What are the potential pitfalls of using inline code in PHP scripts?

Using inline code in PHP scripts can make the code harder to read and maintain, as it mixes HTML and PHP logic together. It can also lead to security vulnerabilities if user input is not properly sanitized or validated. To avoid these pitfalls, it's recommended to separate PHP logic from HTML presentation by using a templating engine like Twig or by implementing MVC architecture. 

// Example of separating PHP logic from HTML presentation using Twig templating engine
// Install Twig using Composer: composer require twig/twig

require_once 'vendor/autoload.php';

$loader = new \Twig\Loader\FilesystemLoader('templates');
$twig = new \Twig\Environment($loader);

// Define variables for the template
$variables = [
    'name' => 'John Doe',
    'age' => 30
];

// Render the template
echo $twig->render('index.html', $variables);
