The answer for the deep copy would seem to be a combination of a static recursive function to copy the array while cloning the objects inside, with setting the __clone() magic function in your objects to break the references, no? Granted it’s not a built in function, but not difficult to implement.
Sorry for being lazy so no sources for now. But based on my research back then. Using clone (on arrays) is actually slower then json_encode/json_decode.
So there are some cool optimization tricks going on in the background. But that doesn’t make it any more intuitive for me.
