Where are thee, recursive copy command in PHP?

Trolling the Internet today reveals only a few candidates for a recursive copy function in PHP. There is something buried in a Cake PHP library, and also an odd function that doesn’t entirely work.

Is this conceptually difficult? Why is there so little information about performing this basic task?

Evidently as part of the PHP 5 SPL several iterators can do the job, leaving the developer only to mix in a few of the normal CRUD operations with these handy classes.
