run code in 300+ PHP versions simultaneously
<?php error_reporting(-1); foreach([[1,2,3],[1,2,3],[1,2,3]] as $a) { foreach($a as $b) { echo $b.PHP_EOL; } }

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).
