run code in 300+ PHP versions simultaneously
<?php define('CONSTANT', 1); define('_CONSTANT', 0); define('EMPTY', ''); if (!empty('0')) { if (!(boolean) _CONSTANT) { echo 1; } } else if (constant('CONSTANT') == 1) { echo 2; }

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).
