In PHP development, how can the separation of concerns between HTML and PHP elements be maintained for better code organization and readability?

To maintain the separation of concerns between HTML and PHP elements in PHP development, it is recommended to use a templating engine like Twig or Blade. These templating engines allow you to separate the HTML structure from the PHP logic, resulting in cleaner and more organized code. By using these tools, you can easily manage your templates, improve readability, and make your code more maintainable.

// Using Twig templating engine
require_once 'vendor/autoload.php';

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

// Render the template with variables
echo $twig->render('index.html', ['title' => 'Hello World']);
