If you want to see php errors in firebug here is how you do it: <?php
 
/**
* class: Debugger
* author: <a href="http://doru.serveblog.net">Moisa Doru</a>
* contact: <a href="mailto:moisadoru@gmail.com">moisadoru@gmail.com</a>
* info: this class displays PHP errors in Firebug; works only in PHP5, tested in PHP 5.2.0
* usage: <strong>include_once("debugger.php")</strong> as the very first include();
* licence: free as in free beer ;)
