How do I go up a level in a doc root?
<p>I have a folder admin that has config.php, admin.php.</p>

<p>I want to get navmenu.php in the includes folder.</p>

<p>How do I go up a level from admin.php then to navmenu.php?</p>

<pre><code>admin
  config.php, admin.php

includes
  navmenu.php
</code></pre>

<p>easy question but I forgot what the name is so i can't seem to google it...</p>
