Why does simplexml_load_file fail when transferring a site to hosting?

Question

PHP

$xml = 'https://module-electronic.ru'.$cssJsVersion.'&feed=smartprice';
$xmlParse = (array)(simplexml_load_file($xml)->channel);
  var_dump($xml);
  var_dump($xmlParse);

On the local server, everything is parsed well, but when uploaded to the hosting, it gives out:

string(48) " https://module-electronic.ru?v=6&feed=smartprice " array(0) { }

The validator has no complaints about the xml output on this page. A similar code with a different rss on hosting works fine.

Answer 1
