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);

• Oybek: Are you posting from client and looking for sent data in $_GET array?
• user1077300: yes, I want to get values of arr array in phpscript.
• Oybek: You are posting you should use $_POST array

Answer 1

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

Answer 2

you should use

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

Answer 3

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