php - 如何获取 php 键作为 php 数组中的值

Question

我有一个像这样的数组..

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

我想将其更改为

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

php 可以吗？

Answer 1

一个简单的foreach就可以了..

foreach($arr as $k=>$v)
{
    $new_arr[]=$k.",".$v;
}
