server
{
 listen       80;
 server_name xxx;
 ....if (!-e $request_filename) {
                 rewrite ^/(.*)$ /index.php/$1 last;
  }


  location ~ \.php {
                set $real_script_name $fastcgi_script_name;
                set $path_info "";
                include        fastcgi_params;

                if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
                           set $real_script_name $1;
                           set $path_info $2;
                }


               ...
                fastcgi_param PATH_INFO $path_info;
                fastcgi_param SCRIPT_NAME $real_script_name;
  }
