        echo     date("Y-m-d H:i:s - ");
            printf("%s (%s): %s\n", module2string($module), level2string($level), $message);
    }

    MongoLog::setLevel(MongoLog::ALL);
    MongoLog::setModule(MongoLog::ALL);

    // We specify the function name here, but any callable (e.g. anonymous function) will work
