While the DATEDIFF() is very useful in queries this will not help you unless both fields are in the table. Try this example $dteStartDate[$intCnt] = new DateTime($row[10]); $dteEndDate[$intCnt] =new DateTime($row[11]); $interval = $dteStartDate[$intCnt]->diff($dteEndDate[$intCnt]); echo $interval->format('%R%a days'); -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
