Loop Help...

[Anon]

I need to generate a new random number on each loop...

I have

for($loop = 1; $loop <= 10000; $loop++)
{
srand(time());
unset($numbercheck1);
unset($numbercheck);
$numbercheck = rand(1,605);
$numbercheck1 = rand(1,274);

Wich I believe should work, but no luck.

What are you trying to do? Only use srand once per script. Also, no need to unset it here, it will just be written over. Here's an example use, a modification of your code ... try it and see what happens. Also, explain what you are wanting to do.

<?php
srand ((double) microtime() * 1000000);

for($loop = 1; $loop <= 100; $loop++)
{
echo '<br>a ' . $numbercheck = rand(1,605);
echo '<br>b ' . $numbercheck1 = rand(1,274);
}
?>

Thanks, its working. I kept recalling the sead, why did that make all my numbers the same>?

PHP code executes very fast and time() only changes each second. So for every loop within the same second, you were seeding it with the same number, thus the same "random" number.

The seed is there for debuggin. you can seed it with a constant number to get the same sequence of "random" numbers while you are testing. Once you're done testing, then you seed it with something that changes, like time() or microtime(), but you only seed it once in the beginning.
