Answer 1

There's no real way to do that. __DIR__ is an absolute path to the current file. There are many reasons you need to know this and it cannot be changed.

open_basedir is a directive to restrict what files PHP and Apache have access to in a given site. It's most commonly used in shared hosting environments to keep user A from accessing user B's files.

Answer 2

__DIR__是此代码所在文件的路径。因此，如果您的脚本位于根目录中，则__DIR__可以按您希望的方式工作。
