Using the standard method when reading from MySQL:

$resultArray = array();
while($obj = MySQL_fetch_object($res)) {
 $resultArray[] = $obj;
}
$result = json_encode($resultArray);

The encoding can be done using the following:

$resultArray = array();
while($obj = MySQL_fetch_object($res)) {
 foreach($obj as $key => $value) {
  if (!is_null($value)) {
   $obj->$key = utf8_encode($value);
  }
 }
 $resultArray[] = $obj;
}
$result = json_encode($resultArray);

The if is_null has to be included so that null fields (e.g., DateTime fields) remain null in the output.
