Im trying to send a post parameter to my php file 

```
     <?php
      $sid = $_POST['sid'];
      ini_set( 'error_reporting', E_ALL );
      ini_set( 'display_errors', true );
      include 'dbconfig.php';
      //include 'sql.php';
      //include 'pass.php';

      ob_start();
      include 'pass.php';
      ob_end_clean() ;
      /* if($_SERVER['REQUEST_METHOD']=='POST'){*/ 

      // Create connection
      $conn = new mysqli($servername, $username, $password, $dbname);
      mysqli_set_charset($conn,'utf8');
      if ($conn->connect_error) {
       die("Connection failed: " . $conn->connect_error);
      }
      $sql = "SELECT * FROM lime_questions  where sid=$sid";
      $result = $conn->query($sql);
      if ($result->num_rows >0) {
      // output data of each row
      while($row[] = $result->fetch_assoc()) {
      $tem = $row;
      $json = json_encode($tem, JSON_UNESCAPED_UNICODE);
      }
      } else {
       echo "0 results";
      }
      $data= strip_tags ($json);
      echo str_replace('success','',$data);

      //$encoded=json_decode($json);
      //print_r($encoded);
      //echo json_last_error_msg();

      $conn->close(); 

      ?>

```

the problem that the $sid variable must be sent from my jsonarrayrequest than parse received that , this is my java code :
im using jsonarrayrequest to get data from my server to my app

```
     public void LoadData() {
            Bundle extras = getIntent().getExtras();
            //sid = extras.getString(Login.KEY_URL);
            sid="1994";
            JsonArrayRequest newsReq1 = new JsonArrayRequest(url1, new  
            Response.Listener<JSONArray>() {
                @Override
                public void onResponse(JSONArray response) {
                    for (int i = 0; i < response.length(); i++) {
                        try {

                            JSONObject obj = response.getJSONObject(i);

                            String sqid = obj.getString("sid");
                            String gid = obj.getString("gid");
                            String id = obj.getString("qid");
                            String q = obj.getString("question");
                            String t = obj.getString("type");
                            insertIntoDB(sqid, gid, id, q, t);
                            test.setText(q);
                            NewsQuestions question = new NewsQuestions(id, 
                            q, t);
                            // adding question to questions array
                            questionsList.add(question);

                        } catch (Exception e) {
                            System.out.println(e.getMessage());
                        } finally {

                        }
                    }
                }

            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    System.out.println(error.getMessage());
                }}
            )
            {
                @Override
                protected Map<String, String> getParams() throws 
AuthFailureError {
                    Map<String, String> params = new HashMap<String, String>
();
                    params.put(KEY_URL,sid);

                    return params;
                }

                @Override
                public int getMethod() {
                    try {
                        getParams();
                    } catch (AuthFailureError authFailureError) {
                        authFailureError.printStackTrace();
                    }
                    return super.getMethod();
                }
            };
