HOW TO SUBTRACT YYYY-MM-DD FROM YYYY-MM-DD

[dlebowski]

I have found a couple of functions that do different formats.  I need it for this format.  I need to find out how many days difference there is between two dates.  Thanks in advance for the help!

assuming the dates are always valid, clever use of the strtotime function would work

$date1 = "2010-01-01";
$date2 = "2010-01-25";
$time1 = strtotime($date1);
$time2 = strtotime($date2);
$diff = abs($time2-$time1);
//convert seconds to days
$diff /= 60 * 60 * 24;//60 secs a min / 60 mins an hour / 24 hours a day
echo ceil($diff);

 

output:

24

Thank you!  I think that will work!
