Define/include "globally available" arrays and functions

You can place the file anywhere you want as it is not specifically a helper. Helpers' file names should end in `_helper`, like `number_helper.php` for the `helper()` function to work. Since your file is not a helper per se, anywhere is fine as long as you include the full path to the `$files` property.

I created the file "app/own_functions.php" and added the line 

PHP Code:

public $files = [ 'app/own_functions.php', ]; 


in "app/Config/Autoload.php". But the view that is using the function only outputs the error "Call to undefined function".
I tried to change the path inside public $files in various ways (e.g without "app/" only 'own_functions.php'). Still only errors. What's my mistake?
