#2: Open-Closed Principle (OCP) in PHP, Laravel | SOLID Design Principles

Open-closed Principle (OCP) states "Software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification." This implies that entities should be extendable without altering the class itself. The main idea of this principle is to keep the current code from breaking when you add new features. #Laravel #PHP #LaravelPHP #Qirolab ▶ SOLID design principles Playlist https://www.youtube.com/playlist?list=PL1TrjkMQ8UbWsspx0ABrsWl6ENnLEq9AH ▶ What is SOLID design principles in PHP, Laravel?
