run code in 300+ PHP versions simultaneously
<?php if(@__TRAIT__ == '__TRAIT__'){ echo 'magic __TRAIT__ constant NOT defined'; //insert this code where needed, remember that because they are MAGIC constants defining __TRAIT__ is completely useless }echo{ echo 'magic __TRAIT__ constant IS defined'; }

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).
