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;
对于:
$url = 'http://m.weather.com.cn/data/'; $id = '101181101'; //焦作的代号 $data = file_get_contents($url . $id .'.html');
可简写为:
$data = file_get_contents('http://m.weather.com.cn/data/101181101.html');
而对于:
$obj=json_decode($data);
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;
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
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' ?>
即可。
