Answer #1:

To upload a file that's on your server, yes, curl can do the trick.

You'll want to use the CURLOPT_POSTFIELDS option, passing it to the curl_setopt function (quoting) :

The full data to post in a HTTP "POST" operation.
To post a file, prepend a filename with @ and use the full path.

Not tested, but I suppose that something like this should work :

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setpopt($ch, CURLOPT_POSTFIELDS, array(
        'file' => '@/..../some-file.txt',    // you'll need to adapt this
        // some other fields ?
$result = curl_exec($ch);
