Symfony\Component\HttpFoundation\Session\Storage\NativeSessionStorage::loadSession
Load the session with attributes.
After starting the session, PHP retrieves the session from whatever handlers are set to (either PHP's internal, or a custom save handler set with session_set_save_handler()). PHP takes the return value from the read() handler, unserializes it and populates $_SESSION with the result automatically.
Signature

$session = null] )

$session
