I am trying to figure out how to utilize the scanDirectories command.
I have read the documentation

https://phpstan.org/user-guide/discovering-symbols

But there is no clear instructions on where the .neon file is to be placed in the system. So, I put the file in the conf folder in phpstan. I named it phpstan.neon. I added these lines.

includes:
    - vendor/phpstan/phpstan/conf/phpstan.neon

parameters;
   level: 0
   scanDirectories:
      - src
      - library
      - interface

Phpstan still shows these messages.

        298    Function sqlStatement not found.
     ???? Learn more at https://phpstan.org/user-guide/discovering-symbols
        301    Function sqlFetchArray not found.
     ???? Learn more at https://phpstan.org/user-guide/discovering-symbols

These functions are located in the library folder that I put in the .neon file.
Why can’t phpstan locate the function if I have it in the configuration file?
