如何将json响应转换为php对象？

Question

Below is my json response, I am using json_decode for converting the response in php object, 'status' and 'msg' is converted successfully but problem is with 'amt'. How to get 'amt' in php object? $amt=$response->transaction_details['amt']; is not working.

RESPONSE :

{"status":1,"msg":"Transactions Fetched Successfully","transaction_details":{"686868686505":{"payid":"293642892","amt":"10.00","txnid":"686868686505","additional_charges":"0.00","productinfo":"SHIRT","firstname":"WILLIAM}}}

CODE :

$response = json_decode($o,true);
$msg = $response['msg']; 
$status = $response['status'];
$amt=$response->transaction_details->['amt'];
echo '<br>';
echo $amt;
echo '<br>';
echo $msg;
echo '<br>';
echo $status;

OUTPUT :

Transactions Fetched Successfully

Answer 1

you are mixing arrays with object.

json_decode second parameter will let you to get json object or json array, it will return json object if it is null or false, and return json array if you set the second parameter to true or anything that translate to true.

see the documentation of it in php.net

that so, you need to change it to:

$response = json_decode($o); // or json_decode($o, false);
$msg = $response->msg; 
$status = $response->status;
//since you use all numbers for json property, I'll assume this would fail
$amt=$response->transaction_details->686868686505->amt;
echo '<br>';
echo $amt;
echo '<br>';
echo $msg;
echo '<br>';
echo $status;

or if you like using array

$response = json_decode($o,true);
$msg = $response['msg']; 
$status = $response['status'];
$amt=$response['transaction_details']['686868686505']['amt'];
echo '<br>';
echo $amt;
echo '<br>';
echo $msg;
echo '<br>';
echo $status;
