With PHP it's possible to check if a cookie exists. Is there a similar way to check if a HTML5 sessionStorage (webstorage) item exists?

If you mean by sessionStorage the HTML5 web storage (as I understand from the tags in your question), then no. It is not possible to access this data from PHP. It can only be accessed with JavaScript and passed through to PHP with AJAX.
