API Google Weather

[Pizzair]

Qualcuno la utilizza?
Girando un pò su internet ho trovato pearecchie cose, ho però fatto una piccola modifica personale utilizzando altre immagini.
Non capisco per quale motivo qualche volta si blocca!
La funzione che utillizzo è questa:

<?php
function loadXML2($domain, $path, $timeout = 100) {

    $fp = fsockopen($domain, 80, $errno, $errstr, $timeout);
    if($fp) {
        // make request
        $out = "GET $path HTTP/1.1\r\n";
        $out .= "Host: $domain\r\n";
        $out .= "Connection: Close\r\n\r\n";
        fwrite($fp, $out);
       
        // get response
        $resp = "";
        while (!feof($fp)) {
            $resp .= fgets($fp, 128);
        }
        fclose($fp);
        // check status is 200
        $status_regex = "/HTTP\/1\.\d\s(\d+)/";
        if(preg_match($status_regex, $resp, $matches) && $matches[1] == 200) {   
            // load xml as object
            $parts = explode("\r\n\r\n", $resp);   
            return simplexml_load_string($parts[1]);               
        }
    }
    return false;
}

Qualcuno di voi utilizza pure questa API? Utilizzate una funzione diversa?
Il problema è che non è sempre affidabile, e quando non funziona non si apre nemmeno la pagina, come potrei modificare la funzione?
