Everyone please read the full thread before complaining, it's a bug affecting VC6 builds only.
If you are affected just get VC9 builds from http://windows.php.net/download/ - you will also most
likely need a VC9 or VC10 build of Apache from http://www.apachelounge.com/download/
VC6 is very old, outdated and not supported anymore, it's easy enough and free to upgrade to
newer builds.

Still have this bug on the 5.3.5 version more than 2 years later.
It is not acceptable to have a "won't fix" decision on a major bug like this that is
affecting so many people.
Thank you in advance,

Your function can be changed to accept Datetime Objects for Strings this way. Also now calculates
datetime difference from dt1 to dt2 rather then the other way around.
private function daysdiff($dt1, $dt2, $timeZone = 'America/Chicago')
{
$tZone = new DateTimeZone($timeZone);
if(is_string($dt1))
{
$dt1 = new DateTime($dt1, $tZone);
}
if(is_string($dt2))
{
$dt2 = new DateTime($dt2, $tZone);
}
// use the DateTime datediff function IF we have a non-buggy version
// there is a bug in many Windows implementations that diff() always returns 6015
if( $dt1->diff($dt1)->format("%a") != 6015 ) {
return $dt1->diff($dt2)->format("%a");
}
// else let's use our own method
$y1 = $dt1->format('Y');
$y2 = $dt2->format('Y');
$z1 = $dt1->format('z');
$z2 = $dt2->format('z');
$diff = intval($y2 * 365.2425 + $z2) - intval($y1 * 365.2425 + $z1);
return $diff;
}

Also have this problem. A full year since last modified. No fixes yet?
I agree with the other use who said there should be more documentation on this error. I am sure lots
of us spent lots of time before we found this thread trying to figure out why diff() does not output
the correct result.
Right here would be a great place to put some documentation on the 6015 error: http://us3.php.net/manual/en/datetime.diff.php

The fix submitted by fbastage@yahoo.com on 2011-10-16 16:13 UTC solved the problem
for me on Windows 7 running WAMP on localhost and php 5.3.0

I am surprised that the number of days between two dates problem is not made clear right up front in
the documentation. It took me 3 hours to find this page and I was trying all different things to
make it work. I suspected a problem when the three different sets of dates I was using all came out
with the same answer, but when I finally used %a and they all came out with 6015, I knew, finally,
that there is a problem. The fact of the problem should be made very clear right up front.
