What are the potential issues with integrating PHP and CSS for setting background colors dynamically?

One potential issue with integrating PHP and CSS for setting background colors dynamically is that it can lead to messy and hard-to-maintain code. To solve this, you can separate the PHP logic from the CSS styling by using inline styles or CSS classes that are dynamically generated by PHP.

<?php
// PHP logic to determine background color
$background_color = 'blue';

// Output CSS with inline styles
echo '<style>';
echo 'body { background-color: ' . $background_color . '; }';
echo '</style>';
?>
