Extra garbage values added when posting JSON data using cURL

I am trying to create an API using cURL & JSON. Now In my first PHP file I am sending data as JSON data, Like below:

public function index()
{
    $url = 'http://172.24.130.50/testbiz/server/login';

    $field_string = "{“Request”: “Login”, “Username”: anonymous, “APIAccessKey”: “AW342FFGRTR56RTH”, “GMT-Timestamp”: “1489670000”}";
    $json =  json_encode($field_string);
    //open connection
    $ch = curl_init();

    //set the url, number of POST vars, POST data
    curl_setopt($ch,CURLOPT_URL, $url);
    curl_setopt($ch,CURLOPT_POST, 1);
    curl_setopt($ch,CURLOPT_POSTFIELDS, $json);



    //execute post
    $result = curl_exec($ch);


    echo "<pre>".$result."</pre>";

    //close connection
    curl_close($ch);
}

But on my SERVER where I get this request when I show (using var_export()) the values:

public function login()
{

    $client_data = $this->input->post();


    var_export($client_data);

}

Error:

array ( '"{\u201cRequest\u201d:\u201cLogin\u201d,\u201cUsername\u201d:\u201cBIZRTC\u201d,\u201cAPIAccessKey\u201d:\u201cAW342FFGRTR56RTH\u201d,\u201cGMT-Timestamp\u201d:_\u201c1489670000\u201d}"' => '', 0 => '', )

Even if I decode it there I still get \u. Also I dont understand how are these values appended : at starting : '"{\\u201c and this \\u201d}"' => '', 0 => '', at the back.

What are these values?

How do I decode this JSON?

Am I Posting right data to Server?

Updated code

Client.php

public function index()
{
    $url = 'http://172.24.130.50/testbiz/server/login';


    $field_string = array("reqest"=>"login", "user_name"=> "anonymous", "API_AccessKey"=> "AW342FFGRTR56RTH", "GMT_Timestamp"=> "1489670000");
    $json =  json_encode($field_string);

    //open connection
    $ch = curl_init();

    //set the url, number of POST vars, POST data
    curl_setopt($ch,CURLOPT_URL, $url);
    curl_setopt($ch,CURLOPT_POST, 1);
    curl_setopt($ch,CURLOPT_POSTFIELDS, $json);

    //execute post
    $result = curl_exec($ch);


    echo "<pre>".$result."</pre>";

    //close connection
    curl_close($ch);
}

Server.php

public function login()
{


    var_export($_POST);



}

if you are storing json string in variable then you don't need the json_encode() because it is used to convert array to json string. 

    $field_string = '{“Request”: “Login”, “Username”: anonymous, “APIAccessKey”: “AW342FFGRTR56RTH”, “GMT-Timestamp”: “1489670000”}';
        $json =  $field_string;
//open connection
    $ch = curl_init();

    //set the url, number of POST vars, POST data
    curl_setopt($ch,CURLOPT_URL, $url);
    curl_setopt($ch,CURLOPT_POST, 1);
    curl_setopt($ch,CURLOPT_POSTFIELDS, $json);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($json))                                                                       
);

it is because of below line

$field_string = "{“Request”: “Login”, “Username”: anonymous, “APIAccessKey”: “AW342FFGRTR56RTH”, “GMT-Timestamp”: “1489670000”}";
    $json =  json_encode($field_string);

suppose to be like this

$field_string = array("reqest"=>"login", "user_name"=> "anonymous", "API_AccessKey"=> "AW342FFGRTR56RTH", "GMT_Timestamp"=> "1489670000");
    $json =  json_encode($field_string);

You need to give array in json_encode, Instead of string.

Replace: 

 $field_string = "{“Request”: “Login”, “Username”: anonymous, “APIAccessKey”: “AW342FFGRTR56RTH”, “GMT-Timestamp”: “1489670000”}";
    $json =  json_encode($field_string);

To:

$field_string= '{
   "Request": "Login",
   "Username": "anonymous",
   "APIAccessKey": "AW342FFGRTR56RTH",
   "GMT-Timestamp": "1489670000"
}';

Problems in code:

  1. Incorrect json.
  2. Invalid quotes(”) in json.
  3. Passing string in json_encode.
