Description
bool session_unregister ( string $name )
session_unregister() unregisters the global variable named name
from the current session.
Warning

Parameters
name
The variable name.
Return Values
Returns TRUE
on success or FALSE
on failure.
Notes
Note: If $_SESSION is used, use unset() to unregister a session variable. Do not unset() $_SESSION itself as this will disable the special function of the $_SESSION superglobal.
Caution
This function does not unset the corresponding global variable for name
, it only prevents the variable from being saved as part of the session. You must call unset() to remove the corresponding global variable.
Caution
If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().
