-<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>

-<div class="section" id="codeigniter-is-an-application-framework">
-<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>
-</div>
-<div class="section" id="codeigniter-is-free">
-<h2>CodeIgniter is Free<a class="headerlink" href="#codeigniter-is-free" title="Permalink to this headline">¶</a></h2>
-<p>CodeIgniter is licensed under the MIT license so you can use it however
-you please. For more information please read the
-<a class="reference internal" href="../license.html"><span class="doc">license agreement</span></a>.</p>
-</div>
-<div class="section" id="codeigniter-is-light-weight">
-<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>
-</div>
-<div class="section" id="codeigniter-uses-m-v-c">
-<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>
-<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 “query string” approach to URLs that is
-synonymous with dynamic systems, CodeIgniter uses a segment-based
-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="mi">345</span>
-</pre></div>
-</div>
-<div class="admonition note">
-<p class="first admonition-title">Note</p>
-<p class="last">By default the <em>index.php</em> file is included in the URL but it can
-be removed using a simple <em>.htaccess</em> file.</p>
-</div>
-</div>
-<div class="section" id="codeigniter-packs-a-punch">
-<h2>CodeIgniter Packs a Punch<a class="headerlink" href="#codeigniter-packs-a-punch" title="Permalink to this headline">¶</a></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>
-</div>
-<div class="section" id="codeigniter-is-extensible">
-<h2>CodeIgniter is Extensible<a class="headerlink" href="#codeigniter-is-extensible" title="Permalink to this headline">¶</a></h2>
-<p>The system can be easily extended through the use of your own libraries,
-helpers, or through class extensions or system hooks.</p>
-</div>
-<div class="section" id="codeigniter-does-not-require-a-template-engine">
-<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>

-<div class="section" id="codeigniter-is-thoroughly-documented">

-<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

-<p>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.</p>
-<p>The first step is to <a class="reference internal" href="../installation/index.html"><span class="doc">install</span></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’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’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 “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>
