How to autoload a non-class .php file

[ahmu83]

I have added psr-4 autoloading in my composer.json like this, and I would like to know how to autoload a non-class .php file. i.e a file that contains just functions.

    "autoload": {
        "psr-4": {
            "App\\": "inc/App"
        }
    }

Everything is working fine but I want to know is there a way to autoload a non-class .php file with namespacing?

i.e, my test-functions.php has a namespace of namespace App\TestFunctions
and I would like this to be included when I do use App\TestFunctions

Is this possible?

PHP does not have an autoloader for functions. They must be loaded before usage.

However, it is possible to tell composer to load some files at the time vendor/autoload.php is included, which is useful for files defining functions (but they will be loaded early, not only when they are used). For that, use the files key under autoload in your config: https://getcomposer.org/doc/04-schema.md#files
