php 使用kafka

<?php

$conf = new \RdKafka\Conf();
//捕获错误的回调
$conf->setErrorCb(function ($kafka, $err, $reason) {
    \Log::error('kafkaError', ['errorStr' => rd_kafka_err2str($err), 'err' => $err, 'reason' => $reason, 'content' => $kafka]);
});

$rk = new \RdKafka\Producer($conf);
$rk->setLogLevel(LOG_DEBUG);
$rk->addBrokers($this->url);

$topic = $rk->newTopic($this->topic);
//写kafka
$topic->produce(RD_KAFKA_PARTITION_UA, 0, $str);
$rk->poll(0);
