在需要的位置放以下代码:
{dede:PHP}
$user_IP = ($_SERVER["HTTP_VIA"]) ?
$_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
$user_IP =
($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
function get_real_ip(){
$ip=false;
if(!empty($_SERVER["HTTP_CLIENT_IP"])){
$ip =
$_SERVER["HTTP_CLIENT_IP"];
}
if
(!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$ips = explode (",",$_SERVER['HTTP_X_FORWARDED_FOR']);
if ($ip) { array_unshift($ips,$ip); $ip
= FALSE; }
for ($i = 0; $i < count($ips); $i++) {
if (!eregi
("^(10│172.16│192.168).",$ips[$i])) {
$ip = $ips[$i];
break;
}
}
}
return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
echo
"YOUR IP "." ". get_real_ip();
