Psalm is an open-source static analysis tool for PHP that finds type-related bugs and security vulnerabilities through type inference and taint analysis. It includes a language server for IDE integration, automatic fixes via Psalter, and a plugin system.
Use cases
- find type errors in php code
- detect security vulnerabilities in php applications
- taint analysis for php
- automatically fix php code issues
- add type checking to a legacy php codebase
- run static analysis in ci for php
- php language server for ide
When to choose
- you maintain a PHP codebase and want to catch type-related runtime errors before they happen
- you need taint analysis to find injection-style security vulnerabilities in PHP
- you want automated fixes and refactoring for missing typehints and common issues
- you want gradual typing with configurable strictness levels for large or legacy codebases
When to avoid
- your project is not written in PHP
- you need runtime profiling or performance analysis rather than static checks
- you want a zero-configuration linter without type annotations or error levels
