Http://api.map.baidu.com/telematics/v3/weather? Location = Beijing & output = xml & ak = gfPnxaaiPyNIhM7c3eZ1kmEL

In this example, how to assign the currentCity node value to $ city to retrieve all nodes in weather_data cyclically and assign the value to the array? -"$ Date, To $ dayPictureUrl.

Where is the great god?

$ Url = 'http: // api.map.baidu.com/telematics/v3/weather? Location = Beijing & 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 );

Beijing object (SimpleXMLElement) #2 (0) {} array (4) {[0] => string (30) "Friday (today, real-time: 24 ℃) "[1] => string (6)" Saturday "[2] => string (6)" Sunday "[3] => string (6) "Monday"} array (4) {[0] => string (57) "http://api.map.baidu.com/images/weather/day/leizhenyu.png" [1] => string (51) "http://api.map.baidu.com/images/weather/day/yin.png" [2] => string (52) "http://api.map.baidu.com/images/weather/day/qing.png" [3] => string (52) "http://api.map.baidu.com/images/weather/day/qing.png "}

Don't get angry. this is my mistake. it seems that there is a problem with the brackets.

OK. it seems that the data to be written separately cannot be directly echo $ city = $ xml-> xpath ('// currentCity') [0];

Yes.
$ City = $ xml-> xpath ('// currentcity ');
Echo $ city [0];

That's your problem.
Besides, the error information must be fixed. Otherwise, how can someone determine the problem?

Your php version is too low.
$ City = $ xml-> xpath ('// currentcity') [0];
Change
$ City = current ($ xml-> xpath ('// currentcity '));

Cainiao doesn't. sorry, the moderator.

foreach($xml->xpath('//weather_data') as $r) {$date = (array)$r->date;print_r($date);}

Why is there only one row of data written in Beijing?
2014-04-25
Array ([0] => Friday (today, real-time: 24 ℃ ))
It should be Saturday and Sunday.
