run code in 300+ PHP versions simultaneously
<?php $class = new stdClass; echo (empty($class) ? 'empty' : 'not empty'); echo PHP_EOL; $array = []; echo (empty($array) ? 'empty' : 'not empty');

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).
