<?php class a { public static function ii(){ var_dump($this); } } class b { public function ii(){ $a = new a(); $a->ii(); } } $bb = new b(); $bb->ii();

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).
