   www.php.net › manual › en

   The returned value from getInnerIterator() really is the inner iterator, not a clone. It should be used with respect: calling next() or rewind() on it, for example, will advance or reset the inner iterator - although the effect won't be noticed until you call next() on the IteratorIterator object - it seems as if it caches its current() and key ...

   Is IteratorIterator a nested foreach?

   • In other words, I believe IteratorIterator is the same as having nested foreach loops, without having to know all of the elements of each object. In other words, a nested foreach using object oriented objects... there's a redundant statement. :-)

   Can a recursive iterator be used in a PHP script?

   • "This is an internal engine interface which cannot be implemented in PHP scripts. Either IteratorAggregate or Iterator must be used instead." The site has some RecursiveIteratorIterator examples that might be handy but, if i get it right, IteratorIterator is from the scripting point of view pretty useless (when used to foreach at least).

   What if a class does not implement an iterator?

   • It is important to understand that most classes that do not implement Iterators have reasons as most likely they do not allow the full Iterator feature set. If so, techniques should be provided to prevent misuse, otherwise expect exceptions or fatal errors. public getInnerIterator (): ?

   Sep 2, 2009 · 5 Try as I might I cannot get my head around what the IteratorIterator class actually does. I understand that classes can implement Traversable so the engine knows it can loop using foreach and I realise that IteratorIterator is supposed to convert anything that is Traversable into an Iterator but I cannot for the life of me understand how.
