PHP to obtain the weather of a specified area

Weather query is used when developing the website. Since it is based on WordPress, there are many restrictions. First create a [weather.PHP] file, and then look at the code:

<?php  
//获取天气 
   $url = &#39;http://m.weather.com.cn/data/&#39;;  
   $id = &#39;101181101&#39;; //焦作的代号 
   $data = file_get_contents($url . $id .&#39;.html&#39;);  
 
 $obj=json_decode($data); 
 echo $obj->weatherinfo->city.&#39;：&#39;.$obj->weatherinfo->weather1.&#39; &#39;.$obj->weatherinfo->temp1;

For:

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

can be abbreviated as:

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

And for:

$obj=json_decode($data);

It converts the obtained json data into an object , convenient for calling;

Then the last sentence:

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

is to obtain the specified data and output it in a certain format,

$obj->weatherinfo->city //城市 
$obj->weatherinfo->weather1 //今天的天气 
$obj->weatherinfo->temp1 //今天的气温

Finally where it needs to be displayed

<?php include &#39;weather.php&#39; ?>

That’s it.
