How can embedded frames or iframes be utilized to display dynamic content on a webpage using PHP?

Embedded frames or iframes can be utilized to display dynamic content on a webpage using PHP by creating a PHP script that generates the dynamic content and then embedding this script within an iframe in the HTML code of the webpage. This allows the dynamic content to be loaded and displayed independently of the main webpage, providing a seamless user experience.

<?php
// dynamic_content.php
echo "This is dynamic content generated by PHP.";
?>

<!-- index.html -->
<!DOCTYPE html>
<html>
<head>
    <title>Dynamic Content Example</title>
</head>
<body>
    <h1>Main Page</h1>
    <iframe src="dynamic_content.php" width="400" height="300"></iframe>
</body>
</html>
