如何强制PHP文档返回的八位字节流上的标题？

Question

I already tried to find an answer to this question on this site but I'm a bit unexperienced and my knowledge is limited yet.

My situation is as follows: I have an external PHP file (say http://example.org/get.php) (which I cannot edit) that returns an MP3 file as an octet-stream. The problem is that I need it to be an audio/mp3 in order to use it with an HTML5 audio player. How can I achieve this?

I think I cannot just do something like

$mp3_url = 'http://example.org/get.php?file=123'; header('Content-Type: audio/mp3');

, can I?

One way is to setup a proxy on your server, e.g. /your/script.php might look like

header('Content-Type: audio/mp3', true, 200);
echo file_get_contents($_GET['url']);

(security checks skipped)

Then you can use it as <a href="/your/script.php?url=http%3A%2F%2Fexample.org%2Fget.php%3Ffile%3D123">link</a>

Another way is to setup a proxy using Web server such as Nginx or Apache.
