Geocoding mit PHP und der Google Maps API
phpriot erklärt die Google Maps Web Services API.
Geocoding is the process of finding the longitude and latitude of a given address or location. The Google Maps service gives developers and web site owners free access to their geocoder, both using the Google Maps JavaScript API, as well as using the web service. In this article I will show you how to access the geocoder web service using PHP so that it can be used in your own applications. (…) When using Google Maps to display maps on your web site, it is easy to access the JavaScript based geocoder, however this isn’t always an adequate solution, especially when it comes to accessibility.
For example, if your application saves coordinates based on a user-submitted address using the JavaScript geocoder, then this solution will not work for users who have JavaScript disabled. To overcome this we can use the web service instead, meaning all requests to the geocoder are performed on the server side.
