Does anyone know of a PHP class which generates QR codes on your server instead of relying on the now deprecated Google Charts API which will not always be in existence.
I'm also thinking that bulk QR code generation will be faster if it's done on the server.
I would also consider a client based JS or Jquery solution to the problem.
Theres this one...its for javascript though...
http://d-project.googlecode.com/svn/trunk/misc/qrcode/js/
or this....PHP lib
http://phpqrcode.sourceforge.net/
I've just started using visuallead. The syntax is pretty simple. This syntax:
http://open.visualead.com/?data=paper.exchange&size=110&type=png
Yields this:
