The goal of the project is to construct a framework wherein I can maintain and update the website myself. The code I need involves utilizing the placemarks (military units) in the GE client, allowing the player to click a link (such as Move East 10 miles), this would then call up the php script on the server, which would change the unit's location accordingly by manipulating the main KML file that is network-linked to all players in the game.
Clicking on a player's city would allow him to build certain units, set tax rates, etc. Clicking on a unit would allow the player to set status (Normal, Repair, Training, etc.), move, combat, build, entrench, etc.
The key is to allow the players to move their units around the Google Earth client by simply click hyperlinks in the placemark's description baloon.
