Date Difference in php on days?


Question

Is there a quick way to calculate date difference in php? For example:

$date1 = '2009-11-12 12:09:08';
$date2 = '2009-12-01 08:20:11';

And then do a calculation, $date2 minus $date1

I read php.net documentation, but no luck. Is there a quick way to do it?

Accepted Answer

strtotime will convert your date string to a unix time stamp. (seconds since the unix epoch.

$ts1 = strtotime($date1);
$ts2 = strtotime($date2);

$seconds_diff = $ts2 - $ts1;

I would recommend to use date->diff function, as in example below:

   $dStart = new DateTime('2012-07-26');
   $dEnd  = new DateTime('2012-08-26');
   $dDiff = $dStart->diff($dEnd);
   echo $dDiff->format('%r%a'); // use for point out relation: smaller/greater
