composer require rackspace/php-opencloud

require 'vendor/autoload.php';

$client = new OpenCloud\OpenStack('{keystoneUrl}', array(
  'username' => '{username}',
  'password' => '{apiKey}',
  'tenantId' => '{tenantId}',
));

$service = $client->objectStoreService('{catalogName}', '{region}', '{urlType}');

foreach ($containers as $container) {
    /** @param $container OpenCloud\ObjectStore\Resource\Container */
    printf("Container name: %s\n", $container->name);
    printf("Number of objects within container: %d\n", $container->getObjectCount());
}

$containers = $service->listContainers();
** @param $container OpenCloud\ObjectStore\Resource\Container */
$container = $service->getContainer('{containerName}');
