New Comment:
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.

Here's a reasonably close substitute (run result through abs() if you don't
want potentially negative numbers):
// $dt1 and $dt2 can be any valid date string that DateTime accepts
// the time zone shouldn't affect anything (since $dt1 and $dt2 use same zone),
// but you can override the default
function daysdiff($dt1, $dt2, $timeZone = 'America/Chicago') {
$tZone = new DateTimeZone($timeZone);
$dt1 = new DateTime($dt1, $tZone);
$dt2 = new DateTime($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');
$diff = intval($y1 * 365.2425 + $z1) - intval($y2 * 365.2425 + $z2);
return $diff;
}

Nothing changed so yes, use VC9 builds instead for now.
