How to create a nested array out of an array in PHP

Question

Say, we have an array: array(1,2,3,4,...) And I want to convert it to:

array(
    1=>array(
        2=>array(
            3=>array(
                4=>array()
            )
        )
    )
)

Can anybody help?
Thanks

EDIT It would be good to have the solution with iterations.
