第一种（使用CDN可正常获取访客ip）：

function get_real_ip()
{
    static $realip = NULL;
    if ($realip !== NULL) {
        return $realip;
    }

    if (isset($_SERVER)) {
        if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
            $arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
            foreach ($arr as $ip) {
                $ip = trim($ip);
                if ($ip != 'unknown') {
                    $realip = $ip;
                    break;
                }
            }
        } elseif (isset($_SERVER['HTTP_CLIENT_IP'])) {
            $realip = $_SERVER['HTTP_CLIENT_IP'];
        } else {
            if (isset($_SERVER['REMOTE_ADDR'])) {
                $realip = $_SERVER['REMOTE_ADDR'];
            } else {
                $realip = '0.0.0.0';
            }
        }
    } else {
        if (getenv('HTTP_X_FORWARDED_FOR')) {
            $realip = getenv('HTTP_X_FORWARDED_FOR');
        } elseif (getenv('HTTP_CLIENT_IP')) {
            $realip = getenv('HTTP_CLIENT_IP');
        } else {
            $realip = getenv('REMOTE_ADDR');
        }
    }

    preg_match("/[\d\.]{7,15}/", $realip, $onlineip);
    $realip = !empty($onlineip[0]) ? $onlineip[0] : '0.0.0.0';
    return $realip;
}

echo get_real_ip();

第二种：

function get_real_ip() {
    static $realip = NULL;
    if ($realip !== NULL) {
        return $realip;
    }
    if(getenv('REMOTE_ADDR')) {
        $realip = getenv('REMOTE_ADDR');
    }else if(getenv('HTTP_CLIENT_IP')) {
        $realip = getenv('HTTP_CLIENT_IP');
    }else if(getenv('HTTP_X_FROWARD_FOR')) {
        $realip = getenv('HTTP_X_FROWARD_FOR');
    } 
    return $realip; 
}

echo get_real_ip();

第三种：

function get_real_ip()
{
    static $realip = NULL;
    if ($realip !== NULL) {
        return $realip;
    }

    $client = @$_SERVER['HTTP_CLIENT_IP'];
    $forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
    $remote = $_SERVER['REMOTE_ADDR'];

    if (filter_var($client, FILTER_VALIDATE_IP)) {
        $realip = $client;
    } else if (filter_var($forward, FILTER_VALIDATE_IP)) {
        $realip = $forward;
    } else {
        $realip = $remote;
    }

    return $realip;
}

 echo get_user_ip();

把IPV4地址转化成int型

$ip = sprintf('%u', ip2long(get_real_ip()));
echo $ip;

把int型转化成IPV4地址

echo long2ip('2130706433');//127.0.0.1

生成随机ip

function rand_ip(){
   $ip2id= round(rand(600000, 2550000) / 10000);
   $ip3id= round(rand(600000, 2550000) / 10000);
   $ip4id= round(rand(600000, 2550000) / 10000);
   //下面是第二种方法，在以下数据中随机抽取
   $arr_1 = array("218","218","66","66","218","218","60","60","202","204","66","66","66","59","61","60","222","221","66","59","60","6066","218","218","62","63","64","66","66","122","211");
   $randarr= mt_rand(0,count($arr_1)-1);
   $ip1id = $arr_1[$randarr];
   return $ip1id.".".$ip2id.".".$ip3id.".".$ip4id;
}

echo rand_ip();
