Creating a Worker

TL;DR

Definitions

A worker is the process that runs the actions. It has three components:

One or more Actions (the functions that you want to execute).
A Service (which contains the Actions. It runs as a sub-process from the Worker.)
The Worker (which communicates with the AlphaRPC Worker Handler).

Create your first worker!

The following code is all there is to it:

use AlphaRPC\Worker\Runner as WorkerRunner;
use AlphaRPC\Worker\Service;

$worker = new WorkerRunner(
    'tcp://127.0.0.1:61003', // Worker Handler address
    './ipc'                  // Writable directory for IPC files.
);

$worker->forkAndRunService(function (Service $service) {
    $service->addAction(
        // Name of the Action.
        'reverse',

        // Implementation of the Action.
        function($param) { return strrev($param); }
    );
});

$worker->run();

Run the worker

To run the worker:

php worker.php

Using the Action

Now you can use the client to perform the Action. See Using the Client.
