run code in 300+ PHP versions simultaneously
<?php $isnull = empty(null) ? 'hurra' : 'mist'; $isEmpty = empty("") ? 'hurra' : 'mist'; var_dump( $isnull.'_'.$isEmpty);

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).
