How can including external files like HTML templates improve PHP code organization and readability?

Including external files like HTML templates in PHP code can improve organization and readability by separating the presentation layer from the logic layer. This allows for cleaner and more maintainable code as the HTML templates can be easily updated or swapped out without affecting the PHP logic. Additionally, it promotes code reusability as the same template can be included in multiple pages. 

<?php
// index.php
include 'header.php';
echo '<h1>Welcome to my website!</h1>';
include 'footer.php';
?>
