I have a hard-coded menu in Drupal (as it's too complex for the standard Menu system in Drupal).

I would like to be able to say: If this page is contained within the /about/ directory, apply the class "active", so that all new pages created within this directory automatically highlight the current section.

Currently I have:

```
$current_page = $_SERVER['REQUEST_URI'];

<ul class="main">
  <li class="home"><a href="<?php echo $base_path?>">Home</a></li>
  <li class="about 
  <?php if ($current_page == "/xxxxxxx.com/dev/about/") 
  {
      echo "active";
  }
  ?>"><a href="javascript:void(0)">About</a></li>
  <li class="services"><a href="javascript:void(0)">Services</a></li>
  <li class="work"><a href="javascript:void(0)">Work</a></li>
  <li class="awards"><a href="javascript:void(0)">Awards</a></li>
  <li class="environment"><a href="javascript:void(0)">Environment</a></li>
  <li class="contact"><a href="javascript:void(0)">Contact</a></li>
</ul>

```

I have tried a few variations of strpos and explode to get the right variable, but with no luck so far.

Thanks :)
