Atelier Barcode

QR codes, matrix codes, and barcodes as SVG, in pure PHP.

Build QR Code, Data Matrix, Code 39, Code 93, Code 128, Codabar, EAN/UPC, ITF, GS1, and ISBN symbols and render them straight to SVG with a fluent, type-safe API. No required extensions, no image library, no runtime dependencies. Each builder returns a string of SVG markup that works in an <img>, a background-image, inline <svg>, a PDF, or an email.

Installation

composer require atelier/barcode

Requires PHP 8.3+. Pure PHP, no extensions.

---

Quick start

use Atelier\Barcode\QrCode;
use Atelier\Barcode\Ecc;

$svg = QrCode::create('https://ateliersvg.com')
    ->ecc(Ecc::Medium)
    ->size(240)
    ->margin(4)
    ->render();

file_put_contents('qr.svg', $svg);

A linear barcode is the same shape of call:

use Atelier\Barcode\Code128;

echo Code128::create('ATELIER-2026')->render();

Symbologies

Preview, options, limits, and a usage example for each; full detail lives on its own page.

Symbology	Preview	Kind	Input
Code 128		1D linear	7-bit ASCII
Code 39		1D linear	A-Z 0-9 space - . $ / + %
Code 93		1D linear	A-Z 0-9 space - . $ / + %
Codabar		1D linear	digits, - $ : / . +, guards A-D
Data Matrix		2D matrix	extended ASCII, up to 44 chars
EAN-8		1D linear	7-8 digits
EAN-13		1D linear	12-13 digits
GS1-128		1D linear	GS1 AI pairs
GS1 DataMatrix		2D matrix	GS1 AI pairs, single-region
Interleaved 2 of 5		1D linear	even-length digits
ISBN		1D linear	ISBN-10 or ISBN-13
ITF-14		1D linear	13-14 digits
QR Code		2D matrix	numeric, alphanumeric, or byte data
UPC-A		1D linear	11-12 digits
UPC-E		1D linear	6-8 digits, number system 0 or 1

All builders are mutable fluent objects created with ::create() and finished with render(), which returns SVG. QrCode/DataMatrix also expose matrix(); linear symbologies expose modules(). Both return the raw geometry instead of SVG.

Every builder shares margin(), foreground(), background(), and a size call (size() for 2D, scale()/height() for linear). See each symbology's page for its full option table, defaults, bounds, and the exceptions it throws.

Error handling

All package exceptions implement Atelier\Barcode\Exception\CodeExceptionInterface.

use Atelier\Barcode\Exception\CodeExceptionInterface;
use Atelier\Barcode\QrCode;

try {
    echo QrCode::create($payload)->render();
} catch (CodeExceptionInterface $e) {
    // Invalid input, unsupported characters, missing optional extension,
    // invalid renderer color, or output dimensions beyond safety limits.
}

Concrete exceptions live in Atelier\Barcode\Exception: InvalidCodeException, InvalidColorException, and MissingExtensionException.
