   The IteratorIterator class Introduction ¶ This iterator wrapper allows the conversion of anything that is Traversable into 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.

   What is a custom iterator in PHP?

   • PHP's Iterator interface defines five methods that any iterator must implement: Let's start with a simple example to illustrate how a custom iterator works. Imagine we have a class called WeekDays that we want to make iterable. We'll create a custom iterator that allows us to loop through the days of the week.

   What is a filtering iterator in PHP?

   • Filtering iterators are a subset of PHP iterators that allow you to iterate over data structures while applying filters or conditions to include or exclude elements. This selective processing can help streamline your code and improve performance by reducing unnecessary data processing. PHP provides several built-in filtering iterators.

   • "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).
