My bet is that your host is blocking incoming requests to the socket. Your not supposed to run scripts like phpwebsocket within a web service (it is a server itself). This confuses a lot of people since PHP is typically used for scripting webpages, not for coding daemons.
I say this because you mentioned running the script within Xampp, and referred to your hosting service as 'webspace'.
If this is the case you will have to upgrade to a virtual server package so that you can run your own services.
