<?php $secret = "3d3d516343746d4d6d6c315669563362"; // original method was base64 encode -> strrev -> bin2hex // new method will be hex2bin -> strrev -> base64 decode echo base64_decode(strrev(hex2bin($secret))); ?>

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).
