If you have been following the progress of PHP since version 5.6, even 7.4, you know there have been a lot of changes. How does that work? How does that happen? How do I get involved? To get you started on your way, let’s understand what an RFC is: *Request for Comments*. That doesn’t really explain a lot, but it’s the beginning of the discussion on a new implementation, change, or feature added or made in the underlying PHP engine by the internals team. This is the place where *all* of those discussions begin.
