Question

I am trying to send this query:

http://api.geonames.org/search?featureCode=PRK&maxRows=10&username=demo&country=US&style=full&adminCode1=AK

To a web service and pull down and parse a bunch of fields there, namely these:

// 1) totalResultsCount
// 2) name
// 3) lat
// 4) lng
// 5) countryCode
// 6) countryName
// 7) adminName1 - gives full state name
// 8) adminName2 - owner of the park.

I am doing this:

$query_string = "http://api.geonames.org/search?featureCode=PRK&maxRows=10&username=demo&country=US&style=full&adminCode1=AK";

Could someone please provide the right code to loop through the results and get values?

Answer 1

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 />";
}

Which will displays the results as follows:

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