Need a php based chat script to provide website members chat functionallity with visitors?

PHP is one of the worst things you can use for that. If you want a chat, embed an AJAX-based IRC chat (qwebirc for networks like gamesurge, freenode and quakenet; mibbit for others) or if it has to be a purely web-based chat use something that actually runs a chat server daemon so it can use techniques like COMET/long-polling and doesn't have to hammer your server with requests to check if something new has been written.

I know about Ajax, its just I don't want to code from the scratch thats why I am asking for a open source script or some guide line from where I shud start. Also I will not use this script on my main server, I will setup a new server for chat. – madforstrength Mar 8 at 11:19.

Php has web-socket and support forking, too. It is just not that academic language!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
