Ho trovato su internet il codice:
codice:
<?php
/* get xml, find match */
/* get the weather from Yahoo */
$data = get_data("http://weather.yahooapis.com/forecastrss?p=97211&u=c");
$weather_class = format_result(get_match('/<yweather:condition text="(.*)"/isU',$data));
/* debug to see what we got back */
//echo '<pre style="background:#fff;font-size:12px;">['; print_r($weather); echo ']</pre>';
/* format the result */
function format_result($input)
{
return strtolower(str_replace(array(' ', '(', ')'), array('-', '-', ''), $input));
}
/* helper: does regex */
function get_match($regex,$content)
{
preg_match($regex,$content,$matches);
return $matches[1];
}
/* gets the xml data from Alexa */
function get_data($url)
{
$ch = curl_init();
$timeout = 5;
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$xml = curl_exec($ch);
curl_close($ch);
return $xml;
}
?>
ma vorrei che, al posto di un codice postale fisso (97211), ce ne fosse uno variabile in base alla posizione dell'utente (senza bypassare i controlli del browser, ovviamente.
Vi ringrazio in anticipo,
