concatenate variable json.data

good there is some way to concatenate a json, what my json returns is not more than a select but there are 120 records go from r1 ........ r120, I want to go through it but in the console it prints me undefined1 .... undefined120, and what I want is for me to return what I have, not to be copying and pasting 120 times

for(var i=1; i<111;i++){
            console.log(json.Data.r+[i]);
            }

This is my controller, if it's any good

if ($data) {

                        $this->output
                        ->set_content_type('application/json')
                        ->set_status_header(200)
                        ->set_output(json_encode(array(
                            "Status" => true,
                            "Message" => "GET",
                            "Data" =>  $data
                        )));
                    }else
                    {
                         $this->output
                        ->set_content_type('application/json')
                        ->set_status_header(500)
                        ->set_output(json_encode(array(
                            "Status" => false,
                            "Message" => "GET"

                        )));
                    }
