如何将数组的第一个值转换为键，第二个值转换为值 [英] How to convert array first value as key and second value as value

问题描述

我正在做一些数组操作.

Hi I am working on some array operations.

我需要将数组的第一个值转换为键，并将数组的第二个值转换为值.

I need to convert first value of array as key and second value of array as value.

我有一个变量 $ testArray ，它存储如下所示的数组.

I have one variable $testArray which stores array like below.

 Array
(
    [0] => Array
        (
            [0] => Color
            [1] => White on Red
        )

    [1] => Array
        (
            [0] => Depicted Text
            [1] => EMPTY
        )

    [2] => Array
        (
            [0] => Depth [Nom]
            [1] => 0.004 in
        )

    [3] => Array
        (
            [0] => Language
            [1] => English
        )

    [4] => Array
        (
            [0] => Length [Nom]
            [1] => 10 in
        )

    [5] => Array
        (
            [0] => Material
            [1] => Adhesive Vinyl
        )

    [6] => Array
        (
            [0] => Mounting
            [1] => Surface
        )

    [7] => Array
        (
            [0] => Width [Nom]
            [1] => 14 in
        )

    [8] => Array
        (
            [0] => Wt.
            [1] => 0.056 lb
        )

)

预期输出:

    Array
(
    [0] => Array
        (
            [Color] => White on Red
        )

    [1] => Array
        (
            [Depicted Text] => EMPTY
        )

    [2] => Array
        (
            [Depth [Nom]] => 0.004 in
        )

    [3] => Array
        (
            [Language] => English
        )

    [4] => Array
        (
            [Length [Nom]] => 10 in
        )

    [5] => Array
        (
            [Material] => Adhesive Vinyl
        )

    [6] => Array
        (
            [Mounting] => Surface
        )

    [7] => Array
        (
            [Width [Nom]] => 14 in
        )

    [8] => Array
        (
            [Wt.] => 0.056 lb
        )

)

我已经尝试过使用数组函数array_keys和array_values，但无法正常工作

推荐答案

使用 array_map 函数:

$result = array_map(function($v){
    return [$v[0] => $v[1]];
}, $testArray);
