load custom config from root?

[eluser]rossmurphy[/eluser]
So i tried the include method. I have this in my config file.

Code:

include "./config/config_common.php";

It points to a config dir in the root directory.

In that file i have..

Code:

$config['site_api_url']    = 'bla';
$config['parvor_key'] = 'bla';
$config['site_id'] = 'bla';

But for some reason, the values are no being loaded into the config array.
