Question

Rest API获得了一系列数据。我正在尝试从这些数据制作菜单，但是为此，我需要就嵌套进行转换（我认为这是循环完成的）

我在互联网上翻遍，到处都有通常的数字id递归，而我的id是一个字符串，结果我尝试通过foreach自己完成，

 foreach ($elements as $item){

     $thisRef = &$ref[$item['objectId']];

     $thisRef['parent'] = &$item['parent'];
     $thisRef['name'] = $item['property']['ru']['value'];
     $thisRef['objectId'] = $item['objectId'];
     $thisRef['number'] = $item['number'];
   $thisRef['duration'] = $item['duration'];
     $thisRef['object'] = $item['object'];
     $thisRef['listorder'] = $item['listorder'];

    if($item['parent'] == 0) {
         $items[$item['objectId']] = &$thisRef;
    } else {

    $ref[$item['parent']]['child'][$item['objectId']] = &$thisRef;       



    }


  }



 print_r($items);

我写的循环效果不佳，它只显示了一个直到2级的分支

$ elements数组在下面的print_r和var_export中传播

[objectId]是商品的ID

[parent]是元素的父级，它引用父级的objectId，如果为空或等于0，则没有父级

提出提供无限嵌套解决方案的强烈要求。

我希望你能帮助我。

通过print_r排列

通过var_export数组

Answer 1

我相信您想遍历所有项目，当前项目为$current。如果它具有父对象，请找到父对象$parent，然后将该项目添加到父对象的子数组（$parent.children[] = $current）。

// Loop through all
foreach ($elements as $current) {
  if (!empty($current['parent'])) {
    // Loop through all if they have a parent
    foreach ($elements as $parent) {
      // Add $current as a child if this is the parent
      if ($current['parent'] === $parent['objectId']) {
        $parent['children'][] = $current;
      }
    }
  }
}

如果只希望在数组中有父项，则可以通过检查元素是否没有父项来unset()或仅创建一个新数组。

尝试一下：

function cascadeElements($elements, &$result, $index = 0, $parent = null) {       
    $next = function () use ($elements, &$result, $index, $parent) {
        cascadeElements($elements, $result, ++$index, $parent);
    };

    if ($index >= count($elements)) {
        return;
    }

    $element = $elements[$index];

    if (!$parent && $element['parent'] !== null) {           
        return $next();
    }

    if ($parent && $element['parent'] !== $parent['objectId']) {
        return $next();
    }

    $element['children'] = [];

    cascadeElements($elements, $element['children'], 0, $element);

    $result[$element['objectId']] = $element;

    return $next();
}

您可以这样使用它：

$result = [];
cascadeElements($data, $result);

$result将充满objectId键控元素层次结构列表，其中每个元素在children键下具有其子元素。

此功能应可用于无限量的嵌套。
