         fastcgi_param SCRIPT_FILENAME /home/phpd/www$fastcgi_script_name;
         include /etc/nginx/fastcgi_params;
     }
 }

第一种，最简单的方法：

加上一句

location ~ \.php {
         fastcgi_pass 127.0.0.1:9000;
         fastcgi_index index.php;
         fastcgi_param SCRIPT_FILENAME /var/www/company$fastcgi_script_name;
         fastcgi_param  PATH_INFO $fastcgi_script_name;
         include /etc/nginx/fastcgi_params;
}

第二种方法：(注意：nginx 0.5 版此方法无效)

location ~ \.php
              {
                   fastcgi_pass 127.0.0.1:9000;
                   fastcgi_index index.php;
                   set $path_info "";
                   set $real_script_name $fastcgi_script_name;
                   if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
                        set $real_script_name $1;
                        set $path_info $2;
                   }
                   fastcgi_param SCRIPT_FILENAME /var/html/$real_script_name;
                   fastcgi_param SCRIPT_NAME $real_script_name;
                   fastcgi_param PATH_INFO $path_info;
                   include /etc/nginx/fastcgi_params;
              }
