Re: [UMN_MAPSERVER-USERS] how to find bounding county for given long/lat?

[Hal Mueller]

In PHP Mapscript, the queryby... methods on the Layer class 
(http://mapserver.gis.umn.edu/docs/reference/phpmapscript-class/classes/layerobj 
) appear to do what you want--find the shape that matches the 
coordinates.  From there you can query the shape's attributes, get 
its FIPS code, and hit your database.
