<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>
