Are there any common pitfalls to avoid when trying to create a design using PHP?

One common pitfall to avoid when creating a design using PHP is mixing HTML and PHP code too much, leading to messy and hard-to-maintain code. To solve this, it's recommended to separate the PHP logic from the HTML markup by using a template engine like Twig or Blade. Example: 

<?php
// Include the Twig library
require_once 'vendor/autoload.php';

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

// Define data to pass to the template
$data = [
    'title' => 'Welcome to my website',
    'content' => 'This is some sample content',
];

// Render the template with the data
echo $twig->render('index.html', $data);
?>
