Kafka-php

中文文档

Kafka-php is a pure PHP kafka client that currently supports greater than 0.8.x version of Kafka, this project v0.2.x and v0.1.x are incompatible if using the original v0.1.x You can refer to the document Kafka PHP v0.1.x Document, but it is recommended to switch to v0.2.x . v0.2.x use PHP asynchronous implementation and kafka broker interaction, more stable than v0.1.x efficient, because the use of PHP language so do not compile any expansion can be used to reduce the access and maintenance costs

Requirements

• Minimum PHP version: 7.1
• Kafka version greater than 0.8
• The consumer module needs kafka broker version greater than 0.9.0

Installation

Add the lib directory to the PHP include_path and use an autoloader like the one in the examples directory (the code follows the PEAR/Zend one-class-per-file convention).

Composer Install

Simply add a dependency nmred/kafka-php to your project if you use Composer to manage the dependencies of your project.

$ composer require nmred/kafka-php

Here is a minimal example of a composer.json file :

{
	"require": {
		"nmred/kafka-php": "0.2.*"
	}
}

Configuration

Configuration properties are documented in Configuration

Producer

Asynchronous mode

<?php
require '../vendor/autoload.php';
date_default_timezone_set('PRC');
use Monolog\Logger;
use Monolog\Handler\StdoutHandler;
// Create the logger
$logger = new Logger('my_logger');
// Now add some handlers
$logger->pushHandler(new StdoutHandler());

$config = \Kafka\ProducerConfig::getInstance();
$config->setMetadataRefreshIntervalMs(10000);
$config->setMetadataBrokerList('10.13.4.159:9192');
$config->setBrokerVersion('1.0.0');
$config->setRequiredAck(1);
$config->setIsAsyn(false);
$config->setProduceInterval(500);
$producer = new \Kafka\Producer(
    function() {
        return [
            [
                'topic' => 'test',
                'value' => 'test....message.',
                'key' => 'testkey',
            ],
        ];
    }
);
$producer->setLogger($logger);
$producer->success(function($result) {
	var_dump($result);
});
$producer->error(function($errorCode) {
		var_dump($errorCode);
});
$producer->send(true);

Synchronous mode

<?php
require '../vendor/autoload.php';
date_default_timezone_set('PRC');
use Monolog\Logger;
use Monolog\Handler\StdoutHandler;
// Create the logger
$logger = new Logger('my_logger');
// Now add some handlers
$logger->pushHandler(new StdoutHandler());

$config = \Kafka\ProducerConfig::getInstance();
$config->setMetadataRefreshIntervalMs(10000);
$config->setMetadataBrokerList('127.0.0.1:9192');
$config->setBrokerVersion('1.0.0');
$config->setRequiredAck(1);
$config->setIsAsyn(false);
$config->setProduceInterval(500);
$producer = new \Kafka\Producer();
$producer->setLogger($logger);

for($i = 0; $i < 100; $i++) {
    $producer->send([
        [
            'topic' => 'test1',
            'value' => 'test1....message.',
            'key' => '',
        ],
    ]);
}

Consumer

<?php
require '../vendor/autoload.php';
date_default_timezone_set('PRC');
use Monolog\Logger;
use Monolog\Handler\StdoutHandler;
// Create the logger
$logger = new Logger('my_logger');
// Now add some handlers
$logger->pushHandler(new StdoutHandler());

$config = \Kafka\ConsumerConfig::getInstance();
$config->setMetadataRefreshIntervalMs(10000);
$config->setMetadataBrokerList('10.13.4.159:9192');
$config->setGroupId('test');
$config->setBrokerVersion('1.0.0');
$config->setTopics(['test']);
//$config->setOffsetReset('earliest');
$consumer = new \Kafka\Consumer();
$consumer->setLogger($logger);
$consumer->start(function($topic, $part, $message) {
	var_dump($message);
});
