1、首先安裝kafka擴充

#安裝librdkafka:   版本： https://github.com/edenhill/librdkafka/releases/tag/v0.9.2$   git clone https://github.com/edenhill/librdkafka.git$  ./configure$  make$  sudo make install#安裝 rdkafka.so  版本：https://github.com/arnaud-lb/php-rdkafka/releases/tag/3.0.1$ git clone https://github.com/arnaud-lb/php-rdkafka.git$ cd php-rdkafka$ phpize$ ./configure$ make all -j 5$ sudo make install

2、生產者程式碼範例

  $rcf = new RdKafka\Conf();
    $rcf->set(‘group.id‘, ‘test‘);  //topicname
    $cf = new RdKafka\TopicConf();
    $cf->set(‘offset.store.method‘, ‘broker‘);
    $cf->set(‘auto.offset.reset‘, ‘smallest‘);
    $rk = new RdKafka\Producer($rcf);
    $rk->setLogLevel(LOG_DEBUG);
    $rk->addBrokers("127.0.0.1"); //brokeraddr
    $topic = $rk->newTopic("test", $cf);  //topicname
    for($i = 0; $i < 10; $i++) {
       $topic->produce(0,0,‘test‘ . $i);
     }

3、消費者程式碼範例

    $rcf = new RdKafka\Conf();
    $rcf->set(‘group.id‘, ‘test‘);
    $rcf->set(‘broker.version.fallback‘, ‘0.8.2‘);  //brokername,kafkaversion
    $cf = new RdKafka\TopicConf();
    $cf->set(‘auto.offset.reset‘, ‘smallest‘);
    $cf->set(‘auto.commit.enable‘, true);
    $rk = new RdKafka\Consumer($rcf);
    $rk->setLogLevel(LOG_DEBUG);
    $rk->addBrokers("127.0.0.1"); //brokeraddr
    $topic = $rk->newTopic("test", $cf);  //topicname,topicobject
    $topic->consumeStart(0,10);  //partition,offset
    $msg = $topic->consume(0, 1000);   //partition,timeout
    var_dump($msg);
