If <varname>$_SESSION</varname> (or

<varname>$HTTP_SESSION_VARS</varname> for PHP 4.0.6 or less) is
|
|
used, use <function>unset</function> to unregister a session
|

variable, i.e. <literal>unset ($_SESSION['varname']);</literal>.

<para>
|

Do NOT unset the whole <varname>$_SESSION</varname> with
|
|
<literal>unset($_SESSION)</literal> as this will disable the
|
|
registering of session variables through the
|
|
<varname>$_SESSION</varname> superglobal.
