Get value from SimpleXMLElement Object

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?
