SESSION_UNSET(3) 1 SESSION_UNSET(3)
session_unset - Free all session variables
SYNOPSIS
void session_unset (void )
DESCRIPTION
The session_unset(3) function frees all session variables currently registered.
RETURN VALUES
No value is returned.
NOTES
Note
If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use unset(3) to unregister a session variable, i.e. unset
($_SESSION['varname']);.
Caution
Do NOT unset the whole $_SESSION with unset($_SESSION) as this will disable the registering of session variables through the $_SES-
SION superglobal.
