[PHP] Correct headers for I.E. to open PDF?

[Paul Danko]

I have searched the net, and found tons of developers with different
solutions to this problem, none of which I have found to work. 
 
What should the headers be for a client to download a PDF document and
have it open using adobe i.e. pluggin??
 
Here is code I am using, it works on some versions of I.E., but not all:
 
 
$pdfdoc = $__BASE_PDF_BUILD_DIRECTORY.$_GET['FID'];

$filesize = filesize($pdfdoc);
header(Pragma: );
header(Expires: 0); 
header(Cache-Control: must-revalidate, post-check=0,pre-check=0);
header(Content-type: application/pdf);
header(Content-Length: .$filesize);
header(Content-Disposition: inline; filename=FILE.pdf);
header(Content-Transfer-Encoding: binary);
header(Accept-Ranges: bytes);

readfile($pdfdoc);
exit();
 
 
Why isn't it working?
 
Thanks,
 
-Paul

IE can seems to ignore these headers some times (I think it might have
something to do with the .php extension).  I have had success creating
the file and saving it with .pdf as the extension then redirecting to
that file.

If you attempting this over a secure connection (which I assume is why
you're having so much trouble) I.E. can be pretty gay. If it is over a
secure connection, it has to do with I.E. not being able to write to cache
or something. I forgot -- I ran into this a while back. If it's not over a
secure connection, I.E. is still gay. :-)

Try this:

header('Content-Type: application/pdf');
header('Content-Length: '.$filesize);
header('Content-Disposition: inline; filename=FILE.pdf');
header(Cache-Control: private);
header(Pragma: public);

readfile($pdfdoc);
exit();

When all else fails - force a download:

if(isset($HTTP_SERVER_VARS['HTTP_USER_AGENT']) 
strpos($HTTP_SERVER_VARS['HTTP_USER_AGENT'],'MSIE'))
header('Content-Type: application/force-download');
else
header('Content-Type: application/octet-stream');
header('Content-Length: '.$filesize);
header('Content-Disposition: inline; filename=FILE.pdf');
header(Cache-Control: private);
header(Pragma: public);

This has nothing to do with PHP or the server, but with the way the client
computer is configured.
If the user doesn't want to open a .pdf file in the browser but to be
prompted for saving the file, that's the way he will have it.
...fortunately.

This can be difiult to control sometimes.  You could send a header
like so:

  header(Content-Type: application/octet-stream);

Will generally do the trick.  There are times when i've seen IE
behave in very wierd, no matter the content-type, for example,
accessing a url like:
  
  http://domain.com/a/file.php?param=1bar=.jpg

IE may attempt to display the thing in the browser because it saw
the .jpg extension, even though I sent a headers that should
have prompted a download.

IE has gotten better but it still all depends on how the person has
their computer set up to handle content types (IE tries to be too
smart sometimes.)
