How do you create class methods? How do you call object methods? (See pages 121 and 124.)
How do you create class attributes? How do you reference those attributes within the class? How do you reference those attributes using an object? (See pages 121, 124, and 127.)
What is a constructor? How do you create one? When is a constructor called? (See page 133.)
What is a destructor? How do you create one? When is a destructor called? (See page 136.)
What is UML? How do you represent a class in UML? (See page 140.)
What is phpDocumentor? What are the arguments for using it? (See page 143.)

Learn more about UML, if you are so inclined.
Find UML software that you like (for your platform or online).
Learn more about phpDocumentor, if you are so inclined.
Add phpDocumentor-style comments to the Rectangle class and then generate its documentation.
