Updatesīy default, PhpStorm is configured to check for updates automatically and notify you when a new version is available. Changes that are added to online help during the release cycle may not be available in the offline help. The offline help plugin is updated when a new major version is released. If you don't have internet access to view the online help, you can use the PhpStorm Help plugin, which serves the help pages via the built-in web server for offline use. If you are working offline (for example, in an isolated environment), there are some aspects that you should keep in mind. A lot of features in PhpStorm require access to the Internet.
