php

I have a php file which has a require_once Statement (?) this file is then in included in 2 other php files, one php file is in a sub directory so the layout is like this ("file1" and "file2" include the file "included" which require_onces the "required")#

 L--subfolder1
 | L--file1
 L--subfolder2
 | L--required
 L--file2
 L--included

How can I reference the "required" file from the "included" file so that it will work from both file1 and file2?
