run code in 300+ PHP versions simultaneously
<?php a = new stdClass; print spl_object_hash($a) ."\n"; unset($a); $a = new stdClass; print spl_object_hash($a) ."\n";

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).
