I create web service to save data in database

public string SaveData(String resultData) //save data to database
    DLR service = new DLR();
    Context.Response.ContentType = "application/json";
    string filePath = Server.MapPath("~/Error.txt");
    using (StreamWriter writer = new StreamWriter(filePath, true))
        writer.WriteLine("Json is sent :" + resultData +
           "" + Environment.NewLine + "Date :" + DateTime.Now.ToString());
        writer.WriteLine(Environment.NewLine + "-----------------------------------------------------------------------------" + Environment.NewLine);
    RootObject obj = JsonConvert.DeserializeObject<RootObject>(resultData);
        foreach (JsonData item in obj.results)
                var connStr = ConfigurationManager.ConnectionStrings["myCon1"].ConnectionString;
                SqlConnection con = new SqlConnection(connStr);
                    SqlCommand cmd = new SqlCommand("[insert_RDL]", con);
                    cmd.CommandType = CommandType.StoredProcedure;
                    cmd.Parameters.AddWithValue("@msgId", item.msgId);
                    cmd.Parameters.AddWithValue("@status", item.status);
                    cmd.Parameters.AddWithValue("@ttest", "");
                    cmd.Parameters.AddWithValue("@newtest", "");
        return "OK ";

When i post the json by ajax in aspx page or by PHP SoapClient the page is sending json without problem .

But post it by PHP Curl
$data = '{"results": [{"msgId": "001","to": "9665312114","status": "D"}, {"msgId": "859911880","to": "966535112578","status": "N"}, {"msgId": "859911880","to": "966535112579","status": "S"}]}' ;
$param = array('resultData' => $data);
echo "<hr>";
$headers = array('Accept: application/json','Content-Type: application/json', );
echo "<hr>";
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
//curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_URL, "");
curl_setopt($ch, CURLOPT_POSTFIELDS, $param); 

 $result =curl_exec($ch);

echo "<hr>";
if(curl_exec($ch) === false)
    echo 'Curl error: ' . curl_error($ch);
    echo 'Operation completed without any errors';

convert pure json into json string and try

{ \"test\":\"some data\" }

in web service or PHP page

Take a minute and think about the code you've written. Where are you consuming the code that requires you to manipulate the JSON. You are using PHP to access a ASP.NET web service (asmx) so where would it make sense that you need handle the conversion mentioned.

I'm trying to get you to think for yourself instead of attempting to just have answers provided for you, you'll never learn this way.

I read the code well
The variable (resultData) is issued from PHP by cURL is json string

also the variable recived in method (SaveData) is string
So no problem for conversion .
Thank You

in PHP page,json should be in string format,try if it works after converting to JSON string

$data = '{\"results\": [{\"msgId\": \"001\",\"to\": \"9665312114\",\"status\": \"D\"}, {\"msgId\": \"859911880\",\"to\": \"966535112578\",\"status\": \"N\"}, {\"msgId\": \"859911880\",\"to\": \"966535112579\",\"status\": \"S\"}]}' ;
