I am having an array like this..

我有一个这样的数组。

 Array
    (
        [a] => 100%
        [b] => 0%
        [c] => 0%
        [d] => 0%
    )

I want to change this as

我想把这个换成

Array
(
    [0] => a,100%
    [1] => b,0%
    [2] => c,0%
    [3] => d,0%
)

Is it possible in php?

If you want to get keys of this array you can use array_keys() function
