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

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

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


  1. Add it to your composer.json:

        "require": {
            "sixdays/opcache-bundle": "dev-master"


        composer require sixdays/opcache-bundle
        composer update sixdays/opcache-bundle
  2. Add this bundle to your application kernel:

     // app/AppKernel.php
     public function registerBundles()
         return array(
             // ...
             new Sixdays\OpcacheBundle\SixdaysOpcacheBundle(),
             // ...
  3. Configure sixdays_opcache service:

     # app/config/config.yml
         base_url:   http://localhost/ #could also be https://, or, or any other valid URL
         web_dir:    %kernel.root_dir%/../web


Clear all opcache cache:

      $ php app/console opcache:clear

Capifony usage

To automatically clear opcache cache after each capifony deploy you can define a custom task

namespace :symfony do
  desc "Clear opcache cache"
  task :clear_opcache do
    capifony_pretty_print "--> Clear opcache cache"
    run "#{try_sudo} sh -c 'cd #{latest_release} && #{php_bin} #{symfony_console} opcache:clear --env=#{symfony_env_prod}'"

and add this hook

# opcache
after "deploy", "symfony:clear_opcache"

Nginx configuration

If you are using nginx and limiting PHP scripts that you are passing to fpm you need to allow 'opcache' 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 opcache cache.

Example configuration:

# Your virtual host
server {
  location ~ ^/(app|app_dev|opcache-.*)\.php(/|$) { { # This will allow opcache (opcache-{MD5HASH}.php) files to be processed by fpm
    fastcgi_pass      ;
