// Create a new batch queue plugin.  Any reqeust created by a client will be
// automatically tracked and queued by the BatchQueuePlugin.  You can specify
// the maximum amount of requests to keep in queue before implicitly flushing,
// or set 0 to never automatically flush.  Here we are saying that if 10 or
// more requests are in the batch queue, then it must automatically flush the
// queue and send the requests.
$batchPlugin = new BatchQueuePlugin(10);

// Create a mock plugin that will satisfy requests using mock responses
// Mock requests will be removed from the mock queue as requests are
// sent by an attached client
$mockPlugin = new MockPlugin(array(
    new Response(200),
    new Response(201),

// Add the batch plugin to the client object
$client->getEventDispatcher()->addSubscriber($batchPlugin);
// Add the mock plugin to the client object so that requests are mocked
$client->getEventDispatcher()->addSubscriber($mockPlugin);

// Queue up some requests on the BatchQueuePlugin
$request1 = $client->get('/');
$request2 = $client->get('/');
$request3 = $client->get('/');

// If the batch plugin is handy, you can call the flush method directly
$batchPlugin->flush();

// If you no longer have the batch plugin handy, you can emit the 'flush' event
// from the client
$client->dispatch('flush');

// Now the requests have been sent and have been served a mock response
