nginx fast_cgi设置$_SERVER中索引中变量

fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

这种配置如果执行的话， 在php中可以用$_SERVER['PATH_INFO']、$_SERVER['PATH_TRANSLATED']、$_SERVER['SCRIPT_FILENAME']来访问
