Question

我有一个像这样的doctrine2查询：

$query = $this -> doctrine -> em -> createQuery ("SELECT a, b FROM ORM\Dynasties2\Maillinks a JOIN a.msgId b");

返回mixed results，类似于：

ORM\Dynasties2\Maillinks Object 
( 
    [id:ORM\Dynasties2\Millinks:private] => 1 
    [toUser:ORM\Dynasties2\Maillinks:private] => 16 
    [isRead:ORM\Dynasties2\Maillinks:private] => 0 
    [msgId:ORM\Dynasties2\Maillinks:private] => ORM\Dynasties2\Mailmsgs Object 
    ( 
        [id:ORM\Dynasties2\Mailmsgs:private] => 1 
        [msgText:ORM\Dynasties2\Mailmsgs:private] => asdfasdfasdfasdfasdfasdf 
        [fromUser:ORM\Dynasties2\Mailmsgs:private] => 13 
        [timeStamp:ORM\Dynasties2\Mailmsgs:private] => DateTime Object 
        (       
            [date] => 2012-04-20 12:17:29 
            [timezone_type] => 3 
            [timezone] => America/Los_Angeles 
        ) 
        [onTurn:ORM\Dynasties2\Mailmsgs:private] => 1 
        [importance:ORM\Dynasties2\Mailmsgs:private] => 2 
        [msgType:ORM\Dynasties2\Mailmsgs:private] => 1 
    ) 
)

我可以轻松地访问“顶部”的一些数据 echo $row -> getToUser();返回“16”

我尝试echo $row -> msgId-> getMsgText();，但返回Fatal error: Cannot access private property ORM\Dynasties2\Maillinks::$msgId

如何访问

中对象中的数据

或者：我的查询和结果是否已损坏？我是否需要对我的查询或实体做一些不同的事情？

这不适合你吗？

$row->getMsgId()->getMsgText();

您应该能够检查实际的实体文件（无论是否有构建它们的学说，或其他人做过）来检查该实体的getter和setter。

嵌套对象（来自DQL select的混合结果）
