PHP：在发布多部分/表单数据时将字符串解析为数组

在FirefoxHTTP headers插件中，我记录了标题和帖子内容

标题如下

文章内容如下

我变成了下面的卷曲

但是当我发现http头时，它只发送text/html

我检查了php.net，它说如果值是数组，那么Content-Type头将设置为multipart/formdata

---

现在如何将$fields转换为数组？因此，数据将以多部分/表单数据格式发送。

这里有吗？请帮帮我，我绞尽脑汁了两天：这不是一个完整的答案，但你永远不需要自己构建这样的MIME边界。相反，您应该寻找一个接受键值对并为您生成所有这些的函数。
