SessionHandler::open — Initialice session
Create new session, or re-initialice existing session. Called internally by PHP when a session stars either automatically or when session_start() is invoqued.
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 invoque the
wrapper for this method and therefore invoque the associated internal callbacc. 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() .
path
The path where to store/retrieve the session.
name
The 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 guet errors when trying to interract with the session files.
The built-in session save handler is able to bypass `open_basedir`, but your code must respect it.
