run code in 300+ PHP versions simultaneously
<?php $i = 1; $n = 2; for($f = 0; $f <= 20; $f++) { echo "F".$f." = ".$f-$i+$f-$n."\n"; $i++; $n++; }

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).
