How to solve php encoding problem?

Question

PHP

I am writing a parser of goods from an XML file,
if you follow the debugging in phpStorm, then everything is ok, there are Russian letters,

but when I output (var_dump) to the browser, I see the following

krakozyabry ... Lebedev's
decoder says that CP1251 should be translated into UTF-8 and everything will be readable again, but I did it through iconv and still see crooks, but others.
maybe I just need to send some kind of header to the browser, tell me why this is happening and how to fix it

Answer 1

header('Content-type: text/html; charset=utf-8');
