Answer 1

Try to get contents from URL like:
$url = "https://www.bidv.com.vn/ServicesBIDV/ExchangeRateServlet";
$xml = simplexml_load_string(shell_exec("curl -k '$url'"));
echo '<pre>';
print_r($xml);
echo '</pre>';
I see the page you try to get is not XML, its JSON.
This will work:
$url = 'https://www.bidv.com.vn/ServicesBIDV/ExchangeRateServlet';
$data = json_decode(shell_exec("curl -k '$url'"), 1);
echo '<pre>';
print_r($data);
echo '</pre>';
var_dump($data);
