How to get the next 12 months from this month?

What I'm using now is:

PHP Code

  
   for ($i =1; $i <=12; $i + +) {    $nextdate = date ("Y-m", Strtotime ("+ $i Month"));    Echo '
'. $nextdate;}

Seems to be no problem, can print but found that March is repeated, I do not know why.

------Solution--------------------
Because your month is 28 days in 30 days, so it's not right to wait until February.
------Solution--------------------

PHP Code

The parameter represents a lot of months, you can also modify the Start function c ($num =) {    $temp = array () for the specified date;    $nowtime = strtotime (Date (' Y-m ', Time ()). '-1 ');    while ($num >0) {        $num--;        $nowtime = Strtotime (' +1 month ', $nowtime);        $temp []  = Date (' y-m ', $nowtime);    }    Unset ($num, $nowtime);    return $temp;} Print_r (c ());
