There are plenty of datetime functions in PHP that may be useful to you. Here is a list of many of them, date_add and date_parse could both be useful to you depending on how you want to do it.

As darkagn says, there are loads of ways in which you could do it. You could use strtotime, keep everything within date functions or do a simple explode and mktime:

$bits = explode("-",$date);
$newdate = date('d-m-Y',mktime(0,0,0,intval($bits[1]) + 17,$bits[0],$bits[2]));

//this approach has the advantage of correctly dealing with overflows( month + 17).

ardav, thank you.

I used this code:

list($year,$month,$day) = explode("-",$row['prisonDate']);
$d = mktime(0,0,0,$month,$day,$year);
$dis = date("Y-m-d",strtotime("+".$discount ."months",$d));

And it's work fun
