Monthly recur with PHP - php

Question

I have a two dates. start date and end date. Using those dates i have to find recur dates.
example:
(1) start date = 2014-01-01
end date = 2014-05-01
expected output:
2014-01-01
2014-02-01
2014-03-01
2014-04-01
2014-05-01
(2) start date = 2014-01-31
end date = 2014-05-01
expected output:
2014-01-31
2014-02-28
2014-03-31
2014-04-30
means do not skip month, if month is skip in that case use last day of month. how to achive this thing?
I am using following code but i added 1 month in date so it skip the month:
$start = strtotime($start_date);
$end = strtotime($end_date);
$total_dates = array();
for($i=$start; $i<=$end;)
{
$date = date('Y-m-d',$start);
if($i>$start)
{
$next_date = date('Y-m-d',strtotime($date . "+1 month"));
$start = strtotime($next_date);
}
else
{
$next_date = date('Y-m-d',$start);
}
$total_dates[] = $next_date;
$date1 = new DateTime($date);
$newdate = date('Y-m-d',strtotime($date . "+1 month"));
$date2 = new DateTime($newdate);
$diff = $date2->diff($date1)->format("%a");
/* Find diff between two dates */
$i = (($i*1)+(86400*$diff)); //seconds in 1month
}
print_r($total_dates);
so in short:
start date = 2014-01-01
end date = 2014-05-01
expected output:
2014-01-31
2014-02-28
2014-03-31
2014-04-30
current output:
2014-01-31
2015-03-03
2015-04-03

check this
$start_date = '2015-01-31';
$end_date = '2016-06-01';
$start_date=date('Y-m-1', strtotime($start_date));
$diff = abs(strtotime($end_date) - strtotime($start_date));
$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
if($years>0){$loop=$years*12+$months;}else{$loop=$months;}
for($i=1; $i<=$loop+1;$i++)
{
$total_dates[] =$a= date('Y-m-t', strtotime($start_date));
$start_date = date('Y-m-d',strtotime($start_date . "+1 month"));
}
print_r($total_dates);
//output Array ( [0] => 2015-01-31 [1] => 2015-02-28 [2] => 2015-03-31 [3] => 2015-04-30 [4] => 2015-05-31 [5] => 2015-06-30 [6] => 2015-07-31 [7] => 2015-08-31 [8] => 2015-09-30 [9] => 2015-10-31 [10] => 2015-11-30 [11] => 2015-12-31 [12] => 2016-01-31 [13] => 2016-02-29 [14] => 2016-03-31 [15] => 2016-04-30 [16] => 2016-05-31 [17] => 2016-06-30 )

Try this...
<?php
$start_date = "2014-01-01";
$end_date = "2014-05-01";
$d = date_parse_from_format("Y-m-d", $start_date);
$start= $d["month"];
$d1 = date_parse_from_format("Y-m-d", $end_date);
$end= $d1["month"];
$array=array();
$array[]=date('Y-m-t', strtotime($start_date));
for($i=$start;$i<$end;$i++)
{
$str=explode("-",$start_date);
$mon=$str[1]+$i;
$newdate=$str[0]."-".$mon."-".$str[2];
$array[]=date('Y-m-t', strtotime($newdate));
}
print_r($array);
output:
2014-01-31
2014-02-28
2014-03-31
2014-04-30
2014-05-31

Use PHP date/time functions with relative interval formats:
http://php.net/manual/en/datetime.formats.relative.php
You can provide intervals like "last day of next month" or "last sat of July 2008", adding/subtracting this interval from the referenced date.
