有关andwhere绑参数的问题，请高人点[2.0]

$query_ol = Orderlist::find()->where([

                                'status' => Orderlist::STATUS_ACTIVE,
                                'phone' => \Yii::$app->user->identity->username,
                                ]);
    $query_ol->andWhere(['<', 'addtime', time()]);
    $query_ol->andWhere(['>=', 'addtime', ':addtime1']); 
    if($query_ol->andWhere([':addtime1'=>strtotime("-1 month")])->count()>=4){
           echo 'hello';
    }

报错提示如下：
Database Exception – yii\db\Exception

SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens
The SQL being executed was: SELECT COUNT(*) FROM so_orderlist WHERE (((status=’1′) AND (phone=’18663697137′)) AND (addtime < 1493111483)) AND (addtime >= ‘:addtime1’)
Error Info: Array
(

[0] => HY093
[1] => 0

)

你打印过最后执行的sql吗 看看是否你那个占位符到底是否好用了
多加一句，我记得andwhere是可以加params, 可以用下面2种方法，简化一行代码。
$query_ol->andWhere(‘addtime>=:addtime1’, [‘:addtime1’=>strtotime(“-1 month”)]);
$query_ol->andWhere([‘>=’, ‘addtime’, strtotime(“-1 month”)]);
