Hello. I am currently working on developing a browser-based instant message service for the purpose of testing and having fun. First of all, I would like to do this with PHP. What I am asking for is some resources; a place to get started. A book recommendation would be phenomenal. I am not proficent in PHP but I believe a simple IM service can be accomplished with a minimal amount of scripting... I think this would be a great learning experience and hope that someone has some resources and/or tips.
