1. Installing the chillerlan-php-qrcode Library
Before we dive into generating QR codes, we need to install the chillerlan-php-qrcode library. Follow these steps to set up the library using Composer

composer require chillerlan/php-qrcode

2. Generating a Basic QR Code
To create a basic QR code, you can use the following code as a starting point:

<?php
require 'vendor/autoload.php';

use chillerlan\QRCode\QRCode;
use chillerlan\QRCode\QROptions;
 $opti QROptions([
    'version'      => 5,
    'outputType'   => QRCode::OUTPUT_IMAGE_PNG,
    'eccLevel'     => QRCode::ECC_L,
    'imageBase64'  => false,
]);

$qrCode = new QRCode($options);

$qrCode->render('https://example.com', 'path/to/save.png');

This code generates a QR code that links to 'https://example.com' and saves it as a PNG image.

3. Customizing QR Codes
You can customize QR codes by adjusting various parameters in the QROptions. For instance, you can change the version, output type, error correction level, and more. Explore the documentation for a full list of customization options.

4. Saving QR Codes to Disk
In the code example above, we saved the QR code as a PNG image. You can change the 'path/to/save.png' to the desired path and filename where you want to save your QR code.

5. Implementing QR Codes in Your PHP Application
To use the generated QR code in your PHP application, simply include the generated image in your HTML with an <img> tag.
