我的需求是把这个数组存到数据库里
但是现在，我得不到每一个键值对应的值。
还请大侠指点一下。
我上面写的得值方法是错的，你们看看我该怎样改一下。item下面是一个多维数组，因论坛只能发这点字符，所以剪了

Answer 2

还请指点一下吧，急啊
是这样的，我这个是解析的XML用的网上的一个函数  
就解成这个样子
XML结构是这样的。
http://interface.hd.sohu.com/360/variety.xml还请指点一下，怎么构造。

Answer 3

我现在是解决了，
但是我知道，这个XML遍历出来的数组结构不好
我很想知道，你们有没有好方法遍历数组没
我好学习学习，下一次就可以用上。

Answer 4

前题是遍历的话 那么就是for 和foreach了...
