請問下,用PHP獲取瀏覽當(dāng)前用戶的IP地址,用什么方法啊?我查了一下,都說是用$_SERVER['REMOTE_ADDR'],但是這個獲取的結(jié)果并不是公網(wǎng)IP呀.

public function ip($type = 0, $adv = true)

{
    $type      = $type ? 1 : 0;
    static $ip = null;

    if (null !== $ip) {
        return $ip[$type];
    }

    if ($adv) {
        if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
            $arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
            $pos = array_search('unknown', $arr);
            if (false !== $pos) {
                unset($arr[$pos]);
            }
            $ip = trim(current($arr));
        } elseif (isset($_SERVER['HTTP_CLIENT_IP'])) {
            $ip = $_SERVER['HTTP_CLIENT_IP'];
        } elseif (isset($_SERVER['REMOTE_ADDR'])) {
            $ip = $_SERVER['REMOTE_ADDR'];
        }
    } elseif (isset($_SERVER['REMOTE_ADDR'])) {
        $ip = $_SERVER['REMOTE_ADDR'];
    }

    // IP地址合法驗證
    $long = sprintf("%u", ip2long($ip));
    $ip   = $long ? [$ip, $long] : ['0.0.0.0', 0];

    return $ip[$type];
}

直接拿去用
