// This is a basic example on how to use the Predis\MonitorContext class.
// You can use redis-cli to send commands to the same Redis instance your client is
// connected to, and then type "ECHO QUIT_MONITOR" in redis-cli when you want to
// exit the monitor loop and terminate this script in a graceful way.

// Create a client and disable r/w timeout on the socket.
$client = new Predis\Client($single_server + array('read_write_timeout' => 0));

// Use only one instance of DateTime, we will update the timestamp later.
$timestamp = new DateTime();

foreach (($monitor = $client->monitor()) as $event) {
    $timestamp->setTimestamp((int) $event->timestamp);

// If we notice a ECHO command with the message QUIT_MONITOR, we close the
    // monitor context and then break the loop.
    if ($event->command === 'ECHO' && $event->arguments === '"QUIT_MONITOR"') {
        echo "Exiting the monitor loop...\n";
        $monitor->closeContext();
        break;
    }

echo "* Received {$event->command} on DB {$event->database} at {$timestamp->format(DateTime::W3C)}\n";
    if (isset($event->arguments)) {
        echo "    Arguments: {$event->arguments}\n";
    }
}

// Say goodbye :-)
$info = $client->info();
print_r("Goodbye from Redis v{$info['redis_version']}!\n");
