-
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.
