Kafka client written in PHP

Kafka-php uses a kafka client written in pure PHP. It currently supports versions of Kafka 0.8.x or above. The project v0.2.x is not compatible with v0.1.x. If you use the original v0.1 For .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 uses PHP asynchronous execution to interact with kafka broker, which is more stable and efficient than v0.1.x. Since it is written in PHP language, it can be used without compiling any extensions, which reduces access and maintenance costs.

Installation environment requirements

• PHP version is greater than 5.5

• Kafka Server version is greater than 0.8.0

• The consumption module Kafka Server version needs to be greater than 0.9.0

Installation

Use Composer to install

Add composer to depend on nmred/kafka -php to the composer.json file of the project, such as:

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

Produce

<?php require &#39;../vendor/autoload.php&#39;;
date_default_timezone_set(&#39;PRC&#39;);
use Monolog\Logger;
use Monolog\Handler\StdoutHandler;
// Create the logger
$logger = new Logger(&#39;my_logger&#39;);
// Now add some handlers
$logger->pushHandler(new StdoutHandler());

// 设置生产相关配置，具体配置参数见 [Configuration](Configuration.md)
$config = \Kafka\ProducerConfig::getInstance();
$config->setMetadataRefreshIntervalMs(10000);
$config->setMetadataBrokerList('10.13.4.159:9192');
$config->setBrokerVersion('0.9.0.1');
$config->setRequiredAck(1);
$config->setIsAsyn(false);
$config->setProduceInterval(500);
$producer = new \Kafka\Producer(function() {
	return array(
		array(
			'topic' => 'test',
			'value' => 'test....message.',
			'key' => 'testkey',
		),
	);
});
$producer->setLogger($logger);
$producer->success(function($result) {
	var_dump($result);
});
$producer->error(function($errorCode, $context) {
	var_dump($errorCode);
});
$producer->send();

Consumer

<?php require &#39;../vendor/autoload.php&#39;;
date_default_timezone_set(&#39;PRC&#39;);
use Monolog\Logger;
use Monolog\Handler\StdoutHandler;
// Create the logger
$logger = new Logger(&#39;my_logger&#39;);
// 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('0.9.0.1');
$config->setTopics(array('test'));
//$config->setOffsetReset('earliest');
$consumer = new \Kafka\Consumer();
$consumer->setLogger($logger);
$consumer->start(function($topic, $part, $message) {
	var_dump($message);
});
