How to use replayId from Streaming API about salesforce-rest-sdk

[curiosity26]

The Bayuex client takes care of it all for you. You only need to create the client, add the extensions you want, subscribe a consumer to a channel and then start the client.

Here's a quick example:

<?php

$streamingClient = new BayeuxClient(
            new LongPollingTransport(),
            new OAuthProvider(
                getenv("SF_CLIENT_ID"),
                getenv("SF_CLIENT_SECRET"),
                getenv("SF_LOGIN_URL"),
                getenv("SF_USER"),
                getenv("SF_PASS")
            )
        );

$streamingClient->addExtension(new ReplayExtension(ReplayExtension::REPLAY_SAVED));

// Creates a new channel with the client if one does not exist already
$channel = $streamingClient->getChannel('/topic/Accounts');
// Subscribe a consumer to the channel
$channel->subscribe(
       Consumer::create(
            function (ChannelInterface $channel, Message $message) {
                $data = $message->getData();
                $sobject = $data->getSobject();

                // Do something with the object

                $replayId = $data->getEvent()->getReplayId();
            }
      )
);

// When you start the client, all defined channels make a subscribe call to Salesforce after the handshake
// When the channel receives a message from Salesforce, all consumers that have subscribed
// to the channel are fired in order of their priority
// This will run forever or until you stop it
$streamingClient->start();

I have a similar question. If I want to manually specify the Replay ID, I seem to not able to do this. Can you advise? I assumed $channel->addExtension(new ReplayExtension(<REPLAY_ID_HERE>)); would work.
