How to randomize image array with PHP

I am after a little help here. I need to randomize an image array's order.

For example, if I have 3 images, I need them to reload each time in a different order.

Also, this is the instructions given to me on how to implement the code:

If this is PHP code, use a return statement to send your output to the block. For example:
$my_output = 'Hello, world.';
return $my_output;

My current code is HTML, and goes like this:

<div class="ad">

<a href="http://www.linkedsite.com/" target="_blank"><img src="myimagesdirectpath/img.png"      alt="linkedsitename" /></a>

<br />
<a href="http://www.linkedsite.com/" target="_blank"><img src="myimagesdirectpath/img.png" alt="linkedsitename" /></a>

<br />
<a href="http://www.linkedsite.com/" target="_blank"><img src="myimagesdirectpath/img.png"      alt="linkedsitename" /></a>

</div>

What I need to do is somehow turn my HTML code into a PHP code that allows the images order to be randomized, while maintaining the original instructions to "Use an output statement" to send my code to the sidebar.

Thanks! and I wish I knew more

If you really need a solution before really understanding the PHP basics, here it is:

<?php
$images =   array(
            '<a href="http://www.linkedsite.com/" target="_blank"><img src="myimagesdirectpath/img.png" alt="linkedsitename" /></a>',
            '<a href="http://www.linkedsite.com/" target="_blank"><img src="myimagesdirectpath/img.png" alt="linkedsitename" /></a>',
            '<a href="http://www.linkedsite.com/" target="_blank"><img src="myimagesdirectpath/img.png" alt="linkedsitename" /></a>'
        );

shuffle($images); // Randomize images array
return '<div class="ad">'.implode('<br />', $images).'</div>';
?>

But to be honest the suggestion is always to read some PHP tutorial like this.

After finding a nice introductory course to PHP (Google "php tutorial -w3schools" for a good tutorial on PHP).

Take a look at http://www.php.net/manual/en/function.shuffle.php

Google can tell you how to put your values in an array and neatly output that array using a foreach loop.
