Trying to populate a drop down list with jquery and ajax

Here's my code :- 

  <script>
           $(document).ready(function(){                               //#This script uses jquery and ajax it is used to set the values in
           $("#day").change(function(){             //# the time field whenever a day is selected.

           var day=$("#day").val();
           var doctor=$("#doctor").val();

           $.ajax({
                 type:"post",
                 url:"time.php",
                 data:"day="+day+"&doctor="+doctor,
                 dataType : 'json', 
                 success:function(data){
                            var option = '';
            $.each(data.d, function(index, value) {
                option += '<option>' + value.res + '</option>';
                });
            $('#timing').html(option);
                             }

                  });

                  });

                 });
   </script>

And here's the php script.

  <?
    $con=mysqli_connect("localhost","clinic","myclinic","myclinic");
    // Check connection

    if (mysqli_connect_errno())
    {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }

    $doctor = $_POST['doctor'];

    $day = $_POST['day'];

    $query="SELECT * FROM schedule WHERE doctor='" .$doctor."'AND day='" .$day. "'";

    $result = mysqli_query($con, $query);

    $i = 0;                                 //Initialize the variable which passes over the array key values

    $row = mysqli_fetch_assoc($result);    //Fetches an associative array of the row
    $index = array_keys($row);             // Fetches an array of keys for the row.

    while($row[$index[$i]] != NULL)
    {

        if($row[$index[$i]] == 1) {
            $res = $index[$i];              
            echo json_encode($res);

        }
        $i++;
    }       



  ?>

I want options with time values inserted inside a select on my html page which looks something like this :-

  <select id="timing" name="timing"></select>

My java script code is posting values to the php script alright but the code is still not working. There aren't any errors in my javascript as I see it. Kindly help me out
