array into tree

[jansky]

hi guys

i think im lost on how to generate array (multi dimensional) into tree construct

here is a sample array

Array
(
[0] => Array
(
[NextPagePath] => /yhteydenottolomakkeen/
[PreviousPath] => /caset/
[TimeOnpage] => 3
)

[1] => Array
    (
        [NextPagePath] => /
        [PreviousPath] => /
        [TimeOnpage] => 9
    )

[2] => Array
    (
        [NextPagePath] => /caset/
        [PreviousPath] => /
        [TimeOnpage] => 9
    )

[3] => Array
    (
        [NextPagePath] => /
        [PreviousPath] => (entrance)
        [TimeOnpage] => 9
    )

now when this array converted into tree it should look like

+(entrance) or "/"
- caset
* yhteydenottolomakkeen
- /

how would i do this one

your help is highly appreciated

Tnx
