PHP Question json return extra characters

I have this code

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, Array("'Content-Type: application/json; charset=utf-8'"));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data_str));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$xmlresult = curl_exec($ch);
$xmlError = $xmlresult;
$json = json_decode($xmlresult, true);

The answer I get into json but I could not convert because the in the beginning answer is, extra characters See example

п»ї{"customerPaymentProfileIdList":[],"customerShippingAddressIdList":[],"validationDirectResponseList":[],"messages":{"resultCode":"Error","message":[{"code":"E00039","text":"A duplicate record with ID 39223758 already exists."}]}}

response header

HTTP/1.1 200 OK
Cache-Control: private
Content-Length: 232
Content-Type: application/json; charset=utf-8
Server: Microsoft-IIS/7.5
X-AspNet-Version: 2.0.50727
X-Powered-By: ASP.NET
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: PUT,OPTIONS,POST,GET
Access-Control-Allow-Headers: x-requested-with,cache-control,content-type,origin,method,SOAPAction
Date: Thu, 04 Feb 2016 09:08:15 GMT
Connection: keep-alive

Because of the extra characters I can not json_decode string. What can be done?

Answer Source

I encountered the same issue when developing my library for accessing their JSON API. In the code that handles the response I had to strip those characters out in order to properly decode the string as JSON.

Line 113:

$this->responseJson = preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $responseJson);
