-### I must use PHP 5.4 or 5.5. What can I do?
-You won't be able to send any payload, so you'll only be able to use `sendOneNotification($subscription)` or `queueNotification($subscription)`.
-Install the library with `composer` using `--ignore-platform-reqs`.
-The workaround for getting the payload is to fetch it in the service worker ([example](https://github.com/Minishlink/physbook/blob/2ed8b9a8a217446c9747e9191a50d6312651125d/web/service-worker.js#L75)).
