This project provides the functionality of an RFC-6455 (or Version 13) WebSockets server. It can be used as a stand-alone server, or as the back-end of a normal HTTP server that is WebSockets aware. In order to use PHP WebSockets, you must have the ability to arbitrarilly execute scripts, which almost always means having shell access to your server, at a minimum. It is strongly encouraged that you have the ability to configure your machine's HTTP server. It is strongly discouraged to allow arbitrary execution of scripts from a web interface, as this is a major security hole.
