无法访问PHP的一些对象属性（RedBeanPhp对象）

Question

我的对象是var_dump。这是输出。在我的代码对象中是$ d-＆gt; depositType。当我回显$ d-＆gt; depositType-＆gt; id或$ d-＆gt; depositType-＆gt;年时，我得到了我想要的值。但是，当我尝试获取$ d-＆gt; depositType-＆gt; name或$ d-＆gt; depositType-＆gt; name时，我得到null。请有人帮帮我。谢谢。

    object(RedBean_OODBBean)[47]
      private 'flagSkipBeau' => boolean false
      private 'properties' => 
        array (size=4)

PHP对变量区分大小写：http://www.php.net/manual/en/language.variables.basics.php

$d->depositType->name不存在。

$d->depositType->Name。
