PHP cURL提交POST数据，多部分/表单数据混乱

Question

所以我有一个网站，我正在建设，它将使用数据库中的数据来填写不同网站上的表格。现在我明白了，这可以很容易地用cURL或python来完成，但是，当我截取和读取post数据时，通常会非常混乱。例如，在此表单中，只有注释和分级选项，但包含所有类型的其他垃圾:

我以前处理过这些类型的表格。他们是一个痛苦。我所做的是：

1. 卷曲页面，没有文章数据或任何内容
2. 解析HTML以获取表单元素及其当前值
3. 更改需要设置的字段的值
4. 将所有内容格式化为一个数组以供发布
5. 用该帖子数据再次卷曲页面。

哦，有时需要将像__EventType这样的字段设置为所需事件的特定字符串。为了帮助分解第二个卷曲应该是什么样子，使用Chrome开发人员工具查看解析好的请求。你甚至可以把它复制成卷曲。
