PHP array_key_exists condition not printing after statement

Question

I am calling an external api endpoint and it returns an XML. I am trying to catch if the the translated json from the xml has a current array key since it does not have an status column so I manually trying to do some condition.

Here is what I tried

My code in transforming xml to json and printing the response

            $parsed_xml = json_encode(simplexml_load_string($response));
            $finalJson = json_decode($parsed_xml,true);
            dd($finalJson);
            if(isset($finalJson['ErrorResponse'])){
               dd('Error response');
            }else{
               dd($finalJson['GetTransportContentResult']['TransportContent']['TransportHeader']['IsPartnered']);
            }

When I run php artisan tinker and call the controller method (without the conditions for checking the response, i used dd($finalJson), here are the outputs

If the response has error, the translated xml becomes like this

array:2 [
  "Error" => array:3 [
    "Type" => "Sender"
    "Code" => "AccessDenied"
    "Message" => "AuthToken is not valid for SellerId and AWSAccountId."
  ]
  "RequestID" => "be9742cd-516b-43f7-9a9e-bee00ad07b4f"
]

But if it is successful the response is

array:2 [
  "GetTransportContentResult" => array:1 [
    "TransportContent" => array:3 [
      "TransportHeader" => array:4 [
        "SellerId" => "AZZQLCSVQ753J"
        "ShipmentId" => "FBA15XJRFN14"
        "IsPartnered" => "true"
        "ShipmentType" => "LTL"
      ]

I dont know if I add the if-else code i wrote, it returns true in tinker and it does not go to print the dd('Error response') I also tried using array_key_exists('Error',$finalJson) but it does the same thing. Can someone tell me if I am doing the correct thing or I missed something. Thanks a lot.

EDIT: @RigsFolly want me to show the raw result of $response, I just used dd($response) and run the method in tinker and these are the results

If the response is success

<GetTransportContentResponse xmlns="http://mws.amazonaws.com/FulfillmentInboundShipment/2010-10-01/">\n

If it has an error

<?xml version="1.0"?>\n
<ErrorResponse xmlns="http://mws.amazonaws.com/FulfillmentInboundShipment/2010-10-01/">\n
  <Error>\n
    <Type>Sender</Type>\n

  </Error>\n
  <RequestID>b0df9b31-fe36-4936-883e-1c8b19157ba9</RequestID>\n
</ErrorResponse>\n

Can you show us the raw $response

The xmlns is a definitions of the document not part of the documents contents.

So you are testing the wrong part of the XML, instead try

if(isset($finalJson['Error'])){
    echo 'Error response';
}else{
    echo $finalJson['GetTransportContentResult']['TransportContent']['TransportHeader']['IsPartnered'];
}

thanks for sharing your answer sir. It kinda works when the result has an error but when it doesnt have an error. It also returns true and not going to the else part. anything i missed?

RiggsFolly Over a year ago

Mhell Anthonet Bitanas Over a year ago

Mhell Anthonet Bitanas Over a year ago
