如何在取消设置数组值后设置键值？

Question

我有如下的数组，

Array
(
    [14289] => Array
        (
            [0] => Karthikeyan
            [1] => Mathi
            [2] => RAvi
        )

    [14279] => Array
        (
            [0] => Karthikeyan
            [1] => Mathi
            [2] => RAvi
        )

    [14288] => Array
        (
            [0] => Karthikeyan
        )

    [14291] => Array
        (
            [0] => Mathi
        )

    [14284] => Array
        (
            [0] => RAvi
        )

)

如果我从[14289]这个取消设置索引[1]值。之后数组显示如下，

Array
(
    [14289] => Array
        (
            [0] => Karthikeyan
            [2] => RAvi
        )

    [14279] => Array
        (
            [0] => Karthikeyan
            [1] => Mathi
            [2] => RAvi
        )

    [14288] => Array
        (
            [0] => Karthikeyan
        )

    [14291] => Array
        (
            [0] => Mathi
        )

    [14284] => Array
        (
            [0] => RAvi
        )

)

但我需要[14289]值，如下所示，

Array
(
    [14289] => Array
        (
            [0] => Karthikeyan
            [1] => RAvi
        )
........

键值应为[1]而不是[2]。我怎么能这样做？

Answer 1

在阵列上使用array_values。

Answer 2

后

unset $example_array[14289][1];

DO

$example_array[14289]= array_values($example_array[14289]);
