Using and Configuring Zend Session and Zend Cache Memcached - Zend Framework 2.3 - session

Question

Actually, I'm using "standard" sessions manager config:
http://framework.zend.com/manual/current/en/modules/zend.session.manager.html
I want to use cache and save my session's data into server's cache (memcached) for improves performances and scalability.
I set php.ini like this (localhost memcached):
session.save_handler=memcached
session.save_path= "tcp://127.0.0.1"
and it show this error:
Warning: session_start(): Cannot find save handler 'memcached' - session startup failed in C:\Program Files (x86)\xampp\htdocs\Zend-application\vendor\zendframework\zendframework\library\Zend\Session\SessionManager.php on line 98
So, I don't understand how to configure my config/autoload/global.php and module/application/module.php. it's my first time that I want to implement memcached and caching in general. thanks, so much!
I tried to modify module/application/module.php like this:
---add session and cache ---
use Zend\Session\Config\SessionConfig;
use Zend\Session\Container;
use Zend\Cache\StorageFactory;
use Zend\Session\SaveHandler\Cache;
use Zend\Session\SessionManager;
use Zend\Session\Validator\HttpUserAgent;
use Zend\Session\Validator\RemoteAddr;
--- end session and cache ---
public function onBootstrap($e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
$this->initSession(array(
'remember_me_seconds' => 180,
'use_cookies' => true,
'cookie_httponly' => true,
'validators' => array(
'Zend\Session\Validator\RemoteAddr',
'Zend\Session\Validator\HttpUserAgent',
'phpSaveHandler' => 'memcached',
'savePath' => 'tcp://127.0.0.1',
)
));
}
public function initSession($config)
{
$sessionConfig = new SessionConfig();
$sessionConfig->setOptions($config);
$sessionManager = new SessionManager($sessionConfig);
$sessionManager->getValidatorChain()
->attach(
'session.validate',
array(new HttpUserAgent(), 'isValid')
)
->attach(
'session.validate',
array(new RemoteAddr(), 'isValid')
);
$cache = StorageFactory::factory(array(
'adapter' => array(
'name' => 'memcached',
'options' => array(
'server' => '127.0.0.1',
),
)
));
$saveHandler = new Cache($cache);
$sessionManager->setSaveHandler($saveHandler);
$sessionManager->start();
Container::setDefaultManager($sessionManager);
}
but it shows this error:
Warning: ini_set() expects parameter 2 to be string, array given in C:\Program Files (x86)\xampp\htdocs\Zend-application\vendor\zendframework\zendframework\library\Zend\Session\Config\SessionConfig.php on line 88
Fatal error: Call to undefined method Zend\Stdlib\CallbackHandler::attach() in C:\Program Files (x86)\xampp\htdocs\Zend-application\module\Application\Module.php on line 68
this is my config/autoload/global.php
return array(
'db' => array(
'driver' => 'Pdo_Mysql',
'charset' => 'utf-8',
'dsn' => 'mysql:dbname=mydb;host=localhost',
'driver_options' => array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
),
),
'service_manager' => array(
'factories' => array(
'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
),
),
'session' => array(
'config' => array(
'class' => 'Zend\Session\Config\SessionConfig',
'options' => array(
'name' => 'zend-application',
),
),
'storage' => 'Zend\Session\Storage\SessionArrayStorage',
'validators' => array(
'Zend\Session\Validator\RemoteAddr',
'Zend\Session\Validator\HttpUserAgent',
),
),
);

Hoping it'll help someone, I resolved my issue. I'm working in Win7 enviroment and memcached doesn't work on it! I changed :
session.save_handler=memcached
session.save_path= "tcp://127.0.0.1"
to
session.save_handler=memcache
session.save_path= "tcp://127.0.0.1:11211"
I restored the "standard" session manager config and memcache works correctly. When I'll transfer the entire site to apache server, I'll change php.ini for using memcached.
