title: Post Code Lookup
body: <p>A client wants a page on their website where the user can search for a stockist of their product range. What they want is the ability to enter a UK PostCode and for a list of their stockists to appear in closest order.</p>
  
  <p>Is there a way to utilise Google Maps to determine the closest supplier?</p>
  
  <p>I have a PHP MySQL database with ALL the suppliers Postcodes and details and I'll have the postcode of the user to use as well.</p>
