[serious1234]

i have a script that randomly chooses questions and answers from mysql datase. i used rand  but the problem is when I refresh the page everything changes new questions and new answers. is there a way I can make these questions and the answers not change when refreshing the page.

You want something which is random, but doesn't change?

Before selecting the random question and answers:

If (!isset($_COOKIE['randomSeed'])) {
   list($usec, $sec) = explode(' ', microtime());
   $seed = (float) $sec + ((float) $usec * 100000);
   setcookie('randomSeed', $seed);
} else {
   $seed = $_COOKIE['randomSeed'];
}
srand($seed);

Use php rand to generate the random questions and answers

 

When questions are answered, remove the cookie

Are you saying you want to randomly generate a question/answer when you get to a page but not re-generate if the page is refreshed?
