Maybe this helps you: http://www.scribd.com/doc/2569355/Geo-Distance-Search-with-MySQL
It is a nice introduction. Or just google for
mysql distance queries, you will find some tutorials.If you have the possibility and want to have it easier, switch to PostgreSQL which supports distance queries out of the box.
