Question

I was wondering how I could go about accessing values within an object, such as ‘backpackPosition’? I’m guessing I would have to put it in some kind of foreach loop, but I have no idea how to get the values.

TF2Inventory Object
(
[fetchDate] => 1234541231
[items] => Array
(
    [60] => TF2Item Object
        (
            [equipped] => Array
                (
                    [scout] => 1
                    [sniper] => 1
                    [soldier] => 1
                    [demoman] => 1
                    [medic] => 1
                    [heavy] => 1
                    [pyro] => 1
                    [spy] => 1
                )

            [attributes] => Array
                (
                    [0] => stdClass Object
                        (
                            [name] => custom employee number
                            [class] => set_employee_number
                            [value] => 0
                        )

                    [1] => stdClass Object
