<?php class A { static function foo() { echo "A\n"; } } class B extends A { static function foo() { echo "B\n"; } } $cb = array('B', 'parent::foo'); //call_user_func($cb); call_user_func(array('A','foo'));

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
