I'm trying to use facebook connect in my site so users can register/login with it and I'm having a little bit of trouble understanding all the tutorials around the web.
My question is simple, does the facebook php client lib work in my use开发者_C百科 case or only to develop facebook applications that run inside fb ?
For Facebook Connect, you can use JS (as Amar) has suggested. Here's a tutorial that shows how to do that.
This tutorial should help you understand easily. I found it useful.
I know it has been awhile since you posted this but you should definitely try out the new Facebook PHP SDK (can be found here). With the new Graph API, the implementation of Facebook Connect has become very, very simple.
