SessionHandlerInterface::write

Write session data

ENTITY

Writes the session data to the session storage. Called by session_write_close, when session_register_shutdown fails, or during a normal shutdown. Note: SessionHandlerInterface::close is called immediately after this function.

PHP will call this method when the session is ready to be saved and closed. It encodes the session data from the $_SESSION superglobal to a serialized string and passes this along with the session ID to this method for storage. The serialization method used is specified in the session.serialize_handler setting.

Note this method is normally called by PHP after the output buffers have been closed unless explicitly called by session_write_close

ENTITY

id
The session id.

data
The encoded session data. This data is the result of the PHP internally encoding the $_SESSION superglobal to a serialized string and passing it as this parameter. Please note sessions use an alternative serialization method.
