<?php          $ip = $_server['remote_addr'];         $url = "http://api.ipinfodb.com/v3/ip-city/?key=<api key>&ip=$ip&format=json";           $ch = curl_init(); // start curl         curl_setopt($ch, curlopt_url, $url); // set url         curl_setopt($ch, curlopt_returntransfer, true); // response variable         curl_setopt($ch, curlopt_httpget, true);         curl_setopt($ch, curlopt_fresh_connect, true);               $response = curl_exec($ch); // connect , response          curl_close($ch);             $json_response = json_decode($response, true);          echo "<pre>";         print_r($json_response);         echo "</pre>"; ?>
