List of variables

[eob]

I'm also on the road to writing my first hack, so I'd like to know what's involved in using global.php to grab user information. I noticed that some hacks seem to use the VBB cookie, rather than VBB itself to connect up and grab VBB user information etc, what's the deal here?

If I run code like this

PHP Code:

include (global.php)

(list ($key,$value)) $bbuserinfo {echo $key $value} 


(pseudo code) will it work, or does it get more complicated than that?

Is there a beginners guide for hackers available or what's the story there?
