Single Responsibility Principle (SRP) Open/Closed Principle (OCP) Liskov Substitution Principle (LSP) Interface Segregation Principle (ISP) Dependency Inversion Principle (DIP) Single Responsibility Principle (SRP) Suppose you are building a web application that allows users to sign up and log in to their accounts. To handle user authentication, you might create a class called Authenticator that has the following responsibilities: Validate the user's login credentials.Generate a session token if the credentials are valid.Store the session token in a cookie.Redirect the user to the appropriate page.However, this class violates SRP ...

As a PHP developer, you can benefit from using SOLID principles to write better, more maintainable code. SOLID stands for: Single Responsibility Principle (SRP) Open/Closed Principle (OCP) Liskov Substitution Principle (LSP)Interface Segregation Principle (ISP) Dependency Inversion Principle (DIP) Here's a brief explanation of each principle and how they can be applied in PHP development: Single Responsibility Principle (SRP) This principle states that a class should have only one responsibility.
