Are there any best practices recommended for organizing PHP code for output customization?

When organizing PHP code for output customization, it is recommended to separate the presentation logic from the business logic. This can be achieved by using templates or a template engine like Twig. By keeping the HTML markup separate from the PHP code, it makes it easier to make changes to the output without affecting the underlying logic.

// Example of organizing PHP code using Twig for output customization

// Include Twig autoloader
require_once 'vendor/autoload.php';

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

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

// Define variables to pass to the template
$data = [
    'title' => 'Welcome to our website',
    'content' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'
];

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