What are the potential pitfalls of using includes in PHP to build a website layout, and how can they be avoided?

One potential pitfall of using includes in PHP to build a website layout is that it can lead to a cluttered directory structure with numerous include files. This can make it difficult to manage and maintain the codebase. To avoid this issue, consider using a template engine like Twig or Blade that allows for more structured and reusable code.

// Example using Twig template engine to avoid cluttered include files

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

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

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

// Render a template
echo $twig->render('layout.twig', ['content' => 'Hello, World!']);
