run code in 300+ PHP versions simultaneously
<?php function x($n){ for($i=1;$i<$n;$i++){ $n%$i ? : $f[]=$i; } echo array_sum($f)==$n?"P":"I"; } x(28);

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).
