php - Getting extra values in json while fetching from MySQL -


i trying fetch data ajax call via json , access data after successful ajax call. purpose, wrote following code :

<?php      error_reporting(e_all);     ini_set('display_errors', 1);     require_once('../include/functions.php');      // session_start();      if( isset($_post['bike_id']))     {         $rows = array();         // echo " in isset";         $bike_id = $_post['bike_id'];         // $modal_name = $_post['modal_name'];         // $json['insertmodal'] = false;          // json_decode($modal_name);         json_decode($bike_id);          $result = selectbike_modal($bike_id);          while ( $row = mysqli_fetch_array($result))         {             $rows[] = $row;         }         echo json_encode($rows);     }     else     {         echo "bike_id not set";     } ?>

now want access via javascript :

$('#choose_bike').on('blur',     function (e) {         e.preventdefault();             var bike_id = $('#choose_bike').val();         //     var modal_name = $('#modal_name').val();         //     // alert("bike_id " + bike_id);             alert("on blur clicked.");             if ( bike_id == "select bike")             {                 $('#defaulterror').addclass("alert alert-danger");                 $('#defaulterror').text("please choose bike");              }             else             {                 // alert("bike : " + bike_id);                 $.ajax(                 {                     url:'../admin/backend/getmodal.php',                     type:'post',                     data: { bike_id: bike_id},                     datatype:"json",                      success:function(data)                     {                         alert(" in success");                         var obj = json.parse(data);                         alert("object " +obj);                     },                     error : function() { console.log(arguments); }                  }                );             }      });

i have 2 issues :

  1. i not getting after :

    alert(" in success");

means following not working :

 var obj = json.parse(data);  alert("object " +obj);
  1. the php response follows:

[{"0":"5","bike_modal_id":"5","1":"shahjahan","bike_modal_name":"shahjahan","2":"30","bike_id":"30"},{"0":"6","bike_modal_id":"6","1":"ram","bike_modal_name":"ram","2":"30","bike_id":"30"}]

i getting

"0":"5","bike_modal_id":"5"

extra. please me parse json correctly in javascript , getting required ajax values.

edit :

select bike_model looks :

function selectbike_modal($bike_id)     {         include("connectvars.php");         $query = "select * bike_model bike_id = '$bike_id'";         $result = mysqli_query($dbc,$query)         or die('error in fetching');          // if ( mysqli_num_rows($result))         //  return 0;         // else             return $result;         // if ( () )         // {         //  return $result;         // }         // else         // {         //  return 0;         // }      }

issue 1
since set datatype:"json" in ajax properties, parsing returned data json.parse() not needed, returned data object. can access objects doing data[0].bike_modal_name.

issue 2
issue of duplicate values, ie. "0":"5","bike_modal_id":"5" because default mysqli_fetch_array() fetches result row both associative , numeric array. can either change 

while ( $row = mysqli_fetch_array($result))

to 

while ( $row = mysqli_fetch_array($result, mysqli_assoc))

or 

while ( $row = mysqli_fetch_assoc($result))

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
