调用新浪天气的api(xml格式返回),可以得到xml字符串,可是装载到对象中后却输出不出来,是怎么回事?
getWeather();
class Weather
{
private $apiUrl = 'http://php.weather.sina.com.cn/xml.php?city=%B1%B1%BE%A9&password=DJOYnieT8234jlsK&day=0';
public function getWeather()
{
$xml = file_get_contents($this->apiUrl);
$result = simplexml_load_string($xml);
$weather = $result->pollution;//xml中的一个子节点
return $weather;
}
}
?>

修改为:$weather = $result->Weather->pollution;
