What are the advantages and disadvantages of using PHP to dynamically generate pages compared to static pages?

When using PHP to dynamically generate pages, the main advantage is the ability to easily update content without having to manually edit each individual page. This can save time and effort, especially for websites with a large number of pages. However, dynamically generated pages can be slower to load compared to static pages, as they require server-side processing each time a page is accessed.

<?php
// Dynamically generate a page with PHP
echo "<html>";
echo "<head><title>Welcome</title></head>";
echo "<body>";
echo "<h1>Welcome to our website!</h1>";
echo "<p>This page was dynamically generated using PHP.</p>";
echo "</body>";
echo "</html>";
?>
