PHP dynamically create a custom PDF from mySQL database

I have a requirement to create a custom report based on data stored in a mySQL database. I would like to create a function that will render a PDF on the fly and when finished pop up a save as box or something similar for the user to save, or pop up a new window displaying the PDF giving the option for the user to save.

I have done some research and found a few options but was wondering if someone has done something like this before and has a reco开发者_如何学Gommendation. Alot of what I have found is really old or costs money. I would like to find something free if possible.

I want to be able to control exactly where things are placed on the document, insert images, font sizes, etc...

Thanks for any recommendations

I've used FPDF, and been pretty happy with it.
