header["Cache-Control: public"];
header['Content-Disposition: inline; filename="' . $file . '"'];

Display Doc file on Browser
Their is no way you can display Doc file on browser, you can only user google reader but google reader don't open password protected files, for google reader you need to give public access file to view on browser
In this tutorial, we are going to see how to open a PDF file in browser with PHP. PHP uses standard code to display the pdf file in the web browser. The process of viewing the PDF file involves locating the PDF file on the server. It uses various types of headers to define the composition of the content in the form of Type, Layout, Transfer-Encode, etc. PHP transmits the PDF files to be able to read them on the browser. The browser displays it or downloads it from the
localhost server, then displays the pdf.
