What are the potential benefits of separating HTML and PHP files in web development?

Separating HTML and PHP files in web development can make the code more organized, easier to maintain, and improve readability. It also allows for better separation of concerns, making it easier for front-end developers to work on the HTML without needing to understand the PHP logic behind it.

// index.php
<?php
include 'header.php';
?>

<h1>Welcome to my website!</h1>

<?php
include 'footer.php';
?>
