Question about how PHP resolve current directory (".")

parent::__construct(); doesn't exist, you need to call parent::Controller();

I think if it is declared as parent::Controller(), calling parent::__construct() will works fine (and no difference). Reference.

realpath() returns the working directory, which is normally the location of index.php. If that's not the case, the working directory is being changed at some point: http://php.net/manual/en/function.chdir.php

Ah yes, getcwd() also tells that working directory have been changed. It's the issue with the library I'm using then. Thanks !
