Kan json niet uit mysql varchar halen, maar int

De regel wijzigen $json['news'][]=$row; naar $json['news'][]=array_map('utf8_encode', $row); probleem opgelost. Er bestaan ​​tekens zoals ä, ö.... in de databasetabel.

$con=mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

$sql = "SELECT `titel` FROM `news` ORDER BY `datum` DESC";
$result = mysql_query($sql);
$json = array();

if(mysql_num_rows($result)){
while($row=mysql_fetch_assoc($result)){

$json['news'][]=array_map('utf8_encode', $row);
}
}
mysql_close($con);
echo json_encode($json);
