Laravel is an excellent PHP framework that makes PHP development more elegant and efficient. The Laravel workflow is a very important feature that an excellent framework must have.

Laravel workflow mainly includes the following processes:

  1. Receive request

After Laravel receives the HTTP request, it will first pass the request through the routing system Forwarded to the corresponding controller, the controller will process the request according to specific business logic and return the corresponding view or JSON data.

  1. Processing requests

In the controller, Laravel can perform request pre-processing through middleware, such as authentication, defense against CSRF attacks, etc. The controller can also process input data, including verifying the legality of the input data, formatting the input data, etc.

  1. Building views

Views are part of the Laravel template system, which uses the Blade template engine and can be easily extended and customized. Developers can use the Blade template engine to create flexible, easy-to-maintain views, and Blade supports common template functions such as inheritance, inclusion, and conditional statements, which is very practical.

  1. Processing responses

In the controller, Laravel can generate corresponding responses based on the processing results, such as returning views, JSON data, or redirections. You can use the Response class to implement response generation and processing.

  1. Accessing the database

Laravel provides powerful database access capabilities and can easily perform CRUD operations. Laravel uses Eloquent ORM to access MySQL, PostgreSQL, SQLite and SQL Server databases, and supports advanced database tools such as data migration and data filling.

  1. Handling exceptions

During the process of processing requests, exceptions sometimes occur, possibly because the input data is illegal, the database operation fails, or other reasons. Laravel provides an exception handling mechanism. You can use the try-catch statement to catch and handle exceptions to avoid program crashes.

  1. Providing services

Laravel can provide various services, such as email sending, events, queues, task scheduling, etc. By using a ServiceProvider to define a service, you can give your application more valuable functionality and make the service available throughout your application.

Summary

The above are the main contents of Laravel workflow. Through these processes, developers can quickly build high-quality, easy-to-maintain web applications. Laravel is full of rapid development, scalability and maintainability, allowing developers to focus more on their own business logic processing without having to worry about tedious underlying work.
