how to echo thing rorm the vbulletin var

[wouta]

Hi,

I trying to use the $vbulletin var. But i dont understand how i can use this array. When i echo something like $vbulletin->userinfo["username"] there is no problem. But when i try to echo $vbulletin->appname["lastvisit"] this most echo a mysql query i get nothing.

A other: When i try $vbulletin->session["location"] i get the follow message: Cannot use object of type vB_Session as array in

Is there someone who can tell me how i can use this array ?
