这是示例数组

Array
(
    [note] => Array
        (
            [to] => Array
                (
                    [user] => Array
                        (
                            [name] => First User
                        )

                    [abc] => 123
                    [lmn] => 4582
                )

            [from] => Jani
            [heading] => Reminder
            [body] => Array
                (
                    [abc] => 123
                )

        )

)

我有一个像“note > to > abc”这样的字符串，并且想要“to”数组下的“abc”值。那么我怎样才能得到这个值呢？
