if you create an object befor you had described your class this will let crash your php code.
If you create the object after you had described your class code all is fine.

Reproduce code:
File 1 with Class 1
class f {
 var $f = null;
 function f() {
 	$this->f = 5;
File 2 with Class 2
$b = new xy();
class xy extends f{
	function xy() {
		echo $this->f;

Expected result:
The output had to be 5 

Actual result:
Fatal error: Cannot instantiate non-existent class: xy in c:\server_scripts\htdocs\scripts\test.php on line 3

You need to declared classes before use if you inherit them.
