run code in 300+ PHP versions simultaneously
<?php $foo = true; function get(): string { return 'hello'; } if ($foo) { echo get(); } else { echo null; }

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).
