This doesn't quite make sense to me. You would normally use PHP to construct a page which displays all the information, with the information itself being returned from the database. So, there is only one page but its data changes when the page is requested.
You could use PHP to create or modify a PDF and then forward this to the browser. The browser will normally either offer to download the pdf (and save it) or open it in an in-browser pdf-viewer.
There are a number of PHP-PDF libraries
that enable you to create or modify pdfs.
