__autoload and including files
<p>I have a site which uses the library file <code>lib.client.php</code> which is stored in the <code>php</code> folder in my standard website root and contains a series of classes I have built.</p>

<p>I am going to have to <code>require_once</code> this library file in almost every single page, what is the best way I can implement this? Furthermore, should I be using some conbination of functions using <code>__autoload</code> to accomplish this?</p>

<p>Having seen a very similar question which touches on the issue but offers a very specific answer I can't really use, and looking a bit into the <code>__autoload</code> function, I want to get a more detailed answer for my requirements.</p>
