$conf->set('sasl.username', "???");
$conf->set('sasl.mechanism', "PLAIN");
$conf->set('sasl.password', "???");
$conf->set('log_level', (string) LOG_DEBUG);
$conf->set('debug', 'all');
$producer = new RdKafkaProducer($conf);
$producer->addBrokers($broker_list);
$topic = $producer->newTopic($topic_name);

Answer

Are you trying to connect to confluent cloud?

I would add to your conf your security protocol, as you indicate sasl. eg $conf->set(‘security.protocol’,’sasl_ssl’);

I would think you would not need to indicate the brokers in the producer, as you have already done this in the config. I am presuming your broker list is a csv formatted file that include host and port number?
