run code in 300+ PHP versions simultaneously
<?php $num1 = "5"; $num2 = "6"; function multi() { global $num1,$num2; $num2 = null; } multi(); echo $num2; var_dump($GLOBALS);

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).
