To retrieve the weather forecast for your location based only on your current IP, the full tutorial will have the following 5 sections (, that will:
- Describe elements needed for weather forecast retrieval
- Describe the weather station code field of IP2Location
- Show code that gets the weather station code from IP address
- Show code that retrieves the weather forecast from Yahoo! Weather using the weather station code.
- Show code that retrieves the weather forecast using IP2Location

Here, I will only show you how to retrieve the weather forecast.

  1. //includes the IP2Location framework
  2. require_once('IP2Location.php');
  4. //function that sends and retrieves an answer from a HTTP request
  5. function SendRequest( $url, $method = 'GET', $data = array(), $headers = array('Content-type: application/x-www-form-urlencoded') )
  6. {
  7. $context = stream_context_create(array
  8. (
  9. 'http' => array(
  10. 'method' => $method,
  11. 'header' => $headers,
  12. 'content' => http_build_query( $data )
  13. )
  14. ));
  16. return file_get_contents($url, false, $context);
  17. }
  19. //the client's IP
  20. $ip = $_SERVER['REMOTE_ADDR'];
  21. // Standard lookup with no cache
  22. $loc = new IP2Location('databases/db24.bin');
  25. $stationCode=FindIPWeatherStationCode($ip,$loc);
  26. GetWeatherForecastFromYahoo($stationCode);

Virus note: All files are scanned once-a-day by for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
