Object-Oriented Principles in PHP

The typical beginner, whether they realize it or not, first learns procedural programming. But, before too long, they level up. Suddenly, an entirely different paradigm is introduced: object-oriented programming. Little do they know that they'll spend years researching and learning exactly what it means to work with objects and messages. In this series, you'll be introduced to the core principles of object-oriented programming in PHP. We'll begin with the basic constructs and work our way up.

• Classes
• Objects
• Inheritance
• Abstract Classes
• Handshakes and Interfaces
• Encapsulation
