Looking for a Geolocation script

<?php
    // the function returns the ip address of the person viewing the page
    function userIP()
    {
        return (isset($_SERVER['HTTP_X_FORWARDED_FOR']) ? $_SERVER['HTTP_X_FORWARDED_FOR'] : $_SERVER['REMOTE_ADDR']);
    }
    
    //    here we include the necessary files for the geoip script
    include("./geoip/geoip.inc");
    include("./geoip/geoipcity.inc");
    include("./geoip/geoipregionvars.php");
    
    // we open the database file     
    $gi = geoip_open("./geoip/GeoLiteCity.dat", GEOIP_STANDARD);
    
    // we optain the necessary datails about the IP
    $rsGeoData = geoip_record_by_addr($gi, userIP());
    
    //close the database file
    geoip_close($gi);
        
    $city = ($rsGeoData->city);        // $city stores the name of the city coresponding to the IP 
    $randNr = rand(1000,2000);        // generate a random number between 1000 and 2000
    
    // because the accuracy of the data base is not 100% for every country
    // we show an alternative text if the city could not be found    
    if($city == ""){
        echo "[B]We`ve Found $randNr Black Singles in Your Area Online Now![/B]";
    }
    else{
