数组PHP

Question

我对数组有问题。我要总结给定的数量（数量）。

我想得到：

blyszczaca Normal = 6;

czapkoszal正常= 6;

czapkoszal Luxury = 2;

etola狼= 1;

etola正常= 2;

此数组中的

。你能帮我吗？我考虑了最近4个小时，什么也没有。还在学习。

Array
(
    [0] => Array
        (
            [produkt] => blyszczaca
            [model] => Normal
            [price] => 27.00
            [qty] => 2
        )

    [1] => Array
        (
            [0] => blyszczaca
            [1] => Normal
            [2] => 27.00
            [3] => 2
        )

    [2] => Array
        (
            [0] => blyszczaca
            [1] => Normal
            [2] => 27.00
            [3] => 2
        )

    [3] => Array
        (
            [0] => czapkoszal
            [1] => Normal
            [2] => 41.00
            [3] => 2
        )

    [4] => Array
        (
            [0] => czapkoszal
            [1] => Luxury
            [2] => 45.00
            [3] => 2
        )


    [5] => Array
        (
            [0] => czapkoszal
            [1] => Normal
            [2] => 41.00
            [3] => 2
        )

    [6] => Array
        (
            [0] => czapkoszal

            [2] => 41.00
            [3] => 1
        )

    [7] => Array
        (
            [0] => czapkoszal
            [1] => Normal
            [2] => 41.00
            [3] => 1
        )

    [8] => Array
        (
            [0] => etola
            [1] => Wolf
            [2] => 47.00
            [3] => 1
        )

    [9] => Array
        (
            [0] => etola
            [1] => Normal
            [2] => 39.00
            [3] => 1
        )

    [10] => Array
        (

            [3] => 1
        )

谢谢。

Answer 1

您应该使用唯一的键创建新的数组并计算数量，例如：

$sums = [];
foreach ($your_array as $item) {
    // create a unique key as concatenation of `product` and `model`
    $key = $item['product'] . ':' . $item['model'];

    // check if such key exists, if not - init key with `0`
    if (!isset($sums[$key])) {
        $sums[$key] = 0;
    }

    // add current `qty` to the value of `$sums[$key]`
    $sums[$key] += $item['qty']
}

Answer 2

您可以在输出数组中基于produkt和model创建自定义键。然后，将qty添加到该键。请尝试以下操作：

// Create a array to store the sum
$sums = array();

// Loop over the input array 
foreach ($input as $value) {

    // create a custom key based on produkt and model
    $key = $value['produkt'] . ' ' . $value['model'];

    // initalize the key 
    $sums[$key] = $sums[$key] ?? 0;

    // add the quantity
    $sums[$key] += (int)$value['qty'];
}
