The following code connects to Ably's REST messaging service, gets reference to a channel to receive messages, and publishes a test message to that same channel:

// Initialize Ably REST client
$ably = new AblyRest(['key' => 'your-ably-api-key', 'clientId' => 'me']);

// Get a reference to the 'test-channel' channel
$channel = $ably->channel('test-channel');

// Publish a test message to the channel
$channel->publish('test-event', 'hello world');
