Ip location finder - php

Question

I want to find the location (country, city,..) of my site visitor by their IP.
I'm coding php.
who can help me?
something like this:
$url = json_decode(file_get_contents("http://api.ipinfodb.com/v3/ip-city/?key=/*userapikey*/
ip=".$_SERVER['REMOTE_ADDR']."&format=json"));
$country=$url->countryName; // user country
$city=$url->cityName; // city
$region=$url->regionName; // regoin
$latitude=$url->latitude; //lat and lon
$longitude=$url->longitude;

Answer 1

Seems there is a & missing in the URL:
$url = json_decode(file_get_contents("http://api.ipinfodb.com/v3/ip-city/?key=/*userapikey*/&ip=".$_SERVER['REMOTE_ADDR']."&format=json"));
Probably, you should encode the IP:
$url = json_decode(file_get_contents("http://api.ipinfodb.com/v3/ip-city/?key=/*userapikey*/&ip=".urlencode($_SERVER['REMOTE_ADDR'])."&format=json"));
Then you can do this to get information about the result:
var_dump($url);
If you have another problem, please write it to the question.

Have a look at freegeoip.net. It's a webservice that gives you exactly the data you need for a specific IP.
E.g.:
https://freegeoip.net/json/1.2.3.4
will give you this JSON data:
{
ip: "1.2.3.4",
country_code: "US",
country_name: "USA",
region_code: "WA",
region_name: "Washington",
city: "Mukilteo",
zip_code: "98275",
time_zone: "America/Los_Angeles",
latitude: 47.945,
longitude: -122.305,
metro_code: 819
}
