visitor ip

[psychohagis]

I want to know how you can get a visitors ip adress.  I know it can be done because a site I use sometimes block people from the whole site if they dont get the message to follow the rules (not speaking from experience).

Does anyone know how to do this. Im guessing its a global or something but i dont know what it is.

[code]
<?
function get_ip(){
if(!$ip=@$REMOTE_ADDR) $ip=$_SERVER['REMOTE_ADDR'];
return $ip;
}
$ip=get_ip();
$result=mysql_query("SELECT * FROM bannedips WHERE `ip`='$ip' LIMIT 1");
if(mysql_num_rows($result)!=0) die("You Were Banned!");
?>
[/code]
