485563 PHP & Ajax Game Map

I am in need of a PHP & Ajax game map for GGLegends ([login to view URL]). I know that this is very possible with Flash and Java, but am not looking to use either of those. - Only show 10x10 of the game map at a time along with arrows to scroll left, right, up, down. - When a user registers or doesn't have any map coordinates, we need to store a random x and y coordinate in the database per player that hasn't already been used. - Map needs to display player location based on their x&y coordinates. Where a user doesn't exist, terrain needs to be generated. - Needs to be very well commented so I can make changes.
