run code in 300+ PHP versions simultaneously
<?php $array = []; var_dump(empty($array)); // outputs bool(false) $array = new ArrayObject(); var_dump(empty($array)); // outputs bool(false)

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).
