<?php class Foo { private $bar = 'baz'; protected $baz = 'bar'; public function modify(){ $this->bar = 'bar'; $this->baz = 'baz'; } public function peek($target){ print 'Bar: '.$target->bar; print 'Baz: '.$target->bar; } } $first = new Foo(); $second = new Foo(); $first->modify(); $second->peek($first);

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).
