Random Number Generator

**SeanFlaherty** · #1 (**permalink**) 01-16-2007, 03:46 AM

In PHP, I'm going to make a random number generator, but I don't exactly know how... And can someone show me a code that does random numbers?

Hi.

Try this.

PHP Code:

  <?

srand(time());

$random = (rand()%9);

print("random number between 0 and 9 is: $random");

?>

If you want to know what it looks like in a browser, i have uploaded a test for it here refresh the page, and the number should change. (If it doesn't refresh again)
Hope this helps

Of course, a computer only generates pseudo-random numbers since it's processor is completley logical. So if you're after really random numbers take a look at Random.org - True Random Number Service. But PHP's "random" numbers should be fine for most situations.

Okay, thanks both of you. I'll try both of these
