获取今日订单总数和订单总金额

 //fields区分出order_type不等于1的订单，订单金额money加运费order_freight合计
 $fields = [
     'count(1) as order_num',
     'sum(if(order_type != 1, money + order_freight, 0)) as order_price'
 ];
 //where区分统计今日订单，已付款pay_status状态
 $where = [
     [
         'create_time',
         'between',
         strtotime(date('y-m-d')).','.strtotime(date('y-m-d 23:59:59')),
     ],
     [
         'pay_status','=',1,
     ]
 ];
 $static = $this->field($field)->where($where)->where('is_deleted', 0)->find();
 return $static ? $static->toarray() : [];
