Welcome to the PHP Design Patterns & SOLID Principles repository! This project is a comprehensive collection of PHP examples demonstrating various design patterns and the SOLID principles.
Design patterns are essential for creating robust, scalable, and maintainable code. They provide general reusable solutions to common problems encountered in software design. Here are some benefits:
- Factory Pattern: Simplifies object creation by centralizing it, making the code more manageable and flexible.
- Specification Pattern: Enhances flexibility by allowing business rules to be combined in various ways.
- Adapter Pattern: Enables incompatible interfaces to work together, promoting reusability.
- Chain of Responsibility Pattern: Decouples request senders from receivers, allowing multiple handlers to process requests flexibly.
- Decorator Pattern: Adds behavior to objects dynamically without altering their structure.
- Observer Pattern: Facilitates communication between objects, ensuring changes in one object trigger updates in others.
- Repository Pattern: Abstracts data access, making it easier to manage and test.
- Strategy Pattern: Defines a family of algorithms, encapsulates each one, and makes them interchangeable.
- Template Method Pattern: Defines the program skeleton in a method, deferring some steps to subclasses.
The SOLID principles are a set of five design principles intended to make software designs more understandable, flexible, and maintainable:
- Single Responsibility Principle (SRP): Ensures a class has only one reason to change, promoting cohesion.
- Open/Closed Principle (OCP): Software entities should be open for extension but closed for modification, enhancing flexibility.
- Liskov Substitution Principle (LSP): Objects of a superclass should be replaceable with objects of a subclass without affecting the correctness, ensuring reliable inheritance.
- Interface Segregation Principle (ISP): Clients should not be forced to depend on interfaces they do not use, promoting decoupling.
- Dependency Inversion Principle (DIP): High-level modules should not depend on low-level modules but on abstractions, fostering modularity.
