[](#installation)

1. Install [librdkafka c library](https://github.com/edenhill/librdkafka)

    ```
    $ cd /tmp
    $ mkdir librdkafka
    $ cd librdkafka
    $ git clone https://github.com/edenhill/librdkafka.git .
    $ ./configure
    $ make
    $ make install
    ```
2. Install the [php-rdkafka](https://github.com/arnaud-lb/php-rdkafka) PECL extension

    $ pecl install rdkafka
    ```
3. Add the following to your php.ini file to enable the php-rdkafka extension `extension=rdkafka.so`
4. `composer require superbalist/php-pubsub-kafka`

Usage
-----

[](#usage)

```
// create consumer
$topicConf = new \RdKafka\TopicConf();
$topicConf->set('auto.offset.reset', 'largest');

$conf = new \RdKafka\Conf();
$conf->set('group.id', 'php-pubsub');
$conf->set('metadata.broker.list', '127.0.0.1');
$conf->set('enable.auto.commit', 'false');
$conf->set('offset.store.method', 'broker');
$conf->set('socket.blocking.max.ms', 50);
$conf->setDefaultTopicConf($topicConf);

$consumer = new \RdKafka\KafkaConsumer($conf);

// create producer
$conf = new \RdKafka\Conf();
$conf->set('socket.blocking.max.ms', 50);
$conf->set('queue.buffering.max.ms', 20);

$producer = new \RdKafka\Producer($conf);
$producer->addBrokers('127.0.0.1');

$adapter = new \Superbalist\PubSub\Kafka\KafkaPubSubAdapter($producer, $consumer);

// consume messages
// note: this is a blocking call
$adapter->subscribe('my_channel', function ($message) {
    var_dump($message);
});

// publish messages
$adapter->publish('my_channel', 'HELLO WORLD');
$adapter->publish('my_channel', ['hello' => 'world']);
$adapter->publish('my_channel', 1);
$adapter->publish('my_channel', false);

// publish multiple messages
$messages = [
    ['hello' => 'world'],
    'lorem ipsum',
];
$adapter->publishBatch('my_channel', $messages);
```

Examples
--------

[](#examples)

The library comes with [examples](examples) for the adapter and a [Dockerfile](Dockerfile) for running the example scripts.

Run `make up`.

You will start at a `bash` prompt in the `/opt/php-pubsub` directory.

If you need another shell to publish a message to a blocking consumer, you can run `make shell`

To run the examples:

```
$ php examples/KafkaConsumerExample.php
$ php examples/KafkaPublishExample.php (in a separate shell)
```
