First make sure you have Composer installed. Then follow these steps: Create a new directory for your project and navigate into it. Create a new composer.json file and add the following content: { require: { endroid/qr-code: 3.10.0 } } Run composer install in the project directory to install the required dependencies. Create a new PHP file e.g. payment.php  and add the following code: setSize($size); return $qrCode->writeDataUri(); } // Example usage $paymentAmount = 100.00; // The payment amount $paymentDescription = Payment for Product XYZ; // The payment description // Format the payment data (you may need to adjust this based on your payment integration) $paymentData = Amount: $paymentAmount
Description: $paymentDescription; // Generate the QR code image $qrCodeDataUri = generateQRCode($paymentData); // Display the QR code image echo ' '; In this example we use the generateQRCode function to generate the QR code using the QrCode class from the QR Code Generator library. You can adjust the payment amount and description based on your requirements. When you run the payment.php file it will display the generated QR code image which the user can then scan and use for payment. Make sure to include any additional payment processing logic and integrate it with your payment gateway as needed. Note: This example is a basic implementation for generating a QR code for payment integration. Depending on your specific payment provider and integration requirements you may need to adjust the code accordingly. Remember to secure your payment integration by implementing proper validation encryption and following best practices recommended by your payment service provider. I hope this helps you get started with QR code-based payment integration in PHP!
