How to get json_encode() to work with ISO-8859-1 (åäö)

Question

json_encode() wont work for me when I\'m using åäö. Why? And how can I get it to work?

The php:

echo json_encode($arr);
         


        

Answer 1

The $data (in my case) is an array with text values as ISO-8859-1. The trick below prepares $data to be used with json_encode.

function toUtf8(&$v, $k) {
    $v = utf8_encode($v);
}
array_walk_recursive($data, 'toUtf8');
