我有一个小脚本，它告诉我谁在线 o 网站，但在 db 中由 ip2long 存储，我想存储用户的真实 IP 地址....请 sombody 可以帮助我吗？这是我的代码`

<?php

require "connect.php";
require "functions.php";

// We don't want web bots scewing our stats:
if(is_bot()) die();



$stringIp = $_SERVER['REMOTE_ADDR'];
$intIp = long2ip($stringIp);



// Checking wheter the visitor is already marked as being online:
$inDB = mysql_query("SELECT 1 FROM tz_who_is_online WHERE ip=".$intIp);

if(!mysql_num_rows($inDB))
{
    // This user is not in the database, so we must fetch
    // the geoip data and insert it into the online table:

    if($_COOKIE['geoData'])
    {
        // A "geoData" cookie has been previously set by the script, so we will use it

        // Always escape any user input, including cookies:
        list($city,$countryName,$countryAbbrev) = explode('|',mysql_real_escape_string(strip_tags($_COOKIE['geoData'])));
    }
    else
    {
        // Making an API call to Hostip:

        $xml = file_get_contents('http://api.hostip.info/?ip='.$stringIp);

        $city = get_tag('gml:name',$xml);
        $city = $city[1];

        $countryName = get_tag('countryName',$xml);
        $countryName = $countryName[0];

        $countryAbbrev = get_tag('countryAbbrev',$xml);
        $countryAbbrev = $countryAbbrev[0];

        // Setting a cookie with the data, which is set to expire in a month:
        setcookie('geoData',$city.'|'.$countryName.'|'.$countryAbbrev, time()+60*60*24*30,'/');
    }

    $countryName = str_replace('(Unknown Country?)','UNKNOWN',$countryName);

    // In case the Hostip API fails:

    if (!$countryName)
    {
        $countryName='UNKNOWN';
        $countryAbbrev='XX';
        $city='(Unknown City?)';
    }

    mysql_query("   INSERT INTO tz_who_is_online (ip,city,country,countrycode)
                    VALUES(".$intIp.",'".$city."','".$countryName."','".$countryAbbrev."')");
}
else
{
    // If the visitor is already online, just update the dt value of the row:
    mysql_query("UPDATE tz_who_is_online SET dt=NOW() WHERE ip=".$intIp);
}

// Removing entries not updated in the last 10 minutes:
mysql_query("DELETE FROM tz_who_is_online WHERE dt<SUBTIME(NOW(),'0 0:10:0')");

// Counting all the online visitors:
list($totalOnline) = mysql_fetch_array(mysql_query("SELECT COUNT(*) FROM tz_who_is_online"));

// Outputting the number as plain text:
echo $totalOnline;

?>




and this is for functions:


<?php


function get_tag($tag,$xml)
{
    preg_match_all('/<'.$tag.'>(.*)<\/'.$tag.'>$/imU',$xml,$match);
    return $match[1];
}

function is_bot()
{
    /* This function will check whether the visitor is a search engine robot */

    $botlist = array("Teoma", "alexa", "froogle", "Gigabot", "inktomi",
    "looksmart", "URL_Spider_SQL", "Firefly", "NationalDirectory",
    "Ask Jeeves", "TECNOSEEK", "InfoSeek", "WebFindBot", "girafabot",
    "crawler", "www.galaxy.com", "Googlebot", "Scooter", "Slurp",
    "msnbot", "appie", "FAST", "WebBug", "Spade", "ZyBorg", "rabaz",
    "Baiduspider", "Feedfetcher-Google", "TechnoratiSnoop", "Rankivabot",
    "Mediapartners-Google", "Sogou web spider", "WebAlta Crawler","TweetmemeBot",
    "Butterfly","Twitturls","Me.dium","Twiceler");

    foreach($botlist as $bot)
    {
        if(strpos($_SERVER['HTTP_USER_AGENT'],$bot)!==false)
        return true;    // Is a bot
    }

    return false;   // Not a bot
}
?>

IP 地址应作为ip2long函数的结果存储。然后，当您从数据库中获取结果时，您可以使用该long2ip函数将整数转换为点表示法 IP 地址。

准备要从数据库中插入的 IP 地址：

$ip = ip2long($_SERVER['REMOTE_ADDR']);

从数据库中取出一个数据库并以点分格式返回它：

$ip = long2ip($row['ip_address']);

简单的。
