What are the differences between using HTML and PHP for website customization?

When customizing a website, HTML is used for structuring the content and layout, while PHP is used for dynamic functionalities and server-side processing. HTML is static and used for creating the basic structure of web pages, while PHP allows for dynamic content generation, database interactions, and user input processing. By combining both HTML and PHP, developers can create interactive and personalized websites.

<?php
// PHP code for website customization
echo "<html>";
echo "<head>";
echo "<title>Customized Website</title>";
echo "</head>";
echo "<body>";
echo "<h1>Welcome to our website!</h1>";
echo "<p>This website is customized using PHP.</p>";
echo "</body>";
echo "</html>";
?>
