How can one ensure that the result of calculating the next month in PHP accounts for months with fewer than 30 or 31 days?

When calculating the next month in PHP, it is important to account for months with fewer than 30 or 31 days by using the `DateTime` class and its `modify` method. By adding one month to the current date and then adjusting it to the last day of the month, we can ensure that the result is accurate even for months with varying lengths. 

$currentDate = new DateTime();
$nextMonth = clone $currentDate;
$nextMonth->modify('+1 month');
$nextMonth->modify('last day of this month');

echo $nextMonth->format('Y-m-d');
