我正在寻找使用PHP设置mp3专辑封面的最佳或任何方法。
有建议吗?
专辑封面艺术是一个数据框,由ID3v2规范中的“附加图片”标识,而getID3()现在是使用纯PHP编写所有可能的ID3v2数据框的唯一方法。
看看这个源代码: http://getid3.sourceforge.net/source/write.id3v2.phps
在源代码中搜索此文本:
// 4.14 APIC Attached picture
有一段代码负责写入专辑封面。
另一种方式,似乎不如纯PHP慢,是使用一些外部应用程序,由PHP脚本启动。如果您的服务旨在承受高负载,则二进制编译工具将是更好的解决方案。
更好(更快)的方法是通过外部应用程序和PHP exec()函数执行命令。我建议使用eyeD3。
使用Composer安装getId3 composer require james-heinrich/getid3
然后使用以下代码更新您的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));
}
我不仅会分享更新专辑封面的代码,还会在这里发布我的整个getID3 MP3包装类,以便您根据需要使用
$mp3 = new Whisppa\Music\MP3($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();

目前还没有任何错误处理代码。当前,我只是在尝试运行任何操作时依赖于异常。 请随意修改并使用。需要 PHP GETID3。
\GetId3\GetId3Core
是什么? - Mahmoud.Eskandari这里是使用getID3添加图像和ID3数据的基本代码。(@frostymarvelous的包装器包含等效的代码,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'=> $pictureFile,
'picturetypeid'=> 3,
'mime'=> 'image/jpeg',
'description' => 'My Picture'
)
)
);
?>
@carrp,除非每个value属性都是一个数组,否则$Tagdata代码将无法工作,例如。
$TagData = array(
'title' => ['My Title'],
'artist' => ['My Artist'],
'attached_picture' => array(
array (
'data'=> $pictureFile,
'picturetypeid'=> 3,
'mime'=> 'image/jpeg',
'description' => 'My Picture'
)
)
);
<?php
$tag = id3_get_tag( "path/to/example.mp3" );
print_r($tag);
?>
我认为用PHP实现这个功能可能不太可能。我的意思是,我想任何事情都有可能,但它可能不是一个本地的PHP解决方案。从PHP文档中,我认为唯一可以更新的项目是:
抱歉,伙计。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,但是它在这方面很擅长...)。这里有一个脚本,似乎能够拉取和编辑MP3中的专辑封面:http://www.plunder.com/-download-66279.htm
