How to get client ip address using php. But server in other country

我使用下面的条件。，但显示的是服务器的公网IP地址。这里我需要客户端的实际IP地址。，请帮帮我。

if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
    $ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
    $ip = $_SERVER['REMOTE_ADDR'];
}

使用此函数

 function get_client_ip() {
$ipaddress = '';
if (getenv('HTTP_CLIENT_IP'))
    $ipaddress = getenv('HTTP_CLIENT_IP');
else if(getenv('HTTP_X_FORWARDED_FOR'))
    $ipaddress = getenv('HTTP_X_FORWARDED_FOR');
else if(getenv('HTTP_X_FORWARDED'))
    $ipaddress = getenv('HTTP_X_FORWARDED');
else if(getenv('HTTP_FORWARDED_FOR'))
    $ipaddress = getenv('HTTP_FORWARDED_FOR');
else if(getenv('HTTP_FORWARDED'))
   $ipaddress = getenv('HTTP_FORWARDED');
else if(getenv('REMOTE_ADDR'))
    $ipaddress = getenv('REMOTE_ADDR');
else
    $ipaddress = 'UNKNOWN';
return $ipaddress;

}

试试这些:

$ip = getenv('HTTP_CLIENT_IP')?:
getenv('HTTP_X_FORWARDED_FOR')?:
getenv('HTTP_X_FORWARDED')?:
getenv('HTTP_FORWARDED_FOR')?:
getenv('HTTP_FORWARDED')?:
getenv('REMOTE_ADDR');
