php-websocket-client | A simple WebSocket WAMP client implemented in PHP | Websocket library

My unswer NO. You can not fully use the websocket client logick, using only the server part(for example php). Because the server side know anything about the browser. Server - receives a request and returns a static result. All magic in the browser is javascript. Javascript can dynamically listen all user events, post a query to server and insert a response from the server to the page. Websocket can not work without javascript in browser. This is WebSocket definition:

WebSockets are a bi-directional, full-duplex, persistent connection from a web browser to a server. Once a WebSocket connection is established the connection stays open until the client or server decides to close this connection. With this open connection, the client or server can send a message at any given time to the other. This makes web programming entirely event driven, not (just) user initiated. It is stateful. As well, at this time, a single running server application is aware of all connections, allowing you to communicate with any number of open connections at any given time.

The only thing you can do, is learn node js. It will allow you to write the browser (client) part and server part on one language - javascript. But however this will be different parts of application, and you will use different approaches, to program each part
