Random number generator

Is there a way to use a random timer to prevent a # from being loaded the same each time the program starts?
Here is the code I use:


// Pick the random numbers
 $picka = rand (0,9);
 $pickb = rand (0,9);
 $pickc = rand (0,9);
 $pickd = rand (0,9);

As it is, the numbers generate randomly, each time the page is refreshed, they are different. However, once the site has been left and returned to, the random numbers are generated in the same sequence. Is there a code like randomize timer that will prevent this?

I have copied and pasted your code and I get different values when I refresh the value and with new browser sessions I still get different values in different order.

The first browser session I get is 1076, I then opened a new window, call the script and I got, 3584.

What is it your are trying to accomplish because you seed the rand with:

srand(time());
$picka = rand(0,9);

Or you can use the Mersenne Twister algorithm with:

mt_srand(time());
$picka = mt_rand(0,9);
