title: How to extract data from an already filled up pdf form using any program language?
body: <p>I have a pdf form, I've filled the fields in that form and saved that pdf file as a new pdf file. Now when I open the new pdf file, it automatically loads the data which was filled in earlier. Can I extract that data using any of the language from C/Java/PHP/Javascript, so that I can use that and save that into database?</p>
