How to quickly build the WeChat mini program mall backend with PHP

With the rise of WeChat mini programs, more and more companies are beginning to pay attention to and develop WeChat mini program businesses, especially mini program malls. As the backend development tool for mini program malls, PHP is both free and open source and can help companies quickly build the backend of WeChat mini program malls. This article introduces how to use PHP to quickly build the backend of a WeChat mini program mall.

1. Preparation work
Before starting to build, we need to prepare the following tools:

1. PHP operating environment;
2. MySQL database;
3. WeChat applet AppID and AppSecret.

Among them, the installation and construction of the PHP running environment and MySQL database will not be described in detail here.

2. Download code
We can choose the WeChat mini program mall open source code on Github to download. The Github address is:
https://github.com/EastWorld/wechat-app-mall

After the download is completed, we can enter the root directory of the code, which has the following three important directories:

1. backend: background code;
2. frontent: front-end code ;
3. database: database script.

3. Configuration files
Before starting to use the code, we need to modify some configuration files according to our actual situation. The following are the files that need to be modified.

1. backend pplicationextra pi.php
   This file is the API configuration file. We need to modify the database configuration, WeChat applet AppID and AppSecret configuration according to our actual situation.
2. backend applicationdatabase.php
   This file is the database configuration file. We need to modify the database host, port, user name and password configuration according to our actual situation.
3. frontendsrcutilsconfig.js
   This file is the front-end configuration file. We need to modify the API interface address and other configurations according to our actual situation.

4. Import the database
There are two SQL files in the database directory in the code. We need to create a database first, and then import these two SQL files into the database.

5. Start the background service
We can use the command line to enter the backend directory, and then use the following command to start the background service:
php think run

6. Deploy the front-end code
We need to use the following command to install dependencies in the frontend directory:
npm install

After the installation is complete, we can use the following command to start the front-end service:
npm run dev

7 , WeChat applet configuration
We need to configure the server configuration and development settings on the WeChat public platform, where the address of the backend interface needs to be filled in in the server configuration.

8. Test
At this point, we have completed the construction of the backend of the WeChat mini program mall and can test it in the WeChat developer tools.

Summary
Through the above steps, we can use PHP to quickly build the backend of the WeChat mini program mall. It has low development cost, high efficiency and strong flexibility. It is the best choice for developing WeChat mini program mall business.
