[moka同学笔记]YII2.0 判断签约状态，sql的两种查询方法

方法一：

//判断签约状态
                                $signed = 0;
                                $sql="SELECT * from usho_community_sign_record WHERE com_id=$r->id AND
                                end_date = (SELECT MAX(end_date) AS Largest_End_date from usho_community_sign_record WHERE com_id=$r->id)";
                                $sign_model = Yii::$app->db->createCommand($sql)->queryAll();

                                if(!empty($sign_model)){
                                       foreach($sign_model as $s){
                                        $start_date = $s['start_date'];
                                        $end_date = $s['end_date'];
                                        $now_date = date("Y-m-d H:i:s",time());
                                        if($start_date >$now_date){
                                            $signed = 3;
                                        }
                                        if($start_date <$now_date && $end_date > $now_date){

                                    }
                                }

                                switch($signed){

                                        break;

                                        break;
