RecursiveIteratorIterator::current — Access the current element value
RecursiveIteratorIterator::getDepth — Get the current depth of the recursive iteration
RecursiveIteratorIterator::getSubIterator — The current active sub iterator
RecursiveIteratorIterator::key — Access the current key
RecursiveIteratorIterator::next — Move forward to the next element
RecursiveIteratorIterator::rewind — Rewind the iterator to the first element of the top level inner iterator
RecursiveIteratorIterator::valid — Check whether the current position is valid
