Have you checked automated source code analysis for error detection and potential issues?

Yes, I have used automated source code analysis tools for PHP, such as PHPStan, Psalm, or PHPCS.

They help identify potential errors, coding style violations, and vulnerabilities even before running the application. For example, PHPStan allows detecting type errors and mismatches, which improves code quality and reduces bugs.

Example of using PHPStan:

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

This runs code analysis on the src folder with the maximum strictness level.
