<?php class a { public $prop; public function change() { $prop=2; } public function output() { echo $prop; } } class b { public function change() { $this->prop=2; } public function output() { echo $this->prop; echo $this; } } $objA=new a(); $objB=new b(); $objA->change(); $objA->output(); $objB->change(); $objB->output();

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).
