Overview:

One of PHP5's most interesting new features is the addition of Iterators, a collection of ready-made interfaces designed to help in navigating and processing hierarchical data structures. These Iterators significantly reduce the amount of code required to process an XML document tree or a file collection. The DirectoryIterator provides a quick and efficient way of processing the files in a directory; with a little creative coding, it can also be used to recursively process a nested directory tree. Both these tasks can be accomplished using just a few lines of code, representing a significant improvement over the "standard" way of doing things.
