How to invalidate container cache in Symfony2?

Question

Part of my Symfony app configuration is being loaded from legacy database, so sometimes I need to invalidate container cache to make use of updated data.

Is there any API to invalidate Symfony container cache programmatically?

Answer 1

1. As per CacheClearCommand :

    $filesystem = $this->container->get('filesystem'); $realCacheDir = $this->container->getParameter('kernel.cache_dir'); $this->container->get('cache_clearer')->clear($realCacheDir); $filesystem->remove($realCacheDir); 

2. Directly call CacheClearCommand from code:

   services.yml

    clear_cache_command_service: class: Symfony\\Bundle\\FrameworkBundle\\Command\\CacheClearCommand calls: - [setContainer, ["@service_container"] ] 

   Than it's possible to do something like this (note that this will warmup the cache):

    $clearCacheCommand = $this->container->get('clear_cache_command_service'); $clearCacheCommand->run(new ArgvInput(), new ConsoleOutput());
