Provide a command to clear APC cache from CLI

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

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

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

Prerequisite

If you want to clear Apache part of APC, you will need to enable allow_url_fopen in php.ini to allow opening of URL object-like files, or set the curl option.

Installation

1. Add this bundle to your project as a Git submodule:

    $ git submodule add git://github.com/ornicar/ApcBundle.git vendor/Bundles/Ornicar/ApcBundle
   

2. Add Ornicar namespace to your autoloader:

    // app/autoload.php
    $loader->registerNamespaces(array(
       'Ornicar' => __DIR__.'/../vendor/bundles',
       // your other namespaces
    );
   

3. Add this bundle to your application kernel:

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

4. Configure ornicar_apc service:

    # app/config/config.yml
    ornicar_apc:
        host: http://example.com
        web_dir: %kernel.root_dir%/../web
   

5. (Optional) If you want to use curl rather than fopen set the following option:

    # app/config/config.yml
    ornicar_apc:
        ...
        mode: curl
   

6. (Optional) You may also change the owner and file permissions of the temporary file that is written to the web directory. Here's the default configuration:

    # app/config/config.yml
    ornicar_apc:
        ...
        set_permissions:  false   # set this to true if you want the file mode and owner to be changed
        file_mode:    755         # default value
        web_user:     www-data    # default value
   

Usage

Clear all APC cache (opcode+user):

      $ php app/console apc:clear

Clear only opcode cache:

      $ php app/console apc:clear --opcode

Clear only user cache:

      $ php app/console apc:clear --user
