Classes also help you keep your code modular — you can define a class in a separate file, and include that file only in the pages where you plan to use the class — and simplify code changes, since you only need to edit a single file to add new functionality to all your spawned objects.

These properties and methods of the object correspond directly with the variables and functions within the class definition. A typical class definition contains both variables and functions, and serves as the template from which to spawn specific instances of that class.

This comes in handy in situations where you need to spawn more than one instance of an object — for example, two simultaneous database links for two simultaneous queries, or two shopping carts.

By limiting yourself to exposed methods, you are provided with a level of protection which ensures that changes in the class code do not pythkn repercussions on your code.
