hi friends
I need a hash function to build a Unique serial number ...

Try:

http://php.net/manual/en/function.dbplus-getunique.php

But use at your own risk.

If you want a unique number try using a time stamp (i.e., time() ) in concert with a database.

For example, grab a time, look for it in a database, if it's not there then use it. If it is there then repeat until you have that isn't. That way it's a unique number guaranteed.

Cheers,

tedd
