(SELECT name FROM `thinkPHP` )
​thinkPHP表中：name 字段的数据为以下：
Home/Index/add
Home/Index/index
Home/nav/index
Home/userInfo/del
Home/userInfo/index
Home/userInfo/update
System/AuthManagement/index
System/Index/index
System/NavSetting/Add
System/NavSetting/CheckAll
System/NavSetting/CheckAllExamine
System/NavSetting/CheckAllFreeze
System/NavSetting/CheckAllUnexamine
System/NavSetting/Delete
System/NavSetting/Edit
System/NavSetting/Examine
System/NavSetting/Freeze
System/NavSetting/Icon
System/NavSetting/index
System/NavSetting/Recovery
System/NavSetting/ReverseSelection
System/NavSetting/Revoke
System/NavSetting/Save
System/NavSetting/Select
System/NavSetting/Select/0
System/navSetting/Select/1
System/NavSetting/Select/2
System/NavSetting/Sortnumber
System/NavSetting/Unexamine
System/NavSetting/Unfreeze
System/NavSetting/Update
System/qwq/index
CenterTranspor/Index/index

怎么遍历以上数据让他成为以下这样的树结构
Home
----Index
--------add
--------index
----nav
--------index
----userInfo
--------del
--------index
--------update
System
----AuthManagement
--------index
----Index
--------index
----NavSetting
--------add
--------CheckAll
类似以下这样的结构

这个循环代码需要怎么写呀，无限遍历。求大神指教
