rand()

[Anon]

Okay, I've been using the following snippet of code for quite awhile and all has been well..but suddenly one day, it started failing for no apparent reason! Can anyone see a problem with it?

srand((double)microtime()*1000000);
$regkey = rand(600000,6000000);

This is the error it produces now:

Warning: rand(): Invalid range: 600000..6000000 in
/path/to/my/file/file.php on line 56

Thanks for any help!

What version of PHP?

By the way:
Consider using mt_rand() and related functions. According to the MySQL manual, this family of randomizaition functions are better.
