Php learning session the program developed in the old php version, the session registered using the register_session statement does not take effect in php 5. the solution is to set the php. ini:
Register_globals = On
This option is set to Off in php4 and 5 by default.

If $ _ SESSION is used, do not use session_register (), session_is_registered (), session_unregister ().

If you have not called session_start () before register_session, it is called implicitly. Session_start () must be manually called when $ _ SESSION is used ()
