Can I serve MP3 files with PHP?

问题:

In the same way that it's possible to serve up images with php, for use in CAPTACHAS and such, is it possible to do the same with audio files?

I've tried this

<?php

$track = "sometrack.mp3";

if(file_exists($track)) {
    header('Content-type: audio/mpeg');
    header('Content-length: ' . filesize($track));
    header('Content-Disposition: filename="sometrack.mp3"');
    header('X-Pad: avoid browser bug');
    header('Cache-Control: no-cache');
    print file_get_contents($track);
} else {
    echo "no file";
}

I'm using Safari, which can play MP3 files. It's kicking Safari into the right mode, I get the Quicktime controls for a few seconds, and then "No Video".

I'm trying to protect files from unauthorized download in case you're wondering why I'd want to do this.

回答1:

Your Content-Disposition should be:

header('Content-Disposition: attachment; filename="sometrack.mp3"');

Not sure if that's the problem though. I would also recommend using readfile to output the file:

readfile($rSong);

Also, it can't hurt to use an exhaustive Content-Type header, and set the Content-Transfer-Encoding:

header("Content-Transfer-Encoding: binary"); 
header("Content-Type: audio/mpeg, audio/x-mpeg, audio/x-mpeg-3, audio/mpeg3");
