从SimpleXMLElement对象获取值
我有这样的事情:
$url = "http://ws.geonames.org/findNearbyPostalCodes?country=pl&placename=";$url .= rawurlencode($city[$i]);$xml = simplexml_load_file($url);echo $url."\n";$cityCode[] = array( 'city' => $city[$i], 'lat' => $xml->code[0]->lat, 'lng' => $xml->code[0]->lng);
它应该从geonames下载XML。如果我这样做,print_r($xml)
我得到:
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 )
我可以看到$xml->code[0]->lat
,它会返回一个对象。我怎样才能获得价值?
