Metzli is a PHP library to generate Aztec 2D barcodes.

Just install Composer and run composer require z38/metzli in your project directory.

Using Metzli in your existing project is very easy:

require 'vendor/autoload.php';

use Metzli\Encoder\Encoder;
use Metzli\Renderer\PngRenderer;

// ... some awesome code here ...

$code = Encoder::encode('Hello World!');
$renderer = new PngRenderer();

header('Content-Type: image/png');
echo $renderer->render($code);

If you want to get your hands dirty, great! Here's a couple of steps/guidelines:

• Fork this repository
• Add your changes & tests for those changes (in tests/).
• Remember to stick to the existing code style as best as possible. When in doubt, follow PSR-2.
• Send me a pull request!

If you don't want to go through all this, but still found something wrong or missing, please let me know, and/or open a new issue report so that I or others may take care of it.

Metzli is heavily based on ZXing and is basically a port of its Aztec encoding part.
