title: Query shapefiles for the administrative area of a lat/lng
body: <p>I have the all the shapefiles (shp, dbf, ...) for my country's counties. I have a list of points (latitude/longitude) and need to reference each point with corresponding county.</p>
  
  <p>I have looked into these <a href="http://shapelib.maptools.org/shapelib-tools.html" rel="nofollow noreferrer">tools</a> and <a href="http://www.phpclasses.org/browse/package/1741.html" rel="nofollow noreferrer">libraries</a>. They can read, write and edit SHP files, but don't seem to be able to search stuff on them. I have converted the DBF file into MySQL (<a href="http://sourceforge.net/projects/shp2mysql-php/" rel="nofollow noreferrer">using this</a>) but this data is just meta-data, not the actual polygons.</p>
  
  <p>Do we need to convert SHP geometry units to lat/lng? Is there any tool/lib/package to do it?
  Rather new to geo-stuff. ;)</p>
  
  <p>thanks! cheers</p>
