PHP QR Code

PHP QR Code 是 PHP 用来处理二维条形码的开发包。基于 C 语言的 libqrencode 库开发，提供生成二维条形码功能，包括 PNG、JPG 格式。使用纯 PHP 实现，无需依赖第三方包，除了 GD2 除外。

示例代码：

QRcode::png('code data text', 'filename.png'); // creates file
QRcode::png('some othertext 1234'); // creates code image and outputs it directly into browser

主要特性：

• Supports QR Code versions (size) 1-40
• Numeric, Alphanumeric, 8-bit and Kanji encoding. (Kanji encoding was not fully tested, if you are japan-encoding enabled you cen contribute by verifing it :) )
• Implemented purely in PHP, no external dependencies except GD2
• Exports to PNG, JPEG images, also exports as bit-table
• TCPDF 2-D barcode API integration
• Easy to configure
• Data cache for calculation speed-up
• Provided merge tool helps deploy library as a one big dependency-less file, simple to "include and do not wory"
• Debug data dump, error logging, time benchmarking
• 100% Open Source, LGPL Licensed
