The two code snippets presented in this page can be used to output audio MP3 files, or to force the Download, with PHP.
- Click on the code to select it.

Output MP3 with PHP

$mp3 ='path_to/mp3_file.mp3';
if(file_exists($mp3)) {
  header('Content-Type: audio/mpeg');
  header('Content-Disposition: inline; filename="mp3_file.mp3"');
  header('Content-length: '. filesize($mp3));
  header('Cache-Control: no-cache');
  header('Content-Transfer-Encoding: chunked'); 
  readfile($mp3);
  exit;
}

Force Download MP3 file with PHP

$mp3 ='path_to/mp3_file.mp3';
if(file_exists($mp3)) {
  header('Content-Type: audio/mpeg');
  header('Content-Disposition: attachment; filename="mp3_file.mp3"');
  header('Content-length: '. filesize($mp3));
  header('Cache-Control: no-cache');
  header('Content-Transfer-Encoding: chunked'); 
  readfile($mp3);
  exit;
}
- Notice, the only difference is to this header():
header('Content-Disposition: attachment; filename="mp3_file.mp3"');
- "inline" to play the MP3 within the browser (if capabilities exist), and "attachment" to force download.
