PHP Function to return Country and City from an IP Address

Thursday, October 27, 2011

 Here is a PHP function which can return the Geo location of the submitted IP address. The function uses a free IP Locator API provided by http://ipinfodb.com/

For using this service you have to register to this website and they will provide you with an API key, with which you can access this free webservice.

The function below will return the Country and City of the supplied IP Address.

More details after this code


///////////// Code Start ////////////////////


function countryCityFromIP_CURL($ipAddr){

$contents ="";
/**
* Initialize the cURL session
*/
$ch = curl_init();
    $ipDetail=array(); //initialize a blank array
/**
* Set the URL of the page or file to download.
*/

$api_key="YOUR API KEY";
$api_url= "http://api.ipinfodb.com/v2/ip_query.php?key=".$api_key."&ip=".$ipAddr."&timezone=false";


curl_setopt($ch, CURLOPT_URL, $api_url );
curl_setopt($ch,CURLOPT_TIMEOUT,20); 

/**
* Ask cURL to return the contents in a variable
* instead of simply echoing them to the browser.
*/
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
/**
* Execute the cURL session
*/
$contents = curl_exec ($ch);
/**
* Close cURL session
*/
curl_close ($ch);

$contents=trim($contents);

//echo( htmlentities($contents) );

//check whether it is a valid  XML response



if( stripos($contents,"CountryName") >0 && stripos($contents,"CountryCode") >0  ){


$xml_parser = xml_parser_create();
xml_parse_into_struct($xml_parser, $contents, $vals, $index);
xml_parser_free($xml_parser);

$params = array();
$level = array();
foreach ($vals as $xml_elem) {
  if ($xml_elem['type'] == 'open') {
    if (array_key_exists('attributes',$xml_elem)) {
      list($level[$xml_elem['level']],$extra) = array_values($xml_elem['attributes']);
    } else {
      $level[$xml_elem['level']] = $xml_elem['tag'];
    }
  }
  if ($xml_elem['type'] == 'complete') {
    $start_level = 1;
    $php_stmt = '$params';
    while($start_level < $xml_elem['level']) {
      $php_stmt .= '[$level['.$start_level.']]';
      $start_level++;
    }
    $php_stmt .= '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';
    eval($php_stmt);
  }
}

                return  $params['RESPONSE'];
}else
        return NULL;

}


///////////// Code End ////////////////////

        if( is_array($IPDetails) ){
        //country  and city of that IP address
        $userCountry=$IPDetails['COUNTRYNAME'];
        $countryCode=$IPDetails['COUNTRYCODE'];
        }
