You better reuse some existing PHP chat scripts like PHPFreeChat.

But if you want to make your own then here is an idea . You can setup own IRCD on the server or use some other available IRC networks.Then build a chat interface with PHP ,can search google for available PHP irc clients you will find many (modify it to your needs ;) .
