What are the best practices for using counters and modulo in PHP to determine output placement?

When using counters and modulo in PHP to determine output placement, it is important to ensure that the counter starts at 0 and increments with each iteration. Modulo (%) can be used to calculate the remainder of the counter divided by the desired number of columns or rows, which can then be used to determine the placement of the output. 

// Initialize counter
$counter = 0;

// Define number of columns
$columns = 3;

// Loop through data
foreach ($data as $item) {
    // Calculate placement based on counter and columns
    $placement = $counter % $columns;

    // Output item with placement
    echo '<div class="column-' . $placement . '">' . $item . '</div>';

    // Increment counter
    $counter++;
}
