(PHP 5 >= 5.4.0)
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.
If this class is extended by inheritiance, calling the parent
open method will invoke the wrapper for this method and therefor invoke the associated internal callback. This allows this method to be overidden and or intercepted and filtered.
For more information on what this method is expected to do, please refer to the documentation at SessionHandlerInterface::open().
The path where to store/retrieve the session.
The session id.
The return value (usually
TRUE on success,
FALSE on failure). Note this value is returned internally to PHP for processing.
