Get a Visitor’s Location Information using PHP

Buttons Kavanagh

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(
