What is the core design of laravel framework

The Laravel framework can be said to be one of the most popular and commonly used development frameworks in web development. It is a popular PHP framework for building high-quality web applications. What's so special about the Laravel framework? What is the core of its design? Let’s explore it together.

1. MVC Architecture

The core design of the Laravel framework is the MVC architecture. MVC stands for Model, View, and Controller, which is a software design pattern. The model is the code that relates to the database data, the view is the code that is displayed to the user, and the controller is the code that connects the model and the view. By splitting application code into these three components, Laravel makes it easier to maintain and develop applications.

The model part is the code used to manage and process database data. In Laravel, the model is based on Eloquent ORM, a simple yet powerful database manipulation tool. It allows developers to use PHP objects to represent data in the database, making it easier to manage complex relational databases.

View is part of the user interface. In Laravel, views are usually built using the Blade template engine. The Blade template engine allows you to create dynamic HTML pages that contain PHP code, variables, and some control structures, making it easy for developers to combine and reuse views.

The controller is where business logic is handled in the application. The controller can use methods in the model to obtain data and then display that data to the user through the view. Controllers can also handle user input, such as getting data from forms, and perform business logic. Using controllers, developers can better manage the flow of their application, ensuring that the code is easy to maintain and extend.

2. Routing

Laravel also has a powerful routing system. Routing refers to how a web application handles requests from users. In Laravel, routing allows developers to easily define various routes for the application and map them to the corresponding controller methods.

Laravel's routing system is very flexible. It supports HTTP request methods (such as GET, POST, PUT, DELETE, etc.), can match URL parameters, and also supports features such as route grouping, named routes, and routing middleware. These features make it easier for Laravel developers to define complex routing rules to meet different application needs.

3. Artisan command line tool

Laravel also provides a very powerful command line tool-Artisan. Artisan can help developers automatically generate code, generate database migration files, run database migrations, generate tests, automatically generate documentation, and more. The Artisan command line tool greatly simplifies the development and maintenance process of Laravel applications, helping you write code more efficiently and improve code quality.

4. Community Support

Laravel has a very active developer community. This community provides a lot of help and resources. Laravel experts who devote themselves silently often express their opinions, experiences and tutorials in major Laravel exchange communities. There are also many free open source Laravel projects for learning and use, which is extremely convenient. used by developers.

Summary

The design core of the Laravel framework is the MVC architecture, which decomposes the application into models, views and controllers, making Laravel applications easy to maintain and develop. The Laravel framework also has a powerful routing system and Artisan command line tools, both of which can help developers build and maintain Laravel applications more efficiently. Not only that, the increasingly powerful Laravel community also provides developers with a considerable degree of help and support, which will benefit you a lot in learning and applying Laravel development.
