Here is a function I wrote to generate an array with a unigue set of numbers in each place. You can
enter the Min and the Max number to pick from and the number of array places to generate for.
random_loop([# of Array Places], [Min], [Max]);
<?php
$cols = random_loop(9, 0, 9);
function random_loop($num, $min, $max){
$rand[0] = mt_rand($min, $max);
for($i = 1; $i<$num; $i++){
do{
$check = true;
$rand[$i] = mt_rand($min, $max);
for($ii = 0; $ii < (count($rand)-1); $ii++){
if($rand[$i] == $rand[$ii] && $check){
$check = false;
break;
}
}
}while (!$check);
}
return $rand;
}
?>
Enjoy and use at your will.
