To echo and expand on what others have said, you can't really send the file using AJAX. One of the reasons for this is (and someone correct me if I'm wrong on this, please) that the page you're currently on already has sent its content headers; you can't send them again to the same window, even with an AJAX request (which is what your PHP file is attempting to do).
