Help !! Extract information to MS-Word

[lovely]

Hi all,

 

Let say i have saved test.doc file in my desktop, i need to know how to retrieve information to this document.

 

When i use this

 

$fileName = 'test.doc';

header("Content-type: application/vnd.ms-doc");

header("Content-Disposition: attachment; filename=$fileName");

 

The above script will open as a seperate document, but i want to d/w in the existing file

 

Thank You
