PHP PDO试图获取非对象的属性

Question

我在尝试

时获得Notice: Trying to get property of non-object in

foreach ($query->fetch(PDO::FETCH_OBJ) as $row) {
        echo $row->id_users;
        echo $row->username;
        echo $row->password;
        echo $row->email;
    }

当我使用print_r($query->fetch(PDO::FETCH_OBJ))时，我正在

Class Object ( [id_users] => 1 [username] => test [password] => test [email] => test )

Answer 1

通常，为了遍历记录集，你可以沿着这些方向做点什么。

while( $row = $query->fetch(PDO::FETCH_OBJ) ){
        echo $row->id_users;
        echo $row->username;
        echo $row->password;
        echo $row->email;
}
