Sorry, you did say you were looking for where the sql is built. There's another function called fetch_userinfo (with parameters) that's in includes/functions.php.

The & means the function returns a reference (you might want to look at this: http://us2.php.net/manual/en/language.references.php if you haven't already). Without that the returned value would be a copy. Say you had, for instance, an array somewhere that was being used to cache user info (to avoid doing the sql for a particular user more than once). If a function returned a value from that array, any changes to the returned userinfo wouldn't change the cached value. But if the function returns a reference, then any changes *would* change the cached value. I hope that makes some sense.
