示例：

<?xml version="1.0"?>

<root>

<User>

<UserGUID>123456</UserGUID>

<NickName>aaa@163.com</NickName>

</User>

</root>

转换成数组后的形式是：

Array

(

    [root] => Array

        (

            [User] => Array

                (

                    [UserGUID] => 123456

                    [NickName] => aaa@163.com

                )

        )

)
