What are some common methods for generating QR codes using PHP?

Generating QR codes using PHP can be achieved by using libraries such as PHP QR Code or Endroid QR Code. These libraries provide functions to easily create QR codes with different content types such as URLs, text, or contact information. By integrating these libraries into your PHP code, you can generate QR codes dynamically based on user input or predefined data. 

// Using PHP QR Code library
include 'qrlib.php';

// QR code content
$content = 'https://www.example.com';

// Output QR code image
QRcode::png($content);
```

```php
// Using Endroid QR Code library
require_once 'vendor/autoload.php';

use Endroid\QrCode\QrCode;

// QR code content
$content = 'Hello, World!';

// Create QR code instance
$qrCode = new QrCode($content);

// Output QR code image
header('Content-Type: '.$qrCode->getContentType());
echo $qrCode->writeString();
