finally done my problem, just add utf8ize function
function utf8ize($d) {
if (is_array($d)) {
foreach ($d as $k => $v) {
$d[$k] = utf8ize($v);
}
} else if (is_string ($d)) {
return utf8_encode($d);
}
return $d;
}
and use it for json_encode
$response["success"] = 1;
$response["message"] = "Successfully Displayed";
$response["page"] = $halaman;
$response["total_pages"] = $totalpages;
$data = json_encode(utf8ize($response));
echo $data;
