Sure, here's an example code for generating a QR code in Laravel using the "QrCode" package:
First, install the package using composer:
Code:
composer require simple-qrcode/simple-qrcode
Then, in your controller or wherever you want to generate the QR code, add the following code:
PHP:
use SimpleSoftwareIO\QrCode\Facades\QrCode;
public function generateQRCode()
{
$qrCode = QrCode::generate('Hello, world!'); // Replace with your content
return response($qrCode)->header('Content-type','image/png');
}
This will generate a PNG image of the QR code with the content "Hello, world!". You can change the content to whatever you want.
To generate a barcode, you can use the "BarCode" package:
Code:
composer require milon/barcode
And then in your controller:
PHP:
use Milon\Barcode\DNS1D;
public function generateBarCode()
{
$barcode = new DNS1D;
$barcode->getBarcodeHTML('1234567890', 'C39');
return view('barcode', ['barcode' => $barcode]);
}
This will generate a Code 39 barcode with the content "1234567890". You can change the content and barcode type as needed.
Now, to scan the QR code or barcode using a mobile phone, you just need a QR code or barcode scanner app. There are many free ones available for both Android and iOS. Simply point your phone's camera at the code and the app will do the rest.
