What is the best way to clean the cache without running the console command?

You can use the console command via exec():

exec("php /my/project/app/console cache:clear --env=prod");

Or simply empty the cache/ folder if you don't want to use the console command.

You can call this action to clear a cache:

/** * @Route("/cache/clear", name="adyax_cache_clear") */  public function cacheClearAction(Request $request) {    $input = new \Symfony\Component\Console\Input\ArgvInput(array('console','cache:clear'));    $application = new \Symfony\Bundle\FrameworkBundle\Console\Application($this->get('kernel'));    $application->run($input);   }

Most recent best way (2017). I'm creating this in controller:

use Symfony\Component\Console\Input\ArrayInput;use Symfony\Bundle\FrameworkBundle\Console\Application;use Symfony\Component\Console\Output\BufferedOutput;/** * Refresh Cache */public function refreshRoutes(){    $kernel = $this->container->get('kernel');    $application = new Application($kernel);    $application->setAutoExit(false);    $input = new ArrayInput([        'command' => 'cache:clear',        '--env'   => 'prod',    ]);    $output = new BufferedOutput();    $application->run($input, $output);}
