How can PHP users ensure they include the correct year when calculating end dates based on months?

When calculating end dates based on months in PHP, users should ensure they include the correct year by checking if the resulting month exceeds 12. If the resulting month is greater than 12, increment the year accordingly. This ensures that the end date is accurately calculated with the correct year.

php 
$start_date = '2022-10-15';
$months_to_add = 5;

$end_date = date('Y-m-d', strtotime($start_date . ' + ' . $months_to_add . ' months'));

list($year, $month, $day) = explode('-', $end_date);

if ($month > 12) {
    $year += floor($month / 12);
    $month = $month % 12;
}

$end_date = date('Y-m-d', strtotime("$year-$month-$day"));

echo $end_date;
