Answer 1

you've got at least one syntax error (_ in your curlopt_url line). Have you checked for curl errors after the exec() call?

$response = curl_exec($ch);
if ($response === false) {
   die(curl_error($ch));
}

as well, your comment indicates the file field's name is "file_box", but you're using just "file" as your upload field. You must match what scribd is expecting. You can't just throw a file over their way and expect it to work. You're using curl to recreate what a browser would do, which means you have to duplicate all the fields/data that gets sent when a normal browser-based upload is performed.
