how to return an array from php to ajax response in javascript

Question

how to return an array in php to ajax call,

ajax call :

$.post('get.php',function(data){
alert(data)

});

get.php

$arr_variable = array('033','23454')
echo  $arr_variable;

in the alert(data), it is displaying as Array (i.e only text), when i display data[0], 1st letter of Array i.e A is displaying.

Any suggestions ? where i have done wrong

use echo json_encode($arr_variable) this will convert your array into json format. — Manibharathi

Use to encode the array like

$data['result'] = $arr_variable;
echo json_encode($data);
exit;

And in the success function try to get it like parseJSON like

$.post('get.php',function(data){
    var res = $.parseJSON(data);
    alert(res.result)
});

Param#2 Should be a bitmask or a depth, not a bool., changed since, but cannot change vote.

@prassu I have updated my answer to be compatible with a dynamic amount of elements in the PHP array, after transmission it will alert each one, one by one.

@gautam3164 You don't need the $.parseJSON as the $.post will automatically trigger that if it detects valid JSON syntax.

@t3chguy no.you have to parse it when you are processing a json data

instead of echo $arr_variable; use echo json_encode($arr_variable); and then in jQuery you can access it like an object.

Once it is an object, you can access it as data[0] and so forth.

$.post('get.php',function(data){
    $.each(data, function(d, v){
        alert(v);
    });
});
