How Do I Get a Visitor's Location Information using PHP?

Sometimes we have content that is specific to a certain country and we only want to show, or hide, it for visitors from that country. Or maybe we want to change some of the language used on a page to cater to different cultures to improve our targeted marketing strategies. We can do this easily with the PHP function below. Once we get the information we need, using a few conditionals will allow you to show, hide or change content depending on where your visitor is from!

<?php
function ip_info($ip = NULL, $purpose = "location", $deep_detect = TRUE) {
$output = NULL;
if (filter_var($ip, FILTER_VALIDATE_IP) === FALSE) {
$ip = $_SERVER["REMOTE_ADDR"];
if ($deep_detect) {
if (filter_var(@$_SERVER['HTTP_X_FORWARDED_FOR'], FILTER_VALIDATE_IP))
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
if (filter_var(@$_SERVER['HTTP_CLIENT_IP'], FILTER_VALIDATE_IP))
$ip = $_SERVER['HTTP_CLIENT_IP'];
}
}
$purpose = str_replace(array("name", "\n", "\t", " ", "-", "_"), NULL, strtolower(trim($purpose)));
$support = array("country", "countrycode", "state", "region", "city", "location", "address");
$continents = array(
"AF" => "Africa",
"AN" => "Antarctica",
"AS" => "Asia",
"EU" => "Europe",
"OC" => "Australia (Oceania)",
"NA" => "North America",
"SA" => "South America"
);
if (filter_var($ip, FILTER_VALIDATE_IP) && in_array($purpose, $support)) {
$ipdat = @json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip=" . $ip));
if (@strlen(trim($ipdat->geoplugin_countryCode)) == 2) {
switch ($purpose) {
case "location":
$output = array(
"city" => @$ipdat->geoplugin_city,
"state" => @$ipdat->geoplugin_regionName,
"country" => @$ipdat->geoplugin_countryName,
"country_code" => @$ipdat->geoplugin_countryCode,
"continent" => @$continents[strtoupper($ipdat->geoplugin_continentCode)],
"continent_code" => @$ipdat->geoplugin_continentCode
);
break;
case "address":
$address = array($ipdat->geoplugin_countryName);
if (@strlen($ipdat->geoplugin_regionName) >= 1)
$address[] = $ipdat->geoplugin_regionName;
if (@strlen($ipdat->geoplugin_city) >= 1)
$address[] = $ipdat->geoplugin_city;
$output = implode(", ", array_reverse($address));
break;
case "city":
$output = @$ipdat->geoplugin_city;
break;
case "state":
$output = @$ipdat->geoplugin_regionName;
break;
case "region":
$output = @$ipdat->geoplugin_regionName;
break;
case "country":
$output = @$ipdat->geoplugin_countryName;
break;
case "countrycode":
$output = @$ipdat->geoplugin_countryCode;
break;
}
}
}
return $output;
}

// Example 1: Get visitor IP address details
<?php

echo $country = ip_info("Visitor", "Country"); // India
echo $countryCode = ip_info("Visitor", "Country Code"); // IN
echo $state = ip_info("Visitor", "State"); // Andhra Pradesh
echo $city = ip_info("Visitor", "City"); // Proddatur
echo $address = ip_info("Visitor", "Address"); // Proddatur, Andhra Pradesh, India

print_r(ip_info("Visitor", "Location")); // Array ( [city] => Proddatur [state] => Andhra Pradesh [country] => India [country_code] => IN [continent] => Asia [continent_code] => AS )

?>


// Example 2: Get details of any IP address. [Support IPV4 & IPV6]
<?php

echo $country = ip_info("173.252.110.27", "Country"); // United States
echo $countryCode = ip_info("173.252.110.27", "Country Code"); // US
echo $state = ip_info("173.252.110.27", "State"); // California
echo $city = ip_info("173.252.110.27", "City"); // Menlo Park
echo $address = ip_info("173.252.110.27", "Address"); // Menlo Park, California, United States

print_r(ip_info("173.252.110.27", "Location")); // Array ( [city] => Menlo Park [state] => California [country] => United States [country_code] => US [continent] => North America [continent_code] => NA )

?>
