Hey,
Dont really understand the Array > PDF thing, but if you want to write PDF files you best bet would be to get a PDF class working. I have a project in wich i use advanced pdf writing, i use the domPDF class wich writes pdf files from html marking. It has alot of limitations and you need to learn to write html like its 1999 but its a very good and easy to use class.
There is even a CI library that helps glue the class to CI.
Do a search and good luck.
Best regards.
