What are the potential pitfalls of using PHP to output HTML content?

One potential pitfall of using PHP to output HTML content is the mixing of PHP logic with HTML markup, which can make the code harder to read and maintain. To solve this issue, it's recommended to separate the PHP logic from the HTML markup by using a template engine like Twig or Blade. This allows for cleaner code organization and easier maintenance in the long run. 

<?php
// Example using Twig template engine
require_once 'vendor/autoload.php';

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

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