Provide a command line to clear APC/APCu cache from the console.

The problem with APC/APCu is that it's impossible to clear it from command line. Because even if you enable APC/APCu for PHP CLI, it's a different instance than, say, your Apache PHP or PHP-CGI APC/APCu instance.

The trick here is to create a file in the web dir, execute it through HTTP, then remove it.

Installation

1. Add it to your composer.json:

   {
       "require": {
           "symbio/apc-bundle": "dev-master"
       }
   }

   or:

       composer require symbio/apc-bundle:dev-master
       composer update symbio/apc-bundle:dev-master

2. Add this bundle to your application kernel:

    // app/AppKernel.php
    public function registerBundles()
    {
        return array(
            // ...
            new Symbio\ApcBundle\SymbioApcBundle(),
            // ...
        );
    }
   

3. Add parameter with website URL:

    # app/config/parameters.yml, app/config/parameters.yml.dist
    cache.base_url: https://your.website.url
   

4. Configure symbio_apc service:

    # app/config/config.yml
    symbio_apc:
        base_url:   %cache.base_url%/
        web_dir:    %kernel.root_dir%/../web
   

5. Set Apache user write permissions to web_dir

    $ chmod 775 web
   

Usage

Clear all APC/APCu cache:

  $ php app/console symbio:apc:clear
  $ php app/console symbio:apcu:clear

Capifony usage

To automatically clear APC/APCu cache after each capifony deploy you can define a custom task

namespace :symfony do
  desc "Clear APC/APCu cache"
  task :clear_apc do
    capifony_pretty_print "--> Clear APC cache"
    run "#{try_sudo} sh -c 'cd #{latest_release} && #{php_bin} #{symfony_console} symbio:apc:clear --env=#{symfony_env_prod}'"
    capifony_puts_ok
  end
end

and add this hook

# apc
after "deploy", "symfony:clear_apc"

Nginx configuration

If you are using nginx and limiting PHP scripts that you are passing to fpm you need to allow 'APC/APCu' prefixed php files. Otherwise your web server will return the requested PHP file as text and the system won't be able to clear the APC/APCu cache.

Example configuration:

# Your virtual host
server {
  ...
  location ~ ^/(app|app_dev|apcu?-.*)\.php(/|$) { { # This will allow APC/APCu (apc-{MD5HASH}.php) files to be processed by fpm
    fastcgi_pass                127.0.0.1:9000;
    ...
