PHP Output my XML feed in a random order - php

Question

I have my XML output working fine but it's in latest date order. What would be cool is if I could get it in a random order. I've tried using shuffle and I just can't get it working (nothing seems to happen).
Here's an example of the code I'm using to build my XML. The output is HTML with PHP to insert variables.
// Build the Feed
$feed = "http://www.reviewswebsite.com/api/consumer-reviews/?username=" . $userName . "&format=xml&reviews_per_page=20&page=" . $pageNumber;
$xml = simplexml_load_file($feed);
for($i = 0; $i < $numberOfForLoops; $i++)
{
$reviewer_name = $xml->reviews->review[$i]->reviewer_name;
$date_of_work = date('l, d m Y' , strtotime($xml->reviews->review[$i]->date_of_work));
$average_reviewer_rating = (float)$xml->reviews->review[$i]->average_rating;
..
?>
<div><?php echo $reviewer_name; ?></div>
...
<?php ;} ?>

#The Fourth Bird helped me by passing this link: Randomize SimpleXML object results
The end result I created for Trust-A-Trader reviews which I built into a Joomla! module was. I'll try to release the module for free on the Joomla! Extensions Directory (JED).
End code was
$feed = "http://www.trustatrader.com/api/consumer-reviews/?username=" . $userName . "&format=xml&reviews_per_page=20&page=" . $pageNumber;
$xml = simplexml_load_file($feed);
// Count Reviews, if total number of reviews is less than the total shown on page set in module then show the lesser amount to avoid an error.
$totalNumberOfReviews = count($xml->reviews->review);
$numberOfForLoops = $totalNumberOfReviews;
if ($totalNumberOfReviews > $numberOfReviews) {
$numberOfForLoops = $numberOfReviews;
}
// If the module sets the order to random then shuffle array, or else do in latest first date order.
if ($params->get('Order') == 0) {
foreach($xml->reviews->review as $val)
$array[]= $val;
shuffle($array);
}
// Loop through the reviews and output them.
foreach($array as $val)
{
$i = 0;
if ($i < $numberOfForLoops)
{
