With the development of the Internet, music has become an indispensable part of people's lives. In order to meet users' needs for music, it is very necessary to develop a simple music player. This article will introduce how to use PHP to develop a simple music player and provide specific code examples.

<!DOCTYPE html>

<body>
    <h1>简单音乐播放器</h1>
    <div class="music-player">
        <audio id="player" controls></audio>
        <ul id="playlist">
            <?php
                // 遍历音乐目录，生成音乐列表项
                $musicDir = "./music";
                $files = scandir($musicDir);
                foreach ($files as $file) {
                    // 排除.和..
                    if ($file != "." && $file != "..") {
                        echo "<li><a href="music/{$file}">{$file}</a></li>";
                    }
                }
            ?>
        </ul>
    </div>

In the above code, we use the HTML <audio> tag to play music, <ul> and <li> tag is used to display the music list. PHP's scandir() function is used to traverse the music directory and generate music list items.

.music-player {
    width: 300px;
    margin: 20px auto;
}

#playlist {
    list-style: none;
    padding: 0;
}

#playlist li {
    margin: 5px 0;
}

#playlist li a {
    text-decoration: none;
    color: #333;
}

#playlist li a:hover {
    color: blue;
}

The above code controls the style of the music player by setting the width and center alignment of the .music-player class and setting #playlist and #playlist li styles to control the display effect of the music list.

window.onload = function() {
    var player = document.getElementById("player");
    var playlist = document.getElementById("playlist");
    var links = playlist.getElementsByTagName("a");
    
    // 点击音乐列表项时，切换音乐播放
    for(var i = 0; i < links.length; i++) {
        links[i].onclick = function() {
            var file = this.getAttribute("href");
            player.src = file;
            player.play();
            return false;
        };
    }
};

The above code adds a click event listener to each music list item to switch music playback when clicked. Among them, the getAttribute() method is used to obtain the path of the music file, and the play() method is used to play music.
