PHPStan demo

This repository contains short, easy-to-understand examples of all errors that PHPStan reports, grouped per level.

It can be used to gradually introduce people or teams to what PHPStan has to offer.

Basic usage

Each file in /src holds a few lines of PHP code that will trigger the exact errors PHPStan complains about at that level.

Run PHPStan with:

./vendor/bin/phpstan analyze src/ --level=0

Change the level and see the errors from each of the demo files.

Composer script

composer analyze

Hardcoded at level 0 in composer.json under scripts.

With config file

./vendor/bin/phpstan

Hardcoded at level 9 in phpstan.neon.dist under parameters.
