<?php function generate_GUID() { $uuid = md5(uniqid(rand(), true)); print_r($uuid);exit; $guid = substr($uuid,0,8)."-". substr($uuid,8,4)."-". substr($uuid,12,4)."-". substr($uuid,16,4)."-". substr($uuid,20,12); return $guid; } echo strtoupper(generate_GUID());

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).
