show_error() to JSON

Hi Guys,

Is there any way to get a JSON Version of "show_error" method?

Thanks

Something like this?

PHP Code:

function show_error_json( $message )
{
    $status = array();
    $status["success"] = FALSE;
    $status["message"] = $message;

    header("Content-Type: application/json");

    echo json_encode($status);
    exit;
}
