You can create GUIDs manually:

function getGUID(){     if (function_exists('com_create_guid')){         return com_create_guid();     }     else {         mt_srand((double)microtime()*10000);//optional for php 4.2.0 and up.         $charid = strtoupper(md5(uniqid(rand(), true)));         $hyphen = chr(45);// "-"         $uuid = chr(123)// "{"             .substr($charid, 0, 8).$hyphen             .substr($charid, 8, 4).$hyphen             .substr($charid,12, 4).$hyphen             .substr($charid,16, 4).$hyphen             .substr($charid,20,12)             .chr(125);// "}"         return $uuid;     } }

$GUID = getGUID(); echo $GUID;
