            exit(1);
            break;
    }

    return true;
}
function divide($numerator, $denominator)
{
    if ($denominator == 1)
    {
        $error_msg = "unnecessary to divide by one";

        user_error($error_msg);
    }

    return $numerator / $denominator;
}

set_error_handler("myfunction");

echo divide(10, 1);
