A Quick Weather API with PHP

I wanted to add a small weather status to the top of a web application, just to remind me what was going on in that city. This is some really simple code, based off of WunderGround’s API, using a city airport’s conditions. Not going into much detail on this, or offering a completely robust solution, but here is the code I have in place.

  $url = 'http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=KSFO';
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_TIMEOUT, 10);
  $data = curl_exec($ch);
  curl_close($ch);

  $xml = simplexml_load_string($data);

  $weather = $xml->weather;
  $temp = $xml->temp_f;
  $icon = $xml->icons->icon_set[9]->icon_url;

From this, you can set the three parsed variables into your html, and you are all set.

<img src="<?= $icon ?>"/>
<h3 style="margin-bottom:30px;">It's currently <?= $temp ?>&deg; and <?= $weather ?> in California.</h3>

I am finding the call to take about 0.20s, which is acceptable to keep it all in PHP right now. Hope this helps in your quest.
