First, configure your cache providers under the doctrine_cache configuration
option. Example:
doctrine_cache: providers: my_apc_metadata_cache: type: apc namespace: metadata_cache_ns my_apc_query_cache: namespace: query_cache_ns apc: ~
<?xml version="1.0" encoding="UTF-8" ?><container xmlns="http://symfony.com/schema/dic/services" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:doctrine-cache="http://doctrine-project.org/schemas/symfony-dic/cache" xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd http://doctrine-project.org/schemas/symfony-dic/cache http://doctrine-project.org/schemas/symfony-dic/cache/doctrine_cache-1.0.xsd"> <doctrine-cache:doctrine-cache> <doctrine-cache:provider name="my_apc_metadata_cache"> <doctrine-cache:type>apc</doctrine-cache:type> <doctrine-cache:namespace>metadata_cache_ns</doctrine-cache:namespace> </doctrine-cache:provider> <doctrine-cache:provider name="my_apc_query_cache" namespace="query_cache_ns"> <doctrine-cache:apc/> <doctrine-cache:provider> </doctrine-cache:doctrine-cache></container>
Then, use the newly created doctrine_cache.providers.{provider_name} container
services anywhere in your application:
$metadataCache = $this->container->get('doctrine_cache.providers.my_apc_metadata_cache');
$queryCache = $this->container->get('doctrine_cache.providers.my_apc_query_cache');
In order to make your code more concise, you can define aliases for these services
thanks to the aliases configuration option. Example:
doctrine_cache: aliases: apc_cache: my_apc_cache providers: my_apc_cache: type: apc namespace: my_apc_cache_ns aliases: - apc_cache
<?xml version="1.0" encoding="UTF-8" ?><dic:container xmlns="http://doctrine-project.org/schemas/symfony-dic/cache" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:srv="http://symfony.com/schema/dic/services" xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd http://doctrine-project.org/schemas/symfony-dic/cache http://doctrine-project.org/schemas/symfony-dic/cache/doctrine_cache-1.0.xsd"><srv:container> <doctrine-cache> <alias key="apc_cache">my_apc_cache</alias> <provider name="my_apc_cache"> <type>apc</type> <namespace>my_apc_cache_ns</namespace> <alias>apc_cache</alias> </provider> </doctrine-cache></srv:container>
Now you can use the short apc_cache alias to get the provider called
my_apc_cache, instead of using doctrine_cache.providers.my_apc_cache:
$apcCache = $this->container->get('apc_cache');
