<?php $uuid = '550e8400-e29b-41d4-a716-446655440000'; $uuid = str_replace('-', '', $uuid); $uuid = hex2bin($uuid); $uuid = base64_encode($uuid); $uuid = str_replace('=', '', $uuid); var_dump($uuid);

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).
