How to use PHP7.0 to implement an online music player?

With the popularity of the Internet and mobile devices, the spread and playback of music continues to increase. More and more websites and applications are also beginning to provide online music playback functions. This article will introduce how to use PHP7.0 to implement a simple online music player.

1. Environment preparation

First, you need to install PHP7.0 or above locally or on the server. In addition, we also need a MySQL database to store music file information (such as file name, path, play times, etc.).

2. Create a file server

We need to create a file server to store music files. This can be achieved using server software such as Apache or Nginx. On the file server, you need to create a directory to store music files, such as "/var/www/html/music".

3. Upload of music files

Through the Web interface, users can upload music files. When uploading files, we need to check the file type (such as MP3, WAV, etc.) and move the music files to the music directory. At the same time, we also need to store music file information in the MySQL database.

4. Preparation of playback page

Create an HTML page to display the online music player. Query the MySQL database through PHP to obtain music file information (such as file name, path, play times, etc.), and present the data on the page. On the page, we need to add player controls (such as play, pause, forward, back, etc. buttons).

5. Control the behavior of the player

On the play page, we need to control the behavior of the player through JavaScript. For example, when the user clicks the "Play" button, a request needs to be sent to the server to obtain the music file and the file is passed to the player for playback. At the same time, we also need to record the number of times each music file is played and refresh it on the page in real time.

6. Implement the search function

In order to facilitate users to find music, we need to implement the search function. Users can search for music files by keywords and the results will be displayed on the page.

Summary

Through the above steps, we can use PHP7.0 to implement a simple online music player. Of course, this is just a base version. If you want to implement more complex functions, such as lyrics display, song recommendation, etc., you need to add corresponding code.

Finally, I hope this article can help developers who want to learn PHP music player.
