Question

我在服务器中有以下JSON data。我如何仅在SUCCESS中提取“PHP”作为输出，其中SUCCESS是Status的{{1}}内object的结果。即“status”：“SUCCESS”，

data

更新

{  
   "response":{  
      "status":true,
      "statusCode":"0",
      "statusDescription":"Amount Debited",
      "data":{  
         "balanceamount":"528",
         "status":"SUCCESS",
         "statuscode":"0",
         "statusdescription":"Amount Debited",
         "debitedamount":"2",
         "orderid":"hj",
         "refId":"4450"
      }
   },
   "checksum":"23e97234820f5987189245e4216e89425472c2fe2c957749743b21d828efae67"
}

这个$ch = curl_init(); // initiate curl curl_setopt($ch, CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_POST, 1); // tell curl you want to post something curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string); // define what you want to post curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return the output in string format curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); $output = curl_exec ($ch); // execute //echo "Request_Json= ".$data_string; //echo "Response_Json=".$output; echo $output;给了我上面的JSON。但是当我使用你的答案时，我得到输出为空。我做错了什么？

希望这对您有用：

将json_decode用于json字符串

$json= '{  
   "response":{  
      "status":true,
      "statusCode":"0",
      "statusDescription":"Amount Debited",
      "data":{  
         "balanceamount":"528",
         "status":"SUCCESS",
         "statuscode":"0",
         "statusdescription":"Amount Debited",
         "debitedamount":"2",
         "orderid":"hj",
         "refId":"4450"
      }
   },
   "checksum":"23e97234820f5987189245e4216e89425472c2fe2c957749743b21d828efae67"
}';


$arr = json_decode($json);

//print_r($arr);
echo $arr->response->data->status;
/*Output SUCCESS*/
die;

更新：

 $output = curl_exec ($ch); 
 $arr = json_decode($output );
 echo $arr->response->data->status;

$output = '{  
   "response":{  
      "status":true,
      "statusCode":"0",
      "statusDescription":"Amount Debited",
      "data":{  
         "balanceamount":"528",
         "status":"SUCCESS",
         "statuscode":"0",
         "statusdescription":"Amount Debited",
         "debitedamount":"2",
         "orderid":"hj",
         "refId":"4450"
      }
   },
   "checksum":"23e97234820f5987189245e4216e89425472c2fe2c957749743b21d828efae67"
}';
 $json_result = json_decode($output);
echo $json_result->response->data->status;
