An alternative to globals

I have a set of variables that should be available on my site. Although I could declare them in my header.php file, I would prefer to define them in functions.php or just not in the template file (view). All that I read says DO NOT USE GLOBAL ... excellent. But what is the best way to define these variables?

Here is what I want to determine:

 global $favorites_array;
 global $user;
 global $user_id;
 global $user_name;
 global $uri;

 $user = wp_get_current_user();
 $user_name = $user->user_login;
 $user_id = $user->ID;
 $user_id = get_current_user_id();
 $uri = $_SERVER['REQUEST_URI'];
