PHP require_once still requires multiple times

My understanding of require_once is that it would prevent multiple PHP files from requiring the same file again. That does not seem to be the case.

functions.php

function myFunction(){}

middleware.php

require_once("functions.php");

app.php

require_once("functions.php");
require_once("middleware.php");

Fatal error: Cannot redeclare myFunction() (previoiusly declared in functions.php....

I wonder if it is requiring a different functions file. Are app.php and middleware.php in the same folder or a different folder?

My suggestion is whenever you use require, include, include_once, or require_once, that you always use absolute paths using __DIR__.

Such as require_once __DIR__.'/path/to/file.php'
