Why can't get xml object from php link?

Question

PHP

My script

$xml = simplexml_load_file('http://www.nbt.tj/ru/kurs/export_xml.php?date=2016-06-18&export=xmlout');
print_r($xml);

Outputs nothing, but the link itself in the browser outputs data.
How do I get this xml object?

Answer 1

start by checking:

echo file_get_contents('http://www.nbt.tj/ru/kurs/export_xml.php?date=2016-06-18&export=xmlout')

because it is possible that the ip is blocked.
Then read how to work with xml. if I'm not mistaken, then in php there is a built-in xml "encoder" and "decoder"
