Im trying to build a little site using XML instead of a database.

I would like to build a next and prev button which will work relative to the content I have displayed.

I found the php function next() and prev() as well as current() but I do not know how to set the pointer to a specific position to be able to navigate relative to the current page.

$list=array('page1','page2','page3')

eg if im displaying contents of page2 how could I tell php i am at $list[1] so that next($list) shows page3?

Thanks in advance

php xml arrays
