How to check for xml file upload?

Question

PHP

I load the xml file of currencies using

$xml = simplexml_load_file('url из интернета');
$usd = (string)$xml->Valute[10]->Value;
$eur = (string)$xml->Valute[11]->Value;

But when there is no internet connection, an error is displayed

Warning: simplexml_load_file(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in /home/leni_m/www/lk.local/public_html/views/template/header.php on line 2

Warning: simplexml_load_file(url из интернета): failed to open stream: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in /home/leni_m/www/lk.local/public_html/views/template/header.php on line 2

Warning: simplexml_load_file(): I/O warning : failed to load external entity "url из интернета" in /home/leni_m/www/lk.local/public_html/views/template/header.php on line 2

How can you avoid throwing an error?
PS The very first line for some reason returns an error, not false
$xml = simplexml_load_file('url из интернета');
