Installation

• Install the plugin

  $ symfony plugin:install zendCachePlugin
  

• Enable the plugin in your ProjectConfiguration class

  # in file SF_ROOT_DIR/config/Projectconfiguration.class.php
  
  class ProjectConfiguration extends sfProjectConfiguration
  {
    public function setup()
    {
      /* ... */
  
      $this->enablePlugins( 'zendCachePlugin' );
  
      /* ... */
    }
  }
  

• Clear the cache

  $ symfony cc
  

Usage

View and partial caching

To use Zend Data cache for caching your views and partials, update apps/my_app/config/factories.yml :

all: view_cache: class: zendShmCache # or "zendDiskCache" param: automaticCleaningFactor: 0

Clear cache and you are done !

$ symfony cc

Use it in scripts

There is nothing more in it than in the sfCache API:

<?php

// instanciate a $cache object
$cache = new zendShmCache();

// Storing data in cache
$cache->set( 'a key', $my_data, $user_defined_lifetime );

// Checking if some data is available in cache
if ( $cache->has('some data') )
{
  // It's here ! let's retrieve it
  $data = $cache->get('some data');
}
else
{
  // Do not exists or to late (timed out...)
}

// removing some data
$cache->remove( 'some data');

// cleaning the full cache
$cache->clean();

?>

Using namespaces

Namespaces use the prefix option:

<?php

// instanciate to cache objects with different namespaces
$cache_DE = new zendShmCache( array( 'prefix' => 'de' ) );
$cache_FR = new zendShmCache( array( 'prefix' => 'en' ) );

// store datas
$cache_DE->set( 'hello', 'Guten Tag' );
$cache_FR->set( 'hello', 'Bonjour' );

// and retrieve them
echo $cache_DE->get( 'hello' ); // 'Guten Tag';
echo $cache_FR->get( 'hello' ); // 'Bonjour';

?>

TODO

• Checking if prefix options is well formed (zend_cache_info is not allowed !!!, avoid :: in prefix name)
• Using an alternate namespace option
