Section 3.21. Summary

3.21. Summary

This chapter covered the PHP 5 object model, including the concept of classes and objects, polymorphism, and other important object-oriented concepts and semantics. If you're new to PHP but have written code in object-oriented languages, you will probably not understand how people managed to write object-oriented code until now. If you've written object-oriented code in PHP 4, you were probably just dying for these new features.
