PHP的 - 创建一个从MySQL数据嵌套数组

问题描述

我有存储在一个表像这样一些数据：

I have some data stored in a table like so:

id  parent_id  name
1   0          Entry 1
2   0          Entry 2
3   0          Entry 3
4   1          Child of entry 1

我要变成一个嵌套数组，像这样：

I want to turn it into a nested array like so:

array(
    array(
        'id' => 1,
        'parent_id' => 0,
        'name' => 'Entry 1',
        'children' => array(...)
    ),
    ...
);

在理想情况下，就需要支持嵌套（儿童儿童）无限量。是我的表设置为支持这一点，如果是这样，我怎么会产生使用表中的数据这类型的数组？如果没有，我应该怎么设置我的表？

Ideally, it would need to support an infinite amount of nesting (children with children). Is my table set up to support this, if so, how would I generate this kind of array using the data in the table? If not, how should I set up my table?

推荐答案

这里有mysql中管理分层数据很好的说明：

这里是建设嵌套阵列的另一个很好的例子：

There is a very good description of managing hierarchical data in mysql here:managing hierarchical dataHere is another good example of building nested arrays:building nested arrays

您可以考虑使用嵌套集模型。如果你想查询的东西mutch它比你现在使用的邻接模式更好。

You may think about using the Nested Set model. If you are going to query stuff mutch it is better than the adjacency model you are using right now.
