display .msg file in browser using php - php

Question

I have attached outlook msg file in php application. I am storing that file in sql server database.
Now i want to open and display it from browser.
I tried this code :
if($ext=="msg")
{
header('ContentType : application/octet-stream');
header('Content-Disposition: attachment; filename='. basename($filename));
echo base64_decode($file);
}
$filename and $file are coming from database.
Its opening msg file in outlook from IE and chrome but its not openning from firefox.
Is there any way to make it working in all the browser ?
Or Am i wrong somewhere or is there any setting in browser ?

Answer 1

I had an almost similar situation and was able to solve it.
Include the headers below and it should work just fine.
Regards
header("Pragma: public");
header("Expires: 0");
header('Content-Encoding: UTF-8');
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-type: application/vnd.ms-outlook;charset=UTF-8");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=test.msg");
header("Content-Transfer-Encoding: binary ");
