我已经工作了几个小时，我的头都开裂了。拜托，任何人都可以告诉我如何限制孩子们返回的深度吗？
我想参与这个结构。例如：对于基于ID 118的情况，此ID不返回任何父母和1个子级的孩子。 他们调用一个函数：
$result = TreePartByID($source, 118, null, 1);
$source Is the full array structure;
118 Is the ID to use as item base;
null Is the number of parents to return from the ID 118. In this case, null represents the some iten with ID 118;
1 Is a depth of childrens to return from ID 118. This case is only immediate childrens relative to ID 118;
$ result：
Array
(
[0] => Array
(
[id] => 118
[parent] => 12
[username] => Usuários
[children] => Array
(
[0] => Array
(
[id] => 1200
[parent] => 118
[username] => Cadastro
)
[1] => Array
(
[id] => 1303
[parent] => 118
[username] => Grupos
)
[2] => Array
(
[id] => 1201
[parent] => 118
[username] => Permissões
)
[3] => Array
(
[id] => 1202
[parent] => 118
[username] => Minha Conta
[children] => true
)
)
)
)
功能：
参数：
$ID = ID of iten defined as default;
$parents = Number of parents from the $ID. If null, retur the own $ID, else if 0(zero) return from the root and any number is the number of parents;
$childrens = Number of childrens from the $ID. if 0(zero) no return childrens;
function TreePartByID($ID, $parents=0, $childrens=1){
...
return $arrayResult;
}
TreePartByID（118）结果：o路径完成引用了项目118
