session_encode — Encodes the current session data as a session encoded string
session_encode() returns a serialized string of the contents of the current session data stored in the $_SESSION superglobal.
By default, the serialization method used is internal to PHP, and is not the same as serialize(). The serialization method can be set using session.serialize_handler.
This function has no parameters.
Returns the contents of the current session encoded, or false on failure.
Must call session_start() before using session_encode().
