PHP implements music controller skills in WeChat applet

With the popularity of WeChat mini programs, more and more developers are beginning to pay attention to and use the technology of WeChat mini programs. In the development of WeChat mini programs, music playback is a very important function. In this article, we will introduce how to use PHP language to implement music controller skills in WeChat applet.

1. Prerequisites

Before starting to learn PHP to implement the music controller in the WeChat applet, we need to understand the following prerequisites:

1. WeChat Mini Program Development Tool - used to develop and debug WeChat Mini Programs.
2. PHP development environment - used to write PHP scripts to upload and download music files.
3. Server environment - used to store music files and PHP scripts.

2. Implementation of music playback controller

Before implementing the music playback controller, we need to upload music files to the server first. Uploading music files can be achieved using the file upload function in PHP. The following is a simple PHP example of music upload:

After the music file is successfully uploaded, we can use the file reading function in PHP to store the file path in an array, so that when traversing the music list , the PHP code can play music files based on the music paths in the array. The following is a simple example of PHP reading a music file list:

Next, we can use the API interface of the WeChat applet to implement control functions such as music playback, pause, and stop. The following is an example of a music playback controller based on the WeChat applet API:

In the above code, we request to obtain the music file list through the wx.request function, and then use the wx.playBackgroundAudio function in the play function to play the third A music file, while updating the status of the music playback controller in the success callback function, and then calling the corresponding WeChat applet API in the pause and stop functions to implement the function of pausing and stopping the music.

3. Conclusion

This article introduces how to use PHP language to implement music controller skills in WeChat applet. By uploading music files to the server, reading the music file list, and calling the WeChat applet API to implement music playback, pause, stop and other control functions, developers can easily implement a complete music playback controller.
