In Firefox, Google browser download normal, ie and thunder download file is not complete

Reply to discussion (solution)

Ob_clean ();
Flush ();
ReadFile ($file);

Ob_clean ();
Flush ();
ReadFile ($file);

That's what I'm saying!

No MIME header

Header ("Content-transfer-encoding:binary");
Header ("Content-length:". $len);
These two, try to erase it.

No MIME header

MIME type? Add that, IIS?

Header ("Content-transfer-encoding:binary");
Header ("Content-length:". $len);

$len = FileSize ($file);
Header ("Content-length:". $len);
The above 2 sentences can be downloaded after deletion, but no statistics file size, thunder and IE did not show the length of the download.

Nginx + PHP environment Without you said that the problem, ie and thunder can be normal download but my file is flv, so it can only indicate that the MIME header error
My code is as follows:

function Dl_file ($file) {
$len = FileSize ($file);
$filename = basename ($file);
$file _extension = Strtolower (substr (STRRCHR ($filename, "."), 1);
Switch ($file _extension) {
Case "mp4": $ctype = "Video/mp4"; Break
Default: $ctype = "Application/force-download";
}
Header ("Pragma:public");
Header ("expires:0");
Header ("Cache-control:must-revalidate, Post-check=0, pre-check=0");
Header ("Cache-control:public");
Header ("Content-description:file Transfer");
Header ("Content-type: $ctype");
$header = "content-disposition:attachment; Filename= ". $filename.";
Header ($header);
Header ("Content-transfer-encoding:binary");
Header ("Content-length:". $len);
Ob_clean ();
Flush ();
ReadFile ($file);
Exit
}
Dl_file (' http://res.805.com/videos/Huo Shan * kanbayashi hou yuan (Yi Qian billion group) [640x480].flv '); Just changed one file name, and nothing else has changed.

IE, Thunder download have display file size?

It's not tested. There's a "content-length head."

You can take a look at the Ucenter document.
