<?php namespace www; class Base { public function ec() { echo "1111";} } class A extends namespace\Base {} namespace ttt; class Base { public function ec() { echo "222";} } use \www\A as C, \ttt\A; class B extends ttt\A {} $a = new \ttt\B(); $a->ec();

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).
