What are the best practices for organizing and structuring PHP includes to prevent duplication and ensure smooth functionality?

When organizing and structuring PHP includes, it is important to prevent duplication of code to ensure smooth functionality. One way to achieve this is by creating separate PHP files for reusable code snippets and including them where needed using include_once or require_once functions. This helps in maintaining a clean and organized codebase, making it easier to manage and update in the future. 

// header.php
<html>
<head>
    <title>My Website</title>
</head>
<body>
    <header>
        <h1>Welcome to My Website</h1>
    </header>

// footer.php
    <footer>
        <p>© <?php echo date('Y'); ?> My Website</p>
    </footer>
</body>
</html>

// index.php
<?php
include_once 'header.php';
?>
<main>
    <p>Welcome to my homepage!</p>
</main>
<?php
include_once 'footer.php';
?>
