SessionHandler::open — Initialize session
Create new session, or re-initialize existing session. Called internally by PHP when a session starts either automatically or when session_start() is invoked.
This method wraps the internal PHP save handler defined in the session.save_handler ini setting that was set before this handler was set by session_set_save_handler().
If this class is extended by inheritance, calling the parent open method will invoke the
wrapper for this method and therefore invoke the associated internal callback. This allows this method to be
overridden and or intercepted and filtered.
For more information on what this method is expected to do, please refer to the documentation at SessionHandlerInterface::open().
pathThe path where to store/retrieve the session.
nameThe session name.
If you are creating a custom session handler that uses files, note that if you have set the `open_basedir` configuration and the session file path is not inside a path declared in that configuration, you will get errors when trying to interact with the session files.
The built-in session save handler is able to bypass `open_basedir`, but your code must respect it.
