How to make a request from the server to the site and pass authorization?

Question

PHP

I make a request to the site with authorization through the following: But, of course, it doesn’t let me in, how can I log in in this case?
file_get_contents("{ссылка}");

Answer 1

With what authorization?
Through basic auth like this:

$auth = base64_encode("username:password");
$context = stream_context_create(['http' => ['header' => "Authorization: Basic $auth"]]);
$homepage = file_get_contents("http://example.com/file", false, $context );

Answer 2

And for the usual (via html form) - I recommend using curl. Pass POST parameters and save cookie
