How to develop WeChat public account in PHP?

With the development and popularity of mobile Internet, WeChat has become an important social platform and mobile application. Therefore, many companies and organizations have begun to use WeChat official accounts to promote their products and services. The PHP language is a programming language widely used in Web development, so WeChat public account development in PHP is also a common choice. This article will introduce how to develop WeChat public accounts in PHP.

1. Register WeChat public account

Before starting the development of WeChat public account, we need to register a WeChat public account first. You can go to the WeChat public platform to register and choose different public account types according to your needs. It should be noted that the development of WeChat public accounts requires WeChat public account certification, otherwise it will be subject to many restrictions. Therefore, it is recommended to perform identity authentication before registering a WeChat official account.

2. Obtain WeChat public account development permissions

After registering the WeChat public account, we need to obtain the permissions required for WeChat public account development. Specifically include:

• Perform developer authentication
• Get developer ID and password
• Get developer Token

## Develop the WeChat public account function

After obtaining the WeChat public account development permission, we can start to develop the WeChat public account function. Specifically, we can complete the development of the WeChat public account function through the following steps:

Enter Token and verification information: When starting to develop the WeChat public account, we need to enter a Token and verify message. Token is a credential used to verify the developer's identity. The verification information is a string used to check and confirm whether the received information comes from the WeChat server. This information is usually obtained in the first step of WeChat official account development.
• Receive and process messages: In the development of WeChat public accounts, we need to receive and process messages entered by users. By calling the WeChat official account interface, we can obtain the user's text messages, image messages, voice messages and other types of messages. We then need to parse and process these messages and return appropriate response messages based on the message type.
• Send template messages: In addition to receiving and processing messages, we can also send template messages through the WeChat public account interface. Template messages are messages that can be automatically pushed to users, and are suitable for scenarios such as notifications and appointments. We need to set the template content by calling the interface and select the target users to push to. It should be noted that sending template messages requires WeChat official account authentication before it can be used.
• Develop custom menus: In the development of WeChat public accounts, we can also develop custom menus for users to make it easier for users to access the functions they want. Specifically, in menu development, we can set the name of the menu, URL link, event handler, etc. Then, the menu is sent to the WeChat server and the menu will be displayed in the user's WeChat.

Deploy and test the WeChat public account

After completing the development of the WeChat public account, we need to deploy it to the server and test it to ensure It performs the intended function. Specifically, we need to upload the code to the web server and log in to the WeChat official account backend for configuration. Then, use the WeChat test account or follow the official account to test whether the official account functions normally.

Summary

In this article, we introduced the basic steps for WeChat public account development in PHP. We need to register a WeChat official account and obtain relevant development permissions, and then write code to implement functions such as receiving and processing messages, sending template messages, and developing custom menus. Finally, we need to deploy the code to the web server and test it to ensure that the WeChat official account function can work properly.
