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.

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.

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"><</span><span class="nx">ul</span><span class="o">></span> -<span class="o"><?</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">?></span> - <span class="p"><</span><span class="nt">li</span><span class="p">></span><span class="cp"><?</span><span class="o">=</span><span class="nv">$name</span><span class="cp">?></span><span class="p"></</span><span class="nt">li</span><span class="p">></span> -<span class="cp"><?php</span> <span class="k">endforeach</span><span class="p">;</span> <span class="cp">?></span> -<span class="p"></</span><span class="nt">ul</span><span class="p">></span> -</pre></div> -</div> -<p>Contrast this with the pseudo-code used by a template engine:</p> -<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o"><</span><span class="nx">ul</span><span class="o">></span> -<span class="p">{</span><span class="k">foreach</span> <span class="nx">from</span><span class="o">=</span><span class="nv">$addressbook</span> <span class="nx">item</span><span class="o">=</span><span class="s2">"name"</span><span class="p">}</span> - <span class="o"><</span><span class="nx">li</span><span class="o">></span><span class="p">{</span><span class="nv">$name</span><span class="p">}</span><span class="o"></</span><span class="nx">li</span><span class="o">></span> -<span class="p">{</span><span class="o">/</span><span class="k">foreach</span><span class="p">}</span> -<span class="o"></</span><span class="nx">ul</span><span class="o">></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.
