README
kafka-php allows you to produce messages to the Apache Kafka distributed publish/subscribe messaging service.
Requirements
- Minimum PHP version: 5.3.3.
- Apache Kafka 0.6.x or 0.7.x.
- You need to have access to your Kafka instance and be able to connect through TCP. You can obtain a copy and instructions on how to setup kafka at https://github.com/kafka-dev/kafka
- The PHP Zookeeper extension is required if you want to use the Zookeeper-based consumer.
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).
Usage
The examples directory contains an example of a Producer and a simple Consumer, and an example of the Zookeeper-based Consumer.
Example Producer:
$producer = new Kafka_Producer('localhost', 9092, Kafka_Encoder::COMPRESSION_NONE);
$messages = array('some', 'messages', 'here');
$topic = 'test';
$bytes = $producer->send($messages, $topic);
Example Consumer:
$topic = 'test';
$partition = 0;
$offset = 0;
$maxSize = 1000000;
$socketTimeout = 5;
while (true) {
$consumer = new Kafka_SimpleConsumer('localhost', 9092, $socketTimeout, $maxSize);
$fetchRequest = new Kafka_FetchRequest($topic, $partition, $offset, $maxSize);
$messages = $consumer->fetch($fetchRequest);
foreach ($messages as $msg) {
echo "\nMessage: " . $msg->payload();
}
//advance the offset after consuming each MessageSet
$offset += $messages->validBytes();
unset($fetchRequest);
}
TODO
- support for Snappy compression
