php - Nested array to 3-level unordered list -

i have nested array, , looking turn unordered list:

[2009] => array     (         [show name 1] => array             (                 [0] => class 1                 [1] => class 2             )      )  [2008] => array     (         [show name 2] => array             (                 [0] => class 1                 [1] => class 2             )      ) 

and turn into:

2009     show name 1         class 1         class 2 2008     show name 2         class 1         class 2 

so far have partially managed it, being able show year, after 'array' show name should be:

2012     array     array 2009     array 2008     array 

i made using following:

    <ul>     <?php foreach( $results $year => $shows ): ?>     <li><?= $year ?>       <ul>         <?php foreach( $shows $show ): ?>         <li><?= $show ?></li>         <?php endforeach; ?>       </ul>     </li>     <?php endforeach; ?> </ul> 

---

update

i need grab year_id, show_id, class_id each result, can pass them url. like:

        <ul class="no-bullet">         <?php foreach( $results $year => $shows ): ?>         <li><h2><?= $year ?></h2>           <ul class="no-bullet">             <?php foreach( $shows $show_name => $show ): ?>             <li><h4><?= $show_name ?></h4></li>                  <ul class="no-bullet">                       <?php foreach( $show $class ): ?>                       <li><a href="results.html?year=$yearid&show=$showid&class=$classid"><?= $class ?></a></li>                       <?php endforeach; ?>                  </ul>             <?php endforeach; ?>           </ul>         </li>         <?php endforeach; ?>     </ul> 

however, haven't foggiest start. considered query within foreach loop, figured may quite inefficient?

you need treat $show array , extract part want, this:

<ul>     <?php foreach( $results $year => $shows ): ?>     <li><?= $year ?>       <ul>         <?php foreach( $shows $show_name => $show ): ?>         <li><?= $show_name ?>              <ul>                   <?php foreach( $show $class ): ?>                   <li><?= $class ?></li>                   <?php endforeach; ?>              </ul>         </li>         <?php endforeach; ?>       </ul>     </li>     <?php endforeach; ?> </ul>
