title: Cities within radius from current coordinates PHP API
body: <p>Well fellow programmers,</p>
  
  <p>I got myself in a situation.</p>
  
  <p>I am currently developing an API for a taxi application. The taxi want's to show advertisements from the current area. Now i need to specify in the Admin panel what the banner image is and the main location. Aswell as a radius in KM to show this ad aswell.</p>
  
  <p>My question. Is there a simple API which i can fill in my current location and get all nearby citynames within the radius i provide aswell?</p>
  
  <p>i am looking for something like this : <a href="http://www.travelmath.com/cities-within/10+km/of/Rotterdam,+Netherlands" rel="nofollow">http://www.travelmath.com/cities-within/10+km/of/Rotterdam,+Netherlands</a> but then an API with JSON return.</p>
