This method converts fields with the array notation
(like foo[bar] to arrays) like PHP does.
The returned array is consistent with the array for field values
(@see getPhpValues), rather than uploaded files found in $_FILES.
For a compound file field foo[bar] it will create foo[bar][name],
instead of foo[name][bar] which would be found in $_FILES.
