Unfortunately I don't have the links straight off-hand, but when I get a chance I'll see if I can get them again. The biggest thing I found was a server-side extention called PDF-Lib, which made it very, very easy to generate PDF files through
PHP coding, however I go through a webhost so I wasn't able to use PDF-Lib. I ended up going another route with what I needed for this, so soon after I found this information, I didn't need it anymore. I'll see if I can scrounge something up later tonight or tomorrow, but for now you can probably do a quick Google search on PDF-Lib and find lots of info.
