PHP>引用数组[0]

Question

How do I reference [0]?

object(GetClassSchedulesResult)#8 (6) { 
["ClassSchedules"]=> object(stdClass)#9 (1) { 
["ClassSchedule"]=> array(20) { 
[0]=> object(ClassSchedule)#10 (21) { 
["Classes"]=> string(18) "Rails" 

This works:

$classes = $service->GetClassSchedules($parameters)->
             GetClassSchedulesResult->ClassSchedules->ClassSchedule;

I'm trying to get to "Classes". I'm having trouble referencing the [0]: This does not work:

$classes = $service->GetClassSchedules($parameters)->
             GetClassSchedulesResult->ClassSchedules->ClassSchedule->0->Classes;

UPDATE: Once I reference it correctly, the output always includes something like:

string(18) "the data i want here" ?>

Any easy way to get the data without string(18) and ?>?

This should work:

$classes = $service->GetClassSchedules($parameters)->
   GetClassSchedulesResult->ClassSchedules->ClassSchedule[0]->Classes;
