Title: Using WebMan technology to build a professional music playback platform

Foreword:
With the rapid development of the Internet, music has become indispensable in people's lives part. Therefore, building a professional music playback platform has become particularly important. In this article, we will introduce how to use WebMan technology to build a powerful music playback platform, and attach corresponding code examples.

1. Technology Selection and Preparation
Before building a music playback platform, we need to choose the appropriate technology. Here, we choose to use WebMan technology because it is a very powerful and flexible technology that can help us quickly build a professional music playback platform.

Before we start, we need to prepare the following tools and environment:

Web server (such as Apache, Nginx, etc.)
PHP programming language
MySQL database
HTML, CSS and JavaScript technology

2. Database design
When building a music playback platform, the core data storage and management work is completed by the database. The following is a simple database design example:

Table: Users table (users)
Field:
- id (user ID)
- username (username)
- password (password)
- email (email)
Table: song list (songs )
Field:
- id (song ID)
- title (song title)
- artist (song artist)
- album ( The album the song belongs to)
- file_path (song file path)
Table: playlists (playlists)
Field:
- id (playlist ID)
- user_id (user ID)
- name (playlist name)
Table: Playlist Songs (playlist_songs)
Field:
- id (playlist song ID)
- playlist_id (playlist ID)
- song_id (song ID)

3. Build the user interface
Next, we will build a user-friendly front-end interface. In this example, we will use HTML, CSS and JavaScript to achieve this.

HTML code example:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>音乐播放平台</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <h1>音乐播放平台</h1>
    <div id="playlist">
        <h2>我的播放列表</h2>
        <ul id="playlist-items">
            <!-- 此处填充播放列表 -->
        </ul>
    </div>
    <div id="songs">
        <h2>歌曲列表</h2>
        <ul id="song-items">
            <!-- 此处填充歌曲列表 -->
        </ul>
    </div>
    <script src="script.js"></script>
</body>
</html>

CSS code example (style.css):

/* 样式表示例 */

body {
    font-family: Arial, sans-serif;
}

h1, h2 {
    color: #333;
}

#playlist, #songs {
    margin-bottom: 20px;
}

#playlist-items li, #song-items li {
    cursor: pointer;
    margin-bottom: 10px;
}

Copy after login

JavaScript code example (script.js):

// JavaScript代码示例

document.addEventListener("DOMContentLoaded", function() {
    // 获取并填充播放列表
    var playlistItems = document.getElementById("playlist-items");
    // TODO: 通过Ajax请求获取播放列表数据并填充

    // 获取并填充歌曲列表
    var songItems = document.getElementById("song-items");
    // TODO: 通过Ajax请求获取歌曲列表数据并填充

    // 添加点击事件监听器
    playlistItems.addEventListener("click", function(e) {
        // TODO: 根据所点击的播放列表项来切换歌曲播放
    });

    songItems.addEventListener("click", function(e) {
        // TODO: 根据所点击的歌曲项来添加到当前播放列表
    });
});

four ,Building back-end logic
Through the PHP programming language and MySQL database, we can build the back-end logic. The following is a simple PHP code example:

<?php
// 数据库连接配置
$host = "localhost";
$username = "root";
$password = "password";
$dbname = "music_platform";

$conn = new mysqli($host, $username, $password, $dbname);

if ($conn->connect_error) {
    die("数据库连接失败：" . $conn->connect_error);
}

// 获取播放列表数据
$playlists = [];
$sql = "SELECT id, name FROM playlists";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        $playlists[] = $row;
    }
}

// 获取歌曲列表数据
$songs = [];
$sql = "SELECT id, title, artist, album, file_path FROM songs";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        $songs[] = $row;
    }
}

// 返回数据
$data = [
    'playlists' => $playlists,
    'songs' => $songs
];

header('Content-Type: application/json');
echo json_encode($data);
?>

5. Summary
By using WebMan technology, we can easily build a powerful music playback platform. In this article, we introduce the steps of technology selection and preparation, database design, user interface construction, and back-end logic construction, and provide relevant code examples. We hope that these examples can help readers better understand and use WebMan technology to build a professional music playback platform.
