If you enable <link
linkend="ini.register-globals"><literal>register_globals</literal></link>,
<function>session_unregister</function> should be used since
session variables are registered as global variables when
session data is deserialized. Disabling <link
linkend="ini.register-globals"><literal>register_globals</literal></link>
is recommended for both security and performance reason.
