Tank Auth with Facebook Connect Authentication

[eluser]imcl[/eluser]
hey there friends, I've been using @eric's library for a while now and it's working great.

one of the early posts of this thread asks how to use this code to allow for posting to user's FB wall.

erics response:

Code:

...
$url = “https://graph.facebook.com/FACEBOOK_USER_ID/feed”
$attachment = array(“access_token” => get the access token, “name”=>“hello world”, “link”=>“http://myapp.com”, “description”=>“My first post to Facebook wall”);

You now have the URL and the data that you are going to post to your wall. You can then use CURL to post this. Hope that helps!

I really have no idea how to code the CURL after defining the variables above.

And how do I get the access token?

Can anyone give a hint how to post a message to my wall on FB?
