Hoa is a modular, extensible and structured set of PHP libraries. Moreover, Hoa aims at being a bridge between industrial and research worlds.

This library allows to create shared workers in order to lift out some heavy and blocking tasks.

With Composer, to include this library into your dependencies, you need to require hoa/worker:

{
    "require": {
        "hoa/worker": "~2.0"
    }
}

Please, read the website to get more informations about how to install.

As a quick overview, we see how to create a worker and how to communicate with it.

First, we need to register the worker (i.e. creating a .wid file), called demorker:

if (false === Hoa\Worker\Run::widExists('demorker')) {
    Hoa\Worker\Run::register('demorker', 'tcp://127.0.0.1:123456');
}

Then, we start the worker (with a password) and we listen to messages:

$worker = new Hoa\Worker\Backend\Shared('demorker', 'iamapassword');
$worker->on('message', function(Hoa\Core\Event\Bucket $bucket) {
    $data = $bucket->getData();
    // compute $data['message'].
});
$worker->run();

The message indicates a task to do (sending an email, create some archives, update the database, send some notifications…).

We are also able to manage all workers from a CLI.

Second, since the worker is running, we can communicate with it from our application. Thus:

$worker = new Hoa\Worker\Shared('demorker');
$worker->postMessage('mail gordon@freeman.hl Hello Gordon!');

We are able to send everything that can be serialized.
