我正在一个网站上工作,我们需要删除类型为整数的数组的索引.
你有任何想法或建议吗？
我的数组看起来像这样：

Array
(
    [0] => first
    [first] => second
    [1] => second
    [second] => second
    [2] => third
    [third] => third
    [3] => forth
    [forth] => v
    [4] => fifth
    [fifth] => fifth
)

我们如何从数组中删除整数索引.更多的事情要注意我们没有静态数组我们不知道有多少索引.

需要这样的：

Array
(  
    [first] => second  
    [second] => second  
    [third] => third  
    [forth] => v
    [fifth] => fifth
)
