330542 MYSQL order by proximity

Hi, I have a mysql db containing UIK postcode areas/towns and their latitudes and longitudes. I also have a very limited php script which will roughly pull out towns based on an area I specify. What I want is for the mysql query to order the returned towns/postcodes by their proximity to the starting long/lat coordinates - closest first. Shouldn't be too difficult for someone with mysql skills. Any q's please ask in PMB. This shouldn't be a big job so only bid if you know you can do this quick and make the bid sensible.
