How to access a key in a stdclass
===

I have this situation:


    object(stdClass)#203 (1) {
      ["1"]=>
      object(stdClass)#212 (7) {
        ["user_id"]=>
        int(1)
        ["type"]=>
        string(6) "Device"
        ["name_first"]=>
        string(0) ""
        ["name_last"]=>
        string(0) ""
        ["name_display"]=>
        string(0) ""
        ["gender"]=>
        string(11) "Unspecified"
        ["birthday"]=>
        string(0) ""
      }
    }

I want to access either "user_id" or the ["1"], but this is of type stdclass so I can't treat it like an array. (Note: this is from `json_decode`)
