session_unregister

(PHP 4, PHP 5)

session_unregister — Unregister a global variable from the current session

Description

bool session_unregister ( string $name )

session_unregister() unregisters the global variable named name from the current session.

Parameters

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() 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().
