php - ZF2 Redis: how to set expiration time for a key -

i have set redis on server store information zend framework 2. now, can store information, can not give them expiration time naturally renew after while.

i have not found documentations step , seems me rather obscure.

my code:

page: config/autoload/cache.global.php

return array(     'caches' => array(         'redis' => array (             'adapter' => array (                 'name' => 'redis',                 'lifetime' => 60, //doesn't work                 'options' => array (                     'server' => array (                         'host' => 'x.x.x.x',                         'port' => x                     ),                     'ttl' => 10, // seems have no effect                     'namespace' => 'mycache',                 ),             ),         )     ) ); 

in controller :

.. use zend\cache\storagefactory; ..         $redis = storagefactory::factory ($this->getservicelocator ()              ->get ('config')['caches']['redis']);          if ($redis->hasitem ('test')) {                 var_dump($redis->getitem ('test'));                 $redis->removeitem('test');         } else {             $redis->additem('test', 'testtest');         } .. 

i tried several methods, everytime, result same, no expiration information appears in redis :

127.0.0.1:6379> mycache:test "testtest" 127.0.0.1:6379> ttl mycache:test (integer) -1 

thanks help!

take @ redis factory bellow:

 <?php  namespace application\service\factory;   use zend\servicemanager\factoryinterface;  use zend\servicemanager\servicelocatorinterface;  use zend\cache\storage\adapter\redisoptions;  use zend\cache\storage\adapter\redis;   class rediscachefactory implements factoryinterface  {      public function createservice(servicelocatorinterface $servicelocator)     {         $config = $servicelocator->get('config');         $config = $config['redis'];          $options = new redisoptions();         $options->setserver(             [                 'host' => $config["host"],                 'port' => $config["port"],                 'timeout' => $config["timeout"]             ]         );         $options->setttl(60);          /**          * not required, although allow store can serialized php in redis          */         $options->setliboptions(             [                 \redis::opt_serializer => \redis::serializer_php             ]          );          $redis = new redis($options);          return $redis;     } } 

as can see example, ttl set 60 seconds , working expected.
