global variable

I have made a site where I need to be able to include a file containing an
array of settings in many pages. This array needs to have global scope for
use in and out of functions.

If I do this, I can't access the array inside functions:

include('file_with_array');
global $settings;

function wibble()
{
//can't access the array here unless I pass it in!
}

Does anyone know what I'm doing wrong or how to correct this?
Thanks

function wibble()
{
global $settings;
}

One more option I can think of is using constants:

define('DB_USER', 'foo');
define('DB_PASS', 'woo');

function wibble()
{
echo 'User is ' . DB_USER . ' and pass is ' . DB_PASS;
}

Ah, thank you. The constants turned out to be the best way to do it.
