What does double colon in laravel means

Example :

Auth::guard($guard)->guest()

I dont get what double colon (::) notation means in laravel framework. from http://php.net/manual/en/language.oop5.paamayim-nekudotayim.php I learn that it stand for scope resolution operator to access static, constant and overridden properties or methods of a class. but from laravel I learn that Auth means the alias for class facade so I need an explanation of the example above especially guard(parameter)->guest() means.
I'm still new to php and now learning laravel framework for my back-end.

:: Scope Resolution Operator

:: is called as scope resolution operator (AKA Paamayim Nekudotayim). This operator is used to refer the scope of some block or program context like classes, objects, namespace and etc. For this reference an identifier is used with this operator to access or reproduce the code inside that scope.

Reference

Auth::guard($guard)->guest() : In this line you are using the guard() method of static class Auth. To use the function of a static class we use :: Scope Resolution Operator.

Basically its know as

Scope resolution operator (::)

Simply it is token which allow access to static, constant and overridden properties of method of a class

Example- in laravel we call model like this

User::select('name')->get()->toArray();

You are likely encountering this as a way of accessing a static method or property of a class.

For example:

class Foo
{
    public static function bar()
    {
      return "bar";
    }
}

Foo::bar // access the bar method without instantiating the Foo class.
