Set memcache in PHP

Install Memcache 
aptitude install memcached
aptitude install php5-memcache


Check install memcache
php -m | grep memcache


Check memcache is run
$ ps -aux | grep memcached

Add this function in bootstrap

protected function _initCache()

        if (isset($options['cache'])) {
            $cache = Zend_Cache::factory(
                $options['cache']['frontend']['type'],

                $options['cache']['frontend']['options'],
                $options['cache']['backend']['options']
            );


            Zend_Registry::set('cache', $cache);
            return $cache;
        }
}

Or set memcache

resources.session.saveHandler.class = "App_Session_SaveHandler_Cache"
resources.session.saveHandler.options.type = "Libmemcached"
resources.session.saveHandler.options.maxlifetime = 300
resources.session.saveHandler.options.front.lifetime = 300
resources.session.saveHandler.options.front.automatic_serialization = true
resources.session.saveHandler.options.back.servers.0.host = "127.0.0.1"
resources.session.saveHandler.options.back.servers.0.port = 11211
resources.session.saveHandler.options.back.servers.0.persistent = true
resources.session.saveHandler.options.back.servers.0.status = true
resources.session.saveHandler.options.back.servers.1.host = "127.0.0.2"
resources.session.saveHandler.options.back.servers.1.port = 11211
resources.session.saveHandler.options.back.servers.1.persistent = true
resources.session.saveHandler.options.back.servers.1.status = true

The session save handler class (App_Session_SaveHanlder_Cache implements Zend_Session_SaveHandler_Interface and uses Zend_Cache factory passing in the Libmemcached option for the backend storage.

In my bootstrap, I have an _init method listed as the first method which calls the session bootstrap:

protected function _initForceSession()
{   
    $this->bootstrap('session');
    Zend_Session::start();
}

Use cache in webservice

$cache = Zend_Registry::get('cache');
$cache->setLifetime(86400);


$client = new Client();
$client->setCache($cache);
