我从一个表中得到以下数据:
+----+---------+-----+---------+--------------+
| id | name | id2 | sname | relation |
+----+---------+-----+---------+--------------+
| 1 | Albaraa | 2 | Brandon | Friend |
| 1 | Albaraa | 3 | Shen | Friend |
| 1 | Albaraa | 4 | Dan | Professor |
| 1 | Albaraa | 5 | Bob | Boss |
| 1 | Albaraa | 6 | Al | God Father |
| 2 | Brandon | 5 | Bob | Friend |
| 3 | Shen | 1 | Albaraa | Friend |
| 3 | Shen | 2 | Brandon | Friend |
| 3 | Shen | 4 | Dan | Professor |
| 4 | Dan | 1 | Albaraa | Student |
| 4 | Dan | 2 | Brandon | Student |
| 4 | Dan | 3 | Shen | Student |
| 5 | Bob | 6 | Al | Best Friend |
| 6 | Al | 1 | Albaraa | God Son |
| 6 | Al | 5 | Bob | Best Friends |
+----+---------+-----+---------+--------------+
我得到php数组格式的数据:
Array (
[0] => Array ( [id] => 1 [name] => Albaraa [id2] => 2 [sname] => Brandon [relation] => Friend )
[1] => Array ( [id] => 1 [name] => Albaraa [id2] => 3 [sname] => Shen [relation] => Friend )
[2] => Array ( [id] => 1 [name] => Albaraa [id2] => 4 [sname] => Dan [relation] => Professor )
[3] => Array ( [id] => 1 [name] => Albaraa [id2] => 5 [sname] => Bob [relation] => Boss )
[4] => Array ( [id] => 1 [name] => Albaraa [id2] => 6 [sname] => Al [relation] => God Father )
[5] => Array ( [id] => 2 [name] => Brandon [id2] => 5 [sname] => Bob [relation] => Friend )
[6] => Array ( [id] => 3 [name] => Shen [id2] => 1 [sname] => Albaraa [relation] => Friend )
[7] => Array ( [id] => 3 [name] => Shen [id2] => 2 [sname] => Brandon [relation] => Friend )
[8] => Array ( [id] => 3 [name] => Shen [id2] => 4 [sname] => Dan [relation] => Professor )
[9] => Array ( [id] => 4 [name] => Dan [id2] => 1 [sname] => Albaraa [relation] => Student )
[10] => Array ( [id] => 4 [name] => Dan [id2] => 2 [sname] => Brandon [relation] => Student )
[11] => Array ( [id] => 4 [name] => Dan [id2] => 3 [sname] => Shen [relation] => Student )
[12] => Array ( [id] => 5 [name] => Bob [id2] => 6 [sname] => Al [relation] => Best Friend )
[13] => Array ( [id] => 6 [name] => Al [id2] => 1 [sname] => Albaraa [relation] => God Son )
[14] => Array ( [id] => 6 [name] => Al [id2] => 5 [sname] => Bob [relation] => Best Friends ) )
我现在需要做的是将数据设置到一个数组中，该数组添加了第一个人，并从那里添加了他的孩子和孩子的孩子，它看起来像这样(使它看起来更容易读=]):
Array (
[id] => 0
[name] => Albaraa
[children] => Array (
[0] => Array (
[id] => 1
[name] => Brandon
[data] => Array (
[relationTo] => Albaraa
[relation] => Friend )
[children] => Array (
[id] => 2
[name] => Bob
[data] => Array (
[relationTo] => Brandon
[relation] => Friend )
[children] => Array()
)
...and so on
))
我有它的地方，它输出上面的，但没有孩子有任何孩子(只是一个空数组)我真的不确定如何让它正确做到这一点，我已经尝试过一个类做到这一点，但失败了…所以任何关于如何让数据看起来像上面一个的帮助将非常感激!
这里有一种PHP方法可以做到这一点，根本没有进行太多优化。您可能也可以使用SQL连接来获得一个看起来非常接近结果的数组。
// set root stuff
$person1 = $arr[0];
$new_arr = [];
$new_arr['id'] = 0;
$new_arr['name'] = $arr['name'];
// find children
foreach ($arr as $child){
// if found child
if ($child['sname'] == $person1['name']){
// set data
$child_arr = [];
$child_arr['id'] = $child['id'];
$child_arr['name'] = $child['name'];
$child_arr['data']['relationTo'] = $child['sname'];
$child_arr['data']['relation'] = $child['relation'];
$new_arr['children'][] = $child_arr;
// find grandchildren
foreach ($arr as $gc){
// if found grandchild
if ($gc['sname'] == $child['name']){
// set data
$gc_arr = [];
$gc_arr['id'] = $gc['id'];
$gc_arr['name'] = $gc['name'];
$gc_arr['data']['relationTo'] = $gc['sname'];
$gc_arr['data']['relation'] = $gc['relation'];
$gc_arr['children'] = []; // assuming you didn't want to go deeper
$child_arr['children'][] = $gc_arr;
}
}
}
}
如果你想更深入，我们需要引入递归
