PHP excluding numbers from rand() function

Question

I'm running rand() 3 times, and I want to exclude the first two results from the possibilities of the function. Like if it hit 1 and 5, I want the next rand() to exclude 1 and 5 from its range. How would I do this?

Answer 1

How about:

do {   
    $rand_number = rand();

}while(in_array($rand_number, array(1,5));

Answer 2

If you want to generate three unique random(ish) numbers, you could use:

$totalNumsNeeded = 3;
$randoms = array();
while (count($randoms) < $totalNumsNeeded) {
    $random = rand($min, $max);
    if (!in_array($random, $randoms)) {
        $randoms[] = $random;
    }
}
