如何使用googlehttp地理编码

Posted 2021-02-25

$address = '1 Sir Winston Churchill Square';
$city = 'edmonton';
$province = 'alberta';
$country = 'canada';
$postalcode = 'T5J 2R7';
 
// Google Geo Address
$googleAddress = "http://maps.google.com/maps/geo?q=".urlencode($address) .'+'. urlencode($city) .'+'. urlencode($province).'+'. urlencode($postalcode).'+'. urlencode($country)."&output=xml";
 
// Retrieve the URL contents
$googlePage = file_get_contents($googleAddress);
 
// Parse the returned XML file
$xml = new SimpleXMLElement($googlePage);
 
// Parse the coordinate string
list($longitude, $latitude, $altitude) = explode(",", $xml->Response->Placemark->Point->coordinates);
 
// Output the coordinates
echo "Longitude: $longitude, Latitude: $latitude";
