How can switching between PHP and HTML frequently impact code readability and maintainability?

Switching between PHP and HTML frequently can impact code readability and maintainability by making the code harder to follow and debug. To improve this, it's recommended to separate PHP logic from HTML markup by using a templating engine like Twig or Blade. This approach helps to keep the code organized and easier to maintain. 

<?php
// Using Twig templating engine to separate PHP logic from HTML markup
require_once 'vendor/autoload.php';

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

echo $twig->render('index.html', ['name' => 'John Doe']);
?>
