Ah, good catch. Use that instead of my second example. If register_globals
is ON, it appears that session_unset() will take care of getting rid of the
global variables made.

John overlooked that function, and instead looped through the
variables in php instead. This would be used if you have
register_globals on and choose to use sessions insecurely.

With register_globals OFF:
$_SESSION = array();
If register_globals is ON and you want to get rid of $val1, $val2,
$val3,
etc... then:
foreach($_SESSION as $key => $value)
{ unset($$key); }
