How to count days between 2 dates in php

March 11, 2013

A simple solution to count days between 2 dates is using DateTime method since php 5.3

function getDaysBetweenDates($from,$to,$addLastDay = false){
	$d1 = new \DateTime($from);
	$d2 = new \DateTime($to);
		$d2->add(new \DateInterval('P1D'));
	return $d1 -> diff($d2)->days;
echo getDaysBetweenDates('2013-03-01','2013-03-11');
echo getDaysBetweenDates('2013-03-01','2013-03-11',true);

If you need to count the last day too , just pass third parameter – true.

    Hello Ivan,
    When we find difference between these days ‘2013-03-01′,’2013-03-11’ without last day, i think the results may be 9 starts from 2nd day to 10th day(in this example)(I am not sure about that sir Please Help me)

    How does the DateInterval() works?

    Hello Kumar,
    if you are counting future dates you need the first day too. So the function is counting right. DateInterval is used as an representation of time. If you want to add 10 days to date time you use new \DateInterval(‘P10D’). See more on
