What are the potential pitfalls of embedding PHP code within PHP code?

Embedding PHP code within PHP code can lead to confusion, readability issues, and potential errors. To avoid these pitfalls, it's recommended to separate PHP logic from HTML markup by using a templating engine like Twig or Blade. This approach improves code organization, makes it easier to maintain and debug, and enhances overall code quality.

// Example of using Twig templating engine to separate PHP logic from HTML markup
$loader = new \Twig\Loader\FilesystemLoader('/path/to/templates');
$twig = new \Twig\Environment($loader);

// Render a template file with variables
echo $twig->render('index.html', ['name' => 'John Doe']);
