title: Generate and Decode QR Codes from PHP
body: <p>Can anyone recommend a PHP library (if one exist) that will generate and decode QR codes? This seems to do the job: <a href="http://code.google.com/p/zxing/" rel="nofollow">http://code.google.com/p/zxing/</a> but it is in Java. If I have to use ZXing, how do I make it work from PHP?</p>
