What is the significance of using the Modulo operator in PHP when formatting tabular data?

When formatting tabular data in PHP, using the Modulo operator can help alternate row colors to improve readability for users. By using the Modulo operator, we can easily determine if a row is even or odd and apply different CSS styles accordingly. This can make the data more visually appealing and easier to read. 

<?php
// Loop through tabular data
foreach($data as $index => $row) {
    // Apply different CSS class based on odd/even row
    $class = ($index % 2 == 0) ? 'even' : 'odd';
    
    // Output table row with alternating row colors
    echo "<tr class='$class'>";
    foreach($row as $cell) {
        echo "<td>$cell</td>";
    }
    echo "</tr>";
}
?>
