Remember doing something like this in the past... $input = array(3, 'bar', 'baz'); $iterator = new ArrayIterator($input); $iterator->seek(2); echo $iterator->current(); $iterator->seek(0); echo $iterator->current(); $iterator->seek(5); // throws OutOfBoundsException Though a specific function does make sense, imo.
