<?php class InCommon { public function out(){ echo "BAZ: ".$this->baz; } } class Foo extends InCommon { private $baz = 'foo'; } class Bar extends InCommon { private $baz = 'bar'; public function mess($target){ $target->baz = 'cats'; } } $foo = new Foo(); $bar = new Bar(); $bar->mess($foo); $foo->out();

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).
