Geocoding with PHP and the Google Maps API

Hi There, I would like a user to find a specific address then also have a list of all the suburbs within a 15km radius of that address? Has anybody got a clue or something similar? Much Appreciated...

cheers for the easy to use geocoder :)

Thanks for the article. You had mentioned something at the end about creating a caching solution. I have a table in my DB that containts the fields, (user_id, lat, lon) I want to be able to assign the returned latitude, and longitude with the highest accuracy to vaiables for easy database entry, I also want to be able to get the Address, city, state, and zip that is returned from the geocoder to maitain database consistancy. What syntax would I use and which class would I add it to to accomplish this task. I am not too familiar iwth OOP, so any help would be apreciated.

I uploaded all the files and tested test.php, but was stopped short by a fatal error message -- no cURL support on my server. I then edited Geocoder.php to make it use fopen() instead of curl functions and it seems to work.

I am uncertain, though, if the original and my version work exactly the same. Maybe someone can advise?

<?php
    // Geocoder.php 
    // I changed lines 32-35 ... 
    
    $ch = curl_init($url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    $response = curl_exec($ch); 
    curl_close($ch); 
    
    // ...into...
    
    $handle = fopen($url, "rb"); 
    $response = stream_get_contents($handle); 
    fclose($handle);
?>
