This presentation covers the use of geolocation information with PHP. I will start with a theorectical background of all the services, mapping systems etc involved. After that I will discuss how to use geo-services from PHP from obtaining geo-location information through databases and services, mapping services for visualisation of geo-aware data to geo-aware data storage, manipulation and querying.
