The documentation says it should return false.

"Returns the name of the class of which object is an instance. Returns

FALSE if object is not an object."

It's very inconsistent if in PHP 5.2 it returns false and in 5.3 null.

invalid argument returns NULL, not false.

Description:
------------
get_class returns NULL when using it with a string instead of FALSE.

Reproduce code:
---------------
<?php
var_dump(get_class('test'));

Expected result:
----------------
bool(false)






Actual result:
--------------
Warning: get_class() expects parameter 1 to be object, string given in

/home/wiebe/run.php on line 34
NULL
