PHP MVC (Model-View-Controller) Architecture

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.

• Laravel is a modern PHP framework that follows the MVC pattern and offers a wide range of features and tools for web application development. It provides an elegant syntax, an ORM (Eloquent), routing, authentication, and more.
• Example: In a Laravel application, you define Models to represent database tables, create Controllers to handle HTTP requests, and use Blade templates for Views.

• Symfony is a robust PHP framework known for its flexibility and scalability. It follows the MVC architectural pattern and provides reusable components and a well-structured architecture.
• Example: In Symfony, you create Controllers to manage routes and logic, use Doctrine as an ORM for data manipulation in the Model, and implement Twig templates for the View.

• CodeIgniter is a lightweight PHP framework that also adheres to the MVC pattern. It offers simplicity and speed for small to medium-sized projects and is easy to learn.
• Example: In CodeIgniter, you create Models for data handling, Controllers to process user requests, and Views to display the output in HTML or other formats.

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.
