回复内容: 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; } } ?>
$weather = $result->pollution;//xml中的一个子节点
修改为:
$weather = $result->weather->pollution;
