run code in 300+ PHP versions simultaneously
<?php $a=1; $b=0; switch($a) { default: $b += 1; break; default: $b += 2; } echo $b; //output would be 2

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).
