PHP Object Oriented Programming Concepts

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
