$url = 'http://api.map.baidu.com/telematics/v3/weather?location=北京&output=xml&ak=gfPnxaaiPyNIhM7c3eZ1kmEL';
$xml = simplexml_load_file($url);
echo $city = $xml->xpath('//currentCity')[0];
foreach($xml->xpath('//weather_data') as $r) {
$date = (array)$r->date;
$dayPictureUrl = (array)$r->dayPictureUrl;
}
var_dump($city, $date, $dayPictureUrl);
北京object(SimpleXMLElement)#2 (0) {
}
array(4) {

string(30) "周五(今天, 实时:24℃)"
[1]=>
string(6) "周六"
