How can PHP be used to ensure responsive design in displaying data on a website?

To ensure responsive design in displaying data on a website using PHP, you can use media queries to adjust the layout based on the screen size. By setting different styles for different screen sizes, you can make sure that the data is displayed in a user-friendly way on various devices.

<?php
echo '<style>';
echo '@media only screen and (max-width: 600px) {';
echo '  /* CSS styles for small screens */';
echo '}';
echo '@media only screen and (min-width: 601px) {';
echo '  /* CSS styles for larger screens */';
echo '}';
echo '</style>';
?>
