nginx地址重定向后执行php框架的疑惑

[allen0228]

config的配置文件部分内容如下：

    location /ci/ {
        if (!-e $request_filename) {
            rewrite ^/ci/(.*) /ci/index.php last;
        }
        # First attempt to serve request as file, then
        # as directory, then fall back to index.html
        try_files $uri $uri/ /index.html;
        # Uncomment to enable naxsi on this location
        # include /etc/nginx/naxsi.rules
    }
    
    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }

fastcgi_params

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     $request_filename;
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   GATEWAY_INTERFACE   CGI/1.1;
fastcgi_param   SERVER_SOFTWARE     nginx/$nginx_version;

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;

fastcgi_param   HTTPS           $https;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param   REDIRECT_STATUS     200;

执行如下的URL
http://192.168.30.129/ci/welcome

首先地址重定向为 http://192.168.30.129/ci/index.php
基于上面的配置
如果解析到php配置那块，以.php为结束，那welcome这个url中的参数是如何处理的呢

望理解的人告知，到底这个地址重定向如何理解

尽然没有人回复，自己顶下

了解Pathinfo以及框架url路由原理，你就知道了。
