What is MVC architecture?
The Model-View-Controller (MVC) architecture is a design pattern commonly used in PHP and other web development frameworks to structure and organize web applications. MVC separates an application into three interconnected components, each with a specific role:
- Model:
– The Model represents the application’s data and business logic. It deals with data storage, retrieval, and manipulation. In PHP, the Model is often responsible for interacting with databases, fetching data, performing calculations, and enforcing application rules.
- View:
– The View is responsible for the presentation layer of the application. It handles the user interface and how data is displayed to users. In PHP, the View typically includes HTML templates, CSS stylesheets, and frontend logic. It receives data from the Model and renders it for the user to see.
- Controller:
– The Controller acts as an intermediary between the Model and the View. It receives user requests, processes them, and determines which actions to take. In PHP, the Controller captures user input, interacts with the Model to fetch or update data, and selects the appropriate View to display the results. It plays a pivotal role in routing and managing application flow.
MVC architecture promotes the separation of concerns, making applications more maintainable, scalable, and testable. It allows developers to work on specific components independently, which enhances code reusability and collaboration. PHP frameworks like Laravel, Symfony, and Yii are built on the MVC pattern, providing developers with a structured and efficient way to develop web applications. By adhering to MVC principles, PHP developers can create organized, modular, and robust web applications that are easier to maintain and extend.
