start()
start() : boolean
Starts the session.
Throws
- \RuntimeException
If something goes wrong starting the session.
Returns
boolean —True if started.
StorageInterface.
regenerate(boolean $destroy = false, integer $lifetime = null) : boolean
Regenerates id that represents this storage.
This method must invoke session_regenerate_id($destroy) unless this interface is used for a storage object designed for unit or functional testing where a real PHP session would interfere with testing.
Note regenerate+destroy should not clear the session data in memory only delete the session data from persistent storage.
Care: When regenerating the session ID no locking is involved in PHPs session design. See https://bugs.php.net/bug.php?id=61470 for a discussion. So you must make sure the regenerated session is saved BEFORE sending the headers with the new ID. Symfonys HttpKernel offers a listener for this. See Symfony\Component\HttpKernel\EventListener\SaveSessionListener. Otherwise session data could get lost again for concurrent requests with the new ID. One result could be that you get logged out after just logging in.
| boolean | $destroy | Destroy session when regenerating? |
| integer | $lifetime | Sets the cookie lifetime for the session cookie. A null value will leave the system settings unchanged, 0 sets the cookie to expire with browser session. Time is in seconds, and is not a Unix timestamp. |
If an error occurs while regenerating this storage
True if session regenerated, false if error
save()
Force the session to be saved and closed.
This method must invoke session_write_close() unless this interface is used for a storage object design for unit or functional testing where a real PHP session would interfere with testing, in which case it it should actually persist the session data if required.
If the session is saved without being started, or if the session is already closed.
getBag(string $name) : \Symfony\Component\HttpFoundation\Session\SessionBagInterface
Gets a SessionBagInterface by name.
| string | $name |
If the bag does not exist
registerBag(\Symfony\Component\HttpFoundation\Session\SessionBagInterface $bag)
Registers a SessionBagInterface for use.
