jquery - Array passes through ajax but received as string in php -

-



the following jquery code:

 e_val = [];  e_val = ['enroll','reject'];  $.ajax({                 url: 'myurl.php',                 type: 'post',                 datatype: 'text',                 data: {                     reason: 'insert',                     eval: e_val                 },                 success: function (suc) {                     row.remove();                     alert(suc);                 }        });

myurl.php:

$reason = $_post['reason']; $eval = array(); if($reason == "insert"){      $eval = $_post['eval'];      echo $eval[1]; }

and alert is:

n

that's because n @ index value 1 in e_val[0]. can know why array converted string in php page , i'm not able access array elements? in advance.

you can use implode() implode() function returns string elements of array. 

<html>     <head>      <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>         </head>     <body>         <script>                    var  e_val = [];                    var  e_val = ['enroll','reject'];                     console.log(e_val);                     $.ajax({                     url: 'test2.php',                     type: 'post',                     datatype: 'text',                     data: {                         reason: 'insert',                         eval: e_val                     },                     success: function (suc) {                         alert(suc);                     }            });           // alert("dddd");             </script>      </body> </html>

test2.php

 <?php     $reason = $_post['reason'];     $eval = array();     if($reason == "insert"){          $eval = $_post['eval'];          echo implode(', ', $eval );        //  echo "dddd";     }       // echo "dddd"; ?>
