  4. Simple usage example of `RecursiveTreeIterator::next ()`. The RecursiveTreeIterator::next function is used to move the iterator to the next element in a tree structure. It allows traversal through a tree-like data structure, visiting each element in a depth-first manner. This function is particularly useful when working with nested data structures, such as multi-level arrays or object hierarchies.
