Laravel is an open source web application framework based on PHP. It is widely used in web development, especially for MVC pattern applications. Its good design structure, easy expansion features and good documentation make Laravel an ideal choice for development. One of the web frameworks that readers are happy to use.

The Laravel framework greatly simplifies the process of web application development and provides rich functionality and the tools and libraries needed to build applications. Code written in the Laravel framework has excellent maintainability and readability, which greatly improves developer productivity and team collaboration efficiency.

So, how does the Laravel framework work?

The Laravel framework is a framework based on the MVC design pattern. It mainly consists of four parts:

  1. Router (Route): Responsible for receiving requests and sending responses for Web applications. Provide web pages and API interfaces.
  2. Controller (Controller): responds to requests from the router, processes data and returns the corresponding view (View) or data model (Model).
  3. View: Web interface provided to users, including HTML and CSS styles.
  4. Model: A set of classes that operate and manage data, responsible for retrieving data from databases and other data stores, performing CRUD operations, etc.

These components work together with their respective tasks to build a given web application.

When a user accesses the application, the request will first be received by the router. The router reads the rules in the routing file and assigns the request to the correct controller (Controller) to perform the corresponding task. This controller will handle the request, call the corresponding model (Model) to obtain and/or update the data, and then present the data in the view (View), allowing the application to return a dynamic HTML page or an API returned Data data.

The working principle of Laravel framework is based on some useful features such as dependency injection, routing middleware, template engine, database object relational mapping (ORM) and command line interface. These functions work together to quickly architect web applications and develop efficient API services. Developers can focus on business logic without paying attention to underlying technical details.

In terms of code development, the Laravel framework uses simple, elegant and intuitive syntax, such as Route::get(), View::make() and DB::table(), which can greatly improve Developer productivity. In addition, the Laravel framework uses several useful command line tools such as Artisan to provide a fast development experience.

In short, the Laravel framework is a very popular web application development framework and is widely used among developers. Its working principle is based on the MVC pattern, providing developers with a fast, efficient, maintainable and scalable web application development experience by providing rich functions and useful tools.
