How can CSS be utilized in PHP to ensure consistent background colors for specific table cells, regardless of browser or printing settings?

To ensure consistent background colors for specific table cells in PHP, you can use inline CSS styles within the HTML table cells. This will override any browser or printing settings, ensuring that the background color remains consistent across different environments.

<?php
echo "<table>";
echo "<tr>";
echo "<td style='background-color: #ff0000;'>Cell 1</td>";
echo "<td style='background-color: #00ff00;'>Cell 2</td>";
echo "</tr>";
echo "</table>";
?>
