Generate QR Code with PHP Using Google API

What is QR Code
QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed.

Thanks David, I`ve updated the code, so it should not generate any warnings now.

I need to create custom qr codes. If I could save the image to a file I could loop through from mysql... How could I write the qr code to file?

The Google API has a problem in that you can`t get a version 1 QR code from 16 characters. It cuts off at 15. The chld argument isn`t followed exactly and there are problems with the margins. Overall I wouldn`t trust this API much. It`s better to do something like "PHP QR Code" that actually works correctly and will give you a 21x21 when its supposed to, instead of a harder to scan 25x25.
