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

Answer 1

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)
});

Answer 2

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);
    });
});
