Methods

• An object is a parcel of related data

• Also belonging to the object are methods which are designed to operate on the data

• Only the object's methods need to know how the data is organized

• Object method call syntax:

        $object->method(...);

• This is very similar to:

        method($object, ...);

• The object is implicitly passed to the method

• The method can read or modify the object itself
