第一个值作为PHP数组2中的关键答案

I have an array like below;

我有一个像下面的数组;

Array
(
    [0] => Array
        (
            [id] => 20
            [contract_id] => 71
            [service_type_id] => 184
            [duration] => 33
            [isUnlimited] => 0
        )

    [1] => Array
        (
            [id] => 21
            [contract_id] => 71
            [service_type_id] => 182
            [duration] => 33
            [isUnlimited] => 0
        )

    [2] => Array
        (
            [id] => 22
            [contract_id] => 71
            [service_type_id] => 183
            [duration] => 33
            [isUnlimited] => 0
        )

)

Could you please help me to replace ['service_type_id'] value with its own index? Output will be as follows;

你能帮我用自己的索引替换['service_type_id']值吗?产量如下;

[184] => Array
    (
        [id] => 20
        [contract_id] => 71
        [service_type_id] => 184
        [duration] => 33
        [isUnlimited] => 0
    )

I know, it is somewhere in *, I have seen it several months ago, but now I really really couldn't find it. If someone remembers and edit this question, I will for sure remove it, no problem.

我知道,它在*中的某个地方,几个月前我已经看过了,但现在我真的找不到它。如果有人记得并编辑了这个问题,我肯定会删除它,没问题。

Thanks in advance

You can use array_column()(http://php.net/manual/en/function.array-column.php) to do this...

您可以使用array_column()(http://php.net/manual/en/function.array-column.php)来执行此操作...

$arr = array_column ( $arr, null, 'service_type_id');

This creates a new array using service_type_id as the new index.

这将使用service_type_id作为新索引创建一个新数组。
