Gonna vote no on this: please design new/dedicated functions, rather than expanding optional parameters.

I would vote no for the same reason.

Since this is explicitly an open question in the current RFC draft, it seems a bit premature to talk about voting, rather than encouraging the RFC to develop in a particular direction. For what it's worth, I agree that a new function is probably better here, because the argument list of array_column is already quite complicated. A new function also leaves the way open to add more functionality, such as the "reducer" callback suggested by Hendra Gunawan; I don't think that's needed in the first implementation, though. In general, I like the proposal - like array_column itself, it's one of those things that's fairly _simple_ to do in userland, but also fairly _often_ done, so compacting it to a neat function call seems useful.
