README

A from-scratch, framework-agnostic QR Code generator for PHP 8.2+ with zero required runtime dependencies.

Features

• Modern PHP support
• Lightweight and fast
• Typed API
• Framework agnostic
• Standards-oriented
• Extensible architecture
• Zero runtime dependencies
• Three renderers (SVG, PNG, Console)
• ISO/IEC 18004 compliant
• Payload helpers (URL, vCard, Event, etc.)

Installation

composer require abduns/qrcode

Quick Start

use Dunn\QrCode\QrCode;
use Dunn\QrCode\EccLevel;
use Dunn\QrCode\Renderer\Svg\SvgRenderer;

$qr = QrCode::create('https://example.com')
    ->errorCorrection(EccLevel::Quartile)
    ->build();

$svg = (new SvgRenderer(size: 300, margin: 4))->render($qr);
file_put_contents('qr.svg', $svg);

Why This Package?

• Existing solutions are outdated
• Missing modern PHP features
• Poor developer experience
• No standards compliance
• Too framework-coupled

This package focuses on simplicity, interoperability, and modern developer ergonomics.

Usage

Basic Usage

use Dunn\QrCode\QrCode;

// Payload helpers
QrCode::url('https://example.com')->build();
QrCode::text('hello')->build();
QrCode::phone('[phone]')->build();
QrCode::sms('[phone]', body: 'hi')->build();
QrCode::email('[e-mail]', subject: 'hello', body: 'hi')->build();
QrCode::geo(37.7749, -122.4194, label: 'SF')->build();

Advanced Usage

use Dunn\QrCode\Renderer\Svg\SvgRenderer;
use Dunn\QrCode\Style\Color;
use Dunn\QrCode\Style\Logo;
use Dunn\QrCode\Style\ModuleShape\DotModule;
use Dunn\QrCode\Style\EyeStyle\CircleEyeOuter;
use Dunn\QrCode\Style\EyeStyle\SquareEyeInner;

$renderer = new SvgRenderer(
    size: 360,
    margin: 4,
    background: Color::hex('#fafafa'),

    // Data dots: round, dark navy.
    moduleShape: new DotModule(),
    dotColor: Color::hex('#264653'),

    // Marker outer ring: round, teal.
    eyeOuter: new CircleEyeOuter(),
    markerOuterColor: Color::hex('#2a9d8f'),

    // Marker inner pupil: square, terracotta.
    eyeInner: new SquareEyeInner(),
    markerInnerColor: Color::hex('#e76f51'),

    // Optional center logo
    logo: Logo::fromFile(__DIR__ . '/logo.png', sizeRatio: 0.18),
);

$svg = $renderer->render($qr);

Configuration

All renderers are highly configurable directly via their constructors.

use Dunn\QrCode\Renderer\Png\GdPngRenderer;
use Dunn\QrCode\Renderer\Console\ConsoleRenderer;

$png = (new GdPngRenderer(size: 300))->render($qr);
echo (new ConsoleRenderer(margin: 2))->render($qr);
