[pear::soap - wsdl] Dispatch map for returning arrays (newbie)

Hi, This is a very simple question. Let's say i want to creat a function (say testDB) that returns arrays (i.e. 0 => zero, 1 => one, 2 => two, etc...) of unkown variable size. What should my dispatch map look like ? PHP:____________________________________________________ $this->__dispatch_map['testDB'] = array('in' => array('inputStringSimple' => 'string'), 'out' => array(' ???? => ???? '), ); ________________________________________________________ Shane's talks example is OK for a fixed size array, i would like the same for any size array. As you may have guessed, i'm dealing with database query results which's size is unkhown. This question has already been asked here by someone else but nobody answerd, hopefuly i'll get some very needed help :) Luis ps: if someone can at least point me to some dispatch map examples it would be great.
