How to stream a media file using PHP?

Question

I am trying to build an application in which i have to stream the media files (audio and video) to the browser. I am reading the file through php and send the data to browser. I am using the following code.

header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Content-Type: {$file->getMimetype()}");
header("Content-Disposition: inline; filename=".$filename.";");
header("Content-Length: ".strlen($file_content));

echo $file_content;

Every thing is working fine, except when i try to forward the video or audio, (I mean suppose current play location is 0:15 and it directly go to 1:25), media stops and when i press the play button again, it starts from the beginning.

I think the problem is with the buffering, but can't figure it out. Am i doing something wrong in header or something else is required.

Thanks.

Answer 1

I think you need to implement the Range header, so that the client can skip to a specific position in the file. You can probably find out what goes wrong by sniffing the request the player sends.

Answer 2

What you want is called "Content-Range requests"
