Psalm is a static analysis tool for finding errors in PHP applications, built on top of PHP Parser.
It's able to find a large number of issues, but it can also be configured to only care about a small subset of those.
Try a live demo, or install it in your project by following the Quickstart Guide below.
Documentation is available on Psalm’s website, generated from the docs folder.
Install via Composer:
composer require --dev vimeo/psalm
Add a config:
./vendor/bin/psalm --init
Then run Psalm:
./vendor/bin/psalm
The config created above will show you all issues in your code, but will emit INFO issues (as opposed to ERROR) for certain common trivial code problems. If you want a more lenient config, you can specify the level with
./vendor/bin/psalm --init [source_dir] [level]
You can also learn how to suppress certain issues.
A basic rundown of Psalm’s internals can be found in docs/how_psalm_works.md.
