hm. might be a problem with encoding :
try to add this after the $mysqli = new mysqli(DB_HOST, 'Elia', '1234', 'test');
:
$mysqli->set_charset("utf8")
if it doesn't work, juste don't use space or special char (like °
) in your row name, it's a very poor practice.
and also, please print out the $row
array :
print_r($row);
