Question

I have array like below,

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
        )

)

if I unset the index[1] value from [14289] this one. after that the array display like below,

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
        )

)

But I need [14289] values like below,

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

the key value should be [1] not [2]. how can I do this?
