run code in 300+ PHP versions simultaneously
<?php $temp = '+1000'; echp strlen($temp); if (is_string($temp)) {echo 'true';} echo round($temp);

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).
