Is there a way to clear egroupware's cache programmatically

I know we can clear egroupware’s cache from admin, but can it also be cleared programmatically

Why?

Sure, question is from what environment.

For an EGroupware app you can do what we do in our sources, when you call it in Admin:

github.com

EGroupware/egroupware/blob/master/admin/inc/class.admin_hooks.inc.php#L170




	/**
	 * Clears instance cache (and thereby also refreshes hooks)
	 */
	function ajax_clear_cache()
	{
		if ($GLOBALS['egw']->acl->check('applications_acc',16,'admin'))
		{
			$GLOBALS['egw']->redirect_link('/index.php');
		}
		Api\Cache::flush(Api\Cache::INSTANCE, !empty($_GET['errored']) ? "all" : null);


		Api\Image::invalidate();


		if (method_exists($GLOBALS['egw'],'invalidate_session_cache'))	// Egw object in setup is limited
		{
			$GLOBALS['egw']->invalidate_session_cache();	// in case with cache the egw_info array in the session
		}
		// allow apps to hook into "Admin >> Clear cache and register hooks"
		Api\Hooks::process('clear_cache', array(), true);
	}

From a shell script you can send a signal to the FPM process:

[docker exec -it egroupware] kill -s usr2 1

Hi Ralf

I’d like to do it from a custom application in egroupware
