What are the limitations of using PHP in a non-frame website layout?

When using PHP in a non-frame website layout, one limitation is that PHP cannot directly control the layout and styling of the website. To solve this, you can use PHP to dynamically generate HTML content based on data or user input, but the actual layout and styling should be handled using HTML and CSS.

<?php
// PHP code to generate dynamic content
echo "<div class='content'>";
echo "<h1>Welcome to our website!</h1>";
echo "<p>This is some dynamic content generated using PHP.</p>";
echo "</div>";
?>
