Yii遍歷行下每列資料的方法

本文實例講述了Yii遍歷行下每列資料的方法。分享給大家參考，如下：

效果圖如下：

控制器(1種)：

//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][&#39;q_name&#39;];
        }
        else
        {
          $arr[$i][$key] = &#39;&#39;;
        }
      }
    }
    //var_dump($arr);die;
    //分配数据
    return $this->render(&#39;list&#39;,[&#39;arr&#39;=>$arr,&#39;region&#39;=>$region]);
}

(2種)：

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][&#39;q_name&#39;];
        } else {
          $arr[$i][$key] = &#39;&#39;;
        }
      }
    }
    //var_dump($arr);die;
    return $this->render(&#39;list&#39;,[&#39;arr&#39;=>$arr,&#39;region&#39;=>$areas]);
}

reee大家基於Yii框架的PHP程式設計有幫助。
