Introduction
Starting with PHP 5, the object model was rewritten to allow for better performance and more features. This was a major change from PHP 4. PHP 5 has a full object model.
Among the features in PHP 5 are the inclusions of visibility, abstract and final classes and methods, additional magic methods, interfaces, cloning and typehinting.
PHP treats objects in the same way as references or handles, meaning that each variable contains an object reference rather than a copy of the entire object. See Objects and References

Коментарии
Object and classes in php5 is the most powerful and efficient way to organize your code logically, easier to update and understand. it's based on the real world examples.But sometimes its better to think like an electronic digital device rather than a real world equivalent and program using the best logic for performance as well as simplicity. Objects and Classes are usually best, but not always.
