Features
--------

[](#features)

- Dead simple API - one line to generate QR
- Zero runtime dependencies
- PHP 7.4 / 8.0 / 8.1 / 8.2 / 8.3 / 8.4 / 8.5 / 9.0
- QR Code versions 1–40, all error correction levels
- Multiple output formats: SVG, PNG, HTML, ASCII, raw matrix
- ~100% test coverage (186 tests, 2209 assertions)
- PHPStan level max, zero errors
- 17x faster with fixed mask pattern
- PSR-4 autoloading

Requirements
------------

[](#requirements)

- PHP >= 7.4
- ext-gd (optional, only for PNG rendering)

Installation
------------

[](#installation)

```
composer require globus-studio/phpqrcode
```

Usage
-----

[](#usage)

```
use GlobusStudio\QRCode\QRCode;

// SVG string
$svg = QRCode::svg('https://example.com');

// PNG as data URI (requires ext-gd)
$png = QRCode::png('https://example.com');

// HTML table
$html = QRCode::html('https://example.com');

// ASCII art
echo QRCode::string('https://example.com');

// Raw boolean matrix
$matrix = QRCode::matrix('https://example.com');
```

Options
-------

[](#options)

```
use GlobusStudio\QRCode\QRCode;
use GlobusStudio\QRCode\ErrorCorrection\ErrorCorrectionLevel;

$svg = QRCode::svg('data', [
    'level' => ErrorCorrectionLevel::H,
    'size' => 4,
    'margin' => 2,
    'mask' => 3,            // fixed mask 0-7 (skips auto-selection, 17x faster)
    'foreground' => '#000000',
    'background' => '#ffffff',
]);
```

Performance
-----------

[](#performance)

By default the encoder tests all 8 mask patterns to find the optimal one. For batch generation or when speed matters, pass a fixed `mask` (0–7):

```
// ~180ms per QR (auto mask selection)
$svg = QRCode::svg($data);

// ~11ms per QR (fixed mask, 17x faster)
$svg = QRCode::svg($data, ['mask' => 0]);
```

Object API
----------

[](#object-api)

```
use GlobusStudio\QRCode\QRCode;
use GlobusStudio\QRCode\ErrorCorrection\ErrorCorrectionLevel;
use GlobusStudio\QRCode\Renderer\SvgRenderer;

$qr = new QRCode('https://example.com', ErrorCorrectionLevel::H);
$svg = $qr->render(new SvgRenderer(['size' => 6]));
$matrix = $qr->getMatrix();
```
