<?php class A{ function A(){ $this->a['s'] = 'hoge'; } function B(){ $s =& $this->a['s']; $this->o($s); var_dump($s); } function o($s){ $s = 'da' . $s; } } $a = new A(); $a->B();

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).
