Removed added newlines ("\\n") from most form and html helper
-      functions.
-   -  Tightened up validation in the :doc:`Date
-      helper <helpers/date_helper>` function human_to_unix(),
-      and eliminated the POSIX regex.
-   -  Updated :doc:`Date helper <helpers/date_helper>` to match the
-      world's current time zones and offsets.
-   -  Modified url_title() in the :doc:`URL
-      helper <helpers/url_helper>` to remove characters and digits
-      that are part of character entities, to allow dashes, underscores,
-      and periods regardless of the $separator, and to allow uppercase
-      characters.
-   -  Added support for arbitrary attributes in anchor_popup() of the
-      :doc:`URL helper <helpers/url_helper>`.
-
--  Other Changes
-
-   -  Added :doc:`PHP Style Guide <./general/styleguide>` to docs.
-   -  Added sanitization in xss_clean() for a deprecated HTML tag that
-      could be abused in user input in Internet Explorer.
-   -  Added a few openxml document mime types, and an additional mobile
-      agent to mimes.php and user_agents.php respectively.
-   -  Added a file lock check during caching, before trying to write to
-      the file.
-   -  Modified Cookie key cleaning to unset a few troublesome key names
-      that can be present in certain environments, preventing CI from
-      halting execution.
-   -  Changed the output of the profiler to use style attribute rather
-      than clear, and added the id "codeigniter_profiler" to the
-      container div.

-   Routing <general/routing>` feature. Previously, the URI class did not
-   permit you to access any re-routed URI segments, but now it does.
--  Added :doc:`$this->output->set_header() <./libraries/output>`
-   function, which allows you to set server headers.
--  Updated plugins, helpers, and language classes to allow your
-   application folder to contain its own plugins, helpers, and language
-   folders. Previously they were always treated as global for your
-   entire installation. If your application folder contains any of these
-   resources they will be used *instead* the global ones.
--  Added :doc:`Inflector helper <./helpers/inflector_helper>`.
--  Added element() function in the :doc:`array
-   helper <./helpers/array_helper>`.
--  Added RAND() to active record orderby() function.
--  Added delete_cookie() and get_cookie() to :doc:`Cookie
-   helper <./helpers/cookie_helper>`, even though the input class
-   has a cookie fetching function.
--  Added Oracle database driver (still undergoing testing so it might
-   have some bugs).
--  Added the ability to combine pseudo-variables and php variables in
-   the template parser class.
--  Added output compression option to the config file.
--  Removed the is_numeric test from the db->escape() function.
--  Fixed a MySQLi bug that was causing error messages not to contain
-   proper error data.
--  Fixed a bug in the email class which was causing it to ignore
-   explicitly set alternative headers.
--  Fixed a bug that was causing a PHP error when the Exceptions class
-   was called within the get_config() function since it was causing
-   problems.
--  Fixed an oversight in the cookie helper in which the config file
-   cookie settings were not being honored.
--  Fixed an oversight in the upload class. An item mentioned in the 1.4
-   changelog was missing.
--  Added some code to allow email attachments to be reset when sending
-   batches of email.
--  Deprecated the application/scripts folder. It will continue to work
-   for legacy users, but it is recommended that you create your own
-   :doc:`libraries <./general/libraries>` or
-   :doc:`models <./general/models>` instead. It was originally added
-   before CI had user libraries or models, but it's not needed anymore.
--  Deprecated the $autoload['core'] item from the autoload.php file.
-   Instead, please now use: $autoload['libraries']
--  Deprecated the following database functions:
-   $this->db->smart_escape_str() and $this->db->fields().
-
-Version 1.4.0
-=============
-
-Release Date: September 17, 2006
-
--  Added :doc:`Hooks <./general/hooks>` feature, enabling you to tap
-   into and modify the inner workings of the framework without hacking
-   the core files.
--  Added the ability to organize controller files :doc:`into
-   sub-folders <general/controllers>`. Kudos to Marco for
-   suggesting this (and the next two) feature.
--  Added regular expressions support for :doc:`routing
-   rules <./general/routing>`.
--  Added the ability to :doc:`remap function
-   calls <./general/controllers>` within your controllers.
--  Added the ability to :doc:`replace core system
-   classes <./general/core_classes>` with your own classes.
--  Added support for % character in URL.
--  Added the ability to supply full URLs using the
-   :doc:`anchor() <./helpers/url_helper>` helper function.

-   and into the config file.
--  Moved the MIME type array out of the Upload class and into its own
-   file in the application/config/ folder.
--  Updated the Upload class to allow the upload field name to be set
-   when calling :doc:`do_upload() <./libraries/file_uploading>`.
--  Updated the :doc:`Config Library <./libraries/config>` to be able to
-   load config files silently, and to be able to assign config files to
-   their own index (to avoid collisions if you use multiple config
-   files).
--  Updated the URI Protocol code to allow more options so that URLs will
-   work more reliably in different environments.
--  Updated the form_open() helper to allow the GET method to be used.
--  Updated the MySQLi execute() function with some code to help prevent
-   lost connection errors.
--  Updated the SQLite Driver to check for object support before

-   array.
--  Updated the Models loader function to allow multiple loads of the
-   same model.
--  Updated the MS SQL driver so that single quotes are escaped.
--  Updated the Postgres and ODBC drivers for better compatibility.
--  Removed a strtolower() call that was changing URL segments to lower
-   case.
--  Removed some references that were interfering with PHP 4.4.1
-   compatibility.
--  Removed backticks from Postgres class since these are not needed.
--  Renamed display() to _display() in the Output class to make it clear
-   that it's a private function.
--  Deprecated the hash() function due to a naming conflict with a native
-   PHP function with the same name. Please use dohash() instead.

-   variables.
--  Fixed a router bug that was making it too greedy when matching end
-   segments.
--  Fixed a bug that was preventing multiple discrete database calls.

-
-Version 1.3.3
-=============
-
-Release Date: June 1, 2006
-
--  Models do **not** connect automatically to the database as of this
-   version. :doc:`More info here <./general/models>`.
--  Updated the Sessions class to utilize the active record class when
-   running session related queries. Previously the queries assumed MySQL
-   syntax.
--  Updated alternator() function to re-initialize when called with no
-   arguments, allowing multiple calls.
--  Fixed a bug in the active record "having" function.
--  Fixed a problem in the validation class which was making checkboxes
-   be ignored when required.

-   off the fist word.
--  Fixed a bug in the xss_clean function due to a PHP bug that affects
-   some versions of html_entity_decode.
--  Fixed a validation bug that was preventing rules from being set twice
-   in one controller.

-
-Version 1.3.2
-=============

-
--  Changed the behavior of the validation class such that if a
-   "required" rule is NOT explicitly stated for a field then all other
-   tests get ignored.
--  Fixed a bug in the Controller class that was causing it to look in
-   the local "init" folder instead of the main system one.
--  Fixed a bug in the init_pagination file. The $config item was not
-   being set correctly.
--  Fixed a bug in the auto typography helper that was causing
-   inconsistent behavior.
--  Fixed a couple bugs in the Model class.
--  Fixed some documentation typos and errata.
-
-Version 1.3.1
-=============
-
-Release Date: April 11, 2006
-
--  Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
--  Added the ability to pass objects to the **insert()** and
-   **update()** database functions. This feature enables you to (among
-   other things) use your :doc:`Model class <./general/models>`
-   variables to run queries with. See the Models page for details.
--  Added the ability to pass objects to the :doc:`view loading
-   function <./general/views>`: $this->load->view('my_view',
-   $object);
--  Added getwhere function to :doc:`Active Record
-   class <./database/query_builder>`.
--  Added count_all function to :doc:`Active Record
-   class <./database/query_builder>`.
--  Added language file for scaffolding and fixed a scaffolding bug that
-   occurs when there are no rows in the specified table.
--  Added :doc:`$this->db->last_query() <./database/queries>`, which
-   allows you to view your last query that was run.
--  Added a new mime type to the upload class for better compatibility.
--  Changed how cache files are read to prevent PHP errors if the cache
-   file contains an XML tag, which PHP wants to interpret as a short
-   tag.
--  Fixed a bug in a couple of the active record functions (where and
-   orderby).
--  Fixed a bug in the image library when realpath() returns false.
--  Fixed a bug in the Models that was preventing libraries from being
-   used within them.
--  Fixed a bug in the "exact_length" function of the validation class.
--  Fixed some typos in the user guide
-
-Version 1.3
-===========
-
-Release Date: April 3, 2006
-
--  Added support for :doc:`Models <general/models>`.
--  Redesigned the database libraries to support additional RDBMs
-   (Postgres, MySQLi, etc.).
--  Redesigned the :doc:`Active Record class <./database/query_builder>`
-   to enable more varied types of queries with simpler syntax, and
-   advanced features like JOINs.
--  Added a feature to the database class that lets you run :doc:`custom
-   function calls <./database/call_function>`.
--  Added support for :doc:`private functions <general/controllers>` in your
-   controllers. Any controller function name that starts with an
-   underscore will not be served by a URI request.
--  Added the ability to pass your own initialization parameters to your
-   :doc:`custom core libraries <general/creating_libraries>` when using
-   $this->load->library()
--  Added support for running standard :doc:`query string URLs <general/urls>`.
-   These can be optionally enabled in your config file.
--  Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
-   appended to your URLs. For example, you could add .html to your URLs,
-   making them appear static. This feature is enabled in your config
-   file.
--  Added a new error template for use with native PHP errors.
--  Added "alternator" function in the :doc:`string
-   helpers <./helpers/string_helper>`.
--  Removed slashing from the input class. After much debate we decided
-   to kill this feature.
--  Change the commenting style in the scripts to the PEAR standard so
-   that IDEs and tools like phpDocumenter can harvest the comments.
--  Added better class and function name-spacing to avoid collisions with
-   user developed classes. All CodeIgniter classes are now prefixed with
-   CI\_ and all controller methods are prefixed with _ci to avoid
-   controller collisions. A list of reserved function names can be
-   :doc:`found here <general/controllers>`.
--  Redesigned how the "CI" super object is referenced, depending on
-   whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
-   way to manage objects that utilizes a bit less resources.
--  Deprecated: $this->db->use_table() has been deprecated. Please read
-   the :doc:`Active Record <./database/query_builder>` page for
-   information.
--  Deprecated: $this->db->smart_escape_str() has been deprecated.
-   Please use this instead: $this->db->escape()
--  Fixed a bug in the exception handler which was preventing some PHP
-   errors from showing up.
--  Fixed a typo in the URI class. $this->total_segment() should be
-   plural: $this->total_segments()
--  Fixed some typos in the default calendar template
--  Fixed some typos in the user guide
-
-Version 1.2
-===========
-
-Release Date: March 21, 2006
-
--  Redesigned some internal aspects of the framework to resolve scoping
-   problems that surfaced during the beta tests. The problem was most
-   notable when instantiating classes in your constructors, particularly
-   if those classes in turn did work in their constructors.
--  Added a global function named
-   :doc:`get_instance() <general/ancillary_classes>` allowing the main
-   CodeIgniter object to be accessible throughout your own classes.
--  Added new :doc:`File Helper <./helpers/file_helper>`:
-   delete_files()
--  Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
-   index_page()
--  Added the ability to create your own :doc:`core
-   libraries <general/creating_libraries>` and store them in your local
-   application directory.
--  Added an overwrite option to the :doc:`Upload
-   class <./libraries/file_uploading>`, enabling files to be
-   overwritten rather than having the file name appended.
--  Added Javascript Calendar plugin.
--  Added search feature to user guide. Note: This is done using Google,
-   which at the time of this writing has not crawled all the pages of
-   the docs.
--  Updated the parser class so that it allows tag pars within other tag
-   pairs.
--  Fixed a bug in the DB "where" function.
--  Fixed a bug that was preventing custom config files to be
-   auto-loaded.
--  Fixed a bug in the mysql class bind feature that prevented question
-   marks in the replacement data.
--  Fixed some bugs in the xss_clean function
-
-Version Beta 1.1
-================
-
-Release Date: March 10, 2006
-
--  Added a :doc:`Calendaring class <./libraries/calendar>`.
--  Added support for running :doc:`multiple
-   applications <general/managing_apps>` that share a common CodeIgniter
-   backend.
--  Moved the "uri protocol" variable from the index.php file into the
-   config.php file
--  Fixed a problem that was preventing certain function calls from
-   working within constructors.
--  Fixed a problem that was preventing the $this->load->library function
-   from working in constructors.
--  Fixed a bug that occurred when the session class was loaded using the
-   auto-load routine.
--  Fixed a bug that can happen with PHP versions that do not support the
-   E_STRICT constant
--  Fixed a data type error in the form_radio function (form helper)
--  Fixed a bug that was preventing the xss_clean function from being
-   called from the validation class.
--  Fixed the cookie related config names, which were incorrectly
-   specified as $conf rather than $config
--  Fixed a pagination problem in the scaffolding.
--  Fixed a bug in the mysql class "where" function.
--  Fixed a regex problem in some code that trimmed duplicate slashes.
--  Fixed a bug in the br() function in the HTML helper
--  Fixed a syntax mistake in the form_dropdown function in the Form
-   Helper.
--  Removed the "style" attributes form the form helpers.
--  Updated the documentation. Added "next/previous" links to each page
-   and fixed various typos.

-
-CodeIgniter is a community driven project and accepts contributions of code
-and documentation from the community. These contributions are made in the form
-of Issues or `Pull Requests <https://help.github.com/articles/using-pull-requests/>`_ 
-on the `CodeIgniter repository <https://github.com/bcit-ci/CodeIgniter>`_ on GitHub.
-
-Issues are a quick way to point out a bug. If you find a bug or documentation
-error in CodeIgniter then please check a few things first:
-
-- There is not already an open Issue
-- The issue has already been fixed (check the develop branch, or look for
-  closed Issues)
-- Is it something really obvious that you fix it yourself?
-
-Reporting issues is helpful but an even better approach is to send a Pull
-Request, which is done by "Forking" the main repository and committing to your
-own copy. This will require you to use the version control system called Git.

-Did you find a security issue in CodeIgniter?
-
-Please *don't* disclose it publicly, but e-mail us at security@codeigniter.com,
-or report it via our page on `HackerOne <https://hackerone.com/codeigniter>`_.

-****************************
-Tips for a Good Issue Report
-****************************
-
-Use a descriptive subject line (eg parser library chokes on commas) rather than a vague one (eg. your code broke).
-
-Address a single issue in a report.
-
-Identify the CodeIgniter version (eg 3.0-develop) and the component if you know it (eg. parser library)
-
-Explain what you expected to happen, and what did happen.
-Include error messages and stacktrace, if any.
-
-Include short code segments if they help to explain.
-Use a pastebin or dropbox facility to include longer segments of code or screenshots - do not include them in the issue report itself.
-This means setting a reasonable expiry for those, until the issue is resolved or closed.
-
-If you know how to fix the issue, you can do so in your own fork & branch, and submit a pull request.
-The issue report information above should be part of that.
-
-If your issue report can describe the steps to reproduce the problem, that is great.
-If you can include a unit test that reproduces the problem, that is even better, as it gives whoever is fixing
-it a clearer target!
-
-
-**********
-Guidelines
-**********
-
-Before we look into how, here are the guidelines. If your Pull Requests fail
-to pass these guidelines it will be declined and you will need to re-submit
-when you’ve made the changes. This might sound a bit tough, but it is required
-for us to maintain quality of the code-base.
-
-PHP Style
-=========
-
-All code must meet the `Style Guide
-<https://codeigniter.com/userguide3/general/styleguide.html>`_, which is
-essentially the `Allman indent style
-<https://en.wikipedia.org/wiki/Indent_style#Allman_style>`_, underscores and
-readable operators. This makes certain that all code is the same format as the
-existing code and means it will be as readable as possible.
-
-Documentation
-=============
-
-If you change anything that requires a change to documentation then you will
-need to add it. New classes, methods, parameters, changing default values, etc
-are all things that will require a change to documentation. The change-log
-must also be updated for every change. Also PHPDoc blocks must be maintained.
-
-Compatibility
-=============
-
-CodeIgniter recommends PHP 5.6 or newer to be used, but it should be
-compatible with PHP 5.3.7 so all code supplied must stick to this
-requirement. If PHP 5.4 (and above) functions or features are used then
-there must be a fallback for PHP 5.3.7.
-
-Branching
-=========
-
-CodeIgniter uses the `Git-Flow
-<http://nvie.com/posts/a-successful-git-branching-model/>`_ branching model
-which requires all pull requests to be sent to the "develop" branch. This is
-where the next planned version will be developed. The "master" branch will
-always contain the latest stable version and is kept clean so a "hotfix" (e.g:
-an emergency security patch) can be applied to master to create a new version,
-without worrying about other features holding it up. For this reason all
-commits need to be made to "develop" and any sent to "master" will be closed
-automatically. If you have multiple changes to submit, please place all
-changes into their own branch on your fork.
-
-One thing at a time: A pull request should only contain one change. That does
-not mean only one commit, but one change - however many commits it took. The
-reason for this is that if you change X and Y but send a pull request for both
-at the same time, we might really want X but disagree with Y, meaning we
-cannot merge the request. Using the Git-Flow branching model you can create
-new branches for both of these features and send two requests.
-
-Signing
-=======
-You must sign your work, certifying that you either wrote the work or
-otherwise have the right to pass it on to an open source project. git makes
-this trivial as you merely have to use `--signoff` on your commits to your
-CodeIgniter fork.
-
-.. code-block:: bash
-
-	git commit --signoff
-
-or simply
-
-.. code-block:: bash
-
-	git commit -s
-
-This will sign your commits with the information setup in your git config, e.g.
-
-	Signed-off-by: John Q Public <john.public@example.com>
-
-If you are using Tower there is a "Sign-Off" checkbox in the commit window. You
-could even alias git commit to use the -s flag so you don’t have to think about
-it.
-
-By signing your work in this manner, you certify to a "Developer's Certificate
-of Origin". The current version of this certificate is in the :doc:`/DCO` file
-in the root of this documentation.

-######################
-Database Caching Class
-######################
-
-The Database Caching Class permits you to cache your queries as text
-files for reduced database load.
-
-.. important:: This class is initialized automatically by the database
-	driver when caching is enabled. Do NOT load this class manually.
-
-.. important:: Not all query result functions are available when you
-	use caching. Please read this page carefully.
-
-Enabling Caching
-================
-
-Caching is enabled in three steps:
-
--  Create a writable directory on your server where the cache files can
-   be stored.
--  Set the path to your cache folder in your
-   application/config/database.php file.
--  Enable the caching feature, either globally by setting the preference
-   in your application/config/database.php file, or manually as
-   described below.
-
-Once enabled, caching will happen automatically whenever a page is
-loaded that contains database queries.
-
-How Does Caching Work?
-======================
-
-CodeIgniter's query caching system happens dynamically when your pages
-are viewed. When caching is enabled, the first time a web page is
-loaded, the query result object will be serialized and stored in a text
-file on your server. The next time the page is loaded the cache file
-will be used instead of accessing your database. Your database usage can
-effectively be reduced to zero for any pages that have been cached.
-
-Only read-type (SELECT) queries can be cached, since these are the only
-type of queries that produce a result. Write-type (INSERT, UPDATE, etc.)
-queries, since they don't generate a result, will not be cached by the
-system.
-
-Cache files DO NOT expire. Any queries that have been cached will remain
-cached until you delete them. The caching system permits you clear
-caches associated with individual pages, or you can delete the entire
-collection of cache files. Typically you'll want to use the housekeeping
-functions described below to delete cache files after certain events
-take place, like when you've added new information to your database.
-
-Will Caching Improve Your Site's Performance?
-=============================================
-
-Getting a performance gain as a result of caching depends on many
-factors. If you have a highly optimized database under very little load,
-you probably won't see a performance boost. If your database is under
-heavy use you probably will see an improved response, assuming your
-file-system is not overly taxed. Remember that caching simply changes
-how your information is retrieved, shifting it from being a database
-operation to a file-system one.
-
-In some clustered server environments, for example, caching may be
-detrimental since file-system operations are so intense. On single
-servers in shared environments, caching will probably be beneficial.
-Unfortunately there is no single answer to the question of whether you
-should cache your database. It really depends on your situation.
-
-How are Cache Files Stored?
-===========================
-
-CodeIgniter places the result of EACH query into its own cache file.
-Sets of cache files are further organized into sub-folders corresponding
-to your controller functions. To be precise, the sub-folders are named
-identically to the first two segments of your URI (the controller class
-name and function name).
-
-For example, let's say you have a controller called blog with a function
-called comments that contains three queries. The caching system will
-create a cache folder called blog+comments, into which it will write
-three cache files.
-
-If you use dynamic queries that change based on information in your URI
-(when using pagination, for example), each instance of the query will
-produce its own cache file. It's possible, therefore, to end up with
-many times more cache files than you have queries.
-
-Managing your Cache Files
-=========================
-
-Since cache files do not expire, you'll need to build deletion routines
-into your application. For example, let's say you have a blog that
-allows user commenting. Whenever a new comment is submitted you'll want
-to delete the cache files associated with the controller function that
-serves up your comments. You'll find two delete functions described
-below that help you clear data.
-
-Not All Database Functions Work with Caching
-============================================
-
-Lastly, we need to point out that the result object that is cached is a
-simplified version of the full result object. For that reason, some of
-the query result functions are not available for use.
-
-The following functions ARE NOT available when using a cached result
-object:
-
--  num_fields()
--  field_names()
--  field_data()
--  free_result()
-
-Also, the two database resources (result_id and conn_id) are not
-available when caching, since result resources only pertain to run-time
-operations.
-
-******************
-Function Reference
-******************
-
-$this->db->cache_on() / $this->db->cache_off()
-================================================
-
-Manually enables/disables caching. This can be useful if you want to
-keep certain queries from being cached. Example::
-
-	// Turn caching on
-	$this->db->cache_on();
-	$query = $this->db->query("SELECT * FROM mytable");
-	
-	// Turn caching off for this one query
-	$this->db->cache_off();
-	$query = $this->db->query("SELECT * FROM members WHERE member_id = '$current_user'");
-	
-	// Turn caching back on
-	$this->db->cache_on();
-	$query = $this->db->query("SELECT * FROM another_table");
-
-$this->db->cache_delete()
-==========================
-
-Deletes the cache files associated with a particular page. This is
-useful if you need to clear caching after you update your database.
-
-The caching system saves your cache files to folders that correspond to
-the URI of the page you are viewing. For example, if you are viewing a
-page at example.com/index.php/blog/comments, the caching system will put
-all cache files associated with it in a folder called blog+comments. To
-delete those particular cache files you will use::
-
-	$this->db->cache_delete('blog', 'comments');
-
-If you do not use any parameters the current URI will be used when
-determining what should be cleared.
-
-$this->db->cache_delete_all()
-===============================
-
-Clears all existing cache files. Example::
-
-	$this->db->cache_delete_all();

-#####################
-Custom Function Calls
-#####################
-
-$this->db->call_function();
-============================
-
-This function enables you to call PHP database functions that are not
-natively included in CodeIgniter, in a platform independent manner. For
-example, let's say you want to call the mysql_get_client_info()
-function, which is **not** natively supported by CodeIgniter. You could
-do so like this::
-
-	$this->db->call_function('get_client_info');
-
-You must supply the name of the function, **without** the mysql\_
-prefix, in the first parameter. The prefix is added automatically based
-on which database driver is currently being used. This permits you to
-run the same function on different database platforms. Obviously not all
-function calls are identical between platforms, so there are limits to
-how useful this function can be in terms of portability.
-
-Any parameters needed by the function you are calling will be added to
-the second parameter.
-
-::
-
-	$this->db->call_function('some_function', $param1, $param2, etc..);
-
-Often, you will either need to supply a database connection ID or a
-database result ID. The connection ID can be accessed using::
-
-	$this->db->conn_id;
-
-The result ID can be accessed from within your result object, like this::
-
-	$query = $this->db->query("SOME QUERY");
-	
-	$query->result_id;

-######################
-Database Configuration
-######################
-
-CodeIgniter has a config file that lets you store your database
-connection values (username, password, database name, etc.). The config
-file is located at application/config/database.php. You can also set
-database connection values for specific
-:doc:`environments <../libraries/config>` by placing **database.php**
-in the respective environment config folder.
-
-The config settings are stored in a multi-dimensional array with this
-prototype::
-
-	$db['default'] = array(
-		'dsn'	=> '',
-		'hostname' => 'localhost',
-		'username' => 'root',
-		'password' => '',
-		'database' => 'database_name',
-		'dbdriver' => 'mysqli',
-		'dbprefix' => '',
-		'pconnect' => TRUE,
-		'db_debug' => TRUE,
-		'cache_on' => FALSE,
-		'cachedir' => '',
-		'char_set' => 'utf8',
-		'dbcollat' => 'utf8_general_ci',
-		'swap_pre' => '',
-		'encrypt' => FALSE,
-		'compress' => FALSE,
-		'stricton' => FALSE,
-		'failover' => array()
-	);
-
-Some database drivers (such as PDO, PostgreSQL, Oracle, ODBC) might
-require a full DSN string to be provided. If that is the case, you
-should use the 'dsn' configuration setting, as if you're using the
-driver's underlying native PHP extension, like this::
-
-	// PDO
-	$db['default']['dsn'] = 'pgsql:host=localhost;port=5432;dbname=database_name';
-
-	// Oracle
-	$db['default']['dsn'] = '//localhost/XE';
-
-.. note:: If you do not specify a DSN string for a driver that requires it, CodeIgniter
-	will try to build it with the rest of the provided settings.
-
-.. note:: If you provide a DSN string and it is missing some valid settings (e.g. the
-	database character set), which are present in the rest of the configuration
-	fields, CodeIgniter will append them.
-
-You can also specify failovers for the situation when the main connection cannot connect for some reason.
-These failovers can be specified by setting the failover for a connection like this::
-
-	$db['default']['failover'] = array(
-			array(
-				'hostname' => 'localhost1',
-				'username' => '',
-				'password' => '',
-				'database' => '',
-				'dbdriver' => 'mysqli',
-				'dbprefix' => '',
-				'pconnect' => TRUE,
-				'db_debug' => TRUE,
-				'cache_on' => FALSE,
-				'cachedir' => '',
-				'char_set' => 'utf8',
-				'dbcollat' => 'utf8_general_ci',
-				'swap_pre' => '',
-				'encrypt' => FALSE,
-				'compress' => FALSE,
-				'stricton' => FALSE
-			),
-			array(
-				'hostname' => 'localhost2',
-				'username' => '',
-				'password' => '',
-				'database' => '',
-				'dbdriver' => 'mysqli',
-				'dbprefix' => '',
-				'pconnect' => TRUE,
-				'db_debug' => TRUE,
-				'cache_on' => FALSE,
-				'cachedir' => '',
-				'char_set' => 'utf8',
-				'dbcollat' => 'utf8_general_ci',
-				'swap_pre' => '',
-				'encrypt' => FALSE,
-				'compress' => FALSE,
-				'stricton' => FALSE
-			)
-		);
-
-You can specify as many failovers as you like.
-
-The reason we use a multi-dimensional array rather than a more simple
-one is to permit you to optionally store multiple sets of connection
-values. If, for example, you run multiple environments (development,
-production, test, etc.) under a single installation, you can set up a
-connection group for each, then switch between groups as needed. For
-example, to set up a "test" environment you would do this::
-
-	$db['test'] = array(
-		'dsn'	=> '',
-		'hostname' => 'localhost',
-		'username' => 'root',
-		'password' => '',
-		'database' => 'database_name',
-		'dbdriver' => 'mysqli',
-		'dbprefix' => '',
-		'pconnect' => TRUE,
-		'db_debug' => TRUE,
-		'cache_on' => FALSE,
-		'cachedir' => '',
-		'char_set' => 'utf8',
-		'dbcollat' => 'utf8_general_ci',
-		'swap_pre' => '',
-		'compress' => FALSE,
-		'encrypt' => FALSE,
-		'stricton' => FALSE,
-		'failover' => array()
-	);
-
-Then, to globally tell the system to use that group you would set this
-variable located in the config file::
-
-	$active_group = 'test';
-
-.. note:: The name 'test' is arbitrary. It can be anything you want. By
-	default we've used the word "default" for the primary connection,
-	but it too can be renamed to something more relevant to your project.
-
-Query Builder
--------------
-
-The :doc:`Query Builder Class <query_builder>` is globally enabled or
-disabled by setting the $query_builder variable in the database
-configuration file to TRUE/FALSE (boolean). The default setting is TRUE.
-If you are not using the
-query builder class, setting it to FALSE will utilize fewer resources
-when the database classes are initialized.
-
-::
-
-	$query_builder = TRUE;
-
-.. note:: that some CodeIgniter classes such as Sessions require Query
-	Builder to be enabled to access certain functionality.
-
-Explanation of Values:

-###########################
-Connecting to your Database
-###########################
-
-There are two ways to connect to a database:
-
-Automatically Connecting
-========================
-
-The "auto connect" feature will load and instantiate the database class
-with every page load. To enable "auto connecting", add the word database
-to the library array, as indicated in the following file:
-
-application/config/autoload.php
-
-Manually Connecting
-===================
-
-If only some of your pages require database connectivity you can
-manually connect to your database by adding this line of code in any
-function where it is needed, or in your class constructor to make the
-database available globally in that class.
-
-::
-
-	$this->load->database();
-
-If the above function does **not** contain any information in the first
-parameter it will connect to the group specified in your database config
-file. For most people, this is the preferred method of use.
-
-Available Parameters
---------------------
-
-#. The database connection values, passed either as an array or a DSN
-   string.
-#. TRUE/FALSE (boolean). Whether to return the connection ID (see
-   Connecting to Multiple Databases below).
-#. TRUE/FALSE (boolean). Whether to enable the Query Builder class. Set
-   to TRUE by default.
-
-Manually Connecting to a Database
----------------------------------
-
-The first parameter of this function can **optionally** be used to
-specify a particular database group from your config file, or you can
-even submit connection values for a database that is not specified in
-your config file. Examples:
-
-To choose a specific group from your config file you can do this::
-
-	$this->load->database('group_name');
-
-Where group_name is the name of the connection group from your config
-file.
-
-To connect manually to a desired database you can pass an array of
-values::
-
-	$config['hostname'] = 'localhost';
-	$config['username'] = 'myusername';
-	$config['password'] = 'mypassword';
-	$config['database'] = 'mydatabase';
-	$config['dbdriver'] = 'mysqli';
-	$config['dbprefix'] = '';
-	$config['pconnect'] = FALSE;
-	$config['db_debug'] = TRUE;
-	$config['cache_on'] = FALSE;
-	$config['cachedir'] = '';
-	$config['char_set'] = 'utf8';
-	$config['dbcollat'] = 'utf8_general_ci';
-	$this->load->database($config);
-
-For information on each of these values please see the :doc:`configuration
-page <configuration>`.
-
-.. note:: For the PDO driver, you should use the $config['dsn'] setting
-	instead of 'hostname' and 'database':
-
-	|
-	| $config['dsn'] = 'mysql:host=localhost;dbname=mydatabase';
-
-Or you can submit your database values as a Data Source Name. DSNs must
-have this prototype::
-
-	$dsn = 'dbdriver://username:password@hostname/database';  
-	$this->load->database($dsn);
-
-To override default config values when connecting with a DSN string, add
-the config variables as a query string.
-
-::
-
-	$dsn = 'dbdriver://username:password@hostname/database?char_set=utf8&dbcollat=utf8_general_ci&cache_on=true&cachedir=/path/to/cache';  
-	$this->load->database($dsn);
-
-Connecting to Multiple Databases
-================================
-
-If you need to connect to more than one database simultaneously you can
-do so as follows::
-
-	$DB1 = $this->load->database('group_one', TRUE); 
-	$DB2 = $this->load->database('group_two', TRUE);
-
-Note: Change the words "group_one" and "group_two" to the specific
-group names you are connecting to (or you can pass the connection values
-as indicated above).
-
-By setting the second parameter to TRUE (boolean) the function will
-return the database object.
-
-.. note:: When you connect this way, you will use your object name to issue
-	commands rather than the syntax used throughout this guide. In other
-	words, rather than issuing commands with:
-	
-	|
-	| $this->db->query();
-	| $this->db->result();
-	| etc...
-	|
-	| You will instead use:
-	|
-	| $DB1->query();
-	| $DB1->result();
-	| etc...
-
-.. note:: You don't need to create separate database configurations if you
-	only need to use a different database on the same connection. You
-	can switch to a different database when you need to, like this:
-
-	| $this->db->db_select($database2_name);
-
-Reconnecting / Keeping the Connection Alive
-===========================================
-
-If the database server's idle timeout is exceeded while you're doing
-some heavy PHP lifting (processing an image, for instance), you should
-consider pinging the server by using the reconnect() method before
-sending further queries, which can gracefully keep the connection alive
-or re-establish it.
-
-::
-
-	$this->db->reconnect();
-
-Manually closing the Connection
-===============================
-
-While CodeIgniter intelligently takes care of closing your database
-connections, you can explicitly close the connection.
-
-::
-
-	$this->db->close();

-			around them.
-
-	.. php:method:: escape_like_str($str)
-
-		:param	mixed	$str: A string value or array of multiple ones

-
-		Escape LIKE strings.
-
-		Similar to ``escape_str()``, but will also escape the ``%``
-		and ``_`` wildcard characters, so that they don't cause
-		false-positives in LIKE conditions.
-
-		.. important:: The ``escape_like_str()`` method uses '!' (exclamation mark)
-			to escape special characters for *LIKE* conditions. Because this

-
-		Close the DB Connection.
-
-	.. php:method:: display_error([$error = ''[, $swap = ''[, $native = FALSE]]])

-		:returns:	The modified item
-		:rtype:	string
-
-		Takes a column or table name (optionally with an alias)
-		and applies the configured *dbprefix* to it.
-
-		Some logic is necessary in order to deal with
-		column names that include the path. 
-
-		Consider a query like this::
-
-			SELECT * FROM hostname.database.table.column AS c FROM hostname.database.table
-
-		Or a query with aliasing::
-
-			SELECT m.member_id, m.member_name FROM members AS m
-
-		Since the column name can include up to four segments
-		(host, DB, table, column) or also have an alias prefix,
-		we need to do a bit of work to figure this out and
-		insert the table prefix (if it exists) in the proper
-		position, and escape only the correct identifiers.
-
-		This method is used extensively by the Query Builder class.

-##################################
-Database Quick Start: Example Code
-##################################
-
-The following page contains example code showing how the database class
-is used. For complete details please read the individual pages
-describing each function.
-
-Initializing the Database Class
-===============================
-
-The following code loads and initializes the database class based on
-your :doc:`configuration <configuration>` settings::
-
-	$this->load->database();
-
-Once loaded the class is ready to be used as described below.
-
-Note: If all your pages require database access you can connect
-automatically. See the :doc:`connecting <connecting>` page for details.
-
-Standard Query With Multiple Results (Object Version)
-=====================================================
-
-::
-
-	$query = $this->db->query('SELECT name, title, email FROM my_table');
-	
-	foreach ($query->result() as $row)
-	{
-		echo $row->title;
-		echo $row->name;
-		echo $row->email;
-	}
-	
-	echo 'Total Results: ' . $query->num_rows();
-
-The above result() function returns an array of **objects**. Example:
-$row->title
-
-Standard Query With Multiple Results (Array Version)
-====================================================
-
-::
-
-	$query = $this->db->query('SELECT name, title, email FROM my_table');
-	
-	foreach ($query->result_array() as $row)
-	{
-		echo $row['title'];
-		echo $row['name'];
-		echo $row['email'];
-	}
-
-The above result_array() function returns an array of standard array
-indexes. Example: $row['title']
-
-Standard Query With Single Result
-=================================
-
-::
-
-	$query = $this->db->query('SELECT name FROM my_table LIMIT 1'); 
-	$row = $query->row();
-	echo $row->name;
-
-The above row() function returns an **object**. Example: $row->name
-
-Standard Query With Single Result (Array version)
-=================================================
-
-::
-
-	$query = $this->db->query('SELECT name FROM my_table LIMIT 1');
-	$row = $query->row_array();
-	echo $row['name'];
-
-The above row_array() function returns an **array**. Example:
-$row['name']
-
-Standard Insert
-===============
-
-::
-
-	$sql = "INSERT INTO mytable (title, name) VALUES (".$this->db->escape($title).", ".$this->db->escape($name).")";
-	$this->db->query($sql);
-	echo $this->db->affected_rows();
-
-Query Builder Query
-===================
-
-The :doc:`Query Builder Pattern <query_builder>` gives you a simplified
-means of retrieving data::
-
-	$query = $this->db->get('table_name');
-	
-	foreach ($query->result() as $row)
-	{
-		echo $row->title;
-	}
-
-The above get() function retrieves all the results from the supplied
-table. The :doc:`Query Builder <query_builder>` class contains a full
-compliment of functions for working with data.
-
-Query Builder Insert
-====================
-
-::
-
-	$data = array(
-		'title' => $title,
-		'name' => $name,
-		'date' => $date
-	);
-	
-	$this->db->insert('mytable', $data);  // Produces: INSERT INTO mytable (title, name, date) VALUES ('{$title}', '{$name}', '{$date}')

-Database Forge Class
-####################
-
-The Database Forge Class contains methods that help you manage your
-database.
-
-.. contents:: Table of Contents
-    :depth: 3
-
-****************************
-Initializing the Forge Class
-****************************
-
-.. important:: In order to initialize the Forge class, your database
-	driver must already be running, since the forge class relies on it.
-
-Load the Forge Class as follows::
-
-	$this->load->dbforge()
-
-You can also pass another database object to the DB Forge loader, in case
-the database you want to manage isn't the default one::
-
-	$this->myforge = $this->load->dbforge($this->other_db, TRUE);
-
-In the above example, we're passing a custom database object as the first
-parameter and then tell it to return the dbforge object, instead of
-assigning it directly to ``$this->dbforge``.
-
-.. note:: Both of the parameters can be used individually, just pass an empty
-	value as the first one if you wish to skip it.
-
-Once initialized you will access the methods using the ``$this->dbforge``
-object::
-
-	$this->dbforge->some_method();
-
-*******************************
-Creating and Dropping Databases
-*******************************
-
-**$this->dbforge->create_database('db_name')**
-
-Permits you to create the database specified in the first parameter.
-Returns TRUE/FALSE based on success or failure::
-
-	if ($this->dbforge->create_database('my_db'))
-	{
-		echo 'Database created!';
-	}
-
-**$this->dbforge->drop_database('db_name')**
-
-Permits you to drop the database specified in the first parameter.
-Returns TRUE/FALSE based on success or failure::
-
-	if ($this->dbforge->drop_database('my_db'))
-	{
-		echo 'Database deleted!';
-	}
-
-
-****************************
-Creating and Dropping Tables
-****************************
-
-There are several things you may wish to do when creating tables. Add
-fields, add keys to the table, alter columns. CodeIgniter provides a
-mechanism for this.
-
-Adding fields
-=============
-
-Fields are created via an associative array. Within the array you must
-include a 'type' key that relates to the datatype of the field. For
-example, INT, VARCHAR, TEXT, etc. Many datatypes (for example VARCHAR)
-also require a 'constraint' key.
-
-::
-
-	$fields = array(
-		'users' => array(
-			'type' => 'VARCHAR',
-			'constraint' => '100',
-		),
-	);
-	// will translate to "users VARCHAR(100)" when the field is added.
-
-
-Additionally, the following key/values can be used:
-
--  unsigned/true : to generate "UNSIGNED" in the field definition.
--  default/value : to generate a default value in the field definition.
--  null/true : to generate "NULL" in the field definition. Without this,
-   the field will default to "NOT NULL".
--  auto_increment/true : generates an auto_increment flag on the
-   field. Note that the field type must be a type that supports this,
-   such as integer.
--  unique/true : to generate a unique key for the field definition.
-
-::
-
-	$fields = array(
-		'blog_id' => array(
-			'type' => 'INT',
-			'constraint' => 5,
-			'unsigned' => TRUE,
-			'auto_increment' => TRUE
-		),
-		'blog_title' => array(
-			'type' => 'VARCHAR',
-			'constraint' => '100',
-			'unique' => TRUE,
-		),
-		'blog_author' => array(
-			'type' =>'VARCHAR',
-			'constraint' => '100',
-			'default' => 'King of Town',
-		),
-		'blog_description' => array(
-			'type' => 'TEXT',
-			'null' => TRUE,
-		),
-	);
-
-
-After the fields have been defined, they can be added using
-``$this->dbforge->add_field($fields);`` followed by a call to the
-``create_table()`` method.
-
-**$this->dbforge->add_field()**
-
-The add fields method will accept the above array.
-
-
-Passing strings as fields
--------------------------
-
-If you know exactly how you want a field to be created, you can pass the
-string into the field definitions with add_field()
-
-::
-
-	$this->dbforge->add_field("label varchar(100) NOT NULL DEFAULT 'default label'");
-
-
-.. note:: Passing raw strings as fields cannot be followed by ``add_key()`` calls on those fields.
-
-.. note:: Multiple calls to add_field() are cumulative.
-
-Creating an id field
---------------------
-
-There is a special exception for creating id fields. A field with type
-id will automatically be assigned as an INT(9) auto_incrementing
-Primary Key.
-
-::
-
-	$this->dbforge->add_field('id');
-	// gives id INT(9) NOT NULL AUTO_INCREMENT
-
-
-Adding Keys
-===========
-
-Generally speaking, you'll want your table to have Keys. This is
-accomplished with $this->dbforge->add_key('field'). An optional second
-parameter set to TRUE will make it a primary key. Note that add_key()
-must be followed by a call to create_table().
-
-Multiple column non-primary keys must be sent as an array. Sample output
-below is for MySQL.
-
-::
-
-	$this->dbforge->add_key('blog_id', TRUE);
-	// gives PRIMARY KEY `blog_id` (`blog_id`)
-
-	$this->dbforge->add_key('blog_id', TRUE);
-	$this->dbforge->add_key('site_id', TRUE);
-	// gives PRIMARY KEY `blog_id_site_id` (`blog_id`, `site_id`)
-
-	$this->dbforge->add_key('blog_name');
-	// gives KEY `blog_name` (`blog_name`)
-
-	$this->dbforge->add_key(array('blog_name', 'blog_label'));
-	// gives KEY `blog_name_blog_label` (`blog_name`, `blog_label`)
-
-
-Creating a table
-================
-
-After fields and keys have been declared, you can create a new table
-with
-
-::
-
-	$this->dbforge->create_table('table_name');
-	// gives CREATE TABLE table_name
-
-
-An optional second parameter set to TRUE adds an "IF NOT EXISTS" clause
-into the definition
-
-::
-
-	$this->dbforge->create_table('table_name', TRUE);
-	// gives CREATE TABLE IF NOT EXISTS table_name
-
-You could also pass optional table attributes, such as MySQL's ``ENGINE``::
-
-	$attributes = array('ENGINE' => 'InnoDB');
-	$this->dbforge->create_table('table_name', FALSE, $attributes);
-	// produces: CREATE TABLE `table_name` (...) ENGINE = InnoDB DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci
-
-.. note:: Unless you specify the ``CHARACTER SET`` and/or ``COLLATE`` attributes,
-	``create_table()`` will always add them with your configured *char_set*
-	and *dbcollat* values, as long as they are not empty (MySQL only).
-
-
-Dropping a table
-================
-
-Execute a DROP TABLE statement and optionally add an IF EXISTS clause.
-
-::
-
-	// Produces: DROP TABLE table_name
-	$this->dbforge->drop_table('table_name');
-
-	// Produces: DROP TABLE IF EXISTS table_name
-	$this->dbforge->drop_table('table_name',TRUE);
-
-
-Renaming a table
-================
-
-Executes a TABLE rename
-
-::
-
-	$this->dbforge->rename_table('old_table_name', 'new_table_name');
-	// gives ALTER TABLE old_table_name RENAME TO new_table_name
-
-
-****************
-Modifying Tables
-****************
-
-Adding a Column to a Table
-==========================
-
-**$this->dbforge->add_column()**
-
-The ``add_column()`` method is used to modify an existing table. It
-accepts the same field array as above, and can be used for an unlimited
-number of additional fields.
-
-::
-
-	$fields = array(
-		'preferences' => array('type' => 'TEXT')
-	);
-	$this->dbforge->add_column('table_name', $fields);
-	// Executes: ALTER TABLE table_name ADD preferences TEXT
-
-If you are using MySQL or CUBIRD, then you can take advantage of their
-AFTER and FIRST clauses to position the new column.
-
-Examples::
-
-	// Will place the new column after the `another_field` column:
-	$fields = array(
-		'preferences' => array('type' => 'TEXT', 'after' => 'another_field')
-	);
-
-	// Will place the new column at the start of the table definition:
-	$fields = array(
-		'preferences' => array('type' => 'TEXT', 'first' => TRUE)
-	);
-
-
-Dropping a Column From a Table
-==============================
-
-**$this->dbforge->drop_column()**
-
-Used to remove a column from a table.
-
-::
-
-	$this->dbforge->drop_column('table_name', 'column_to_drop');
-
-
-
-Modifying a Column in a Table
-=============================
-
-**$this->dbforge->modify_column()**
-
-The usage of this method is identical to ``add_column()``, except it
-alters an existing column rather than adding a new one. In order to
-change the name you can add a "name" key into the field defining array.
-
-::
-
-	$fields = array(
-		'old_name' => array(
-			'name' => 'new_name',
-			'type' => 'TEXT',
-		),
-	);
-	$this->dbforge->modify_column('table_name', $fields);
-	// gives ALTER TABLE table_name CHANGE old_name new_name TEXT

-####################
-Query Helper Methods
-####################
-
-Information From Executing a Query
-==================================
-
-**$this->db->insert_id()**
-
-The insert ID number when performing database inserts.
-
-.. note:: If using the PDO driver with PostgreSQL, or using the Interbase
-	driver, this function requires a $name parameter, which specifies the 
-	appropriate sequence to check for the insert id.
-
-**$this->db->affected_rows()**
-
-Displays the number of affected rows, when doing "write" type queries
-(insert, update, etc.).
-
-.. note:: In MySQL "DELETE FROM TABLE" returns 0 affected rows. The database
-	class has a small hack that allows it to return the correct number of
-	affected rows. By default this hack is enabled but it can be turned off
-	in the database driver file.
-
-**$this->db->last_query()**
-
-Returns the last query that was run (the query string, not the result).
-Example::
-
-	$str = $this->db->last_query();
-	
-	// Produces:  SELECT * FROM sometable....
-
-
-.. note:: Disabling the **save_queries** setting in your database
-	configuration will render this function useless.
-
-Information About Your Database
-===============================
-
-**$this->db->count_all()**
-
-Permits you to determine the number of rows in a particular table.
-Submit the table name in the first parameter. Example::
-
-	echo $this->db->count_all('my_table');
-	
-	// Produces an integer, like 25
-
-**$this->db->platform()**
-
-Outputs the database platform you are running (MySQL, MS SQL, Postgres,
-etc...)::
-
-	echo $this->db->platform();
-
-**$this->db->version()**
-
-Outputs the database version you are running::
-
-	echo $this->db->version();
-
-Making Your Queries Easier
-==========================
-
-**$this->db->insert_string()**
-
-This function simplifies the process of writing database inserts. It
-returns a correctly formatted SQL insert string. Example::
-
-	$data = array('name' => $name, 'email' => $email, 'url' => $url);
-	
-	$str = $this->db->insert_string('table_name', $data);
-
-The first parameter is the table name, the second is an associative
-array with the data to be inserted. The above example produces::
-
-	INSERT INTO table_name (name, email, url) VALUES ('Rick', 'rick@example.com', 'example.com')
-
-.. note:: Values are automatically escaped, producing safer queries.
-
-**$this->db->update_string()**
-
-This function simplifies the process of writing database updates. It
-returns a correctly formatted SQL update string. Example::
-
-	$data = array('name' => $name, 'email' => $email, 'url' => $url);
-	
-	$where = "author_id = 1 AND status = 'active'";
-	
-	$str = $this->db->update_string('table_name', $data, $where);
-
-The first parameter is the table name, the second is an associative
-array with the data to be updated, and the third parameter is the
-"where" clause. The above example produces::
-
-	 UPDATE table_name SET name = 'Rick', email = 'rick@example.com', url = 'example.com' WHERE author_id = 1 AND status = 'active'
-
-.. note:: Values are automatically escaped, producing safer queries.

-#################
-Database Metadata
-#################
-
-**************
-Table MetaData
-**************
-
-These functions let you fetch table information.
-
-List the Tables in Your Database
-================================
-
-**$this->db->list_tables();**
-
-Returns an array containing the names of all the tables in the database
-you are currently connected to. Example::
-
-	$tables = $this->db->list_tables();
-	
-	foreach ($tables as $table)
-	{
-		echo $table;
-	}
-
-
-Determine If a Table Exists
-===========================
-
-**$this->db->table_exists();**
-
-Sometimes it's helpful to know whether a particular table exists before
-running an operation on it. Returns a boolean TRUE/FALSE. Usage example::
-
-	if ($this->db->table_exists('table_name'))
-	{
-		// some code...
-	}
-
-.. note:: Replace *table_name* with the name of the table you are looking for.
-
-
-**************
-Field MetaData
-**************
-
-List the Fields in a Table
-==========================
-
-**$this->db->list_fields()**
-
-Returns an array containing the field names. This query can be called
-two ways:
-
-1. You can supply the table name and call it from the $this->db->
-object::
-
-	$fields = $this->db->list_fields('table_name');
-	
-	foreach ($fields as $field)
-	{
-		echo $field;
-	}
-
-2. You can gather the field names associated with any query you run by
-calling the function from your query result object::
-
-	$query = $this->db->query('SELECT * FROM some_table');
-	
-	foreach ($query->list_fields() as $field)
-	{
-		echo $field;
-	}
-
-
-Determine If a Field is Present in a Table
-==========================================
-
-**$this->db->field_exists()**
-
-Sometimes it's helpful to know whether a particular field exists before
-performing an action. Returns a boolean TRUE/FALSE. Usage example::
-
-	if ($this->db->field_exists('field_name', 'table_name'))
-	{
-		// some code...
-	}
-
-.. note:: Replace *field_name* with the name of the column you are looking
-	for, and replace *table_name* with the name of the table you are
-	looking for.
-
-
-Retrieve Field Metadata
-=======================
-
-**$this->db->field_data()**
-
-Returns an array of objects containing field information.
-
-Sometimes it's helpful to gather the field names or other metadata, like
-the column type, max length, etc.
-
-.. note:: Not all databases provide meta-data.
-
-Usage example::
-
-	$fields = $this->db->field_data('table_name');
-	
-	foreach ($fields as $field)
-	{
-		echo $field->name;
-		echo $field->type;
-		echo $field->max_length;
-		echo $field->primary_key;
-	}
-
-If you have run a query already you can use the result object instead of
-supplying the table name::
-
-	$query = $this->db->query("YOUR QUERY");
-	$fields = $query->field_data();
-
-The following data is available from this function if supported by your
-database:
-
--  name - column name
--  max_length - maximum length of the column
--  primary_key - 1 if the column is a primary key
--  type - the type of the column

-Queries
-#######
-
-************
-Query Basics
-************
-
-Regular Queries
-===============
-
-To submit a query, use the **query** function::
-
-	$this->db->query('YOUR QUERY HERE');
-
-The query() function returns a database result **object** when "read"
-type queries are run, which you can use to :doc:`show your
-results <results>`. When "write" type queries are run it simply
-returns TRUE or FALSE depending on success or failure. When retrieving
-data you will typically assign the query to your own variable, like
-this::
-
-	$query = $this->db->query('YOUR QUERY HERE');
-
-Simplified Queries
-==================
-
-The **simple_query** method is a simplified version of the 
-$this->db->query() method. It DOES
-NOT return a database result set, nor does it set the query timer, or
-compile bind data, or store your query for debugging. It simply lets you
-submit a query. Most users will rarely use this function.
-
-It returns whatever the database drivers' "execute" function returns.
-That typically is TRUE/FALSE on success or failure for write type queries
-such as INSERT, DELETE or UPDATE statements (which is what it really
-should be used for) and a resource/object on success for queries with
-fetchable results.
-
-::
-
-	if ($this->db->simple_query('YOUR QUERY'))
-	{
-		echo "Success!";
-	}
-	else
-	{
-		echo "Query failed!";
-	}
-
-.. note:: PostgreSQL's ``pg_exec()`` function (for example) always
-	returns a resource on success, even for write type queries.
-	So take that in mind if you're looking for a boolean value.
-
-***************************************
-Working with Database prefixes manually
-***************************************
-
-If you have configured a database prefix and would like to prepend it to
-a table name for use in a native SQL query for example, then you can use
-the following::
-
-	$this->db->dbprefix('tablename'); // outputs prefix_tablename
-
-
-If for any reason you would like to change the prefix programatically
-without needing to create a new connection, you can use this method::
-
-	$this->db->set_dbprefix('newprefix');
-	$this->db->dbprefix('tablename'); // outputs newprefix_tablename
-
-
-**********************
-Protecting identifiers
-**********************
-
-In many databases it is advisable to protect table and field names - for
-example with backticks in MySQL. **Query Builder queries are
-automatically protected**, however if you need to manually protect an
-identifier you can use::
-
-	$this->db->protect_identifiers('table_name');
-
-.. important:: Although the Query Builder will try its best to properly
-	quote any field and table names that you feed it, note that it
-	is NOT designed to work with arbitrary user input. DO NOT feed it
-	with unsanitized user data.
-
-This function will also add a table prefix to your table, assuming you
-have a prefix specified in your database config file. To enable the
-prefixing set TRUE (boolean) via the second parameter::
-
-	$this->db->protect_identifiers('table_name', TRUE);
-
-
-****************
-Escaping Queries
-****************
-
-It's a very good security practice to escape your data before submitting
-it into your database. CodeIgniter has three methods that help you do
-this:
-
-#. **$this->db->escape()** This function determines the data type so
-   that it can escape only string data. It also automatically adds
-   single quotes around the data so you don't have to:
-   ::
-
-	$sql = "INSERT INTO table (title) VALUES(".$this->db->escape($title).")";
-
-#. **$this->db->escape_str()** This function escapes the data passed to
-   it, regardless of type. Most of the time you'll use the above
-   function rather than this one. Use the function like this:
-   ::
-
-	$sql = "INSERT INTO table (title) VALUES('".$this->db->escape_str($title)."')";
-
-#. **$this->db->escape_like_str()** This method should be used when
-   strings are to be used in LIKE conditions so that LIKE wildcards
-   ('%', '\_') in the string are also properly escaped.
-
-::
-
-        $search = '20% raise'; 
-        $sql = "SELECT id FROM table WHERE column LIKE '%" .
-            $this->db->escape_like_str($search)."%' ESCAPE '!'";
-
-.. important:: The ``escape_like_str()`` method uses '!' (exclamation mark)
-	to escape special characters for *LIKE* conditions. Because this
-	method escapes partial strings that you would wrap in quotes
-	yourself, it cannot automatically add the ``ESCAPE '!'``
-	condition for you, and so you'll have to manually do that.
-
-
-**************
-Query Bindings
-**************
-
-Bindings enable you to simplify your query syntax by letting the system
-put the queries together for you. Consider the following example::
-
-	$sql = "SELECT * FROM some_table WHERE id = ? AND status = ? AND author = ?";
-	$this->db->query($sql, array(3, 'live', 'Rick'));
-
-The question marks in the query are automatically replaced with the
-values in the array in the second parameter of the query function.
-
-Binding also work with arrays, which will be transformed to IN sets::
-
-	$sql = "SELECT * FROM some_table WHERE id IN ? AND status = ? AND author = ?";
-	$this->db->query($sql, array(array(3, 6), 'live', 'Rick'));
-
-The resulting query will be::
-
-	SELECT * FROM some_table WHERE id IN (3,6) AND status = 'live' AND author = 'Rick'
-
-The secondary benefit of using binds is that the values are
-automatically escaped, producing safer queries. You don't have to
-remember to manually escape data; the engine does it automatically for
-you.
-
-***************
-Handling Errors
-***************
-
-**$this->db->error();**
-
-If you need to get the last error that has occurred, the error() method
-will return an array containing its code and message. Here's a quick
-example::
-
-	if ( ! $this->db->simple_query('SELECT `example_field` FROM `example_table`'))
-	{
-		$error = $this->db->error(); // Has keys 'code' and 'message'
-	}

-###################
-Query Builder Class
-###################
-
-CodeIgniter gives you access to a Query Builder class. This pattern
-allows information to be retrieved, inserted, and updated in your
-database with minimal scripting. In some cases only one or two lines
-of code are necessary to perform a database action.
-CodeIgniter does not require that each database table be its own class
-file. It instead provides a more simplified interface.
-
-Beyond simplicity, a major benefit to using the Query Builder features
-is that it allows you to create database independent applications, since
-the query syntax is generated by each database adapter. It also allows
-for safer queries, since the values are escaped automatically by the
-system.
-
-.. note:: If you intend to write your own queries you can disable this
-	class in your database config file, allowing the core database library
-	and adapter to utilize fewer resources.
-
-.. contents::
-    :local:
-    :depth: 1
-
-**************
-Selecting Data
-**************
-
-The following functions allow you to build SQL **SELECT** statements.
-
-**$this->db->get()**
-
-Runs the selection query and returns the result. Can be used by itself
-to retrieve all records from a table::
-
-	$query = $this->db->get('mytable');  // Produces: SELECT * FROM mytable
-
-The second and third parameters enable you to set a limit and offset
-clause::
-
-	$query = $this->db->get('mytable', 10, 20);
-
-	// Executes: SELECT * FROM mytable LIMIT 20, 10
-	// (in MySQL. Other databases have slightly different syntax)
-
-You'll notice that the above function is assigned to a variable named
-$query, which can be used to show the results::
-
-	$query = $this->db->get('mytable');
-
-	foreach ($query->result() as $row)
-	{
-		echo $row->title;
-	}
-
-Please visit the :doc:`result functions <results>` page for a full
-discussion regarding result generation.
-
-**$this->db->get_compiled_select()**
-
-Compiles the selection query just like **$this->db->get()** but does not *run*
-the query. This method simply returns the SQL query as a string.
-
-Example::
-
-	$sql = $this->db->get_compiled_select('mytable');
-	echo $sql;
-
-	// Prints string: SELECT * FROM mytable
-
-The second parameter enables you to set whether or not the query builder query
-will be reset (by default it will be reset, just like when using `$this->db->get()`)::
-
-	echo $this->db->limit(10,20)->get_compiled_select('mytable', FALSE);
-
-	// Prints string: SELECT * FROM mytable LIMIT 20, 10
-	// (in MySQL. Other databases have slightly different syntax)
-
-	echo $this->db->select('title, content, date')->get_compiled_select();
-
-	// Prints string: SELECT title, content, date FROM mytable LIMIT 20, 10
-
-The key thing to notice in the above example is that the second query did not
-utilize **$this->db->from()** and did not pass a table name into the first
-parameter. The reason for this outcome is because the query has not been
-executed using **$this->db->get()** which resets values or reset directly
-using **$this->db->reset_query()**.
-
-**$this->db->get_where()**
-
-Identical to the above function except that it permits you to add a
-"where" clause in the second parameter, instead of using the db->where()
-function::
-
-	$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);
-
-Please read the about the where function below for more information.
-
-.. note:: get_where() was formerly known as getwhere(), which has been removed
-
-**$this->db->select()**
-
-Permits you to write the SELECT portion of your query::
-
-	$this->db->select('title, content, date');
-	$query = $this->db->get('mytable');
-
-	// Executes: SELECT title, content, date FROM mytable
-
-.. note:: If you are selecting all (\*) from a table you do not need to
-	use this function. When omitted, CodeIgniter assumes that you wish
-	to select all fields and automatically adds 'SELECT \*'.
-
-``$this->db->select()`` accepts an optional second parameter. If you set it
-to FALSE, CodeIgniter will not try to protect your field or table names.
-This is useful if you need a compound select statement where automatic
-escaping of fields may break them.
-
-::
-
-	$this->db->select('(SELECT SUM(payments.amount) FROM payments WHERE payments.invoice_id=4') AS amount_paid', FALSE);
-	$query = $this->db->get('mytable');
-
-**$this->db->select_max()**
-
-Writes a ``SELECT MAX(field)`` portion for your query. You can optionally
-include a second parameter to rename the resulting field.
-
-::
-
-	$this->db->select_max('age');
-	$query = $this->db->get('members');  // Produces: SELECT MAX(age) as age FROM members
-
-	$this->db->select_max('age', 'member_age');
-	$query = $this->db->get('members'); // Produces: SELECT MAX(age) as member_age FROM members
-
-
-**$this->db->select_min()**
-
-Writes a "SELECT MIN(field)" portion for your query. As with
-select_max(), You can optionally include a second parameter to rename
-the resulting field.
-
-::
-
-	$this->db->select_min('age');
-	$query = $this->db->get('members'); // Produces: SELECT MIN(age) as age FROM members
-
-
-**$this->db->select_avg()**
-
-Writes a "SELECT AVG(field)" portion for your query. As with
-select_max(), You can optionally include a second parameter to rename
-the resulting field.
-
-::
-
-	$this->db->select_avg('age');
-	$query = $this->db->get('members'); // Produces: SELECT AVG(age) as age FROM members
-
-
-**$this->db->select_sum()**
-
-Writes a "SELECT SUM(field)" portion for your query. As with
-select_max(), You can optionally include a second parameter to rename
-the resulting field.
-
-::
-
-	$this->db->select_sum('age');
-	$query = $this->db->get('members'); // Produces: SELECT SUM(age) as age FROM members
-
-**$this->db->from()**
-
-Permits you to write the FROM portion of your query::
-
-	$this->db->select('title, content, date');
-	$this->db->from('mytable');
-	$query = $this->db->get();  // Produces: SELECT title, content, date FROM mytable
-
-.. note:: As shown earlier, the FROM portion of your query can be specified
-	in the $this->db->get() function, so use whichever method you prefer.
-
-**$this->db->join()**
-
-Permits you to write the JOIN portion of your query::
-
-	$this->db->select('*');
-	$this->db->from('blogs');
-	$this->db->join('comments', 'comments.id = blogs.id');
-	$query = $this->db->get();
-
-	// Produces:
-	// SELECT * FROM blogs JOIN comments ON comments.id = blogs.id
-
-Multiple function calls can be made if you need several joins in one
-query.
-
-If you need a specific type of JOIN you can specify it via the third
-parameter of the function. Options are: left, right, outer, inner, left
-outer, and right outer.
-
-::
-
-	$this->db->join('comments', 'comments.id = blogs.id', 'left');
-	// Produces: LEFT JOIN comments ON comments.id = blogs.id

-
-**$this->db->where()**
-
-This function enables you to set **WHERE** clauses using one of four
-methods:
-
-.. note:: All values passed to this function are escaped automatically,
-	producing safer queries.
-
-#. **Simple key/value method:**
-
-	::
-
-		$this->db->where('name', $name); // Produces: WHERE name = 'Joe'
-
-	Notice that the equal sign is added for you.
-
-	If you use multiple function calls they will be chained together with
-	AND between them:
-
-	::
-
-		$this->db->where('name', $name);
-		$this->db->where('title', $title);
-		$this->db->where('status', $status);
-		// WHERE name = 'Joe' AND title = 'boss' AND status = 'active'
-
-#. **Custom key/value method:**
-
-	You can include an operator in the first parameter in order to
-	control the comparison:
-
-	::
-
-		$this->db->where('name !=', $name);
-		$this->db->where('id <', $id); // Produces: WHERE name != 'Joe' AND id < 45
-
-#. **Associative array method:**
-
-	::
-
-		$array = array('name' => $name, 'title' => $title, 'status' => $status);
-		$this->db->where($array);
-		// Produces: WHERE name = 'Joe' AND title = 'boss' AND status = 'active'
-
-	You can include your own operators using this method as well:
-
-	::
-
-		$array = array('name !=' => $name, 'id <' => $id, 'date >' => $date);
-		$this->db->where($array);
-
-#. **Custom string:**
-	You can write your own clauses manually::
-
-		$where = "name='Joe' AND status='boss' OR status='active'";
-		$this->db->where($where);
-
-
-``$this->db->where()`` accepts an optional third parameter. If you set it to
-FALSE, CodeIgniter will not try to protect your field or table names.
-
-::
-
-	$this->db->where('MATCH (field) AGAINST ("value")', NULL, FALSE);
-
-**$this->db->or_where()**
-
-This function is identical to the one above, except that multiple
-instances are joined by OR::
-
-	$this->db->where('name !=', $name);
-	$this->db->or_where('id >', $id);  // Produces: WHERE name != 'Joe' OR id > 50
-
-.. note:: or_where() was formerly known as orwhere(), which has been
-	removed.
-
-**$this->db->where_in()**
-
-Generates a WHERE field IN ('item', 'item') SQL query joined with AND if
-appropriate
-
-::
-
-	$names = array('Frank', 'Todd', 'James');
-	$this->db->where_in('username', $names);
-	// Produces: WHERE username IN ('Frank', 'Todd', 'James')
-
-
-**$this->db->or_where_in()**
-
-Generates a WHERE field IN ('item', 'item') SQL query joined with OR if
-appropriate
-
-::
-
-	$names = array('Frank', 'Todd', 'James');
-	$this->db->or_where_in('username', $names);
-	// Produces: OR username IN ('Frank', 'Todd', 'James')
-
-**$this->db->where_not_in()**
-
-Generates a WHERE field NOT IN ('item', 'item') SQL query joined with
-AND if appropriate
-
-::
-
-	$names = array('Frank', 'Todd', 'James');
-	$this->db->where_not_in('username', $names);
-	// Produces: WHERE username NOT IN ('Frank', 'Todd', 'James')
-
-
-**$this->db->or_where_not_in()**
-
-Generates a WHERE field NOT IN ('item', 'item') SQL query joined with OR
-if appropriate
-
-::
-
-	$names = array('Frank', 'Todd', 'James');
-	$this->db->or_where_not_in('username', $names);
-	// Produces: OR username NOT IN ('Frank', 'Todd', 'James')

-************************
-Looking for Similar Data
-************************
-
-**$this->db->like()**
-
-This method enables you to generate **LIKE** clauses, useful for doing
-searches.
-
-.. note:: All values passed to this method are escaped automatically.
-
-#. **Simple key/value method:**
-
-	::
-
-		$this->db->like('title', 'match');
-		// Produces: WHERE `title` LIKE '%match%' ESCAPE '!'
-
-	If you use multiple method calls they will be chained together with
-	AND between them::
-
-		$this->db->like('title', 'match');
-		$this->db->like('body', 'match');
-		// WHERE `title` LIKE '%match%' ESCAPE '!' AND  `body` LIKE '%match% ESCAPE '!'
-
-	If you want to control where the wildcard (%) is placed, you can use
-	an optional third argument. Your options are 'before', 'after' and
-	'both' (which is the default).
-
-	::
-
-		$this->db->like('title', 'match', 'before');	// Produces: WHERE `title` LIKE '%match' ESCAPE '!'
-		$this->db->like('title', 'match', 'after');	// Produces: WHERE `title` LIKE 'match%' ESCAPE '!'
-		$this->db->like('title', 'match', 'both');	// Produces: WHERE `title` LIKE '%match%' ESCAPE '!'
-
-#. **Associative array method:**
-
-	::
-
-		$array = array('title' => $match, 'page1' => $match, 'page2' => $match);
-		$this->db->like($array);
-		// WHERE `title` LIKE '%match%' ESCAPE '!' AND  `page1` LIKE '%match%' ESCAPE '!' AND  `page2` LIKE '%match%' ESCAPE '!'
-
-
-**$this->db->or_like()**
-
-This method is identical to the one above, except that multiple
-instances are joined by OR::
-
-	$this->db->like('title', 'match'); $this->db->or_like('body', $match);
-	// WHERE `title` LIKE '%match%' ESCAPE '!' OR  `body` LIKE '%match%' ESCAPE '!'
-
-.. note:: ``or_like()`` was formerly known as ``orlike()``, which has been removed.
-
-**$this->db->not_like()**
-
-This method is identical to ``like()``, except that it generates
-NOT LIKE statements::
-
-	$this->db->not_like('title', 'match');	// WHERE `title` NOT LIKE '%match% ESCAPE '!'
-
-**$this->db->or_not_like()**
-
-This method is identical to ``not_like()``, except that multiple
-instances are joined by OR::
-
-	$this->db->like('title', 'match');
-	$this->db->or_not_like('body', 'match');
-	// WHERE `title` LIKE '%match% OR  `body` NOT LIKE '%match%' ESCAPE '!'
-
-**$this->db->group_by()**
-
-Permits you to write the GROUP BY portion of your query::
-
-	$this->db->group_by("title"); // Produces: GROUP BY title
-
-You can also pass an array of multiple values as well::
-
-	$this->db->group_by(array("title", "date"));  // Produces: GROUP BY title, date
-
-.. note:: group_by() was formerly known as groupby(), which has been
-	removed.
-
-**$this->db->distinct()**
-
-Adds the "DISTINCT" keyword to a query
-
-::
-
-	$this->db->distinct();
-	$this->db->get('table'); // Produces: SELECT DISTINCT * FROM table
-
-**$this->db->having()**
-
-Permits you to write the HAVING portion of your query. There are 2
-possible syntaxes, 1 argument or 2::
-
-	$this->db->having('user_id = 45');  // Produces: HAVING user_id = 45
-	$this->db->having('user_id',  45);  // Produces: HAVING user_id = 45
-
-You can also pass an array of multiple values as well::
-
-	$this->db->having(array('title =' => 'My Title', 'id <' => $id));
-	// Produces: HAVING title = 'My Title', id < 45
-
-
-If you are using a database that CodeIgniter escapes queries for, you
-can prevent escaping content by passing an optional third argument, and
-setting it to FALSE.
-
-::
-
-	$this->db->having('user_id',  45);  // Produces: HAVING `user_id` = 45 in some databases such as MySQL
-	$this->db->having('user_id',  45, FALSE);  // Produces: HAVING user_id = 45
-
-
-**$this->db->or_having()**
-
-Identical to having(), only separates multiple clauses with "OR".
-
-****************
-Ordering results
-****************
-
-**$this->db->order_by()**
-
-Lets you set an ORDER BY clause.
-
-The first parameter contains the name of the column you would like to order by.
-
-The second parameter lets you set the direction of the result.
-Options are **ASC**, **DESC** AND **RANDOM**.
-
-::
-
-	$this->db->order_by('title', 'DESC');
-	// Produces: ORDER BY `title` DESC
-
-You can also pass your own string in the first parameter::
-
-	$this->db->order_by('title DESC, name ASC');
-	// Produces: ORDER BY `title` DESC, `name` ASC
-
-Or multiple function calls can be made if you need multiple fields.
-
-::
-
-	$this->db->order_by('title', 'DESC');
-	$this->db->order_by('name', 'ASC');
-	// Produces: ORDER BY `title` DESC, `name` ASC
-
-If you choose the **RANDOM** direction option, then the first parameters will
-be ignored, unless you specify a numeric seed value.
-
-::
-
-	$this->db->order_by('title', 'RANDOM');
-	// Produces: ORDER BY RAND()
-
-	$this->db->order_by(42, 'RANDOM');
-	// Produces: ORDER BY RAND(42)
-
-.. note:: order_by() was formerly known as orderby(), which has been
-	removed.
-
-.. note:: Random ordering is not currently supported in Oracle and
-	will default to ASC instead.
-
-****************************
-Limiting or Counting Results
-****************************
-
-**$this->db->limit()**
-
-Lets you limit the number of rows you would like returned by the query::
-
-	$this->db->limit(10);  // Produces: LIMIT 10
-
-The second parameter lets you set a result offset.
-
-::
-
-	$this->db->limit(10, 20);  // Produces: LIMIT 20, 10 (in MySQL.  Other databases have slightly different syntax)
-
-**$this->db->count_all_results()**
-
-Permits you to determine the number of rows in a particular Active
-Record query. Queries will accept Query Builder restrictors such as
-``where()``, ``or_where()``, ``like()``, ``or_like()``, etc. Example::
-
-	echo $this->db->count_all_results('my_table');  // Produces an integer, like 25
-	$this->db->like('title', 'match');
-	$this->db->from('my_table');
-	echo $this->db->count_all_results(); // Produces an integer, like 17
-
-However, this method also resets any field values that you may have passed
-to ``select()``. If you need to keep them, you can pass ``FALSE`` as the
-second parameter::
-
-	echo $this->db->count_all_results('my_table', FALSE);
-
-**$this->db->count_all()**
-
-Permits you to determine the number of rows in a particular table.
-Submit the table name in the first parameter. Example::
-
-	echo $this->db->count_all('my_table');  // Produces an integer, like 25
-
-**************
-Query grouping
-**************
-
-Query grouping allows you to create groups of WHERE clauses by enclosing them in parentheses. This will allow
-you to create queries with complex WHERE clauses. Nested groups are supported. Example::
-
-	$this->db->select('*')->from('my_table')
-		->group_start()
-			->where('a', 'a')
-			->or_group_start()
-				->where('b', 'b')
-				->where('c', 'c')
-			->group_end()
-		->group_end()
-		->where('d', 'd')
-	->get();
-
-	// Generates:
-	// SELECT * FROM (`my_table`) WHERE ( `a` = 'a' OR ( `b` = 'b' AND `c` = 'c' ) ) AND `d` = 'd'
-
-.. note:: groups need to be balanced, make sure every group_start() is matched by a group_end().
-
-**$this->db->group_start()**
-
-Starts a new group by adding an opening parenthesis to the WHERE clause of the query.
-
-**$this->db->or_group_start()**
-
-Starts a new group by adding an opening parenthesis to the WHERE clause of the query, prefixing it with 'OR'.
-
-**$this->db->not_group_start()**
-
-Starts a new group by adding an opening parenthesis to the WHERE clause of the query, prefixing it with 'NOT'.
-
-**$this->db->or_not_group_start()**
-
-Starts a new group by adding an opening parenthesis to the WHERE clause of the query, prefixing it with 'OR NOT'.
-
-**$this->db->group_end()**
-
-Ends the current group by adding an closing parenthesis to the WHERE clause of the query.
-
-**************
-Inserting Data
-**************
-
-**$this->db->insert()**
-
-Generates an insert string based on the data you supply, and runs the
-query. You can either pass an **array** or an **object** to the
-function. Here is an example using an array::
-
-	$data = array(
-		'title' => 'My title',
-		'name' => 'My Name',
-		'date' => 'My date'
-	);
-
-	$this->db->insert('mytable', $data);
-	// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
-
-The first parameter will contain the table name, the second is an
-associative array of values.
-
-Here is an example using an object::
-
-	/*
-	class Myclass {
-		public $title = 'My Title';
-		public $content = 'My Content';
-		public $date = 'My Date';
-	}
-	*/
-
-	$object = new Myclass;
-	$this->db->insert('mytable', $object);
-	// Produces: INSERT INTO mytable (title, content, date) VALUES ('My Title', 'My Content', 'My Date')
-
-The first parameter will contain the table name, the second is an
-object.
-
-.. note:: All values are escaped automatically producing safer queries.
-
-**$this->db->get_compiled_insert()**
-
-Compiles the insertion query just like $this->db->insert() but does not
-*run* the query. This method simply returns the SQL query as a string.
-
-Example::
-
-	$data = array(
-		'title' => 'My title',
-		'name'  => 'My Name',
-		'date'  => 'My date'
-	);
-
-	$sql = $this->db->set($data)->get_compiled_insert('mytable');
-	echo $sql;
-
-	// Produces string: INSERT INTO mytable (`title`, `name`, `date`) VALUES ('My title', 'My name', 'My date')
-
-The second parameter enables you to set whether or not the query builder query
-will be reset (by default it will be--just like $this->db->insert())::
-
-	echo $this->db->set('title', 'My Title')->get_compiled_insert('mytable', FALSE);
-
-	// Produces string: INSERT INTO mytable (`title`) VALUES ('My Title')
-
-	echo $this->db->set('content', 'My Content')->get_compiled_insert();
-
-	// Produces string: INSERT INTO mytable (`title`, `content`) VALUES ('My Title', 'My Content')
-
-The key thing to notice in the above example is that the second query did not
-utlize `$this->db->from()` nor did it pass a table name into the first
-parameter. The reason this worked is because the query has not been executed
-using `$this->db->insert()` which resets values or reset directly using
-`$this->db->reset_query()`.
-
-.. note:: This method doesn't work for batched inserts.
-
-**$this->db->insert_batch()**
-
-Generates an insert string based on the data you supply, and runs the
-query. You can either pass an **array** or an **object** to the
-function. Here is an example using an array::
-
-	$data = array(
-		array(
-			'title' => 'My title',
-			'name' => 'My Name',
-			'date' => 'My date'
-		),
-		array(
-			'title' => 'Another title',
-			'name' => 'Another Name',
-			'date' => 'Another date'
-		)
-	);
-
-	$this->db->insert_batch('mytable', $data);
-	// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'),  ('Another title', 'Another name', 'Another date')
-
-The first parameter will contain the table name, the second is an
-associative array of values.
-
-.. note:: All values are escaped automatically producing safer queries.
-
-*************
-Updating Data
-*************
-
-**$this->db->replace()**
-
-This method executes a REPLACE statement, which is basically the SQL
-standard for (optional) DELETE + INSERT, using *PRIMARY* and *UNIQUE*
-keys as the determining factor.
-In our case, it will save you from the need to implement complex
-logics with different combinations of  ``select()``, ``update()``,
-``delete()`` and ``insert()`` calls.
-
-Example::
-
-	$data = array(
-		'title' => 'My title',
-		'name'  => 'My Name',
-		'date'  => 'My date'
-	);
-
-	$this->db->replace('table', $data);
-
-	// Executes: REPLACE INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date')
-
-In the above example, if we assume that the *title* field is our primary
-key, then if a row containing 'My title' as the *title* value, that row
-will be deleted with our new row data replacing it.
-
-Usage of the ``set()`` method is also allowed and all fields are
-automatically escaped, just like with ``insert()``.
-
-**$this->db->set()**
-
-This function enables you to set values for inserts or updates.
-
-**It can be used instead of passing a data array directly to the insert
-or update functions:**
-
-::
-
-	$this->db->set('name', $name);
-	$this->db->insert('mytable');  // Produces: INSERT INTO mytable (`name`) VALUES ('{$name}')
-
-If you use multiple function called they will be assembled properly
-based on whether you are doing an insert or an update::
-
-	$this->db->set('name', $name);
-	$this->db->set('title', $title);
-	$this->db->set('status', $status);
-	$this->db->insert('mytable');
-
-**set()** will also accept an optional third parameter (``$escape``), that
-will prevent data from being escaped if set to FALSE. To illustrate the
-difference, here is ``set()`` used both with and without the escape
-parameter.
-
-::
-
-	$this->db->set('field', 'field+1', FALSE);
-	$this->db->where('id', 2);
-	$this->db->update('mytable'); // gives UPDATE mytable SET field = field+1 WHERE id = 2
-
-	$this->db->set('field', 'field+1');
-	$this->db->where('id', 2);
-	$this->db->update('mytable'); // gives UPDATE `mytable` SET `field` = 'field+1' WHERE `id` = 2
-
-You can also pass an associative array to this function::
-
-	$array = array(
-		'name' => $name,
-		'title' => $title,
-		'status' => $status
-	);
-
-	$this->db->set($array);
-	$this->db->insert('mytable');
-
-Or an object::
-
-	/*
-	class Myclass {
-		public $title = 'My Title';
-		public $content = 'My Content';
-		public $date = 'My Date';
-	}
-	*/
-
-	$object = new Myclass;
-	$this->db->set($object);
-	$this->db->insert('mytable');
-
-**$this->db->update()**
-
-Generates an update string and runs the query based on the data you
-supply. You can pass an **array** or an **object** to the function. Here
-is an example using an array::
-
-	$data = array(
-		'title' => $title,
-		'name' => $name,
-		'date' => $date
-	);
-
-	$this->db->where('id', $id);
-	$this->db->update('mytable', $data);
-	// Produces:
-	//
-	//	UPDATE mytable
-	//	SET title = '{$title}', name = '{$name}', date = '{$date}'
-	//	WHERE id = $id
-
-Or you can supply an object::
-
-	/*
-	class Myclass {
-		public $title = 'My Title';
-		public $content = 'My Content';
-		public $date = 'My Date';
-	}
-	*/
-
-	$object = new Myclass;
-	$this->db->where('id', $id);
-	$this->db->update('mytable', $object);
-	// Produces:
-	//
-	// UPDATE `mytable`
-	// SET `title` = '{$title}', `name` = '{$name}', `date` = '{$date}'
-	// WHERE id = `$id`
-
-.. note:: All values are escaped automatically producing safer queries.
-
-You'll notice the use of the $this->db->where() function, enabling you
-to set the WHERE clause. You can optionally pass this information
-directly into the update function as a string::
-
-	$this->db->update('mytable', $data, "id = 4");
-
-Or as an array::
-
-	$this->db->update('mytable', $data, array('id' => $id));
-
-You may also use the $this->db->set() function described above when
-performing updates.
-
-**$this->db->update_batch()**
-
-Generates an update string based on the data you supply, and runs the query.
-You can either pass an **array** or an **object** to the function.
-Here is an example using an array::
-
-	$data = array(
-	   array(
-	      'title' => 'My title' ,
-	      'name' => 'My Name 2' ,
-	      'date' => 'My date 2'
-	   ),
-	   array(
-	      'title' => 'Another title' ,
-	      'name' => 'Another Name 2' ,
-	      'date' => 'Another date 2'
-	   )
-	);
-
-	$this->db->update_batch('mytable', $data, 'title');
-
-	// Produces:
-	// UPDATE `mytable` SET `name` = CASE
-	// WHEN `title` = 'My title' THEN 'My Name 2'
-	// WHEN `title` = 'Another title' THEN 'Another Name 2'
-	// ELSE `name` END,
-	// `date` = CASE
-	// WHEN `title` = 'My title' THEN 'My date 2'
-	// WHEN `title` = 'Another title' THEN 'Another date 2'
-	// ELSE `date` END
-	// WHERE `title` IN ('My title','Another title')
-
-The first parameter will contain the table name, the second is an associative
-array of values, the third parameter is the where key.
-
-.. note:: All values are escaped automatically producing safer queries.
-
-.. note:: ``affected_rows()`` won't give you proper results with this method,
-	due to the very nature of how it works. Instead, ``update_batch()``
-	returns the number of rows affected.
-
-**$this->db->get_compiled_update()**
-
-This works exactly the same way as ``$this->db->get_compiled_insert()`` except
-that it produces an UPDATE SQL string instead of an INSERT SQL string.
-
-For more information view documentation for `$this->db->get_compiled_insert()`.
-
-.. note:: This method doesn't work for batched updates.
-
-*************
-Deleting Data
-*************
-
-**$this->db->delete()**
-
-Generates a delete SQL string and runs the query.
-
-::
-
-	$this->db->delete('mytable', array('id' => $id));  // Produces: // DELETE FROM mytable  // WHERE id = $id
-
-The first parameter is the table name, the second is the where clause.
-You can also use the where() or or_where() functions instead of passing
-the data to the second parameter of the function::
-
-	$this->db->where('id', $id);
-	$this->db->delete('mytable');
-
-	// Produces:
-	// DELETE FROM mytable
-	// WHERE id = $id
-
-
-An array of table names can be passed into delete() if you would like to
-delete data from more than 1 table.
-
-::
-
-	$tables = array('table1', 'table2', 'table3');
-	$this->db->where('id', '5');
-	$this->db->delete($tables);
-
-
-If you want to delete all data from a table, you can use the truncate()
-function, or empty_table().
-
-**$this->db->empty_table()**
-
-Generates a delete SQL string and runs the
-query.::
-
-	  $this->db->empty_table('mytable'); // Produces: DELETE FROM mytable
-
-**$this->db->truncate()**
-
-Generates a truncate SQL string and runs the query.
-
-::
-
-	$this->db->from('mytable');
-	$this->db->truncate();
-
-	// or
-
-	$this->db->truncate('mytable');
-
-	// Produce:
-	// TRUNCATE mytable
-
-.. note:: If the TRUNCATE command isn't available, truncate() will
-	execute as "DELETE FROM table".
-
-**$this->db->get_compiled_delete()**
-
-This works exactly the same way as ``$this->db->get_compiled_insert()`` except
-that it produces a DELETE SQL string instead of an INSERT SQL string.
-
-For more information view documentation for $this->db->get_compiled_insert().
-
-***************
-Method Chaining
-***************
-
-Method chaining allows you to simplify your syntax by connecting
-multiple functions. Consider this example::
-
-	$query = $this->db->select('title')
-			->where('id', $id)
-			->limit(10, 20)
-			->get('mytable');
-
-.. _ar-caching:
-
-*********************
-Query Builder Caching
-*********************
-
-While not "true" caching, Query Builder enables you to save (or "cache")
-certain parts of your queries for reuse at a later point in your
-script's execution. Normally, when an Query Builder call is completed,
-all stored information is reset for the next call. With caching, you can
-prevent this reset, and reuse information easily.
-
-Cached calls are cumulative. If you make 2 cached select() calls, and
-then 2 uncached select() calls, this will result in 4 select() calls.
-There are three Caching functions available:
-
-**$this->db->start_cache()**
-
-This function must be called to begin caching. All Query Builder queries
-of the correct type (see below for supported queries) are stored for
-later use.
-
-**$this->db->stop_cache()**
-
-This function can be called to stop caching.
-
-**$this->db->flush_cache()**
-
-This function deletes all items from the Query Builder cache.
-
-An example of caching
----------------------
-
-Here's a usage example::
-
-	$this->db->start_cache();
-	$this->db->select('field1');
-	$this->db->stop_cache();
-	$this->db->get('tablename');
-	//Generates: SELECT `field1` FROM (`tablename`)
-
-	$this->db->select('field2');
-	$this->db->get('tablename');
-	//Generates:  SELECT `field1`, `field2` FROM (`tablename`)
-
-	$this->db->flush_cache();
-	$this->db->select('field2');
-	$this->db->get('tablename');
-	//Generates:  SELECT `field2` FROM (`tablename`)
-
-
-.. note:: The following statements can be cached: select, from, join,
-	where, like, group_by, having, order_by
-
-
-***********************
-Resetting Query Builder
-***********************
-
-**$this->db->reset_query()**
-
-Resetting Query Builder allows you to start fresh with your query without
-executing it first using a method like $this->db->get() or $this->db->insert().
-Just like the methods that execute a query, this will *not* reset items you've
-cached using `Query Builder Caching`_.
-
-This is useful in situations where you are using Query Builder to generate SQL
-(ex. ``$this->db->get_compiled_select()``) but then choose to, for instance,
-run the query::
-
-	// Note that the second parameter of the get_compiled_select method is FALSE
-	$sql = $this->db->select(array('field1','field2'))
-					->where('field3',5)
-					->get_compiled_select('mytable', FALSE);
-
-	// ...
-	// Do something crazy with the SQL code... like add it to a cron script for
-	// later execution or something...
-	// ...
-
-	$data = $this->db->get()->result_array();
-
-	// Would execute and return an array of results of the following query:
-	// SELECT field1, field1 from mytable where field3 = 5;
-
-.. note:: Double calls to ``get_compiled_select()`` while you're using the
-	Query Builder Caching functionality and NOT resetting your queries
-	will results in the cache being merged twice. That in turn will
-	i.e. if you're caching a ``select()`` - select the same field twice.

-Generating Query Results
-########################
-
-There are several ways to generate query results:
-
-.. contents::
-    :local:
-    :depth: 2
-
-*************
-Result Arrays
-*************
-
-**result()**
-
-This method returns the query result as an array of **objects**, or
-**an empty array** on failure. Typically you'll use this in a foreach
-loop, like this::
-
-	$query = $this->db->query("YOUR QUERY");
-
-	foreach ($query->result() as $row)
-	{
-		echo $row->title;
-		echo $row->name;
-		echo $row->body;
-	}
-
-The above method is an alias of ``result_object()``.
-
-You can also pass a string to ``result()`` which represents a class to
-instantiate for each result object (note: this class must be loaded)
-
-::
-
-	$query = $this->db->query("SELECT * FROM users;");
-
-	foreach ($query->result('User') as $user)
-	{
-		echo $user->name; // access attributes
-		echo $user->reverse_name(); // or methods defined on the 'User' class
-	}
-
-**result_array()**
-
-This method returns the query result as a pure array, or an empty
-array when no result is produced. Typically you'll use this in a foreach
-loop, like this::
-
-	$query = $this->db->query("YOUR QUERY");
-
-	foreach ($query->result_array() as $row)
-	{
-		echo $row['title'];
-		echo $row['name'];
-		echo $row['body'];
-	}
-
-***********
-Result Rows
-***********
-
-**row()**
-
-This method returns a single result row. If your query has more than
-one row, it returns only the first row. The result is returned as an
-**object**. Here's a usage example::
-
-	$query = $this->db->query("YOUR QUERY");
-
-	$row = $query->row();
-
-	if (isset($row))
-	{
-		echo $row->title;
-		echo $row->name;
-		echo $row->body;
-	}
-
-If you want a specific row returned you can submit the row number as a
-digit in the first parameter::
-
-	$row = $query->row(5);
-
-You can also add a second String parameter, which is the name of a class
-to instantiate the row with::
-
-	$query = $this->db->query("SELECT * FROM users LIMIT 1;");
-	$row = $query->row(0, 'User');
-	
-	echo $row->name; // access attributes
-	echo $row->reverse_name(); // or methods defined on the 'User' class
-
-**row_array()**
-
-Identical to the above ``row()`` method, except it returns an array.
-Example::
-
-	$query = $this->db->query("YOUR QUERY");
-
-	$row = $query->row_array();
-
-	if (isset($row))
-	{
-		echo $row['title'];
-		echo $row['name'];
-		echo $row['body'];
-	}
-
-If you want a specific row returned you can submit the row number as a
-digit in the first parameter::
-
-	$row = $query->row_array(5);
-
-In addition, you can walk forward/backwards/first/last through your
-results using these variations:
-
-	| **$row = $query->first_row()**
-	| **$row = $query->last_row()**
-	| **$row = $query->next_row()**
-	| **$row = $query->previous_row()**
-
-By default they return an object unless you put the word "array" in the
-parameter:
-
-	| **$row = $query->first_row('array')**
-	| **$row = $query->last_row('array')**
-	| **$row = $query->next_row('array')**
-	| **$row = $query->previous_row('array')**
-
-.. note:: All the methods above will load the whole result into memory
-	(prefetching). Use ``unbuffered_row()`` for processing large
-	result sets.
-
-**unbuffered_row()**
-
-This method returns a single result row without prefetching the whole
-result in memory as ``row()`` does. If your query has more than one row,
-it returns the current row and moves the internal data pointer ahead. 
-
-::
-
-	$query = $this->db->query("YOUR QUERY");
-
-	while ($row = $query->unbuffered_row())
-	{	
-		echo $row->title;
-		echo $row->name;
-		echo $row->body;
-	}
-
-You can optionally pass 'object' (default) or 'array' in order to specify
-the returned value's type::
-
-	$query->unbuffered_row();		// object
-	$query->unbuffered_row('object');	// object
-	$query->unbuffered_row('array');	// associative array
-
-*********************
-Custom Result Objects
-*********************
-
-You can have the results returned as an instance of a custom class instead
-of a ``stdClass`` or array, as the ``result()`` and ``result_array()``
-methods allow. This requires that the class is already loaded into memory.
-The object will have all values returned from the database set as properties.
-If these have been declared and are non-public then you should provide a
-``__set()`` method to allow them to be set.
-
-Example::
-
-	class User {
-
-		public $id;
-		public $email;
-		public $username;
-
-		protected $last_login;
-
-		public function last_login($format)
-		{
-			return $this->last_login->format($format);
-		}
-
-		public function __set($name, $value)
-		{
-			if ($name === 'last_login')
-			{
-				$this->last_login = DateTime::createFromFormat('U', $value);
-			}
-		}
-
-		public function __get($name)
-		{
-			if (isset($this->$name))
-			{
-				return $this->$name;
-			}
-		}
-	}
-
-In addition to the two methods listed below, the following methods also can
-take a class name to return the results as: ``first_row()``, ``last_row()``,
-``next_row()``, and ``previous_row()``.
-
-**custom_result_object()**
-
-Returns the entire result set as an array of instances of the class requested.
-The only parameter is the name of the class to instantiate.
-
-Example::
-
-	$query = $this->db->query("YOUR QUERY");
-
-	$rows = $query->custom_result_object('User');
-
-	foreach ($rows as $row)
-	{
-		echo $row->id;
-		echo $row->email;
-		echo $row->last_login('Y-m-d');
-	}
-
-**custom_row_object()**
-
-Returns a single row from your query results. The first parameter is the row
-number of the results. The second parameter is the class name to instantiate.
-
-Example::
-
-	$query = $this->db->query("YOUR QUERY");
-
-	$row = $query->custom_row_object(0, 'User');
-
-	if (isset($row))
-	{
-		echo $row->email;   // access attributes
-		echo $row->last_login('Y-m-d');   // access class methods
-	}
-
-You can also use the ``row()`` method in exactly the same way.
-
-Example::
-
-	$row = $query->custom_row_object(0, 'User');
-
-*********************
-Result Helper Methods
-*********************
-
-**num_rows()**
-
-The number of rows returned by the query. Note: In this example, $query
-is the variable that the query result object is assigned to::
-
-	$query = $this->db->query('SELECT * FROM my_table');
-
-	echo $query->num_rows();
-
-.. note:: Not all database drivers have a native way of getting the total
-	number of rows for a result set. When this is the case, all of
-	the data is prefetched and ``count()`` is manually called on the
-	resulting array in order to achieve the same result.
-	
-**num_fields()**
-
-The number of FIELDS (columns) returned by the query. Make sure to call
-the method using your query result object::
-
-	$query = $this->db->query('SELECT * FROM my_table');
-
-	echo $query->num_fields();
-
-**free_result()**
-
-It frees the memory associated with the result and deletes the result
-resource ID. Normally PHP frees its memory automatically at the end of
-script execution. However, if you are running a lot of queries in a
-particular script you might want to free the result after each query
-result has been generated in order to cut down on memory consumption.
-
-Example::
-
-	$query = $this->db->query('SELECT title FROM my_table');
-
-	foreach ($query->result() as $row)
-	{
-		echo $row->title;
-	}
-
-	$query->free_result();  // The $query result object will no longer be available
-
-	$query2 = $this->db->query('SELECT name FROM some_table');
-
-	$row = $query2->row();
-	echo $row->name;
-	$query2->free_result(); // The $query2 result object will no longer be available
-
-**data_seek()**
-
-This method sets the internal pointer for the next result row to be
-fetched. It is only useful in combination with ``unbuffered_row()``.
-
-It accepts a positive integer value, which defaults to 0 and returns
-TRUE on success or FALSE on failure.
-
-::
-
-	$query = $this->db->query('SELECT `field_name` FROM `table_name`');
-	$query->data_seek(5); // Skip the first 5 rows
-	$row = $query->unbuffered_row();
-
-.. note:: Not all database drivers support this feature and will return FALSE.
-	Most notably - you won't be able to use it with PDO.

-############
-Transactions
-############
-
-CodeIgniter's database abstraction allows you to use transactions with
-databases that support transaction-safe table types. In MySQL, you'll
-need to be running InnoDB or BDB table types rather than the more common
-MyISAM. Most other database platforms support transactions natively.
-
-If you are not familiar with transactions we recommend you find a good
-online resource to learn about them for your particular database. The
-information below assumes you have a basic understanding of
-transactions.
-
-CodeIgniter's Approach to Transactions
-======================================
-
-CodeIgniter utilizes an approach to transactions that is very similar to
-the process used by the popular database class ADODB. We've chosen that
-approach because it greatly simplifies the process of running
-transactions. In most cases all that is required are two lines of code.
-
-Traditionally, transactions have required a fair amount of work to
-implement since they demand that you keep track of your queries and
-determine whether to commit or rollback based on the success or failure
-of your queries. This is particularly cumbersome with nested queries. In
-contrast, we've implemented a smart transaction system that does all
-this for you automatically (you can also manage your transactions
-manually if you choose to, but there's really no benefit).
-
-Running Transactions
-====================
-
-To run your queries using transactions you will use the
-$this->db->trans_start() and $this->db->trans_complete() functions as
-follows::
-
-	$this->db->trans_start();
-	$this->db->query('AN SQL QUERY...');
-	$this->db->query('ANOTHER QUERY...');
-	$this->db->query('AND YET ANOTHER QUERY...');
-	$this->db->trans_complete();
-
-You can run as many queries as you want between the start/complete
-functions and they will all be committed or rolled back based on success
-or failure of any given query.
-
-Strict Mode
-===========
-
-By default CodeIgniter runs all transactions in Strict Mode. When strict
-mode is enabled, if you are running multiple groups of transactions, if
-one group fails all groups will be rolled back. If strict mode is
-disabled, each group is treated independently, meaning a failure of one
-group will not affect any others.
-
-Strict Mode can be disabled as follows::
-
-	$this->db->trans_strict(FALSE);
-
-Managing Errors
-===============
-
-If you have error reporting enabled in your config/database.php file
-you'll see a standard error message if the commit was unsuccessful. If
-debugging is turned off, you can manage your own errors like this::
-
-	$this->db->trans_start();
-	$this->db->query('AN SQL QUERY...');
-	$this->db->query('ANOTHER QUERY...');
-	$this->db->trans_complete();
-	
-	if ($this->db->trans_status() === FALSE)
-	{
-		// generate an error... or use the log_message() function to log your error
-	}
-
-Disabling Transactions
-======================
-
-If you would like to disable transactions you can do so using
-``$this->db->trans_off()``::
-
-	$this->db->trans_off();
-	
-	$this->db->trans_start();
-	$this->db->query('AN SQL QUERY...');
-	$this->db->trans_complete();
-
-When transactions are disabled, your queries will be auto-committed, just as
-they are when running queries without transactions, practically ignoring
-any calls to ``trans_start()``, ``trans_complete()``, etc.
-
-Test Mode
-=========
-
-You can optionally put the transaction system into "test mode", which
-will cause your queries to be rolled back -- even if the queries produce
-a valid result. To use test mode simply set the first parameter in the
-$this->db->trans_start() function to TRUE::
-
-	$this->db->trans_start(TRUE); // Query will be rolled back
-	$this->db->query('AN SQL QUERY...');
-	$this->db->trans_complete();
-
-Running Transactions Manually
-=============================
-
-If you would like to run transactions manually you can do so as follows::
-
-	$this->db->trans_begin();
-	
-	$this->db->query('AN SQL QUERY...');
-	$this->db->query('ANOTHER QUERY...');
-	$this->db->query('AND YET ANOTHER QUERY...');
-	
-	if ($this->db->trans_status() === FALSE)
-	{
-		$this->db->trans_rollback();
-	}
-	else
-	{
-		$this->db->trans_commit();
-	}
-
-.. note:: Make sure to use $this->db->trans_begin() when running manual
-	transactions, **NOT** $this->db->trans_start().

-Database Utility Class
-######################
-
-The Database Utility Class contains methods that help you manage your
-database.
-
-.. contents::
-    :local:
-    :depth: 2
-
-******************************
-Initializing the Utility Class
-******************************
-
-.. important:: In order to initialize the Utility class, your database
-	driver must already be running, since the utilities class relies on it.
-
-Load the Utility Class as follows::
-
-	$this->load->dbutil();
-
-You can also pass another database object to the DB Utility loader, in case
-the database you want to manage isn't the default one::
-
-	$this->myutil = $this->load->dbutil($this->other_db, TRUE);
-
-In the above example, we're passing a custom database object as the first
-parameter and then tell it to return the dbutil object, instead of
-assigning it directly to ``$this->dbutil``.
-
-.. note:: Both of the parameters can be used individually, just pass an empty
-	value as the first one if you wish to skip it.
-
-Once initialized you will access the methods using the ``$this->dbutil``
-object::
-
-	$this->dbutil->some_method();
-
-****************************
-Using the Database Utilities
-****************************
-
-Retrieve list of database names
-================================
-
-Returns an array of database names::
-
-	$dbs = $this->dbutil->list_databases();
-
-	foreach ($dbs as $db)
-	{
- 		echo $db;
-	}
-
-
-Determine If a Database Exists
-==============================
-
-Sometimes it's helpful to know whether a particular database exists.
-Returns a boolean TRUE/FALSE. Usage example::
-
-	if ($this->dbutil->database_exists('database_name'))
-	{
-		// some code...
-	}
-
-.. note:: Replace *database_name* with the name of the database you are
-	looking for. This method is case sensitive.
-
-Optimize a Table
-================
-
-Permits you to optimize a table using the table name specified in the
-first parameter. Returns TRUE/FALSE based on success or failure::
-
-	if ($this->dbutil->optimize_table('table_name'))
-	{
-		echo 'Success!';
-	}
-
-.. note:: Not all database platforms support table optimization. It is
-	mostly for use with MySQL.
-
-Repair a Table
-==============
-
-Permits you to repair a table using the table name specified in the
-first parameter. Returns TRUE/FALSE based on success or failure::
-
-	if ($this->dbutil->repair_table('table_name'))
-	{
-		echo 'Success!';
-	}
-
-.. note:: Not all database platforms support table repairs.
-
-Optimize a Database
-===================
-
-Permits you to optimize the database your DB class is currently
-connected to. Returns an array containing the DB status messages or
-FALSE on failure.
-
-::
-
-	$result = $this->dbutil->optimize_database();
-
-	if ($result !== FALSE)
-	{
-		print_r($result);
-	}
-
-.. note:: Not all database platforms support database optimization. It
-	it is mostly for use with MySQL.
-
-Export a Query Result as a CSV File
-===================================
-
-Permits you to generate a CSV file from a query result. The first
-parameter of the method must contain the result object from your
-query. Example::
-
-	$this->load->dbutil();
-
-	$query = $this->db->query("SELECT * FROM mytable");
-
-	echo $this->dbutil->csv_from_result($query);
-
-The second, third, and fourth parameters allow you to set the delimiter
-newline, and enclosure characters respectively. By default commas are
-used as the delimiter, "\n" is used as a new line, and a double-quote
-is used as the enclosure. Example::
-
-	$delimiter = ",";
-	$newline = "\r\n";
-	$enclosure = '"';
-
-	echo $this->dbutil->csv_from_result($query, $delimiter, $newline, $enclosure);
-
-.. important:: This method will NOT write the CSV file for you. It
-	simply creates the CSV layout. If you need to write the file
-	use the :doc:`File Helper <../helpers/file_helper>`.
-
-Export a Query Result as an XML Document
-========================================
-
-Permits you to generate an XML file from a query result. The first
-parameter expects a query result object, the second may contain an
-optional array of config parameters. Example::
-
-	$this->load->dbutil();
-
-	$query = $this->db->query("SELECT * FROM mytable");
-
-	$config = array (
-		'root'		=> 'root',
-		'element'	=> 'element',
-		'newline'	=> "\n",
-		'tab'		=> "\t"
-	);
-
-	echo $this->dbutil->xml_from_result($query, $config);
-
-.. important:: This method will NOT write the XML file for you. It
-	simply creates the XML layout. If you need to write the file
-	use the :doc:`File Helper <../helpers/file_helper>`.
-
-********************
-Backup Your Database
-********************
-
-Database Backup Notes
-=====================
-
-Permits you to backup your full database or individual tables. The
-backup data can be compressed in either Zip or Gzip format.
-
-.. note:: This feature is only available for MySQL and Interbase/Firebird databases.
-
-.. note:: For Interbase/Firebird databases, the backup file name is the only parameter.
-
-		$this->dbutil->backup('db_backup_filename');
-
-.. note:: Due to the limited execution time and memory available to PHP,
-	backing up very large databases may not be possible. If your database is
-	very large you might need to backup directly from your SQL server via
-	the command line, or have your server admin do it for you if you do not
-	have root privileges.
-
-Usage Example
-=============
-
-::
-
-	// Load the DB utility class
-	$this->load->dbutil();
-
-	// Backup your entire database and assign it to a variable
-	$backup = $this->dbutil->backup();
-
-	// Load the file helper and write the file to your server
-	$this->load->helper('file');
-	write_file('/path/to/mybackup.gz', $backup);
-
-	// Load the download helper and send the file to your desktop
-	$this->load->helper('download');
-	force_download('mybackup.gz', $backup);
-
-Setting Backup Preferences
-==========================
-
-Backup preferences are set by submitting an array of values to the first
-parameter of the ``backup()`` method. Example::
-
-	$prefs = array(
-		'tables'	=> array('table1', 'table2'),	// Array of tables to backup.
-		'ignore'	=> array(),			// List of tables to omit from the backup
-		'format'	=> 'txt',			// gzip, zip, txt
-		'filename'	=> 'mybackup.sql',		// File name - NEEDED ONLY WITH ZIP FILES
-		'add_drop'	=> TRUE,			// Whether to add DROP TABLE statements to backup file
-		'add_insert'	=> TRUE,			// Whether to add INSERT data to backup file
-		'newline'	=> "\n"				// Newline character used in backup file
-	);
-
-	$this->dbutil->backup($prefs);
-

-Writing CodeIgniter Documentation
-#################################
-
-CodeIgniter uses Sphinx to generate its documentation in a variety of formats,
-using reStructuredText to handle the formatting.  If you are familiar with
-Markdown or Textile, you will quickly grasp reStructuredText.  The focus is
-on readability and user friendliness.
-While they can be quite technical, we always write for humans!
-
-A local table of contents should always be included, like the one below.
-It is created automatically by inserting the following:
-
-::
-
-	.. contents::
-		:local:
-
-	.. raw:: html
-
-	<div class="custom-index container"></div>
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-The <div> that is inserted as raw HTML is a hook for the documentation's
-JavaScript to dynamically add links to any function and method definitions
-contained in the current page.
-
-**************
-Tools Required
-**************
-
-To see the rendered HTML, ePub, PDF, etc., you will need to install Sphinx
-along with the PHP domain extension for Sphinx.  The underlying requirement
-is to have Python installed.  Lastly, you will install the CI Lexer for
-Pygments, so that code blocks can be properly highlighted.
-
-.. code-block:: bash
-
-	easy_install "sphinx==1.2.3"
-	easy_install "sphinxcontrib-phpdomain==0.1.3.post1"
-
-Then follow the directions in the README file in the :samp:`cilexer` folder
-inside the documentation repository to install the CI Lexer.
-
-
-
-*****************************************
-Page and Section Headings and Subheadings
-*****************************************
-
-Headings not only provide order and sections within a page, but they also
-are used to automatically build both the page and document table of contents.
-Headings are formed by using certain characters as underlines for a bit of
-text.  Major headings, like page titles and section headings also use
-overlines.  Other headings just use underlines, with the following hierarchy::
-
-	# with overline for page titles
-	* with overline for major sections
-	= for subsections
-	- for subsubsections
-	^ for subsubsubsections
-	" for subsubsubsubsections (!)
-
-The :download:`TextMate ELDocs Bundle <./ELDocs.tmbundle.zip>` can help you
-create these with the following tab triggers::
-
-	title->
-
-		##########
-		Page Title
-		##########
-
-	sec->
-
-		*************
-		Major Section
-		*************
-
-	sub->
-
-		Subsection
-		==========
-
-	sss->
-
-		SubSubSection
-		-------------
-
-	ssss->
-
-		SubSubSubSection
-		^^^^^^^^^^^^^^^^
-
-	sssss->
-
-		SubSubSubSubSection (!)
-		"""""""""""""""""""""""
-
-
-
-
-********************
-Method Documentation
-********************
-
-When documenting class methods for third party developers, Sphinx provides
-directives to assist and keep things simple.  
-For example, consider the following ReST:
-
-.. code-block:: rst
-
-	.. php:class:: Some_class
-
-		.. php:method:: some_method ( $foo [, $bar [, $bat]])
-
-			This function will perform some action. The ``$bar`` array must contain
-			a something and something else, and along with ``$bat`` is an optional
-			parameter.
-
-			:param int $foo: the foo id to do something in
-			:param mixed $bar: A data array that must contain a something and something else
-			:param bool $bat: whether or not to do something
-			:returns: FALSE on failure, TRUE if successful
-			:rtype: bool
-
-			::
-
-				$this->load->library('some_class');
-
-				$bar = array(
-					'something'		=> 'Here is this parameter!',
-					'something_else'	=> 42
-				);
-
-				$bat = $this->some_class->should_do_something();
-
-				if ($this->some_class->some_method(4, $bar, $bat) === FALSE)
-				{
-					show_error('An Error Occurred Doing Some Method');
-				}
-
-			.. note:: Here is something that you should be aware of when using some_method().
-					For real.
-
-			See also :meth:`Some_class::should_do_something`
-
-
-		.. php:method:: should_do_something()
-
-			:returns: Whether or not something should be done
-			:rtype: bool
-
-
-It creates the following display:
-
-.. php:class:: Some_class
-
-
-	.. php:method:: some_method ( $foo [, $bar [, $bat]])
-
-		This function will perform some action. The ``$bar`` array must contain

-		parameter.
-
-		:param int $foo: the foo id to do something in

-###################################
-Alternate PHP Syntax for View Files
-###################################
-
-If you do not utilize CodeIgniter's :doc:`template
-engine <../libraries/parser>`, you'll be using pure PHP in your
-View files. To minimize the PHP code in these files, and to make it
-easier to identify the code blocks it is recommended that you use PHPs
-alternative syntax for control structures and short tag echo statements.
-If you are not familiar with this syntax, it allows you to eliminate the
-braces from your code, and eliminate "echo" statements.
-
-Automatic Short Tag Support
-===========================
-
-.. note:: If you find that the syntax described in this page does not
-	work on your server it might be that "short tags" are disabled in your
-	PHP ini file. CodeIgniter will optionally rewrite short tags on-the-fly,
-	allowing you to use that syntax even if your server doesn't support it.
-	This feature can be enabled in your *config/config.php* file.
-
-Please note that if you do use this feature, if PHP errors are
-encountered in your **view files**, the error message and line number
-will not be accurately shown. Instead, all errors will be shown as
-``eval()`` errors.
-
-Alternative Echos
-=================
-
-Normally to echo, or print out a variable you would do this::
-
-	<?php echo $variable; ?>
-
-With the alternative syntax you can instead do it this way::
-
-	<?=$variable?>
-
-Alternative Control Structures
-==============================
-
-Controls structures, like if, for, foreach, and while can be written in
-a simplified format as well. Here is an example using ``foreach``::
-
-	<ul>
-
-	<?php foreach ($todo as $item): ?>
-
-		<li><?=$item?></li>
-
-	<?php endforeach; ?>
-
-	</ul>
-
-Notice that there are no braces. Instead, the end brace is replaced with
-``endforeach``. Each of the control structures listed above has a similar
-closing syntax: ``endif``, ``endfor``, ``endforeach``, and ``endwhile``
-
-Also notice that instead of using a semicolon after each structure
-(except the last one), there is a colon. This is important!
-
-Here is another example, using ``if``/``elseif``/``else``. Notice the colons::
-
-	<?php if ($username === 'sally'): ?>
-
-		<h3>Hi Sally</h3>
-
-	<?php elseif ($username === 'joe'): ?>
-
-		<h3>Hi Joe</h3>
-
-	<?php else: ?>
-
-		<h3>Hi unknown user</h3>
-
-	<?php endif; ?>

-##########################
-Creating Ancillary Classes
-##########################
-
-In some cases you may want to develop classes that exist apart from your
-controllers but have the ability to utilize all of CodeIgniter's
-resources. This is easily possible as you'll see.
-
-get_instance()
-==============
-
-.. php:function:: get_instance()
-
-	:returns:	Reference to your controller's instance
-	:rtype:	CI_Controller
-
-**Any class that you instantiate within your controller methods can
-access CodeIgniter's native resources** simply by using the
-``get_instance()`` function. This function returns the main
-CodeIgniter object.
-
-Normally, to call any of the available methods, CodeIgniter requires
-you to use the ``$this`` construct::
-
-	$this->load->helper('url');
-	$this->load->library('session');
-	$this->config->item('base_url');
-	// etc.
-
-``$this``, however, only works within your controllers, your models,
-or your views. If you would like to use CodeIgniter's classes from
-within your own custom classes you can do so as follows:
-
-First, assign the CodeIgniter object to a variable::
-
-	$CI =& get_instance();
-
-Once you've assigned the object to a variable, you'll use that variable
-*instead* of ``$this``::
-
-	$CI =& get_instance();
-
-	$CI->load->helper('url');
-	$CI->load->library('session');
-	$CI->config->item('base_url');
-	// etc.
-
-If you'll be using ``get_instance()`` inside another class, then it would
-be better if you assign it to a property. This way, you won't need to call
-``get_instance()`` in every single method.
-
-Example::
-
-	class Example {
-
-		protected $CI;
-
-		// We'll use a constructor, as you can't directly call a function
-		// from a property definition.
-		public function __construct()
-		{
-			// Assign the CodeIgniter super-object
-			$this->CI =& get_instance();
-		}
-
-		public function foo()
-		{
-			$this->CI->load->helper('url');
-			redirect();
-		}
-
-		public function bar()
-		{
-			$this->CI->config->item('base_url');
-		}
-	}
-
-In the above example, both methods ``foo()`` and ``bar()`` will work
-after you instantiate the Example class, without the need to call
-``get_instance()`` in each of them.

-######################
-Auto-loading Resources
-######################
-
-CodeIgniter comes with an "Auto-load" feature that permits libraries,
-helpers, and models to be initialized automatically every time the
-system runs. If you need certain resources globally throughout your
-application you should consider auto-loading them for convenience.
-
-The following items can be loaded automatically:
-
--  Classes found in the *libraries/* directory
--  Helper files found in the *helpers/* directory
--  Custom config files found in the *config/* directory
--  Language files found in the *system/language/* directory
--  Models found in the *models/* folder
-
-To autoload resources, open the **application/config/autoload.php**
-file and add the item you want loaded to the autoload array. You'll
-find instructions in that file corresponding to each type of item.
-
-.. note:: Do not include the file extension (.php) when adding items to
-	the autoload array.
-
-Additionally, if you want CodeIgniter to use a `Composer <https://getcomposer.org/>`_
-auto-loader, just set ``$config['composer_autoload']`` to ``TRUE`` or
-a custom path in **application/config/config.php**.

-################
-Web Page Caching
-################
-
-CodeIgniter lets you cache your pages in order to achieve maximum
-performance.
-
-Although CodeIgniter is quite fast, the amount of dynamic information
-you display in your pages will correlate directly to the server
-resources, memory, and processing cycles utilized, which affect your
-page load speeds. By caching your pages, since they are saved in their
-fully rendered state, you can achieve performance that nears that of
-static web pages.
-
-How Does Caching Work?
-======================
-
-Caching can be enabled on a per-page basis, and you can set the length
-of time that a page should remain cached before being refreshed. When a
-page is loaded for the first time, the cache file will be written to
-your application/cache folder. On subsequent page loads the cache file
-will be retrieved and sent to the requesting user's browser. If it has
-expired, it will be deleted and refreshed before being sent to the
-browser.
-
-.. note: The Benchmark tag is not cached so you can still view your page
-	load speed when caching is enabled.
-
-Enabling Caching
-================
-
-To enable caching, put the following tag in any of your controller
-methods::
-
-	$this->output->cache($n);
-
-Where ``$n`` is the number of **minutes** you wish the page to remain
-cached between refreshes.
-
-The above tag can go anywhere within a method. It is not affected by
-the order that it appears, so place it wherever it seems most logical to
-you. Once the tag is in place, your pages will begin being cached.
-
-.. important:: Because of the way CodeIgniter stores content for output,
-	caching will only work if you are generating display for your
-	controller with a :doc:`view <./views>`.
-
-.. important:: If you change configuration options that might affect
-	your output, you have to manually delete your cache files.
-
-.. note:: Before the cache files can be written you must set the file
-	permissions on your *application/cache/* directory such that
-	it is writable.
-
-Deleting Caches
-===============
-
-If you no longer wish to cache a file you can remove the caching tag and
-it will no longer be refreshed when it expires.
-
-.. note:: Removing the tag will not delete the cache immediately. It will
-	have to expire normally.
-
-If you need to manually delete the cache, you can use the ``delete_cache()``
-method::
-
-	// Deletes cache for the currently requested URI
-	$this->output->delete_cache();
-
-	// Deletes cache for /foo/bar
-	$this->output->delete_cache('/foo/bar');

-Running via the CLI
-###################
-
-As well as calling an applications :doc:`Controllers <./controllers>`
-via the URL in a browser they can also be loaded via the command-line
-interface (CLI).
-
-.. contents:: Page Contents
-
-What is the CLI?
-================
-
-The command-line interface is a text-based method of interacting with
-computers. For more information, check the `Wikipedia
-article <http://en.wikipedia.org/wiki/Command-line_interface>`_.
-
-Why run via the command-line?
-=============================
-
-There are many reasons for running CodeIgniter from the command-line,
-but they are not always obvious.
-
--  Run your cron-jobs without needing to use *wget* or *curl*
--  Make your cron-jobs inaccessible from being loaded in the URL by
-   checking the return value of :php:func:`is_cli()`.
--  Make interactive "tasks" that can do things like set permissions,
-   prune cache folders, run backups, etc.
--  Integrate with other applications in other languages. For example, a
-   random C++ script could call one command and run code in your models!
-
-Let's try it: Hello World!
-==========================
-
-Let's create a simple controller so you can see it in action. Using your
-text editor, create a file called Tools.php, and put the following code
-in it::

-	<?php
-	class Tools extends CI_Controller {
-
-		public function message($to = 'World')
-		{
-			echo "Hello {$to}!".PHP_EOL;
-		}
-	}
-
-Then save the file to your *application/controllers/* folder.
-
-Now normally you would visit the site using a URL similar to this::
-
-	example.com/index.php/tools/message/to
-
-Instead, we are going to open the terminal in Mac/Linux or go to Run > "cmd"
-in Windows and navigate to our CodeIgniter project.
-
-.. code-block:: bash
-
-	$ cd /path/to/project;
-	$ php index.php tools message
-
-If you did it right, you should see *Hello World!* printed.
-
-.. code-block:: bash
-
-	$ php index.php tools message "John Smith"
-
-Here we are passing it a argument in the same way that URL parameters
-work. "John Smith" is passed as a argument and output is::
-
-	Hello John Smith!
-
-That's it!
-==========
-
-That, in a nutshell, is all there is to know about controllers on the
-command line. Remember that this is just a normal controller, so routing
-and ``_remap()`` works fine.

-Common Functions
-################
-
-CodeIgniter uses a few functions for its operation that are globally
-defined, and are available to you at any point. These do not require
-loading any libraries or helpers.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-.. php:function:: is_php($version)
-
-	:param	string	$version: Version number
-	:returns:	TRUE if the running PHP version is at least the one specified or FALSE if not
-	:rtype:	bool
-
-	Determines if the PHP version being used is greater than the
-	supplied version number.
-
-	Example::
-
-		if (is_php('5.3'))
-		{
-			$str = quoted_printable_encode($str);
-		}
-
-	Returns boolean TRUE if the installed version of PHP is equal to or
-	greater than the supplied version number. Returns FALSE if the installed
-	version of PHP is lower than the supplied version number.
-
-.. php:function:: is_really_writable($file)
-
-	:param	string	$file: File path
-	:returns:	TRUE if the path is writable, FALSE if not
-	:rtype:	bool
-
-	``is_writable()`` returns TRUE on Windows servers when you really can't
-	write to the file as the OS reports to PHP as FALSE only if the
-	read-only attribute is marked.
-
-	This function determines if a file is actually writable by attempting
-	to write to it first. Generally only recommended on platforms where
-	this information may be unreliable.
-
-	Example::
-
-		if (is_really_writable('file.txt'))
-		{
-			echo "I could write to this if I wanted to";
-		}
-		else
-		{
-			echo "File is not writable";
-		}
-
-	.. note:: See also `PHP bug #54709 <https://bugs.php.net/bug.php?id=54709>`_ for more info.
-
-.. php:function:: config_item($key)
-
-	:param	string	$key: Config item key
-	:returns:	Configuration key value or NULL if not found
-	:rtype:	mixed
-
-	The :doc:`Config Library <../libraries/config>` is the preferred way of
-	accessing configuration information, however ``config_item()`` can be used
-	to retrieve single keys. See :doc:`Config Library <../libraries/config>`
-	documentation for more information.
-
-.. :noindex: function:: show_error($message, $status_code[, $heading = 'An Error Was Encountered'])
-
-	:param	mixed	$message: Error message
-	:param	int	$status_code: HTTP Response status code
-	:param	string	$heading: Error page heading
-	:rtype:	void
-
-	This function calls ``CI_Exception::show_error()``. For more info,
-	please see the :doc:`Error Handling <errors>` documentation.
-
-.. :noindex: function:: show_404([$page = ''[, $log_error = TRUE]])
-
-	:param	string	$page: URI string
-	:param	bool	$log_error: Whether to log the error
-	:rtype:	void
-
-	This function calls ``CI_Exception::show_404()``. For more info,
-	please see the :doc:`Error Handling <errors>` documentation.
-
-.. :noindex: function:: log_message($level, $message)
-
-	:param	string	$level: Log level: 'error', 'debug' or 'info'
-	:param	string	$message: Message to log
-	:rtype:	void
-
-	This function is an alias for ``CI_Log::write_log()``. For more info,
-	please see the :doc:`Error Handling <errors>` documentation.
-
-.. php:function:: set_status_header($code[, $text = ''])
-
-	:param	int	$code: HTTP Response status code
-	:param	string	$text: A custom message to set with the status code
-	:rtype:	void
-
-	Permits you to manually set a server status header. Example::
-
-		set_status_header(401);
-		// Sets the header as:  Unauthorized
-
-	`See here <http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html>`_ for
-	a full list of headers.
-
-.. php:function:: remove_invisible_characters($str[, $url_encoded = TRUE])
-
-	:param	string	$str: Input string
-	:param	bool	$url_encoded: Whether to remove URL-encoded characters as well
-	:returns:	Sanitized string
-	:rtype:	string
-
-	This function prevents inserting NULL characters between ASCII
-	characters, like Java\\0script.
-
-	Example::
-
-		remove_invisible_characters('Java\\0script');
-		// Returns: 'Javascript'
-
-.. php:function:: html_escape($var)
-
-	:param	mixed	$var: Variable to escape (string or array)
-	:returns:	HTML escaped string(s)
-	:rtype:	mixed
-
-	This function acts as an alias for PHP's native ``htmlspecialchars()``
-	function, with the advantage of being able to accept an array of strings.
-
-	It is useful in preventing Cross Site Scripting (XSS).
-
-.. php:function:: get_mimes()
-
-	:returns:	An associative array of file types
-	:rtype:	array
-
-	This function returns a *reference* to the MIMEs array from
-	*application/config/mimes.php*.
-
-.. php:function:: is_https()
-
-	:returns:	TRUE if currently using HTTP-over-SSL, FALSE if not
-	:rtype:	bool
-
-	Returns TRUE if a secure (HTTPS) connection is used and FALSE
-	in any other case (including non-HTTP requests).
-
-.. php:function:: is_cli()
-
-	:returns:	TRUE if currently running under CLI, FALSE otherwise
-	:rtype:	bool
-
-	Returns TRUE if the application is run through the command line
-	and FALSE if not.
-
-	.. note:: This function checks both if the ``PHP_SAPI`` value is 'cli'
-		or if the ``STDIN`` constant is defined.
-
-.. php:function:: function_usable($function_name)
-
-	:param	string	$function_name: Function name
-	:returns:	TRUE if the function can be used, FALSE if not
-	:rtype:	bool
-
-	Returns TRUE if a function exists and is usable, FALSE otherwise.
-
-	This function runs a ``function_exists()`` check and if the
-	`Suhosin extension <http://www.hardened-php.net/suhosin/>` is loaded,
-	checks if it doesn't disable the function being checked.
-
-	It is useful if you want to check for the availability of functions
-	such as ``eval()`` and ``exec()``, which are dangerous and might be
-	disabled on servers with highly restrictive security policies.
-
-	.. note:: This function was introduced because Suhosin terminated
-		script execution, but this turned out to be a bug. A fix
-		has been available for some time (version 0.9.34), but is
-		unfortunately not released yet.

-Compatibility Functions
-#######################
-
-CodeIgniter provides a set of compatibility functions that enable
-you to use functions what are otherwise natively available in PHP,
-but only in higher versions or depending on a certain extension.
-
-Being custom implementations, these functions will also have some
-set of dependencies on their own, but are still useful if your
-PHP setup doesn't offer them natively.
-
-.. note:: Much like the :doc:`common functions <common_functions>`, the
-	compatibility functions are always available, as long as
-	their dependencies are met.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-****************
-Password Hashing
-****************
-

-that is otherwise available only since PHP 5.5.
-
-Dependencies
-============
-
-- PHP 5.3.7
-- ``CRYPT_BLOWFISH`` support for ``crypt()``
-
-Constants
-=========
-
-- ``PASSWORD_BCRYPT``
-- ``PASSWORD_DEFAULT``
-
-Function reference
-==================
-
-.. php:function:: password_get_info($hash)
-
-	:param	string	$hash: Password hash
-	:returns:	Information about the hashed password
-	:rtype:	array
-
-	For more information, please refer to the `PHP manual for

-
-	.. note:: Unless you provide your own (and valid) salt, this function
-		has a further dependency on an available CSPRNG source. Each
-		of the following would satisfy that:
-		- ``mcrypt_create_iv()`` with ``MCRYPT_DEV_URANDOM``
-		- ``openssl_random_pseudo_bytes()``
-		- /dev/arandom
-		- /dev/urandom
-
-.. php:function:: password_needs_rehash()
-
-	:param	string	$hash: Password hash
-	:param	int	$algo: Hashing algorithm
-	:param	array	$options: Hashing options
-	:returns:	TRUE if the hash should be rehashed to match the given algorithm and options, FALSE otherwise
-	:rtype:	bool
-
-	For more information, please refer to the `PHP manual for

-
-*********************
-Hash (Message Digest)
-*********************
-
-This compatibility layer contains backports for the ``hash_equals()``
-and ``hash_pbkdf2()`` functions, which otherwise require PHP 5.6 and/or
-PHP 5.5 respectively.
-
-Dependencies
-============
-
-- None

-
-****************
-Multibyte String
-****************
-
-This set of compatibility functions offers limited support for PHP's
-`Multibyte String extension <http://php.net/mbstring>`_. Because of
-the limited alternative solutions, only a few functions are available.
-
-.. note:: When a character set parameter is ommited,
-	``$config['charset']`` will be used.
-
-Dependencies
-============
-
-- `iconv <http://php.net/iconv>`_ extension
-
-.. important:: This dependency is optional and these functions will
-	always be declared. If iconv is not available, they WILL
-	fall-back to their non-mbstring versions.
-
-.. important:: Where a character set is supplied, it must be
-	supported by iconv and in a format that it recognizes.
-
-.. note:: For you own dependency check on the actual mbstring
-	extension, use the ``MB_ENABLED`` constant.
-

-	:rtype:	string
-
-	For more information, please refer to the `PHP manual for
-	mb_substr() <http://php.net/mb_substr>`_.
-
-******************
-Standard Functions
-******************
-
-This set of compatibility functions offers support for a few
-standard functions in PHP that otherwise require a newer PHP version.
-
-Dependencies

-Controllers
-###########
-
-Controllers are the heart of your application, as they determine how
-HTTP requests should be handled.
-
-.. contents:: Page Contents
-
-What is a Controller?
-=====================
-
-**A Controller is simply a class file that is named in a way that can be
-associated with a URI.**
-
-Consider this URI::
-
-	example.com/index.php/blog/
-
-In the above example, CodeIgniter would attempt to find a controller
-named Blog.php and load it.
-
-**When a controller's name matches the first segment of a URI, it will
-be loaded.**
-
-Let's try it: Hello World!
-==========================
-
-Let's create a simple controller so you can see it in action. Using your
-text editor, create a file called Blog.php, and put the following code
-in it::
-
-	<?php
-	class Blog extends CI_Controller {
-
-		public function index()
-		{
-			echo 'Hello World!';
-		}
-	}
-
-Then save the file to your *application/controllers/* directory.
-
-.. important:: The file must be called 'Blog.php', with a capital 'B'.
-
-Now visit the your site using a URL similar to this::
-
-	example.com/index.php/blog/
-
-If you did it right, you should see:
-
-	Hello World!
-
-.. important:: Class names must start with an uppercase letter.
-
-This is valid::
-
-	<?php
-	class Blog extends CI_Controller {
-
-	}
-	
-This is **not** valid::
-
-	<?php
-	class blog extends CI_Controller {
-
-	}
-
-Also, always make sure your controller extends the parent controller
-class so that it can inherit all its methods.
-
-Methods
-=======
-
-In the above example the method name is ``index()``. The "index" method
-is always loaded by default if the **second segment** of the URI is
-empty. Another way to show your "Hello World" message would be this::
-
-	example.com/index.php/blog/index/
-
-**The second segment of the URI determines which method in the
-controller gets called.**
-
-Let's try it. Add a new method to your controller::
-
-	<?php
-	class Blog extends CI_Controller {
-
-		public function index()
-		{
-			echo 'Hello World!';
-		}
-
-		public function comments()
-		{
-			echo 'Look at this!';
-		}
-	}
-
-Now load the following URL to see the comment method::
-
-	example.com/index.php/blog/comments/
-
-You should see your new message.
-
-Passing URI Segments to your methods
-====================================
-
-If your URI contains more than two segments they will be passed to your
-method as parameters.
-
-For example, let's say you have a URI like this::
-
-	example.com/index.php/products/shoes/sandals/123
-
-Your method will be passed URI segments 3 and 4 ("sandals" and "123")::
-
-	<?php
-	class Products extends CI_Controller {
-
-		public function shoes($sandals, $id)
-		{
-			echo $sandals;
-			echo $id;
-		}
-	}
-
-.. important:: If you are using the :doc:`URI Routing <routing>`
-	feature, the segments passed to your method will be the re-routed
-	ones.
-
-Defining a Default Controller
-=============================
-
-CodeIgniter can be told to load a default controller when a URI is not
-present, as will be the case when only your site root URL is requested.
-To specify a default controller, open your **application/config/routes.php**
-file and set this variable::
-
-	$route['default_controller'] = 'blog';
-
-Where 'blog' is the name of the controller class you want used. If you now
-load your main index.php file without specifying any URI segments you'll
-see your "Hello World" message by default.
-
-For more information, please refer to the "Reserved Routes" section of the
-:doc:`URI Routing <routing>` documentation.
-
-Remapping Method Calls
-======================
-
-As noted above, the second segment of the URI typically determines which
-method in the controller gets called. CodeIgniter permits you to override
-this behavior through the use of the ``_remap()`` method::
-
-	public function _remap()
-	{
-		// Some code here...
-	}
-
-.. important:: If your controller contains a method named _remap(),
-	it will **always** get called regardless of what your URI contains. It
-	overrides the normal behavior in which the URI determines which method
-	is called, allowing you to define your own method routing rules.
-
-The overridden method call (typically the second segment of the URI) will
-be passed as a parameter to the ``_remap()`` method::
-
-	public function _remap($method)
-	{
-		if ($method === 'some_method')
-		{
-			$this->$method();
-		}
-		else
-		{
-			$this->default_method();
-		}
-	}
-
-Any extra segments after the method name are passed into ``_remap()`` as an
-optional second parameter. This array can be used in combination with
-PHP's `call_user_func_array() <http://php.net/call_user_func_array>`_
-to emulate CodeIgniter's default behavior.
-
-Example::
-
-	public function _remap($method, $params = array())
-	{
-		$method = 'process_'.$method;
-		if (method_exists($this, $method))
-		{
-			return call_user_func_array(array($this, $method), $params);
-		}
-		show_404();
-	}
-
-Processing Output
-=================
-
-CodeIgniter has an output class that takes care of sending your final
-rendered data to the web browser automatically. More information on this
-can be found in the :doc:`Views <views>` and :doc:`Output Class
-<../libraries/output>` pages. In some cases, however, you might want to
-post-process the finalized data in some way and send it to the browser
-yourself. CodeIgniter permits you to add a method named ``_output()``
-to your controller that will receive the finalized output data.
-
-.. important:: If your controller contains a method named ``_output()``,
-	it will **always** be called by the output class instead of
-	echoing the finalized data directly. The first parameter of the
-	method will contain the finalized output.
-
-Here is an example::
-
-	public function _output($output)
-	{
-		echo $output;
-	}
-
-.. note::
-
-	Please note that your ``_output()`` method will receive the
-	data in its finalized state. Benchmark and memory usage data
-	will be rendered, cache files written (if you have caching
-	enabled), and headers will be sent (if you use that
-	:doc:`feature <../libraries/output>`) before it is handed off
-	to the ``_output()`` method.
-	To have your controller's output cached properly, its
-	``_output()`` method can use::
-
-		if ($this->output->cache_expiration > 0)
-		{
-			$this->output->_write_cache($output);
-		}
-
-	If you are using this feature the page execution timer and
-	memory usage stats might not be perfectly accurate since they
-	will not take into account any further processing you do.
-	For an alternate way to control output *before* any of the
-	final processing is done, please see the available methods
-	in the :doc:`Output Library <../libraries/output>`.
-
-Private methods
-===============
-
-In some cases you may want certain methods hidden from public access.
-In order to achieve this, simply declare the method as being private
-or protected and it will not be served via a URL request. For example,
-if you were to have a method like this::
-
-	private function _utility()
-	{
-		// some code
-	}
-
-Trying to access it via the URL, like this, will not work::
-
-	example.com/index.php/blog/_utility/
-
-.. note:: Prefixing method names with an underscore will also prevent
-	them from being called. This is a legacy feature that is left
-	for backwards-compatibility.
-
-Organizing Your Controllers into Sub-directories
-================================================
-
-If you are building a large application you might want to hierarchically
-organize or structure your controllers into sub-directories. CodeIgniter
-permits you to do this.
-
-Simply create sub-directories under the main *application/controllers/*
-one and place your controller classes within them.
-
-.. note:: When using this feature the first segment of your URI must
-	specify the folder. For example, let's say you have a controller located
-	here::
-
-		application/controllers/products/Shoes.php
-
-	To call the above controller your URI will look something like this::
-
-		example.com/index.php/products/shoes/show/123
-
-Each of your sub-directories may contain a default controller which will be
-called if the URL contains *only* the sub-directory. Simply put a controller
-in there that matches the name of your 'default_controller' as specified in
-your *application/config/routes.php* file.
-
-CodeIgniter also permits you to remap your URIs using its :doc:`URI
-Routing <routing>` feature.
-
-Class Constructors
-==================
-
-If you intend to use a constructor in any of your Controllers, you
-**MUST** place the following line of code in it::
-
-	parent::__construct();
-
-The reason this line is necessary is because your local constructor will
-be overriding the one in the parent controller class so we need to
-manually call it.
-
-Example::
-
-	<?php
-	class Blog extends CI_Controller {
-
-		public function __construct()
-		{
-			parent::__construct();
-			// Your own constructor code
-		}
-	}
-
-Constructors are useful if you need to set some default values, or run a
-default process when your class is instantiated. Constructors can't
-return a value, but they can do some default work.
-
-Reserved method names
-=====================
-
-Since your controller classes will extend the main application
-controller you must be careful not to name your methods identically to
-the ones used by that class, otherwise your local functions will
-override them. See :doc:`Reserved Names <reserved_names>` for a full
-list.
-
-.. important:: You should also never have a method named identically
-	to its class name. If you do, and there is no ``__construct()``
-	method in the same class, then your e.g. ``Index::index()``
-	method will be executed as a class constructor! This is a PHP4
-	backwards-compatibility feature.
-
-That's it!
-==========
-
-That, in a nutshell, is all there is to know about controllers.

-############################
-Creating Core System Classes
-############################
-
-Every time CodeIgniter runs there are several base classes that are
-initialized automatically as part of the core framework. It is possible,
-however, to swap any of the core system classes with your own versions
-or even extend the core versions.
-
-**Most users will never have any need to do this, but the option to
-replace or extend them does exist for those who would like to
-significantly alter the CodeIgniter core.**
-
-.. note:: Messing with a core system class has a lot of implications, so
-	make sure you know what you are doing before attempting it.
-
-System Class List
-=================
-
-The following is a list of the core system files that are invoked every
-time CodeIgniter runs:
-
--  Benchmark
--  Config
--  Controller
--  Exceptions
--  Hooks
--  Input
--  Language
--  Loader
--  Log
--  Output
--  Router
--  Security
--  URI
--  Utf8
-
-Replacing Core Classes
-======================
-
-To use one of your own system classes instead of a default one simply
-place your version inside your local *application/core/* directory::
-
-	application/core/some_class.php
-
-If this directory does not exist you can create it.
-
-Any file named identically to one from the list above will be used
-instead of the one normally used.
-
-Please note that your class must use CI as a prefix. For example, if
-your file is named Input.php the class will be named::
-
-	class CI_Input {
-
-	}
-
-Extending Core Class
-====================
-
-If all you need to do is add some functionality to an existing library -
-perhaps add a method or two - then it's overkill to replace the entire
-library with your version. In this case it's better to simply extend the
-class. Extending a class is nearly identical to replacing a class with a
-couple exceptions:
-
--  The class declaration must extend the parent class.
--  Your new class name and filename must be prefixed with MY\_ (this
-   item is configurable. See below.).
-
-For example, to extend the native Input class you'll create a file named
-application/core/MY_Input.php, and declare your class with::
-
-	class MY_Input extends CI_Input {
-
-	}
-
-.. note:: If you need to use a constructor in your class make sure you
-	extend the parent constructor::
-
-		class MY_Input extends CI_Input {
-
-			public function __construct()
-			{
-				parent::__construct();
-			}
-		}
-
-**Tip:** Any functions in your class that are named identically to the
-methods in the parent class will be used instead of the native ones
-(this is known as "method overriding"). This allows you to substantially
-alter the CodeIgniter core.
-
-If you are extending the Controller core class, then be sure to extend
-your new class in your application controller's constructors.
-
-::
-
-	class Welcome extends MY_Controller {
-
-		public function __construct()
-		{
-			parent::__construct();
-			// Your own constructor code
-		}
-
-		public function index()
-		{
-			$this->load->view('welcome_message');
-		}
-	}
-
-Setting Your Own Prefix
------------------------
-
-To set your own sub-class prefix, open your
-*application/config/config.php* file and look for this item::
-
-	$config['subclass_prefix'] = 'MY_';
-
-Please note that all native CodeIgniter libraries are prefixed
-with CI\_ so DO NOT use that as your prefix.

-Driver Directory and File Structure
-===================================
-
-Sample driver directory and file structure layout:

-      -  Driver_name_subclass_3.php
-
-.. note:: In order to maintain compatibility on case-sensitive
-	file systems, the Driver_name directory must be
-	named in the format returned by ``ucfirst()``.
-
-.. note:: The Driver library's architecture is such that
-	the subclasses don't extend and therefore don't inherit
-	properties or methods of the main driver.

-##################
-Creating Libraries
-##################
-
-When we use the term "Libraries" we are normally referring to the
-classes that are located in the libraries directory and described in the
-Class Reference of this user guide. In this case, however, we will
-instead describe how you can create your own libraries within your
-application/libraries directory in order to maintain separation between
-your local resources and the global framework resources.
-
-As an added bonus, CodeIgniter permits your libraries to extend native
-classes if you simply need to add some functionality to an existing
-library. Or you can even replace native libraries just by placing
-identically named versions in your *application/libraries* directory.
-
-In summary:
-
--  You can create entirely new libraries.
--  You can extend native libraries.
--  You can replace native libraries.
-
-The page below explains these three concepts in detail.
-
-.. note:: The Database classes can not be extended or replaced with your
-	own classes. All other classes are able to be replaced/extended.
-
-Storage
-=======
-
-Your library classes should be placed within your *application/libraries*
-directory, as this is where CodeIgniter will look for them when they are
-initialized.
-
-Naming Conventions
-==================
-
--  File names must be capitalized. For example: Myclass.php
--  Class declarations must be capitalized. For example: class Myclass
--  Class names and file names must match.
-
-The Class File
-==============
-
-Classes should have this basic prototype::
-
-	<?php
-	defined('BASEPATH') OR exit('No direct script access allowed'); 
-
-	class Someclass {
-
-		public function some_method()
-		{
-		}
-	}
-
-.. note:: We are using the name Someclass purely as an example.
-
-Using Your Class
-================
-
-From within any of your :doc:`Controller <controllers>` methods you
-can initialize your class using the standard::
-
-	$this->load->library('someclass');
-
-Where *someclass* is the file name, without the ".php" file extension.
-You can submit the file name capitalized or lower case. CodeIgniter
-doesn't care.
-
-Once loaded you can access your class using the lower case version::
-
-	$this->someclass->some_method();  // Object instances will always be lower case
-
-Passing Parameters When Initializing Your Class
-===============================================
-
-In the library loading method you can dynamically pass data as an
-array via the second parameter and it will be passed to your class
-constructor::
-
-	$params = array('type' => 'large', 'color' => 'red');
-
-	$this->load->library('someclass', $params);
-
-If you use this feature you must set up your class constructor to expect
-data::
-
-	<?php defined('BASEPATH') OR exit('No direct script access allowed');
-
-	class Someclass {
-
-		public function __construct($params)
-		{
-			// Do something with $params
-		}
-	}
-
-You can also pass parameters stored in a config file. Simply create a
-config file named identically to the class file name and store it in
-your *application/config/* directory. Note that if you dynamically pass
-parameters as described above, the config file option will not be
-available.
-
-Utilizing CodeIgniter Resources within Your Library
-===================================================
-
-To access CodeIgniter's native resources within your library use the
-``get_instance()`` method. This method returns the CodeIgniter super
-object.
-
-Normally from within your controller methods you will call any of the
-available CodeIgniter methods using the ``$this`` construct::
-
-	$this->load->helper('url');
-	$this->load->library('session');
-	$this->config->item('base_url');
-	// etc.
-
-``$this``, however, only works directly within your controllers, your
-models, or your views. If you would like to use CodeIgniter's classes
-from within your own custom classes you can do so as follows:
-
-First, assign the CodeIgniter object to a variable::
-
-	$CI =& get_instance();
-
-Once you've assigned the object to a variable, you'll use that variable
-*instead* of ``$this``::
-
-	$CI =& get_instance();
-
-	$CI->load->helper('url');
-	$CI->load->library('session');
-	$CI->config->item('base_url');
-	// etc.
-
-.. note:: You'll notice that the above ``get_instance()`` function is being
-	passed by reference::
-	
-		$CI =& get_instance();
-
-	This is very important. Assigning by reference allows you to use the
-	original CodeIgniter object rather than creating a copy of it.
-
-However, since a library is a class, it would be better if you
-take full advantage of the OOP principles. So, in order to
-be able to use the CodeIgniter super-object in all of the class
-methods, you're encouraged to assign it to a property instead::
-
-	class Example_library {
-
-		protected $CI;
-
-		// We'll use a constructor, as you can't directly call a function
-		// from a property definition.
-		public function __construct()
-		{
-			// Assign the CodeIgniter super-object
-			$this->CI =& get_instance();
-		}
-
-		public function foo()
-		{
-			$this->CI->load->helper('url');
-			redirect();
-		}
-
-		public function bar()
-		{
-			echo $this->CI->config->item('base_url');
-		}
-
-	}
-
-Replacing Native Libraries with Your Versions
-=============================================
-
-Simply by naming your class files identically to a native library will
-cause CodeIgniter to use it instead of the native one. To use this
-feature you must name the file and the class declaration exactly the
-same as the native library. For example, to replace the native Email
-library you'll create a file named *application/libraries/Email.php*,
-and declare your class with::
-
-	class CI_Email {
-	
-	}
-
-Note that most native classes are prefixed with CI\_.
-
-To load your library you'll see the standard loading method::
-
-	$this->load->library('email');
-
-.. note:: At this time the Database classes can not be replaced with
-	your own versions.
-
-Extending Native Libraries
-==========================
-
-If all you need to do is add some functionality to an existing library -
-perhaps add a method or two - then it's overkill to replace the entire
-library with your version. In this case it's better to simply extend the
-class. Extending a class is nearly identical to replacing a class with a
-couple exceptions:
-
--  The class declaration must extend the parent class.
--  Your new class name and filename must be prefixed with MY\_ (this
-   item is configurable. See below.).
-
-For example, to extend the native Email class you'll create a file named
-*application/libraries/MY_Email.php*, and declare your class with::
-
-	class MY_Email extends CI_Email {
-
-	}
-
-If you need to use a constructor in your class make sure you
-extend the parent constructor::
-
-	class MY_Email extends CI_Email {
-
-		public function __construct($config = array())
-		{
-			parent::__construct($config);
-		}
-
-	}
-
-.. note:: Not all of the libraries have the same (or any) parameters
-	in their constructor. Take a look at the library that you're
-	extending first to see how it should be implemented.
-
-Loading Your Sub-class
-----------------------
-
-To load your sub-class you'll use the standard syntax normally used. DO
-NOT include your prefix. For example, to load the example above, which
-extends the Email class, you will use::
-
-	$this->load->library('email');
-
-Once loaded you will use the class variable as you normally would for
-the class you are extending. In the case of the email class all calls
-will use::
-
-	$this->email->some_method();
-
-Setting Your Own Prefix
------------------------
-
-To set your own sub-class prefix, open your
-*application/config/config.php* file and look for this item::
-
-	$config['subclass_prefix'] = 'MY_';
-
-Please note that all native CodeIgniter libraries are prefixed with CI\_
-so DO NOT use that as your prefix.

-sub-systems borrowed from the code-base of `ExpressionEngine
-<https://ellislab.com/expressionengine>`_.
-
-It was, for years, developed and maintained by EllisLab, the ExpressionEngine
-Development Team and a group of community members called the Reactor Team.
-
-In 2014, CodeIgniter was acquired by the `British Columbia Institute of Technology
-<http://www.bcit.ca/>`_ and was then officially announced as a community-maintained
-project.
-
-Bleeding edge development is spearheaded by the handpicked contributors
-of the Reactor Team.
-
-A hat tip goes to Ruby on Rails for inspiring us to create a PHP framework, and
-for bringing frameworks into the general consciousness of the web community.

-#########################
-Using CodeIgniter Drivers
-#########################
-
-Drivers are a special type of Library that has a parent class and any
-number of potential child classes. Child classes have access to the
-parent class, but not their siblings. Drivers provide an elegant syntax
-in your :doc:`controllers <controllers>` for libraries that benefit
-from or require being broken down into discrete classes.
-
-Drivers are found in the *system/libraries/* directory, in their own
-sub-directory which is identically named to the parent library class.
-Also inside that directory is a subdirectory named drivers, which
-contains all of the possible child class files.
-
-To use a driver you will initialize it within a controller using the
-following initialization method::
-
-	$this->load->driver('class_name');
-
-Where class name is the name of the driver class you want to invoke. For
-example, to load a driver named "Some_parent" you would do this::
-
-	$this->load->driver('some_parent');
-
-Methods of that class can then be invoked with::
-
-	$this->some_parent->some_method();
-
-The child classes, the drivers themselves, can then be called directly
-through the parent class, without initializing them::
-
-	$this->some_parent->child_one->some_method();
-	$this->some_parent->child_two->another_method();
-
-Creating Your Own Drivers
-=========================

-Please read the section of the user guide that discusses how to :doc:`create
-your own drivers <creating_drivers>`.

-##############################
-Handling Multiple Environments
-##############################
-
-Developers often desire different system behavior depending on whether
-an application is running in a development or production environment.
-For example, verbose error output is something that would be useful
-while developing an application, but it may also pose a security issue
-when "live".
-
-The ENVIRONMENT Constant
-========================
-
-By default, CodeIgniter comes with the environment constant set to use
-the value provided in ``$_SERVER['CI_ENV']``, otherwise defaults to
-'development'. At the top of index.php, you will see::
-
-	define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');
-
-This server variable can be set in your .htaccess file, or Apache 
-config using `SetEnv <https://httpd.apache.org/docs/2.2/mod/mod_env.html#setenv>`_. 
-Alternative methods are available for nginx and other servers, or you can 
-remove this logic entirely and set the constant based on the server's IP address.
-
-In addition to affecting some basic framework behavior (see the next
-section), you may use this constant in your own development to
-differentiate between which environment you are running in.
-
-Effects On Default Framework Behavior
-=====================================
-
-There are some places in the CodeIgniter system where the ENVIRONMENT
-constant is used. This section describes how default framework behavior
-is affected.
-
-Error Reporting
----------------
-
-Setting the ENVIRONMENT constant to a value of 'development' will cause
-all PHP errors to be rendered to the browser when they occur.
-Conversely, setting the constant to 'production' will disable all error
-output. Disabling error reporting in production is a :doc:`good security
-practice <security>`.
-
-Configuration Files
--------------------
-
-Optionally, you can have CodeIgniter load environment-specific
-configuration files. This may be useful for managing things like
-differing API keys across multiple environments. This is described in
-more detail in the environment section of the :doc:`Config Class
-<../libraries/config>` documentation.

-##############
-Error Handling
-##############
-
-CodeIgniter lets you build error reporting into your applications using
-the functions described below. In addition, it has an error logging
-class that permits error and debugging messages to be saved as text
-files.
-
-.. note:: By default, CodeIgniter displays all PHP errors. You might
-	wish to change this behavior once your development is complete. You'll
-	find the error_reporting() function located at the top of your main
-	index.php file. Disabling error reporting will NOT prevent log files
-	from being written if there are errors.
-
-Unlike most systems in CodeIgniter, the error functions are simple
-procedural interfaces that are available globally throughout the
-application. This approach permits error messages to get triggered
-without having to worry about class/function scoping.
-
-CodeIgniter also returns a status code whenever a portion of the core
-calls ``exit()``. This exit status code is separate from the HTTP status
-code, and serves as a notice to other processes that may be watching of
-whether the script completed successfully, or if not, what kind of
-problem it encountered that caused it to abort. These values are
-defined in *application/config/constants.php*. While exit status codes
-are most useful in CLI settings, returning the proper code helps server
-software keep track of your scripts and the health of your application.
-
-The following functions let you generate errors:
-
-.. php:function:: show_error($message, $status_code, $heading = 'An Error Was Encountered')
-
-	:param	mixed	$message: Error message
-	:param	int	$status_code: HTTP Response status code
-	:param	string	$heading: Error page heading
-	:rtype:	void
-
-	This function will display the error message supplied to it using
-	the error template appropriate to your execution::
-
-		application/views/errors/html/error_general.php
-
-	or:
-
-		application/views/errors/cli/error_general.php
-
-	The optional parameter ``$status_code`` determines what HTTP status
-	code should be sent with the error. If ``$status_code`` is less
-	than 100, the HTTP status code will be set to 500, and the exit
-	status code will be set to ``$status_code + EXIT__AUTO_MIN``.
-	If that value is larger than ``EXIT__AUTO_MAX``, or if
-	``$status_code`` is 100 or higher, the exit status code will be set
-	to ``EXIT_ERROR``.
-	You can check in *application/config/constants.php* for more detail.
-
-.. php:function:: show_404($page = '', $log_error = TRUE)
-
-	:param	string	$page: URI string
-	:param	bool	$log_error: Whether to log the error
-	:rtype:	void
-
-	This function will display the 404 error message supplied to it
-	using the error template appropriate to your execution::
-
-		application/views/errors/html/error_404.php
-
-	or:
-
-		application/views/errors/cli/error_404.php
-
-	The function expects the string passed to it to be the file path to
-	the page that isn't found. The exit status code will be set to
-	``EXIT_UNKNOWN_FILE``.
-	Note that CodeIgniter automatically shows 404 messages if
-	controllers are not found.
-
-	CodeIgniter automatically logs any ``show_404()`` calls. Setting the
-	optional second parameter to FALSE will skip logging.
-
-.. php:function:: log_message($level, $message)
-
-	:param	string	$level: Log level: 'error', 'debug' or 'info'
-	:param	string	$message: Message to log
-	:rtype:	void
-
-	This function lets you write messages to your log files. You must
-	supply one of three "levels" in the first parameter, indicating what
-	type of message it is (debug, error, info), with the message itself
-	in the second parameter.
-
-	Example::
-
-		if ($some_var == '')
-		{
-			log_message('error', 'Some variable did not contain a value.');
-		}
-		else
-		{
-			log_message('debug', 'Some variable was correctly set');
-		}
-
-		log_message('info', 'The purpose of some variable is to provide some value.');
-
-	There are three message types:
-
-	#. Error Messages. These are actual errors, such as PHP errors or
-	   user errors.
-	#. Debug Messages. These are messages that assist in debugging. For
-	   example, if a class has been initialized, you could log this as
-	   debugging info.
-	#. Informational Messages. These are the lowest priority messages,
-	   simply giving information regarding some process.
-
-	.. note:: In order for the log file to actually be written, the
-		*logs/* directory must be writable. In addition, you must
-		set the "threshold" for logging in
-		*application/config/config.php*. You might, for example,
-		only want error messages to be logged, and not the other
-		two types. If you set it to zero logging will be disabled.

-Helper Functions
-################
-
-Helpers, as the name suggests, help you with tasks. Each helper file is
-simply a collection of functions in a particular category. There are **URL
-Helpers**, that assist in creating links, there are Form Helpers that help
-you create form elements, **Text Helpers** perform various text formatting
-routines, **Cookie Helpers** set and read cookies, File Helpers help you
-deal with files, etc.
-
-Unlike most other systems in CodeIgniter, Helpers are not written in an
-Object Oriented format. They are simple, procedural functions. Each
-helper function performs one specific task, with no dependence on other
-functions.
-
-CodeIgniter does not load Helper Files by default, so the first step in
-using a Helper is to load it. Once loaded, it becomes globally available
-in your :doc:`controller <../general/controllers>` and
-:doc:`views <../general/views>`.
-
-Helpers are typically stored in your **system/helpers**, or
-**application/helpers directory**. CodeIgniter will look first in your
-**application/helpers directory**. If the directory does not exist or the
-specified helper is not located there CI will instead look in your
-global *system/helpers/* directory.
-
-Loading a Helper
-================
-
-Loading a helper file is quite simple using the following method::
-
-	$this->load->helper('name');
-
-Where **name** is the file name of the helper, without the .php file
-extension or the "helper" part.
-
-For example, to load the **URL Helper** file, which is named
-**url_helper.php**, you would do this::
-
-	$this->load->helper('url');
-
-A helper can be loaded anywhere within your controller methods (or
-even within your View files, although that's not a good practice), as
-long as you load it before you use it. You can load your helpers in your
-controller constructor so that they become available automatically in
-any function, or you can load a helper in a specific function that needs
-it.
-
-.. note:: The Helper loading method above does not return a value, so
-	don't try to assign it to a variable. Just use it as shown.
-
-Loading Multiple Helpers
-========================
-
-If you need to load more than one helper you can specify them in an
-array, like this::
-
-	$this->load->helper(
-		array('helper1', 'helper2', 'helper3')
-	);
-
-Auto-loading Helpers
-====================
-
-If you find that you need a particular helper globally throughout your
-application, you can tell CodeIgniter to auto-load it during system
-initialization. This is done by opening the **application/config/autoload.php**
-file and adding the helper to the autoload array.
-
-Using a Helper
-==============
-
-Once you've loaded the Helper File containing the function you intend to
-use, you'll call it the way you would a standard PHP function.
-
-For example, to create a link using the ``anchor()`` function in one of
-your view files you would do this::
-
-	<?php echo anchor('blog/comments', 'Click Here');?>
-
-Where "Click Here" is the name of the link, and "blog/comments" is the
-URI to the controller/method you wish to link to.
-
-"Extending" Helpers
-===================
-
-To "extend" Helpers, create a file in your **application/helpers/** folder
-with an identical name to the existing Helper, but prefixed with **MY\_**
-(this item is configurable. See below.).
-
-If all you need to do is add some functionality to an existing helper -
-perhaps add a function or two, or change how a particular helper
-function operates - then it's overkill to replace the entire helper with
-your version. In this case it's better to simply "extend" the Helper.
-
-.. note:: The term "extend" is used loosely since Helper functions are
-	procedural and discrete and cannot be extended in the traditional
-	programmatic sense. Under the hood, this gives you the ability to
-	add to or or to replace the functions a Helper provides.
-
-For example, to extend the native **Array Helper** you'll create a file
-named **application/helpers/MY_array_helper.php**, and add or override
-functions::
-
-	// any_in_array() is not in the Array Helper, so it defines a new function
-	function any_in_array($needle, $haystack)
-	{
-		$needle = is_array($needle) ? $needle : array($needle);
-
-		foreach ($needle as $item)
-		{
-			if (in_array($item, $haystack))
-			{
-				return TRUE;
-			}
-	        }
-
-		return FALSE;
-	}
-
-	// random_element() is included in Array Helper, so it overrides the native function
-	function random_element($array)
-	{
-		shuffle($array);
-		return array_pop($array);
-	}
-
-Setting Your Own Prefix
------------------------
-
-The filename prefix for "extending" Helpers is the same used to extend
-libraries and core classes. To set your own prefix, open your
-**application/config/config.php** file and look for this item::
-
-	$config['subclass_prefix'] = 'MY_';
-
-Please note that all native CodeIgniter libraries are prefixed with **CI\_**
-so DO NOT use that as your prefix.
-
-Now What?
-=========
-
-In the Table of Contents you'll find a list of all the available Helper
-Files. Browse each one to see what they do.

-####################################
-Hooks - Extending the Framework Core
-####################################
-
-CodeIgniter's Hooks feature provides a means to tap into and modify the
-inner workings of the framework without hacking the core files. When
-CodeIgniter runs it follows a specific execution process, diagramed in
-the :doc:`Application Flow <../overview/appflow>` page. There may be
-instances, however, where you'd like to cause some action to take place
-at a particular stage in the execution process. For example, you might
-want to run a script right before your controllers get loaded, or right
-after, or you might want to trigger one of your own scripts in some
-other location.
-
-Enabling Hooks
-==============
-
-The hooks feature can be globally enabled/disabled by setting the
-following item in the **application/config/config.php** file::
-
-	$config['enable_hooks'] = TRUE;
-
-Defining a Hook
-===============
-
-Hooks are defined in the **application/config/hooks.php** file.
-Each hook is specified as an array with this prototype::
-
-	$hook['pre_controller'] = array(
-		'class'    => 'MyClass',
-		'function' => 'Myfunction',
-		'filename' => 'Myclass.php',
-		'filepath' => 'hooks',
-		'params'   => array('beer', 'wine', 'snacks')
-	);
-
-**Notes:**
-
-The array index correlates to the name of the particular hook point you
-want to use. In the above example the hook point is pre_controller. A
-list of hook points is found below. The following items should be
-defined in your associative hook array:
-
--  **class** The name of the class you wish to invoke. If you prefer to
-   use a procedural function instead of a class, leave this item blank.
--  **function** The function (or method) name you wish to call.
--  **filename** The file name containing your class/function.
--  **filepath** The name of the directory containing your script.
-   Note:
-   Your script must be located in a directory INSIDE your *application/*
-   directory, so the file path is relative to that directory. For example,
-   if your script is located in *application/hooks/*, you will simply use
-   'hooks' as your filepath. If your script is located in
-   *application/hooks/utilities/* you will use 'hooks/utilities' as your
-   filepath. No trailing slash.
--  **params** Any parameters you wish to pass to your script. This item
-   is optional.
-
-You can also use lambda/anoymous functions (or closures) as hooks, with
-a simpler syntax::
-
-	$hook['post_controller'] = function()
-	{
-		/* do something here */
-	};
-
-Multiple Calls to the Same Hook
-===============================
-
-If want to use the same hook point with more than one script, simply
-make your array declaration multi-dimensional, like this::
-
-	$hook['pre_controller'][] = array(
-		'class'    => 'MyClass',
-		'function' => 'MyMethod',
-		'filename' => 'Myclass.php',
-		'filepath' => 'hooks',
-		'params'   => array('beer', 'wine', 'snacks')
-	);
-
-	$hook['pre_controller'][] = array(
-		'class'    => 'MyOtherClass',
-		'function' => 'MyOtherMethod',
-		'filename' => 'Myotherclass.php',
-		'filepath' => 'hooks',
-		'params'   => array('red', 'yellow', 'blue')
-	);
-
-Notice the brackets after each array index::
-
-	$hook['pre_controller'][]
-
-This permits you to have the same hook point with multiple scripts. The
-order you define your array will be the execution order.
-
-Hook Points
-===========
-
-The following is a list of available hook points.
-
--  **pre_system**
-   Called very early during system execution. Only the benchmark and
-   hooks class have been loaded at this point. No routing or other
-   processes have happened.
--  **pre_controller**
-   Called immediately prior to any of your controllers being called.
-   All base classes, routing, and security checks have been done.
--  **post_controller_constructor**
-   Called immediately after your controller is instantiated, but prior
-   to any method calls happening.
--  **post_controller**
-   Called immediately after your controller is fully executed.
--  **display_override**
-   Overrides the ``_display()`` method, used to send the finalized page
-   to the web browser at the end of system execution. This permits you
-   to use your own display methodology. Note that you will need to
-   reference the CI superobject with ``$this->CI =& get_instance()`` and
-   then the finalized data will be available by calling
-   ``$this->CI->output->get_output()``.
--  **cache_override**
-   Enables you to call your own method instead of the ``_display_cache()``
-   method in the :doc:`Output Library <../libraries/output>`. This permits
-   you to use your own cache display mechanism.
--  **post_system**
-   Called after the final rendered page is sent to the browser, at the
-   end of system execution after the finalized data is sent to the
-   browser.

-###########################
-Using CodeIgniter Libraries
-###########################
-
-All of the available libraries are located in your *system/libraries/*
-directory. In most cases, to use one of these classes involves initializing
-it within a :doc:`controller <controllers>` using the following
-initialization method::
-
-	$this->load->library('class_name');
-
-Where 'class_name' is the name of the class you want to invoke. For
-example, to load the :doc:`Form Validation Library
-<../libraries/form_validation>` you would do this::
-
-	$this->load->library('form_validation');
-
-Once initialized you can use it as indicated in the user guide page
-corresponding to that class.
-
-Additionally, multiple libraries can be loaded at the same time by
-passing an array of libraries to the load method.
-
-Example::
-
-	$this->load->library(array('email', 'table'));
-
-Creating Your Own Libraries
-===========================

-##########################
-Managing your Applications
-##########################
-
-By default it is assumed that you only intend to use CodeIgniter to
-manage one application, which you will build in your *application/*
-directory. It is possible, however, to have multiple sets of
-applications that share a single CodeIgniter installation, or even to
-rename or relocate your application directory.
-
-Renaming the Application Directory
-==================================
-
-If you would like to rename your application directory you may do so
-as long as you open your main index.php file and set its name using
-the ``$application_folder`` variable::
-
-	$application_folder = 'application';
-
-Relocating your Application Directory
-=====================================
-
-It is possible to move your application directory to a different
-location on your server than your web root. To do so open
-your main index.php and set a *full server path* in the
-``$application_folder`` variable::
-
-	$application_folder = '/path/to/your/application';
-
-Running Multiple Applications with one CodeIgniter Installation
-===============================================================
-
-If you would like to share a common CodeIgniter installation to manage
-several different applications simply put all of the directories located
-inside your application directory into their own sub-directory.
-
-For example, let's say you want to create two applications, named "foo"
-and "bar". You could structure your application directories like this::
-
-	applications/foo/
-	applications/foo/config/
-	applications/foo/controllers/
-	applications/foo/libraries/
-	applications/foo/models/
-	applications/foo/views/
-	applications/bar/
-	applications/bar/config/
-	applications/bar/controllers/
-	applications/bar/libraries/
-	applications/bar/models/
-	applications/bar/views/
-
-To select a particular application for use requires that you open your
-main index.php file and set the ``$application_folder`` variable. For
-example, to select the "foo" application for use you would do this::
-
-	$application_folder = 'applications/foo';
-
-.. note:: Each of your applications will need its own index.php file
-	which calls the desired application. The index.php file can be named
-	anything you want.

-Models
-######
-
-Models are **optionally** available for those who want to use a more
-traditional MVC approach.
-
-.. contents:: Page Contents
-
-What is a Model?
-================
-
-Models are PHP classes that are designed to work with information in
-your database. For example, let's say you use CodeIgniter to manage a
-blog. You might have a model class that contains functions to insert,
-update, and retrieve your blog data. Here is an example of what such a
-model class might look like::
-
-	class Blog_model extends CI_Model {
-
-		public $title;
-		public $content;
-		public $date;
-
-		public function get_last_ten_entries()
-		{
-			$query = $this->db->get('entries', 10);
-			return $query->result();
-		}
-
-		public function insert_entry()
-		{
-			$this->title	= $_POST['title']; // please read the below note
-			$this->content	= $_POST['content'];
-			$this->date	= time();
-
-			$this->db->insert('entries', $this);
-		}
-
-		public function update_entry()
-		{
-			$this->title	= $_POST['title'];
-			$this->content	= $_POST['content'];
-			$this->date	= time();
-
-			$this->db->update('entries', $this, array('id' => $_POST['id']));
-		}
-
-	}
-
-.. note:: The methods in the above example use the :doc:`Query Builder
-	<../database/query_builder>` database methods.
-
-.. note:: For the sake of simplicity in this example we're using ``$_POST``
-	directly. This is generally bad practice, and a more common approach
-	would be to use the :doc:`Input Library <../libraries/input>`
-	``$this->input->post('title')``.
-
-Anatomy of a Model
-==================
-
-Model classes are stored in your **application/models/** directory.
-They can be nested within sub-directories if you want this type of
-organization.
-
-The basic prototype for a model class is this::
-
-	class Model_name extends CI_Model {
-
-		public function __construct()
-		{
-			parent::__construct();
-			// Your own constructor code
-		}
-
-	}
-
-Where **Model_name** is the name of your class. Class names **must** have
-the first letter capitalized with the rest of the name lowercase. Make
-sure your class extends the base Model class.
-
-The file name must match the class name. For example, if this is your class::
-
-	class User_model extends CI_Model {
-
-		public function __construct()
-		{
-			parent::__construct();
-			// Your own constructor code
-		}
-
-	}
-
-Your file will be this::
-
-	application/models/User_model.php
-
-Loading a Model
-===============
-
-Your models will typically be loaded and called from within your
-:doc:`controller <controllers>` methods. To load a model you will use
-the following method::
-
-	$this->load->model('model_name');
-
-If your model is located in a sub-directory, include the relative path
-from your models directory. For example, if you have a model located at
-*application/models/blog/Queries.php* you'll load it using::
-
-	$this->load->model('blog/queries');
-
-Once loaded, you will access your model methods using an object with the
-same name as your class::
-
-	$this->load->model('model_name');
-
-	$this->model_name->method();
-
-If you would like your model assigned to a different object name you can
-specify it via the second parameter of the loading method::
-
-	$this->load->model('model_name', 'foobar');
-
-	$this->foobar->method();
-
-Here is an example of a controller, that loads a model, then serves a
-view::
-
-	class Blog_controller extends CI_Controller {
-
-		public function blog()
-		{
-			$this->load->model('blog');
-
-			$data['query'] = $this->blog->get_last_ten_entries();
-
-			$this->load->view('blog', $data);
-		}
-	}
-	
-
-Auto-loading Models
-===================
-
-If you find that you need a particular model globally throughout your
-application, you can tell CodeIgniter to auto-load it during system
-initialization. This is done by opening the
-**application/config/autoload.php** file and adding the model to the
-autoload array.
-
-Connecting to your Database
-===========================
-
-When a model is loaded it does **NOT** connect automatically to your
-database. The following options for connecting are available to you:
-
--  You can connect using the standard database methods :doc:`described
-   here <../database/connecting>`, either from within your
-   Controller class or your Model class.
--  You can tell the model loading method to auto-connect by passing
-   TRUE (boolean) via the third parameter, and connectivity settings,
-   as defined in your database config file will be used::
-
-	$this->load->model('model_name', '', TRUE);
-
--  You can manually pass database connectivity settings via the third
-   parameter::
-
-	$config['hostname'] = 'localhost';
-	$config['username'] = 'myusername';
-	$config['password'] = 'mypassword';
-	$config['database'] = 'mydatabase';
-	$config['dbdriver'] = 'mysqli';
-	$config['dbprefix'] = '';
-	$config['pconnect'] = FALSE;
-	$config['db_debug'] = TRUE;
-
-	$this->load->model('model_name', '', $config);

-##########################
-Profiling Your Application
-##########################
-
-The Profiler Class will display benchmark results, queries you have run,
-and ``$_POST`` data at the bottom of your pages. This information can be
-useful during development in order to help with debugging and
-optimization.
-
-Initializing the Class
-======================
-
-.. important:: This class does NOT need to be initialized. It is loaded
-	automatically by the :doc:`Output Library <../libraries/output>`
-	if profiling is enabled as shown below.
-
-Enabling the Profiler
-=====================
-
-To enable the profiler place the following line anywhere within your
-:doc:`Controller <controllers>` methods::
-
-	$this->output->enable_profiler(TRUE);
-
-When enabled a report will be generated and inserted at the bottom of
-your pages.
-
-To disable the profiler you will use::
-
-	$this->output->enable_profiler(FALSE);
-
-Setting Benchmark Points
-========================
-
-In order for the Profiler to compile and display your benchmark data you
-must name your mark points using specific syntax.
-
-Please read the information on setting Benchmark points in the
-:doc:`Benchmark Library <../libraries/benchmark>` page.
-
-Enabling and Disabling Profiler Sections
-========================================
-
-Each section of Profiler data can be enabled or disabled by setting a
-corresponding config variable to TRUE or FALSE. This can be done one of
-two ways. First, you can set application wide defaults with the
-*application/config/profiler.php* config file.
-
-Example::
-
-	$config['config']          = FALSE;
-	$config['queries']         = FALSE;
-
-In your controllers, you can override the defaults and config file
-values by calling the ``set_profiler_sections()`` method of the
-:doc:`Output Library <../libraries/output>`::
-
-	$sections = array(
-		'config'  => TRUE,
-		'queries' => TRUE
-	);
-
-	$this->output->set_profiler_sections($sections);
-
-Available sections and the array key used to access them are described
-in the table below.

-                        hidden.
-======================= =================================================================== ========
-
-.. note:: Disabling the :doc:`save_queries </database/configuration>` setting in
-	your database configuration will also effectively disable profiling for
-	database queries and render the 'queries' setting above useless. You can
-	optionally override this setting with ``$this->db->save_queries = TRUE;``.
-	Without this setting you won't be able to view the queries or the
-	`last_query <database/helpers>`.

-###########
-URI Routing
-###########
-
-Typically there is a one-to-one relationship between a URL string and
-its corresponding controller class/method. The segments in a URI
-normally follow this pattern::
-
-	example.com/class/function/id/
-
-In some instances, however, you may want to remap this relationship so
-that a different class/method can be called instead of the one
-corresponding to the URL.
-
-For example, let's say you want your URLs to have this prototype::
-
-	example.com/product/1/
-	example.com/product/2/
-	example.com/product/3/
-	example.com/product/4/
-
-Normally the second segment of the URL is reserved for the method
-name, but in the example above it instead has a product ID. To
-overcome this, CodeIgniter allows you to remap the URI handler.
-
-Setting your own routing rules
-==============================
-
-Routing rules are defined in your *application/config/routes.php* file.
-In it you'll see an array called ``$route`` that permits you to specify
-your own routing criteria. Routes can either be specified using wildcards
-or Regular Expressions.
-
-Wildcards
-=========
-
-A typical wildcard route might look something like this::
-
-	$route['product/:num'] = 'catalog/product_lookup';
-
-In a route, the array key contains the URI to be matched, while the
-array value contains the destination it should be re-routed to. In the
-above example, if the literal word "product" is found in the first
-segment of the URL, and a number is found in the second segment, the
-"catalog" class and the "product_lookup" method are instead used.
-
-You can match literal values or you can use two wildcard types:
-
-**(:num)** will match a segment containing only numbers.
-**(:any)** will match a segment containing any character (except for '/', which is the segment delimiter).
-
-.. note:: Wildcards are actually aliases for regular expressions, with
-	**:any** being translated to **[^/]+** and **:num** to **[0-9]+**,
-	respectively.
-
-.. note:: Routes will run in the order they are defined. Higher routes
-	will always take precedence over lower ones.
-
-.. note:: Route rules are not filters! Setting a rule of e.g.
-	'foo/bar/(:num)' will not prevent controller *Foo* and method
-	*bar* to be called with a non-numeric value if that is a valid
-	route.
-
-Examples
-========
-
-Here are a few routing examples::
-
-	$route['journals'] = 'blogs';
-
-A URL containing the word "journals" in the first segment will be
-remapped to the "blogs" class.
-
-::
-
-	$route['blog/joe'] = 'blogs/users/34';
-
-A URL containing the segments blog/joe will be remapped to the "blogs"
-class and the "users" method. The ID will be set to "34".
-
-::
-
-	$route['product/(:any)'] = 'catalog/product_lookup';
-
-A URL with "product" as the first segment, and anything in the second
-will be remapped to the "catalog" class and the "product_lookup"
-method.
-
-::
-
-	$route['product/(:num)'] = 'catalog/product_lookup_by_id/$1';
-
-A URL with "product" as the first segment, and a number in the second
-will be remapped to the "catalog" class and the
-"product_lookup_by_id" method passing in the match as a variable to
-the method.
-
-.. important:: Do not use leading/trailing slashes.
-
-Regular Expressions
-===================
-
-If you prefer you can use regular expressions to define your routing
-rules. Any valid regular expression is allowed, as are back-references.
-
-.. note:: If you use back-references you must use the dollar syntax
-	rather than the double backslash syntax.
-
-A typical RegEx route might look something like this::
-
-	$route['products/([a-z]+)/(\d+)'] = '$1/id_$2';
-
-In the above example, a URI similar to products/shirts/123 would instead
-call the "shirts" controller class and the "id_123" method.
-
-With regular expressions, you can also catch multiple segments at once.
-For example, if a user accesses a password protected area of your web
-application and you wish to be able to redirect them back to the same
-page after they log in, you may find this example useful::
-
-	$route['login/(.+)'] = 'auth/login/$1';
-
-.. note:: In the above example, if the ``$1`` placeholder contains a
-	slash, it will still be split into multiple parameters when
-	passed to ``Auth::login()``.
-
-For those of you who don't know regular expressions and want to learn
-more about them, `regular-expressions.info <http://www.regular-expressions.info/>`_
-might be a good starting point.
-
-.. note:: You can also mix and match wildcards with regular expressions.
-
-Callbacks
-=========
-
-You can also use callbacks in place of the normal routing rules to process
-the back-references. Example::
-
-	$route['products/([a-zA-Z]+)/edit/(\d+)'] = function ($product_type, $id)
-	{
-		return 'catalog/product_edit/' . strtolower($product_type) . '/' . $id;
-	};
-
-Using HTTP verbs in routes
-==========================
-
-It is possible to use HTTP verbs (request method) to define your routing rules.
-This is particularly useful when building RESTful applications. You can use standard HTTP
-verbs (GET, PUT, POST, DELETE, PATCH) or a custom one such (e.g. PURGE). HTTP verb rules
-are case-insensitive. All you need to do is to add the verb as an array key to your route.
-Example::
-
-	$route['products']['put'] = 'product/insert';
-
-In the above example, a PUT request to URI "products" would call the ``Product::insert()``
-controller method.
-
-::
-
-	$route['products/(:num)']['DELETE'] = 'product/delete/$1';
-
-A DELETE request to URL with "products" as first the segment and a number in the second will be
-mapped to the ``Product::delete()`` method, passing the numeric value as the first parameter.
-
-Using HTTP verbs is of course, optional.
-
-Reserved Routes
-===============
-
-There are three reserved routes::
-
-	$route['default_controller'] = 'welcome';
-
-This route points to the action that should be executed if the URI contains
-no data, which will be the case when people load your root URL.
-The setting accepts a **controller/method** value and ``index()`` would be
-the default method if you don't specify one. In the above example, it is
-``Welcome::index()`` that would be called.
-
-.. note:: You can NOT use a directory as a part of this setting!
-
-You are encouraged to always have a default route as otherwise a 404 page
-will appear by default.
-
-::
-
-	$route['404_override'] = '';
-
-This route indicates which controller class should be loaded if the
-requested controller is not found. It will override the default 404
-error page. Same per-directory rules as with 'default_controller'
-apply here as well.
-
-It won't affect to the ``show_404()`` function, which will
-continue loading the default *error_404.php* file at
-*application/views/errors/error_404.php*.
-
-::
-
-	$route['translate_uri_dashes'] = FALSE;
-
-As evident by the boolean value, this is not exactly a route. This
-option enables you to automatically replace dashes ('-') with
-underscores in the controller and method URI segments, thus saving you
-additional route entries if you need to do that.
-This is required, because the dash isn't a valid class or method name
-character and would cause a fatal error if you try to use it.

-########
-Security
-########
-
-This page describes some "best practices" regarding web security, and
-details CodeIgniter's internal security features.
-
-.. note:: If you came here looking for a security contact, please refer to
-	our `Contribution Guide <../contributing/index>`.
-
-URI Security
-============
-
-CodeIgniter is fairly restrictive regarding which characters it allows
-in your URI strings in order to help minimize the possibility that
-malicious data can be passed to your application. URIs may only contain
-the following:
-
--  Alpha-numeric text (latin characters only)
--  Tilde: ~
--  Percent sign: %
--  Period: .
--  Colon: :
--  Underscore: \_
--  Dash: -
--  Space
-
-Register_globals
-================
-
-During system initialization all global variables that are found to exist
-in the ``$_GET``, ``$_POST``, ``$_REQUEST`` and ``$_COOKIE`` are unset.
-
-The unsetting routine is effectively the same as *register_globals = off*.
-
-display_errors
-==============
-
-In production environments, it is typically desirable to "disable" PHP's
-error reporting by setting the internal *display_errors* flag to a value
-of 0. This disables native PHP errors from being rendered as output,
-which may potentially contain sensitive information.
-
-Setting CodeIgniter's **ENVIRONMENT** constant in index.php to a value of
-**\'production\'** will turn off these errors. In development mode, it is
-recommended that a value of 'development' is used. More information
-about differentiating between environments can be found on the
-:doc:`Handling Environments <environments>` page.
-
-magic_quotes_runtime
-====================
-
-The *magic_quotes_runtime* directive is turned off during system
-initialization so that you don't have to remove slashes when retrieving
-data from your database.
-
-**************
-Best Practices
-**************
-
-Before accepting any data into your application, whether it be POST data
-from a form submission, COOKIE data, URI data, XML-RPC data, or even
-data from the SERVER array, you are encouraged to practice this three
-step approach:
-
-#. Validate the data to ensure it conforms to the correct type, length,
-   size, etc.
-#. Filter the data as if it were tainted.
-#. Escape the data before submitting it into your database or outputting
-   it to a browser.
-
-CodeIgniter provides the following functions and tips to assist you
-in this process:
-
-XSS Filtering
-=============
-
-CodeIgniter comes with a Cross Site Scripting filter. This filter
-looks for commonly used techniques to embed malicious JavaScript into
-your data, or other types of code that attempt to hijack cookies or
-do other malicious things. The XSS Filter is described
-:doc:`here <../libraries/security>`.
-
-.. note:: XSS filtering should *only be performed on output*. Filtering
-	input data may modify the data in undesirable ways, including
-	stripping special characters from passwords, which reduces
-	security instead of improving it.
-
-CSRF protection
-===============
-
-CSRF stands for Cross-Site Request Forgery, which is the process of an
-attacker tricking their victim into unknowingly submitting a request.
-
-CodeIgniter provides CSRF protection out of the box, which will get
-automatically triggered for every non-GET HTTP request, but also needs
-you to create your submit forms in a certain way. This is explained in
-the :doc:`Security Library <../libraries/security>` documentation.
-
-Password handling
-=================
-
-It is *critical* that you handle passwords in your application properly.
-
-Unfortunately, many developers don't know how to do that, and the web is
-full of outdated or otherwise wrongful advices, which doesn't help.
-
-We would like to give you a list of combined do's and don'ts to help you
-with that. Please read below.
-
--  DO NOT store passwords in plain-text format.
-
-   Always **hash** your passwords.
-
--  DO NOT use Base64 or similar encoding for storing passwords.
-
-   This is as good as storing them in plain-text. Really. Do **hashing**,
-   not *encoding*.
-
-   Encoding, and encryption too, are two-way processes. Passwords are
-   secrets that must only be known to their owner, and thus must work
-   only in one direction. Hashing does that - there's *no* un-hashing or
-   de-hashing, but there is decoding and decryption.
-
--  DO NOT use weak or broken hashing algorithms like MD5 or SHA1.
-
-   These algorithms are old, proven to be flawed, and not designed for
-   password hashing in the first place.
-
-   Also, DON'T invent your own algorithms.
-
-   Only use strong password hashing algorithms like BCrypt, which is used
-   in PHP's own `Password Hashing <http://php.net/password>`_ functions.
-
-   Please use them, even if you're not running PHP 5.5+, CodeIgniter
-   provides them for you.
-
--  DO NOT ever display or send a password in plain-text format!
-
-   Even to the password's owner, if you need a "Forgotten password"
-   feature, just randomly generate a new, one-time (this is also important)
-   password and send that instead.
-
--  DO NOT put unnecessary limits on your users' passwords.
-
-   If you're using a hashing algorithm other than BCrypt (which has a limit
-   of 72 characters), you should set a relatively high limit on password
-   lengths in order to mitigate DoS attacks - say, 1024 characters.
-
-   Other than that however, there's no point in forcing a rule that a
-   password can only be up to a number of characters, or that it can't
-   contain a certain set of special characters.
-
-   Not only does this **reduce** security instead of improving it, but
-   there's literally no reason to do it. No technical limitations and
-   no (practical) storage constraints apply once you've hashed them, none!
-
-Validate input data
-===================
-
-CodeIgniter has a :doc:`Form Validation Library
-<../libraries/form_validation>` that assists you in
-validating, filtering, and prepping your data.
-
-Even if that doesn't work for your use case however, be sure to always
-validate and sanitize all input data. For example, if you expect a numeric
-string for an input variable, you can check for that with ``is_numeric()``
-or ``ctype_digit()``. Always try to narrow down your checks to a certain
-pattern.
-
-Have it in mind that this includes not only ``$_POST`` and ``$_GET``
-variables, but also cookies, the user-agent string and basically
-*all data that is not created directly by your own code*.
-
-
-Escape all data before database insertion
-=========================================
-
-Never insert information into your database without escaping it.
-Please see the section that discusses :doc:`database queries
-<../database/queries>` for more information.
-
-Hide your files
-===============
-
-Another good security practice is to only leave your *index.php*
-and "assets" (e.g. .js, css and image files) under your server's
-*webroot* directory (most commonly named "htdocs/"). These are
-the only files that you would need to be accessible from the web.
-
-Allowing your visitors to see anything else would potentially
-allow them to access sensitive data, execute scripts, etc.
-
-If you're not allowed to do that, you can try using a .htaccess
-file to restrict access to those resources.
-
-CodeIgniter will have an index.html file in all of its
-directories in an attempt to hide some of this data, but have
-it in mind that this is not enough to prevent a serious
-attacker.

-###############
-PHP Style Guide
-###############
-
-
-The following page describes the coding styles adhered to when
-contributing to the development of CodeIgniter. There is no requirement
-to use these styles in your own CodeIgniter application, though they
-are recommended.
-
-.. contents:: Table of Contents
-
-File Format
-===========
-
-Files should be saved with Unicode (UTF-8) encoding. The BOM should
-*not* be used. Unlike UTF-16 and UTF-32, there's no byte order to
-indicate in a UTF-8 encoded file, and the BOM can have a negative side
-effect in PHP of sending output, preventing the application from being
-able to set its own headers. Unix line endings should be used (LF).
-
-Here is how to apply these settings in some of the more common text
-editors. Instructions for your text editor may vary; check your text
-editor's documentation.
-
-TextMate
-''''''''
-
-#. Open the Application Preferences
-#. Click Advanced, and then the "Saving" tab
-#. In "File Encoding", select "UTF-8 (recommended)"
-#. In "Line Endings", select "LF (recommended)"
-#. *Optional:* Check "Use for existing files as well" if you wish to
-   modify the line endings of files you open to your new preference.
-
-BBEdit
-''''''
-
-#. Open the Application Preferences
-#. Select "Text Encodings" on the left.
-#. In "Default text encoding for new documents", select "Unicode (UTF-8,
-   no BOM)"
-#. *Optional:* In "If file's encoding can't be guessed, use", select
-   "Unicode (UTF-8, no BOM)"
-#. Select "Text Files" on the left.
-#. In "Default line breaks", select "Mac OS X and Unix (LF)"
-
-PHP Closing Tag
-===============
-
-The PHP closing tag on a PHP document **?>** is optional to the PHP
-parser. However, if used, any whitespace following the closing tag,
-whether introduced by the developer, user, or an FTP application, can
-cause unwanted output, PHP errors, or if the latter are suppressed,
-blank pages. For this reason, all PHP files MUST OMIT the PHP closing
-tag and end with a single empty line instead.
-
-File Naming
-===========
-
-Class files must be named in a Ucfirst-like manner, while any other file name
-(configurations, views, generic scripts, etc.) should be in all lowercase.
-
-**INCORRECT**::
-
-	somelibrary.php
-	someLibrary.php
-	SOMELIBRARY.php
-	Some_Library.php
-
-	Application_config.php
-	Application_Config.php
-	applicationConfig.php
-
-**CORRECT**::
-
-	Somelibrary.php
-	Some_library.php
-
-	applicationconfig.php
-	application_config.php
-
-Furthermore, class file names should match the name of the class itself.
-For example, if you have a class named `Myclass`, then its filename must
-be **Myclass.php**.
-
-Class and Method Naming
-=======================
-
-Class names should always start with an uppercase letter. Multiple words
-should be separated with an underscore, and not CamelCased.
-
-**INCORRECT**::
-
-	class superclass
-	class SuperClass
-
-**CORRECT**::
-
-	class Super_class
-
-::
-
-	class Super_class {
-
-		public function __construct()
-		{
-
-		}
-	}
-
-Class methods should be entirely lowercased and named to clearly
-indicate their function, preferably including a verb. Try to avoid
-overly long and verbose names. Multiple words should be separated
-with an underscore.
-
-**INCORRECT**::
-
-	function fileproperties()		// not descriptive and needs underscore separator
-	function fileProperties()		// not descriptive and uses CamelCase
-	function getfileproperties()		// Better!  But still missing underscore separator
-	function getFileProperties()		// uses CamelCase
-	function get_the_file_properties_from_the_file()	// wordy
-
-**CORRECT**::
-
-	function get_file_properties()	// descriptive, underscore separator, and all lowercase letters
-
-Variable Names
-==============
-
-The guidelines for variable naming are very similar to those used for
-class methods. Variables should contain only lowercase letters,
-use underscore separators, and be reasonably named to indicate their
-purpose and contents. Very short, non-word variables should only be used
-as iterators in for() loops.
-
-**INCORRECT**::
-
-	$j = 'foo';		// single letter variables should only be used in for() loops
-	$Str			// contains uppercase letters
-	$bufferedText		// uses CamelCasing, and could be shortened without losing semantic meaning
-	$groupid		// multiple words, needs underscore separator
-	$name_of_last_city_used	// too long
-
-**CORRECT**::
-
-	for ($j = 0; $j < 10; $j++)
-	$str
-	$buffer
-	$group_id
-	$last_city
-
-Commenting
-==========
-
-In general, code should be commented prolifically. It not only helps
-describe the flow and intent of the code for less experienced
-programmers, but can prove invaluable when returning to your own code
-months down the line. There is not a required format for comments, but
-the following are recommended.
-
-`DocBlock <http://manual.phpdoc.org/HTMLSmartyConverter/HandS/phpDocumentor/tutorial_phpDocumentor.howto.pkg.html#basics.docblock>`_
-style comments preceding class, method, and property declarations so they can be
-picked up by IDEs::
-
-	/**
-	 * Super Class
-	 *
-	 * @package	Package Name
-	 * @subpackage	Subpackage
-	 * @category	Category
-	 * @author	Author Name
-	 * @link	http://example.com
-	 */
-	class Super_class {
-
-::
-
-	/**
-	 * Encodes string for use in XML
-	 *
-	 * @param	string	$str	Input string
-	 * @return	string
-	 */
-	function xml_encode($str)
-
-::
-
-	/**
-	 * Data for class manipulation
-	 *
-	 * @var	array
-	 */
-	public $data = array();
-
-Use single line comments within code, leaving a blank line between large
-comment blocks and code.
-
-::
-
-	// break up the string by newlines
-	$parts = explode("\n", $str);
-
-	// A longer comment that needs to give greater detail on what is
-	// occurring and why can use multiple single-line comments.  Try to
-	// keep the width reasonable, around 70 characters is the easiest to
-	// read.  Don't hesitate to link to permanent external resources
-	// that may provide greater detail:
-	//
-	// http://example.com/information_about_something/in_particular/
-
-	$parts = $this->foo($parts);
-
-Constants
-=========
-
-Constants follow the same guidelines as do variables, except constants
-should always be fully uppercase. *Always use CodeIgniter constants when
-appropriate, i.e. SLASH, LD, RD, PATH_CACHE, etc.*
-
-**INCORRECT**::
-
-	myConstant	// missing underscore separator and not fully uppercase
-	N		// no single-letter constants
-	S_C_VER		// not descriptive
-	$str = str_replace('{foo}', 'bar', $str);	// should use LD and RD constants
-
-**CORRECT**::
-
-	MY_CONSTANT
-	NEWLINE
-	SUPER_CLASS_VERSION
-	$str = str_replace(LD.'foo'.RD, 'bar', $str);
-
-TRUE, FALSE, and NULL
-=====================
-
-**TRUE**, **FALSE**, and **NULL** keywords should always be fully
-uppercase.
-
-**INCORRECT**::
-
-	if ($foo == true)
-	$bar = false;
-	function foo($bar = null)
-
-**CORRECT**::
-
-	if ($foo == TRUE)
-	$bar = FALSE;
-	function foo($bar = NULL)
-
-Logical Operators
-=================
-
-Use of the ``||`` "or" comparison operator is discouraged, as its clarity
-on some output devices is low (looking like the number 11, for instance).
-``&&`` is preferred over ``AND`` but either are acceptable, and a space should
-always precede and follow ``!``.
-
-**INCORRECT**::
-
-	if ($foo || $bar)
-	if ($foo AND $bar)  // okay but not recommended for common syntax highlighting applications
-	if (!$foo)
-	if (! is_array($foo))
-
-**CORRECT**::
-
-	if ($foo OR $bar)
-	if ($foo && $bar) // recommended
-	if ( ! $foo)
-	if ( ! is_array($foo))
-	
-
-Comparing Return Values and Typecasting
-=======================================
-
-Some PHP functions return FALSE on failure, but may also have a valid
-return value of "" or 0, which would evaluate to FALSE in loose
-comparisons. Be explicit by comparing the variable type when using these
-return values in conditionals to ensure the return value is indeed what
-you expect, and not a value that has an equivalent loose-type
-evaluation.
-
-Use the same stringency in returning and checking your own variables.
-Use **===** and **!==** as necessary.
-
-**INCORRECT**::
-
-	// If 'foo' is at the beginning of the string, strpos will return a 0,
-	// resulting in this conditional evaluating as TRUE
-	if (strpos($str, 'foo') == FALSE)
-
-**CORRECT**::
-
-	if (strpos($str, 'foo') === FALSE)
-
-**INCORRECT**::
-
-	function build_string($str = "")
-	{
-		if ($str == "")	// uh-oh!  What if FALSE or the integer 0 is passed as an argument?
-		{
-
-		}
-	}
-
-**CORRECT**::
-
-	function build_string($str = "")
-	{
-		if ($str === "")
-		{
-
-		}
-	}
-
-
-See also information regarding `typecasting
-<http://php.net/manual/en/language.types.type-juggling.php#language.types.typecasting>`_,
-which can be quite useful. Typecasting has a slightly different effect
-which may be desirable. When casting a variable as a string, for
-instance, NULL and boolean FALSE variables become empty strings, 0 (and
-other numbers) become strings of digits, and boolean TRUE becomes "1"::
-
-	$str = (string) $str; // cast $str as a string
-
-Debugging Code
-==============
-
-Do not leave debugging code in your submissions, even when commented out.
-Things such as ``var_dump()``, ``print_r()``, ``die()``/``exit()`` should not be included
-in your code unless it serves a specific purpose other than debugging.
-
-Whitespace in Files
-===================
-
-No whitespace can precede the opening PHP tag or follow the closing PHP
-tag. Output is buffered, so whitespace in your files can cause output to
-begin before CodeIgniter outputs its content, leading to errors and an
-inability for CodeIgniter to send proper headers.
-
-Compatibility
-=============
-
-CodeIgniter recommends PHP 5.6 or newer to be used, but it should be
-compatible with PHP 5.3.7. Your code must either be compatible with this
-requirement, provide a suitable fallback, or be an optional feature that
-dies quietly without affecting a user's application.
-
-Additionally, do not use PHP functions that require non-default libraries
-to be installed unless your code contains an alternative method when the
-function is not available.
-
-One File per Class
-==================
-
-Use separate files for each class, unless the classes are *closely related*.
-An example of a CodeIgniter file that contains multiple classes is the 
-Xmlrpc library file.
-
-Whitespace
-==========
-
-Use tabs for whitespace in your code, not spaces. This may seem like a
-small thing, but using tabs instead of whitespace allows the developer
-looking at your code to have indentation at levels that they prefer and
-customize in whatever application they use. And as a side benefit, it
-results in (slightly) more compact files, storing one tab character
-versus, say, four space characters.
-
-Line Breaks
-===========
-
-Files must be saved with Unix line breaks. This is more of an issue for
-developers who work in Windows, but in any case ensure that your text
-editor is setup to save files with Unix line breaks.
-
-Code Indenting
-==============
-
-Use Allman style indenting. With the exception of Class declarations,
-braces are always placed on a line by themselves, and indented at the
-same level as the control statement that "owns" them.
-
-**INCORRECT**::
-
-	function foo($bar) {
-		// ...
-	}
-
-	foreach ($arr as $key => $val) {
-		// ...
-	}
-
-	if ($foo == $bar) {
-		// ...
-	} else {
-		// ...
-	}
-
-	for ($i = 0; $i < 10; $i++)
-		{
-		for ($j = 0; $j < 10; $j++)
-			{
-			// ...
-			}
-		}
-		
-	try {
-		// ...
-	}
-	catch() {
-		// ...
-	}
-
-**CORRECT**::
-
-	function foo($bar)
-	{
-		// ...
-	}
-
-	foreach ($arr as $key => $val)
-	{
-		// ...
-	}
-
-	if ($foo == $bar)
-	{
-		// ...
-	}
-	else
-	{
-		// ...
-	}
-
-	for ($i = 0; $i < 10; $i++)
-	{
-		for ($j = 0; $j < 10; $j++)
-		{
-			// ...
-		}
-	}
-	
-	try 
-	{
-		// ...
-	}
-	catch()
-	{
-		// ...
-	}
-
-Bracket and Parenthetic Spacing
-===============================
-
-In general, parenthesis and brackets should not use any additional
-spaces. The exception is that a space should always follow PHP control
-structures that accept arguments with parenthesis (declare, do-while,
-elseif, for, foreach, if, switch, while), to help distinguish them from
-functions and increase readability.
-
-**INCORRECT**::
-
-	$arr[ $foo ] = 'foo';
-
-**CORRECT**::
-
-	$arr[$foo] = 'foo'; // no spaces around array keys
-
-**INCORRECT**::
-
-	function foo ( $bar )
-	{
-
-	}
-
-**CORRECT**::
-
-	function foo($bar) // no spaces around parenthesis in function declarations
-	{
-
-	}
-
-**INCORRECT**::
-
-	foreach( $query->result() as $row )
-
-**CORRECT**::
-
-	foreach ($query->result() as $row) // single space following PHP control structures, but not in interior parenthesis
-
-Localized Text
-==============
-
-CodeIgniter libraries should take advantage of corresponding language files
-whenever possible.
-
-**INCORRECT**::
-
-	return "Invalid Selection";
-
-**CORRECT**::
-
-	return $this->lang->line('invalid_selection');
-
-Private Methods and Variables
-=============================
-
-Methods and variables that are only accessed internally,
-such as utility and helper functions that your public methods use for
-code abstraction, should be prefixed with an underscore.
-
-::
-
-	public function convert_text()
-	private function _convert_text()
-
-PHP Errors
-==========
-
-Code must run error free and not rely on warnings and notices to be
-hidden to meet this requirement. For instance, never access a variable
-that you did not set yourself (such as ``$_POST`` array keys) without first
-checking to see that it ``isset()``.
-
-Make sure that your dev environment has error reporting enabled
-for ALL users, and that display_errors is enabled in the PHP
-environment. You can check this setting with::
-
-	if (ini_get('display_errors') == 1)
-	{
-		exit "Enabled";
-	}
-
-On some servers where *display_errors* is disabled, and you do not have
-the ability to change this in the php.ini, you can often enable it with::
-
-	ini_set('display_errors', 1);
-
-.. note:: Setting the `display_errors
-	<http://php.net/manual/en/errorfunc.configuration.php#ini.display-errors>`_
-	setting with ``ini_set()`` at runtime is not identical to having
-	it enabled in the PHP environment. Namely, it will not have any
-	effect if the script has fatal errors.
-
-Short Open Tags
-===============
-
-Always use full PHP opening tags, in case a server does not have
-*short_open_tag* enabled.
-
-**INCORRECT**::
-
-	<? echo $foo; ?>
-
-	<?=$foo?>
-
-**CORRECT**::
-
-	<?php echo $foo; ?>
-
-.. note:: PHP 5.4 will always have the **<?=** tag available.
-
-One Statement Per Line
-======================
-
-Never combine statements on one line.
-
-**INCORRECT**::
-
-	$foo = 'this'; $bar = 'that'; $bat = str_replace($foo, $bar, $bag);
-
-**CORRECT**::
-
-	$foo = 'this';
-	$bar = 'that';
-	$bat = str_replace($foo, $bar, $bag);
-
-Strings
-=======
-
-Always use single quoted strings unless you need variables parsed, and
-in cases where you do need variables parsed, use braces to prevent
-greedy token parsing. You may also use double-quoted strings if the
-string contains single quotes, so you do not have to use escape
-characters.
-
-**INCORRECT**::
-
-	"My String"					// no variable parsing, so no use for double quotes
-	"My string $foo"				// needs braces
-	'SELECT foo FROM bar WHERE baz = \'bag\''	// ugly
-
-**CORRECT**::
-
-	'My String'
-	"My string {$foo}"
-	"SELECT foo FROM bar WHERE baz = 'bag'"
-
-SQL Queries
-===========
-
-SQL keywords are always capitalized: SELECT, INSERT, UPDATE, WHERE,
-AS, JOIN, ON, IN, etc.
-
-Break up long queries into multiple lines for legibility, preferably
-breaking for each clause.
-
-**INCORRECT**::
-
-	// keywords are lowercase and query is too long for
-	// a single line (... indicates continuation of line)
-	$query = $this->db->query("select foo, bar, baz, foofoo, foobar as raboof, foobaz from exp_pre_email_addresses
-	...where foo != 'oof' and baz != 'zab' order by foobaz limit 5, 100");
-
-**CORRECT**::
-
-	$query = $this->db->query("SELECT foo, bar, baz, foofoo, foobar AS raboof, foobaz
-					FROM exp_pre_email_addresses
-					WHERE foo != 'oof'
-					AND baz != 'zab'
-					ORDER BY foobaz
-					LIMIT 5, 100");
-
-Default Function Arguments
-==========================
-
-Whenever appropriate, provide function argument defaults, which helps
-prevent PHP errors with mistaken calls and provides common fallback
-values which can save a few lines of code. Example::
-
-	function foo($bar = '', $baz = FALSE)

-################
-CodeIgniter URLs
-################
-
-By default, URLs in CodeIgniter are designed to be search-engine and
-human friendly. Rather than using the standard "query string" approach
-to URLs that is synonymous with dynamic systems, CodeIgniter uses a
-**segment-based** approach::
-
-	example.com/news/article/my_article
-
-.. note:: Query string URLs can be optionally enabled, as described
-	below.
-
-URI Segments
-============
-
-The segments in the URL, in following with the Model-View-Controller
-approach, usually represent::
-
-	example.com/class/function/ID
-
-#. The first segment represents the controller **class** that should be
-   invoked.
-#. The second segment represents the class **function**, or method, that
-   should be called.
-#. The third, and any additional segments, represent the ID and any
-   variables that will be passed to the controller.
-
-The :doc:`URI Library <../libraries/uri>` and the :doc:`URL Helper
-<../helpers/url_helper>` contain functions that make it easy to work
-with your URI data. In addition, your URLs can be remapped using the
-:doc:`URI Routing <routing>` feature for more flexibility.
-
-Removing the index.php file
-===========================
-
-By default, the **index.php** file will be included in your URLs::
-
-	example.com/index.php/news/article/my_article
-
-If your Apache server has *mod_rewrite* enabled, you can easily remove this
-file by using a .htaccess file with some simple rules. Here is an example
-of such a file, using the "negative" method in which everything is redirected
-except the specified items:
-
-::
-	
-	RewriteEngine On
-	RewriteCond %{REQUEST_FILENAME} !-f
-	RewriteCond %{REQUEST_FILENAME} !-d
-	RewriteRule ^(.*)$ index.php/$1 [L]
-
-In the above example, any HTTP request other than those for existing
-directories and existing files is treated as a request for your index.php file.
-
-.. note:: These specific rules might not work for all server configurations.
-
-.. note:: Make sure to also exclude from the above rule any assets that you
-	might need to be accessible from the outside world.
-
-Adding a URL Suffix
-===================
-
-In your **config/config.php** file you can specify a suffix that will be
-added to all URLs generated by CodeIgniter. For example, if a URL is
-this::
-
-	example.com/index.php/products/view/shoes
-
-You can optionally add a suffix, like **.html,** making the page appear to
-be of a certain type::
-
-	example.com/index.php/products/view/shoes.html
-
-Enabling Query Strings
-======================
-
-In some cases you might prefer to use query strings URLs::
-
-	index.php?c=products&m=view&id=345
-
-CodeIgniter optionally supports this capability, which can be enabled in
-your **application/config.php** file. If you open your config file you'll
-see these items::
-
-	$config['enable_query_strings'] = FALSE;
-	$config['controller_trigger'] = 'c';
-	$config['function_trigger'] = 'm';
-
-If you change "enable_query_strings" to TRUE this feature will become
-active. Your controllers and functions will then be accessible using the
-"trigger" words you've set to invoke your controllers and methods::
-
-	index.php?c=controller&m=method
-
-.. note:: If you are using query strings you will have to build your own
-	URLs, rather than utilizing the URL helpers (and other helpers
-	that generate URLs, like some of the form helpers) as these are
-	designed to work with segment based URLs.

-#####
-Views
-#####
-
-A view is simply a web page, or a page fragment, like a header, footer,
-sidebar, etc. In fact, views can flexibly be embedded within other views
-(within other views, etc., etc.) if you need this type of hierarchy.
-
-Views are never called directly, they must be loaded by a
-:doc:`controller <controllers>`. Remember that in an MVC framework, the
-Controller acts as the traffic cop, so it is responsible for fetching a
-particular view. If you have not read the
-:doc:`Controllers <controllers>` page you should do so before
-continuing.
-
-Using the example controller you created in the
-:doc:`controller <controllers>` page, let's add a view to it.
-
-Creating a View
-===============
-
-Using your text editor, create a file called blogview.php, and put this
-in it::
-
-	<html>
-	<head>
-		<title>My Blog</title>
-	</head>
-	<body>
-		<h1>Welcome to my Blog!</h1>
-	</body>
-	</html>
-	
-Then save the file in your *application/views/* directory.
-
-Loading a View
-==============
-
-To load a particular view file you will use the following method::
-
-	$this->load->view('name');
-
-Where name is the name of your view file.
-
-.. note:: The .php file extension does not need to be specified
-	unless you use something other than .php.
-
-Now, open the controller file you made earlier called Blog.php, and
-replace the echo statement with the view loading method::
-
-	<?php
-	class Blog extends CI_Controller {
-
-		public function index()
-		{
-			$this->load->view('blogview');
-		}
-	}
-
-If you visit your site using the URL you did earlier you should see your
-new view. The URL was similar to this::
-
-	example.com/index.php/blog/
-
-Loading multiple views
-======================
-
-CodeIgniter will intelligently handle multiple calls to
-``$this->load->view()`` from within a controller. If more than one call
-happens they will be appended together. For example, you may wish to
-have a header view, a menu view, a content view, and a footer view. That
-might look something like this::
-
-	<?php
-
-	class Page extends CI_Controller {
-
-		public function index()
-		{
-			$data['page_title'] = 'Your title';
-			$this->load->view('header');
-			$this->load->view('menu');
-			$this->load->view('content', $data);
-			$this->load->view('footer');
-		}
-
-	}
-
-In the example above, we are using "dynamically added data", which you
-will see below.
-
-Storing Views within Sub-directories
-====================================
-
-Your view files can also be stored within sub-directories if you prefer
-that type of organization. When doing so you will need to include the
-directory name loading the view. Example::
-
-	$this->load->view('directory_name/file_name');
-
-Adding Dynamic Data to the View
-===============================
-
-Data is passed from the controller to the view by way of an **array** or
-an **object** in the second parameter of the view loading method. Here
-is an example using an array::
-
-	$data = array(
-		'title' => 'My Title',
-		'heading' => 'My Heading',
-		'message' => 'My Message'
-	);
-
-	$this->load->view('blogview', $data);
-
-And here's an example using an object::
-
-	$data = new Someclass();
-	$this->load->view('blogview', $data);
-
-.. note:: If you use an object, the class variables will be turned
-	into array elements.
-
-Let's try it with your controller file. Open it add this code::
-
-	<?php
-	class Blog extends CI_Controller {
-
-		public function index()
-		{
-			$data['title'] = "My Real Title";
-			$data['heading'] = "My Real Heading";
-
-			$this->load->view('blogview', $data);
-		}
-	}
-
-Now open your view file and change the text to variables that correspond
-to the array keys in your data::
-
-	<html>
-	<head>
-		<title><?php echo $title;?></title>
-	</head>
-	<body>
-		<h1><?php echo $heading;?></h1>
-	</body>
-	</html>
-
-Then load the page at the URL you've been using and you should see the
-variables replaced.
-
-Creating Loops
-==============
-
-The data array you pass to your view files is not limited to simple
-variables. You can pass multi dimensional arrays, which can be looped to
-generate multiple rows. For example, if you pull data from your database
-it will typically be in the form of a multi-dimensional array.
-
-Here's a simple example. Add this to your controller::
-
-	<?php
-	class Blog extends CI_Controller {
-
-		public function index()
-		{
-			$data['todo_list'] = array('Clean House', 'Call Mom', 'Run Errands');
-
-			$data['title'] = "My Real Title";
-			$data['heading'] = "My Real Heading";
-
-			$this->load->view('blogview', $data);
-		}
-	}
-
-Now open your view file and create a loop::
-
-	<html>
-	<head>
-		<title><?php echo $title;?></title>
-	</head>
-	<body>
-		<h1><?php echo $heading;?></h1>
-	
-		<h3>My Todo List</h3>
-
-		<ul>
-		<?php foreach ($todo_list as $item):?>
-	
-			<li><?php echo $item;?></li>
-	
-		<?php endforeach;?>
-		</ul>
-
-	</body>
-	</html>
-
-.. note:: You'll notice that in the example above we are using PHP's
-	alternative syntax. If you are not familiar with it you can read about
-	it :doc:`here <alternative_php>`.
-
-Returning views as data
-=======================
-
-There is a third **optional** parameter lets you change the behavior of
-the method so that it returns data as a string rather than sending it
-to your browser. This can be useful if you want to process the data in
-some way. If you set the parameter to TRUE (boolean) it will return
-data. The default behavior is false, which sends it to your browser.
-Remember to assign it to a variable if you want the data returned::
-
-	$string = $this->load->view('myfile', '', TRUE);

-Array Helper
-############
-
-The Array Helper file contains functions that assist in working with
-arrays.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('array');
-
-
-Available Functions
-===================
-
-The following functions are available:
-
-
-.. php:function:: element($item, $array[, $default = NULL])
-
-	:param	string	$item: Item to fetch from the array
-	:param	array	$array: Input array
-	:param	bool	$default: What to return if the array isn't valid
-	:returns:	NULL on failure or the array item.
-	:rtype:	mixed
-
-	Lets you fetch an item from an array. The function tests whether the
-	array index is set and whether it has a value. If a value exists it is
-	returned. If a value does not exist it returns NULL, or whatever you've
-	specified as the default value via the third parameter.
-
-	Example::
-
-		$array = array(
-			'color'	=> 'red',
-			'shape'	=> 'round',
-			'size'	=> ''
-		);
-
-		echo element('color', $array); // returns "red"
-		echo element('size', $array, 'foobar'); // returns "foobar"
-
-
-.. php:function:: elements($items, $array[, $default = NULL])
-
-	:param	string	$item: Item to fetch from the array
-	:param	array	$array: Input array
-	:param	bool	$default: What to return if the array isn't valid
-	:returns:	NULL on failure or the array item.
-	:rtype:	mixed
-
-	Lets you fetch a number of items from an array. The function tests
-	whether each of the array indices is set. If an index does not exist it
-	is set to NULL, or whatever you've specified as the default value via
-	the third parameter.
-
-	Example::
-
-		$array = array(
-			'color' => 'red',
-			'shape' => 'round',
-			'radius' => '10',
-			'diameter' => '20'
-		);
-
-		$my_shape = elements(array('color', 'shape', 'height'), $array);
-
-	The above will return the following array::
-
-		array(
-			'color' => 'red',
-			'shape' => 'round',
-			'height' => NULL
-		);
-
-	You can set the third parameter to any default value you like.
-	::
-
-		 $my_shape = elements(array('color', 'shape', 'height'), $array, 'foobar');
-
-	The above will return the following array::
-
-		array(     
-			'color' 	=> 'red',
-			'shape' 	=> 'round',
-			'height'	=> 'foobar'
-		);
-
-	This is useful when sending the ``$_POST`` array to one of your Models.
-	This prevents users from sending additional POST data to be entered into
-	your tables.
-
-	::
-
-		$this->load->model('post_model');
-		$this->post_model->update(
-			elements(array('id', 'title', 'content'), $_POST)
-		);
-
-	This ensures that only the id, title and content fields are sent to be
-	updated.
-
-
-.. php:function:: random_element($array)
-
-	:param	array	$array: Input array
-	:returns:	A random element from the array
-	:rtype:	mixed
-
-	Takes an array as input and returns a random element from it.
-
-	Usage example::
-
-		$quotes = array(
-			"I find that the harder I work, the more luck I seem to have. - Thomas Jefferson",
-			"Don't stay in bed, unless you can make money in bed. - George Burns",
-			"We didn't lose the game; we just ran out of time. - Vince Lombardi",
-			"If everything seems under control, you're not going fast enough. - Mario Andretti",
-			"Reality is merely an illusion, albeit a very persistent one. - Albert Einstein",
-			"Chance favors the prepared mind - Louis Pasteur"
-		);
-
-		echo random_element($quotes);

-The CAPTCHA Helper file contains functions that assist in creating
-CAPTCHA images.

-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('captcha');
-
-Using the CAPTCHA helper
-========================
-
-Once loaded you can generate a CAPTCHA like this::
-
-	$vals = array(
-		'word'		=> 'Random word',
-		'img_path'	=> './captcha/',
-		'img_url'	=> 'http://example.com/captcha/',
-		'font_path'	=> './path/to/fonts/texb.ttf',
-		'img_width'	=> '150',
-		'img_height'	=> 30,
-		'expiration'	=> 7200,
-		'word_length'	=> 8,
-		'font_size'	=> 16,
-		'img_id'	=> 'Imageid',
-		'pool'		=> '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ',
-
-		// White background and border, black text and red grid
-		'colors'	=> array(
-			'background' => array(255, 255, 255),
-			'border' => array(255, 255, 255),
-			'text' => array(0, 0, 0),
-			'grid' => array(255, 40, 40)
-		)
-	);
-
-	$cap = create_captcha($vals);
-	echo $cap['image'];
-
--  The captcha function requires the GD image library.
--  Only the **img_path** and **img_url** are required.
--  If a **word** is not supplied, the function will generate a random
-   ASCII string. You might put together your own word library that you
-   can draw randomly from.
--  If you do not specify a path to a TRUE TYPE font, the native ugly GD
-   font will be used.
--  The "captcha" directory must be writable
--  The **expiration** (in seconds) signifies how long an image will remain
-   in the captcha folder before it will be deleted. The default is two
-   hours.
--  **word_length** defaults to 8, **pool** defaults to '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
--  **font_size** defaults to 16, the native GD font has a size limit. Specify a "true type" font for bigger sizes.
--  The **img_id** will be set as the "id" of the captcha image.
--  If any of the **colors** values is missing, it will be replaced by the default.
-
-Adding a Database
------------------
-
-In order for the captcha function to prevent someone from submitting,
-you will need to add the information returned from ``create_captcha()``
-to your database. Then, when the data from the form is submitted by
-the user you will need to verify that the data exists in the database
-and has not expired.
-
-Here is a table prototype::
-
-	CREATE TABLE captcha (  
-		captcha_id bigint(13) unsigned NOT NULL auto_increment,  
-		captcha_time int(10) unsigned NOT NULL,  
-		ip_address varchar(45) NOT NULL,  
-		word varchar(20) NOT NULL,  
-		PRIMARY KEY `captcha_id` (`captcha_id`),  
-		KEY `word` (`word`)
-	);
-
-Here is an example of usage with a database. On the page where the
-CAPTCHA will be shown you'll have something like this::
-
-	$this->load->helper('captcha');
-	$vals = array(     
-		'img_path'	=> './captcha/',     
-		'img_url'	=> 'http://example.com/captcha/'     
-	);
-
-	$cap = create_captcha($vals);
-	$data = array(     
-		'captcha_time'	=> $cap['time'],     
-		'ip_address'	=> $this->input->ip_address(),     
-		'word'		=> $cap['word']     
-	);
-
-	$query = $this->db->insert_string('captcha', $data);
-	$this->db->query($query);
-
-	echo 'Submit the word you see below:';
-	echo $cap['image'];
-	echo '<input type="text" name="captcha" value="" />';
-
-Then, on the page that accepts the submission you'll have something like
-this::
-
-	// First, delete old captchas
-	$expiration = time() - 7200; // Two hour limit
-	$this->db->where('captcha_time < ', $expiration)
-		->delete('captcha');
-
-	// Then see if a captcha exists:
-	$sql = 'SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND captcha_time > ?';
-	$binds = array($_POST['captcha'], $this->input->ip_address(), $expiration);
-	$query = $this->db->query($sql, $binds);
-	$row = $query->row();
-
-	if ($row->count == 0)
-	{     
-		echo 'You must submit the word that appears in the image.';
-	}
-
-Available Functions
-===================
-
-The following functions are available:
-
-.. php:function:: create_captcha([$data = ''[, $img_path = ''[, $img_url = ''[, $font_path = '']]]])
-
-	:param	array	$data: Array of data for the CAPTCHA
-	:param	string	$img_path: Path to create the image in
-	:param	string	$img_url: URL to the CAPTCHA image folder
-	:param	string	$font_path: Server path to font
-	:returns:	array('word' => $word, 'time' => $now, 'image' => $img)
-	:rtype:	array
-
-	Takes an array of information to generate the CAPTCHA as input and
-	creates the image to your specifications, returning an array of
-	associative data about the image.
-
-	::
-
-		array(
-			'image'	=> IMAGE TAG
-			'time'	=> TIMESTAMP (in microtime)
-			'word'	=> CAPTCHA WORD
-		)
-
-	The **image** is the actual image tag::
-
-		<img src="http://example.com/captcha/12345.jpg" width="140" height="50" />
-
-	The **time** is the micro timestamp used as the image name without the
-	file extension. It will be a number like this: 1139612155.3422
-
-	The **word** is the word that appears in the captcha image, which if not
-	supplied to the function, will be a random string.

-
-Available Functions
-===================
-
-The following functions are available:
-
-
-.. php:function:: set_cookie($name[, $value = ''[, $expire = ''[, $domain = ''[, $path = '/'[, $prefix = ''[, $secure = NULL[, $httponly = NULL]]]]]]])
-
-	:param	mixed	$name: Cookie name *or* associative array of all of the parameters available to this function
-	:param	string	$value: Cookie value
-	:param	int	$expire: Number of seconds until expiration
-	:param	string	$domain: Cookie domain (usually: .yourdomain.com)
-	:param	string	$path: Cookie path
-	:param	string	$prefix: Cookie name prefix
-	:param	bool	$secure: Whether to only send the cookie through HTTPS
-	:param	bool	$httponly: Whether to hide the cookie from JavaScript
-	:rtype:	void
-
-	This helper function gives you friendlier syntax to set browser
-	cookies. Refer to the :doc:`Input Library <../libraries/input>` for
-	a description of its use, as this function is an alias for
-	``CI_Input::set_cookie()``.
-
-.. php:function:: get_cookie($index[, $xss_clean = NULL])
-
-	:param	string	$index: Cookie name
-	:param	bool	$xss_clean: Whether to apply XSS filtering to the returned value
-	:returns:	The cookie value or NULL if not found
-	:rtype:	mixed
-
-	This helper function gives you friendlier syntax to get browser
-	cookies. Refer to the :doc:`Input Library <../libraries/input>` for
-	detailed description of its use, as this function acts very
-	similarly to ``CI_Input::cookie()``, except it will also prepend
-	the ``$config['cookie_prefix']`` that you might've set in your
-	*application/config/config.php* file.
-
-.. php:function:: delete_cookie($name[, $domain = ''[, $path = '/'[, $prefix = '']]])
-
-	:param	string	$name: Cookie name
-	:param	string	$domain: Cookie domain (usually: .yourdomain.com)
-	:param	string	$path: Cookie path
-	:param	string	$prefix: Cookie name prefix
-	:rtype:	void
-
-	Lets you delete a cookie. Unless you've set a custom path or other
-	values, only the name of the cookie is needed.
-	::
-
-		delete_cookie('name');
-
-	This function is otherwise identical to ``set_cookie()``, except that it
-	does not have the value and expiration parameters. You can submit an
-	array of values in the first parameter or you can set discrete
-	parameters.
-	::
-
-		delete_cookie($name, $domain, $path, $prefix);

-Date Helper
-###########
-
-The Date Helper file contains functions that help you work with dates.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('date');
-
-Available Functions
-===================
-
-The following functions are available:
-
-
-.. php:function:: now([$timezone = NULL])
-
-	:param	string	$timezone: Timezone
-	:returns:	UNIX timestamp
-	:rtype:	int
-
-	Returns the current time as a UNIX timestamp, referenced either to your server's
-	local time or any PHP supported timezone, based on the "time reference" setting
-	in your config file. If you do not intend to set your master time reference to
-	any other PHP supported timezone (which you'll typically do if you run a site
-	that lets each user set their own timezone settings) there is no benefit to using
-	this function over PHP's ``time()`` function.
-	::
-
-		echo now('Australia/Victoria');
-
-	If a timezone is not provided, it will return ``time()`` based on the
-	**time_reference** setting.
-
-.. php:function:: mdate([$datestr = ''[, $time = '']])
-
-	:param	string	$datestr: Date string
-	:param	int	$time: UNIX timestamp
-	:returns:	MySQL-formatted date
-	:rtype:	string
-
-	This function is identical to PHP's `date() <http://php.net/manual/en/function.date.php>`_
-	function, except that it lets you use MySQL style date codes, where each
-	code letter is preceded with a percent sign, e.g. `%Y %m %d`
-
-	The benefit of doing dates this way is that you don't have to worry
-	about escaping any characters that are not date codes, as you would
-	normally have to do with the ``date()`` function.
-
-	Example::
-
-		$datestring = 'Year: %Y Month: %m Day: %d - %h:%i %a';
-		$time = time();
-		echo mdate($datestring, $time);
-
-	If a timestamp is not included in the second parameter the current time
-	will be used.
-
-.. php:function:: standard_date([$fmt = 'DATE_RFC822'[, $time = NULL]])
-
-	:param	string	$fmt: Date format
-	:param	int	$time: UNIX timestamp
-	:returns:	Formatted date or FALSE on invalid format
-	:rtype:	string
-
-	Lets you generate a date string in one of several standardized formats.
-
-	Example::
-
-		$format = 'DATE_RFC822';
-		$time = time();
-		echo standard_date($format, $time);
-
-	.. note:: This function is DEPRECATED. Use the native ``date()`` combined with
-		`DateTime's format constants
-		<https://secure.php.net/manual/en/class.datetime.php#datetime.constants.types>`_
-		instead::
-
-			echo date(DATE_RFC822, time());
-
-	**Supported formats:**

-	===============	=======================	======================================
-
-.. php:function:: local_to_gmt([$time = ''])
-
-	:param	int	$time: UNIX timestamp
-	:returns:	UNIX timestamp
-	:rtype:	int
-
-	Takes a UNIX timestamp as input and returns it as GMT.
-
-	Example::
-
-		$gmt = local_to_gmt(time());
-
-.. php:function:: gmt_to_local([$time = ''[, $timezone = 'UTC'[, $dst = FALSE]]])
-
-	:param	int	$time: UNIX timestamp
-	:param	string	$timezone: Timezone
-	:param	bool	$dst: Whether DST is active
-	:returns:	UNIX timestamp
-	:rtype:	int
-
-	Takes a UNIX timestamp (referenced to GMT) as input, and converts it to
-	a localized timestamp based on the timezone and Daylight Saving Time
-	submitted.
-
-	Example::
-
-		$timestamp = 1140153693;
-		$timezone  = 'UM8';
-		$daylight_saving = TRUE;
-		echo gmt_to_local($timestamp, $timezone, $daylight_saving);
-
-
-	.. note:: For a list of timezones see the reference at the bottom of this page.
-
-.. php:function:: mysql_to_unix([$time = ''])
-
-	:param	string	$time: MySQL timestamp
-	:returns:	UNIX timestamp
-	:rtype:	int
-
-	Takes a MySQL Timestamp as input and returns it as a UNIX timestamp.
-
-	Example::
-
-		$unix = mysql_to_unix('20061124092345');
-
-.. php:function:: unix_to_human([$time = ''[, $seconds = FALSE[, $fmt = 'us']]])
-
-	:param	int	$time: UNIX timestamp
-	:param	bool	$seconds: Whether to show seconds
-	:param	string	$fmt: format (us or euro)
-	:returns:	Formatted date
-	:rtype:	string
-
-	Takes a UNIX timestamp as input and returns it in a human readable
-	format with this prototype::
-
-		YYYY-MM-DD HH:MM:SS AM/PM
-
-	This can be useful if you need to display a date in a form field for
-	submission.
-
-	The time can be formatted with or without seconds, and it can be set to
-	European or US format. If only the timestamp is submitted it will return
-	the time without seconds formatted for the U.S.
-
-	Examples::
-
-		$now = time();
-		echo unix_to_human($now); // U.S. time, no seconds
-		echo unix_to_human($now, TRUE, 'us'); // U.S. time with seconds
-		echo unix_to_human($now, TRUE, 'eu'); // Euro time with seconds
-
-.. php:function:: human_to_unix([$datestr = ''])
-
-	:param	int	$datestr: Date string
-	:returns:	UNIX timestamp or FALSE on failure
-	:rtype:	int
-
-	The opposite of the :php:func:`unix_to_time()` function. Takes a "human"
-	time as input and returns it as a UNIX timestamp. This is useful if you
-	accept "human" formatted dates submitted via a form. Returns boolean FALSE
-	date string passed to it is not formatted as indicated above.
-
-	Example::
-
-		$now = time();
-		$human = unix_to_human($now);
-		$unix = human_to_unix($human);
-
-.. php:function:: nice_date([$bad_date = ''[, $format = FALSE]])
-
-	:param	int	$bad_date: The terribly formatted date-like string
-	:param	string	$format: Date format to return (same as PHP's ``date()`` function)
-	:returns:	Formatted date
-	:rtype:	string
-
-	This function can take a number poorly-formed date formats and convert
-	them into something useful. It also accepts well-formed dates.
-
-	The function will return a UNIX timestamp by default. You can, optionally,
-	pass a format string (the same type as the PHP ``date()`` function accepts)
-	as the second parameter.
-
-	Example::
-
-		$bad_date = '199605';
-		// Should Produce: 1996-05-01
-		$better_date = nice_date($bad_date, 'Y-m-d');
-
-		$bad_date = '9-11-2001';
-		// Should Produce: 2001-09-11
-		$better_date = nice_date($bad_date, 'Y-m-d');
-
-	.. note:: This function is DEPRECATED. Use PHP's native `DateTime class
-		<https://secure.php.net/datetime>`_ instead.
-
-.. php:function:: timespan([$seconds = 1[, $time = ''[, $units = '']]])
-
-	:param	int	$seconds: Number of seconds
-	:param	string	$time: UNIX timestamp
-	:param	int	$units: Number of time units to display
-	:returns:	Formatted time difference
-	:rtype:	string
-
-	Formats a UNIX timestamp so that is appears similar to this::
-
-		1 Year, 10 Months, 2 Weeks, 5 Days, 10 Hours, 16 Minutes
-
-	The first parameter must contain a UNIX timestamp.
-	The second parameter must contain a timestamp that is greater that the
-	first timestamp.
-	The thirdparameter is optional and limits the number of time units to display.
-
-	If the second parameter empty, the current time will be used.
-
-	The most common purpose for this function is to show how much time has
-	elapsed from some point in time in the past to now.
-
-	Example::
-
-		$post_date = '1079621429';
-		$now = time();
-		$units = 2;
-		echo timespan($post_date, $now, $units);
-
-	.. note:: The text generated by this function is found in the following language
-		file: `language/<your_lang>/date_lang.php`
-
-.. php:function:: days_in_month([$month = 0[, $year = '']])
-
-	:param	int	$month: a numeric month
-	:param	int	$year: a numeric year
-	:returns:	Count of days in the specified month
-	:rtype:	int
-
-	Returns the number of days in a given month/year. Takes leap years into
-	account.
-
-	Example::
-
-		echo days_in_month(06, 2005);
-
-	If the second parameter is empty, the current year will be used.
-
-	.. note:: This function will alias the native ``cal_days_in_month()``, if
-		it is available.
-
-.. php:function:: date_range([$unix_start = ''[, $mixed = ''[, $is_unix = TRUE[, $format = 'Y-m-d']]]])
-
-	:param	int	$unix_start: UNIX timestamp of the range start date
-	:param	int	$mixed: UNIX timestamp of the range end date or interval in days
-	:param	bool	$is_unix: set to FALSE if $mixed is not a timestamp
-	:param	string	$format: Output date format, same as in ``date()``
-	:returns:	An array of dates
-	:rtype:	array
-
-	Returns a list of dates within a specified period.
-
-	Example::
-
-		$range = date_range('2012-01-01', '2012-01-15');
-		echo "First 15 days of 2012:";
-		foreach ($range as $date)
-		{
-			echo $date."\n";
-		}
-
-.. php:function:: timezones([$tz = ''])
-
-	:param	string	$tz: A numeric timezone
-	:returns:	Hour difference from UTC
-	:rtype:	int
-
-	Takes a timezone reference (for a list of valid timezones, see the
-	"Timezone Reference" below) and returns the number of hours offset from
-	UTC.
-
-	Example::
-
-		echo timezones('UM5');
-
-
-	This function is useful when used with :php:func:`timezone_menu()`.
-
-.. php:function:: timezone_menu([$default = 'UTC'[, $class = ''[, $name = 'timezones'[, $attributes = '']]]])
-
-	:param	string	$default: Timezone
-	:param	string	$class: Class name
-	:param	string	$name: Menu name
-	:param	mixed	$attributes: HTML attributes
-	:returns:	HTML drop down menu with time zones
-	:rtype:	string
-
-	Generates a pull-down menu of timezones, like this one:
-
-	.. raw:: html
-
-		<form action="#">
-			<select name="timezones">

-	This menu is useful if you run a membership site in which your users are
-	allowed to set their local timezone value.
-
-	The first parameter lets you set the "selected" state of the menu. For
-	example, to set Pacific time as the default you will do this::
-
-		echo timezone_menu('UM8');
-
-	Please see the timezone reference below to see the values of this menu.
-
-	The second parameter lets you set a CSS class name for the menu.
-
-	The fourth parameter lets you set one or more attributes on the generated select tag.
-
-	.. note:: The text contained in the menu is found in the following
-		language file: `language/<your_lang>/date_lang.php`

-Directory Helper
-################
-
-The Directory Helper file contains functions that assist in working with
-directories.
-
-.. contents::
-  :local:

-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-Loading this Helper
-===================
-
-This helper is loaded using the following code:
-
-::
-
-	$this->load->helper('directory');
-
-Available Functions
-===================
-
-The following functions are available:
-
-
-.. php:function:: directory_map($source_dir[, $directory_depth = 0[, $hidden = FALSE]])
-
-	:param	string	$source_dir: Path to the source directory
-	:param	int	$directory_depth: Depth of directories to traverse (0 = fully recursive, 1 = current dir, etc)
-	:param	bool	$hidden: Whether to include hidden directories
-	:returns:	An array of files
-	:rtype:	array
-
-	Examples::
-
-		$map = directory_map('./mydirectory/');
-
-	.. note:: Paths are almost always relative to your main index.php file.
-
-
-	Sub-folders contained within the directory will be mapped as well. If
-	you wish to control the recursion depth, you can do so using the second
-	parameter (integer). A depth of 1 will only map the top level directory::
-
-		$map = directory_map('./mydirectory/', 1);
-
-	By default, hidden files will not be included in the returned array. To
-	override this behavior, you may set a third parameter to true (boolean)::
-
-		$map = directory_map('./mydirectory/', FALSE, TRUE);
-
-	Each folder name will be an array index, while its contained files will
-	be numerically indexed. Here is an example of a typical array::
-
-		Array (
-			[libraries] => Array
-				(
-					[0] => benchmark.html
-					[1] => config.html
-					["database/"] => Array
-						(
-							[0] => query_builder.html

-	you want the downloaded file to be named**, the second parameter is the
-	file data.
-
-	If you set the second parameter to NULL and ``$filename`` is an existing, readable
-	file path, then its content will be read instead.
-
-	If you set the third parameter to boolean TRUE, then the actual file MIME type
-	(based on the filename extension) will be sent, so that if your browser has a
-	handler for that type - it can use it.
-
-	Example::
-
-		$data = 'Here is some text!';
-		$name = 'mytext.txt';
-		force_download($name, $data);
-
-	If you want to download an existing file from your server you'll need to

-
-The File Helper file contains functions that assist in working with files.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('file');
-
-Available Functions
-===================
-
-The following functions are available:
-
-
-.. php:function:: read_file($file)
-
-	:param	string	$file: File path
-	:returns:	File contents or FALSE on failure
-	:rtype:	string
-
-	Returns the data contained in the file specified in the path.
-
-	Example::
-
-		$string = read_file('./path/to/file.php');
-
-	The path can be a relative or full server path. Returns FALSE (boolean) on failure.
-
-	.. note:: The path is relative to your main site index.php file, NOT your
-		controller or view files. CodeIgniter uses a front controller so paths
-		are always relative to the main site index.
-
-	.. note:: This function is DEPRECATED. Use the native ``file_get_contents()``
-		instead.
-
-	.. important:: If your server is running an **open_basedir** restriction this
-		function might not work if you are trying to access a file above the
-		calling script.
-
-.. php:function:: write_file($path, $data[, $mode = 'wb'])
-
-	:param	string	$path: File path
-	:param	string	$data: Data to write to file
-	:param	string	$mode: ``fopen()`` mode
-	:returns:	TRUE if the write was successful, FALSE in case of an error
-	:rtype:	bool
-
-	Writes data to the file specified in the path. If the file does not exist then the
-	function will create it.
-
-	Example::
-
-		$data = 'Some file data';
-		if ( ! write_file('./path/to/file.php', $data))
-		{     
-			echo 'Unable to write the file';
-		}
-		else
-		{     
-			echo 'File written!';
-		}
-
-	You can optionally set the write mode via the third parameter::
-
-		write_file('./path/to/file.php', $data, 'r+');
-
-	The default mode is 'wb'. Please see the `PHP user guide <http://php.net/manual/en/function.fopen.php>`_
-	for mode options.
-
-	.. note: In order for this function to write data to a file, its permissions must
-		be set such that it is writable. If the file does not already exist,
-		then the directory containing it must be writable.
-
-	.. note:: The path is relative to your main site index.php file, NOT your
-		controller or view files. CodeIgniter uses a front controller so paths
-		are always relative to the main site index.
-
-	.. note:: This function acquires an exclusive lock on the file while writing to it.
-
-.. php:function:: delete_files($path[, $del_dir = FALSE[, $htdocs = FALSE]])
-
-	:param	string	$path: Directory path
-	:param	bool	$del_dir: Whether to also delete directories
-	:param	bool	$htdocs: Whether to skip deleting .htaccess and index page files
-	:returns:	TRUE on success, FALSE in case of an error
-	:rtype:	bool
-
-	Deletes ALL files contained in the supplied path.
-
-	Example::
-
-		delete_files('./path/to/directory/');
-
-	If the second parameter is set to TRUE, any directories contained within the supplied
-	root path will be deleted as well.
-
-	Example::
-
-		delete_files('./path/to/directory/', TRUE);
-
-	.. note:: The files must be writable or owned by the system in order to be deleted.
-
-.. php:function:: get_filenames($source_dir[, $include_path = FALSE])
-
-	:param	string	$source_dir: Directory path
-	:param	bool	$include_path: Whether to include the path as part of the filenames
-	:returns:	An array of file names
-	:rtype:	array
-
-	Takes a server path as input and returns an array containing the names of all files
-	contained within it. The file path can optionally be added to the file names by setting
-	the second parameter to TRUE.
-
-	Example::
-
-		$controllers = get_filenames(APPPATH.'controllers/');
-
-.. php:function:: get_dir_file_info($source_dir, $top_level_only)
-
-	:param	string	$source_dir: Directory path
-	:param	bool	$top_level_only: Whether to look only at the specified directory (excluding sub-directories)
-	:returns:	An array containing info on the supplied directory's contents
-	:rtype:	array
-
-	Reads the specified directory and builds an array containing the filenames, filesize,
-	dates, and permissions. Sub-folders contained within the specified path are only read
-	if forced by sending the second parameter to FALSE, as this can be an intensive
-	operation.
-
-	Example::
-
-		$models_info = get_dir_file_info(APPPATH.'models/');
-
-.. php:function:: get_file_info($file[, $returned_values = array('name', 'server_path', 'size', 'date')])
-
-	:param	string	$file: File path
-	:param	array	$returned_values: What type of info to return
-	:returns:	An array containing info on the specified file or FALSE on failure
-	:rtype:	array
-
-	Given a file and path, returns (optionally) the *name*, *path*, *size* and *date modified*
-	information attributes for a file. Second parameter allows you to explicitly declare what
-	information you want returned.
-
-	Valid ``$returned_values`` options are: `name`, `size`, `date`, `readable`, `writeable`,
-	`executable` and `fileperms`.
-
-.. php:function:: get_mime_by_extension($filename)
-
-	:param	string	$filename: File name
-	:returns:	MIME type string or FALSE on failure
-	:rtype:	string
-
-	Translates a filename extension into a MIME type based on *config/mimes.php*.
-	Returns FALSE if it can't determine the type, or read the MIME config file.
-
-	::
-
-		$file = 'somefile.png';
-		echo $file.' is has a mime type of '.get_mime_by_extension($file);
-
-	.. note:: This is not an accurate way of determining file MIME types, and
-		is here strictly for convenience. It should not be used for security
-		purposes.
-
-.. php:function:: symbolic_permissions($perms)
-
-	:param	int	$perms: Permissions
-	:returns:	Symbolic permissions string
-	:rtype:	string
-
-	Takes numeric permissions (such as is returned by ``fileperms()``) and returns
-	standard symbolic notation of file permissions.
-
-	::
-
-		echo symbolic_permissions(fileperms('./index.php'));  // -rw-r--r--
-
-.. php:function:: octal_permissions($perms)
-
-	:param	int	$perms: Permissions
-	:returns:	Octal permissions string
-	:rtype:	string
-
-	Takes numeric permissions (such as is returned by ``fileperms()``) and returns
-	a three character octal notation of file permissions.
-
-	::
-
-		echo octal_permissions(fileperms('./index.php')); // 644

-Form Helper
-###########
-
-The Form Helper file contains functions that assist in working with
-forms.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('form');
-
-Escaping field values
-=====================
-
-You may need to use HTML and characters such as quotes within your form
-elements. In order to do that safely, you'll need to use
-:doc:`common function <../general/common_functions>`
-:func:`html_escape()`.
-
-Consider the following example::
-
-	$string = 'Here is a string containing "quoted" text.';
-
-	<input type="text" name="myfield" value="<?php echo $string; ?>" />
-
-Since the above string contains a set of quotes, it will cause the form
-to break. The :php:func:`html_escape()` function converts HTML special
-characters so that it can be used safely::
-
-	<input type="text" name="myfield" value="<?php echo html_escape($string); ?>" />
-
-.. note:: If you use any of the form helper functions listed on this page,
-	the form values will be automatically escaped, so there is no need
-	to call this function. Use it only if you are creating your own
-	form elements.
-
-Available Functions
-===================
-
-The following functions are available:
-
-
-.. php:function:: form_open([$action = ''[, $attributes = ''[, $hidden = array()]]])
-
-	:param	string	$action: Form action/target URI string
-	:param	array	$attributes: HTML attributes
-	:param	array	$hidden: An array of hidden fields' definitions
-	:returns:	An HTML form opening tag
-	:rtype:	string
-
-	Creates an opening form tag with a base URL **built from your config preferences**.
-	It will optionally let you add form attributes and hidden input fields, and
-	will always add the `accept-charset` attribute based on the charset value in your
-	config file.
-
-	The main benefit of using this tag rather than hard coding your own HTML is that
-	it permits your site to be more portable in the event your URLs ever change.
-
-	Here's a simple example::
-
-		echo form_open('email/send');
-
-	The above example would create a form that points to your base URL plus the
-	"email/send" URI segments, like this::
-
-		<form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send">
-
-	**Adding Attributes**
-
-		Attributes can be added by passing an associative array to the second
-		parameter, like this::
-
-			$attributes = array('class' => 'email', 'id' => 'myform');
-			echo form_open('email/send', $attributes);
-
-		Alternatively, you can specify the second parameter as a string::
-
-			echo form_open('email/send', 'class="email" id="myform"');
-
-		The above examples would create a form similar to this::
-
-			<form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send" class="email" id="myform">
-
-	**Adding Hidden Input Fields**
-
-		Hidden fields can be added by passing an associative array to the
-		third parameter, like this::
-
-			$hidden = array('username' => 'Joe', 'member_id' => '234');
-			echo form_open('email/send', '', $hidden);
-
-		You can skip the second parameter by passing any falsy value to it.
-
-		The above example would create a form similar to this::
-
-			<form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send">
-				<input type="hidden" name="username" value="Joe" />
-				<input type="hidden" name="member_id" value="234" />
-
-
-.. php:function:: form_open_multipart([$action = ''[, $attributes = array()[, $hidden = array()]]])
-
-	:param	string	$action: Form action/target URI string
-	:param	array	$attributes: HTML attributes
-	:param	array	$hidden: An array of hidden fields' definitions
-	:returns:	An HTML multipart form opening tag
-	:rtype:	string
-
-	This function is absolutely identical to :php:func:`form_open()` above,
-	except that it adds a *multipart* attribute, which is necessary if you
-	would like to use the form to upload files with.
-
-
-.. php:function:: form_hidden($name[, $value = ''])
-
-	:param	string	$name: Field name
-	:param	string	$value: Field value
-	:returns:	An HTML hidden input field tag
-	:rtype:	string
-
-	Lets you generate hidden input fields. You can either submit a
-	name/value string to create one field::
-
-		form_hidden('username', 'johndoe');
-		// Would produce: <input type="hidden" name="username" value="johndoe" />
-
-	... or you can submit an associative array to create multiple fields::
-
-		$data = array(
-			'name'	=> 'John Doe',
-			'email'	=> 'john@example.com',
-			'url'	=> 'http://example.com'
-		);
-
-		echo form_hidden($data);
-
-		/*
-			Would produce:
-			<input type="hidden" name="name" value="John Doe" />
-			<input type="hidden" name="email" value="john@example.com" />
-			<input type="hidden" name="url" value="http://example.com" />
-		*/
-
-	You can also pass an associative array to the value field::
-
-		$data = array(
-			'name'	=> 'John Doe',
-			'email'	=> 'john@example.com',
-			'url'	=> 'http://example.com'
-		);
-

-			<input type="hidden" name="my_array[email]" value="john@example.com" />
-			<input type="hidden" name="my_array[url]" value="http://example.com" />
-		*/
-
-	If you want to create hidden input fields with extra attributes::
-
-		$data = array(
-			'type'	=> 'hidden',
-			'name'	=> 'email',
-			'id'	=> 'hiddenemail',
-			'value'	=> 'john@example.com',
-			'class'	=> 'hiddenemail'
-		);
-
-		echo form_input($data);
-
-		/*
-			Would produce:
-
-			<input type="hidden" name="email" value="john@example.com" id="hiddenemail" class="hiddenemail" />
-		*/
-
-.. php:function:: form_input([$data = ''[, $value = ''[, $extra = '']]])
-
-	:param	array	$data: Field attributes data
-	:param	string	$value: Field value
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML text input field tag
-	:rtype:	string
-
-	Lets you generate a standard text input field. You can minimally pass
-	the field name and value in the first and second parameter::
-
-		echo form_input('username', 'johndoe');
-
-	Or you can pass an associative array containing any data you wish your
-	form to contain::
-
-		$data = array(
-			'name'		=> 'username',
-			'id'		=> 'username',
-			'value'		=> 'johndoe',
-			'maxlength'	=> '100',
-			'size'		=> '50',
-			'style'		=> 'width:50%'
-		);
-
-		echo form_input($data);
-
-		/*
-			Would produce:
-
-			<input type="text" name="username" value="johndoe" id="username" maxlength="100" size="50" style="width:50%"  />
-		*/
-
-	If you would like your form to contain some additional data, like
-	JavaScript, you can pass it as a string in the third parameter::
-
-		$js = 'onClick="some_function()"';
-		echo form_input('username', 'johndoe', $js);
-
-	Or you can pass it as an array::
-
-		$js = array('onClick' => 'some_function();');
-		echo form_input('username', 'johndoe', $js);
-
-.. php:function:: form_password([$data = ''[, $value = ''[, $extra = '']]])
-
-	:param	array	$data: Field attributes data
-	:param	string	$value: Field value
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML password input field tag
-	:rtype:	string
-
-	This function is identical in all respects to the :php:func:`form_input()`
-	function above except that it uses the "password" input type.
-
-
-.. php:function:: form_upload([$data = ''[, $value = ''[, $extra = '']]])
-
-	:param	array	$data: Field attributes data
-	:param	string	$value: Field value
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML file upload input field tag
-	:rtype:	string
-
-	This function is identical in all respects to the :php:func:`form_input()`
-	function above except that it uses the "file" input type, allowing it to
-	be used to upload files.
-
-
-.. php:function:: form_textarea([$data = ''[, $value = ''[, $extra = '']]])
-
-	:param	array	$data: Field attributes data
-	:param	string	$value: Field value
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML textarea tag
-	:rtype:	string
-
-	This function is identical in all respects to the :php:func:`form_input()`
-	function above except that it generates a "textarea" type.
-
-	.. note:: Instead of the *maxlength* and *size* attributes in the above example,
-		you will instead specify *rows* and *cols*.
-
-.. php:function:: form_dropdown([$name = ''[, $options = array()[, $selected = array()[, $extra = '']]]])
-
-	:param	string	$name: Field name
-	:param	array	$options: An associative array of options to be listed
-	:param	array	$selected: List of fields to mark with the *selected* attribute
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML dropdown select field tag
-	:rtype:	string
-
-	Lets you create a standard drop-down field. The first parameter will
-	contain the name of the field, the second parameter will contain an
-	associative array of options, and the third parameter will contain the
-	value you wish to be selected. You can also pass an array of multiple
-	items through the third parameter, and CodeIgniter will create a
-	multiple select for you.
-
-	Example::
-
-		$options = array(
-			'small'		=> 'Small Shirt',
-			'med'		=> 'Medium Shirt',
-			'large'		=> 'Large Shirt',
-			'xlarge'	=> 'Extra Large Shirt',
-		);
-
-		$shirts_on_sale = array('small', 'large');
-		echo form_dropdown('shirts', $options, 'large');
-
-		/*
-			Would produce:
-
-			<select name="shirts">
-				<option value="small">Small Shirt</option>
-				<option value="med">Medium  Shirt</option>
-				<option value="large" selected="selected">Large Shirt</option>
-				<option value="xlarge">Extra Large Shirt</option>
-			</select>
-		*/
-
-		echo form_dropdown('shirts', $options, $shirts_on_sale);
-
-		/*
-			Would produce:
-
-			<select name="shirts" multiple="multiple">
-				<option value="small" selected="selected">Small Shirt</option>
-				<option value="med">Medium  Shirt</option>
-				<option value="large" selected="selected">Large Shirt</option>
-				<option value="xlarge">Extra Large Shirt</option>
-			</select>
-		*/
-
-	If you would like the opening <select> to contain additional data, like
-	an id attribute or JavaScript, you can pass it as a string in the fourth
-	parameter::
-
-		$js = 'id="shirts" onChange="some_function();"';
-		echo form_dropdown('shirts', $options, 'large', $js);
-
-	Or you can pass it as an array::
-
-		$js = array(
-			'id'       => 'shirts',
-			'onChange' => 'some_function();'
-		);
-		echo form_dropdown('shirts', $options, 'large', $js);
-
-	If the array passed as ``$options`` is a multidimensional array, then
-	``form_dropdown()`` will produce an <optgroup> with the array key as the
-	label.
-
-
-.. php:function:: form_multiselect([$name = ''[, $options = array()[, $selected = array()[, $extra = '']]]])
-
-	:param	string	$name: Field name
-	:param	array	$options: An associative array of options to be listed
-	:param	array	$selected: List of fields to mark with the *selected* attribute
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML dropdown multiselect field tag
-	:rtype:	string
-
-	Lets you create a standard multiselect field. The first parameter will
-	contain the name of the field, the second parameter will contain an
-	associative array of options, and the third parameter will contain the
-	value or values you wish to be selected.
-
-	The parameter usage is identical to using :php:func:`form_dropdown()` above,
-	except of course that the name of the field will need to use POST array
-	syntax, e.g. foo[].
-
-
-.. php:function:: form_fieldset([$legend_text = ''[, $attributes = array()]])
-
-	:param	string	$legend_text: Text to put in the <legend> tag
-	:param	array	$attributes: Attributes to be set on the <fieldset> tag
-	:returns:	An HTML fieldset opening tag
-	:rtype:	string
-
-	Lets you generate fieldset/legend fields.
-
-	Example::
-
-		echo form_fieldset('Address Information');
-		echo "<p>fieldset content here</p>\n";
-		echo form_fieldset_close();
-
-		/*
-			Produces:
-
-				<fieldset>
-					<legend>Address Information</legend>
-						<p>form content here</p>
-				</fieldset>
-		*/
-
-	Similar to other functions, you can submit an associative array in the
-	second parameter if you prefer to set additional attributes::
-
-		$attributes = array(
-			'id'	=> 'address_info',
-			'class'	=> 'address_info'
-		);
-
-		echo form_fieldset('Address Information', $attributes);
-		echo "<p>fieldset content here</p>\n";
-		echo form_fieldset_close();
-
-		/*
-			Produces:
-
-			<fieldset id="address_info" class="address_info">
-				<legend>Address Information</legend>
-				<p>form content here</p>
-			</fieldset>
-		*/
-
-
-.. php:function:: form_fieldset_close([$extra = ''])
-
-	:param	string	$extra: Anything to append after the closing tag, *as is*
-	:returns:	An HTML fieldset closing tag
-	:rtype:	string
-	
-
-	Produces a closing </fieldset> tag. The only advantage to using this
-	function is it permits you to pass data to it which will be added below
-	the tag. For example
-
-	::
-
-		$string = '</div></div>';
-		echo form_fieldset_close($string);
-		// Would produce: </fieldset></div></div>
-
-
-.. php:function:: form_checkbox([$data = ''[, $value = ''[, $checked = FALSE[, $extra = '']]]])
-
-	:param	array	$data: Field attributes data
-	:param	string	$value: Field value
-	:param	bool	$checked: Whether to mark the checkbox as being *checked*
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML checkbox input tag
-	:rtype:	string
-
-	Lets you generate a checkbox field. Simple example::
-
-		echo form_checkbox('newsletter', 'accept', TRUE);
-		// Would produce:  <input type="checkbox" name="newsletter" value="accept" checked="checked" />
-
-	The third parameter contains a boolean TRUE/FALSE to determine whether
-	the box should be checked or not.
-
-	Similar to the other form functions in this helper, you can also pass an
-	array of attributes to the function::
-
-		$data = array(
-			'name'		=> 'newsletter',
-			'id'		=> 'newsletter',
-			'value'		=> 'accept',
-			'checked'	=> TRUE,
-			'style'		=> 'margin:10px'
-		);
-
-		echo form_checkbox($data);
-		// Would produce: <input type="checkbox" name="newsletter" id="newsletter" value="accept" checked="checked" style="margin:10px" />
-
-	Also as with other functions, if you would like the tag to contain
-	additional data like JavaScript, you can pass it as a string in the
-	fourth parameter::
-
-		$js = 'onClick="some_function()"';
-		echo form_checkbox('newsletter', 'accept', TRUE, $js);
-
-	Or you can pass it as an array::
-
-		$js = array('onClick' => 'some_function();');
-		echo form_checkbox('newsletter', 'accept', TRUE, $js);
-
-
-.. php:function:: form_radio([$data = ''[, $value = ''[, $checked = FALSE[, $extra = '']]]])
-
-	:param	array	$data: Field attributes data
-	:param	string	$value: Field value
-	:param	bool	$checked: Whether to mark the radio button as being *checked*
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML radio input tag
-	:rtype:	string
-
-	This function is identical in all respects to the :php:func:`form_checkbox()`
-	function above except that it uses the "radio" input type.
-
-
-.. php:function:: form_label([$label_text = ''[, $id = ''[, $attributes = array()]]])
-
-	:param	string	$label_text: Text to put in the <label> tag
-	:param	string	$id: ID of the form element that we're making a label for
-	:param	mixed	$attributes: HTML attributes
-	:returns:	An HTML field label tag
-	:rtype:	string
-
-	Lets you generate a <label>. Simple example::
-
-		echo form_label('What is your Name', 'username');
-		// Would produce:  <label for="username">What is your Name</label>
-
-	Similar to other functions, you can submit an associative array in the
-	third parameter if you prefer to set additional attributes.
-
-	Example::
-
-		$attributes = array(
-			'class' => 'mycustomclass',
-			'style' => 'color: #000;'
-		);
-
-		echo form_label('What is your Name', 'username', $attributes);
-		// Would produce:  <label for="username" class="mycustomclass" style="color: #000;">What is your Name</label>
-
-
-.. php:function:: form_submit([$data = ''[, $value = ''[, $extra = '']]])
-
-	:param	string	$data: Button name
-	:param	string	$value: Button value
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML input submit tag
-	:rtype:	string
-
-	Lets you generate a standard submit button. Simple example::
-
-		echo form_submit('mysubmit', 'Submit Post!');
-		// Would produce:  <input type="submit" name="mysubmit" value="Submit Post!" />
-
-	Similar to other functions, you can submit an associative array in the
-	first parameter if you prefer to set your own attributes. The third
-	parameter lets you add extra data to your form, like JavaScript.
-
-
-.. php:function:: form_reset([$data = ''[, $value = ''[, $extra = '']]])
-
-	:param	string	$data: Button name
-	:param	string	$value: Button value
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML input reset button tag
-	:rtype:	string
-
-	Lets you generate a standard reset button. Use is identical to
-	:func:`form_submit()`.
-
-
-.. php:function:: form_button([$data = ''[, $content = ''[, $extra = '']]])
-
-	:param	string	$data: Button name
-	:param	string	$content: Button label
-	:param	mixed	$extra: Extra attributes to be added to the tag either as an array or a literal string
-	:returns:	An HTML button tag
-	:rtype:	string
-
-	Lets you generate a standard button element. You can minimally pass the
-	button name and content in the first and second parameter::
-
-		echo form_button('name','content');
-		// Would produce: <button name="name" type="button">Content</button>
-
-	Or you can pass an associative array containing any data you wish your
-	form to contain::
-
-		$data = array(
-			'name'		=> 'button',
-			'id'		=> 'button',
-			'value'		=> 'true',
-			'type'		=> 'reset',
-			'content'	=> 'Reset'
-		);
-
-		echo form_button($data);
-		// Would produce: <button name="button" id="button" value="true" type="reset">Reset</button>
-
-	If you would like your form to contain some additional data, like
-	JavaScript, you can pass it as a string in the third parameter::
-
-		$js = 'onClick="some_function()"';
-		echo form_button('mybutton', 'Click Me', $js);
-
-
-.. php:function:: form_close([$extra = ''])
-
-	:param	string	$extra: Anything to append after the closing tag, *as is*
-	:returns:	An HTML form closing tag
-	:rtype:	string
-
-	Produces a closing </form> tag. The only advantage to using this
-	function is it permits you to pass data to it which will be added below
-	the tag. For example::
-
-		$string = '</div></div>';
-		echo form_close($string);
-		// Would produce:  </form> </div></div>
-
-
-.. php:function:: set_value($field[, $default = ''[, $html_escape = TRUE]])
-
-	:param	string	$field: Field name
-	:param	string	$default: Default value
-	:param  bool	$html_escape: Whether to turn off HTML escaping of the value
-	:returns:	Field value
-	:rtype:	string
-
-	Permits you to set the value of an input form or textarea. You must
-	supply the field name via the first parameter of the function. The
-	second (optional) parameter allows you to set a default value for the
-	form. The third (optional) parameter allows you to turn off HTML escaping
-	of the value, in case you need to use this function in combination with
-	i.e. :php:func:`form_input()` and avoid double-escaping.
-
-	Example::
-
-		<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" />
-
-	The above form will show "0" when loaded for the first time.
-
-	.. note:: If you've loaded the :doc:`Form Validation Library <../libraries/form_validation>` and
-		have set a validation rule for the field name in use with this helper, then it will
-		forward the call to the :doc:`Form Validation Library <../libraries/form_validation>`'s
-		own ``set_value()`` method. Otherwise, this function looks in ``$_POST`` for the
-		field value.
-
-.. php:function:: set_select($field[, $value = ''[, $default = FALSE]])
-
-	:param	string	$field: Field name
-	:param	string	$value: Value to check for
-	:param	string	$default: Whether the value is also a default one
-	:returns:	'selected' attribute or an empty string
-	:rtype:	string
-
-	If you use a <select> menu, this function permits you to display the
-	menu item that was selected.
-
-	The first parameter must contain the name of the select menu, the second
-	parameter must contain the value of each item, and the third (optional)
-	parameter lets you set an item as the default (use boolean TRUE/FALSE).
-
-	Example::
-
-		<select name="myselect">
-			<option value="one" <?php echo  set_select('myselect', 'one', TRUE); ?> >One</option>
-			<option value="two" <?php echo  set_select('myselect', 'two'); ?> >Two</option>
-			<option value="three" <?php echo  set_select('myselect', 'three'); ?> >Three</option>
-		</select>
-
-.. php:function:: set_checkbox($field[, $value = ''[, $default = FALSE]])
-
-	:param	string	$field: Field name
-	:param	string	$value: Value to check for
-	:param	string	$default: Whether the value is also a default one
-	:returns:	'checked' attribute or an empty string
-	:rtype:	string
-
-	Permits you to display a checkbox in the state it was submitted.
-
-	The first parameter must contain the name of the checkbox, the second
-	parameter must contain its value, and the third (optional) parameter
-	lets you set an item as the default (use boolean TRUE/FALSE).
-
-	Example::
-
-		<input type="checkbox" name="mycheck" value="1" <?php echo set_checkbox('mycheck', '1'); ?> />
-		<input type="checkbox" name="mycheck" value="2" <?php echo set_checkbox('mycheck', '2'); ?> />
-
-.. php:function:: set_radio($field[, $value = ''[, $default = FALSE]])
-
-	:param	string	$field: Field name
-	:param	string	$value: Value to check for
-	:param	string	$default: Whether the value is also a default one
-	:returns:	'checked' attribute or an empty string
-	:rtype:	string
-
-	Permits you to display radio buttons in the state they were submitted.
-	This function is identical to the :php:func:`set_checkbox()` function above.
-
-	Example::
-
-		<input type="radio" name="myradio" value="1" <?php echo  set_radio('myradio', '1', TRUE); ?> />
-		<input type="radio" name="myradio" value="2" <?php echo  set_radio('myradio', '2'); ?> />
-
-	.. note:: If you are using the Form Validation class, you must always specify
-		a rule for your field, even if empty, in order for the ``set_*()``
-		functions to work. This is because if a Form Validation object is
-		defined, the control for ``set_*()`` is handed over to a method of the
-		class instead of the generic helper function.
-
-.. php:function:: form_error([$field = ''[, $prefix = ''[, $suffix = '']]])
-
-	:param	string	$field:	Field name
-	:param	string	$prefix: Error opening tag
-	:param	string	$suffix: Error closing tag
-	:returns:	HTML-formatted form validation error message(s)
-	:rtype:	string
-
-	Returns a validation error message from the :doc:`Form Validation Library
-	<../libraries/form_validation>`, associated with the specified field name.
-	You can optionally specify opening and closing tag(s) to put around the error
-	message.
-
-	Example::
-
-		// Assuming that the 'username' field value was incorrect:
-		echo form_error('myfield', '<div class="error">', '</div>');
-
-		// Would produce: <div class="error">Error message associated with the "username" field.</div>
-
-
-.. php:function:: validation_errors([$prefix = ''[, $suffix = '']])
-
-	:param	string	$prefix: Error opening tag
-	:param	string	$suffix: Error closing tag
-	:returns:	HTML-formatted form validation error message(s)
-	:rtype:	string
-
-	Similarly to the :php:func:`form_error()` function, returns all validation
-	error messages produced by the :doc:`Form Validation Library
-	<../libraries/form_validation>`, with optional opening and closing tags
-	around each of the messages.
-
-	Example::
-
-		echo validation_errors('<span class="error">', '</span>');
-
-		/*
-			Would produce, e.g.:
-
-			<span class="error">The "email" field doesn't contain a valid e-mail address!</span>
-			<span class="error">The "password" field doesn't match the "repeat_password" field!</span>
-
-		 */
-
-.. php:function:: form_prep($str)
-
-	:param	string	$str: Value to escape
-	:returns:	Escaped value
-	:rtype:	string
-
-	Allows you to safely use HTML and characters such as quotes within form
-	elements without breaking out of the form.
-
-	.. note:: If you use any of the form helper functions listed in this page the form
-		values will be prepped automatically, so there is no need to call this
-		function. Use it only if you are creating your own form elements.
-
-	.. note:: This function is DEPRECATED and is just an alias for
-		:doc:`common function <../general/common_functions>`
-		:func:`html_escape()` - please use that instead.

-
-The HTML Helper file contains functions that assist in working with
-HTML.
-
-.. contents::
-	:local:
-
-.. raw:: html
-
-	<div class="custom-index container"></div>
-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('html');
-
-Available Functions
-===================
-
-The following functions are available:
-
-
-.. php:function:: heading([$data = ''[, $h = '1'[, $attributes = '']]])
-
-	:param	string	$data: Content
-	:param	string	$h: Heading level
-	:param	mixed	$attributes: HTML attributes
-	:returns:	HTML heading tag
-	:rtype:	string
-
-	Lets you create HTML heading tags. The first parameter will contain the
-	data, the second the size of the heading. Example::
-
-		echo heading('Welcome!', 3);
-
-	The above would produce: <h3>Welcome!</h3>
-
-	Additionally, in order to add attributes to the heading tag such as HTML
-	classes, ids or inline styles, a third parameter accepts either a string
-	or an array::
-
-		echo heading('Welcome!', 3, 'class="pink"');
-		echo heading('How are you?', 4, array('id' => 'question', 'class' => 'green'));
-
-	The above code produces:
-
-	.. code-block:: html
-
-		<h3 class="pink">Welcome!<h3>
-		<h4 id="question" class="green">How are you?</h4>
-
-.. php:function:: img([$src = ''[, $index_page = FALSE[, $attributes = '']]])
-
-	:param	string	$src: Image source data
-	:param	bool	$index_page: Whether to treat $src as a routed URI string
-	:param	array	$attributes: HTML attributes
-	:returns:	HTML image tag
-	:rtype:	string
-
-	Lets you create HTML <img /> tags. The first parameter contains the
-	image source. Example::
-
-		echo img('images/picture.jpg'); // gives <img src="http://site.com/images/picture.jpg" />
-
-	There is an optional second parameter that is a TRUE/FALSE value that
-	specifics if the *src* should have the page specified by
-	``$config['index_page']`` added to the address it creates.
-	Presumably, this would be if you were using a media controller::

-		echo img('images/picture.jpg', TRUE); // gives <img src="http://site.com/index.php/images/picture.jpg" alt="" />
-
-	Additionally, an associative array can be passed to the ``img()`` function
-	for complete control over all attributes and values. If an *alt* attribute
-	is not provided, CodeIgniter will generate an empty string.
-
-	Example::
-
-		$image_properties = array(
-			'src' 	=> 'images/picture.jpg',
-			'alt' 	=> 'Me, demonstrating how to eat 4 slices of pizza at one time',
-			'class' => 'post_images',
-			'width' => '200',
-			'height'=> '200',
-			'title' => 'That was quite a night',
-			'rel' 	=> 'lightbox'
-		);
-
-		img($image_properties);
-		// <img src="http://site.com/index.php/images/picture.jpg" alt="Me, demonstrating how to eat 4 slices of pizza at one time" class="post_images" width="200" height="200" title="That was quite a night" rel="lightbox" />
-
-.. php:function:: link_tag([$href = ''[, $rel = 'stylesheet'[, $type = 'text/css'[, $title = ''[, $media = ''[, $index_page = FALSE]]]]]])
-
-	:param	string	$href: What are we linking to
-	:param	string	$rel: Relation type
-	:param	string	$type: Type of the related document
-	:param	string	$title: Link title
-	:param	string	$media: Media type
-	:param	bool	$index_page: Whether to treat $src as a routed URI string
-	:returns:	HTML link tag
-	:rtype:	string
-
-	Lets you create HTML <link /> tags. This is useful for stylesheet links,
-	as well as other links. The parameters are *href*, with optional *rel*,
-	*type*, *title*, *media* and *index_page*.
-
-	*index_page* is a boolean value that specifies if the *href* should have
-	the page specified by ``$config['index_page']`` added to the address it creates.
-
-	Example::
-
-		echo link_tag('css/mystyles.css');
-		// gives <link href="http://site.com/css/mystyles.css" rel="stylesheet" type="text/css" />
-
-	Further examples::
-
-		echo link_tag('favicon.ico', 'shortcut icon', 'image/ico');
-		// <link href="http://site.com/favicon.ico" rel="shortcut icon" type="image/ico" />
-
-		echo link_tag('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');
-		// <link href="http://site.com/feed" rel="alternate" type="application/rss+xml" title="My RSS Feed" />
-
-	Additionally, an associative array can be passed to the ``link()`` function
-	for complete control over all attributes and values::
-
-		$link = array(
-			'href'	=> 'css/printer.css',
-			'rel'	=> 'stylesheet',
-			'type'	=> 'text/css',
-			'media'	=> 'print'
-		);
-
-		echo link_tag($link);
-		// <link href="http://site.com/css/printer.css" rel="stylesheet" type="text/css" media="print" />
-
-
-.. php:function:: ul($list[, $attributes = ''])
-
-	:param	array	$list: List entries
-	:param	array	$attributes: HTML attributes
-	:returns:	HTML-formatted unordered list
-	:rtype:	string
-
-	Permits you to generate unordered HTML lists from simple or
-	multi-dimensional arrays. Example::
-
-		$list = array(
-			'red',
-			'blue',
-			'green',
-			'yellow'
-		);
-
-		$attributes = array(
-			'class'	=> 'boldlist',
-			'id'	=> 'mylist'
-		);
-
-		echo ul($list, $attributes);
-
-	The above code will produce this:
-
-	.. code-block:: html
-
-		<ul class="boldlist" id="mylist">
-			<li>red</li>
-			<li>blue</li>
-			<li>green</li>
-			<li>yellow</li>
-		</ul>
-
-	Here is a more complex example, using a multi-dimensional array::
-
-		$attributes = array(
-			'class'	=> 'boldlist',
-			'id'	=> 'mylist'
-		);
-
-		$list = array(
-			'colors'  => array(
-				'red',
-				'blue',
-				'green'
-			),
-			'shapes'  => array(
-				'round',
-				'square',
-				'circles' => array(
-					'ellipse',
-					'oval',
-					'sphere'
-				)
-			),
-			'moods'  => array(
-				'happy',
-				'upset' => array(
-					'defeated' => array(
-						'dejected',
-						'disheartened',
-						'depressed'
-					),
-					'annoyed',
-					'cross',
-					'angry'
-				)
-			)
-		);
-
-		echo ul($list, $attributes);
-
-	The above code will produce this:
-
-	.. code-block:: html
-
-		<ul class="boldlist" id="mylist">
-			<li>colors
-				<ul>
-					<li>red</li>
-					<li>blue</li>

-			</li>
-			<li>shapes
-				<ul>
-					<li>round</li>
-					<li>suare</li>
-					<li>circles
-						<ul>
-							<li>elipse</li>

-Smiley Helper
-#############
-
-The Smiley Helper file contains functions that let you manage smileys
-(emoticons).
-
-.. important:: The Smiley helper is DEPRECATED and should not be used.
-	It is currently only kept for backwards compatibility.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('smiley');
-
-Overview
-========
-
-The Smiley helper has a renderer that takes plain text smileys, like
-:-) and turns them into a image representation, like |smile!|
-
-It also lets you display a set of smiley images that when clicked will
-be inserted into a form field. For example, if you have a blog that
-allows user commenting you can show the smileys next to the comment
-form. Your users can click a desired smiley and with the help of some
-JavaScript it will be placed into the form field.
-
-Clickable Smileys Tutorial
-==========================
-
-Here is an example demonstrating how you might create a set of clickable
-smileys next to a form field. This example requires that you first
-download and install the smiley images, then create a controller and the
-View as described.
-
-.. important:: Before you begin, please `download the smiley images
-	<https://ellislab.com/asset/ci_download_files/smileys.zip>`_
-	and put them in a publicly accessible place on your server.
-	This helper also assumes you have the smiley replacement array
-	located at `application/config/smileys.php`
-
-The Controller
---------------
-
-In your **application/controllers/** directory, create a file called
-Smileys.php and place the code below in it.
-
-.. important:: Change the URL in the :php:func:`get_clickable_smileys()`
-	function below so that it points to your smiley folder.
-
-You'll notice that in addition to the smiley helper, we are also using
-the :doc:`Table Class <../libraries/table>`::
-
-	<?php
-
-	class Smileys extends CI_Controller {
-
-		public function index()
-		{
-			$this->load->helper('smiley');
-			$this->load->library('table');
-
-			$image_array = get_clickable_smileys('http://example.com/images/smileys/', 'comments');
-			$col_array = $this->table->make_columns($image_array, 8);
-
-			$data['smiley_table'] = $this->table->generate($col_array);
-			$this->load->view('smiley_view', $data);
-		}
-
-	}
-
-In your **application/views/** directory, create a file called **smiley_view.php**
-and place this code in it::
-
-	<html>
-		<head>
-			<title>Smileys</title>
-			<?php echo smiley_js(); ?>
-		</head>
-		<body>
-			<form name="blog">
-				<textarea name="comments" id="comments" cols="40" rows="4"></textarea>
-			</form>
-			<p>Click to insert a smiley!</p>
-			<?php echo $smiley_table; ?> </body> </html>
-			When you have created the above controller and view, load it by visiting http://www.example.com/index.php/smileys/
-		</body>
-	</html>
-
-Field Aliases
--------------
-
-When making changes to a view it can be inconvenient to have the field
-id in the controller. To work around this, you can give your smiley
-links a generic name that will be tied to a specific id in your view.
-
-::
-
-	$image_array = get_smiley_links("http://example.com/images/smileys/", "comment_textarea_alias");
-
-To map the alias to the field id, pass them both into the
-:func:`smiley_js()` function::
-
-	$image_array = smiley_js("comment_textarea_alias", "comments");
-
-Available Functions
-===================
-
-.. php:function:: get_clickable_smileys($image_url[, $alias = ''[, $smileys = NULL]])
-
-	:param	string	$image_url: URL path to the smileys directory
-	:param	string	$alias: Field alias
-	:returns:	An array of ready to use smileys
-	:rtype:	array
-
-	Returns an array containing your smiley images wrapped in a clickable
-	link. You must supply the URL to your smiley folder and a field id or
-	field alias.
-
-	Example::
-
-		$image_array = get_clickable_smileys('http://example.com/images/smileys/', 'comment');
-
-.. php:function:: smiley_js([$alias = ''[, $field_id = ''[, $inline = TRUE]]])
-
-	:param	string	$alias: Field alias
-	:param	string	$field_id: Field ID
-	:param	bool	$inline: Whether we're inserting an inline smiley
-	:returns:	Smiley-enabling JavaScript code
-	:rtype:	string
-
-	Generates the JavaScript that allows the images to be clicked and
-	inserted into a form field. If you supplied an alias instead of an id
-	when generating your smiley links, you need to pass the alias and
-	corresponding form id into the function. This function is designed to be
-	placed into the <head> area of your web page.
-
-	Example::
-
-		<?php echo smiley_js(); ?>
-
-.. php:function:: parse_smileys([$str = ''[, $image_url = ''[, $smileys = NULL]]])
-
-	:param	string	$str: Text containing smiley codes
-	:param	string	$image_url: URL path to the smileys directory
-	:param	array	$smileys: An array of smileys
-	:returns:	Parsed smileys
-	:rtype:	string
-
-	Takes a string of text as input and replaces any contained plain text
-	smileys into the image equivalent. The first parameter must contain your
-	string, the second must contain the URL to your smiley folder
-
-	Example::
-
-		$str = 'Here are some smileys: :-)  ;-)';
-		$str = parse_smileys($str, 'http://example.com/images/smileys/');
-		echo $str;
-
-.. |smile!| image:: ../images/smile.gif

-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('string');
-
-Available Functions
-===================
-
-The following functions are available:
-
-
-.. php:function:: random_string([$type = 'alnum'[, $len = 8]])
-
-	:param	string	$type: Randomization type
-	:param	int	$len: Output string length
-	:returns:	A random string
-	:rtype:	string
-
-	Generates a random string based on the type and length you specify.
-	Useful for creating passwords or generating random hashes.
-
-	The first parameter specifies the type of string, the second parameter
-	specifies the length. The following choices are available:
-
-	-  **alpha**: A string with lower and uppercase letters only.
-	-  **alnum**: Alpha-numeric string with lower and uppercase characters.
-	-  **basic**: A random number based on ``mt_rand()``.
-	-  **numeric**: Numeric string.

-	-  **md5**: An encrypted random number based on ``md5()`` (fixed length of 32).
-	-  **sha1**: An encrypted random number based on ``sha1()`` (fixed length of 40).
-
-	Usage example::
-
-		echo random_string('alnum', 16);
-
-	.. note:: Usage of the *unique* and *encrypt* types is DEPRECATED. They
-		are just aliases for *md5* and *sha1* respectively.
-
-.. php:function:: increment_string($str[, $separator = '_'[, $first = 1]])
-
-	:param	string	$str: Input string
-	:param	string	$separator: Separator to append a duplicate number with
-	:param	int	$first: Starting number
-	:returns:	An incremented string
-	:rtype:	string
-
-	Increments a string by appending a number to it or increasing the
-	number. Useful for creating "copies" or a file or duplicating database
-	content which has unique titles or slugs.
-
-	Usage example::
-
-		echo increment_string('file', '_'); // "file_1"
-		echo increment_string('file', '-', 2); // "file-2"
-		echo increment_string('file_4'); // "file_5"
-
-
-.. php:function:: alternator($args)
-
-	:param	mixed	$args: A variable number of arguments
-	:returns:	Alternated string(s)
-	:rtype:	mixed
-
-	Allows two or more items to be alternated between, when cycling through
-	a loop. Example::
-
-		for ($i = 0; $i < 10; $i++)
-		{     
-			echo alternator('string one', 'string two');
-		}
-
-	You can add as many parameters as you want, and with each iteration of
-	your loop the next item will be returned.
-
-	::
-
-		for ($i = 0; $i < 10; $i++)
-		{     
-			echo alternator('one', 'two', 'three', 'four', 'five');
-		}
-
-	.. note:: To use multiple separate calls to this function simply call the
-		function with no arguments to re-initialize.
-
-.. php:function:: repeater($data[, $num = 1])
-
-	:param	string	$data: Input
-	:param	int	$num: Number of times to repeat
-	:returns:	Repeated string
-	:rtype:	string
-
-	Generates repeating copies of the data you submit. Example::
-
-		$string = "\n";
-		echo repeater($string, 30);
-
-	The above would generate 30 newlines.
-
-	.. note:: This function is DEPRECATED. Use the native ``str_repeat()``
-		instead.
-
-
-.. php:function:: reduce_double_slashes($str)
-
-	:param	string	$str: Input string
-	:returns:	A string with normalized slashes
-	:rtype:	string
-
-	Converts double slashes in a string to a single slash, except those

-
-	:param	mixed	$data: Input string or an array of strings
-	:returns:	String(s) with stripped slashes
-	:rtype:	mixed
-
-	Removes any slashes from an array of strings.
-
-	Example::
-
-		$str = array(
-			'question'  => 'Is your name O\'reilly?',
-			'answer' => 'No, my name is O\'connor.'
-		);
-
-		$str = strip_slashes($str);
-
-	The above will return the following array::
-
-		array(
-			'question'  => "Is your name O'reilly?",
-			'answer' => "No, my name is O'connor."
-		);
-
-	.. note:: For historical reasons, this function will also accept
-		and handle string inputs. This however makes it just an
-		alias for ``stripslashes()``.
-
-.. php:function:: trim_slashes($str)
-
-	:param	string	$str: Input string
-	:returns:	Slash-trimmed string
-	:rtype:	string
-

-
-		$string = "Fred, Bill,, Joe, Jimmy";
-		$string = reduce_multiples($string,","); //results in "Fred, Bill, Joe, Jimmy"
-
-	If the third parameter is set to TRUE it will remove occurrences of the
-	character at the beginning and the end of the string. Example::
-
-		$string = ",Fred, Bill,, Joe, Jimmy,";
-		$string = reduce_multiples($string, ", ", TRUE); //results in "Fred, Bill, Joe, Jimmy"
-
-.. php:function:: quotes_to_entities($str)

-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('text');
-
-Available Functions
-===================
-
-The following functions are available:
-
-.. php:function:: word_limiter($str[, $limit = 100[, $end_char = '&#8230;']])
-
-	:param	string	$str: Input string
-	:param	int	$limit: Limit
-	:param	string	$end_char: End character (usually an ellipsis)
-	:returns:	Word-limited string
-	:rtype:	string
-
-	Truncates a string to the number of *words* specified. Example::
-
-		$string = "Here is a nice text string consisting of eleven words.";
-		$string = word_limiter($string, 4);
-		// Returns:  Here is a nice
-
-	The third parameter is an optional suffix added to the string. By
-	default it adds an ellipsis.
-
-
-.. php:function:: character_limiter($str[, $n = 500[, $end_char = '&#8230;']])
-
-	:param	string	$str: Input string
-	:param	int	$n: Number of characters
-	:param	string	$end_char: End character (usually an ellipsis)
-	:returns:	Character-limited string
-	:rtype:	string
-
-	Truncates a string to the number of *characters* specified. It
-	maintains the integrity of words so the character count may be slightly
-	more or less than what you specify.
-
-	Example::
-
-		$string = "Here is a nice text string consisting of eleven words.";
-		$string = character_limiter($string, 20);
-		// Returns:  Here is a nice text string
-
-	The third parameter is an optional suffix added to the string, if
-	undeclared this helper uses an ellipsis.
-
-	.. note:: If you need to truncate to an exact number of characters please
-		see the :php:func:`ellipsize()` function below.
-
-.. php:function:: ascii_to_entities($str)
-
-	:param	string	$str: Input string
-	:returns:	A string with ASCII values converted to entities
-	:rtype:	string
-
-	Converts ASCII values to character entities, including high ASCII and MS
-	Word characters that can cause problems when used in a web page, so that
-	they can be shown consistently regardless of browser settings or stored
-	reliably in a database. There is some dependence on your server's
-	supported character sets, so it may not be 100% reliable in all cases,
-	but for the most part it should correctly identify characters outside
-	the normal range (like accented characters).
-
-	Example::
-
-		$string = ascii_to_entities($string);
-
-.. php:function::entities_to_ascii($str[, $all = TRUE])
-
-	:param	string	$str: Input string
-	:param	bool	$all: Whether to convert unsafe entities as well
-	:returns:	A string with HTML entities converted to ASCII characters
-	:rtype:	string
-
-	This function does the opposite of :php:func:`ascii_to_entities()`.
-	It turns character entities back into ASCII.
-
-.. php:function:: convert_accented_characters($str)
-
-	:param	string	$str: Input string
-	:returns:	A string with accented characters converted
-	:rtype:	string
-
-	Transliterates high ASCII characters to low ASCII equivalents. Useful
-	when non-English characters need to be used where only standard ASCII
-	characters are safely used, for instance, in URLs.
-
-	Example::
-
-		$string = convert_accented_characters($string);
-
-	.. note:: This function uses a companion config file
-		`application/config/foreign_chars.php` to define the to and
-		from array for transliteration.
-
-.. php:function:: word_censor($str, $censored[, $replacement = ''])
-
-	:param	string	$str: Input string
-	:param	array	$censored: List of bad words to censor
-	:param	string	$replacement: What to replace bad words with
-	:returns:	Censored string
-	:rtype:	string
-
-	Enables you to censor words within a text string. The first parameter
-	will contain the original string. The second will contain an array of
-	words which you disallow. The third (optional) parameter can contain
-	a replacement value for the words. If not specified they are replaced
-	with pound signs: ####.
-
-	Example::
-
-		$disallowed = array('darn', 'shucks', 'golly', 'phooey');
-		$string = word_censor($string, $disallowed, 'Beep!');
-
-.. php:function:: highlight_code($str)
-
-	:param	string	$str: Input string
-	:returns:	String with code highlighted via HTML
-	:rtype:	string
-
-	Colorizes a string of code (PHP, HTML, etc.). Example::
-
-		$string = highlight_code($string);
-
-	The function uses PHP's ``highlight_string()`` function, so the
-	colors used are the ones specified in your php.ini file.
-
-
-.. php:function:: highlight_phrase($str, $phrase[, $tag_open = '<mark>'[, $tag_close = '</mark>']])
-
-	:param	string	$str: Input string
-	:param	string	$phrase: Phrase to highlight
-	:param	string	$tag_open: Opening tag used for the highlight
-	:param	string	$tag_close: Closing tag for the highlight
-	:returns:	String with a phrase highlighted via HTML
-	:rtype:	string
-
-	Will highlight a phrase within a text string. The first parameter will
-	contain the original string, the second will contain the phrase you wish
-	to highlight. The third and fourth parameters will contain the
-	opening/closing HTML tags you would like the phrase wrapped in.
-
-	Example::
-
-		$string = "Here is a nice text string about nothing in particular.";
-		echo highlight_phrase($string, "nice text", '<span style="color:#990000;">', '</span>');
-
-	The above code prints::
-
-		Here is a <span style="color:#990000;">nice text</span> string about nothing in particular.
-
-	.. note:: This function used to use the ``<strong>`` tag by default. Older browsers
-		might not support the new HTML5 mark tag, so it is recommended that you
-		insert the following CSS code into your stylesheet if you need to support
-		such browsers::
-
-			mark {
-				background: #ff0;
-				color: #000;
-			};
-
-.. php:function:: word_wrap($str[, $charlim = 76])
-
-	:param	string	$str: Input string
-	:param	int	$charlim: Character limit
-	:returns:	Word-wrapped string
-	:rtype:	string
-
-	Wraps text at the specified *character* count while maintaining
-	complete words.
-
-	Example::
-
-		$string = "Here is a simple string of text that will help us demonstrate this function.";
-		echo word_wrap($string, 25);
-
-		// Would produce:  
-		// Here is a simple string
-		// of text that will help us
-		// demonstrate this
-		// function.
-
-.. php:function:: ellipsize($str, $max_length[, $position = 1[, $ellipsis = '&hellip;']])
-
-	:param	string	$str: Input string
-	:param	int	$max_length: String length limit
-	:param	mixed	$position: Position to split at (int or float)
-	:param	string	$ellipsis: What to use as the ellipsis character
-	:returns:	Ellipsized string
-	:rtype:	string
-
-	This function will strip tags from a string, split it at a defined
-	maximum length, and insert an ellipsis.
-
-	The first parameter is the string to ellipsize, the second is the number
-	of characters in the final string. The third parameter is where in the
-	string the ellipsis should appear from 0 - 1, left to right. For
-	example. a value of 1 will place the ellipsis at the right of the
-	string, .5 in the middle, and 0 at the left.
-
-	An optional forth parameter is the kind of ellipsis. By default,
-	&hellip; will be inserted.
-
-	Example::
-
-		$str = 'this_string_is_entirely_too_long_and_might_break_my_design.jpg';
-		echo ellipsize($str, 32, .5);
-
-	Produces::
-
-		this_string_is_e&hellip;ak_my_design.jpg

-URL Helper
-##########
-
-The URL Helper file contains functions that assist in working with URLs.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-Loading this Helper
-===================
-
-This helper is loaded using the following code::
-
-	$this->load->helper('url');
-
-Available Functions
-===================
-
-The following functions are available:
-
-.. php:function:: site_url([$uri = ''[, $protocol = NULL]])
-
-	:param	string	$uri: URI string
-	:param	string	$protocol: Protocol, e.g. 'http' or 'https'
-	:returns:	Site URL
-	:rtype:	string
-
-	Returns your site URL, as specified in your config file. The index.php
-	file (or whatever you have set as your site **index_page** in your config
-	file) will be added to the URL, as will any URI segments you pass to the
-	function, plus the **url_suffix** as set in your config file.
-
-	You are encouraged to use this function any time you need to generate a
-	local URL so that your pages become more portable in the event your URL
-	changes.
-
-	Segments can be optionally passed to the function as a string or an
-	array. Here is a string example::
-
-		echo site_url('news/local/123');
-
-	The above example would return something like:
-	*http://example.com/index.php/news/local/123*
-
-	Here is an example of segments passed as an array::
-
-		$segments = array('news', 'local', '123');
-		echo site_url($segments);
-
-	This function is an alias for ``CI_Config::site_url()``. For more info,
-	please see the :doc:`Config Library <../libraries/config>` documentation.
-
-.. php:function:: base_url($uri = '', $protocol = NULL)
-
-	:param	string	$uri: URI string
-	:param	string	$protocol: Protocol, e.g. 'http' or 'https'
-	:returns:	Base URL
-	:rtype:	string
-
-	Returns your site base URL, as specified in your config file. Example::
-
-		echo base_url();
-
-	This function returns the same thing as :php:func:`site_url()`, without
-	the *index_page* or *url_suffix* being appended.
-
-	Also like :php:func:`site_url()`, you can supply segments as a string or
-	an array. Here is a string example::
-
-		echo base_url("blog/post/123");
-
-	The above example would return something like:
-	*http://example.com/blog/post/123*
-
-	This is useful because unlike :php:func:`site_url()`, you can supply a
-	string to a file, such as an image or stylesheet. For example::
-
-		echo base_url("images/icons/edit.png");
-
-	This would give you something like:
-	*http://example.com/images/icons/edit.png*
-
-	This function is an alias for ``CI_Config::base_url()``. For more info,
-	please see the :doc:`Config Library <../libraries/config>` documentation.
-
-.. php:function:: current_url()
-
-	:returns:	The current URL
-	:rtype:	string
-
-	Returns the full URL (including segments) of the page being currently
-	viewed.
-
-	.. note:: Calling this function is the same as doing this:
-		|
-		| site_url(uri_string());
-
-
-.. php:function:: uri_string()
-
-	:returns:	An URI string
-	:rtype:	string
-
-	Returns the URI segments of any page that contains this function.
-	For example, if your URL was this::
-
-		http://some-site.com/blog/comments/123
-
-	The function would return::
-
-		blog/comments/123
-
-	This function is an alias for ``CI_Config::uri_string()``. For more info,
-	please see the :doc:`Config Library <../libraries/config>` documentation.
-
-
-.. php:function:: index_page()
-
-	:returns:	'index_page' value
-	:rtype:	mixed
-
-	Returns your site **index_page**, as specified in your config file.
-	Example::
-
-		echo index_page();
-
-.. php:function:: anchor($uri = '', $title = '', $attributes = '')
-
-	:param	string	$uri: URI string
-	:param	string	$title: Anchor title
-	:param	mixed	$attributes: HTML attributes
-	:returns:	HTML hyperlink (anchor tag)
-	:rtype:	string
-
-	Creates a standard HTML anchor link based on your local site URL.
-
-	The first parameter can contain any segments you wish appended to the
-	URL. As with the :php:func:`site_url()` function above, segments can
-	be a string or an array.
-
-	.. note:: If you are building links that are internal to your application
-		do not include the base URL (http&#58;//...). This will be added
-		automatically from the information specified in your config file.
-		Include only the URI segments you wish appended to the URL.
-
-	The second segment is the text you would like the link to say. If you
-	leave it blank, the URL will be used.
-
-	The third parameter can contain a list of attributes you would like
-	added to the link. The attributes can be a simple string or an
-	associative array.
-
-	Here are some examples::
-
-		echo anchor('news/local/123', 'My News', 'title="News title"');
-		// Prints: <a href="http://example.com/index.php/news/local/123" title="News title">My News</a>
-
-		echo anchor('news/local/123', 'My News', array('title' => 'The best news!'));
-		// Prints: <a href="http://example.com/index.php/news/local/123" title="The best news!">My News</a>
-
-		echo anchor('', 'Click here');
-		// Prints: <a href="http://example.com">Click Here</a>
-
-
-.. php:function:: anchor_popup($uri = '', $title = '', $attributes = FALSE)
-
-	:param	string	$uri: URI string
-	:param	string	$title: Anchor title
-	:param	mixed	$attributes: HTML attributes
-	:returns:	Pop-up hyperlink
-	:rtype:	string
-
-	Nearly identical to the :php:func:`anchor()` function except that it
-	opens the URL in a new window. You can specify JavaScript window
-	attributes in the third parameter to control how the window is opened.
-	If the third parameter is not set it will simply open a new window with
-	your own browser settings.
-
-	Here is an example with attributes::
-
-		$atts = array(
-			'width'       => 800,
-			'height'      => 600,
-			'scrollbars'  => 'yes',
-			'status'      => 'yes',
-			'resizable'   => 'yes',
-			'screenx'     => 0,
-			'screeny'     => 0,
-			'window_name' => '_blank'
-		);
-
-		echo anchor_popup('news/local/123', 'Click Me!', $atts);
-
-	.. note:: The above attributes are the function defaults so you only need to
-		set the ones that are different from what you need. If you want the
-		function to use all of its defaults simply pass an empty array in the
-		third parameter:
-		|
-		| echo anchor_popup('news/local/123', 'Click Me!', array());
-
-	.. note:: The **window_name** is not really an attribute, but an argument to
-		the JavaScript `window.open() <http://www.w3schools.com/jsref/met_win_open.asp>`
-		method, which accepts either a window name or a window target.
-
-	.. note:: Any other attribute than the listed above will be parsed as an
-		HTML attribute to the anchor tag.
-
-
-.. php:function:: mailto($email, $title = '', $attributes = '')
-
-	:param	string	$email: E-mail address
-	:param	string	$title: Anchor title
-	:param	mixed	$attributes: HTML attributes
-	:returns:	A "mail to" hyperlink
-	:rtype:	string
-
-	Creates a standard HTML e-mail link. Usage example::
-
-		echo mailto('me@my-site.com', 'Click Here to Contact Me');
-
-	As with the :php:func:`anchor()` tab above, you can set attributes using the
-	third parameter::
-
-		$attributes = array('title' => 'Mail me');
-		echo mailto('me@my-site.com', 'Contact Me', $attributes);
-
-.. php:function:: safe_mailto($email, $title = '', $attributes = '')
-
-	:param	string	$email: E-mail address
-	:param	string	$title: Anchor title
-	:param	mixed	$attributes: HTML attributes
-	:returns:	A spam-safe "mail to" hyperlink
-	:rtype:	string
-
-	Identical to the :php:func:`mailto()` function except it writes an obfuscated
-	version of the *mailto* tag using ordinal numbers written with JavaScript to
-	help prevent the e-mail address from being harvested by spam bots.
-
-.. php:function:: auto_link($str, $type = 'both', $popup = FALSE)
-
-	:param	string	$str: Input string
-	:param	string	$type: Link type ('email', 'url' or 'both')
-	:param	bool	$popup: Whether to create popup links
-	:returns:	Linkified string
-	:rtype:	string
-
-	Automatically turns URLs and e-mail addresses contained in a string into
-	links. Example::
-
-		$string = auto_link($string);
-
-	The second parameter determines whether URLs and e-mails are converted or
-	just one or the other. Default behavior is both if the parameter is not
-	specified. E-mail links are encoded as :php:func:`safe_mailto()` as shown
-	above.
-
-	Converts only URLs::
-
-		$string = auto_link($string, 'url');
-
-	Converts only e-mail addresses::
-
-		$string = auto_link($string, 'email');
-
-	The third parameter determines whether links are shown in a new window.
-	The value can be TRUE or FALSE (boolean)::
-
-		$string = auto_link($string, 'both', TRUE);
-
-
-.. php:function:: url_title($str, $separator = '-', $lowercase = FALSE)
-
-	:param	string	$str: Input string
-	:param	string	$separator: Word separator
-	:param	bool	$lowercase: Whether to transform the output string to lower-case
-	:returns:	URL-formatted string
-	:rtype:	string
-
-	Takes a string as input and creates a human-friendly URL string. This is
-	useful if, for example, you have a blog in which you'd like to use the
-	title of your entries in the URL. Example::
-
-		$title = "What's wrong with CSS?";
-		$url_title = url_title($title);
-		// Produces: Whats-wrong-with-CSS
-
-	The second parameter determines the word delimiter. By default dashes
-	are used. Preferred options are: **-** (dash) or **_** (underscore)
-
-	Example::
-
-		$title = "What's wrong with CSS?";
-		$url_title = url_title($title, 'underscore');
-		// Produces: Whats_wrong_with_CSS
-
-	.. note:: Old usage of 'dash' and 'underscore' as the second parameter
-		is DEPRECATED.
-
-	The third parameter determines whether or not lowercase characters are
-	forced. By default they are not. Options are boolean TRUE/FALSE.
-
-	Example::
-
-		$title = "What's wrong with CSS?";
-		$url_title = url_title($title, 'underscore', TRUE);
-		// Produces: whats_wrong_with_css
-
-
-.. php:function:: prep_url($str = '')
-
-	:param	string	$str: URL string
-	:returns:	Protocol-prefixed URL string
-	:rtype:	string
-
-	This function will add http&#58;// in the event that a protocol prefix
-	is missing from a URL.
-
-	Pass the URL string to the function like this::
-
-		$url = prep_url('example.com');
-
-
-.. php:function:: redirect($uri = '', $method = 'auto', $code = NULL)
-
-	:param	string	$uri: URI string
-	:param	string	$method: Redirect method ('auto', 'location' or 'refresh')
-	:param	string	$code: HTTP Response code (usually 302 or 303)
-	:rtype:	void
-
-	Does a "header redirect" to the URI specified. If you specify the full
-	site URL that link will be built, but for local links simply providing
-	the URI segments to the controller you want to direct to will create the
-	link. The function will build the URL based on your config file values.
-
-	The optional second parameter allows you to force a particular redirection
-	method. The available methods are **auto**, **location** and **refresh**,
-	with location being faster but less reliable on IIS servers.
-	The default is **auto**, which will attempt to intelligently choose the
-	method based on the server environment.
-
-	The optional third parameter allows you to send a specific HTTP Response
-	Code - this could be used for example to create 301 redirects for search
-	engine purposes. The default Response Code is 302. The third parameter is
-	*only* available with **location** redirects, and not *refresh*. Examples::
-
-		if ($logged_in == FALSE)
-		{      
-			redirect('/login/form/');
-		}
-
-		// with 301 redirect
-		redirect('/article/13', 'location', 301);
-
-	.. note:: In order for this function to work it must be used before anything
-		is outputted to the browser since it utilizes server headers.
-
-	.. note:: For very fine grained control over headers, you should use the
-		:doc:`Output Library </libraries/output>` ``set_header()`` method.
-
-	.. note:: To IIS users: if you hide the `Server` HTTP header, the *auto*
-		method won't detect IIS, in that case it is advised you explicitly
-		use the **refresh** method.
-
-	.. note:: When the **location** method is used, an HTTP status code of 303
-		will *automatically* be selected when the page is currently accessed
-		via POST and HTTP/1.1 is used.
-
-	.. important:: This function will terminate script execution.

-#########################
-Installation Instructions
-#########################
-
-CodeIgniter is installed in four steps:
-
-#. Unzip the package.
-#. Upload the CodeIgniter folders and files to your server. Normally the
-   *index.php* file will be at your root.
-#. Open the *application/config/config.php* file with a text editor and
-   set your base URL. If you intend to use encryption or sessions, set
-   your encryption key.
-#. If you intend to use a database, open the
-   *application/config/database.php* file with a text editor and set your
-   database settings.
-
-If you wish to increase security by hiding the location of your
-CodeIgniter files you can rename the system and application folders to
-something more private. If you do rename them, you must open your main
-*index.php* file and set the ``$system_path`` and ``$application_folder``
-variables at the top of the file with the new name you've chosen.
-
-For the best security, both the system and any application folders
-should be placed above web root so that they are not directly accessible
-via a browser. By default, *.htaccess* files are included in each folder
-to help prevent direct access, but it is best to remove them from public
-access entirely in case the web server configuration changes or doesn't
-abide by the *.htaccess*.
-
-If you would like to keep your views public it is also possible to move
-the views folder out of your application folder.
-
-After moving them, open your main index.php file and set the
-``$system_path``, ``$application_folder`` and ``$view_folder`` variables,
-preferably with a full path, e.g. '*/www/MyUser/system*'.
-
-One additional measure to take in production environments is to disable
-PHP error reporting and any other development-only functionality. In
-CodeIgniter, this can be done by setting the ``ENVIRONMENT`` constant, which
-is more fully described on the :doc:`security
-page <../general/security>`.
-
-That's it!
-
-If you're new to CodeIgniter, please read the :doc:`Getting
-Started <../overview/getting_started>` section of the User Guide
-to begin learning how to build dynamic PHP applications. Enjoy!

-Troubleshooting
-###############
-
-If you find that no matter what you put in your URL only your default
-page is loading, it might be that your server does not support the
-REQUEST_URI variable needed to serve search-engine friendly URLs. As a
-first step, open your *application/config/config.php* file and look for
-the URI Protocol information. It will recommend that you try a couple
-alternate settings. If it still doesn't work after you've tried this
-you'll need to force CodeIgniter to add a question mark to your URLs. To
-do this open your *application/config/config.php* file and change this::
-
-	$config['index_page'] = "index.php";
-
-To this::
-
-	$config['index_page'] = "index.php?";

-#########################
-Upgrading from 1.2 to 1.3
-#########################
-
-.. note:: The instructions on this page assume you are running version
-	1.2. If you have not upgraded to that version please do so first.
-
-Before performing an update you should take your site offline by
-replacing the index.php file with a static one.
-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace the following directories in your "system" folder with the new
-versions:
-
-.. note:: If you have any custom developed files in these folders please
-	make copies of them first.
-
--  application/**models**/ (new for 1.3)
--  codeigniter (new for 1.3)
--  drivers
--  helpers
--  init
--  language
--  libraries
--  plugins
--  scaffolding
-
-Step 2: Update your error files
-===============================
-
-Version 1.3 contains two new error templates located in
-application/errors, and for naming consistency the other error templates
-have been renamed.
-
-If you **have not** customized any of the error templates simply replace
-this folder:
-
--  application/errors/
-
-If you **have** customized your error templates, rename them as follows:
-
--  404.php = error_404.php
--  error.php = error_general.php
--  error_db.php (new)
--  error_php.php (new)
-
-Step 3: Update your index.php file
-==================================
-
-Please open your main index.php file (located at your root). At the very
-bottom of the file, change this::
-
-	require_once BASEPATH.'libraries/Front_controller'.EXT;
-
-To this::
-
-	require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;
-
-Step 4: Update your config.php file
-===================================
-
-Open your application/config/config.php file and add these new items::
-
-
-    /*
-    |------------------------------------------------
-    | URL suffix
-    |------------------------------------------------
-    |
-    | This option allows you to add a suffix to all URLs.
-    | For example, if a URL is this:
-    |
-    | example.com/index.php/products/view/shoes
-    |
-    | You can optionally add a suffix, like ".html",
-    | making the page appear to be of a certain type:
-    |
-    | example.com/index.php/products/view/shoes.html
-    |
-    */
-    $config['url_suffix'] = "";
-
-
-    /*
-    |------------------------------------------------
-    | Enable Query Strings
-    |------------------------------------------------
-    |
-    | By default CodeIgniter uses search-engine and
-    | human-friendly segment based URLs:
-    |
-    | example.com/who/what/where/
-    |
-    | You can optionally enable standard query string
-    | based URLs:
-    |
-    | example.com?who=me&what=something&where=here
-    |
-    | Options are: TRUE or FALSE (boolean)
-    |
-    | The two other items let you set the query string "words"
-    | that will invoke your controllers and functions:
-    | example.com/index.php?c=controller&m=function
-    |
-    */
-    $config['enable_query_strings'] = FALSE;
-    $config['controller_trigger'] = 'c';
-    $config['function_trigger'] = 'm';
-
-Step 5: Update your database.php file
-=====================================
-
-Open your application/config/database.php file and add these new items::
-
-
-    $db['default']['dbprefix'] = "";
-    $db['default']['active_r'] = TRUE;
-
-Step 6: Update your user guide
-==============================
-
-Please also replace your local copy of the user guide with the new
-version.

-Upgrading from 1.6.3 to 1.7.0
-#############################
-
-Before performing an update you should take your site offline by

-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace these files and directories in your "system" folder with the new

-

--  system/database
--  system/helpers
--  system/language

-
-.. note:: If you have any custom developed files in these folders please
-	make copies of them first.
-
-Step 2: Update your Session Table
-=================================
-
-If you are using the Session class in your application, AND if you are
-storing session data to a database, you must add a new column named
-user_data to your session table. Here is an example of what this column
-might look like for MySQL::
-
-	user_data text NOT NULL
-
-To add this column you will run a query similar to this::
-
-	ALTER TABLE `ci_sessions` ADD `user_data` text NOT NULL
-
-You'll find more information regarding the new Session functionality in
-the :doc:`Session class <../libraries/sessions>` page.
-
-Step 3: Update your Validation Syntax
-=====================================
-
-This is an **optional**, but recommended step, for people currently
-using the Validation class. CI 1.7 introduces a new :doc:`Form Validation
-class <../libraries/form_validation>`, which deprecates the old
-Validation library. We have left the old one in place so that existing
-applications that use it will not break, but you are encouraged to
-migrate to the new version as soon as possible. Please read the user
-guide carefully as the new library works a little differently, and has
-several new features.
-
-Step 4: Update your user guide
-==============================
-
-Please replace your local copy of the user guide with the new version,
-including the image files.

-
-*******************
-Update Instructions
-*******************
-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace all files and directories in your "system" folder **except**
-your application folder.
-
-.. note:: If you have any custom developed files in these folders please
-	make copies of them first.
-
-Step 2: Adjust get_dir_file_info() where necessary
-=====================================================
-
-Version 2.0.0 brings a non-backwards compatible change to
-get_dir_file_info() in the :doc:`File
-Helper <../helpers/file_helper>`. Non-backwards compatible changes
-are extremely rare in CodeIgniter, but this one we feel was warranted
-due to how easy it was to create serious server performance issues. If
-you *need* recursiveness where you are using this helper function,
-change such instances, setting the second parameter, $top_level_only
-to FALSE::
-
-	get_dir_file_info('/path/to/directory', FALSE);
-
-Step 3: Convert your Plugins to Helpers
-=======================================
-
-2.0.0 gets rid of the "Plugin" system as their functionality was
-identical to Helpers, but non-extensible. You will need to rename your
-plugin files from filename_pi.php to filename_helper.php, move them to
-your helpers folder, and change all instances of::
-
-	$this->load->plugin('foo');
-
-to ::
-
-	$this->load->helper('foo');
-
-
-Step 4: Update stored encrypted data
-====================================
-
-.. note:: If your application does not use the Encrypt library, does
-	not store Encrypted data permanently, or is on an environment that does
-	not support Mcrypt, you may skip this step.
-
-The Encrypt library has had a number of improvements, some for
-encryption strength and some for performance, that has an unavoidable
-consequence of making it no longer possible to decode encrypted data
-produced by the original version of this library. To help with the
-transition, a new method has been added, encode_from_legacy() that
-will decode the data with the original algorithm and return a re-encoded
-string using the improved methods. This will enable you to easily
-replace stale encrypted data with fresh in your applications, either on
-the fly or en masse.
-
-Please read :doc:`how to use this
-method <../libraries/encrypt>` in the Encrypt library
-documentation.
-
-Step 5: Remove loading calls for the compatibility helper.
-==========================================================
-
-The compatibility helper has been removed from the CodeIgniter core. All
-methods in it should be natively available in supported PHP versions.
-
-Step 6: Update Class extension
-==============================
-
-All core classes are now prefixed with CI\_. Update Models and
-Controllers to extend CI_Model and CI_Controller, respectively.
-
-Step 7: Update Parent Constructor calls
-=======================================
-
-All native CodeIgniter classes now use the PHP 5 \__construct()
-convention. Please update extended libraries to call
-parent::\__construct().
-
-Step 8: Move any core extensions to application/core
-====================================================
-
-Any extensions to core classes (e.g. MY_Controller.php) in your
-application/libraries folder must be moved to the new 
-application/core folder.
-
-Step 9: Update your user guide
-==============================
-
-Please replace your local copy of the user guide with the new version,
-including the image files.
-
-
-************
-Update Notes
-************
-
-Please refer to the :ref:`2.0.0 Change Log <2.0.0-changelog>` for full
-details, but here are some of the larger changes that are more likely to
-impact your code:
-
-- Scaffolding has been removed.
-- The CAPTCHA plugin in now a :doc:`helper </helpers/captcha_helper>`.
-- The JavaScript calendar plugin was removed.
-- The *system/cache* and *system/logs* directories are now in the application
-  directory.
-- The Validation class has been removed.  Please see the
-  :doc:`Form Validation library </libraries/form_validation>`
-- "default" is now a reserved name.
-- The xss_clean() function has moved to the :doc:`Security Class
-  </libraries/security>`.
-- do_xss_clean() now returns FALSE if the uploaded file fails XSS checks.
-- The :doc:`Session Class </libraries/sessions>` requires now the use of an
-  encryption key set in the config file.
-- The following deprecated Active Record functions have been removed:
-  ``orwhere``, ``orlike``, ``groupby``, ``orhaving``, ``orderby``,
-  ``getwhere``.
-- ``_drop_database()`` and ``_create_database()`` functions have been removed
-  from the db utility drivers.
-- The ``dohash()`` function of the :doc:`Security helper
-  </helpers/security_helper>`
-  has been renamed to ``do_hash()`` for naming consistency.
-
-The config folder
-=================
-
-The following files have been changed:
-
-- config.php
-- database.php
-- mimes.php
-- routes.php
-- user_agents.php
-
-The following files have been added:
-
-- foreign_chars.php

-
-Step 3: Check for forms posting to default controller
-=====================================================
-
-The default behavior for form_open() when called with no parameters
-used to be to post to the default controller, but it will now just leave
-an empty action="" meaning the form will submit to the current URL. If
-submitting to the default controller was the expected behavior it will
-need to be changed from::
-
-	echo form_open(); //<form action="" method="post" accept-charset="utf-8">
-
-to use either a / or base_url()::
-
-	echo form_open('/'); //<form action="http://example.com/index.php/" method="post" accept-charset="utf-8">
-	echo form_open(base_url()); //<form action="http://example.com/" method="post" accept-charset="utf-8">

-they will need to be made fresh in this new one.
-
-.. note:: If you have any custom developed files in these folders please

-
-Step 2: Update your main index.php file
-=======================================
-
-If you are running a stock index.php file simply replace your version
-with the new one.
-
-If your index.php file has internal modifications, please add your
-modifications to the new file and use it.
-
-Step 3: Replace config/user_agents.php
-=======================================
-
-This config file has been updated to contain more user agent types,
-please copy it to application/config/user_agents.php.
-
-Step 4: Change references of the EXT constant to ".php"
-=======================================================
-
-.. note:: The EXT Constant has been marked as deprecated, but has not
-	been removed from the application. You are encouraged to make the
-	changes sooner rather than later.
-
-Step 5: Remove APPPATH.'third_party' from autoload.php
-=======================================================
-
-Open application/config/autoload.php, and look for the following::
-
-	$autoload['packages'] = array(APPPATH.'third_party');
-
-If you have not chosen to load any additional packages, that line can be
-changed to::
-
-	$autoload['packages'] = array();
-
-Which should provide for nominal performance gains if not autoloading
-packages.
-
-Update Sessions Database Tables
-===============================
-
-If you are using database sessions with the CI Session Library, please
-update your ci_sessions database table as follows::
-
-	CREATE INDEX last_activity_idx ON ci_sessions(last_activity);

-=====================================
-
-This upgrade adds support for IPv6 IP addresses. In order to store them, you need
-to enlarge your ip_address columns to 45 characters. For example, CodeIgniter's
-session table will need to change
-
-::
-
-	ALTER TABLE ci_sessions CHANGE ip_address ip_address varchar(45) default '0' NOT NULL

-Before performing an update you should take your site offline by replacing the index.php file with a static one.
-
-*************************************
-Step 1: Update your CodeIgniter files
-*************************************
-
-**Replace** all files and directories in your *system/* directory and
-replace your index.php file. If any modifications were made to your
-index.php they will need to be made fresh in this new one.
-
-.. important:: You have to delete the old *system/* directory first and
-	then put the new one in its place. A simple copy-paste may cause
-	issues.
-
-.. note:: If you have any custom developed files in these folders please
-	make copies of them first.
-
-**************************************
-Step 2: Update your classes file names
-**************************************
-
-Starting with CodeIgniter 3.0, all class filenames (libraries, drivers, controllers
-and models) must be named in a Ucfirst-like manner or in other words - they must
-start with a capital letter.
-
-For example, if you have the following library file:
-
-	application/libraries/mylibrary.php
-
-... then you'll have to rename it to:
-
-	application/libraries/Mylibrary.php
-
-The same goes for driver libraries and extensions and/or overrides of CodeIgniter's
-own libraries and core classes.
-
-	application/libraries/MY_email.php  
-	application/core/MY_log.php
-
-The above files should respectively be renamed to the following:
-
-	application/libraries/MY_Email.php  
-	application/core/MY_Log.php
-
-Controllers:
-
-	application/controllers/welcome.php	->	application/controllers/Welcome.php
-
-Models:
-
-	application/models/misc_model.php	->	application/models/Misc_model.php
-
-Please note that this DOES NOT affect directories, configuration files, views,
-helpers, hooks and anything else - it is only applied to classes.
-
-You must now follow just one simple rule - class names in Ucfirst and everything else
-in lowercase.
-
-********************************
-Step 3: Replace config/mimes.php
-********************************
-
-This config file has been updated to contain more user mime-types, please copy
-it to *application/config/mimes.php*.
-
-**************************************************************
-Step 4: Remove $autoload['core'] from your config/autoload.php
-**************************************************************
-
-Use of the ``$autoload['core']`` config array has been deprecated as of CodeIgniter 1.4.1 and is now removed.
-Move any entries that you might have listed there to ``$autoload['libraries']`` instead.
-
-***************************************************
-Step 5: Move your Log class overrides or extensions
-***************************************************
-
-The Log Class is considered as a "core" class and is now located in the
-**system/core/** directory. Therefore, in order for your Log class overrides
-or extensions to work, you need to move them to **application/core/**:
-
-	application/libraries/Log.php -> application/core/Log.php  
-	application/libraries/MY_Log.php -> application/core/MY_Log.php
-
-*****************************************
-Step 6: Update your Session library usage
-*****************************************
-
-The :doc:`Session Library </libraries/sessions>` has been completely
-re-written in CodeIgniter 3 and now comes with a bunch of new features,
-but that also means that there are changes that you should make ...
-
-Most notably, the library now uses separate storage drivers instead of
-always relying on (encrypted) cookies.
-In fact, cookies as storage have now been removed and you must always use
-some kind of server-side storage engine, with the file-system being the
-default option.
-
-The Session Class now utilizes PHP's own mechanisms for building custom
-session handlers, which also means that your session data is now
-accessible via the ``$_SESSION`` superglobal (though, we've kept the
-possibility to use it as "userdata", like you've done until now).
-
-A few configuration options have been removed and a few have been added.
-You should really read the whole :doc:`Session library manual
-</libraries/sessions>` for the details, but here's a short list of changes
-that you should make:
-
-  - Set your ``$config['sess_driver']`` value
-
-    It will default to 'files', unless you've previously used
-    ``$config['sess_use_database']``, in which case it will be set to
-    'database'.
-
-  - Set a ``$config['sess_save_path']`` value
-
-    For the 'database' driver, a fallback to ``$config['sess_table_name']``
-    is in place, but otherwise requires you to read the manual for the
-    specific driver of your choice.
-
-  - Update your ``ci_sessions`` table ('database' driver only)
-
-    The table structure has changed a bit, and more specifically:
-
-      - ``session_id`` field is renamed to ``id``
-      - ``user_agent`` field is dropped
-      - ``user_data`` field is renamed to ``data`` and under MySQL is now of type BLOB
-      - ``last_activity`` field is renamed to ``timestamp``
-
-    This is accompanied by a slight change in the table indexes too, so
-    please read the manual about the `Session Database Driver
-    <../libraries/sessions.html#database-driver>`_ for more information.
-
-    .. important:: Only MySQL and PostgreSQL are officially supported
-    	now. Other databases may still work, but due to lack of advisory
-    	locking features, they are unsafe for concurrent requests and
-    	you should consider using another driver instead.
-
-  - Remove ``$config['sess_match_useragent']``
-
-    The user-agent string is input supplied by the user's browser, or in
-    other words: client side input. As such, it is an ineffective feature
-    and hence why it has been removed.
-
-  - Remove ``$config['sess_encrypt_cookie']``
-
-    As already noted, the library no longer uses cookies as a storage
-    mechanism, which renders this option useless.
-
-  - Remove ``$config['sess_expire_on_close']``
-
-    This option is still usable, but only for backwards compatibility
-    purposes and it should be otherwise removed. The same effect is
-    achieved by setting ``$config['sess_expiration']`` to 0.
-
-  - Check "flashdata" for collisions with "userdata"
-
-    Flashdata is now just regular "userdata", only marked for deletion on
-    the next request. In other words: you can't have both "userdata" and
-    "flashdata" with the same name, because it's the same thing.
-
-  - Check usage of session metadata
-
-    Previously, you could access the 'session_id', 'ip_address',
-    'user_agent' and 'last_activity' metadata items as userdata.
-    This is no longer possible, and you should read the notes about
-    `Session Metadata <../libraries/sessions.html#accessing-session-metadata>`_
-    if your application relies on those values.
-
-  - Check ``unset_userdata()`` usage
-
-    Previously, this method used to accept an associative array of
-    ``'key' => 'dummy value'`` pairs for unsetting multiple keys. That
-    however makes no sense and you now have to pass *only* the keys, as
-    the elements of an array.
-
-    ::
-
-    	// Old
-    	$this->session->unset_userdata(array('item' => '', 'item2' => ''));
-
-    	// New
-    	$this->session->unset_userdata(array('item', 'item2'));
-
-Finally, if you have written a Session extension, you must now move it to
-the *application/libraries/Session/* directory, although chances are that
-it will now also have to be re-factored.
-
-***************************************
-Step 7: Update your config/database.php
-***************************************
-
-Due to 3.0.0's renaming of Active Record to Query Builder, inside your
-**config/database.php**, you will need to rename the ``$active_record``
-variable to ``$query_builder``::
-
-	$active_group = 'default';
-	// $active_record = TRUE;
-	$query_builder = TRUE;
-
-************************************
-Step 8: Replace your error templates
-************************************
-
-In CodeIgniter 3.0, the error templates are now considered as views and have been moved to the
-*application/views/errors* directory.
-
-Furthermore, we've added support for CLI error templates in plain-text format that unlike HTML,
-is suitable for the command line. This of course requires another level of separation.
-
-It is safe to move your old templates from *application/errors* to *application/views/errors/html*,
-but you'll have to copy the new *application/views/errors/cli* directory from the CodeIgniter archive.
-
-******************************************
-Step 9: Update your config/routes.php file
-******************************************
-
-Routes containing :any
-======================
-
-Historically, CodeIgniter has always provided the **:any** wildcard in
-routing, with the intention of providing a way to match any character
-**within** an URI segment.
-
-However, the **:any** wildcard is actually just an alias for a regular
-expression and used to be executed in that manner as **.+**. This is
-considered a bug, as it also matches the / (forward slash) character, which
-is the URI segment delimiter and that was never the intention.
-
-In CodeIgniter 3, the **:any** wildcard will now represent **[^/]+**, so
-that it will not match a forward slash.
-
-There are certainly many developers that have utilized this bug as an actual
-feature. If you're one of them and want to match a forward slash, please use
-the **.+** regular expression::
-
-	(.+)	// matches ANYTHING
-	(:any)	// matches any character, except for '/'
-
-Directories and 'default_controller', '404_override'
-====================================================
-
-As you should know, the ``$route['default_controller']`` and
-``$route['404_override']`` settings accept not only a controller name, but
-also *controller/method* pairs. However, a bug in the routing logic has
-made it possible for some users to use that as *directory/controller*
-instead.
-
-As already said, this behavior was incidental and was never intended, nor
-documented. If you've relied on it, your application will break with
-CodeIgniter 3.0.
-
-Another notable change in version 3 is that 'default_controller' and
-'404_override' are now applied *per directory*. To explain what this means,
-let's take the following example::
-
-	$route['default_controller'] = 'main';
-
-Now, assuming that your website is located at *example.com*, you already
-know that if a user visits ``http://example.com/``, the above setting will
-cause your 'Main' controller to be loaded.
-
-However, what happens if you have an *application/controllers/admin/*
-directory and the user visits ``http://example.com/admin/``?
-In CodeIgniter 3, the router will look for a 'Main' controller under the
-admin/ directory as well. If not found, a Not Found (404) will be triggered.
-
-The same rule applies to the '404_override' setting.
-
-*************************************************************************
-Step 10: Many functions now return NULL instead of FALSE on missing items
-*************************************************************************
-
-Many methods and functions now return NULL instead of FALSE when the required items don't exist:
-
- - :doc:`Common functions <../general/common_functions>`
-
-   - config_item()
-
- - :doc:`Config Class <../libraries/config>`
-
-   - config->item()
-   - config->slash_item()
-
- - :doc:`Input Class <../libraries/input>`
-
-   - input->get()
-   - input->post()
-   - input->get_post()
-   - input->cookie()
-   - input->server()
-   - input->input_stream()
-   - input->get_request_header()
-
- - :doc:`Session Class <../libraries/sessions>`
-
-   - session->userdata()
-   - session->flashdata()
-
- - :doc:`URI Class <../libraries/uri>`
-
-   - uri->segment()
-   - uri->rsegment()
-
- - :doc:`Array Helper <../helpers/array_helper>`
-
-   - element()
-   - elements()
-
-*******************************
-Step 11: Usage of XSS filtering
-*******************************
-
-Many functions in CodeIgniter allow you to use its XSS filtering feature
-on demand by passing a boolean parameter. The default value of that
-parameter used to be boolean FALSE, but it is now changed to NULL and it
-will be dynamically determined by your ``$config['global_xss_filtering']``
-value.
-
-If you used to manually pass a boolean value for the ``$xss_filter``
-parameter or if you've always had ``$config['global_xss_filtering']`` set
-to FALSE, then this change doesn't concern you.
-
-Otherwise however, please review your usage of the following functions:
-
- - :doc:`Input Library <../libraries/input>`
-
-   - input->get()
-   - input->post()
-   - input->get_post()
-   - input->cookie()
-   - input->server()
-   - input->input_stream()
-
- - :doc:`Cookie Helper <../helpers/cookie_helper>` :php:func:`get_cookie()`
-
-.. important:: Another related change is that the ``$_GET``, ``$_POST``,
-	``$_COOKIE`` and ``$_SERVER`` superglobals are no longer
-	automatically overwritten when global XSS filtering is turned on.
-
-*************************************************
-Step 12: Check for potential XSS issues with URIs
-*************************************************
-
-The :doc:`URI Library <../libraries/uri>` used to automatically convert
-a certain set of "programmatic characters" to HTML entities when they
-are encountered in a URI segment.
-
-This was aimed at providing some automatic XSS protection, in addition
-to the ``$config['permitted_uri_chars']`` setting, but has proven to be
-problematic and is now removed in CodeIgniter 3.0.
-
-If your application has relied on this feature, you should update it to
-filter URI segments through ``$this->security->xss_clean()`` whenever you
-output them.
-
-****************************************************************
-Step 13: Check for usage of the 'xss_clean' Form validation rule
-****************************************************************
-
-A largely unknown rule about XSS cleaning is that it should *only be
-applied to output*, as opposed to input data.
-
-We've made that mistake ourselves with our automatic and global XSS cleaning
-feature (see previous step about XSS above), so now in an effort to discourage that
-practice, we're also removing 'xss_clean' from the officially supported
-list of :doc:`form validation <../libraries/form_validation>` rules.
-
-Because the :doc:`Form Validation library <../libraries/form_validation>`
-generally validates *input* data, the 'xss_clean' rule simply doesn't
-belong in it.
-
-If you really, really need to apply that rule, you should now also load the
-:doc:`Security Helper <../helpers/security_helper>`, which contains
-``xss_clean()`` as a regular function and therefore can be also used as
-a validation rule.
-
-********************************************************
-Step 14: Update usage of Input Class's get_post() method
-********************************************************
-
-Previously, the :doc:`Input Class <../libraries/input>` method ``get_post()``
-was searching first in POST data, then in GET data. This method has been
-modified so that it searches in GET then in POST, as its name suggests.
-
-A method has been added, ``post_get()``, which searches in POST then in GET, as
-``get_post()`` was doing before.
-
-********************************************************************
-Step 15: Update usage of Directory Helper's directory_map() function
-********************************************************************
-
-In the resulting array, directories now end with a trailing directory
-separator (i.e. a slash, usually).
-
-*************************************************************
-Step 16: Update usage of Database Forge's drop_table() method
-*************************************************************
-
-Up until now, ``drop_table()`` added an IF EXISTS clause by default or it didn't work
-at all with some drivers. In CodeIgniter 3.0, the IF EXISTS condition is no longer added
-by default and has an optional second parameter that allows that instead and is set to
-FALSE by default.
-
-If your application relies on IF EXISTS, you'll have to change its usage.
-
-::
-
-	// Now produces just DROP TABLE `table_name`
-	$this->dbforge->drop_table('table_name');
-
-	// Produces DROP TABLE IF EXISTS `table_name`
-	$this->dbforge->drop_table('table_name', TRUE);
-
-.. note:: The given example uses MySQL-specific syntax, but it should work across
-	all drivers with the exception of ODBC.
-
-***********************************************************
-Step 17: Change usage of Email library with multiple emails
-***********************************************************
-
-The :doc:`Email Library <../libraries/email>` will automatically clear the
-set parameters after successfully sending emails. To override this behaviour,
-pass FALSE as the first parameter in the ``send()`` method:
-
-::
-
-	if ($this->email->send(FALSE))
- 	{
- 		// Parameters won't be cleared
- 	}
-
-***************************************************
-Step 18: Update your Form_validation language lines
-***************************************************
-
-Two improvements have been made to the :doc:`Form Validation Library
-<../libraries/form_validation>`'s :doc:`language <../libraries/language>`
-files and error messages format:
-
- - :doc:`Language Library <../libraries/language>` line keys now must be
-   prefixed with **form_validation_** in order to avoid collisions::
-
-	// Old
-	$lang['rule'] = ...
-
-	// New
-	$lang['form_validation_rule'] = ...
-
- - The error messages format has been changed to use named parameters, to
-   allow more flexibility than what `sprintf()` offers::
-
-	// Old
-	'The %s field does not match the %s field.'
-
-	// New
-	'The {field} field does not match the {param} field.'
-
-.. note:: The old formatting still works, but the non-prefixed line keys
-	are DEPRECATED and scheduled for removal in CodeIgniter 3.1+.
-	Therefore you're encouraged to update its usage sooner rather than
-	later.
-
-************************************************************
-Step 19: Make sure your 'base_url' config value is not empty
-************************************************************
-
-When ``$config['base_url']`` is not set, CodeIgniter tries to automatically
-detect what your website's base URL is. This is done purely for convenience
-when you are starting development of a new application.
-
-Auto-detection is never reliable and also has security implications, which
-is why you should **always** have it manually configured!
-
-One of the changes in CodeIgniter 3.0.3 is how this auto-detection works,
-and more specifically it now falls back to the server's IP address instead
-of the hostname requested by the client. Therefore, if you've ever relied
-on auto-detection, it will change how your website works now.
-
-In case you need to allow e.g. multiple domains, or both http:// and
-https:// prefixes to be dynamically used depending on the request,
-remember that *application/config/config.php* is still a PHP script, in
-which you can create this logic with a few lines of code. For example::
-
-	$allowed_domains = array('domain1.tld', 'domain2.tld');
-	$default_domain  = 'domain1.tld';
-
-	if (in_array($_SERVER['HTTP_HOST'], $allowed_domains, TRUE))
-	{
-		$domain = $_SERVER['HTTP_HOST'];
-	}
-	else
-	{
-		$domain = $default_domain;
-	}
-
-	if ( ! empty($_SERVER['HTTPS']))
-	{
-		$config['base_url'] = 'https://'.$domain;
-	}
-	else
-	{
-		$config['base_url'] = 'http://'.$domain;
-	}
-
-
-****************************************************************
-Step 20: Remove usage of (previously) deprecated functionalities
-****************************************************************
-
-In addition to the ``$autoload['core']`` configuration setting, there's a
-number of other functionalities that have been removed in CodeIgniter 3.0.0:
-
-The SHA1 library
-================
-
-The previously deprecated SHA1 library has been removed, alter your code to use PHP's native
-``sha1()`` function to generate a SHA1 hash.
-
-Additionally, the ``sha1()`` method in the :doc:`Encrypt Library <../libraries/encrypt>` has been removed.
-
-The EXT constant
-================
-
-Usage of the ``EXT`` constant has been deprecated since dropping support for PHP 4. There's no
-longer a need to maintain different filename extensions and in this new CodeIgniter version,
-the ``EXT`` constant has been removed. Use just '.php' instead.
-
-Smiley helper
-=============
-
-The :doc:`Smiley Helper <../helpers/smiley_helper>` is a legacy feature from EllisLab's
-ExpressionEngine product. However, it is too specific for a general purpose framework like
-CodeIgniter and as such it is now deprecated.
-
-Also, the previously deprecated ``js_insert_smiley()`` (since version 1.7.2) is now removed.
-
-The Encrypt library
-===================
-
-Following numerous vulnerability reports, the :doc:`Encrypt Library <../libraries/encrypt>` has
-been deprecated and a new, :doc:`Encryption Library <../libraries/encryption>` is added to take
-its place.
-
-The new library requires either the `MCrypt extension <http://php.net/mcrypt>`_ (and /dev/urandom
-availability) or PHP 5.3.3 and the `OpenSSL extension <http://php.net/openssl>`_.
-While this might be rather inconvenient, it is a requirement that allows us to have properly
-implemented cryptographic functions.
-
-.. note:: The :doc:`Encrypt Library <../libraries/encrypt>` is still available for the purpose
-	of keeping backwards compatibility.
-
-.. important:: You are strongly encouraged to switch to the new :doc:`Encryption Library
-	<../libraries/encryption>` as soon as possible!
-
-The Cart library
-================
-
-The :doc:`Cart Library <../libraries/cart>`, similarly to the :doc:`Smiley Helper
-<../helpers/smiley_helper>` is too specific for CodeIgniter. It is now deprecated
-and scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: The library is still available, but you're strongly encouraged to remove its usage sooner
-	rather than later.
-
-Database drivers 'mysql', 'sqlite', 'mssql', 'pdo/dblib'
-========================================================
-
-The **mysql** driver utilizes the old 'mysql' PHP extension, known for its aging code base and
-many low-level problems. The extension is deprecated as of PHP 5.5 and CodeIgniter deprecates
-it in version 3.0, switching the default configured MySQL driver to **mysqli**.
-
-Please use either the 'mysqli' or 'pdo/mysql' drivers for MySQL. The old 'mysql' driver will be
-removed at some point in the future.
-
-The **sqlite**, **mssql** and **pdo/dblib** (also known as pdo/mssql or pdo/sybase) drivers
-all depend on PHP extensions that for different reasons no longer exist since PHP 5.3.
-
-Therefore we are now deprecating these drivers as we will have to remove them in one of the next
-CodeIgniter versions. You should use the more advanced, **sqlite3**, **sqlsrv** or **pdo/sqlsrv**
-drivers respectively.
-
-.. note:: These drivers are still available, but you're strongly encouraged to switch to other ones
-	sooner rather than later.
-
-Security helper do_hash()
-=========================
-
-:doc:`Security Helper <../helpers/security_helper>` function ``do_hash()`` is now just an alias for
-PHP's native ``hash()`` function. It is deprecated and scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
-	rather than later.
-
-The $config['global_xss_filtering'] setting
-===========================================
-
-As already explained above, XSS filtering should not be done on input data,
-but on output instead. Therefore, the ``$config['global_xss_filtering']``,
-which automatically filters *input* data, is considered a bad practice and
-is now deprecated.
-
-Instead, you should manually escape any user-provided data via the
-:php:func:`xss_clean()` function when you need to output it, or use a
-library like `HTML Purifier <http://htmlpurifier.org/>`_ that does that
-for you.
-
-.. note:: The setting is still available, but you're strongly encouraged to
-	remove its usage sooner rather than later.
-
-File helper read_file()
-=======================
-
-:doc:`File Helper <../helpers/file_helper>` function ``read_file()`` is now just an alias for
-PHP's native ``file_get_contents()`` function. It is deprecated and scheduled for removal in
-CodeIgniter 3.1+.
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
-	rather than later.
-
-String helper repeater()
-========================
-
-:doc:`String Helper <../helpers/string_helper>` function :php:func:`repeater()` is now just an alias for
-PHP's native ``str_repeat()`` function. It is deprecated and scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
-	rather than later.
-
-String helper trim_slashes()
-============================
-
-:doc:`String Helper <../helpers/string_helper>` function :php:func:`trim_slashes()` is now just an alias
-for PHP's native ``trim()`` function (with a slash passed as its second argument). It is deprecated and
-scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
-	rather than later.
-
-Form helper form_prep()
-=======================
-
-:doc:`Form Helper <../helpers/form_helper>` function :php:func:`form_prep()`
-is now just an alias for :doc:`common function </general/common_functions>`
-:func:`html_escape()`. It is deprecated and will be removed in the future.
-
-Please use :php:func:`html_escape()` instead.
-
-.. note:: This function is still available, but you're strongly encouraged
-	to remove its usage sooner rather than later.
-
-Email helper functions
-======================
-
-:doc:`Email Helper <../helpers/email_helper>` only has two functions
-
- - :php:func:`valid_email()`
- - :php:func:`send_email()`
-
-Both of them are now aliases for PHP's native ``filter_var()`` and ``mail()`` functions, respectively.
-Therefore the :doc:`Email Helper <../helpers/email_helper>` altogether is being deprecated and
-is scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: These functions are still available, but you're strongly encouraged to remove their usage
-	sooner rather than later.
-
-Date helper standard_date()
-===========================
-
-:doc:`Date Helper <../helpers/date_helper>` function ``standard_date()`` is being deprecated due
-to the availability of native PHP `constants <http://php.net/manual/en/class.datetime.php#datetime.constants.types>`_,
-which when combined with ``date()`` provide the same functionality. Furthermore, they have the
-exact same names as the ones supported by ``standard_date()``. Here are examples of how to replace
-its usage:
-
-::
-
-	// Old way
-	standard_date(); // defaults to standard_date('DATE_RFC822', now());
-
-	// Replacement
-	date(DATE_RFC822, now());
-
-	// Old way
-	standard_date('DATE_ATOM', $time);
-
-	// Replacement
-	date(DATE_ATOM, $time);
-
-.. note:: This function is still available, but you're strongly encouraged to remove its usage sooner
-	rather than later as it is scheduled for removal in CodeIgniter 3.1+.
-
-HTML helpers nbs(), br()
-========================
-
-:doc:`HTML Helper <../helpers/html_helper>` functions ``nbs()`` and ``br()`` are just aliases
-for the native ``str_repeat()`` function used with ``&nbsp;`` and ``<br >`` respectively.
-
-Because there's no point in just aliasing native PHP functions, they are now deprecated and
-scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: These functions are still available, but you're strongly encouraged to remove their usage
-	sooner rather than later.
-
-Pagination library 'anchor_class' setting
-=========================================
-
-The :doc:`Pagination Library <../libraries/pagination>` now supports adding pretty much any HTML
-attribute to your anchors via the 'attributes' configuration setting. This includes passing the
-'class' attribute and using the separate 'anchor_class' setting no longer makes sense.
-As a result of that, the 'anchor_class' setting is now deprecated and scheduled for removal in
-CodeIgniter 3.1+.
-
-.. note:: This setting is still available, but you're strongly encouraged to remove its usage sooner
-	rather than later.
-
-String helper random_string() types 'unique' and 'encrypt'
-==========================================================
-
-When using the :doc:`String Helper <../helpers/string_helper>` function :php:func:`random_string()`,
-you should no longer pass the **unique** and **encrypt** randomization types. They are only
-aliases for **md5** and **sha1** respectively and are now deprecated and scheduled for removal
-in CodeIgniter 3.1+.
-
-.. note:: These options are still available, but you're strongly encouraged to remove their usage
-	sooner rather than later.
-
-URL helper url_title() separators 'dash' and 'underscore'
-=========================================================
-
-When using the :doc:`URL Helper <../helpers/url_helper>` function :php:func:`url_title()`, you
-should no longer pass **dash** or **underscore** as the word separator. This function will
-now accept any character and you should just pass the chosen character directly, so you
-should write '-' instead of 'dash' and '_' instead of 'underscore'.
-
-**dash** and **underscore** now act as aliases and are deprecated and scheduled for removal
-in CodeIgniter 3.1+.
-
-.. note:: These options are still available, but you're strongly encouraged to remove their usage
-	sooner rather than later.
-
-Session Library method all_userdata()
-=====================================
-
-As seen in the :doc:`Change Log <../changelog>`, :doc:`Session Library <../libraries/sessions>`
-method ``userdata()`` now allows you to fetch all userdata by simply omitting its parameter::
-
-	$this->session->userdata();
-
-This makes the ``all_userdata()`` method redudant and therefore it is now just an alias for
-``userdata()`` with the above shown usage and is being deprecated and scheduled for removal
-in CodeIgniter 3.1+.
-
-.. note:: This method is still available, but you're strongly encouraged to remove its usage
-	sooner rather than later.
-
-Database Forge method add_column() with an AFTER clause
-=======================================================
-
-If you have used the **third parameter** for :doc:`Database Forge <../database/forge>` method
-``add_column()`` to add a field for an AFTER clause, then you should change its usage.
-
-That third parameter has been deprecated and scheduled for removal in CodeIgniter 3.1+.
-
-You should now put AFTER clause field names in the field definition array instead::
-
-	// Old usage:
-	$field = array(
-		'new_field' => array('type' => 'TEXT')
-	);
-
-	$this->dbforge->add_column('table_name', $field, 'another_field');
-
-	// New usage:
-	$field = array(
-		'new_field' => array('type' => 'TEXT', 'after' => 'another_field')
-	);
-
-	$this->dbforge->add_column('table_name', $field);
-
-.. note:: The parameter is still available, but you're strongly encouraged to remove its usage
-	sooner rather than later.
-
-.. note:: This is for MySQL and CUBRID databases only! Other drivers don't support this
-	clause and will silently ignore it.
-
-URI Routing methods fetch_directory(), fetch_class(), fetch_method()
-====================================================================
-
-With properties ``CI_Router::$directory``, ``CI_Router::$class`` and ``CI_Router::$method``
-being public and their respective ``fetch_*()`` no longer doing anything else to just return
-the properties - it doesn't make sense to keep them.
-
-Those are all internal, undocumented methods, but we've opted to deprecate them for now
-in order to maintain backwards-compatibility just in case. If some of you have utilized them,
-then you can now just access the properties instead::
-
-	$this->router->directory;
-	$this->router->class;
-	$this->router->method;
-
-.. note:: Those methods are still available, but you're strongly encouraged to remove their usage
-	sooner rather than later.
-
-Input library method is_cli_request()
-=====================================
-
-Calls to the ``CI_Input::is_cli_request()`` method are necessary at many places
-in the CodeIgniter internals and this is often before the :doc:`Input Library
-<../libraries/input>` is loaded. Because of that, it is being replaced by a common
-function named :php:func:`is_cli()` and this method is now just an alias.
-
-The new function is both available at all times for you to use and shorter to type.
-
-::
-
-	// Old
-	$this->input->is_cli_request();
-
-	// New
-	is_cli();
-
-``CI_Input::is_cli_request()`` is now now deprecated and scheduled for removal in
-CodeIgniter 3.1+.
-
-.. note:: This method is still available, but you're strongly encouraged to remove its usage
-	sooner rather than later.
-
-Config library method system_url()
-==================================
-
-Usage of ``CI_Config::system_url()`` encourages insecure coding practices.
-Namely, your CodeIgniter *system/* directory shouldn't be publicly accessible
-from a security point of view.
-
-Because of this, this method is now deprecated and scheduled for removal in
-CodeIgniter 3.1+.
-
-.. note:: This method is still available, but you're strongly encouraged to remove its usage
-	sooner rather than later.
-
-The Javascript library
-======================
-
-The :doc:`Javascript Library <../libraries/javascript>` has always had an
-'experimental' status and was never really useful, nor a proper solution.
-
-It is now deprecated and scheduled for removal in CodeIgniter 3.1+.
-
-.. note:: This library is still available, but you're strongly encouraged to remove its usage
-	sooner rather than later.
-
-Form Validation method prep_for_form()
-======================================
-
-The :doc:`Form Validation Library <../libraries/form_validation>` has a
-``prep_for_form()`` method, which is/can also be used as a rule in
-``set_rules()`` to automatically perform HTML encoding on input data.
-
-Automatically encoding input (instead of output) data is a bad practice in
-the first place, and CodeIgniter and PHP itself offer other alternatives
-to this method anyway.
-For example, :doc:`Form Helper <../helpers/form_helper>` functions will
-automatically perform HTML escaping when necessary.
-
-Therefore, the *prep_for_form* method/rule is pretty much useless and is now
-deprecated and scheduled for removal in 3.1+.
-
-.. note:: The method is still available, but you're strongly encouraged to
-	remove its usage sooner rather than later.
-
-***********************************************************
-Step 21: Check your usage of Text helper highlight_phrase()
-***********************************************************
-
-The default HTML tag used by :doc:`Text Helper <../helpers/text_helper>` function
-:func:`highlight_phrase()` has been changed from ``<strong>`` to the new HTML5
-tag ``<mark>``.
-
-Unless you've used your own highlighting tags, this might cause trouble
-for your visitors who use older web browsers such as Internet Explorer 8.
-We therefore suggest that you add the following code to your CSS files
-in order to avoid backwards compatibility with old browsers::
-
-	mark {
-		background: #ff0;
-		color: #000;
-	};

-Upgrading from 3.0.2 to 3.0.3
-#############################
-
-Before performing an update you should take your site offline by
-replacing the index.php file with a static one.
-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace all files and directories in your *system/* directory.
-
-.. note:: If you have any custom developed files in these directories,
-	please make copies of them first.
-
-Step 2: Make sure your 'base_url' config value is not empty
-===========================================================
-
-When ``$config['base_url']`` is not set, CodeIgniter tries to automatically
-detect what your website's base URL is. This is done purely for convenience
-when you are starting development of a new application.
-
-Auto-detection is never reliable and also has security implications, which
-is why you should **always** have it manually configured!
-
-One of the changes in CodeIgniter 3.0.3 is how this auto-detection works,
-and more specifically it now falls back to the server's IP address instead
-of the hostname requested by the client. Therefore, if you've ever relied
-on auto-detection, it will change how your website works now.
-
-In case you need to allow e.g. multiple domains, or both http:// and
-https:// prefixes to be dynamically used depending on the request,
-remember that *application/config/config.php* is still a PHP script, in
-which you can create this logic with a few lines of code. For example::
-
-	$allowed_domains = array('domain1.tld', 'domain2.tld');
-	$default_domain  = 'domain1.tld';
-
-	if (in_array($_SERVER['HTTP_HOST'], $allowed_domains, TRUE))
-	{
-		$domain = $_SERVER['HTTP_HOST'];
-	}
-	else
-	{
-		$domain = $default_domain;
-	}
-
-	if ( ! empty($_SERVER['HTTPS']))
-	{
-		$config['base_url'] = 'https://'.$domain;
-	}
-	else
-	{
-		$config['base_url'] = 'http://'.$domain;

-=====================================
-
-Replace all files and directories in your *system/* directory.
-
-.. note:: If you have any custom developed files in these directories,
-	please make copies of them first.
-
-Step 2: Check your PHP version
-==============================
-
-We recommend always running versions that are `currently supported
-<https://secure.php.net/supported-versions.php>`_, which right now is at least PHP 5.6.
-
-PHP 5.2.x versions are now officially not supported by CodeIgniter, and while 5.3.7+
-may be at least runnable, we strongly discourage you from using any PHP versions below
-the ones listed on the `PHP.net Supported Versions <https://secure.php.net/supported-versions.php>`_
-page.
-
-Step 3: If you're using the 'odbc' database driver, check for usage of Query Builder
-====================================================================================
-
-:doc:`Query Builder <../database/query_builder>` functionality and ``escape()`` can
-no longer be used with the 'odbc' database driver.
-
-This is because, due to its nature, the `ODBC extension for PHP <https://secure.php.net/odbc>`_
-does not provide a function that allows to safely escape user-supplied strings for usage
-inside an SQL query (which our :doc:`Query Builder <../database/query_builder>` relies on).
-
-Thus, user inputs MUST be bound, as shown in :doc:`Running Queries <../database/queries>`,
-under the "Query Bindings" section.

-replacing the index.php file with a static one.
-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace all files and directories in your *system/* directory.
-
-.. note:: If you have any custom developed files in these directories,
-	please make copies of them first.
-
-Step 2: Update your "ci_sessions" database table
-================================================
-
-If you're using the :doc:`Session Library </libraries/sessions>` with the
-'database' driver, you may have to ``ALTER`` your sessions table for your
-sessions to continue to work.
-
-.. note:: The table in question is not necessarily named "ci_sessions".
-	It is what you've set as your ``$config['sess_save_path']``.
-
-This will only affect you if you've changed your ``session.hash_function``
-*php.ini* setting to something like 'sha512'. Or if you've been running
-an older CodeIgniter version on PHP 7.1+.
-
-It is recommended that you do this anyway, just to avoid potential issues
-in the future if you do change your configuration.
-
-Just execute the one of the following SQL queries, depending on your
-database::
-
-	// MySQL:
-	ALTER TABLE ci_sessions CHANGE id id varchar(128) NOT NULL;
-
-	// PostgreSQL
-	ALTER TABLE ci_sessions ALTER COLUMN id SET DATA TYPE varchar(128);

-Upgrading from 3.1.2 to 3.1.3
-#############################
-
-Before performing an update you should take your site offline by
-replacing the index.php file with a static one.
-
-Step 1: Update your CodeIgniter files
-=====================================
-
-Replace all files and directories in your *system/* directory.
-
-.. note:: If you have any custom developed files in these directories,
-	please make copies of them first.
-
-Step 2: Remove usage of nice_date() helper (deprecation)
-========================================================
-
-The :doc:`Date Helper <../helpers/date_helper>` function ``nice_date()`` is
-no longer useful since the introduction of PHP's `DateTime classes
-<https://secure.php.net/datetime>`_
-
-You can replace it with the following:
-::
-
-	DateTime::createFromFormat($input_format, $input_date)->format($desired_output_format);
-
-Thus, ``nice_date()`` is now deprecated and scheduled for removal in
-CodeIgniter 3.2+.
-
-.. note:: The function is still available, but you're strongly encouraged
-	to remove its usage sooner rather than later.
-
-Step 3: Remove usage of $config['standardize_newlines']
-=======================================================
-
-The :doc:`Input Library <../libraries/input>` would optionally replace
-occurrences of `\r\n`, `\r`, `\n` in input data with whatever the ``PHP_EOL``
-value is on your system - if you've set ``$config['standardize_newlines']``
-to ``TRUE`` in your *application/config/config.php*.
-
-This functionality is now deprecated and scheduled for removal in
-CodeIgniter 3.2.+.
-
-.. note:: The functionality is still available, but you're strongly
-	encouraged to remove its usage sooner rather than later.

-###################################
-Upgrading From Beta 1.0 to Beta 1.1
-###################################
-
-To upgrade to Beta 1.1 please perform the following steps:
-
-Step 1: Replace your index file
-===============================
-
-Replace your main index.php file with the new index.php file. Note: If
-you have renamed your "system" folder you will need to edit this info in
-the new file.
-
-Step 2: Relocate your config folder
-===================================
-
-This version of CodeIgniter now permits multiple sets of "applications"
-to all share a common set of backend files. In order to enable each
-application to have its own configuration values, the config directory
-must now reside inside of your application folder, so please move it
-there.
-
-Step 3: Replace directories
-===========================
-
-Replace the following directories with the new versions:
-
--  drivers
--  helpers
--  init
--  libraries
--  scaffolding
-
-Step 4: Add the calendar language file
-======================================
-
-There is a new language file corresponding to the new calendaring class
-which must be added to your language folder. Add the following item to
-your version: language/english/calendar_lang.php
-
-Step 5: Edit your config file
-=============================
-
-The original application/config/config.php file has a typo in it Open
-the file and look for the items related to cookies::
-
-	$conf['cookie_prefix']	= "";
-	$conf['cookie_domain']	= "";
-	$conf['cookie_path']	= "/";
-
-Change the array name from $conf to $config, like this::
-
-	$config['cookie_prefix']	= "";
-	$config['cookie_domain']	= "";
-	$config['cookie_path']	= "/";
-
-Lastly, add the following new item to the config file (and edit the
-option if needed)::
-
-	
-	/*
-	|------------------------------------------------
-	| URI PROTOCOL
-	|------------------------------------------------
-	|
-	| This item determines which server global 
-	| should be used to retrieve the URI string. The 
-	| default setting of "auto" works for most servers.
-	| If your links do not seem to work, try one of 
-	| the other delicious flavors:
-	| 
-	| 'auto'	 Default - auto detects
-	| 'path_info'	 Uses the PATH_INFO 
-	| 'query_string'	Uses the QUERY_STRING
-	*/
-
-	$config['uri_protocol']	= "auto";
-

-Benchmarking Class
-##################
-
-CodeIgniter has a Benchmarking class that is always active, enabling the
-time difference between any two marked points to be calculated.
-
-.. note:: This class is initialized automatically by the system so there
-	is no need to do it manually.
-
-In addition, the benchmark is always started the moment the framework is
-invoked, and ended by the output class right before sending the final
-view to the browser, enabling a very accurate timing of the entire
-system execution to be shown.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-*************************
-Using the Benchmark Class
-*************************
-
-The Benchmark class can be used within your
-:doc:`controllers </general/controllers>`,
-:doc:`views </general/views>`, or your :doc:`models </general/models>`.
-The process for usage is this:
-
-#. Mark a start point
-#. Mark an end point
-#. Run the "elapsed time" function to view the results
-
-Here's an example using real code::
-
-	$this->benchmark->mark('code_start');
-
-	// Some code happens here
-
-	$this->benchmark->mark('code_end');
-
-	echo $this->benchmark->elapsed_time('code_start', 'code_end');
-
-.. note:: The words "code_start" and "code_end" are arbitrary. They
-	are simply words used to set two markers. You can use any words you
-	want, and you can set multiple sets of markers. Consider this example::
-
-		$this->benchmark->mark('dog');
-
-		// Some code happens here
-
-		$this->benchmark->mark('cat');
-
-		// More code happens here
-
-		$this->benchmark->mark('bird');
-
-		echo $this->benchmark->elapsed_time('dog', 'cat');
-		echo $this->benchmark->elapsed_time('cat', 'bird');
-		echo $this->benchmark->elapsed_time('dog', 'bird');
-
-
-Profiling Your Benchmark Points
-===============================
-
-If you want your benchmark data to be available to the
-:doc:`Profiler </general/profiling>` all of your marked points must
-be set up in pairs, and each mark point name must end with _start and
-_end. Each pair of points must otherwise be named identically. Example::
-
-	$this->benchmark->mark('my_mark_start');
-
-	// Some code happens here...
-
-	$this->benchmark->mark('my_mark_end');
-
-	$this->benchmark->mark('another_mark_start');
-
-	// Some more code happens here...
-
-	$this->benchmark->mark('another_mark_end');
-
-Please read the :doc:`Profiler page </general/profiling>` for more
-information.
-
-Displaying Total Execution Time
-===============================
-
-If you would like to display the total elapsed time from the moment
-CodeIgniter starts to the moment the final output is sent to the
-browser, simply place this in one of your view templates::
-
-	<?php echo $this->benchmark->elapsed_time();?>
-
-You'll notice that it's the same function used in the examples above to
-calculate the time between two point, except you are **not** using any
-parameters. When the parameters are absent, CodeIgniter does not stop
-the benchmark until right before the final output is sent to the
-browser. It doesn't matter where you use the function call, the timer
-will continue to run until the very end.
-
-An alternate way to show your elapsed time in your view files is to use
-this pseudo-variable, if you prefer not to use the pure PHP::
-
-	{elapsed_time}
-
-.. note:: If you want to benchmark anything within your controller
-	functions you must set your own start/end points.
-
-Displaying Memory Consumption
-=============================
-
-If your PHP installation is configured with --enable-memory-limit, you
-can display the amount of memory consumed by the entire system using the
-following code in one of your view file::
-
-	<?php echo $this->benchmark->memory_usage();?>
-
-.. note:: This function can only be used in your view files. The consumption
-	will reflect the total memory used by the entire app.
-
-An alternate way to show your memory usage in your view files is to use
-this pseudo-variable, if you prefer not to use the pure PHP::
-
-	{memory_usage}
-
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_Benchmark
-
-	.. php:method:: mark($name)
-
-		:param	string	$name: the name you wish to assign to your marker
-		:rtype:	void
-
-		Sets a benchmark marker.
-
-	.. php:method:: elapsed_time([$point1 = ''[, $point2 = ''[, $decimals = 4]]])
-
-		:param	string	$point1: a particular marked point
-		:param	string	$point2: a particular marked point
-		:param	int	$decimals: number of decimal places for precision
-		:returns:	Elapsed time
-		:rtype:	string
-
-		Calculates and returns the time difference between two marked points.
-
-		If the first parameter is empty this function instead returns the
-		``{elapsed_time}`` pseudo-variable. This permits the full system
-		execution time to be shown in a template. The output class will
-		swap the real value for this variable.
-
-
-	.. php:method:: memory_usage()
-
-		:returns:	Memory usage info
-		:rtype:	string
-
-		Simply returns the ``{memory_usage}`` marker.
-
-		This permits it to be put it anywhere in a template without the memory
-		being calculated until the end. The :doc:`Output Class <output>` will
-		swap the real value for this variable.

-Caching Driver
-##############
-
-CodeIgniter features wrappers around some of the most popular forms of
-fast and dynamic caching. All but file-based caching require specific
-server requirements, and a Fatal Exception will be thrown if server
-requirements are not met.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-*************
-Example Usage
-*************
-
-The following example will load the cache driver, specify `APC <#alternative-php-cache-apc-caching>`_
-as the driver to use, and fall back to file-based caching if APC is not
-available in the hosting environment.
-
-::
-
-	$this->load->driver('cache', array('adapter' => 'apc', 'backup' => 'file'));
-
-	if ( ! $foo = $this->cache->get('foo'))
-	{
-		echo 'Saving to the cache!<br />';
-		$foo = 'foobarbaz!';
-
-		// Save into the cache for 5 minutes
-		$this->cache->save('foo', $foo, 300);
-	}
-
-	echo $foo;
-
-You can also prefix cache item names via the **key_prefix** setting, which is useful
-to avoid collisions when you're running multiple applications on the same environment.
-
-::
-
-	$this->load->driver('cache',
-		array('adapter' => 'apc', 'backup' => 'file', 'key_prefix' => 'my_')

-Drivers
-*******
-
-Alternative PHP Cache (APC) Caching
-===================================
-
-All of the methods listed above can be accessed without passing a
-specific adapter to the driver loader as follows::
-
-	$this->load->driver('cache');
-	$this->cache->apc->save('foo', 'bar', 10);
-
-For more information on APC, please see
-`http://php.net/apc <http://php.net/apc>`_.
-
-File-based Caching
-==================
-
-Unlike caching from the Output Class, the driver file-based caching
-allows for pieces of view files to be cached. Use this with care, and
-make sure to benchmark your application, as a point can come where disk
-I/O will negate positive gains by caching.
-
-All of the methods listed above can be accessed without passing a
-specific adapter to the driver loader as follows::
-
-	$this->load->driver('cache');
-	$this->cache->file->save('foo', 'bar', 10);
-
-Memcached Caching
-=================
-
-Multiple Memcached servers can be specified in the memcached.php
-configuration file, located in the _application/config/* directory.
-
-All of the methods listed above can be accessed without passing a
-specific adapter to the driver loader as follows::
-
-	$this->load->driver('cache');
-	$this->cache->memcached->save('foo', 'bar', 10);
-
-For more information on Memcached, please see
-`http://php.net/memcached <http://php.net/memcached>`_.
-
-WinCache Caching
-================
-
-Under Windows, you can also utilize the WinCache driver.
-
-All of the methods listed above can be accessed without passing a
-specific adapter to the driver loader as follows::
-
-	$this->load->driver('cache');
-	$this->cache->wincache->save('foo', 'bar', 10);
-
-For more information on WinCache, please see
-`http://php.net/wincache <http://php.net/wincache>`_.
-
-Redis Caching
-=============
-
-Redis is an in-memory key-value store which can operate in LRU cache mode. 
-To use it, you need `Redis server and phpredis PHP extension <https://github.com/phpredis/phpredis>`_.
-
-Config options to connect to redis server must be stored in the application/config/redis.php file.
-Available options are::
-	
-	$config['socket_type'] = 'tcp'; //`tcp` or `unix`
-	$config['socket'] = '/var/run/redis.sock'; // in case of `unix` socket type
-	$config['host'] = '127.0.0.1';
-	$config['password'] = NULL;
-	$config['port'] = 6379;
-	$config['timeout'] = 0;
-
-All of the methods listed above can be accessed without passing a
-specific adapter to the driver loader as follows::
-
-	$this->load->driver('cache');
-	$this->cache->redis->save('foo', 'bar', 10);
-
-For more information on Redis, please see
-`http://redis.io <http://redis.io>`_.
-
-Dummy Cache
-===========
-
-This is a caching backend that will always 'miss.' It stores no data,
-but lets you keep your caching code in place in environments that don't
-support your chosen cache.

-Calendaring Class
-#################
-
-The Calendar class enables you to dynamically create calendars. Your
-calendars can be formatted through the use of a calendar template,
-allowing 100% control over every aspect of its design. In addition, you
-can pass data to your calendar cells.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-***************************
-Using the Calendaring Class
-***************************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Calendar class is
-initialized in your controller using the $this->load->library function::
-
-	$this->load->library('calendar');
-
-Once loaded, the Calendar object will be available using::
-
-	$this->calendar
-
-Displaying a Calendar
-=====================
-
-Here is a very simple example showing how you can display a calendar::
-
-	$this->load->library('calendar');
-	echo $this->calendar->generate();
-
-The above code will generate a calendar for the current month/year based
-on your server time. To show a calendar for a specific month and year
-you will pass this information to the calendar generating function::
-
-	$this->load->library('calendar');
-	echo $this->calendar->generate(2006, 6);
-
-The above code will generate a calendar showing the month of June in
-2006. The first parameter specifies the year, the second parameter
-specifies the month.
-
-Passing Data to your Calendar Cells
-===================================
-
-To add data to your calendar cells involves creating an associative
-array in which the keys correspond to the days you wish to populate and
-the array value contains the data. The array is passed to the third
-parameter of the calendar generating function. Consider this example::
-
-	$this->load->library('calendar');
-
-	$data = array(
-		3  => 'http://example.com/news/article/2006/06/03/',
-		7  => 'http://example.com/news/article/2006/06/07/',
-		13 => 'http://example.com/news/article/2006/06/13/',
-		26 => 'http://example.com/news/article/2006/06/26/'
-	);
-
-	echo $this->calendar->generate(2006, 6, $data);
-
-Using the above example, day numbers 3, 7, 13, and 26 will become links
-pointing to the URLs you've provided.
-
-.. note:: By default it is assumed that your array will contain links.
-	In the section that explains the calendar template below you'll see how
-	you can customize how data passed to your cells is handled so you can
-	pass different types of information.
-
-Setting Display Preferences
-===========================
-
-There are seven preferences you can set to control various aspects of
-the calendar. Preferences are set by passing an array of preferences in
-the second parameter of the loading function. Here is an example::
-
-	$prefs = array(
-		'start_day'    => 'saturday',
-		'month_type'   => 'long',
-		'day_type'     => 'short'
-	);
-
-	$this->load->library('calendar', $prefs);
-
-	echo $this->calendar->generate();
-
-The above code would start the calendar on saturday, use the "long"
-month heading, and the "short" day names. More information regarding
-preferences below.
-
-======================  =================  ============================================  ===================================================================
-Preference              Default            Options                                       Description
-======================  =================  ============================================  ===================================================================
-**template**           	None               None                                          A string or array containing your calendar template.
-											   See the template section below.
-**local_time**        	time()             None                                          A Unix timestamp corresponding to the current time.
-**start_day**           sunday             Any week day (sunday, monday, tuesday, etc.)  Sets the day of the week the calendar should start on.
-**month_type**          long               long, short                                   Determines what version of the month name to use in the header.
-											   long = January, short = Jan.
-**day_type**            abr                long, short, abr                              Determines what version of the weekday names to use in
-											   the column headers. long = Sunday, short = Sun, abr = Su.
-**show_next_prev**      FALSE              TRUE/FALSE (boolean)                          Determines whether to display links allowing you to toggle
-											   to next/previous months. See information on this feature below.
-**next_prev_url**       controller/method  A URL                                         Sets the basepath used in the next/previous calendar links.
-**show_other_days**     FALSE              TRUE/FALSE (boolean)                          Determines whether to display days of other months that share the
-											   first or last week of the calendar month.
-======================  =================  ============================================  ===================================================================
-
-
-Showing Next/Previous Month Links
-=================================
-
-To allow your calendar to dynamically increment/decrement via the
-next/previous links requires that you set up your calendar code similar
-to this example::
-
-	$prefs = array(
-		'show_next_prev'  => TRUE,
-		'next_prev_url'   => 'http://example.com/index.php/calendar/show/'
-	);
-
-	$this->load->library('calendar', $prefs);
-
-	echo $this->calendar->generate($this->uri->segment(3), $this->uri->segment(4));
-
-You'll notice a few things about the above example:
-
--  You must set the "show_next_prev" to TRUE.
--  You must supply the URL to the controller containing your calendar in
-   the "next_prev_url" preference. If you don't, it will be set to the current
-   *controller/method*.
--  You must supply the "year" and "month" to the calendar generating
-   function via the URI segments where they appear (Note: The calendar
-   class automatically adds the year/month to the base URL you
-   provide.).
-
-Creating a Calendar Template
-============================
-
-By creating a calendar template you have 100% control over the design of
-your calendar. Using the string method, each component of your calendar
-will be placed within a pair of pseudo-variables as shown here::
-
-	$prefs['template'] = '
-
-		{table_open}<table border="0" cellpadding="0" cellspacing="0">{/table_open}
-
-		{heading_row_start}<tr>{/heading_row_start}
-
-		{heading_previous_cell}<th><a href="{previous_url}">&lt;&lt;</a></th>{/heading_previous_cell}
-		{heading_title_cell}<th colspan="{colspan}">{heading}</th>{/heading_title_cell}
-		{heading_next_cell}<th><a href="{next_url}">&gt;&gt;</a></th>{/heading_next_cell}
-
-		{heading_row_end}</tr>{/heading_row_end}
-
-		{week_row_start}<tr>{/week_row_start}
-		{week_day_cell}<td>{week_day}</td>{/week_day_cell}
-		{week_row_end}</tr>{/week_row_end}
-
-		{cal_row_start}<tr>{/cal_row_start}
-		{cal_cell_start}<td>{/cal_cell_start}
-		{cal_cell_start_today}<td>{/cal_cell_start_today}
-		{cal_cell_start_other}<td class="other-month">{/cal_cell_start_other}
-
-		{cal_cell_content}<a href="{content}">{day}</a>{/cal_cell_content}
-		{cal_cell_content_today}<div class="highlight"><a href="{content}">{day}</a></div>{/cal_cell_content_today}
-
-		{cal_cell_no_content}{day}{/cal_cell_no_content}
-		{cal_cell_no_content_today}<div class="highlight">{day}</div>{/cal_cell_no_content_today}
-
-		{cal_cell_blank}&nbsp;{/cal_cell_blank}
-
-		{cal_cell_other}{day}{/cal_cel_other}
-
-		{cal_cell_end}</td>{/cal_cell_end}
-		{cal_cell_end_today}</td>{/cal_cell_end_today}
-		{cal_cell_end_other}</td>{/cal_cell_end_other}
-		{cal_row_end}</tr>{/cal_row_end}
-
-		{table_close}</table>{/table_close}
-	';
-
-	$this->load->library('calendar', $prefs);
-
-	echo $this->calendar->generate();
-
-Using the array method, you will pass `key => value` pairs. You can pass as
-many or as few values as you'd like. Omitted keys will use the default values
-inherited in the calendar class.
-
-Example::
-
-	$prefs['template'] = array(
-		'table_open'           => '<table class="calendar">',
-		'cal_cell_start'       => '<td class="day">',
-		'cal_cell_start_today' => '<td class="today">'
-	);
-    
-	$this->load->library('calendar', $prefs);
-    
-	echo $this->calendar->generate();

-Shopping Cart Class
-###################
-
-The Cart Class permits items to be added to a session that stays active
-while a user is browsing your site. These items can be retrieved and
-displayed in a standard "shopping cart" format, allowing the user to
-update the quantity or remove items from the cart.
-
-.. important:: The Cart library is DEPRECATED and should not be used. 
-	It is currently only kept for backwards compatibility.
-
-Please note that the Cart Class ONLY provides the core "cart"
-functionality. It does not provide shipping, credit card authorization,
-or other processing components.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-********************
-Using the Cart Class
-********************
-
-Initializing the Shopping Cart Class
-====================================
-
-.. important:: The Cart class utilizes CodeIgniter's :doc:`Session
-	Class <sessions>` to save the cart information to a database, so
-	before using the Cart class you must set up a database table as
-	indicated in the :doc:`Session Documentation <sessions>`, and set the
-	session preferences in your application/config/config.php file to
-	utilize a database.
-
-To initialize the Shopping Cart Class in your controller constructor,
-use the ``$this->load->library()`` method::
-
-	$this->load->library('cart');
-
-Once loaded, the Cart object will be available using::
-
-	$this->cart
-
-.. note:: The Cart Class will load and initialize the Session Class
-	automatically, so unless you are using sessions elsewhere in your
-	application, you do not need to load the Session class.
-
-Adding an Item to The Cart
-==========================
-
-To add an item to the shopping cart, simply pass an array with the
-product information to the ``$this->cart->insert()`` method, as shown
-below::
-
-	$data = array(
-		'id'      => 'sku_123ABC',
-		'qty'     => 1,
-		'price'   => 39.95,
-		'name'    => 'T-Shirt',
-		'options' => array('Size' => 'L', 'Color' => 'Red')
-	);
-
-	$this->cart->insert($data);
-
-.. important:: The first four array indexes above (id, qty, price, and
-	name) are **required**. If you omit any of them the data will not be
-	saved to the cart. The fifth index (options) is optional. It is intended
-	to be used in cases where your product has options associated with it.
-	Use an array for options, as shown above.
-
-The five reserved indexes are:
-
--  **id** - Each product in your store must have a unique identifier.
-   Typically this will be an "sku" or other such identifier.
--  **qty** - The quantity being purchased.
--  **price** - The price of the item.
--  **name** - The name of the item.
--  **options** - Any additional attributes that are needed to identify
-   the product. These must be passed via an array.
-
-In addition to the five indexes above, there are two reserved words:
-rowid and subtotal. These are used internally by the Cart class, so
-please do NOT use those words as index names when inserting data into
-the cart.
-
-Your array may contain additional data. Anything you include in your
-array will be stored in the session. However, it is best to standardize
-your data among all your products in order to make displaying the
-information in a table easier.
-
-::
-
-	$data = array(
-		'id'      => 'sku_123ABC',
-		'qty'     => 1,
-		'price'   => 39.95,
-		'name'    => 'T-Shirt',
-		'coupon'	 => 'XMAS-50OFF'
-	);
-
-	$this->cart->insert($data);
-
-The ``insert()`` method will return the $rowid if you successfully insert a
-single item.
-
-Adding Multiple Items to The Cart
-=================================
-
-By using a multi-dimensional array, as shown below, it is possible to
-add multiple products to the cart in one action. This is useful in cases
-where you wish to allow people to select from among several items on the
-same page.
-
-::
-
-	$data = array(
-		array(
-			'id'      => 'sku_123ABC',
-			'qty'     => 1,
-			'price'   => 39.95,
-			'name'    => 'T-Shirt',
-			'options' => array('Size' => 'L', 'Color' => 'Red')
-		),
-		array(
-			'id'      => 'sku_567ZYX',
-			'qty'     => 1,
-			'price'   => 9.95,
-			'name'    => 'Coffee Mug'
-		),
-		array(
-			'id'      => 'sku_965QRS',
-			'qty'     => 1,
-			'price'   => 29.95,
-			'name'    => 'Shot Glass'
-		)
-	);
-
-	$this->cart->insert($data);
-
-Displaying the Cart
-===================
-
-To display the cart you will create a :doc:`view
-file </general/views>` with code similar to the one shown below.
-
-Please note that this example uses the :doc:`form
-helper </helpers/form_helper>`.
-
-::
-
-	<?php echo form_open('path/to/controller/update/method'); ?>
-
-	<table cellpadding="6" cellspacing="1" style="width:100%" border="0">
-
-	<tr>
-		<th>QTY</th>
-		<th>Item Description</th>
-		<th style="text-align:right">Item Price</th>
-		<th style="text-align:right">Sub-Total</th>
-	</tr>
-
-	<?php $i = 1; ?>
-
-	<?php foreach ($this->cart->contents() as $items): ?>
-
-		<?php echo form_hidden($i.'[rowid]', $items['rowid']); ?>
-
-		<tr>
-			<td><?php echo form_input(array('name' => $i.'[qty]', 'value' => $items['qty'], 'maxlength' => '3', 'size' => '5')); ?></td>
-			<td>
-				<?php echo $items['name']; ?>
-
-				<?php if ($this->cart->has_options($items['rowid']) == TRUE): ?>
-
-					<p>
-						<?php foreach ($this->cart->product_options($items['rowid']) as $option_name => $option_value): ?>
-
-							<strong><?php echo $option_name; ?>:</strong> <?php echo $option_value; ?><br />
-
-						<?php endforeach; ?>
-					</p>
-
-				<?php endif; ?>
-
-			</td>
-			<td style="text-align:right"><?php echo $this->cart->format_number($items['price']); ?></td>
-			<td style="text-align:right">$<?php echo $this->cart->format_number($items['subtotal']); ?></td>
-		</tr>
-
-	<?php $i++; ?>
-
-	<?php endforeach; ?>
-
-	<tr>
-		<td colspan="2"> </td>
-		<td class="right"><strong>Total</strong></td>
-		<td class="right">$<?php echo $this->cart->format_number($this->cart->total()); ?></td>
-	</tr>
-
-	</table>
-
-	<p><?php echo form_submit('', 'Update your Cart'); ?></p>
-
-Updating The Cart
-=================
-
-To update the information in your cart, you must pass an array
-containing the Row ID and one or more pre-defined properties to the 
-``$this->cart->update()`` method.
-
-.. note:: If the quantity is set to zero, the item will be removed from
-	the cart.
-
-::
-
-	$data = array(
-		'rowid' => 'b99ccdf16028f015540f341130b6d8ec',
-		'qty'   => 3
-	);
-
-	$this->cart->update($data);
-
-	// Or a multi-dimensional array
-
-	$data = array(
-		array(
-			'rowid'   => 'b99ccdf16028f015540f341130b6d8ec',
-			'qty'     => 3
-		),
-		array(
-			'rowid'   => 'xw82g9q3r495893iajdh473990rikw23',
-			'qty'     => 4
-		),
-		array(
-			'rowid'   => 'fh4kdkkkaoe30njgoe92rkdkkobec333',
-			'qty'     => 2
-		)
-	);
-
-	$this->cart->update($data);
-
-You may also update any property you have previously defined when
-inserting the item such as options, price or other custom fields.
-
-::
-
-	$data = array(
-		'rowid'  => 'b99ccdf16028f015540f341130b6d8ec',
-		'qty'    => 1,
-		'price'	 => 49.95,
-		'coupon' => NULL
-	);
-
-	$this->cart->update($data);
-
-What is a Row ID?
-*****************
-
-The row ID is a unique identifier that is generated by the cart code
-when an item is added to the cart. The reason a unique ID is created
-is so that identical products with different options can be managed
-by the cart.
-
-For example, let's say someone buys two identical t-shirts (same product
-ID), but in different sizes. The product ID (and other attributes) will
-be identical for both sizes because it's the same shirt. The only
-difference will be the size. The cart must therefore have a means of
-identifying this difference so that the two sizes of shirts can be
-managed independently. It does so by creating a unique "row ID" based on
-the product ID and any options associated with it.
-
-In nearly all cases, updating the cart will be something the user does
-via the "view cart" page, so as a developer, it is unlikely that you
-will ever have to concern yourself with the "row ID", other than making
-sure your "view cart" page contains this information in a hidden form
-field, and making sure it gets passed to the ``update()`` method when
-the update form is submitted. Please examine the construction of the
-"view cart" page above for more information.
-
-

-Config Class
-############
-
-The Config class provides a means to retrieve configuration preferences.
-These preferences can come from the default config file
-(application/config/config.php) or from your own custom config files.
-
-.. note:: This class is initialized automatically by the system so there
-	is no need to do it manually.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-*****************************
-Working with the Config Class
-*****************************
-
-Anatomy of a Config File
-========================
-
-By default, CodeIgniter has one primary config file, located at
-application/config/config.php. If you open the file using your text
-editor you'll see that config items are stored in an array called
-$config.
-
-You can add your own config items to this file, or if you prefer to keep
-your configuration items separate (assuming you even need config items),
-simply create your own file and save it in config folder.
-
-.. note:: If you do create your own config files use the same format as
-	the primary one, storing your items in an array called $config.
-	CodeIgniter will intelligently manage these files so there will be no
-	conflict even though the array has the same name (assuming an array
-	index is not named the same as another).
-
-Loading a Config File
-=====================
-
-.. note::
-	CodeIgniter automatically loads the primary config file
-	(application/config/config.php), so you will only need to load a config
-	file if you have created your own.
-
-There are two ways to load a config file:
-
-Manual Loading
-**************
-
-To load one of your custom config files you will use the following
-function within the :doc:`controller </general/controllers>` that
-needs it::
-
-	$this->config->load('filename');
-
-Where filename is the name of your config file, without the .php file
-extension.
-
-If you need to load multiple config files normally they will be
-merged into one master config array. Name collisions can occur,
-however, if you have identically named array indexes in different
-config files. To avoid collisions you can set the second parameter to
-TRUE and each config file will be stored in an array index
-corresponding to the name of the config file. Example::
-
-	// Stored in an array with this prototype: $this->config['blog_settings'] = $config
-	$this->config->load('blog_settings', TRUE);
-
-Please see the section entitled Fetching Config Items below to learn
-how to retrieve config items set this way.
-
-The third parameter allows you to suppress errors in the event that a
-config file does not exist::
-
-	$this->config->load('blog_settings', FALSE, TRUE);
-
-Auto-loading
-************
-
-If you find that you need a particular config file globally, you can
-have it loaded automatically by the system. To do this, open the
-**autoload.php** file, located at application/config/autoload.php,
-and add your config file as indicated in the file.
-
-
-Fetching Config Items
-=====================
-
-To retrieve an item from your config file, use the following function::
-
-	$this->config->item('item_name');
-
-Where item_name is the $config array index you want to retrieve. For
-example, to fetch your language choice you'll do this::
-
-	$lang = $this->config->item('language');
-
-The function returns NULL if the item you are trying to fetch
-does not exist.
-
-If you are using the second parameter of the $this->config->load
-function in order to assign your config items to a specific index you
-can retrieve it by specifying the index name in the second parameter of
-the $this->config->item() function. Example::
-
-	// Loads a config file named blog_settings.php and assigns it to an index named "blog_settings"
-	$this->config->load('blog_settings', TRUE);
-
-	// Retrieve a config item named site_name contained within the blog_settings array
-	$site_name = $this->config->item('site_name', 'blog_settings');
-
-	// An alternate way to specify the same item:
-	$blog_config = $this->config->item('blog_settings');
-	$site_name = $blog_config['site_name'];
-
-Setting a Config Item
-=====================
-
-If you would like to dynamically set a config item or change an existing
-one, you can do so using::
-
-	$this->config->set_item('item_name', 'item_value');
-
-Where item_name is the $config array index you want to change, and
-item_value is its value.
-
-.. _config-environments:
-
-Environments
-============
-
-You may load different configuration files depending on the current
-environment. The ENVIRONMENT constant is defined in index.php, and is
-described in detail in the :doc:`Handling
-Environments </general/environments>` section.
-
-To create an environment-specific configuration file, create or copy a
-configuration file in application/config/{ENVIRONMENT}/{FILENAME}.php
-
-For example, to create a production-only config.php, you would:
-
-#. Create the directory application/config/production/
-#. Copy your existing config.php into the above directory
-#. Edit application/config/production/config.php so it contains your
-   production settings
-
-When you set the ENVIRONMENT constant to 'production', the settings for
-your new production-only config.php will be loaded.
-
-You can place the following configuration files in environment-specific
-folders:
-
--  Default CodeIgniter configuration files
--  Your own custom configuration files
-
-.. note::
-	CodeIgniter always loads the global config file first (i.e., the one in application/config/),
-	then tries to load the configuration files for the current environment.
-	This means you are not obligated to place **all** of your configuration files in an
-	environment folder. Only the files that change per environment. Additionally you don't
-	have to copy **all** the config items in the environment config file. Only the config items
-	that you wish to change for your environment. The config items declared in your environment
-	folders always overwrite those in your global config files.

-***********************
-Using the Email Library
-***********************
-
-Sending Email
-=============
-
-Sending email is not only simple, but you can configure it on the fly or
-set your preferences in a config file.
-
-Here is a basic example demonstrating how you might send email. Note:
-This example assumes you are sending the email from one of your
-:doc:`controllers <../general/controllers>`.
-
-::
-
-	$this->load->library('email');
-
-	$this->email->from('your@example.com', 'Your Name');
-	$this->email->to('someone@example.com');
-	$this->email->cc('another@another-example.com');
-	$this->email->bcc('them@their-example.com');
-
-	$this->email->subject('Email Test');
-	$this->email->message('Testing the email class.');
-
-	$this->email->send();
-
-Setting Email Preferences
-=========================
-
-There are 21 different preferences available to tailor how your email
-messages are sent. You can either set them manually as described here,
-or automatically via preferences stored in your config file, described
-below:
-
-Preferences are set by passing an array of preference values to the
-email initialize method. Here is an example of how you might set some
-preferences::
-
-	$config['protocol'] = 'sendmail';
-	$config['mailpath'] = '/usr/sbin/sendmail';
-	$config['charset'] = 'iso-8859-1';
-	$config['wordwrap'] = TRUE;
-
-	$this->email->initialize($config);
-
-.. note:: Most of the preferences have default values that will be used
-	if you do not set them.
-
-Setting Email Preferences in a Config File
-------------------------------------------
-
-If you prefer not to set preferences using the above method, you can
-instead put them into a config file. Simply create a new file called the
-email.php, add the $config array in that file. Then save the file at
-config/email.php and it will be used automatically. You will NOT need to
-use the ``$this->email->initialize()`` method if you save your
-preferences in a config file.
-
-Email Preferences

-
-The following is a list of all the preferences that can be set when
-sending email.

-=================== ====================== ============================ =======================================================================
-
-Overriding Word Wrapping
-========================
-
-If you have word wrapping enabled (recommended to comply with RFC 822)
-and you have a very long link in your email it can get wrapped too,
-causing it to become un-clickable by the person receiving it.
-CodeIgniter lets you manually override word wrapping within part of your
-message like this::
-
-	The text of your email that
-	gets wrapped normally.
-
-	{unwrap}http://example.com/a_long_link_that_should_not_be_wrapped.html{/unwrap}
-
-	More text that will be
-	wrapped normally.
-
-
-Place the item you do not want word-wrapped between: {unwrap} {/unwrap}

-
-		Returns a string containing any server messages, the email headers, and
-		the email message. Useful for debugging.
-
-		You can optionally specify which parts of the message should be printed.
-		Valid options are: **headers**, **subject**, **body**.
-
-		Example::
-
-			// You need to pass FALSE while sending in order for the email data
-			// to not be cleared - if that happens, print_debugger() would have
-			// nothing to output.
-			$this->email->send(FALSE);
-

-Encrypt Class
-#############
-
-The Encrypt Class provides two-way data encryption. It encrypted using
-the Mcrypt PHP extension, which is required for the Encrypt Class to run.
-
-.. important:: This library has been DEPRECATED and is only kept for
-	backwards compatibility. Please use the new :doc:`Encryption Library
-	<encryption>`.

-*************************
-Using the Encrypt Library
-*************************
-
-Setting your Key
-================
-
-A *key* is a piece of information that controls the cryptographic
-process and permits an encrypted string to be decoded. In fact, the key
-you chose will provide the **only** means to decode data that was
-encrypted with that key, so not only must you choose the key carefully,
-you must never change it if you intend use it for persistent data.
-
-It goes without saying that you should guard your key carefully. Should
-someone gain access to your key, the data will be easily decoded. If
-your server is not totally under your control it's impossible to ensure
-key security so you may want to think carefully before using it for
-anything that requires high security, like storing credit card numbers.
-
-To take maximum advantage of the encryption algorithm, your key should
-be 32 characters in length (256 bits). The key should be as random a
-string as you can concoct, with numbers and uppercase and lowercase
-letters. Your key should **not** be a simple text string. In order to be
-cryptographically secure it needs to be as random as possible.
-
-Your key can be either stored in your **application/config/config.php**, or
-you can design your own storage mechanism and pass the key dynamically
-when encoding/decoding.
-
-To save your key to your **application/config/config.php**, open the file
-and set::
-
-	$config['encryption_key'] = "YOUR KEY";
-
-Message Length
-==============
-
-It's important for you to know that the encoded messages the encryption
-function generates will be approximately 2.6 times longer than the
-original message. For example, if you encrypt the string "my super
-secret data", which is 21 characters in length, you'll end up with an
-encoded string that is roughly 55 characters (we say "roughly" because
-the encoded string length increments in 64 bit clusters, so it's not
-exactly linear). Keep this information in mind when selecting your data
-storage mechanism. Cookies, for example, can only hold 4K of
-information.
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Encrypt class is
-initialized in your controller using the ``$this->load->library()``
-method::
-
-	$this->load->library('encrypt');
-
-Once loaded, the Encrypt library object will be available using::
-
-	$this->encrypt
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_Encrypt
-
-	.. php:method:: encode($string[, $key = ''])
-
-		:param	string	$string: Data to encrypt
-		:param	string	$key: Encryption key
-		:returns:	Encrypted string
-		:rtype:	string
-
-		Performs the data encryption and returns it as a string. Example::
-
-			$msg = 'My secret message';
-
-			$encrypted_string = $this->encrypt->encode($msg);
-
-		You can optionally pass your encryption key via the second parameter if
-		you don't want to use the one in your config file::
-
-			$msg = 'My secret message';
-			$key = 'super-secret-key';
-
-			$encrypted_string = $this->encrypt->encode($msg, $key);
-
-	.. php:method:: decode($string[, $key = ''])
-
-		:param	string	$string: String to decrypt
-		:param	string	$key: Encryption key
-		:returns:	Plain-text string
-		:rtype:	string
-
-		Decrypts an encoded string. Example::
-
-			$encrypted_string = 'APANtByIGI1BpVXZTJgcsAG8GZl8pdwwa84';
-
-			$plaintext_string = $this->encrypt->decode($encrypted_string);
-
-		You can optionally pass your encryption key via the second parameter if
-		you don't want to use the one in your config file::
-
-			$msg = 'My secret message';
-			$key = 'super-secret-key';
-
-			$encrypted_string = $this->encrypt->decode($msg, $key);
-
-	.. php:method:: set_cipher($cipher)
-
-		:param	int	$cipher: Valid PHP MCrypt cypher constant
-		:returns:	CI_Encrypt instance (method chaining)
-		:rtype:	CI_Encrypt
-
-		Permits you to set an Mcrypt cipher. By default it uses
-		``MCRYPT_RIJNDAEL_256``. Example::
-
-			$this->encrypt->set_cipher(MCRYPT_BLOWFISH);
-
-		Please visit php.net for a list of `available ciphers <http://php.net/mcrypt>`_.
-
-		If you'd like to manually test whether your server supports MCrypt you
-		can use::
-
-			echo extension_loaded('mcrypt') ? 'Yup' : 'Nope';
-
-	.. php:method:: set_mode($mode)
-
-		:param	int	$mode: Valid PHP MCrypt mode constant
-		:returns:	CI_Encrypt instance (method chaining)
-		:rtype:	CI_Encrypt
-
-		Permits you to set an Mcrypt mode. By default it uses **MCRYPT_MODE_CBC**.
-		Example::
-
-			$this->encrypt->set_mode(MCRYPT_MODE_CFB);
-
-		Please visit php.net for a list of `available modes <http://php.net/mcrypt>`_.
-
-	.. php:method:: encode_from_legacy($string[, $legacy_mode = MCRYPT_MODE_ECB[, $key = '']])
-
-		:param	string	$string: String to encrypt
-		:param	int	$legacy_mode: Valid PHP MCrypt cipher constant
-		:param	string	$key: Encryption key
-		:returns:	Newly encrypted string
-		:rtype:	string
-
-		Enables you to re-encode data that was originally encrypted with
-		CodeIgniter 1.x to be compatible with the Encrypt library in
-		CodeIgniter 2.x. It is only necessary to use this method if you have
-		encrypted data stored permanently such as in a file or database and are
-		on a server that supports Mcrypt. "Light" use encryption such as
-		encrypted session data or transitory encrypted flashdata require no
-		intervention on your part. However, existing encrypted Sessions will be
-		destroyed since data encrypted prior to 2.x will not be decoded.
-
-		.. important::
-			**Why only a method to re-encode the data instead of maintaining legacy
-			methods for both encoding and decoding?** The algorithms in the
-			Encrypt library have improved in CodeIgniter 2.x both for performance
-			and security, and we do not wish to encourage continued use of the older
-			methods. You can of course extend the Encryption library if you wish and
-			replace the new methods with the old and retain seamless compatibility
-			with CodeIgniter 1.x encrypted data, but this a decision that a
-			developer should make cautiously and deliberately, if at all.
-
-		::
-
-			$new_data = $this->encrypt->encode_from_legacy($old_encrypted_string);

-Encryption Library
-##################
-
-.. important:: DO NOT use this or any other *encryption* library for
-	user password storage! Passwords must be *hashed* instead, and you
-	should do that via PHP's own `Password Hashing extension
-	<http://php.net/password>`_.
-
-The Encryption Library provides two-way data encryption. To do so in
-a cryptographically secure way, it utilizes PHP extensions that are
-unfortunately not always available on all systems.
-You must meet one of the following dependencies in order to use this
-library:
-
-- `OpenSSL <http://php.net/openssl>`_
-- `MCrypt <http://php.net/mcrypt>`_ (and `MCRYPT_DEV_URANDOM` availability)
-
-If neither of the above dependencies is met, we simply cannot offer
-you a good enough implementation to meet the high standards required
-for proper cryptography.

-****************************
-Using the Encryption Library
-****************************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Encryption library is
-initialized in your controller using the ``$this->load->library()``
-method::
-
-	$this->load->library('encryption');
-
-Once loaded, the Encryption library object will be available using::
-
-	$this->encryption
-
-Default behavior
-================
-
-By default, the Encryption Library will use the AES-128 cipher in CBC
-mode, using your configured *encryption_key* and SHA512 HMAC authentication.
-
-.. note:: AES-128 is chosen both because it is proven to be strong and
-	because of its wide availability across different cryptographic
-	software and programming languages' APIs.
-
-However, the *encryption_key* is not used as is.
-
-If you are somewhat familiar with cryptography, you should already know
-that a HMAC also requires a secret key and using the same key for both
-encryption and authentication is a bad practice.
-
-Because of that, two separate keys are derived from your already configured
-*encryption_key*: one for encryption and one for authentication. This is
-done via a technique called `HMAC-based Key Derivation Function
-<http://en.wikipedia.org/wiki/HKDF>`_ (HKDF).
-
-Setting your encryption_key
-===========================
-
-An *encryption key* is a piece of information that controls the
-cryptographic process and permits a plain-text string to be encrypted,
-and afterwards - decrypted. It is the secret "ingredient" in the whole
-process that allows you to be the only one who is able to decrypt data
-that you've decided to hide from the eyes of the public.
-After one key is used to encrypt data, that same key provides the **only**
-means to decrypt it, so not only must you chose one carefully, but you
-must not lose it or you will also lose access to the data.
-
-It must be noted that to ensure maximum security, such key *should* not
-only be as strong as possible, but also often changed. Such behavior
-however is rarely practical or possible to implement, and that is why
-CodeIgniter gives you the ability to configure a single key that is to be
-used (almost) every time.
-
-It goes without saying that you should guard your key carefully. Should
-someone gain access to your key, the data will be easily decrypted. If
-your server is not totally under your control it's impossible to ensure
-key security so you may want to think carefully before using it for
-anything that requires high security, like storing credit card numbers.
-
-Your encryption key **must** be as long as the encyption algorithm in use
-allows. For AES-128, that's 128 bits or 16 bytes (charcters) long.
-You will find a table below that shows the supported key lengths of
-different ciphers.
-
-The key should be as random as possible and it **must not** be a regular
-text string, nor the output of a hashing function, etc. In order to create
-a proper key, you must use the Encryption library's ``create_key()`` method
-::
-
-	// $key will be assigned a 16-byte (128-bit) random key
-	$key = $this->encryption->create_key(16);
-
-The key can be either stored in your *application/config/config.php*, or
-you can design your own storage mechanism and pass the key dynamically
-when encrypting/decrypting.
-
-To save your key to your *application/config/config.php*, open the file
-and set::
-
-	$config['encryption_key'] = 'YOUR KEY';
-
-You'll notice that the ``create_key()`` method outputs binary data, which
-is hard to deal with (i.e. a copy-paste may damage it), so you may use
-``bin2hex()``, ``hex2bin()`` or Base64-encoding to work with the key in
-a more friendly manner. For example::
-
-	// Get a hex-encoded representation of the key:
-	$key = bin2hex($this->encryption->create_key(16));
-
-	// Put the same value in your config with hex2bin(),
-	// so that it is still passed as binary to the library:
-	$config['encryption_key'] = hex2bin(<your hex-encoded key>);
-
-.. _ciphers-and-modes:
-
-Supported encryption ciphers and modes
-======================================
-
-.. note:: The terms 'cipher' and 'encryption algorithm' are interchangeable.
-
-Portable ciphers
-----------------
-
-Because MCrypt and OpenSSL (also called drivers throughout this document)
-each support different sets of encryption algorithms and often implement
-them in different ways, our Encryption library is designed to use them in
-a portable fashion, or in other words - it enables you to use them
-interchangeably, at least for the ciphers supported by both drivers.
-
-It is also implemented in a way that aims to match the standard
-implementations in other programming languages and libraries.
-
-Here's a list of the so called "portable" ciphers, where
-"CodeIgniter name" is the string value that you'd have to pass to the
-Encryption library to use that cipher:
-
-======================== ================== ============================ ===============================
-Cipher name              CodeIgniter name   Key lengths (bits / bytes)   Supported modes
-======================== ================== ============================ ===============================
-AES-128 / Rijndael-128   aes-128            128 / 16                     CBC, CTR, CFB, CFB8, OFB, ECB
-AES-192                  aes-192            192 / 24                     CBC, CTR, CFB, CFB8, OFB, ECB
-AES-256                  aes-256            256 / 32                     CBC, CTR, CFB, CFB8, OFB, ECB
-DES                      des                56 / 7                       CBC, CFB, CFB8, OFB, ECB
-TripleDES                tripledes          56 / 7, 112 / 14, 168 / 21   CBC, CFB, CFB8, OFB
-Blowfish                 blowfish           128-448 / 16-56              CBC, CFB, OFB, ECB
-CAST5 / CAST-128         cast5              88-128 / 11-16               CBC, CFB, OFB, ECB
-RC4 / ARCFour            rc4                40-2048 / 5-256              Stream
-======================== ================== ============================ ===============================
-
-.. important:: Because of how MCrypt works, if you fail to provide a key
-	with the appropriate length, you might end up using a different
-	algorithm than the one configured, so be really careful with that!
-
-.. note:: In case it isn't clear from the above table, Blowfish, CAST5
-	and RC4 support variable length keys. That is, any number in the
-	shown ranges is valid, although in bit terms that only happens
-	in 8-bit increments.
-
-.. note:: Even though CAST5 supports key lengths lower than 128 bits
-	(16 bytes), in fact they will just be zero-padded to the
-	maximum length, as specified in `RFC 2144
-	<http://tools.ietf.org/rfc/rfc2144.txt>`_.
-
-.. note:: Blowfish supports key lengths as small as 32 bits (4 bytes), but
-	our tests have shown that only lengths of 128 bits (16 bytes) or
-	higher are properly supported by both MCrypt and OpenSSL. It is
-	also a bad practice to use such low-length keys anyway.
-
-Driver-specific ciphers
------------------------
-
-As noted above, MCrypt and OpenSSL support different sets of encryption
-ciphers. For portability reasons and because we haven't tested them
-properly, we do not advise you to use the ones that are driver-specific,
-but regardless, here's a list of most of them:

-============== ========= ============================== =========================================
-
-.. note:: If you wish to use one of those ciphers, you'd have to pass
-	its name in lower-case to the Encryption library.
-
-.. note:: You've probably noticed that all AES cipers (and Rijndael-128)
-	are also listed in the portable ciphers list. This is because
-	drivers support different modes for these ciphers. Also, it is
-	important to note that AES-128 and Rijndael-128 are actually
-	the same cipher, but **only** when used with a 128-bit key.
-
-.. note:: CAST-128 / CAST-5 is also listed in both the portable and
-	driver-specific ciphers list. This is because OpenSSL's
-	implementation doesn't appear to be working correctly with
-	key sizes of 80 bits and lower.
-
-.. note:: RC2 is listed as supported by both MCrypt and OpenSSL.
-	However, both drivers implement them differently and they
-	are not portable. It is probably worth noting that we only
-	found one obscure source confirming that it is MCrypt that
-	is not properly implementing it.
-
-.. _encryption-modes:
-
-Encryption modes
-----------------
-
-Different modes of encryption have different characteristics and serve
-for different purposes. Some are stronger than others, some are faster
-and some offer extra features.
-We are not going in depth into that here, we'll leave that to the
-cryptography experts. The table below is to provide brief informational
-reference to our more experienced users. If you are a beginner, just
-stick to the CBC mode - it is widely accepted as strong and secure for

-
-Message Length
-==============
-
-It's probably important for you to know that an encrypted string is usually
-longer than the original, plain-text string (depending on the cipher).
-
-This is influenced by the cipher algorithm itself, the IV prepended to the
-cipher-text and the HMAC authentication message that is also prepended.
-Furthermore, the encrypted message is also Base64-encoded so that it is safe
-for storage and transmission, regardless of a possible character set in use.
-
-Keep this information in mind when selecting your data storage mechanism.
-Cookies, for example, can only hold 4K of information.
-
-.. _configuration:
-
-Configuring the library
-=======================
-
-For usability, performance, but also historical reasons tied to our old
-:doc:`Encrypt Class <encrypt>`, the Encryption library is designed to
-use repeatedly the same driver, encryption cipher, mode and key.
-
-As noted in the "Default behavior" section above, this means using an
-auto-detected driver (OpenSSL has a higher priority), the AES-128 ciper
-in CBC mode, and your ``$config['encryption_key']`` value.
-
-If you wish to change that however, you need to use the ``initialize()``
-method. It accepts an associative array of parameters, all of which are
-optional:
-
-======== ===============================================
-Option   Possible values
-======== ===============================================
-driver   'mcrypt', 'openssl'
-cipher   Cipher name (see :ref:`ciphers-and-modes`)
-mode     Encryption mode (see :ref:`encryption-modes`)
-key      Encryption key 
-======== ===============================================
-
-For example, if you were to change the encryption algorithm and
-mode to AES-256 in CTR mode, this is what you should do::
-
-	$this->encryption->initialize(
-		array(
-			'cipher' => 'aes-256',
-			'mode' => 'ctr',
-			'key' => '<a 32-character random string>'
-		)
-	);
-
-Note that we only mentioned that you want to change the ciper and mode,
-but we also included a key in the example. As previously noted, it is
-important that you choose a key with a proper size for the used algorithm.
-
-There's also the ability to change the driver, if for some reason you
-have both, but want to use MCrypt instead of OpenSSL::
-
-	// Switch to the MCrypt driver
-	$this->encryption->initialize(array('driver' => 'mcrypt'));
-
-	// Switch back to the OpenSSL driver
-	$this->encryption->initialize(array('driver' => 'openssl'));
-
-Encrypting and decrypting data
-==============================
-
-Encrypting and decrypting data with the already configured library
-settings is simple. As simple as just passing the string to the
-``encrypt()`` and/or ``decrypt()`` methods::
-
-	$plain_text = 'This is a plain-text message!';
-	$ciphertext = $this->encryption->encrypt($plain_text);
-
-	// Outputs: This is a plain-text message!
-	echo $this->encryption->decrypt($ciphertext);
-
-And that's it! The Encryption library will do everything necessary
-for the whole process to be cryptographically secure out-of-the-box.
-You don't need to worry about it.
-
-.. important:: Both methods will return FALSE in case of an error.
-	While for ``encrypt()`` this can only mean incorrect
-	configuration, you should always check the return value
-	of ``decrypt()`` in production code.
-
-How it works
-------------
-
-If you must know how the process works, here's what happens under
-the hood:
-
-- ``$this->encryption->encrypt($plain_text)``
-
-  #. Derive an encryption key and a HMAC key from your configured
-     *encryption_key* via HKDF, using the SHA-512 digest algorithm.
-
-  #. Generate a random initialization vector (IV).
-
-  #. Encrypt the data via AES-128 in CBC mode (or another previously
-     configured cipher and mode), using the above-mentioned derived
-     encryption key and IV.
-
-  #. Prepend said IV to the resulting cipher-text.
-
-  #. Base64-encode the resulting string, so that it can be safely
-     stored or transferred without worrying about character sets.
-
-  #. Create a SHA-512 HMAC authentication message using the derived
-     HMAC key to ensure data integrity and prepend it to the Base64
-     string.
-
-- ``$this->encryption->decrypt($ciphertext)``
-
-  #. Derive an encryption key and a HMAC key from your configured
-     *encryption_key* via HKDF, using the SHA-512 digest algorithm.
-     Because your configured *encryption_key* is the same, this
-     will produce the same result as in the ``encrypt()`` method
-     above - otherwise you won't be able to decrypt it.
-
-  #. Check if the string is long enough, separate the HMAC out of
-     it and validate if it is correct (this is done in a way that
-     prevents timing attacks against it). Return FALSE if either of
-     the checks fails.
-
-  #. Base64-decode the string.
-
-  #. Separate the IV out of the cipher-text and decrypt the said
-     cipher-text using that IV and the derived encryption key.
-
-.. _custom-parameters:
-
-Using custom parameters
------------------------
-
-Let's say you have to interact with another system that is out
-of your control and uses another method to encrypt data. A
-method that will most certainly not match the above-described
-sequence and probably not use all of the steps either.
-
-The Encryption library allows you to change how its encryption
-and decryption processes work, so that you can easily tailor a
-custom solution for such situations.
-
-.. note:: It is possible to use the library in this way, without
-	setting an *encryption_key* in your configuration file.
-
-All you have to do is to pass an associative array with a few
-parameters to either the ``encrypt()`` or ``decrypt()`` method.
-Here's an example::
-
-	// Assume that we have $ciphertext, $key and $hmac_key
-	// from on outside source
-
-	$message = $this->encryption->decrypt(
-		$ciphertext,
-		array(
-			'cipher' => 'blowfish',
-			'mode' => 'cbc',
-			'key' => $key,
-			'hmac_digest' => 'sha256',
-			'hmac_key' => $hmac_key
-		)
-	);
-
-In the above example, we are decrypting a message that was encrypted
-using the Blowfish cipher in CBC mode and authenticated via a SHA-256
-HMAC.
-
-.. important:: Note that both 'key' and 'hmac_key' are used in this
-	example. When using custom parameters, encryption and HMAC keys
-	are not derived like the default behavior of the library is.
-
-Below is a list of the available options.
-
-However, unless you really need to and you know what you are doing,
-we advise you to not change the encryption process as this could
-impact security, so please do so with caution.
-
-============= =============== ============================= ======================================================
-Option        Default value   Mandatory / Optional          Description

-                                                            be a hexadecimal string.
-============= =============== ============================= ======================================================
-
-.. important:: ``encrypt()`` and ``decrypt()`` will return FALSE if
-	a mandatory parameter is not provided or if a provided
-	value is incorrect. This includes *hmac_key*, unless *hmac*
-	is set to FALSE.
-
-.. _digests:
-
-Supported HMAC authentication algorithms
-----------------------------------------
-
-For HMAC message authentication, the Encryption library supports
-usage of the SHA-2 family of algorithms:
-
-=========== ==================== ============================
-Algorithm   Raw length (bytes)   Hex-encoded length (bytes)
-=========== ==================== ============================
-sha512      64                   128
-sha384      48                   96
-sha256      32                   64
-sha224      28                   56
-=========== ==================== ============================
-
-The reason for not including other popular algorithms, such as
-MD5 or SHA1 is that they are no longer considered secure enough
-and as such, we don't want to encourage their usage.
-If you absolutely need to use them, it is easy to do so via PHP's
-native `hash_hmac() <http://php.net/manual/en/function.hash-hmac.php>`_ function.
-
-Stronger algorithms of course will be added in the future as they
-appear and become widely available.

-File Uploading Class
-####################
-
-CodeIgniter's File Uploading Class permits files to be uploaded. You can
-set various preferences, restricting the type and size of the files.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-***********
-The Process
-***********
-
-Uploading a file involves the following general process:
-
--  An upload form is displayed, allowing a user to select a file and
-   upload it.
--  When the form is submitted, the file is uploaded to the destination
-   you specify.
--  Along the way, the file is validated to make sure it is allowed to be
-   uploaded based on the preferences you set.
--  Once uploaded, the user will be shown a success message.
-
-To demonstrate this process here is brief tutorial. Afterward you'll
-find reference information.
-
-Creating the Upload Form
-========================
-
-Using a text editor, create a form called upload_form.php. In it, place
-this code and save it to your **application/views/** directory::
-
-	<html>
-	<head>
-	<title>Upload Form</title>
-	</head>
-	<body>
-
-	<?php echo $error;?>
-
-	<?php echo form_open_multipart('upload/do_upload');?>
-
-	<input type="file" name="userfile" size="20" />
-
-	<br /><br />
-
-	<input type="submit" value="upload" />
-
-	</form>
-
-	</body>
-	</html>
-
-You'll notice we are using a form helper to create the opening form tag.
-File uploads require a multipart form, so the helper creates the proper
-syntax for you. You'll also notice we have an $error variable. This is
-so we can show error messages in the event the user does something
-wrong.
-
-The Success Page
-================
-
-Using a text editor, create a form called upload_success.php. In it,
-place this code and save it to your **application/views/** directory::
-
-	<html>
-	<head>
-	<title>Upload Form</title>
-	</head>
-	<body>
-
-	<h3>Your file was successfully uploaded!</h3>
-
-	<ul>
-	<?php foreach ($upload_data as $item => $value):?>
-	<li><?php echo $item;?>: <?php echo $value;?></li>
-	<?php endforeach; ?>
-	</ul>
-
-	<p><?php echo anchor('upload', 'Upload Another File!'); ?></p>
-
-	</body>
-	</html>
-
-The Controller
-==============
-
-Using a text editor, create a controller called Upload.php. In it, place
-this code and save it to your **application/controllers/** directory::
-
-	<?php
-
-	class Upload extends CI_Controller {
-
-		public function __construct()
-		{
-			parent::__construct();
-			$this->load->helper(array('form', 'url'));
-		}
-
-		public function index()
-		{
-			$this->load->view('upload_form', array('error' => ' ' ));
-		}
-
-		public function do_upload()
-		{
-			$config['upload_path']		= './uploads/';
-			$config['allowed_types']	= 'gif|jpg|png';
-			$config['max_size']		= 100;
-			$config['max_width']		= 1024;
-			$config['max_height']		= 768;
-
-			$this->load->library('upload', $config);
-
-			if ( ! $this->upload->do_upload('userfile'))
-			{
-				$error = array('error' => $this->upload->display_errors());
-
-				$this->load->view('upload_form', $error);
-			}
-			else
-			{
-				$data = array('upload_data' => $this->upload->data());
-
-				$this->load->view('upload_success', $data);
-			}
-		}
-	}
-	?>
-
-The Upload Directory
-====================
-
-You'll need a destination directory for your uploaded images. Create a
-directory at the root of your CodeIgniter installation called uploads
-and set its file permissions to 777.
-
-Try it!
-=======
-
-To try your form, visit your site using a URL similar to this one::
-
-	example.com/index.php/upload/
-
-You should see an upload form. Try uploading an image file (either a
-jpg, gif, or png). If the path in your controller is correct it should
-work.
-
-***************
-Reference Guide
-***************
-
-Initializing the Upload Class
-=============================
-
-Like most other classes in CodeIgniter, the Upload class is initialized
-in your controller using the ``$this->load->library()`` method::
-
-	$this->load->library('upload');
-
-Once the Upload class is loaded, the object will be available using:
-$this->upload
-
-Setting Preferences
-===================
-
-Similar to other libraries, you'll control what is allowed to be upload
-based on your preferences. In the controller you built above you set the
-following preferences::
-
-	$config['upload_path'] = './uploads/';
-	$config['allowed_types'] = 'gif|jpg|png';
-	$config['max_size']	= '100';
-	$config['max_width'] = '1024';
-	$config['max_height'] = '768';
-
-	$this->load->library('upload', $config);
-
-	// Alternately you can set preferences by calling the ``initialize()`` method. Useful if you auto-load the class:
-	$this->upload->initialize($config);
-
-The above preferences should be fairly self-explanatory. Below is a
-table describing all available preferences.
-
-Preferences
-===========
-
-The following preferences are available. The default value indicates
-what will be used if you do not specify that preference.

-**min_width**                0                 None                    The minimum width (in pixels) that the image can be. Set to zero for no

-**min_height**               0                 None                    The minimum height (in pixels) that the image can be. Set to zero for no
-                                                                       limit.
-**max_filename**             0                 None                    The maximum length that a file name can be. Set to zero for no limit.
-**max_filename_increment**   100               None                    When overwrite is set to FALSE, use this to set the maximum filename

-**encrypt_name**             FALSE             TRUE/FALSE (boolean)    If set to TRUE the file name will be converted to a random encrypted

-                                                                       that can not be discerned by the person uploading it.

-Setting preferences in a config file
-====================================
-
-If you prefer not to set preferences using the above method, you can
-instead put them into a config file. Simply create a new file called the
-upload.php, add the $config array in that file. Then save the file in:
-**config/upload.php** and it will be used automatically. You will NOT
-need to use the ``$this->upload->initialize()`` method if you save your
-preferences in a config file.
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_Upload
-
-	.. php:method:: initialize([array $config = array()[, $reset = TRUE]])
-
-		:param	array	$config: Preferences
-		:param	bool	$reset: Whether to reset preferences (that are not provided in $config) to their defaults
-		:returns:	CI_Upload instance (method chaining)
-		:rtype:	CI_Upload
-
-	.. php:method:: do_upload([$field = 'userfile'])
-
-		:param	string	$field: Name of the form field
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		Performs the upload based on the preferences you've set.
-
-		.. note:: By default the upload routine expects the file to come from
-			a form field called userfile, and the form must be of type
-			"multipart".
-
-		::
-
-			<form method="post" action="some_action" enctype="multipart/form-data" />
-
-		If you would like to set your own field name simply pass its value to
-		the ``do_upload()`` method::
-
-			$field_name = "some_field_name";
-			$this->upload->do_upload($field_name);
-
-	.. php:method:: display_errors([$open = '<p>'[, $close = '</p>']])
-
-		:param	string	$open: Opening markup
-		:param	string	$close: Closing markup
-		:returns:	Formatted error message(s)
-		:rtype:	string
-
-		Retrieves any error messages if the ``do_upload()`` method returned
-		false. The method does not echo automatically, it returns the data so
-		you can assign it however you need.
-
-		**Formatting Errors**
-
-			By default the above method wraps any errors within <p> tags. You can
-			set your own delimiters like this::
-
-				$this->upload->display_errors('<p>', '</p>');
-
-
-	.. php:method:: data([$index = NULL])
-
-		:param	string	$data: Element to return instead of the full array
-		:returns:	Information about the uploaded file
-		:rtype:	mixed
-
-		This is a helper method that returns an array containing all of the
-		data related to the file you uploaded. Here is the array prototype::
-
-			Array
-			(
-				[file_name]	=> mypic.jpg
-				[file_type]	=> image/jpeg
-				[file_path]	=> /path/to/your/upload/
-				[full_path]	=> /path/to/your/upload/jpg.jpg
-				[raw_name]	=> mypic
-				[orig_name]	=> mypic.jpg
-				[client_name]	=> mypic.jpg
-				[file_ext]	=> .jpg
-				[file_size]	=> 22.2
-				[is_image]	=> 1
-				[image_width]	=> 800
-				[image_height]	=> 600
-				[image_type]	=> jpeg
-				[image_size_str] => width="800" height="200"
-			)
-
-		To return one element from the array::
-
-			$this->upload->data('file_name');	// Returns: mypic.jpg
-
-		Here's a table explaining the above-displayed array items:
-
-		================ ====================================================================================================
-		Item             Description
-		================ ====================================================================================================
-		file_name        Name of the file that was uploaded, including the filename extension
-		file_type        File MIME type identifier
-		file_path        Absolute server path to the file
-		full_path        Absolute server path, including the file name
-		raw_name         File name, without the extension
-		orig_name        Original file name. This is only useful if you use the encrypted name option.
-		client_name      File name as supplied by the client user agent, prior to any file name preparation or incrementing
-		file_ext         Filename extension, period included
-		file_size        File size in kilobytes
-		is_image         Whether the file is an image or not. 1 = image. 0 = not.
-		image_width      Image width
-		image_height     Image height
-		image_type       Image type (usually the file name extension without the period)
-		image_size_str   A string containing the width and height (useful to put into an image tag)

-Form Validation
-###############
-
-CodeIgniter provides a comprehensive form validation and data prepping
-class that helps minimize the amount of code you'll write.
-
-.. contents:: Page Contents
-
-********
-Overview
-********
-
-Before explaining CodeIgniter's approach to data validation, let's
-describe the ideal scenario:
-
-#. A form is displayed.
-#. You fill it in and submit it.
-#. If you submitted something invalid, or perhaps missed a required
-   item, the form is redisplayed containing your data along with an
-   error message describing the problem.
-#. This process continues until you have submitted a valid form.
-
-On the receiving end, the script must:
-
-#. Check for required data.
-#. Verify that the data is of the correct type, and meets the correct
-   criteria. For example, if a username is submitted it must be
-   validated to contain only permitted characters. It must be of a
-   minimum length, and not exceed a maximum length. The username can't
-   be someone else's existing username, or perhaps even a reserved word.
-   Etc.
-#. Sanitize the data for security.
-#. Pre-format the data if needed (Does the data need to be trimmed? HTML
-   encoded? Etc.)
-#. Prep the data for insertion in the database.
-
-Although there is nothing terribly complex about the above process, it
-usually requires a significant amount of code, and to display error
-messages, various control structures are usually placed within the form
-HTML. Form validation, while simple to create, is generally very messy
-and tedious to implement.
-
-************************
-Form Validation Tutorial
-************************
-
-What follows is a "hands on" tutorial for implementing CodeIgniters Form
-Validation.
-
-In order to implement form validation you'll need three things:
-
-#. A :doc:`View <../general/views>` file containing a form.
-#. A View file containing a "success" message to be displayed upon
-   successful submission.
-#. A :doc:`controller <../general/controllers>` method to receive and
-   process the submitted data.
-
-Let's create those three things, using a member sign-up form as the
-example.
-
-The Form
-========
-
-Using a text editor, create a form called myform.php. In it, place this
-code and save it to your application/views/ folder::
-
-	<html>
-	<head>
-	<title>My Form</title>
-	</head>
-	<body>
-
-	<?php echo validation_errors(); ?>
-
-	<?php echo form_open('form'); ?>
-
-	<h5>Username</h5>
-	<input type="text" name="username" value="" size="50" />
-
-	<h5>Password</h5>
-	<input type="text" name="password" value="" size="50" />
-
-	<h5>Password Confirm</h5>
-	<input type="text" name="passconf" value="" size="50" />
-
-	<h5>Email Address</h5>
-	<input type="text" name="email" value="" size="50" />
-
-	<div><input type="submit" value="Submit" /></div>
-
-	</form>
-
-	</body>
-	</html>
-
-The Success Page
-================
-
-Using a text editor, create a form called formsuccess.php. In it, place
-this code and save it to your application/views/ folder::
-
-	<html>
-	<head>
-	<title>My Form</title>
-	</head>
-	<body>
-
-	<h3>Your form was successfully submitted!</h3>
-
-	<p><?php echo anchor('form', 'Try it again!'); ?></p>
-
-	</body>
-	</html>
-
-The Controller
-==============
-
-Using a text editor, create a controller called Form.php. In it, place
-this code and save it to your application/controllers/ folder::
-
-	<?php
-
-	class Form extends CI_Controller {
-
-		public function index()
-		{
-			$this->load->helper(array('form', 'url'));
-
-			$this->load->library('form_validation');
-
-			if ($this->form_validation->run() == FALSE)
-			{
-				$this->load->view('myform');
-			}
-			else
-			{
-				$this->load->view('formsuccess');
-			}
-		}
-	}
-
-Try it!
-=======
-
-To try your form, visit your site using a URL similar to this one::
-
-	example.com/index.php/form/
-
-If you submit the form you should simply see the form reload. That's
-because you haven't set up any validation rules yet.
-
-**Since you haven't told the Form Validation class to validate anything
-yet, it returns FALSE (boolean false) by default. ``The run()`` method
-only returns TRUE if it has successfully applied your rules without any
-of them failing.**
-
-Explanation
-===========
-
-You'll notice several things about the above pages:
-
-The form (myform.php) is a standard web form with a couple exceptions:
-
-#. It uses a form helper to create the form opening. Technically, this
-   isn't necessary. You could create the form using standard HTML.
-   However, the benefit of using the helper is that it generates the
-   action URL for you, based on the URL in your config file. This makes
-   your application more portable in the event your URLs change.
-#. At the top of the form you'll notice the following function call:
-   ::
-
-	<?php echo validation_errors(); ?>
-
-   This function will return any error messages sent back by the
-   validator. If there are no messages it returns an empty string.
-
-The controller (Form.php) has one method: ``index()``. This method
-initializes the validation class and loads the form helper and URL
-helper used by your view files. It also runs the validation routine.
-Based on whether the validation was successful it either presents the
-form or the success page.
-
-.. _setting-validation-rules:
-
-Setting Validation Rules
-========================
-
-CodeIgniter lets you set as many validation rules as you need for a
-given field, cascading them in order, and it even lets you prep and
-pre-process the field data at the same time. To set validation rules you
-will use the ``set_rules()`` method::
-
-	$this->form_validation->set_rules();
-
-The above method takes **three** parameters as input:
-
-#. The field name - the exact name you've given the form field.
-#. A "human" name for this field, which will be inserted into the error
-   message. For example, if your field is named "user" you might give it
-   a human name of "Username".
-#. The validation rules for this form field.
-#. (optional) Set custom error messages on any rules given for current field. If not provided will use the default one.
-
-.. note:: If you would like the field name to be stored in a language
-	file, please see :ref:`translating-field-names`.
-
-Here is an example. In your controller (Form.php), add this code just
-below the validation initialization method::
-
-	$this->form_validation->set_rules('username', 'Username', 'required');
-	$this->form_validation->set_rules('password', 'Password', 'required');
-	$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
-	$this->form_validation->set_rules('email', 'Email', 'required');
-
-Your controller should now look like this::
-
-	<?php
-
-	class Form extends CI_Controller {
-
-		public function index()
-		{
-			$this->load->helper(array('form', 'url'));
-
-			$this->load->library('form_validation');
-
-			$this->form_validation->set_rules('username', 'Username', 'required');
-			$this->form_validation->set_rules('password', 'Password', 'required',
-				array('required' => 'You must provide a %s.')
-			);
-			$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
-			$this->form_validation->set_rules('email', 'Email', 'required');
-
-			if ($this->form_validation->run() == FALSE)
-			{
-				$this->load->view('myform');
-			}
-			else
-			{
-				$this->load->view('formsuccess');
-			}
-		}
-	}
-
-Now submit the form with the fields blank and you should see the error
-messages. If you submit the form with all the fields populated you'll
-see your success page.
-
-.. note:: The form fields are not yet being re-populated with the data
-	when there is an error. We'll get to that shortly.
-
-Setting Rules Using an Array
-============================
-
-Before moving on it should be noted that the rule setting method can
-be passed an array if you prefer to set all your rules in one action. If
-you use this approach, you must name your array keys as indicated::
-
-	$config = array(
-		array(
-			'field' => 'username',
-			'label' => 'Username',
-			'rules' => 'required'
-		),
-		array(
-			'field' => 'password',
-			'label' => 'Password',
-			'rules' => 'required',
-			'errors' => array(
-				'required' => 'You must provide a %s.',
-			),
-		),
-		array(
-			'field' => 'passconf',
-			'label' => 'Password Confirmation',
-			'rules' => 'required'
-		),
-		array(
-			'field' => 'email',
-			'label' => 'Email',
-			'rules' => 'required'
-		)
-	);
-
-	$this->form_validation->set_rules($config);
-
-Cascading Rules
-===============
-
-CodeIgniter lets you pipe multiple rules together. Let's try it. Change
-your rules in the third parameter of rule setting method, like this::
-
-	$this->form_validation->set_rules(
-		'username', 'Username',
-		'required|min_length[5]|max_length[12]|is_unique[users.username]',
-		array(
-			'required'	=> 'You have not provided %s.',
-			'is_unique'	=> 'This %s already exists.'
-		)
-	);
-	$this->form_validation->set_rules('password', 'Password', 'required');
-	$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required|matches[password]');
-	$this->form_validation->set_rules('email', 'Email', 'required|valid_email|is_unique[users.email]');
-
-The above code sets the following rules:
-
-#. The username field be no shorter than 5 characters and no longer than
-   12.
-#. The password field must match the password confirmation field.
-#. The email field must contain a valid email address.
-
-Give it a try! Submit your form without the proper data and you'll see
-new error messages that correspond to your new rules. There are numerous
-rules available which you can read about in the validation reference.
-
-.. note:: You can also pass an array of rules to ``set_rules()``,
-	instead of a string. Example::
-
-	$this->form_validation->set_rules('username', 'Username', array('required', 'min_length[5]'));
-
-Prepping Data
-=============
-
-In addition to the validation method like the ones we used above, you
-can also prep your data in various ways. For example, you can set up
-rules like this::
-
-	$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[5]|max_length[12]');
-	$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[8]');
-	$this->form_validation->set_rules('passconf', 'Password Confirmation', 'trim|required|matches[password]');
-	$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');
-
-In the above example, we are "trimming" the fields, checking for length
-where necessary and making sure that both password fields match.
-
-**Any native PHP function that accepts one parameter can be used as a
-rule, like ``htmlspecialchars()``, ``trim()``, etc.**
-
-.. note:: You will generally want to use the prepping functions
-	**after** the validation rules so if there is an error, the
-	original data will be shown in the form.
-
-Re-populating the form
-======================
-
-Thus far we have only been dealing with errors. It's time to repopulate
-the form field with the submitted data. CodeIgniter offers several
-helper functions that permit you to do this. The one you will use most
-commonly is::
-
-	set_value('field name')
-
-Open your myform.php view file and update the **value** in each field
-using the :php:func:`set_value()` function:
-
-**Don't forget to include each field name in the :php:func:`set_value()`
-function calls!**
-
-::
-
-	<html>
-	<head>
-	<title>My Form</title>
-	</head>
-	<body>
-
-	<?php echo validation_errors(); ?>
-
-	<?php echo form_open('form'); ?>
-
-	<h5>Username</h5>
-	<input type="text" name="username" value="<?php echo set_value('username'); ?>" size="50" />
-
-	<h5>Password</h5>
-	<input type="text" name="password" value="<?php echo set_value('password'); ?>" size="50" />
-
-	<h5>Password Confirm</h5>
-	<input type="text" name="passconf" value="<?php echo set_value('passconf'); ?>" size="50" />
-
-	<h5>Email Address</h5>
-	<input type="text" name="email" value="<?php echo set_value('email'); ?>" size="50" />
-
-	<div><input type="submit" value="Submit" /></div>
-
-	</form>
-
-	</body>
-	</html>
-
-Now reload your page and submit the form so that it triggers an error.
-Your form fields should now be re-populated
-
-.. note:: The :ref:`class-reference` section below
-	contains methods that permit you to re-populate <select> menus,
-	radio buttons, and checkboxes.
-
-.. important:: If you use an array as the name of a form field, you
-	must supply it as an array to the function. Example::
-
-	<input type="text" name="colors[]" value="<?php echo set_value('colors[]'); ?>" size="50" />
-
-For more info please see the :ref:`using-arrays-as-field-names` section below.
-
-Callbacks: Your own Validation Methods
-======================================
-
-The validation system supports callbacks to your own validation
-methods. This permits you to extend the validation class to meet your
-needs. For example, if you need to run a database query to see if the
-user is choosing a unique username, you can create a callback method
-that does that. Let's create an example of this.
-
-In your controller, change the "username" rule to this::
-
-	$this->form_validation->set_rules('username', 'Username', 'callback_username_check');
-
-Then add a new method called ``username_check()`` to your controller.
-Here's how your controller should now look::
-
-	<?php
-
-	class Form extends CI_Controller {
-
-		public function index()
-		{
-			$this->load->helper(array('form', 'url'));
-
-			$this->load->library('form_validation');
-
-			$this->form_validation->set_rules('username', 'Username', 'callback_username_check');
-			$this->form_validation->set_rules('password', 'Password', 'required');
-			$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
-			$this->form_validation->set_rules('email', 'Email', 'required|is_unique[users.email]');
-
-			if ($this->form_validation->run() == FALSE)
-			{
-				$this->load->view('myform');
-			}
-			else
-			{
-				$this->load->view('formsuccess');
-			}
-		}
-
-		public function username_check($str)
-		{
-			if ($str == 'test')
-			{
-				$this->form_validation->set_message('username_check', 'The {field} field can not be the word "test"');
-				return FALSE;
-			}
-			else
-			{
-				return TRUE;
-			}
-		}
-
-	}
-
-Reload your form and submit it with the word "test" as the username. You
-can see that the form field data was passed to your callback method
-for you to process.
-
-To invoke a callback just put the method name in a rule, with
-"callback\_" as the rule **prefix**. If you need to receive an extra
-parameter in your callback method, just add it normally after the
-method name between square brackets, as in: ``callback_foo[bar]``,
-then it will be passed as the second argument of your callback method.
-
-.. note:: You can also process the form data that is passed to your
-	callback and return it. If your callback returns anything other than a
-	boolean TRUE/FALSE it is assumed that the data is your newly processed
-	form data.
-
-Callable: Use anything as a rule
-================================
-
-If callback rules aren't good enough for you (for example, because they are
-limited to your controller), don't get disappointed, there's one more way
-to create custom rules: anything that ``is_callable()`` would return TRUE for.
-
-Consider the following example::
-
-	$this->form_validation->set_rules(
-		'username', 'Username',
-		array(
-			'required',
-			array($this->users_model, 'valid_username')
-		)
-	);
-
-The above code would use the ``valid_username()`` method from your
-``Users_model`` object.
-
-This is just an example of course, and callbacks aren't limited to models.
-You can use any object/method that accepts the field value as its' first
-parameter. You can also use an anonymous function::
-
-	$this->form_validation->set_rules(
-		'username', 'Username',
-		array(
-			'required',
-			function($value)
-			{
-				// Check $value
-			}
-		)
-	);
-
-Of course, since a Callable rule by itself is not a string, it isn't
-a rule name either. That is a problem when you want to set error messages
-for them. In order to get around that problem, you can put such rules as
-the second element of an array, with the first one being the rule name::
-
-	$this->form_validation->set_rules(
-		'username', 'Username',
-		array(
-			'required',
-			array('username_callable', array($this->users_model, 'valid_username'))
-		)
-	);
-
-Anonymous function version::
-
-	$this->form_validation->set_rules(
-		'username', 'Username',
-		array(
-			'required',
-			array(
-				'username_callable',
-				function($str)
-				{
-					// Check validity of $str and return TRUE or FALSE
-				}
-			)
-		)
-	);
-
-.. _setting-error-messages:
-
-Setting Error Messages
-======================
-
-All of the native error messages are located in the following language
-file: **system/language/english/form_validation_lang.php**
-
-To set your own global custom message for a rule, you can either 
-extend/override the language file by creating your own in
-**application/language/english/form_validation_lang.php** (read more
-about this in the :doc:`Language Class <language>` documentation),
-or use the following method::
-
-	$this->form_validation->set_message('rule', 'Error Message');
-
-If you need to set a custom error message for a particular field on 
-some particular rule, use the set_rules() method::
-
-	$this->form_validation->set_rules('field_name', 'Field Label', 'rule1|rule2|rule3',
-		array('rule2' => 'Error Message on rule2 for this field_name')
-	);
-
-Where rule corresponds to the name of a particular rule, and Error
-Message is the text you would like displayed.
-
-If you'd like to include a field's "human" name, or the optional
-parameter some rules allow for (such as max_length), you can add the
-**{field}** and **{param}** tags to your message, respectively::
-
-	$this->form_validation->set_message('min_length', '{field} must have at least {param} characters.');
-
-On a field with the human name Username and a rule of min_length[5], an
-error would display: "Username must have at least 5 characters."
-
-.. note:: The old `sprintf()` method of using **%s** in your error messages
-	will still work, however it will override the tags above. You should
-	use one or the other.
-
-In the callback rule example above, the error message was set by passing
-the name of the method (without the "callback\_" prefix)::
-
-	$this->form_validation->set_message('username_check')
-
-.. _translating-field-names:
-
-Translating Field Names
-=======================
-
-If you would like to store the "human" name you passed to the
-``set_rules()`` method in a language file, and therefore make the name
-able to be translated, here's how:
-
-First, prefix your "human" name with **lang:**, as in this example::
-
-	 $this->form_validation->set_rules('first_name', 'lang:first_name', 'required');
-
-Then, store the name in one of your language file arrays (without the
-prefix)::
-
-	$lang['first_name'] = 'First Name';
-
-.. note:: If you store your array item in a language file that is not
-	loaded automatically by CI, you'll need to remember to load it in your
-	controller using::
-
-	$this->lang->load('file_name');
-
-See the :doc:`Language Class <language>` page for more info regarding
-language files.
-
-.. _changing-delimiters:
-
-Changing the Error Delimiters
-=============================
-
-By default, the Form Validation class adds a paragraph tag (<p>) around
-each error message shown. You can either change these delimiters
-globally, individually, or change the defaults in a config file.
-
-#. **Changing delimiters Globally**
-   To globally change the error delimiters, in your controller method,
-   just after loading the Form Validation class, add this::
-
-      $this->form_validation->set_error_delimiters('<div class="error">', '</div>');
-
-   In this example, we've switched to using div tags.
-
-#. **Changing delimiters Individually**
-   Each of the two error generating functions shown in this tutorial can
-   be supplied their own delimiters as follows::
-
-      <?php echo form_error('field name', '<div class="error">', '</div>'); ?>
-
-   Or::
-
-      <?php echo validation_errors('<div class="error">', '</div>'); ?>
-
-#. **Set delimiters in a config file**
-   You can add your error delimiters in application/config/form_validation.php as follows::
-
-      $config['error_prefix'] = '<div class="error_prefix">';
-      $config['error_suffix'] = '</div>';
-
-Showing Errors Individually
-===========================
-
-If you prefer to show an error message next to each form field, rather
-than as a list, you can use the :php:func:`form_error()` function.
-
-Try it! Change your form so that it looks like this::
-
-	<h5>Username</h5>
-	<?php echo form_error('username'); ?>
-	<input type="text" name="username" value="<?php echo set_value('username'); ?>" size="50" />
-
-	<h5>Password</h5>
-	<?php echo form_error('password'); ?>
-	<input type="text" name="password" value="<?php echo set_value('password'); ?>" size="50" />
-
-	<h5>Password Confirm</h5>
-	<?php echo form_error('passconf'); ?>
-	<input type="text" name="passconf" value="<?php echo set_value('passconf'); ?>" size="50" />
-
-	<h5>Email Address</h5>
-	<?php echo form_error('email'); ?>
-	<input type="text" name="email" value="<?php echo set_value('email'); ?>" size="50" />
-
-If there are no errors, nothing will be shown. If there is an error, the
-message will appear.
-
-.. important:: If you use an array as the name of a form field, you
-	must supply it as an array to the function. Example::
-
-	<?php echo form_error('options[size]'); ?>
-	<input type="text" name="options[size]" value="<?php echo set_value("options[size]"); ?>" size="50" />
-
-For more info please see the :ref:`using-arrays-as-field-names` section below.
-
-Validating an Array (other than $_POST)
-=======================================
-
-Sometimes you may want to validate an array that does not originate from ``$_POST`` data.
-
-In this case, you can specify the array to be validated::
-
-	$data = array(
-		'username' => 'johndoe',
-		'password' => 'mypassword',
-		'passconf' => 'mypassword'
-	);
-
-	$this->form_validation->set_data($data);
-
-Creating validation rules, running the validation, and retrieving error
-messages works the same whether you are validating ``$_POST`` data or
-another array of your choice.
-
-.. important:: You have to call the ``set_data()`` method *before* defining
-	any validation rules.
-
-.. important:: If you want to validate more than one array during a single
-	execution, then you should call the ``reset_validation()`` method
-	before setting up rules and validating the new array.
-
-For more info please see the :ref:`class-reference` section below.
-
-.. _saving-groups:
-
-************************************************
-Saving Sets of Validation Rules to a Config File
-************************************************
-
-A nice feature of the Form Validation class is that it permits you to
-store all your validation rules for your entire application in a config
-file. You can organize these rules into "groups". These groups can
-either be loaded automatically when a matching controller/method is
-called, or you can manually call each set as needed.
-
-How to save your rules
-======================
-
-To store your validation rules, simply create a file named
-form_validation.php in your application/config/ folder. In that file
-you will place an array named $config with your rules. As shown earlier,
-the validation array will have this prototype::
-
-	$config = array(
-		array(
-			'field' => 'username',
-			'label' => 'Username',
-			'rules' => 'required'
-		),
-		array(
-			'field' => 'password',
-			'label' => 'Password',
-			'rules' => 'required'
-		),
-		array(
-			'field' => 'passconf',
-			'label' => 'Password Confirmation',
-			'rules' => 'required'
-		),
-		array(
-			'field' => 'email',
-			'label' => 'Email',
-			'rules' => 'required'
-		)
-	);
-
-Your validation rule file will be loaded automatically and used when you
-call the ``run()`` method.
-
-Please note that you MUST name your ``$config`` array.
-
-Creating Sets of Rules
-======================
-
-In order to organize your rules into "sets" requires that you place them
-into "sub arrays". Consider the following example, showing two sets of
-rules. We've arbitrarily called these two rules "signup" and "email".
-You can name your rules anything you want::
-
-	$config = array(
-		'signup' => array(
-			array(
-				'field' => 'username',
-				'label' => 'Username',
-				'rules' => 'required'
-			),
-			array(
-				'field' => 'password',
-				'label' => 'Password',
-				'rules' => 'required'
-			),
-			array(
-				'field' => 'passconf',
-				'label' => 'Password Confirmation',
-				'rules' => 'required'
-			),
-			array(
-				'field' => 'email',
-				'label' => 'Email',
-				'rules' => 'required'
-			)
-		),
-		'email' => array(
-			array(
-				'field' => 'emailaddress',
-				'label' => 'EmailAddress',
-				'rules' => 'required|valid_email'
-			),
-			array(
-				'field' => 'name',
-				'label' => 'Name',
-				'rules' => 'required|alpha'
-			),
-			array(
-				'field' => 'title',
-				'label' => 'Title',
-				'rules' => 'required'
-			),
-			array(
-				'field' => 'message',
-				'label' => 'MessageBody',
-				'rules' => 'required'
-			)
-		)
-	);
-
-Calling a Specific Rule Group
-=============================
-
-In order to call a specific group, you will pass its name to the ``run()``
-method. For example, to call the signup rule you will do this::
-
-	if ($this->form_validation->run('signup') == FALSE)
-	{
-		$this->load->view('myform');
-	}
-	else
-	{
-		$this->load->view('formsuccess');
-	}
-
-Associating a Controller Method with a Rule Group
-=================================================
-
-An alternate (and more automatic) method of calling a rule group is to
-name it according to the controller class/method you intend to use it
-with. For example, let's say you have a controller named Member and a
-method named signup. Here's what your class might look like::
-
-	<?php
-
-	class Member extends CI_Controller {
-
-		public function signup()
-		{
-			$this->load->library('form_validation');
-
-			if ($this->form_validation->run() == FALSE)
-			{
-				$this->load->view('myform');
-			}
-			else
-			{
-				$this->load->view('formsuccess');
-			}
-		}
-	}
-
-In your validation config file, you will name your rule group
-member/signup::
-
-	$config = array(
-		'member/signup' => array(
-			array(
-				'field' => 'username',
-				'label' => 'Username',
-				'rules' => 'required'
-			),
-			array(
-				'field' => 'password',
-				'label' => 'Password',
-				'rules' => 'required'
-			),
-			array(
-				'field' => 'passconf',
-				'label' => 'PasswordConfirmation',
-				'rules' => 'required'
-			),
-			array(
-				'field' => 'email',
-				'label' => 'Email',
-				'rules' => 'required'
-			)
-		)
-	);
-
-When a rule group is named identically to a controller class/method it
-will be used automatically when the ``run()`` method is invoked from that
-class/method.
-
-.. _using-arrays-as-field-names:
-
-***************************
-Using Arrays as Field Names
-***************************
-
-The Form Validation class supports the use of arrays as field names.
-Consider this example::
-
-	<input type="text" name="options[]" value="" size="50" />
-
-If you do use an array as a field name, you must use the EXACT array
-name in the :ref:`Helper Functions <helper-functions>` that require the
-field name, and as your Validation Rule field name.
-
-For example, to set a rule for the above field you would use::
-
-	$this->form_validation->set_rules('options[]', 'Options', 'required');
-
-Or, to show an error for the above field you would use::
-
-	<?php echo form_error('options[]'); ?>
-
-Or to re-populate the field you would use::
-
-	<input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>" size="50" />
-
-You can use multidimensional arrays as field names as well. For example::
-
-	<input type="text" name="options[size]" value="" size="50" />
-
-Or even::
-
-	<input type="text" name="sports[nba][basketball]" value="" size="50" />
-
-As with our first example, you must use the exact array name in the
-helper functions::
-
-	<?php echo form_error('sports[nba][basketball]'); ?>
-
-If you are using checkboxes (or other fields) that have multiple
-options, don't forget to leave an empty bracket after each option, so
-that all selections will be added to the POST array::
-
-	<input type="checkbox" name="options[]" value="red" />
-	<input type="checkbox" name="options[]" value="blue" />
-	<input type="checkbox" name="options[]" value="green" />
-
-Or if you use a multidimensional array::
-
-	<input type="checkbox" name="options[color][]" value="red" />
-	<input type="checkbox" name="options[color][]" value="blue" />
-	<input type="checkbox" name="options[color][]" value="green" />
-
-When you use a helper function you'll include the bracket as well::
-
-	<?php echo form_error('options[color][]'); ?>

-FTP Class
-#########
-
-CodeIgniter's FTP Class permits files to be transferred to a remote
-server. Remote files can also be moved, renamed, and deleted. The FTP
-class also includes a "mirroring" function that permits an entire local
-directory to be recreated remotely via FTP.
-
-.. note:: SFTP and SSL FTP protocols are not supported, only standard
-	FTP.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-**************************
-Working with the FTP Class
-**************************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the FTP class is initialized in
-your controller using the $this->load->library function::
-
-	$this->load->library('ftp');
-
-Once loaded, the FTP object will be available using: $this->ftp
-
-Usage Examples
-==============
-
-In this example a connection is opened to the FTP server, and a local
-file is read and uploaded in ASCII mode. The file permissions are set to
-755.
-::
-
-	$this->load->library('ftp');
-
-	$config['hostname'] = 'ftp.example.com';
-	$config['username'] = 'your-username';
-	$config['password'] = 'your-password';
-	$config['debug']	= TRUE;
-
-	$this->ftp->connect($config);
-
-	$this->ftp->upload('/local/path/to/myfile.html', '/public_html/myfile.html', 'ascii', 0775);
-
-	$this->ftp->close();
-
-In this example a list of files is retrieved from the server.
-::
-
-	$this->load->library('ftp');
-
-	$config['hostname'] = 'ftp.example.com';
-	$config['username'] = 'your-username';
-	$config['password'] = 'your-password';
-	$config['debug']	= TRUE;
-
-	$this->ftp->connect($config);
-
-	$list = $this->ftp->list_files('/public_html/');
-
-	print_r($list);
-
-	$this->ftp->close();
-
-In this example a local directory is mirrored on the server.
-::
-
-	$this->load->library('ftp');
-
-	$config['hostname'] = 'ftp.example.com';
-	$config['username'] = 'your-username';
-	$config['password'] = 'your-password';
-	$config['debug']	= TRUE;
-
-	$this->ftp->connect($config);
-
-	$this->ftp->mirror('/path/to/myfolder/', '/public_html/myfolder/');
-
-	$this->ftp->close();
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_FTP
-
-	.. php:method:: connect([$config = array()])
-
-		:param	array	$config: Connection values
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		Connects and logs into to the FTP server. Connection preferences are set
-		by passing an array to the function, or you can store them in a config
-		file.
-
-		Here is an example showing how you set preferences manually::
-
-			$this->load->library('ftp');
-
-			$config['hostname'] = 'ftp.example.com';
-			$config['username'] = 'your-username';
-			$config['password'] = 'your-password';
-			$config['port']     = 21;
-			$config['passive']  = FALSE;
-			$config['debug']    = TRUE;
-
-			$this->ftp->connect($config);
-
-		**Setting FTP Preferences in a Config File**
-
-		If you prefer you can store your FTP preferences in a config file.
-		Simply create a new file called the ftp.php, add the $config array in
-		that file. Then save the file at *application/config/ftp.php* and it
-		will be used automatically.

-Image Manipulation Class
-########################
-
-CodeIgniter's Image Manipulation class lets you perform the following
-actions:
-
--  Image Resizing
--  Thumbnail Creation
--  Image Cropping
--  Image Rotating
--  Image Watermarking
-
-All three major image libraries are supported: GD/GD2, NetPBM, and
-ImageMagick
-
-.. note:: Watermarking is only available using the GD/GD2 library. In
-	addition, even though other libraries are supported, GD is required in
-	order for the script to calculate the image properties. The image
-	processing, however, will be performed with the library you specify.
-
-.. contents::
-  :local:

-
-**********************
-Initializing the Class
-**********************
-
-Like most other classes in CodeIgniter, the image class is initialized
-in your controller using the $this->load->library function::
-
-	$this->load->library('image_lib');
-
-Once the library is loaded it will be ready for use. The image library
-object you will use to call all functions is: ``$this->image_lib``
-
-Processing an Image
-===================
-
-Regardless of the type of processing you would like to perform
-(resizing, cropping, rotation, or watermarking), the general process is
-identical. You will set some preferences corresponding to the action you
-intend to perform, then call one of four available processing functions.
-For example, to create an image thumbnail you'll do this::
-
-	$config['image_library'] = 'gd2';
-	$config['source_image']	= '/path/to/image/mypic.jpg';
-	$config['create_thumb'] = TRUE;
-	$config['maintain_ratio'] = TRUE;
-	$config['width']	 = 75;
-	$config['height']	= 50;
-
-	$this->load->library('image_lib', $config); 
-
-	$this->image_lib->resize();
-
-The above code tells the image_resize function to look for an image
-called *mypic.jpg* located in the source_image folder, then create a
-thumbnail that is 75 X 50 pixels using the GD2 image_library. Since the
-maintain_ratio option is enabled, the thumb will be as close to the
-target width and height as possible while preserving the original aspect
-ratio. The thumbnail will be called *mypic_thumb.jpg* and located at
-the same level as *source_image*.
-
-.. note:: In order for the image class to be allowed to do any
-	processing, the folder containing the image files must have write
-	permissions.
-
-.. note:: Image processing can require a considerable amount of server
-	memory for some operations. If you are experiencing out of memory errors
-	while processing images you may need to limit their maximum size, and/or
-	adjust PHP memory limits.
-
-Processing Methods
-==================
-
-There are four available processing methods:
-
--  $this->image_lib->resize()
--  $this->image_lib->crop()
--  $this->image_lib->rotate()
--  $this->image_lib->watermark()
-
-These methods return boolean TRUE upon success and FALSE for failure.
-If they fail you can retrieve the error message using this function::
-
-	echo $this->image_lib->display_errors();
-
-A good practice is to use the processing function conditionally, showing an
-error upon failure, like this::
-
-	if ( ! $this->image_lib->resize())
-	{
-		echo $this->image_lib->display_errors();
-	}
-
-.. note:: You can optionally specify the HTML formatting to be applied to
-	the errors, by submitting the opening/closing tags in the function,
-	like this::
-
-	$this->image_lib->display_errors('<p>', '</p>');
-
-.. _processing-preferences:
-
-Preferences
-===========
-
-The preferences described below allow you to tailor the image processing
-to suit your needs.
-
-Note that not all preferences are available for every function. For
-example, the x/y axis preferences are only available for image cropping.
-Likewise, the width and height preferences have no effect on cropping.
-The "availability" column indicates which functions support a given
-preference.

-Setting preferences in a config file
-====================================
-
-If you prefer not to set preferences using the above method, you can
-instead put them into a config file. Simply create a new file called
-image_lib.php, add the $config array in that file. Then save the file
-in *config/image_lib.php* and it will be used automatically. You will
-NOT need to use the ``$this->image_lib->initialize()`` method if you save
-your preferences in a config file.

-******************
-Image Watermarking
-******************
-
-The Watermarking feature requires the GD/GD2 library.
-
-Two Types of Watermarking
-=========================
-
-There are two types of watermarking that you can use:
-
--  **Text**: The watermark message will be generated using text, either
-   with a True Type font that you specify, or using the native text
-   output that the GD library supports. If you use the True Type version
-   your GD installation must be compiled with True Type support (most
-   are, but not all).
--  **Overlay**: The watermark message will be generated by overlaying an
-   image (usually a transparent PNG or GIF) containing your watermark
-   over the source image.
-
-.. _watermarking:
-
-Watermarking an Image
-=====================
-
-Just as with the other methods (resizing, cropping, and rotating) the
-general process for watermarking involves setting the preferences
-corresponding to the action you intend to perform, then calling the
-watermark function. Here is an example::
-
-	$config['source_image']	= '/path/to/image/mypic.jpg';
-	$config['wm_text'] = 'Copyright 2006 - John Doe';
-	$config['wm_type'] = 'text';
-	$config['wm_font_path'] = './system/fonts/texb.ttf';
-	$config['wm_font_size']	= '16';
-	$config['wm_font_color'] = 'ffffff';
-	$config['wm_vrt_alignment'] = 'bottom';
-	$config['wm_hor_alignment'] = 'center';
-	$config['wm_padding'] = '20';
-
-	$this->image_lib->initialize($config); 
-
-	$this->image_lib->watermark();
-
-The above example will use a 16 pixel True Type font to create the text
-"Copyright 2006 - John Doe". The watermark will be positioned at the
-bottom/center of the image, 20 pixels from the bottom of the image.
-
-.. note:: In order for the image class to be allowed to do any
-	processing, the image file must have "write" file permissions
-	For example, 777.

-Class Reference

-
-.. php:class:: CI_Image_lib
-
-	.. php:method:: initialize([$props = array()])
-
-		:param	array	$props: Image processing preferences
-		:returns:	TRUE on success, FALSE in case of invalid settings
-		:rtype:	bool
-
-		Initializes the class for processing an image.
-
-	.. php:method:: resize()
-
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		The image resizing method lets you resize the original image, create a
-		copy (with or without resizing), or create a thumbnail image.
-
-		For practical purposes there is no difference between creating a copy
-		and creating a thumbnail except a thumb will have the thumbnail marker
-		as part of the name (i.e. mypic_thumb.jpg).
-
-		All preferences listed in the :ref:`processing-preferences` table are available for this
-		method except these three: *rotation_angle*, *x_axis* and *y_axis*.
-
-		**Creating a Thumbnail**
-
-		The resizing method will create a thumbnail file (and preserve the
-		original) if you set this preference to TRUE::
-
-			$config['create_thumb'] = TRUE;
-
-		This single preference determines whether a thumbnail is created or not.
-
-		**Creating a Copy**
-
-		The resizing method will create a copy of the image file (and preserve
-		the original) if you set a path and/or a new filename using this
-		preference::
-
-			$config['new_image'] = '/path/to/new_image.jpg';
-
-		Notes regarding this preference:
-
-		-  If only the new image name is specified it will be placed in the same
-		   folder as the original
-		-  If only the path is specified, the new image will be placed in the
-		   destination with the same name as the original.
-		-  If both the path and image name are specified it will placed in its
-		   own destination and given the new name.
-
-		**Resizing the Original Image**
-
-		If neither of the two preferences listed above (create_thumb, and
-		new_image) are used, the resizing method will instead target the
-		original image for processing.
-
-	.. php:method:: crop()
-
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		The cropping method works nearly identically to the resizing function
-		except it requires that you set preferences for the X and Y axis (in
-		pixels) specifying where to crop, like this::
-
-			$config['x_axis'] = 100;
-			$config['y_axis'] = 40;
-
-		All preferences listed in the :ref:`processing-preferences` table are available for this
-		method except these: *rotation_angle*, *create_thumb* and *new_image*.
-
-		Here's an example showing how you might crop an image::
-
-			$config['image_library'] = 'imagemagick';
-			$config['library_path'] = '/usr/X11R6/bin/';
-			$config['source_image']	= '/path/to/image/mypic.jpg';
-			$config['x_axis'] = 100;
-			$config['y_axis'] = 60;
-
-			$this->image_lib->initialize($config); 
-
-			if ( ! $this->image_lib->crop())
-			{
-				echo $this->image_lib->display_errors();
-			}
-
-		.. note:: Without a visual interface it is difficult to crop images, so this
-			method is not very useful unless you intend to build such an
-			interface. That's exactly what we did using for the photo gallery module
-			in ExpressionEngine, the CMS we develop. We added a JavaScript UI that
-			lets the cropping area be selected.
-
-	.. php:method:: rotate()
-
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		The image rotation method requires that the angle of rotation be set
-		via its preference::
-
-			$config['rotation_angle'] = '90';
-
-		There are 5 rotation options:
-
-		#. 90 - rotates counter-clockwise by 90 degrees.
-		#. 180 - rotates counter-clockwise by 180 degrees.
-		#. 270 - rotates counter-clockwise by 270 degrees.
-		#. hor - flips the image horizontally.
-		#. vrt - flips the image vertically.
-
-		Here's an example showing how you might rotate an image::
-
-			$config['image_library'] = 'netpbm';
-			$config['library_path'] = '/usr/bin/';
-			$config['source_image']	= '/path/to/image/mypic.jpg';
-			$config['rotation_angle'] = 'hor';
-
-			$this->image_lib->initialize($config); 
-
-			if ( ! $this->image_lib->rotate())
-			{
-				echo $this->image_lib->display_errors();
-			}
-
-	.. php:method:: watermark()
-
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		Creates a watermark over an image, please refer to the :ref:`watermarking`
-		section for more info.		
-
-	.. php:method:: clear()
-
-		:rtype:	void
-
-		The clear method resets all of the values used when processing an
-		image. You will want to call this if you are processing images in a
-		loop.
-
-		::
-
-			$this->image_lib->clear();
-
-	.. php:method:: display_errors([$open = '<p>[, $close = '</p>']])
-
-		:param	string	$open: Error message opening tag
-		:param	string	$close: Error message closing tag
-		:returns:	Error messages
-		:rtype:	string
-
-		Returns all detected errors formatted as a string.

-Input Class
-###########
-
-The Input Class serves two purposes:
-
-#. It pre-processes global input data for security.
-#. It provides some helper methods for fetching input data and pre-processing it.
-
-.. note:: This class is initialized automatically by the system so there
-	is no need to do it manually.
-

-Input Filtering
-***************
-
-Security Filtering
-==================
-
-The security filtering method is called automatically when a new
-:doc:`controller <../general/controllers>` is invoked. It does the
-following:
-
--  If ``$config['allow_get_array']`` is FALSE (default is TRUE), destroys
-   the global GET array.
--  Destroys all global variables in the event register_globals is
-   turned on.
--  Filters the GET/POST/COOKIE array keys, permitting only alpha-numeric
-   (and a few other) characters.
--  Provides XSS (Cross-site Scripting Hacks) filtering. This can be
-   enabled globally, or upon request.
--  Standardizes newline characters to ``PHP_EOL`` (\\n in UNIX-based OSes,
-   \\r\\n under Windows). This is configurable.
-
-XSS Filtering
-=============
-
-The Input class has the ability to filter input automatically to prevent
-cross-site scripting attacks. If you want the filter to run
-automatically every time it encounters POST or COOKIE data you can
-enable it by opening your *application/config/config.php* file and setting
-this::
-
-	$config['global_xss_filtering'] = TRUE;
-
-Please refer to the :doc:`Security class <security>` documentation for
-information on using XSS Filtering in your application.
-
-.. important:: The 'global_xss_filtering' setting is DEPRECATED and kept
-	solely for backwards-compatibility purposes. XSS escaping should
-	be performed on *output*, not *input*!
-
-*******************
-Accessing form data
-*******************
-
-Using POST, GET, COOKIE, or SERVER Data
-=======================================
-
-CodeIgniter comes with helper methods that let you fetch POST, GET,
-COOKIE or SERVER items. The main advantage of using the provided
-methods rather than fetching an item directly (``$_POST['something']``)
-is that the methods will check to see if the item is set and return
-NULL if not. This lets you conveniently use data without
-having to test whether an item exists first. In other words, normally
-you might do something like this::
-
-	$something = isset($_POST['something']) ? $_POST['something'] : NULL;
-
-With CodeIgniter's built in methods you can simply do this::
-
-	$something = $this->input->post('something');
-
-The main methods are:
-
--  ``$this->input->post()``
--  ``$this->input->get()``
--  ``$this->input->cookie()``
--  ``$this->input->server()``
-
-Using the php://input stream
-============================
-
-If you want to utilize the PUT, DELETE, PATCH or other exotic request
-methods, they can only be accessed via a special input stream, that
-can only be read once. This isn't as easy as just reading from e.g.
-the ``$_POST`` array, because it will always exist and you can try
-and access multiple variables without caring that you might only have
-one shot at all of the POST data.
-
-CodeIgniter will take care of that for you, and you can read the data
-from the **php://input** stream at any time, just by using the
-``$raw_input_stream`` property::
-
-	$this->input->raw_input_stream;
-
-Additionally if the input stream is form-encoded like $_POST you can 
-access its values by calling the
-``input_stream()`` method::
-
-	$this->input->input_stream('key');
-
-Similar to other methods such as ``get()`` and ``post()``, if the
-requested data is not found, it will return NULL and you can also
-decide whether to run the data through ``xss_clean()`` by passing
-a boolean value as the second parameter::
-
-	$this->input->input_stream('key', TRUE); // XSS Clean
-	$this->input->input_stream('key', FALSE); // No XSS filter
-
-.. note:: You can utilize ``method()`` in order to know if you're reading
-	PUT, DELETE or PATCH data.
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_Input
-
-	.. attribute:: $raw_input_stream
-		
-		Read only property that will return php://input data as is.
-		
-		The property can be read multiple times.
-
-	.. php:method:: post([$index = NULL[, $xss_clean = NULL]])
-
-		:param	mixed	$index: POST parameter name
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:returns:	$_POST if no parameters supplied, otherwise the POST value if found or NULL if not
-		:rtype:	mixed
-
-		The first parameter will contain the name of the POST item you are
-		looking for::
-
-			$this->input->post('some_data');
-
-		The method returns NULL if the item you are attempting to retrieve
-		does not exist.
-
-		The second optional parameter lets you run the data through the XSS
-		filter. It's enabled by setting the second parameter to boolean TRUE
-		or by setting your ``$config['global_xss_filtering']`` to TRUE.
-		::
-
-			$this->input->post('some_data', TRUE);
-
-		To return an array of all POST items call without any parameters.
-
-		To return all POST items and pass them through the XSS filter set the
-		first parameter NULL while setting the second parameter to boolean TRUE.
-		::
-
-			$this->input->post(NULL, TRUE); // returns all POST items with XSS filter
-			$this->input->post(NULL, FALSE); // returns all POST items without XSS filter
-
-		To return an array of multiple POST parameters, pass all the required keys
-		as an array.
-		::
-
-			$this->input->post(array('field1', 'field2'));
-
-		Same rule applied here, to retrieve the parameters with XSS filtering enabled, set the
-		second parameter to boolean TRUE.
-		::
-
-			$this->input->post(array('field1', 'field2'), TRUE);
-
-	.. php:method:: get([$index = NULL[, $xss_clean = NULL]])
-
-		:param	mixed	$index: GET parameter name
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:returns:	$_GET if no parameters supplied, otherwise the GET value if found or NULL if not
-		:rtype:	mixed
-
-		This method is identical to ``post()``, only it fetches GET data.
-		::
-
-			$this->input->get('some_data', TRUE);
-
-		To return an array of all GET items call without any parameters.
-
-		To return all GET items and pass them through the XSS filter set the
-		first parameter NULL while setting the second parameter to boolean TRUE.
-		::
-
-			$this->input->get(NULL, TRUE); // returns all GET items with XSS filter
-			$this->input->get(NULL, FALSE); // returns all GET items without XSS filtering
-
-		To return an array of multiple GET parameters, pass all the required keys
-		as an array.
-		::
-
-			$this->input->get(array('field1', 'field2'));
-
-		Same rule applied here, to retrieve the parameters with XSS filtering enabled, set the
-		second parameter to boolean TRUE.
-		::
-
-			$this->input->get(array('field1', 'field2'), TRUE);
-
-	.. php:method:: post_get($index[, $xss_clean = NULL])
-
-		:param	string	$index: POST/GET parameter name
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:returns:	POST/GET value if found, NULL if not
-		:rtype:	mixed
-
-		This method works pretty much the same way as ``post()`` and ``get()``,
-		only combined. It will search through both POST and GET streams for data,
-		looking in POST first, and then in GET::
-
-			$this->input->post_get('some_data', TRUE);
-
-	.. php:method:: get_post($index[, $xss_clean = NULL])
-
-		:param	string	$index: GET/POST parameter name
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:returns:	GET/POST value if found, NULL if not
-		:rtype:	mixed
-
-		This method works the same way as ``post_get()`` only it looks for GET
-		data first.
-
-			$this->input->get_post('some_data', TRUE);
-
-		.. note:: This method used to act EXACTLY like ``post_get()``, but it's
-			behavior has changed in CodeIgniter 3.0.
-
-	.. php:method:: cookie([$index = NULL[, $xss_clean = NULL]])
-
-		:param	mixed	$index: COOKIE name
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:returns:	$_COOKIE if no parameters supplied, otherwise the COOKIE value if found or NULL if not
-		:rtype:	mixed
-
-		This method is identical to ``post()`` and ``get()``, only it fetches cookie
-		data::
-
-			$this->input->cookie('some_cookie');
-			$this->input->cookie('some_cookie, TRUE); // with XSS filter
-
-		To return an array of multiple cookie values, pass all the required keys
-		as an array.
-		::
-
-			$this->input->cookie(array('some_cookie', 'some_cookie2'));
-
-		.. note:: Unlike the :doc:`Cookie Helper <../helpers/cookie_helper>`
-			function :php:func:`get_cookie()`, this method does NOT prepend
-			your configured ``$config['cookie_prefix']`` value.
-
-	.. php:method:: server($index[, $xss_clean = NULL])
-
-		:param	mixed	$index: Value name
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:returns:	$_SERVER item value if found, NULL if not
-		:rtype:	mixed
-
-		This method is identical to the ``post()``, ``get()`` and ``cookie()``
-		methods, only it fetches server data (``$_SERVER``)::
-
-			$this->input->server('some_data');
-
-		To return an array of multiple ``$_SERVER`` values, pass all the required keys
-		as an array.
-		::
-
-			$this->input->server(array('SERVER_PROTOCOL', 'REQUEST_URI'));
-
-	.. php:method:: input_stream([$index = NULL[, $xss_clean = NULL]])
-
-		:param	mixed	$index: Key name
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:returns:	Input stream array if no parameters supplied, otherwise the specified value if found or NULL if not
-		:rtype:	mixed
-
-		This method is identical to ``get()``, ``post()`` and ``cookie()``,
-		only it fetches the *php://input* stream data.
-
-	.. php:method:: set_cookie($name = ''[, $value = ''[, $expire = ''[, $domain = ''[, $path = '/'[, $prefix = ''[, $secure = NULL[, $httponly = NULL]]]]]]])
-
-		:param	mixed	$name: Cookie name or an array of parameters
-		:param	string	$value: Cookie value
-		:param	int	$expire: Cookie expiration time in seconds
-		:param	string	$domain: Cookie domain
-		:param	string	$path: Cookie path
-		:param	string	$prefix: Cookie name prefix
-		:param	bool	$secure: Whether to only transfer the cookie through HTTPS
-		:param	bool	$httponly: Whether to only make the cookie accessible for HTTP requests (no JavaScript)
-		:rtype:	void
-
-
-		Sets a cookie containing the values you specify. There are two ways to
-		pass information to this method so that a cookie can be set: Array
-		Method, and Discrete Parameters:
-
-		**Array Method**
-
-		Using this method, an associative array is passed to the first
-		parameter::
-
-			$cookie = array(
-				'name'   => 'The Cookie Name',
-				'value'  => 'The Value',
-				'expire' => '86500',
-				'domain' => '.some-domain.com',
-				'path'   => '/',
-				'prefix' => 'myprefix_',
-				'secure' => TRUE
-			);
-
-			$this->input->set_cookie($cookie);
-
-		**Notes**
-
-		Only the name and value are required. To delete a cookie set it with the
-		expiration blank.
-
-		The expiration is set in **seconds**, which will be added to the current
-		time. Do not include the time, but rather only the number of seconds
-		from *now* that you wish the cookie to be valid. If the expiration is
-		set to zero the cookie will only last as long as the browser is open.
-
-		For site-wide cookies regardless of how your site is requested, add your
-		URL to the **domain** starting with a period, like this:
-		.your-domain.com
-
-		The path is usually not needed since the method sets a root path.
-
-		The prefix is only needed if you need to avoid name collisions with
-		other identically named cookies for your server.
-
-		The *httponly* and *secure* flags, when omitted, will default to your
-		``$config['cookie_httponly']`` and ``$config['cookie_secure']`` settings.
-
-		**Discrete Parameters**
-
-		If you prefer, you can set the cookie by passing data using individual
-		parameters::
-
-			$this->input->set_cookie($name, $value, $expire, $domain, $path, $prefix, $secure);
-
-	.. php:method:: ip_address()
-
-		:returns:	Visitor's IP address or '0.0.0.0' if not valid
-		:rtype:	string
-
-		Returns the IP address for the current user. If the IP address is not
-		valid, the method will return '0.0.0.0'::
-
-			echo $this->input->ip_address();
-
-		.. important:: This method takes into account the ``$config['proxy_ips']``
-			setting and will return the reported HTTP_X_FORWARDED_FOR,
-			HTTP_CLIENT_IP, HTTP_X_CLIENT_IP or HTTP_X_CLUSTER_CLIENT_IP
-			address for the allowed IP addresses.
-
-	.. php:method:: valid_ip($ip[, $which = ''])
-
-		:param	string	$ip: IP address
-		:param	string	$which: IP protocol ('ipv4' or 'ipv6')
-		:returns:	TRUE if the address is valid, FALSE if not
-		:rtype:	bool
-
-		Takes an IP address as input and returns TRUE or FALSE (boolean) depending
-		on whether it is valid or not.
-
-		.. note:: The $this->input->ip_address() method above automatically
-			validates the IP address.
-
-		::
-
-			if ( ! $this->input->valid_ip($ip))
-			{
-				echo 'Not Valid';
-			}
-			else
-			{
-				echo 'Valid';
-			}
-
-		Accepts an optional second string parameter of 'ipv4' or 'ipv6' to specify
-		an IP format. The default checks for both formats.
-
-	.. php:method:: user_agent([$xss_clean = NULL])
-
-		:returns:	User agent string or NULL if not set
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:rtype:	mixed
-
-		Returns the user agent string (web browser) being used by the current user,
-		or NULL if it's not available.
-		::
-
-			echo $this->input->user_agent();
-
-		See the :doc:`User Agent Class <user_agent>` for methods which extract
-		information from the user agent string.
-
-	.. php:method:: request_headers([$xss_clean = FALSE])
-
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:returns:	An array of HTTP request headers
-		:rtype:	array
-
-		Returns an array of HTTP request headers.
-		Useful if running in a non-Apache environment where
-		`apache_request_headers() <http://php.net/apache_request_headers>`_
-		will not be supported.
-		::
-
-			$headers = $this->input->request_headers();
-
-	.. php:method:: get_request_header($index[, $xss_clean = FALSE])
-
-		:param	string	$index: HTTP request header name
-		:param	bool	$xss_clean: Whether to apply XSS filtering
-		:returns:	An HTTP request header or NULL if not found
-		:rtype:	string
-
-		Returns a single member of the request headers array or NULL
-		if the searched header is not found.
-		::
-
-			$this->input->get_request_header('some-header', TRUE);
-
-	.. php:method:: is_ajax_request()
-
-		:returns:	TRUE if it is an Ajax request, FALSE if not
-		:rtype:	bool
-
-		Checks to see if the HTTP_X_REQUESTED_WITH server header has been
-		set, and returns boolean TRUE if it is or FALSE if not.
-
-	.. php:method:: is_cli_request()
-
-		:returns:	TRUE if it is a CLI request, FALSE if not
-		:rtype:	bool
-
-		Checks to see if the application was run from the command-line
-		interface.
-
-		.. note:: This method checks both the PHP SAPI name currently in use
-			and if the ``STDIN`` constant is defined, which is usually a
-			failsafe way to see if PHP is being run via the command line.
-
-		::
-
-			$this->input->is_cli_request()
-
-		.. note:: This method is DEPRECATED and is now just an alias for the

-Javascript Class
-################
-
-CodeIgniter provides a library to help you with certain common functions
-that you may want to use with Javascript. Please note that CodeIgniter
-does not require the jQuery library to run, and that any scripting
-library will work equally well. The jQuery library is simply presented
-as a convenience if you choose to use it.
-
-.. important:: This library is DEPRECATED and should not be used. It has always
-	been with an 'experimental' status and is now no longer supported.
-	Currently only kept for backwards compatibility.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-**************************
-Using the Javascript Class
-**************************
-
-Initializing the Class
-======================
-
-To initialize the Javascript class manually in your controller
-constructor, use the ``$this->load->library()`` method. Currently,
-the only available library is jQuery, which will automatically be
-loaded like this::
-
-	$this->load->library('javascript');
-
-The Javascript class also accepts parameters:
-
-- js_library_driver (string) *default: 'jquery'*
-- autoload (bool) *default: TRUE*
-
-You may override the defaults by sending an associative array::
-
-	$this->load->library(
-		'javascript',
-		array(
-			'js_library_driver' => 'scripto',
-			'autoload' => FALSE
-		)
-	);
-
-Again, presently only 'jquery' is available. You may wish to set
-autoload to FALSE, though, if you do not want the jQuery library to
-automatically include a script tag for the main jQuery script file. This
-is useful if you are loading it from a location outside of CodeIgniter,
-or already have the script tag in your markup.
-
-Once loaded, the jQuery library object will be available using:
-
-	$this->javascript
-
-Setup and Configuration
-=======================
-
-Set these variables in your view
---------------------------------
-
-As a Javascript library, your files must be available to your
-application.
-
-As Javascript is a client side language, the library must be able to
-write content into your final output. This generally means a view.
-You'll need to include the following variables in the ``<head>``
-sections of your output.
-
-::
-
-	<?php echo $library_src;?>
-	<?php echo $script_head;?>
-
-
-``$library_src``, is where the actual library file will be loaded, as
-well as any subsequent plugin script calls; $script_head is where
-specific events, functions and other commands will be rendered.
-
-Set the path to the librarys with config items
-----------------------------------------------
-
-There are some configuration items in Javascript library. These can
-either be set in *application/config.php*, within its own
-*config/javascript.php* file, or within any controller usings the
-``set_item()`` function.
-
-An image to be used as an "ajax loader", or progress indicator. Without
-one, the simple text message of "loading" will appear when Ajax calls
-need to be made.
-
-::
-
-	$config['javascript_location'] = 'http://localhost/codeigniter/themes/js/jquery/';
-	$config['javascript_ajax_img'] = 'images/ajax-loader.gif';
-
-If you keep your files in the same directories they were downloaded
-from, then you need not set this configuration items.
-
-The jQuery Class
-================
-
-To initialize the jQuery class manually in your controller constructor,
-use the ``$this->load->library()`` method::
-
-	$this->load->library('javascript/jquery');
-
-You may send an optional parameter to determine whether or not a script
-tag for the main jQuery file will be automatically included when loading
-the library. It will be created by default. To prevent this, load the
-library as follows::
-
-	$this->load->library('javascript/jquery', FALSE);
-
-Once loaded, the jQuery library object will be available using:
-
-	$this->jquery
-
-jQuery Events
-=============
-
-Events are set using the following syntax.
-::
-
-	$this->jquery->event('element_path', code_to_run());
-
-In the above example:
-
--  "event" is any of blur, change, click, dblclick, error, focus, hover,
-   keydown, keyup, load, mousedown, mouseup, mouseover, mouseup, resize,
-   scroll, or unload.
--  "element_path" is any valid `jQuery selector
-   <http://api.jquery.com/category/selectors/>`_. Due to jQuery's unique
-   selector syntax, this is usually an element id, or CSS selector. For
-   example "#notice_area" would effect ``<div id="notice_area">``, and
-   "#content a.notice" would effect all anchors with a class of "notice"
-   in the div with id "content".
--  "``code_to_run()``" is script your write yourself, or an action such as
-   an effect from the jQuery library below.
-
-Effects
-=======
-
-The query library supports a powerful
-`Effects <http://api.jquery.com/category/effects/>`_ repertoire. Before an effect
-can be used, it must be loaded::
-
-	$this->jquery->effect([optional path] plugin name); // for example $this->jquery->effect('bounce');
-
-
-hide() / show()
----------------
-
-Each of this functions will affect the visibility of an item on your
-page. hide() will set an item invisible, show() will reveal it.
-
-::
-
-	$this->jquery->hide(target, optional speed, optional extra information);
-	$this->jquery->show(target, optional speed, optional extra information);
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "speed" is optional, and is set to either slow, normal, fast, or
-   alternatively a number of milliseconds.
--  "extra information" is optional, and could include a callback, or
-   other additional information.
-
-toggle()
---------
-
-toggle() will change the visibility of an item to the opposite of its
-current state, hiding visible elements, and revealing hidden ones.
-
-::
-
-	$this->jquery->toggle(target);
-
-
--  "target" will be any valid jQuery selector or selectors.
-
-animate()
----------
-
-::
-
-	 $this->jquery->animate(target, parameters, optional speed, optional extra information);
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "parameters" in jQuery would generally include a series of CSS
-   properties that you wish to change.
--  "speed" is optional, and is set to either slow, normal, fast, or
-   alternatively a number of milliseconds.
--  "extra information" is optional, and could include a callback, or
-   other additional information.
-
-For a full summary, see
-`http://api.jquery.com/animate/ <http://api.jquery.com/animate/>`_
-
-Here is an example of an animate() called on a div with an id of "note",
-and triggered by a click using the jQuery library's click() event.
-
-::
-
-	$params = array(
-	'height' => 80,
-	'width' => '50%',
-	'marginLeft' => 125
-	);
-	$this->jquery->click('#trigger', $this->jquery->animate('#note', $params, 'normal'));
-
-fadeIn() / fadeOut()
---------------------
-
-::
-
-	$this->jquery->fadeIn(target,  optional speed, optional extra information);
-	$this->jquery->fadeOut(target,  optional speed, optional extra information);
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "speed" is optional, and is set to either slow, normal, fast, or
-   alternatively a number of milliseconds.
--  "extra information" is optional, and could include a callback, or
-   other additional information.
-
-toggleClass()
--------------
-
-This function will add or remove a CSS class to its target.
-
-::
-
-	$this->jquery->toggleClass(target, class)
-
-
--  "target" will be any valid jQuery selector or selectors.
--  "class" is any CSS classname. Note that this class must be defined
-   and available in a CSS that is already loaded.
-
-fadeIn() / fadeOut()
---------------------
-
-These effects cause an element(s) to disappear or reappear over time.
-
-::
-
-	$this->jquery->fadeIn(target,  optional speed, optional extra information);
-	$this->jquery->fadeOut(target,  optional speed, optional extra information);
-

-Language Class
-##############
-
-The Language Class provides functions to retrieve language files and
-lines of text for purposes of internationalization.
-
-In your CodeIgniter **system** folder, you will find a **language** sub-directory
-containing a set of language files for the **english** idiom.
-The files in this directory (**system/language/english/**) define the regular messages,
-error messages, and other generally output terms or expressions, for the different parts
-of the CodeIgniter framework.
-
-You can create or incorporate your own language files, as needed, in order to provide
-application-specific error and other messages, or to provide translations of the core
-messages into other languages. These translations or additional messages would go inside
-your **application/language/** directory, with separate sub-directories for each idiom
-(for instance, 'french' or 'german').
-
-The CodeIgniter framework comes with a set of language files for the "english" idiom.
-Additional approved translations for different idioms may be found in the
-`CodeIgniter 3 Translations repositories <https://github.com/bcit-ci/codeigniter3-translations>`_.
-Each repository deals with a single idiom.
-
-When CodeIgniter loads language files, it will load the one in **system/language/**
-first and will then look for an override in your **application/language/** directory.
-
-.. note:: Each language should be stored in its own folder. For example,
-	the English files are located at: system/language/english
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-***************************
-Handling Multiple Languages
-***************************
-
-If you want to support multiple languages in your application, you would provide folders inside
-your **application/language/** directory for each of them, and you would specify the default
-language in your **application/config/config.php**.
-
-The **application/language/english/** directory would contain any additional language files
-needed by your application, for instance for error messages.
-
-Each of the other idiom-specific directories would contain the core language files that you
-obtained from the translations repositories, or that you translated yourself, as well as
-any additional ones needed by your application.
-
-You would store the language you are currently using, for instance in a session variable.
-
-Sample Language Files
-=====================
-
-::
-
-	system/
-		language/
-			english/
-				...
-				email_lang.php
-				form_validation_lang.php
-				...
-
-	application/
-		language/
-			english/
-				error_messages_lang.php
-			french/
-				...
-				email_lang.php
-				error_messages_lang.php
-				form_validation_lang.php
-				...
-
-Example of switching languages
-==============================
-
-::
-
-	$idiom = $this->session->get_userdata('language');
-	$this->lang->load('error_messages', $idiom);
-	$oops = $this->lang->line('message_key');
-
-********************
-Internationalization
-********************
-
-The Language class in CodeIgniter is meant to provide an easy and lightweight
-way to support multiplelanguages in your application. It is not meant to be a
-full implementation of what is commonly called `internationalization and localization
-<http://en.wikipedia.org/wiki/Internationalization_and_localization>`_.
-
-We use the term "idiom" to refer to a language using its common name,
-rather than using any of the international standards, such as "en", "en-US",
-or "en-CA-x-ca" for English and some of its variants.
-
-.. note:: There is nothing to prevent you from using those abbreviations in your application!
-
-************************
-Using the Language Class
-************************
-
-Creating Language Files
-=======================
-
-Language files must be named with **_lang.php** as the filename extension.
-For example, let's say you want to create a file containing error messages.
-You might name it: error_lang.php
-
-Within the file you will assign each line of text to an array called
-``$lang`` with this prototype::
-
-	$lang['language_key'] = 'The actual message to be shown';
-
-.. note:: It's a good practice to use a common prefix for all messages
-	in a given file to avoid collisions with similarly named items in other
-	files. For example, if you are creating error messages you might prefix
-	them with error\_
-
-::
-
-	$lang['error_email_missing'] = 'You must submit an email address';
-	$lang['error_url_missing'] = 'You must submit a URL';
-	$lang['error_username_missing'] = 'You must submit a username';
-
-Loading A Language File
-=======================
-
-In order to fetch a line from a particular file you must load the file
-first. Loading a language file is done with the following code::
-
-	$this->lang->load('filename', 'language');
-
-Where filename is the name of the file you wish to load (without the
-file extension), and language is the language set containing it (ie,
-english). If the second parameter is missing, the default language set
-in your **application/config/config.php** file will be used.
-
-You can also load multiple language files at the same time by passing an array of language files as first parameter.
-::
-
-	$this->lang->load(array('filename1', 'filename2'));
-
-.. note:: The *language* parameter can only consist of letters.
-
-Fetching a Line of Text
-=======================
-
-Once your desired language file is loaded you can access any line of
-text using this function::
-
-	$this->lang->line('language_key');
-
-Where *language_key* is the array key corresponding to the line you wish
-to show.
-
-You can optionally pass FALSE as the second argument of that method to
-disable error logging, in case you're not sure if the line exists::
-
-	$this->lang->line('misc_key', FALSE);
-
-.. note:: This method simply returns the line. It does not echo it.
-
-Using language lines as form labels
------------------------------------
-
-This feature has been deprecated from the language library and moved to
-the :php:func:`lang()` function of the :doc:`Language Helper
-<../helpers/language_helper>`.
-
-Auto-loading Languages
-======================
-
-If you find that you need a particular language globally throughout your
-application, you can tell CodeIgniter to :doc:`auto-load
-<../general/autoloader>` it during system initialization. This is done
-by opening the **application/config/autoload.php** file and adding the
-language(s) to the autoload array.

-Loader Class
-############
-
-Loader, as the name suggests, is used to load elements. These elements
-can be libraries (classes) :doc:`View files <../general/views>`,
-:doc:`Drivers <../general/drivers>`,
-:doc:`Helpers <../general/helpers>`,
-:doc:`Models <../general/models>`, or your own files.
-
-.. note:: This class is initialized automatically by the system so there
-	is no need to do it manually.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-**********************
-Application "Packages"
-**********************
-
-An application package allows for the easy distribution of complete sets
-of resources in a single directory, complete with its own libraries,
-models, helpers, config, and language files. It is recommended that
-these packages be placed in the application/third_party directory. Below
-is a sample map of an package directory.
-
-The following is an example of a directory for an application package
-named "Foo Bar".
-
-::
-
-	/application/third_party/foo_bar
-
-	config/
-	helpers/
-	language/
-	libraries/
-	models/
-
-Whatever the purpose of the "Foo Bar" application package, it has its
-own config files, helpers, language files, libraries, and models. To use
-these resources in your controllers, you first need to tell the Loader
-that you are going to be loading resources from a package, by adding the
-package path via the ``add_package_path()`` method.
-
-Package view files
-------------------
-
-By Default, package view files paths are set when ``add_package_path()``
-is called. View paths are looped through, and once a match is
-encountered that view is loaded.
-
-In this instance, it is possible for view naming collisions within
-packages to occur, and possibly the incorrect package being loaded. To
-ensure against this, set an optional second parameter of FALSE when
-calling ``add_package_path()``.
-
-::
-
-	$this->load->add_package_path(APPPATH.'my_app', FALSE);
-	$this->load->view('my_app_index'); // Loads
-	$this->load->view('welcome_message'); // Will not load the default welcome_message b/c the second param to add_package_path is FALSE
-
-	// Reset things
-	$this->load->remove_package_path(APPPATH.'my_app');
-
-	// Again without the second parameter:
-	$this->load->add_package_path(APPPATH.'my_app');
-	$this->load->view('my_app_index'); // Loads
-	$this->load->view('welcome_message'); // Loads
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_Loader
-
-	.. php:method:: library($library[, $params = NULL[, $object_name = NULL]])
-
-		:param	mixed	$library: Library name as a string or an array with multiple libraries
-		:param	array	$params: Optional array of parameters to pass to the loaded library's constructor
-		:param	string	$object_name: Optional object name to assign the library to
-		:returns:	CI_Loader instance (method chaining)
-		:rtype:	CI_Loader
-
-		This method is used to load core classes.
-
-		.. note:: We use the terms "class" and "library" interchangeably.
-
-		For example, if you would like to send email with CodeIgniter, the first
-		step is to load the email class within your controller::
-
-			$this->load->library('email');
-
-		Once loaded, the library will be ready for use, using ``$this->email``.
-
-		Library files can be stored in subdirectories within the main
-		"libraries" directory, or within your personal *application/libraries*
-		directory. To load a file located in a subdirectory, simply include the
-		path, relative to the "libraries" directory. For example, if you have
-		file located at::
-
-			libraries/flavors/Chocolate.php
-
-		You will load it using::
-
-			$this->load->library('flavors/chocolate');
-
-		You may nest the file in as many subdirectories as you want.
-
-		Additionally, multiple libraries can be loaded at the same time by
-		passing an array of libraries to the load method.
-		::
-
-			$this->load->library(array('email', 'table'));
-
-		**Setting options**
-
-		The second (optional) parameter allows you to optionally pass
-		configuration setting. You will typically pass these as an array::
-
-			$config = array (
-				'mailtype' => 'html',
-				'charset'  => 'utf-8,
-				'priority' => '1'
-			);
-
-			$this->load->library('email', $config);
-
-		Config options can usually also be set via a config file. Each library
-		is explained in detail in its own page, so please read the information
-		regarding each one you would like to use.
-
-		Please take note, when multiple libraries are supplied in an array for
-		the first parameter, each will receive the same parameter information.
-
-		**Assigning a Library to a different object name**
-
-		If the third (optional) parameter is blank, the library will usually be
-		assigned to an object with the same name as the library. For example, if
-		the library is named Calendar, it will be assigned to a variable named
-		``$this->calendar``.
-
-		If you prefer to set your own class names you can pass its value to the
-		third parameter::
-
-			$this->load->library('calendar', NULL, 'my_calendar');
-
-			// Calendar class is now accessed using:
-			$this->my_calendar
-
-		Please take note, when multiple libraries are supplied in an array for
-		the first parameter, this parameter is discarded.
-
-	.. php:method:: driver($library[, $params = NULL[, $object_name]])
-
-		:param	mixed	$library: Library name as a string or an array with multiple libraries
-		:param	array	$params: Optional array of parameters to pass to the loaded library's constructor
-		:param	string	$object_name: Optional object name to assign the library to
-		:returns:	CI_Loader instance (method chaining)
-		:rtype:	CI_Loader
-
-		This method is used to load driver libraries, acts very much like the
-		``library()`` method.
-
-		As an example, if you would like to use sessions with CodeIgniter, the first
-		step is to load the session driver within your controller::
-
-			$this->load->driver('session');
-
-		Once loaded, the library will be ready for use, using ``$this->session``.
-
-		Driver files must be stored in a subdirectory within the main
-		"libraries" directory, or within your personal *application/libraries*
-		directory. The subdirectory must match the parent class name. Read the
-		:doc:`Drivers <../general/drivers>` description for details.
-
-		Additionally, multiple driver libraries can be loaded at the same time by
-		passing an array of drivers to the load method.
-		::
-
-			$this->load->driver(array('session', 'cache'));
-
-		**Setting options**
-
-		The second (optional) parameter allows you to optionally pass
-		configuration settings. You will typically pass these as an array::
-
-			$config = array(
-				'sess_driver' => 'cookie',
-				'sess_encrypt_cookie'  => true,
-				'encryption_key' => 'mysecretkey'
-			);
-
-			$this->load->driver('session', $config);
-
-		Config options can usually also be set via a config file. Each library
-		is explained in detail in its own page, so please read the information
-		regarding each one you would like to use.
-
-		**Assigning a Driver to a different object name**
-
-		If the third (optional) parameter is blank, the library will be assigned
-		to an object with the same name as the parent class. For example, if
-		the library is named Session, it will be assigned to a variable named
-		``$this->session``.
-
-		If you prefer to set your own class names you can pass its value to the
-		third parameter::
-
-			$this->load->library('session', '', 'my_session');
-
-			// Session class is now accessed using:
-			$this->my_session
-
-	.. php:method:: view($view[, $vars = array()[, return = FALSE]])
-
-		:param	string	$view: View name
-		:param	array	$vars: An associative array of variables
-		:param	bool	$return: Whether to return the loaded view
-		:returns:	View content string if $return is set to TRUE, otherwise CI_Loader instance (method chaining)
-		:rtype:	mixed
-
-		This method is used to load your View files. If you haven't read the
-		:doc:`Views <../general/views>` section of the user guide it is
-		recommended that you do since it shows you how this method is
-		typically used.
-
-		The first parameter is required. It is the name of the view file you
-		would like to load.
-
-		.. note:: The .php file extension does not need to be specified unless
-			you use something other than .php.
-
-		The second **optional** parameter can take an associative array or an
-		object as input, which it runs through the PHP
-		`extract() <http://php.net/extract>`_ function to convert to variables
-		that can be used in your view files. Again, read the
-		:doc:`Views <../general/views>` page to learn how this might be useful.
-
-		The third **optional** parameter lets you change the behavior of the
-		method so that it returns data as a string rather than sending it to
-		your browser. This can be useful if you want to process the data in some
-		way. If you set the parameter to TRUE (boolean) it will return data. The
-		default behavior is FALSE, which sends it to your browser. Remember to
-		assign it to a variable if you want the data returned::
-
-			$string = $this->load->view('myfile', '', TRUE);
-
-	.. php:method:: vars($vars[, $val = ''])
-
-		:param	mixed	$vars: An array of variables or a single variable name
-		:param	mixed	$val: Optional variable value
-		:returns:	CI_Loader instance (method chaining)
-		:rtype:	CI_Loader
-
-		This method takes an associative array as input and generates
-		variables using the PHP `extract() <http://php.net/extract>`_
-		function. This method produces the same result as using the second
-		parameter of the ``$this->load->view()`` method above. The reason you
-		might want to use this method independently is if you would like to
-		set some global variables in the constructor of your controller and have
-		them become available in any view file loaded from any method. You can
-		have multiple calls to this method. The data get cached and merged
-		into one array for conversion to variables.
-
-	.. php:method:: get_var($key)
-
-		:param	string	$key: Variable name key
-		:returns:	Value if key is found, NULL if not
-		:rtype:	mixed
-
-		This method checks the associative array of variables available to
-		your views. This is useful if for any reason a var is set in a library
-		or another controller method using ``$this->load->vars()``.
-
-	.. php:method:: get_vars()
-
-		:returns:	An array of all assigned view variables
-		:rtype:	array
-
-		This method retrieves all variables available to your views.
-
-	.. php:method:: clear_vars()
-
-		:returns:	CI_Loader instance (method chaining)
-		:rtype:	CI_Loader
-
-		Clears cached view variables.
-
-	.. php:method:: model($model[, $name = ''[, $db_conn = FALSE]])
-
-		:param	mixed	$model: Model name or an array containing multiple models
-		:param	string	$name: Optional object name to assign the model to
-		:param	string	$db_conn: Optional database configuration group to load
-		:returns:	CI_Loader instance (method chaining)
-		:rtype:	CI_Loader
-
-		::
-
-			$this->load->model('model_name');
-
-
-		If your model is located in a subdirectory, include the relative path
-		from your models directory. For example, if you have a model located at
-		*application/models/blog/Queries.php* you'll load it using::
-
-			$this->load->model('blog/queries');
-
-		If you would like your model assigned to a different object name you can
-		specify it via the second parameter of the loading method::
-
-			$this->load->model('model_name', 'fubar');
-			$this->fubar->method();
-
-	.. php:method:: database([$params = ''[, $return = FALSE[, $query_builder = NULL]]])
-
-		:param	mixed	$params: Database group name or configuration options
-		:param	bool	$return: Whether to return the loaded database object
-		:param	bool	$query_builder: Whether to load the Query Builder
-		:returns:	Loaded CI_DB instance or FALSE on failure if $return is set to TRUE, otherwise CI_Loader instance (method chaining)
-		:rtype:	mixed
-
-		This method lets you load the database class. The two parameters are
-		**optional**. Please see the :doc:`database <../database/index>`
-		section for more info.
-
-	.. php:method:: dbforge([$db = NULL[, $return = FALSE]])
-
-		:param	object	$db: Database object
-		:param	bool	$return: Whether to return the Database Forge instance
-		:returns:	Loaded CI_DB_forge instance if $return is set to TRUE, otherwise CI_Loader instance (method chaining)
-		:rtype:	mixed
-
-		Loads the :doc:`Database Forge <../database/forge>` class, please refer
-		to that manual for more info.
-
-	.. php:method:: dbutil([$db = NULL[, $return = FALSE]])
-
-		:param	object	$db: Database object
-		:param	bool	$return: Whether to return the Database Utilities instance
-		:returns:	Loaded CI_DB_utility instance if $return is set to TRUE, otherwise CI_Loader instance (method chaining)
-		:rtype:	mixed
-
-		Loads the :doc:`Database Utilities <../database/utilities>` class, please
-		refer to that manual for more info.
-
-	.. php:method:: helper($helpers)
-
-		:param	mixed	$helpers: Helper name as a string or an array containing multiple helpers
-		:returns:	CI_Loader instance (method chaining)
-		:rtype:	CI_Loader
-
-		This method loads helper files, where file_name is the name of the
-		file, without the _helper.php extension.
-
-	.. php:method:: file($path[, $return = FALSE])
-
-		:param	string	$path: File path
-		:param	bool	$return: Whether to return the loaded file
-		:returns:	File contents if $return is set to TRUE, otherwise CI_Loader instance (method chaining)
-		:rtype:	mixed
-
-		This is a generic file loading method. Supply the filepath and name in
-		the first parameter and it will open and read the file. By default the
-		data is sent to your browser, just like a View file, but if you set the
-		second parameter to boolean TRUE it will instead return the data as a
-		string.
-
-	.. php:method:: language($files[, $lang = ''])
-
-		:param	mixed	$files: Language file name or an array of multiple language files
-		:param	string	$lang: Language name
-		:returns:	CI_Loader instance (method chaining)
-		:rtype:	CI_Loader
-
-		This method is an alias of the :doc:`language loading
-		method <language>`: ``$this->lang->load()``.
-
-	.. php:method:: config($file[, $use_sections = FALSE[, $fail_gracefully = FALSE]])
-
-		:param	string	$file: Configuration file name
-		:param	bool	$use_sections: Whether configuration values should be loaded into their own section
-		:param	bool	$fail_gracefully: Whether to just return FALSE in case of failure
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		This method is an alias of the :doc:`config file loading
-		method <config>`: ``$this->config->load()``
-
-	.. php:method:: is_loaded($class)
-
-		:param	string	$class: Class name
-		:returns:	Singleton property name if found, FALSE if not
-		:rtype:	mixed
-
-		Allows you to check if a class has already been loaded or not.
-
-		.. note:: The word "class" here refers to libraries and drivers.
-
-		If the requested class has been loaded, the method returns its assigned
-		name in the CI Super-object and FALSE if it's not::
-
-			$this->load->library('form_validation');
-			$this->load->is_loaded('Form_validation');	// returns 'form_validation'
-
-			$this->load->is_loaded('Nonexistent_library');	// returns FALSE
-
-		.. important:: If you have more than one instance of a class (assigned to
-			different properties), then the first one will be returned.
-
-		::
-
-			$this->load->library('form_validation', $config, 'fv');
-			$this->load->library('form_validation');
-
-			$this->load->is_loaded('Form_validation');	// returns 'fv'
-
-	.. php:method:: add_package_path($path[, $view_cascade = TRUE])
-
-		:param	string	$path: Path to add
-		:param	bool	$view_cascade: Whether to use cascading views
-		:returns:	CI_Loader instance (method chaining)
-		:rtype:	CI_Loader
-
-		Adding a package path instructs the Loader class to prepend a given path
-		for subsequent requests for resources. As an example, the "Foo Bar"
-		application package above has a library named Foo_bar.php. In our
-		controller, we'd do the following::
-
-			$this->load->add_package_path(APPPATH.'third_party/foo_bar/')
-				->library('foo_bar');
-
-	.. php:method:: remove_package_path([$path = ''])
-
-		:param	string	$path: Path to remove
-		:returns:	CI_Loader instance (method chaining)
-		:rtype:	CI_Loader
-
-		When your controller is finished using resources from an application
-		package, and particularly if you have other application packages you
-		want to work with, you may wish to remove the package path so the Loader
-		no longer looks in that directory for resources. To remove the last path
-		added, simply call the method with no parameters.
-
-		Or to remove a specific package path, specify the same path previously
-		given to ``add_package_path()`` for a package.::
-
-			$this->load->remove_package_path(APPPATH.'third_party/foo_bar/');
-
-	.. php:method:: get_package_paths([$include_base = TRUE])
-
-		:param	bool	$include_base: Whether to include BASEPATH
-		:returns:	An array of package paths
-		:rtype:	array
-
-		Returns all currently available package paths.

-Migrations Class
-################
-
-Migrations are a convenient way for you to alter your database in a 
-structured and organized manner. You could edit fragments of SQL by hand 
-but you would then be responsible for telling other developers that they 
-need to go and run them. You would also have to keep track of which changes 
-need to be run against the production machines next time you deploy.
-
-The database table **migration** tracks which migrations have already been 
-run so all you have to do is update your application files and 
-call ``$this->migration->current()`` to work out which migrations should be run. 
-The current version is found in **application/config/migration.php**.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-********************
-Migration file names
-********************
-
-Each Migration is run in numeric order forward or backwards depending on the
-method taken. Two numbering styles are available:
-
-* **Sequential:** each migration is numbered in sequence, starting with **001**.
-  Each number must be three digits, and there must not be any gaps in the
-  sequence. (This was the numbering scheme prior to CodeIgniter 3.0.)
-* **Timestamp:** each migration is numbered using the timestamp when the migration
-  was created, in **YYYYMMDDHHIISS** format (e.g. **20121031100537**). This
-  helps prevent numbering conflicts when working in a team environment, and is
-  the preferred scheme in CodeIgniter 3.0 and later.
-
-The desired style may be selected using the ``$config['migration_type']``
-setting in your *application/config/migration.php* file.
-
-Regardless of which numbering style you choose to use, prefix your migration
-files with the migration number followed by an underscore and a descriptive
-name for the migration. For example:
-
-* 001_add_blog.php (sequential numbering)
-* 20121031100537_add_blog.php (timestamp numbering)
-
-******************
-Create a Migration
-******************
-	
-This will be the first migration for a new site which has a blog. All 
-migrations go in the **application/migrations/** directory and have names such 
-as *20121031100537_add_blog.php*.
-::
-
-	<?php
-
-	defined('BASEPATH') OR exit('No direct script access allowed');
-
-	class Migration_Add_blog extends CI_Migration {
-
-		public function up()
-		{
-			$this->dbforge->add_field(array(
-				'blog_id' => array(
-					'type' => 'INT',
-					'constraint' => 5,
-					'unsigned' => TRUE,
-					'auto_increment' => TRUE
-				),
-				'blog_title' => array(
-					'type' => 'VARCHAR',
-					'constraint' => '100',
-				),
-				'blog_description' => array(
-					'type' => 'TEXT',
-					'null' => TRUE,
-				),
-			));
-			$this->dbforge->add_key('blog_id', TRUE);
-			$this->dbforge->create_table('blog');
-		}
-
-		public function down()
-		{
-			$this->dbforge->drop_table('blog');
-		}
-	}
-
-Then in **application/config/migration.php** set ``$config['migration_version'] = 20121031100537;``.
-
-*************
-Usage Example
-*************
-
-In this example some simple code is placed in **application/controllers/Migrate.php** 
-to update the schema.::
-
-	<?php
-	
-	class Migrate extends CI_Controller
-	{
-
-		public function index()
-		{
-			$this->load->library('migration');
-
-			if ($this->migration->current() === FALSE)
-			{
-				show_error($this->migration->error_string());
-			}
-		}
-
-	}

-Output Class
-############
-
-The Output class is a core class with one main function: To send the
-finalized web page to the requesting browser. It is also responsible for
-:doc:`caching <../general/caching>` your web pages, if you use that
-feature.
-
-.. note:: This class is initialized automatically by the system so there
-	is no need to do it manually.
-
-Under normal circumstances you won't even notice the Output class since
-it works transparently without your intervention. For example, when you
-use the :doc:`Loader <../libraries/loader>` class to load a view file,
-it's automatically passed to the Output class, which will be called
-automatically by CodeIgniter at the end of system execution. It is
-possible, however, for you to manually intervene with the output if you
-need to.

-Pagination Class
-################
-
-CodeIgniter's Pagination class is very easy to use, and it is 100%
-customizable, either dynamically or via stored preferences.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-If you are not familiar with the term "pagination", it refers to links
-that allows you to navigate from page to page, like this::
-
-	« First  < 1 2 3 4 5 >  Last »
-
-*******
-Example
-*******
-
-Here is a simple example showing how to create pagination in one of your
-:doc:`controller <../general/controllers>` methods::
-
-	$this->load->library('pagination');
-
-	$config['base_url'] = 'http://example.com/index.php/test/page/';
-	$config['total_rows'] = 200;
-	$config['per_page'] = 20;
-
-	$this->pagination->initialize($config);
-
-	echo $this->pagination->create_links();
-
-Notes
-=====
-
-The ``$config`` array contains your configuration variables. It is passed to
-the ``$this->pagination->initialize()`` method as shown above. Although
-there are some twenty items you can configure, at minimum you need the
-three shown. Here is a description of what those items represent:
-
--  **base_url** This is the full URL to the controller class/function
-   containing your pagination. In the example above, it is pointing to a
-   controller called "Test" and a function called "page". Keep in mind
-   that you can :doc:`re-route your URI <../general/routing>` if you
-   need a different structure.
--  **total_rows** This number represents the total rows in the result
-   set you are creating pagination for. Typically this number will be
-   the total rows that your database query returned.
--  **per_page** The number of items you intend to show per page. In the
-   above example, you would be showing 20 items per page.
-
-The ``create_links()`` method returns an empty string when there is no
-pagination to show.
-
-Setting preferences in a config file
-====================================
-
-If you prefer not to set preferences using the above method, you can
-instead put them into a config file. Simply create a new file called
-pagination.php, add the ``$config`` array in that file. Then save the file
-in *application/config/pagination.php* and it will be used automatically.
-You will NOT need to use ``$this->pagination->initialize()`` if you save
-your preferences in a config file.
-
-**************************
-Customizing the Pagination
-**************************
-
-The following is a list of all the preferences you can pass to the
-initialization function to tailor the display.
-
-**$config['uri_segment'] = 3;**
-
-The pagination function automatically determines which segment of your
-URI contains the page number. If you need something different you can
-specify it.
-
-**$config['num_links'] = 2;**
-
-The number of "digit" links you would like before and after the selected
-page number. For example, the number 2 will place two digits on either
-side, as in the example links at the very top of this page.
-
-**$config['use_page_numbers'] = TRUE;**
-
-By default, the URI segment will use the starting index for the items
-you are paginating. If you prefer to show the the actual page number,
-set this to TRUE.
-
-**$config['page_query_string'] = TRUE;**
-
-By default, the pagination library assume you are using :doc:`URI
-Segments <../general/urls>`, and constructs your links something
-like::
-
-	http://example.com/index.php/test/page/20
-
-If you have ``$config['enable_query_strings']`` set to TRUE your links
-will automatically be re-written using Query Strings. This option can
-also be explicitly set. Using ``$config['page_query_string']`` set to TRUE,
-the pagination link will become::
-
-	http://example.com/index.php?c=test&m=page&per_page=20
-
-Note that "per_page" is the default query string passed, however can be
-configured using ``$config['query_string_segment'] = 'your_string'``
-
-**$config['reuse_query_string'] = FALSE;**
-
-By default your Query String arguments (nothing to do with other
-query string options) will be ignored. Setting this config to
-TRUE will add existing query string arguments back into the
-URL after the URI segment and before the suffix.::
-
-	http://example.com/index.php/test/page/20?query=search%term
-
-This helps you mix together normal :doc:`URI Segments <../general/urls>`
-as well as query string arguments, which until 3.0 was not possible.
-
-**$config['prefix'] = '';**
-
-A custom prefix added to the path. The prefix value will be right before
-the offset segment.
-
-**$config['suffix'] = '';**
-
-A custom suffix added to the path. The sufix value will be right after
-the offset segment.
-
-**$config['use_global_url_suffix'] = FALSE;**
-
-When set to TRUE, it will **override** the ``$config['suffix']`` value and
-instead set it to the one that you have in ``$config['url_suffix']`` in
-your **application/config/config.php** file.
-
-***********************
-Adding Enclosing Markup
-***********************
-
-If you would like to surround the entire pagination with some markup you
-can do it with these two preferences:
-
-**$config['full_tag_open'] = '<p>';**
-
-The opening tag placed on the left side of the entire result.
-
-**$config['full_tag_close'] = '</p>';**
-
-The closing tag placed on the right side of the entire result.
-
-**************************
-Customizing the First Link
-**************************
-
-**$config['first_link'] = 'First';**
-
-The text you would like shown in the "first" link on the left. If you do
-not want this link rendered, you can set its value to FALSE.
-
-.. note:: This value can also be translated via a language file.
-
-**$config['first_tag_open'] = '<div>';**
-
-The opening tag for the "first" link.
-
-**$config['first_tag_close'] = '</div>';**
-
-The closing tag for the "first" link.
-
-**$config['first_url'] = '';**
-
-An alternative URL to use for the "first page" link.
-
-*************************
-Customizing the Last Link
-*************************
-
-**$config['last_link'] = 'Last';**
-
-The text you would like shown in the "last" link on the right. If you do
-not want this link rendered, you can set its value to FALSE.
-
-.. note:: This value can also be translated via a language file.
-
-**$config['last_tag_open'] = '<div>';**
-
-The opening tag for the "last" link.
-
-**$config['last_tag_close'] = '</div>';**
-
-The closing tag for the "last" link.
-
-***************************
-Customizing the "Next" Link
-***************************
-
-**$config['next_link'] = '&gt;';**
-
-The text you would like shown in the "next" page link. If you do not
-want this link rendered, you can set its value to FALSE.
-
-.. note:: This value can also be translated via a language file.
-
-**$config['next_tag_open'] = '<div>';**
-
-The opening tag for the "next" link.
-
-**$config['next_tag_close'] = '</div>';**
-
-The closing tag for the "next" link.
-
-*******************************
-Customizing the "Previous" Link
-*******************************
-
-**$config['prev_link'] = '&lt;';**

-Template Parser Class
-#####################
-
-The Template Parser Class can perform simple text substitution for 
-pseudo-variables contained within your view files. 
-It can parse simple variables or variable tag pairs. 
-
-If you've never used a template engine,
-pseudo-variable names are enclosed in braces, like this::
-
-	<html>
-		<head>
-			<title>{blog_title}</title>
-		</head>
-		<body>
-			<h3>{blog_heading}</h3>
-
-		{blog_entries}
-			<h5>{title}</h5>
-			<p>{body}</p>
-		{/blog_entries}
-
-		</body>
-	</html>
-
-These variables are not actual PHP variables, but rather plain text
-representations that allow you to eliminate PHP from your templates
-(view files).
-
-.. note:: CodeIgniter does **not** require you to use this class since
-	using pure PHP in your view pages lets them run a little faster.
-	However, some developers prefer to use a template engine if
-        they work with designers who they feel would find some
-        confusion working with PHP.
-
-.. important:: The Template Parser Class is **not** a full-blown
-	template parsing solution. We've kept it very lean on purpose in order
-	to maintain maximum performance.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-*******************************
-Using the Template Parser Class
-*******************************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Parser class is initialized
-in your controller using the ``$this->load->library()`` method::
-
-	$this->load->library('parser');
-
-Once loaded, the Parser library object will be available using:
-$this->parser
-
-Parsing templates
-=================
-
-You can use the ``parse()`` method to parse (or render) simple templates,
-like this::
-
-	$data = array(
-		'blog_title' => 'My Blog Title',
-		'blog_heading' => 'My Blog Heading'
-	);
-
-	$this->parser->parse('blog_template', $data);
-
-The first parameter contains the name of the :doc:`view
-file <../general/views>` (in this example the file would be called
-blog_template.php), and the second parameter contains an associative
-array of data to be replaced in the template. In the above example, the
-template would contain two variables: {blog_title} and {blog_heading}
-
-There is no need to "echo" or do something with the data returned by
-$this->parser->parse(). It is automatically passed to the output class
-to be sent to the browser. However, if you do want the data returned
-instead of sent to the output class you can pass TRUE (boolean) as the
-third parameter::
-
-	$string = $this->parser->parse('blog_template', $data, TRUE);
-
-Variable Pairs
-==============
-
-The above example code allows simple variables to be replaced. What if
-you would like an entire block of variables to be repeated, with each
-iteration containing new values? Consider the template example we showed
-at the top of the page::
-
-	<html>
-		<head>
-			<title>{blog_title}</title>
-		</head>
-		<body>
-			<h3>{blog_heading}</h3>
-
-		{blog_entries}
-			<h5>{title}</h5>
-			<p>{body}</p>
-		{/blog_entries}
-
-		</body>
-	</html>
-
-In the above code you'll notice a pair of variables: {blog_entries}
-data... {/blog_entries}. In a case like this, the entire chunk of data
-between these pairs would be repeated multiple times, corresponding to
-the number of rows in the "blog_entries" element of the parameters array.
-
-Parsing variable pairs is done using the identical code shown above to
-parse single variables, except, you will add a multi-dimensional array
-corresponding to your variable pair data. Consider this example::
-
-	$this->load->library('parser');
-
-	$data = array(
-		'blog_title'   => 'My Blog Title',
-		'blog_heading' => 'My Blog Heading',
-		'blog_entries' => array(
-			array('title' => 'Title 1', 'body' => 'Body 1'),
-			array('title' => 'Title 2', 'body' => 'Body 2'),
-			array('title' => 'Title 3', 'body' => 'Body 3'),
-			array('title' => 'Title 4', 'body' => 'Body 4'),
-			array('title' => 'Title 5', 'body' => 'Body 5')
-		)
-	);
-
-	$this->parser->parse('blog_template', $data);
-
-If your "pair" data is coming from a database result, which is already a
-multi-dimensional array, you can simply use the database ``result_array()``
-method::
-
-	$query = $this->db->query("SELECT * FROM blog");
-
-	$this->load->library('parser');
-
-	$data = array(
-		'blog_title'   => 'My Blog Title',
-		'blog_heading' => 'My Blog Heading',
-		'blog_entries' => $query->result_array()
-	);
-
-	$this->parser->parse('blog_template', $data);
-
-Usage Notes
-===========
-
-If you include substitution parameters that are not referenced in your
-template, they are ignored::
-
-	$template = 'Hello, {firstname} {lastname}';
-	$data = array(
-		'title' => 'Mr',
-		'firstname' => 'John',
-		'lastname' => 'Doe'
-	);
-	$this->parser->parse_string($template, $data);
-
-	// Result: Hello, John Doe
-
-If you do not include a substitution parameter that is referenced in your
-template, the original pseudo-variable is shown in the result::
-
-	$template = 'Hello, {firstname} {initials} {lastname}';
-	$data = array(
-		'title' => 'Mr',
-		'firstname' => 'John',
-		'lastname' => 'Doe'
-	);
-	$this->parser->parse_string($template, $data);
-
-	// Result: Hello, John {initials} Doe
-
-If you provide a string substitution parameter when an array is expected,
-i.e. for a variable pair, the substitution is done for the opening variable
-pair tag, but the closing variable pair tag is not rendered properly::
-
-	$template = 'Hello, {firstname} {lastname} ({degrees}{degree} {/degrees})';
-	$data = array(
-		'degrees' => 'Mr',
-		'firstname' => 'John',
-		'lastname' => 'Doe',
-		'titles' => array(
-			array('degree' => 'BSc'),
-			array('degree' => 'PhD')
-		)
-	);
-	$this->parser->parse_string($template, $data);
-
-	// Result: Hello, John Doe (Mr{degree} {/degrees})
-
-If you name one of your individual substitution parameters the same as one
-used inside a variable pair, the results may not be as expected::
-
-	$template = 'Hello, {firstname} {lastname} ({degrees}{degree} {/degrees})';
-	$data = array(
-		'degree' => 'Mr',
-		'firstname' => 'John',
-		'lastname' => 'Doe',
-		'degrees' => array(
-			array('degree' => 'BSc'),
-			array('degree' => 'PhD')
-		)
-	);
-	$this->parser->parse_string($template, $data);
-
-	// Result: Hello, John Doe (Mr Mr )
-
-View Fragments
-==============
-
-You do not have to use variable pairs to get the effect of iteration in
-your views. It is possible to use a view fragment for what would be inside
-a variable pair, and to control the iteration in your controller instead
-of in the view.
-
-An example with the iteration controlled in the view::
-
-	$template = '<ul>{menuitems}
-		<li><a href="{link}">{title}</a></li>
-	{/menuitems}</ul>';
-
-	$data = array(
-		'menuitems' => array(
-			array('title' => 'First Link', 'link' => '/first'),
-			array('title' => 'Second Link', 'link' => '/second'),
-		)
-	);
-	$this->parser->parse_string($template, $data);
-
-Result::
-
-	<ul>
-		<li><a href="/first">First Link</a></li>
-		<li><a href="/second">Second Link</a></li>
-	</ul>
-
-An example with the iteration controlled in the controller, 
-using a view fragment::
-
-	$temp = '';
-	$template1 = '<li><a href="{link}">{title}</a></li>';
-	$data1 = array(
-		array('title' => 'First Link', 'link' => '/first'),
-		array('title' => 'Second Link', 'link' => '/second'),
-	);
-
-	foreach ($data1 as $menuitem)
-	{
-		$temp .= $this->parser->parse_string($template1, $menuitem, TRUE);
-	}
-
-	$template = '<ul>{menuitems}</ul>';
-	$data = array(
-		'menuitems' => $temp
-	);
-	$this->parser->parse_string($template, $data);
-
-Result::
-
-	<ul>
-		<li><a href="/first">First Link</a></li>
-		<li><a href="/second">Second Link</a></li>
-	</ul>

-XSS Filtering
-*************
-
-CodeIgniter comes with a Cross Site Scripting prevention filter, which
-looks for commonly used techniques to trigger JavaScript or other types
-of code that attempt to hijack cookies or do other malicious things.
-If anything disallowed is encountered it is rendered safe by converting
-the data to character entities.
-
-To filter data through the XSS filter use the ``xss_clean()`` method::
-
-	$data = $this->security->xss_clean($data);
-
-An optional second parameter, *is_image*, allows this function to be used
-to test images for potential XSS attacks, useful for file upload
-security. When this second parameter is set to TRUE, instead of
-returning an altered string, the function returns TRUE if the image is
-safe, and FALSE if it contained potentially malicious information that a
-browser may attempt to execute.
-
-::
-
-	if ($this->security->xss_clean($file, TRUE) === FALSE)
-	{
-		// file failed the XSS test
-	}
-
-.. important:: If you want to filter HTML attribute values, use
-	:php:func:`html_escape()` instead!
-
-*********************************
-Cross-site request forgery (CSRF)
-*********************************
-
-You can enable CSRF protection by altering your **application/config/config.php**
-file in the following way::
-
-	$config['csrf_protection'] = TRUE;
-
-If you use the :doc:`form helper <../helpers/form_helper>`, then
-:func:`form_open()` will automatically insert a hidden csrf field in
-your forms. If not, then you can use ``get_csrf_token_name()``
-and ``get_csrf_hash()``
-::
-
-	$csrf = array(
-		'name' => $this->security->get_csrf_token_name(),
-		'hash' => $this->security->get_csrf_hash()
-	);
-
-	...
-
-	<input type="hidden" name="<?=$csrf['name'];?>" value="<?=$csrf['hash'];?>" />
-
-Tokens may be either regenerated on every submission (default) or
-kept the same throughout the life of the CSRF cookie. The default
-regeneration of tokens provides stricter security, but may result
-in usability concerns as other tokens become invalid (back/forward
-navigation, multiple tabs/windows, asynchronous actions, etc). You
-may alter this behavior by editing the following config parameter
-
-::
-
-	$config['csrf_regenerate'] = TRUE;
-
-Select URIs can be whitelisted from csrf protection (for example API
-endpoints expecting externally POSTed content). You can add these URIs
-by editing the 'csrf_exclude_uris' config parameter::
-
-	$config['csrf_exclude_uris'] = array('api/person/add');
-
-Regular expressions are also supported (case-insensitive)::
-
-	$config['csrf_exclude_uris'] = array(
-		'api/record/[0-9]+',
-		'api/title/[a-z]+'
-	);

-###############
-Session Library
-###############
-
-The Session class permits you maintain a user's "state" and track their
-activity while they browse your site.
-
-CodeIgniter comes with a few session storage drivers:
-
-  - files (default; file-system based)
-  - database
-  - redis
-  - memcached
-
-In addition, you may create your own, custom session drivers based on other
-kinds of storage, while still taking advantage of the features of the
-Session class.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-***********************
-Using the Session Class
-***********************
-
-Initializing a Session
-======================
-
-Sessions will typically run globally with each page load, so the Session
-class should either be initialized in your :doc:`controller
-<../general/controllers>` constructors, or it can be :doc:`auto-loaded
-<../general/autoloader>` by the system.
-For the most part the session class will run unattended in the background,
-so simply initializing the class will cause it to read, create, and update
-sessions when necessary.
-
-To initialize the Session class manually in your controller constructor,
-use the ``$this->load->library()`` method::
-
-	$this->load->library('session');
-
-Once loaded, the Sessions library object will be available using::
-
-	$this->session
-
-.. important:: Because the :doc:`Loader Class </libraries/loader>` is instantiated
-	by CodeIgniter's base controller, make sure to call
-	``parent::__construct()`` before trying to load a library from
-	inside a controller constructor.
-
-How do Sessions work?
-=====================
-
-When a page is loaded, the session class will check to see if valid
-session cookie is sent by the user's browser. If a sessions cookie does
-**not** exist (or if it doesn't match one stored on the server or has
-expired) a new session will be created and saved.
-
-If a valid session does exist, its information will be updated. With each
-update, the session ID may be regenerated if configured to do so.
-
-It's important for you to understand that once initialized, the Session
-class runs automatically. There is nothing you need to do to cause the
-above behavior to happen. You can, as you'll see below, work with session
-data, but the process of reading, writing, and updating a session is
-automatic.
-
-.. note:: Under CLI, the Session library will automatically halt itself,
-	as this is a concept based entirely on the HTTP protocol.
-
-A note about concurrency
-------------------------
-
-Unless you're developing a website with heavy AJAX usage, you can skip this
-section. If you are, however, and if you're experiencing performance
-issues, then this note is exactly what you're looking for.
-
-Sessions in previous versions of CodeIgniter didn't implement locking,
-which meant that two HTTP requests using the same session could run exactly
-at the same time. To use a more appropriate technical term - requests were
-non-blocking.
-
-However, non-blocking requests in the context of sessions also means
-unsafe, because modifications to session data (or session ID regeneration)
-in one request can interfere with the execution of a second, concurrent
-request. This detail was at the root of many issues and the main reason why
-CodeIgniter 3.0 has a completely re-written Session library.
-
-Why are we telling you this? Because it is likely that after trying to
-find the reason for your performance issues, you may conclude that locking
-is the issue and therefore look into how to remove the locks ...
-
-DO NOT DO THAT! Removing locks would be **wrong** and it will cause you
-more problems!
-
-Locking is not the issue, it is a solution. Your issue is that you still
-have the session open, while you've already processed it and therefore no
-longer need it. So, what you need is to close the session for the
-current request after you no longer need it.
-
-Long story short - call ``session_write_close()`` once you no longer need
-anything to do with session variables.
-
-What is Session Data?
-=====================
-
-Session data is simply an array associated with a particular session ID
-(cookie).
-
-If you've used sessions in PHP before, you should be familiar with PHP's
-`$_SESSION superglobal <http://php.net/manual/en/reserved.variables.session.php>`_
-(if not, please read the content on that link).
-
-CodeIgniter gives access to its session data through the same means, as it
-uses the session handlers' mechanism provided by PHP. Using session data is
-as simple as manipulating (read, set and unset values) the ``$_SESSION``
-array.
-
-In addition, CodeIgniter also provides 2 special types of session data
-that are further explained below: flashdata and tempdata.
-
-.. note:: In previous versions, regular session data in CodeIgniter was
-	referred to as 'userdata'. Have this in mind if that term is used
-	elsewhere in the manual. Most of it is written to explain how
-	the custom 'userdata' methods work.
-
-Retrieving Session Data
-=======================
-
-Any piece of information from the session array is available through the
-``$_SESSION`` superglobal::
-
-	$_SESSION['item']
-
-Or through the magic getter::
-
-	$this->session->item
-
-And for backwards compatibility, through the ``userdata()`` method::
-
-	$this->session->userdata('item');
-
-Where item is the array key corresponding to the item you wish to fetch.
-For example, to assign a previously stored 'name' item to the ``$name``
-variable, you will do this::
-
-	$name = $_SESSION['name'];
-
-	// or:
-
-	$name = $this->session->name
-
-	// or:
-
-	$name = $this->session->userdata('name');
-
-.. note:: The ``userdata()`` method returns NULL if the item you are trying
-	to access does not exist.
-
-If you want to retrieve all of the existing userdata, you can simply
-omit the item key (magic getter only works for properties)::
-
-	$_SESSION
-
-	// or:
-
-	$this->session->userdata();
-
-Adding Session Data
-===================
-
-Let's say a particular user logs into your site. Once authenticated, you
-could add their username and e-mail address to the session, making that
-data globally available to you without having to run a database query when
-you need it.
-
-You can simply assign data to the ``$_SESSION`` array, as with any other
-variable. Or as a property of ``$this->session``.
-
-Alternatively, the old method of assigning it as "userdata" is also
-available. That however passing an array containing your new data to the
-``set_userdata()`` method::
-
-	$this->session->set_userdata($array);
-
-Where ``$array`` is an associative array containing your new data. Here's
-an example::
-
-	$newdata = array(
-		'username'  => 'johndoe',
-		'email'     => 'johndoe@some-site.com',
-		'logged_in' => TRUE
-	);
-
-	$this->session->set_userdata($newdata);
-
-If you want to add userdata one value at a time, ``set_userdata()`` also
-supports this syntax::
-
-	$this->session->set_userdata('some_name', 'some_value');
-
-If you want to verify that a session value exists, simply check with
-``isset()``::
-
-	// returns FALSE if the 'some_name' item doesn't exist or is NULL,
-	// TRUE otherwise:
-	isset($_SESSION['some_name'])
-
-Or you can call ``has_userdata()``::
-
-	$this->session->has_userdata('some_name');
-
-Removing Session Data
-=====================
-
-Just as with any other variable, unsetting a value in ``$_SESSION`` can be
-done through ``unset()``::
-
-	unset($_SESSION['some_name']);
-
-	// or multiple values:
-
-	unset(
-		$_SESSION['some_name'],
-		$_SESSION['another_name']
-	);
-
-Also, just as ``set_userdata()`` can be used to add information to a
-session, ``unset_userdata()`` can be used to remove it, by passing the
-session key. For example, if you wanted to remove 'some_name' from your
-session data array::
-
-	$this->session->unset_userdata('some_name');
-
-This method also accepts an array of item keys to unset::
-
-	$array_items = array('username', 'email');
-
-	$this->session->unset_userdata($array_items);
-
-.. note:: In previous versions, the ``unset_userdata()`` method used
-	to accept an associative array of ``key => 'dummy value'``
-	pairs. This is no longer supported.
-
-Flashdata
-=========
-
-CodeIgniter supports "flashdata", or session data that will only be
-available for the next request, and is then automatically cleared.
-
-This can be very useful, especially for one-time informational, error or
-status messages (for example: "Record 2 deleted").
-
-It should be noted that flashdata variables are regular session vars,
-only marked in a specific way under the '__ci_vars' key (please don't touch
-that one, you've been warned).
-
-To mark an existing item as "flashdata"::
-
-	$this->session->mark_as_flash('item');
-
-If you want to mark multiple items as flashdata, simply pass the keys as an
-array::
-
-	$this->session->mark_as_flash(array('item', 'item2'));
-
-To add flashdata::
-
-	$_SESSION['item'] = 'value';
-	$this->session->mark_as_flash('item');
-
-Or alternatively, using the ``set_flashdata()`` method::
-
-	$this->session->set_flashdata('item', 'value');
-
-You can also pass an array to ``set_flashdata()``, in the same manner as
-``set_userdata()``.
-
-Reading flashdata variables is the same as reading regular session data
-through ``$_SESSION``::
-
-	$_SESSION['item']
-
-.. important:: The ``userdata()`` method will NOT return flashdata items.
-
-However, if you want to be sure that you're reading "flashdata" (and not
-any other kind), you can also use the ``flashdata()`` method::
-
-	$this->session->flashdata('item');
-
-Or to get an array with all flashdata, simply omit the key parameter::
-
-	$this->session->flashdata();
-
-.. note:: The ``flashdata()`` method returns NULL if the item cannot be
-	found.
-
-If you find that you need to preserve a flashdata variable through an
-additional request, you can do so using the ``keep_flashdata()`` method.
-You can either pass a single item or an array of flashdata items to keep.
-
-::
-
-	$this->session->keep_flashdata('item');
-	$this->session->keep_flashdata(array('item1', 'item2', 'item3'));
-
-Tempdata
-========
-
-CodeIgniter also supports "tempdata", or session data with a specific
-expiration time. After the value expires, or the session expires or is
-deleted, the value is automatically removed.
-
-Similarly to flashdata, tempdata variables are regular session vars that
-are marked in a specific way under the '__ci_vars' key (again, don't touch
-that one).
-
-To mark an existing item as "tempdata", simply pass its key and expiry time
-(in seconds!) to the ``mark_as_temp()`` method::
-
-	// 'item' will be erased after 300 seconds
-	$this->session->mark_as_temp('item', 300);
-
-You can mark multiple items as tempdata in two ways, depending on whether
-you want them all to have the same expiry time or not::
-
-	// Both 'item' and 'item2' will expire after 300 seconds
-	$this->session->mark_as_temp(array('item', 'item2'), 300);
-
-	// 'item' will be erased after 300 seconds, while 'item2'
-	// will do so after only 240 seconds
-	$this->session->mark_as_temp(array(
-		'item'	=> 300,
-		'item2'	=> 240
-	));
-
-To add tempdata::
-
-	$_SESSION['item'] = 'value';
-	$this->session->mark_as_temp('item', 300); // Expire in 5 minutes
-
-Or alternatively, using the ``set_tempdata()`` method::
-
-	$this->session->set_tempdata('item', 'value', 300);
-
-You can also pass an array to ``set_tempdata()``::
-
-	$tempdata = array('newuser' => TRUE, 'message' => 'Thanks for joining!');
-
-	$this->session->set_tempdata($tempdata, NULL, $expire);
-
-.. note:: If the expiration is omitted or set to 0, the default
-	time-to-live value of 300 seconds (or 5 minutes) will be used.
-
-To read a tempdata variable, again you can just access it through the
-``$_SESSION`` superglobal array::
-
-	$_SESSION['item']
-
-.. important:: The ``userdata()`` method will NOT return tempdata items.
-
-Or if you want to be sure that you're reading "tempdata" (and not any
-other kind), you can also use the ``tempdata()`` method::
-
-	$this->session->tempdata('item');
-
-And of course, if you want to retrieve all existing tempdata::
-
-	$this->session->tempdata();
-
-.. note:: The ``tempdata()`` method returns NULL if the item cannot be
-	found.
-
-If you need to remove a tempdata value before it expires, you can directly
-unset it from the ``$_SESSION`` array::
-
-	unset($_SESSION['item']);
-
-However, this won't remove the marker that makes this specific item to be
-tempdata (it will be invalidated on the next HTTP request), so if you
-intend to reuse that same key in the same request, you'd want to use
-``unset_tempdata()``::
-
-	$this->session->unset_tempdata('item');
-
-Destroying a Session
-====================
-
-To clear the current session (for example, during a logout), you may
-simply use either PHP's `session_destroy() <http://php.net/session_destroy>`_
-function, or the ``sess_destroy()`` method. Both will work in exactly the
-same way::
-
-	session_destroy();
-
-	// or
-
-	$this->session->sess_destroy();
-
-.. note:: This must be the last session-related operation that you do
-	during the same request. All session data (including flashdata and
-	tempdata) will be destroyed permanently and functions will be
-	unusable during the same request after you destroy the session.
-
-Accessing session metadata
-==========================
-
-In previous CodeIgniter versions, the session data array included 4 items
-by default: 'session_id', 'ip_address', 'user_agent', 'last_activity'.
-
-This was due to the specifics of how sessions worked, but is now no longer
-necessary with our new implementation. However, it may happen that your
-application relied on these values, so here are alternative methods of
-accessing them:
-
-  - session_id: ``session_id()``
-  - ip_address: ``$_SERVER['REMOTE_ADDR']``
-  - user_agent: ``$this->input->user_agent()`` (unused by sessions)
-  - last_activity: Depends on the storage, no straightforward way. Sorry!
-
-Session Preferences
-===================
-
-CodeIgniter will usually make everything work out of the box. However,
-Sessions are a very sensitive component of any application, so some
-careful configuration must be done. Please take your time to consider
-all of the options and their effects.
-
-You'll find the following Session related preferences in your
-**application/config/config.php** file:
-
-============================ =============== ======================================== ============================================================================================
-Preference                   Default         Options                                  Description
-============================ =============== ======================================== ============================================================================================
-**sess_driver**              files           files/database/redis/memcached/*custom*  The session storage driver to use.
-**sess_cookie_name**         ci_session      [A-Za-z\_-] characters only              The name used for the session cookie.
-**sess_expiration**          7200 (2 hours)  Time in seconds (integer)                The number of seconds you would like the session to last.
-                                                                                      If you would like a non-expiring session (until browser is closed) set the value to zero: 0
-**sess_save_path**           NULL            None                                     Specifies the storage location, depends on the driver being used.
-**sess_match_ip**            FALSE           TRUE/FALSE (boolean)                     Whether to validate the user's IP address when reading the session cookie.
-                                                                                      Note that some ISPs dynamically changes the IP, so if you want a non-expiring session you
-                                                                                      will likely set this to FALSE.
-**sess_time_to_update**      300             Time in seconds (integer)                This option controls how often the session class will regenerate itself and create a new
-                                                                                      session ID. Setting it to 0 will disable session ID regeneration.
-**sess_regenerate_destroy**  FALSE           TRUE/FALSE (boolean)                     Whether to destroy session data associated with the old session ID when auto-regenerating
-                                                                                      the session ID. When set to FALSE, the data will be later deleted by the garbage collector.
-============================ =============== ======================================== ============================================================================================
-
-.. note:: As a last resort, the Session library will try to fetch PHP's
-	session related INI settings, as well as legacy CI settings such as
-	'sess_expire_on_close' when any of the above is not configured.
-	However, you should never rely on this behavior as it can cause
-	unexpected results or be changed in the future. Please configure
-	everything properly.
-
-In addition to the values above, the cookie and native drivers apply the
-following configuration values shared by the :doc:`Input <input>` and
-:doc:`Security <security>` classes:
-
-================== =============== ===========================================================================
-Preference         Default         Description
-================== =============== ===========================================================================
-**cookie_domain**  ''              The domain for which the session is applicable
-**cookie_path**    /               The path to which the session is applicable
-**cookie_secure**  FALSE           Whether to create the session cookie only on encrypted (HTTPS) connections
-================== =============== ===========================================================================
-
-.. note:: The 'cookie_httponly' setting doesn't have an effect on sessions.
-	Instead the HttpOnly parameter is always enabled, for security
-	reasons. Additionally, the 'cookie_prefix' setting is completely
-	ignored.
-
-Session Drivers
-===============
-
-As already mentioned, the Session library comes with 4 drivers, or storage
-engines, that you can use:
-
-  - files
-  - database
-  - redis
-  - memcached
-
-By default, the `Files Driver`_ will be used when a session is initialized,
-because it is the most safe choice and is expected to work everywhere
-(virtually every environment has a file system).
-
-However, any other driver may be selected via the ``$config['sess_driver']``
-line in your **application/config/config.php** file, if you chose to do so.
-Have it in mind though, every driver has different caveats, so be sure to
-get yourself familiar with them (below) before you make that choice.
-
-In addition, you may also create and use `Custom Drivers`_, if the ones
-provided by default don't satisfy your use case.
-
-.. note:: In previous CodeIgniter versions, a different, "cookie driver"
-	was the only option and we have received negative feedback on not
-	providing that option. While we do listen to feedback from the
-	community, we want to warn you that it was dropped because it is
-	**unsafe** and we advise you NOT to try to replicate it via a
-	custom driver.
-
-Files Driver
-------------
-
-The 'files' driver uses your file system for storing session data.
-
-It can safely be said that it works exactly like PHP's own default session
-implementation, but in case this is an important detail for you, have it
-mind that it is in fact not the same code and it has some limitations
-(and advantages).
-
-To be more specific, it doesn't support PHP's `directory level and mode
-formats used in session.save_path
-<http://php.net/manual/en/session.configuration.php#ini.session.save-path>`_,
-and it has most of the options hard-coded for safety. Instead, only
-absolute paths are supported for ``$config['sess_save_path']``.
-
-Another important thing that you should know, is to make sure that you
-don't use a publicly-readable or shared directory for storing your session
-files. Make sure that *only you* have access to see the contents of your
-chosen *sess_save_path* directory. Otherwise, anybody who can do that, can
-also steal any of the current sessions (also known as "session fixation"
-attack).
-
-On UNIX-like operating systems, this is usually achieved by setting the
-0700 mode permissions on that directory via the `chmod` command, which
-allows only the directory's owner to perform read and write operations on
-it. But be careful because the system user *running* the script is usually
-not your own, but something like 'www-data' instead, so only setting those
-permissions will probable break your application.
-
-Instead, you should do something like this, depending on your environment
-::
-
-	mkdir /<path to your application directory>/sessions/
-	chmod 0700 /<path to your application directory>/sessions/
-	chown www-data /<path to your application directory>/sessions/
-
-Bonus Tip
-^^^^^^^^^
-
-Some of you will probably opt to choose another session driver because
-file storage is usually slower. This is only half true.
-
-A very basic test will probably trick you into believing that an SQL
-database is faster, but in 99% of the cases, this is only true while you
-only have a few current sessions. As the sessions count and server loads
-increase - which is the time when it matters - the file system will
-consistently outperform almost all relational database setups.
-
-In addition, if performance is your only concern, you may want to look
-into using `tmpfs <http://eddmann.com/posts/storing-php-sessions-file-caches-in-memory-using-tmpfs/>`_,
-(warning: external resource), which can make your sessions blazing fast.
-
-Database Driver
----------------
-
-The 'database' driver uses a relational database such as MySQL or
-PostgreSQL to store sessions. This is a popular choice among many users,
-because it allows the developer easy access to the session data within
-an application - it is just another table in your database.
-
-However, there are some conditions that must be met:
-
-  - Only your **default** database connection (or the one that you access
-    as ``$this->db`` from your controllers) can be used.
-  - You must have the :doc:`Query Builder </database/query_builder>`
-    enabled.
-  - You can NOT use a persistent connection.
-  - You can NOT use a connection with the *cache_on* setting enabled.
-
-In order to use the 'database' session driver, you must also create this
-table that we already mentioned and then set it as your
-``$config['sess_save_path']`` value.
-For example, if you would like to use 'ci_sessions' as your table name,
-you would do this::
-
-	$config['sess_driver'] = 'database';
-	$config['sess_save_path'] = 'ci_sessions';
-
-.. note:: If you've upgraded from a previous version of CodeIgniter and
-	you don't have 'sess_save_path' configured, then the Session
-	library will look for the old 'sess_table_name' setting and use
-	it instead. Please don't rely on this behavior as it will get
-	removed in the future.
-
-And then of course, create the database table ...
-
-For MySQL::
-
-	CREATE TABLE IF NOT EXISTS `ci_sessions` (
-		`id` varchar(128) NOT NULL,
-		`ip_address` varchar(45) NOT NULL,
-		`timestamp` int(10) unsigned DEFAULT 0 NOT NULL,
-		`data` blob NOT NULL,
-		KEY `ci_sessions_timestamp` (`timestamp`)
-	);
-
-For PostgreSQL::
-
-	CREATE TABLE "ci_sessions" (
-		"id" varchar(128) NOT NULL,
-		"ip_address" varchar(45) NOT NULL,
-		"timestamp" bigint DEFAULT 0 NOT NULL,
-		"data" text DEFAULT '' NOT NULL
-	);
-
-	CREATE INDEX "ci_sessions_timestamp" ON "ci_sessions" ("timestamp");
-
-You will also need to add a PRIMARY KEY **depending on your 'sess_match_ip'
-setting**. The examples below work both on MySQL and PostgreSQL::
-
-	// When sess_match_ip = TRUE
-	ALTER TABLE ci_sessions ADD PRIMARY KEY (id, ip_address);
-
-	// When sess_match_ip = FALSE
-	ALTER TABLE ci_sessions ADD PRIMARY KEY (id);
-
-	// To drop a previously created primary key (use when changing the setting)
-	ALTER TABLE ci_sessions DROP PRIMARY KEY;
-
-
-.. important:: Only MySQL and PostgreSQL databases are officially
-	supported, due to lack of advisory locking mechanisms on other
-	platforms. Using sessions without locks can cause all sorts of
-	problems, especially with heavy usage of AJAX, and we will not
-	support such cases. Use ``session_write_close()`` after you've
-	done processing session data if you're having performance
-	issues.
-
-Redis Driver
-------------
-
-.. note:: Since Redis doesn't have a locking mechanism exposed, locks for
-	this driver are emulated by a separate value that is kept for up
-	to 300 seconds.
-
-Redis is a storage engine typically used for caching and popular because
-of its high performance, which is also probably your reason to use the
-'redis' session driver.
-
-The downside is that it is not as ubiquitous as relational databases and
-requires the `phpredis <https://github.com/phpredis/phpredis>`_ PHP
-extension to be installed on your system, and that one doesn't come
-bundled with PHP.
-Chances are, you're only be using the 'redis' driver only if you're already
-both familiar with Redis and using it for other purposes.
-
-Just as with the 'files' and 'database' drivers, you must also configure
-the storage location for your sessions via the
-``$config['sess_save_path']`` setting.
-The format here is a bit different and complicated at the same time. It is
-best explained by the *phpredis* extension's README file, so we'll simply
-link you to it:
-
-	https://github.com/phpredis/phpredis#php-session-handler
-
-.. warning:: CodeIgniter's Session library does NOT use the actual 'redis'
-	``session.save_handler``. Take note **only** of the path format in
-	the link above.
-
-For the most common case however, a simple ``host:port`` pair should be
-sufficient::
-
-	$config['sess_driver'] = 'redis';
-	$config['sess_save_path'] = 'tcp://localhost:6379';
-
-Memcached Driver
-----------------
-
-.. note:: Since Memcache doesn't have a locking mechanism exposed, locks
-	for this driver are emulated by a separate value that is kept for
-	up to 300 seconds.
-
-The 'memcached' driver is very similar to the 'redis' one in all of its
-properties, except perhaps for availability, because PHP's `Memcached
-<http://php.net/memcached>`_ extension is distributed via PECL and some
-Linux distrubutions make it available as an easy to install package.
-
-Other than that, and without any intentional bias towards Redis, there's
-not much different to be said about Memcached - it is also a popular
-product that is usually used for caching and famed for its speed.
-
-However, it is worth noting that the only guarantee given by Memcached
-is that setting value X to expire after Y seconds will result in it being
-deleted after Y seconds have passed (but not necessarily that it won't
-expire earlier than that time). This happens very rarely, but should be
-considered as it may result in loss of sessions.
-
-The ``$config['sess_save_path']`` format is fairly straightforward here,
-being just a ``host:port`` pair::
-
-	$config['sess_driver'] = 'memcached';
-	$config['sess_save_path'] = 'localhost:11211';
-
-Bonus Tip
-^^^^^^^^^
-
-Multi-server configuration with an optional *weight* parameter as the
-third colon-separated (``:weight``) value is also supported, but we have
-to note that we haven't tested if that is reliable.
-
-If you want to experiment with this feature (on your own risk), simply
-separate the multiple server paths with commas::
-
-	// localhost will be given higher priority (5) here,
-	// compared to 192.0.2.1 with a weight of 1.
-	$config['sess_save_path'] = 'localhost:11211:5,192.0.2.1:11211:1';
-
-Custom Drivers
---------------
-
-You may also create your own, custom session drivers. However, have it in
-mind that this is typically not an easy task, as it takes a lot of
-knowledge to do it properly.
-
-You need to know not only how sessions work in general, but also how they
-work specifically in PHP, how the underlying storage mechanism works, how
-to handle concurrency, avoid deadlocks (but NOT through lack of locks) and
-last but not least - how to handle the potential security issues, which
-is far from trivial.
-
-Long story short - if you don't know how to do that already in raw PHP,
-you shouldn't be trying to do it within CodeIgniter either. You've been
-warned.
-
-If you only want to add some extra functionality to your sessions, just
-extend the base Session class, which is a lot more easier. Read the
-:doc:`Creating Libraries <../general/creating_libraries>` article to
-learn how to do that.
-
-Now, to the point - there are three general rules that you must follow
-when creating a session driver for CodeIgniter:
-
-  - Put your driver's file under **application/libraries/Session/drivers/**
-    and follow the naming conventions used by the Session class.
-
-    For example, if you were to create a 'dummy' driver, you would have
-    a ``Session_dummy_driver`` class name, that is declared in
-    *application/libraries/Session/drivers/Session_dummy_driver.php*.
-
-  - Extend the ``CI_Session_driver`` class.
-
-    This is just a basic class with a few internal helper methods. It is
-    also extendable like any other library, if you really need to do that,
-    but we are not going to explain how ... if you're familiar with how
-    class extensions/overrides work in CI, then you already know how to do
-    it. If not, well, you shouldn't be doing it in the first place.
-
-
-  - Implement the `SessionHandlerInterface
-    <http://php.net/sessionhandlerinterface>`_ interface.
-
-    .. note:: You may notice that ``SessionHandlerInterface`` is provided
-    	by PHP since version 5.4.0. CodeIgniter will automatically declare
-    	the same interface if you're running an older PHP version.
-
-    The link will explain why and how.
-
-So, based on our 'dummy' driver example above, you'd end up with something
-like this::
-
-	// application/libraries/Session/drivers/Session_dummy_driver.php:
-
-	class CI_Session_dummy_driver extends CI_Session_driver implements SessionHandlerInterface
-	{
-
-		public function __construct(&$params)
-		{
-			// DO NOT forget this
-			parent::__construct($params);
-
-			// Configuration & other initializations
-		}
-
-		public function open($save_path, $name)
-		{
-			// Initialize storage mechanism (connection)
-		}
-
-		public function read($session_id)
-		{
-			// Read session data (if exists), acquire locks
-		}
-
-		public function write($session_id, $session_data)
-		{
-			// Create / update session data (it might not exist!)
-		}
-
-		public function close()
-		{
-			// Free locks, close connections / streams / etc.
-		}
-
-		public function destroy($session_id)
-		{
-			// Call close() method & destroy data for current session (order may differ)
-		}
-
-		public function gc($maxlifetime)
-		{
-			// Erase data for expired sessions
-		}
-
-	}
-
-If you've done everything properly, you can now set your *sess_driver*
-configuration value to 'dummy' and use your own driver. Congratulations!

-HTML Table Class
-################
-
-The Table Class provides functions that enable you to auto-generate HTML
-tables from arrays or database result sets.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-*********************
-Using the Table Class
-*********************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Table class is initialized
-in your controller using the ``$this->load->library()`` method::
-
-	$this->load->library('table');
-
-Once loaded, the Table library object will be available using::
-
-	$this->table
-
-Examples
-========
-
-Here is an example showing how you can create a table from a
-multi-dimensional array. Note that the first array index will become the
-table heading (or you can set your own headings using the ``set_heading()``
-method described in the function reference below).
-
-::
-
-	$this->load->library('table');
-
-	$data = array(
-		array('Name', 'Color', 'Size'),
-		array('Fred', 'Blue', 'Small'),
-		array('Mary', 'Red', 'Large'),
-		array('John', 'Green', 'Medium')	
-	);
-
-	echo $this->table->generate($data);
-
-Here is an example of a table created from a database query result. The
-table class will automatically generate the headings based on the table
-names (or you can set your own headings using the ``set_heading()``
-method described in the class reference below).
-
-::
-
-	$this->load->library('table');
-
-	$query = $this->db->query('SELECT * FROM my_table');
-
-	echo $this->table->generate($query);
-
-Here is an example showing how you might create a table using discrete
-parameters::
-
-	$this->load->library('table');
-
-	$this->table->set_heading('Name', 'Color', 'Size');
-
-	$this->table->add_row('Fred', 'Blue', 'Small');
-	$this->table->add_row('Mary', 'Red', 'Large');
-	$this->table->add_row('John', 'Green', 'Medium');
-
-	echo $this->table->generate();
-
-Here is the same example, except instead of individual parameters,
-arrays are used::
-
-	$this->load->library('table');
-
-	$this->table->set_heading(array('Name', 'Color', 'Size'));
-
-	$this->table->add_row(array('Fred', 'Blue', 'Small'));
-	$this->table->add_row(array('Mary', 'Red', 'Large'));
-	$this->table->add_row(array('John', 'Green', 'Medium'));
-
-	echo $this->table->generate();
-
-Changing the Look of Your Table
-===============================
-
-The Table Class permits you to set a table template with which you can
-specify the design of your layout. Here is the template prototype::
-
-	$template = array(
-		'table_open'		=> '<table border="0" cellpadding="4" cellspacing="0">',
-
-		'thead_open'		=> '<thead>',
-		'thead_close'		=> '</thead>',
-
-		'heading_row_start'	=> '<tr>',
-		'heading_row_end'	=> '</tr>',
-		'heading_cell_start'	=> '<th>',
-		'heading_cell_end'	=> '</th>',
-
-		'tbody_open'		=> '<tbody>',
-		'tbody_close'		=> '</tbody>',
-
-		'row_start'		=> '<tr>',
-		'row_end'		=> '</tr>',
-		'cell_start'		=> '<td>',
-		'cell_end'		=> '</td>',
-
-		'row_alt_start'		=> '<tr>',
-		'row_alt_end'		=> '</tr>',
-		'cell_alt_start'	=> '<td>',
-		'cell_alt_end'		=> '</td>',
-
-		'table_close'		=> '</table>'
-	);
-
-	$this->table->set_template($template);
-
-.. note:: You'll notice there are two sets of "row" blocks in the
-	template. These permit you to create alternating row colors or design
-	elements that alternate with each iteration of the row data.
-
-You are NOT required to submit a complete template. If you only need to
-change parts of the layout you can simply submit those elements. In this
-example, only the table opening tag is being changed::
-
-	$template = array(
-		'table_open' => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">'
-	);
-
-	$this->table->set_template($template);
-	
-You can also set defaults for these in a config file.
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_Table
-
-	.. attribute:: $function = NULL
-
-		Allows you to specify a native PHP function or a valid function array object to be applied to all cell data.
-		::
-
-			$this->load->library('table');
-
-			$this->table->set_heading('Name', 'Color', 'Size');
-			$this->table->add_row('Fred', '<strong>Blue</strong>', 'Small');
-
-			$this->table->function = 'htmlspecialchars';
-			echo $this->table->generate();
-
-		In the above example, all cell data would be ran through PHP's :php:func:`htmlspecialchars()` function, resulting in::
-
-			<td>Fred</td><td>&lt;strong&gt;Blue&lt;/strong&gt;</td><td>Small</td>
-
-	.. php:method:: generate([$table_data = NULL])
-
-		:param	mixed	$table_data: Data to populate the table rows with
-		:returns:	HTML table
-		:rtype:	string
-
-		Returns a string containing the generated table. Accepts an optional parameter which can be an array or a database result object.
-
-	.. php:method:: set_caption($caption)
-
-		:param	string	$caption: Table caption
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Permits you to add a caption to the table.
-		::
-
-			$this->table->set_caption('Colors');
-
-	.. php:method:: set_heading([$args = array()[, ...]])
-
-		:param	mixed	$args: An array or multiple strings containing the table column titles
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Permits you to set the table heading. You can submit an array or discrete params::
-
-			$this->table->set_heading('Name', 'Color', 'Size');
-
-			$this->table->set_heading(array('Name', 'Color', 'Size'));
-
-	.. php:method:: add_row([$args = array()[, ...]])
-
-		:param	mixed	$args: An array or multiple strings containing the row values
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Permits you to add a row to your table. You can submit an array or discrete params::
-
-			$this->table->add_row('Blue', 'Red', 'Green');
-
-			$this->table->add_row(array('Blue', 'Red', 'Green'));
-
-		If you would like to set an individual cell's tag attributes, you can use an associative array for that cell.
-		The associative key **data** defines the cell's data. Any other key => val pairs are added as key='val' attributes to the tag::
-
-			$cell = array('data' => 'Blue', 'class' => 'highlight', 'colspan' => 2);
-			$this->table->add_row($cell, 'Red', 'Green');
-
-			// generates

-
-		:param	array	$array: An array containing multiple rows' data
-		:param	int	$col_limit: Count of columns in the table
-		:returns:	An array of HTML table columns
-		:rtype:	array
-
-		This method takes a one-dimensional array as input and creates a multi-dimensional array with a depth equal to the number of columns desired.
-		This allows a single array with many elements to be displayed in a table that has a fixed column count. Consider this example::
-
-			$list = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve');
-
-			$new_list = $this->table->make_columns($list, 3);
-
-			$this->table->generate($new_list);
-
-			// Generates a table with this prototype
-
-			<table border="0" cellpadding="4" cellspacing="0">
-			<tr>
-			<td>one</td><td>two</td><td>three</td>
-			</tr><tr>
-			<td>four</td><td>five</td><td>six</td>
-			</tr><tr>

-			<td>ten</td><td>eleven</td><td>twelve</td></tr>
-			</table>
-
-
-	.. php:method:: set_template($template)
-
-		:param	array	$template: An associative array containing template values
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		Permits you to set your template. You can submit a full or partial template.
-		::
-
-			$template = array(
-				'table_open'  => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">'
-			);
-		
-			$this->table->set_template($template);
-
-	.. php:method:: set_empty($value)
-
-		:param	mixed	$value: Value to put in empty cells
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Lets you set a default value for use in any table cells that are empty.
-		You might, for example, set a non-breaking space::
-
-			$this->table->set_empty("&nbsp;");
-
-	.. php:method:: clear()
-
-		:returns:	CI_Table instance (method chaining)
-		:rtype:	CI_Table
-
-		Lets you clear the table heading and row data. If you need to show multiple tables with different data you should to call this method
-		after each table has been generated to clear the previous table information. Example::
-
-			$this->load->library('table');
-
-			$this->table->set_heading('Name', 'Color', 'Size');
-			$this->table->add_row('Fred', 'Blue', 'Small');
-			$this->table->add_row('Mary', 'Red', 'Large');
-			$this->table->add_row('John', 'Green', 'Medium');
-
-			echo $this->table->generate();
-
-			$this->table->clear();
-
-			$this->table->set_heading('Name', 'Day', 'Delivery');
-			$this->table->add_row('Fred', 'Wednesday', 'Express');
-			$this->table->add_row('Mary', 'Monday', 'Air');

-Trackback Class
-###############
-
-The Trackback Class provides functions that enable you to send and
-receive Trackback data.
-
-If you are not familiar with Trackbacks you'll find more information
-`here <http://en.wikipedia.org/wiki/Trackback>`_.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-*************************
-Using the Trackback Class
-*************************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Trackback class is
-initialized in your controller using the ``$this->load->library()`` method::
-
-	$this->load->library('trackback');
-
-Once loaded, the Trackback library object will be available using::
-
-	$this->trackback
-
-Sending Trackbacks
-==================
-
-A Trackback can be sent from any of your controller functions using code
-similar to this example::
-
-	$this->load->library('trackback');
-
-	$tb_data = array(
-		'ping_url'  => 'http://example.com/trackback/456',
-		'url'       => 'http://www.my-example.com/blog/entry/123',
-		'title'     => 'The Title of My Entry',
-		'excerpt'   => 'The entry content.',
-		'blog_name' => 'My Blog Name',
-		'charset'   => 'utf-8'
-	);
-
-	if ( ! $this->trackback->send($tb_data))
-	{
-		echo $this->trackback->display_errors();
-	}
-	else
-	{
-		echo 'Trackback was sent!';
-	}
-
-Description of array data:
-
--  **ping_url** - The URL of the site you are sending the Trackback to.
-   You can send Trackbacks to multiple URLs by separating each URL with a comma.
--  **url** - The URL to YOUR site where the weblog entry can be seen.
--  **title** - The title of your weblog entry.
--  **excerpt** - The content of your weblog entry.
--  **blog_name** - The name of your weblog.
--  **charset** - The character encoding your weblog is written in. If omitted, UTF-8 will be used.
-
-.. note:: The Trackback class will automatically send only the first 500 characters of your 
-	entry. It will also strip all HTML.
-
-The Trackback sending method returns TRUE/FALSE (boolean) on success
-or failure. If it fails, you can retrieve the error message using::
-
-	$this->trackback->display_errors();
-
-Receiving Trackbacks
-====================
-
-Before you can receive Trackbacks you must create a weblog. If you don't
-have a blog yet there's no point in continuing.
-
-Receiving Trackbacks is a little more complex than sending them, only
-because you will need a database table in which to store them, and you
-will need to validate the incoming trackback data. You are encouraged to
-implement a thorough validation process to guard against spam and
-duplicate data. You may also want to limit the number of Trackbacks you
-allow from a particular IP within a given span of time to further
-curtail spam. The process of receiving a Trackback is quite simple; the
-validation is what takes most of the effort.
-
-Your Ping URL
-=============
-
-In order to accept Trackbacks you must display a Trackback URL next to
-each one of your weblog entries. This will be the URL that people will
-use to send you Trackbacks (we will refer to this as your "Ping URL").
-
-Your Ping URL must point to a controller function where your Trackback
-receiving code is located, and the URL must contain the ID number for
-each particular entry, so that when the Trackback is received you'll be
-able to associate it with a particular entry.
-
-For example, if your controller class is called Trackback, and the
-receiving function is called receive, your Ping URLs will look something
-like this::
-
-	http://example.com/index.php/trackback/receive/entry_id
-
-Where entry_id represents the individual ID number for each of your
-entries.
-
-Creating a Trackback Table
-==========================
-
-Before you can receive Trackbacks you must create a table in which to
-store them. Here is a basic prototype for such a table::
-
-	CREATE TABLE trackbacks (
-		tb_id int(10) unsigned NOT NULL auto_increment,
-		entry_id int(10) unsigned NOT NULL default 0,
-		url varchar(200) NOT NULL,
-		title varchar(100) NOT NULL,
-		excerpt text NOT NULL,
-		blog_name varchar(100) NOT NULL,
-		tb_date int(10) NOT NULL,
-		ip_address varchar(45) NOT NULL,
-		PRIMARY KEY `tb_id` (`tb_id`),
-		KEY `entry_id` (`entry_id`)
-	);
-
-The Trackback specification only requires four pieces of information to
-be sent in a Trackback (url, title, excerpt, blog_name), but to make
-the data more useful we've added a few more fields in the above table
-schema (date, IP address, etc.).
-
-Processing a Trackback
-======================
-
-Here is an example showing how you will receive and process a Trackback.
-The following code is intended for use within the controller function
-where you expect to receive Trackbacks.::
-
-	$this->load->library('trackback');
-	$this->load->database();
-
-	if ($this->uri->segment(3) == FALSE)
-	{
-		$this->trackback->send_error('Unable to determine the entry ID');
-	}
-
-	if ( ! $this->trackback->receive())
-	{
-		$this->trackback->send_error('The Trackback did not contain valid data');
-	}
-
-	$data = array(
-		'tb_id'      => '',
-		'entry_id'   => $this->uri->segment(3),
-		'url'        => $this->trackback->data('url'),
-		'title'      => $this->trackback->data('title'),
-		'excerpt'    => $this->trackback->data('excerpt'),
-		'blog_name'  => $this->trackback->data('blog_name'),
-		'tb_date'    => time(),
-		'ip_address' => $this->input->ip_address()
-	);
-
-	$sql = $this->db->insert_string('trackbacks', $data);
-	$this->db->query($sql);
-
-	$this->trackback->send_success();
-
-Notes:
-^^^^^^
-
-The entry ID number is expected in the third segment of your URL. This
-is based on the URI example we gave earlier::

-	http://example.com/index.php/trackback/receive/entry_id
-
-Notice the entry_id is in the third URI segment, which you can retrieve
-using::
-
-	$this->uri->segment(3);
-
-In our Trackback receiving code above, if the third segment is missing,
-we will issue an error. Without a valid entry ID, there's no reason to
-continue.
-
-The $this->trackback->receive() function is simply a validation function
-that looks at the incoming data and makes sure it contains the four
-pieces of data that are required (url, title, excerpt, blog_name). It
-returns TRUE on success and FALSE on failure. If it fails you will issue
-an error message.
-
-The incoming Trackback data can be retrieved using this function::
-
-	$this->trackback->data('item')
-
-Where item represents one of these four pieces of info: url, title,
-excerpt, or blog_name
-
-If the Trackback data is successfully received, you will issue a success
-message using::
-
-	$this->trackback->send_success();
-
-.. note:: The above code contains no data validation, which you are
-	encouraged to add.

-**************************
-Using the Typography Class
-**************************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Typography class is
-initialized in your controller using the ``$this->load->library()`` method::
-
-	$this->load->library('typography');
-
-Once loaded, the Typography library object will be available using::
-
-	$this->typography
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_Typography
-
-	.. attribute:: $protect_braced_quotes = FALSE
-
-		When using the Typography library in conjunction with the :doc:`Template Parser library <parser>`
-		it can often be desirable to protect single and double quotes within curly braces.
-		To enable this, set the ``protect_braced_quotes`` class property to TRUE.
-
-		Usage example::
-
-			$this->load->library('typography');
-			$this->typography->protect_braced_quotes = TRUE;
-
-	.. php:method:: auto_typography($str[, $reduce_linebreaks = FALSE])
-
-		:param	string	$str: Input string
-		:param	bool	$reduce_linebreaks: Whether to reduce consequitive linebreaks
-		:returns:	HTML typography-safe string
-		:rtype:	string
-
-		Formats text so that it is semantically and typographically correct HTML.
-		Takes a string as input and returns it with the following formatting:
-
-		 -  Surrounds paragraphs within <p></p> (looks for double line breaks to identify paragraphs).
-		 -  Single line breaks are converted to <br />, except those that appear within <pre> tags.
-		 -  Block level elements, like <div> tags, are not wrapped within paragraphs, but their contained text is if it contains paragraphs.
-		 -  Quotes are converted to correctly facing curly quote entities, except those that appear within tags.
-		 -  Apostrophes are converted to curly apostrophe entities.
-		 -  Double dashes (either like -- this or like--this) are converted to em—dashes.
-		 -  Three consecutive periods either preceding or following a word are converted to ellipsis (…).
-		 -  Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.
-
-		Usage example::
-
-			$string = $this->typography->auto_typography($string);
-
-		There is one optional parameter that determines whether the parser should reduce more than two consecutive line breaks down to two.
-		Pass boolean TRUE to enable reducing line breaks::
-
-			$string = $this->typography->auto_typography($string, TRUE);
-
-		.. note:: Typographic formatting can be processor intensive, particularly if you have a lot of content being formatted.
-			If you choose to use this method you may want to consider :doc:`caching <../general/caching>` your pages.
-
-	.. php:method:: format_characters($str)
-
-		:param	string	$str: Input string
-		:returns:	Formatted string
-		:rtype:	string
-
-		This method is similar to ``auto_typography()`` above, except that it only does character conversion:
-
-		 -  Quotes are converted to correctly facing curly quote entities, except those that appear within tags.
-		 -  Apostrophes are converted to curly apostrophe entities.
-		 -  Double dashes (either like -- this or like--this) are converted to em—dashes.
-		 -  Three consecutive periods either preceding or following a word are converted to ellipsis (…).
-		 -  Double spaces following sentences are converted to non-breaking spaces to mimic double spacing.
-
-		Usage example::
-
-			$string = $this->typography->format_characters($string);
-
-	.. php:method:: nl2br_except_pre($str)
-
-		:param	string	$str: Input string
-		:returns:	Formatted string
-		:rtype:	string
-
-		Converts newlines to <br /> tags unless they appear within <pre> tags.
-		This method is identical to the native PHP :php:func:`nl2br()` function, except that it ignores <pre> tags.
-
-		Usage example::
-
-			$string = $this->typography->nl2br_except_pre($string);

-##################
-Unit Testing Class
-##################
-
-Unit testing is an approach to software development in which tests are
-written for each function in your application. If you are not familiar
-with the concept you might do a little googling on the subject.
-
-CodeIgniter's Unit Test class is quite simple, consisting of an
-evaluation function and two result functions. It's not intended to be a
-full-blown test suite but rather a simple mechanism to evaluate your
-code to determine if it is producing the correct data type and result.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-******************************
-Using the Unit Testing Library
-******************************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Unit Test class is
-initialized in your controller using the $this->load->library function::
-
-	$this->load->library('unit_test');
-
-Once loaded, the Unit Test object will be available using ``$this->unit``
-
-Running Tests
-=============
-
-Running a test involves supplying a test and an expected result in the
-following way:
-
-	$this->unit->run('test', 'expected result', 'test name', 'notes');
-
-Where test is the result of the code you wish to test, expected result
-is the data type you expect, test name is an optional name you can give
-your test, and notes are optional notes. Example::
-
-	$test = 1 + 1;
-
-	$expected_result = 2;
-
-	$test_name = 'Adds one plus one';
-
-	$this->unit->run($test, $expected_result, $test_name);
-
-The expected result you supply can either be a literal match, or a data
-type match. Here's an example of a literal::
-
-	$this->unit->run('Foo', 'Foo');
-
-Here is an example of a data type match::
-
-	$this->unit->run('Foo', 'is_string');
-
-Notice the use of "is_string" in the second parameter? This tells the
-function to evaluate whether your test is producing a string as the
-result. Here is a list of allowed comparison types:
-
--  is_object
--  is_string
--  is_bool
--  is_true
--  is_false
--  is_int
--  is_numeric
--  is_float
--  is_double
--  is_array
--  is_null
--  is_resource
-
-Generating Reports
-==================
-
-You can either display results after each test, or your can run several
-tests and generate a report at the end. To show a report directly simply
-echo or return the run function::
-
-	echo $this->unit->run($test, $expected_result);
-
-To run a full report of all tests, use this::
-
-	echo $this->unit->report();
-
-The report will be formatted in an HTML table for viewing. If you prefer
-the raw data you can retrieve an array using::
-
-	echo $this->unit->result();
-
-Strict Mode
-===========
-
-By default the unit test class evaluates literal matches loosely.
-Consider this example::
-
-	$this->unit->run(1, TRUE);
-
-The test is evaluating an integer, but the expected result is a boolean.
-PHP, however, due to it's loose data-typing will evaluate the above code
-as TRUE using a normal equality test::
-
-	if (1 == TRUE) echo 'This evaluates as true';
-
-If you prefer, you can put the unit test class in to strict mode, which
-will compare the data type as well as the value::
-
-	if (1 === TRUE) echo 'This evaluates as FALSE';
-
-To enable strict mode use this::
-
-	$this->unit->use_strict(TRUE);
-
-Enabling/Disabling Unit Testing
-===============================
-
-If you would like to leave some testing in place in your scripts, but
-not have it run unless you need it, you can disable unit testing using::
-
-	$this->unit->active(FALSE);
-
-Unit Test Display
-=================
-
-When your unit test results display, the following items show by
-default:
-
--  Test Name (test_name)
--  Test Datatype (test_datatype)
--  Expected Datatype (res_datatype)
--  Result (result)
--  File Name (file)
--  Line Number (line)
--  Any notes you entered for the test (notes)
-
-You can customize which of these items get displayed by using
-$this->unit->set_test_items(). For example, if you only wanted the test name
-and the result displayed:
-
-Customizing displayed tests
----------------------------
-
-::
-
-	$this->unit->set_test_items(array('test_name', 'result'));
-
-Creating a Template
--------------------
-
-If you would like your test results formatted differently then the
-default you can set your own template. Here is an example of a simple
-template. Note the required pseudo-variables::
-
-	$str = '
-	<table border="0" cellpadding="4" cellspacing="1">
-	{rows}
-		<tr>
-			<td>{item}</td>
-			<td>{result}</td>
-		</tr>
-	{/rows}
-	</table>';
-
-	$this->unit->set_template($str);
-
-.. note:: Your template must be declared **before** running the unit
-	test process.
-

-URI Class
-#########
-
-The URI Class provides methods that help you retrieve information from
-your URI strings. If you use URI routing, you can also retrieve
-information about the re-routed segments.
-
-.. note:: This class is initialized automatically by the system so there
-	is no need to do it manually.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_URI
-
-	.. php:method:: segment($n[, $no_result = NULL])
-
-		:param	int	$n: Segment index number
-		:param	mixed	$no_result: What to return if the searched segment is not found
-		:returns:	Segment value or $no_result value if not found
-		:rtype:	mixed
-
-		Permits you to retrieve a specific segment. Where n is the segment
-		number you wish to retrieve. Segments are numbered from left to right.
-		For example, if your full URL is this::
-
-			http://example.com/index.php/news/local/metro/crime_is_up
-
-		The segment numbers would be this:
-
-		#. news
-		#. local
-		#. metro
-		#. crime_is_up
-
-		The optional second parameter defaults to NULL and allows you to set the return value
-		of this method when the requested URI segment is missing.
-		For example, this would tell the method to return the number zero in the event of failure::
-
-			$product_id = $this->uri->segment(3, 0);
-
-		It helps avoid having to write code like this::
-
-			if ($this->uri->segment(3) === FALSE)
-			{
-				$product_id = 0;
-			}
-			else
-			{
-				$product_id = $this->uri->segment(3);
-			}
-
-	.. php:method:: rsegment($n[, $no_result = NULL])
-
-		:param	int	$n: Segment index number
-		:param	mixed	$no_result: What to return if the searched segment is not found
-		:returns:	Routed segment value or $no_result value if not found
-		:rtype:	mixed
-
-		This method is identical to ``segment()``, except that it lets you retrieve
-		a specific segment from your re-routed URI in the event you are
-		using CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
-
-	.. php:method:: slash_segment($n[, $where = 'trailing'])
-
-		:param	int	$n: Segment index number
-		:param	string	$where: Where to add the slash ('trailing' or 'leading')
-		:returns:	Segment value, prepended/suffixed with a forward slash, or a slash if not found
-		:rtype:	string
-
-		This method is almost identical to ``segment()``, except it
-		adds a trailing and/or leading slash based on the second parameter.
-		If the parameter is not used, a trailing slash added. Examples::
-
-			$this->uri->slash_segment(3);
-			$this->uri->slash_segment(3, 'leading');
-			$this->uri->slash_segment(3, 'both');
-
-		Returns:
-
-		#. segment/
-		#. /segment
-		#. /segment/
-
-	.. php:method:: slash_rsegment($n[, $where = 'trailing'])
-
-		:param	int	$n: Segment index number
-		:param	string	$where: Where to add the slash ('trailing' or 'leading')
-		:returns:	Routed segment value, prepended/suffixed with a forward slash, or a slash if not found
-		:rtype:	string
-
-		This method is identical to ``slash_segment()``, except that it lets you
-		add slashes a specific segment from your re-routed URI in the event you
-		are using CodeIgniter's :doc:`URI Routing <../general/routing>`
-		feature.
-
-	.. php:method:: uri_to_assoc([$n = 3[, $default = array()]])
-
-		:param	int	$n: Segment index number
-		:param	array	$default: Default values
-		:returns:	Associative URI segments array
-		:rtype:	array
-
-		This method lets you turn URI segments into an associative array of
-		key/value pairs. Consider this URI::
-
-			index.php/user/search/name/joe/location/UK/gender/male
-
-		Using this method you can turn the URI into an associative array with
-		this prototype::
-
-			[array]
-			(
-				'name'		=> 'joe'
-				'location'	=> 'UK'
-				'gender'	=> 'male'
-			)
-
-		The first parameter lets you set an offset, which defaults to 3 since your
-		URI will normally contain a controller/method pair in the first and second segments.
-		Example::
-
-			$array = $this->uri->uri_to_assoc(3);
-			echo $array['name'];
-
-		The second parameter lets you set default key names, so that the array
-		returned will always contain expected indexes, even if missing from the URI.
-		Example::
-
-			$default = array('name', 'gender', 'location', 'type', 'sort');
-			$array = $this->uri->uri_to_assoc(3, $default);
-
-		If the URI does not contain a value in your default, an array index will
-		be set to that name, with a value of NULL.
-
-		Lastly, if a corresponding value is not found for a given key (if there
-		is an odd number of URI segments) the value will be set to NULL.
-
-	.. php:method:: ruri_to_assoc([$n = 3[, $default = array()]])
-
-		:param	int	$n: Segment index number
-		:param	array	$default: Default values
-		:returns:	Associative routed URI segments array
-		:rtype:	array
-
-		This method is identical to ``uri_to_assoc()``, except that it creates
-		an associative array using the re-routed URI in the event you are using
-		CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
-
-	.. php:method:: assoc_to_uri($array)
-
-		:param	array	$array: Input array of key/value pairs
-		:returns:	URI string
-		:rtype:	string
-
-		Takes an associative array as input and generates a URI string from it.
-		The array keys will be included in the string. Example::
-
-			$array = array('product' => 'shoes', 'size' => 'large', 'color' => 'red');
-			$str = $this->uri->assoc_to_uri($array);
-
-			// Produces: product/shoes/size/large/color/red
-
-	.. php:method:: uri_string()
-
-		:returns:	URI string
-		:rtype:	string
-
-		Returns a string with the complete URI. For example, if this is your full URL::
-
-			http://example.com/index.php/news/local/345
-
-		The method would return this::
-
-			news/local/345
-
-	.. php:method:: ruri_string()
-
-		:returns:	Routed URI string
-		:rtype:	string
-
-		This method is identical to ``uri_string()``, except that it returns

-		Routing <../general/routing>` feature.
-
-	.. php:method:: total_segments()

-
-Like most other classes in CodeIgniter, the User Agent class is
-initialized in your controller using the $this->load->library function::
-
-	$this->load->library('user_agent');
-
-Once loaded, the object will be available using: ``$this->agent``
-
-User Agent Definitions
-======================
-
-The user agent name definitions are located in a config file located at:
-application/config/user_agents.php. You may add items to the various
-user agent arrays if needed.
-
-Example
-=======
-
-When the User Agent class is initialized it will attempt to determine
-whether the user agent browsing your site is a web browser, a mobile
-device, or a robot. It will also gather the platform information if it
-is available.
-
-::
-
-	$this->load->library('user_agent');
-
-	if ($this->agent->is_browser())
-	{
-		$agent = $this->agent->browser().' '.$this->agent->version();
-	}
-	elseif ($this->agent->is_robot())
-	{
-		$agent = $this->agent->robot();
-	}
-	elseif ($this->agent->is_mobile())
-	{
-		$agent = $this->agent->mobile();
-	}
-	else
-	{
-		$agent = 'Unidentified User Agent';
-	}
-
-	echo $agent;
-
-	echo $this->agent->platform(); // Platform info (Windows, Linux, Mac, etc.)

-XML-RPC and XML-RPC Server Classes
-##################################
-
-CodeIgniter's XML-RPC classes permit you to send requests to another
-server, or set up your own XML-RPC server to receive requests.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-****************
-What is XML-RPC?
-****************
-
-Quite simply it is a way for two computers to communicate over the
-internet using XML. One computer, which we will call the client, sends
-an XML-RPC **request** to another computer, which we will call the
-server. Once the server receives and processes the request it will send
-back a **response** to the client.
-
-For example, using the MetaWeblog API, an XML-RPC Client (usually a
-desktop publishing tool) will send a request to an XML-RPC Server
-running on your site. This request might be a new weblog entry being
-sent for publication, or it could be a request for an existing entry for
-editing. When the XML-RPC Server receives this request it will examine
-it to determine which class/method should be called to process the
-request. Once processed, the server will then send back a response
-message.
-
-For detailed specifications, you can visit the `XML-RPC <http://www.xmlrpc.com/>`_ site.
-
-***********************
-Using the XML-RPC Class
-***********************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the XML-RPC and XML-RPCS classes
-are initialized in your controller using the $this->load->library
-function:
-
-To load the XML-RPC class you will use::
-
-	$this->load->library('xmlrpc');
-
-Once loaded, the xml-rpc library object will be available using:
-$this->xmlrpc
-
-To load the XML-RPC Server class you will use::
-
-	$this->load->library('xmlrpc');
-	$this->load->library('xmlrpcs');
-
-Once loaded, the xml-rpcs library object will be available using:
-$this->xmlrpcs
-
-.. note:: When using the XML-RPC Server class you must load BOTH the
-	XML-RPC class and the XML-RPC Server class.
-
-Sending XML-RPC Requests
-========================
-
-To send a request to an XML-RPC server you must specify the following
-information:
-
--  The URL of the server
--  The method on the server you wish to call
--  The *request* data (explained below).
-
-Here is a basic example that sends a simple Weblogs.com ping to the
-`Ping-o-Matic <http://pingomatic.com/>`_
-
-::
-
-	$this->load->library('xmlrpc');
-
-	$this->xmlrpc->server('http://rpc.pingomatic.com/', 80);
-	$this->xmlrpc->method('weblogUpdates.ping');
-
-	$request = array('My Photoblog', 'http://www.my-site.com/photoblog/');
-	$this->xmlrpc->request($request);
-
-	if ( ! $this->xmlrpc->send_request())
-	{
-		echo $this->xmlrpc->display_error();
-	}
-
-Explanation
------------
-
-The above code initializes the XML-RPC class, sets the server URL and
-method to be called (weblogUpdates.ping). The request (in this case, the
-title and URL of your site) is placed into an array for transportation,
-and compiled using the request() function. Lastly, the full request is
-sent. If the send_request() method returns false we will display the
-error message sent back from the XML-RPC Server.
-
-Anatomy of a Request
-====================
-
-An XML-RPC request is simply the data you are sending to the XML-RPC
-server. Each piece of data in a request is referred to as a request
-parameter. The above example has two parameters: The URL and title of
-your site. When the XML-RPC server receives your request, it will look
-for parameters it requires.
-
-Request parameters must be placed into an array for transportation, and
-each parameter can be one of seven data types (strings, numbers, dates,
-etc.). If your parameters are something other than strings you will have
-to include the data type in the request array.
-
-Here is an example of a simple array with three parameters::
-
-	$request = array('John', 'Doe', 'www.some-site.com');
-	$this->xmlrpc->request($request);
-
-If you use data types other than strings, or if you have several
-different data types, you will place each parameter into its own array,
-with the data type in the second position::
-
-	$request = array(
-		array('John', 'string'),
-		array('Doe', 'string'),
-		array(FALSE, 'boolean'),
-		array(12345, 'int')
-	); 
-	$this->xmlrpc->request($request);
-
-The `Data Types <#datatypes>`_ section below has a full list of data
-types.
-
-Creating an XML-RPC Server
-==========================
-
-An XML-RPC Server acts as a traffic cop of sorts, waiting for incoming
-requests and redirecting them to the appropriate functions for
-processing.
-
-To create your own XML-RPC server involves initializing the XML-RPC
-Server class in your controller where you expect the incoming request to
-appear, then setting up an array with mapping instructions so that
-incoming requests can be sent to the appropriate class and method for
-processing.
-
-Here is an example to illustrate::
-
-	$this->load->library('xmlrpc');
-	$this->load->library('xmlrpcs');
-
-	$config['functions']['new_post'] = array('function' => 'My_blog.new_entry');
-	$config['functions']['update_post'] = array('function' => 'My_blog.update_entry');
-	$config['object'] = $this;
-
-	$this->xmlrpcs->initialize($config);
-	$this->xmlrpcs->serve();
-
-The above example contains an array specifying two method requests that
-the Server allows. The allowed methods are on the left side of the
-array. When either of those are received, they will be mapped to the
-class and method on the right.
-
-The 'object' key is a special key that you pass an instantiated class
-object with, which is necessary when the method you are mapping to is
-not part of the CodeIgniter super object.
-
-In other words, if an XML-RPC Client sends a request for the new_post
-method, your server will load the My_blog class and call the new_entry
-function. If the request is for the update_post method, your server
-will load the My_blog class and call the ``update_entry()`` method.
-
-The function names in the above example are arbitrary. You'll decide
-what they should be called on your server, or if you are using
-standardized APIs, like the Blogger or MetaWeblog API, you'll use their
-function names.
-
-There are two additional configuration keys you may make use of when
-initializing the server class: debug can be set to TRUE in order to
-enable debugging, and xss_clean may be set to FALSE to prevent sending
-data through the Security library's ``xss_clean()`` method.
-
-Processing Server Requests
-==========================
-
-When the XML-RPC Server receives a request and loads the class/method
-for processing, it will pass an object to that method containing the
-data sent by the client.
-
-Using the above example, if the new_post method is requested, the
-server will expect a class to exist with this prototype::
-
-	class My_blog extends CI_Controller {
-
-		public function new_post($request)
-		{
-
-		}
-	}
-
-The $request variable is an object compiled by the Server, which
-contains the data sent by the XML-RPC Client. Using this object you will
-have access to the *request parameters* enabling you to process the
-request. When you are done you will send a Response back to the Client.
-
-Below is a real-world example, using the Blogger API. One of the methods
-in the Blogger API is ``getUserInfo()``. Using this method, an XML-RPC
-Client can send the Server a username and password, in return the Server
-sends back information about that particular user (nickname, user ID,
-email address, etc.). Here is how the processing function might look::
-
-	class My_blog extends CI_Controller {
-
-		public function getUserInfo($request)
-		{
-			$username = 'smitty';
-			$password = 'secretsmittypass';
-
-			$this->load->library('xmlrpc');
-
-			$parameters = $request->output_parameters();
-
-			if ($parameters[1] != $username && $parameters[2] != $password)
-			{
-				return $this->xmlrpc->send_error_message('100', 'Invalid Access');
-			}
-
-			$response = array(
-				array(
-					'nickname'  => array('Smitty', 'string'),
-					'userid'    => array('99', 'string'),
-					'url'       => array('http://yoursite.com', 'string'),
-					'email'     => array('jsmith@yoursite.com', 'string'),
-					'lastname'  => array('Smith', 'string'),
-					'firstname' => array('John', 'string')
-				),
-	                         'struct'
-			);
-
-			return $this->xmlrpc->send_response($response);
-		}
-	}
-
-Notes:
-------
-
-The ``output_parameters()`` method retrieves an indexed array
-corresponding to the request parameters sent by the client. In the above
-example, the output parameters will be the username and password.
-
-If the username and password sent by the client were not valid, and
-error message is returned using ``send_error_message()``.
-
-If the operation was successful, the client will be sent back a response
-array containing the user's info.
-
-Formatting a Response
-=====================
-
-Similar to *Requests*, *Responses* must be formatted as an array.
-However, unlike requests, a response is an array **that contains a
-single item**. This item can be an array with several additional arrays,
-but there can be only one primary array index. In other words, the basic
-prototype is this::
-
-	$response = array('Response data', 'array');
-
-Responses, however, usually contain multiple pieces of information. In
-order to accomplish this we must put the response into its own array so
-that the primary array continues to contain a single piece of data.
-Here's an example showing how this might be accomplished::
-
-	$response = array(
-		array(
-			'first_name' => array('John', 'string'),
-			'last_name' => array('Doe', 'string'),
-			'member_id' => array(123435, 'int'),
-			'todo_list' => array(array('clean house', 'call mom', 'water plants'), 'array'),
-		),
-		'struct'
-	);
-
-Notice that the above array is formatted as a struct. This is the most
-common data type for responses.
-
-As with Requests, a response can be one of the seven data types listed
-in the `Data Types <#datatypes>`_ section.
-
-Sending an Error Response
-=========================
-
-If you need to send the client an error response you will use the
-following::
-
-	return $this->xmlrpc->send_error_message('123', 'Requested data not available');
-
-The first parameter is the error number while the second parameter is
-the error message.
-
-Creating Your Own Client and Server
-===================================
-
-To help you understand everything we've covered thus far, let's create a
-couple controllers that act as XML-RPC Client and Server. You'll use the
-Client to send a request to the Server and receive a response.
-
-The Client
-----------
-
-Using a text editor, create a controller called Xmlrpc_client.php. In
-it, place this code and save it to your application/controllers/
-folder::
-
-	<?php
-
-	class Xmlrpc_client extends CI_Controller {
-
-		public function index()
-		{
-			$this->load->helper('url');
-			$server_url = site_url('xmlrpc_server');
-
-			$this->load->library('xmlrpc');
-
-			$this->xmlrpc->server($server_url, 80);
-			$this->xmlrpc->method('Greetings');
-
-			$request = array('How is it going?');
-			$this->xmlrpc->request($request);
-
-			if ( ! $this->xmlrpc->send_request())
-			{
-				echo $this->xmlrpc->display_error();
-			}
-			else
-			{
-				echo '<pre>';
-				print_r($this->xmlrpc->display_response());
-				echo '</pre>';
-			}
-		}
-	}
-	?>
-
-.. note:: In the above code we are using a "url helper". You can find more
-	information in the :doc:`Helpers Functions <../general/helpers>` page.
-
-The Server
-----------
-
-Using a text editor, create a controller called Xmlrpc_server.php. In
-it, place this code and save it to your application/controllers/
-folder::
-
-	<?php
-
-	class Xmlrpc_server extends CI_Controller {
-
-		public function index()
-		{
-			$this->load->library('xmlrpc');
-			$this->load->library('xmlrpcs');
-
-			$config['functions']['Greetings'] = array('function' => 'Xmlrpc_server.process');
-
-			$this->xmlrpcs->initialize($config);
-			$this->xmlrpcs->serve();
-		}
-
-
-		public function process($request)
-		{
-			$parameters = $request->output_parameters();
-
-			$response = array(
-				array(
-					'you_said'  => $parameters[0],
-					'i_respond' => 'Not bad at all.'
-				),
-				'struct'
-			);
-
-			return $this->xmlrpc->send_response($response);
-		}
-	}
-
-
-Try it!
--------
-
-Now visit the your site using a URL similar to this::
-
-	example.com/index.php/xmlrpc_client/
-
-You should now see the message you sent to the server, and its response
-back to you.
-
-The client you created sends a message ("How's is going?") to the
-server, along with a request for the "Greetings" method. The Server
-receives the request and maps it to the ``process()`` method, where a
-response is sent back.
-
-Using Associative Arrays In a Request Parameter
-===============================================
-
-If you wish to use an associative array in your method parameters you
-will need to use a struct datatype::
-
-	$request = array(
-		array(
-			// Param 0
-			array('name' => 'John'),
-			'struct'
-		),
-		array(
-			// Param 1
-			array(
-				'size' => 'large',
-				'shape'=>'round'
-			),
-			'struct'
-		)
-	);
-
-	$this->xmlrpc->request($request);
-
-You can retrieve the associative array when processing the request in
-the Server.
-
-::
-
-	$parameters = $request->output_parameters();
-	$name = $parameters[0]['name'];
-	$size = $parameters[1]['size'];
-	$shape = $parameters[1]['shape'];
-
-Data Types
-==========
-
-According to the `XML-RPC spec <http://www.xmlrpc.com/spec>`_ there are
-seven types of values that you can send via XML-RPC:
-
--  *int* or *i4*
--  *boolean*
--  *string*
--  *double*
--  *dateTime.iso8601*
--  *base64*
--  *struct* (contains array of values)
--  *array* (contains array of values)

-Zip Encoding Class
-##################
-
-CodeIgniter's Zip Encoding Class permits you to create Zip archives.
-Archives can be downloaded to your desktop or saved to a directory.
-
-.. contents::
-  :local:
-
-.. raw:: html
-
-  <div class="custom-index container"></div>
-
-****************************
-Using the Zip Encoding Class
-****************************
-
-Initializing the Class
-======================
-
-Like most other classes in CodeIgniter, the Zip class is initialized in
-your controller using the $this->load->library function::
-
-	$this->load->library('zip');
-
-Once loaded, the Zip library object will be available using::
-
-	$this->zip
-
-Usage Example
-=============
-
-This example demonstrates how to compress a file, save it to a folder on
-your server, and download it to your desktop.
-
-::
-
-	$name = 'mydata1.txt';
-	$data = 'A Data String!';
-
-	$this->zip->add_data($name, $data);
-
-	// Write the zip file to a folder on your server. Name it "my_backup.zip"
-	$this->zip->archive('/path/to/directory/my_backup.zip');
-
-	// Download the file to your desktop. Name it "my_backup.zip"
-	$this->zip->download('my_backup.zip');
-
-***************
-Class Reference
-***************
-
-.. php:class:: CI_Zip
-
-	.. attribute:: $compression_level = 2
-
-		The compression level to use.
-
-		It can range from 0 to 9, with 9 being the highest and 0 effectively disabling compression::
-
-			$this->zip->compression_level = 0;
-
-	.. php:method:: add_data($filepath[, $data = NULL])
-
-		:param	mixed	$filepath: A single file path or an array of file => data pairs
-		:param	array	$data: File contents (ignored if $filepath is an array)
-		:rtype:	void
-
-		Adds data to the Zip archive. Can work both in single and multiple files mode.
-
-		When adding a single file, the first parameter must contain the name you would
-		like given to the file and the second must contain the file contents::
-
-			$name = 'mydata1.txt';
-			$data = 'A Data String!';
-			$this->zip->add_data($name, $data);
-
-			$name = 'mydata2.txt';
-			$data = 'Another Data String!';
-			$this->zip->add_data($name, $data);
-
-		When adding multiple files, the first parameter must contain *file => contents* pairs
-		and the second parameter is ignored::
-
-			$data = array(
-				'mydata1.txt' => 'A Data String!',
-				'mydata2.txt' => 'Another Data String!'
-			);
-
-			$this->zip->add_data($data);
-
-		If you would like your compressed data organized into sub-directories, simply include
-		the path as part of the filename(s)::
-
-			$name = 'personal/my_bio.txt';
-			$data = 'I was born in an elevator...';
-
-			$this->zip->add_data($name, $data);
-
-		The above example will place my_bio.txt inside a folder called personal.
-
-	.. php:method:: add_dir($directory)
-
-		:param	mixed	$directory: Directory name string or an array of multiple directories
-		:rtype:	void
-
-		Permits you to add a directory. Usually this method is unnecessary since you can place
-		your data into directories when using ``$this->zip->add_data()``, but if you would like
-		to create an empty directory you can do so::
-
-			$this->zip->add_dir('myfolder'); // Creates a directory called "myfolder"
-
-	.. php:method:: read_file($path[, $archive_filepath = FALSE])
-
-		:param	string	$path: Path to file
-		:param	mixed	$archive_filepath: New file name/path (string) or (boolean) whether to maintain the original filepath
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		Permits you to compress a file that already exists somewhere on your server.
-		Supply a file path and the zip class will read it and add it to the archive::
-
-			$path = '/path/to/photo.jpg';
-
-			$this->zip->read_file($path);
-
-			// Download the file to your desktop. Name it "my_backup.zip"
-			$this->zip->download('my_backup.zip');
-
-		If you would like the Zip archive to maintain the directory structure of
-		the file in it, pass TRUE (boolean) in the second parameter. Example::
-
-			$path = '/path/to/photo.jpg';
-
-			$this->zip->read_file($path, TRUE);
-
-			// Download the file to your desktop. Name it "my_backup.zip"
-			$this->zip->download('my_backup.zip');
-
-		In the above example, photo.jpg will be placed into the *path/to/* directory.
-
-		You can also specify a new name (path included) for the added file on the fly::
-
-			$path = '/path/to/photo.jpg';
-			$new_path = '/new/path/some_photo.jpg';
-
-			$this->zip->read_file($path, $new_path);
-
-			// Download ZIP archive containing /new/path/some_photo.jpg
-			$this->zip->download('my_archive.zip');
-
-	.. php:method:: read_dir($path[, $preserve_filepath = TRUE[, $root_path = NULL]])
-
-		:param	string	$path: Path to directory
-		:param	bool	$preserve_filepath: Whether to maintain the original path
-		:param	string	$root_path: Part of the path to exclude from the archive directory
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		Permits you to compress a directory (and its contents) that already exists somewhere on your server.
-		Supply a path to the directory and the zip class will recursively read and recreate it as a Zip archive.
-		All files contained within the supplied path will be encoded, as will any sub-directories contained within it. Example::
-
-			$path = '/path/to/your/directory/';
-
-			$this->zip->read_dir($path);
-
-			// Download the file to your desktop. Name it "my_backup.zip"
-			$this->zip->download('my_backup.zip');
-
-		By default the Zip archive will place all directories listed in the first parameter
-		inside the zip. If you want the tree preceding the target directory to be ignored,
-		you can pass FALSE (boolean) in the second parameter. Example::
-
-			$path = '/path/to/your/directory/';
-
-			$this->zip->read_dir($path, FALSE);
-
-		This will create a ZIP with a directory named "directory" inside, then all sub-directories
-		stored correctly inside that, but will not include the */path/to/your* part of the path.
-
-	.. php:method:: archive($filepath)
-
-		:param	string	$filepath: Path to target zip archive
-		:returns:	TRUE on success, FALSE on failure
-		:rtype:	bool
-
-		Writes the Zip-encoded file to a directory on your server. Submit a valid server path
-		ending in the file name. Make sure the directory is writable (755 is usually OK).
-		Example::
-
-			$this->zip->archive('/path/to/folder/myarchive.zip'); // Creates a file named myarchive.zip
-
-	.. php:method:: download($filename = 'backup.zip')
-
-		:param	string	$filename: Archive file name
-		:rtype:	void
-
-		Causes the Zip file to be downloaded from your server.
-		You must pass the name you would like the zip file called. Example::
-
-			$this->zip->download('latest_stuff.zip'); // File will be named "latest_stuff.zip"
-
-		.. note:: Do not display any data in the controller in which you call
-			this method since it sends various server headers that cause the
-			download to happen and the file to be treated as binary.
-
-	.. php:method:: get_zip()
-
-		:returns:	Zip file content
-		:rtype:	string
-
-		Returns the Zip-compressed file data. Generally you will not need this method unless you
-		want to do something unique with the data. Example::
-
-			$name = 'my_bio.txt';
-			$data = 'I was born in an elevator...';
-
-			$this->zip->add_data($name, $data);
-
-			$zip_file = $this->zip->get_zip();
-
-	.. php:method:: clear_data()
-
-		:rtype:	void
-
-		The Zip class caches your zip data so that it doesn't need to recompile the Zip archive
-		for each method you use above. If, however, you need to create multiple Zip archives,
-		each with different data, you can clear the cache between calls. Example::
-
-			$name = 'my_bio.txt';
-			$data = 'I was born in an elevator...';
-
-			$this->zip->add_data($name, $data);
-			$zip_file = $this->zip->get_zip();
-
-			$this->zip->clear_data();
-
-			$name = 'photo.jpg';
-			$this->zip->read_file("/path/to/photo.jpg"); // Read the file's contents
-
-			$this->zip->download('myphotos.zip');

-Application Flow Chart
-######################
-
-The following graphic illustrates how data flows throughout the system:
-
-|CodeIgniter application flow|
-
-#. The index.php serves as the front controller, initializing the base
-   resources needed to run CodeIgniter.
-#. The Router examines the HTTP request to determine what should be done
-   with it.
-#. If a cache file exists, it is sent directly to the browser, bypassing
-   the normal system execution.
-#. Security. Before the application controller is loaded, the HTTP
-   request and any user submitted data is filtered for security.
-#. The Controller loads the model, core libraries, helpers, and any
-   other resources needed to process the specific request.
-#. The finalized View is rendered then sent to the web browser to be
-   seen. If caching is enabled, the view is cached first so that on
-   subsequent requests it can be served.

-#######################
-CodeIgniter at a Glance
-#######################
-
-CodeIgniter is an Application Framework
-=======================================
-
-CodeIgniter is a toolkit for people who build web applications using
-PHP. Its goal is to enable you to develop projects much faster than you
-could if you were writing code from scratch, by providing a rich set of
-libraries for commonly needed tasks, as well as a simple interface and
-logical structure to access these libraries. CodeIgniter lets you
-creatively focus on your project by minimizing the amount of code needed
-for a given task.
-
-CodeIgniter is Free
-===================
-
-CodeIgniter is licensed under the MIT license so you can use it however
-you please. For more information please read the
-:doc:`license agreement <../license>`.
-
-CodeIgniter is Light Weight
-===========================
-
-Truly light weight. The core system requires only a few very small
-libraries. This is in stark contrast to many frameworks that require
-significantly more resources. Additional libraries are loaded
-dynamically upon request, based on your needs for a given process, so
-the base system is very lean and quite fast.
-
-CodeIgniter is Fast
-===================
-
-Really fast. We challenge you to find a framework that has better
-performance than CodeIgniter.
-
-CodeIgniter Uses M-V-C
-======================
-
-CodeIgniter uses the Model-View-Controller approach, which allows great
-separation between logic and presentation. This is particularly good for
-projects in which designers are working with your template files, as the
-code these files contain will be minimized. We describe MVC in more
-detail on its own page.
-
-CodeIgniter Generates Clean URLs
-================================
-
-The URLs generated by CodeIgniter are clean and search-engine friendly.
-Rather than using the standard "query string" approach to URLs that is
-synonymous with dynamic systems, CodeIgniter uses a segment-based
-approach::
-
-	example.com/news/article/345
-
-.. note:: By default the *index.php* file is included in the URL but it can
-	be removed using a simple *.htaccess* file.
-
-CodeIgniter Packs a Punch
-=========================
-
-CodeIgniter comes with full-range of libraries that enable the most
-commonly needed web development tasks, like accessing a database,
-sending email, validating form data, maintaining sessions, manipulating
-images, working with XML-RPC data and much more.
-
-CodeIgniter is Extensible
-=========================
-
-The system can be easily extended through the use of your own libraries,
-helpers, or through class extensions or system hooks.
-
-CodeIgniter Does Not Require a Template Engine
-==============================================
-
-Although CodeIgniter *does* come with a simple template parser that can
-be optionally used, it does not force you to use one. Template engines
-simply can not match the performance of native PHP, and the syntax that
-must be learned to use a template engine is usually only marginally
-easier than learning the basics of PHP. Consider this block of PHP code::
-
-	<ul>
-	<?php foreach ($addressbook as $name):?>
-		<li><?=$name?></li>
-	<?php endforeach; ?>
-	</ul>
-
-Contrast this with the pseudo-code used by a template engine::
-
-	<ul>
-	{foreach from=$addressbook item="name"}
-		<li>{$name}</li>
-	{/foreach}
-	</ul>
-
-Yes, the template engine example is a bit cleaner, but it comes at the
-price of performance, as the pseudo-code must be converted back into PHP
-to run. Since one of our goals is *maximum performance*, we opted to not
-require the use of a template engine.
-
-CodeIgniter is Thoroughly Documented
-====================================
-
-Programmers love to code and hate to write documentation. We're no
-different, of course, but since documentation is **as important** as the
-code itself, we are committed to doing it. Our source code is extremely
-clean and well commented as well.
-
-CodeIgniter has a Friendly Community of Users
-=============================================
-
-Our growing community of users can be seen actively participating in our
-`Community Forums <http://forum.codeigniter.com/>`_.

-CodeIgniter Features
-####################
-
-Features in and of themselves are a very poor way to judge an
-application since they tell you nothing about the user experience, or
-how intuitively or intelligently it is designed. Features don't reveal
-anything about the quality of the code, or the performance, or the
-attention to detail, or security practices. The only way to really judge
-an app is to try it and get to know the code.
-:doc:`Installing <../installation/index>` CodeIgniter is child's play so
-we encourage you to do just that. In the mean time here's a list of
-CodeIgniter's main features.

-################################
-Getting Started With CodeIgniter
-################################
-
-Any software application requires some effort to learn. We've done our
-best to minimize the learning curve while making the process as
-enjoyable as possible.
-
-The first step is to :doc:`install <../installation/index>`
-CodeIgniter, then read all the topics in the **Introduction** section of
-the Table of Contents.
-
-Next, read each of the **General Topics** pages in order. Each topic
-builds on the previous one, and includes code examples that you are
-encouraged to try.
-
-Once you understand the basics you'll be ready to explore the **Class
-Reference** and **Helper Reference** pages to learn to utilize the
-native libraries and helper files.
-
-Feel free to take advantage of our `Community
-Forums <http://forum.codeigniter.com/>`_ if you have questions or
-problems, and our `Wiki <https://github.com/bcit-ci/CodeIgniter/wiki>`_ to see code

-##############################
-Design and Architectural Goals
-##############################
-
-Our goal for CodeIgniter is maximum performance, capability, and
-flexibility in the smallest, lightest possible package.
-
-To meet this goal we are committed to benchmarking, re-factoring, and
-simplifying at every step of the development process, rejecting anything
-that doesn't further the stated objective.
-
-From a technical and architectural standpoint, CodeIgniter was created
-with the following objectives:
-
--  **Dynamic Instantiation.** In CodeIgniter, components are loaded and
-   routines executed only when requested, rather than globally. No
-   assumptions are made by the system regarding what may be needed
-   beyond the minimal core resources, so the system is very light-weight
-   by default. The events, as triggered by the HTTP request, and the
-   controllers and views you design will determine what is invoked.
--  **Loose Coupling.** Coupling is the degree to which components of a
-   system rely on each other. The less components depend on each other
-   the more reusable and flexible the system becomes. Our goal was a
-   very loosely coupled system.
--  **Component Singularity.** Singularity is the degree to which
-   components have a narrowly focused purpose. In CodeIgniter, each
-   class and its functions are highly autonomous in order to allow
-   maximum usefulness.
-
-CodeIgniter is a dynamically instantiated, loosely coupled system with
-high component singularity. It strives for simplicity, flexibility, and
-high performance in a small footprint package.

-#####################
-Model-View-Controller
-#####################
-
-CodeIgniter is based on the Model-View-Controller development pattern.
-MVC is a software approach that separates application logic from
-presentation. In practice, it permits your web pages to contain minimal
-scripting since the presentation is separate from the PHP scripting.
-
--  The **Model** represents your data structures. Typically your model
-   classes will contain functions that help you retrieve, insert, and
-   update information in your database.
--  The **View** is the information that is being presented to a user. A
-   View will normally be a web page, but in CodeIgniter, a view can also
-   be a page fragment like a header or footer. It can also be an RSS
-   page, or any other type of "page".
--  The **Controller** serves as an *intermediary* between the Model, the
-   View, and any other resources needed to process the HTTP request and
-   generate a web page.
-
-CodeIgniter has a fairly loose approach to MVC since Models are not
-required. If you don't need the added separation, or find that
-maintaining models requires more complexity than you want, you can
-ignore them and build your application minimally using Controllers and
-Views. CodeIgniter also enables you to incorporate your own existing
-scripts, or even develop core libraries for the system, enabling you to
-work in a way that makes the most sense to you.

-Conclusion
-##########
-
-This tutorial did not cover all of the things you might expect of a
-full-fledged content management system, but it introduced you to the
-more important topics of routing, writing controllers, and models. We
-hope this tutorial gave you an insight into some of CodeIgniter's basic
-design patterns, which you can expand upon.
-
-Now that you've completed this tutorial, we recommend you check out the
-rest of the documentation. CodeIgniter is often praised because of its
-comprehensive documentation. Use this to your advantage and read the
-"Introduction" and "General Topics" sections thoroughly. You should read
-the class and helper references when needed.
-
-Every intermediate PHP programmer should be able to get the hang of
-CodeIgniter within a few days.
-
-If you still have questions about the framework or your own CodeIgniter
-code, you can:

-Create news items
-#################
-
-You now know how you can read data from a database using CodeIgniter, but
-you haven't written any information to the database yet. In this section
-you'll expand your news controller and model created earlier to include
-this functionality.
-
-Create a form
--------------
-
-To input data into the database you need to create a form where you can
-input the information to be stored. This means you'll be needing a form
-with two fields, one for the title and one for the text. You'll derive
-the slug from our title in the model. Create the new view at
-*application/views/news/create.php*.
-
-::
-
-    <h2><?php echo $title; ?></h2>
-
-    <?php echo validation_errors(); ?>
-
-    <?php echo form_open('news/create'); ?>
-
-        <label for="title">Title</label> 
-        <input type="input" name="title" /><br />
-
-        <label for="text">Text</label>
-        <textarea name="text"></textarea><br />
-
-        <input type="submit" name="submit" value="Create news item" /> 
-
-    </form>
-
-There are only two things here that probably look unfamiliar to you: the
-``form_open()`` function and the ``validation_errors()`` function.
-
-The first function is provided by the :doc:`form
-helper <../helpers/form_helper>` and renders the form element and
-adds extra functionality, like adding a hidden :doc:`CSRF prevention
-field <../libraries/security>`. The latter is used to report
-errors related to form validation.
-
-Go back to your news controller. You're going to do two things here,
-check whether the form was submitted and whether the submitted data
-passed the validation rules. You'll use the :doc:`form
-validation <../libraries/form_validation>` library to do this.
-
-::
-
-    public function create()
-    {
-        $this->load->helper('form');
-        $this->load->library('form_validation');
-        
-        $data['title'] = 'Create a news item';
-        
-        $this->form_validation->set_rules('title', 'Title', 'required');
-        $this->form_validation->set_rules('text', 'Text', 'required');
-        
-        if ($this->form_validation->run() === FALSE)
-        {
-            $this->load->view('templates/header', $data);   
-            $this->load->view('news/create');
-            $this->load->view('templates/footer');
-            
-        }
-        else
-        {
-            $this->news_model->set_news();
-            $this->load->view('news/success');
-        }
-    }
-
-The code above adds a lot of functionality. The first few lines load the
-form helper and the form validation library. After that, rules for the
-form validation are set. The ``set_rules()`` method takes three arguments;
-the name of the input field, the name to be used in error messages, and
-the rule. In this case the title and text fields are required.
-
-CodeIgniter has a powerful form validation library as demonstrated
-above. You can read :doc:`more about this library
-here <../libraries/form_validation>`.
-
-Continuing down, you can see a condition that checks whether the form
-validation ran successfully. If it did not, the form is displayed, if it
-was submitted **and** passed all the rules, the model is called. After
-this, a view is loaded to display a success message. Create a view at
-*application/views/news/success.php* and write a success message.
-
-Model
------
-
-The only thing that remains is writing a method that writes the data to
-the database. You'll use the Query Builder class to insert the
-information and use the input library to get the posted data. Open up
-the model created earlier and add the following:
-
-::
-
-    public function set_news()
-    {
-        $this->load->helper('url');
-        
-        $slug = url_title($this->input->post('title'), 'dash', TRUE);
-        
-        $data = array(
-            'title' => $this->input->post('title'),
-            'slug' => $slug,
-            'text' => $this->input->post('text')
-        );
-        
-        return $this->db->insert('news', $data);
-    }
-
-This new method takes care of inserting the news item into the database.
-The third line contains a new function, url\_title(). This function -
-provided by the :doc:`URL helper <../helpers/url_helper>` - strips down
-the string you pass it, replacing all spaces by dashes (-) and makes
-sure everything is in lowercase characters. This leaves you with a nice
-slug, perfect for creating URIs.
-
-Let's continue with preparing the record that is going to be inserted
-later, inside the ``$data`` array. Each element corresponds with a column in
-the database table created earlier. You might notice a new method here,
-namely the ``post()`` method from the :doc:`input
-library <../libraries/input>`. This method makes sure the data is
-sanitized, protecting you from nasty attacks from others. The input
-library is loaded by default. At last, you insert our ``$data`` array into
-our database.
-
-Routing
--------
-
-Before you can start adding news items into your CodeIgniter application
-you have to add an extra rule to *config/routes.php* file. Make sure your
-file contains the following. This makes sure CodeIgniter sees 'create'
-as a method instead of a news item's slug.
-
-::
-
-    $route['news/create'] = 'news/create';
-    $route['news/(:any)'] = 'news/view/$1';
-    $route['news'] = 'news';
-    $route['(:any)'] = 'pages/view/$1';
-    $route['default_controller'] = 'pages/view';
-
-Now point your browser to your local development environment where you
-installed CodeIgniter and add index.php/news/create to the URL.
-Congratulations, you just created your first CodeIgniter application!
-Add some news and check out the different pages you made.

-Tutorial
-########
-
-This tutorial is intended to introduce you to the CodeIgniter framework
-and the basic principles of MVC architecture. It will show you how a
-basic CodeIgniter application is constructed in step-by-step fashion.
-
-In this tutorial, you will be creating a **basic news application**. You
-will begin by writing the code that can load static pages. Next, you
-will create a news section that reads news items from a database.
-Finally, you'll add a form to create news items in the database.
-
-This tutorial will primarily focus on:
-
--  Model-View-Controller basics
--  Routing basics
--  Form validation
--  Performing basic database queries using "Query Builder"
-
-The entire tutorial is split up over several pages, each explaining a
-small part of the functionality of the CodeIgniter framework. You'll go
-through the following pages:
-
--  Introduction, this page, which gives you an overview of what to
-   expect.
--  :doc:`Static pages <static_pages>`, which will teach you the basics
-   of controllers, views and routing.
--  :doc:`News section <news_section>`, where you'll start using models
-   and will be doing some basic database operations.
--  :doc:`Create news items <create_news_items>`, which will introduce
-   more advanced database operations and form validation.
--  :doc:`Conclusion <conclusion>`, which will give you some pointers on
-   further reading and other resources.
-
-Enjoy your exploration of the CodeIgniter framework.

-############
-News section
-############
-
-In the last section, we went over some basic concepts of the framework
-by writing a class that includes static pages. We cleaned up the URI by
-adding custom routing rules. Now it's time to introduce dynamic content
-and start using a database.
-
-Setting up your model
----------------------
-
-Instead of writing database operations right in the controller, queries
-should be placed in a model, so they can easily be reused later. Models
-are the place where you retrieve, insert, and update information in your
-database or other data stores. They represent your data.
-
-Open up the *application/models/* directory and create a new file called
-*News_model.php* and add the following code. Make sure you've configured
-your database properly as described :doc:`here <../database/configuration>`.
-
-::
-
-	<?php
-	class News_model extends CI_Model {
-
-		public function __construct()
-		{
-			$this->load->database();
-		}
-	}
-
-This code looks similar to the controller code that was used earlier. It
-creates a new model by extending ``CI_Model`` and loads the database
-library. This will make the database class available through the
-``$this->db`` object.
-
-Before querying the database, a database schema has to be created.
-Connect to your database and run the SQL command below (MySQL).
-Also add some seed records.
-
-::
-
-	CREATE TABLE news (
-		id int(11) NOT NULL AUTO_INCREMENT,
-		title varchar(128) NOT NULL,
-		slug varchar(128) NOT NULL,
-		text text NOT NULL,
-		PRIMARY KEY (id),
-		KEY slug (slug)
-	);
-
-Now that the database and a model have been set up, you'll need a method
-to get all of our posts from our database. To do this, the database
-abstraction layer that is included with CodeIgniter — 
-:doc:`Query Builder <../database/query_builder>` — is used. This makes it
-possible to write your 'queries' once and make them work on :doc:`all
-supported database systems <../general/requirements>`. Add the
-following code to your model.
-
-::
-
-	public function get_news($slug = FALSE)
-	{
-		if ($slug === FALSE)
-		{
-			$query = $this->db->get('news');
-			return $query->result_array();
-		}
-
-		$query = $this->db->get_where('news', array('slug' => $slug));
-		return $query->row_array();
-	}
-
-With this code you can perform two different queries. You can get all
-news records, or get a news item by its `slug <#>`_. You might have
-noticed that the ``$slug`` variable wasn't sanitized before running the
-query; :doc:`Query Builder <../database/query_builder>` does this for you.
-
-Display the news
-----------------
-
-Now that the queries are written, the model should be tied to the views
-that are going to display the news items to the user. This could be done
-in our ``Pages`` controller created earlier, but for the sake of clarity,
-a new ``News`` controller is defined. Create the new controller at
-*application/controllers/News.php*.
-
-::
-
-	<?php
-	class News extends CI_Controller {
-
-		public function __construct()
-		{
-			parent::__construct();
-			$this->load->model('news_model');
-			$this->load->helper('url_helper');
-		}
-
-		public function index()
-		{
-			$data['news'] = $this->news_model->get_news();
-		}
-
-		public function view($slug = NULL)
-		{
-			$data['news_item'] = $this->news_model->get_news($slug);
-		}
-	}
-
-Looking at the code, you may see some similarity with the files we
-created earlier. First, the ``__construct()`` method: it calls the
-constructor of its parent class (``CI_Controller``) and loads the model,
-so it can be used in all other methods in this controller.
-It also loads a collection of :doc:`URL Helper <../helpers/url_helper>`
-functions, because we'll use one of them in a view later.
-
-Next, there are two methods to view all news items and one for a specific
-news item. You can see that the ``$slug`` variable is passed to the model's
-method in the second method. The model is using this slug to identify the
-news item to be returned.
-
-Now the data is retrieved by the controller through our model, but
-nothing is displayed yet. The next thing to do is passing this data to
-the views.
-
-::
-
-	public function index()
-	{
-		$data['news'] = $this->news_model->get_news();
-		$data['title'] = 'News archive';
-
-		$this->load->view('templates/header', $data);
-		$this->load->view('news/index', $data);
-		$this->load->view('templates/footer');
-	}
-
-The code above gets all news records from the model and assigns it to a
-variable. The value for the title is also assigned to the ``$data['title']``
-element and all data is passed to the views. You now need to create a
-view to render the news items. Create *application/views/news/index.php*
-and add the next piece of code.
-
-::
-
-	<h2><?php echo $title; ?></h2>
-	
-	<?php foreach ($news as $news_item): ?>
-
-		<h3><?php echo $news_item['title']; ?></h3>
-		<div class="main">
-			<?php echo $news_item['text']; ?>
-		</div>
-		<p><a href="<?php echo site_url('news/'.$news_item['slug']); ?>">View article</a></p>
-
-	<?php endforeach; ?>
-
-Here, each news item is looped and displayed to the user. You can see we
-wrote our template in PHP mixed with HTML. If you prefer to use a template
-language, you can use CodeIgniter's :doc:`Template
-Parser <../libraries/parser>` class or a third party parser.
-
-The news overview page is now done, but a page to display individual
-news items is still absent. The model created earlier is made in such
-way that it can easily be used for this functionality. You only need to
-add some code to the controller and create a new view. Go back to the
-``News`` controller and update ``view()`` with the following:
-
-::
-
-	public function view($slug = NULL)
-	{
-		$data['news_item'] = $this->news_model->get_news($slug);
-
-		if (empty($data['news_item']))
-		{
-			show_404();
-		}
-
-		$data['title'] = $data['news_item']['title'];
-
-		$this->load->view('templates/header', $data);
-		$this->load->view('news/view', $data);
-		$this->load->view('templates/footer');
-	}
-
-Instead of calling the ``get_news()`` method without a parameter, the
-``$slug`` variable is passed, so it will return the specific news item.
-The only things left to do is create the corresponding view at
-*application/views/news/view.php*. Put the following code in this file.
-
-::
-
-	<?php
-	echo '<h2>'.$news_item['title'].'</h2>';
-	echo $news_item['text'];
-
-Routing
--------
-
-Because of the wildcard routing rule created earlier, you need an extra
-route to view the controller that you just made. Modify your routing file
-(*application/config/routes.php*) so it looks as follows.
-This makes sure the requests reaches the ``News`` controller instead of
-going directly to the ``Pages`` controller. The first line routes URI's
-with a slug to the ``view()`` method in the ``News`` controller.
-
-::
-
-	$route['news/(:any)'] = 'news/view/$1';
-	$route['news'] = 'news';
-	$route['(:any)'] = 'pages/view/$1';
-	$route['default_controller'] = 'pages/view';
-
-Point your browser to your document root, followed by index.php/news and
-watch your news page.

-############
-Static pages
-############
-
-**Note:** This tutorial assumes you've downloaded CodeIgniter and
-:doc:`installed the framework <../installation/index>` in your
-development environment.
-
-The first thing you're going to do is set up a **controller** to handle
-static pages. A controller is simply a class that helps delegate work.
-It is the glue of your web application.
-
-For example, when a call is made to:
-
-	http://example.com/news/latest/10
-
-We might imagine that there is a controller named "news". The method
-being called on news would be "latest". The news method's job could be to
-grab 10 news items, and render them on the page. Very often in MVC,
-you'll see URL patterns that match:
-
-	http://example.com/[controller-class]/[controller-method]/[arguments]
-
-As URL schemes become more complex, this may change. But for now, this
-is all we will need to know.
-
-Create a file at *application/controllers/Pages.php* with the following
-code.
-
-::
-
-	<?php 
-	class Pages extends CI_Controller { 
-
-		public function view($page = 'home') 
-		{
-	        }
-	}
-
-You have created a class named ``Pages``, with a view method that accepts
-one argument named ``$page``. The ``Pages`` class is extending the
-``CI_Controller`` class. This means that the new pages class can access the
-methods and variables defined in the ``CI_Controller`` class
-(*system/core/Controller.php*).
-
-The **controller is what will become the center of every request** to
-your web application. In very technical CodeIgniter discussions, it may
-be referred to as the *super object*. Like any php class, you refer to
-it within your controllers as ``$this``. Referring to ``$this`` is how
-you will load libraries, views, and generally command the framework.
-
-Now you've created your first method, it's time to make some basic page
-templates. We will be creating two "views" (page templates) that act as
-our page footer and header.
-
-Create the header at *application/views/templates/header.php* and add
-the following code:
-
-::
-
-	<html>
-		<head>
-			<title>CodeIgniter Tutorial</title>
-		</head>
-		<body>
-
-			<h1><?php echo $title; ?></h1>
-
-The header contains the basic HTML code that you'll want to display
-before loading the main view, together with a heading. It will also
-output the ``$title`` variable, which we'll define later in the controller.
-Now, create a footer at *application/views/templates/footer.php* that
-includes the following code:
-
-::
-
-			<em>&copy; 2015</em>
-		</body>
-	</html>
-
-Adding logic to the controller
-------------------------------
-
-Earlier you set up a controller with a ``view()`` method. The method
-accepts one parameter, which is the name of the page to be loaded. The
-static page templates will be located in the *application/views/pages/*
-directory.
-
-In that directory, create two files named *home.php* and *about.php*.
-Within those files, type some text − anything you'd like − and save them.
-If you like to be particularly un-original, try "Hello World!".
-
-In order to load those pages, you'll have to check whether the requested
-page actually exists:
-
-::
-
-	public function view($page = 'home')
-	{
-	        if ( ! file_exists(APPPATH.'views/pages/'.$page.'.php'))
-		{
-			// Whoops, we don't have a page for that!
-			show_404();
-		}
-
-		$data['title'] = ucfirst($page); // Capitalize the first letter
-
-		$this->load->view('templates/header', $data);
-		$this->load->view('pages/'.$page, $data);
-		$this->load->view('templates/footer', $data);
-	}
-
-Now, when the page does exist, it is loaded, including the header and
-footer, and displayed to the user. If the page doesn't exist, a "404
-Page not found" error is shown.
-
-The first line in this method checks whether the page actually exists.
-PHP's native ``file_exists()`` function is used to check whether the file
-is where it's expected to be. ``show_404()`` is a built-in CodeIgniter
-function that renders the default error page.
-
-In the header template, the ``$title`` variable was used to customize the
-page title. The value of title is defined in this method, but instead of
-assigning the value to a variable, it is assigned to the title element
-in the ``$data`` array.
-
-The last thing that has to be done is loading the views in the order
-they should be displayed. The second parameter in the ``view()`` method is
-used to pass values to the view. Each value in the ``$data`` array is
-assigned to a variable with the name of its key. So the value of
-``$data['title']`` in the controller is equivalent to ``$title`` in the
-view.
-
-Routing
--------
-
-The controller is now functioning! Point your browser to
-``[your-site-url]index.php/pages/view`` to see your page. When you visit
-``index.php/pages/view/about`` you'll see the about page, again including
-the header and footer.
-
-Using custom routing rules, you have the power to map any URI to any
-controller and method, and break free from the normal convention:
-``http://example.com/[controller-class]/[controller-method]/[arguments]``
-
-Let's do that. Open the routing file located at
-*application/config/routes.php* and add the following two lines.
-Remove all other code that sets any element in the ``$route`` array.
-
-::
-
-	$route['default_controller'] = 'pages/view';
-	$route['(:any)'] = 'pages/view/$1';
-
-CodeIgniter reads its routing rules from top to bottom and routes the
-request to the first matching rule. Each rule is a regular expression
-(left-side) mapped to a controller and method name separated by slashes
-(right-side). When a request comes in, CodeIgniter looks for the first
-match, and calls the appropriate controller and method, possibly with
-arguments.
-
-More information about routing can be found in the URI Routing
-:doc:`documentation <../general/routing>`.
-
-Here, the second rule in the ``$routes`` array matches **any** request
-using the wildcard string ``(:any)``. and passes the parameter to the
-``view()`` method of the ``Pages`` class.
-
-Now visit ``index.php/about``. Did it get routed correctly to the ``view()``
-method in the pages controller? Awesome!
