I have attatched a patch to do recordset, datetime, and field tags processing
during deserialization.

Hi all:
I am thinking of a way to transform WDDX recordset element into PHP varialbles
when deserializing the packet.
It seems that all recordset will look like:
var name=querynamerecordset rowcount=? fieldname=f1,f2,...fnfield
name=f1.../field.../recordset/var
The above can be transformed into:
var name=querynamestringf1,f2,...fn/string/varvar
name=f1array.../array/varvar name=f2array.../array/var...
If we parse as this transformation, in PHP script:
$values = wddx_deserialize($packet);
$values[queryname] = f1,f2,...,fn;
$values[f1] = values in array for f1 field;
$values[fn] = values in array for fn field;
Should this solve the recordset problem?
Deserializing the recordset is not a problem, but creating one out of
PHP values is since there is no exact mapping. It would be better to
have it work both ways, but maybe deserialization only support at this
point is fine.
