   How do recursive iterators work?

   • This class operates on a tree of elements, which is build by nesting recursive iterators into one another. Thus you might say it is an iterator over iterators. While traversing those, the class pushes the iterators on a stack while traversing down to a leaf and removes them from the stack while going back up.

   How do I set a recursive iterator key?

   • The key is in traversing back up the tree to save the changes at that level - simply calling $recursiveIterator->offsetSet (); will only set a key on the root array. A very important thing to note about \RecursiveIteratorIterator is that it returns a flattened array when used with the iterator_to_array function. Ex:

   Why is iterator_to_array a recursive class?

   • Carefull when using iterator_to_array (). Because it flattens down your subiterators, elements with the same keys will overwrite eachother. This class operates on a tree of elements, which is build by nesting recursive iterators into one another. Thus you might say it is an iterator over iterators.
