check the manual on the rand(); function ..
If you want to make sure this number is unique .. create an array storing
all the numbers you've used once and do some nice tricks with a loop and
stuff untill you get a nice unique random number ... like this:
?php
$UsedValues = Array();
function
How do i generate a unique random number?
You can use rand(), but there's no guarantee it'll be unique unless you
remember every number you've ever generated
