I'm using this piece of code below to highlight the "active" menu item on my global navigation.

<?php
    $path = $_SERVER['PHP_SELF'];
    $page = basename($path);
    $page = basename($path, '.php');
?>

<ul id="nav">
    <li class="home"><a href="index.php">Home</a></li>
    <li <?php if ($page == 'search') { ?>class="active"<?php } ?>><a href="#">Search</a></li>
    <li <?php if ($page == 'help') { ?>class="active"<?php } ?>><a href="help.php">Help</a></li>
</ul>

All works great but, on a couple of pages, I have a second sub menu (sidebar menu) within a global page.

I basically need to add a OR type statement into the php somehow, but I haven't a clue a how.

Example of what i mean:

    <li <?php if ($page == 'help') OR ($page == 'help-overview') OR ($page == 'help-cat-1') { ?>class="active"<?php } ?>><a href="#">Search</a></li>

Thanks!
