What are the advantages of using PHP to dynamically generate web pages instead of static HTML pages?

Using PHP to dynamically generate web pages allows for easier maintenance and updates, as content can be pulled from databases or external sources. It also enables the creation of interactive and personalized content based on user input or session data. Additionally, PHP can help improve website performance by allowing for the reuse of code snippets and templates.

<?php
// Example PHP code snippet for dynamically generating a web page
$dynamic_content = "Hello, world!";
echo "<html><head><title>Dynamic Web Page</title></head><body>";
echo "<h1>$dynamic_content</h1>";
echo "</body></html>";
?>
