How to json_encode utf8?

Question

$obj = [{"name":"Hình Ảnh","url":"images"}];
$str = json_encode($obj);

result:

[{"name":"H\u00ecnh \u1ea2nh","url":"hinh_anh"}]

Why?

Why $str not is:

[{"name":"Hình Ảnh","url":"images"}];

Because that's how it is. See JSON_UNESCAPED_UNICODE for the non-standard encoding. — mario, May 09 '15 at 10:19
of course decode it back but in need save string to json file with file_put_contents. — Nguyễn Văn Tiến, May 09 '15 at 10:58

Add your file this code

header('Content-type: text/html; charset=UTF-8') ;

and change

$str = json_encode($obj, JSON_UNESCAPED_UNICODE);

I see, I was do it, but this result with: json_encode($obj, JSON_UNESCAPED_UNICODE); ==> json_encode() expects parameter 2 to be long, string given in note: – Nguyễn Văn Tiến May 09 '15 at 10:51
