Let me first start with stating this:

This is indeed possible to do using curl. It is possible to do using the plain
libcurl interface, and it is even possible to do with the curl command line
tool. I am however not sure if this is possible to do using the PHP/CURL
interface, but then again I'm not an expert on those parts.

So this is a multipart formpost.

This doesn't look right. When you POST with curl, you *only* POST. Adding this
file here doesn't make any difference, as that won't be used when you POST.

That looks like the correct way.

That is not the right way. You want a multipart formpost, and such a post
doesn't look like that.

Try the command line tool and its -F option.
