Update cURL.php

[andreipetcu]

Allow multipart/form-data on POST

[rmccue]

I'm not sure what your intention is here, but this will break existing functionality.

It will allow the use of CurlFile library or to send files via $data['file'] = '@/path/to/file' with multipart/form-data header instead of application/x-www-form-urlencoded.
Basically the library won't permit file upload because of that code line:
$data = http_build_query($data, null, '&');

It should let cURL handle how to send the data instead of forcing it to send with application/x-www-form-urlencoded header.

I've used the library with that line commented out and works. Why do you say it will break existing functionality?

[rmccue]

CurlFile or @/file support needs to be supported across both cURL and sockets consistently. Changing this will on the surface allow you to send files, but won't work for sockets, so this will break on any servers without cURL.

In addition, passing an array or object directly to cURL rather than handling it ourselves doesn't have the same behaviour; IIRC, there are subtle problems with different versions of cURL here.
