Sometimes we may need to know geocode of some specific postal location. For example, you have some shops catalogue and want to show shop locations on the map. Then, you will need to ask some service about map marker coordinates.This small library can help you to get reliable geocode results for most of user-provided postal addresses.
At this moment (version 1.0) this library can use Google Maps API, Yahoo Maps Services, Geocoder.us and Geocoder.ca services, but it is easily extensible and I can almost any services there. So, if you know some other services, that providing longitude/latitude pair by postal address, drop me a note and I will try to add its support to library.
Using UltimateGeoCoder library you can ask some specific addresses or simply call library-embedded service multiplexing function, that will try appropriate services and then will return results to you (this approach is really reliable comparing to use of one service).
Prerequisites: PHP 5.0+ with simplexml and fread() from URLs support. If you want to use curl for HTTP-requests, you can simply use my class as base for yours and override string fetchURL($url) method to change the way URLs are fetched.
Download: Latest version of library is 1.0 (September, 7, 2006). You can get it here: Ultimate Geo Coder v. 1.0
