2.php类库PHP QR Code

PHP QR Code is open source (LGPL) library for generating QR Code, 

2-dimensional barcode. Based on libqrencode C library, 

provides API for creating QR Code barcode images (PNG, JPEG thanks to GD2).

Implemented purely in PHP, with no external dependencies (except GD2 if needed).
