Are there best practices for organizing and structuring PHP code to handle navigation elements on both the left and right sides of a webpage?

When organizing and structuring PHP code to handle navigation elements on both the left and right sides of a webpage, it is best practice to create separate PHP files for each side and then include them in the main template file using PHP include statements. This approach helps to keep the code clean, modular, and easily maintainable.

// left_navigation.php
<nav>
    <!-- Left navigation elements -->
</nav>

// right_navigation.php
<nav>
    <!-- Right navigation elements -->
</nav>

// main_template.php
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Website Title</title>
</head>
<body>
    <?php include 'left_navigation.php'; ?>
    
    <main>
        <!-- Main content of the webpage -->
    </main>
    
    <?php include 'right_navigation.php'; ?>
</body>
</html>
