2 Random integers

[gple]

how do I pull out two random integers at the same time without ever possibly choosing the same integer twice?

Just in theory:

 

$random1 = get_random_int();

do

{

    $random2 = get_random_int();

} while($random1 != $random2); // Get a new random number untill they are different.

<?php
$a= rand(1,3);
$b = rand(1, 3);
while($a == $b)$b=rand(1,3);
echo "$a - $b";
?>
