Last day of each month within a date range in php - php

Question

How to get last day of each month within a date range in PHP?
Input:
$startdate = '2013-01-15'
$enddate = '2013-03-15'
The output that I want is:
2013-01-31 End date of January
2013-02-28 End date of February
2013-03-15 *End date of March is '2013-03-31' but the end date is '2013-03-15' .
So I want 2013-03-15.
How can I do that?

Answer 1

In the future, try to write the code yourself. If you are stuck with a specific part you can request help. Exception for this one time:
<?php
$startdate = new DateTime('2013-01-15');
$enddate = new DateTime('2013-04-15');
$year = $startdate->format('Y');
$start_month = (int)$startdate->format('m');
$end_month = (int)$enddate->format('m');
for ( $i=$start_month; $i<$end_month; $i++) {
$date = new DateTime($year.'-'.$i);
echo $date->format('Y-m-t').' End date of '.$date->format('F');
}
echo $enddate->format('Y-m-d');
Will output:
2013-01-31 End date of January
2013-02-28 End date of February
2013-03-31 End date of March
2013-04-15
Note that this does not work if the start and end dates have a different year. I have left this as an exercise.

function get_months($date1, $date2) {
$time1 = strtotime($date1);
$time2 = strtotime($date2);
$my = date('mY', $time2);
$months = array(date('Y-m-t', $time1));
$f = '';
while($time1 < $time2) {
$time1 = strtotime((date('Y-m-d', $time1).' +15days'));
if(date('F', $time1) != $f) {
$f = date('F', $time1);
if(date('mY', $time1) != $my && ($time1 < $time2))
$months[] = date('Y-m-t', $time1);
}
}
$months[] = date('Y-m-d', $time2);
return $months;
}
$myDates = get_months('2005-01-20', '2005-11-25');
$myDates will have the output you want. It will work even if years are different. Logic is from this URL

I'm little changed the function:
function get_months($date1, $date2) {
$time1 = strtotime($date1);
$time2 = strtotime($date2);
$my = date('mY', $time2);
$f = '';
while($time1 < $time2) {
$time1 = strtotime((date('Y-m-d', $time1).' +15days'));
if(date('F', $time1) != $f) {
$f = date('F', $time1);
if(date('mY', $time1) != $my && ($time1 < $time2))
$months[] = array(date('Y-m-01', $time1),date('Y-m-t', $time1));
}
}
$months[] = array(date('Y-m-01', $time2),date('Y-m-d', $time2));
return $months;
}
