我在print_r($_POST)时收到此数组，从下面的结果我想获得skin的值。

我该怎么办？

 Array
    (
        [form_key] => WceDMPJOQD17ZeSW
        [config_state] => Array
            (
                [themeoptions_general] => 1
            )

        [groups] => Array
            (
                [general] => Array
                    (
                        [fields] => Array
                            (
                                [themeoptions_images] => Array
                                    (
                                        [skin] => 1.jpg
                                    )

                                [themeoptions_customcss] => Array
                                    (
                                        [value] => color:#333;
                                    )

                            )
