How can I effectively integrate HTML design created in Photoshop with PHP functionality to ensure a visually appealing website?

To effectively integrate HTML design created in Photoshop with PHP functionality, you can use PHP includes to separate the design and functionality. Create separate PHP files for the header, footer, and any other repeating elements, and then include them in your main PHP files where necessary. This will help maintain a visually appealing website while ensuring seamless integration of PHP functionality.

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

<!-- Your HTML design content here -->

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