Getting Started with PHP: Separation of Front and Backends

As a very popular programming language, PHP plays an important role in Internet development. As the trend of front-end and back-end separation has become more and more obvious in recent years, more and more PHP developers are also thinking about how to better separate front-end and back-end development. This article will introduce you to the PHP introductory guide and teach you how to separate the front and back ends.

1. The basic concept of front-end and back-end separation

Front-end and front-end separation development refers to separating the front-end and back-end codes. The front-end is responsible for displaying the page and user interaction logic, and the back-end is responsible for processing data logic. and business logic. The benefit of this separation is to improve the maintainability, scalability and reusability of the code, while also supporting multi-end development and providing a better user experience.

2. Front-end and back-end communication methods

In the front-end and back-end separation development, communication needs to be carried out between the front and back ends. The communication methods generally include the following:

(1) RESTful API: Using HTTP protocol for communication, RESTful API can completely separate requests and responses, support cross-platform, cross-language, and is simple and easy to use. It is now the most popular front-end and back-end communication method.

(2) WebSocket: uses a full-duplex communication protocol, which is more efficient than the traditional HTTP protocol. It is suitable for real-time communication scenarios and is not suitable for one-way communication situations.

(3) GraphQL: It is a self-describing, strongly typed, hierarchical-based query language. Compared with RESTful API, GraphQL can improve API performance and development efficiency.

3. PHP development framework selection

In front-end and back-end separation development, it is very important to choose a suitable PHP development framework. The following are several commonly used PHP development frameworks:

(1) Laravel: It is a PHP development framework with elegance, simplicity and reusability as its core. It supports RESTful API development, automatic document generation and other functions, which is very suitable for Small and medium-sized projects.

(2) Symfony: Another popular PHP development framework, it provides a rich set of components and libraries and is a very stable and mature framework.

(3) YII: It is a high-performance PHP development framework, suitable for projects that require high concurrent processing capabilities, but the learning curve is relatively steep.

Different PHP frameworks are suitable for different development situations. You need to carefully analyze the requirements and business scenarios to choose the PHP development framework that best suits your project.

4. Front-end and back-end separation development tools

In front-end and back-end separation development, using some tools can greatly improve development efficiency. The following are several commonly used tools:

(1) Postman: It is an excellent API testing tool that supports multiple functions such as request simulation, interface testing, and test automation.

(2) VS Code: It is an open source cross-platform editor that supports rich plug-ins and extension functions and is very suitable for PHP development.

(3) Chrome DevTools: It is a set of development and debugging tools for web developers, which is very practical in front-end development and debugging.

Summary: The above is the PHP introductory guide of this article, which introduces the basic concepts of front-end and back-end separation development, front-end and back-end communication methods, PHP development framework selection, and front-end and front-end separation development tools. I hope readers can better carry out front-end and back-end separation development and improve development efficiency and code quality.
