PHPStan Getting Started

When to use

• The user wants to choose or raise a PHPStan analysis level (0 through 10) for their code.
• The user wants to write or edit a phpstan.neon config to set paths, level, includes, or ignore rules.
• The user wants to install PHPStan and run static analysis on a PHP codebase for the first time.

When NOT to use

• Do not use PHPStan to enforce code style, spacing, or formatting; use a fixer such as PHP-CS-Fixer or PHP_CodeSniffer instead.
• Do not reach for PHPStan to verify runtime behavior or business logic; write unit or feature tests for that.
