What is xamppfiles\lib\php for?
And I see that path is in PHP's include_path but it's not set in php.ini so I guess XAMPP includes it internally.
What do those php files do and why are they included by default?
I just installed an application that does include('config.php'); trying to reference a file from the same path, but ends up including xamppfiles\lib\php\config.php instead and has a name clash with class Config.
How can I avoid including XAMPP's php files or otherwise avoid this problem?
