I am trying the code on this page https://help.exacttarget.com/en/technical_library/web_service_guide/technical_articles/managing_subscriber_status_for_one_or_all_lists/
$subscriber = new ExactTarget_Subscriber(); //If you create the new subscriber object . . . $subscriber->EmailAddress = $email; //. . . and specify the email address belonging to the subscriber . . . $subscriber->SubscriberKey = $subscriberkey; //. . . as well as the subscriber key of the subscriber . . . $subscriber->Status = "Unsubscribed"; //. . . then you can specify a status of Unsubscribed (that subscriber won't receive messages sent to all lists in your account.
to update a subscriber status, but it does not seem to work. The code seems simple. Did I miss something? Has anyone had experience with this? I'd rather stay away from the Fuel SDK, because so far I'm using the native ET code structure. Thanks!
