Weather forecast has always been a basic function of major websites. Recently, the editor also wanted to have one on the website. After searching on the Internet for a long time, I finally found the open source free weather forecast interface API and all regional codes in the country ( Provided by the National Meteorological Administration), the details are as follows:
Weather forecast interface provided by the National Meteorological Administration
- Get the provincial code: http://www.weather.com.cn/data/list3/city.xml?level=1
-
Get the city code (for example, Anhui is 22): http://www.weather.com.cn/data/list3/city22.xml?level=2
-
Get the area code (for example, Anqing is 2206): http:/ /www.weather.com.cn/data/list3/city2206.xml?level=3
Get the code of Wangjiang County, Anqing City, Anhui Province, which is 220607

- Then add the Chinese code to request the URL: http:// m.weather.com.cn/data/101220607.html to get the local weather.

header("content-type:text/html;charset=utf-8");
$weather = file_get_contents("http://www.weather.com.cn/data/sk/101280601.html");
echo $weather;
