.doc download problem

[grejon04]

I'm having a problem downloading doc files. The files download, but when opened, contain all sorts of gibberish. The files are fine on the server. PDF files downloaded and run from the same script work fine.

 

The site is run over SSL. Apache, MAC OSX server, connected to MySQL database.

 

Any help would be appreciated. I'm really stumped, here.

Narrowed down code some...

 

	if($go && file_exists($file)){

	header('Content-Description: File Transfer');
	header("Pragma: cache");
	header("Expires: 0");
	header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
	header("Cache-Control: public");

	session_cache_limiter("must-revalidate");


	if ($_GET['type'] == 'doc')
		header('Content-Type: application/msword');

	if ($_GET['type'] == 'pdf')
		header('Content-Type: application/pdf');

	header("Content-Transfer-Encoding: binary");
	header('Content-Length: ' . filesize($file));

	if ($_GET['type'] == 'doc')
		header('Content-Disposition: attachment; filename=' . $title . ".doc");

	elseif ($_GET['type'] == 'pdf')
		header('Content-Disposition: attachment; filename=' . $title . ".pdf");
	//old way of doing it
	//readfile($file);
		readfile_chunked($file,false);

	exit();

Do you actually have a question?

Sorry, this was supposed to be a reply.

 

The problem I'm having is that .doc files that are fine download and are read as lots of gibberish. .PDF files using the same script come off fine.
