新版本的nginx有一个自带的函数可以处理pathinfo，如下：

location ~ .php(.*)$ { fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_index index.php; fastcgi_split_path_info ^(.+.php)(.*)$; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; #include fastcgi_params; include fcgi.conf; }
