$url = 'http://weather.yahooapis.com/forecastrss?w=15015432&u=c';
$reader = new XMLReader();
$reader->open($url,'utf-8');
while($reader->read()){
	if($reader->name == 'yweather:condition'){
		$code = $reader->getAttribute('code');	//获取天气代码
		$temp = $reader->getAttribute('temp');	//获取温度
	}
	if($reader->name == 'yweather:atmosphere'){
		$humi = $reader->getAttribute('humidity');	//获取湿度
	}
}

2. [代码]使用DOMDocument解析跳至 [1] [2] [3] [全屏预览]

$url = 'http://weather.yahooapis.com/forecastrss?w=15015432&u=c';
$yweather = "http://xml.weather.yahoo.com/ns/rss/1.0";	//命名空间
$res = new DOMDocument();
$res->load($url);

$node = $res->getElementsByTagNameNS($yweather, 'atmosphere');
$humi = $node->item(0)->attributes->item(0)->nodeValue;		//获取湿度
$node = $res->getElementsByTagNameNS($yweather, 'condition');
$code = $node->item(0)->attributes->item(1)->nodeValue;		//获取天气代码
$temp = $node->item(0)->attributes->item(2)->nodeValue;		//获取温度

3. [代码]将数字格式的天气代码转换成相应的中文跳至 [1] [2] [3] [全屏预览]
