Honestly, what I think you are doing is correct, that would be the way to include that file relatively.

To debug what you are doing anyway, I did a var_dump on $_SERVER['DOCUMENT_ROOT'] and that returned an empty string, so we have no use for that. So then you are left with:

include("../../config/company.php")

Which will fail, saying: PHP Warning: include(../../config/company.php): failed to open stream: No such file or directory in about/leadership/index.php on line 3 PHP Warning: include(): Failed opening '../../config/company.php' for inclusion (include_path='.:/usr/share/pear:/usr/share/php') in about/leadership/index.php on line 3

When you try to include that file like this however

include('config/company.php');

Treehouse will say you're correct and lets you progress. Which is weird, because the full path would be htdocs/about/leadership/config/company.php . So yeah, beats me!

DOCUMENT_ROOT outputs the doc routes absolute path of the current working directory which the script is being executed in.

Therefore you are appending a string to an absolute path which if you printed the path you are trying to form to the screen it would be something like; /var/www/html/../../company/config.php

That path would cause an error - it's in accessible. If you are trying to access something in the current path you can use either for your scenario:

  • include('myscript.inc') - would look in current directory
    • include('./myscript.inc') - ./ denotes in current directory
    • include($_SERVER["DOCUMENT_ROOT"{ . "Myscript.inc")
