How to implement hidden functions of music player through PHP

With the development of the Internet, music players on web pages are becoming more and more common. However, in some occasions, such as blogs and personal websites, we hope that the music player can exist in a form that does not affect the beauty of the page. In this case, it is necessary Use PHP to hide the music player technique. This article will introduce how to hide the music player through PHP and provide relevant code examples.

1. Implementation Ideas

I believe everyone can do it by adding a music player to a web page. Here we mainly introduce how to hide the music player through PHP code. The specific implementation ideas are as follows:

1. First, store the path and name of the music file in an array as parameters for subsequent program calls.
2. Determine whether there is a parameter to pass the music number. If not, the default music number is used. The music number is the array subscript that stores the music name.
3. Based on the path and name of the music file, generate the HTML code corresponding to the music player, and return the code to the calling page.
4. In the web page, the music player can be hidden or displayed by calling the PHP function.

The above is the basic idea of ​​hiding the music player. The specific implementation method will be introduced step by step below.

2. Specific implementation

1. Store the path and name of the music file in the array

In the PHP code, we need to define an array containing the path and name of the music file. Array, the code is as follows:

$music = array(
    0 => array('file'=> './music/song1.mp3', 'name'=> '歌曲1'),
    1 => array('file'=> './music/song2.mp3', 'name'=> '歌曲2'),
    2 => array('file'=> './music/song3.mp3', 'name'=> '歌曲3'),
    3 => array('file'=> './music/song4.mp3', 'name'=> '歌曲4')
);

In the array, our example defines 4 songs. Each item contains a file path and file name. Please modify the file path according to the actual situation.

2. Determine whether there is a parameter to pass the music number

We need to pass a music parameter in the page URL, which is the music number we defined. The code is as follows:

$music_id = isset($_GET['music']) ? intval($_GET['music']) : 0;

In the code, we first determine whether there is a music parameter passed in. If not, the first song will be selected by default.

3. Generate the HTML code corresponding to the music player

According to the path and name of the music file, we need to generate the corresponding HTML code for the music player. The code is as follows:

$play_html = '<audio src="&#39; . $music[$music_id][&#39;file&#39;] . &#39;" controls loop autoplay></audio>';

In this code, we use the audio tag in HTML5 and use PHP functions to splice various parameters of the player. It should be noted that we used the $music_id variable in the HTML code, which is the number of the music that needs to be played.

4. Hide or show the music player

The last step is to hide or show the music player on the page. Here we use a PHP function to determine whether to hide the music player or display the music player based on the parameters passed in. The code is as follows:

function show_play($html,$is_show=true){
    if($is_show == true){
        echo $html;
    }
}

In this function, $html is the music player HTML code we generated, $is_show is a Boolean value, if it is true, the music player is displayed, otherwise it is hidden.

3. Complete code and usage

The above is the PHP implementation method to hide the music player. The complete code and usage instructions are provided below.

Sample code: In the

<?php
$music = array(
    0 => array('file'=> './music/song1.mp3', 'name'=> '歌曲1'),
    1 => array('file'=> './music/song2.mp3', 'name'=> '歌曲2'),
    2 => array('file'=> './music/song3.mp3', 'name'=> '歌曲3'),
    3 => array('file'=> './music/song4.mp3', 'name'=> '歌曲4')
);
$music_id = isset($_GET['music']) ? intval($_GET['music']) : 0;
$play_html = '<audio src="&#39;. $music[$music_id][&#39;file&#39;] .&#39;" controls loop autoplay></audio>';
function show_play($html,$is_show=true){
    if($is_show == true){
        echo $html;
    }
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>PHP隐藏音乐播放器</title>
</head>
<body>
    <div style="text-align:center;">
        <h1>PHP隐藏音乐播放器</h1>
        <h3>选择一首歌曲播放：</h3>
        <ul>
            <?php foreach($music as $k => $v){ ?>
                <li><a href="?music=<?php echo $k;?>"><?php echo $v[&#39;name&#39;];?></a></li>
            <?php } ?>
        </ul>       
    </div>
    <?php show_play($play_html,false); ?>
</body>
</html>

page, we hide the music player by default. If you need to display it, you can call the show_play function in the page and set the second parameter to true. The sample code is as follows:

show_play($play_html,true);

Through the implementation of the above code, we can hide the music player in the web page without affecting the beauty of the page.
