$shopObj = new ShopModel(); $this->data = $shopObj->field('id')->select(); //二维数组降一维 $this->data = $this->translatArray2($this->data); //一维数组打算顺序 shuffle($this->data); //长度4分割数组 $this->data = array_chunk($this->data,4); //查出随机的店铺 $this->data = $shopObj->alias('a')->field($this->Lfield) ->join('wd_yylm_shop_attr b','a.id = b.shopid','left') ->where('a.id','in',$this->data[$p-1]) ->select();//查出的二维数组下标是分页P,用In方法查出4个数据 if (empty($this->data)) { $this->msg = '数据为空'; }
shuffle(),将一维数组打乱顺序,成功返回1,失败返回0;
array_chunk($arr,$num),可以将一维数组$arr长度4个为一组,分割成若干个小数组
