My script is to geocode lat long from Google apis. It works online on my hosting providers server but not on localhost.. WHY??

$latlng = "44.3585230889,8.57745766643";
$lang = "it";
$geocodeURL = "http://maps.googleapis.com/maps/api/geocode/json?latlng=$latlng&sensor=false&language=$lang";

$ch = curl_init($geocodeURL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

if ($httpCode == 200) {
    $geocode = json_decode($result);

    $location   = $geocode->results[0]->address_components[0]->long_name;
    $city       = $geocode->results[0]->address_components[1]->long_name; 
    $province   = $geocode->results[0]->address_components[2]->long_name; 
    $region     = $geocode->results[0]->address_components[3]->long_name;
    $country    = $geocode->results[0]->address_components[4]->long_name;

    $geo_status = $geocode->status;     
    $geo_str    = "$location, $city, $province, $region, $country";
} else {
    $geo_status = "HTTP_FAIL_$httpCode";
    $geo_str    = "Failed: $geo_status";
}

解决方案

It's probably a firewall issue. Curl by default tries to use port 1080, which is probably not open on your localhost / router / ISP.
