run code in 300+ PHP versions simultaneously
<?php $result = ['aa', 'ab', 'ba']; $current = ''; foreach($result as $val){ if($val[0] != $current) { echo 'header'; $current = $val[0]; } echo $val.'<br/>'; }

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).
