run code in 300+ PHP versions simultaneously
<?php $var = null; $e = &$var; try { throw new Exception; } catch (Exception $e) { } assert('$e !== null'); assert('$var !== 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).
