<?php function foo($b, $a) { return $b . $a; } var_dump(call_user_func_array('foo', ['a' => 'first', 'b' => 'second'])); var_dump(call_user_func_array('foo', ['first', 'second']));

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).
