方法一:
<?php
function GetIP(){
if(!empty($_SERVER["HTTP_CLIENT_IP"])){
  $cip = $_SERVER["HTTP_CLIENT_IP"];
}
elseif(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])){
  $cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
}
elseif(!empty($_SERVER["REMOTE_ADDR"])){
  $cip = $_SERVER["REMOTE_ADDR"];
}
else{
  $cip = "无法获取!";
}
return $cip;
}
echo GetIP();
?>

方法二:
<?php
error_reporting (E_ERROR | E_WARNING | E_PARSE);
if($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"]){
$ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"];
}
elseif($HTTP_SERVER_VARS["HTTP_CLIENT_IP"]){
$ip = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"];
}
elseif ($HTTP_SERVER_VARS["REMOTE_ADDR"]){
$ip = $HTTP_SERVER_VARS["REMOTE_ADDR"];
}
elseif (getenv("HTTP_X_FORWARDED_FOR")){
$ip = getenv("HTTP_X_FORWARDED_FOR");
}
elseif (getenv("HTTP_CLIENT_IP")){
$ip = getenv("HTTP_CLIENT_IP");
}
elseif (getenv("REMOTE_ADDR")){
$ip = getenv("REMOTE_ADDR");
}
else{
$ip = "Unknown";
}
echo $ip;
?>

方法三:
<?php
$iipp = $_SERVER["REMOTE_ADDR"];
echo $iipp ;
?>

方法四:
<?php
$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
echo $user_IP
?>

方法五:
<?php
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 get_real_ip();
?>

方法六:
<?php
if(getenv('HTTP_CLIENT_IP')){
$onlineip = getenv('HTTP_CLIENT_IP');
}
elseif(getenv('HTTP_X_FORWARDED_FOR')){
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
}
elseif(getenv('REMOTE_ADDR')){
$onlineip = getenv('REMOTE_ADDR');
}
else{
$onlineip = $HTTP_SERVER_VARS['REMOTE_ADDR'];
}
echo $onlineip;
?>

}
return preg_match ( '/[\d\.]{7,15}/', $ip, $matches ) ? $matches [0] : '';
}
