PHP: RSS Yahoo Weather Parser

Yahoo! Weather menyediakan informasi cuaca hampir semua lokasi di dunia. Informasi cuaca ini bisa diambil melalui RSS yang disediakan oleh Yahoo! Contohnya, informasi cuaca di kota Jakarta, bisa diakses di URL berikut :

http://weather.yahooapis.com/forecastrss?p=IDXX0022&u=c

[sourcecode language=”php”]
function yahooWeatherParser($source) {

//$source = “http://weather.yahooapis.com/forecastrss?p=IDXX0022&u=c”;
$strXml = @file_get_contents($source);
if($strXml == false) return false;

$objRss = simplexml_load_string($strXml);

$objWeather = new SimpleXMLElement($strXml);
$weather[‘condition’] = $objWeather->xpath(“//yweather:condition”);
$weather[‘location’] = $objWeather->xpath(“//yweather:location”);
$weather[‘units’] = $objWeather->xpath(“//yweather:units”);
$weather[‘wind’] = $objWeather->xpath(“//yweather:wind”);
$weather[‘atmosphere’] = $objWeather->xpath(“//yweather:atmosphere”);
