A versatile QR code generation library that supports HTML, PNG, and SVG output formats.

Overview ¶

The Duna QR Code Library is a QR code generation tool originally based on the QrCode library bundled with Duna until v8.0, developed by Laurent Minguet. It is distributed under the LGPL license, providing a flexible and open-source solution for QR code generation.

Installation ¶

To install the library, use Composer:

$ composer require duna/qrcode

Usage ¶

Here's a quick guide to using the Duna QR Code Library:

Generating QR Codes ¶

First, include the necessary classes and create a QR code instance:

<?php

use Duna\Helpers\QrCode\QrCode;
use Duna\Helpers\QrCode\Output;

$qrCode = new QrCode('Lorem ipsum dolor sit amet');

Output Formats ¶

PNG Output ¶

To generate a PNG image of the QR code, specifying dimensions and colors, use:

// Create PNG output
$output = new Output\Png();

// Generate PNG data with a specified width, background color (white), and foreground color (black)
$data = $output->output($qrCode, 100, [255, 255, 255], [0, 0, 0]);

// Save the PNG data to a file
file_put_contents('file.png', $data);

SVG Output ¶

For SVG output, which is useful for scalable vector graphics:

// Create SVG output
$output = new Output\Svg();

// Generate SVG data with a specified width, background color (white), and foreground color (black)
echo $output->output($qrCode, 100, 'white', 'black');

HTML Output ¶

To display the QR code as an HTML table:

// Create HTML output
$output = new Output\Html();

// Generate HTML table representation of the QR code
echo $output->output($qrCode);
