if you have Zend AMF setup and would like to get back a typed object you need to register it in Flash..
registerClassAlias("myAs3Obj", myAs3Obj);
first arg is the name of the object from php, second is the as3 object Flash will try to map it to. so long as the vars inside match up it should work fine.
for details on setting up Zend AMF (except for the above.. only seems to cover Flex) check out this..
