How do I go up a level in a doc root?

Question

I have a folder admin that has config.php, admin.php.

I want to get navmenu.php in the includes folder.

How do I go up a level from admin.php then to navmenu.php?

admin
  config.php, admin.php

includes
  navmenu.php

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

Answer 1

Try this:

include ("../navmenu.php");

../ means one level back, ../../ means two levels back, ../../../ means three levels back and so on.

Answer 2

.. changes the directory to upper directory.
