Why did the simple html dom library stop working?

Question

PHP

Everything was working yesterday. Nothing works today.
This code gave me a copy of the site

$html = str_get_html("www.yandex.ru");
  echo $html;

Now he just writes in the browser www.yandex.ru, and in the title there are some krakozyabry.

Answer 1

str_get_html parses a string to parse the contents of the URL of the page, do not forget to specify the http (s) protocol, otherwise it will look for a file with the name www.yandex.ru in the file system
