Php 将startDatetime和endDatetime与DB表进行比较'；s开始日期时间和结束日期时间

我正在为物业预订创建脚本。如果用户希望在2020-04-23 02:15:33至2020-04-23 04:15:33期间预订物业，并且在2020-04-23 01:01:33至2020-04-23 04:00:00期间已经有其他人预订，则必须是已预订的show property

    $user_start_date = $this->put('start_date');
    $user_end_date = $this->put('end_date');

    $allDates = new DatePeriod(
                new DateTime($user_start_date),
                new DateInterval('P1D'),
                new DateTime($user_end_date.' +1 day')
   );

   $reqDates = [];
    foreach ($allDates as $date) {
        $reqDates[] = $date->format('Y-m-d H:i:s');
    }

    $bookedDates = $this->db->select('start_date,end_date')
                       ->where('status',1)
                       ->where('property_id', $this->put('property_id'))
                       ->group_start()

                       ->get('property_bookings')->result();
    $flag = 1;

            $http_code = REST_Controller::HTTP_INTERNAL_SERVER_ERROR;
            $this->response($data, $http_code);
