nginx模式不支持pathinfo模式，類似info.php/hello形式的url會被提示找不到頁面。下面的通過正則找出實際文件路徑和pathinfo部分的方法，讓nginx支持pathinfo。

location ~ /.php$ {root      html;fastcgi_pass  127.0.0.1:9000;fastcgi_index index.php; ##通過設置模擬出pathinfoset $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 $document_root$real_script_name;fastcgi_param SCRIPT_NAME $real_script_name;fastcgi_param PATH_INFO $path_info; include    fastcgi_params;}

要點：

1.~ /.php 后面不能有$  以便能匹配所有 *.php/* 形式的url
2. 通過設置更改 SCRIPT_FILENAME

我在實際使用張將這段代碼融合到了fastcgi_params中。下面是我的nginx配置文件示例：
配置虛擬主機部分，支持pathinfo的nginx代碼如下：

## 在nginx.conf的server部分：

server {listen    8080;server_name localhost; location ~ /.php {include    fastcgi.conf;}}

##要點： /.php 后面沒有$，以便匹配所有 *.php/* 形式
##重點代碼見 fastcgi.conf 開頭部分

fastcgi.conf 代碼如下：

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 $document_root$real_script_name;fastcgi_param SCRIPT_NAME $real_script_name;fastcgi_param PATH_INFO $path_info;## 以上是支持pathinfo的重點部分fastcgi_param GATEWAY_INTERFACE CGI/1.1;fastcgi_param SERVER_SOFTWARE  nginx;fastcgi_param QUERY_STRING    $query_string;fastcgi_param REQUEST_METHOD   $request_method;fastcgi_param CONTENT_TYPE    $content_type;fastcgi_param CONTENT_LENGTH   $content_length;#fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;#fastcgi_param SCRIPT_NAME    $fastcgi_script_name;fastcgi_param REQUEST_URI    $request_uri;fastcgi_param DOCUMENT_URI    $document_uri;fastcgi_param DOCUMENT_ROOT   $document_root;fastcgi_param SERVER_PROTOCOL  $server_protocol;fastcgi_param REMOTE_ADDR    $remote_addr;fastcgi_param REMOTE_PORT    $remote_port;fastcgi_param SERVER_ADDR    $server_addr;fastcgi_param SERVER_PORT    $server_port;fastcgi_param SERVER_NAME    $server_name;# PHP only, required if PHP was built with --enable-force-cgi-redirect#fastcgi_param REDIRECT_STATUS  200;

自己的配置：

server{listen    80;server_name www.touchopenid.com;index index.html index.htm index.php;root /data0/htdocs/openid; location ~ /.php($|/) {set $script   $uri;set $path_info "";if ($uri ~ "^(.+/.php)(/.+)") {set $script   $1;set $path_info $2;}fastcgi_pass  127.0.0.1:9000;include    fastcgi_params;fastcgi_param PATH_INFO        $path_info;fastcgi_param SCRIPT_FILENAME     $document_root$script;fastcgi_param SCRIPT_NAME       $script;}
