Sorry, i copied a little extra stuff from console. This is what it is,
Anyways, it works fine if I put 0 in for 1 on line 9 where it uses the
rand(), but it include 0 and I can't have 0. Is there some way to fix that?
If you need to see the demo of it working with the 0 in place, i can do
that.
<?php
$s = array();
$n = 3;
function set_num() {
global $s, $n;
$add = "yes";
$ran = rand(1, $n);
if(count($s) > 0) {
foreach($s as $sh) {
if($ran == $sh) {
$add = "no";
}
}
}
if($add == "yes") {
$s[] = $ran;
} else {
set_num();
}
}
while(count($s) <= $n) {
set_num();
}
?>
