Date Difference in php on days? [duplicate]

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?

Answer 1

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
