Barcode and QR code generation and reading library for PHP 8.1+.

Encodes data into 1D and 2D barcode symbologies and renders them as HTML, raster images (via horde/Image), SVG or PDF (via horde/Pdf). Decodes barcodes from module matrices and bar patterns back into structured data. Includes a semantic layer for some popular structured payload formats (payments, contacts, WiFi, GS1, healthcare, etc.) with bidirectional encode/decode support.

Status: Encoding and rendering are fully implemented. Reading/decoding from images is designed (interfaces defined) but not yet implemented. Contributions welcome. :)

Quick Start

use Horde\Barcode\Barcode;

// QR code as HTML table
echo Barcode::qrHtml('https://www.horde.org/');

// Code 128 as HTML
echo Barcode::code128Html('INV-2026-0042');

// EAN-13 as HTML
echo Barcode::eanHtml('5901234123457');

// Data Matrix as HTML
echo Barcode::dataMatrixHtml('Serial:ABC123');

Requirements

• PHP 8.1+ with ext-mbstring
• No other required dependencies (HTML renderer is standalone)

Optional

• horde/image for raster (PNG/JPEG) and SVG output
• horde/pdf for PDF output
• horde/otp for OTP provisioning URI generation
