GeoLocation using PHP

I copied paste following code and I am a noob at this. So can you point out error please? I am sorry for asking such a stupid question.

<HTML>

<HEAD>
</HEAD>

<BODY>
    <h3>Client side IP geolocation using <a href="http://ipinfo.io">ipinfo.io</a></h3>
    <hr/>
    <div id="ip"></div>
    <div id="address"></div>
    <hr/>Full response: <pre id="details"></pre>
</BODY>

</HTML>
<script type="text/javascript" charset="utf-8">
$.get("http://ipinfo.io", function(response) {
    $("#ip").html("IP: " + response.ip);
    $("#address").html("Location: " + response.city + ", " + response.region);
    $("#details").html(JSON.stringify(response, null, 4));
}, "jsonp");
</script>

Solution

HtML5 using get user latitude, longitude and get current user address.

Sample code:

<!DOCTYPE html>
<html>
    <head>
        <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
        <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&signed_in=true"></script>
    </head>
    <body>
        <p>Address: <div id="address"></div></p>
    </body>
    <script type="text/javascript" charset="utf-8">
    $(document).ready(function() {

        var currgeocoder;

        //Set geo location lat and long
        navigator.geolocation.getCurrentPosition(function(position, html5Error) {
            geo_loc = processGeolocationResult(position);
            currLatLong = geo_loc.split(",");
            initializeCurrent(currLatLong[0], currLatLong[1]);
        });

        //Get geo location result
        function processGeolocationResult(position) {
            html5Lat = position.coords.latitude; //Get latitude
            html5Lon = position.coords.longitude; //Get longitude
            html5TimeStamp = position.timestamp; //Get timestamp
            html5Accuracy = position.coords.accuracy; //Get accuracy in meters
            return (html5Lat).toFixed(8) + ", " + (html5Lon).toFixed(8);
        }

        //Check value is present or
        function initializeCurrent(latcurr, longcurr) {
            currgeocoder = new google.maps.Geocoder();

            console.log(latcurr + "-- ######## --" + longcurr);

            if (latcurr != '' && longcurr != '') {
                //call google api function
                var myLatlng = new google.maps.LatLng(latcurr, longcurr);
                return getCurrentAddress(myLatlng);
            }
        }

        //Get current address
        function getCurrentAddress(location) {
            currgeocoder.geocode({
                'location': location
            }, function(results, status) {
                if (status == google.maps.GeocoderStatus.OK) {
                    console.log(results[0]);
                    $("#address").html(results[0].formatted_address);
                } else {
                    alert('Geocode was not successful for the following reason: ' + status);
                }
            });
        }
    });
    </script>
