<?php function f(int $a, int $b = null, int $c = null) { error_log(json_encode([$a, $b, $c])); error_log(json_encode(func_get_args())); } function changeF($code, $str) { preg_match('/^Argument (\\d+) /', $str, $m); $i = $m[1]-1; $bt = debug_backtrace(null, 2); ++$bt[1]['args'][$i]; return true; } set_error_handler('changeF', E_ALL); f(3, 2, 1);

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).
