Hi Russell, Have a look at

Hi Russell,

Have a look at uniqid() which should do what you want (assuming that numbers and letters are OK) - a neat thing to do is to use strtoupper() and just take the last 10 characters, for example:

$userID = substr(strtoupper(uniqid()),-10) 

Hope this helps!
Cheers,
David.
