如何使用time（）函数在php中使用timestamp获取下个月

Question

i can get current timestamp with time(); How can i add him and get next month? So how can i get next month with timestamp?

I try with mktime and strtotime but none works.

Example:

$date = time();
$month = date('m', $date);

how to get next mont?

If you just add one month, you'll end up skipping months now and then. For example, what is 31th of May plus one month? Is it the last of June or is it the first of July? In PHP, strtotime will take the latter approach and give you the first day of July.

If you just want to know the month number, this is a simple approach:

$month = date('n') + 1;
if($month > 12) {
  $month = $month % 12;
}

or for infinite flexibility (if you need to configure how many months to add or subtract):

$add = 1;
$month = ((date('n') - 1 + $add) % 12) + 1;
