这篇文章主要介绍了Yii遍历行下每列数据的方法,结合实例形式分析了Yii框架下数据遍历的相关操作技巧,需要的朋友可以参考下
本文实例讲述了Yii遍历行下每列数据的方法。分享给大家供大家参考，具体如下：
效果图如下：
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>
