title: Refresh JSON using PHP (Weather Underground API)
body: <p>I'm using the Weather Underground API to show live weather data on a PHP page. However, I'd like to have the weather values automatically refresh every 5 minutes (as opposed to refreshing the entire web page). Is there a way for the values to refresh themselves (ie. temperature, wind, etc)?</p>
  
  <p>I'm calling the information like this:</p>
  
  <pre><code>$json_string = file_get_contents('http://api.wunderground.com/api/[key]/geolookup/conditions/forecast/q/TX/Austin.json');
      $json_b = json_decode($json_string);
  </code></pre>
  
  <p>Forgive the question; I'm still very new to all this, and couldn't find an answer that worked in my coding. Thanks</p>
