My vbulletin version:3.8.3
my code:
if ((!$this->registry->userinfo[userid]) OR (is_member_of($this->registry->userinfo, 1, 3)))
{
$this->post['message'] = preg_replace("!<a[^>]*(http|www)(.*)</a>!siU",
<b><font color="white">To view the link you have to <a href="login.php">Login</a> or <a href="register.php">Register</a></b></font>, $this->post['message']);
}

And i get this error when i open post as guest:
Parse error: syntax error, unexpected '<' in /home/datoneer/public_html/includes/class_postbit.php(294) : eval()'d code on line 90

Help please??
