This repository demonstrates the implementation of SOLID principles in PHP, providing clear examples for each principle. The SOLID principles are a set of five design principles that aim to make software design more understandable, flexible, and maintainable.
SOLID is an acronym that represents five design principles for writing maintainable and scalable software. These principles were introduced by Robert C. Martin and have become fundamental guidelines for object-oriented design. This repository serves as a practical guide to implementing SOLID principles in PHP with real-world examples.
The SRP states that a class should have only one reason to change. In other words, a class should have only one responsibility.
The OCP suggests that a class should be open for extension but closed for modification. This means that you can add new functionality without altering existing code.
The LSP states that objects of a superclass should be able to replace objects of a subclass without affecting the correctness of the program.
The ISP recommends that a class should not be forced to implement interfaces it does not use. It promotes the creation of smaller, more specific interfaces.
The DIP emphasizes that high-level modules should not depend on low-level modules, but both should depend on abstractions. It also introduces the concept that abstractions should not depend on details, but details should depend on abstractions.
This repository includes practical examples demonstrating the application of each SOLID principle in PHP. Each example is contained within its own directory, providing clear illustrations of how to adhere to the principles.
Clone the repository and explore each example to understand how SOLID principles can be implemented in PHP. Feel free to use the code as a reference or incorporate it into your own projects.
