note 9592 added to md5

If you want some numbers that are actually unique, don't reley on md5 or any other kind of checksum. If you think about it, if all binary sequences can be collapsed to a 32 character md5 checksum you are going to get a lot of repeats. Why not use uniqid? It does generate uniqid's; md5 does not. The good thing about md5 and other checksum's is tht it is hard to calculate what the dat was that could have generated the checksum. Sam http://www.php.net/manual/function.md5.php
