Preserving the Functionality of the Parent Class

Occasionally you want to override the method of a parent class in your child class, but also use some of
the functionality that is in the parent class ’ s method. You can do this by calling the parent class ’ s
overridden method from within the child class ’ s method. To call an overridden method, you write
parent:: before the method name:

parent::someMethod();
