[PHP4] pdflib page numbers?

Hi, first post - I have a system that dynamically generates a series of html documents from a database. I want to be able to dynamically generate a pdf document of all these documents into a book so it can be printed out. The problem is that these documents have a lot of crosslinking. Like page 58 might refer the reader back to page 36 for related information on one topic, or page 79 on another topic. This is for the convience of those who read the hard-copies. This page-flipping is an integral part of the set of documents so it isn't an option to re-engineer that approach. I'd imagine that each html document would correspond to 2-3 pages of html text. You can probably imagine the problems this brings up - pdflib doesn't seem to have a way to return what page number you are on. Do I actually have to control pdflib through php to the extent of querying the length of my document contents and breaking in here and there to manually enter PDF_end_page and PDF_begin_page, or will it automatically start a new page when a bottom margin is reached? Also, is there an easier way to determine page numbers of sections other than cycling through all the documents, counting how many times I have iterated through "PDF_begin_page" to find page numbers of different documents, storing that information in php objects, and then throwing out the pdf document and generating the whole document AGAIN to insert the page numbers in its crosslink references? Hope I asked that clearly. Thanks, Curt
