How can PHP developers ensure proper separation of concerns when working with graphics and HTML elements?

To ensure proper separation of concerns when working with graphics and HTML elements in PHP, developers can utilize a templating engine like Twig. By separating the logic and presentation layers, developers can keep their PHP code clean and organized, making it easier to maintain and update in the future.

// Using Twig templating engine for proper separation of concerns
require_once 'vendor/autoload.php';

$loader = new Twig_Loader_Filesystem('templates');
$twig = new Twig_Environment($loader);

$template = $twig->load('index.html.twig');

$data = array(
    'title' => 'My Website',
    'image' => 'path/to/image.jpg',
    'content' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'
);

echo $template->render($data);
