Sequence number

[rob01]

Hi,

could someone help me out with this one?

Currently I'm using an Open Source php-script to process my forms. (I don't have any knowledge of php to write it myself so...).

I have to develop an orderform and I would like to know if it was possible to generate a unique sequence number each time a visitor hits the submit button. That unique number should show up in the mail that I'm getting in my mailbox.
I think php and a text file might do the trick (like it also works for a polling script that I'm using. But as I said, I don't know enough about php to rewrite this polling code and make it work for my sequence number).

It would totally be awsome if I could automatically send an e-mail to that person, to tell him what his unique number is. If that's too complicated, no problem, then I send that mail manually.

Is there someone who knows a solution for this 'problem' and how I should implement it in the script that I'm using at this moment?

Thanks very much!!!
Rob

Consider [man]uniqid/man and [man]mail/man

[adi]

use uniqid();

<? 
$unique=uniqid();
echo "$unique";
?>

or:

<?
$moreunique= md5(uniqid());
echo "$moreunique";
