If you need something like this in a pre 4.3 version, here is a rough hack I was working on before I realized I didn't need this after all.

       preg_match('/Fields\[(.*)\]/', $raw_pdf, $field_data);
       echo "Fields: ", htmlentities($field_data[1]), "<HR>\n";
       $field_data = $field_data[1];
       $key_value = explode(">><<", $field_data);
       $key_value[0] = substr($key_value[0], 2);
       $key_value[count($key_value) - 1] = substr($key_value[count($key_value) - 1], 0, -2);
       while (list(, $kv) = each($key_value)){
               list($key, $value) = explode("/V", $kv);
               $key = substr($key, 2);
               if ($key[0] == '('){
                       $key = substr($key, 1, -1);
               }
               if ($value[0] == '/'){
                       $value = substr($value, 1);
               }
               if ($value[0] == '('){
                       $value = substr($value, 1, -1);
               }
               echo "Key: $key Value: $value<BR>\n";
       }

The $raw_pdf can either be the $HTTP_RAW_POST_DATA before you write a submitted PDF, or it can just be the raw PDF data you would read from a PDF using, say:
$raw_pdf = implode("", file("/path/to/your/fdf/whatever.pdf"));

You'll probably need to tweak this to do something more interesting than just printing the stuff.

Hmmmm.  Think they'll throw me in jail for this post?  Oh well.
