Kafka is a high-throughput distributed publish-subscribe messaging system that can handle all action streaming data in consumer-scale websites. Such actions (web browsing, searches and other user actions) are a key factor in many social functions on the modern web. This data is typically addressed by processing logs and log aggregation due to throughput requirements. For log data and offline analysis systems like Hadoop, but requiring real-time processing constraints, this is a feasible solution. The purpose of Kafka is to unify online and offline message processing through Hadoop's parallel loading mechanism, and to provide real-time consumption through clusters.
<?php
namespace Kafka;
class Broker
{
use SingletonTrait;
private $groupBrokerId = null;
private $topics = [];
private $brokers = [];
private $metaSockets = [];
private $dataSockets = [];
private $process;
private $socket;
private $config;
public function setProcess(callable $process)
{
$this->process = $process;

How does PHP integrate with message queuing systems (e.g., RabbitMQ, Kafka)?
10 Jun 2025
PHP integrates with RabbitMQ and Kafka and other message queue systems through dedicated libraries and extensions to realize message production and consumption. 1. Use the php-amqplib library or amqp extension to connect to RabbitMQ, declare queues and publish or consume messages; 2. Integrate PHP with Kafka through the php-rdkafka library, and configure producers or consumers to send or read messages; 3. When processing fails, make sure that messages are only confirmed after successful processing, and use dead letter queues, retry mechanisms and logging to avoid infinite loops; 4. In RabbitMQ, ack/nack can be used to control messages, and Kafka needs to manually submit offsets; 5. In terms of performance, it is recommended to use CLI scripts to run consumers.
