I'm surprised how many poor implementations I've seen of the nearest neighbor problem when the neighbor's latitude/longitude are known and stored in a database. The Haversine formula makes it soooo easy. Here is SQL you can use in mysql to get that done assuming the latitude is 37 and the longitude is -122 of the current location:

SELECT id, ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) )

* cos( radians( lng ) - radians(-122) ) + sin( radians(37) )

* sin( radians( lat ) ) ) ) AS distance

FROM markers

HAVING distance < 25

ORDER BY distance LIMIT 0 , 20;

BTW, the SQL is courtesy of google:
