交换二维数组的行和列 [英] Swap 2D array's rows and columns

问题描述

我需要将 CSV 文件中的列放入数组(多维数组或数组数组)中.我使用了 CSV.au3 加载 rows 就好了，但我需要 columns 在那个地方.我的 CSV 文件如下所示:

I need to get columns from a CSV file into an array (multidimensional array or array of arrays). I used CSV.au3 which loads the rows just fine, but I need the columns in that place. My CSV file looks like:

Item 1, Item 2, Another Item
Item 3, Item 4

它创建了一个多维数组，如下所示:

It creates a multidimensional array that looks like:

$aResult[0] = [0] => 'Item 1', [1] => 'Item 2', [2] => 'Another Item'
$aResult[1] = [0] => 'Item 3', [1] => 'Item 4'

我希望它看起来像什么:

Where I would like it to look like:

$aResult[0] = [0] => 'Item 1', [1] => 'Item 3'
$aResult[1] = [0] => 'Item 2', [1] => 'Item 4'
$aResult[2] = [0] => 'Another Item'

对于每一行，它应该包含列而不是行.

For each row it should contain the column not the row.

推荐答案

我从这个项目中休息了一段时间，最终自己解决了这个问题:

I had a break from this project for a while, and ended up figuring it out myself:

;Load the first line into an array (for our Count Later)
$columnsCounter = StringSplit($content[1], ",")
;Here we use the row count (from $content) and column count (from $columnsCounter)
;We define an array that is the perfect size for our Menu Items
Dim $MenuItems[$content[0] + 1][$columnsCounter[0] + 1]

; Now we loop through each row and column
For $x = 1 To ($content[0]) - 1
    ;Create an array with the row we are looking at
    $oneRow = StringSplit($content[$x], ",")
    ;now loop through each column
    For $y = 1 To ($columnsCounter[0])
        ;Grab the item we want and add it to our menu items array
        $MenuItems[$x][$y] = $oneRow[$y]
    Next
Next
