Displaying five random $product while maintaining key => value?

I am trying to include a "You might also be interested in:" section on my site. I am able to shuffle and display the correct number of products that I want. However, I am losing the $product_id and therefore my links are broken.

The code I have tried without success:

<div class="row"> <div class="span12"> <ul id="tiles"> <?php

                    function shuffle_assoc($list) { 
                      if (!is_array($list)) return $list; 

                      $keys = array_keys($list); 
                      shuffle($keys); 
                      $random = array(); 
                      foreach ($keys as $key) { 
                        $random[] = $list[$key]; 
                      }
                      return $random; 
                    }

                    $get_list_view = "";
                    shuffle_assoc($products);
                    $total_products = count($products);
                    $position = 0;
                    foreach($products as $product_id => $product) {
                            $position = $position + 1;
                            if ($position < 6) {
                                    $get_list_view = get_list_view_html($product_id, $product) . $get_list_view;    
                                } else {}
                    }
                    echo "$get_list_view";
                    ?>
                </ul>
            </div>  
        </div>

Any help will be appreciated.

Have you watched the videos in the Refactoring my Codebase course? [http://teamtreehouse.com/library/programming/enhancing-a-simple-php-application/refactoring-the-codebase] The first three deal with this issue. We use automated duplication to put the key inside the array as an attribute, as well, to avoid this exact problem.
