Question

我需要帮助组织我的库存数组。该结构是一个大型库存数组，其中包含一系列项目。每个项目数组包含以下内容： item，item_group，item_no和已售出的数组。出售包括日期和数量的内部数组。现在，我无法为我需要的输出组织它。我会给你们一些输入和输出的样本。所以请检查，非常感谢。

我的$ inventory数组的样本部分

从那里，我想要展示的是这样的。按日期升序分组。并且每个项目=＆gt;已售出数量

Array
(
[0] => Array
    (
        [date] => 2017-10-28
        [NK] => 11
        [FL] => 7
        [AD] => 5
        [CV] => 4
        [NB] => 12
        [SP] => 4
        [WB] => 5
        [wny] => 4
        [bs] => 15
    )
[1] => Array
    (
        [date] => 2017-10-29
        [NK] => 1
        [FL] => 2
        [AD] => 3
        [CV] => 6
        [NB] => 4
        [SP] => 6
        [WB] => 2
        [wny] => 6
        [bs] => 2
        [st] => 16
        [ayhtdws] => 2
        [sif] => 3
        [bb] => 6
    )
)

我花了差不多3天的时间来解决这个问题，直到写这篇文章，我才能做到这一点

$result = array();
$dates = array();
foreach ($inventory as $key => $item) {
    foreach ($item['sold'] as $k => $v) {
        array_push($dates, $v['date']);
    }
}
$dates = array_unique($dates);
foreach($dates as $key => $value) {
    array_push($result, array('date' => $value));
}
foreach ($dates as $rkey => $rvalue) {
    foreach ($inventory as $key => $item) {
        foreach ($item['sold'] as $k => $v) {
            if ($v['date'] = $result[$key]['date']) {
                array_push($result[$key][$item['item']] = $v['quantity']);
            }
        }
    }
}
return $result;

这当然给了我这个悲伤的结果

Array
(
[0] => Array
    (
        [date] => 2017-10-28
        [NK] => 1
    )
[1] => Array
    (
        [date] => 2017-10-29
        [FL] => 2
    )
)

更糟糕的是，我们有关于圈复杂度的规则，我们应该只有最多3个循环/条件，每个循环/条件最多3个嵌套级别。并且整个组织不应该有任何用户创建的功能。

即使不遵守规则，我也无法解决好几天。对不起，如果问题很长。请帮忙:(

Answer 1

我不知道这是否与Erwin的代码差不多，但是我在13小时前编写了这段代码，不得不等待阵列。

编辑;我测试了Erwin的代码，似乎我们已经接近匹配的代码了。他做了一个循环来获取日期，但它或多或少相同。

我循环播放阵列并销售子阵列我将新数组键设为日期示例：

Echo $new['2017-10-28']['nk']; // 11

如果没有设置日期键，我就创建它。

循环完成后，我使用array_values删除日期键，使数组看起来像：

Echo $new[0]['nk']; // 11

代码：

$new =[];

Foreach($inventory as $sub){
    Foreach($sub["sold"] as $sold){
        If (!isset($new[$sold["date"]]["date"])) $new[$sold["date"]]["date"] = $sold["date"];
        $new[$sold["date"]][$sub["item"]] =  $sold["quantity"];
    }
}
$new = array_values($new);
Var_dump($new);

我已经完成了一些测试和解决方法，并提出了这个解决方案。我设法使用ksort()，array_values()和array_key_exists()来实现这一目标。我首先使用日期作为数组键来包含该日期销售的所有商品。然后，在收集所有项目后将其移动到数组内部，然后重新编号数组。通过代码注释进一步解释

// result array
$result = array();

// Loop for each item on inventory
foreach ($inventory as $inv) {
    // Loop for each sold array
    foreach ($inv['sold'] as $item) {
        // date sold
        $date = $item['date'];
        // Check if date already exist in result array as key
        // If not, Create new array with key equal to date and push to result array
        if (!array_key_exists($date, $result)) {
            $result[$date] = array();
        }
        // Add array of item  =>  quantity to corresponding date array inside result array
        $result[$date][$inv['item']] = $item['quantity'];
    }
}
// From here you already have each item  =>  quantity sold inside each date array
// e.g. $result = array( '2017-10-28'  =>  array('NK'  =>  '11', 'FL'  =>  '7', ...) );

// Sort keys which are dates ascending
ksort($result);
// Loop to results and set
foreach ($result as $key  =>  $value) {
    $result[$key]['date'] = $key;
}
// Renumber Keys
$result = array_values($result);

// Print result
echo '<pre>';
print_r($result);

输出

Array

[0] => Array
    (
        [NK] => 11
        [FL] => 7
        [AD] => 5
