Jquery array cannot access in php script Error: Undefined Index

Question

I am sending a javascript array by using jquery to a php script. In ajax I have a myarr variable but this variable can't be accessed in php. Error is :

Undefined index myarr

Please Please help me. this is really important.

This is my jquery code:

for (var n = 0; n < arraySubId.length; n++) {
     var ansArr = [];
     for (var m = 1; m <= 11; m++) {
         ansArr[m - 1] = $('#' + arraySubId[n] + '-' + m + '').val();
     }

     * $.ajax({
         type: 'POST',
         data: ({
             'sub_id': arraySubId[n],
             'myarr': ansArr
         }),
         url: 'Scripts/insert_feedback.php',
         success: function(data) {
             if (data == "1") {

             } else {
                 alert(data);
             }
         }
     }); *
 }

When I access myarr variable in php, it's displaying:

Undefined index myarr.

Please Please help me.

And this is my php code:

<?php

    session_start();

    $prn = $_SESSION['username'];

    $sub_id = $_POST['sub_id'];

    $ans_arr = $_REQUEST['myarr'];

    include 'dbclass.php';

    $dbclass = new DBClass;

    $mysqli = $dbclass->connect();

    $query = "INSERT INTO ".$sub_id."(student_prn, q1, q2, q3, q4, q5, q6, q7, q8, q9, q10, q11, date) values('$prn', '$ans_arr[0]','$ans_arr[1]','$ans_arr[2]',
                                            '$ans_arr[3]','$ans_arr[4]','$ans_arr[5]','$ans_arr[6]',
                                            '$ans_arr[7]','$ans_arr[8]','$ans_arr[9]','$ans_arr[10]', now())";

   $msg = $dbclass->insert($query);

   echo $msg;

?>

Try to convert your array to Json String and send it in JS, and in PHP decode it using json_decode()

Sorry but this is not possible in this case because lot of data going to be generated dynamically Sorry – Sagar Yadav Jan 31 '16 at 19:33
Why you use $_POST['']; for "sub_id" data, and $_REQUEST for "myarr" ? – Dahman S Jan 31 '16 at 19:35
