在开发网站的时候用到天气查询,由于是基于 Wordpress 的所以有很多限制,先建一个【 weather.php】 的文件,然后看代码: ?php //获取天气 $url = 'http://m.weather.com.cn/data/'; $id = '101181101'; //焦作的代号 $data = file_get_contents($url . $id

在开发网站的时候用到天气查询,由于是基于Wordpress的 所以有很多限制,先建一个【weather.php】的文件,然后看代码:

<?php //获取天气
     $url = 'http://m.weather.com.cn/data/';  
     $id = '101181101';  //焦作的代号
     $data = file_get_contents($url . $id .'.html');  

  $obj=json_decode($data);
 echo $obj->weatherinfo->city.':'.$obj->weatherinfo->weather1.' '.$obj->weatherinfo->temp1;
Copy after login

对于:

$url = 'http://m.weather.com.cn/data/';  
     $id = '101181101';  //焦作的代号
     $data = file_get_contents($url . $id .'.html');
Copy after login

可简写为:

$data = file_get_contents('http://m.weather.com.cn/data/101181101.html');
Copy after login

而对于:

$obj=json_decode($data);
Copy after login

它是把获取的json数据转化为一个对象,方便调用;

那么最后一句:

echo $obj->weatherinfo->city.':'.$obj->weatherinfo->weather1.'  '.$obj->weatherinfo->temp1;
Copy after login

就是获取指定的数据并按照一定格式输出,
$obj->weatherinfo->city //城市
$obj->weatherinfo->weather1 //今天的天气
$obj->weatherinfo->temp1 //今天的气温
Copy after login

其他参数可以自行访问 http://m.weather.com.cn/data/101181101.html 查看

最后 在需要显示的地方

<?php include 'weather.php' ?>
Copy after login

即可。
