[PHP] Web Client - How to open applications by their own.

[Okar]

I m using the following attachment handling code in my web client
?
// supposing that:
// $encoding = 'BASE64';
// $pid = attachment's pid;
// $file = attachment's file name;
// $size = $object-bytes;
// $type = $object-type;
// $subtype = $object-subtype;
//...
$attch = imap_base64(imap_fetchbody($mbox, $id, $pid));
//...
$types = array(text, multipart, message, application, audio,
image, video, other);
$cont_type = $types[$type]./.$subtype;
header(Content-transfer-encoding: binary\n);
header(Content-type: $cont_type\n);
if (strstr($_SERVER[HTTP_USER_AGENT], MSIE))
  header(Content-Disposition: filename=$file\n); // For IE
else
  header(Content-Disposition: attachment; filename=$file\n); // For non-IE
browsers
header(Content-length: $size\n );
print $attch;
?
Regardless the nature of the attachment, things are happening expectedly (as
far as I tested) as long as the SAVE button of the browser's save-file
dialog is clicked.
The OPEN button works fine as well, for browser compatible files such as
.jpeg, .gif, .txt, etc...
But when it's matter of opening per ex. a MSPoverPoint *.pps slide-show file
as attachment through the browser's save-file dialog (well, the button is
there and any user may click it) the smooth running web client turns into a
PoverPoint application opened through the browser's window with an empty
project in design view.
Wrapping above code with
?
 $tmpfname = tempnam (0, 0);
 $fp = fopen($tmpfname, w);
 fwrite($fp, $attch);
 fclose($fp);
...
 unlink($tmpfname);
?
didn't help too much.
Would there be a way to force the browser to download the attachment in a
temporary location and launch the application (MSPowerPoint in this case) by
its own?

Hi Okar,


the client decides what to do with incoming data in regard of 
the MIME type.

Usually, there is a list of MIME type and corresponding action 
in the clients browser, and you can't change it from the server.
