Accessing StdClass value with colon :protected

Question

How do I access the value of stdClass with colon \":protected\"?

For example, I had this $obj with these result :

object(Google_Service_Plus_PeopleFeed)         


        

Answer 1

Well, I can finally access it with :

$kind = $obj['data']['items'][0]['kinds'];

Anybody can explain why? Just curious why it needs to be protected >.<
