Climatempo to include in the site

The CPTEC website has some services in xml. link

I use a PHP code that connects to the link API, and step as parameters to the city in my case Araci-Bahia, the measure and the language, it returns a JSON after this is only you treat the JSON.

In my case I call this PHP via Ajax, there I do all the processing, iteration, etc.

function get_weather(){
 try{
    $obj = file_get_contents("http://api.openweathermap.org/data/2.5/weather?q=araci,brasil&lang=pt&units=metric");
    $item = json_decode($obj);
    //no meu caso dou a saída para o AJAX onde trato
    return round($item->main->temp);
 }catch(Exception $ex){
       //trata o erro
 }
}
