How to find first day of the next month and remaining days till this date with PHP

Question

How can I find first day of the next month and the remaining days till this day from the present day?

Thank you

Answer 1

$firstDayNextMonth = date('Y-m-d', strtotime('first day of next month'));

For getting first day after two months from current

$firstDayAfterTwoMonths = date('Y-m-d', strtotime('first day of +2 month'));
