title: Find ZIP Code from Latitude and Longitude
body: <p>I know there are web services out that have this information, however they can be limited to per day requests. I have about 114,000 records I need zip codes for. I have a data base full of zip codes with there lat and longs. However I am not sure how I can calculate the given lat and long against the zip code lat and long. </p>
  
  <p>Basically I need to cross reference the given address lat and long against the supplied zip code lat and long. I can either use PHP, Java, or MySQL Procedure or just a calculation. </p>
