qr

cline/qr is a standalone QR code generation and decoding package. The repository keeps the Cline project skeleton for tooling and maintenance while the implementation and test coverage live directly in this package.

Requirements

Requires PHP 8.4+

Installation

composer require cline/qr

Usage

use Cline\Qr\Builder\Builder;
use Cline\Qr\Writer\PngWriter;

$result = new Builder(
    data: 'Hello world',
)
    ->withWriter(new PngWriter())
    ->build();

file_put_contents('qr.png', $result->getString());

Public immutable value objects also expose additive with* methods when you want to derive a modified copy without going back through the builder:

use Cline\Qr\Color\Color;
use Cline\Qr\QrCode;

$qrCode = (new QrCode('Hello world'))
    ->withSize(512)
    ->withMargin(4)
    ->withForegroundColor(new Color(12, 34, 56));
