PHP is probably not the best way to handle this. There is no way to
notify the client that there has been an update (HTML is
request/response - you must have a request before you can send a
response). Either you're going to have to use javascript to keep
refreshing the window, or the user will need to keep hitting the refresh
button on the browser. Either way would be awkward and put an
unnecessarily high load on the server.
Better would be to do it with something like a Java applet.
