What is the purpose of the Scope-Operator "::" in PHP and how is it typically used?

The Scope-Operator "::" in PHP is used to access static properties and methods of a class without needing to instantiate an object of that class. It is typically used to call static methods or access static properties within a class. Example: 

class MyClass {
    public static $myProperty = "Hello";
    
    public static function myMethod() {
        return "World";
    }
}

echo MyClass::$myProperty; // Output: Hello
echo MyClass::myMethod(); // Output: World
