run code in 300+ PHP versions simultaneously
<?php $str = "something"; print strlen($str); $test = []; $test[] = ord('shit'); print $test; print implode(' ',$test);

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).
