<?php namespace NS { class A { function test() { echo 'test'; } } } namespace NS2 { class_alias( 'NS\A', 'B' ); } namespace NS3 { class MyClass extends \B { function test() { echo 'test under MyClass'; } } } namespace NS4 { function foo (\NS\A $f) { $f->test(); } foo (new \NS3\MyClass); }

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).
