We generate a QR code for PHP

QR-code has long been common everywhere, in all spheres of human life. It seems such a popular thing, but there is no normal library (Open Source) for PHP. Comrade deltalab , he strained this problem very much and he decided to rewrite Kentaro Fukuchi’s C library, ibqrencode , into the more familiar PHP language.

PHP QR Code with an open source (LGPL) library for creating a QR code and 2-dimensional barcodes. It is based on the C library's ibqrencode code. Provides API for creating bar codes in PNG, JPEG format using GD2. Implemented in pure PHP, without any external dependencies, except of course GD2.
