php - 为什么我在远程服务器上运行 Zend Framework 2 应用程序时收到错误 : table doesn't exist,？

Question

我创建了一个 RESTful zend2 应用程序，它在我的本地主机上运行良好。现在我想将它部署到远程服务器上，但出现了一些与 Adabter 相关的错误。我是 zend 框架的新手，我不确定为什么会出现任何错误，因为我仔细检查了每件事都是正确的。我在网上搜索了这个错误，但找不到任何与 Zend2 相关的有用答案。

我导出了整个本地主机数据库并将其导入到远程数据库，并将 local.php 和 global.php 中的所有数据库凭据更改为新主机中的新数据库。现在，当我想访问应用程序的数据库部分时，在模块中(比如 myApp/user 它应该以 json 格式给我数据库中的用户列表)，它给了我以下错误(我很抱歉如果我给出很多错误消息。我只想详细说明我的问题):

您真的确定所有配置都正确吗？ :)

如果是，那么可能是你换了一个不区分大小写的系统到一个区分大小写的系统。也许您可以进入您的数据库(使用 phpmyadmin 或类似工具来检查表是否存在以及名称是否对应)。或者尝试将所有表重命名为小字符(小写)。

为避免在移动/复制/迁移时出现问题，无论如何建议只为表和列使用小写名称。因此，不要像您那样使用驼峰式大小写，而是使用下划线。

因此尝试将名称更改为 my_app_database(表)和 user(列)，然后测试它是否有效。
