PHP QR Code

PHP QR Code is an open source library (LGPL) for generating QR Code images.

Based on libqrencode C library, provides an API to create QR Code barcode images (PNG, JPEG thanks to GD2).

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

Example

include('qrlib.php');

// saída direta para o navegador da imagem com o QR Code na forma de PNG
QRcode::png('Dados aqui que pode ser o caminho completo para o ficheiro');

For the output to be applied to the page, you can use something like:

// tag <img/> com caminho para o PHP que gera o QR Code
echo '<img src="qrcode_do_meu_ficheiro.php" />';

You can consult the countless examples directly on the library website.
