How to properly remove sessions from a directory?

Question

PHP

Tell me how to delete the session file correctly (I save it in a directory, the lifetime is a month).
When a user logs out, it is necessary to delete the session file, how can this be done more correctly?
Leaving and waiting for the garbage collector to come is nonsense because everyone will do this several times and inodes will end and there will be tons of sessions.
How to properly delete the session file?

Answer 1

1) do not store authorization information in sessions - cookies with access_token are suitable for this;
2) write your own implementation of sessions (based on the database)
