An AIML Interpreter written in PHP with MySQL. Have your own chatbot on your website, the chat engine is writen in PHP, with the AIML initially parsed into a MySQL database. If you would like a demo or more info please visit http://www.program-o.com
THIS PROJECT HAS NOW BEEN MOVED TO https://github.com/Program-O/Program-O
Program-O has a nice admin interface, an AIML upload utility, and an active support community for help. I was able to modify the source to customize to my needs, but when I hit a wall, the forums were very helpful.
