ReST API返回11以及JSON成功数据

Question

I have written an API for updating the User information using the PUT method & here is the cURL code :

    $postData = http_build_query($data);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $curlUrl);
    //curl_setopt($ch, CURLOPT_PUT, true);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json'));
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
    curl_setopt($ch, CURLOPT_POSTFIELDS,$postData);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $response  = curl_exec($ch);
    curl_close($ch);
    return $response;

Here $data is the Associative array (key=>value pair). After the request is done in the API end. I'm getting the response as :

11{"Status":200,"Response":"Success","ResponseData":"User Information updated successfully"}

Here, in the response. I'm not able to figure out why that integer value 11 is coming. Please do provide the reason & how to fix it.

thanks in advance, Srinivasu....

Answer 1

In that API function 11 is attaching, means there should be some echo before you are sending proper response. So, please go through your code and comment extra echo that will solve your Problem.

EDIT

This 11 may be before you are actually sending/returning response.
