How to fix PHP_SELF (nginx+php-fpm)?

Question

PHP

Hello, friends. When setting up the nginx + php-fpm bundle, I came across an interesting problem: PHP_SELF becomes equal to PATH_INFO. This happens with the following settings:
nginx:

include                    fastcgi_params;

fastcgi_pass               php;
fastcgi_index              index.php;
fastcgi_next_upstream      error timeout;
fastcgi_keep_conn          on;
fastcgi_split_path_info    ^(.+?\.php)(/.*)$;

set $final_path_info       $fastcgi_path_info;
set $final_script_name     $fastcgi_script_name;

try_files                  $fastcgi_script_name = 404;

fastcgi_param              PATH_INFO          $final_path_info;
fastcgi_param              SCRIPT_FILENAME    $document_root$final_script_name;
fastcgi_param              SCRIPT_NAME        $final_script_name;
fastcgi_param              REQUEST_URI        $request_uri;

php.ini:
cgi.fix_pathinfo = 0;
Is set cgi.fix_pathinfo to 1, then the problem is solved. It is also solved if you comment out fastcgi_param PATH_INFO. But both of these solutions are not suitable, since the first slows down the work somewhat, and the second deprives the PATH_INFO variable, which, in my case, is needed.
Is there a way to set everything up fine? Lossless, so to speak.
PS: content of factcgi_params:

fastcgi_param   QUERY_STRING            $query_string;
fastcgi_param   REQUEST_METHOD          $request_method;
fastcgi_param   CONTENT_TYPE            $content_type;
fastcgi_param   CONTENT_LENGTH          $content_length;

fastcgi_param   SCRIPT_FILENAME         $request_filename;
fastcgi_param   SCRIPT_NAME             $fastcgi_script_name;
fastcgi_param   REQUEST_URI             $request_uri;
fastcgi_param   DOCUMENT_URI            $document_uri;
fastcgi_param   DOCUMENT_ROOT           $document_root;
fastcgi_param   SERVER_PROTOCOL         $server_protocol;

fastcgi_param   GATEWAY_INTERFACE       CGI/1.1;
fastcgi_param   SERVER_SOFTWARE         nginx/$nginx_version;

fastcgi_param   REMOTE_ADDR             $remote_addr;
fastcgi_param   REMOTE_PORT             $remote_port;
fastcgi_param   SERVER_ADDR             $server_addr;
fastcgi_param   SERVER_PORT             $server_port;
fastcgi_param   SERVER_NAME             $server_name;

fastcgi_param   HTTPS                   $https if_not_empty;

Check what you have written in the file - fastcgi_params; maybe some lines are doubled.
