文章采取新浪开放的API，直接上代码，没多少说的

/**
* 获取用户真实的ip地址
*/
function GetIp(){
$realip = '';
$unknown = 'unknown';
if (isset($_SERVER)){
if(isset($_SERVER['HTTP_X_FORWARDED_FOR']) && !empty($_SERVER['HTTP_X_FORWARDED_FOR'])
&& strcasecmp($_SERVER['HTTP_X_FORWARDED_FOR'], $unknown)){
$arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
foreach($arr as $ip){
$ip = trim($ip);
if ($ip != 'unknown'){
$realip = $ip;
break;
}
}
}else if(isset($_SERVER['HTTP_CLIENT_IP']) && !empty($_SERVER['HTTP_CLIENT_IP'])
&& strcasecmp($_SERVER['HTTP_CLIENT_IP'], $unknown)){
$realip = $_SERVER['HTTP_CLIENT_IP'];
}else if(isset($_SERVER['REMOTE_ADDR']) && !empty($_SERVER['REMOTE_ADDR'])
&& strcasecmp($_SERVER['REMOTE_ADDR'], $unknown)){
$realip = $_SERVER['REMOTE_ADDR'];
}else{
$realip = $unknown;
}
}else{
if(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), $unknown)){
$realip = getenv("HTTP_X_FORWARDED_FOR");
}else if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), $unknown)){
$realip = getenv("HTTP_CLIENT_IP");
}else if(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), $unknown)){
$realip = getenv("REMOTE_ADDR");
}else{
$realip = $unknown;
}
}
$realip = preg_match("/[\d\.]{7,15}/", $realip, $matches) ? $matches[0] : $unknown;
return $realip;
}
