rand () and mt_rand()

gregburns61

I have looked everywhere and can't seem to get the rand() command working. Especially when refreshing the page.

Here is my code

Any suggestions?

Thanks

Try this:
<?php
mt_srand(time());
print(mt_rand(1,10));
?>

Hope it helps!

I'm not sure why it works but I now that you have to seed the generator with something!

Thank you Stephen.

This works great.

Apparently you need to shuffle the deck before you pick a number. The mt_srand command simulates this activity. I had been using the same seed value every time, by using the time function you can seed the mt_srand() function with a different value every time you load the page, (ie. this shuffles the deck or seeds the mt_srand with a new value, this cause the mt_rand function to generate a new random number).

That's my story and I'm sticking to it.

Thanks again!

Good problem solving skills Stephen, I should have thought of it myself.
