更改 MP3 文件的 ID3 标签

Question

我最近发现了一个网站，它允许您上传文件并更改其 ID3 标记（图片、标题、所有其他内容 )，目前我将文件从另一个网站解析后存储在一个目录中，然后再将它们推送到外部。

我想知道是否有人知道一个库，我可以在其中阅读如何更改 PHP 中的默认 ID3 标记？这是 PHP 的现有功能吗？

if( writeTags($row['title'],$new) ) { 
    $fileName = rand(000000000,999999999).'_'.rand(0000000000,9999999999).'_'.rand(000000000,999999999).'.mp3';
    $imageName = rand(000000000,999999999).'_'.rand(0000000000,9999999999).'_'.rand(000000000,999999999).'.jpg';
    rename($new, $DPATH.'uploads/tracks/'.$fileName);
    save_image($row['image'],$DPATH.'uploads/media/'.$imageName);
    $track['uid'] = 151;
    $track['title'] = $row['title'];
    $track['description'] = '';
    # fileName
    $track['name'] = $fileName;
    # make tag
    $track['tag'] = $tag.',';
    # download image
    $track['art'] = $imageName;
    # today date
    $track['release'] = date("Y-m-d");
    $track['size'] = filesize($DPATH.'uploads/tracks/'.$fileName);

    $row['slippery_id'] = add_to_slippery($track);
}

    function writeTags($title,$file) { 
    $TextEncoding = 'UTF-8';
    require_once($DPATH.'cron/getid3/getid3.php');
    $getID3 = new getID3;
    $getID3->setOption(array('encoding'=>$TextEncoding));
    require_once($DPATH.'cron/getid3/write.php');
    $tagwriter = new getid3_writetags;
    $tagwriter->filename = $file;
    $tagwriter->tagformats = array('id3v1','id3v2.3');
    $tagwriter->overwrite_tags = true;
    $tagwriter->tag_encoding = $TextEncoding;
    $tagwriter->remove_other_tags = true;
    $TagData = array(
       'album'         => array($MP3TAG),
       'comment'       => array($MP3TAG),
    );
    $fd = fopen($DPATH.'cron/mp3image.png', 'rb');
    $APICdata = fread($fd, filesize($DPATH.'cron/mp3image.png')); 
    fclose($fd); 
    $TagData['attached_picture'][0]['data']          = $APICdata;
    $TagData['attached_picture'][0]['picturetypeid'] = 2; 
    $TagData['attached_picture'][0]['description']   = $MP3TAG; 
    $TagData['attached_picture'][0]['mime']          = 'image/jpeg'; 
    $tagwriter->tag_data = $TagData;

    if ($tagwriter->WriteTags()) {
        return true;
    } else {
        return false;
    }
}

我最近做了类似的事情，您可以编辑上面的代码以满足您的要求，如果您希望我提供更多帮助，您应该在您的问题中提供您自己的代码。

请注意，提出这样的问题通常会导致您的问题被关闭，祝您未来好运，我希望这对您有所帮助。

Answer 2

我最近为 eyeD3 制作了一个 PHP 包装器，这是一个用于读取和更新 ID3 元数据的出色 Python 模块。看看here。
如果您熟悉 Composer，则使用非常简单。但是，您需要install eyed3 才能使用它。那么：

1. 使用 composer 安装 php 包装器：

   composer require stormiix/php-eyed3 dev-master
   

2. 将库添加到您的代码中：

   require __DIR__ . '/vendor/autoload.php';
   

3. 使用以下代码读取和更新标签。
   

   use Stormiix\EyeD3\EyeD3;
   
   $eyed3 = new EyeD3("mp3 file path");
   $tags = $eyed3->readMeta();
   // $tags is an array that contains the following keys:
   // artist, title, album, comment(s), lyrics ..etc
   
   $meta = [
       "artist" => "MyArtist",
       "title" => "MyTitle",
       "album" => "MyAlbum",
       "comment" => "MyComment",
       "lyrics" => "MyLyrics",
       "album_art" => "cover.png"
   ];
   // Update the mp3 file with the new meta tags
   $eyed3->updateMeta($meta);
