I want to make my WP code simpler (there’s some mess within header.php, page.php etc.). So, for example, I want to set something like this global:
$foo = get_option('foo');
So $foo
will work properly used anywhere in page.php, header.php, footer.php, loop.php and also within different theme files linked to functions.php (require_once).
I already know two ways of achieving this, both require editing functions.php:
Global dynamic function
function foo() {
return 'bar';
}
Global constant
define('FOO_BAR', 'directory');
Do I really need to fire a function in multiple places just for one variable? Isn’t it an overkill?

You could also use this function:
set_query_var('foo', $foo);
WP will extract and expose all query variables in every template it loads, so you will be able to access it as $foo
