Change an object array into multidimensional array and print - php

Question

I have a multidimensional array. I am retrieving this from UPS RateInTransit API. I am receiving this in an object. Then i convert it into a simple array.
i have received the data into json from UPS. So i converted it into php array by Json_encode and json_decode.
After that from Object array to simple array, so i found this.
object(Ups\Entity\RateResponse)#81 (1) {
["RatedShipment"]=>
array(1) {
[0]=>
object(Ups\Entity\RatedShipment)#82 (12) {
["Service"]=>
object(Ups\Entity\Service)#83 (3) {
["Description"]=>
NULL
["code":"Ups\Entity\Service":private]=>
string(2) "03"
["description":"Ups\Entity\Service":private]=>
NULL
}
["RateShipmentWarning"]=>
string(56) "Your invoice may vary from the displayed reference rates"
["BillingWeight"]=>
object(Ups\Entity\BillingWeight)#89 (2) {
["UnitOfMeasurement"]=>
object(Ups\Entity\UnitOfMeasurement)#91 (4) {

["Description"]=>
NULL
["code":"Ups\Entity\UnitOfMeasurement":private]=>
string(3) "LBS"

}

}

string(3) "USD"
["MonetaryValue"]=>
float(0)
["Code"]=>
NULL
["Description"]=>
NULL

}

NULL
}
}
}
["SurCharges"]=>
array(0) {
}
["TimeInTransit"]=>
NULL
["NegotiatedRates"]=>
NULL
}
}
}
But i am unable to access ['RatedShipment]['BillingWeight']['Weight'].
Where did i write a wrong code???

Answer 1

What do you think to use $arr = (array) $obj;?
Because it still looks like an object.
Or you could access $obj->RatedShipment->BillingWeight->Weight?
