How can the use of the Modulo Operator in PHP help in the context of generating tables from MySQL data?

When generating tables from MySQL data in PHP, we may want to alternate row colors to improve readability. One way to achieve this is by using the Modulo Operator (%) to determine if the current row is even or odd, and then apply different styling accordingly. 

// Assuming $result contains the MySQL data
$row_count = 0;

while($row = mysqli_fetch_assoc($result)) {
    $row_count++;
    if($row_count % 2 == 0) {
        echo '<tr style="background-color: #f2f2f2;">';
    } else {
        echo '<tr>';
    }
    
    // Output table data here
    
    echo '</tr>';
}
