run code in 300+ PHP versions simultaneously
<?php $obj1 = new stdClass; $obj2 = new stdClass; assert($obj1 != $obj2, '!='); assert($obj1 !== $obj2); // Prove that fails are shown.

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).
