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

Posted in Tutorial PHP, Zend Framework 2 by samsonasik on October 6, 2013

zf2-zendframework2Zend 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',
                'lifetime' => 7200,
                'options'  => array(
                    '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 :).

    Hi
    thanks you very match .

    I want to use caches to optimize Zend/Mvc/Application::init because it take > 0,5 s

    is it possible ?

    i am using skeleton app.

    thankx.

    • samsonasik said, on October 6, 2013 at 10:37 pm

      i have no idea, sorry

      • AbderrahimDz24 said, on October 7, 2013 at 3:58 am

        thanks

        i tested it and it gives better response time ~ 0.6 s.
        is it (time) normal ? is there another way to get it better?

        thank you very match.

      • samsonasik said, on October 7, 2013 at 11:25 am

        i think normal or not it depend on your server spec, traffic, and configuration

      • AbderrahimDz24 said, on October 7, 2013 at 4:58 pm

        I using xampp 1.8.1 as server.

        I am the only one who send request.

        and i am using
        zfc-user module with bjy-authorize
        + MyModule

      • samsonasik said, on October 7, 2013 at 5:34 pm

        that strange, maybe you load huge resource/data. I have no idea for it.

      • AbderrahimDz24 said, on October 7, 2013 at 7:47 pm

        thank you.
        I’ll check it.

    • Fk said, on March 8, 2014 at 6:39 am

      Having the same behavior without any big data sets as well on really simple pages without any db connects. I’m going to debug what is causing this.

      Strangest thing until now: languages with po files, cache on file system is slower as no caching, cache on memcache is slower as file system and without cache. Tested in a productive environment on two servers, 250 measurements each, with two content locations. Any ideas?

      The test case (default language) to verification the test had in all 3 versions, like expected the same result/timing.

    • mockie said, on May 10, 2014 at 7:40 pm

      i’ve just found out about this case.. anyone who feels the same thing.. please check your memcached in you phpinfo() and make sure it does exist.. i felt this after installing memcached i only restart nginx but you need to restart php5-fpm too for php.ini changes.

  2. zack said, on October 7, 2013 at 8:45 am

    I’m sorry, but what is “11211” next to ip address? Thanks.

    • samsonasik said, on October 7, 2013 at 10:07 am

      port. read phpmanual!

    • Pedro J. said, on October 24, 2013 at 3:02 pm

      Hi zack,
      hello, this is the port (TCP/UDP) where memcache listens.

      br,
      Pedro J.

  3. Pedro J. said, on October 24, 2013 at 2:59 pm

    Hello Samsonasik,
    good information for Memcache, but if I use just as you describe I get the following error message:

    this call: $this->getServiceLocator()->get(‘memcached’);

    Additional information:
    Zend\ServiceManager\Exception\ServiceNotFoundException
    File:
    /var/www/app.com/vendor/zendframework/zendframework/library/Zend/ServiceManager/ServiceManager.php:495
    Message:
    Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for memcached

    So the error message but I have understood what I forgot?

    sorry for English
    Pedro J.

    • samsonasik said, on October 24, 2013 at 4:51 pm

      what zf version you’re using ? if it using ZF 2.2 , it should be worked.

  4. Pedro J. said, on October 24, 2013 at 10:51 pm

    Hi,
    my version is “zendframework/zendframework”: “2.2.*”

    Pedro J.

    • samsonasik said, on October 24, 2013 at 11:38 pm

      it must be your config not accessible, or you forgot register the abstract_factories.

  5. Pedro J. said, on October 25, 2013 at 4:00 am

    Hi samsonasik,
    the abstract class I have registered as they have written in tutorial.

      check if there is a file named Zend\Cache\Service\StorageCacheAbstractServiceFactory.php at your zf2 library.

  7. Pedro J. said, on October 25, 2013 at 1:40 pm

    Hi,
    yes, I have.

    • samsonasik said, on October 25, 2013 at 3:42 pm

      that’s strange. please do :

      \Zend\Debug\Debug::dump($this->getServiceLocator()->get('Config'));
      

      and find if ‘memcached’ is under ‘caches’ array.

      • Pedro J. said, on October 25, 2013 at 4:04 pm

        Hi,
        Yes I have, but why is not loaded? do you have any idea what is problem?

        ["caches"] => array(1) {
        ["memcached"] => array(2) {
        ["adapter"] => array(3) {
        ["name"] => string(9) “memcached”
        ["lifetime"] => int(7200)
        ["options"] => array(3) {
        ["servers"] => array(1) {
        [0] => array(2) {
        [0] => string(9) “127.0.0.1”
        [1] => int(11211)
        }
        }
        ["namespace"] => string(20) “MYMEMCACHEDNAMESPACE”
        ["liboptions"] => array(4) {
        ["COMPRESSION"] => bool(true)
        ["binary_protocol"] => bool(true)
        ["no_block"] => bool(true)
        ["connect_timeout"] => int(100)
        }
        }
        }
        ["plugins"] => array(1) {

        ["throw_exceptions"] => bool(false)
        }
        }
        }
        }

        memcached is installed and running with php exted.

      • samsonasik said, on October 25, 2013 at 4:16 pm

        I have no idea. Sorry. Maybe you need to create your own abstract_factories :)

      For all having trouble – there are 2 different php librarys called “memcache” and “memcached” doing nearly the same job. Seems to be a bit unlucky in the naming… If you having trouble check with phpinfo() if “memcached” is installed otherwise apt-get install php5-memcached

        my application did worked, i want use memcache to speeding application when query database, but it didn’t worked with “$ this-> getServiceLocator () -> get (‘memcached’) -> SetItem (‘foo’, ‘bar’); “

      • samsonasik said, on April 22, 2014 at 9:56 am

        based on your error, you don’t have “error” template, that’s not related with its cache part, that related with your skeleton, please do effor to find solution by looking the error.

    What type of object will return
    $this->getServiceLocator()->get(‘memcached’)

    ?

    \Memcached or some Zend implementation?

    • seyferx said, on May 20, 2014 at 4:18 pm

      Zend\Cache\Storage\Adapter\Memcach will returns

      I’m like factory way more, for example

      class CacheFactory() {

      $cache = new \Zend\Cache\Storage\Adapter\Filesystem();
      $cache->getOptions()
      ->setWritable(TRUE)
      ->setReadable(TRUE)
      ->setTtl(3600)
      ->setCacheDir(‘./data/cache/filesystem’)
      ->setDirPermission(“777″)->setFilePermission(‘666′);

      $plugin = new \Zend\Cache\Storage\Plugin\ExceptionHandler();
      $plugin->getOptions()->setThrowExceptions(false);
      $cache->addPlugin($plugin);
      $pluginSerializer = new \Zend\Cache\Storage\Plugin\Serializer();
      $cache->addPlugin($pluginSerializer);

      return $cache

      }

      and use it in config

    I have error :

    An abstract factory could not create an instance of memcached(alias: memcached).

    Please help me fix it

    • samsonasik said, on August 5, 2014 at 8:49 pm

      please take a look the full stack trace, it should be because you doens’t have memcached installed. please google for it.

      • Vu said, on August 24, 2014 at 7:54 pm

        when i use code below :

        connect(‘localhost’,11211);
        echo $memcache->getVersion();
        }
        else{
        die(‘Can not connect to Memcache Server’);
        }
        ?>

        Result is 1.2.6

        but when I use in zf2, I have an error as above,
        I do not know how to fix it, please help
