I have some array object value like this :
object(stdClass)#32 (1) { 
    ["0"]=> object(stdClass)#33 (2) { 
                ["plan_type"]=> string(5) "offer" 
                ["plan_id"]=> string(4) "7395"
            } 
}
I want to get the value of plan_type from that object. How could I do that without looping ?
