-<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>Helpers are intentionally kept very simple so that they can be used within your <strong>View Files</strong> with a minimal amount of code.
-This is important if you intend to have designers or non-programmer will be working with your view files, since it keeps the code to a minimum.
-</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>
-
-<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>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><?=anchor('blog/comments', 'Click Here');?></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>Now What?</h2>
-
-<p>In the <a href="../toc.html">Table of Contents</a> you'll find a list of all the available Helper Files. Browse each one to see what they do.</p>
