PHP MVC (Model-View-Controller) Architecture

PHP MVC (Model-View-Controller) Architecture is a design pattern commonly used in web development to separate the concerns of an application into three distinct components: Model, View, and Controller. This architectural pattern helps in organizing and maintaining code in a structured and maintainable manner.


Here's an explanation of each component and examples of popular PHP frameworks that implement MVC :
  1. Model :
    • The Model represents the application's data and business logic. It interacts with the database or other data sources, performs data manipulation, and enforces business rules. It also provides data to the View for presentation.
    • Example: In a content management system (CMS), the Model could be responsible for handling user accounts, managing content, and storing data in a database.
  2. View :
    • The View is responsible for rendering the user interface and presenting data to the user. It receives information from the Controller and displays it in a user-friendly format, such as HTML, XML, or JSON.
    • Example: In a web application, the View could consist of templates, HTML, and CSS files that define how the content should be presented to the user.
  3. Controller :
    • The Controller acts as an intermediary between the Model and the View. It handles user input, processes requests, invokes the appropriate Model components, and decides which View to render. Controllers control the flow of the application.
    • Example: In an e-commerce website, the Controller would manage actions like adding products to a cart, processing payments, and updating inventory. It also determines which page or view to display based on user interactions.
Popular PHP Frameworks Implementing MVC :

Laravel


Symfony


CodeIgniter


These PHP frameworks help developers follow best practices and maintain separation of concerns in their applications, making it easier to develop, test, and maintain complex web applications.
