How can I include an upper folder page in view

Hello there,

I'd like to use a simple view mechanism based on simple include() functions. Here is my file structure:

/resources --/views ----/theme ------/signup --------/form.php

I simply add but it returns "include(../_partials/header.php): failed to open stream: No such file or directory" but actually there is. I complete the file locations with PHPStorm. Anybody can give me a hand? There is not so much about views in the documentation here https://lumen.laravel.com/docs/master no section for Views.
