Are there any common pitfalls to avoid when integrating PHP into web development for design purposes?

One common pitfall to avoid when integrating PHP into web development for design purposes is mixing PHP logic with HTML code. This can lead to messy and hard-to-maintain code. To solve this, it is recommended to separate PHP logic from HTML code by using templates or frameworks like Laravel or Symfony. 

<?php
// Separate PHP logic from HTML code using templates
// Example using Laravel Blade template engine

// In controller
$data = ['title' => 'Welcome'];
return view('welcome', $data);

// In view (welcome.blade.php)
<!DOCTYPE html>
<html>
<head>
    <title>{{ $title }}</title>
</head>
<body>
    <h1>Welcome</h1>
</body>
</html>
