Polymorphism and Flexibility

Polymorphism allows objects of different classes to be treated as objects of a common base type. This principle enables a single interface to represent multiple underlying forms. Polymorphism can be achieved through interface implementation, inheritance, or dynamic method resolution. In practice, it allows developers to write code that operates on general types while supporting diverse behavior in concrete classes. Understanding polymorphism is critical for Zend 200-710 Exam candidates, as it underpins many design patterns and ensures code can adapt to changing requirements without significant refactoring.

Encapsulation and Information Hiding

Encapsulation is the practice of restricting direct access to an object’s internal state and exposing only the necessary operations to interact with it. This protects the integrity of the object and prevents unintended interference or misuse. Proper encapsulation involves defining private or protected properties and providing controlled access through public methods. For advanced PHP applications, encapsulation promotes security, simplifies debugging, and allows developers to refactor internal implementation without affecting external code.

Composition Over Inheritance

While inheritance provides a mechanism to reuse and extend behavior, composition encourages building complex objects by combining simpler, reusable components. Composition offers greater flexibility because it avoids the tight coupling associated with deep inheritance hierarchies. By favoring composition, developers can create modular, maintainable systems that are easier to extend and test. For the Zend 200-710 Exam, understanding the trade-offs between inheritance and composition is essential for designing robust software architectures.

Traits and Code Reusability

Traits in PHP provide a mechanism to share common functionality across classes without relying on multiple inheritance.

Advanced OOP in PHP requires understanding how to leverage traits effectively, manage conflicts, and maintain clarity in class design. Candidates should also be familiar with the limitations of traits and scenarios where interfaces or composition may be more appropriate.

Dependency Injection and Inversion of Control

Dependency injection is a design principle that decouples class dependencies by providing them externally rather than creating them internally. This facilitates greater flexibility, easier testing, and adherence to the inversion of control (IoC) principle. Using dependency injection, classes become more modular, and their interactions are easier to manage, configure, and mock during testing. Candidates should understand the benefits of dependency injection containers and how they contribute to maintainable and scalable applications.

Design Patterns in Advanced OOP

Advanced OOP often involves leveraging established design patterns to solve common problems systematically.

SOLID Principles

The SOLID principles form the foundation of high-quality object-oriented design:

1. Single Responsibility Principle: A class should have one reason to change.

2. Open/Closed Principle: Classes should be open for extension but closed for modification.

3. Liskov Substitution Principle: Derived classes should be substitutable for their base classes.

4. Interface Segregation Principle: No client should be forced to depend on methods it does not use.

5. Dependency Inversion Principle: Depend on abstractions, not concrete implementations.
