我已经工作了好几个小时，我的头都快碎了。拜托，谁能告诉我如何限制孩子返回的深度？
我想得到这个结构的一部分。例如：以 ID 118 为基础，从该 ID 中返回没有父母和 1 级子级。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;
$结果：
大批
(
[0] => 数组
(
[id] => 118
[父] => 12
[用户名] => Usuários
[孩子] => 数组
(
[0] => 数组
(
[id] => 1200
[父] => 118
[用户名] => 地籍
)
[1] => 数组
(
[id] => 1303
[父] => 118
[用户名] => Grupos
)
[2] => 数组
(
[id] => 1201
[父] => 118
[用户名] => Permissões
)
[3] => 数组
(
[id] => 1202
[父] => 118
[用户名] => Minha Conta
[孩子] => 真的
)
)
)
)
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 $ID. if 0(zero) no return childrens;
函数 TreePartByID($ID, $parents=0, $childrens=1){
...
返回 $arrayResult;
}
TreePartByID(118) 结果：o 完成引用 ao 项目 118 的路径
