这是我想要插入数据的Insert.PHP代码   serverdatabase

      <?php
      $response = array();
   $servername = "localhost";
$username   = "root";
$password   = "R00t1975#";
$dbname     = "tikox"; 

$conn = mysqli_connect($servername, $username, $password, 

$dbname);

    if (!$conn)
{
    die("Connection failed: " . mysqli_connect_error());
}


else
{
echo "success";
}

   $userid = isset($_POST['userid']) ? $_POST['userid'] : 

'';

   $surveyno = isset($_POST['surveyno']) ? $_POST

['surveyno'] : '';


  $questionno=isset($_POST['questionno']) ? $_POST

['questionno'] : '';

  $optionno=isset($_POST['optionno']) ? $_POST['optionno']: 

'';



  $query = mysqli_query($connect, "insert into 

answerindividual (userid,surveyno,questionno,optionno) 

values
 ('$userid','$surveyno','$questionno','$optionno') ");



 // check if row inserted or not


 if ($query) {
    // successfully inserted into database
    $response["success"] = 1;
    $response["message"] = "data successfully inserted.";

    // echoing JSON response
    echo json_encode($response);

 } else {
    // failed to insert row
    $response["success"] = 0;
    $response["message"] = "Oops! An error occurred.";

    // echoing JSON response
    echo json_encode($response);
}


mysqli_close($connect);
?>
