Integrating a JavaScript chat in a php web based game

Is it possible to implement a JavaScript plugin/app in a web text based game? if it is, how is this done. I don't really need the codes. All I want is the function开发者_如何学Cality. Basically, I want a player in the game to talk to another player in the same game. Like if he(player) enters a room, I want him to see a player and communicate with him or her. Remember, it is chatting with another player, not another user.

Also, I want the php code used to integrate this app onto the site.

WebSockets are part of HTML5 and fit in my webbased game just neatly. There is a full guide on http://net.tutsplus.com/tutorials/javascript-ajax/start-using-html5-websockets-today/

you can use long polling with js/jquery ajax calls to the php scripts and the database (or files) to make a chat like program

Try searching for some open/free libraries that you can integrate with your game if you don't want to spend time implementing the chat part yourself. I just found this - https://blueimp.net/ajax/ but I have not used it, so you may want to take a look at the features and if it works for you.
