session_unregister - Unregister a global variable from the current session
SYNOPSIS
bool session_unregister (string $name)
DESCRIPTION
session_unregister(3) unregisters the global variable named $name from the current session.
Warning
This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.
PARAMETERS
o $name
- The variable name.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
NOTES
Note
If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset(3) to unregister a session variable. Do not
unset(3)$_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(3) to remove the corresponding global variable.
Caution
If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(3), session_is_registered(3) and session_unregis-
ter(3).
