Why do some frameworks use a longer include syntax?
include-path, php
Solution
`__DIR__` is a magic constant, relative to the current script's file. The dot `.`, however, is relative to the current working directory, that could have been altered by `chdir()`, for instance.
Problem
It seems the following two code styles do the same job: ``` require_once './foo.php'; require_once './../bar.php'; require_once __DIR__.'/foo.php'; require_once __DIR__.'/../bar.php'; ``` Clearly, the first form is shorter and cleaner. However, I see the second form in a lot of third party codes. Is there any reason to prefer the second form?
