What's the best way to extend classes in php 5.2.17?
<p>In PHP 5.3 you can quite easily write say...</p>

<pre><code>class Controller extends \Special\Controller
</code></pre>

<p>Currently I am having to work with php 5.2.17, how do you properly extend classes with this version?  I know there aren't any namespaces so I'm curious is it even possible to do this with a version &lt;5.3</p>

<p>Thanks,</p>
