Like others, I'm skeptical of the behavior here not being all that clear.
What several other languages do, and what I have in the plan for collections if/when they ever happen, is sort() sorts in place, while sorted() returns a new value. There's similarly reverse() (in place) and reversed() (new value returned).
*sorted($arr) seems like it would be a lot less confusing, and consistent with what other languages (and hopefully future PHP) do. (I don't know what that means for array_walk(), but I don't know what that would even return anyway.)
