README

Below you can find a tutorial and usage example. For more information please refer to MigratoryData Documentation 5.x. MigratoryData Documentation 6.x.

Usage

Install the MigratoryData client library 5.x using composer (MigratoryData client version 5 can be used with MigratoryData Server 5.0.*):

$ composer require migratorydata/migratorydata-client-reactphp:5.*

Install the MigratoryData client library 6.x using composer (MigratoryData client version 6 can be used with the MigratoryData server 6.0.1 or later and the MigratoryData KE server 6.0.1 or later):

$ composer require migratorydata/migratorydata-client-reactphp:6.*

Import classes and define MigratoryData callback listener:

require __DIR__ . '/vendor/autoload.php';

use MigratoryData\Client\MigratoryDataClient;
use MigratoryData\Client\MigratoryDataMessage;
use MigratoryData\Client\MigratoryDataListener;

class MyListener implements MigratoryDataListener
{
    public function onMessage($message)
    {
        echo "Got message: " . $message . "\n";
    }

    public function onStatus($status, $info)
    {
        echo "Got status: " . $status . " - " . $info . "\n";
    }
}

Create the event loop:

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

Create a MigratoryData client and attach the event loop:

$client = new MigratoryDataClient(); 
$client->setLoop($loop);

Initialize and connect the MigratoryData client:

$client->setEntitlementToken("some-token");
$client->setServers(array("http://127.0.0.1:8800"));

$client->subscribe(array("/server/status"));

$client->connect();

Publish a message every second to MigratoryData server:

$loop->addPeriodicTimer(1, function () use ($client) {
    try {
        $client->publish(new MigratoryDataMessage("/server/status", "Msg " . time(), "closure-" . time()));
    } catch (MigratoryDataException $e) {
        echo($e->getDetail());
        echo($e->getCause());
    }
});

Start the event loop:

$loop->run();

Example client application

Copy the code below to a file named echo-time-client.php and run it using the following command:

$ php echo-time-client.php

Example for PHP React Client API The client application connects to the MigratoryData server deployed at localhost:8800 subscribes and publishes a message every second on the subject /server/status.

<?php

require __DIR__ . '/vendor/autoload.php';

use MigratoryData\Client\MigratoryDataClient;
use MigratoryData\Client\MigratoryDataException;
use MigratoryData\Client\MigratoryDataMessage;
use MigratoryData\Client\MigratoryDataListener;

class MyListener implements MigratoryDataListener
{
    public function onMessage($message)
    {
        echo "Got message: " . $message . "\n";
    }

    public function onStatus($status, $info)
    {
        echo "Got status: " . $status . " - " . $info . "\n";
    }
}

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

$client = new MigratoryDataClient();
$client->setEntitlementToken("some-token");
$client->setLoop($loop);
$client->setListener(new MyListener());

try {
    $client->setServers(array("http://127.0.0.1:8800"));
} catch (MigratoryDataException $e) {
    echo($e->getDetail());
    exit(1);
}

$client->subscribe(array("/server/status"));

$client->connect();

$loop->addPeriodicTimer(1, function () use ($client) {
    try {
        $client->publish(new MigratoryDataMessage("/server/status", "Msg " . time(), "closure-" . time()));
    } catch (MigratoryDataException $e) {
        echo($e->getDetail());
        echo($e->getCause());
    }
});


$loop->run();
