推荐答案

我' d说这很安全。只是不要允许任何东西写入这些文件夹。 PHP文件传统上位于服务器的Web根目录中，这对于开始是危险的。如果配置错误或.htaccess文件丢失，最好将正在加载的文件放置到外部绝对无法访问的区域。

I'd say it's pretty safe. Just don't allow anything to write to those folders. PHP files are traditionally inside the web root of a server which is dangerous to start with. It would be better to place the files being loaded to an area that's absolutely inaccessible to the outside given a configuration error or a .htaccess file going missing.
