Simple PHP script that generates a QR code using the popular library called PHP QR Code. This library is open-source and easy to use. Follow these steps to create your QR code generator.
You can download the library from GitHub or directly using Composer if your project supports it.
If using Composer, run this command:
composer require endroid/qr-code
Create a new PHP file, for example, generate_qr.php, and add the following code:
<?php
require 'vendor/autoload.php'; // Ensure you have the autoload from Composer if using Composer
use Endroid\QrCode\QrCode;
use Endroid\QrCode\ErrorCorrectionLevel;
use Endroid\QrCode\LabelAlignment;
// Check if the form is submitted
if (isset($_POST['text'])) {
$text = $_POST['text']; // Get the text from the form
// Create a QR code
$qrCode = new QrCode($text);
$qrCode->setErrorCorrectionLevel(ErrorCorrectionLevel::HIGH());
$qrCode->setSize(300);
$qrCode->setMargin(10);
// Generate and save the QR code to a file
header('Content-Type: image/png');
echo $qrCode->writeString(); // Output the QR code as a PNG image
exit;
}
?>
