send an array in javascript to phpscript

Question

In my page I need to send an array in javascript to Phpscript. My code doesn't return a value and does not give an error. How can I do that?

arr[0]='one';
arr[1]='two';
arr[2]='three';
arr[3]='four';

$.post(
       'sort2.php', 
       {data:arr}, 
       function(result) {
                         alert(result[0]);                  
       },
       'json' 
);

In sort2.php

$data=$_GET["arr"];
echo json_encode($data);

Are you posting from client and looking for sent data in $_GET array? — Oybek

You got $_GET and $_POST mixed up in the PHP script.
It should be $_POST['data'], not $_POST['arr'] (the arr array is passed under the key name data in your JavaScript code: {data:arr}.)

You are using POST method to send data. You should read the $_POST array
