Question 2

PHPStan vs Psalm: which is better for PHP?

PHPStan focuses on rigorous static type checking with strong extensibility, while Psalm offers similar analysis but with different inference algorithms. PHPStan is often preferred for its ecosystem, but Psalm might handle dynamic code better; try both on your codebase to decide.

How to reduce false positives in PHPStan?

Adjust the analysis level in configuration, use precise PHPDoc annotations, and leverage ignore patterns in the config file. The user guide provides tips on tuning sensitivity to minimize unnecessary errors.

Question 4

Can PHPStan analyze WordPress plugins effectively?

Accepted Answer

Yes, with extensions like phpstan-wordpress, it can handle WordPress-specific code. However, due to WordPress's dynamic nature, you may need custom stubs or configurations to cover all edge cases.

Question 5

What's the performance impact of PHPStan on large projects?

Accepted Answer

PHPStan can be slow on big codebases, but you can enable caching and run it incrementally. The Pro version's continuous analysis mode helps by scanning changed files in the background to reduce overhead.

Question 6

Is PHPStan Pro worth the cost for small teams?

Accepted Answer

For small teams, the open-source version is often sufficient. PHPStan Pro adds convenience features like a web UI and watch mode, which might be valuable if you need real-time feedback and can afford the 7 EUR/month individual plan after the free trial.
