【中文标题】消息：SQLSTATE [42S22]：未找到列：1054 “字段列表”中的未知列“t0._firstName”【英文标题】：Message: SQLSTATE[42S22]: Column not found: 1054 Unknown column 't0._firstName' in 'field list' 【发布时间】：2016-12-28 22:17:05 【问题描述】：我有这个模块 web 应用程序，它是 zend 框架 1.12 到学说 2（我只需要这样），现在我正在尝试从我的数据库中获取数据，并在我点击正确时回显 json_encode url 是 url/api/people （将返回所有人）。
出于某种原因，我遇到了这个错误，它告诉我 t0._firstName 作为一列，但我知道它根本不是一列。我确实在我的控制器中使用 _firstName 作为变量。

【问题讨论】：
t0.是教义为您的属性使用的内部名称，这不是错误。 您可以发布查询吗？ @hokusai，你好！我已经编辑了帖子并且已经这样做了。 @hokusai，你好，所以当我更深入地研究它时，我只是忘了把 () 放在 $peopleClass = new API\Entity\People; 之后我修复了它，现在它返回 4 个对象，这是正确的，但它们都是空的。我不知道为什么。 【参考方案1】：如果您使用它来获取对象的属性：
$resultArray[] =
[
'id' => $obj->id,
'firstname' => $obj->firstname,
'lastname' => $obj->lastname,
"food" => $obj->food
];
你不能直接获取你的属性，因为有保护，你必须使用你实现的方法，比如：
'firstname' => $obj->getFirstname(),
