No, it won't.
There is no way to do this automatically in the function definition.
You would have to define an empty default:
function f($var = null) { .... }
and then fill $var with a value from your configuration array inside the method if it is null.

No. What I would do is to add $config as an field to the class, like this:
class MyAwesomeClass {
public $config;
public function f() {
...
}
}
$cls = new MyAwesomeClass;
$cls->config = $GLOBALS['config'];
$cls->f();
