Yii单表常用语句

 通过GET方式获取网页&id的数值
//        $request = \yii::$app->request;
//        $id=$request->get(‘id‘);
//        dd($id);
//        $data = [
//            ‘userName‘ => "wqpeixun.com",
//            ‘ip‘ => 1270101,
//            ‘arr‘ =>[
//                ‘age‘ => 1,
//                ‘class‘ => ‘1班‘
//            ],
////        ];
//        $user = [
//            ‘userName‘ => ‘小兵老师‘,
//            ‘age‘ => 28,
//        ];
//        $article = [
//            ‘title‘ => ‘phpstorm真好用呀！‘,
//        ];
//        $data=[
//            ‘user‘=>$user,
//            ‘article‘=>$article,
//        ];
////        $data = compact(‘user‘, ‘article‘);
//        $data = [
//            ‘str‘ => ‘wew<script>alert (11);</script>‘,
//        ];

//        通过原生SQL语句获取数据
//        $request=\yii::$app->request;
//        $id=$request->get(‘id‘);
//        $sql = "select * from article where id=:id";

//        ];
//        $row = article::findBySql($sql,$data)->all();
//        dd($row);
