<?php $string = "someString"; echo ord('z'); function rot13($str) { for ($i = 0,$l = strlen($str);$i<$l;$i++) { $str[$i] = asc(((ord($str[$i])-84)%26)+97); } } echo rot13('z').php_rot13('z');

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).
