What are some best practices for organizing PHP code within an HTML structure?

When organizing PHP code within an HTML structure, it is important to separate logic from presentation to maintain a clean and maintainable codebase. One common approach is to use a templating system like PHP's built-in `include` or `require` functions to separate PHP logic into separate files and then include them within the HTML structure as needed. 

<!-- index.php -->
<!DOCTYPE html>
<html lang="en">
<head>
    <title>My Website</title>
</head>
<body>
    <header>
        <?php include 'header.php'; ?>
    </header>
    
    <main>
        <?php include 'content.php'; ?>
    </main>
    
    <footer>
        <?php include 'footer.php'; ?>
    </footer>
</body>
</html>
