bacon/bacon-qr-code 2.0.8

The "bacon/bacon-qr-code" is a compositor package that casts as a QR code generator for PHP. It's an adopter of the QR code portion of the ZXing library. It was primarily designed to encode the QR code information. Its setting includes the Reed Solomon codec implementation which, despite being a bit slow in PHP, was chosen to replace the ZXing library's original implementation due to the latter's performance index.

Use of the package "bacon/bacon-qr-code" in your PHP code is quite straightforward. Once you have it installed, you can generate a QR code image file for any text like this:

use BaconQrCode\Renderer\ImageRenderer;
use BaconQrCode\Renderer\Image\ImagickImageBackEnd;
use BaconQrCode\Renderer\RendererStyle\RendererStyle;
use BaconQrCode\Writer;

$renderer = new ImageRenderer(
    new RendererStyle(400),
    new ImagickImageBackEnd()
);
$writer = new Writer($renderer);
$writer->writeFile('Hello World!', 'qrcode.png');

In this example, the text 'Hello World!' is being encoded as a QR code, and the QR code image is getting saved to a file called 'qrcode.png'.

There are several image rendering back ends available, including ImagickImageBackEnd for rendering raster images using the Imagick library, the SvgImageBackEnd for rendering SVG files using XMLWriter, and the EpsImageBackEnd for rendering EPS files.

The documentation for the "bacon/bacon-qr-code" package is embedded within the README file at the GitHub repository: https://github.com/Bacon/BaconQrCode. The README serves as a comprehensive guide for installing, learning, and effectively implementing the QR code generation features provided by this PHP library.
