The slash is not needed:
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

It's better to use fastcgi_split_path_info:

    location ~ ^(.+\.php)(.*)$ {
        fastcgi_split_path_info         ^(.+\.php)(.*)$;
        fastcgi_param  SCRIPT_FILENAME  /path/to/php$fastcgi_script_name;
        fastcgi_param  PATH_INFO        $fastcgi_path_info;

or named captures:

    location ~ ^(?<script_name>.+\.php)(?<path_info>.*)$ {

        fastcgi_param  SCRIPT_FILENAME  /path/to/php$script_name;
        fastcgi_param  PATH_INFO        $path_info;
