__construct(array $options = array(), SessionHandlerInterface|null $handler = null, MetadataBag $metaBag = null)
Depending on how you want the storage driver to behave you probably want to override this constructor entirely.
List of options for $options array with their defaults.
Parameters
array | $options | Session configuration options |
SessionHandlerInterface|null | $handler | |
MetadataBag | $metaBag | MetadataBag |

AbstractProxy|SessionHandlerInterface getSaveHandler()
Gets the save handler instance.
Return Value
AbstractProxy|SessionHandlerInterface |
bool start()
Starts the session.
Return Value
bool | True if started |
Exceptions
RuntimeException | if something goes wrong starting the session |
string getId()
Returns the session ID.
Return Value
string | The session ID or empty |
setId(string $id)
Sets the session ID.
Parameters
string | $id |
mixed getName()
Returns the session name.
Return Value
mixed | The session name |
setName(string $name)
Sets the session name.
Parameters
string | $name |
bool regenerate(bool $destroy = false, int $lifetime = null)
Regenerates id that represents this storage.
This method must invoke sessionregenerateid($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 PHP's 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. Symfony's 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.
Parameters
bool | $destroy | Destroy session when regenerating? |
int | $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. |
Return Value
bool | True if session regenerated, false if error |
Exceptions
RuntimeException | If an error occurs while regenerating this storage |
save()
Force the session to be saved and closed.
This method must invoke sessionwriteclose() 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 should actually persist the session data if required.
Exceptions
RuntimeException | if the session is saved without being started, or if the session is already closed |
clear()
Clear all session data in memory.
registerBag(SessionBagInterface $bag)
Registers a SessionBagInterface for use.
Parameters
SessionBagInterface | $bag |
SessionBagInterface getBag(string $name)
Gets a SessionBagInterface by name.
Parameters
string | $name |
Return Value
SessionBagInterface |
Exceptions
InvalidArgumentException | If the bag does not exist |
setMetadataBag(MetadataBag $metaBag = null)
Parameters
MetadataBag | $metaBag |
MetadataBag getMetadataBag()
Gets the MetadataBag.
Return Value
MetadataBag |
bool isStarted()
Checks if the session is started.
Return Value
bool | True if started, false otherwise |
setOptions(array $options)
Sets session.* ini variables.
For convenience we omit 'session.' from the beginning of the keys. Explicitly ignores other ini keys.
Parameters
array | $options | Session ini directives array(key => value) |

setSaveHandler(SessionHandlerInterface|null $saveHandler = null)
Registers session save handler as a PHP session handler.
To use internal PHP session save handlers, override this method using iniset with session.savehandler and session.save_path e.g.
ini_set('session.save_handler', 'files');
ini_set('session.save_path', '/tmp');
or pass in a \SessionHandler instance which configures session.save_handler in the constructor, for a template see NativeFileSessionHandler or use handlers in composer package drak/native-session
Parameters
SessionHandlerInterface|null | $saveHandler |
Exceptions
InvalidArgumentException |
