run code in 300+ PHP versions simultaneously
<?php $foo = (float) (PHP_INT_MAX ) $foo *= 2; if ($foo == 1.844674407371E+19) { echo "true"; } else { echo "$foo != 1.844674407371E+19"; }

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).
