[RFC][Discussion] Add session_create_id()

>> Session ID can be non HEX strings. session_create_id() makes custom >> session ID creation easier. >> https://wiki.php.net/rfc/session-create-id >> >> Please note that the implementation was in the session.c years ago. >> The patch enables and add test for it. > > I like the idea, but I would add a bit more details - where the ID comes > from? Can I control it, and if so, how? Is uniqueness ensured and if > not, how one is recommended to deal with it? Some code examples would > help too. Some of it may be obvious to people who have been discussing > session stuff for years now, but the RFC should be accessible to > everybody, not just those participating is specific discussion. Ideally, > one should be able to understand the RFC by knowing only what the PHP > manual says and reading the RFC text.
