Of course not!
Each user has its own session_id. The $ _ SESSION is accessed through this session_id, so it will not be confused.

Each visitor's Session is different and will not be overwritten. The web framework injects a special cookie into the client to identify each visitor. The cookie keys of different web frameworks are different.
