PHP MVC Dependency Injection

This project is a basic web application template in PHP following the Model-View-Controller (MVC) design pattern and extensively applying the Dependency Injection Pattern.

The MVC design pattern combined with dependency injection is an excellent combination in PHP projects. The Model-View-Controller pattern separates responsibilities between business logic (Model), user interface (View), and application flow control (Controller). Dependency injection helps avoid spaghetti code, improving code scalability and maintenance. Additionally, this project includes a service layer to handle business logic, similar to how projects are structured in Spring.
