答
Zend_Gdata_Calendar_EventEntry has method getWho(), which returns array of "whos". But in Zend_Gdata_Extension_Who I don't see method, which returns defined namespaces.
But you can access that property using Reflection - Example #2.
答
1) Show Zend_Gdata_Calendar_EventEntry class
2) Possibly in foreach loop or the class may have some method like as_array() to convert an object into array.
