You're working *WAY* too hard :-) function getDates($from, $to){ # Change the 1's to 0's to turn off debugging output: if (1){ echo "Computing Dates Between '$from' and '$to'<BR>\n"; } $year = substr($from, 0, 4); $month = substr($from, 5, 2); $day = substr($from, 8, 2); $start = mktime(0, 0, 0, $month, $day, $year); $year = substr($to, 0, 4); $month = substr($to, 5, 2); $day = substr($to, 8, 2); $end = mktime(0, 0, 0, $month, $day, $year); # Change this to <= to get the $end date included: while ($start < $end){ $datearray[] = date('Y-m-d', $start); if (1){ echo $datearray[count($datearray)-1], "<BR>\n"; } $day++; # Let PHP worry about wrapping days and months and leap years $start = mktime(0, 0, 0, $month, $day, $year); } return $datearray; ?> > /* Accessory function to getDates above. */ > > function zeroPadDate($year, $month, $day) { > if ($month<10) $mstr="0$month"; > if ($day<10) $dstr="0$day"; > return "$year-$mstr-$dstr"; > } You don't need this function. :-) > What could it possibly be due to?
