PHP

PHP has been tried out recently but is not much tested yet. Feel free to try it out and report any issues you find.

For PHP, the top level packages are defined within the composer file. The scanner goes into those declared locations, and checks the directories content for use statements.

use Laravel\Cashier\Exceptions\InvalidCoupon;

Only those use statements are taken into account regarding the dependencies. Therefore you have to have the autolaoder setup.
