记录之前在第一次租房到离开时的住宿费

电表开始是:2385度，水表开始是:222方。电费是1元1度，水是3元1方。

数据是通过phpmyadmin,对着收据单一张一张输入进去的。数据借助Yii2查询，查询结果，1个数组存放每个日期的总金额，1个数组存放每个key下值。输出的json数据放入到demo中，替换数据。就可以了。使用composer命令安装了yii2的basic模板，项目名称是basic.

composercreate-project yiisoft/yii2-app-basic basic 2.0.11

basic/controllers/SiteController.php文件的actionIndex方法修改为:

    /**
     * Displays homepage.
     *
     * @return string
     */
    public function actionIndex()
    {
        $posts = Yii::$app->db->createCommand('SELECT * FROM `live` order by id')
            ->queryAll();

        $arrkey = array();
        $sum = array();
        foreach($posts as $value){
            $sum[] = $value['rent'] + $value['network'] + $value['water'] + $value['electric'];
            foreach($value as $key=>$row){
                if(array_key_exists($key,$arrkey)){
                    $data = $arrkey[$key];
                    array_push($data,$row);
                    $arrkey[$key] = $data;
                }else{
                    $arrkey[$key] = array($row);
                }
            }
            
        }

        //print_r($arrkey);
        return $this->render('index',['json'=>$arrkey,'sum'=>$sum]);
    }

在basic/views/site/index.php文件中，添加了

 <div class="row">
            <div class="col-lg-12">
            <?php foreach($json as $key=>$row):?>
                <p><?php echo $key.' : '.json_encode($row);?></p>
            <?php endforeach;?>
            <p>sum : <?php echo json_encode($sum);?></p>
            </div>
        </div>

输出的结果是:

其中双引号数据，通过sublime text3 替换方法，替换成没有双引号的数据了。
