PDF Watermark and Ammendments using Codeigniter

[eluser]Unknown[/eluser]
Hi,

I'd like to know if anyone knows how I would go about amending a PDF to add additional details (based on variable information) that would change very every person downloading it.

The people downloading said PDF must have a subscription to do so, and at the bottom of the PDF document, it needs to say "Licensed to ...". Obviously that will change depending on who downloads it, therefore it needs to be dynamic and pull in details (just the name) from the database.

Are their any libraries that would help me achieve this?

Any help is appreciated

Oliver
