# React/ZMQ

ZeroMQ bindings for React.

[![Build Status](https://secure.travis-ci.org/friends-of-reactphp/zmq.png?branch=master)](http://travis-ci.org/friends-of-reactphp/zmq)

## Install

The recommended way to install react/zmq is [through composer](http://getcomposer.org).

```bash
composer require react/zmq
```

## Example

And don't forget to autoload:

```php
<?php
require 'vendor/autoload.php';
```

Here is an example of a push socket:

```php
<?php

$loop = React\EventLoop\Factory::create();

$context = new React\ZMQ\Context($loop);

$push = $context->getSocket(ZMQ::SOCKET_PUSH);
$push->connect('tcp://127.0.0.1:5555');

$i = 0;
$loop->addPeriodicTimer(1, function () use (&$i, $push) {
    $i++;
    echo "sending $i\n";
    $push->send($i);
});

$loop->run();
```

And the pull socket that goes with it:

```php
<?php

$loop = React\EventLoop\Factory::create();

$context = new React\ZMQ\Context($loop);

$pull = $context->getSocket(ZMQ::SOCKET_PULL);
$pull->bind('tcp://127.0.0.1:5555');

$pull->on('error', function ($e) {
    var_dump($e->getMessage());
});

$pull->on('message', function ($msg) {
    echo "Received: $msg\n";
});

$loop->run();
```

## Todo

* Integration tests
* Buffer limiting
* Do not push messages if no listener

## Tests

To run the test suite, you need PHPUnit.

    $ phpunit
