I have something like this:
$url = "http://ws.geonames.org/findNearbyPostalCodes?country=pl&placename=";
$url .= rawurlencode($city[$i]);
$xml = simplexml_load_file($url);
echo $url."\n";
$cityCode[] = array(
'city' => $city[$i],
'lat' => $xml->code[0]->lat,
'lng' => $xml->code[0]->lng
);
It's supposed to download XML from geonames. If I do print_r($xml)
I get :
SimpleXMLElement Object
(
[code] => Array
(
[0] => SimpleXMLElement Object
(
[postalcode] => 01-935
[name] => Warszawa
[countryCode] => PL
[lat] => 52.25
[lng] => 21.0
[adminCode1] => SimpleXMLElement Object
(
)
[adminName1] => Mazowieckie
[adminCode2] => SimpleXMLElement Object
(
)
[adminName2] => Warszawa
[adminCode3] => SimpleXMLElement Object
(
)
[adminName3] => SimpleXMLElement Object
(
)
[distance] => 0.0
)
I do as you can see $xml->code[0]->lat
and it returns an object. How can i get the value?
You have to cast simpleXML Object to a string.
$value = (string) $xml->code[0]->lat;
