Maybe because of DST? I don't really want to try and figure out
exactly why this code doesn't work, so instead let me suggest
something a bit simpler that does what you're trying to do:
$startDate = strtotime('2007-11-01');
$endDate = strtotime('+7 days', $startDate);
for($i = $startDate; $i < $endDate; $i = strtotime('+1 day', $i))
echo date('l Y-m-d', $i) . '<br/>';
