我有这个模块web应用程序，它是zend框架1.12到doctrine 2（我只需要这样），现在我正试图从我的数据库中获取数据并在我点击时回显json_encode正确的url是url / api / people（将返回所有人）。
由于某种原因，我有这个错误告诉我t0._firstName作为一列，但我知道它根本不是一个列。我在控制器中使用_firstName作为变量。

答案 0 :(得分：2)
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
];
您无法直接获取属性，因为受保护，您必须使用以下实现的方法：
'firstname' => $obj->getFirstname(),
