我试图在一个api上导入数据到mysql数据库。我让它在小范围内工作。
我现在修改了它，使它更符合当前的数据库。它是一个很大的表，而且结构很差，但是为了简单和维护，我尝试保持mysql数据库和应用程序数据库内联。msql=windows-based application:mysql=server数据库，从本地托管的msql中提取数据，并将其导入外部托管的mysql数据库。
由于我已经扩展了代码，它不再工作，这可能是一些因素，如表需要结构化/索引/主，或者我通过查询传递了太多的数据。应用程序开始看起来很混乱。
问题是，是否有必要和更好地实践我列出每一列并匹配数据集，以尝试利用 MySQL INFORMATION_SCHEMA 改为列出列。
这是到目前为止的代码，我已经删除了一些列。
我们有一个服务器和主机：

}

调用函数：handler `test_api.php` //它确实包含了一个用于api.php的include

if($_GET["action"] == 'insert')
{
$data = $api_object->insert();
}

这不会是最后一件事，因为我将从msql中提取构建数组并以这种方式发布，这只是为了测试而这样布置的
