How can dynamic site generation be improved by using Include in PHP?

Dynamic site generation can be improved by using the "include" function in PHP to break down the code into smaller, reusable components. This helps in organizing the code, making it easier to maintain and update. By including separate files for header, footer, sidebar, and other common elements, the overall code becomes more modular and efficient.

<?php
//index.php

include 'header.php';

// main content here

include 'sidebar.php';

// footer content here
?>
