How can the modulo operator be utilized to achieve the desired output format in PHP?

When dealing with formatting output in PHP, the modulo operator (%) can be used to determine if a certain condition is met and then adjust the output accordingly. For example, if you want to alternate the background color of table rows, you can use the modulo operator to check if the row number is even or odd and apply different styles accordingly. 

// Example of using the modulo operator to alternate row colors in a table
echo '<table>';
for ($i = 1; $i <= 10; $i++) {
    if ($i % 2 == 0) {
        echo '<tr style="background-color: #f2f2f2;"><td>Row ' . $i . '</td></tr>';
    } else {
        echo '<tr style="background-color: #ffffff;"><td>Row ' . $i . '</td></tr>';
    }
}
echo '</table>';
