Are you interested in automated source code analysis for identifying potential errors?

Static code analysis tools help identify potential errors, vulnerabilities, and style violations without executing the program. In PHP, common static analyzers include PHPStan, Psalm, and PHPCS.

For example, PHPStan can detect type errors and incorrect function usage early in development, significantly reducing bugs in production.

Example of using PHPStan:

vendor/bin/phpstan analyse src --level=max

This runs code analysis on the src directory with maximum strictness. Such tools are useful for improving code quality and automating checks in CI/CD.
