Hi, I have this banners rotator script:

<?php
//randomly shuffle the array keeping the relation between keys and values
function shuffle_me($shuffle_me){
$randomized_keys = array_rand($shuffle_me, count($shuffle_me));
foreach($randomized_keys as $current_key) {
$shuffled_me[$current_key] = $shuffle_me[$current_key];
}
return $shuffled_me;
}
$center_banners=shuffle_me($center_banners);
$center_banners=array_slice($center_banners, 0, 20);

$left_banners=shuffle_me($left_banners);
$right_banners=shuffle_me($right_banners);
?>

OK, the script runs perfectly at a PHP4 server, but it doesn't work at my current PHP5 server.

I think that the reason is the change at the array_rand log:
5.2.10 - The resulting array of keys is no longer shuffled.

What exactly do I need to change at the script to work at PHP5? As the script is part of a topsite, it is interrelated with multiple programming pages so the change should be the minimum necessary to work with PHP5.

I have done multiple test without results. Consider that my PHP skills are so low. Please, help me!

    Surely if the function array_rand() no longer shuffles the keys into a random order, then this function is most likely not what you will want to use in PHP5.

      You can use the shuffle function to preserve the keys if you need to - with a little creativity. This example is on the shuffle() manual reference page... (Untested, but the code looks like it should work to serve your needs).

      function kshuffle(&$array) {
    if(!is_array($array) || empty($array)) {
        return false;
    }
    $tmp = array();
    foreach($array as $key => $value) {
        $tmp[] = array('k' => $key, 'v' => $value);
    }
    shuffle($tmp);
    $array = array();
    foreach($tmp as $entry) {
        $array[$entry['k']] = $entry['v'];
    }
    return true;
}

// Usage (assuming your array is named "$shuffle_me")
kshuffle($shuffle_me);
