Description:
------------
With PHP 4 you could create the object variable before the actual object was defined. This doesnt seem to be true in 5. If you move lines 2 and 3 of the code to the bottom the script oes work, but this does break backward compatibility.

Reproduce code:
---------------
<?php
$new_obj = new new_class;
$new_obj->hello ();

class new_class
	{
	function hello ()
		{
		echo "Hello";
		}
	}
?>

Expected result:
----------------
Hello

Actual result:
--------------
Fatal error: Class 'new_class' not found in /usr/local/apache2/htdocs/scripts/class_test.php on line 2
