I have this math equation this list helped me generate a few weeks ago.
The purpose is to calculate how many days have passed between 2 dates.
Right now my output ($difference) is 93.9583333333 days.
I am finding this a little weird. Does anyone see anything wrong with
the way this is calculated:
$date1 = strtotime($date1); (March 21st 2008)
$date2 = strtotime($date2); (December 18th 2007)
echo $date1 => 1206072000
echo $date2 => 1197954000
#86400 is 60 seconds x 60 minutes x 24 hours (in other words 1 days
worth of seconds)
$factor = 86400;
$difference = (($date1 - $date2) / $factor);
As Casey suggested, it is a timestamp issue.
