What are the potential drawbacks of using eval() function in PHP for template rendering?

Using the eval() function in PHP for template rendering can introduce security vulnerabilities, as it allows for arbitrary code execution. This can lead to potential attacks such as code injection or remote code execution. To mitigate this risk, it is recommended to use alternative methods for template rendering, such as PHP's built-in templating engines like Twig or Blade. 

// Example of using Twig for template rendering instead of eval()

// Include the Twig autoload file
require_once 'vendor/autoload.php';

// Specify the template directory
$loader = new \Twig\Loader\FilesystemLoader('templates');

// Initialize Twig environment
$twig = new \Twig\Environment($loader);

// Render a template
echo $twig->render('index.html', ['name' => 'John Doe']);
