PHP: Add X Months to a Date

You can quite easily calculate that date using strtotime() and the following syntax:

$d = time();

echo date("d.m.Y", strtotime("+1 Months", $d));
echo date("d.m.Y", strtotime("+3 Months", $d));

In this example, first, we are determining the current date with time(). After that, we are adding either one month or three months to this date, so that we get the date into one or three months from today.

Instead of taking the current date, of course, we can also take any other arbitrary other initial date.
