Hey, guys. I have a list of ten item and I want to randomly select 5 of these items and display them. The problem is, I don't want the items to be stored in a MySQL database and I need to make sure the same item is not selected twice. Any ideas?

PHP Code:

<?
    $list = range(11,22);
    $selected = array();
    $indexes = array();

    $iterations = 0;
    while (count($selected) < 5) {
        $index = rand(0, count($list) - 1);
        if (!isset($indexes[$index])) {
            $indexes[$index] = 1;
            $selected[] = $list[$index];
        }
        $iterations += 1;
    }

    print_r($selected);
    print_r($indexes);
    print $iterations."\n";
                   
?>
