Ideally you should be using an autoloader Phalcon provides for automatically loading classes.
For non-classes, did you try using full path?
include __DIR__ . "/../functions/facebook.php";
Question
my file structure for phalcon is something like this
--app
-----controllers
-----models
-----views
-----functions
-----libraries
where functions and libraries folder contains some third party scripts like facebook log in etc, when I include the script in my controller classes, I did
include "../functions/facebook.php"
but it gives a file not found error.
How should I include files in the controller classes?
