如何获取cURL信息(How to get cURL information)

 我有一个cURL脚本，它连接到一个页面： 
 
<?php 
// create curl resource 
$ch = curl_init(); 

// set url 
curl_setopt($ch, CURLOPT_URL, "example.com"); 

//return the transfer as a string 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

// $output contains the output string 
$output = curl_exec($ch); 

// close curl resource to free up system resources 
curl_close($ch);      
?>
 
 该页面提供了如下输出： 
 
{
  "status" : "fail",
  "data" : {
    "error_message" : "Destination address 37428963298746238 is invalid for Network=BTC."
  }
}
 
 如何使用PHP将“error_message”输入$error_message ？ 

I have a cURL script that makes connection to a page:
 
<?php 
// create curl resource 
$ch = curl_init(); 

// set url 
curl_setopt($ch, CURLOPT_URL, "example.com"); 

//return the transfer as a string 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

// $output contains the output string 
$output = curl_exec($ch); 

// close curl resource to free up system resources 
curl_close($ch);      
?>
 
And that page gives an output like:
 
{
  "status" : "fail",
  "data" : {
    "error_message" : "Destination address 37428963298746238 is invalid for Network=BTC."
  }
}
 
How do I get "error_message" to $error_message with PHP?
