$final = array_merge(array('array1'=>$viewEO, array('array2'=>$viewAcara)));

mysql_close($con);

header('Content-Type:application/json');
echo json_encode($final);
?>

Answer 1

You don't need array_merge. Just combine the two arrays into another array:

$final = array('array1'=>$viewEO, 'array2'=>$viewAcara);
header('Content-Type: application/json');
echo json_encode($final);
