run code in 300+ PHP versions simultaneously
<?php $constants = get_defined_constants(); print_r(array_intersect_key($constants, array_flip(preg_grep('/^P(?:REG|CRE)_/', array_keys($constants))));

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).
