Easy:
replace $min and $max with whatever you like.
<?php $min = 0; $max = 100; srand((double)microtime()*1000000); echo rand($min,$max); ?>
replace $min and $max with whatever you like.

The Crazy One
RobSoftware:
All new versions of php (4+) no longer require srand before rand, it does it automaticly when rand is called.

So the new code would look like:
<?php $min = 0; $max = 100; echo rand($min,$max); ?>

That second code looks much better than the first code. I once wrote a random name generator in C++ (I don't remember how to now, it was when I was trying to learn C++), and it was pretty cool, I only used it once.
