<?php class A { private $foo = 'a'; public function __toString() { echo 'why would you do this?'; return $this->foo; } } $a = new A(); echo $a;

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).
