run code in 300+ PHP versions simultaneously
<?php function x($n) { for($i = 1; $i <= $n; $i++) { $n % $i == 0 && $i != $n ? $factors[]=$i & $i!=$n : 0; } array_sum($factors) == $n ? printf('P') : printf('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).
