=item Patch from Kostas Chatzikokolakis handling encoding and sending null value.

=head2 Sun May 11 16:43:05 EDT 2003

=item Changed writeData to set type to "NULL" when the incoming data is undef. Previously
it became a String, just like other scalars.

=item Changed PHP's writeRecordset to a generic writeAMFObject. Verified Recordset support.

=head2 Sun Mar  9 18:20:16 EST 2003

=item Function writeObject should return the same as writeHash. This assumes that all meaningful data
are stored as hash keys.
