I have an array like the following . . . 

```
Array
(
    [code] => BILL
    [assets] => Array
        (
            [en] => Array
                (
                    [labels] => Array
                        (
                            [datestamp] => April 30, 2013
                        )

                    [data] => Array
                        (
                            [Equity] => 88.83000000000
                            [Global] => 10.84000000000
                            [Other] => 0.33099095766
                        )

                )

        )

)

```

I have run the array\_map function on this array to remove the `[en]` array 

```
$en = array_map(function ($e){ return $e['en']; } , $en );

```

note how the resulting array has truncated the value for `[code]` from `BILL` to `B`

```
Array
(
    [code] => B
    [assets] => Array
        (
            [labels] => Array
                (
                    [datestamp] => April 30, 2013
                )

            [data] => Array
                (
                    [Equity] => 88.83000000000
                    [Global] => 10.84000000000
                    [Other] => 0.33099095766
                )

        )

)

```

Any tips on how to avoid that from happening. It is removing the array with the key `[en]` as required, but I don't want the value for `[code]` to be truncated.

Thanks.
