Zend Framework 2 : using ‘caches’ configuration to setting up cache services

Zend Framework 2.2 has Zend\Cache\Service\StorageCacheAbstractServiceFactory that allow us to configure cache services via array configuration. We just need to register the abstract factory and create a config array that represent cache options. I will give you an example if we want to create memcached service.

1. register to service manager

   //config/autoload/global.php
   'service_manager' => array(
        'abstract_factories' => array(
               'Zend\Cache\Service\StorageCacheAbstractServiceFactory',
         )
   ),
   

2. configure array cache options, for example, I write at config/autoload/cache.local.php

   //config/autoload/cache.local.php
   <?php
   
   return array(
       'caches' => array(
           'memcached' => array( //can be called directly via SM in the name of 'memcached'
               'adapter' => array(
                   'name'     =>'memcached',
                   'options'  => array(
                       'ttl' => 7200, 
                       'servers'   => array(
                           array(
                               '127.0.0.1',11211
                           )
                       ),
                       'namespace'  => 'MYMEMCACHEDNAMESPACE',
                       'liboptions' => array (
                           'COMPRESSION' => true,
                           'binary_protocol' => true,
                           'no_block' => true,
                           'connect_timeout' => 100
                       )
                   )
               ),
               'plugins' => array(
                   'exception_handler' => array(
                       'throw_exceptions' => false
                   ),
               ),
           ),
       ),
   );
   

   Done, and we can call

   $this->getServiceLocator()->get('memcached'); 
   

   from service that implements ServiceLocatorAwareInterface ( controllers or other service(s)).

Want to check ? Check this at your controller :

//filling cache value
public function indexAction()
{
      $this->getServiceLocator()->get('memcached')->setItem('foo', 'bar');
}
//retrieve cache value
public function retrieveAction()
{
    echo $this->getServiceLocator()->get('memcached')->getItem('foo');
}

If you want to set multi-cache config, just configure, and call them :).
