Duna QR Code Library ¶
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);
