log in/out vbulletin on a non vbulletin page

Anybody know? HELP PLEASE!!

why not you create session for this...
then you can check whether session is there or not...if ,you can print username and logout ..if session is not there the display normal login box...
if your requirement is something else than my post,,let me know...

I understand where you are coming from - that is what i wanted to do. But i am a noobie! to this programming so do you know the code that i would use?
Many Thanks

go through this url..code yourself for your requirement..if any errors occur,then let do post here..

My problem is that vbulletin is different to normal log in. I have got the log in bit right but wanted to know how to change to log out once logged in. Do you use the if...else... - if so, how would you do it is it "if [member].."??
Many Thanks

I have tried creating some code but it is not working here is the code:

<?php 
		if($member){

// output some text
echo 'Username:
'.$info["username"].'
Registered on:
'.$info["regdate"];

// if the user ISN'T logged in
}else{

// output an error
echo 'Please Log in';}
?>

I am not sure what you have to type in for it to work with vbulletin. I am completely stuck!! Really need help!
Thanks to everyone who helps

I have made some progress, i have used the php "if & "else" to display login or logout. However when logged in all is fine - it displays "welcome... & logout" BUT when you are not logged in and i want the login box to appear this message appears: "Unable to add cookies, header already sent.
