global.php include

[t0ny]

I have a file outside of vb with the following code:

<?php  
//Store current directory
$cwd = getcwd();
echo getcwd().'\n';
//change to forum directory
chdir ('../forum');
echo getcwd() . '\n';

require_once('global.php');
if ($vbulletin->userinfo['userid'])  
{  
    echo 'Welcome ' . $vbulletin->userinfo['username'] . ', you have logged in.';  
}  
else  
{  
    echo 'Not logged in...';  
} 
//return to original directory
chdir ($cwd);
echo getcwd().'\n';
?>

I am getting this error when I use it :

Unable to add cookies, header already sent.

Can anyone help??

That is because you cannot have any HTML output before the headers (cookies) are defined. E.g., no output before global.php is included.
