# QR Code *By [endroid](https://endroid.nl/)* [](https://packagist.org/packages/endroid/qr-code) [](http://travis-ci.org/endroid/qr-code) [](https://packagist.org/packages/endroid/qr-code) [](https://packagist.org/packages/endroid/qr-code) [](https://packagist.org/packages/endroid/qr-code) [](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=RGH86QN825TWN) This library helps you generate QR codes in a jiffy. ## Installation Use [Composer](https://getcomposer.org/) to install the library. ``` bash $ composer require endroid/qr-code ``` ## Basic usage ```php use Endroid\QrCode\QrCode; $qrCode = new QrCode('Life is too short to be generating QR codes'); header('Content-Type: '.$qrCode->getContentType()); echo $qrCode->writeString(); ``` ## Advanced usage ```php use Endroid\QrCode\ErrorCorrectionLevel; use Endroid\QrCode\LabelAlignment; use Endroid\QrCode\QrCode; use Endroid\QrCode\Response\QrCodeResponse; // Create a basic QR code $qrCode = new QrCode('Life is too short to be generating QR codes'); $qrCode->setSize(300); // Set advanced options $qrCode->setWriterByName('png'); $qrCode->setMargin(10); $qrCode->setEncoding('UTF-8'); $qrCode->setErrorCorrectionLevel(ErrorCorrectionLevel::HIGH); $qrCode->setForegroundColor(['r' => 0, 'g' => 0, 'b' => 0, 'a' => 0]); $qrCode->setBackgroundColor(['r' => 255, 'g' => 255, 'b' => 255, 'a' => 0]); $qrCode->setLabel('Scan the code', 16, __DIR__.'/../assets/fonts/noto_sans.otf', LabelAlignment::CENTER); $qrCode->setLogoPath(__DIR__.'/../assets/images/symfony.png'); $qrCode->setLogoWidth(150); $qrCode->setRoundBlockSize(true); $qrCode->setValidateResult(false); // Directly output the QR code header('Content-Type: '.$qrCode->getContentType()); echo $qrCode->writeString(); // Save it to a file $qrCode->writeFile(__DIR__.'/qrcode.png'); // Create a response object $response = new QrCodeResponse($qrCode); ```  ## Built-in validation reader You can enable the built-in validation reader (disabled by default) by calling setValidateResult(true). This validation reader does not guarantee that the QR code will be readable by all readers but it helps you provide a minimum level of quality. The readability of a QR code is primarily determined by the size, the input length, the error correction level and any possible logo over the image so you can tweak these parameters if you are looking for optimal results. You can also check $qrCode->getRoundBlockSize() value to see if block dimensions are rounded so that the image is more sharp and readable. Take note that the validator can consume quite amount of additional resources. ## Symfony integration The [endroid/qr-code-bundle](https://github.com/endroid/qr-code-bundle) integrates the QR code library in Symfony for an even better experience. * Configure your defaults (like image size, default writer etc.) * Generate QR codes quickly from anywhere via the factory service * Generate QR codes directly by typing an URL like /qr-code/\<text>.png?size=300 * Generate QR codes or URLs directly from Twig using dedicated functions Read the [bundle documentation](https://github.com/endroid/qr-code-bundle) for more information. ## Versioning Version numbers follow the MAJOR.MINOR.PATCH scheme.
