PHP获取远程.mp3文件的元数据(来自URL)


PHP Get metadata of remote .mp3 file (from URL)

我正试图从远程.mp3文件
(如)获取song name/artist name/song length/bitrate等http://shiro-desu.com/scr/11.mp3

我尝试过getID3脚本,但据我所知,它不适用于远程文件,因为我收到了以下错误:"不支持远程文件-请先在本地复制文件"

此外,此代码:

<?php
$tag = id3_get_tag( "http://shiro-desu.com/scr/11.mp3" );
print_r($tag);
?>

也不起作用
"致命错误:在第2行调用/home4/shiro/public_html/scr/index.php中未定义的函数id3_get_tag()"

由于您没有提到您的错误,我正在考虑常见的错误案例undefined function

The error you get (undefined function) means the ID3 extension is not enabled in your PHP configuration:

如果你没有Id3扩展文件。只需在这里查看安装信息。

首先,我没有创建这个,我只是用一个完整的例子让它更容易理解。

你可以在这里阅读更多,但这只是因为archive.org。https://web.archive.org/web/20160106095540/http://designaeon.com/2012/07/read-mp3标签而不下载/

首先,从这里下载此库:http://getid3.sourceforge.net/

当你打开zip文件夹时,你会看到"getid3"。将该文件夹保存到您的工作文件夹中。

接下来,在运行以下脚本的工作文件夹中创建一个名为"temp"的文件夹。

基本上,它所做的是下载文件的前64k,然后从文件中读取元数据。

我喜欢一个简单的例子。我希望这能有所帮助。

<?php
require_once("getid3/getid3.php");
$url_media = "http://example.com/myfile.mp3"
$a=getfileinfo($url_media);
echo"<pre>";
echo $a['tags']['id3v2']['album'][0] . "'n";  
echo $a['tags']['id3v2']['artist'][0] . "'n";  
echo $a['tags']['id3v2']['title'][0] . "'n";  
echo $a['tags']['id3v2']['year'][0] . "'n"; 
echo $a['tags']['id3v2']['year'][0] . "'n";  
echo "'n-----------------'n";
//print_r($a['tags']['id3v2']['album']);
echo "-----------------'n";
//print_r($a);
echo"</pre>";
