is_member_of gives mixed results?

[Kyojii]

Here's an easier example of my problem.
<?php
require_once("./global.php");
echo is_member_of($vbulletin->userinfo, 6);
?>
Result: 1 (true)


<?php
require_once('./global.php');

function allowaccess() {
if (is_member_of($vbulletin->userinfo, 6)){
return 1;
}
else{
return 0;
}
}
echo allowaccess();
?>
Result: 0 (false)

I got around this by instead of making my own function just making an array of users I wanted to be able to access the page and including the file on every page.

$vbulletin isn't global in your function and you haven't passed the value $vbulletin, so it's false (empty).
