Answer 1

Here's how I did it:

$gcm_result = $gcm->send_notification($registration_ids, $message);
$jsonArray = json_decode($gcm_result);

if(!empty($jsonArray->results)){

    $remove_ids = array();

    for($i=0; $iresults);$i++){
        if(isset($jsonArray->results[$i]->error)){
            if($jsonArray->results[$i]->error == "NotRegistered"){
                $remove_ids[$i] = "'".$registration_ids[$i]."'";
            }
        }
    }

    if(!empty($remove_ids)){

        $remove_ids_string = implode(', ',$remove_ids);
        include_once SCRIPTS.'gcm_server_php/db_functions.php';
        $dbf = new DB_Functions();
        $res = $dbf->deleteUsers($remove_ids_string);
        echo count($remove_ids)." users have unregistered from notifications since the last one was sent out.";

    }
}
