Random function

[Desdinova]

This doesn't seem possible with rand();

what I need is, I have say 32 options. I want to select a number between 1 and 32. How should I do this?

If you want a random number between 5 and 15 (inclusive), for example, use rand (5, 15).

with that in mind, for your solution, you simply need to do the following:
[code]
$i = rand(1, 32);
[/code]

yeah you're right.

php.net explanes it badly. I thought rand(1,30) would create a 30char long random string.

thanks:)

the manual definitely can be difficult to understand at times... that's why we're here ;-)
