I have a page output done in PHP and I would like to make it output in a PDF format to prevent modification of it. Is there any "free" open source program like http://www.interakt.ro/products/PDFreports/
Even better, PHP can write PDF's directly. Search the manual and the net for more info.
Anybody with the right tools can write/rewrite PDF's. You are just making it a little more difficult to change your data.
