To follow up with the group, I received an answer via e-mail within a
few minutes with two methods (thanks AB).
(1)
$foo = @$HTTP_COOKIE_VARS["foo"];
# Where the @ suppresses the warnings on the call.
if ($foo)
{
}
(2) The one I ended up using (modified a bit):
if ((isset($HTTP_COOKIE_VARS["foo"]) and ($HTTP_COOKIE_VARS["foo"] ==
'value'))
{
}
PHP short circuits the logic so method 2 doesn't throw the error on the
value test. Or of course you can put the test for the value inside the if
{}. Also for environment variables you can use getenv() rather than the
array.
