Yes.
If you have a look at the PHP code (or Lua for scripts), there is a helper method that generates UUID.

Can you point me to that helper?

For generating type 4 UUIDs I use this simple bit of code, it's not my work but I don't know where it came from:

#!/usr/bin/php
<?php

echo sprintf( '%04x%04x-%04x-%04x-%04x-%04x%04x%04x',
    mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff ),
    mt_rand( 0, 0xffff ),
    mt_rand( 0, 0x0fff ) | 0x4000,
    mt_rand( 0, 0x3fff ) | 0x8000,
    mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff ), mt_rand( 0, 0xffff ))."\n";

?>
