PHP How to get url and load it xml

I am trying to send this request:

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

Into a web service and pull and analyze a bunch of fields, namely:

// 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'm doing it:

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

Can someone please provide the correct code to view the results and get the values?

Since the answer 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 displays the results as follows:

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

First of all, it seems like the web service is returning XML, not JSON. You can use SimpleXML to parse this.

Secondly, you can check curl

Example:

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

curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$content = curl_exec($ch); 

curl_close($ch);

fopen , . json-, . - file_get_contents.

$query = 'http://api.geonames.org/search?featureCode=PRK&maxRows=10&username=demo&country=US&style=full&adminCode1=AK';
$response = file_get_contents($query);
// You really should do error handling on the response here.
$decoded = json_decode($response, true);
echo '<p>Decoded: '.$decoded['lat'].'</p>';
