I would recommend a framework instead, but hey, you have that freedom of choice in PHP :)

There're a lot of people don't know how to install libraries in PHP. If I would suggest a library, I'll suggest SimpleBotAPI.

Are you still updating your library? If not, which PHP library do you recommend?

Besides the one from unreal4u that's the other one I knew on Github. Till now I used my own simple framework, but I don't have the time anymore, so have to switch to unreal4u or the one from longman
