I use constants for this, e.g:
if (!defined('INCLUDE_ROOT')) {
require_once(INCLUDE_ROOT . 'foo/bar/menu.php');


echo "<a href='" . INCLUDE_ROOT . "foo/bar.html'>bar</a>";

I define INCLUDE_ROOT in every file. If a file itself is included in 
another file, then INCLUDE_ROOT is alredy defined in the including file, 
thus it is always correct and I can use it anywhere without any worries.
