Go to the manual at http://be2.php.net/manual/en/function.rand.php and
look at the User contributed notes further down the page. You'll find a
couple of solutions.
Whatever you do, you will presumably need to check the generated number
against the db to see if it is already in use and, if not, generate a
new random number.
Good luck,

Hello,
I'm learning PhP and trying to write a library catalogue system, that uses a PostgreSQL back-end. My db looks like this ...
http://www.chez.com/desmondcoughlan/unix/bibliotheque.sql
I had originally planned to have a username in place of 'card_number', but
realised that there was no point. What I need now is the PhP code that will
create a card number, and rather than having a sequence, I want a random
three-digit number. Can someone point me in the direction of where and how PhP
can do this?
Thanks.
D.
