I am currently woring on a project wich involves Flash, XML, MySql, PHP. I have to populate flash map with countries & upon clicking cities from the database. But the thing is the cities can keep on changing, some may be deleted & new ones can be added. So the solution i have developed revolves around rewriting the city.xml when a country is clicked. Is there a better solution, something that will directly pass values to the flash file without writing to the file itself & save me some valuble I/O time ?
