The safest way to have a PDF display instead of download seems to be embedding it using an object or iframe element. There are also 3rd party solutions like Google's PDF viewer.

See Best Way to Embed PDF in HTML for an overview.

There's also DoPDF, a Java based In-browser PDF viewer. I can't speak to its quality but it looks interesting.

You could modify a PDF renderer such as xpdf or evince to render into a graphics image on your server  and then deliver the image to the user  This is how Google s quick view of PDF files works  they render it locally  then deliver images to the user  No downloaded PDF file  and the source is pretty well obscured

You can also use fpdf class available at  http   www fpdf org  It gives options for both outputting to a file and displaying on browser

I assume you want the PDF to display in the browser  rather than forcing a download  If that is the case  try setting the Content-Disposition header with a value of inline   Also remember that this will also be affected by browser settings - some browsers may be configured to always download PDF files or open them in a different application  e g  Adobe Reader
