php - How to get same day of the next months? -

for recurring payment (monthly) need same date of next months, o.n., 1st of every month or 15th of every month (monthly)

but it's should maintain 31,30,28 , 29th dates.

e.g., 1/31/2014(first recurring payment date) , 2/28/2014 or 2/29/2014(2nd date), 3/31/2014 (3rd ) ... on )

e.g .1/15/2014 , 2/15/2014 , 3/15/2014 , 4/15/2014 , 5/15/2014 .. on

you can use dateperiod class:

this works partially:

there issue when d >= 29, months after february have payment registered last day.

<?php error_reporting(e_all); $begin = new datetime('2014-01-29'); $lastdayinterval = dateinterval::createfromdatestring('last day of next month'); $monthinterval = new dateinterval('p1m'); $lastdays = new dateperiod(clone $begin, $lastdayinterval, 12,                             dateperiod::exclude_start_date); $addedmonthdays = new dateperiod(clone $begin, $monthinterval, 12,                             dateperiod::exclude_start_date);  $lastdaysarray = array(); foreach ($lastdays $lastday) {     $lastdaysarray[] = $lastday; }  $addedmonthdaysarray = array(); foreach ($addedmonthdays $addedmonthday) {     $addedmonthdaysarray[] = $addedmonthday; }  ($i = 0; $i < 12; $i++) {     if ($addedmonthdaysarray[$i] > $lastdaysarray[$i]) {         echo $lastdaysarray[$i]->format('y-m-d') . php_eol;     } else {         echo $addedmonthdaysarray[$i]->format('y-m-d') . php_eol;     } } 

outputs:

2014-02-28 2014-03-31 2014-04-30 2014-05-31 2014-06-30 2014-07-31 2014-08-31 2014-09-30 2014-10-31 2014-11-30 2014-12-31 2015-01-31 

with:

$begin = new datetime('2014-01-28'); 

it outputs:

2014-02-28 2014-03-28 2014-04-28 2014-05-28 2014-06-28 2014-07-28 2014-08-28 2014-09-28 2014-10-28 2014-11-28 2014-12-28 2015-01-28
