Answering my own question... I found this user comment at php.net/pdf_open_file. As you can see is dated feb 2002 (kind of old) Is this still true? Does anyone knows gbl@bso2001.com?
Help! =)
Thanks.

Appending to PDF files: plainly, you can't. PDF files have an internal structure that would get corrupted by just appending to the file. You'd need to parse the PDF, create a new PDF and mix your additions with the old PDF. Just creating a new one should be *much* easier.
Reading back the results: do a fopen() on the temporary file and use fgets() to read it. In your example where you just want to output the file, passthru should do the trick.

Hi List!
I'm using the following code to open a pdf form, place a picture and then save it. This is very new for me, and the code is giving me some errors like (Fatal error: PDFlib error: Empty document in c:\Inetpub\wwwroot\pdf_forms\dbtree.php on line 415
). Can somebody help? (line 415 is empty, line 414 is "pdf_close")
TIA.

// write the commands to place the image here.
