Answer 1

header("Content-Type: application/octet-stream");
header('Content-Disposition: attachment; filename="' . OCIResult($stid,'PDFFILE') . '"');    
header("Content-Length: " . filesize(OCIResult($stid,'PDFFILE')->load()));
header('Content-Disposition: attachment; header("Content-Transfer-Encoding: binary\n");

You're sending the Content-Disposition header twice. You probably don't even need the second one, the client should know all it needs to know about the stream from the Content-Type header. Omit the second Content-Disposition so you're not over-writing the header that has the filename.
