使用XMLReader解析

$url = &#39;http://weather.yahooapis.com/forecastrss?w=15015432&u=c&#39;;
$reader = new XMLReader();
$reader->open($url,&#39;utf-8&#39;);
while($reader->read()){
    if($reader->name == &#39;yweather:condition&#39;){
        $code = $reader->getAttribute(&#39;code&#39;);   //获取天气代码
        $temp = $reader->getAttribute(&#39;temp&#39;);   //获取温度
    }
    if($reader->name == &#39;yweather:atmosphere&#39;){
        $humi = $reader->getAttribute(&#39;humidity&#39;);   //获取湿度
    }
}

使用DOMDocument解析

$url = &#39;http://weather.yahooapis.com/forecastrss?w=15015432&u=c&#39;;
$yweather = "http://xml.weather.yahoo.com/ns/rss/1.0";  //命名空间
$res = new DOMDocument();
$res->load($url);
 
$node = $res->getElementsByTagNameNS($yweather, &#39;atmosphere&#39;);
$humi = $node->item(0)->attributes->item(0)->nodeValue;     //获取湿度
$node = $res->getElementsByTagNameNS($yweather, &#39;condition&#39;);
$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

将数字格式的天气代码转换成相应的中文

function code2char($code){
    switch($code){
        case 0:
            return &#39;龙卷风&#39;;
        case 1:
