php - How can I have phpstan find my custom extension class?

one text

Solution:

The extension class needs to be loaded in runtime. You can achieve that in two ways:

1. Make the class available for the Composer autoloader. It's usually sufficient to configure section of your composer.json.

2. Create a file called something like phpstan-autoload.php in which you require_once the file with the extension class. And pass the path to the phpstan-autoload.php file as option on the command line when running PHPStan.
