PHP QRcode Generator

gQRcode is a QR code rendering class that uses the Google Charts API.

How to use this class

Include the class in your script and use setter methods to define QR code attributes. The class uses dynamic setters via the magic __call() function so you can set any custom attributes you want.

Example - generating a QR code image with contact information:

// Include the library
require('gQRcode.php');
// Instance of the QR code class
$gQRcode = new gQRcode();
// Add the contact information using setters
$gQRcode->name("Name Example")
        ->company("NameCompany")
        ->phone("123456")
        ->email("test@noreplay.com")
        ->address("bla blabla")
        ->AllThatYouWant("Hello World");
// and embed the QR code in the page as a simple HTML img
echo $gQRcode->embed();

Class methods
