Description:
------------
When you create a normal class you can call it before the class is defined on the page.  However, when you extend a class you cannot instantiate the class before it is declared.  It will not be found.

Reproduce code:
---------------
<?php
require_once('controller.php');

$l = new Login();

class Login extends Controller
{
	function __construct()
	{
		parent::__construct();
		echo('Extended');
	}
}
?>

Expected result:
----------------
Extended

Actual result:
--------------
Fatal error: Class 'Login' not found in ...\test.php on line 4
