yii遍历行下的每列数据(小1月考)

效果图：

控制器(1种)：

    //显示列表
    public function actionList()
    {
        //实例化对象
        $model= new Qiu();
        $country = \Yii::$app->db;
        //查询数据
        $data = $country->createCommand("select * from qiu join region on qiu.region_id=region.region_id")->queryAll();
        $region_ids = $country->createCommand("select region_id from region")->queryAll();
        $region = $country->createCommand("select * from region")->queryAll();
        //遍历数组
        $ids = array();
        $names = array();
        $count = array();
        //遍历区域ID
        foreach ($region_ids as $key => $v)
        {
            $ids[$key] = $v['region_id'];
        }
        //print_r($ids);die;
        //遍历球队
        foreach ($ids as $key => $val)
        {
            $data =Qiu::find()->where(['region_id'=>$val])->asArray()->all();
            $count[]=count($data);
            $rows[$val] = $data;
        }
        //print_r($rows);die;
        //根据所有记录进行遍历,显示最多行数
        $ji =  max($count);
        $arr = array();
        //找出对应的球队
        for($i=0;$i<$ji;$i++)
        {
            foreach($rows as $key => $val)
            {
                if(isset($val[$i]))
                {
                    $arr[$i][$key] = $val[$i]['q_name'];
                }
                else
                {
                    $arr[$i][$key] = '';
                }
            }
        }
        //var_dump($arr);die;
        //分配数据
        return $this->render('list',['arr'=>$arr,'region'=>$region]);
    }

(2种)：
 
    public function actionList1()
   {
        //实例化模型层
        $region = new Region;
        $qiu = new Qiu;
        //取出区域表的iQiud和所有数据,队表数据
        $region_ids = $region->find()->select('region_id')->column();
        $areas = $region->find()->asArray()->all();
        $team = $qiu->find()->asArray()->all();
        
        $count = array();
        $info = array();
        foreach ($region_ids as $aid) {//1,2,3--6
            foreach ($team as $key=>$val) {
                if($val['region_id'] == $aid){
                    $info[$aid][] = $val;
                    $count[]=count($info[$aid]);
                }                
            }
        }
        //var_dump($count);die;    
        $con = max($count);
        $arr = array();
        for ($i=0; $i <$con ; $i++) {
            foreach ($info as $key => $val) {
                if(isset($val[$i])){
                    $arr[$i][$key] = $val[$i]['q_name'];
                } else {
                    $arr[$i][$key] = '';
                }
            }
        }
        //var_dump($arr);die;
       return $this->render('list',['arr'=>$arr,'region'=>$areas]);
    }

视图层：

         <table border="1">
         <!--一行区域-->
         <tr style="background:red;">
         <?php foreach ($region as $key => $v1) {?>
         <td><?php echo $v1['region_name']; ?></td>
         <?php }?>
         </tr>

         <!--每列球队-->
         <?php foreach ($arr as $key => $val) {?>
         <tr>    
         <?php foreach ($val as $key => $v) {?>
         <td><?php echo $v; ?></td>
         <?php } ?>
         </tr>    
         <?php } ?>
         </table>
