PHPStan

We provide a PHPStan extension out of the box you can include in your phpstan.neon:

includes:
	- vendor/nesbot/carbon/extension.neon
parameters:
	bootstrapFiles:
		# You will also need to add here the file
		# that enable your macros and mixins:
		- config/bootstrap.php

If you're using Laravel, you can consider using larastan which provides a complete support of Laravel features in PHPStan (including Carbon macros). Alternatively to include the neon file, you can install phpstan/extension-installer:

composer require --dev phpstan/phpstan phpstan/extension-installer

Then add the file where your Carbon macros and mixins are defined in the bootstrapFiles entry:

parameters:
	bootstrapFiles:
		- config/bootstrap.php
