由于响应为XML，因此您可以使用

Since the response is XML, you can use SimpleXML:

$url = "http://api.geonames.org/search?featureCode=PRK&maxRows=10&username=demo&country=US&style=full&adminCode1=AK";
$xml = new SimpleXMLElement($url, null, true);

echo "totalResultsCount: " . $xml->totalResultsCount . "<br />";

foreach($xml->geoname as $geoname) {
    echo $geoname->toponymName . "<br />";
    echo $geoname->lat . "<br />";
    echo $geoname->countryCode . "<br />";
    echo $geoname->countryName . "<br />";
    echo $geoname->adminName1 . "<br />";
    echo $geoname->adminName2 . "<br />";
}

将显示以下结果:

totalResultsCount: 225
Glacier Bay National Park and Preserve
58.50056
US
United States
Alaska
US.AK.232
