nginx fastcgi_param参数问题

Question

server {

    listen       80;
    server_name  bug.com ;
    root   "F:/phpstudy/PHPTutorial/WWW/tp5/public";
    location / {
        index  index.html index.htm index.php;
        #autoindex  on;

if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?s=/$1 last;
break;

}
    }
    location ~ \.php(.*)$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_param  PATH_INFO  $fastcgi_path_info;
        fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
        include        fastcgi_params;
    }

}

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
这个是什么意思呢？ $document_root 指哪里的路径 $fastcgi_script_name指哪里的路径
求大神解答

$document_root 指的是框架入口，就是你上面配置的root
$fastcgi_script_name 指的是脚本名称
