<?php class zyf{ public $a; public $b; function zyf() { $this->$a=4; $this->$b=5; } function add($a,$b) { $c=$a+$b; echo $c; } } $xin = new zyf(); $xin->add(); ?>

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
