SESSION_UNREGISTER(3) 1 SESSION_UNREGISTER(3)session_unregister - Unregister a global variable from the current sessionSYNOPSIS
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).

SUPERGLOBALS(3) 1 SUPERGLOBALS(3)Superglobals - Superglobals are built-in variables that are always available in all scopes
Several predefined variables in PHP are "superglobals", which means they are available in all scopes throughout a script. There is no need
to do global $variable; to access them within functions or methods.
These superglobal variables are:
o$GLOBALS
o$_SERVER
o$_GET
o$_POST
o$_FILES
o$_COOKIE
o$_SESSION
o$_REQUEST
o$_ENV

Note
Variable availability
By default, all of the superglobals are available but there are directives that affect this availability. For further information,
refer to the documentation for variables_order.
Note
Dealing with register_globals
If the deprecated register_globals directive is set to on then the variables within will also be made available in the global scope
of the script. For example, $_POST['foo'] would also exist as $foo.
For related information, see the FAQ titled "How does register_globals affect me?"
Note
Variable variables
Superglobals cannot be used as variable variables inside functions or class methods.
