Add array of category IDs to global variable?

Question

I'm wondering how I can add a global variable containing an array of category IDs.

On my site, I have menus and custom loops and every time I want to delete a category of them, I have to access each and add the ID of the category to be deleted.

My idea is to have a variable with these ids.

$excluded = array( 1, 2, 3, 4 );

Can I use the functions.php for this?

Simple solution- use GLOBAL variables..

$GLOBALS['my_categories_list'] = array(1,2,3,4);

then you can everywhere access $GLOBALS['my_categories_list'].
