Question

我正在尝试使多维数组构建一个添加hr字段的数组路径，使其看起来像这样：

我只是无法弄清楚如何添加总数，也无法创建子数组，因此选项中的点符号也是如此。 我的目标是获得类似的内容：

      [1] => [1][2][1][5][0][6] = 35 (the second child path "1")
      [1] => [1][2][1][5][0][7] = 25

或类似的内容：

   array (
      [children.0.children.0.children.0.total] = 20
      [children.0.children.1.children.1.total] = 35
      // etc
   )

复杂的部分是它向不同的方向发展，我想知道基于路径的最高和最低总数是多少：

    $iter = new RecursiveIteratorIterator(new RecursiveArrayIterator($myArray));
    $result = array();
    foreach ($iter as $leafKey => $leafValue) {
        $keys = array();
        foreach (range(0, $iter->getDepth()) as $depth) {
            $keys[] = $iter->getSubIterator($depth)->key();
        }
        $result[ join('.', $keys) ] = $leafValue;
    }

    return $result;
}

$result = doit($tree);

print_r($result);

这似乎有效，我发现它整天都在谷歌搜索。

mydict = {"Pens": 1, "Pencils": 2, "Paper": 3}
with open('myfile.json' , 'r+') as f:
   d = json.load(f)
   d.update(mydict)
   f.seek(0)
   json.dump(d, f)

递归地从另一个数组创建一个数组
