You have to handle the http request header sent by the client.
There will be a line like this:
Range: bytes=339843-2392437
That means that the client requests the bytes between 339843 and 2392437
So after your fopen(), you should send those bytes to the client. I guess you will need to use fseek and then fread.
Your response header should start with
HTTP/1.1 206 Partial Content
and should have these 3 lines:
Accept-Ranges: bytes
Content-Length: 2052595
Content-Range: bytes 339843-2392437/2392438
You can find more info at these pages:
