我正在寻找使用 PHP 设置 mp3 专辑封面的最佳方式或任何方式。
建议?
专辑封面是由于 ID3v2 规范而被标识为“附加图片”的数据帧,而 getID3() 现在只是使用纯 PHP 在 ID3v2 中写入所有可能的数据帧的一种方法。
看看这个来源: http: //getid3.sourceforge.net/source/write.id3v2.phps
在源代码中搜索此文本:
// 4.14 APIC Attached picture
有一段代码负责编写专辑封面。
另一种似乎不像纯PHP那么慢的方法是使用一些外部应用程序,该应用程序将由PHP脚本启动。如果您的服务设计为在高负载下工作,二进制编译工具将是一个更好的解决方案。
更好(更快)的方法是通过外部应用程序和 PHP exec() 函数来执行命令。我会推荐eyeD3。
不确定这仍然是一个问题,但是:
令人惊讶的完整 getid3() ( http://getid3.org ) 项目将解决您的所有问题。查看此论坛帖子以获取更多信息。
使用 composer 安装 getId3composer require james-heinrich/getid3
然后使用此代码更新您的 id3 标签
// Initialize getID3 engine
$getID3 = new getID3;
// Initialize getID3 tag-writing module
$tagwriter = new getid3_writetags;
$tagwriter->filename = 'path/to/file.mp3';
$tagwriter->tagformats = array('id3v2.4');
$tagwriter->overwrite_tags = true;
$tagwriter->remove_other_tags = true;
$tagwriter->tag_encoding = 'UTF-8';
$pictureFile = file_get_contents("path/to/image.jpg");
$TagData = array(
'title' => array('My Title'),
'artist' => array('My Artist'),
'album' => array('This Album'),
'comment' => array('My comment'),
'year' => array(2018),
'attached_picture' => array(
array (
'data'=> $pictureFile,
'picturetypeid'=> 3,
'mime'=> 'image/jpeg',
'description' => 'My Picture'
)
)
);
$tagwriter->tag_data = $TagData;
// write tags
if ($tagwriter->WriteTags()){
return true;
}else{
throw new \Exception(implode(' : ', $tagwriter->errors));
}
您可以查看getID3() 项目。我不能保证它可以处理图像,但它确实声称能够为 MP3 编写 ID3 标签,所以我认为这将是你最好的选择。
我不只是分享专辑封面更新的代码,而是将我的整个 MP3 包装类 getID3 发布在这里,以便您可以随意使用
$mp3 = new Whisppa\Music\MP3($mp3_filepath);
//Get data
$mp3->title
$mp3->artist
$mp3->album
$mp3->genre
//set properties
$mp3->year = '2014';
//change album art
$mp3->set_art(file_get_contents($pathtoimage), 'image/jpeg', 'New Caption');//sets front album art
//save new details
$mp3->save();

还没有任何错误处理代码。目前,当我尝试运行任何操作时,我只是依赖异常。随意修改和使用。需要 PHP GETID3
这是使用 getID3 添加图像和 ID3 数据的基本代码。(@frostymarvelous 的包装器包含等效代码,但我认为展示基础知识很有帮助。)
<?php
// Initialize getID3 engine
$getID3 = new getID3;
// Initialize getID3 tag-writing module
$tagwriter = new getid3_writetags;
$tagwriter->filename = 'audiofile.mp3';
$tagwriter->tagformats = array('id3v2.3');
$tagwriter->overwrite_tags = true;
$tagwriter->remove_other_tags = true;
$tagwriter->tag_encoding = $TextEncoding;
$pictureFile=file_get_contents("image.jpg");
$TagData = array(
'title' => 'My Title',
'artist' => 'My Artist',
'attached_picture' => array(
array (
'data'=> $pictureFile,
'picturetypeid'=> 3,
'mime'=> 'image/jpeg',
'description' => 'My Picture'
)
)
);
?>
@carrp $Tagdata 代码将不起作用,除非每个值属性都是一个数组,例如
$TagData = array(
'title' => ['My Title'],
'artist' => ['My Artist'],
'attached_picture' => array(
array (
'data'=> $pictureFile,
'picturetypeid'=> 3,
'mime'=> 'image/jpeg',
'description' => 'My Picture'
)
)
);
使用 PHP 的这个内置函数,
<?php
$tag = id3_get_tag( "path/to/example.mp3" );
print_r($tag);
?>
我认为 PHP 真的不可能。我的意思是,我想一切皆有可能,但它可能不是原生 PHP 解决方案。从PHP Docs,我认为唯一可以更新的项目是:
对不起。也许 Perl、Python 或 Ruby 可能有一些解决方案。
我不确定你是否熟悉 Perl(我个人不喜欢它,但是,它擅长这样的事情......)。这是一个似乎能够在 MP3 中提取和编辑专辑封面的脚本:http ://www.plunder.com/-download-66279.htm
