Retrieve bounding coordinates and distances with GeoLocation. You can also calculate and measure the distance between geopoints with this php class.
This is a PHP port of Java code that was originally published at
http://JanMatuschek.de/LatitudeLongitudeBoundingCoordinates. A few modifications were made and an additional helper method to retrieve latitude and longitude from an address has been provided using Google's Geocoding API.
