QR Code

This library based on QRcode Perl CGI & PHP scripts by Y. Swetake helps you generate images containing a QR code.

Installation

Use Composer to install the library.

$ composer require endroid/qrcode

Then, require the vendor/autoload.php file to enable the autoloading mechanism provided by Composer. Otherwise, your application won't be able to find the classes of this library.

Of course you can also download the library and build your own autoloader.

Usage

use Endroid\QrCode\QrCode;

$qrCode = new QrCode();
$qrCode
    ->setText('Life is too short to be generating QR codes')
    ->setSize(300)
    ->setPadding(10)
    ->setErrorCorrection('high')
    ->setForegroundColor(array('r' => 0, 'g' => 0, 'b' => 0, 'a' => 0))
    ->setBackgroundColor(array('r' => 255, 'g' => 255, 'b' => 255, 'a' => 0))
    ->setLabel('Scan the code')
    ->setLabelFontSize(16)
    ->setImageType(QrCode::IMAGE_TYPE_PNG)
;

// now we can directly output the qrcode
header('Content-Type: '.$qrCode->getContentType());
$qrCode->render();

// save it to a file
$qrCode->save('qrcode.png');

// or create a response object
$response = new Response($qrCode->get(), 200, array('Content-Type' => $qrCode->getContentType()));

Symfony

You can use EndroidQrCodeBundle to integrate this service in your Symfony application.
