Creating an IM bot

Question

I am trying to create an IM bot and I haven't been able to find the necessary resources.

---

UPDATE

There was an issue with Imified making gtalk bots not appear online (and not responding), it works now so I'm closing this.

This tutorial does work.

Original question not deleted for reference purposes

First, I did find a great tutorial on How to Write Your Own IM Bot, but it uses the IMified platform which looks dead (last blog post in septembre 2008, no feedback on their help forum, ...).

I did manage to create a beta bot using their service but as I can see in their help forum, it will never be online.

So, any one managed to do it?

Notes

I'm looking for something that would be:

• Free
• Works with PHP* or some free hosting solution (like IMified but that works)
• Works for Google Talk (I don't really care about the other)

Of course, do post answers about any solution that doesn't fit these criteria, it might help.

*I have a Linux hosting plan on GoDaddy

Answer 1

Google Talk uses jabber, where the protocol is called XMPP. A quick google search for "xmpp bot php" led me here. This should be enough for a start ?
