Share 1 set vbulletin code with multi vbulletin forums in one host

If you have several vbulletin licenses, and you only have very small web hosting. I can tell you a skill on how to share one set vbulletin code with multi vbulletin licenses.

add the following to config.php.

'configlocalhost.php',
'127.0.0.1'=>'config127.php',
);
$url = $arrays[$_SERVER['HTTP_HOST']];
include $url;
?>

and change the other 2 forums’ config.php to configlocalhost.php and config127.php.

that’s all.
