What the hell is laravel?

Laravel is an open source PHP web application framework founded by Taylor Otwell in 2011. It is a framework with concise and elegant syntax and powerful functions. It provides functions such as routing, template engine, Eloquent ORM, middleware and other functions. With the help of Laravel, web application development becomes faster and more convenient, and has the advantages of scalability, maintainability, testability and other advantages. During the development of Laravel, many component packages have been widely used, and in terms of package management, it introduced Composer and became a truly modern PHP framework.

The full name of Laravel is "Laravel PHP Framework", and the name "Laravel" comes from the French word "Lavarel", which means "metal craftsman". The inspiration for this name comes from the author's trip to France, and the fact that the Laravel framework can provide a process similar to metal processing for the project, so it became the current name.

Laravel's design philosophy is to be developer-friendly and avoid duplication of work. It provides many convenient features, the most important of which are routing and controllers. For a web application, routing is very critical because it connects requests and responses. Without routing, a web application would be impossible. In Laravel, routing defines how a URL should be processed, and middleware can also be configured for the corresponding URL, such as logging middleware, authorization middleware, etc. The controller is one of the components of the MVC framework in Laravel, and the view and model are the other two parts. Laravel's controller is extended from a base controller class. In order to avoid writing a lot of repeated code, it provides many convenient functions, such as request input verification, CSRF protection, automatic translation, event scheduling, etc. Laravel's front-end template engine uses Blade, which can be used to quickly and easily create rendering logic and templates.

At the model level, Laravel provides Eloquent ORM, which is a powerful and flexible ORM that provides many functions, such as relationship mapping, accessors, modifiers, etc. In addition, Laravel introduces the concept of migration, which can modify the structure of the database by managing database migration.

Laravel's middleware implements the concept of aspect-oriented programming, providing developers with a way to write reusable code that can be used to handle HTTP requests and responses as well as routing access control. This approach can more clearly encapsulate the behaviors that belong to specific routes or controllers into middleware, making the code more modular.

A web application may involve issues such as security, performance, caching, etc., which can all be achieved through Laravel's various features. Laravel provides a series of auxiliary functions, classes, and features that can help developers perform a variety of tasks, such as database processing, email sending, file system, caching, request and verification, Cookie and Session, etc. Laravel handles security aspects uniquely, such as CSRF, XSS protection, authentication and authorization, etc., making web applications more robust and reliable.

In addition to the above features, Laravel also has many practical components and extension packages available, such as Horizon, which is an excellent queue manager. Many communities and organizations are now using it. Through Horizon, We can create, view, and manage message queue tasks, which greatly improves the performance and scalability of web applications. Another example is Scout, which provides a simple search framework that can be used for a variety of content, such as emails, articles, content, etc., which is very practical.

In short, Laravel is a powerful PHP framework that has been committed to bringing developers a better development experience for many years. Its speed, readability, scalability and ease of use make it the preferred framework in PHP development today, and it is widely and actively used in web application development and maintenance around the world.
