Question

I’m brand new to php and I’m trying to work with some includes in my site and can’t quite figure out how to make them all work correctly.
My site structure is as follows

/ROOT/
   Config.php
   Index.php
   /ADMINISTRATION/
      Index.php
      mustInclude.php
      /USERS/
         Index.php

If “mustInclude.php” includes “Config.php” and Index.php includes “mustInclude.php” everything works fine, but as soon as I try to include “mustInclude.php” into /USERS/Index.php it breaks because “mustInclude.php” is using a path like include '../config.php'; and that isn’t the same relative path for /USERS/Index.php as for /ADMINISTRATION/Index.php

I’m not really sure what to do here.

This is on my local machine for now. Using $_SERVER['DOCUMENT_ROOT'] gives me errors because it outputs my file structure (/Users/James/Sites) rather than my web structure (http://localhost/mysite)

Help?

IMO the best way to include files from anywhere in your application directory structure is to add the root folder of your app to your PHP include path:

<?php
set_include_path(get_include_path().PATH_SEPARATOR."/Users/James/Sites/app_name");

Then, just include files using their paths relative to the application root folder, for example:

<?php
require_once('ADMINISTRATION/USERS/Index.php');
