run code in 300+ PHP versions simultaneously
<?php class foo { function x() { echo "GOOD BYE "; return true; } function y() { echo "HELLO "; return $this->x(); } } $a = new foo; if (!$a->x() || $a->y()) { echo " :)"; }

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).
