About:
Psalm is a static analysis tool for PHP that detects errors in PHP code by examining the code without running it. It helps developers identify type errors, null pointer exceptions, and other potential bugs before runtime. The tool provides detailed insights into code quality and type safety, making it essential for maintaining large PHP codebases.
Key Features:
  • Type inference and checking
  • Dead code detection
  • Security vulnerability scanning
  • IDE integration
  • Custom rule creation
Use Cases:
  • Continuous integration pipelines for PHP projects
  • Refactoring legacy PHP codebases safely
  • Enforcing coding standards and best practices
Alternatives:
  • PHPStan – Similar static analysis capabilities with different configuration approach
  • Phan – Another PHP static analyzer, often considered slightly less strict by default
