You're code doesn't make sense. You're looking for 3 random numbers, between
1 and 3 inclusive. Umm.. 1,2,3.
Do you want them in a random order, or something?
Maybe the upper limit of rand() and how many numbers you're looking for
($n), should be different??

Subject: [PHP] Random Function
Hi, I have the following function that generates a random number, but the
key is it only generates the number once within the range you specify. So,
if you want a range of 5 numbers, it will give you 5 different numbers. My
problem is the function was set to start at 0, but I need it to start at 1,
so i made a change to the function (line 9) and now the script only works
every now and then. Can somebody look at it and see if they see why it would
be doing that? Thanks
<?php
$s = array();
$n = 3;
function set_num() {
File random0.php saved.
$ cat random0.php
<?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();
}
?>
