run code in 300+ PHP versions simultaneously
<?php $goal = 'g'; function g($str = null){ echo "pwat"; $g = function ($str = null){ echo "pwet"; }; return $g; } var_dump(g());

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).
