我是这么写的，还可以判断 php 文件是否存在
```
server {
listen 80 default_server;
server_name _;

root /www;
index index.html index.php;

location ~ \.php(/|$) {
fastcgi_pass 127.0.0.1:9000;
fastcgi_split_path_info ^(.+?\.php)(.*)$;
set $real_path_info $fastcgi_path_info;
try_files $fastcgi_script_name =404;
fastcgi_param PATH_INFO $real_path_info;
include fastcgi.conf;
}
}
```
