apache往Nginx去转，代码端用到了$_SERVER['PATH_INFO']，对于Nginx默认是不开启pathinfo的。所以我们就要手动开启

1，url重写

location / {    //方法1
 if (!-e $request_filename)
 {
 rewrite ^/(.*)$ /index.PHP/$1 last;
 break;
 }
}

location / {   //方法2
 try_files $uri $uri/ /index.PHP$uri;
}

2，pathinfo设置

location ~ .*\.(PHP|PHP5)(.*)?$ //注意这块，配置重写的url
{
 fastcgi_pass 127.0.0.1:9000;
 fastcgi_index index.PHP;
 fastcgi_split_path_info ^(.+\.PHP)(/.+)$;
 fastcgi_param PATH_INFO $fastcgi_path_info;
 fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
 include fastcgi.conf;
}

这块要注意，location后正则要根据重写的url来决定。
