title: Getting FaceBook Account Info with PHP After FB Authentication on Website
body: <p>I'm reading through the Facebook Connect guide and have managed to get the authentication feature running, so that a user can register for a website via their FaceBook accounts.  On the registration page, users can enter their FB account info (if they're not alrady signed in) and after confirming the form is posted to a processing page.  On the processing page I want to grab their username and e-mail from their FaceBook account and enter it into a MySQL table using PHP, but I'm not sure how to get the info.  I tried var_dump($_POST) to see what was being passed, but I don't see the info I need.  How can I do this?  Thanks.</p>
