This course dives into Object-Oriented Programming (OOP) principles within the context of PHP, a popular server-side scripting language. It emphasizes the fundamentals of OOP, including classes, objects, methods, properties, and the four main pillars: encapsulation, abstraction, inheritance, and polymorphism. Participants learn how to structure PHP code using objects to enhance reusability and maintainability, creating modular applications. The course also covers advanced OOP concepts such as interfaces, traits, and namespaces. Through practical examples, learners understand how to apply OOP concepts in PHP to solve complex programming challenges, leading to more efficient and scalable codebases. The focus is on writing PHP code that adheres to OOP principles for robust and secure web application development.
