Call to undefined method RdKafka\KafkaConsumer::newTopic() about php-rdkafka HOT 6 CLOSED

$consumer is object ?
metadata.broker.list must like this, 127.0.0.1:port

from php-rdkafka.

it's not the problem.

I found the code not registered function newTopic in file kafka_consumer.c

PHP_ME(RdKafka__KafkaConsumer, newTopic, arginfo_kafka_kafka_consumer_new_topic, ZEND_ACC_PUBLIC)

in line 635 It is that:

static const zend_function_entry fe[] = { /* {{{ */
    PHP_ME(RdKafka__KafkaConsumer, __construct, arginfo_kafka_kafka_consumer___construct, ZEND_ACC_PUBLIC)
    PHP_ME(RdKafka__KafkaConsumer, assign, arginfo_kafka_kafka_consumer_assign, ZEND_ACC_PUBLIC)

@breath-co2 high level interface use subscribe like this:
$this->rk = new \RdKafka\KafkaConsumer($this->conf);
$this->rk->subscribe([$topic]);

newTopic is simple insterface. the code at rdkafka.c

from php-rdkafka.

@doubleycn I need get object \RdKafka\KafkaConsumerTopic

https://arnaud-lb.github.io/php-rdkafka/phpdoc/class.rdkafka-kafkaconsumertopic.html
The document page write that:

This class represents a topic when using the RdKafka\KafkaConsumer. It can not be instantiated directly, RdKafka\KafkaConsumer::newTopic() should be used instead.

from php-rdkafka.

@breath-co2 do you want to use RdKafka\KafkaConsumerTopic::offsetStore ? you can use this methed.
`
ZEND_BEGIN_ARG_INFO_EX(arginfo_kafka_kafka_consumer_commit, 0, 0, 0)
ZEND_ARG_INFO(0, message_or_offsets)
ZEND_END_ARG_INFO()

PHP_METHOD(RdKafka__KafkaConsumer, commit)
{
consumer_commit(0, INTERNAL_FUNCTION_PARAM_PASSTHRU);
}
example:
$conf = new RdKafka\Conf();
$conf->set("metadata.broker.list", "xxxx:8092");
$conf->set("group.id", "test-group");
//$conf->set("enable.auto.commit", "false");
//$conf->set("enable.auto.offset.store", "false");
//$conf->set("auto.offset.reset", 'smallest');

$consumer = new RdKafka\KafkaConsumer($conf);
$consumer->subscribe(["test"]);

while (true) {
$message = $consumer->consume(100e2);
switch ($message->err) {
case RD_KAFKA_RESP_ERR_NO_ERROR:
$consumer->commit($message);
var_dump($message);
break;
case RD_KAFKA_RESP_ERR__PARTITION_EOF:
break;
default:
var_dump($message->errstr());
}
break;
}
