Re: random 'card number' generator

D. 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.

X-No-Archive: true 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. --------------------------------- Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions !
