problem with the $vbulletin object

[ghiboz]

Hi, this is a strange question, but I hope to someone help me to solve..
I explain.. i'm trying to make a thing like a bridge... for the first test I used to retrieve the logged user information...
to do this first thing i created a file test.php in the root of the forum and the code is this:

require("includes/config.php");
require("global.php");
print_r( $vbulletin->userinfo );

and if I go to my http://forum/test.php the result is the print array, and the vaues are ok...

second step I want check this thing from another place... so I use this code:

$fp = @fopen( "http://forum/test.php", 'r');
if( $fp )
{
    $html = "";
    while (!feof($fp))
    {
        $html .= fgets($fp, 128);
    }
    fclose( $fp );
}
else
{
    echo "error! page";
}
echo $html;

and also here I have the print array, but here the username is "unregistered" and all is like there's no user registered....
what can I solve this thing?
thanks in advance!
