How to upload files (multipart/form-data) with multidimensional POSTFIELDS using PHP and CURL?

Question

I\'m having problems with posting a multidimensional array with file uploads using PHP and CURL.

The multidimensional array is for example:

$post[\'q

multipart/form-data doesn't support nested values. And I don't believe CURL can do it either.

I suspect the receiving end of your request is also a PHP script. If, then you can submit a nested array as one of the values, if you just prepare it yourself:

 $post['answers[0]'] = "yes";
 $post['answers[1]'] = "no";
 $post['answers[2]'] = "maybe";

Theoretically you'd just need 'answers[]' without the index, but that would overwrite the preceeding value - and thus only works with http_build_query.

I'm not sure if there is any HTTP library in PHP which can do this automatically.
