What is the best approach to increment every 9th value in a column in a PHP-generated table?

To increment every 9th value in a column in a PHP-generated table, you can loop through the data and use a counter variable to keep track of the position. When the counter reaches a multiple of 9, you can increment the value before outputting it in the table. 

<?php
$data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]; // Sample data
$counter = 0;

echo "<table>";
foreach ($data as $value) {
    if (($counter + 1) % 9 == 0) {
        $value++; // Increment every 9th value
    }
    echo "<tr><td>$value</td></tr>";
    $counter++;
}
echo "</table>";
?>
