run code in 300+ PHP versions simultaneously
<?php $n = null; echo $n++; echo "\nSomething else\n"; $n = null; echo ++$n; echo "\nSomething else again\n"; $n = null; $n++; echo $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).
