How can the Modulo Operator be applied in a loop to control the output of table rows in PHP?

When outputting table rows in a loop in PHP, you can use the modulo operator (%) to control the number of columns per row. By using the modulo operator with a specific number (e.g. 3 for 3 columns per row), you can determine when to start a new row in the table. 

<?php
$rows = 10;
$columns_per_row = 3;

echo '<table>';
for ($i = 1; $i <= $rows; $i++) {
    if (($i - 1) % $columns_per_row == 0) {
        echo '<tr>';
    }
    echo '<td>Row ' . $i . '</td>';
    if ($i % $columns_per_row == 0 || $i == $rows) {
        echo '</tr>';
    }
}
echo '</table>';
?>
