hi

How to make web based yahoo messenger like meebo.com?

thanks

    Try googling for information on the Yahoo messenger protocol, or more specifically using it in PHP.

    I've no idea what kind of information is in this or how up to date it is, but may be worth a look:-
    Yahoo! Messenger Protocol Tutorial

    You might find some assistance in one of the open source messenger communities. Gaim for example...

    I presume you'll want an AJAX style interface so read up on DHTML, AJAX, etc...

      does anybody know any open source code for web based yahoo messanger like www.meebo.com ? Is there any API ?

      thanks.

        You'll need to be familiar with the AJAX techniques, and you'll probably need to use server-push. This is not straightforward as browsers (other than Mozilla) don't have any support for XMLHttpRequest server-push. Therefore, you need the "long-lived-iframe-requests" hack or something.

        It's not easy on the server-side easy, because PHP just isn't designed for this sort of thing. A prototype I wrote used unix datagram sockets for communication between multiple PHP instances; this is tricky to get right as it's concurrent programming.

        The makers of this sort of thing may just throw in the towel and write a custom single-threaded web server instead, as it would make it very much easier.
