JPGraph has some capabilities.  This little script shows how to call the Google interface.  You can install it on your server and test it, or run it on my server here.

Eh?  The practical answer might be to use the Google interface (that is what I do and that is what I posted) however hernst42 posted a link to a self-contained native-PHP class for producing QR Codes in image or text (console or document) that uses no other files or modules.  This is exactly what you asked for.

I will post an objection so you can engage in some dialog or accept the correct answers.  Good luck with your project, ~Ray
