Looks good. I do have a couple of suggestions though:

Your main function is used recursively and never returns. This is very memory inefficient and will fill php's call stack quickly. You should change it to use a infinite look instead.

The use of $GLOBALS makes me sad, especially since you are using a class and could have made the global variables a property of the class.

i tried using $config to hold the phrases but couldn't seem to set them @ runtime ... php isn't my favoured language and i threw this together in a couple of nights

points taken tho ... ill try and improve on the code

... the infinite loop was in the original bit of source i used to make the bot

thanks for checking it though :D
